Cracks in nuclear facility add to South Korea’s nuclear scandal problem

Cracks at South Korean nuclear plant raise fresh safety concerns By K.J. Kwon, CNN November 9, 2012 Seoul, South Korea (CNN) –– Tiny cracks have been found in tunnels at a nuclear plant in South Korea, increasing concerns about nuclear safety in the country following a recentscandal involving the use of unverified parts.
The reactor where the cracks were found will remain offline for weeks as regulators investigate the problem, putting extra strain on South Korea’s already stretched power supply going into the winter months…… the news could hurt South Korea’s efforts to export its
nuclear power technology to other countries.
The problems at the South Korean reactors come amid increased scrutiny of nuclear power worldwide following the crisis at the Fukushima Daiichi nuclear plant in Japan during the aftermath of the earthquake and tsunami that hit the country in March 2011.

Seoul restarts aged nuclear reactor despite safety concerns

 Korea Times, 7 Aug 12 The government decided Monday to restart an aged nuclear reactor that recently underwent months-long scrutiny over its safety, amid looming signs of a power shortage due to a record heat wave.

Operation of the Reactor-1 at Gori Nuclear Power Plant in Busan was
resumed earlier in the day with the reactor expected to reach its full
generation capacity on Friday, according to the Ministry of Knowledge
Economy….. The 578-megawatt reactor, located some 450 kilometers
southeast of Seoul, was manually shut down on March 12 after the Hydro
& Nuclear Power Co. belatedly reported a major safety breach during a
regular maintenance check the previous month, when the reactor, along
with its backup generator, temporarily lost power….. the reactor had
remained shut down amid widespread public concerns over safety of the
reactor whose initial 30-year lifespan ran out but was extended by 10
years in 2008….

Concern growing about poor safety of South Korea’s nuclear reactors

Nuclear reactor shut down for safety reasons, Aug.1,2012 Incident at Younggwang plant the latest in a long string of nuclear troubles, The Hanyoreh, By Noh Hyung-woong, staff reporter Reactor 6 at Younggwang Nuclear Power Plant in South Jeolla province was shut down again on July 30 due to a malfunctioning reactor rod….

The repeated problems with Younggwang reactor 6 have residents in the area nervous. Reactor 6 first broke down during a 2002 trial run. Since then, it has gone out of action 9 times in past 10 years.
Among those cases, some were trivial, due to lightning strikes and a mistake on operation. But in Dec. 2008, the reactor was stopped because warning signals appeared, indicating the reactor rod was in the wrong position.
Yang-yi Won-young director of Common Action for Nuke Free Society said, “The reactor rod is the last line of defense against a serious accident. It was fortunate that the reactor was shut down in time. If it hadn‘t been, it would have created a terrible disaster.”
Some brought up the problem of Korean-style pressurized light water reactors, citing their frequent breakdowns. “The reactors that recently broke down, including reactor 6 at the Younggwang plant, are localized as Korean style,” said Professor Suh Kune-yull at the
Nuclear Engineering Dept. of Seoul National University. “It seems that their electronic circuits and other components fail frequently.”…..
more and more people raised the questions of the safety of nuclear power plants. In particular, the Younggwang accident happened while MKE has been moving to restart Kori Nuclear reactor No.1…… http://english.hani.co.kr/arti/english_edition/e_business/545178.html

Damaged South Korean nuclear reactor to shut down for 2 years

Uljin Nuclear Reactor Faces 2-Year Shutdown The Chosunilbo, 10 May 12, Additional faults have been detected in the No. 4 reactor at the Uljin Nuclear Power Plant, which has been undergoing repairs, and a complete shutdown now seems inevitable……..

Korea Hydro and Nuclear Power Corporation has found that damage in the No. 4 reactor, where operations were halted due to defects in the machine that condensates steam from the turbine, is more serious than expected and tentatively decided to replace the steam generator.

Replacing it will take one or two years, so the reactor will not operate until at least next summer. It generates 1 million kW, or the capacity of two thermal power stations. …
