Description

The function of protection system is to protect the integration of three nuclear safety barriers. In case of DBC2-4, the reactor protection system will be initiated automatically to perform the reactor trip function in order to reach control state. Under the construction EPR NPP, reactor trip function is LDNBR and HLPD. LDNBR and HLPD are based on SPND measurement. The SPND based reactor trip function was analyzed, and the protection system function requirement was further analyzed. The results show that the current design can satisfy the standard requirement.
