G-2 iii Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Executive Summary The purpose of this report is to provide information as requested by the Nuclear Regulatory Commission (NRC) in its March 12, 2012 letter issued to all power reactor licensees and holders of construction permits in active or deferred status. (Ref. 5) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 5)Following the accident at the Fukushima Dai-ichi nuclear power plant resulting from the March 11, 2011, Great Tohoku Earthquake and subsequent tsunami, the NRC established the Near Term Task Force (NTTF) in response to Commission direction.

The NTTF issued a report -Recommendations for Enhancing Reactor Safety in the 2 1 st Century: The Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident -that made a series of recommendations, some of which were to be acted upon "without unnecessary delay." (Ref. 6) On March 12, 2012, the NRC issued a letter to all power reactor licensees in accordance with 10CFR50.54(f).

The 50.54(f) letter requests information to assure that certain NTTF recommendations are addressed by all U.S. nuclear power plants. (Ref. 5) The 50.54(f) letter requires, in part, all U.S. nuclear power plants to perform seismic walkdowns to identify and address degraded, non-conforming or unanalyzed conditions and to verify the current plant configuration is within the current seismic licensing basis. This report documents the seismic walkdowns performed at Quad Cities Generating Station Unit 2 in response, in part, to the 50.54(f)letter issued by the NRC.The Nuclear Energy Institute (NEI), supported by industry personnel, cooperated with the NRC to prepare guidance for conducting seismic walkdowns as required in the 50.54(f) letter, Enclosure 3, Recommendation 2.3: Seismic. (Ref. 5) The guidelines and procedures prepared by NEI and endorsed by the NRC were published through the Electric Power Research Institute (EPRI) as EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near- Term Task Force Recommendation 2.3: Seismic, dated June 2012; henceforth, referred to as the "EPRI guidance document." (Ref. 1) Exelon/Quad Cities has utilized this NRC endorsed guidance as the basis for the seismic walkdowns and this report. (Ref. 1)The EPRI guidance document was used to perform the engineering walkdowns and evaluations described in this report. In accordance with the EPRI guidance document, the following topics are addressed in the subsequent sections of this report.* Seismic Licensing Basis* Personnel Qualifications

• Selection of Systems, Structures, and Components (SSC)* Seismic Walkdowns and Area Walk-Bys* Seismic Licensing Basis Evaluations

• IPEEE Vulnerabilities Resolution Report* Peer Review iv Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Seismic Licensing Basis The Seismic Licensing Basis is briefly described in Section 2 of this report. The safe shutdown earthquake for the Quad Cities Generating Station site is 0.24g horizontal ground acceleration and 0.16g vertical ground acceleration. (Ref. 2 section 3.7)Personnel Qualifications Personnel qualifications are discussed in Section 3 of this report. The personnel who performed the key activities required to fulfill the objectives and requirements of the 50.54(f) letter are qualified and trained as required in the EPRI guidance document.(Ref. 1) These personnel are responsible for:* Selecting the SSCs that should be placed on the Seismic Walkdown Equipment List (SWEL)," Performing the Seismic Walkdowns and Area Walk-Bys," Performing the seismic licensing basis evaluations, as applicable," Identifying the list of plant-specific vulnerabilities identified during the IPEEE program and describing the actions taken to eliminate or reduce them," Performing the peer reviews Selection of SSCs ,Selection of SSCs is discussed in Section 4 of this report. The process used to select the items that were included in the overall Seismic Walkdown Equipment List (SWEL) is described in detail in the EPRI guidance document, Section 3: Selection of SSCs. (Ref.1) The SWEL is comprised of two groups of items, which are described at a high level in the following subsections.

Sample of Required Items for the Five Safety Functions

-SWEL 1 Screen #1 narrowed the scope of SSCs in the plant to those that are designed to Seismic Category I requirements because they have a seismic licensing basis.Screen #2 narrowed the scope of SSCs by selecting only those that do not regularly undergo inspections to confirm that their configuration continues to be consistent with the plant licensing basis.Screen #3 narrowed the scope of SSCs included on SWEL 1 as only those associated with maintaining the five safety functions.

These five safety functions include the four safe shutdown functions (reactor reactivity control, reactor coolant pressure control, reactor coolant inventory control, and decay heat removal, which includes the Ultimate Heat Sink), plus the containment functions.

Screen #4 was a process intended to result in a SWEL 1 that sufficiently represented the broader population of plant equipment and systems needed to meet the objectives of the 50.54(f) letter. The following five sample attributes were used: " A variety of types of systems" Major new or replacement equipment* A variety of types of equipment* A variety of environments v

Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Equipment enhanced due to vulnerabilities identified during the IPEEE program Soent Fuel Pool Related Items -SWEL 2 Screen #1 and Screen #2 were used to narrow the scope of spent fuel pool related SSCs to those that have a seismic licensing basis and those that are appropriate for an equipment walkdown process. Screen #3 was a process intended to result in SWEL 2 that sufficiently represents the broader population of spent fuel pool Seismic Category I equipment and systems to meet the objectives of the 50.54(f) letter, and included the following sample selection attributes: " A variety of types of systems" Major new or replacement equipment* A variety of types of equipment* A variety of environments Screen #4 identified items of the spent fuel pool that could potentially cause a rapid drain-down of the pool, even if such items are not Seismic Category I. Rapid drain-down is defined as lowering the water level to the top of the fuel assemblies within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after the earthquake.

Any items identified as having the potential for rapidly draining the spent fuel pool were to be added to SWEL 2.For Quad Cities Unit 2, the SWEL is comprised of: " SWEL 1 resulted with 102 items for walkdown.* SWEL 2 resulted with no items for walkdown.* There are no SSCs associated with spent fuel pool rapid drain-down to be included on SWEL 2.Seismic Walkdowns and Area Walk-Bys Section 5, Appendix C, and Appendix D of this report documents the equipment Seismic Walkdowns and the Area Walk-Bys.

The online seismic walkdowns for Quad Cities Unit 2 were performed during the week of August 6, 2012. During the majority of the walkdown activities, the walkdown team consisted of two (2) Seismic Walkdown Engineers (SWEs), the station Lead Responsible Engineer (LRE) or designee, and a station Equipment Operator.The seismic walkdowns focused on the seismic adequacy of the items on the SWEL.The walkdowns focused on the following:

• Adverse anchorage conditions

• Adverse seismic spatial interactions

• Other adverse seismic conditions (e.g., degradation, configuration, etc.,)Area Walk-Bys were conducted in each area of the plant that contained an item on the SWEL (generally within 35 feet of the SWEL component).

