Integral Fast Reactor
The integral fast reactor (IFR), originally the advanced liquid-metal reactor (ALMR), is a design for a nuclear reactor using fast neutrons and no neutron moderator (a "fast" reactor). IFRs can breed more fuel and are distinguished by a nuclear fuel cycle that uses reprocessing via electrorefining at the reactor site. The IFR was a sodium-cooled fast reactor (SFR) is its closest surviving fast breeder reactor, a type of Generation IV reactor. The U.S. Department of Energy (DOE) began designing an IFR in 1984 and built a prototype, the Experimental Breeder Reactor II. On April 3, 1986, two tests demonstrated the safety of the IFR concept. These tests simulated accidents involving loss of coolant flow. Even with its normal shutdown devices disabled, the reactor shut itself down safely without overheating anywhere in the system. The IFR project was canceled by the US Congress in 1994, three years before completion. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TerraPower
TerraPower is an American nuclear reactor design and development engineering company headquartered in Bellevue, Washington. TerraPower is developing a class of nuclear fast reactors termed traveling wave reactors (TWR). Description TWR places a small core of the enriched fuel in the center of a much larger mass of non-fissile material, in this case depleted uranium. Neutrons from the fission in the core "breeds" new fissile material in the surrounding mass, producing Plutonium-239. Over time, enough fuel is bred in the area surrounding the core that it can undergo fission, enabling a steady-state reactor composition to be approximated by moving outer fuel rods towards the core as original core fuel rods are moved to the periphery. Natrium uses liquid sodium as a coolant, reducing the cost of using an ambient pressure primary loop. It then transfers that heat to molten salt, which can be stored in tanks and used to generate steam on demand, enabling the reactor to run contin ...

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into 3 categories: low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity; intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding; and high-level waste (HLW), which is highly radioactive and hot due to decay heat, thus requiring cooling and shielding. Spent nuclear fuel can be processed in nuclear reprocessing plants. One third of the total amount have already been reprocessed. With nuclear reprocessing 96% of the spent fue ...

Clinch River Breeder Reactor Project
The Clinch River Breeder Reactor Project was a nuclear reactor project that aimed to build the USA's first large-scale demonstration breeder reactor plant. It was led by the U.S. Atomic Energy Commission (and a successor agency, the U.S. Energy Research and Development Administration (ERDA), and subsequently the U.S. Department of Energy). The project was opposed by President Carter. Peter A. BradfordDelivering the nuclear promise ''Bulletin of the Atomic Scientists'', June 2016. The project was intended as a prototype and demonstration for building a class of such reactors, called Liquid Metal Fast Breeder Reactors (LMFBR), in the United States. The project was first authorized in 1970. After initial appropriations were provided in 1972, work continued until the U.S. Congress terminated funding on October 26, 1983. The project was seen to be "unnecessary and wasteful". Location The site for the Clinch River Breeder Reactor was a land parcel owned by the TVA adjacent to the Cl ...

Secretary Of Energy
The United States secretary of energy is the head of the United States Department of Energy, a member of the Cabinet of the United States and fifteenth in the presidential line of succession. The position was created on October 1, 1977, when President Jimmy Carter signed the Department of Energy Organization Act, establishing the department. Originally, the secretary and the department focused on energy production and regulation. Over time, the emphasis shifted to developing technology for more efficient energy sources and energy education. After the Cold War, the department's attention also turned to radioactive waste disposal and environmental quality maintenance. Former Secretary of Defense James Schlesinger was the first secretary of energy. As a Republican nominated by Democratic President Jimmy Carter, Schlesinger’s appointment remains the only instance of a president choosing a member of another political party for the position. Schlesinger is also the only secretary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of Phenomenon, phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of Physics#Research fields, research fields, spanning all length scales: from atom, sub-atomic and particle physics, through biological physics, to physical cosmology, cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: Experimental physics, experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and Theoretical physics, theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena.

Idaho National Laboratory
Idaho National Laboratory (INL) is one of the national laboratories of the United States Department of Energy and is managed by the Battelle Energy Alliance. Historically, the lab has been involved with nuclear research, although the laboratory does other research as well. Much of current knowledge about how nuclear reactors behave and misbehave was discovered at what is now Idaho National Laboratory. John Grossenbacher, former INL director, said, "The history of nuclear energy for peaceful application has principally been written in Idaho". The present facility resulted from the 2005 merger of two neighboring laboratories, the National Engineering and Environmental Laboratory, and the Idaho site of the western branch of Argonne National Laboratory (Argonne-West). Various organizations have built more than 50 reactors at what is commonly called "the Site", including the ones that gave the world its first usable amount of electricity from nuclear power and the power plant fo ...
