Bleed condenser pressure relief valves for candu~direct R reactors

摘要

Four test programs of Bleed Condenser pressure relief valves 9RVs) have been completed. This work was intitiated following two events in which Bleed Condenser RVs were damaged. During one event, the piping connecting one of the RV's to the Bleed Condenser also failed. This paper describes the investigations of these events and subsequent testing of several different RV designs. Based on the test results, pressure relief valve designs suitable for this service have been determiend. Lessons learned are applicable to pressure relief valves in liquid services.
