G-2 iii Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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. 8) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 8)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 21st 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. 10) 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. 8) 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 Byron Generating Station Unit 1 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. 8) 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/Byron 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 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 Seismic Licensing Basis The Seismic Licensing Basis is briefly described in Section 2 of this report. The maximum horizontal and vertical ground accelerations at the foundation level are 20% of gravity for the safe shutdown earthquake (SSE). (Ref. 2, section 3.7.1.1)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 I 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
Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 Equipment enhanced due to vulnerabilities identified during the IPEEE program Spent 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 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.
Any items identified as having the potential for rapidly draining the spent fuel pool were to be added to SWEL 2.For Byron Unit 1, the SWEL is comprised of: " SWEL 1 resulted with 106 items for walkdown.* SWEL 2 resulted with 21 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 Byron Unit 1 were performed during the weeks of August 6 and August 20, 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), a station Equipment Operator, and a station Operations person. The outage walkdowns occurred on September 19 and 22, 2012 with a similar walkdown team.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 vi Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 located in the vicinity of the SWEL item. The key examination factors that were considered in the Area Walk-Bys included the following:
- 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 walked down 127 of the 127 components on the SWEL.For Byron Unit 1, anchorage verification was required for minimum of 38 components to meet the 50% verification requirements of the EPRI guidance document. (Ref. 1) A total of 45 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 45 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 Byron Unit 1 twenty-four (24) Issue Reports (IRs) were issued for conditions such as open fluorescent light fixture S-hooks and cracks in grout pads. Open fluorescent light fixture S-hook 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.
Through the efforts of the seismic walkdowns and development of this report, IR 1431416 was initiated to share lessons learned with various workgroups across the station. In particular, the IR was issued to create an action to tailgate lessons learned with Electrical Maintenance, Electrical Maintenance Work Planning, and the Maintenance Contractor.
The focal point of the lessons learned is in regards to open fluorescent light fixture S-hooks. The expected S-hook configuration is that they are closed sufficiently to prevent the support chain links from passing though the S-hook up to metal-to-metal contact.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/Byron utilized the existing processes and procedures (Site CAP Expectations) to identify, evaluate and document conditions identified during the Seismic Walkdowns.
vii Byron Generating Station Unit I 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 In accordance with Exelon/Byron 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 CAP 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. For those conditions that required it, seismic licensing basis evaluations were completed and documented within the IR. 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 and Appendix G 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 plant improvements'and associated 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 0 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, it was concluded by the peer reviews that the efforts completed and documented within this report are in accordance with the EPRI guidance document.Summary In summary, seismic walkdowns have been performed at the Byron Generating Station Unit 1 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 CAP.Evaluations of the identified conditions are complete and documented within the CAP.These evaluations determined the Seismic Walkdowns resulted with no adverse viii Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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 conditions predominantly pertaining to cracks in grout pads and open fluorescent light fixture S-hooks. Other than these minor conditions, the Seismic Walkdowns identified no degraded, nonconforming, or unanalyzed conditions that required either immediate or follow-on action. 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 supplemental inspections of 45 electrical cabinets.
Area Walk-Bys will be complete, as required, during these follow-on inspections.

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. 8) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 8)
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. 10) 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. 8) 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 Byron Generating Station Unit 1 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. 8) 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/Byron has utilized this NRC endorsed guidance as the basis for the seismic walkdowns and this report. (Ref. 1)1.3 PLANT OVERVIEW The Byron Station nuclear power plant consists of two nearly identical generating units, and two pressurized water reactors (PWR) Nuclear Steam Supply System (NSSS) and turbine-generators furnished by Westinghouse Electric Corporation (Westinghouse).(Ref. 2 section 1.1)1-1 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 The Byron Station Units 1 and 2 are rated at a Licensed power level of 3586.6 MWt.(Operating License; Unit 1 License No. NPF-37 and Unit 2 License No. NPF-66)The reactor containments are of post-tensioned concrete construction with a carbon steel liner. Sufficient free volume is provided to contain the energy released in a major accident without need for "pressure suppression" devices. Sargent & Lundy was responsible for containment design. (Ref. 2 section 1.1)Byron Station is located in north central Illinois, near the town of Byron and near the Rock River. Cooling for the plant is provided by two natural draft cooling towers for nonessential service water cooling, and by mechanical draft cooling towers for essential service water cooling. The fuel loading dates for the two.units were November 1984 and November 1986 for Units 1 and 2, respectively.
