Abstract

As the fusion-driven subcritical energy reactor has wide and complex energy spectrum,multigroup cross-section library needs to be developed for its design requirement.A 187-group neutron cross-section library is developed by using NJOY code.With transport code ANISN,enriched uranium critical sphere benchmarks and uranium sphere model with water cavity are calculated to validate the multigroup cross-section library Multi-layer shell model of subcritical energy reactor is calculated,and the results are compared with MCNP5.The results show that the multigroup cross-section library is correct and can be used for subcritical energy reactor design,and the reaction rates and neutron spectra in subcritical energy reactor can be calculated as well.
