Abstract

The basics of physical approach to the problem of prediction of RPV metal life time are presented. In contrast to existing one, it is based on the fundamental laws of transition of metal from ductile to brittle state. It gives unified approach to description all totality of factors (such as metal properties and conditions of thermo-power load of RPV at PTS), which governs the critical permissible fluence. Examples of application of the approach offered are given.
