Additional faults have been detected in the No. 4 reactor at a nuclear power plant in Uljin, which has been undergoing repairs, and a complete shutdown now seems inevitable. This will add to strain on the power grid this summer after reserve levels fell to alarming levels.
Korea Hydro & Nuclear Power 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.
Experts warn that if one or two power plants stop operating due to faults and summer temperatures suddenly soar amid ever-increasing energy demand, Korea could face a power emergency.
