Abstract

One of most important tasks in reactor physics is correct description of reactor radiation interaction with facility materials. Structural, fuel, shielding and other materails are consist of practically all Mendeleev table elements. Interaction of reactor radiation (neutrons and photons) with nuclei of izotopes of each periodic table element divide on several of types (fission, absorbtion, scattering etc) and have difficult angle and energy behavior. Continuous energy angular description of dependencies sometimes unavailable or unnecessarity for engeneering (series) calculations for determine of particle numbers in small far away point (detector) from radiation source. Therefore, specialists use averaged data (groups) about interaction of reactor radiation with material.
Paper contains results of the ABBN-RF data groups system testing based on the ROSFOND russian evaluated nuclear data library files in tasks of ionized radiation transfer and generation secondary photon radiation via calculations of simple spheres models are containing shielding materials of nat-ural isotopes composition and density with neutron californium source in center sphere.
