SUMMARY

AND CONCLUSIONS- ,

This Resuhs Repon summarizes the results of a Third Pany review of the design adequacy of cable trays and cable tray supports (cable tray / supports) at the Comanche Peak Steam Electric Srarion (CPSES). This review was performed as a pan of the Design Adequacy Program (DAP) i under the chaner of the Comanche Peak Response Team (CPRT) Program Plan (R<f. 7.1.1] by a Third Pany Organization (TENERA, L.P.). The approach, methodology, and scope developed to accomplish this review are described as pan of the Civil / Structural Discipline Specific Action  ;

Plan (DSAP VIII), which is contained in Appendix C of the CPRT Program Plan, with additional modifications as defined in Revision 4 to the CPRT Program Plan, Appendix A.

DSAP M encompasses all of the Civil / Structural design review activities performed under the DAP, including both Project and Third Pany activities related to major conective action 1

programs and Third Pany self-initiated review activities. This Results Repon is limited to summarizing the Third Party review activities associated with the overview of the CPSES cable tray /suppons corrective action pegram.

• "In CPSES cable tray / supports program described in DSAP VIII consists of a 100% design validation effort performed by TU Electric contractors (Project) with an overview of these -

~

activities performed by the Third Pany. The contractors responsible for design validation are "

Ebasco Services lacorporated(Ebasco) and Inqpelt Corporation (Impell). These organizations share the scope of work for Unit I and Ebasco has full scope for Unit 2. The Third Pany as noted above is TENERA, L.P.

1he purpose of the DSAP W cable tray / supports program is to pmvide reasonable assurance that the cable tray / supports at the CPSES are adequately designed and that the design validadon effon resolves extemal source issues related to the original design by Gibbs and Hill. " Design Adequacy" is defined as conformance to the CPSES FinalSq(ety Analysis Report (FSAR) (Ref.

7.1.2) and licensing commitments,includmg appropriate codes and standards. The purpose of the Third Pany overview is to provide an element of this assurance thmugh overview of selected portions of the program. This Results Report documents the results and conclusions of the Third Pany overview defined in DSAP M (as modified in Revision 4 to the CPRT Program Plan) with respect to both the M7 of the cable tray /suppons design and the resolution of external source issues.

The scope of the1hird Party review activities that were performed is as follows:

• Isme Review (DSAP VIII, Section 4.1.2.1)

Calatsia/ Commitment Verification (DSAP M. Section 4.1.2.2)

• Cable tray /suppons design validation procedures and supporting documentation review (DSAP VIII, Section 4.1.2.3)

Briefly stated the review identified extemal source issues, established applicable criteria based on the CPSES FSAR and licensing commitments, compared both Ebasco's and Impell's procedures and supponing documentation with those criteria, and evaluated the resolution i

methodologies for the issues. Overview of the implementation of the procedures for cable

. ray /suppons, including verification of design input such as construction as built data, will be  ;

covered under the TU Electric QA Technical Audit Program. i TN-87 7259 11 DAP RR C/S-001, REV 1

n v

The identificatiorhof extemal source issues was accomplished by conducting a doc of over 40,000 pages of NRC docketed material. This effon resulted in the issuance of approximately 200 cable tray /suppons related Discrepancy //ssue Resolurion Reports (Dins) to i

documern and track concerns raised by extemal sources. The primary sources of cable l

tray / supports concems,were the results of the Independent Assessment Program (IAP) performed l

by Cygna Energy Services (Cygna). Most of the concems expressed by other external sources were similar to, or a reiteradon of, the concems expressed by Cygna. 'Ihese DIRs were consolidated into thiny-one (31) issue groups to facilitate resciution of the concems. Discussions of these issue smups are presented in Section 3.0 of this report. j

'Ihe assessment of the overall adequacy of Ebasco's and Impell's design validation effon was accomplished by'Ihird Party review of the procedures, supporting special studies and tests, and resolution methodology for each extemal source issue. These reviews were performed to evaluate the adequacy of Ebasco's and Impell's design validation procr4ures and to assess their compliance with applicable FSAR and licensing criteria. Based on the firviings of these reviews, it is concluded that the design validadon procedures and issue resolution methodologies are in conformance with the appropriate criteria.

