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.

The JAERI (Japan Atomic Energy Research Institute) Fuel Cleanup system (JFCU), which accepts simulated fusion reactor exhausts and produces pure hydrogen isotopes and tritium-free waste, was tested at the Tritium Systems Test Assembly (TSTA) with gram levels of tritium in 1991 under the US/Japan collaboration program on Fusion Technology. In 1991, the JFCU system integrity and safe operation with gram level tritium were demonstrated. Component performances with tritium were also measured and further subjects for R&D were uncovered. The resident tritium inventory of the JFCU was evaluated at about six grams during TSTA loop operation with a DT (1:1) mixture. After these tests, all tritium used in the experiments was recovered as hydrogen isotopes gases.
