Abstract: Firstly the Nuclear safety laws and guidelines was introduced briefly, and then the requirement of safety systems in nuclear safety laws and guidelines was decrebied, and the adaptability of passive core cooling system and passive containment cooling system commissioning to laws and guidelines was analysied. The results show that the commissioning of AP1000 passive safety systems are adptive to the laws and guidelines of nuclear safety, but the sequence of the related tests should be optimized. When the laws and guidelines are updated in the future, these commissioning of passive safety systems and these tests cannot be performed on site due to test conditions should be taken into account.
