This letter provides corrections to information Entergy Nuclear Operations, Inc. (Entergy) previously submitted to the U.S. Nuclear Regulatory Commission (NRG) in letters dated July 31, 2006 (Reference 1), February 12, 2007 (Reference 2), and April 6, 2007 (Reference 3) relating to the Renewal Application for the James A. FitzPatrick Nuclear Power Plant (JAF) Facility Operating License. The information provided in the referenced letters is reflected in the License Renewal (LR) Safety Evaluation Report (SER) (Reference 4). The discrepancy between LR documentation and plant conditions
U.S. Nuclear Regulatory Commission Errors Identified in Response Provided to NRC during License Renewal Application Process July 11, 2017 Page2 was first identified by the NRC in January of 2017 during the R22 Refuel Outage and is the basis for an open Unresolved Item (URI 05000333/2017001-01 ), which is documented in the 102017 Quarterly Inspection Report (Reference 5). The original incorrect information along with the corrected response is provided in Attachment 1.
Exelon Generation Company, LLC believes that the erroneous information Entergy provided does not have a material impact on the effectiveness of the affected Aging Management Program. Specifically, the Containment lnservice Inspection (Cll) IWE Program is fully compliant with ASME Section XI requirements. This program requires augmented inspections of the interface between the drywall floor and drywell shell liner as described in IWE 1240. The augmented inspections have been completed as required during the period of extended operations. These inspections are required and performed regardless of whether a moisture barrier is installed or not.
Should you have any questions concerning this submittal, then please contact Christian Williams at 610-765-5729.
