Intercomparison of Delayed Neutron Summation Calculations among JEF2.2; ENDF/B-VI and JNDC-V2

摘要

We perform intercomparison of delayed neutron activities calculated with JEF2.2, ENDF/B-VI and JNDC-V2 with a simple new method. Significant differences are found at t<20 (s) for major fissioning systems. The differences are found to stem from fission yields or decay data of several nuclides. The list of these nuclides are also given for the future experimental determination of these nuclear data.
