Ministry of Ecology and Environment's North China Nuclear and Radiation Safety Supervision Station Conducts Special Supervision on Cold Test Release for Tianwan Nuclear Power Unit 8

The Cold Functional Test (hereinafter referred to as the cold test) is the first major comprehensive test for a nuclear power unit transitioning from the installation phase to the commissioning phase. It is a key core link to verify the pressure-bearing capacity and sealing performance of the nuclear island main system and equipment under design pressure conditions, and serves as a critical milestone to ensure the subsequent safe and stable operation of the unit. Recently, the Ministry of Ecology and Environment's North China Nuclear and Radiation Safety Supervision Station (hereinafter referred to as the North China Supervision Station) conducted comprehensive supervision on the cold test control point release for Tianwan Nuclear Power Plant Unit 8. Adhering to the principle of supervision moving forward, the station consolidated the pre-test foundation. Upholding the nuclear safety supervision philosophy of "prevention first, moving the checkpoint forward," the North China Supervision Station focused on the preconditions for the cold test control point release, verified various items pending rectification one by one, and ensured that all hidden dangers were effectively addressed, building a solid safety barrier for the smooth progress of subsequent tests.
