Abstract
The paper describes the KIR-P program designed for calculating the kinetics of nuclear reactors using the factorization method, when the neutron flux is represented as a product of an amplitude multiplier and a form function, within the framework of classical adiabatic and quasi-static approximations.
The form function and the effective fraction of delayed neutrons and the effective lifetime of fission neutrons included in the equations of the above approximations are calculated by the Monte Carlo method.
Special attention is paid to the description of the Monte Carlo calculation algorithm of the form function in the quasi-static approximation. The authors are not aware of the works published in the world literature, in which special attention is paid to this problem.
The results of calculations of some test variants are presented.
The advantage of the KIR-P program over KIR (a program for calculating the kinetics of nuclear reactors without approximations) is in faster, at times, modeling of the kinetic process. And the advantage over engineering.