The Area Walk-By was performed to identify potentially adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL item. The key examination factors that were considered in the Area Walk-Bys included the following:

vi Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169" Anchorage conditions (if visible without opening equipment)

• Significantly degraded equipment in the area" Potential seismic interaction

• A visual assessment (from the floor) of cable/conduit raceways and HVAC ducting (e.g., condition of supports or fill conditions of cable trays)" Potential adverse interactions that could cause flooding/spray and fire in the area* Other housekeeping items, including temporary installations The seismic walkdown team inspected 92 of the 102 components on the SWEL (comprised of SWEL 1 and SWEL 2). Walkdowns for 10 components were deferred due to accessibility issues such as being located in containment or energized equipment.

The 10 remaining Unit 2 items will be walked down during a unit outage or another time when the equipment is accessible, as appropriate.

Anchorage verification was required for a minimum of 27 components. (Ref. 1) A total of 36 anchorage configurations were confirmed to be installed in accordance with the station documentation.

Following the completion of the online seismic walkdowns, the industry was made aware that the NRC staff had clarified a position on opening electrical cabinets to inspect for other adverse seismic conditions.

Supplemental inspections of 18 electrical cabinets are planned and will be completed, as required, during a unit outage or another time when the equipment becomes accessible.

The list of electrical cabinets along with the milestone completion schedule is provided in Table E-2.During the seismic walkdowns at Quad Cities Unit 2 eighteen (18) Issue Reports (IRs)were issued for conditions such as open S-hooks and seismic housekeeping issues.Seismic housekeeping conditions were found to be the most common. After evaluation through the CAP, it was determined that none of the conditions identified in the IRs were adverse seismic conditions.

Seismic Licensing Basis Evaluations The EPRI guidance document, Section 5: Seismic Licensing Basis Evaluation provides a detailed process to perform and document seismic licensing basis evaluations of SSCs identified when potentially adverse seismic conditions are identified.

The process provides a means to identify, evaluate and document how the identified potentially adverse seismic condition meets a station's seismic licensing basis without entering the condition into a station's Corrective Action Program (CAP). In lieu of this process, Exelon/Quad Cities utilized the existing processes and procedures (Site CAP Expectations) to identify, evaluate and document conditions identified during the Seismic Walkdowns.

In accordance with Exelon/Quad Cities processes and procedures, all questionable conditions identified by the SWEs during the walkdowns were entered into the station CAP to be further evaluated and addressed as required.

The SWEs provided input to support the identification and evaluation (including seismic licensing basis evaluations, as required) of the potentially adverse seismic conditions entered into the CAP. The station corrective action program is a more robust process than that provided in'the EPRI guidance document; in part, ensuring each condition is properly evaluated for conformance with design and licensing bases and corrected as required.vii Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Conditions identified during the walkdowns were documented on the SWCs, AWCs, and entered into the CAP. Tables 5-2 and 5-3 in the report provide the IR, a summary of the condition, and the action completion status.IPEEE Vulnerabilities IPEEE vulnerabilities are addressed in Section 7 of this report. No vulnerabilities were identified as a result of the effort that addressed the Individual Plant Examination of External Events (IPEEE). (Ref. 3) However, plant improvements were identified in section 7 of Reference

3. Table G-1 provides the list of plant improvements, the IPEEE proposed resolution, the actual resolution and resolution date. All IPEEE improvement actions are complete.Peer Reviews A peer review team consisting of at least two individuals was assembled and peer reviews were performed in accordance with Section 6: Peer Reviews of the EPRI guidance document.

The Peer Review process included the following activities: " Review of the selection of SSCs included on the SWEL* Review of a sample of the checklists prepared for the Seismic Walkdowns and Area Walk-Bys* Review of licensing basis evaluations, as applicable

• Review of the decisions for entering the potentially adverse conditions into the CAP process* Review of the submittal report" Provided a summary report of the peer review process in the submittal report Section 8 of this report contains a summary of the Peer Review. The Peer Review determined that the objectives and requirements of the 50.54(f) letter are met. Further, the efforts completed and documented within this report are in accordance with the EPRI guidance document.Summary In summary, seismic walkdowns have been completed at the Quad Cities Generating Station Unit 2 in accordance with the NRC endorsed walkdown methodology.

All potentially degraded, nonconforming, or unanalyzed conditions identified as a result of the seismic walkdowns have been entered into the corrective action program.Evaluations of the identified conditions are complete and documented within the CAP.These evaluations determined the Seismic Walkdowns resulted with no adverse anchorage conditions, no adverse seismic spatial interactions, and no other adverse seismic conditions associated with the items on the SWEL. Similarly, the Area Walk-Bys resulted with no adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL item(s).The Seismic Walkdowns identified several minor issues predominantly pertaining to seismic housekeeping.

Other than these minor issues, the Seismic Walkdowns identified no degraded, nonconforming, or unanalyzed conditions that required either immediate or follow-on action(s).

No planned or newly identified protection or mitigation features have resulted from the efforts to address the 50.54(f) letter.viii Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Follow-on activities required to complete the efforts to address Enclosure 3 of the 50.54(f) letter include inspection of 10 items deferred due to inaccessibility along with supplemental inspections of 18 electrical cabinets.

Area Walk-Bys will be complete, as required, during these follow-on activities.

1.1 PURPOSE

The purpose of this report is to provide information as requested by the Nuclear Regulatory Commission (NRC) in its March 12, 2012 letter issued to all power reactor licensees and holders of construction permits in active or deferred status. (Ref. 5) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 5)

1.2 BACKGROUND

Following the accident at the Fukushima Dai-ichi nuclear power plant resulting from the March 11, 2011, Great Tohoku Earthquake and subsequent tsunami, the NRC established the Near Term Task Force (NTTF) in response to Commission direction.

The NTTF issued a report -Recommendations for Enhancing Reactor Safety in the 2 1 st Century: The Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident -that made a series of recommendations, some of which were to be acted upon "without unnecessary delay." (Ref. 6) On March 12, 2012, the NRC issued a letter to all power reactor licensees in accordance with 10CFR50.54(f).

