NUCLIDE KINETICS SOLVING PROBLEMS WITH EXTENDED SINGLE-GROUP CROSS SECTIONS LIBRARIES

Preprint IBRAE-2023-01

E.F. Mitenkova, N.V. Novikov, E.V. Solovjeva

The ambiguous compilation of extended libraries with high-threshold reactions can result in noticeable nuclide composition differences  in accurate calculations of nuclide kinetics  problems. The importance of high-threshold reactions inclusion in libraries is confirmed by methodical calculations using MZK program. The extended libraries effect on irradiated steel ChS-68 and EK-181 composition is analyzed.
