Embodiment Construction
[0028] In the prior art, two power sources are required to be available when cold-state functional tests are performed in nuclear power plants, that is, the main power source and the auxiliary power source are used together, or the main power source and the emergency diesel engine generator are used together. However, the present invention provides a new power supply method for cold-state function test when the main power supply is unavailable, that is, the cold-state function test is carried out by using auxiliary power supply and emergency diesel engine for power supply. First of all, in the prior art, the design of the auxiliary power supply in the power supply system only considers starting the No. 1 main pump, and does not consider starting the No. 2 and No. 3 main pumps. During the test, the technical problems that must be solved are: first, which measures can be taken to run the three main pumps; second, which measures are taken to make the safety acceptable.
