While the individual plant examination?takes into account events that could challenge the design from things that could go awry internally (in the sense that equipment might fail because components do not work as expected), the individual plant examination for external events?considers challenges such as earthquakes, internal fires, and high winds.
Industry:Energy
One of the two primary recovery methods that are currently used to extract uranium from ore bodies where they are normally found underground (in other words, in situ), without physical excavation. Also known as “solution mining” or in situ leaching.
Industry:Energy
A complex designed and constructed for the interim storage of spent nuclear fuel; solid, reactor-related, greater than Class C waste; and other associated radioactive materials. A spent fuel storage facility may be considered independent, even if it is located on the site of another NRC-licensed facility. For further information, see Storage of Spent Nuclear Fuel and Locations of Independent Spent Fuel Storage Installations.
Industry:Energy
Activities that address the short-term, direct effects of a natural or human-caused event and require an emergency response to protect life or property.
Industry:Energy
From the Latin for "in glass," isolated from the living organism and artificially maintained, as in a test tube.
Industry:Energy
A process using a solution called lixiviant to extract uranium from underground ore bodies in place (in other words, in situ). Lixiviant, which typically contains an oxidant such as oxygen and/or hydrogen peroxide mixed with sodium carbonate or carbon dioxide, is injected through wells into the ore body in a confined aquifer to dissolve the uranium. This solution is then pumped via other wells to the surface for processing.
Industry:Energy
The region in a radiation/contamination area where the level of radiation/contamination is significantly greater than in neighboring regions in the area.
Industry:Energy
The processing of reactor fuel to separate the unused fissionable material from waste material. Reprocessing extracts isotopes from spent nuclear fuel so they can be used again as reactor fuel. Commercial reprocessing is not practiced in the U. S. , although it has been practiced in the past. However, the U. S. Department of Defense oversees reprocessing programs at DOE facilities such as in Hanford, WA, and Savannah River, SC. These wastes as well as those wastes at a formerly operating commercial reprocessing facility at West Valley, NY, are not regulated by the NRC.