The 50.54(f) letter requests information to assure that certain NTTF recommendations are addressed by all U.S. nuclear power plants. (Ref. 5) The 50.54(f) letter requires, in part, all U.S. nuclear power plants to perform seismic walkdowns to identify and address degraded, non-conforming or unanalyzed conditions and to verify the current plant configuration is within the current seismic licensing basis. This report documents the seismic walkdowns performed at Quad Cities Generating Station Unit 2 in response, in part, to the 50.54(f)letter issued by the NRC.The Nuclear Energy Institute (NEI), supported by industry personnel, cooperated with the NRC to prepare guidance for conducting seismic walkdowns as required in the 50.54(f) letter, Enclosure 3, Recommendation 2.3: Seismic.

(Ref. 1) Exelon/Quad Cities has utilized this NRC endorsed guidance as the basis for the seismic walkdowns and this report. (Ref. 1)1.3 PLANT OVERVIEW Quad Cities Generating Station consists of two operating boiling water reactor (BWR)generating units. The site is located in Rock Island County, Illinois, in parts of sections 7, 8, 17, 18, 19 and 20, Township; 20 North, Range; 2 East. It is on the east bank of the Mississippi River opposite the mouth of the Wapsipinicon River, and about three (3)1-1 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 miles north of Cordova, Illinois.

The site is about 20 miles northeast of the Quad Cities (Davenport, Iowa; Rock Island, Moline, and East Moline, Illinois). (Ref. 2 section 2.1.1)Both units have Mark I containments, are rated for 2957 MWt power (RENEWED FACILITY OPERATING LICENSE NO. DPR-29 (Unit 1) and DPR-30 (Unit 2)), and were originally designed and built by GE as prime contractor for Commonwealth Edison Company. The commercial service dates for Quad Cities Units 1 and 2 were February 18, 1973 and March 10, 1973 respectively. (Ref. 2 section 1.1.1)1.4 APPROACH The EPRI Seismic Walkdown Guidance is used for the Quad Cities Generating Station Unit 2 engineering walkdowns and evaluations described in this report. In accordance with Reference 1, the following topics are addressed in the subsequent sections of this report:* Seismic Licensing Basis* Personnel Qualifications

• Selection of SSCs* Seismic Walkdowns and Area Walk-Bys* Licensing Basis Evaluations

• IPEEE Vulnerabilities Resolution Report* Peer Review

1.5 CONCLUSION

Seismic walkdowns have been completed at the Quad Cities Generating Station Unit 2 in accordance with the NRC endorsed walkdown methodology.

All potentially degraded, nonconforming, or unanalyzed conditions identified as a result of the seismic walkdowns have been entered into the corrective action program.Evaluations of the identified conditions are complete and documented within the CAP.These evaluations determined the Seismic Walkdowns resulted with no adverse anchorage conditions, no adverse seismic spatial interactions, and no other adverse seismic conditions associated with the items on the SWEL. Similarly, the Area Walk-Bys resulted with no adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL item(s).The Seismic Walkdowns identified several minor issues predominantly pertaining to seismic housekeeping.

Other than these minor issues, the Seismic Walkdowns identified no degraded, nonconforming, or unanalyzed conditions that required either immediate or follow-on action(s).

No planned or newly identified protection or mitigation features have resulted from the efforts to address the 50.54(f) letter.Follow-on activities required to complete the efforts to address Enclosure 3 of the 50.54(f) letter include inspection of 10 items deferred due to inaccessibility along with supplemental inspections of 18 electrical cabinets.

Area Walk-Bys will be complete, as required, during these follow-on activities.

1-2 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 2 Seismic Licensing Basis 2.1 OVERVIEW This section of the report summarizes the seismic licensing basis for the Quad Cities Generating Station Unit 1 and Unit 2. The safe shutdown earthquake and a summary of the codes, standards, and methods used in the design of Seismic Category I SSCs are presented.

This section does not establish or change the seismic licensing basis of the facility and is intended to provide a fundamental understanding of the seismic licensing basis of the facility.2.2 SAFE SHUTDOWN EARTHQUAKE (SSE)The safe shutdown earthquake for the Quad Cities Generating Station site is 0.24g horizontal ground acceleration and 0.16g vertical ground acceleration. (Ref. 2 section 3.7)2.3 DESIGN OF SEISMIC CATEGORY I SSCs The input motions used to create the seismic design of Quad Cities are based on the Housner Ground Response Spectrum (GRS) and the south 80 degrees east (S80E)component of the 1957 San Francisco Golden Gate Park earthquake.

The Quad Cities drywell was evaluated using the results of the Dresden drywell analysis, which used the north-south component earthquake record of El Centro of May 18, 1940, normalized to 0.1Og for Operating Basis Earthquake (OBE (0.2g for Safe Shutdown Earthquake (SSE)). For the seismic analysis of the Seismic Class I structures and development of In-Structure Response Spectra (ISRS), the Housner GRS was used. (Ref. 2 section 3.7)The Golden Gate earthquake time history was used to verify that when using the time-history method, the maximum OBE loadings did not occur in the valleys of the unsmoothed (Golden Gate) spectrum.

The Quad Cities OBE is defined in the horizontal direction by the Housner GRS scaled to 0.12g peak ground acceleration (PGA) and the ISRS developed from the Golden Gate earthquake time history scaled to 0.12g. In addition, the OBE in the vertical direction is constant for all periods with a resulting PGA value of 0.08g. The Quad Cities SSE is defined by multiplying the OBE accelerations by a factor of 2, resulting in horizontal and vertical directions GRS PGA values of 0.24g and 0.16g respectively. (Ref. 2 section 3.7)The response spectrum method was used to calculate the buildings' responses.

For the Reactor Building, the SSE damping values used were 2% damping for steel and 5%damping for concrete.

For the Turbine Building, an SSE damping value of 5% was used.The peaks of the time history-derived spectra were broadened by 15%.

Tony Fuhs is the Operation Support Manager at Quad Cities Station, a formerly licensed SRO that has worked at Quad Cities Station for almost 30 years and is familiar with all aspects of the station operating procedures.

