Electric heating element deformation detecting control system

Abstract

The invention relates to an electric heating element deformation detecting control system which comprises a water circulation system control unit, a heat shielding system control unit, a radiation monitoring system control unit, a thermal measurement system monitoring unit and an interlock control unit. The water circulation system control unit is used for controlling water filling, drainage and cleaning of a water circulation system and carrying out heating and temperature control on loop water. The heat shielding system control unit is used to control the valve of a heat shielding system. The radiation monitoring system control unit is used for sampling and measuring gamma dose in the water circulation system and nuclides in a water sample, and then determining the damage condition of afuel assembly through comprehensive calculation. The thermal measurement system monitoring unit is used to monitor the flow, pressure, temperature and liquid level parameters of a thermal system in real time. The system provided by the invention continuously measures the gamma dose of the water circulation system, detects radionuclides in the nuclide analysis of the water sample and comprehensively calculates a detection value to determine whether the fuel assembly is damaged.

Description

technical field [0001] The invention relates to the technical field of electric heating element deformation inspection, in particular to a detection and control system for electric heating element deformation. Background technique [0002] The electric heating element deformation inspection equipment is an important special tool for the replacement and maintenance of the electric heating element of the voltage stabilizer. It is used to check the surface damage of the electric heating element inside the voltage stabilizer. The electric heating element is installed at the lower part of the voltage stabilizer, which is prone to swelling and rupture after long-term use. Therefore, it is necessary to check the deformation of the electric heating element. Since the inside of the voltage stabilizer has certain radioactivity (not less than 50mSv / h), the current electric heating Component deformation inspection cannot reliably detect the deformation of the electric heating element un...

The electric heating element is installed at the lower part of the voltage stabilizer, which is prone to swelling and rupture after long-term use. Therefore, it is necessary to check the deformation of the electric heating element. Since the inside of the voltage stabilizer has certain radioactivity (not less than 50mSv / h), the current electric heating Component deformation inspection cannot reliably detect the deformation of the electric heating element under the condition of isolating radioactive contamination and ensuring the safety of the testing personnel, which has resulted in the urgent need for reliable testing of the electric heating element and the contradictory status quo to ensure the safety of the testing personnel
