The rapid changes in the nuclear energy industry over the last decade, driven in part by fluctuating energy market prices and an aging fleet of reactors, have led to the closure of multiple reactors in the United States and other countries. These closures have increased the need for larger and more efficient ways to manage low-level radioactive waste processing and transport capacities. The safe transport of radioactive material is a key component of the overall nuclear industry reliability. Though sometimes perceived as a bottleneck and costly, it is necessary to send waste material to disposal.

The Nuclear Regulatory Commission has delayed issuing a decision on the licensing of Holtec International’s proposed consolidated interim storage facility (CISF) in New Mexico for at least two more months. In a letter sent to Holtec on March 20, the NRC said the delay was “due to unforeseen resource constraints.”

Progress continues on a new utility shaft at the Department of Energy’s Waste Isolation Pilot Plant in New Mexico as shaft-sinking crews recently surpassed the midway point at a depth of 1,076 feet. When complete, the full shaft depth will be 2,275 feet, with the team now halfway to the WIPP repository depth of 2,150 feet.

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.

Waste Management 2023: Innovation, transformation, and sustainability

March 20, 2023, 3:01PMRadwaste Solutions

Attracting more than 2,000 attendees, the 2023 Waste Management Symposia was held February 26–March 2 in Phoenix, Ariz. For many, this year’s conference was a return to business as usual, with a packed exhibit hall and well-attended technical session, as the upheaval brought about by the pandemic that began three years earlier seemed a thing of the pasts. Not that those who gathered in Phoenix threw any caution to the unseasonably cold and rainy winds that descended across Arizona this year.

Following a second planned maintenance outage, the Tank-Side Cesium Removal (TSCR) system at the Hanford Site in Washington state has resumed processing liquid tank waste, the Department of Energy’s Office of Environmental Management (EM) announced on March 14.

According to EM, its Office of River Protection (ORP) and contractor Washington River Protection Solutions processed more than 25,000 gallons of waste during the previous week and has treated a total of 406,000 gallons of radioactive liquid waste since TSCR began operations early last year.

A key component in Hanford’s Direct-Feed Low-Activity Waste program for treating tank waste, TSCR removes radioactive cesium and solids from tank waste and delivers low-activity waste to a nearby million-gallon tank, where it is staged until it can be fed to the Waste Treatment and Immobilization Plant for vitrification.

Outage improvements: During outages, workers change out filter columns that remove radioactive solids during waste processing, perform maintenance, and apply lessons learned from operations. According to EM, many improvements to the treatment system during outages over the past year came from recommendations made by workers and contractor and federal staff on the project team.

WM Symposia: The best presentations/papers of 2022

March 16, 2023, 12:00PMRadwaste Solutions

Hosted by Waste Management Symposia, the annual Waste Management Conference is widely regarded as the premier international conference on the management of radioactive material and related topics. The theme of this year’s conference, being held February 26-March 3 at the Phoenix Convention Center in Arizona, is “Planning for the Future: Innovation, Transformation, Sustainability.” The featured country for 2023 is France, which will be represented by numerous panels, papers, posters, and exhibits demonstrating the country’s continuous innovation and pragmatism in the management of the nuclear fuel cycle. The featured Department of Energy Office of Environmental Management topic is “EM’s Transformation in Radioactive Liquid Tank Waste Management.”

Each year, the two best oral presentations/papers from the previous year’s conference are recognized. Honoring the highest-quality presentations, the American Nuclear Society and the American Society of Mechanical Engineers each present an award for best presentation/paper. The following are the abstracts for the best ANS and ASME papers of 2022. The full papers are available to 2023 WM Conference participants through the WM Symposia website, at wmsym.org.

Locked in glass: The vitrification of LLW streams

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.

Hanford’s DFLAW operations unlikely to begin in 2023

Hanford’s waste vitrification operations are unlikely to start by the Department of Energy’s year-end goal, said Brian Vance, manager of the DOE’s Office of River Protection and Richland Operations Office for the Hanford Site in Washington state. The DOE is working to meet its obligations to begin processing Hanford’s low-level radioactive tank waste as part of its Direct-Feed Low-Activity Waste (DFLAW) program.

“The probability for 2023 is very low,” Vance said, regarding the department’s plan to begin vitrifying the tank waste. Vance made his remarks during a panel session of the 2023 Waste Management Symposia in Phoenix, Ariz., on February 28.

The Energy Communities Alliance (ECA), an organization of local communities near Department of Energy national defense sites, has released a new report urging the DOE to prioritize finding disposal pathways for the radioactive waste it is obligated to clean up.

According to the ECA, the DOE could potentially save hundreds of billions of dollars in cleanup costs by using its available tools and implementing the recommendations contained in the report, Disposal Drives Cleanup: Re-Energizing Momentum for Disposal Solutions for Radioactive Waste.

New Generic Repository Environmental Standards: Draft Recommendations from ANS

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.
