Абстракт: The nuclear materials of Reactor Pressure Vessel (RPV) in Nuclear Power Plant (NPP) are submitted to nigh temperature and pressure. A neutron induced embrittlement and thermal ageing of RPV materials are going. Scoping safety exploitation of NPP the embrittlement process must be study. The irradiation causes a shift of the initial critical brittleness temperature 0KT to the higher values (KTΔ). There are two ways for receiving the critical temperature shift – numerical and experimental. The scope of currentwork is to be made analysis of four numerical methods. The theoretical results are compared with data from surveillance specimens. It has a good correlation between calculated data (by Methods 2 and 3) and experimental one. The study is intended to assist in the development of the process of embrittlement of the RPV materials.
