ANS 2019 Summer Meeting

Minneapolis, MN• June 9-13, 2019

Rejuvenate Nuclear Technology Infrastructure and Facilities–Panel, Mon. pm
Session Organizers and Cochairs: Dustin Miller (Chase), Kevin H. Reynolds (Y-12)

There is an urgent need to rejuvenate and build the infrastructure, facilities, and skilled associated scientific staff involved in the research, testing, development, and deployment of advanced nuclear technologies. Maintaining this national testbed is critical to support vibrant commercial nuclear businesses. This panel will include speakers from government and private industry to speak to efforts ongoing in the United States that are attempting to address rejuvenation of infrastructure and facilities in the nuclear industry.

Panelists: David Kupferer (CNS) (135 downloads) , William R. Lonergan (CNS) (141 downloads) , Chris Crefeld (Westinghouse) (145 downloads) , Marilyn Kray (Exelon), Lou Martinez (Kairos Power) (134 downloads)

Credible Accident Sequences in NCS–Panel, Tues am
Session Organizer: Lon E. Paulson (GE Hitachi)
Chair: Thomas P. McLaughlin (LANL, ret.)

The purpose of this panel session is to provide practical examples of the determination of “credible” nuclear criticality accident sequences with fissionable materials in operations outside reactors. Panel to include NRC licensees, DOE facilities, or international fissionable material operations perspectives. A revisit of what constitutes a “credible” criticality accident sequence under current regulatory framework can improve facility operations, eliminate unnecessary controls, and permit focused attention on those that remain. Panelists should present and emphasize what constitutes a “credible” abnormal condition leading to a postulated nuclear criticality accident sequence or, alternatively, present what constitutes a “not credible” determination for a postulated criticality accident sequence. Practical applications may include existing fissionable material operations, storage, natural phenomena hazards (NPH), facilities undergoing decommissioning, new facilities under design and construction, CAAS system needs evaluation, or other. Credibility comes down to a shared belief between the analyst, the operator, and perhaps the regulator that there are enough barriers to assure ourselves that the credible [believable] scenarios have been prevented and enough controls and barriers are in place such that we render the sequence “highly unlikely.”

Panelists: Mandy Bowles Tomaszewski (LANL) (138 downloads) , David Erickson (SRNS) (136 downloads) , Jerry Hicks (DOE, retired) (130 downloads) , Deb Hill (NNL) (133 downloads) , Brandon O’Donnell (BWXT), Lon Paulson (GE Hitachi) (127 downloads) , Randy Shackelford (NFS) (138 downloads)

Real World Applications of Sensitivity/Uncertainty, Tues. pm
Session Organizer and Chair: Jennifer L. Alwin (LANL)

Operational Reviews: How Facilities Meet ANSI/ANS-8.1 Section 4.1.6–Panel, Wed. am
Session Organizer: Kristan M. Wessels (Y-12)
Chair: Amber J. McCarthy (Y-12)

This session addresses the different methods facilities use to perform their annual review of fissile operations required by ANSI/ANS-8.1 Section 4.1.6. Speakers will discuss topics including (but not limited to) which personnel participate in the operational reviews, the methods used to document the reviews, and how it is ensured that process drift is not occurring. Lessons learned and good practices associated with operational reviews will be discussed.

Panelists: Mandy Bowles Tomaszewski (LANL) (125 downloads) , David Erickson (SRS) (125 downloads) , Tom Young (Y-12) (117 downloads) , Nick Brown (BWXT) (132 downloads)

Sharing of Good Industry Practices and/or Lessons Learned in Nuclear Criticality Safety–Panel, Thurs. am
Session Organizer and Chair: Deborah Ann Hill (NNL)

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

Panelists: John Miller (SNL), Andrew Prichard (PNNL) (127 downloads) , Jennifer Alwin (LANL) (121 downloads) , Forrest Brown (LANL) (115 downloads) , Amber McCarthy (CNS) (119 downloads)
