For the first time in decades, it's hard to ignore the threat of nuclear war. But as long as you're far from the blast, you're safe, right? Wrong. In this sobering talk, atmospheric scientist Brian Toon explains how even a small nuclear war could destroy all life on earth -- and what we can do to prevent it. A professor in the Department of Atmospheric and Oceanic Sciences at the University of Colorado-Boulder, Brian Toon investigates the causes of the ozone hole, how volcanic eruptions alter the climate, how ancient Mars had flowing rivers, and the environmental impacts of nuclear war. He contributed to the U.N.’s Nobel Peace Prize for climate change and holds numerous scientific awards, including two NASA medals for Exceptional Scientific Achievement. He is an avid woodworker.

Fracking explained in five minutes. Fracking is a controversial topic. On the one side the gas drilling companies, on the other citizen opposed to this drilling method. Politicians are also divided on the matter. We try to take a neutral look on fracking. It is relevant for all of us, because of high prices for energy and the danger for our drinking water. This video focuses mostly on the debate currently ongoing in europe. In a lot of european countries there is a public outcry against fracking, espacially in germany. But the facts in this video are relevant to all of us. Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking.

Some of the craziest things will wash up after a big storm like an entire yacht on top of a building and soccer ball across the country! Subscribe to Talltanic http://goo.gl/wgfvrr 6. A Japanese Dock This piece of debris happened to be part of a Japanese dock that was torn from its moorings during the tsunami and washed up on the shores of Oregon and brought back what researchers believe to be about 100 tons of sea life. Scientists from the Oregon State University state that the 66-foot-long deck has around 13 pounds of organisms per square foot. The dock did not show any signs of radiation from the Fukushima nuclear plant meltdown caused by the tsunami, but it did pose the threat of carrying invasive species. What that means is that these creatures that aren’t natives to the area could potentially throw the local ecosystems out of whack and cause irreparable damage to the native wildlife, such as the dread zebra mussel. 5. A Mystery Creature There have been some unusual things that have washed up on random shores after tsunamis, this being one of them. After the 2011 tsunami hit, this giant white mass had been washed out onto the shore of Japan and had many of the locals, along with everyone who watched this video on YouTube, wondering what it even was? Some thought it to be a brand new creature that had risen from the dark depths of the ocean floor while others speculated it was merely a large rock or boulder. Don’t worry, officials have concluded that this isn’t some new species that’s going to wipe us out. They simply stated that it’s most likely just a mass of whale blubber from the carcass of a dead whale that’s pretty much unrecognizable. 4. A Shipping Tote Back in November of 2014, this shipping tote had washed up near the shores of Seal Rock in Oregon. This 4-by-5 foot plastic shipping tote had been floating out at sea for the last 3 years since the tsunami struck and amassed around 200 blue mussels that were attached to it. Like the dock that was found in 2012, this tote was a potential host for carrying invasive species and scientist eventually determined it as a non-threat to the surrounding environment. Still, the amount of debris, the total estimated to be around 18.11 million tons with 70 percent of the debris sinking to the bottom of the ocean, is still rather high and is still washing up years after that tragic event took place. 3. Various Trash A barge from the fishing town of Ucluelet in British Columbia had carried in around “super sacks” of debris caused by the tsunami. Those sacks are designed to hold up to 1,000 pounds, so you can only imagine how heavy all that weight could possibly be. Ever since the tsunami struck, there have been volunteer pickups in the town where local and Japanese students have gotten involved. They’ve managed to collect all different sorts of garbage such as styrofoam, pieces of Japanese houses, and other debris. Though they’ve made progress, their results haven’t been achieved through smooth sailing. The coastline of Ucluelet is described as remote and rugged which made the cleanups very difficult and the fact that there was already debris unrelated to the tsunami already there makes for even more trash than expected. 2. An Entire Ship This yacht happened to be discovered in the Iwate Prefecture in Northeastern Japan in the town of Otsuchi nearly two months after the tsunami had hit. The ship weighs in at an incredible 200 tons and it’s a huge surprise that the two-story building that is supporting all that weight is still somehow managing to keep from collapsing. It’s hard to even process the amount of force needed to lift the ship. 1. A House As one of the most powerful and deadly disasters that can occur in nature, the tsunami is one that leaves devastation in its wake. Their sheer force can only be imagined by those who have never witnessed what it can be capable of at first hand and even then you can never come close to doing it justice. Take for example this house that was a part of the Fukushima debris. This was someone’s entire home where they built a life for themselves around it and in a matter of moments, it was swept off its foundation and carried out into the sea, along with what is estimated to be another 200,000 buildings.

