Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Oklo completes end-to-end demonstration of advanced fuel recycling
Oklo Inc. has announced that it has completed the first end-to-end demonstration of its advanced fuel recycling process as part of an ongoing $5 million project in collaboration with Argonne and Idaho National Laboratories. Oklo’s goal: scaling up its fuel recycling capabilities to deploy a commercial-scale recycling facility that would increase advanced reactor fuel supplies and enhance fuel cost effectiveness for its planned sodium fast reactors.

The evolution and formation of a redox front in the near field of a repository for high-level nuclear waste is modeled, considering the effect of a time-dependent source term of the oxidizing species produced by radiolysis of the water entering the canister. The transport of oxidants in the clay surrounding the canister occurs by diffusion. In the rock, the transport of oxidants is modeled as occurring through fractures, with diffusion into the rock matrix. The results show that it is not probable that the redox front will ever move past the bentonite. If it does, the tips of the redox front may move <100 m over a million year period in a channel with a high flow rate.
