Description
Technical Field
The invention is suitable for the field of nuclear power, and particularly relates to a monitoring system and a monitoring method for a loop cooling temperature measurement channel.
Background
The primary loop of the nuclear power plant has the main function of enabling a coolant to flow in a circulating mode, transmitting heat generated by nuclear fission in a reactor core of the reactor to the secondary loop, cooling the reactor core and preventing fuel elements from being burnt or damaged. If the temperature of a loop is too low, the power generation requirement of a nuclear power plant cannot be met; if the temperature of the primary circuit is too high, the fuel cladding can be damaged and even the fuel pellets can be melted, and the safety of a power station is endangered. Therefore, the measurement and display of the temperature of the primary loop coolant of the nuclear power plant play a crucial role in the safety and the economy of the nuclear power plant.
The temperature measurement process of the primary loop coolant of the nuclear power plant is completed through an integral measurement channel, and the integral measurement channel comprises narrow-range and wide-range temperature sensors and corresponding channel processing plates thereof. A temperature sensor (english name: temperature transducer) refers to a sensor that senses temperature and converts it into a usable output signal. The measurement method can be divided into a contact type and a non-contact type, and the measurement method can be divided into a thermal resistor and a thermocouple according to the characteristics of sensor materials and electronic elements. In the temperature measurement of the primary loop coolant of the nuclear power plant, a contact type thermal resistance temperature sensor is adopted. The channel processing plate mainly plays the roles of distributing, collecting and transmitting temperature signals and other channels.
At present, the nuclear power plant analog measuring instrument generally adopts a periodic verification method or a cross comparison method between multiple paths of redundant data to ensure the performance and the reliability of a sensor.
For the instrument adopting the regular checking and maintaining strategy, a large amount of workload needs to be consumed in the checking process, and the sensor state is found to be good by the checking result under most conditions. Meanwhile, the sensor is disassembled and assembled in the verification process, and the operations can damage the sensor or lead to errors of measured data of the sensor due to incorrect assembly. Due to the special position of a loop temperature sensor, operators can receive a large amount of radiation dose in the process of disassembly and assembly, and a large amount of radioactive waste can be generated.
For the instrument adopting the cross comparison maintenance strategy among multiple paths of redundant data, although the state evaluation can be carried out under the condition of not disassembling the sensor, the judgment is carried out only by using the data output by the sensor, and the state of the sensor cannot be judged in all directions. And an important instrument such as a primary circuit coolant temperature sensor cannot be accurately and comprehensively evaluated only by the output of the sensor. Meanwhile, the conventional cross comparison method only aims at a single reactor state, and the check of the primary loop temperature sensor is carried out under different reactor states.
