E-2 vii DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 Executive Summary The purpose of this report is to provide information as requested by the Nuclear Regulatory Commission (NRC) in a letter issued to all nuclear power station licensees as well as holders of construction permits in active or deferred status. On March 12, 2012, the NRC issued a letter to all power reactor licensees in accordance with Title 10 of the Code of Federal Regulations, Part 50, Section 50.54(f).

The 50.54(f) letter requests information to assure that certain of the NTTF recommendations are addressed by all U.S. nuclear power plants [Ref. 2]. In particular, this report addresses Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter.Following the accident at the Fukushima Daiichi nuclear power plant resulting from the Great Tohoku Earthquake and subsequent tsunami, the NRC established the Near Term Task Force (NTTF). The NTTF made a series of recommendations, some of which were to be acted upon"without unnecessary delay". The NRC issued the 50.54(f) letter dated March 12, 2012 that requires, in part, that all U.S. nuclear power plants perform Seismic Walkdowns to identify and address degraded, non-conforming, or unanalyzed plant conditions and verify that the current plant configuration is in conformance with its Seismic Licensing Basis. This report documents the Seismic Walkdowns performed at the D. C. Cook Nuclear Power Plant Unit 1 (DCCNP1)and Unit 2 (DCCNP2) in response 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 [Ref.2], Enclosure 3, Recommendation 2.3: Seismic. 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 [Ref. 1].American Electric Power / D. C. Cook Nuclear Power Plant (DCCNP) has committed to using this NRC-endorsed guidance as the basis for the performed walkdowns and this report [Ref.14].DCCNP used the EPRI Guidance recommendations with only one exception.

DCCNP is submitting a combined report for DCCNP1 and DCCNP2. This is because the units are almost identical, they are designed by the utility, have the same Nuclear Steam Supply System (NSSS)supplier, the Auxiliary Building and Turbine Building/Screen house are common Unit 1 and 2 structures, and the equipment for the same purpose in both units are purchased from the same manufacturer and have the same Seismic Licensing Basis. There are Unit 1 equipment items in Unit 2 portions of the building and open areas and rooms include equipment for both units.Therefore there are some cross unit Area Walk-Bys performed due to equipment that was on the other unit's equipment list. Also, submitting a combined report is consistent with the IPEEE report [Ref. 18] submitted for the plant.In addition, DCCNP staff performed the licensing basis evaluations within the plants Corrective Action Program (CAP) process. All questionable conditions identified by the SWEs during the equipment Seismic Walkdowns or Area Walk-Bys were entered into the station CAP to be further evaluated and addressed as required.

The approach used for the DCCNP effort regarding potentially degraded conditions was conservative (in the context of Figure 1-3 of the Reference 1 EPRI Guidance).

Figure 1-3 of the EPRI Guidance allowed the plants to first viii DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 evaluate the potential condition without using the plant CAP process. If this interim evaluation indicated the equipment item or condition was within the Seismic Licensing Basis, it did not have to be evaluated using the CAP process. DCCNP took the approach to place the A equipment item or condition into the CAP process and evaluate the condition using that process that include licensing basis evaluations.

EPRI Technical Report 1025286 was used to perform the engineering walkdowns and evaluations described in this report. In accordance with EPRI Technical Report 1025286, the following topics are addressed in the subsequent sections of this report.* Seismic Licensing Basis* Personnel Qualifications

• Selection of Systems, Structures, and Components (SSCs)* Seismic Walkdowns and Area Walk-Bys* Seismic Licensing Basis Evaluations" IPEEE Vulnerabilities Resolution Report* Peer Review Revision 1 of this report includes the results of the initial online Seismic Walkdowns for DCCNP1 and DCCNP2 which were performed during the weeks of September 10, 2012 and September 17, 2012 when both units were operating.

In addition this report includes the results of the DCCNP1 outage walkdowns performed during the weeks of March 25, 2013 and April 1, A 2013. The revision also includes corrections/clarifications to the revision 0 report as a result of a self-assessment and discussions/communications with the USNRC during an audit of the walkdown process and report during the week of July 15, 2013.Seismic Licensing Basis The Seismic Licensing Basis for DCCNP1 and DCCNP2 is briefly described in Section 2 of this report. Detailed information regarding site seismology and seismic design of systems, structures, and components (SSCs) is discussed in the UFSAR [Ref. 3].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 EPRI Technical Report 1025286 [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 ix DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 Selection of SSCs The selection of SSCs is discussed in Section 4 of this report. The process used to select the equipment included in the overall Seismic Walkdown Equipment List (SWEL) is described in detail in EPRI Technical Report 1025286, Section 3: Selection of SSCs [Ref. 1]. Generally, the overall SWEL is divided into two groups of items as described in the following subsections.

Sample of Required Items for the Five Safety Functions

-SWELl Screen #1 narrowed the scope of SSCs in the plant to those that are designed to Seismic A Category I requirements because these SSCs have a Seismic Licensing Basis. I Screen #2 further reduced 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 documentation.

Cable/conduit raceways and HVAC ductwork, although not included as "equipment" in the SWEL, were reviewed during Area Walk- Bys in the vicinity of A equipment on the SWEL (in the same room or within 35').Screen #3 narrowed the scope of SSCs included on SWELl 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 is intended to result in a SWELl that sufficiently represented the broader population of plant equipment and systems needed to meet the objectives of the 50.54(f) letter [Ref. 2].The following five sample attributes are considered:

• A variety of types of systems* Major new or replacement equipment* A variety of types of equipment* A variety of environments

• Equipment enhanced due to vulnerabilities identified during the IPEEE program Spent Fuel Pool Related Items -SWEL2 Screen #1 and Screen #2 were used to narrow the scope of SSCs to those that have a Seismic A Licensing Basis and those that are appropriate for an equipment walkdown process.Screen #3 was a process intended to result in SWEL2 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 [Ref. 2], 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 x

DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 Screen #4 identified items of the spent fuel pool that could potentially cause a rapid drain-down of the pool, even if such items were not Seismic Category I. Any items identified as having the potential for rapidly draining the spent fuel pool were to be added to SWEL2.For DCCNP1 and DCCNP2, the overall SWEL is comprised of:* SWELl, DCCNP1 which resulted in 100 walkdown items.* SWEL2, DCCNP1 which resulted in 1 walkdown items." SWELl, DCCNP2 which resulted in 100 walkdown items.* SWEL2, DCCNP2 which resulted in 1 walkdown items." There are no SSCs associated with rapid drain down to be included on SWEL2.Seismic Walkdowns and Area Walk-Bys Section 5 of this report documents the equipment Seismic Walkdowns and the Area Walk-Bys.The initial online Seismic Walkdowns for DCCNP1 and DCCNP2 were performed during the weeks of September 10, 2012 and September 17, 2012 when both units were operating.

