Within 60 days ofplant restartfollowing the next inspection of the Alloy 82/182/600pressurizer penetrationsand steam spacepiping connections, tile subject PJIR licensees should either:
(a) submit to the NRC a statement indicatingthat the inspections describedin the licensee 's response to item (1)(c) of this bulletin wvere completed and a description of the as-found condition ofthe pressurizershell, anyfindings of relevant indications of through-wall leakage,followvup NDE performed to characterizeflaws in leakingpenetrations or steam spacepiping connections, a stunmnar' of all relevant indicationsfoundby NDE, a sumnmnzay of the disposition of anyfindings of
boric acid, and an' corrective actions taken and/orrepairsmade as a result of the indications -
found, or (b) if the licensee was unable to complete the inspections describedin response to item (I)(c) of this bulletin, submit to the NRC a sunmmary of the inspectionsperformed, the extent of the inspections, the methods used, a description of the as-found condition of the pressurizershell, anyfindings of relevant indicationsof through-wall leakage, followuzp NDE performed to characterizeflawsin leakingpenetrationsor steam space piping connections, a sunimnaty of all relevant indications found by NDE, a sunmmary of the disposition of anyfindings of boric acid, and any corrective actions takeml and/orrepairsmade as a result of the indicationsfound. In addition, supplement the answver which you provided to item (J)(d) above to explain wh)y the inspections that you completed were adequateforthe purpose of maintainingthe integrity ofyourfacility's RCPB and for meeting all applicableregulatory requirements wt'hich pertain to yourfacility.
For lines attacheddirectly to the pressurizer, with the exception of the surge line, the information requested in (1) and (2) above should be providedfor any locations, including those remotefroln the pressurizershell, which contain Alloy 82/182/600 materials which are exposed to conditionssimilarto those of thepressurizerenvironment.
STPNOC Response:
-- STPNOC completed the Unit 1 12th Refueling Outage (1RE12) on April 16, 2005 and submits the information below describing the results of the Alloy 82/182 pressurizer penetration and steam space piping connection inspections.
STPNOC performed "Bare Metal Visual" (BMV) inspections on all steam space nozzles during the Unit I refueling outage (IRE12) in the Spring 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 BMV 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 nondestructive examination report was written to document these examinations. Similar inspections are scheduled for subsequent refueling outages.
