Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] The process flow of the exemplary method of determining the value of the nuclear power plant accident strategy based on the containment working conditions of the present invention is as follows: figure 1 shown, including the following steps.

[0036] (1) Determine the nominal value of the parameter setting in the accident handling strategy

[0037] Based on the analysis of the accident handling strategy, set corresponding fixed values ​​for the tasks or functions to be completed in the steps, and analyze the validity of the set fixed values ​​through compliance analysis and calculation, finally form a complete set of accident handling strategies, and Confirm the value of fixed nominal value in it.

[0038] (2) Screen the key fixed value of the accident handling strategy

[0039] The key fixed value in the accident handli...

Abstract

The invention belongs to the technical field of nuclear safety evaluation, and relates to a method for determining the accident strategy value of a nuclear power plant based on containment working conditions. The method comprises the following steps: (1) determining the nominal value of the parameter setting in the accident handling strategy; (2) judging and screening the key setting values ​​of the accident handling strategy; (3) determining the normal and unfavorable working conditions of the containment Instrument errors of key fixed values; (4) Analysis of the impact of instrument errors on accident handling guidelines; (5) Analysis and calculation verification of fixed values ​​compliance; (6) Verification and confirmation. Utilize a kind of method of determining nuclear power plant accident strategy value based on containment working condition of the present invention, can consider the instrument error under this working condition separately for different containment working conditions (normal working condition and unfavorable working condition), and combine instrument The impact of errors on key fixed values ​​in accident strategy is optimized and calculated, and two sets of fixed values ​​under normal working conditions and unfavorable working conditions are obtained. Finally, through calculation and verification, it is judged whether the fixed value can meet the requirements of the criterion.

Description

technical field [0001] The invention belongs to the technical field of nuclear safety evaluation, and relates to a method for determining the accident strategy value of a nuclear power plant based on containment working conditions. Background technique [0002] The nuclear power plant system is complex and has many operating parameters. Once an accident condition occurs, the nuclear power plant is considered to be in an emergency state. At this time, the operator is required to respond quickly, correct the deviation of the working condition, and take necessary actions to avoid or mitigate possible consequences. . Accident handling procedures are an important part of nuclear power plant defense in depth. It is directly related to the operation safety of nuclear power plants and plays an important role in limiting the development of accidents and ensuring the safety of reactors. [0003] Incident handling strategies can be used to mitigate and limit the consequences of incide...
