Modular Design on Qualification Test System of Pumps of Nuclear Safety Grade

As a dynamic equipment in the PWR units,the reliability of the pumps is key to the security of whole nuclear power station.In the development of the pumps of nuclear grade 1 and 2,various strict qualification tests shall be carried out,to make sure that the design satisfies the system requirement.The research on the tests of nuclear grade pumps is not much in China.Based on the requirements on the qualification tests for pumps of nuclear grade 2 used in current nuclear power stations,this paper studies the test system design with modular design theory,and discusses the design idea and problem,and then proposes a general design scheme for the test system.
