A silver chloride–based cleanup technology is expected to reduce radioactive iodine-129 contamination found in soil and groundwater near the center of the Department of Energy’s Savannah River Site in South Carolina to levels well below regulatory limits. The I-129 was created during the production of plutonium and tritium at the site throughout the Cold War era.

Ukraine’s State Nuclear Regulatory Inspectorate (SNRIU) has authorized the operation of Chernobyl’s Interim Storage Facility (ISF-2), allowing spent nuclear fuel from the plant’s three undamaged reactors to be loaded into the dry storage facility. The handover of the ISF-2 operating license was carried out during a ceremony held on April 26, the 35th anniversary of the Chernobyl accident, and was attended by Ukraine’s president, Volodymyr Zelensky.

On April 26, 1986, reactor No. 4 of the Chernobyl nuclear power plant in Ukraine exploded, sending radioactive material into the environment and across Europe. After 35 years, Ukrainians are looking to the site of the world’s worst nuclear disaster “for inspiration, solace, and income,” according to an ABC News report.

The Waste Isolation Pilot Plant in southeastern New Mexico is once again accepting shipments and processing transuranic waste following a two-month annual maintenance outage. According to the Department of Energy, WIPP is back to accepting five waste shipments per week, with post-pandemic plans to increase shipments to 10 per week.

How the Nuclear Regulatory Commission collects information in the licensing of spent nuclear fuel can be improved by a better understanding of the concept of risk-informed decision making, according to a report, Audit of the NRC’s Use of Requests for Additional Information in Licensing Processes for Spent Nuclear Fuel (OIG-21-A-08), by the agency’s Office of Inspector General (OIG).

The Department of Energy’s Office of Environmental Management (EM) has released its Strategic Vision 2021-2031 (hereinafter referred to as the 2021 Strategic Vision), a blueprint to the cleanup program’s anticipated accomplishments over the next decade. The new strategic vision updates EM’s previous report, A Time of Transition and Transformation: EM Vision 2020-2030, released in March of last year.

Workers at the Department of Energy’s Savannah River Site in South Carolina recently finished transferring equipment to the site’s K Area in preparation of shipping downblended plutonium to the Waste Isolation Pilot Plant in New Mexico for disposal. The plutonium is part of the 34 metric tons of surplus plutonium the National Nuclear Security Administration plans to ship to WIPP under the “dilute and dispose” option the department adopted following the cancellation of the MOX Fuel Fabrication Facility project.

Saying they are cautiously optimistic that the Biden administration can change the U.S. trajectory on nuclear waste, some Stanford University experts have offered their recommendations on how it can be done in a recent Stanford news posting.

Rep. Newhouse urges DOE to uphold HLW interpretation

Newhouse

In a letter written to Energy Secretary Jennifer Granholm, Rep. Dan Newhouse (R., Wash.) has urged the Department of Energy to maintain its 2019 interpretation of high-level radioactive waste. Newhouse was responding to a letter sent to Granholm by several special interest groups and state leaders asking that the DOE immediately rescind the HLW interpretation.

That special interests/state leaders letter, sent on February 26—one day after Granholm was confirmed as energy secretary—was signed by Washington attorney general Bob Ferguson, Washington State director of ecology Laura Watson, and Phil Rigdon of the Yakama Nation, along with representatives from Natural Resources Defense Council, Hanford Challenge, and Columbia Riverkeeper. The letter said, in part, “We look forward to working with you on the Department’s cleanup of legacy nuclear waste at sites such as the Hanford Nuclear Reservation located near Tri-Cities, Washington. Washington houses 60 percent of the nation’s High-Level Radioactive Waste with 56 million gallons stored in 177 underground storage tanks at Hanford."

A new wastewater filter system being installed at Hanford’s Effluent Treatment Facility (ETF) is expected to increase waste processing throughput, improve efficiency, and save money as the site in southeastern Washington gears up to treat tank waste, the Department of Energy announced.

Sparks from Los Alamos waste drum prompt WIPP evacuation

April 2, 2021, 6:56AMRadwaste Solutions

The Waste Isolation Pilot Plant's underground repository in New Mexico was evacuated for 13 days in March following an incident at Los Alamos National Laboratory, where a drum being packed with transuranic waste began emitting sparks.

As reported on March 31 by the Carlsbad Current Argus, an evacuation order was given on March 5 after WIPP was informed by the National Nuclear Security Administration that similar at-risk drums from LANL were emplaced for disposal in the repository. The order was lifted on March 18 after it was determined that the drums were compliant with WIPP’s waste acceptance criteria and did not pose a risk.

To protect a treasured ecological species of northern New Mexico, the Los Alamos Field Office (EM-LA) of the Department of Energy’s Office of Environmental Management and its contractor N3B this month began their annual task of modifying legacy waste cleanup activities at Los Alamos National Laboratory ahead of the Mexican spotted owl breeding season.

The U.S. Fish and Wildlife Service (USFWS) listed the owl as a threatened species in 1993, when population numbers were decreasing drastically due to the loss, degradation, and fragmentation of their habitat.

New Mexico attorney general Hector Balderas has filed suit against the Nuclear Regulatory Commission and the United States, seeking to stop Holtec International’s application to build and operate its HI-STORE consolidated interim storage facility for used nuclear fuel in the state. The complaint, filed in the U.S. District Court of New Mexico on March 29, seeks a declaratory judgment that the NRC is acting beyond the scope of its authority and an injunction preventing the licensing from moving forward.

NRC pushes back safety review of Holtec’s interim storage site

March 30, 2021, 12:00PMRadwaste Solutions

The Nuclear Regulatory Commission has delayed the release of a safety report for Holtec International’s HI-STORE consolidated interim storage facility proposed for New Mexico, claiming it needs additional information to complete its review of the license application. The NRC previously said it would complete its safety review and publish a safety evaluation report for the spent fuel storage facility by May.
