NNSA Administrator Frank Klotz was a featured speaker on June 22, 2015, at the fifth Comprehensive Nuclear Test-Ban Treaty (CTBT) Science & Technology Conference (SnT15) in Vienna, Austria. Over 1100 participants met to further strengthen the relationship between the international scientific and technological community with the Preparatory Commission for the CTBT Organization (CTBTO).  The Administrator’s remarks focused on multilateral collaboration on nuclear explosion monitoring, highlighting NNSA’s extensive collaboration with the CTBTO Preparatory Commission in all aspects of the international monitoring and verification regime. 

NNSA supports advancements in the International Monitoring System (IMS), supported by the International Data Centre, as it builds capacity to detect nuclear explosions at ever-decreasing yields.  In his speech, the Administrator’s offered to “facilitate making [NNSA’s] Nevada National Security Site available to future classes of CTBT inspectors in order to enrich their training and experience.”  This offer is a natural extension of NNSA’s strong support for the development of the CTBT’s on-site inspection capabilities, and will allow trainee inspectors, under carefully controlled conditions, to gain real world experience with a nuclear test site.

Over 40 NNSA experts from six DOE National Laboratories and NNSA Headquarters gave presentations on a wide range of topics, and two NNSA presentations were honored with awards. Walt Dekin of Lawrence Livermore National Lab (LLNL) won the Best Oral Presentation Award for "Understanding the Challenges of OSI Drilling to Safely Recover Relevant Radiological Samples from an Underground Nuclear Explosion.” Walt has extensive underground nuclear explosion monitoring experience and was a key inspection team leader at the 2014 CTBTO Integrated Field Exercise in Jordan. Sophie Guillon of France, who recently spent three months at LLNL won the Best Oral Presentation by a Young Scientist Award for "Variability in Sub-surface Gas Transport in the Light of Field Experiments and Numerical Modeling," co-authored with LLNL’s Charles Carrigan and Yunwei Sun.

While in Vienna, the Administrator met with CTBTO Executive Secretary Lassina Zerbo and several of his division directors, toured the International Data Centre and viewed radionuclide monitoring equipment at the Vienna International Centre (VIC). NNSA will continue its strong support for the CTBTO, and seek ways to further contribute to the improvement of its nuclear explosion monitoring and verification capabilities.