An investigation into the nuclear industry and its actions in Africa, the film examines Africa’s power needs and the consequences of using nuclear energy. Africa’s development is being held back by its poor infrastructure and undersize power plants. Countries like Uganda can produce only a quarter of the energy needed, leading to daily power cuts with a disastrous impact on the economy. Companies like French nuclear giant Areva lobby aggressively for more power plants in Africa, but how safe are these new reactors? New nuclear power plants in Africa also mean more uranium mining, contaminating the environment and endangering the local population. First Released in 2013. Content Provided by DCD Rights.

The construction industry needs large quantities of gravel and crushed rock for concrete manufacturing. So far, recycled concrete has mostly been utilized as filling material or in substructures, but only hesitantly for structural engineering. The film shows how recycled concrete can be processed applying new methods to enable its use as an alternative building material even in structural engineering. The proportion of the building material able to be processed into high-quality products after a demolition can be considerably increased, which in turn reduces the environmental impact significantly.

Roger Moody is interviewed in this film about uranium mining ahead of a talk he gave in Stroud organised by Stroud District Green Party. Roger is Features Editor at Mines and Communities. More info at: http://www.minesandcommunities.org/ See also recent talk in Stroud about nuclear waste: http://stroudcommunity.tv/the-future-of-radioactive-waste-and-nuclear-safety-in-gloucestershire/ Amongst his publications are: "Rocks and Hard Places : The Globalization of Mining". The world of international mining is changing rapidly. Mineral consumption is outstripping the capabilities of both communities and fragile ecosystems to cope with bigger and bigger mines. Moody shows that mining can impact severely on local communities, ways of life and the environment. This key book concludes with urgent proposals to control multinationals in a sector that is at the core of resource exploitation. "The Gulliver File: Uranium Mining Industry [Hardcover]". This is a study of the world of mining - a book born from the experience of numerous environmental, anti-nuclear and indigenous groups, concerned about the negative impact of huge mineral mining projects. The book has profiles of more than 650 companies worldwide, including full details of their ultimate ownership and their subsidiaries and detailed information on hundreds of mining prospects - along with full accounts of resistance to them.

Physically removing the rock ore generally involves either open-pit mining or underground mining. Milling is the process that removes uranium from the ore, which is mostly obtained in open-pit and underground mines. Once at the mill, the ore is crushed and ground up, and treated with chemical solutions to dissolve the uranium, which is then recovered from the solution. Tailings are the wastes from the millings processes and are stored in mill tailings impoundments, a specially designed waste disposal facility. Since 1979, when uranium mine workers began being diagnosed with lung diseases, such as cancer, regulators have gradually tightened controls and mandated improved uranium mining practices. Recently, officials also have become concerned with the broader impacts of uranium mining on public health and the environment. Workers are directly exposed to the radiation hazards of uranium mines. Uranium mining also releases radon from the ground into the atmosphere. Mines and mining waste can release radionuclides, including radon, and other pollutants to streams, springs, and other bodies of water. Federal and state agencies have established pollutant discharge limits and drinking water standards, and continue to monitor these sites for public safety. Uranium mine waste from operations that closed before the mid-1970s are of particular concern. In many cases, these mines remain unclaimed and the waste is still piled near the mine. Weathering can lead to radioactive dust that is blown by the wind and the seepage of contaminants into the surface and groundwater. There are also cases of unclaimed uranium mine waste being used for house construction, which creates significant radon and radiation hazard for inhabitants. For more information on the hazards of uranium, go to USEPA website http://www.epa.gov/radtown/basic.html . This is clipped from the late 1970's BBC Production, Energy From The Crust, showing uranium mining activities and equipment and including footage from the following uranium mines: Schwartzwalder Mine, Near Boulder, Colorado King Solomon Mine near Uravan, Colorado and the Key Lake Mine in Saskatchewan, Canada.

