More nuclear waste is being sent from a federal national lab in the state of Washington to the underground repository near Carlsbad.
The U.S. Department of Energy said 130 large waste containers were recently exhumed from two underground storage sites at the federal Hanford Site in the southern region of Washington.
The containers, containing transuranic (TRU) nuclear waste, stand about 19 feet tall and weigh about 50 tons, according to a report from the energy department’s Office of Environmental Management.
They were sent to an offsite location, read the report, to be repackaged into smaller containers and shipped to southeast New Mexico for burial at WIPP.
At WIPP, the energy department disposes of the TRU waste, which is clothing materials, equipment and other debris irradiated during nuclear activities.
The waste is buried at WIPP in a salt deposit about 2,000 feet underground. The salt gradually collapses on the waste, burying the refuse and blocking radiation from escaping.
Scott Green, manager of the department’s Hanford Field Office, said the removal and packaging of the waste was completed “with no incidents.”
“This project not only reduces risk but meets a significant regulatory milestone,” Green said.
The tank removal was required by the U.S. Environmental Protection Agency and the state of Washington’s Department of Ecology through a 2018 agreement with the Department of Energy.
Known as the “Tri-Party Agreement” the deal required removal of all containers from outside storage areas at Hanford by Sept. 30, 2026.
The Tri-Party Agreement, officially called the Hanford Federal Facility Agreement and Consent Order, was signed by the three entities in 1989. It required all tank waste at Hanford be disposed of within 40 years – 2029.
“These milestones represent the actions necessary to ensure acceptable progress toward Hanford Site compliance,” read the agreement. “The goal of these milestones is to achieve timely and appropriate cleanup of the Hanford Site.”
Most of the exhumed containers include material such as metal, glass, and fiberglass-reinforced plywood irradiated during Hanford’s nuclear weapons production activities, read the report.
Removing the 130 containers and preparing them for disposal took about six years, according to Andy Drom, project director at Central Plateau Cleanup Company, the contractor hired by the federal government to oversee the Hanford Site.
“The success of this work is testimony to what can be achieved by working together to meet the challenges of our critical cleanup mission head-on,” Drom said.
Idaho also has waste removal agreement
WIPP took in about 572 shipments from Hanford since the repository opened in 1999, representing about 4% of the 14,687 shipments the facility has received as of Dec. 13, according to Department of Energy records.
The majority of WIPP’s waste – 7,767 shipments or 53% of the total – was sent from Idaho National Laboratory.
That facility was prioritized for WIPP under a 1995 settlement agreement between the federal government and the state of Idaho.
The agreement allowed the federal government to store some spent nuclear fuel in Idaho, and in exchange “expedite the treatment and permanent removal of waste” from the state.
All TRU waste was required to be removed by 2018, a deadline not met due to a three-year (2014-2017) shutdown of WIPP’s primary operations after a disposal drum ruptured and contaminated parts of the underground, according to a 2019 report from the Leadership in Nuclear Energy Commission.
Both agreements were criticized by New Mexico Environment Department Cabinet Secretary James Kenney, who said the deals were signed without input from WIPP’s host state.
He said this had the effect of “deprioritizing” New Mexico for nuclear waste cleanup, despite its acceptance of the risk associated with such work.
In 2023, the energy department signed a 10-year renewal of its operating permit with the state of New Mexico. The permit, overseen by Kenney’s environment department, included a clause requiring waste from Los Alamos National Laboratory to be prioritized.