The corresponding dates for commercial operation were September 1985 and August 1987. (Ref. 2 section 1.1)1.4 APPROACH The EPRI guidance document is used for the Byron Unit 1 engineering walkdowns and evaluations described in this report. (Ref. 1) 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 performed at the Byron Generating Station Unit 1 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 (CAP).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 conditions predominantly pertaining to cracks in grout pads and open fluorescent light fixture S-hooks. Other than these minor conditions, the Seismic Walkdowns identified no degraded, nonconforming, or unanalyzed conditions that required either immediate or follow-on action. No planned or newly identified protection or mitigation features have resulted from the efforts to address the 50.54(f) letter.1-2 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 Follow-on activities required to complete the efforts to address Enclosure 3 of the 50.54(f) letter include supplemental inspections of 45 electrical cabinets.
Area Walk-Bys will be complete, as required, during these follow-on inspections.
1-3 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 2 Seismic Licensing Basis 2.1 OVERVIEW This section of the report summarizes the seismic licensing basis for the Byron 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 maximum horizontal and vertical ground accelerations at the foundation level are 20% of gravity for the safe shutdown earthquake (SSE). (Ref. 2, section 3.7.1.1)2.3 DESIGN OF SEISMIC CATEGORY I SSCs A full description of the Safe Shutdown Earthquake along with the codes, standards, and methods used in the design of the Seismic Category I SSCs for meeting the seismic licensing basis requirements is provided in the following Byron Station UFSAR sections:* 3.2 Classification of Structures, Components, and Systems* 3.7 Seismic Design* Attachment 3.7A -Reevaluation and Validation of the Byron/Braidwood Seismic Design Basis* 3.8 Design of Category I Structures
- 3.9 Mechanical Systems and Components
- 3.10 Seismic Qualification of Seismic Category I Instrumentation and Electrical Equipment
3.2 Classification
of Structures, Components, and Systems These UFSAR sections should be referred to for a detailed understanding of the seismic licensing basis.Summary of Seismic Design The UFSAR is a jointly reviewed document and thus is referenced as Byron/Braidwood UFSAR.The site response spectra, which are defined at the ground surface, are given in UFSAR Subsection 2.5.2 and are shown in UFSAR Figures 2.5-40 and 2.5-41 for the Byron site.Foundation level response spectra and time histories were generated by a deconvolution procedure described in UFSAR Subsection 3.7.1.2. The maximum horizontal and vertical ground accelerations at the foundation level are 20% of gravity for the safe shutdown earthquake (SSE) and 9% of gravity for operating basis earthquake (OBE).2-1 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 The comparisons between the free field seismic design motion applied at the surface and the corresponding foundation (rock) spectra for 2%, 3%, 4%, 5%, and 7% damping ratios are shown in UFSAR Figures 3.7-1 through 3.7-20 for the Byron site.During the review of the FSAR for an Operating License, the Byron/Braidwood seismic design was reevaluated using the Regulatory Guide 1.60 spectra without the application of a deconvolution analysis.
UFSAR Attachment 3.7A contains the specific NRC questions/responses on seismic design. These questions and responses document the historical evolution of certain aspects of the Byron/Braidwood seismic design. UFSAR Attachment 3.7A also provides the details and results of this reevaluation.
The UFSAR concludes that the present seismic design of Byron/Braidwood is conservative.
