Description
Technical field
The present invention is suitable for nuclear power field, and in particular to a kind of monitoring system for primary Ioops cooling temperature Measurement channel
And monitoring method.
Background technique
Nuclear power plant's primary Ioops major function is to flow coolant circulation, the heat that nuclear fission in reactor core is generated
It is transferred to secondary circuit, while cooling reactor core, prevents fuel element from burning or damaging.If primary Ioops temperature is too low, it is unable to satisfy
Nuclear power plant's power generation needs；If primary Ioops temperature is excessively high, it may cause fuel can damage even fuel pellet and melt, jeopardize electricity
It stands safe.Therefore the measurement and display of nuclear power plant's primary Ioops coolant temperature, safety and economy to nuclear power plant are played to pass
Important influence.
Nuclear power plant's primary Ioops coolant temperature measurement process passes through whole Measurement channel and completes, including narrow range and wide-range
Temperature sensor and its corresponding channel handle plate.Temperature sensor (English name: temperature
Transducer) refer to the sensor that can be experienced temperature and be converted into usable output signal.Contact can be divided by measurement method
With contactless two major classes, it is divided into two class of thermal resistance and thermocouple according to sensor material and electron component characteristic.In nuclear power plant
In the measurement of primary Ioops coolant temperature, using contact thermal resistance temperature sensor.Channel processing plate then mainly undertakes temperature
The channel functions such as distribution, acquisition, the transmission of signal.
Currently, nuclear power plant's analog quantity instrument generally takes the intersection between periodic check method or multi-path redundancy data to compare
Method guarantees sensor performance and reliability.
For taking the instrument of periodic check maintenance policy, checking procedure needs to consume heavy workload, and most of feelings
It is being verified under condition as a result, it has been found that sensor states are good.Meanwhile will do it the disassembly and installation of sensor in checking procedure, these
Operation may be damaged sensor or lead to sensor measurement data mistake because installation is incorrect.Due to primary Ioops temperature sensing
The specific position of device, operator can receive a large amount of dose of radiations in disassembly process, while can also generate a large amount of radioactivity
Waste.
For taking the intersection between multi-path redundancy data to compare the instrument of maintenance policy, although sensing can not dismantled
Status assessment is carried out in the case where device, but the data for only using sensor output are judged, can not be passed from comprehensive judgement
Sensor state.And important instrument as primary Ioops coolant temperature sensor, only rely on sensor output can not carry out it is accurate,
It fully assesses.Meanwhile conventional cross comparative approach is just for single reaction heap state, and the verification of primary Ioops temperature sensor should be
It will do it under differential responses heap state.