In addition, this Revision 1 report includes the Seismic Walkdowns and Area Walk-Bys performed for the remaining DCCNP1 equipment and areas on the SWEL that could only be accessed during the Unit 1 Outage in Spring 2013 that were completed during the weeks of March 25, 2013 and April 1, 2013.During the online walkdown activities, the walkdown team consisted of two Seismic Walkdown Engineers (SWE), and a plant Operator, who holds an active SRO license. Plant Design Engineering personnel also participated in the walkdowns.

Other Operations/Maintenance personnel were also available and called upon as needed.The Seismic Walkdowns focused primarily on the seismic adequacy of the SWEL items and on identifying:

• Adverse anchorage conditions

• Adverse seismic spatial interactions

• Other adverse seismic conditions (e.g., degradation)

Area Walk-Bys were conducted in each area of the plant that contained an item on the SWEL.The purpose of an Area Walk-by is to identify potentially adverse seismic conditions associated with other SSCs located within the vicinity of a SWEL item. There were 39 and 41 Area Walk-Bys completed for DCCNP1 and DCCNP2 respectively during the September 2012 online walkdowns.

The remaining Area Walk-Bys for Unit 1 were completed concurrent with the Unit 1 Outage A Walkdowns in Spring 2013.Area Walk-Bys for areas of Unit 2 that contain deferred equipment items will be defined during the Unit 2 Outage in Fall 2013. This will include areas inside the Containment Shield Wall and in two locked high radiation areas not accessible during the online walkdowns.

Xl DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 The key examination factors considered in the Area Walk-Bys included:* Anchorage conditions (if visible without opening equipment)

• Significantly degraded equipment in the area* Potential seismic interactions

• 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 interactions that could cause flooding/spray and fire in the area* Miscellaneous other conditions including conformance of temporary installations to general seismic housekeeping procedures During the online walkdowns, the seismic walkdown team inspected 84 of the 100 components on the SWELl for DCCNP1. The remaining 16 components on the SWELl for DCCNP1 were completed during the Unit 1 Outage in Spring 2013.During the online walkdowns, the seismic walkdown team inspected 84 of the 100 components on the SWELl for DCCNP2. There are 16 items that continue to be deferred for DCCNP2. Six of these items were located in Containment for DCCNP2 inside the Shield Wall and could not be included in the walkdown when the units were at power. There were nine electrical equipment items that could not be opened in DCCNP2 during the online walkdowns due to safety reasons.The remaining one item is in the Auxiliary Building, inside an enclosure and also could not be opened for safety reasons. The electrical equipment items will be inspected at the next service outage for those components.

The items in Containment and the item in the enclosure in the Auxiliary Building will be inspected during the Unit 2 Outage in Fall 2013. There are also Area Walk-Bys associated with the items in Containment that will be defined during the DCCNP2 outage walkdowns.

It is noted that all accessible areas of the plant included Area Walk-Bys including the rooms containing inaccessible electrical equipment.

Each unit had one SWEL2 equipment item that was completed during the online walkdowns.

Anchorage verifications for DCCNP1 and DCCNP2 were required for a minimum of 38 components each to meet the 50% verification requirements of EPRI Technical Report 1025286[Ref. 1]. The minimum required anchorage verifications reflect the elimination of in-line valves and temperature sensors on the SWEL that do not have anchorage and therefore are not subject to verification.

The components selected for anchorage verification numbered 46 and 45 for DCCNP1 and DCCNP2 respectively exceeding this minimum requirement.

A total of 40 and 38 anchorage configurations each for DCCNP1 and DCCNP2 respectively had anchorage verifications included in the online walkdowns.

During the online walkdowns, the anchorage configurations were either verified to be installed in accordance with DCCNP documentation or if found not to be in accordance, they were entered into the DCCNP CAP process. The remaining six anchorage verifications for DCCNP1 were confirmed during the outage walkdowns.

There are seven anchorage verifications that remain deferred for DCCNP2. There were no component anchorage non-conformances discovered that could potentially challenge the licensing basis of the plant.The anomalies or issues identified were minor and would not prevent the equipment from performing their safety-related functions.

These anomalies or issues were entered into the xii DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 DCCNP CAP process and were reconciled using that process which included a licensing basis evaluations for the condition.

There were no issues or conditions identified that could potentially challenge the licensing basis of the plant.A combined 23 Action Requests (ARs) were issued during the online walkdowns for both DCCNP1 and DCCNP2 to address conditions such as minor surface rust, housekeeping issues, A anchorage documentation anomalies and potential seismic interaction issues. There were 5 ARs issued for the DCCNP1 outage walkdowns that were of the same category.

The seismic issues were dispositioned in the Seismic Walkdown Checklists (SWCs) and Area Walk-By Checklists (AWCs) included in this report or using the DCCNP CAP process.Furthermore, as described in the discussion of seismic licensing basis evaluations, these conditions and other non-seismic issues were entered into the station's Corrective Action Program (CAP) to be addressed.

No planned or newly identified protection or mitigation features have resulted from the efforts to address the 50.54(f) letter.SWCs and AWCs were completed for all components and areas that were walked down. SWCs for deferred items and their associated AWCs will be completed at the time of the follow up walkdowns and a supplement to this submittal report will be issued. Any SWCs or AWCs that A need to be revised as a result of the deferred inspections will be updated in the submittal report.Seismic Licensing Basis Evaluations EPRI Technical Report 1025286, Section 5 [Ref. 1]: Seismic Licensing Basis Evaluation provides a detailed process to perform and document seismic licensing basis evaluations of SSCs when potentially adverse seismic conditions are identified during the equipment Seismic Walkdowns or Area Walk-Bys.

The process provides a means to identify, evaluate and document how the identified potentially adverse seismic condition meets a station's Seismic Licensing Basis, as shown in Figure 1-3 of the EPRI Guidance, without entering the condition into a station's Corrective Action Program (CAP). If this interim evaluation indicated the equipment item or condition was within the Seismic Licensing Basis, it did not have to be evaluated using the CAP process. The process directs that if a condition cannot be readily shown to meet the Seismic Licensing Basis, then the identified condition should be entered into the station's CAP where it will be determined if the condition does or does not meet the Seismic Licensing Basis.The approach used for the DCCNP effort regarding potentially degraded conditions was conservative (in the context of Figure 1-3 of the Reference 1 EPRI Guidance).

