Phase II


This working group’s focus was to identify and advance a limited number of key verification technologies. These were based on findings from the three working groups in Phase I, where gaps were identified in the ability to detect and monitor a nuclear explosive device and its key components. Consideration was given to the development of information barriers to protect proliferation sensitive information. Further aspects of how such technologies can be trusted by both parties (authentication) was considered together with WGs 4 and 5, including how to meet safety and security requirements within nuclear and explosive facilities (certification). Possible development of nuclear weapon templates, including their feasibility and their uses, was also explored in greater depth.

The group undertook practical activities including developments and demonstrations. Such activities were a visible output from IPNDV, and enabled outreach and educational experiences.
