If this early hot weather is any indication this summer will suck a lot of energy out of the nation's power grid
So the government and the nuclear energy industry are taking pre-emptive steps to prevent power shortages.
The nation's nuclear power plants have been undergoing a special inspection this month separate from regular check-ups.
Last summer, several nuclear reactors went offline either due to regular inspections or because they were found to have used parts with forged safety certificates.
That led to voluntary power cutbacks during a prolonged heat wave.
Korea has a total of 23 nuclear reactors which provide around one-third of the nation's total energy supply.
