The NRC has previously granted approval of the initial evaluation for one fuel cycle by NRC letters dated April 1, 1994, and April 5, 1994.Approval of the Fracture Mechanics Evaluation and the In-Service Examination Plan is requested by July 1, 1995, to support the next Unit.2 Refueling Outage which is scheduled to start on September 25, 1995.FPL performed the evaluation of the pressurizer instrument nozzle flaws as described in IWB-3600.Based on the results of the evaluation, FPL has determined that the nozzles meet the acceptance criteria for continued service without the flaws being removed.Attachments A and B conclude that the nozzles are acceptable for an additional 30 years of plant life.The area containing the flaw will be periodically examined as described in Attachment C.Please contact us if there are any questions about this submittal.
