The Idaho National Laboratory is moving closer toward closing its largest building—which, at more than 316,000 square feet, could comfortably house a modern U.S. aircraft carrier, according to the Department of Energy.

The Department of Energy’s Carlsbad Field Office announced that it has made a significant step toward increasing airflow to the Waste Isolation Pilot Plant (WIPP) underground with the excavation of a new utility shaft. According to the office, crews working on the shaft recently reached an underground depth, known as station depth, that will allow horizontal tunneling work to begin on connecting the shaft to the WIPP repository complex.

Located in southeastern New Mexico, the repository for defense-related transuranic waste sits 2,150 feet below ground level. Airflow to the underground has been restricted following a radiological release in 2014.

When completed, the 26-foot-diameter utility shaft will provide air to WIPP’s new ventilation system, called the Safety Significant Confinement Ventilation System (SSCVS). The increased airflow provided by the system will allow for simultaneous mining, rock bolting, waste emplacement, and maintenance operations.

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.

The Department of Energy’s Waste Isolation Pilot Plant (WIPP) recently marked a milestone after its drivers exceeded 16 million safe miles without a serious accident or injury—equivalent to 33 round trips to the moon or more than 642 trips around the world, the DOE’s Office of Environmental Management announced.

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.

Two Department of Energy sites recently announced training partnerships with local technical and community colleges designed to offer students hands-on work experience while building a workforce pipeline to waste management jobs.

On December 1, 2021, the Department of Energy issued a request for information (RFI) asking for public feedback on using consent-based siting to identify sites for the interim storage of spent nuclear fuel. The department received more than 220 comments in response, and on September 15, 2022, the DOE released a report summarizing and analyzing those responses. That 57-page report, Consent-Based Siting: Request for Information Comment Summary and Analysis, will be followed by an updated consent-based siting process document.

The DOE’s consent-based siting initiative is being led through the DOE’s Office of Nuclear Energy. To learn more about that initiative and the consent-based siting process, Radwaste Solutions spoke with the DOE’s Kim Petry, acting associate deputy assistant secretary, Spent Fuel and Waste Disposition; Erica Bickford, acting office director, Integrated Waste Management; and Natalia Saraeva, team lead, Consent-Based Siting.

Waste management startup Deep Isolation announced that it has entered into a mentor-protégé agreement with Salado Isolation Mining Contractors (SIMCO), the new Bechtel National–led management and operations contractor for the Department of Energy’s Waste Isolation Pilot Plant in New Mexico.

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.

While still lacking a deep geological repository for the permanent disposal of its commercial used nuclear fuel and high-level radioactive waste, the United States does have regulatory standards for geological nuclear waste disposal.

Having been written nearly 40 years ago, however, those standards are outmoded and lack transparency, according to a special committee of the American Nuclear Society, which has released draft recommendations on revising public health and safety standards for future geological repository projects in the United States.

Salado Isolation Mining Contractors (SIMCO), a single-purpose entity comprised of Bechtel National and Los Alamos Technical Associates as a teaming contractor, has assumed responsibility for managing and operating the Waste Isolation Pilot Plant in New Mexico.

The Department of Energy’s National Nuclear Security Administration and Office of Environmental Management have completed the first shipment of downblended surplus plutonium transuranic (TRU) material from the K Area at the Savannah River Site in South Carolina to the Waste Isolation Pilot Plant in New Mexico.

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.

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.

Taking waste into outer space would require quite large vehicles, like the Saturn 5 rocket shown here carrying the Apollo 14 crew to the moon. A huge fireball forms underneath the rocket . . . hmm, would that be wise? (Source: NASA)

Nuclear waste disposal presents a frustrating problem far beyond its actual danger. No one has ever been harmed by commercial nuclear waste, and no one is likely to ever be harmed.

But we do have to find a final resting place for nuclear waste as it decays away back to the levels of the ore from which it came.

There are several types of nuclear waste: low-­level waste (LLW), intermediate-­level waste (ILW), transuranic waste (TRU; referring only to bomb waste without a lot of ­cesium-­137 or strontium-­90), high-­level waste (HLW; also only bomb waste), and spent nuclear fuel (SNF; from commercial power plants only). In the United States, TRU waste, HLW, and SNF require deep geologic disposal by law.

Mine rescue teams from the Department of Energy’s Waste Isolation Pilot Plant (WIPP) finished in the top 15 in competitions at the first-ever joint Coal, Metal, and Nonmetal National Mine Rescue Contest in Lexington, Ky., held on August 7–12.

Reston, Va.-based Tularosa Basin Range Services (TBRS), a single-purpose entity under the umbrella of Bechtel National, has been awarded the 10-year, $3 billion management and operating contract for the Waste Isolation Pilot Plant (WIPP) by the Department of Energy’s Office of Environmental Management (EM). Located near Carlsbad, N.M., WIPP is the DOE’s geologic repository for defense-generated transuranic waste.

The new contract replaces the current WIPP M&O contract held by Nuclear Waste Partnership, which expires on September 30. The contract with TBRS was announced on July 11.

The Department of Energy’s Office of Environmental Management (EM) has awarded CAST Specialty Transportation a contract to provide transportation services for the Waste Isolation Pilot Plant, the DOE’s repository for defense-generated transuranic (TRU) waste near Carlsbad, N.M.