Various station personnel also provided support to the SWEL preparer in identifying major equipment or system modifications, equipment and systems located in different environments, and equipment and systems that would be accessible for inspection during the plant walkdowns, in accordance with Reference 1.3-2 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 4 Selection of SSCs 4.1 OVERVIEW This section of the report describes the process used to select structures, systems, and components, (SSCs) that were included in the Seismic Walkdown Equipment List (SWEL). The actual equipment lists that were developed in this process are found in Appendix B and are as follows: " Table B-Ia. Base List la -Items Exclusive to Unit 2* Table B-I b. Base List lb -Items Common to Units 1 and 2" Table B-2. SWEL 1 4.2 SWEL DEVELOPMENT The selection of SSCs process described in EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012, was utilized to develop the SWEL for Quad Cities Generating Station Unit 2. (Ref. 1)The SWEL is comprised of two groups of items:* SWEL 1 is a sample of items to safely shut down the reactor and maintain containment integrity* SWEL 2 is a list of spent fuel pool related items 4.2.1 SWEL 1 -Sample of Required Items for the Five Safety Functions The process for selecting a sample of SSCs for shutting down the reactor and maintaining containment integrity began with the composite Seismic Individual Plant Examination for External Events (IPEEE) Success Path Equipment List (SPEL). (Ref. 3)The IPEEE SPEL was then subjected to the following four screens to identify the items to be included on the first Seismic Walkdown Equipment List (SWEL 1): 1. Screen #1 -Seismic Category 1 As described in Reference 1, only items that have a defined seismic licensing basis are to be included in SWEL 1. Each item on the IPEEE SPEL was reviewed to determine if it had a defined seismic licensing basis. All items identified as Class I, as defined in Quad Cities UFSAR Chapter 3, were identified as having a defined seismic licensing basis. (Ref. 2) Electrical enclosures containing Class I electrical devices were identified as Class I. Class I determination was made through a review of current design and licensing basis documentation.

2. Screen #2- Equipment or Systems This screen narrowed the scope of items to include only those that do not regularly undergo inspections to confirm that their configuration is consistent with the plant 4-1 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 licensing basis. This screen further reduced the IPEEE SPEL of any Class I Structures, Containment Penetrations, Class I Piping Systems, cable/conduit raceways and HVAC ductwork.3. Screen #3 -Support for the Five Safety Functions This screen narrowed the scope of items included on the SWEL 1 to only those associated with maintaining the following five safety functions:

A. Reactor Reactivity Control (RRC)B. Reactor Coolant Pressure Control (RCPC)C. Reactor Coolant Inventory Control (RCIC)D. Decay Heat Removal (DHR)E. Containment Function (CF)The first four functions are associated with bringing the reactor to a safe shutdown condition.

The fifth function is associated with maintaining containment integrity.

As described in Reference 3, the safety function for each item on the IPEEE SPEL was identified.

It is noted that items on SWEL 1 with a specific safety function(s) are considered frontline systems. Items with a safety function of 'Auxiliary

&Support', 'Electrical Systems', or 'Racks & Panels' may be a frontline or support system. Items with a safety function of 'Auxiliary

& Support', 'Electrical Systems', or 'Racks & Panels' support at least one of the five safety functions however, the specific safety function(s) is not indicated as identification of the specific safety function(s) supported is not required by Reference 1.The resultant equipment list after Screen #3 is defined in the EPRI guidance document as Base List 1 and is included in Appendix B. (Ref. 1)4. Screen #4 -Sample Considerations This screen is intended to result in a SWEL 1 that sufficiently represents a broad population of plant Seismic Category I equipment and systems to meet the objectives of the NRC 50.54(f) letter. The following attributes were considered in the selection process for items included on SWEL 1: A. A Variety of Types of Systems The system is identified for each item on SWEL 1. The equipment included on SWEL 1 is a representative sample of several systems that perform one or multiple safety functions.

Further, the systems represented include both frontline and support systems as listed in Reference 1, Appendix E: Systems to Support Safety Function(s).

B. Major New and Replacement Equipment The equipment on SWEL 1 includes several items that have been modified or replaced over the past several years. Each item on SWEL 1 that is new or replaced is identified.

C. A Variety of Types of Equipment The equipment class is identified for each item-on SWEL 1. The equipment included on SWEL 1 is a representative sample from each of the classes of equipment listed in Reference I Appendix B: Classes of Equipment.

Where 4-2 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 appropriate, at least one piece of equipment from each class is included on SWEL 1.Screening

1. 1, #2, and #3 resulted in no equipment in the following classes:* (11) -Chillers* (13) -Motor Generators

• (19) -Temperature Sensors D. A Variety of Environments The location for each item is identified on SWEL 1. The equipment included on SWEL 1 is a representative sample from a variety of environments (locations) in the station.E. Equipment Enhanced Due to Vulnerabilities Identified During the IPEEE Program The equipment on SWEL 1 includes several items that were enhanced as a result of the IPEEE program. Each item on SWEL 1 that was enhanced as a result of the IPEEE program is identified.

F. Contribution to Risk In selecting items for SWEL 1 that met the attributes above, some items with similar attributes were selected based on their higher risk-significance.

To determine the relative risk-significance, the Risk Achievement Worth (RAW)and Fussell-Vesely importance for a Loss of Off-Site Power (LOOP) scenario from the internal plant PRA were used. Additionally, the list of risk-significant components for the LOOP PRA were compared with the draft SWEL 1 to confirm that a reasonable sample of risk-significant components (relevant for a seismic event) were included on SWEL 1. (Ref. 7)4.2.2 SWEL 2 -Spent Fuel Pool Related Items The process for selecting a sample of SSCs associated with the spent fuel pool (SFP)began with a review of the station design and licensing basis documentation for the SFP and the interconnecting SFP cooling system. (Ref. 2 section 9.1 and Refs. 8, 9, 10, &11) The following four screens narrowed the scope of SSCs to be included on the second Seismic Walkdown Equipment List (SWEL 2): 1. Screen #1 -Seismic Category I Only those items identified as Seismic Category I (having defined seismic licensing basis) are to be included on SWEL 2 with exception to the SFP structure.

As described in Reference 1, the adequacy of the SFP structure is assessed by analysis as a Seismic Category 1 (Class I) structure.

Therefore, the SFP structure is assumed to be seismically adequate for the purposes of this program and is not included in the scope of items included on SWEL 2.The review of design and licensing basis documentation for the SFP revealed no Class I equipment for Quad Cities Generating Station Unit 2. (Ref. 2 section 9.1 and Refs. 8, 9, 10, & 11)4-3 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Screen #1 resulted with no items added to SWEL 2. Therefore, Screens #2 and #3 below were not performed.

