INSPECTION VERIFICATION ITEMS FOR NEI LICENSE RENEWALDEMONSTRATION PROJECT
Dear Mr. Nelson:
By letter dated May 24, 2001, Nuclear Energy Institute (NEI) submitted sample sections todemonstrate the use of the Generic Aging Lessons Learned (GALL) report in preparing a license renewal application. The NRC staff is reviewing the information contained in these sample sections. The staff is also reviewing the NEI's response to the staff's request for additional information (RAI) submitted on July 11, 2001. As agreed, the staff review does not include Section 2 of the submitted samples because it relates to scoping and the GALL report is not a scoping document.The staff has identified specific items from the demonstration sections which should be verifiedby inspection as described in the enclosure. Please arrange to bring the necessary supporting documents which should contain information to respond to the enclosed list of sample inspection verification items to a public meeting at the NRC Headquarters. The exercise of the inspection verification activity as part of the demonstration project should provide the staff with an understanding of the supporting documentation that is normally maintained on site. Please contact S. K. Mitra at (301) 415-2783 to schedule the public meeting for the first week in September. Sincerely,/RA/Christopher I Grimes, Chief License Renewal and Standardization BranchDivision of Regulatory Improvement Programs Office of Nuclear Reactor RegulationProject No. 690
