Abstract

The invention provides a nuclear power plant post-accident containment heat leading-out system, which comprises a plurality of soaking bodies arranged on the inner wall of the safe containment at thevertical middle section of a ventilation channel and each provided with a mist outlet and contains water inside, and a plurality of groups of semi-immersed ultrasonic oscillators, wherein each group of semi-immersed ultrasonic oscillators corresponds to one soaking body and coated by the corresponding soaking body, and the semi-immersed ultrasonic oscillators are used for atomizing water from thecorresponding soaking bodies. According to the heat leading-out system disclosed by the invention, the safe containment obtains higher heat leading-out power through feeding and direct evaporation ofmicro-droplets generated by the semi-submerged ultrasonic oscillator in the natural ventilation channel.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a containment heat export system after a nuclear power plant accident. Background technique [0002] The airtight containment is an important barrier to prevent the leakage of radioactive materials in the event of an accident in a nuclear power plant. Normally, after an accident, the containment vessel will be isolated and become a closed space, and the sharply increased temperature and pressure are all borne by the containment vessel structure. This design requires the containment vessel to have a large free volume and shell thickness, and also requires the matching post-accident containment depressurization and heat removal system to have high performance. [0003] After the accident, the core problem of the airtight containment of a nuclear power plant is the export of reactor waste heat. If the waste heat export mechanism is lost, the temperature and pressure in...
