目前全世界在运行的430多台机组中,只有几台属于三代机组,这些现役的第二代反应堆,都是经过长期考验的技术成熟的堆型,安全水平经过改进和提高符合相关安全标准。近年来,美、法等核电大国经过安全评估进一步提升安全改进项,经评审将本国大部分核电机组的运行寿期从40年的寿期延长到60年。我国在运及在建的绝大部分核电机组,其技术水平
Currently, only 430 of the more than 430 generating units operating in the world belong to the third generation of generating units. These active second generation reactors are mature, proven technologies that have been tested for a long time. The safety standards have been improved and improved to meet the relevant safety standards. In recent years, nuclear power countries such as the United States and France have further upgraded their safety improvements through safety assessment. After the review, the operating life of most nuclear power plants in their country has been extended from a 40-year life to 60 years. The vast majority of nuclear power units under operation and under construction in our country have their technical level
