S. Korea Raises Tsunami Walls to Quell Unease About Atomic Risks

South Korea said it will double the height of sea walls protecting its oldest nuclear reactor to quell unease about the risks of atomic power, drawing on the lessons of the Fukushima disaster in Japan.

“Who could have imagined a worst-case scenario like Fukushima,” said Chang Soon Heung, a nuclear scientist at the Korea Advanced Institute of Science and Technology, who advised the government on safety after radiation leaks in Japan. “We couldn’t remain satisfied with current requirements. Citizens’ expectations for safety standards are high.”
