Licensing Principles

./ Power Uprate Group is incorporating lessons learned from recent submittals and from industry power uprate experience

  • Increased focus on LAR quality

-- Ensure adherence to L1C-109 acceptance review criteria Extensive use of independent third party review Plan for adequate NRC review time

  • Take advantage of lessons learned

--- Incorporate previous RAls as applicable

-- Power uprate lessons learned database for industry experience

-- Implement industry recommendations for excellence in performance of plant uprates (INPO 09-05, NEI 08-10)

  • Communicate with NRC

-- Effective pre-submittal meetings Routine communication with NRC Project Manager

-. Ensure reviewer issues resolved - raise concerns early Exel nco
