Data processing method for nuclear power plant accident processing guide rule confirmation.

Abstract

The invention belongs to the technical field of nuclear power plant operation, and relates to a data processing method for nuclear power plant accident processing guide rule confirmation. The data processing method sequentially comprises the following steps: (1) selecting key function related parameters and respectively extracting data; (2) determining a corresponding relation between the key function related parameters and the power plant state; (3) calculating different working conditions based on an optimal estimation system program, and reasonably judging whether recalculation is needed ornot according to a calculation result; (4) drawing a key function time sequence change table according to a calculation result; and (5) comparing the time sequence change tables under different working conditions, and evaluating the effectiveness of operation intervention. According to the data processing method for nuclear power plant accident processing guide rule confirmation, data observation, screening and processing analysis can be better carried out when symptom guiding accident processing guide rule confirmation work is carried out, and therefore part of confirmation results can be used for nuclear power plant accident processing links related to evaluation and operation intervention.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant operation, and relates to a data processing method for confirmation of nuclear power plant accident handling guidelines. Background technique [0002] The technology of symptom-oriented accident handling guidelines for nuclear power plants has been widely used internationally in recent years because of its clear system strategy and the ability to deal with design basis accident conditions and design extension conditions at the same time. Moreover, my country's nuclear safety guide HAD103 / 01 "Nuclear Power Plant Operating Limits and Conditions and Operating Procedures" stipulates that priority should be given to using symptom-oriented accident handling guidelines to deal with nuclear power plant accidents. In order to better reflect the advancement and safety, the third-generation nuclear power units independently developed by my country have decided to use the symptom-oriented accident...

Problems solved by technology

[0011] However, the symptom-oriented accident handling guidelines deal with different types of accidents, including design basis accidents and design extension conditions, and the handling strategies for various accidents are different. Each accident condition will generate a large amount of simulated calculation data, so the confirmation staff will face many difficulties when judging the correctness of the sympto...
