Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] In order to solve the problem that hydrogen is easy to accumulate in the steam generator compartment, the main coolant pump compartment, the pressurizer compartment and the pressurizer relief tank compartment in the prior art, causing deflagration and explosion, and then threatening the entire containment vessel. The main innovation of the present invention is to provide a kind of nuclear power plant containment, in the compartment of the steam generator compartment, the main coolant pump compartment, t...

Abstract

The invention relates to a containment vessel for a nuclear power plant. The containment vessel for the nuclear power plant comprises an explosion-proof compartment, wherein coolant spraying equipment for uniformly spraying coolant is arranged at the top of the explosion-proof compartment; holes for air inside and outside the compartment to circulate are formed in the wall of the explosion-proof compartment; a ventilation pipeline connected with a ventilation system of the containment vessel is arranged at the bottom of the explosion-proof compartment. According to the containment vessel for the nuclear power plant, on one hand, the hydrogen concentration is diluted by strengthening the ventilation, and one the other hand, the coolant is sprayed, so that detonation and explosion of hydrogen are prevented.

Description

technical field [0001] The invention relates to the technical field of nuclear power, more specifically, to a containment vessel of a nuclear power plant. Background technique [0002] The containment vessel in the field of nuclear power technology is the nuclear reactor containment vessel, or reactor containment vessel, containment vessel, which is the outermost building of a pressurized water reactor, including reactor pressure vessels, steam generators, main coolant pumps, and pressure regulators. And regulator pressure relief box, etc. The external wall structure of the containment shell is made of steel structure, reinforced concrete or prestressed concrete structure, which is used to control and limit the diffusion of radioactive substances from the reactor, so as to protect the public from the harm of radioactive substances. In case of rare accident conditions, The containment is the last barrier to prevent the release of fission products to the surroundings. [000...
