Retrieval of nuclear waste canisters from a borehole
Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.

A system has been developed for the production of 99mTc based on distributed electron accelerators and thermal separation. The radioactive decay parent of 99mTc, 99Mo, is produced from 100Mo by a photoneutron reaction. Two alternative thermal separation processes have been developed to extract 99mTc. Experiments have been performed to verify the technical feasibility of the production and assess the efficiency of the extraction processes. A system based on this technology enables the economical supply of 99mTc for a large nuclear pharmacy. Twenty such production centers distributed near major metropolitan areas could produce the entire U.S. supply of 99mTc at a cost less than the current subsidized price.
