4 PURPOSE
Purpose:
Provide the NRC staff an overview of a new and innovative risk-informed approach to aging management
- Answer questions and understand any concerns regarding the current risk-informed assessment scope for the Outdoor and Large Atmospheric Metallic Storage Tanks AMP
- Discuss potential expansion to other aging management programs
Background:
ENERCON prepared feasibility studies for a risk-informed aging management (RIAM) approach for inspections of outdoor and large atmospheric metallic storage tanks at Turkey Point and Point Beach
- Preliminary results show that the risk of extending the inspection intervals is very small
- An initial review of the licensing requirements indicates that the inspection changes can be implemented through the 50.59 process without submitting a LAR
5 OVERVIEW OF APPROACH Meet the RG 1.174 key principals for a risk-informed application
- Comply with current regulations
- Maintain defense-in-depth philosophy
- Maintain sufficient safety margins
- Keep any increases in risk small
- Monitor using performance measurement strategies RG 1.174 Guidelines for CDF/CDF and LERF/LERF
6 OVERVIEW OF APPROACH Risk-inform certain implementation details for a specific AMP
- Scope limited to internal tank inspections under GALL-SLR Revision 1 XI.M29, Outdoor and Large Atmospheric Metallic Storage Tanks AMP
- Determine tank inspections and inspection intervals based on the combination of risk insights, operating experience, and unique material/environment combinations
- Scope only affects SLR implementation activities and does not impact the SLR applications for PTN or PBN
7 OVERVIEW OF APPROACH Feasibility studies provide a preliminary assessment
- Review of OE to develop probability of loss of intended function for each tank
- PRA model used to assess risk impact from tank aging over the remaining life of the plant
- The risk impact from reducing tank inspections is very small (well within RG 1.174 Region 3)
- Assessment of licensing basis indicates that a 50.59 evaluation is the appropriate process for implementation
- Inspection plans can be modified over plant life based on OE and other factors to maintain low risk
8 NEXT STEPS Incorporate NRC feedback Complete technical evaluations with additional analysis of OE/data Perform 50.59 evaluations Incorporate relevant changes in UFSARs and AMP implementing activities
