Problems solved by technology

In the design process of the fixed value, the working conditions of the accident handling strategy must include the environmental conditions of high temperature, high pressure and high radiation of the containment, and the instrument error will often deteriorate under such unfavorable environmental conditions

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 assessment and relates to a method for determining accident strategy value of a nuclear power plant based on a containment working condition. The method comprises the following steps: (1) determining a nominal value of a parameter fixed value in an accident handling strategy; (2) Judging and screening the key value of accident disposalstrategy; (3) Determining the instrument error of the key fixed value under the normal and unfavorable conditions of the containment; (4) Analyzing the influence of instrument error on accident handling guideline; (5) Calculation and verification of fixed value conformity analysis; (6) Verification and confirmation. A method for determining accident strategy value of nuclear power plant based oncontainment condition is disclosed, The instrument error under different containment conditions (normal condition and unfavorable condition) can be considered separately, and the influence of instrument error on the key fixed value in accident strategy can be optimized, and two sets of fixed value under normal condition and unfavorable condition can be obtained. Finally, whether the fixed value can meet the requirements of the criterion is judged by calculation and verification.

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...
