Nuclear Reactor Fuel Safety: The Waiting Gain

, former director, Nuclear Safety Project

Nuclear power reactors spilt atoms to release energy used to generate electricity. Many of the byproducts formed when atoms split are unstable (radioactive) and release particles or gamma rays in search of stability. These radioactive emissions produce energy. Whether in the core of an operating reactor, in the core of a shutdown reactor, in the spent fuel pool after discharge from a reactor core, or in dry storage after offloading from a spent fuel pool, the energy released from nuclear reactor fuel must be removed before it damages the fuel from overheating. This commentary describes the energy levels associated with nuclear fuel in various locations at various times to illustrate the factors that affect the associated hazard levels. Read more >
