A Basic Discussion on the Safety Improvement of Chinese Nuclear Equipment Design

摘要

Fukushima nuclear accident taught us a couple of bigrnlessons in nuclear safety. Presently, Chinese CAP1000/CAP1400 projects are based on the AP1000 technology. Lessons learned from the Fukushima nuclear accidents are applied to the CAP1000/CAP1400 projects. The safety margins are further improved by incorporated a number of additional measures, such as waterproof plugging plan, make-up coolant after 72 hours, redundant power supply after 72 hours (e.g. mobile diesel generator), water level monitoring of spent fuel pool, environment monitoring improvement, enhanced emergency command center and so on, are included in CAP1000/CAP1400 projects.
