辐照性能是影响反应堆压力容器使用寿命和运行安全的重要形式.本文阐述了影响反应堆压力容器辐照脆性的主要因素,并从反应堆压力容器钢的化学成分、生产工艺和辐照后退火等方面提出了控制反应堆压力容器钢辐照脆性的主要措施.%Irradiation property is the main factor to influence the use life-time and operation safety of reactor pressure vessel (RPV). The main influencing factors of RPV steel irradiation brittleness are discussed in this paper, and the control measures are provided in chemical composition, manufacturing process and annealing after radiation to improve RPV steel irradiation brittleness.
