摘要
Abstract
To meet the demands of the development of the AMPX formatted multi‐group neutron‐photon coupled constant library for the next generation nuclear power system , thorium molten salt reactor (TMSR) ,based on the evaluated nuclear data library , CENDL‐TMSR recommended for the TMSR ,and thermal scattering data sub‐library and photon‐atom interaction data sub‐library of ENDF/B‐Ⅶ.1 ,an AMPX formatted 238‐neutron and 48‐photon coupled multi‐group constant library was developed using neutron‐photon coupled group constant processing system NPLC‐2 .The library contains 400 nuclides and 12 thermal scattering materials ,with five temperatures ranging from 300 K to 2 500 K . T he library utilizes the narrow resonance approximation for the resonance self‐shielding calculations .For some important actinium series nuclides ,the Nordheim method was provided to perform the resonance self‐shielding calculations . T he preliminary critical and shielding benchmark verifications confirm the reliability of this new library .关键词