We've got all this nuclear waste to dispose of, and we've got this superheated fusion ball in the sky. Couldn't we just blast our nuclear waste into the Sun and be done with it? Support us at: http://www.patreon.com/universetoday More stories at: http://www.universetoday.com/ Follow us on Twitter: @universetoday Like us on Facebook: https://www.facebook.com/universetoday Google+ - https://plus.google.com/+universetoday/ Instagram - http://instagram.com/universetoday Team: Fraser Cain - @fcain / [email protected] Karla Thompson - @karlaii Chad Weber - [email protected] When I look at the Sun, I don’t see a warm life-giving orb, nourishing all living creatures here on Earth. No, I see that fiery ball as a cosmic garbage compactor. A place I can dump all my household garbage, to make room for new impulse purchases. I mean, the Sun is right there, not doing anything right? It’s hotter than any garbage incinerator, and it’s the gravitational well at the heart of the Solar System. Get me a rocket, let’s blast that waste into oblivion. Okay, I suspect it’s going to get expensive, so let’s just start with the worst garbage on Earth: nuclear waste. You know, the byproduct of nuclear reactors that generate electricity for many parts of the world. This stuff is highly toxic and it’s going to be around for hundreds of thousands of years. It’s also pretty dense, maybe it does make sense to get this stuff off Earth and into the Sun? Let’s run the numbers. Nuclear waste, or radioactive waste, of course, is anything leftover material that still has radioactivity. For the most part, we get this as the leftover material from nuclear power reactors, but it’s also generated by hospitals, and nuclear weapons manufacturing. We’ve got leftover nuclear waste from uranium mining, radium processing, and various civil and military research projects. For example, when you mine uranium from the ground, you get leftover radium and radioactive rock, soil, and even the water. When you power a nuclear reactor, the spent fuel rods are still highly radioactive and dangerous. In the United States alone, there are hundreds of different sites which are heavily contaminated, over thousands of acres. According to the World Nuclear Association, OPEC nations generate 300 million tonnes of toxic waste every year. We’re talking about poisonous chemicals, medical waste, coal dust. Really anything that you don’t want anywhere near you, or inside you. Just to give you a sense of scale, that’s a cube of toxic poisons nearly a kilometer to a side, assuming the stuff is a little more dense than water. Out of this, only 97,000 tonnes of nuclear waste is generated across the planet every year. This is radioactive wastes of all types. That’s only .03% of all the toxic waste. But for the purpose of our calculations, I’m going to zero in on the most toxic, most radioactive material we’re dealing with: the high-level waste produced by nuclear reactors. Now we’re merely talking about 12,000 tonnes per year, or 12% of the nuclear waste showing up on our planet every year. Now, let’s look at launch costs. Most rocket companies are going to charge you $10,000 to $20,000 per kilogram to blast a payload into Low Earth Orbit. The best deal on the market right now is SpaceX at around $4,000 USD per kilogram. And if they get the Falcon Heavy flying this year, it could bring the price down to around $2,500 per kilogram. If all we wanted to do was blast all this waste into Low Earth Orbit, the calculations are pretty simple. 12,000 tonnes is 12 million kilograms. Multiply that by $2,500 per kilogram, and you get 30 billion dollars. You’re looking at 240 Falcon Heavy launches per year. Almost a launch every single day carrying a payload of high-level nuclear waste. Out of sight, out of mind. That’s a lot of money, but in theory, the world could afford it if they wanted to stop having wars, or something. If they wanted to blast off all the nuclear waste, it would be more like 250 billion. Again. An incomprehensible amount of money, but still within the realm of possibility, assuming that SpaceX gets the Falcon Heavy launching, lofting payloads of nuclear waste 50 tonnes at a time. But this is Low Earth Orbit, and we don’t want to go there. Anything in LEO still experiences friction from the Earth’s atmosphere, and eventually it’s going to return back to Earth. Imagine regular meteor showers of highly radioactive plutonium. That would be bad. It would be more safer to launch this stuff into Geostationary Orbit, where the television satellites are broadcasting from. Material in this orbit can be expected to hang around for a long long time. You’re looking at twice the price to blast off to GEO, so go ahead and double your costs to put that stuff safely out into space. 60 billion dollars for high-level waste. 500 billion for all the nuclear waste.

Interview with Gordon Edwards, President of the Canadian Coalition for Nuclear Responsibility (CCNR) at the Western Mining Action Network Conference, 2011. Dr. Edwards addresses the need to strengthen safety standards on uranium mining & radioactive elements in the tailings resulting from mining activities. Dr. Edwards recommends no new uranium mines be licensed until technologies exist allowing for the extraction of the long lived radio nuclides from the ore. Looking at the big picture, Dr. Edwards asserts that uranium mining shouldn't be allowed at all.

