The Department of Energy’s Office of Environmental Management announced last week that, for calendar year 2023, the department’s Waste Isolation Pilot Plant (WIPP) had its best shipment performance in 10 years, having received 489 transuranic (TRU) waste shipments from generator sites throughout the country. For comparison, WIPP received only 272 shipments in 2022.

For the first time in a decade, crews have started mining a new disposal panel at the Department of Energy’s Waste Isolation Pilot Plant (WIPP) in New Mexico, the nation’s deep geologic waste repository for defense-related transuranic waste.

2023 in Review: October–December

January 16, 2024, 3:01PMNuclear News

Another calendar year has passed. Before heading too far into 2024, let’s look back at what happened in 2023 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from October through December 2023.

Stay tuned for the top stories from the rest of the past year.

The Department of Energy’s Office of Environmental Management and the New Mexico Environment Department (NMED) have negotiated a settlement on terms to renew the 10-year operating permit for the Waste Isolation Pilot Plant near Carlsbad, N.M. The DOE, along with WIPP’s operating contractor, Salado Isolation Mining Contractors, and the NMED negotiated the settlement with New Mexico stakeholders.

New Mexico tightens restrictions on WIPP permit renewal

The New Mexico Environment Department (NMED) is adding several conditions to the operating permit for the Department of Energy’s Waste Isolation Pilot Plant (WIPP) near Carlsbad, N.M. The permit changes, which would prioritize the disposal of transuranic (TRU) waste generated in the state and limit the repository’s capacity, are contained in a fact sheet the NMED.

WIPP begins placing TRU waste in Panel 8

Employees have begun emplacing defense-related transuranic (TRU) waste in Panel 8 of the Waste Isolation Pilot Plant (WIPP) in New Mexico, the Department of Energy’s Office of Environmental Management (EM) announced in November. TRU waste is permanently disposed of at WIPP in rooms mined in a Permian salt bed 2,150 feet below the surface.

DOE late in removing Los Alamos TRU waste, Texas says

The Texas Commission on Environmental Quality is threatening enforcement action against the Department of Energy for failing to meet its obligations in removing containers of transuranic waste currently in temporary storage at Waste Control Specialists’ Federal Waste Facility in West Texas.

The Department of Energy reported this month that the final container of legacy transuranic waste from the Savannah River Site arrived at the Waste Isolation Pilot Plant for permanent disposal on the afternoon of April 14. The shipment capped the end of a journey for 239 shipments that began in 2011.

In all, trucks that carried the shipments weighed a combined 11,402,000 pounds and travelled more than 347,000 miles to the WIPP site.

Radiography unit at SRS verifies contents of TRU shipments to WIPP

Operators at the Savannah River Site’s Solid Waste Management Facility can now characterize and certify newly generated TRU waste through the use of a real-time radiography unit that uses an X-ray system to examine the contents of waste containers. The equipment was recently installed to meet updated requirements set by the Department of Energy’s National TRU Program that involve evaluating the containers for chemical compatibility and oxidizing chemicals.

The shipments of TRU waste from SRS, in South Carolina, are sent to the Waste Isolation Pilot Plant (WIPP), in New Mexico, for disposal.

N.M. court upholds WIPP’s waste volume permit modification

November 19, 2021, 12:30PMRadwaste Solutions

The New Mexico Court of Appeals upheld a permit modification allowing the Department of Energy and its contractor Nuclear Waste Partnership (NWP) to change how the volume of transuranic (TRU) waste emplaced at the Waste Isolation Pilot Plant near Carlsbad is calculated.

DOE completes mining of WIPP’s Panel 8

The Department of Energy’s Office of Environmental Management this week announced that after seven years, mining of the Waste Isolation Pilot Plant’s Panel 8 is finished. Created from an ancient salt formation 2,150 feet below the surface, Panel 8’s seven emplacement rooms are the next destination for transuranic waste brought to WIPP from DOE sites throughout the country.

New area for TRU waste emplacement takes shape at WIPP

The amount of salt mined so far from Panel 8 at the Department of Energy’s Waste Isolation Pilot Plant (WIPP) is a lot. The DOE’s Office of Environmental Management (EM) compared the amount to the weight of more than 46,000 Ford F-150s, about 16,000 African bush elephants, nearly 510 Boeing 747s, two Titanics, or enough to coat the rims of 3.6 million margarita glasses.

Miners working 2,150 feet underground extract the salt using grinders called continuous miner machines to create space to place defense-related transuranic (TRU) waste.

With WIPP’s Panel 8 scheduled for completion in a little more than half a year, crews recently crossed the 100,000-tons-mined threshold and, as of mid-June, are at 105,000 tons removed from the panel.

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.

WIPP could run out of disposal space, GAO says

A study of the Department of Energy’s Waste Isolation Pilot Plant in New Mexico has found that the repository faces long-term issues with ensuring sufficient physical space and statutory capacity to dispose of the federal government’s inventory of transuranic (TRU) waste. WIPP is the United States’ only repository for the disposal of TRU waste generated by the DOE’s nuclear weapons research and production.

The Government Accountability Office study, Better Planning Needed to Avoid Potential Disruptions at Waste Isolation Pilot Plant (CAO-21-48), was published on November 19.
