However, some of those parts usually contain small amounts of radioactive elements, like thorium and uranium, so you can see how people can be antsy about radioactive sludge being released to the environment, even with all the precautions taken by Lynas. It was a long-standing issue that had been ...

Tomsk Polytechnic University scientists are working on a new technology that will pave way for use of weapons-grade plutonium to be used in thorium reactors. Scientists say that their high-temperature gas-cool low-power reactors with thorium fuel can be used to generate power and thermal energy.
thorium reactors are used in areas where there are no large water bodies and rivers, which are needed for classical reactors. They can also be used in arid areas as in remote areas of Siberia and the Arctic. Associate Professor Sergey Bedenko from the school of Nuclear science & engineering says, "As ...
A third-party medical company, whose name has not been disclosed, will extract thorium from the uranium inventory and use it to pay Isotek, Environmental Management's nuclear cleanup contractor. The contract modification was approved after its evaluation as part of Environmental Management's 45-day ...
A first order objective is reported to be the kickoff of design and development of a first of a kind thorium molten salt reactor in 2020 in the city of Wuwei in Gansu Province. Commercial development is targeted for the early 2030s. The program is called the thorium-Breeding Molten Salt Reactor (TMSR).

It is a naturally occurring isotope produced by the radioactive decay of thorium in sediments. But unlike thorium, it dissolves into water, where scientists can track the sources, amounts, rates, and direction of its flow, said Kipp, who is lead author of the study and a graduate student in the MIT-WHOI Joint ...
thorium a lustrous radioactive element with the highest temperature of 3,000 degrees has been acknowledged as an interesting resource on the planet. The global thorium market was boosted with the rising applications in the production of nuclear fuel. Several demonstrations have been carried out to ...
Nuclear and radiation experts yesterday had cautioned the public over potential hazards posed by naturally-occurring radioactive elements in construction materials. Commonly found in materials naturally sourced from earth, uranium and thorium are Naturally Occurring Radioactive Materials (NORM) often ...
The two elements (uranium and thorium) undergo a natural decaying process to form other harmful elements and emit several types of radiation, particularly alpha, beta or gamma rays. Atomic Energy Licensing Board (AELB) director-general Hamrah Mohd Ali, in an exclusive interview with the New straits ...

It is considered a world leader in thorium-based technology. To move to thorium, India has a three-stage nuclear program. First, it will use normal uranium in Pressurised Heavy Water Reactors. Then it will use plutonium obtained from these in Fast Breeder Reactors. These Fast Breeder Reactors will create ...
Stop thorium in een kerncentrale in plaats van uranium, en je krijgt CO2-vrije energie, zonder gevaarlijk kernafval en kans op ongelukken. ... thorium heet het, vernoemd naar de Noorse god van de donder, en het is overvloedig op de aardkorst beschikbaar, ook in het stadspark bij jou om de hoek.
"King Abdullah University of science and technology together with Chinese scientists have begun the exploration and the valuation of uranium and thorium deposits in the country's northern region of Ha'il," the official said. According to the official, the project is being carried out at the order of Crown Prince ...
The Port Hope Area Initiative is mandated to remove low-level radioactive waste -- primarily radium-226, uranium, arsenic and thorium-230 and does not remove the other waste material. However, Craig Hebert, PHAI general manager, said under the legal agreement with Canadian Nuclear Laboratories ...
Smith says for the West Lake landfill, the "clean-up level" for thorium 232 is 7.9 picocuries per gram, while at the Cass Avenue site, thorium 232 was found at levels as high as 14.3. Smith has sent a letter to the EPA and Army Corps of Engineers calling for more testing. Smith's letter also requests testing ...

The most common of these chains are the thorium, radium and actinium series, all ending with stable, unreactive and frankly boring lead. These decay chains occur constantly in Earth's crust, continuously replenishing reservoirs of lead. This helps explains why it is so much more abundant than gold.
Die belangstelling voor thorium heeft een even banale als dwingende achtergrond: de 37 kerncentrales die China nu in gebruik heeft, en de 20 die nu in aanbouw zijn, hebben allemaal uranium nodig. Het land beschikt echter nauwelijks over die grondstof. thorium is daarentegen wel in zeer grote ...
The chinese reactors could use thorium. China has some of the world's largest reserves of the thorium metal.

Yan Long, a researcher involved in the Chinese project at the Shanghai Institute of Applied physics, said the Gansu facility might eventually help China develop a thorium-powered warship or aircraft. He said it was now possible to build a very small molten salt reactor and that after years of research and ...
The nature of energy supply is changing and changing fast. nuclear technology must also evolve if it wishes to survive, or so the argument goes. However, this change presents its own set of risks which are best addressed by carefully selecting priorities. As we race to introduce new reactor designs ...
thorium has long held promise for "safer" nuclear power. A slightly radioactive element, it transforms into fissionable U-233 when hit by high-energy neutrons. But after use, U-233 creates fewer long-lived radioactive waste products than the conventional U-235 now used in nuclear power plants.
It's just one polonium-, bismuth-, thorium-, and radium-tainted reminder of the way the uranium industry, enabled by the federal government, ravaged the West and its people for decades. In 1949, the vanadium corporation of America built a small mill at the confluence of White Canyon and the Colorado ...
... deranged General Jack D. Ripper--and the protocol will not permit the president of the United States to recall the plane. When the bomb explodes, it will trigger a Doomsday Machine installed by the Soviet military, dispersing a radioactive cloud of deadly Cobalt-thorium G all across the earth and wiping ...