What happened at Three Mile Island, Chernobyl and Fukushima? What role did water coolant play in each one? Why do we use water as a coolant, given it has a liquid range of only 100 degrees Celsius? Today's reactors, which are cooled by pressurized water, were viewed as a stop-gap technology until "breeder reactors" could be commercially deployed. Breeder reactors convert fertile material (such as Thorium) into fissile material (such as Uranium-233). It is not practical to operate a breeder reactor with water coolant, so a new coolant must be chosen. We examine two coolant options (from a field of many): liquid salt, and liquid sodium. What advantages do each have over water? Is one safer than the other?

Superdump: Toxic waste seeps into the environment from South African mine dumps. December 2009 For downloads and more information visit: http://journeyman.tv/59894/documentary-films-archive/superdump.html After 120 years of gold mining, the land and water on Gautengs far West Rand are some of the most polluted in the country. The mine dumps that dot the area west of Johannesburg have been identified as public health risks. One of the biggest problems is uranium seeping into the watercourses, turning the sediment both poisonous and radioactive. Ecologists, the community and the mines all agree that the mine dumps must go. But no-one can agree what to do with them. This edition of Special Assignment takes a look at community resistance against two proposals to reprocess the mine dumps and relocate the resulting waste. Communities are clashing with the mines over two proposed superdumps mega-mine dumps proposed for Fochville and Randfontein. Should these communities suffer for the health of the entire region? And what impact will these superdumps have on food security?

In 2006 the Federal Government announced a plan to build a nuclear waste dump in the Northern Territory. While three sites were initially selected, the only site now under consideration is on Muckaty Station, 120km north of Tennant Creek. Traditional Owners, the NT Government, Unions NT, medical groups and the wider community oppose the proposed waste dump at Muckaty. The Federal Government is attempting to use heavy-handed and undemocratic legislation called the the National Radioactive Waste Management Billto build the dump.At the time of writing (November 2011) the Federal Government has been unsuccessful in attempts to get this contested bill passed by the Senate. What kind of radioactive waste is it? The waste that the Federal Government proposes to dump on the Territory includes: Low-level and short-lived intermediate- level radioactive waste destined for shallow burial. Long-lived intermediate level waste which will be stored above ground as an 'interim' measure until some future government establishes a deep underground geological disposal facility. The Government has made no progress finding a site for disposal of the long-lived intermediate-level waste so 'interim' storage in the NT would last for decades and possibly centuries. Where is the waste coming from and how much is there? Measured by radioactivity, almost all the waste comes from the Lucas Heights nuclear reactor site south of Sydney as spent fuel rods. These spent fuel rods are taken overseas to be re-processed and are on contract to be bought back to Australia in 2014. Measured by volume, Lucas Heights accounts for almost half the waste, lightly contaminated soil stored at Woomera in SA accounts for about half, and very small volumes are stored at various scientific, medical and defence sites around Australia. How should Australia's radioactive waste management be managed? All options for radioactive waste management need to be considered − not just 'remote' repositories. This includes the option of ongoing storage at the Lucas Heights nuclear reactor site on the outskirts of Sydney, operated by the Australian Nuclear Science and Technology Organisation (ANSTO). All relevant organisations − including ANSTO, the regulator ARPANSA, the Australian Nuclear Association, and even Federal Resource Minister Martin Ferguson's own department − have acknowledged that ongoing storage at Lucas Heights is a viable option. A site selection process is required, it ought to be based on scientific and environmental criteria, as well as on the principles of community consent. When the federal Bureau of Resource Sciences conducted a preliminary site selection study in the 1990s, based on environmental and scientific criteria, the Muckaty area did not even make the short-list as a ''suitable'' site for a nuclear dump. Yet Muckaty is the only site now under consideration. Nuclear Medicine Many countries have good nuclear medicine services but do not have a nuclear reactor or a nuclear waste dump. As the Medical Association for the Prevention of War says, the government has been 'peddling a lie' by linking the proposed NT dump to nuclear medicine.

