SUMMARY
OF U.S. NUCLEAR REGULATORY COMMISSION FLUENCE COMPUTATIONAL METHODOLOGY PUBLIC MEETING On May 24, 2018, the U.S. Nuclear Regulatory Commission (NRC) staff hosted a Category 2 public meeting with industry representatives. The participants included representatives from vendors, academia, National Laboratories and the Electric Power Research Institute (EPRI).
This meeting took place at the NRC Headquarters, Three White Flint North, 11601 Landsdown Street, North Bethesda, Maryland.
The purpose of this meeting was to facilitate an exchange of technical information about current NRC-sponsored research on neutron fluence computational methodology. The meeting summary, participants, agenda and presentation are provided in Enclosures 1, 2, 3, and 4, respectively.

U.S. Nuclear Regulatory Commission Public Meeting Summary May 25, 2018
Title:
Computation of Neutron Fluence Information Exchange Meeting Identifier: 20180227 Date of Meeting: May 24, 2018 Location: NRC Three White Flint North 11601 Landsdown Street, 1C03 Rockville MD Type of Meeting: Category 2 Purpose of the Meeting: To inform internal NRC stakeholders, industry, and the general public about current research on computational approaches to provide estimates of neutron fluence above and below the active core region.
General Details:
o Meeting participation was on-site, teleconference and GoToWebinar o There were 61 attendees o There were 23 NRC staff in attendance o There were approximately 38 members of the public representing 14 organizations o The meeting started at 1:30 PM and ended at 5:10 PM o Approximately 8 members of the public asked questions or made comments Summary of Presentations: Joel Risner (Oak Ridge National Laboratory) presented the current results of neutron fluence calculational methodology for both Boiling Water Reactors and Pressurized Water Reactors. He noted that the calculation of fluence levels outside the beltline region may be subject to phenomena that are not important for beltline region fluence calculations. The presentation discussed the analysis methodology for fluence calculations and presented the results of some parametric studies that illustrate effects of source, geometry, and materials that affect beyond the beltline fluence calculations in ways that they do not affected beltline region calculations.
Action Items/Next Steps:
o Schedule a public meeting for March 2019 Attachments:
o Meeting agenda o Attendees o Presentation slides