Based on the reevaluation described in UFSAR Attachment 3.7A, the Byron/Braidwood seismic design basis is acceptable and will therefore be used for all future seismic evaluations.
Seismic Class I structures are designed for seismic forces calculated from the aforementioned spectra using a response spectrum method of analysis.
The directional combination rule uses three components of earthquake motions (two horizontal directions with vertical direction) combined by the square-root-sum-of-the-squares (SRSS) method. For evaluation of Seismic Class I components, In Structure Response Spectra (ISRS) are used. For horizontal directions, ISRS are generated using an input acceleration time history at the base (foundation) of mathematical models that represent the plant structures.
To determine the foundation (rock) level motion, the soil rock profile above the foundation was modeled as a one-dimensional continuous shear layer system. The ground surface spectra consistent time histories were applied at the ground surface and the foundation level motion was obtained using the SHAKE program. For all of the structures founded on rock, the foundation level motion was used directly to excite the fixed base model.Summary of Codes and Standards The information presented below has been extracted from section 3.8 of Reference 2.This section summarizes the codes, specifications, standards of practice, and other accepted industry guidelines which are adopted to the extent applicable, in the design and construction of the following:

The actual equipment lists that were developed in this process are found in Appendix B and are as follows:* Table B-I, Base List I* Table B-2, Base List 2* Table B-3, SWEL 1 o Table B-4, SWEL 2 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 list for Byron Generating Station Unit 1. (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 9 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)At the request of Byron personnel, the Diesel Driven Essential Service Water Make-Up Pumps and representative supporting Seismic Category I components located in the River Screen House were added to the SPEL. The resulting amended 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 amended IPEEE SPEL was reviewed to determine if it had a defined seismic licensing basis. All items identified as Safety Category I, as defined in Byron UFSAR Chapter 3, were identified as having a defined seismic licensing basis. Electrical enclosures containing Class I E devices were identified as Safety Category I. Safety Category I and Class 1 E 4-1 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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 licensing basis. This screen further reduced the amended IPEEE SPEL of any Safety Category I Structures, Containment Penetrations, Safety Category 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 Appendix E of Reference 1, 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 designation of 'Support System HVAC', 'Support System AC Power', 'Support System DC Power', 'Engineered Safety Features Actuation System' (ESFAS) or'Cooling Water' may be a frontline or support system. Items with a safety function designation of 'Support System HVAC' (SSHVAC), 'Support System AC Power'(SSAC), 'Support System DC Power' (SSDC), 'Engineered Safety Features Actuation System' (ESFAS) or 'Cooling Water' (UHS) 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) 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 1 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).

Major new and replacement equipment The equipment included 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 1 Appendix B: Classes of Equipment.
Where appropriate, at least one piece of equipment from each class is included on SWEL 1.Screening
- 1, #2, and #3 resulted in no equipment in the following classes:* (12) Air Compressors
- (13) Motor Generators.
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 included 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. 11)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. 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 1 (Safety Category I) 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 structure.
Therefore, the SFP structure is assumed to be 4-3 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 seismically adequate for the purposes of this program and is not included in the scope of items included on SWEL 2.Per the Byron UFSAR Chapters 3 and 9, portions of the SFP SSCs are classified as Safety Category I and are screened into the SWEL 2 list. These Safety Category I SSCs include; the Spent Fuel Pit Heat Exchanger, Spent Fuel Pit Pump, Refueling Water Purification Pump OA, associated instrumentation, piping and manual/check valves. Note, these pump's motors are Safety Category II, even though the Refueling Water Purification Pump OA has an ESF power source. There are no Motor, Air or Fluid operated valves in the Safety Category I SSC flow paths.2. Screen #2 -Equipment or Systems This screen considers only those items associated with the SFP that are appropriate for an equipment walkdown process.3. Screen #3 -Sample Considerations This screen represents a process that is intended to result in a SWEL 2 that sufficiently represents a broad population of SFP Seismic Category 1 equipment and systems to meet the objectives of the NRC 50.54(f) letter. The following attributes were considered in the development of SWEL 2: A. A variety of types of systems The system is identified for each item on SWEL 2. The equipment included on SWEL 2 is a representative sample of the systems associated with the SFP and its cooling system.The SFP pump, Refueling Water Purification Pump OA, and SFP heat exchanger are included in the SWEL2 list.