On March 11th 2011 the world watched in horror as news emerged from Japan of the devastating earthquake, tsunami and subsequent nuclear emergency at Fukushima. Two yaers later over 150,000 people cannot return to their homes and farms because of radiation and the long-term contamination footprint is not yet known. The Mirarr people of Kakadu - from whose land uranium is mined and shipped to many countries including Japan - were especially saddened to learn of the nuclear disaster and the ongoing impact on so many people's lives. The Ranger uranium mine was imposed on the Mirarr thirty years ago and Mirarr Senior Traditional Owner Yvonne Margarula wrote to UN Secretary General Ban Ki-Moon, stating her people's sadness at the events at Fukushima, reiterating Mirarr opposition to the Jabiluka development and urging the Secretary-General to include the viewpoint of Indigenous people (from whose land the majority of mined uranium is sourced) in his deliberations on the nuclear industry. It has since been confirmed that Australian uranium was present in the stricken reactors. As we reflect on the impact of one of the world's worst ever nuclear disasters let us never forget the ongoing negative consequences of the nuclear industry.

Uranium-233 is fissile, and can fission into energy and fission products.

The Environmental Protection Agency has said it has no system for monitoring hundreds of thousands of abandoned mines that pock the American landscape or knowing which one could be the source of the next big toxic spill. a spokesman for the federal agency told the Guardian the EPA doesn't keep records of the number of mines or tailings dams, structures that store mine waste, in the US. In the western US, the EPA estimates there may be 161,000 abandoned “hard rock” mines, where metals such as gold, silver and copper were once dug. Over decades, old mines fill up with rainwater.

Curium is a hard metal having an atomic number of 96 and symbol Cm. This metal is artificially produced in the nuclear reactors. It is electro-positive, radioactive and also a chemically active substance, which is not obtained naturally. This metal possesses some magnetic properties. As the temperature increases, the resistivity of this metal also increases. In the year 1944, Glenn Seaborg, Albert Ghiorso, and James discovered this metal and named after Marie Curie and Pierre Curie. The element is believed to glow red in the dark due to its radioactive nature. Atomic number 96 Atomic mass 247 Melting point 1345°C, 2453°F, 1618 K Boiling point 3110 °C, 5630°F, 3383 K Group Actinides; Period 7; Block f Curium has 15 isotopes out of which the most stable one is Curium-247 with a half-life of about 16 million years that undergoes alpha-decay to form plutonium-243. As it is not found naturally in the earth’s crust, the radioactive element has only been used in basic research studies due to its limited laboratory production. Also, it does not react with other compounds. However, curium-244 can be applicable as a power source for operating radioisotope thermoelectric generators used in spacecraft. Curium-244 has been used in Alpha Proton X-ray Spectrometer to detect the presence of chemical elements in the atmosphere and rock surface compounds of Mars. Curium is a hazardous metal, which causes some health disorders when inhaled. It damages the liver and also causes breathing and gastrointestinal problems when ingested. The radiation, which is emitted by curium are likely to cause the destruction of the red blood cells. Improper disposal of curium leads to various environmental issues. Curium is found in nature in the form of its oxides. The radiation generated from this metal has many natural impacts. Curium is an insoluble chemical, which fixes to the soil particles.

http://cuttlefishcountry.com BHP Billiton's Olympic Dam mine is massive and destined to become the biggest open cut mine in the world. Naturally, with massive mines come massive impacts... environmentally, socially and economically. Widely published environmental engineer Dr Gavin Mudd (Monash University) gives this presentation on the impact the mining operation will have from the desert to the sea, and beyond through the export of dangerous radioactive materials. Tailings dams will leak radioactive waste into the earth in the South Australian desert, the water drawn from the Great Artesian Basin will continue to dry natural mound springs, threaten pastoral and agricultural bores and endanger arid zone ecology and indigenous sacred sites. Dr Gavin Mudd delivered this presentation in Adelaide, South Australia on October 9th, 2011... the day before the mega-mine project received environmental approval from both State and Federal Governments.