In summary, the 'Ihird Party has concluded that the Project's cable tray / supports design

.~

validation program is comprehensive and capable of resolving known technical issues and -

assuring that the design will meet the FSAR and licensing commitments. '

O 3.0 EXTERNAL SOURCE ISSUES This section of the report describes the Third Party's activities performed in the overview of Project's resolution of extemal source issues. These activities, which relate to Sections 4 4.1.2.2, and 4.1.2.3 of DSAP Vill for cable tray / supports, include the following:

Extemal Source Issues Identification.

Design Criteria / Commitments Identification.

As Built Procedures Review, Design Validadon Procedures Review,

• Special Studies Review,

• Test Programs Review, and a

Issue Resolution Review.

These activities were performed to assess the overall adequacy of the Project's design validati methodology and approach for resolution of specific extemal source issues.

i The conduct of the Third Party overview activities was in acconiance with DAP procedures (Reference 7.5.92). These procedures control the developrnent of criteria lists and checidis implementation of checklists, preparation of engineering evaluation repons, and the identification, documentadon, and resolution ofissues. Figure 3.1 1 is a flow chan of the overview acdvities performed by the Third Pany.

Section 3.1 describes the review methods and Section 3.2 provides the results for each of the overview activities. For each of the extemal source issues, Section 3.2.7 contams a discussion of the issue, the Project's resolution methodology and the results of the Third Pany's evaluation.

3.1 Review Methodology The Third Pany review methodology for the activities noted above is described separately for each activity in the following subsections.

3.1.1 Extemal Source issues identification Extemal source lasues were identified and documented in the following three steps:

1) idensincation of extemal source documents,

2) source document review and preparation ofissue records /DIRs, and

3) consolidadon of individual issues into issue groups.

The initial identification of source documents focused on documents judged to include summaries of relevant issues, panicularly information either presented to the Atomic and Sq(cry Licensin Board (ASLB) or originated by the ASLB. ASLB hearing transcripts were used as a basic source of information. In addition to the ASLB hearing transcripts, filings with the board by the NRC staff. Te.xar Urflities Electric Company (TU Electric, previously Texas Utilities Generating eO Company or TUGCO), Citizens Associationfor Sound Energy (CASE), and Cygna Energy Services (Cygna) were iricluded. The documents also encompassed transcripts of meetings1 between any of the above mentioned panies, the NRC Sqfery Evaluarion Reporr (SER, NUREG.

ll Each source document listed in Attachment A was reviewed and extemal source issues were documented on Issue Records to capture a minimum of one citadon of each distinct issue. For every Issue Record, an E-type DIR was issued to assist the Third Pany in tracking closure of the - {'

issue. '!he document reference and specific page(s) on which the issue is discussed were recorded on each DIR. Following the identification and documentation of each individual issue, j

DIRs related to cable tray /suppons were gmuped into common issue categories. Dere are thiny-one such categories.

Extemal source issues were not evaluated for safety significance because the Project is performing a 100% design validation of cable trays and has incorporated issue resolution directly into the design validation procedures. In essence, all issues have been treated as potentially safety significant and addressed accordingly.

3.1.2 Design Criteria / Commitments identification Introduction

/ ,

The Bird Pany identified design criteria and commitments applicable to CPSES cable tray /suppons to establish acceptance criteria for the subsequent review of Project procedures and suppornns documenu O n. i..u.ia.ooio.x De design criteria and commitments applicable to CPSES cable tray / supports were identified from a review of the PSAR, applicaMe Regulatory Guides, and referenced industry codes and i standards. This was done as part of the Dird Party identification of all Civil / Structural design criteria and commitments applicable to DSAP VIII activities. His effort resulted in the l deveW_ of the design criteria list, DAP CR-C/S-001 [Rqf. 7J.85]. De criteria and commitmer.ts applicable to CPSES cable tray /suppons are a subset of this criteria list.

De desigr. criteria fbr cable tray /suppons were colleedvely evaluated for completeness, accuracy, and conssewy. Dis was accomplished using the design criteria review checklist, DAP-CLA C/S-012 [R<f. 7J.8d).

3.1.3 As-Built Procedures Review 1 l

introduction Design validation of cable tray / supports is based on as built information for 100 percent of the cable tray systems installed in CPSES Units 1 and 2. The program for obtaining as built information was undertaken by the Pmject in response to extemal source issues that questioned the conelation of the original design drawings to the actual constructed conditions. This program ensures that the information used in design validation accurately represents CPSES cable tray t systems.

