South Korea Plans Overhaul of Old Nuclear Reactor Equipment

South Korea is planning a sweeping overhaul equipment at its nuclear power plants in order prevent serious accidents and restore public confidence, the government announced Friday.
The plan, by the Ministry of Knowledge Economy, will check the operating systems of the country's nine reactors that have been operation for more than 20 years. Korea has 21 operational commercial reactors in total.
"All equipment and systems that could pose problems will be checked with a detailed plan for their replacement to be established in June," the ministry said. It added that inspectors also will check emergency power generators at the country's four nuclear power plants by July.
Parts will be purchased based on quality instead of the lowest price, the ministry added.
The plan comes after a 12-minute blackout at the Gori-1 unit in Busan, when outside electricity needed to keep the reactors cool was cut off by mistake during a routine safety check. The incident posed no threat, but caused problems when plant managers tried to cover up the ordeal.
In response, the ministry also said it will set up independent monitoring regimes involving civic groups and civilian experts.

"Enhancing transparency is vital for safe operations with related information to be shared with the general public," it said.
The four-pronged proposed safety package calls for tests, greater transparency in plant operations, higher capability and integrity of workers and contractors and open communication with residents and private watchdogs.
