The STARS Alliance
- 7 companies operate 13 nuclear units with over 15,000 MWe generating capacity
- AmerenUEs Callaway Station,
- Arizona Public Services Palo Verde Station,
- Luminants Comanche Peak Station,
- Pacific Gas & Electrics Diablo Canyon Station,
- Southern California Edisons San Onofre Station,
- STP Nuclear Operating Company
- Wolf Creek Nuclear Operating Corporation
- The alliance was formed to capitalize on the collective abilities of the seven companies to support each others efforts with three primary objectives: 1) achieving and maintaining operational excellence, 2) achieving effective industry influence, and 3) enhancing economic performance.

Plant Description & AMP Development August 16, 2010 Philippe Soenen
DCPP Basic Description
- The DCPP site consists of approximately 750 acres located in San Luis Obispo County, California
- Both DCPP Units employ a four-loop pressurized water reactor nuclear steam supply system furnished by Westinghouse Electric Corporation.
- The balance of plant for each Unit was designed and constructed by PG&E with the assistance of Bechtel.
- PG&E is authorized to operate Units 1 and 2 of the Diablo Canyon Power Plant, each at the licensed reactor core power level of 3,411 MWt (100 percent rated power).
- Current Operating Licenses expire in 2024 and 2025
- The plant incorporates two similar PWR nuclear power units, each consisting of an NSSS, turbine-generator, auxiliary equipment, controls, and instrumentation.
- Principal structures include the containment structures, turbine building, and auxiliary building (which includes the control room, the fuel handling areas, and the ventilation areas).
- The NSSS for each Unit is contained within a steel-lined reinforced concrete structure.

- Evaluated remaining OE for aging effect and/or AMP applicability
- Applicable corrective action documents (ARs, Notifications) are listed in Tab 2 the AMP Program Evaluation Reports (PERs)
- Significant plant OE searched for dates prior to 1997
- Additional word search using AMP specific terms using STARS/NRC audit search strings
- NCR, MR, Program Health Reports, Self/QA assessments
- Currently available in hardcopy PER binders
- Example: Boric Acid Corrosion OE Whitepaper -