\

O t

O a. vie u.ia o i av i The Third Party aview of the program for otxaining as-built information included the review of TU Electric engineering walkdown procedures, TU Electric QC inspecdon procedures, and those special studies related e defining appopriate physical properties for inaccessible anributes (i.e.,

attributes that are covered by fireproofing material, or are otherwise inaccessible, and cannot be visually examined). The scope of the review was limited to evaluating the adequacy of the engineering walkdown and QC inspection procedures for those attributes of cable trzy/suppons that are specifically related to design. Field reviews of selected suppon and span length drawings were performed as well, to provide additional assurance that the procedures could be effectively implemented.

The Third Party review was performed using engineering evaluadons. The acceptance criteria for review of procedures were based on the physical attributes judged by the 'Ihird Party to be important to design validation. The acceptance criteria for determining appropriate physical properdes ofinaccessible attributes were based on lower bound or worst-case estimates of each i

type ofinwessible attribute. The acceptance criteria for review of as built hanger and span i length drawings were based on conformance with the requirements of the applicable inspection

=

procedures.

?

The specific Project pmcedures reviewed and the corresponding DAP documentation are listed in Anachment C.

I 3.1.4 Design Validation Procedures Review O introduction Ebasco and Impell have developed independent procedures to govem their regective portions of the cable tray /suppons design validadon program. These procedures define and control the design validation process, interfaces, and technical methods employed.

Review Methodology A design review evaluation checklist was developed for review of cable tray / supports design validation proc 6dures using the applicable criteria and commitments of DAP-CR C/S-001 (See Section 3.1.2 above).1he applicable criteria were bmadened into checklist attributes, as appropriate, by stating the specific requirernents of the codes, standards, or regulatory guides.

Additional anrlbules stated e resolution of extemal source issues or pemnent results of special study reviews wess also included in the checklist.

All procedural documents used by Ebasco and Impell in design validation were reviewed using the design review evaluation checklist, except for a few documents or portions of documents that i

were examined using engineering evaluations. Engineering evaluations were used to augment checkhst review of certain aspects of design validation, such as tray and fitting qualificadon, where a review of specific iterns was desired.

i Application of the design review evaluarlon checklist to a specific design procedure document involved assessment of the document's compliance with the checklist attributes. For each p antibute, the review determined if the design was in compliance with design commitments. If

\

compliance was satisfactory, the reviewer indicated "S AT". If the design was not in compliance, or was indeterminate, the disposidon was "UNSAT." Each UNSAT determination was followed TN 67-7259 3-4 DAP RR C/S-001, REV.1

L l .

by issuance of a C-type Discrepancy / Issue Resolution (DIR) Repon that docum for future evaluadon and closure tracking. An attribute that was not applicable to the sp document or design was marked "N/A." If an attribute was outside the denned scope o was marked "N/C"(Not Checked), indicating that it was not evaluated.

'In addition to the review of pmcedures, the Third Pany evaluated the organization, tra contml of the design validadon process used by both Ebasco and Impell.1his was done in a qualitative manner and documented in engineering evaluations. The purpose of this review w to assess if the Ebasco and Impeu organizations could perform effectively with the level of detai provided in their respective pmcedures.

The specific Ebssco and Impell procedures that were reviewed and the contsponding DAP documentation are listed in Attachment C.

3.1.5 Special Studies Review introduction Ebasco and Impell have performed numerous special studies to support the

design validation of cable tray / supports. These studies provide bases for the 5technical meth and assumptions included in theirprocedures or are used to resolve specific extemal source issues.

Review Methodology The Third Pany review of special studies was implemented using engineering evaluations. The acceptance criteria fbr engineering evaluations were developed on an individual evaluation basis and,in general, consist of the applicable pomons of the design criteria and commitments, = i discusaed in Section 3.1.2, as well as additional criteria deemed by the reviewer to be pertin the special study. AB of the special studies used by Fhaarn and Impell as bases for theirj validanon procedures or to resolve extemal source issues were reviewed by the Third Party '

Introduction  !

A series of test programs were performed by the Pmject in support of the cable tray / suppor design ymmtarian program. These tests were performed for the following reasons:

to resolve externalsource issues,

• f to validate engineering parameters and analytical modeling assumptions employed in the design validation process, and e )

to pmvide infonnation and data required for specific component qualification.

