AP1000 nuclear power station plate heat exchanger thermal state performance acceptance method

The invention discloses an AP1000 nuclear power station plate heat exchanger thermal state performance acceptance method, which comprises the following steps: 1, installing and completing main body equipment; 2, preparing instruments and meters, and measuring required parameters for acceptance; 3, when parameters of the process system reach test conditions, keeping the temperature and the pressure basically constant under the conditions; 4, recording a group of data; 5, carrying out heat balance analysis; and 6, analyzing heat exchange efficiency, calculating a manufacturer UA value and a test UA value, wherein if the deviation between the test UA value and the UA value calculated by the manufacturer is within 10%, the heat exchange efficiency analysis is accepted, and the acceptance is passed, if the UA value of the manufacturer is 10% greater than the test UA value, the equipment performance is superior to the technical specification requirement, the heat exchange efficiency analysis can be accepted, and th
