Construction of Air Tightness Test System of Pressurized Water Reactor Containment

Abstract

The containment vessel, also known as the "nuclear reactor containment vessel", is the building forming the outermost peripheral pressurized water reactor, which controls and limits the diffusion of radioactive substances from the reactor to protect the public from radioactive substances. Therefore, it is necessary to test and verify the air tightness of the reactor envelope structure. Under the same test condition (differential pressure), the leakage per unit size of a single leakage source is considered the same as the actual engineering. Based on the relevant standards, the paper selects the equipment, builds the experimental platform, and conducts the simulation test with the scale scale model, laying the foundation for the establishment of the actual engineering.
