Embodiment

[0052] The non-residual fault treatment strategy of the main control chamber of the digital pressure hydraulic stack is taken as an example of the analysis method of the present invention:

[0053] 1) The unit has the possibility of unrebertable in each mode of operation, thus determining the working conditions in various operating modes of the unit, and the main control room must be carried out in the main control chamber. Strategy analysis. The main pump determines the strategy used during the retreat process, thus collecting the operability of the main pump as an important factor, and considers the operability of the main pump in the analysis.

[0054] For the anecdote operation, for each initial operating conditions, there is no need to consider the operational strategy of adjacent working conditions, and design the best way to design the best airway.

[0055] In the selection of the retreat strategy, try to multiplex the operation modules of the existing proven procedures, use...

Abstract

The invention relates to a method for analyzing the unavailable fault handling strategy of the main control room of a digital pressurized water reactor nuclear power plant. Working conditions, obtain the list of initial operating conditions of the unit to be designed, and the corresponding operation strategy for each initial operating condition, generate a strategy analysis summary table, merge adjacent working conditions with the same operation strategy, and generate a strategy combination table, Determine the priority of each path in the policy merging table, generate a policy priority table, analyze the priority of the policy, merge and optimize the steps, and complete the overall fault handling strategy. The fault handling strategy designed by the method of the invention can quickly guide the operator to the required operation, improve the pertinence of diagnosis, and reduce unnecessary diagnosis time.

Description

Technical field [0001] The present invention belongs to nuclear power plant design technology, and specifically, it is specifically related to the main control room of digital pressure hydraulic stack nuclear power plants. Background technique [0002] The main control room of the nuclear power plant provides a complete control method for the operator, and the manifer is usually completed in the main control room to monitor the status of nuclear power plants and control of various devices. However, in the event of a situation in which the operator is resident (fire, smoke, etc.), in order to ensure the safety of the power plant, the manner needs to go to the remote stop station operation. The remote stop station allows the operator to complete the appropriate operation to achieve a safe stop. [0003] In order to achieve the above functions, it is used in the nuclear power plant allocated operational procedures to operators in the operation of the "main control room unreholded to...
