Research on Nuclear Reaction Network Equation for Fission Product Nuclides in Strong Neutron Field

Considering the neutron reaction, a computer code system FIRENEQ and its associated data libraries FPYDDL(fission product yield and decay data library) and FPNCDL (fission product neutron cross-section data library) were developed. The program was tested and the results are correct and reliable. With this system, the number of the fission product nuclides at different time with different neutron field intensities and neutron energy spectra can be calculated.
