Abstract

The invention discloses a steel containment energy control system. The steel containment energy control system comprises a suppression pool, a submerging pool and at least one head water tank, wherein the suppression pool is arranged in a containment and communicated with the internal space of the containment; the suppression pool is filled with cooling water for suppressing the rise of pressure in the containment; the containment is held in the submerging pool; the head water tank is arranged above the submerging pool and communicated with the submerging pool; the head water tank is used for injecting cooling water into the submerging pool; the submerging pool is used for guiding heat in the containment into the air space. In the case of an accident, the mixture of steam and air in the containment goes into the suppression pool due to differential pressure and is cooled, and therefore, the rise of pressure in the containment is quickly suppressed; the steam in the containment is condensed on the inner wall of the containment, heat is transferred to the cooling water outside the containment via the wall of the containment, and the heat is discharged to the final hot trap of the air space by consuming water. The heat in a reactor core and the containment can be discharged in a completely passive way in the whole process after the accident.

Description

technical field [0001] The invention relates to the field of nuclear power plant safety equipment, in particular to a passive steel containment energy control system. Background technique [0002] The use of nuclear power is a major breakthrough in the history of human energy utilization. The use of nuclear fission reactions can produce high energy output unmatched by all other traditional fossil energy sources, and these high energy outputs often only need to consume a small amount of nuclear fuel. The characteristics of low input and high output make mankind pay more and more attention to the utilization of nuclear energy, and continuously increase the research and development in the field of nuclear energy. Today, nuclear energy has become an important energy component in many countries in the world. However, while nuclear power has extremely high utilization value, it may also bring great harm. In the process of utilizing nuclear power, if improper protection leads to ma...
