Abstract

In order to meet the requirements of NNSA, IAEA, NRC, ONR and ASN on the first of a kind test for the new type PWR nuclear power plant, based on the analysis of new design concepts and new design features of the EPR unit and the engineering practice of PWR, this paper proposes a method to determine the first of a kind test by using the control variable selection principle and the five-step selection process. Project practice has proved that this method can ensure the smooth and effective implementation of the commissioning program, and can completely verify the new concept design and the performance of new characteristics, so as to ensure the safe and stable operation of the reactor nuclear power plant. This method can also be applied to other types of PWR nuclear power technology like HPR1000.
