Dismantling the Cold War Stockpile

3

• NNSA has dismantled thousands of weapons and is ahead of schedule to meet Administration commitments

• Already dismantled:– FY 1994 thru FY 2014: 10,251– FY 2010: 352– FY 2011: 305– FY 2012: 308– FY 2013: 239– FY 2014: 299

• Commitment to seek funds in FY17 to accelerate the rate of dismantlement by 20 percent

The President has committed to the dismantlement of all weapons systems retired prior to 2009, by the end of 2022. DOE is ahead of schedule in meeting that goal, with

42% of those weapons already dismantled over a period comprising 38% of the time allotted.- DOE Strategic Plan, May 2011

Sandia National Lab

Diplomatic representatives from 11non-nuclear weapons states + UN Office of DisarmamentAffairs spent two days at U.S. national laboratories exploring technologies behind stockpile stewardship, nonproliferation, armscontrol, and peaceful uses

Results: increased understanding that – – underground testing can be replaced

by science– warhead life extensions provide

foundation for future arms reductions

– human & physical resources from U.S. nuclear enterprise can be applied to global challenges