The tests were defined and controlled by test specifications developed by Ebasco with the exception of tests of clamps for which the specification was developed by Impell. The tests wert performed by Anco Engineers,Inc. (ANCO) and Corpyare Consufring andDevelopment Company, Ltd. (CCL). The tests performed by these two testing laboratories were as follows:

• Monotonic and Cyclic Tests of Cable Tray Clamps, and

• Static Tests of Cable Trays and Fittings.

i In all cases, the organization performing the testing developed their test plans from the test specifications, conducted the tests, and produced test results reports. 'the test results have been used by Ebasco and Impell in related special studies and/or have been incorporated into their i respective procedures for design validation.

Review Methodology The ' third Party review of the test specifications, procedures, and results was performed using engineering evaluations.

'!he specifications and procedures were evaluated for their capability of achieving the5 specified objectives of the test programs. 'the results were reviewed to verify that the tests were performed in accordance with the procedures and that required data are documented in the test reports.

The specific test program documents that were reviewed and the conesponding DAP documemation are presented in Antar hmerit C.

3.1.7 lasues Resolution Review The '!hird Party activities associated with the review of extemal source issue resolution included the review of Ebasco's and Impell's procedures, special studies, and teit program results as they relate to each issue group. 'Ihese reviews were performed as an integrated part of the Third Party review activities previously described in Sections 3.1.3 through 3.1.6.

3.2 Results The results of'!hird Party review are described separately for each overview activity in the following sections. .

3.2.1 Extemal Source lasues identification From the review of external source documents listed in Attachment A, approximately 200 issues related to cable trayhupports were identified. Most of these issues were identified from the review of Cygna documents generated as part of the JAP. A number of the same issues and a few additional issues were also idersified in ASLB proceedings transcripts, the NRC CPSES Safety Evaluation Report, and public meeting transcripts.

'Ihirty-onc issue groups were established based on the twenty nine issue groups that Cygna had used plus two additional inue groups. Cygna's grouping ofissues was adopted for all related pd extemal source issues since their documentation pmvided the most comprehensive description of -

cable tray /suppons issues. 'the issue groups and the conesponding DIRs that were generated to document and track the issues are presented in Attachment B. It is noted that a specific DIR

(

TN-87 7259 3-6 DAP.RR-C/S-001, REV.1

number may h undermore than one issue group. This indicates that certain aspects issue relate to different groups.

'Ihe extemal source issues can be classified into two broad categories of concems:

1) concems 'that a specific FSAR technical commitment, industry code or standard requirement, or regulatory position was not implemented in design methods, and

2) concems that as built conditions were not adequately reconciled with the design.

There is sufficient information for each concem in the public record (documents listed in Attachment A) to enable the Third Party to delineate each issue.

3.2.7.1 Controlling Load Case For Design ISSUEDESCR9 DON In the origlast design of CFSES cable tray supports, the OBE was assumed by Gibbs and Hill to be the govening seismic load case for all suppon components (e.g., members, welds, and {'

anchorages). This assumption was based on the comparison of the 60% increase in OBE

! allowables, permitted by the PSAR (Ref. 7J.2] for SSE design of most structural steel oornponents, and the r so of SSE load to OBE load which is,in general,less than 1.60. Concems were raised regarding the use of the OBE as the goveming load case, since the 60% increase in allowables is not appspriate for some support components (e.g., Richmond Inserts and Hilti I expansion anchors).

I 3.2.7.2 Seismic Response Combination Method ISSUE DESCRIPTION

. Concems were raised regarding the consideration of seismic loads in Gibbs and Hill's Working Point Deviation Study [Ref 7.63) and in original design calculations performed by Gibbs and i Hill. The specific concerns were the following:

• Closely Spaced Modes -In the response spectrum analyses performed as pan of the Working Point Deviation Study, closely-spaced modes were not combined in accordance with the requirements of Regulatory Guide 1.92 [Ref. 7.65).

• Seismic and Dead Emed Combination - In design calculations, a 1.0g acceleration for dead load was impraperty ad.ded to vertical seismic acceleration. 'the sum was then combined with the two horizontal seismic components using the SRSS method, RESOLUTIONMETHOOOLOGY Ebasco and Impell have addressed these concems as follows:

• Closely-Spaced Modes Ebasco and Impell combine closely spaced modes in accordance with the requirements of Regulatory Guide 1.92 when response spectrum analysis is used to validate the design of cable tray system components.

