The South Korean labor ministry has ordered the closure of two nuclear reactors under construction, after a toxic gas leak killed three workers. The incident comes in the wake of cyberattacks and threats against the reactor’s operator.

Several government agencies and the police are conducting a probe
into the deaths at the construction site of the Ulsan nuclear
reactor on Friday.
"We will promptly conduct an investigation and hold
accountable those who are responsible (in the incident) if any
irregularities are discovered," the head of the Ulsan branch
of labor ministry, Yoo Han-bong, said on Saturday, according to South Korea’s
Yonhap news agency.
Korea Hydro and Nuclear Power Co., which runs the site where the
incident happened, says it suspects the deaths were caused by a
leak of nitrogen gas from an underground cable.
The two shut down reactors are New Gori No. 3 (99 percent
complete and awaiting commission in June) and New Gori No. 4 (98
percent complete and expected to become operational in 2016),
about 400 kilometers southeast of Seoul.
The accident comes as the state-run Korea Hydro and Nuclear Power
Co. (KHNP), operating the facilities, stays on high alert,
following a cyberattack on its computer system and threats of
“destruction” by hackers, claiming they can access
KHNP’s control systems.

reactors demanded closed by Christmas
Choi Hee-ye, a company spokeswoman, said there was no reason to
believe that Friday's accident was linked to the cyberattack
threats, AP reported.
Since mid-December, hackers have been making public blueprints,
manuals and other documents concerning KHNP, who run 23 nuclear
plants in South Korea.
They have voiced their demands and threats via a Twitter account
called: "President of anti-nuclear reactor group in
Hawaii."
They wanted three nuclear reactors shut starting Christmas, and
warned: “Residents near the reactors should stay away for the
next few months,” in case the demand was ignored.
South Korean prosecutors announced on Wednesday they had traced
internet addresses used by hackers to a Chinese town and asked
Beijing to help in the investigation.
An official close to the case told Reuters they weren’t ruling
out the involvement of North Korea, currently accused by the US of a cyberattack on Sony Pictures.