DCCNP entered any condition or potential condition into the CAP process and evaluated the condition using that process which includes the licensing basis evaluations.

All questionable conditions identified by the SWEs during the equipment Seismic Walkdowns or Area Walk-Bys were entered into the station CAP to be further evaluated and addressed as required.

Therefore, all seismic Licensing basis evaluations were completed in accordance with the DCCNP CAP process. A Tables 5-1 through 5-4 of Section 5 of this report provide a summary of the conditions identified during the online Seismic Walkdowns and Area Walk-Bys.Tables 5-5 and 5-6 of Section 5 of this report provide a summary of the conditions identified during the Seismic Walkdowns and Area Walk-Bys during the DCCNP1 Unit 1 Outage walkdowns.

1.1 BACKGROUND

In response to Near-Term Task Force (NTTF) Recommendation 2.3, the Nuclear Regulatory Commission (NRC) issued a 10CFR50.54(f) letter on March 12, 2012, [Ref. 2], requesting that all licensees perform Seismic Walkdowns to identify and address plant degraded, non- -conforming, or unanalyzed conditions, with respect to their current seismic licensing basis. TheL Nuclear Energy Institute (NEI), through the Electric Power Research Institute (EPRI), prepared industry guidance to assist licensees in responding to this NRC request. The industry guidance document, EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012 [Ref. 1], was endorsed by the NRC on May 31, 2012. American Electric Power and the DCCNP has committed to using this NRC-endorsed guidance as the basis for these walkdowns and this report [Ref. 14].1.2 PLANT OVERVIEW The DCCNP consists of two operating Pressurized Water Reactor (PWR) generating units, and is situated on the eastern shore of Lake Michigan, in Lake Township, Berrien County, Michigan, approximately 11 miles south-southwest of the city of Benton Harbor, MI. D. C. Cook Nuclear A Plant Unit 1 (DCCNP1) and D. C. Cook Nuclear Plant 2 (DCCNP2) each have a Westinghouse Ice Condenser containment with a plant-rated core thermal power level of 3,304 MWt and 3,468 MWt for Unit 1 and 2 respectively. (OPERATING LICENSE NO(s). DPR-58 & DPR-74 for Unit 1& 2 respectively).

DCCNP1 commenced commercial operation in 1974 [Ref. 15], and DCCNP2 commenced commercial operation in 1977 [Ref. 16].1.3 APPROACH The EPRI Seismic Walkdown Guidance [Ref. 1] was used for the DCCNP1 and DCCNP2 Seismic Walkdowns and evaluations described in this report. In accordance with [Ref. 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 Revision 1 of this report includes the results of the initial online Walkdowns for DCCNP1 and DCCNP2 which were performed during the weeks of September 10, 2012 and September 17, 2012 when both units were operating.

In addition this report to include the results of the A DCCNP1 outage walkdowns performed during the weeks of March 25, 2013 and April 1, 2013.The revision also includes corrections/clarifications from the Revision 0 submittal of this report in 1-1 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 November of 2012 as a result of a self assessment of the report submittal and discussions

/ A communications with the USNRC during an audit of the walkdowns and report during the week of July 15, 2013.1-2 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 2 Seismic Licensing Basis 2.1 OVERVIEW This section of the report summarizes the seismic licensing basis for both DCCNP1 and DCCNP2. The Design Basis earthquake and a summary of the codes, standards, and methods used in the design of Seismic Category I SSCs are presented.

DCCNP1 and DCCNP2 are almost identical, they are designed by the utility, have the same Nuclear Steam Supply System /.(NSSS) supplier, the Auxiliary Building and Turbine Building/Screenhouse are common Unit 1 and 2 structures, and the equipment for the same purpose in both units are purchased from the same manufacturer and have the same Seismic Licensing Basis.2.2 SEISMIC DESIGN The seismic licensing basis is defined in Sections 2.5 and 2.9 of the DCCNP UFSAR [Ref. 3].The seismology is defined in Section 2.5 and the seismic design criteria in Section 2.9 of Reference

3. Seismic design for the Containment Building is described in Section 5 of Reference 3.Design Response Spectra The seismic design response spectra (RS) were developed using the average Housner shaped ground response spectrum from [Ref. 5] normalized to 0.1Og for the Operating Basis Earthquake (OBE) and to 0.20g for the Design Basis Earthquake (DBE)/Safe Shutdown Earthquake (SSE).For the main structures, the vertical design response spectral values are taken as 2/3 the horizontal design response spectral values for the base level of the structure.

In-structure response spectra for Seismic Category I structures (referred to as Seismic ClassI A structures in the DCCNP UFSAR) were generated using time-history input from real A earthquakes which compositely envelope the horizontal seismic ground response spectra.Damping Values for Seismic Analysis Seismic analysis is performed using uniform system damping as a percent of critical damping.Damping values for use in seismic analysis of structures and equipment are presented in Table 2-1.2-1 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 Table 2-1 Damping Values Used for the Design of DCCNP1 and DCCNP2 (Ref. 3)1 Percent of Critical Damping Type of Structure Operating Basis Design Basis Earthquake Earthquake Containment Structure and all internal concrete 4%1 , 2%(21 7%('), 5%(z)structures Other conventionally reinforced concrete structures 2% 5%above grade, such as shear walls or rigid frames Welded structural steel assemblies 1% 1%Bolted or riveted steel assemblies 2% 2%Piping 0.5% 0.5%Notes: 1) Damping to be used for earthquake loads in combination with Design Accident Loads.2) Damping to be used for earthquake loads for load combination not including Design Accident Loads.Support Media for Category I Structures The DCCNP site foundation media is a simple sequence of geological formations consisting of a surface stratum of dune sand underlain by dense beach sands, a stiff clay stratum, and glacial till on shale bedrock. Major Category I structures are founded on mat foundations installed on the overlying compact sand, re-compacted sand, or stiff clay deposits.The top of bedrock is encountered at an elevation of about 100 feet below the bottom of the basemats for Category I structures.

Dynamic effects of the soil layers were appropriately considered.

Effects of Parameter Variations on Floor Response Spectra The effects on the calculated value of fundamental structural frequencies due to variations in soil shear moduli and concrete elasticity properties were taken into account for the Reactor Building by varying each +/-10%. To allow for soil and structure properties variations, the peaks on the response spectra curve were widened to include frequencies within +/-10% of the resonant frequency.

