I nuclear power station passive variable high cooling water system through acceptance

According to the experts, in the nuclear power plant similar to Japan Fukushima super design reference accident conditions, the system can be reserved by the auxiliary water supply system interface and spent fuel cooling system interface, the high water supply to the natural gravity of the introduction of auxiliary Water supply system or spent fuel cooling system, for its non-active water, for the safety of reactors and spent fuel pool to provide a redundant and successful way.

The system of high water supply capacity of 5200 cubic meters, can deal with extreme natural disasters caused by accident conditions, to meet the core, spent fuel pool more than 3 days of water demand. Probabilistic safety analysis shows that the system contributes significantly to the safety of nuclear power plants and has a greater effect on improving the safety of nuclear power plants. The project demonstration project in Daya Bay nuclear power base has been completed construction and commissioning, and already have to promote the application conditions.

After listening to the project team to report and field visits, the expert group that the project team lasted three years to carry out the non-dynamic emergency high cooling water system development, its design, civil engineering, construction, commissioning, safety analysis and functional verification are in line with relevant standards.
