Radioactive waste tank leaking at Washington state's Hanford nuclear reservation The tanks at the nation's most contaminated nuclear site hold millions of gallons of radioactive material left over from nuclear weapons production decades ago Saturday, February 16, 2013, 11:55 AM OLYMPIA, Wash. — The long-delayed cleanup of the nation’s most contaminated nuclear site became the subject of more bad news Friday, when Washington Gov. Jay Inslee announced that a radioactive waste tank there is leaking. The news raises concerns about the integrity of similar tanks at south-central Washington’s Hanford nuclear reservation and puts added pressure on the federal government to resolve construction problems with the plant being built to alleviate environmental and safety risks from the waste. The tanks, which are already long past their intended 20-year life span, hold millions of gallons of a highly radioactive stew left from decades of plutonium production for nuclear weapons. more: www.nydailynews.com/news/national/hanford-nuclear-tank-wash-leaking-liquids-article-1.1265932

Thousands of nuclear waste containers must be re-opened in Sweden 09 May 2013 Over 7,000 containers of radioactive waste have to be taken out of storage since they contain too much mercury and other liquids, reports Swedish Radio’s science programme. The nuclear waste company SVAFO says that they cannot send this contaminated waste on to their usual underground bunkers, and will have to spend hundreds of millions to build a special facility to open the containers and deal with the waste. Another 2844 similar containers have already been sent underground to their final resting place 50 metres under the sea. They will have to be taken out and investigated.

Vitrification: high-level radioactive waste (HLW), University of Sheffield waste products from refining metal ore news.discovery.com/tech/videos/the-new-solution-to-our-nuclear-waste-problem-video.htmNew Research Suggests Nuclear Waste Could Be Reduced 90%Researchers from the University of Sheffield’s Faculty of Engineering have developed a method which would significantly reduce the volume of nuclear waste, by up to 85-95%. Not only would it reduce the volume, but the end product would also effectively lock in the radioactive plutonium, creating a stable end product, a much more appealing proposition than current radioactive end results. The researchers have developed a method that would mix plutonium-contaminated waste with blast furnace slag to create glass, locking away the radioactive material and reducing nuclear waste volume by over 80%. This is a much more attractive option compared to current method of containing the radioactive material in copious measures of concrete, which in turn increases the overall volume of waste products. cleantechnica.com/2013/11/12/new-research-suggests-nuclear-waste-reduce-90/6 November 2013 Volume of nuclear waste could be reduced by 90 per cent says new research www.sheffield.ac.uk/news/nr/nuclear-research-sheffield-university-fukushima-1.324913
