Exelon Generation Company, L.L.C. Quad Cities Nuclear Power Station 300 Exelon Way Unit 2 Kennett Square, PA 19348 22710 206th Avenue North, Commercial Service Date March 10, 1973 Cordova, IL 61242 3.0 Abstract of Examinations, Conditions Noted and Corrective Measures 3.1.Section XI Examinations Summary A combination of ultrasonic (UT), liquid penetrant (PT), magnetic particle (MT) and visual (VT) testing were performed prior to and during the 2 1st refueling outage on ISI Program components.

Volumetric and surface examinations were compared with the recorded results of previous examinations for applicable Class 1, 2 and RI-ISI components. ISI inspections comprised of 33 volumetric (14 were RI-ISI, Category R-A welds), 9 surface examinations and 43 visual examinations were performed on Class 1, 2 and RI-ISI components. Four follow-up visual exams were due to recordable indications in one IWF-2500-1 components. One visual examination did not meet coverage requirements of ASME Section XI Code (i.e. greater than 90 percent of the specified examination volume) during Q2R21 and is listed in Table 3.1-1 B. Code cases used for ISI or Repair/Replacement activities are listed in the ISI Program Plan.

Pressure testing VT-2 examinations not related to repair/replacement activities are documented in Table 3.1-2 for third period exams. The Class 1 Vessel System Leakage Test, the Reactor Vessel Head Flange Seal Leak Detection System Test, and Partial Class 2 system leakage tests were performed on outage test blocks with the balance of the systems to be tested by the end of the period. The tests were performed in accordance with the 1995 Edition 1996 Addenda of the ASME Section XI Code.

Containment inspections were completed for Unit 2 for the second period of the 10-year interval in accordance with 2001 Edition through the 2003 Addenda of ASME Section XI Subsection IWE.

All disassembled bolting surfaces were examined as required.

Exelon personnel performed functional tests on a total of twenty-seven (27) snubbers for operability per the Service Life Monitoring/Failure Trending Sample and the 1995 edition through 1996 addenda of the ASME OM Code Subsection ISTD. Thirteen (13) snubbers were selected for the 10% sample group testing with the remaining fourteen (14) being tested for Service Life Monitoring. Seventeen (17) of the twenty-seven (27) snubbers were ASME Section XI Code designated. In addition, twenty-seven (27) replacement snubbers were tested and installed in accordance with a planned snubber replacement plan which is part of the Service Life Monitoring strategy. Of the fifty-four (54) snubbers tested, all were found to be acceptable for continued operation. Snubber testing activities are summarized in Table 3.1-3, "Quad Cities Unit 2 Snubber Functional Tests." Results are documented in WO 01333255.

Table 3.1-4 "Quad Cities Unit 2 Conditions Noted on ASME Code Components and Corrective Actions" summarizes the conditions noted during the examinations and corrective measures taken prior to returning the unit to service.

Table 3.3 identifies number and percentage of examinations completed in the fourth interval.

Quad Cities Nuclear Power Station 300 Exelon Way Unit 2 Kennett Square, PA 19348 22710 206th Avenue North, Commercial Service Date March 10, 1973 Cordova, IL 61242 3.2. BWRVIP-75-A/Generic Letter 88-01 Augmented examinations required by Generic Letter 88-01, "NRC Position on Intergranular Stress Corrosion Cracking (IGSCC) in BWR Austenitic Stainless Steel Piping" and BWRVIP-75-A, "BWR Vessel and Internals Project, Technical Bases for Revisions to Generic Letter 88-01 Inspection Schedules", were implemented in the this outage (Table 3.2-1). Six (6) Category C Welds (susceptible to IGSCC but mitigated by stress improvement) were examined. Four (4) of the Category C welds can be credited towards ASME Section XI examination percentages. Four (4) Category E Welds (cracked weldments that have been mitigated by a weld overlay) were examined. All welds were acceptable with no IGSCC indications. This is consistent with previous examination results.

