Quad Cities Nuclear Power Station 300 Exelon Way Unit 1 Kennett Square, PA 19348 22710 206"h Avenue North, Commercial Service Date February 18, 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 2 nd refueling outage on ISI Program components. Examinations were performed by General Electric Hitachi (GEH), URS Quality Programs, and Exelon Nuclear personnel. Volumetric and surface examinations were compared with the recorded results of previous examinations for applicable Class 1, 2 and RISI components. ISI inspections comprised of 31 volumetric (17 were RISI, Category R-A welds), 3 surface examinations and 59 visual examinations were performed on Class 1, 2 and RISI components. Of these 59 visual examinations, 41 were additional inspections due to IWF-2430(a) through (d) scope expansion requirements. There were 2 volumetric examinations that did not meet coverage requirements of ASME Section XI Code (i.e.

greater than 90 percent of the specified examination volume) during Q1R22 (Table 3. 1-IB).

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, "Quad Cities Unit 1 Pressure Testing Summary (4 th Interval)

Third Period". The Class I and 2 Vessel Leakage Tests were performed in accordance with the 1995 Edition 1996 Addenda of the ASME Code and applicable Relief Requests as listed in Table 3.1-2 for the third period of the fourth Interval.

Exelon personnel performed functional tests on a total of twenty-seven (27) snubbers for operability per the Service Life Monitoring/Failure Trending Sample and 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. Fifteen (15) of the twenty-seven (27) snubbers were ASME Section XI Code designated. In addition, twenty-four (24) 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-one (51) snubbers tested, none (0) were found to be unacceptable for continued operation. Snubber testing activities are summarized in Table 3.1-3, "Quad Cities Unit 1 Snubber Functional Tests (4 th Interval)".

Table 3.1-4, "Quad Cities Unit 1 Conditions Noted During ISI on ASME Code Components and Corrective Actions (4th interval)" summarizes the conditions noted during the examinations and corrective measures taken prior to returning the unit to service.

All eight Feedwater Sparger End Bracket pins were inspected during Q 1R22 as a follow-up to minor bracket wear from the pins identified during previous outages. The pinheads are wearing into the bracket hardware due to flow-induced vibration. No new or additional wear was noted in Q IR22. These indications are documented in IR 1488750 and evaluated as acceptable under EC 392703.

Core Spray piping welds were visually examined (19 visual exams). In this population were 3 welds with previously identified indications. Each of these indications was examined in Q1R22 with no apparent change in size. No additional indications were identified in the rest of the population. These indications are documented in IR 1489974 and evaluated under EC 392703.

Indications were observed in HAZ of Jet Pump 13/14 Riser pipe RS-2 weld during Q IR21 (2011). The weld was replaced with a mechanical repair clamp in Q1R22 under EC 385225 No changes was observed in the RS-2 indication from Q1R21 to Q1R22. The indications are documented in IR 1488705 and evaluated for continued service under EC 392703.

Multiple indications (gouges and rub marks) were identified on all four of the Steam Dryer wall support lugs. These indications were previously observed in Q1R21.

A comparison of the inspection results from Q 1R21 to Q IR22 found no apparent change to the previous indications and no new indications were identified. These indications are documented in IR 1488697 and evaluated for continued service under EC 392703 Indications were observed in HAZ of the Top Guide Rim weld. A total of 20 cell locations were inspected, with recordable indications observed in 6 of these cell locations. The indications are documented in IR 1490590 and evaluated for continued service under EC 392937.

Quad Cities will continue to monitor these conditions in accordance with the Reactor Internals Program.

'Note: Category B-G- I contains reactor vessel studs and nuts. 1/3 of the reactor vessel studs, nuts, 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 percentage of 2 exams.

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

3 4Note: Category B-P and C-H exams are pressure tests tracked under Table 3.1-2.

Note: Exam Category B-A and B-O are scheduled to coincide with previous interval to maintain ten year interval between exams and are 5 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: Only 69 total exams are required to meet combined Class I and 2 requirements for F-A category, however additional exams were scheduled to better distribute exams between systems and based on discovery of indications on Unit 2. Previous counts included the 7 scope expansion of several Class 1 hangers which artificially raised the inspection numbers for code credit.

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 exam population has been reduced as a result of Relief Request 14R-17.

'(Note: Category R-A exam population from the 2005B RISI Model requires 105 components be inspected in the 10-year interval. 114 Components are scheduled for examination to improve distribution by system. The distribution changes across the interval based on Risk Model updates.
