Description
Technical Field
The invention relates to the technical field of performance testing of nuclear power control systems, in particular to a containment leakage rate calculation verification method and device.
Background
The containment vessel is called as a nuclear reactor containment vessel, or called as a reactor containment vessel, a containment building or a surrounding body, a safety plant and a safety bunker, is a building which forms the outermost periphery of a pressurized water reactor, and refers to a housing building which contains most systems and equipment of a nuclear steam supply system and is used for containing a reactor pressure vessel and part of safety systems (including a primary system and equipment and a reactor shutdown cooling system) to completely isolate the reactor pressure vessel and the part of safety systems from the external environment, and the function of a safety protection barrier is expected to be realized. Therefore, containment performance must be able to meet design requirements, such as containment leak rate parameters that need to be controlled within predetermined ranges.
In the prior art, an on-line containment leak rate detection system (i.e., an EPP dedicated system) is a component of a BOP (auxiliary system) of a nuclear power plant, and monitors the containment leak rate during the operation of the unit on line, and monitors the change in containment tightness so as to maintain the atmospheric pressure in the containment within an allowable range of (-40 to +60hPa (g), (1hPa 100 Pa)). The EPP special system mainly calculates the leakage rate of the containment according to the conservation principle of the mass of the gas in the containment, records and stores all relevant data and calculated relevant parameters in the monitoring process in real time, and can also carry out reanalysis calculation on all data derived by the online detection system. When the leakage rate reaches the operation limit value, an operator is informed to take necessary actions in time, and the calculation result of the EPP special system plays a key role in guaranteeing the safe and efficient operation of the nuclear power station.
As shown in fig. 1, in the prior art, a test tool is used for calculating a containment leakage rate to send source data to an EPP dedicated system, and the EPP dedicated system acquires input of the test tool through an acquisition station board card and performs calculation to obtain a calculation result of the system, and the calculation result is compared with a power plant operation result or a manual calculation result to verify the correctness of the calculation result of the system.
The inventor discovers that in the process of implementing the invention: the containment leakage rate online detection system has the following particularity: a. the acquired data involved in one calculation is more, and 18 source data are required to be acquired; b. the calculation needs long continuous time, and one complete calculation needs 5-20 days according to different verification functions; c. the complexity of the calculation formulas is high, and the calculation formulas are nested with each other; d. the branch probability of the calculation result is high. Therefore, the containment leakage rate calculation process in the prior art has the following defects:
1. the difficulty of building a data acquisition environment is high; if all board cards still need to be matched and a test tool is set up when only the calculation function needs to be verified, too much manpower and material resources are consumed, and the test time is increased.
2. The calculation needs long time, one complete calculation needs 5-20 days, while multiple calculation verifications are often needed in normal verification, and the existing calculation verification method can greatly prolong the test time.
3. The test result is not accurate enough, and the previous calculation result of the power plant and the system calculation result cannot be ensured to be completely consistent due to the inconsistency of the operation data, the difference of the configuration parameters of the power plant and the inaccuracy of the previous operation data of the power plant, so that the correctness of the calculation function of the containment leakage rate online monitoring system cannot be accurately explained by comparing the calculation results of the power plant and the system calculation result; and the manual calculation contrast is used, because the complexity of the calculation formula is high, the error is easy to occur, and the time is consumed.
4. The coverage is not comprehensive, because the operation condition of the power plant is generally stable, the historical data of the power plant can be stored and obtained, and the multiple conditions related to the calculation model, especially the condition of alarming, cannot be verified completely.
