前言反应堆压力容器像常规电站那样,为保证它在整个服役期中连续安全运行,要求定期检查。但由于它的放射性,所以实现这种检查困难较大。检查的时候,要求将它浸没在15～30公尺深的水中,以便对检查人员有适当的防护,并且要在大于上述距离处遥控操纵检验设备。英国原子能管理局研究动力堆的安全和检查已近20年。在此期间,曾连续地发展和改进了 Foreword Reactor pressure vessels, like conventional power plants, require periodic inspections to ensure they run continuously and safely throughout their service life. However, due to its radioactivity, it is more difficult to achieve this inspection. During inspection, it is required to immerse it in water at a depth of 15 to 30 meters in order to provide appropriate protection to the inspectors and to remotely pilot the inspection equipment at a distance greater than the above distance. The British Atomic Energy Authority has studied the safety and inspection of power reactors for almost 20 years. During this period, it has been continuously developed and improved
