Abstract: In order to ensure the safety and reliability of the reactor coolant pump, the integrated design needs to be verified by experiments. The general idea of the design and verification of the reactor coolant pump and the test items for the engineering prototype of the reactor coolant pump are introduced in this paper. The optimal integrated verification test program of the reactor coolant pump is provided and the feasibility of the test program is analyzed. The results show that the integrated verification test for the reactor coolant pump can be achieved by using the small flow test based on the test and analysis of the modules, sub-modules, components and materials of the reactor coolant pump.