Changing another world to support Earth life is called terraforming. But maybe it's a better idea to just change Earth life to live on other worlds. Support us at: http://www.patreon.com/universetoday More stories at: http://www.universetoday.com/ Follow us on Twitter: @universetoday Follow us on Tumblr: http://universetoday.tumblr.com/ Like us on Facebook: https://www.facebook.com/universetoday Google+ - https://plus.google.com/+universetoday/ Instagram - http://instagram.com/universetoday Team: Fraser Cain - @fcain / [email protected] Karla Thompson - @karlaii Chad Weber - [email protected] As soon as people learn how inhospitable Mars, Venus, and really the entire Solar System are, they want to know how we can fix it. There’s a word for fixing a planet to make it more like Earth: terraforming. If you want to fix Mars, all you have to do is thicken and warm up its atmosphere to the point that Earth life could survive. You’d need to do the opposite with Venus, cooling it down and reducing the atmospheric pressure. But it’s hard to wrap your brain around the scale it would take to do such a thing. We’re talking about an incomprehensible amount of atmosphere to try and modify. The atmospheric pressure on the surface of Venus is 90 times the pressure of Earth. It’s carbon dioxide, so you need some chemical, like magnesium or calcium to lock it away. If you can mine, for example, 4 times the mass of asteroid Vesta, it should be possible. No, from our perspective, that’s practically impossible. In fact, it’s kind of ironic, when you consider the fact that we’re making our own planet less habitable to human civilization every day. There’s another path to making another world habitable, however, and that’s changing life itself to be more adaptable to surviving on another world. Instead of terraforming a planet, what if we terraformed ourselves? Actually, that’s a really bad term. We’d really be changing ourselves to be better adapted to living on Mars. So we’d be Marsiforming ourselves? Venisfying ourselves? Okay, I’ll need to work on the terminology. But you get the gist. Life, of course, has been evolving and adapting on Earth for at least 4.1 billion years. Pretty much as soon as life could arise on Earth, it did. And those early lifeforms went on to modify and change, adapting to every environment on our planet, from the deepest oceans, to the mountains. From the deserts to the icy tundra. But in the last few thousand years, we’ve taken a driving role in the evolution of life for the domesticated plants and animals we eat and care for. Your pet dog looks vastly different from the wolf ancestor it evolved from. We’ve increased the yield of corn and wheat, adapted fruit and vegetables, and turned chickens into flightless mobile breast meat. And in the last few decades, we’ve gained the most powerful new tools for adapting life to our needs: genetic modification. Instead of waiting for evolution and selective breeding to get the results we need, we can rewrite the genetic code of lifeforms, borrowing beneficial traits from life over here, and jamming it into the code of life over there. What doesn’t get cooler when it glows in the dark? Nothing, that’s what. Can we adapt Earth life to live on Mars? It turns out, our toughest life isn’t that far off. During the American Society for Microbiology meeting in 2015, researchers presented how well tough bacteria would be able to handle the conditions on Mars. They found that 4 species of methanogens might actually be able to survive below the surface, consuming hydrogen and carbon dioxide and releasing methane. In other words, under the right conditions, there are forms of Earth life that can survive on Mars right now. In fact, as we continue to explore Mars, and learn that it’s wetter than we ever thought, we risk infecting the planet with our own microbial life accidentally. But when we imagine life on Mars, we’re not thinking about a few hardy methanogens, struggling for life beneath the briny regolith. No, we imagine plants, trees, and little animals scurrying about. Do we have anything close there that we could adapt? It turns out there are strains of lichen, the symbiosis of fungi and algae that could stand a chance. You’ve probably seen lichen on rocks and other places that suck for any other lifeform. But according to Jean-Pierre de Vera, with the German Aerospace Center’s Institute of Planetary Research in Berlin, Germany, there are Earth-based lichen which are tough enough. They put lichen into a test environment that simulated the surface of Mars: low atmospheric pressure, carbon dioxide atmosphere, freezing cold temperatures and high radiation. The only things they couldn’t simulate were galactic radiation and low gravity. In the harshest conditions, the lichen was barely able to hang on and survive, but in milder Mars conditions, protected within rock cracks, the lichen continued to carry out its regular photosynthesis.

Kirk Sorensen's Tech Talk, delivered at Google on July 20, 2009. Successfully developing a liquid-fluoride thorium reactor (LFTR) would essentially solve our planets energy problems for thousands of years, because it would allow us to fully utilize the energy in natural thorium, which makes up 0.0012% of the Earths crust. Most of the research and development work for this technology was done by Oak Ridge National Labs back in the 50s and 60s. They were working to a different set of overall objectives, nevertheless, there are many lessons to be gleaned from their work that can help us to avoid pitfalls and develop LFTR into a high-performance, high-reliability power supply.

A demonstration of activity in a hand sample of Orphan Mine uranium ore. Orphan uranium ore samples are hard to find now, due to the fact that the mine is on Grand Canyon National Park and is off limits for collections. But there are some Orphan waste piles outside park boundaries, and samples such as this can be collected from the surface. No digging allowed though.

