Description: Ulchin-1 is South Korea’s eighth nuclear power plant. Construction for Ulchin-1 began in January 1983 and the reactor began commercial operations in September 1988. Ulchin-1 is a three-loop pressurized light water reactor that was for the first time supplied by the French firm Framatome. As the supplier of the Ulchin-1 and -2 reactors, Framatome 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 content for the entire project including construction services provided by Korea Heavy Industries and Construction Corporation (Hanjung) and Dong Ah Construction Company.
Since entering commercial operations, Ulchin-1 shut down several times due to technical malfunctions. The first incident occurred one month after Ulchin-1 began commercial operations when a short circuit in the generator caused the reactor to be temporarily shut down. 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 addition, Ulchin-1 has experienced several incidents of coolant leaking from its steam generator tubes. In November 2003, the Korea Hydro and Nuclear Power Company announced plans to replace Ulchin-1’s steam generators and upgrade safety programs within the next five years.
