安全壳降压系统、反应堆厂房及安全壳降压方法
By installing a hot water exchange tank and an exhaust piping system inside the containment vessel, and using cooling water to remove substances from the radioactive gas, the problem of pressure exceeding the design pressure inside the containment vessel was solved. This achieved effective pressure relief of the containment vessel and retention of radioactive materials, simplified the system structure, and reduced costs.

AI Technical Summary
In existing technologies, the pressure of radioactive gases inside the containment may exceed the design pressure, leading to containment accidents. Existing pressure relief systems are complex in structure and expensive.
A hot water exchange tank and an outlet pipeline system are used to introduce radioactive gases from inside the containment vessel into the cooling water of the hot water exchange tank. Gas-liquid separation is performed through a flow guide hood, and radioactive materials are removed using the cooling water. The depressurization process is automatically controlled by a control component.
It achieved effective depressurization of the containment vessel, reduced the emission of radioactive materials, simplified the system structure, and lowered construction and maintenance costs.