For the Auxiliary Building, response spectra were generated using a time history input developed from four real earthquake records, scaled and averaged to envelope the ground response spectra. Effective peak broadening of floor response spectra for the Auxiliary Building are on the order of +/-20% to +/-25%.Design Criteria for Seismic Category I Structures and Equipment All equipment and structures are classified as Class I, Class II, or Class III in accordance with Reference 3.Class I structures and components are those whose failure might cause or increase the severity of a loss-of-coolant accident or result in an uncontrolled release of excessive amounts of 2-2 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 radioactivity, and also, those structures and component vital to safe shutdown and isolation of the reactor.Class II structures and components are those which are important to reactor operation, but not essential to safe shutdown or isolation of the reactor, and whose failure would not result in the release of substantial amounts of radioactivity.

Class III structure and components are those which are not related to reactor operation or to containment.

Electrical and Mechanical Components and Supports Seismic Class I electrical and mechanical components and their supports are designed for seismic loads as described in UFSAR Section 2.9.6, [Ref. 3].In general, Class I equipment was designed for earthquake loads represented by combination of the appropriate horizontal and vertical floor responses applied simultaneously.

Vertical response was equal to 2/3 the horizontal response.Depending on the relative structural complexity and relative rigidity of the equipment evaluated, seismic qualification was performed using a dynamic multi-degree-of-freedom modal analysis, a dynamic single degree-of-freedom analysis considering the fundamental frequency of the equipment, a simplified dynamic analysis using the peak of the floor response spectrum, or by testing. The spent fuel racks were analyzed using time history analysis methodology.

Mechanical and Electrical equipment for two safe shutdown trains were evaluated during the Unresolved Safety Issue (USI) A-46 program, "Seismic Qualification of Equipment in Operating Plants". In this program the RS for DCCNP1 and DCCNP2 were deemed as median-centered spectra. Therefore, the anchorages for equipment located below 40' above grade and with fundamental frequencies above 8 Hz. were analyzed using the 5% critically damped ground spectra times a factor of 2.25 or the in-structure RS times a factor of 1.5. Anchorages for equipment located above 40' above grade or with fundamental frequencies below about 8 Hz.were analyzed using the 5% damped in-structure RS times a factor of 1.5. Flat bottom tanks were analyzed similarly except that the 3% damped spectra were used for the analysis.

Three directions of earthquake were combined by the square-root-sum-of-the-squares (SRSS)method.As discussed in Section 2.9.6.1 for the UFSAR [Ref. 3], use of earthquake experience data can be used as an alternative method for re-analysis or modification of existing items and to new or replacement items. This alternative method, however, in general, does not supersede specific commitments made for the seismic qualification of R.G. 1.97 [Ref. 6] equipment that is in general qualified using IEEE 344-1975 [Ref. 7].Piping Seismic Class I piping of 21/2 inch or greater and seismic Class I piping of less than 21/2 inch with operating temperature in excess of 250°F were dynamically analyzed for seismic loads. Vertical in-structure response spectra were taken equal to 2/3 the horizontal response spectra at the base of the pertinent building.

Analyses combined each horizontal response spectrum results with the vertical response spectrum results by SRSS, with the greater results of these two analyses at each node taken to be the critical load or stress.2-3 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 Seismic Class I piping smaller than 21/2 inch with operating temperatures less than 250°F were analyzed by either an alternate (support spacing) methodology or by computer dynamic analysis.Seismic Class I piping was analyzed for both OBE and DBE input.Seismic Class II piping with operating temperatures greater than 2501F were qualified by computer dynamic analysis, where seismic Class II piping with operating temperatures less than 250°F could be qualified by the alternate method. Seismic Class II piping used OBE response spectra for input.Applicable Codes Table 2-2 includes a summary of the Design Codes used in the DCCNP1 and DCCNP2 design.Table 2-2 DCCNP1 and DCCNP2 Summary of Design Codes SSC I Activity Design Code Reinforced concrete primary American Concrete Institute, Building Code containment Requirements for Reinforced Concrete ACI-318-63 and ACI-301-66.

3-5 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 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).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 [Ref. 1] was utilized to develop the SWEL list for DCCNP1 and DCCNP2.The SWEL is comprised of two groups of items: " SWELl is a sample of items to safely shut down the reactor and maintain containment integrity" SWEL2 is a list of spent fuel pool related items The results of the SWEL development are provided in the following tables: " Table B-1, DCCNP1 Base List 1 (Contained in Appendix B)" Table B-2, DCCNP2 Base List 1(Contained in Appendix B)* Table B-3, DCCNP Unit 1 and Unit 2 Common Base List 1 (Contained in Appendix B)" Table B-4, DCCNP1 SWELl, (Contained in Appendix B)" Table B-5: DCCNP1 SWEL2, (Contained in Appendix B)" Table B-6, DCCNP2 SWELl, (Contained in Appendix B)" Table B-7: DCCNP2 SWEL2, (Contained in Appendix B)" Table B-8, DCCNP1 Base List 2 (Contained in Appendix B)" Table B-9, DCCNP2 Base List 2 (Contained in Appendix B)The Base List i's contained in Tables B-i, B-2, and B-3 are the equipment coming out of Screen #3 and entering Screen #4 (the screens are discussed below) in Figure 1-1 of the EPRI Reference 1 Guidance.

It is noted that the Common Base List 1 are components that may be used for either DCCNP1 or DCCNP2 that come out of Screen #3. The Base List 2's contained in Tables B-8 and B-9 are the equipment coming out of Screen #2 and entering Screen #3 (the screens are discussed below) in Figure 1-2 of the EPRI Reference 1 Guidance.

Note that the Base List 2's for DCCNP are the same as the final SWEL 2 as there was only one component applicable to Spent Fuel Pool that was Seismic Category 1 equipment.

It is noted that Seismic Category 1 structures and components are referred to as Seismic Class I structures in the DCCNP UFSAR. The terminology "Seismic Category 1" is used in this discussion to be consistent with the EPRI [Ref. 1] guidance.The final SWEL selection is documented in the [Ref. 20] and [Ref. 21], Revision 1 reports. The SWELs contained in Tables B-4, B-5, B-6 and B-7 are identical to those documented in the [Ref.20] and [Ref. 21] reports. Minor changes to the component ID or descriptions that are included 4-1 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 in the walkdown sheets are included as notes to Tables B-4, B-5, B-6 and B-7 and are corrections that were discovered during this report revision process. These changes did not impact the physical items inspected.

The final SWEL revisions were made after the walkdowns were completed; however the components on the Revision 0 SWELs that were replaced in the Revision 1 SWELs were not included in the walkdown because of their inaccessibility.

They contained minor revisions to the SWEL selection in the Revision 0 versions of these reports due to ALARA and availability (having an electrical equipment outage that would allow an internal inspection).

