源项调查技术在某核电站源项异常分析中的应用实践

Abstract

Abstract: Source term investigation technology has been widely applied in nuclear power plants both domestically and internationally. The information obtained from source term investigation, such as radionuclide types, surface contamination activity, and contribution ratio of radionuclide dose rate, is important source term basic data. These data provide important support for the development of source term control strategies, the analysis of source term anomalies, radiation shielding design, and archiving reactor unit source term information. This article introduces the source investigation of a CPR1000 unit using the CZT gamma spectrum measurement system and the practical experience of assisting in determining the causes of reactor unit source term anomalies, through the results of source term investigations.

Key words: Source term investigation, Anomaly analysis, Nuclear power plant
