Korea Hydro and Nuclear Power spokesman told The Times of India that the nuclear reactor was closed by due to a control rod problem
South Korea’s nuclear watchdog said the thorough checks have been carried out at the 950-MW Hanul No.1 reactor in Uljin County, over 300km southeast of Seoul and that the facility was safe.

The restart comes at the peak time for electricity demand in the nation.

Last month, the government said it would provide stable power this summer using new generating capacity and fewer closed nuclear power plants.

The country faced nuclear safety scandal that prompted the closure of some reactors in 2012.