The SWEL revisions were reviewed and approved by the same personnel approving the Revision 0 SWEL.Appendix B contains the signed covered pages for the Seismic Interim Reports [Ref. 20 and Ref. 21] providing the SWEL preparation, review and approval signatures as well as a description of the revisions.

The Revision 0 and Revision 1 SWELs were reviewed and approved by Mr. Brad Lewis that performed DCCNP Operations review as specified in the EPRI[Ref. 1] Guidance as indicated on the signed cover sheets.The changes to the DCCNP1 SWELl from Revision 0 to Revision 1 were as follows:* Item 9: Component changed from 1-AB-A-R2E to 1-AZ-BC-3B and component class from 2 to 1. 1-AZ-BC-3B was available for inspection during the recently completed DCCNP1 outage and 1-AB-A-R2E was not.* Item 10: Component changed from 1-EZC-A-RIA to 1-AZ-BC and component class from 2 to 1. 1-AZ-BC was available for inspection during the recently completed DCCNP1 outage and 1-EZC-A-R1A was not." Item 11: Component changed from 1-EZC-B-R5A to 1-11B with no change to /component class. 1-1 1B was available for inspection during the recently completed DCCNP1 outage and 1-EZC-B-R5A was not.* Item 69: Component changed from 1-BLP-112 to 1-BLP-132.

This was a change of an identical component from a different protection channel that was made for ALARA purposes.The changes to the DCCNP2 SWELl from Revision 0 to Revision 1 were as follows: " Item 6: Component changed from 2-21A9 to 2-21C with no change to component class. 2-21C was available for inspection during the next DCCNP2 outage and 2-21A9 was not." Item 9: Component changed from 2-21A5 to 2-21C6 with no change to component class. 2-21C6 was available for inspection during the next DCCNP2 outage and 2-21A5 was not.* Item 11: Component changed from 2-21 B1 to 2-21 C1 0 with no change to component class. 2-21C10 was available for inspection during the next DCCNP2 outage and 2-21B1 was not." Item 31: Component changed from 2-21A10 to 2-TR21A with no change to component class. 2-TR21A was available for inspection during the next DCCNP2 outage and 2-21A10 was not." Item 69: Component changed from 2-BLP-112 to 2-BLP-132.

This was a change of an identical component from a different protection channel that was made for ALARA purposes.4-2 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 All components included on the SWELs for DCCNP1 were completed between the online and DCCNP1 Unit 1 Outage walkdowns.

During the online walkdowns, the seismic walkdown team inspected 84 of the 100 components on the SWELl and the single SWEL2 component for DCCNP2. There are 16 items that continue to be deferred forDCCNP2 that are listed in Appendix E, Table E-1 of this report.4.2.1 SWELl -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 DCCNP Seismic-Walkdown-List-07-24-12-rev1

[Ref. 11]." Screen #1 -Seismic Category 1 As described in Reference 1, only items that have a defined Seismic Licensing Basis are to be included in SWELl. Each item on the DCCNP Seismic-Walkdown-List was reviewed to determine if it had a defined Seismic Licensing Basis. All items identified as Seismic Category I, as defined in DCCNP UFSAR Chapter 2 [Ref. 3], were determined to have a defined Seismic Licensing Basis." 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. Consistent with the EPRI Technical Report 1025286 [Ref. 1], this screen further reduced the DCCNP Seismic-Walkdown-List of any Safety Category I Structures, Containment Penetrations, Safety Category I Piping Systems, cable/conduit raceways and HVAC ductwork.As described in the DCCNP1 and DCCNP2 Technical Specification Bases [Ref. 12] and[Ref. 17] respectively, the ice condenser is a passive system that requires no electrical power to perform its function.

The ice condenser is an annular compartment enclosing approximately 3000 of the perimeter of the upper containment compartment, but penetrating the operating deck so that a portion extends into the lower containment compartment.

The lower portion has a series of hinged doors exposed to the atmosphere of the lower containment compartment, which, for normal unit operation, are designed to remain closed. At the top of the ice condenser is another set of doors exposed to the atmosphere of the upper compartment, which also remain closed during normal unit operation.

Intermediate deck doors, located below the top deck doors, form the floor of a plenum at the upper part of the ice condenser.

These doors also remain closed during normal unit operation.

The upper plenum area is used to facilitate surveillance and maintenance of the ice bed.In the event of a DBA, the ice condenser inlet doors (located below the operating deck)open due to the pressure rise in the lower compartment.

This allows air and steam to flow from the lower compartment into the ice condenser.

The resulting pressure increase within the ice condenser causes the intermediate deck doors and the top deck doors to open, which allows the air to flow out of the ice condenser into the upper compartment.

Steam condensation within the ice condenser limits the pressure and temperature buildup in containment.

A divider barrier (i.e., operating deck and extensions thereof) separates the upper and lower compartments and ensures that the steam is directed into the ice condenser.

These inspections include:* SR 3.6.11.5-Verification, by visual inspection of the ice baskets, for detrimental structural wear, cracks, corrosion, or other damage. This SR ensures that a representative sampling of ice baskets, which are relatively thin walled, perforated cylinders, have not been degraded by wear, cracks, corrosion, or other damage. The SR is designed around a full-length inspection of a sample of baskets, and is intended to monitor the effect of the ice condenser environment on ice baskets.* SR 3.6.12.2 -Verification, by visual inspection, that each intermediate deck door is closed and not impaired by ice, frost, or debris provides assurance that the intermediate deck doors (which form the floor of the upper plenum where frequent maintenance on the ice bed is performed) have not been left open or obstructed.

• SR 3.6.12.3 -Verification, by visual inspection, that the top deck doors are in place and not obstructed provides assurance that the doors are performing their function of keeping warm air out of the ice condenser during normal operation, and would not be obstructed if called upon to open in response to a DBA.* SR 3.6.12.4 -Verification, by visual inspection, that the ice condenser inlet doors are not impaired by ice, frost, or debris provides assurance that the doors are free to open in the event of a DBA." SR 3.6.12.5 -Verification of the opening torque of the inlet doors provides assurance that no doors have become stuck in the closed position.Based upon these Surveillance requirements, ice condenser SSCs regularly undergo inspections to confirm that their configuration is consistent with the plant Seismic Licensing Basis. Therefore, ice condenser SSCs are screened out of consideration for SWELl inclusion.

