| RAI B 3.7.1-X Background The license renewal application (LRA) states that aging management program (AMP) B.3.7, Buried Piping and Tanks Inspection Program, is a new program with one exception to the program elements in Generic Aging Lessons Learned (GALL) AMP XI.M34. This AMP addresses buried piping, i.e. piping in direct contact with soil. The description of the operating experience (OE) attribute for this AMP does not discuss specific OE at Duane Arnold Energy Center (DAEC) or from the industry. Instead, it states that "plant operating experience for this program will be gained as it is implemented during the period of extended operations, and will be factored into the program via the confirmation and corrective action elements of the DAEC 10 CFR 50 Appendix B quality assurance program."
| | Duane Arnold Energy Center cc: |
| The LRA also states that AMP B.3.21, External Surfaces Monitoring Program, is an existing program with enhancement. This AMP is also credited for managing the aging of the external surfaces of piping exposed to air.

| Issue There have been a number of recent industry events involving leakage from buried and underground piping, where the causes have included coating damage during backfill of piping, failure of fiberglass piping, failure of buried piping in and around piping penetrations, and failure of piping in trenches. In light of this recent industry OE, the staff is concerned about the susceptibility of buried and/or underground piping that are within the scope of 10 CFR 54.4 and subject to aging management for license renewal. In reviewing the AMP's cited above, along with the applicable aging management review items associated with them, the staff is not clear whether the components addressed by these AMPs would include both buried and underground piping (piping which is below grade and contained in a vault or other structure where it is exposed to air and where access is limited), and also if such programs would be sufficient and effective in managing the aging effects of buried and underground piping.

Box 14000 Juno Beach, FL 33408
DUANE ARNOLD ENERGY CENTER LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION RAI B 3.7.1-X
Background
The license renewal application (LRA) states that aging management program (AMP) B.3.7, Buried Piping and Tanks Inspection Program, is a new program with one exception to the program elements in Generic Aging Lessons Learned (GALL) AMP XI.M34. This AMP addresses buried piping, i.e. piping in direct contact with soil. The description of the operating experience (OE) attribute for this AMP does not discuss specific OE at Duane Arnold Energy Center (DAEC) or from the industry. Instead, it states that plant operating experience for this program will be gained as it is implemented during the period of extended operations, and will be factored into the program via the confirmation and corrective action elements of the DAEC 10 CFR 50 Appendix B quality assurance program.
The LRA also states that AMP B.3.21, External Surfaces Monitoring Program, is an existing program with enhancement. This AMP is also credited for managing the aging of the external surfaces of piping exposed to air.
Issue There have been a number of recent industry events involving leakage from buried and underground piping, where the causes have included coating damage during backfill of piping, failure of fiberglass piping, failure of buried piping in and around piping penetrations, and failure of piping in trenches. In light of this recent industry OE, the staff is concerned about the susceptibility of buried and/or underground piping that are within the scope of 10 CFR 54.4 and subject to aging management for license renewal. In reviewing the AMPs cited above, along with the applicable aging management review items associated with them, the staff is not clear whether the components addressed by these AMPs would include both buried and underground piping (piping which is below grade and contained in a vault or other structure where it is exposed to air and where access is limited), and also if such programs would be sufficient and effective in managing the aging effects of buried and underground piping.
Request Please provide information regarding how DAEC will incorporate the recent industry OE into its aging management reviews and programs in order to adequately and effectively manage the effects of aging, specifically for systems and components that are in scope for license renewal and include buried and underground piping.
