Calculation and Verification Method and Device for Containment Leakage Rate

Abstract

The invention belongs to the technical field of performance testing of a nuclear power control system. In order to solve technical problems that a professional testing tool is needed and the data collection environment is difficult to be constructed in containment leak rate calculation in the prior art, the invention provides a method and apparatus for calculating and verifying a containment leak rate based on combination of an analog simulation technique, so that calculation of a containment leak rate is completed rapidly. The method comprises: S1, compiling a simulation test tool and a containment leak rate calculation and verification tool; S2, reading testing verification source data by using the simulation test tool; S3, controlling an on-line containment leak rate monitoring system to work based on the source data so as to calculate a containment leak rate A; S4, carrying out operation based on the source data by using the containment leak rate calculation and verification tool to calculate a containment leak rate B; and S5, comparing the calculation result A with the calculation result B and verifying correctness of the calculation function of the on-line containment leak rate monitoring system based on the comparison result.

Description

technical field [0001] The invention relates to the technical field of performance testing of nuclear power control systems, in particular to a method and device for calculating and verifying containment leakage rates. Background technique [0002] The full name of the containment vessel is the nuclear reactor containment vessel, or the reactor containment vessel, containment building or containment body, safety plant, and safety bunker. The shell building of the reactor and equipment is used to accommodate the reactor pressure vessel and part of the safety system (including the main system and equipment of the primary circuit, and the shutdown cooling system), completely isolating it from the external environment, and is expected to realize the function of a safety protection barrier. Therefore, it is required that the performance of the containment vessel must be able to meet the design requirements, for example, the leakage rate parameters of the containment vessel need t...