• Seismic and Dead land Combination - Ebssco and Impell add dead load response to the SRSS combination of the three orthogonal seismic response components, considering both the posidve and negative sign of the seismic resultant.

3.2.7.3 Anchor Bolt Design ISSUE DESCRIPTION Concems were raised regarding Gibbs and Hill's " Structural Embedments" Specification 233-SS 30 (SS 30) and other attributes of anchorage and/or anchor bolt design. The following is a summary of these concems.

Eccentricity of Frame Connection Point - Design calculations for anchor bolts did not address eccentricity between frame connection point and anchor bolt pattem centroid.

SSE Hilti Safety Factors - The safety factor for Hild expansion anchors may have been violated at specific locations, considering the goveming load case (OBE vs. SSE).

Inconsistent Application of ACI 349 76 Criteria from ACI 349-76 (Ref. 7.6.7],

Appendix B, were used to qualify some anchorage designs but were violated in other

- designs (e.g., design of anchorages with single expansion anchors). I Richmond Insert Factor of Safety - The design safety factor for Richmond Inserts may have been violated at specific locations, considering the goveming load case (OBE vs.

SSE).

O V

e Richrnond Insert Design - Prying action was not considered in design of Richmond Inserts.

Certain connections that use Richmond Inserts were qualified using the results of an on-site testmg program that provided higher allowable loads than the original design criteria.

Allowable load reductions were not applied to Richmond Inserts in cluster arrangements, Richmond Inserts embedded in the sides of concrete henmm, and Richmond Inserts that had less bolt-to-bolt spacing than required by design criteria.

Connection Designs - Installation tolerances for anchor bolt spacing and member placement on base connections were not considered in design calculations.

Design drawings allow the use of either Hilti expansion anchors or Richmond Insens for certain base connections However, design calculations were only provided for Hilti expansion anchors.

Prying Feetor Justification - No technical justification was provided for a prying action facsor of 1.5 used by Gibbs and Hill in base connection design calculations.

Anchor Bolt Substitution - For certain details on design drawings, notes and design 4 changes allow substitution of Richmond Inserts and Hild expansion anchors, and mixtures of the two. Anchor bolt substitution may be inconsistent with design calculations due to differences in minimiun spacing, tolerance, and embedment length requirements for each anchor type. As a result, allo wable tensile loads in Richmond Inserts and Hilti bohs may be over esdmated.

p

• Base Angle Boundary Condition Assumption - For trapeze type supports with two-bolt l Q base angles, design calculations assumed, without appropriate justification, free rotation TN-87-7259 3-11 DAP RR-C/S 001, REV.1

k

- i of base angles about an axis perpendicular to the plane of the hanger, ignoring the ]

stiffness of the base angle.

• Installation of Expansion Anchors in Diamond Cored Holes Construction procedures allowed re installation of Hilti expansion bolts in pre used holes. Anchor strength may be decreased due to an oversized core bore bit being used to remove previous bolts. Bit diameter was not controlled during installation. No records of which bolts were installed in core bored holes exist.

• Reduced Allowables for 1" Hilti Kwik Bolts Revised (reduced) allowables for 1" diameter Hilti Kwik bolts were not considered in the re evaluation of existing supports.

Designs performed since the revision should have addressed the reduced allowables.

RESOLUTIONMETHODOLOGY l

'the responsibility for resolving concems related to SS-30 has been assigned by TU Electric to the Civil / Structural portion of the Corrective Action Program (C/S CAP) which is being performed by Stone and Webster Engineering Corporadon Ebasco and Impell will revise their design vaudation procedures as remry to incorporate pertinent changes to SS-30 made by the C/S-CAP. The following summanzes Ebasco's and Impell's resolution of other concems raised with respect to anchorage and/or bolt design: 3

3.2.7.4 Design Of Coinoression Members m 7 ISSUE DESCRIPTION Concems were raised regarding the original design of cable tray hanger compression members.

The specific concems follow; i - .

• Slenderness Ratio - In calculating the slendemess ratio (KI/r) of charme! section compression members used for trapeze type suppons, unrealistic assumptions were made for unbraced length and end conditions. As a result, the minimum slendemess ratio specified for compression members by the AISC Specification [R( 7.6.1] may have been violated.

• Sidesway Restraint - In calculating the slendemess ratio of compression memters of trapeze supports, the effectiveness ofin-plane sidesway restraint was not validated for various suppon designs.

