Two South Korean nuclear power reactors have been shut down following apparently unrelated malfunctions. Officials say there is no danger of a radiation leak.

South Korean nuclear operators say the Shingori-1 reactor, near the city of Busan, was shut down early Tuesday following a control rod malfunction.

A short time later, the number 5 reactor at the Yeonggwang facility, 260 kilometers south of Seoul, also suffered what officials say appears to be an unrelated malfunction.

South Korea depends on atomic plants to generate more than one-third of its electricity. The resource-poor country has vowed to push forward with nuclear power, despite last year's nuclear disaster in Japan.

Its 23 nuclear power reactors have been under increased scrutiny since the reactor meltdown at the Fukushima power plant, which was triggered by a massive earthquake and tsunami.
