NUREG published on high-burnup spent fuel storage and transportationNuclear NewsPower & OperationsNovember 25, 2020, 9:36AM|Nuclear News StaffA final report on the dry storage and transportation of high-burnup spent nuclear fuel (NUREG-2224) has been issued by the Nuclear Regulatory Commission. NUREG-2224 provides a technical basis in support of the NRC’s guidance on adequate fuel conditions as it pertains to hydride reorientation in the cladding of high-burnup spent fuel (over 45 gigawatt-day per metric ton uranium).NUREG-2224, “Dry Storage and Transportation of High Burnup Spent Nuclear Fuel,” was made publicly available on November 23 on the NRC’s ADAMS website with Accession No. ML20191A321.Sponsored results: Hydride reorientation is a process in which the orientation of hydrides precipitated in high-burnup fuel cladding during reactor operation changes from the circumferential-axial to the radial-axial direction. Because testing has shown that hydride reorientation can occur at temperatures and stresses lower than previously assumed, the NRC has since sponsored additional research to better understand whether the phenomenon could affect the mechanical behavior of spent fuel cladding and compromise the fuel when placed in dry storage and transportation containers. NUREG-2224 provides an engineering assessment of the results of that research.Tags:nrcnureg-2224snfspent nuclear fuelwaste managementShare:LinkedInTwitterFacebook

Chairman Svinicki announces she will resign on Jan. 20Chairman Kristine Svinicki announced today that she intends to leave the Nuclear Regulatory Commission on January 20. She issued a statement in a press release from the NRC.Chairman Svinicki has served as a commissioner under three administrations and is the longest serving member of the commission. She was first appointed to the commission by President Bush in 2007, was reappointed in 2012 by President Obama, and was designated chairman by President Donald J. Trump on January 23, 2017. Her term would have ended on June 30, 2022.Go to Article

Congress set to pass year-end funding billThe final text of the approximately 5,600-page Consolidated Appropriations Act 2021 was released on December 22. While the timing of final passage is still fluid, the Senate was expected to approve it and send it on to President Trump to sign into law, according to John Starkey, American Nuclear Society government relations director.Below are some key funding highlights from the legislation pertaining to nuclear energy.Go to Article
NRC withdraws LLW rule interpretationThe Nuclear Regulatory Commission has withdrawn a proposed interpretation of its low-level radioactive waste regulations that would have permitted licensees to dispose of waste by transferring it to persons who hold specific NRC exemptions. “The proposal is being withdrawn based on the NRC staff’s assessment that the proposed changes may not benefit the regulatory framework for the disposal of low-level radioactive waste,” the NRC said in a December 17 Federal Register notice.After releasing the proposed rule for public comment on March 6, 2020, the NRC received about 200 individual comment submissions and approximately 15,000 form letter submissions, the vast majority of which were in opposition to the proposed rule.“We have strongly disputed the argument by various groups who misrepresented the proposal as deregulation of radioactive waste disposal,” NRC spokesperson David McIntyre told the Courthouse News Service. “This would not have changed anything, just made an existing case-by-case approval process more efficient.”Go to Article
Texas congressman weighs in on Yucca MountainBurgessThe U.S. Congress has failed to uphold its promise to fully fund Yucca Mountain, in Nevada, as a permanent repository for spent nuclear fuel, Rep. Michael C. Burgess (R., Texas) writes in an op-ed article published on December 8 in the Dallas Morning News.More than three decades after passing the Nuclear Waste Policy Act, Congress has yet to fully fund the Yucca Mountain Project. Burgess points out that while some countries have found success with reprocessing spent fuels, the fission process will always produce some amount of material that must be safely disposed, making it necessary to find a permanent solution.Go to Article
NRC issues draft decommissioning guidance for commentThe Nuclear Regulatory Commission has issued the draft report, Consolidated Decommissioning Guidance, Characterization, Survey, and Determination of Radiological Criteria (NUREG-1757, Volume 2, Revision 2), with a request for comments by February 8.NUREG-1757, which is intended for use by applicants, licensees, and the NRC staff, was last updated in 2006. This latest revision addresses lessons learned and experience gained from the review of license termination plans, decommissioning plans, and final status surveys for licensees undergoing license termination since then.Notice of the draft NUREG was published in the December 8 Federal Register.Go to Article
Finland’s Onkalo repository a “game changer,” says IAEA’s GrossiOnkalo, Finland’s deep geologic repository for spent nuclear fuel, has been characterized as a game changer for the long-term sustainability of nuclear energy by Rafael Mariano Grossi, director general of the International Atomic Energy Agency.“Finland has had the determination to move forward with the project and to bring it to fruition,” Grossi said during a November 26 visit to Olkiluoto, Finland, where the repository is under construction. “Waste management has always been at the center of many debates about nuclear energy and the sustainability of nuclear activity around the world. Everybody knew of the idea of a geological repository for high-level radioactive nuclear waste, but Finland did it.”Posiva Oy, the Finnish company tasked with researching and creating a method for the permanent disposal of spent fuel from Finland’s Olkiluoto and Loviisa nuclear power plants, obtained a license to construct the Onkalo repository in 2015, marking the first time that a construction license for a geological disposal facility was issued anywhere in the world. The site near the Olkiluoto plant was chosen following several years of screening a number of potential sites.Go to Article
