Fukushima nuclear accident is ‘wake-up call’ for US to improve monitoring of spent fuel pools

by National Academies of Sciences, Engineering, and Medicine
Published by EurekAlert! on 20 May 2016

The Phase 2 report from the National Academies focuses on three issues: (1) lessons learned from the accident for nuclear plant security, (2) lessons learned for spent fuel storage, and (3) reevaluation of conclusions from previous Academies studies on spent fuel storage.

The 2011 Fukushima Daiichi nuclear accident should serve as a wake-up call to nuclear plant operators and regulators on the critical importance of measuring, maintaining, and restoring cooling in spent fuel pools during severe accidents and terrorist attacks, says a new report from the National Academies of Sciences, Engineering, and Medicine. This report is the second and final phase of a congressionally mandated study on what lessons can be learned from the Fukushima Daiichi nuclear accident. The report from Phase 1 of this study was released in July 2014. The Phase 2 report provides findings and recommendations for improving U.S. nuclear plant security and spent fuel storage as well as re-evaluates conclusions from previous Academies studies on spent fuel storage safety and security.

Radiation and food safety: A story of standards

April 26th marked the 30th anniversary of the 1986 Chernobyl nuclear disaster. The ~2600 sq km (~1000 sq mi) exclusion zone remains in place around the power plant and wildlife are reclaiming the habitat. Just outside the exclusion zone, the Associated Press reports that dairy farms are operating and selling milk and dairy products around Belarus and Russia. The author obtained a milk sample from one of these farms, had it tested, and found it to be contaminated with levels of strontium-90 (90Sr) that are 10 times higher than the nation’s food safety limits. At first I was alarmed that this could make it to market, however, since working for the InFORM project I’ve learned that not all limits are equal. Let’s take a gander at how this milk would fare under standards from around the world.

Screening effect? Examining thyroid cancers found in Fukushima children

In Iwaki, a town south of the Fukushima nuclear plant, a doctor conducts a thyroid examination on 4-year-old Maria Sakamoto. Scientists are puzzled over a high number of thyroid abnormalities observed so soon after the accident.

Mystery cancers are cropping up in children in aftermath of Fukushima

The March 2011 meltdowns at the Fukushima Daiichi Nuclear Power Plant caused extensive human suffering—evacuations, emotional trauma and premature deaths, disrupted jobs and schooling. What they have not caused, so far, is radiation-related illness among the general public, and few specialists expect dramatic increases in cancers or other ailments. The reactors spewed just a tenth of the radiation emitted by the Chernobyl disaster, winds blew much of that out to sea, and evacuations were swift. Yet one wave of illness has been linked to the disaster—the ironic result of a well-intentioned screening program. Continue reading Screening effect?

With Fukushima’s fifth anniversary approaching, we can probably start to relax about radioactive seafood

Fisherman from the “Kiyomaru” fishing boat pull in their net as they sail off the Iwaki town south of crippled Daiichi nuclear power plant, Fukushima prefecture September 20, 2013. Only a small part of the boat’s catch will be used to test for radioactive contamination in the waters near the Fukushima Daiichi nuclear facility, while the rest will be thrown back into the ocean.

March 11 will mark the five-year anniversary of the Fukushima Daiichi disaster, a series of nuclear meltdowns, triggered by a devastating earthquake-induced tsunami, that released massive amounts of radioactive material and resulted in the largest nuclear disaster since Chernobyl. Since then, the plant’s damaged drainage system has continued to leak radioactive water into the environment, and one of the biggest enduring public concerns has been the safety of fish caught in the area’s surrounding waters.

Screening truffles for radioactivity 30 years from Chernobyl

Some forest mushrooms, such as wild porcini, can accumulate dangerous levels of radioactivity from the soils they grow in. But until now it was unclear if the same was true for truffles, fungi that range among the most expensive foods in the world. Swiss and German researchers have analysed Burgundy truffles collected in central Europe and found they contain only negligible amounts of radioactive caesium, being safe for consumption. The results are published today (25 February) in Biogeosciences, an open access journal of the European Geosciences Union (EGU).