• Cantilever IAngth Por cantilever suppons, a distance from concrete face to tray centerline was used as the cantilever length, instead of the distance to the outside clamp.

Also,in calculating the minor axis slendemess ratio of the cantilever member, the tray was assumed to provide lateral bracing at clamp locations, without properjustification.

Wald Underent - Por trapeze suppons, the reduction due to weld undercut of section properties ofcompression members at in plane brace attachment points was not considered.

Out-of Plumbness - The installation tolerance of 2 degrees from plumb for vertical members was not considered in design calculations. Nojustification was provided for the acceptability of a 2-degree tolerance.

Hanger Post Effective Length In the Working Point Deviation study [Ref. 7.63], the  !

unsupported lengths of trapeze suppon posts were reduced by 5 inches (i.e., the width of p the base angle's leg). The assumption that post length can be measured from the tip of

\ the base angle's outstanding leg may not be proper for cenain post / base angle cornbinations. l TN 87 7259 3 14 i DAP-RR-C/S 001, REV.1 I

• Brace Slope - In the calculations for compression braces, the largest axial load was found as a funcuon of the brace slope. However, cases with lowerloads but reduced axial capacities due to longer member length were not considered.

RESOLUTIONMETHODOLOGY The following methods were used by Ebasco and Impell to address the concerns discussed above: I e

Slenderness Ratio - Design validation of hanger members is performed in accordance l with the AISC Specification /Ref 7.6.1] using K-factors and KIJr(idendemess ratio) limits determined by special studies.

K factors fcr transverse hanger members are based on the assumption that trays restrain hangers against out of plane buckling (i.e.. buckling about the weak axis of channel members). This assumption has been confirmed by full scale dynamic tests of cable tray systems [Rgf. 7.4.2] which showed that little or no slip occurs between trays and transverse hangers during seismic shaking. K-factors and slendemess ratios forin plane buckling (e.g., buckling of posts in longitudinal hangers about the weak axis of channel members) are addressed in the issue concerning the effectiveness of siderway restraint, which follows.

i Slenderness ratios for compression members have been limited to 200. Tension members -

are allowed slendemess ratios up to 300. A member is considered to be a tension member when it is normally subjected to tension under stade load, and static plus  !

dynamic load results in a compressive stress less than 50% of the allowable compressive O e Sidesway Restraint - K factors used by both Ebasco and Impell in design validation are based on studies that explicitly account for in plane sidesway. In these studies, springs were used to model the restramt provided by trays.

Cantilever IAngth - Impell uses a member length from the face of the concrete to the outside clamp. For cantilever supports with Type A or O clamps, Ebasco uses a member length from the face of the concretc to the inside clamp; for cantilever supports with Type C clamps, Ebasco uses a memberlength from the fax of the concrete to the outside clamp.

11ie K-factors used by both Ebasco and Impell are based on studies that justify the ,

assumption that the tray prevides lateral support to cantilevered members.

Wald Undercut - Ebasco has perfonned a study of the base metal defects identified by QC inspection of CTH's and has concluded that the effects of weld undercut on CTH capacity are not significant and can be ignored in design validation.

Out et-planboess - Out of-plumbness in excess of 2 degrees is noted on as-built drawings and explicitly considered in design validation calculations. The effect of 2-degree out.cf plumbness on member stresses was shown to be insignificant in special studies performed by Ebasco.

Hanger Post Effective langth - Ebasco and Impell measure the length of hanger posts

' from the face of the concrete.

A e C Brace Slope - The design adequacy of bracing members has been validated using as built infonnation by both Ebasco and Impell.

THIRD PARTYEVALUATION i

'O-The Third Party myiew of Ebasco's and Impell's design validation procedures and relate studies concluded the following:

l I

• Slenderness Ratio -De nird Party found the K factors and KlJrlimits resulting from special studies (Rgs. 7.2.22, 73.72, 7J.74, and 73.76) for transverse hanger members to be acceptable and properly incorporated in Ebasco's and Impell's design validation procedures.

De hird Party concurs with the assumption that trays provide lateral stability to hangers.' See also Section 3.2.7.18.  :

Impell's design validadon procedures [R( 73J] include K factors and Kl/rlimits for most hanger conAgurations, but in a few cases (e.g., for very long hangers) explicit rules l are not provided. Third Party review of selected Impell calculations (Rg. 73.91) conarmed that conservative K-factors wete used for hangers not explicitly covered by the design validation procedures.

