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?
More problems for the US Department of Energy related to the Yucca Mountain Nuclear Waste Repository. The New York Times is reporting that the DOE is already 10 years behind in a commitment made to Power Companies to store their nuclear waste, and according to the DOE, it will likely be at least another 10 years before they are able to begin accepting waste for permanent storage. Who cares you ask? Well, the US has already payed out $342 million in 60 lawsuits filed by utility companies, and that total could reach $11 billion according to government estimates or $35 billion according to industry estimates before Yucca Mountain finaly opens and begins accepting waste.
