Sustaining the Nuclear Enterprise - A New Approach [1]: "Two weeks ago, John Fleck at the Albuquerque Journal reported (subscription only) that the nuclear weapons labs are lining up behind a plan to scrap the curent ‘Stockpile Stewardship Program’ developed to maintain US nuclear weapons without testing:

The United States’ current approach to maintaining its nuclear arsenal ‘looks increasingly unsustainable,’ according to an internal report by senior officials at the nation’s three nuclear weapons labs.

The nuclear weapons program’s future costs exceed the available budget, and the effort to maintain aging warheads is forcing the nation to retain a larger nuclear arsenal than would otherwise be needed, the report concludes."
