Abstract

The invention relates to the technical field of nuclear safety and nuclear system detection, in particular to a pressurized water reactor nuclear power station primary circuit total gas content measuring device which comprises a shielding protective cover, and a sampling assembly and a sample measuring assembly which are detachably connected with the shielding protective cover. The sampling assembly comprises a sampling bottle; a valve I connected with a bottle opening of the sampling bottle through a pipeline; a valve II connected with the other bottle opening of the sampling bottle through apipeline; a first quick female joint connected with the valve I through a pipeline; a second quick female joint connected with the valve II through a pipeline; and a balance pipeline, wherein one endof the balance pipeline is connected with the pipeline located between the valve I and the first quick female joint, and the other end of the balance pipeline is connected with the pipeline located between the valve II and the second quick female joint. The total gas content measuring device is convenient to disassemble and assemble, convenient to carry, capable of rapidly sampling and accuratelymeasuring the total gas content of the primary loop, and can be effectively used for detecting the gas content of the coolant in the primary loop.

Description

technical field [0001] The invention relates to the technical field of nuclear safety and nuclear system detection, in particular to a device for measuring the total gas content of a primary circuit of a pressurized water reactor nuclear power plant. Background technique [0002] Nuclear power is one of the three pillars of electric power in the world today. At present, there are more than 400 nuclear power units in operation in more than 30 countries and regions in the world, with a total capacity of more than 300 million kilowatts; there are many types of nuclear power, such as AP1000, CPR1000, CNP1000 , ACP1000, CAP1000, etc. Among them, the pressurized water reactor nuclear power plant uses the main pump of the primary circuit to transport the reactor coolant, so that it can complete the circulation among the core, the coolant loop, and the steam generator, realize the heat transfer on the primary side, and also have the function of ensuring the safety of the core , is ...
