The paper presents the results of adaptation of existing algorithms of neutron-physical processes in the nuclear reactor simulation and their implementations to supercomputers environment. An analysis was made of current simulation algorithm implementation in order to identify its most resource-intensive parts. The individual software components of the model and their relationships have been investigated to identify opportunities for parallelization. The parallel version of the simulation algorithms was developed and implemented. Implemented algorithms have been tested and their algorithmic efficiency was investigated.

Keywords: parallelization of programs, the effectiveness of parallelization, neutron physics, computer simulation of neutron-physical processes
