Problems solved by technology

[0012] However, from a design point of view, the symptom-oriented accident handling guidelines can not only deal with design basis accidents, but also deal with a large number of design expansion conditions, so the list of initiating events determined at the beginning of the design often contains hundreds or even more than thousands of initiating events, each of which would result in an almost unacceptable workload if analyzed and confirmed one by one using a computing platform based on the best estimator

Abstract

The invention belongs to the technical field of nuclear power plant operation, and relates to a function recovery guide rule confirmation method based on an optimal estimation system program. The confirmation method sequentially comprises the following steps: (1) analyzing a typical working condition confirmed by a selected function recovery guide rule; (2) determining monitoring parameters of optimal estimation system program screening calculation; (3) calculating working condition characteristics based on the optimal estimation system program; (4) analyzing an envelope working condition confirmed by a function recovery guide rule; (5) performing operation response confirmation if the function recovery guide exists; (6) making a non-coincidence item processing scheme and carrying out corresponding processing; and (7) modifying the guide rule according to the non-coincidence item processing result. By means of the function recovery guide rule confirmation method based on the optimal estimation system program, whether the designed function recovery guide rule can correctly diagnose and effectively process all accident working conditions needing to be considered or not can be systematically and comprehensively checked.

Description

Technical field [0001] The invention belongs to the technical field of nuclear power plant operation, and relates to a method for confirming function recovery guidelines based on an optimal estimation system program. Background technique [0002] The accident handling guidelines of nuclear power plants are the guiding documents of accident handling procedures (EOP), which describe accident handling strategies and relevant information required for the preparation of accident regulations. Therefore, they are important design documents related to the safety of nuclear power plants. [0003] In the field of nuclear power, there are currently three types of accident handling procedures widely used internationally, namely, event-oriented, state-oriented, and symptom-oriented. The symptom-oriented method is based on the probability theory method of accident analysis. It uses several safety-related parameters as symptoms to supervise the safety of nuclear power plants. It can effectively d...
