The Nuclear Safety and Security Commission said on the 28th that it allowed criticality of Shin-Kori Unit 2, which has been undergoing a regular inspection since Oct. 25.
Criticality refers to a state in which the nuclear fuel's fission reaction continues so that a nuclear power plant can reach normal output. Allowing criticality means allowing normal operation of the plant.
The Nuclear Safety and Security Commission said, "As a result of inspecting 80 items that must be completed before criticality out of a total of 91 items in this regular inspection, we confirmed that the reactor can achieve criticality safely going forward."
In this regular inspection, the Nuclear Safety and Security Commission checked the attached anchors of the primary component cooling seawater system and confirmed that all meet performance requirements, and confirmed that the fire protection barriers for conduits inside the reactor containment building and other areas comply with the relevant technical standards.
The attached anchors were approved for use after performance testing, and this regular inspection reconfirmed the performance of the anchors already installed.
The Nuclear Safety and Security Commission plans to carry out 11 follow-up inspections, including a power ascension test, to make a final confirmation of safety.
