Hi Mike, section 5 our submission to a current Senate inquiry has details on costs and cost escalations for planned overseas waste dumps, and info on the 2014 explosion in the US intermediate-level dump, etc. The submission is online at the Senate inquiry site.
Also a mountain of info on failed plans for a national dump in Australia at https://nuclear.foe.org.au/waste/
Some of the highlights / lowlights (as discussed):
– plans for a dump on defence department land in the NT were abandoned — putting it on defence department land doesn’t automatically solve community opposition, Traditional Owner opposition, opposition along transport corridors, etc
– under the Howard government, Defence Department publicly opposed plans for a dump near Woomera because of the risk of a missile strike (see articles below)
– appalling mismanagement of waste secretly trucked to Woomera Prohibited Area many years ago: https://nuclear.foe.org.au/woomera/
– no current efforts to find a disposal site for Australia’s long-lived intermediate-level waste (also destined for deep underground disposal), last half-hearted effort was the National Store project from 2001-2004, abandoned at the same time as Howard govt abandoned efforts to impose a dump for lower-level wastes near Woomera
Let me know if you want any more info
cheers, Jim
