摘要
Abstract
An improvement for Qinshan Nuclear Power Plant Phase 2 unit 1&2 ,in which the power‐operated valves are replaced with the spring‐loaded valve with setpoint adjustment for the 1st group safety valves of steam generators ,would be adpoted on the basis of comparison with similar improvement implemented in Qinshan Nuclear Power Plant Phase 2 unit 3&4 .The feasibility was evaluated from several aspects ,including mechanical design ,instrument & control design and safety analysis .On the premise of guaranteeing safety ,this improvement can simplify design ,observably reduce project costs and avoid increasing the potential probability of the reactor trip risk induced by complication of the system and control logic .关键词