3.3 In-Vessel Inspections (IVI)

Relief Request 14R-15 is approved as an alternative to Category B-N- I and B-N-2 requirements.

No Category B-N-1 or B-N-2 exams were scheduled during Q2R21.

Augmented examinations were preformed to implement additional BWRVIP requirements in accordance with the guidelines listed:

" Visual inspections of two Jet Pump Assembly riser brace attachment welds in accordance with BWRVIP-41 Rev 3

• Visual inspections Core Shroud Support Horizontal welds in accordance with BWRVIP-38

" Visual inspections of the Steam Dryer Wall Support Lugs (WSL) and RPV attachment welds in accordance with BWRVIP-48-A Previous acceptable indications on the Steam Dryer Wall Support Lugs (WSL) were re-examined for signs of change. No significant changes were noted in these indications. Quad Cities will continue to monitor this condition.

Component ID Description / Resolution Pressure Test During the Unit 2 Class I Leakage Test the listed components were identified to be leaking. Reference VT report # VT2-032 dated 4/4/2012 in Work Order 1359196. Corrective actions were taken as follows:

" IR's 1350193 identified a through wall leak (NI IB INSTR. NOZ) that was repaired and satisfactorily retested under WO 1529316

" IR's 1350195, 1350196, 1350174, 1350172, 1350190, 1350176, 1350169, 1350178 identify mechanical connection and packing leakage.

Mechanical Connections at CRD's Reference EC 389035 for evaluation of leakage through mechanical connections was acceptable.

CRD/HCUs - On Line bolted connection Reference EC 388738 for evaluation of leakage through mechanical connections was acceptable.

leakage for 3Yd period Visual Inspections 1265-M- 101 IR 1343011 written due to spring can hanger found outside design range. This hanger did not meet the acceptance standard of ASME Section XI, IWF-3410(a)(4). Corrective actions included re-setting of the spring can under WO 1524971 with satisfactory follow-up VT-3. In addition, scope expansion was performed to satisfy the requirements of ASME Section XI IWF-2430(a).

3953-M-343 (Class 3) IR 01340135 written due to rigid strut hanger found with a loose clamp. Although this appeared to be historic in nature as there was no evidence of thermal movement, this hanger did not meet the acceptance standard of ASME Section XI, IWF-3410(a)(2). Corrective actions included repair of hanger under WO 01523193 with satisfactory follow-up VT-3. In addition, scope expansion was performed to satisfy the requirements of ASME Section XI IWF-2430(a). As this is class 3, the follow-up exams would not be listed in table 3.1-IA.

'Note: Category B-G- I contains reactor vessel studs and nuts. 1/3 of the reactor vessel studs, nuts, bushings, washers, and ligaments are examined each period. Since the component number is repeated in this category, each period may result in greater than the limiting 2 percentage of exams.

Note: B-G-2 category includes bolted connections when components are opened as well as in place under tension.

3 Note: Category B-P and C-H exams are pressure tests tracked under Table 3.1-2.

4 Note: Exam Category B-A and B-O are scheduled to coincide with previous interval to maintain ten year interval between exams and are performed in accordance with IOCFR50.55a. Period completion percentage does not apply.

-Note: Categories B-L-2, and B-M-2 are inspected and credited under the Repair/Replacement Program only when the component is 6 disassembled. Only one of each type of valve and pump are required to be examined.

Note: Category F-A includes Class 1.2 and 3. There are 15 Class 3 hangers examined during Q2R21 that would not be listed in Table 3.1-1.

7 Note: Only 12 components are required to be examined in Category C-B, however several are 100% obstructed and are required to be examined every period by VT-2 in accordance with Item Number C2.33. Therefore, percentage completion for the interval by item number does not apply.

8 Note: B-N-I and B-N-2 Category Exams are credited by the performance of the BWRVIP program in accordance with Relief Request 14R-15.

9 Note: Category B-D is subject to Relief Request 14R- 17 which reduces the total number of examinations during the 10 year interval for the third period. Subsequently, the alternative to ASME Code provides an altemative completion percentage than originally scheduled.
