MEMORANDUM TO THE CHAIRMAN, DEFENSE SCIENCE BOARD<br />

SUBJECT: DSB Task Force Report on Assessment of Nuclear Monitoring and Verification<br />

Technologies<br />

The Undersecretary of Defense for Acquisition, Technology, and Logistics directed the Defense<br />

Science Board to form a Task Force to assess the needs for nuclear <strong>monitoring</strong> and verification<br />

technologies in support of future treaties and agreements. The Terms of Reference stipulated that the<br />

Task Force should:<br />

• Summarize future directions in nonproliferation and arms control treaties and agreements,<br />

including environment in which implemented<br />

• Project demands on, and assess capabilities of, International Atomic Energy Agency in next<br />

15-20 years with expected growth in nuclear power<br />

• Assess current and projected gaps in technical capabilities to support anticipated <strong>monitoring</strong><br />

and verification regimes<br />

• Identify promising adaptations from advances made for other purposes; e.g.,<br />

Close-in <strong>monitoring</strong> of targets in low signal/high clutter environments<br />

Nuclear forensics and attribution<br />

Stockpile stewardship<br />

Nuclear weapons effects<br />

Countering nuclear threats<br />

• Propose new initiatives where needed, to include RD&T, red/blue teaming<br />

• Perform a net assessment to help identify highest risks associated with potential technical<br />

implementation paths<br />

• Recommend [time-phased] programs for DOD, DOE, IC - separate and/or combined -<br />

include State, DHS, and others where appropriate<br />

Early in the study, the Task Force agreed that limiting its assessment to treaties and agreements<br />

alone, as the study’s sponsors anticipated at the beginning of the study, would miss the more<br />

challenging problem to national security, namely the growing threat of both vertical and horizontal<br />

nuclear proliferation, for which treaties and agreements are important, but not exclusive, mitigating<br />

mechanisms. The Task Force therefore expanded its scope to include a broader assessment of<br />

technical needs to support nuclear proliferation <strong>monitoring</strong> within both cooperative and unilateral<br />

constructs. The Task Force’s deliberations resulted in the following top level conclusions:<br />

1. The nuclear future will not be a linear extrapolation of the past. The nature of the problem is<br />

changing significantly in a number of dimensions:<br />

• The number of actors and geographic scope are becoming too large to anticipate within treaty<br />

sanctioned and national technical means (NTM) <strong>monitoring</strong> regimes alone;<br />

• Security risks from threshold states are growing;
