Description: Ulchin-2 is South Korea’s ninth nuclear power plant. Construction for Ulchin-2 began in January 1983 and the reactor began commercial operations in September 1989. Ulchin-2 is the twin unit of Ulchin-1. The two reactors have identical designs and were constructed under the same contractual scheme during the second phase of South Korea’s nuclear energy development program. Framatome provided the reactors and agreed to transfer technology to Korean engineering and manufacturing companies. Alsthom supplied the turbine generators, and in collaboration with Framatome, supplied the steam generators and architectural engineering services. Korean firms contributed approximately 41.5 percent of the project’s contents including construction services provided by Korea Heavy Industries and Construction Corporation (Hanjung) and Dong Ah Construction Company.
Since entering commercial operations, Ulchin-2 shut down several times due to technical malfunctions. The first incident occurred several months after Ulchin-2 began commercial operations when low pressure fans in the turbine generator ruptured. In 1997 and 2001, Ulchin-1 and -2 were temporarily shut down several times due to swarms of shrimp and jellyfish clogging the inflow of water into the generators. In November 2003, the Korea Hydro and Nuclear Power Company announced plans to replace Ulchin-2’s steam generators and upgrade safety programs within the next five years.
