Abstract: The paper presents experience gained in the development and verification of neutron and photoatomic libraries for the specialized computational codes MCPV and MCSS, which are used for the analysis of radiation exposure of VVER reactor pressure vessels, irradiation parameters of reactor internals, and irradiation conditions of surveillance specimens. Approaches to the generation of multigroup neutron libraries with different nuclide compositions and energy coverage, as well as neutron and photoatomic libraries in continuous-energy representation in the ACE format, are discussed. The verification of the developed libraries was performed by comparing calculation results obtained using different Monte Carlo codes in benchmark problems of neutron and photon transport in a simple spherical geometry.
Keywords: reactor dosimetry, neutron and photoatomic data libraries, Monte Carlo method, MCPV, MCSS.