• Screen #3 -Support for the 5 Safety Functions This screen narrowed the scope of items included on the SWELl to only those associated with maintaining the following five safety functions: " Reactor Reactivity Control (RRC)" Reactor Coolant Pressure Control (RCPC)" Reactor Coolant Inventory Control (RCIC)" Decay Heat Removal (DHR)" 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 DCCNP Seismic-Walkdown-List

[Ref. 11], was identified.

It is noted that items on SWELl with a specific safety function(s) are considered frontline systems. Items with a safety function designation of 'Support System HVAC (SSHVAC)', 'Support System AC 4-4 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 Power' (SSAC), 'Support System DC Power' (SSDC), Engineered Safety Features Actuation System ('ESFAS'), 'Cooling Water (UHS)' or 'Compressed Air' (SSCA) may be a frontline or support system. Items with a Support System safety support at least one of the five safety functions.

Screen #4 -Sample Considerations This screen is intended to result in a SWELl 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 [Ref. 2]. The following attributes were consideration in the selection process for items included on SWELl:* A variety of types of systems The system is identified for each item on SWELl. The equipment included on SWELl 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 SWELl includes several items that have been modified or replaced.

Each item on SWELl that is new or replaced is identified.

• A variety of types of equipment The equipment class is identified for each item on SWELl. The equipment included on SWELl 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 SWELl.Screening

1. 1, #2, and #3 resulted in no equipment in Classes (11)Chillers and (13) Motor Generators.

There were no Class (11) Chillers included on the SWELl. As described in the Reference 1 Guidance, Screen #1 narrows the scope of SSCs in the plant to those that are classified as Seismic Category I. The assignment of equipment using Reference 1, Appendix B: Classes of Equipment, resulted in equipment in Class (10) Air Handlers and no equipment in Class (11) chillers.There are no Seismic Category I, Class (13) Motor Generators at DCCNP as the A plants are Westinghouse PWR Units and the only Motor Generators are associated with the Control Rod Drive Mechanisms (CRDMs) that are not Seismic Category I.This was an expected potential result of the SWELl development according to the Reference 1 Guidance which states on pg. 3-5; "not all plants have all the various types of equipment classes described in Appendix B: Classes of Equipment.

For example, some plants generate DC power using inverters and therefore do not have motor generators."* A variety of environments 4-5 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 The location for each item is identified on SWELl; including the Auxiliary Building, Containment, Turbine Building, and Screenhouse.

The equipment included on SWELl is a representative sample from a variety of environments (locations) in the station.* Equipment enhanced due to vulnerabilities identified during the IPEEE program The equipment included on SWELl includes several items that were enhanced as a result of the IPEEE program. Each item on SWEL that was enhanced to correct a vulnerability form IPEEE is identified.

• Contribution to risk In selecting items for SWELl 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 SWELl to confirm that a reasonable sample of risk-significant components (relevant for a seismic event) were included on SWELl.It is noted that the resulting SWELl includes a representative sample of equipment.

This result was obtained by following the requirements of the EPRI Guideline

[Ref. 1], which require selection of SSCs from multiple, systems, possessing different safety functions and twenty different Equipment Classes.4.2.2 SWEL2 -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 (SWEL2):* Screen #1 -Seismic Category 1 Only those items identified as Seismic Category 1(Safety Category I) are to be included on SWEL2 with exception to the SFP structure.

As described in Reference 3, the adequacy of the SFP structure is assessed by analysis as a Seismic Category 1 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 SWEL2.Each of the two cooling loops in the Spent Fuel Pool Cooling System consists of a pump, heat exchanger, strainer, piping, associated valves and instrumentation.

The pump draws water from the pool, circulates it through the heat exchanger and returns it to the pool. Component cooling water cools the heat exchanger[References 3, 8, and 9]. All Spent Fuel Pit Cooling system components are Seismic Class II and III per References 3 and 8.DCCNP Drawing OP-1-5135B-23 shows the Seismic Class I Component Cooling system cools the SFP flow though the SFP Heat Exchanger.

With a connection 4-6 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 to the Seismic Class I Component Cooling Water system, there is a Seismic Licensing Basis for the Spent Fuel Pit Heat Exchangers.

Screen #2 -Equipment or Systems This screen considers only those items associated with the SFP that are appropriate for an equipment walkdown process. The SFP Weir Gates are not included in the SWEL list, as these items are considered structures.

Though identified as Seismic Class II, the SFP Heat Exchangers are the sole component on the DCCNP1 and DCCNP2 SWEL2 list.Screen #3 -Sample Considerations This screen represents a process that is intended to result in a SWEL2 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 [Ref. 2]. The following attributes were considered in the development of SWEL2: " A variety of types of systems All Spent Fuel Pit Cooling system components are Seismic Class II and III per References 3 and 8. Because of the connection to the Component Cooling System, only the Spent Fuel Pit cooling system is represented on the SWEL2 list." Major new and replacement equipment There are no identified modifications to the SFP heat exchanger." A variety of types of equipment The only equipment class represented is (21) Tanks and Heat Exchangers." A variety of environments The SFP Heat Exchanger is located in the Auxiliary Building.Screen #4 -Rapid Drain-Down This screen identifies items that could allow the spent fuel pool to drain rapidly.To protect against this possibility, the spent fuel pit cooling connections enter near the normal water level so that the pool cannot be gravity-drained.

Per Reference 8, suction connections for the SFP pumps are strainers at elevation 643'6" near the normal pit water level. The return piping has a 11/2-inch hole through the piping wall four (4) inches below the SF Pit waterline

[Ref. 8 and 10].Therefore, there are no rapid-drain-down concerns for DCCNP1 and DCCNP2.4-7 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 5 Seismic Walkdowns and Area Walk-Bys 5.1 OVERVIEW Seismic Walkdowns and Area Walk-Bys were conducted by two-person teams of trained Seismic Walkdown Engineers, in accordance with the EPRI Seismic Walkdown Guidance, [Ref.1]. The online walkdowns were completed during the weeks of September 10, 2012 and September 17, 2012. The remaining components and Area Walk-Bys for DCCNP1 were completed during the outage walkdowns during the weeks of March 25, 2013 and April 1, 2013.The Seismic Walkdowns and Area Walk-Bys are discussed in more detail in the following sections.5.2 SEISMIC WALKDOWNS The components included in the Seismic Walkdowns are shown on the DCCNP1 and DCCNP2 SWELl and SWEL2 in Appendix B. A Seismic Walkdown Checklist (SWC) from Appendix C of[Ref. 1] was completed for each item on the SWEL. SWCs for the deferred items identified except for those discussed below are not included in Appendix C. Partial walkdowns were performed on three and four electrical components in DCCNP1 and DCCNP2 respectively.

