Within 60 days ofplant restartfollowing the next inspection of the Alloy 82/182/600pressurizer penetrationsand steam spacepiping connections, the subject PWR licensees should either:
(a) submit to the NRC a statement indicatingthat the inspectionsdescribed in the licensee's response to item (1)(c) of this bulletin were completed and a descriptionof the as-found condition of the pressurizershell, anyfindings of relevant indicationsof through-wall leakage,followup NDE performed to characterizeflaws in leaking penetrationsor steam space piping connections, a summary of all relevant indicationsfound by NDE, a summary of the disposition of anyfindings of boric acid, and any corrective actions taken and/or repairsmade as a result of the indicationsfound, or (b) if the licensee was unable to complete the inspections described in response to item (1)(c) of this bulletin, submit to the NRC a summary of the inspectionsperformed, the extent of the inspections, the methods used, a descriptionof the as-found condition of the pressurizershell, anyfindings of relevant indicationsof through-wall leakage, followup NDE performed to characterizeflaws in leaking penetrationsor steam space piping connections, a summary of all relevant indicationsfound by NDE, a summary of the disposition of anyfindings of boric acid, and any corrective actions taken and/or repairs made as a result of the indicationsfound. In addition, supplement the answer which you provided to item (1)(d) above to explain why the inspections that you completed were adequatefor the purpose of maintainingthe integrity of yourfacility's RCPB andfor meeting all applicable regulatory requirements which pertain to yourfacility.
Forlines attacheddirectly to the pressurizer, with the exception of the surge line, the information requested in (1) and (2) above should be providedforany locations, including those remotefrom the pressurizershell, which contain Alloy 82/182/600 materialswhich are exposed to conditions similarto those of the pressurizerenvironment.
Response
STP Nuclear Operating Company (STPNOC) completed the Unit 2 11th Refueling Outage (2RE11) on October 31, 2005 and submits the information below describing the results of the Alloy 82/182 pressurizer penetrations and steam space piping connections inspections.
STPNOC performed bare metal visual inspections on all steam space nozzles during the Unit 2 refueling outage (2RE1 1) in the Fall of 2005. There was no evidence indicating any pressure boundary leakage from these nozzle safe ends of the pressurizer, nor was there any evidence of corrosion or wastage. A complete bare metal visual examination was achieved at each of the nozzle safe ends. A VT-I visual examination method was performed by a certified Level II visual examiner using a flashlight and an 18% neutral gray card with 1/32" width black line for assuring adequate lighting for resolution of any indications. A written nondestructive examination report was used to document these examinations. Similar inspections are scheduled for subsequent refueling outages.
