Fifth nuclear reactor in Korea shuts down due to control rod issue

Korea Hydro and Nuclear Power (KHNP) shut down one of the nuclear reactors at the Hanul power plant because of a control rod problem.

The 950-MW Hanul Unit 1 reactor was taken offline Monday, according to the South China Morning Post. Workers are investigating the cause of the control rod issues and did not say when the reactor will be restarted. The plant’s other five reactors continue to run at full power.

That brings to five the number of reactors offline in the country just before peak summer demand, but KHNP said in the article that the latest shutdown would have little impact on supply. Three are down for scheduled maintenance and one is awaiting a license extension. The country generates about a third of its electricity from a total of 23 reactors.
