Background
The containment vessel of the nuclear power station is a cylindrical prestressed reinforced concrete structure with a quasi-spherical dome and is the last barrier for preventing fission products from fuel and primary circuit radioactive substances from entering the environment. After the reactor has a Loss of Coolant Accident (LOCA), a large amount of radioactive and high-temperature and high-pressure steam-water mixture released can be contained and isolated by the containment vessel, so that damage to residents around the nuclear power station is prevented.
The steel lining is a layer of steel plate attached to the inner wall of the containment vessel and is an important guarantee for the containment vessel sealing performance. The steel lining is connected on the containment concrete structure by the rivet of welding on the steel lining, and the steel lining is better with the concrete laminating under the general condition, can not take place the hollowing phenomenon. However, due to the complicated construction technique and long construction period of the steel lining, and the contraction of the concrete in the containment vessel, the prestress tension construction process, and the like, the steel lining may be peeled off from the concrete structure, and the bulge phenomenon may occur. The bulge is the most common defect type of the steel lining, is unfavorable for the integrity of the containment, and the overlarge bulge has a serious influence on the safety of the third barrier of the nuclear safety and needs to be checked, recorded and tracked.
