Abstract

The invention provides a containment filtration and exhaust system of a nuclear power plant. The containment filtration and exhaust system comprises a spent fuel tank, a containment isolation valve, apipeline and an exhaust bubbler; a gas inlet of the pipeline penetrates into the containment of the nuclear power plant; an exhaust port of the pipeline is inserted into the spent fuel tank; the exhaust bubbler is arranged at the exhaust port of the pipeline; and the containment isolation valve is arranged on the pipeline and is used for opening or closing the pipeline. The system is simple in process and flexible in arrangement, and the existing spent fuel tank of the pressurized water reactor nuclear power plant is utilized, arrangement of a complicated special system or equipment is not needed, manufacturing cost is low, and operation is simple.

Description

technical field [0001] The invention relates to a nuclear power plant containment filter exhaust system. Background technique [0002] After a severe accident in a nuclear power plant, the containment vessel may be at risk of overpressure. [0003] At present, in response to this requirement, the usual system design is: set up a special filtration system outside the containment, based on special devices such as sand bed filters, metal filters or wet scrubbing filters, after filtering the radioactive gases drawn out of the containment emission. [0004] Therefore, how to provide a nuclear power plant containment filter exhaust with simple system flow, flexible layout, which can utilize the existing spent fuel pool of the PWR nuclear power plant, without the need to set up complex special systems and equipment, low cost, and simple operation and operation The system becomes an urgent problem to be solved. Contents of the invention [0005] The present invention aims at th...
