Abstract: The multi-group transport library MUSE-F1.0 based on ENDF/B-Ⅶ.0 with 175-group neutron and 42-group photon was developed by NJOY99. Weighting function is thermal--1/e--fast reactor—fission+fusion, and Legendre order is six. The library was validated by a series of critical and shielding benchmarks. The shielding test involves nuclear data including fission reactor, fusion reactor and accelerator. The result shows that MUSE-F1.0 is suitable for critical and shielding calculation. And it is competent for the application of fast neutron reactor design.
