Research on Reactor Internals Sealing Structure of Supercritical Water Cooled Reactor

In order to realize the dual process design of China supercritical water cooled Reactor（CSR1000）,it is necessary to set sealing structure in more than one place inside the reactor.In view of the use experience of the sealing structure in the power station PWR and other industries,it is feasible for the use of O-ring and C-ring in the seal design of the CSR1000 reactor internals.The loading situation of the seal ring is simulated and some key parameters such as decrement and springback amount are calculated and analyzed by taking O-ring for example.