The manual and check valves are included in the "(0) Other" class.D. A variety of environments The location for each item is identified on SWEL 2. The equipment included on SWEL 2 is a representative sample from a variety of environments (locations) for equipment associated with the SFP and its cooling system. All items are in the Auxiliary Building or Fuel Handling Building.4-4 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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 1 (Safety Category I) 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.
Excerpts from the Byron UFSAR 9.1.3.2 System Description document the design features which preclude rapid drain down of the Spent Fuel Pit.The Safety Category I spent fuel pool cooling system shown in Drawing M-63 consists of two complete cooling trains. The spent fuel pool cooling system (piping, pumps, valves, and heat exchangers) is Safety Category I, Quality Group C. The 3-inch piping from the refueling water storage tanks to the refueling water purification pump, the pump, and its associated piping and valves are Safety Category I, Quality Group C. A 2-inch Safety Category I, Quality Group C line from the discharge of the refueling water purification pump to the spent fuel pool is permanently installed.
This is the Category I water makeup circuit. The backup Safety Category I makeup system consists of piping and hoses from the Safety Category I fire protection system. The primary water makeup system non-Category I takes water from both primary water storage tanks and routes the water through the spent fuel pool water filter and then to the return header as indicated in Drawing M-63. In addition, primary water may be added to the spent fuel pool via a fire hose connection in the fuel handling building.
In summary, there are three sources of makeup water available, a primary unborated non-Category I source, a borated Safety Category I source, and an unborated fire protection Safety Category I water system. (Ref. 4, 5, and 6)The spent fuel pool system piping arrangement precludes siphoning after any failure by containing a 1/2-inch diameter hole four inches below the water level. Ten feet above the active fuel corresponds to an elevation of 410'-0". Both the cooling and skimmer systems meet this requirement.
No piping in the pool extends below the 410'-0" elevation except the spent fuel pool cooling system discharge pipe. This pipe contains an anti-siphon hole near the surface of the spent fuel pool. Therefore, piping connections to the SPF explicitly contain anti-siphon features which preclude a rapid drain down of the SFP.Excerpts from the Byron UFSAR Section 9.1.3-3 Safety Evaluation discuss SFP Dewatering incidents.
Incident C discussed is a sluice/transfer gate failure with the transfer canal empty, an open/empty transfer tube and an empty refueling cavity. In this incident, the spent fuel pool water level would be lowered approximately 22 feet 10 inches to the bottom sill of the sluice/transfer gate. This leaves at least 2 feet 6 inches of water as shielding over the active portion of the spent fuel in storage.4-5 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 This incident is not considered a rapid drain down transient.
The gate is a structural element, seismically designed as part of the SFP structural analysis, and is a passive barrier with no active components.
There is no rapid drain down consideration included in the Byron Unit 1 SWEL 2 list.4-6 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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 weeks of August 6 and August 20, 2012 and on September 19 and 22, 2012. It is noted that during the walkdowns the SWEs were generally accompanied by Operations and Engineering staff. The Seismic Walkdowns and Area Walk-Bys are discussed in more detail in the following 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 1 and SWEL 2 as provided in Appendix B of this report. 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 127 of the 127 items identified on the Byron Unit 1 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.It is noted that Question 6 on the SWCs is answered Y (yes) for all components unless a specific anchorage issue is identified.
