Моделирование ядерных реакторов является одним из важных этапов обеспечения безопасности и оптимизации их характеристик.

Данная работа посвящена оценке характеристик активной зоны реактора EPR при его различных режимах работы с целью рассмотрения данного типа реактора как возможного кандидата для строительства АЭС в Казахстане. Исследования заключались в разработке расчетной модели реактора EPR и проверке релевантности полученных расчетных данных. Исследования проведены с использованием метода Монте-Карло, реализованного в программе MCNP и позволяющего детально анализировать нейтронно-физические процессы, происходящие в активной зоне реактора. В статье представлены описание реактора EPR, методика проведения исследований, компьютерная модель, результаты моделирования и сравнение расчетных данных с литературными. 

Modeling of nuclear reactors is one of the important steps in ensuring safety and optimizing their characteristics. This work is devoted to assessing the characteristics of the core of the EPR reactor under its various operating modes in order to consider this type of reactor as a possible candidate for the construction of a nuclear power plant in Kazakhstan. The research culminated in the development of a computational model of the EPR reactor and the introduction of analytical methods to obtain additional data. The research was carried out using the Monte Carlo method developed in the MCNP program and designed to analyze in detail the neutron-physical processes occurring in the rector's core. The article presents a description of the EPR reactor, a research methodology, a computer model, simulation results and a comparison of calculated data with literature data.
