In this work, a neutron-physical model of the APR-1400 water-moderated power reactor was developed and verified using the MCNP6 code. An active zone with a detailed description of the design elements was developed. The verification of the model will provide a reliable basis for strategic planning of further support for the operation of the reactor. The results can be used to optimize fuel cycles and assess the impact of new design solutions.
