3月27日,中国广核集团宁德核电1号机组首次在役安全壳整体打压试验(简称“CTT试验”)结束。本次试验在安全壳测量系统、内外观检查等多个领域实现了技术创新,确保了试验的安全性、准确性和可靠性,同时创造了中广核历史上最短试验时间。本次CTT试验是中广核大亚湾核电基地外首次电厂和运营公司大修中心合作实施的安全壳打压试验。其中,试验泄漏率测量由电厂首次主导实施,使用了电厂自主开发的安全壳泄漏率测量系统。该系统采取两套数据采集、分析系统同时运行的冗余
March 27, China Nuclear Power Group, Ningde Nuclear Power Unit 1 for the first time in full containment containment test (referred to as “CTT test”) ended. The test has achieved technological innovation in many areas such as containment survey system and internal and external inspection to ensure the safety, accuracy and reliability of the test and at the same time, it has created the shortest test time in the history of CGN. The CTT test is a containment suppression test conducted in cooperation with the first power plant outside the Daya Bay nuclear power base outside CGN and an overhaul center of an operating company. Among them, the test leakage rate measurement for the first time led by the implementation of the power plant, the use of self-developed power plant leak rate measurement system. The system uses two sets of data acquisition, analysis of the system while running redundancy
