Test system and test method for performance evaluation of active equipment in accident environment

Abstract

The invention discloses a test system and a test method for performance evaluation of active equipment in an accident environment. loop, the main loop, switching loop, and active equipment are connected in series, the main loop is used to simulate the pressure difference and temperature difference of the loop, and the switching loop is used to detect the action switching capability of the active equipment. After the loss of water accident environment is established in the environmental chamber, the active equipment that has been on standby overcomes the pressure difference and temperature difference of the circuit to start work and run stably, and verify the safety-related active equipment. Ensure the ability to start the auxiliary safety system; through the switching circuit, the switching action capability of the active equipment can be tested to verify whether the auxiliary safety system is working normally after the loss of water accident to prevent the core from melting.

Description

technical field [0001] The invention relates to the technical field of nuclear-level equipment testing, in particular to a test system and a test method for performance evaluation of active equipment under an accident environment. Background technique [0002] Auxiliary safety systems such as waste heat removal systems and safety injection systems are installed in nuclear power plants to improve safety. When the primary circuit system ruptures or the main steam pipe ruptures and a loss of water accident occurs, these safety systems are activated, and the safety system injects water into the core or the primary circuit to prevent melting and maintain the integrity of the core. As the active equipment that injects coolant into the core under the loss of water accident environment (LOCA), the working performance and reliability of the active equipment under LOCA conditions determine the safety level of the entire nuclear power plant. [0003] According to the setting requireme...
