Fuel Fabrication Industrys Response to Westinghouse Scrubber Condition and Use of Operating Experience Timothy Tate Fuel Cycle Information Exchange June 14, 2017 1

Overview Industry's Response to Westinghouse Scrubber Condition Timeliness Scope - Acute and Chronic Information Sources Communications Initial Actions Analyses/Inspections/Assessments Findings Industry's Use of Operating Experience and Continuous Improvement Initiatives 2

Industry's Response - Timeliness Licensees quickly became aware of condition Within day(s) of Westinghouse report to NRC Westinghouse report accessed by licensees via NRC website Westinghouse communicated to NEIs Fuel Operations Committee (FOC) members in timely fashion Enabled licensees to receive additional important and clarifying information Information updated and improved via FOC forum 3

Industrys Response - Scope

• Reviewed both acute and chronic material buildup potential - scrubbers, ducting, ventilation, equipment, etc.

• Reviewed active and legacy systems

• Applied questioning attitude regarding methods of detection/inspection

• Challenged existing analysis/insights 4

Industry's Response - Information Sources Immediate - Westinghouse was open and timely with information in an ongoing manner Ongoing - Licensees shared information via NEI FOC forum and bilateral communications NRC - Useful confirmatory information Via website reports Communications with Project Managers, Inspectors Follow-up augmented inspections and results 5

Industry's Response - Communications Started with Westinghouse formal report to NRC and informally with industry via NEI FOC Licensees initiated communications within their own Safety Organization and Management Licensee continued communications driven by their own methods via Corrective Action Program (CAP),

Safety Bulletins, Safety Meetings, Analysis/Results of Assessments Management reviews, all employee meetings, targeted reinforcement/improvements of information or methods applicable, procedure/program improvements as appropriate 6

Industry's Response - Initial Actions Immediately considered initial information Reviewed their own practices and results Inspections both visual and using NDA methods ISA treatment and accident scenarios/IROFS Initiated additional inspections in some cases Conducted internal communications involving:

Safety organization - Criticality Safety, ISA, etc.

Management and Operations Initiated Corrective Action Reports 7

Industry's Response -

Analyses/Inspections/Assessments Reviews of Existing Programs:

• Used existing Programs to monitor areas of potential accumulation of material

• Used Safety Culture attributes of self checking and procedural adherence with questioning attitude

• Discussed methods with other licensees via NEI FOC

• Reviewed historical performance and findings of past inspections

• Reviewed scope of inspections and broadened in some cases 8

Industry's Response -

Analyses/Inspections/Assessments Performed additional inspections as determined by review of program and condition information Reviewed Integrated Safety Analysis insights Performed self assessments Continued to use CAP to document findings as appropriate Cooperated fully with NRC inspections and inquiries 9

Industry's Response - Findings No additional findings of unexpected material buildups Reinforcement of Program and Procedural adherence Revalidation of ISA treatments and results No major program changes warranted 10

Industry's Use of Operating Experience All licensees strive to apply Safety Culture attributes to its operation - includes but not limited to:

CAPs Self checking Benchmarking Questioning attitude Open Communications - Internal and External Internal employee and management meetings NEIs FOC Fuel Cycle Facility Benchmarking Group NRC and Professional Societies, e.g. ANS, etc.

11

Industry's Use of Operating Experience Analyses using established methods and techniques Integrated Safety Analysis - What if?, HAZOP Self assessments including formal Root Cause Analysis CAP Trending analysis Risk or significance assessments 12

In Summary Industrys response to the Westinghouse scrubber condition has been thorough; and Industry carefully analyzes, develops and implements lessons-learned from operational events at fuel cycle facilities regardless of where they occur.
