3 SK nuke plant workers die in ‘gas leak’

THREE South Korean workers died yesterday after apparently inhaling toxic gas at a construction site for a nuclear plant being built by South Korea’s nuclear power company, which has come under recent threats by hackers, an official said.

The accident at the site in the city of Ulsan came as the state-run Korea Hydro and Nuclear Power Co was on high alert over a series of threats by hackers who claim they can disable the control systems of its plants.

Choi Hee-ye, a company spokeswoman, said there was no reason to believe that yesterday’s accident was linked to the cyber attack threats.

The victims were working at the construction site when they fell unconscious and were taken to a hospital, where they later died, Choi said.

The company has yet to determine the cause of the accident, although a nitrogen leak is suspected, she said.

Nitrogen is used at nuclear plants to reduce the oxygen levels in the cooling water to slow the oxidation of the equipment or to control pressure levels in tanks, according to Kim Sang-gyeong, a Korea Hydro spokesman.

Last week, documents including layouts of nuclear facilities and personal data of workers were published online.

Media said the images were posted by hackers.
