適用范圍：This International Standard provides the basis for calculating the decay heat power of non-recycled nuclear fuel of light water reactors. For this purpose the following components are considered:— the contribution of the fission products from nuclear fission;— the contribution of the actinides;— the contribution of isotopes resuiting from neutron capture in fission products.This International Standard applies to light water reactors (pressurized water and boiling water reactors) loaded with a nuclear fuel mixture consisting of 235 U and 238 U. Its application to recycled nuclear fuel is not permissible.The calculation procedures apply to decay heat periods of 0 and 109 s.