A These electrical components could not be opened for internal inspection due to safety concerns.These components are included in Tables C-1 and C-2 that document the equipment items included with the online walkdowns.

Seismic Walkdown Checklists are included for the three Unit 1 electrical components and they were walked down again during the DCCNP1 outage walkdowns.

They are again included in Table C-3 and new walkdown checklists are included with the outage walkdown component checklists.

The completed SWCs for the DCCNP2 deferred items will be added at a later date. (Deferred items are discussed in Appendix E.) Additionally, photos are included with most SWCs to provide a visual record of the walkdowns along with the walkdown observations.

Seismic Walkdowns are now complete for all 100DCCNP1 SWELl components.

Seismic Walkdowns were completed for 84 of the of the 100 on the DCCNP2 SWELl with 16 items being deferred including the four partially completed items that have partial checklists included with this report.The one SWEL2 component each for DCCNP1 and DCCNP2 is complete.Table E-1 in Attachment E includes the list deferred walkdown equipment items for DCCNP2.The deferred items are located in Containment inside the Shield Wall, are in high radiation areas of the Auxiliary Building or are electrical equipment items that, for safety reasons, could not be opened during the online walkdowns.

5.2.1 Anchorage Configuration Confirmation As required by [Ref. 1] (page 4-3), 50% of the items were confirmed to have anchorage configurations consistent with plant documentation.

The table of contents for Appendix C indicates the anchorage verification status for components as follows: 5-1 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 N/A: components that are line-mounted and/or are not anchored to the civil structure and therefore do not count in the anchorage confirmation total. It is noted that EPRI guidance document, Technical Report 1025286, [Ref. 1] includes Question 6 on the SWC's; "Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?" and only provides for a Yes, No or Unknown answer. The answer for question 6 is therefore given a "Yes" when the answers to questions 1 to 5 on the check list are "N/A".Y: components anchored to the civil structure which were confirmed to be consistent with plant configuration documentation N: components for which anchorage drawings were not designated for retrieval because they were not included in the 50% sample or they did not have specific anchorage associated with them because they were in-line equipment items.The approach taken was to have at least half of each equipment class where the anchorage was applicable (eliminated line-mounted items that are N/A from the population).

In general if there were an even number of items in an equipment class, half were included for anchorage configuration confirmation.

When there were an odd amount of items for a given class, the number of anchorage verifications to be conducted was rounded up. There were 76 and 75 equipment items in the combined SWELl and SWEL2 lists for DCCNP1 and DCCNP2 respectively that were in the population eligible for anchorage verification.

Of these, 46 and 45 were chosen to require anchorage verification for DCCNP1 and DCCNP2, respectively.

A total of 40 and 38 anchorage configurations each for DCCNP1 and DCCNP2 had anchorage verifications included in the online walkdown's.

During the online walkdowns they were confirmed to either be installed in accordance with DCCNP documentation or they were enteredA into the DCCNP CAP process. The remaining six anchorage verifications for DCCNP1 were confirmed during the outage walkdowns.

There are seven anchorage verifications that remain deferred for DCCNP2. There were no component anchorage non-conformances discovered that could potentially challenge the Seismic Licensing Basis of the plant.5.2.2 Issues Identification during Seismic Walkdowns The anomalies or issues identified by the SWEs during the equipment walkdowns were evaluated using the DCCNP CAP and determined not to be a condition that adversely impacted the Seismic Licensing Basis. Operability determinations of anomalies or issues identified on the walkdowns were completed by licensed operators and were done within the CAP. Table 5-1 A and Table 5-3 provide a summary of the issues identified in the Seismic Walkdowns for DCCNP1 and DCCNP2 respectively during the online walkdowns.

Table 5-5 provides the summary for the DCCNP1 outage walkdowns.

These were all for SWELl equipment items, there were none for items on the SWEL2. No planned or newly identified protection or mitigation feature changes to DCCNP1 or DCCNP2 have resulted from the Seismic Walkdown Process.5.3 AREA WALK-BYS In accordance with Reference 1, Area Walk-Bys were performed for each room or area within a large room (35 foot radius) which included one or more items on the SWEL. The table of contents in Appendix D (provides a description of the Area Walk-By. All completed Area Walk-By Checklists (AWCs) are included in Appendix D. Photos are included with the AWCs in A addition to the walkdown observations.

These include overhead areas and other equipment 5-2 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1,09/12/2013 items not on the SWELs in the area. A total of 39 and 41 AWCs were completed for Unit 1 and Unit 2 respectively for the online walkdowns.

A total of 7 AWCs were completed for the DCCNP1 outage walkdowns.

5.3.1 Issue Identification during Area Walk-Bys None of the anomalies or issues identified by the SWEs during the Area Walk-Bys was ultimately judged to be "Potentially Adverse Seismic Conditions" because in all cases it was concluded that the anomaly or issue would not prevent the equipment from performing its safety-related function during or after a seismic event. Table 5-2 and Table 5-4 provides a summary of the issues identified in the Area Walk-Bys for DCCNP1 and DCCNP2 respectively for the online Area Walk-Bys.

Table 5-6 provides the Area Walk-By summary for the DCCNP1 outage walkdowns.

Discrepancies and questionable conditions identified by the SWEs during the equipment Seismic Walkdowns or Area Walk-Bys were entered into the DCCNP CAP to be further evaluated and resolved.

The questionable conditions included physical conditions and documentation issues.The approach used for the effort regarding potentially degraded conditions was conservative (in the context of Figure 1-3 of the Reference 1 EPRI Guidance).

Figure 1-3 of the EPRI Guidance allowed potential conditions to be evaluated within the Seismic Walkdown process without using the CAP process. If this Seismic Walkdown process evaluation concluded the equipment item or condition was within the Seismic Licensing Basis, it did not have to be entered into the CAP process for further evaluation.

In accordance with the DCCNP processes and procedures, potential conditions identified during the Seismic Walkdown process were entered into the DCCNP CAP and the conditions were evaluated using the CAP that includes the licensing basis evaluations.

The resolutions of the conditions were also completed within the CAP.The conditions/issued identified during the Seismic Walkdown process included material condition items, physical configuration items, and documentation discrepancies.

The conditions/issues entered into the DCCNP CAP process are shown in Tables 5-1 through 5-6.The evaluations of the conditions have been completed.

The evaluations determined that there were no issues or conditions identified that could potentially challenge the Seismic Licensing Basis. Resolution of the issues included corrective maintenance, "Use-As-Is" acceptance, and documentation updates. The current status of individual item resolutions is shown in Tables 5-1 through 5-6. There are no planned or newly installed changes to the plant as a result of implementing the Seismic Walkdown process.6-1 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 7 IPEEE Vulnerabilities Resolution Report The Individual Plant Examination of External Events (IPEEE) seismic analyses for DCCNP1 and DCCNP2 were performed simultaneously.

