安全是核能事业发展的生命线.在核电发展的70年历史上,曾经发生过三次核电厂严重事故,每一次事故的发生都对世界核电的发展走向产生了深远的影响.为了全面汲取三次核电厂严重事故的教训,分析了三次严重核事故形成的原因与影响的异同;立足中国压水堆核电发展现状,探讨了从三次严重事故中应获得的启示,提出未来我国压水堆核电站安全方面的提升和研发方向,指出发展核电是中国实现"双碳"目标和能源安全的客观需要与现实选择.
Safety is the lifeline of the nuclear industry.In the 70-year history of nuclear power development,there have been three serious nuclear accidents.Every accident has a profound impact on the nuclear power de-velopment in the world.In order to fully draw on lessons learned from the three serious accidents,this paper analyses the similarities and differences of the causes and influence of the three serious accidents.Based on the status quo of China's PWR technology of nuclear power development,the enlightenment should be obtained from three serious accidents is discussed,and the future safety improvement and development direction of pres-surized water reactor in China is put forward.It is pointed out that developing nuclear power is the objective need and realistic choice for China to achieve the"double carbon"goals and energy security.
