Severe radiation risk at Fukushima’s nuclear reactor Unit 4

Concerns focus on Fukushima unit stability TOKYO, May 23 (UPI) — Whether a pool where spent fuel is stored at Japan’s Fukushima nuclear plant could withstand another strong earthquake has become a source of growing concern.

The concerns among activists, experts and politicians focus on Unit 4, which contains most of the plant’s spent fuel not stored in dry, hardened storage casks, Stars and Stripes reported Wednesday.

After the 9-magnitude earthquake and tsunami, an investigative report by the Rebuild Japan Initiative Foundation, an independent think tank started to investigate the causes of the plant disaster, cited among risks a loss of cooling water in Unit 4.

If left exposed, the spent fuel could heat and melt, releasing a huge amount of radiation.

The plant’s operator, Tokyo Electric Power Co., has said on its Web site Unit 4 is sound and the building could withstand an earthquake of the magnitude of the March 11, 2011, temblor.

But public trust in Tepco remains low, Stars and Stripes said, and calls for more efforts to empty and secure Unit 4 continue in Japan and beyond…… http://www.upi.com/Top_News/World-News/2012/05/23/Concerns-focus-on-Fukushima-unit-stability/UPI-67051337797686/#ixzz1vpwgvulJ