This is pointed out because for certain 5-1 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 components Question 6 does not apply. However, the checkbox N/A (not applicable) is not provided as an option to address Question 6.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." 5.2.2 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* Corrosion that is more than mild surface oxidation* 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 CAP as a potentially adverse seismic condition.
5.2.3 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.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:
5-2 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161" 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.

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 as follows:* Proximity* Failure and falling of SSCs (Seismic II over I)" Flexibility of attached lines and cables Detailed guidance for evaluating each of these types of seismic spatial interactions is described in the EPRI guidance document, Appendix D: Seismic Spatial Interaction.
5-3 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-1 2-161 The Seismic Walkdown Engineers exercised their judgment to identify seismic interaction hazards. Section 5.2.6 provides a summary of issues identified during the Seismic Walkdowns.
5.2.5 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.
5.2.6 Conditions
Identified during Seismic Walkdowns Table 5-2 provides a summary of conditions identified during the equipment Seismic Walkdowns.
The equipment Seismic Walkdowns resulted in a total of eleven (11)conditions identified and each of these was entered into the station's CAP. All of the identified conditions 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.
The bases of the panels located in the Auxiliary Electric Equipment Rooms (AEER) are covered by a plastic cove molding. This molding prevents the visual inspection of the base weld anchorage detail for each panel. These panels were included on the SWEL because they were identified as IPEEE enhancements in that the panels were not connected together and in a seismic event could result in contact between the panels.The panels are also important components for functionality in a seismic event. The inspections by the SWEs did verify that the cabinets have been bolted to adjacent panels in response to the IPEEE enhancements.
The welds at the base can be seen through the molding as "bumps" in the material at most locations.
It is assumed that these are the connection welds since the spacing of the bumps closely approximates the detail as specified on Drawing 6E-0-3391C Revision BE. The seismic walkdown team could not determine if there were any cracks in the welds however the panels are non-vibratory and therefore, cracking of the welds is unlikely.
The seismic walkdown team could not determine if there was any corrosion of the weld however the AEER is a very dry environment so corrosion is unlikely.
Note that for 2 cabinets, the welds at the front of the panel could be visually inspected since the molding was not present due to a panel ventilation grate. The welds for these 2 cabinets met the drawing requirements with no corrosion and no cracking.
Based on these observations, it is adjudged acceptable to not remove the cove molding to perform an inspection of the anchorage 5-4 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 detail. The panels impacted are: 1PA01J -1PA12J, 1PA14J, 1PA28J, 1PA33J, 1PA34J, 1PA51J, and 1PA52J.There are instances in which small/hairline cracks in concrete have been identified on the SWCs as a note and/or with a photograph.
These small/hairline cracks are not of structural/seismic consequence due to their small size.5.3 AREA WALK-BYS The purpose of the Area Walk-Bys 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 51 A'rea Walk-bys were performed for Byron Unit 1.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* 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 T&RM MA-BY-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.Inspections of masonry walls were performed during the Area Walk-Bys.
Masonry walls were identified as seismic either by their placards and/or construction details such as block wall columns. Based on the IPEEE SER, all block walls in seismic areas are built to seismic standards. (Ref. 7)5-5 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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.
5.3.1 Seismically-Induced Flooding/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 piping" Flexible headers with stiffly supported branch lines* Non-Seismic Category I tanks The SWEs exercised their judgment to identify only those seismically-induced interactions that could lead to flooding or spray.5.3.2 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:
- Hazardous/flammable material stored in inadequately anchored drums, inadequately anchored shelves, or unlocked cabinets* 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 5-6 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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.5.3.3 Conditions Identified during Area Walk-bys Table 5-3 at the end of this section provides a summary of the conditions identified during the Area Walk-Bys.
Thirteen (13) conditions 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.Through the efforts of the seismic walkdowns and development of this report, IR 1431416 was initiated to share lessons learned with various workgroups across the station. In particular, the IR was issued to create an action to tailgate lessons learned with Electrical Maintenance, Electrical Maintenance Work Planning, and the Maintenance Contractor.
