Containment building is the final barrier for radioactive releases from a nuclear power plant (NPP). Preserving its integrity will minimize these even in case of severe accident with core degradation and melt discharge containment accompanied pressure temperature increase. Installation venting system ability to filter fission products preferred way deal issue present future NPPs, especially aft...

In this work, a brand new passive safety injection system has been designed for the ocean-based Qinshan Phase I nuclear power plant to update and replace traditional active ones. The is made up of high pressure, medium lower pressure system, two-stage automatic depressurization system. To evaluate performance, double-ended cold leg large break LOCA analyzed by best-estimated analysis RELAP5 cod...
