Method for detecting leakage of water tank of nuclear power plant

The invention relates to a nuclear power plant water tank leakage detection method comprising the following steps: obtaining historical state data of a water tank, and obtaining a first parameter and a second parameter of a calculation model according to the historical state data; target state data of the water tank in the target time period are obtained, and a target state value is obtained according to the target state data; calculating a theoretical state value according to the target state data, the first parameter and the second parameter; and obtaining a leakage result according to the target state value and the theoretical state value. According to the method, the calculation model is established by utilizing the historical state data, and the theoretical state value is obtained by combining the obtained target state data, so that whether the water tank leaks or not is accurately judged. And the accuracy and the response speed of leakage detection are improved. 本发明涉及一种核电厂水箱泄漏探测的方法，方法包括以下步骤：获取水箱的历史状态数据，
