Abstract

The paper presents a software package for justifying radiation safety is developed as part of the neutron-physical calculation modules for fuel-containing components based on diffusion approximation, Sn approximation and Monte-Carlo method, nuclide kinetics calculation module, radiation sources calculation module, direct radiation field calculation modules (PS) based on the Sn approximation and the Monte Carlo method together with the constant support system.
Since it was planned to use ready-made independent calculation modules, the main problem was to organize the joint work of the calculation modules within the radiation safety justification code by developing a methodology for combining the modules into a calculation chain and creating the necessary tools for this.
At present, the code being developed is ready for one-time calculations by developers. The field of application is the cores of fast reactors, fuel and irradiated non-fuel materials storage units, objects of a closed nuclear fuel cycle.

Keywords
