With increasing demand for clean, reliable, and safe sources of energy, the conversation around nuclear energy is changing. And so too is the conversation around nuclear waste, even as the country struggles to find a path for the disposal of its spent nuclear fuel and high-level radioactive waste. From community engagement, to recycling, to existing success around other forms of nuclear waste management, the conversation around nuclear waste has many different angles, and an executive session of the American Nuclear Society’s 2024 Annual Conference in Las Vegas aimed to delve into some of those discussions.

A collaboration between the DOE and Bechtel National set a foundation for requirements engineers will follow in continuing the design of the facility. (Photo: DOE)
The Department of Energy’s Office of Environmental Management announced that its Office of River Protection (ORP) recently created a plan with contractor Bechtel National for completing the High-Level Waste Facility at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany have investigated a microorganism capable of transforming water-soluble hexavalent uranium [U(VI)] to the less-mobile tetravalent uranium [U(IV)]. The researchers found that the sulfate-reducing bacterium Desulfosporosinus hippei, a relative of naturally occurring microorganisms present in clay rock and bentonite, showed a relatively fast removal of uranium from clay pore water.

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.

Nukem Technologies, a German-based radioactive waste management company, announced last week that it has successfully completed a mock-up for a state-of-the-art waste solidification plant. The plant will use the in-drum cementation process for encapsulating various types of radioactive waste into a solid, secure form suitable for long-term storage.
