Embodiment

[0046] Taking a domestic pressurized water reactor nuclear power plant as an example, its functional requirements analysis layers are as follows:

[0047] Tier 1: The overall goal of the nuclear power plant, which is to generate electricity and prevent radioactive releases.

[0048] Layer 2: Second-layer sub-goals, which decompose the general goal, among which the general goal of power generation can be decomposed into heat generation, etc., and the general goal of preventing radioactive release can be decomposed into fuel cladding integrity, etc.

[0049] Layer 3: Three-layer sub-goals, the second-layer sub-goals are further decomposed into three-layer sub-goals, including reactivity balance, fuel cladding heat balance, etc. Here, the thermal energy generated by the second-level sub-goal and the integrity of the fuel cladding are decomposed and the three-level sub-goals are reactivity balance and fuel cladding heat balance.

Abstract

The invention belongs to the design technology of operating rules of nuclear power plants, and provides a task analysis method for operating strategy development. The method includes functional requirement analysis and operation task analysis. The functional requirement analysis proceeds from the overall operation goal of the nuclear power plant and decomposes layer by layer to obtain all operating functions of the nuclear power plant and all systems, sub-functions, equipment and support systems; the operational task analysis is based on the analysis of functional requirements, starting from the operational tasks of the nuclear power plant, analyzing and decomposing the operational tasks, and finally forming an operational strategy framework for completing the operational tasks of the nuclear power plant, Provide a reference for the development of operational strategies. The invention ensures the completeness of the operation means selected in the operation strategy, and can provide a feasible, reasonable and effective operation strategy formulation method for a new reactor type without operation experience reference.

Description

technical field [0001] The invention belongs to the design technology of nuclear power plant operating procedures, and in particular relates to a task analysis method for operating strategy development. Background technique [0002] Nuclear power plant operating procedures are operating documents that guide nuclear power plant operators to perform various operations and monitor unit systems, and deal with system and equipment failures and various accidents. Taking the domestic pressurized water reactor nuclear power plant as an example, its operating procedure system generally includes system regulations, overall operating procedures, alarm procedures, fault operation procedures, accident operation procedures, and severe accident management guidelines. The situation is different. The validity and rationality of various operating procedures of nuclear power plants are of great significance to ensure the safe operation of nuclear power plants and ensure the economic benefits ...
