CONSORTIUM FOR VERIFICATION TECHNOLOGYBACKGROUND
Technology-focused and mission-focused approach; CVT seeks to combine both; unique opportunities for synergisms given
diversity of 13 + 9 CVT partner institutions and groups
TWO WAYS OF APPROACHING THE VERIFICATION PROBLEM
POLICY RESEARCH THRUST: A TREATY ENABLING APPROACH
Emphasizes mission-focused dimension (as defined by existing and
expected future treaties); support and guide CVT technology developments
toward specific treaty applications; track emerging technologies

RELEVANT NUCLEAR ARMS CONTROL TREATIES
NUCLEAR NON-PROLIFERATION TREATYBans the acquisition of nuclear weapons by non-weapon states and commits the five weapon states to nuclear disarmament; verified by IAEA safeguards
Bans all nuclear explosions in all environments and would be verifiedby extensive verification mechanisms (International Monitoring System, CTBTO)
COMPREHENSIVE TEST BAN TREATY
At a minimum, treaty would ban fissile material production for weapons purposes; Issue about treaty scope: Would it also cover existing stocks?
FISSILE MATERIAL (CUTOFF) TREATY
NEXT-GENERATION NUCLEAR DISARMAMENT TREATIESAgreements that place limits on total number of nuclear warheads in arsenals would pose qualitatively new verification challenges

What are the expected (treaty) commitments and what are the political and technical concerns states may have with regard to possible
verification?
THE PROBLEM IN CONTEXT
MINDING THE GAPS
What are the key verification gaps, and how do they relate to important non-compliance scenarios? What are the main verification
concepts and technologies that might help address them?

CLOSING VERIFICATION GAPS ANDADDRESSING EMERGING CHALLENGES
Understanding the expected treaty commitments treaty is critical for exploring the potential role of different verification technologies and approaches
PROGRESS IN 2015–2016
Several new collaborations between research groups in different CVT thrust areas (involving both university partners and national laboratories)
Mapping Nuclear Verification as a tool to explore alternative and to facilitate discussions between thrust areas
Numerous promising technologies under development (as part of CVT and elsewhere); key is to understand how they can “fit into the big picture”
