- World must act to stop Fukushima nuclear discharge (China Daily, Oct 5, 2013):
The devastating earthquake in northeastern Japan two years ago caused a nuclear leak at Fukushima Daiichi Nuclear Power Station. In July 2012, Alaskan seals exhibited inexplicable hemorrhage phenomena and signs of immunity deficiency. Scientists suspected the condition had something to do with Japan’s discharge of nuclear sewage, or radioactive water, into the Pacific Ocean. However, no evidence has yet confirmed that suspicion. The Japanese government has proposed to take measures to clean up the post-disaster nuclear waste by the end of March 2014. To this point, they have been simply dumping it into the sea.
On Aug 7, 2013, Japan’s Nuclear Disaster Countermeasures Headquarters said the daily discharge into the sea was nearly 300 tons. Research analysis shows that underground water is polluted and therefore radioactive discharge cannot be avoided. Currently, the Japanese government and Tokyo Electric Power Company (TEPCO) are considering pumping underground water into the area to reduce the discharge. By September 2014, the volume of pumped sewage will be 40,000 tons.
Estimates show that the daily outflow of underground water around Fukushima’s four nuclear units is 1,000 tons, of which 400 tons flows under the reactors. Of the other 600 tons, 300 tons flows through tunnels between the plants, polluted by the highly concentrated sewage, and then flows into the sea. The remaining 300 tons runs into the sea without pollution. TEPCO is trying to prevent more polluted water reaching the sea, via a new relief project, to reduce daily discharge to 60 tons.
