ANS 2017 Summer Meeting

San Francisco, CA • June 11-15, 2017

Data, Analysis and Operations in Nuclear Criticality Safety-I

Measurement of Delayed Neutron Group Parameters Using the Fission Burst of CFBR-II, Lingli Song, Chun Zheng (Inst. Nuclear Physics and Chemistry CAEP)

Criticality Scoping Calculations for a Multi-Function Dissolver Insert, Tracy Stover, Stephen Kessler (SRNS)

Bounding the Chemistry Conditions in the HM Solvent Extraction Process Criticality Safety Analyses, Tracy Stover, Stephen Kessler, John Lint (SRNS)

Moderation Control Challenges in a Shutdown Facility, Tom Hines (DOE), Matthew Wilson (Paschal Solutions Inc.)

A New Look at Historic CRAC “Divergence” Experiments-Implications for a CAAS Minimum Accident of Concern, Peter L. Angelo (Y-12 National Security Complex)

Considerations for Using FGE Conversion Factors in Type A Shipping Packages at the Savannah River Site, Brittany Williamson, James Baker (Savannah River Nuclear Solutions)

The Difficulty of Defining the Terms “Credible” and “Unlikely” for Nuclear Criticality Safety Purposes, Douglas G. Bowen (ORNL)

Sharing of Good Industry Practices and/or Lessons Learned in Nuclear Criticality Safety–Panel

Fundamental to the successful operation of any nuclear site is a first class safety culture which strives to continually improve in response to good industry practices and operating experience feedback. Speakers will provide examples of either specific good practices and/or lessons learned at their site, following which an audience discussion will be initiated on alternative good practices and experiences in these areas.

Panelists:

Deborah Hill (UK National Nuclear Laboratory),

John Miller (SNL),

Andrew Wysong (LANL),

Brandon O’Donnell (BWX Technologies),

Austin McGee (Y-12 National Security Complex)

Nuclear Criticality Safety Division Pioneer Discussion–Panel

Lawrence Livermore National Laboratory Criticality Safety personnel will give a series of presentations discussing the history of criticality safety experimentation and practice at LLNL. Topics discussed will include Project Pluto (a nuclear ramjet engine fielded at the Nevada test site by LLNL), criticality experimentation including the 1963 LLNL criticality accident, and early computational criticality safety.

Panelists:

David Heinrichs (LLNL),
