Office of Classification
Department of Energy

Dear Dr. Weston-Dawkes:

This is a proposal for declassification pursuant to 10 C.F.R. 1045.20 
regarding information classified under the Atomic Energy Act.

We request that the Department of Energy initiate the declassification 
of the total size of the U.S. nuclear stockpile and the number of weapons 
dismantled annually as of the end of each fiscal year from FY 2010 
through FY 2013.

The Department has previously declassified such information for each 
fiscal year through FY 2009 (as per DOE Classification Bulletin WNP-128 
dated May 6, 2010).  Essentially, we are requesting that this 
declassification action be extended through the end of FY 2013.

The reasons for the proposed declassification are the same as the reasons 
for the Department's previous declassification of stockpile information:  
Nuclear transparency can strengthen non-proliferation efforts, and 
can lay a foundation for future arms control efforts.

Furthermore, as a matter of principle, information should remain 
classified only when doing so serves a valid and compelling national 
security purpose.  We suggest that continued classification of the 
size of the nuclear stockpile does not meet that criterion.

We therefore request that the Department consider declassifying this 
information, as provided in 10 C.F.R. 1045.20.

Thank you for your consideration.