Thorium is an abundant material currently disposed of as waste. It is found in coal ash piles and mine tailings. A single Rare Earths mine could produce enough Thorium byproduct to power the entire planet. To do so requires a very different nuclear reactor than the kinds we use today. Not one that uses solid fuel rods, but a reactor in which the fuel is kept in a liquid state. Not one that uses pressurized water as a coolant, but a reactor that uses extremely stable molten salts. The full description of one such reactor is: 2-Fluid, Thermal-Spectrum, Molten-Salt Breeder Reactor equipped with a chemical fuel salt treatment module. Such a reactor was conceived of decades ago, as documented in the book "Fluid Fuel Reactors" . Or, simply "LFTR" (Liquid Fluoride Thorium Reactor) as proposed by Flibe Energy's Kirk Sorensen... a modern redesign of the 2-Fluid, thermal-spectrum, MSBR concept. http://Flibe-Energy.com/ Since 2011 (the year Flibe Energy was founded), legislators asking questions about Thorium have had their queries answered as if such a reactor design did not exist. NNL [UK] and OECD [NEA] reports on the Thorium Fuel Cycle did not explore the implications of this reactor, and dismiss thorium based on challenges and mediocre performance found in other reactor designs. For example, other options include a "Fast-Spectrum Molten-Salt Reactor". Worth pursuing, certainly, but requires more fissile inventory than LFTR... approximately 5x as much. (Fissile inventory is specifically mentioned as a concern by OECD's thorium report.) And assuming the challenges of a fast-spectrum MSR can be met... both natural Uranium and natural Thorium can both be fully consumed as fuel in a fast-spectrum reactor. That is where Thorium is dismissed as only "4x as common as Uranium" (fast-spectrum usage) rather than "400x as common as U-235" (thermal-spectrum usage). Thorium's advantages: both thermal-spectrum breeding and unique chemical properties, are taken full advantage of only by LFTR style reactors. When evaluated in any other reactor, depending on that reactor, Uranium can be as attractive, more attractive, or Uranium can be the only viable option. For example: Shippingport. Cited as an example of a "Thorium Reactor" by Dr. Lyons, it was NEVER intended to be economical, and features no advantages of LFTR. It was a solid-fuel reactor, and so operated at low-temperature, had no on-line chemical reprocessing, used high-pressure water coolant, used fuel as inefficiently as every other solid-fuel reactor, and had to be shut down every time it was refueled. 2 of its 3 fuel loads were Enriched Uranium. It was -a- Reactor capable of consuming Thorium and demonstrated only that it was possible... it was not -THE- Thorium Reactor.

Google Tech Talks November 18, 2008 ABSTRACT Electrical power is, and will increasingly become, the desired form of energy for its convenience, safety, flexibility and applicability. Even future transportation embraces electric cars, trains, and chemical fuel production (jet fuel, hydrogen, etc.) based upon an abundant electrical supply. Although existing energy sources can and should be expanded where practical, no one source has shown to be practical to rapidly fulfill the world's energy requirements effectively. Presently there is an existing source of energy ideally suited to electrical energy production that is not being exploited anywhere in the world today, although its existence and practicality has been know since the earliest days of nuclear science. Thorium is the third source of fission energy and the LFTR is the idealized mechanism to turn this resource into electrical energy. Enough safe, clean energy, globally sustainable for 1000's of years at US standards. This talk is aimed at explaining this thorium energy resource from fundamental physics to today's practical applications. The presentation is sufficient for the non-scientist to grasp the whole subject, but will be intriguing to even classically trained nuclear engineers. By providing the historical context in which the technology was discovered and later developed into a power reactor, the story of thorium's disappearance as an energy source is revealed. But times have changed, and today, thorium energy can be safely exploited in a completely new form of nuclear reactor. The LFTR is unique, having a hot liquid core thus eliminating fuel fabrication costs and the need for a large reactor. It cannot have a nuclear meltdown and is so safe that typical control rods are not required at all. This design topples all the conventional arguments against conventional energy sources in such areas as: * Waste Production * Safety * Proliferation * Capital Costs and Location * Environmental Impact * Social Acceptance * Flexibility * Grid Infrastructure * Efficiency Should America take this step toward a New Era in Nuclear Energy Production? Hear the case for "The Electricity Rock" and then decide. Speaker: Dr. Joe Bonometti Dr. Bonometti has extensive engineering experience in the government, within industry, and in academia over a 25-year career. Recently completing an assignment as the NASA Chair Professor at the Naval Post graduate School, he supported a ship design study that utilized advanced nuclear power derived from thorium. Working at NASA for ten years as a technology manager, lead systems engineer, nuclear specialist, and propulsion researcher, he lead several NASA tiger teams in evaluating the Nuclear System Initiatives fission demonstration vehicle and missions. He managed the Emerging Propulsion Technology Area for in-space systems, the Marshall Air Launch team, as well as a variety of other power and propulsion assignments and is now the Lead Systems Engineer for the Ares I-Y flight. After earning a Doctorate degree in Mechanical Engineering from University of Alabama in Huntsville, he spent several years as a Research Scientist & Senior Research Engineer at the UAH Propulsion Research Center where he served as a Principal Investigator and manager for the Solar Thermal Laboratory. He has worked as a Senior Mechanical Designer at Pratt & Whitney supporting aircraft engine manufacturing and at the Lawrence Livermore National Laboratory within the laser fusion program. A graduate from the United States Military Academy, at West Point, where he studied nuclear physics and engineering, Dr. Bonometti served as an officer in the United States Army Corps of Engineers; both in combat and district engineering management assignments. He is a Registered Professional Engineer in the State of Virginia, and has authored numerous aerospace technical publications, particularly propulsion and space systems technologies.