However, Screens #2 and #3 are provided for completeness as they are part of the equipment selection process.2. Screen #2 -Equipment or Systems This screen was to consider only those items associated with the SFP that were appropriate for an equipment walkdown process. This screen was not performed as Screen #1 resulted with no items added to SWEL 2.3. Screen #3 -Sample Considerations This screen represents a process that was intended to result in a SWEL 2 that sufficiently represents a broad, population of SFP Seismic Category 1 (Class I)equipment and systems to meet the objectives of the NRC 50.54(f) letter. (Ref. 1)The following attributes were to be considered in the development of SWEL 2: A. A Variety of Types of Systems B. Major New and Replacement Equipment C. A Variety of Types of Equipment D. A Variety of Environments This screen was not performed as Screen #1 resulted with no items added to SWEL 2.4. Screen #4 -Rapid Drain-Down This screen identifies items that could allow the spent fuel pool to drain rapidly.Consistent with Reference 1, the scope of items included in this screen is limited to the hydraulic lines connected to the SFP and the equipment connected to those lines. For the purposes of this program it is assumed the SFP gates are installed and the SFP cooling system is in its normal alignment for power operations.

The SFP gates are passive devices that are integral to the SFP. As such, they are considered capable of withstanding a design basis earthquake without failure and do not allow for a rapid drain-down of the SFP.The SSCs identified in this screen are not limited to Seismic Category I (having defined seismic licensing basis) items, but is limited to those items that could allow rapid drain-down of the SFP. Rapid drain-down is defined as lowering of the water level to the top of the fuel assemblies within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after the earthquake.

An assessment of the Quad Cities Generating Station Unit 2 spent fuel pools and their cooling systems was performed and found no SFP penetrations below 10 feet above the top of the fuel assemblies. (Ref. 2 section 9.1 and Refs. 8, 9, 10, & 11)As such, and consistent with Reference 1, there is no potential for rapid drain-down and no items were added to SWEL 2.4.2.3 SWEL 2- Conclusion No items were identified to be included in the scope of SWEL 2 for Quad Cities Generating Station Unit 2.4-4 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 5 Seismic Walkdowns and Area Walk-Bys 5.1 OVERVIEW Seismic Walkdowns and Area Walk-Bys were conducted by two (2) person teams of trained Seismic Walkdown Engineers (SWEs), in accordance with the EPRI guidance document during the week of August 6, 2012. The Seismic Walkdowns and Area Walk-Bys are discussed in more detail in the following sub-sections.

Consistent with the EPRI guidance document, Section 4: Seismic Walkdowns and Area Walk-Bys, the SWEs used their engineering judgment, based on their experience and training, to identify potentially adverse seismic conditions.

Where needed, the engineers were provided the latitude to rely upon new or existing analyses to inform their judgment.The SWEs conducted the Seismic Walkdowns and Area Walk-Bys together as a team.During the evaluations, the SWEs actively discussed their observations and judgments with each other. The results of the Seismic Walkdowns and Area Walk-Bys reported herein are based on the comprehensive agreement of the SWEs.5.2 SEISMIC WALKDOWNS The Seismic Walkdowns focused on the seismic adequacy of the items on the SWEL as provided in Appendix B of this report. It is noted, as discussed in Section 4 above, there were no items included on SWEL 2 for Quad Cities Unit 2. The Seismic Walkdowns also evaluated the potential for nearby SSCs to cause adverse seismic interactions with the SWEL items. The Seismic Walkdowns focused on the following adverse seismic conditions associated with the subject item of equipment:

• Adverse anchorage conditions" Adverse seismic spatial interactions

• Other adverse seismic conditions The results of the Seismic Walkdowns have been documented on the Seismic Walkdown Checklist (SWC) provided in the EPRI guidance document, Appendix C.Seismic Walkdowns were performed and a SWC completed for 92 of the 102 items identified on the Quad Cities Unit 2 SWEL. The completed SWCs are provided in Appendix C of this report. Additionally, photos have been included with most SWCs to provide a visual record of the item along with any comments noted on the SWC.Drawings and other plant records are cited in some of the SWCs, but are not included with the SWCs because they are readily retrievable documents through the station's document management system. Information on anchorage that was obtained from the previously performed Seismic Qualification Utility Group (SQUG) walkdowns are included in the SWCs since this information, in part, was used for the anchorage verification.

5-1 Quad Cities Generating Station Unit 2 12QO108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Seismic Walkdowns are deferred for the remaining 10 items to a unit outage or appropriate time when the equipment is accessible.

These items could not be walked down during the 180-day period following the issuance of the 10CFR50.54(f) letter due to their being inaccessible.

Inaccessibility of this equipment was either based on the location of the equipment (environment that posed personnel safety concerns while the unit is operating) or due to'the electrical safety hazards posed while the equipment is operating.

Appendix E of this report identifies the inaccessible equipment along with the plan for future Seismic Walkdowns.

The following subsections describe the approach followed by the SWEs to identify potentially adverse anchorage conditions, adverse seismic interactions, and other adverse seismic conditions during the Seismic Walkdowns.

5.2.1 Adverse

Anchorage Conditions Guidance for identifying anchorage that could be degraded, non-conforming, or unanalyzed relied on visual inspections of the anchorage and verification of anchorage configuration.

Details for these two types of evaluations are provided in the following two subsections.

The evaluation of potentially adverse anchorage conditions described in this subsection applies to the anchorage connections that attach the identified item of equipment to the civil structure on which it is mounted. For example, the welded connections that secure the base of a Motor Control Center (MCC) to the steel embedment in the concrete floor would be evaluated in this subsection.

Evaluation of the connections that secure components within the MCC is covered later in the subsection "Other Adverse Seismic Conditions." Visual Inspections The purpose of the visual inspections was to identify whether any of the following potentially adverse anchorage conditions were present:* Bent, broken, missing, or loose hardware 0 Corrosion that is more than mild surface oxidation 0 Visible cracks in the concrete near the anchors* Other potentially adverse seismic conditions Based on the results of the visual inspection, the SWEs judged whether the anchorage was potentially degraded, non-conforming, or unanalyzed.

The results of the visual inspection were documented on the SWC, as appropriate.

If there was clearly no evidence of degraded, nonconforming, or unanalyzed conditions, then it was indicated on the checklist and a licensing basis evaluation was not necessary.

However, if it was not possible to judge whether the anchorage is degraded, nonconforming, or unanalyzed, then the condition was entered into the Corrective Action Program as a potentially adverse seismic condition.

