The Department of Energy’s National Nuclear Security Administration hopes to dispose of up to 34 metric tons of surplus defense-related plutonium at the Waste Isolation Pilot Plant in New Mexico using a “dilute-and-dispose” strategy.
The Canadian Nuclear Safety Commission has decided to amend Canadian Nuclear Laboratories’ operating license for the Chalk River Laboratories, allowing the construction of a near surface disposal facility (NSDF) for low-level radioactive waste on the nuclear research site in Deep River, Ontario.
The Department of Energy, in conjunction with Massachusetts Institute of Technology and Texas A&M University, will conduct a biweekly webinar series aimed at providing a broad overview of nuclear waste management and disposal in the United States as well as the latest research activities. The target audience is undergraduate and graduate students in science, engineering, policy, sociotechnical, and social science programs.
The Department of Energy’s Office of Environmental Management said Idaho’s Integrated Waste Treatment Unit (IWTU) is set to resume radioactive liquid waste treatment operations early next year after crews replaced carbon material from two plant vessels. The IWTU was shut down for an unplanned outage on September 6 to address elevated mercury concentrations in the plant’s granulated activated carbon (GAC) beds, according to Defense Nuclear Facilities Safety Board (DNFSB) reports.
Department of Energy contractor Savannah River Nuclear Solutions (SRNS) said its Savannah River Site employees recently used an innovative method to ensure the integrity of radioactive material storage containers currently in long-term dry storage at the South Carolina site.
The “How do we talk about the Back End?” session at the ANS Winter Conference & Expo on Wednesday, November 15, focused on recent experiences in communicating about used nuclear fuel to a skeptical public.
Bechtel and the Department of Energy’s Office of Environmental Management announced on December 4 that the first set of test glass was successfully poured into a stainless-steel storage container designed to hold vitrified waste at Hanford’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.
Commissioning has begun on a new large-scale ventilation system at the Waste Isolation Pilot Plant in New Mexico.
The Safety Significant Confinement Ventilation System (SSCVS) is expected to increase underground airflow from 170,000 cubic feet per minute up to 540,000 cfm. The increased airflow will allow for simultaneous underground waste emplacement, mining, and ground control work. Ground control, including bolting, controls the movement of salt rock—known as salt creep—in the WIPP underground.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.
The Department of Energy’s Office of Environmental Management said crews at its Hanford Site in Washington state have started pouring the first molten glass from a waste vitrification melter into a stainless steel container at the site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.
The American Nuclear Society coordinated an effort with eight nongovernmental organizations in asking Congress to update the Environmental Protection Agency’s generic standards for the safe, permanent disposal of spent nuclear fuel (SNF) and high-level radioactive waste.
The Nuclear Energy Agency has announced a new collaboration with the Electric Power Research Institute on an upcoming project that will focus on waste management strategies for small modular reactors and advanced nuclear energy systems.
The Nuclear Regulatory Commission and the U.S. Department of Justice are asking the 5th U.S. Circuit Court of Appeals to review its decision to vacate Interim Storage Partners’ license to build and operate a consolidated interim storage facility (CISF) for commercial spent nuclear fuel in Andrews County, Texas.
Ontario Power Generation (OPG) subsidiary Laurentis Energy Partners has opened, in partnership with EnergySolutions Canada, a new 42,000-square-foot facility in Kincardine, Ontario, that will minimize waste associated with nuclear energy generation in the Canadian province, the company announced this week.
The Department of Energy is seeking the public’s input on the Hanford Site’s 5-year plan, which outlines planned cleanup work either to be completed or initiated at the former plutonium production site near Richland, Wash. The DOE updates Hanford’s 5-year plan annually to reflect current progress and ongoing integrated planning for future work at the site.
The Nuclear Waste Management Organization, the not-for-profit organization responsible for managing Canada’s spent nuclear fuel, said it will begin developing a plan for a consent-based siting process for a deep geologic repository for intermediate-level and nonfuel high-level radioactive waste.
More than 3,000 employees with Department of Energy contractor Savannah River Mission Completion (SRMC) participated in a vision casting initiative, learning more about the past, present, and future of the Savannah River Site’s liquid waste mission.
The Department of Energy’s National Nuclear Security Administration recently marked the completion of a new long-term radioactive waste storage facility in Kazakhstan.
The facility, at Kazakhstan’s Institute of Nuclear Physics (INP), has been operational since 2022 and has an expected lifespan of 50 years. According to the NNSA, the facility conforms with all Kazakhstan and International Atomic Energy Agency guidelines and replaces a much older facility located at an INP property in Turaz.
The Advanced Research Projects Agency–Energy (ARPA-E), a branch of the Department of Energy, is tasked with driving the research and development of cutting-edge energy technologies. The agency’s core emphasis is on mitigating emissions, increasing energy efficiency, reducing imports, ensuring energy systems resiliency, and offering transformative solutions for the management of radioactive waste and spent nuclear fuel (SNF). Its mission is instrumental in ensuring the United States retains its technological superiority in the design and implementation of new energy technologies. Efforts in SNF research also benefit prior investments in ARPA-E’s MEITNER (Modeling-Enhanced Innovations Trailblazing Nuclear Energy Reinvigoration) and GEMINA (Generating Electricity Managed by Intelligent Nuclear Assets) programs, which seek to substantially decrease the capital and operational expenditures associated with advanced reactors (ARs).
Workers at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, have begun removing the first three of 18 temporary startup heaters, the Department of Energy announced on September 12. The startup heaters were used to raise the first of two 300-ton glass melters in the plant’s Low-Activity Waste Facility to its operating temperature of 2,100°F.