Coal is the most abundant fossil fuel and the least expensive one used to generate electricity in the US. It's also the source of many local problems, including those caused by strip mining and mountaintop removal, as well as disposal of toxic coal ash. But the biggest threat of all may be to the entire planet: burning coal releases large amounts of carbon dioxide, or CO2 — and carbon dioxide is a major contributor to climate change. Scientists say if the world continues emitting carbon dioxide following current trends, the average global temperature could rise by 7 degrees Fahrenheit or more by the year 2100, and by 9 degrees or more in the U.S. The oceans, expanding as they warm and flooded with melt-water from glaciers and ice sheets on land, could rise between two and five feet. In Georgia, a state that gets 60 percent of its electricity from coal (the national average is 50 percent), residents are already worried about the effects on their state's economy and ecology. As the temperature rises, the Live Oak — the state tree — could find it hard to thrive. Coastal cities like Savannah, meanwhile, will be under increasing threat from the rising sea. Like others across the country, Georgians are connecting the dots between how they get their electricity and what the future holds for their lives. As a result, they're trying to figure out how to cut down on the CO2 emitted by burning coal. One answer might be to reduce the amount of coal used — but coal is abundant and inexpensive, and therefore hard to give up. Yet it's also possible to reduce the amount of CO2 that comes from a coal-fired power plant. That's the idea behind "clean coal" or, to use the more technical term, carbon capture and sequestration (CCS). CCS technology could capture as much as 90% of the carbon dioxide emitted from coal power plants and pipe it deep underground, into porous formations of rock and sand that can absorb the CO2 and prevent its escape to the atmosphere. CCS technology appears to be viable, but implementing it at large scales is still at least a decade away. It also will require billions of dollars in investment, and some states, like Georgia, are less geologically suitable for storing carbon dioxide than others. CCS will make electricity from coal more expensive. And some opponents worry about whether any underground location can truly contain the CO2. The wider debate about clean coal and CCS is being played out on television, through a multimillion-dollar advertising war. Opponents say coal is a "dirty rock" that can't be wiped clean with an advertising campaign. They insist that even if the CO2 problem is fixed, mining, ash disposal and combustion will keep coal from being truly clean. The other side emphasizes the fact that coal is inexpensive, that the U.S. has domestic reserves that could last two hundred years or more, and that using coal is a prime way to help the U.S. remain competitive with fast-growing economies like China and India — both of which are major coal users. Even if CCS ultimately proves to be successful on a wide scale, experts say that there are steps people can immediately pursue to get a head start on reducing carbon dioxide emissions. "Efficiency is the first fuel that we should be going to," says Stephen Smith, Executive Director for the Southern Alliance for Clean Energy. Others point out that reducing CO2 emissions to the degree needed to avoid major climate change will require not only efficiency improvements, but also a portfolio of options. CCS, they say, could be one such option. Toward that end, the federal government is currently directing some stimulus funding to help demonstrate CCS technologies. Meanwhile, Congress is debating legislation to regulate carbon-dioxide emissions. If such legislation is approved, that could ultimately provide the necessary incentive for coal-burning companies to invest billions of dollars in CCS — the amount needed to make CCS a reality.