5.2.2 Configuration

Verification In addition to the visual inspections of the anchorage as described above, the configuration of the installed anchorage was verified to be consistent with existing plant documentation for at least 50% of the items on the SWEL.5-2 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Line-mounted equipment (e.g., valves mounted on pipelines without separate anchorage) was not evaluated for anchorage adequacy and was not counted in establishing the 50% sample size.Examples of documentation that was considered to verify that the anchorage installation configurations are consistent with the plant documentation include the following:

• Design drawings* Seismic qualification reports of analyses or shake table tests* IPEEE or USI A-46 program documentation, as applicable The Table C-1 of Appendix C indicates the anchorage verification status for components as follows: N/A: components that are line-mounted and/or are not directly anchored (with separate anchorage) to the civil structure and therefore do not count in the anchorage confirmation total Y: components that are anchored to the civil structure which were confirmed to be consistent with design drawings and/or other plant documentation N: components that are anchored to the civil structure for which anchorage drawings were not identified and/or retrieved See Table 5-1 below for the accounting of the 50% anchorage configuration confirmations, and the individual SWC forms in Appendix C for the specific drawings used for each anchorage verification confirmation.

Table 5-1. Anchorage Configuration Confirmation No. of SWEL N/A Items Required to SWEL Items Confirm? Items Confirmed (A) (B) (A-B)/2 Total 102 48 27 36 5.2.3 Adverse Seismic Spatial Interactions An adverse seismic spatial interaction is the physical interaction between the SWEL item and a nearby SSC caused by relative motion between the two during an earthquake.

An inspection was performed in the area adjacent to and surrounding the SWEL item to identify any seismic interaction conditions that could adversely affect the capability of that SWEL item to perform its intended safety-related functions.

The three types of seismic spatial interaction effects that were considered are:* Proximity* Failure and falling of SSCs (Seismic II over I)* Flexibility of attached lines and cables 5-3 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Detailed guidance for evaluating each of these types of seismic spatial interactions is described in the EPRI guidance document, Appendix D: Seismic Spatial Interaction.

The Seismic Walkdown Engineers exercised their judgment to identify seismic interaction hazards. Section 5.2.5 provides a summary of issues identified during the Seismic Walkdowns.

5.2.4 Other

Adverse Seismic Conditions In addition to adverse anchorage conditions and adverse seismic interactions, described above, other potentially adverse seismic conditions that could challenge the seismic adequacy of a SWEL item could have been present. Examples of the types of conditions that could pose potentially adverse seismic conditions include the following:

• Degraded conditions

• Loose or missing fasteners that secure internal or external components to equipment* Large, heavy components mounted on a cabinet that are not typically included by the original equipment manufacturer" Cabinet doors or panels that are not latched or fastened" Other adverse conditions Any identified other adverse seismic conditions are documented on the items' SWC, as applicable.

5.2.5 Issues

Identification during Seismic Walkdowns Table 5-2 provides a summary of issues identified during the equipment Seismic Walkdowns.

The equipment Seismic Walkdowns resulted in a total of eight (8) concerns identified and each of these was entered into the station's CAP. All of the identified concerns were assessed and it was concluded that the condition would not prevent the associated equipment from performing its safety-related function(s).

None of the conditions identified by the SWEs during the equipment Seismic Walkdowns were concluded to be adverse seismic conditions.

5.3 AREA WALK-BYS The purpose of the Area Walk-Bysl is to identify potentially adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL items. Vicinity is generally defined as the room containing the SWEL item: If the room is very large (e.g., Turbine Hall), then the vicinity is identified based on judgment, e.g., on the order of about 35 feet from the SWEL item.. This vicinity is described on the Area Walk-By Checklist (AWC), shown in Appendix D of this report. A total of 26 AWCs were completed for Quad Cities Unit 2. It is noted that additional AWCs will be completed, as required, as deferred and supplemental inspections are completed.

The key examination factors that were considered during Area Walk-Bys include the following:

• Anchorage conditions (if visible without opening equipment)

• Significantly degraded equipment in the area 5-4 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169* A visual assessment (from the floor) of cable/conduit raceways and HVAC ducting (e.g., condition of supports or fill conditions of cable trays)" Potentially adverse seismic interactions including those that could cause flooding, spray, and fires in the area* Other housekeeping items that could cause adverse seismic interaction (including temporary installations and equipment storage)" Scaffold construction was inspected to meet Exelon Procedure NES-MS-04.1, Seismic Prequalified Scaffolds" Seismic housekeeping was examined to meet station procedure MA-QC-716-026-1001, Seismic Housekeeping The Area Walk-Bys are intended to identify adverse seismic conditions that are readily identified by visual inspection, without necessarily stopping to open cabinets or taking an extended look. Therefore, the Area Walk-By took significantly less time than it took to conduct the Seismic Walkdowns described above for a SWEL item. If a potentially adverse seismic condition was identified during the Area Walk-By, then additional time was taken, as necessary, to evaluate adequately whether there was an adverse condition and to document any findings.The results of the Area Walk-Bys are documented on the AWCs included in Appendix D of this report. A separate AWC was filled out for each area inspected.

A single AWC was completed for areas where more than one SWEL item was located.Additional details for evaluating the potential for adverse seismic interactions that could cause flooding, spray, or fire in the area are provided in the following two subsections.

S-eismically-Induced Floodinaq/Spray Interactions Seismically-induced flooding/spray interactions are the effect of possible ruptures of vessels or piping systems that could spray, flood or cascade water into the area where SWEL items are located. This type of seismic interaction was considered during the IPEEE program. Those prior evaluations were considered, as applicable, as information for the Area Walk-Bys.One area of particular concern to the industry is threaded fire protection piping with long unsupported spans. If adequate seismic supports are present or there are isolation valves near the tanks or charging sources, flooding may not be a concern. Numerous failures have been observed in past earthquakes resulting from sprinkler head impact.Less frequent but commonly observed failures have occurred due to flexible headers and stiff branch pipes, non-ductile mechanical couplings, seismic anchor motion and failed supports.Examples where seismically-induced flooding/spray interactions could occur include the following:

• Fire protection piping with inadequate clearance around fusible-link sprinkler heads* Non-ductile mechanical and threaded piping couplings can fail and lead to flooding or spray of equipment* Long, unsupported spans of threaded fire protection pipi ng* Flexible headers with stiffly supported branch lines 5-5 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169* Non-Seismic Category I tanks The SWEs exercised their judgment to identify only those seismically-induced interactions that could lead to flooding or spray.Seismically-Induced Fire Interactions Seismically-induced fire interactions can occur when equipment or systems containing hazardous/flammable material fail or rupture. This type of seismic interaction was considered during the IPEEE program. Those prior evaluations were considered, as applicable, as information for the Area Walk-Bys.Examples where seismically-induced fire interactions could occur include the following:

0 Hazardous/flammable material stored in inadequately anchored drums, inadequately anchored shelves, or unlocked cabinets 0 Natural gas lines and their attachment to equipment or buildings* Bottles containing acetylene or similar flammable chemicals* Hydrogen lines and bottles Another example where seismically-induced fire interaction could occur is when there is relative motion between a high voltage item of equipment (e.g., 4160 volt transformer) and an adjacent support structure when they have different foundations.

