Analytical method for unavailable failure treatment strategy of main control room in digital pressurized water reactor nuclear power plant

Abstract

The invention relates to an analytical method for unavailable failure treatment strategy of a main control room in a digital pressurized water reactor nuclear power plant. According to the method, ananalytical principle of the unavailable failure treatment strategy of the main control room in the digital pressurized water reactor nuclear power plant is established, various initial working conditions of a machine set are analyzed, a list of the initial operation working conditions of the machine set to be designed and operation strategy corresponding to each initial operation working conditionare obtained, a strategy analysis table is formed, the adjacent operation working conditions with same operation strategy are merged to form a strategy merging table, priority of each path in the strategy merging table is determined, a strategy priority table is formed, priority of the strategy is analyzed, steps are merged and optimized, and therefore the overall failure treatment strategy is completed. According to the failure treatment strategy designed by the method provided by the invention, an operator can be quickly guided to required operation, pertinence of diagnosis is improved, andunnecessary diagnosis time is reduced.

Description

technical field [0001] The invention belongs to the design technology of nuclear power plants, and in particular relates to a method for analyzing the unavailable fault processing strategy of a main control room of a digital pressurized water reactor nuclear power plant. Background technique [0002] The main control room of the nuclear power plant provides complete control means for the operator, and the operator usually completes the monitoring of the status of the nuclear power plant and the control of various equipment in the main control room. However, in the event of a situation affecting the habitability of the operator at the main control (fire, smoke, etc.), in order to ensure the safety of the plant, the operator needs to transfer to the remote shutdown station for operation. The remote shutdown station enables the operator to perform appropriate operations to achieve a safe shutdown. [0003] In order to realize the above functions, special operating procedures a...

AI Technical Summary

Problems solved by technology

On the remote shutdown panel of a traditional power plant, limited by the layout space, only part of the functions in the main control room can be realized; while the remote shutdown station of a digital nuclear power plant is no longer limited by the layout space, its operator workstation and The operator workstation in the main control room is fully functional with the same functionality
