Abstract

The invention discloses an equipment leakage detection experiment system and method under pressure environment maintenance condition. The equipment leakage detection experiment system comprises a water replenishment system, a water storage system, a water level maintenance system and a heating experiment device, wherein the water replenishment system is connected with the water storage system through a water replenishment pipeline, so as to replenish water for the water storage system; the water storage system is connected with the water level maintenance system through a water delivery pipeline, so as to remain the water level unchanged; an adjusting valve and a flowmeter are arranged on the water delivery pipeline; the water level maintenance system is connected with the heating experiment device through a communication pipeline, so as to supply water stably; a communication stop valve is arranged on the communication pipeline; the heating experiment device comprises a pressing experiment container; a heating part is arranged in the pressing experiment container; a pressure transmitter is arranged at an inlet position of the pressing experiment container to monitor a pressure value of the heating part in real time; a discharge pipeline is arranged at an outlet position of the pressing experiment container; a discharge stop valve is arranged at the end of the discharge pipeline; a pipeline inclined upward is arranged at the tail end of the discharge pipeline, and the range of the inclination angle is 20-60 degrees.

Description

technical field [0001] The invention relates to the field of nuclear equipment experiments, in particular to an equipment leakage detection experimental system and method under pressure environment maintenance conditions. Background technique [0002] Comparing the three serious accidents that have occurred in the world, it can be found that keeping the core melt in the pressure vessel and ensuring the integrity of the reactor pressure vessel can greatly alleviate the further development and deterioration of the severe accident. On the basis of digesting and absorbing the internal retention strategy of the existing advanced reactor melt, CNNC proposed to set up a reactor cavity water injection cooling system to cool the lower head of the pressure vessel in two ways, active and passive, to contain the core melt. In the lower chamber of the pressure vessel, the integrity of the pressure vessel is maintained. Therefore, the flow and heat transfer characteristics of the outer s...