This relative motion can cause high voltage busbars, which pass between the two, to short out against the grounded bus duct surrounding the busbars and cause a fire.The Seismic Walkdown Engineers exercised their judgment to identify only those seismically-induced interactions that could lead to fires.5.3.1 Issue Identification during Area Walk-bys Table 5-3 provides a summary of issues identified during the Area Walk-bys.

Ten (10)issues were identified during the Area Walk-Bys and entered into the station CAP. No potentially adverse seismic conditions were identified that resulted in a seismic licensing basis evaluation.

No seismically-induced flooding or spray interactions were identified during the Area Walk-Bys.

No seismically-induced fire interactions were identified during the Area Walk-Bys.5.4 SUPPLEMENTAL INFORMATION ON ELECTRICAL CABINET INSPECTIONS Following the completion of the online seismic walkdowns, the industry was made aware that the NRC had clarified a position on opening electrical cabinets to inspect for other adverse seismic conditions.

The purpose for opening these cabinets is to inspect for evidence of: " internal components not being adequately secured,* whether fasteners securing adjacent cabinets together are in place, and* other adverse seismic conditions.

Appendix E of this report includes Table E-2 which identifies components in the specified equipment classes that would be considered as electrical cabinets: 5-6 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 1. Motor Control Centers and Wall-Mounted Contactors

2. Low Voltage Switchgear and Breaker Panels 3. Medium Voltage, Metal-Clad Switchgear

4. Transformers

14. Distribution Panels and Automatic Transfer Switches 16. Battery Chargers and Inverters 20. Instrumentation and Control Panels Table E-2 indicates internal accessibility of each cabinet. Cabinets that have been identified as requiring these supplemental internal inspections are those with doors or panels with latches or thumbscrews and can be readily opened during normal maintenance activities.

Also provided for each cabinet is a proposed milestone schedule for performing these internal inspections and the associated station tracking record (IR number).Components identified on Table E-2 may also be identified on Table E-1 as items whose walkdowns have been deferred to an outage.The Seismic Walkdown Checklists (SWC) for the components identified in Table E-2 that can be opened for internal inspections will be revised at the time of the supplemental walkdown to indicate the results of these internal inspections.

Issues Identified During Seismic Walkdowns Actions Action Complete Item ID Description of Issue Request Yes/No ID (IR) (See Notes 1 & 2)Air line for associated solenoid valve 2-8801A-SO is in 8801A- contact with solid pipe insulation.

A drawing review 1397616 Yes 8AO shows that the valve fails closed upon loss of air.Therefore, there is no immediateseismic concern.During the Seismic Walkdowns it was identified that one of the two latches on MCC 29-1 was not secured. The other latch is secured. One of the two door latches was able to be secured properly.

The mass of the door is minimal with respect to the capability of the single door 2-7800- latch, and it is reasonable to conclude that the door will 29-1 remain closed during a seismic event. Further, the door 1397864 Yes is not made to be bolted shut, nor is it otherwise rigidly fastened to the cubicle. As such, it is not designed to provide significant reinforcement to the cubicle with regard to structural integrity during a seismic event.MCC 29-1 remains fully operable.No measures in place to prevent trolley on top of Switchgear 28 from impacting trolley rail end stops 2-7100- during seismic event, thereby introducing vibration into 28 Switchgear

28. Trolley movement and impact is judged to be minimal due to cyclic motion of seismic event and relatively small weight of trolley.During the Seismic Walkdowns it was identified that 2-8300- there is a minor bend in the bottom of the U2 125V 2 Battery Charger Door. Because the door is latched 1419533 No closed, there is no seismic interaction concern and the charger is capable of performing its design function..

One of 14 anchors is missing. Per Unit 1 enveloping SQUG anchorage analysis, minimum anchor safety 1/2- factor for a 14 anchor-configuration is greater than 9.6601 Therefore, a configuration with 1 anchor missing is 1398529 No judged to be acceptable.

U1 and U2 EDGs were walked down for extent of condition and were found to have all 14 anchor bolts installed.

5-8 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Actions Action Complete Item ID Description of Issue Request Yes/No ID (IR) (See Notes 1 & 2)Clearance issue between a portion of the valve actuator for the 2-0302-22A valve and an adjacent lifting lug.There is approximately 1/8th inch clearance between the lug and the valve component.

The location of the lug is away from the air input line and any moving parts associated with this valve. A drawing review (M-83, 2-0302- sheet 3) was performed and it was determined that the 1400097 No 22A valve fails closed. If contact is made between the lug and the actuator, and the actuator is damaged, the valve will fail closed per its design. Damage to the actuator will not affect the ability of the valve to fail closed. Because this valve is designed to isolate (fail closed, which is the safe condition), the safety function of the valve will not be prevented.

During Fukushima seismic walkdowns, it was discovered 2212- that 1 of the 26 sheet metal enclosure screws is missing 125 from the 1/2 EDG Engine Control Rack. The remaining 1400100 Yes 25 screws are judged adequate to maintain the connection.

Original SQUG Screening Evaluation Work Sheet (SEWS) incorrectly documented anchorage for the Ul/2 Diesel Day Tank. SEWS had referenced drawings associated with Ul and U2 Diesel Day Tanks, not U1/2 tank. UL/2 tank saddles are bolted to 18-inch I-beam, as are the U1 and U2 tanks. However, UL/2 I-beam is 1/2- anchored to floor slab with eight 7/8-inch anchor bolts instead of bolted to embedded beam with steel-to-steel 1402015 Yes bolts. Per drawings B-203 and B-204, anchors are hooked bolts installed per S&L Std. 1737. Hooked bolts are designed so as to develop the full strength of the anchor bolt. Hooked bolts are the same diameter and of the same number as the U1 and U2 tank steel-to-steel bolts, therefore the seismic qualification of the U1/2 tank anchorage is not impacted by judgment.Notes: 1) "Yes" indicates that any corrective actions resulting from the issue are complete 2) "No" indicates that any corrective actions resulting from the issue are NOT complete.

