Backlighting identified nine(9) set screw gaps ranging from 12 to 35mils in width. Two reportable linearindications identified on one of two setscrew tack welds for Jet Pump Nos. 15(shroud-side) and 16 (vessel-side). Nine(9) auxiliary wedges installed on JetPumps 2, 3, 4, 6, 7, 8, 10, 12, and 14.

2008 EVT- 1, VT-3 visual examination of theVT-3 holddown beam for Jet Pump #8 was

performed in response to misalignmentconcerns raised during Unit 1 Recoveryand an RFI identified during the October2007 INPO BWRVIP Review Visit.There was a minor misalignment with thebeam but no relevant indications wereobserved.

VT-3 visual examination of sensing lineclamps installed during Unit 1 Recoveryon Jet Pumps 1-5 and 11-15 performed toconfirm that all of the repair hardware isin place and that the hardware has notshifted or changed from the as-installedcondition. No relevant indications wereobserved.

EVT- I visual inspection performed of acircumferential crack indication in thebacking ring for High Priority LocationDF-3 (Jet Pump # 19) to determine if theindication had increased in length. Thisindication was previously recordedduring Unit I Recovery and does notappear to have changed.

2008 VT- I Reinspection per BWRVIP-41 R 1: VT- Iof Medium Priority Location WD- I (JetPumps 1 thru 20) - No vibration-inducedwear noted. Indication of vertical wedgemovement at ten (10) locations wasobserved, but the movement markingsdid not appear to be recent and correlatedwith findings during the Unit 1 Recoveryexaminations. VT-I of Set ScrewLocations AS-I and AS-2 performed forJet Pumps 1 thru 20. Backlightingidentified no new set screw gaps.Inspection results identified eightapparently new set screw tack weldindications in addition to the two setscrew tack weld indications that werepreviously observed during Unit 1Recovery. Justification for ContinuedOperation (JCO) was prepared andconcluded that the jet pumps areacceptable as-is for one fuel cycle. Nine(9) auxiliary spring wedges installedduring Unit 1 Recovery were inspected toverify contact; no relevant indications

were observed.

2010 EVT-1 Reinspection per BWRVIP-41, Rev. 3:

EVT-1 of Medium Priority LocationsRS-8 and RS-9 (Jet Pumps 1 thru 20)performed in accordance with BWRVIPLetter No. 2009-202 ("Interim Guidancefor Accelerated Inspections of Jet PumpRiser to Riser Brace Welds andWedges"); no relevant indications.

EVT- 1 visual inspection performed of acircumferential crack indication in thebacking ring for High Priority LocationDF-3 (Jet Pump #19) to determine if theindication had increased in length. Thisindication was unchanged from UIR7.

wear noted; three new instances of minorwedge wear since UIR7 noted at JetPumps 1, 6, and 10 determined to be theresult of routing service during operation.VT-I of Set Screw Locations AS-I andAS-2 performed for Jet Pumps 1 thru 20.Backlighting identified one new setscrew gap (Jet Pump 20: Shroud-SideSet Screw - 17 mils). Evaluationperformed to provide one fuel cycle(U I C9) of continued operation.

Inspection results identified twoapparently new set screw tack weldindications on Jet Pump 17 in addition tothe nine set screw tack weld indicationsthat were previously observed duringU I R7 (NOTE: An indication that wasidentified during U1R7 for Jet Pump 14was accidentally counted twice).Justification for Continued Operation(JCO) was prepared and concluded thatthe jet pumps are acceptable as-is for onefuel cycle (UIC9).

*VT-2 leakage inspections have been and are performed on all RPV InstrumentationNozzles and Piping Nozzles each refuel outage. An enhanced leakage inspection isperformed on all locations to ensure no pressure boundary leakage. Inspections areperformed in the annulus area adjacent to the vessel skirt, and are perforned under vesselto ensure that any leakage identified is not from welded connections. Flange leakagefrom CRDM's is recorded, evaluated, and repaired if necessary. Mirror insulation isopened for SLC safe end inspection and for bottom head inspections but is not removedfrom other locations unless the leakage source can't be determined.
