DINGUS: Program for Calculating the Decay Heat of Nuclear Fuels in High-Temperature Reactors with Spherical Fuel Elements

[Automatically extracted and translated] The DINGUS program is used to calculate the decay heat of nuclear fuels in high-temperature reactors with spherical fuel elements. The user can decide whether to include the contributions of actinides and neutron capture reactions and whether the calculations are carried out for the reactor core or for a discharged fuel element. The calculations are based on the DIN 25 485 standard, which is referenced for further explanation of the calculation methods. The DIKOEF program is used for the one-time storage of the values of the total thermal energy release from a nuclear fission of the individual fission products and their standard deviation, as well as the tabular values for the factors A(t) and H(t) for calculating the contributions of actinides and neutron capture reactions and the values of the coefficients a, ß, and the exponents X. These values are stored in a permanent dataset and read by the DINGUS program. The following provides only an input description, a variable list, and a record of the program structure of DINGUS. The program listing and the example run of the DIN 25 485 standard are attached.