Actions are tracked by the IR number in the station Corrective Action Program.5-9 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Table 5-3. Issues Identified During Area Walk-Bys Actions Action Complete Item ID Description of Issue Request Yes/No ID (IR) (See Notes 1 &2)During the Seismic Walkdowns, it was identified that a light fixture near MCC 28-IA-1 (RB U2, EL 623, Col line N-8) had an open S-Hook on the North side of the fixture. However, the chain at the other end of the fixture AWC- had an S-Hook that was securely clamped shut.U2-2 Therefore, the fixture would not fall if the open S-Hook were to come loose. Additionally, there is sufficient clearance and other robust barriers (such as piping) that would prevent contact with the MCC should one end of the light fixture become unconnected.

During the Seismic Walkdowns, it was identified that the S-Hook used to secure a gas cylinder near the 2-8801A-AO valve is not closed. This item is located RB EL 623, AWC- near Col Line L-9. The unclosed S-Hook is a deficient 1397868 Yes U2-3 condition; however, the S-Hook is part of a chain assembly that is oriented horizontally and is installed taut such that during a seismic event it cannot become loose. Therefore there is no seismic interaction concern.Light fixture beam clamp oriented incorrectly.

Judged to AWC- maintain significant margin against falling during a 13'98051 Yes U2-8 seismic event based on low vertical seismic acceleration for Reactor Building and minimal weight of light fixture.Anchor strap for an instrument air line missing a bolt.AWC- Judged to be acceptable since no distortion observed at 1398048 Yes U2-8 support and air line spans to adjacent acceptable supports are short.Light fixture beam clamp oriented incorrectly on duct AWC- stiffeners above Bus 23. Judged to maintain significant U2-1 1 margin against falling during seismic event based on low 1398049 Yes vertical acceleration values and -minimal weight of light fixture.Light fixture behind Bus 2B-1 in the U2 Battery Charger Room is supported by S-Hooks which are not closed.This light fixture is hung from the ceiling. The edge of the light fixture is 5 inches from the wall and 17 inches AWC- from Bus 2B-1. The maximum horizontal movement due 1398046 Yes U2-12 to pendulum action is limited by the distance it can swing prior to contacting the wall (5 inches). Because the bus is at a distance much greater than 5 inches, the light fixture would not impact the bus, should the S-hooks unlatch during a seismic event.5-10 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 Actions Action Complete Item ID Description of Issue Request Yes/No ID (IR) (See Notes 1 &&2)Several overhead light fixtures with open S-Hooks.AWC- Various mitigating factors (fixtures near robust items, U2- other chains on fixture with closed S-hooks, fixture 1400098 No swing limited by hard targets, minimal fixture weight)prevent harmful interaction with soft targets.MSA SCBA cases on wall-mounted rack with lip to prevent sliding. Cases not strapped to rack. Per MA-QC-716-026-1001 (Seismic Housekeeping), the critical aspect ratio (height to least width) is 2.5 to 1 for AWC- overturning when the object is located on a fixed item. 1398527 Yes U2-26 The shelf is considered a fixed item based on the.mounting of the shelf to the structure.

These cases have an aspect ratio less that 2.5 to 1, therefore overturning is not of concern. Seismic storage of cases as described is adequate.During a walkdown with the resident inspector, it was identified that the recorder and cart for IRM 15 installed under WO 1542900-01 was not adequately located to AWC- prevent seismic interaction with the adjacent control U2-26 panel. The cart would slide on the floor even though the 1399135 Yes 2 wheels were locked as required by Procedure MA-QC-716-026-1001 for Seismic Housekeeping.

The cart did not maintain the 12" separation from the panel as required by Procedure MA-QC-716-026-1001.

During the Unit 2 seismic walkdowns, 9 housekeeping U2 -issues were found throughout the plant. Per procedure MA-QC-716-026-1001, staged materials near safety- 1400948 No related equipment must adhere to the listed requirements.

See IR for specific instances.

Notes: 1) "Yes" indicates that any corrective actions resulting from the issue are complete 2) "No" indicates that any corrective actions resulting from the issue are NOT complete.

Actions are tracked by the IR number in the station Corrective Action Program.5-11 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 6 Licensing Basis Evaluations The EPRI guidance document, Section 5: Seismic Licensing Basis Evaluation provides a detailed process to perform and document seismic licensing basis evaluations of SSCs identified when potentially adverse seismic conditions are identified.

The process provides a means to identify, evaluate and document how the identified potentially adverse seismic condition meets a station's seismic licensing basis without entering the condition into a station's Corrective Action Program (CAP). In lieu of this process, Exelon/Quad Cities utilized the existing processes and procedures (Site CAP Expectations) to identify, evaluate and document conditions identified during the Seismic Walkdowns.

In accordance with Exelon/Quad Cities processes and procedures, all questionable conditions identified by the SWEs during the walkdowns were entered into the station CAP to be further evaluated and addressed as required.

The SWEs provided input to support the identification and evaluation (including seismic licensing basis evaluations, as required) of the potentially adverse seismic conditions entered into the CAP. The station corrective action program is a more robust process than that provided in the EPRI guidance document; in part, ensuring each condition is properly evaluated for conformance with design and licensing bases and corrected as required.Conditions identified during the walkdowns were documented on the SWCs, AWCs, and entered into the CAP. Tables 5-2 and 5-3 in the report provide the IR, a summary of the condition, and the action completion status.6-1 Quad Cities Generating Station Unit 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 7 IPEEE Vulnerabilities Resolution Report Per the Individual Plant Examination of External Events (IPEEE) Submittal for Quad Cities and the Staff Evaluation Report of IPEEE submittal of Quad Cities Nuclear Power Station, Units 1 and 2 dated April 26, 2001, an explicit definition of vulnerability was not provided and no vulnerabilities with respect to potential severe accidents related to external events were identified. (Ref. 3 & 4) However, plant improvements and previously identified SQUG outliers were identified in Sections 3 and 7 of Reference 3.Table G-1 in Appendix G lists the plant improvements, the IPEEE/SQUG proposed resolution, the actual resolution and resolution date.
