反应堆压力容器60年设计寿命研究

Research of 60-year Design Life for PWR Reactor Pressure Vessel

反应堆压力容器是压水堆核电厂的关键设备之一,其设计寿命是核电厂寿命的关键因素。从反应堆压力容器的材料、结构设计和在役监督等方面,通过对比分析M310,CNP1000,AP1000和EPR等堆型反应堆压力容器设计,对影响其60年设计寿命的因素进行探讨,同时结合国内反应堆压力容器制造情况,提出满足反应堆压力容器60年设计寿命的一些优化措施。

Reactor pressure vessel is one of the most important equipments of PWR nuclear power plants. Its design life is the key factor for the life of nuclear power plants. Basing on the material, structure de- sign,in- service surveillance and so on, a comparison among M310, CNP1000, AP1000 and EPR is made, and also a discussion for 60 - year design life is taken. Then considering the domestic manufacture of RPV, several measures meeting 60 -year design life of RPV are put forward.
