摘要
分析了核反应堆抗震的科学原理;据中国地震灾难的实际经验,探讨核安全的动力技术,利用地震波P波,通过I&C/FCS-DCS,在破坏性S波到来前,触发动态安全停堆系统,避免地震核引发灾难。介绍了2007年新潟6.8级地震震中9km处柏崎市刈羽郡世界最大的8.2kMWe核电厂无核事故的典型案例。
The scientific principle of protecting NPP against earthquake is analyzed.The dynamic principle of functional safety is discussed by the disaster experiences of earthquake in China.The P component of the seismic wave can be use as triggering signal to shot down the nuclear pile through I&C/FCS-DCS before the catastrophic S wave arrival to avoid the nuclear accident.The nuclear functional safety of the NPP is introduced by means of the Kariwa Kashiwazaki Niigata NPP the world biggest NPP,where is just 9 km nearby the Epicenter of 2007 Ms 6.8 Seism at Okiis Chuetsu Niigata.
