Multi-group library generation for the study of nuclide transmutation in High Flux Engineering Test Reactor
Transmutation of the nuclear waste which contains MA and FP is important and necessary. Because the major MA and FPs nucleus densities is large in transmutation calculation, now existing multi-group WIMS libraries are not suitable for transmutation calculation. This paper makes a study for the parameters value choice such as weight spectrum and background cross-section σ0 in NJOY. With the new parameters value, produce suitable multi-group data of FP and a new library for transmutation calculation. In purpose of comparing these two libraries, build a simple transmutation cell model in HFETR. Achieve the cell calculation separately by WIMSD with new library and original library. Then compare the results of parameters such as K-INF, flux, and absorption reactions. The results show that the values of these parameters are different in resonance energy range, so it is necessary to think over the resonance of FP when a multi-group library is produced for thermal reactor transmutation.
