HPR1000 commissioning stages and commissioning tests design

As the generation III nuclear power plant developed by China, HPR1000 should satisfy the requirement of the latest nuclear safety codes and standards. The nuclear safety codes request the whole commissioning task should be divided into several stages and sub-stages according to the safety requirements and technique/management requirements. Base on the latest national and international guides and standard, the HPR1000 commissioning stages and the main tests of each stage are designed by analyzing its characteristics deeply according to the safety requirements and technique/management requirements, in order to assure the commissioning task to be done successfully. To make them been done safely, efficiently and orderly, the commissioning tasks should be taken place strictly following the commissioning stages and step by step, meanwhile the test results should be evaluated and supervised before turning to the next stage, so that the sufficient assurance could been provided to the final satisfaction of HPR1000's safety goal.
