【Abstract】 The hot life test has been done to testify whether the longeval Control Rod Drive Mechanism can meet the requirements of the design indexes. This paper describes the purpose, requirement, device, test process and results of longeval Control Rod Drive Mechanism hot life test for Advance pressurized water reactor(APWR). The mechanism has reached 8.51 million steps, during the test, the mechanism runs normally, drop time satisfies the design requirement. The results of the test proves that the design and manufacture of the mechanism meet the requirements of the design indexes.更多还原
