With an ID of around 10-in (260-mm), I get the sense they would need multiple boreholes to dispose of any significant quantity of waste.The waste would be sealed within two stainless steel canisters, and placed within a permanent steel casing that is grouted into place. The bottom of the hole would be plugged first, and the top would have some kind of backfill. I imagine the key to this technology is the geologic media the waste is being stored in. Obviously a site with a deep groundwater table would be significant. Any thoughts on what else one would be looking for in terms of the site and specifically the geology? Do you think the U.S. would ever implement such a system?

NRC RECEIVES DOEâ€™S LICENSE APPLICATION TO CONSTRUCT HIGH-LEVEL NUCLEAR WASTE REPOSITORY AT YUCCA MOUNTAIN
The Nuclear Regulatory Commission received an application today from the U.S. Department of Energy for a license to construct the nationâ€™s first geologic repository for high-level nuclear waste at Yucca Mountain, Nev.
â€œWe are ready to get to work on this challenging review,â€ said NRC Chairman Dale E. Klein. â€œCongress has given the NRC a strict timetable for reviewing this application, and I want to assure the American people that we will perform an independent, rigorous and thorough examination to determine whether the repository can safely house the nationâ€™s high-level waste. The NRCâ€™s licensing decision will be based entirely on the technical merits.â€ [Editor] Read on for the rest of the press release [/Editor]
