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.

Tritium processing operations have been performed at the Savannah River Site (SRS) since 1955. During this time, tritium handling and processing operations have been continually improving. In 1987 construction began on a new tritium handling facility, the Replacement Tritium Facility. This new facility, which is scheduled for startup in 1992, makes use of the latest technology to enhance operational safety, ensure material safeguards and security, and avoid tritium losses to the environment. One of the new technologies incorporated into the Replacement Tritium Facility is the application of metal hydrides to store, separate, purify, pump, and compress hydrogen isotopes. This paper will provide an overview of the new Replacement Tritium Facility, and in addition will review the role and impact of metal hydride technology in present and future tritium processing operations at SRS .
