28 October 2002 – The operation of the Uljin No. 1 nuclear reactor in South Korea’s North Gyeongsang Province has been suspended twice within a week due to problems with an atomic power generator incorporated in the reactor, the Ministry of Science and Technology said Monday.
The accidents took place Oct. 20 and 26 when a protective relay for power transmitter and the generator stopped automatically. Both were classified as zero grade, meaning they have no impact on nuclear security according to standards set by the International Atomic Energy Agency (IAEA).
However, the accidents are causing considerable controversy over nuclear reactor inspection systems and their security. “When the ministry looked into the reactor in question Oct. 20, specialists said they did not find problems in the nuclear reactor, but they found problems in the generator Oct. 26,” a ministry source said. The source said the ministry has asked the supplier to replace the generator with a new one.
