Abstract

Abstract

Reactor pressure vessel is one of the most important equipments of PWR nuclear power plants.The life of nuclear power plants depends on the life of RPV.Based on the research of irradiation embrittlement of RPV materials,a comparison among the design of material,structure design,irradiation surveillance of M310,CNP1000,AP1000 and EPR is made in this paper,and also a discussion for 60-year design life is taken.Then several measures meeting 60-year design life of RPV are put forward.
- Reactor pressure vessel,
- Irradiation embrittlement,
- 60-year design life,
- Improvement analysis