A number of benefits were derived from the IPEEE.These benefits included an appreciation of the range of severe accidents that could occur at DCCNP1 and DCCNP2 from external hazards such as seismic hazards. The more likely sequences that contribute to risk, the importance of equipment, systems, and human actions that determine the risk were included in the analyses.In general, no DCCNP safety features (beyond features standard to Westinghouse PWRs) were noted in the IPEEE. The walkdowns performed in support of the IPEEE seismic analyses included both DCCNP1 and DCCNP2. The results of the IPEEE seismic analyses are documented in the IPEEE summary report [Ref. 18] and the response to the NRC staff Request for Additional Information (RAI) [Ref. 19]. Findings identified during the IPEEE including the resolutions are summarized in Table 7-1. Items identified during the IPEEE that were maintenance and housekeeping items are summarized in Table 7-2. Resolution of design issues identified during the IPEEE, are summarized in Table 7-3. The resolutions of these vulnerabilities were completed prior to the response to the NRC RAI dated February 15, 1995[Ref. 19].A sample of the equipment associated with the seismic IPEEE vulnerabilities was included in this Seismic Walkdown process. Tables 7-1 through 7-3 also provide a cross reference between the seismic IPEEE vulnerability and the Seismic Walkdown item or Area Walk-by. The Seismic Walkdown process did not identify a reoccurrence of the seismic IPEEE vulnerabilities.

This effort included the following activities: " A review of the selection of the structures, systems, and components, SSCs included on the Seismic Walkdown Equipment List, SWEL" A site visit by Peer Review Team Member, Mr. Todd Bacon on September 17, 2012 during the online walkdown who reviewed documentation and interviewed the JA Walkdown Team. It is noted that due to a stand down at the site, the Peer Reviewer was unable to accompany the Walkdown Team while performing the walkdowns." A review of a sample of the checklists completed for the Seismic Walkdowns and Area Walk-Bys" A review of any licensing basis evaluations" A review of the decisions for entering or not entering the potentially adverse seismic conditions into the CAP process" A review of the Revision 0 submittal report. In addition the Revision 1 submittal report was reviewed along the checklists from the DCCNP1 outage walkdowns." The inclusion of a summary of the peer review process in the submittal report The Peer Review Checklist is included in Appendix F. The Peer Review report is included in its entirety in this Section of the report. A The SWEL development was performed by Mr. Kim Hull of S&A. No findings were cited on the Peer Review Checklist.

The completed SWEL Peer Review Checklist is found in Attachment F of this report. The discussion for the SWEL development peer review is found in Section 8.2.The peer review of the Seismic Walkdown inspection started on September 17, 2012 with a peer check of the walkdown team. Mr. Bacon joined the walkdown team for a portion of the day to observe the adherence to the SWG and to review a portion of the checklists completed at that time. Interviews were also conducted by Misters Bacon and Djordjevic with the SWE inspection team after review of a sample of the Unit 1 Seismic Walkdown Checklists (SWCs) and the Area Walk-By Checklists (AWCs) to ascertain procedural compliance with the SWG. The interviews were conducted with Mr. Gary Thomas and Ms. Neda Stoeva of the SWE inspection team on October 12. The discussion of the sample SWCs and AWCs is provided in Section 8.3.No issues were identified which challenged the current licensing basis.8-1 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 8.2 PEER REVIEW -SELECTION OF SSCs 8.2.1 Purpose The purpose of this section is to describe the process to perform the peer review of the selected structures, systems, and components, (SSCs) that were included in the Seismic Walkdown Equipment List (SWEL).The peer review for the selection of SSCs was performed by Mr. T.

• Section 4 and Appendix B of this report This peer review was based on interviews with the following individual who was directly responsible for development of the SWEL:* Mr. Kim Hull, Senior Mechanical Engineer This peer review utilized the checklist shown in the SWG, Appendix F: Checklist for Peer Review of SSC Selection.

For SWELl development, the following actions were completed in the peer review process:* Verification that the SSCs selected represented a diverse sample of the equipment required to perform the following five safety functions:

o Reactor Reactivity Control (RRC)o Reactor Coolant Pressure Control (RCPC)o Reactor Coolant Inventory Control (RCIC)o Decay Heat Removal (DHR)" Containment Function (CF)This peer review determined that the SSCs selected for the Seismic Walkdowns represent a diverse sample of equipment required to perform the five safety functions." Verification that the SSCs selected include an appropriate representation of items having the following sample selection attributes:

o Various types of systems" Major new and replacement equipment 8-2 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 o Various types of equipment o Various environments o Equipment enhanced based on the findings of the IPEEE o Risk insight consideration This peer review determined that the SSCs selected for the Seismic Walkdowns include a sample of items that represent each attribute/consideration identified above.For SWEL2 development, the following actions were completed in the peer review process: " Verification that spent fuel pool related items were considered and appropriately added to SWEL2.This peer review determined that spent fuel pool related items were given appropriate consideration.

Portions of the spent fuel pool cooling system are classified as Seismic Category 1 (Class I) and SWEL2 was sufficiently populated as appropriate." Verification that appropriate justification was documented for spent fuel pool related items that were not added to the SWEL2.This peer review determined that an appropriate level of justification was documented for those items related to the spent fuel pool that were not added to SWEL2.8.2.3 Peer Review Findings -Selection of SSCs This peer review found that the process for selecting SSCs that were added to the SWEL was consistent with the process outlined in the Reference 1 Seismic Walkdown Guidelines, Section 3: Selection of SSCs.The peer review checklist is attached to this document.

The peer review resulted in no additional findings.8.2.4 Resolution of Peer Review Comments -Selection of SSCs All comments requiring resolution were incorporated prior to completion of this peer review.8.2.5 Conclusion of Peer Review -Selection of SSCs This peer review concludes that the process for selecting SSCs to be included on the Seismic Walkdown equipment list appropriately followed the process outlined in the SWG, Section 3: Selection of SSCs [Ref. 1]. It is further concluded that the SWEL sufficiently represents a broad population of plant Seismic Category 1 (Class I) equipment and systems to meet the objectives of the NRC 50.54(f) letter [Ref. 2].8-3 DC Cook Unit 1 & Unit 2 SD-121023-001 Rev. 1, 09/12/2013 8.3 REVIEW OF SAMPLE CHECKLIST
