Two South Korea Nuclear Reactors Shut Down

Two South Korea Nuclear Reactors Shut Down

With six mammoth pressurized water reactors on this site, with power outputs ranging from 947 to 997 MWe, Yeonggwang is the third-largest nuclear locale in the world

Two South Korean 1,000-megawatt nuclear reactors have been shut down at separate plants, both as a result of unrelated systems malfunctions.

The state-run Korea Hydro and Nuclear Power (KHNP) says there is no apparent danger of a radiation leak at either reactor – at Yeonggwang on the southwest coast and Shingori on the southeast coast.

“There is no correlation between the two incidents,” a KHNP spokesman told AFP on Tuesday.

The Shingori reactor, near the city of Busan, was shut down after a warning signal at 8:10am (0910 AEST).

“There was a malfunction in the reactor’s control rod, but the reactor is now stable with no danger of a radiation leak,” the spokesman said.

It is the first time the reactor has been shut down since it began operations in February last year.

South Korea operates 23 nuclear power plants which meet more than 35 per cent of the country’s electricity needs.

The other incident at the Yeonggwang plant saw an automatic reactor shutdown following the malfunction of a water supply pump, the spokesman said.

In July, a different 1,000-megawatt reactor at Yeonggwang – some 260km south of Seoul – went into automatic shutdown after a malfunction.

The South Korean government has vowed to stick to its nuclear power program despite last year’s nuclear disaster in Japan.

Doubts over safety standards were fuelled in May when five senior engineers were charged with trying to cover up a potentially dangerous power failure at South Korea’s oldest nuclear plant.

The five, including a 55-year-old chief engineer at the Gori-1 reactor, were accused of violating a law on nuclear safety.

The reactor, built in 1978 near the southern city of Busan, briefly lost mains power on February 9 and the emergency generator failed to kick in. The power cut caused cooling water to stop circulating.
