Description
JENDL-5 has been utilized in many fields including nuclear engineering since its release, and results of validation works have been also reported. Generally, validation of the evaluated nuclear data libraries is carried out using the measurement data on the integral parameters obtained at nuclear facilities. In the field of nuclear engineering, the radioactive decay data play important roles mainly in reactor kinetics problems and nuclear fuel burnup (or depletion) problems. Some examples of validation works for the JENDL-5 decay data using the relevant benchmark problems are presented. The integral data, which are sensitive to the decay data, are generally sensitive to other nuclear data also, and this is discussed using some examples of the post-irradiation examination data. Finally, the explicit fission model, which uses the decay data of fission products directly, is also briefly explained as an example of application of the decay data to the nuclear engineering problems.