The focal point of the lessons learned is in regards to open fluorescent light fixture S-hooks. The expected S-hook configuration is that they are closed sufficiently to prevent the support chain links from passing though the S-hook up to metal-to-metal contact.It is noted that open fluorescent light fixture S-hooks identified during the Area Walk-Bys were deemed acceptable because they were found only slightly or partially open. In the configuration they were found, it is unlikely that the chain and S-hook could become disengaged.
5.4 SUPPLEMENTAL
INFORMATION ON ELECTRICAL CABINET INTERNAL INSPECTIONS 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.
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: 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 5-7 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 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 number (IR number).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.

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 CAP. In lieu of this process, Exelon/Byron utilized the existing processes and procedures (Site CAP Expectations) to identify, evaluate and document conditions identified during the Seismic Walkdowns.
In accordance with Exelon/Byron 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 CAP 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. For those conditions that required, seismic licensing basis evaluations were completed and documented within the IR. Tables 5-2 and 5-3 in the report provide the IR, a summary of the condition, and the action completion status.6-1 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 7 IPEEE Vulnerabilities Resolution Report Per the Individual Plant Examination of External Events (IPEEE) Submittal Report and the Staff Evaluation Report of Individual Plant Examination of External Events (IPEEE)submittal of Byron Station, Units 1 and 2 dated May 30, 2001, an explicit definition of vulnerability was not provided and no vulnerabilities with respect to potential severe accidents related to external events were not identified in the IPEEE submittal. (Ref. 3 and 7) However, plant improvements were identified in Sections 3 and 7 of Reference 3.Table G-1 in Appendix G lists the plant improvements, the IPEEE proposed resolution, the actual resolution and resolution date. No open items exist as a result of the seismic portion of the IPEEE program.7-1 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 8 Peer Review 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.

Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings.
Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is anchorage configuration verification required (i.e., is the item one of the 50% Yes of SWEL items requiring such verification)?
- 2. Is the anchorage free of bent, broken, missing or loose hardware?
Yes 3. Is the anchorage free of corrosion that is more than mild surface oxidation?
Yes 4. Is the anchorage free of visible cracks in the concrete near the anchors? Yes 5. Is the anchorage configuration consistent with plant documentation? (Note: Yes This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)
Drawing M-1227 Sheet I Revision R 6. Based on the above anchorage evaluations, is the anchorage free of Yes potentially adverse seismic conditions?

OB SX Pp 2000 GALLON DIESEL OIL STORAGE TANK Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
Yes 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
Lights supported on S-hooks. See IR 1399104 for open S-hooks. Note that the S-hooks are partially open and it is unlikely that they would become disengaged in a seismic event. Also lights would not damage equipment if they fell.9. Do attached lines have adequate flexibility to avoid damage?Yes Yes 10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?Yes Other Adverse Conditions
- 11. Have you looked for and found no adverse seismic conditions that could Yes adversely affect the safety functions of the equipment?
Some leaking (not diesel fuel, appears to be water) on floor but not a structural/seismic issue.Comments Seismic walkdown team M. Delaney & P.

Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings.
Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is anchorage configuration verification required (i.e., is the item one of the 50% No of SWEL items requiring such verification)?
- 2. Is the anchorage free of bent, broken, missing or loose hardware?Not Applicable
- 3. Is the anchorage free of corrosion that is more than mild surface oxidation?
- 4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation? (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)
Not Applicable Not Applicable Not Applicable
- 6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
An anchorage verification/inspection is not required since the equipment is mounted in-line without direct anchorage to the civil structure Yes C-48 Byron Generating Station Unit 1 12Q0108.20-R-001 Rev. 1 Correspondence No.: RS-12-161 Sheet 2 of 3 Status: M N U Seismic Walkdown Checklist (SWC)Equipment ID No.: OVC08Y Equipment Class: (10) Air Handlers Equipment
