摘要
Abstract
The differences between 235U fast fission delayed neutron group parameters in ENDF/B7, JEFF3. 1, JENDL3. 3, CENDL2. 2 and Keepin datum were analyzed. The delayed neutron group parameters were validated by experiments on CFBR- II. The Keepin delayed nutron group parameters are more accurate than delayed nutron group parameters in the primary nuclear databases. The eight-group delayed neutron parameters in JEEF 3. 1 are better than six-group delayed neutron parameters in other databases.关键词
