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?
Since the Yucca Mountain nuclear waste repository has gotten the axe from President Obama, nuclear power plants around the country are faced with the prospect of virtually indefinite "temporary" storage of their nuclear waste in the form of spent fuel rods. The US Department of Energy has a legal obligation to find a permanent disposal facility for the spent fuel, and the agreements currently in place presumed that Yucca Mountain would be accepting nuclear waste by 2025 which clearly won’t happen. (Photo of dry cask temporary storage method for spent nuclear fuel from Connecticut Yankee). More after the break. […]
Although they are nearly at the final depth, the work thus far has been primarily to construct the 4-km long access tunnel. The facility is not scheduled to accept the nuclear waste until 2020 but […]

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]
