Understanding Decay Heat

Decay heat removal is the key factor in many nuclear accident scenarios, and so reactor designers and operators work hard to ensure cooling is robust. Figure 1. Relative power of a nuclear reactor before and after shutdown.Details

51884 Proposed Rules Federal Register

industry consensus standard on decay heat rates, ANS/ANSI––1994, a standard developed by the American Nuclear Society (ANS) and approved by the American National Standards Institute (ANSI). The petitioner also asks that licensees be given the option to adopt, without further rulemaking,Details

Decay heat Wikipedia

Decay heat is the heat released as a result of radioactive decay. This heat is produced as an effect of radiation on materials: the energy of the alpha, beta or gamma radiation is converted into the thermal movement of atoms.Details

Decay Heat Federal Emergency Management Agency

Decay of fission products also produces heat, referred to as decay heat, that must be removed even after the reactor is shut down. If the decay heat is not removed, it will result in failures of the barriers designed to contain the fission products and possibly a radioactive release from the plant.Details

What is Decay Heat? – MIT NSE Nuclear Information Hub

The decay radiation then deposits most of its energy in the fuel, and this is what is referred to as decay heat. As these radioactive isotopes continue to decay, more and more of them reach a stable state and stop emitting radiation, and thus no longer contribute to the decay heat.Details
