New Mexico has passed legislation aimed at preventing Holtec International from constructing and operating a consolidated interim storage facility (CISF) for spent nuclear fuel in the state. On March 17, hours after being passed by the New Mexico House on a 35-28 vote, Democratic Gov. Michelle Lujan Grisham signed SB 53, which prohibits the storage and disposal of radioactive waste in New Mexico without the state’s consent.

Nuclear dismantling and decommissioning company APTIM said it is on schedule to wrap up field activities decommissioning the U.S. Navy’s Surface Ship Support Barge (SSSB) by April, with project closure slated for June. The company announced yesterday that its team has completed the demolition of the barge’s former spent fuel water pool, also referred to as the “wet pit,” or the heart of the vessel.

When it comes to managing nuclear waste, technology is transforming the way some of the most problematic waste is handled. The idea to transform nuclear waste into glass was developed back in the 1970s as a way to lock away the waste’s radioactive elements and prevent them from escaping. For more than 40 years, vitrification has been used for the immobilization of high-level radioactive waste in many countries around the world, including the United States.

The second of three machines that will be used to safely remove waste from the Magnox Swarf Storage Silo at the Sellafield nuclear site in the United Kingdom has successfully been assembled, it was announced by Sellafield Ltd., a subsidiary of the U.K. government’s Nuclear Decommissioning Authority.
A video showing how waste is removed and the Magnox Swarf Storage Silo prepared for decommissioning has been posted to YouTube and can be found here.

The Department of Energy has announced that tank operations contractor Washington River Protection Solutions (WRPS) and subcontractor Atkins are making progress at the Hanford Site in Washington state in their preparations to provide replacement melters to treat radioactive and chemical tank waste for the site’s Direct-Feed Low-Activity Waste program.

New legislation that would require the cleanup of Jana Elementary School in suburban St. Louis was introduced in the Senate by Sen. Josh Hawley (R., Mo.). The Justice for Jana Elementary Act would also order the United States Army Corps of Engineers (USACE) to test all properties in the Hazelwood School District, of which Jana Elementary is a part.

The Nuclear Regulatory Commission announced that it has released the site of the La Crosse boiling water reactor in Wisconsin for unrestricted public use. The action comes after the NRC found that EnergySolutions subsidiary LaCrosseSolutions had met the agency’s radiation protection standards in decommissioning the nuclear power plant.

Used nuclear fuel and high-level radioactive wastes are by-products of nuclear energy production and other applications of nuclear technology, and the consensus approach to disposing of those wastes safely is to encapsulate them and emplace them in stable geologic formations (geologic repositories) where they will be isolated from people and the environment for very long periods of time. The federal government has established environmental standards for waste isolation that any proposed geologic repository must meet.
In July 2021, the American Nuclear Society established a special committee to consider possibilities for revised generic environmental standards for disposal of spent nuclear fuel and high-level radioactive waste in the United States. The committee developed a number of recommendations, which are contained in a draft report that was to be issued in February for review and comment by stakeholders. The draft report can be found on the ANS website, at ans.org/policy/repositorystandard/.
The committee’s draft recommendations are based on two underlying assumptions. First, that the relevant legislative framework for regulation defined in the Nuclear Waste Policy Act (NWPA) remains unchanged. Specifically, it is assumed that the Environmental Protection Agency will be charged with promulgating environmental standards for disposal and that the Nuclear Regulatory Commission will be charged with reviewing applications for disposal facilities using licensing requirements and criteria consistent with the EPA standards. Second, that existing generic disposal standards will be updated or replaced.
