DOE isn’t systematically using foreign nuclear-cleanup lessons

Britain says it saved at least £2 billion ($2.6 billion) by using risk to decide which low-radioactivity waste actually required repository disposal; Canada expects to finish one priority site nearly 30 years early; and Britain and France use replica test facilities to troubleshoot and train before touching live sites. GAO says DOE shares too few such lessons across its 15 U.S. cleanup sites—even though DOE estimates the remaining mission could cost $641 billion to $840 billion and last until 2100.