• Sidesway Restraint - The Third Party found the K factors resulting from special studies (Rgs. 7.2.22 and 7J 70) to account forin-plane sidesway adequately and to be properly

.. incorporated in Ebasco's and Impell's design validation procedures. The nird .

i Party concurs by trays.

• Cantilever Langth - 1he lengths specined in Ebasco's procedures for cantilever members were reviewed by the Third Party and found to address this concern adequatel The lengths speci5ed in Impell's procedures for cantilever members and the related K-facais determined by special studies (Rgs. 73.74 and 7J.76) were reviewed and found acceptable. De Dird Party concurs that trays provide restraint to cantilevered compression members. See also Section 3.2.7.18.

• Weld Undercut - De hird Pany has reviewed Ebasco's special study on base metal defects [Ref. 7.2.49] and concurs that weld undercut need not be considered in design validation of CTHs.

• Out of plumbness - De nird Party reviewed Ebasco's special study on dimensional tolerances (R(. 7.232) and corcurs that the effect of a 2-degme out of plumbness tolerance on Icember stresses is insignincant.

• Hanger Post Effective langth - The Third Party review of Ebasm's and Impell's procedens conSrmed that appropriate memberlengths are used in the design validation of tripene hangers and cantilevers. l Brace Slope - The Dird Party concurs that use of as built information by Ebasco and Impell in design validation resolves this concern.

CONCLUSION Ebasco's and knpell's design validation procedures and related spec.ial studies resolve all concems raised by the issue of design of compression members. The issue of design of compression members is closed.

~ Vertical And Transverse Loading On Longitudinal Type Supports ISSUE DESCRIPTION Gibbs and HH1 considered only longitudinal seismic load in the design oflongitudinal trapeze type supports. Concems have been raised that these suppons should also be designed for transverse and vertical seismic load.

RESOLUTIONMETHODOLOGY Ebasco and Impell address this issue by evaluating suppons for the combined effects of venical, transverse, and longitudinal seismic loads.

THIRO PARTYEVALUATION The Third Party review of Ebasco's and Impell's design validation procedures confirmed that longitudinal trapeze-type supports are required to be validated for the siraultaneous application seismic loads in all three onhogonal directions.

CONCLUSION .

Design validation oflongitudinal suppons for three components of earthquake motion ade addresses concems raised by this issue. The issue of venical and transverse loading on longitudinal type supports is closed.

3.2.7.6 Support Frame Dead And inertial Loads ISSUE DESCRIP710N Concems were raised regarding Gibbs and HiD's design of cable tray suppons for out-of-plan inertialoads and deadloads:

e i Out of Plane Inertial lmads - Outef plane inertial loads (parallel to tray) were not considered in design of two way supports. Out of plane loads transmitted fmm two-way i suppons through trays were also neglected in design oflongitudinal suppons. '

• Dead leads - Support dead loads were not considered consistently (e.g., suppon weight was ignored, treated as additional load on tray, calculated based on actual member l j

weights, or applied as dead load equal to one half of the support's weight). When design "

changes occuned, designers arbitrarily reduced the weight used in analyses.

RESQLU110NMETH000 LOGY The following meshods were used by Ebasco and Impell to address the concems described above:

• Out of Plane Inertial lands - Ebasco makes bounding assumpdons for out-of-plane inenialloads in the design validation of transverse (two way) and longitudinal suppons when ESM (Equivalent Static Method) analysis is used. For design validation of transverse supports, out of-plane response of transvene hangers is evaluated using longitudinal hanger displacements and accelerations. For design validation of longitudinal supperts, out of plane load from transverse hangers is assumed to be transmitted through trays to longitudinal suppons.

TN47 7259 3-17 DAP RR C/S 001, REV.1

Ebasco amiImpell model support mass and assume that transverse suppons are connected to trays in all directions for design validadon of cable tray systems when RSM (Response Spectra Method) analysis is used. '!he assumption of full connectivity between tray and transverse suppons was validated by full-scale dynamic tests of cable tray systems and related analytical studies. See also Section 3.2.7.18.

• = Dead Loads Ebasco's and Impell's design validation procedures require suppon dead loads to be used in design validation.

THIRO PARTYEVALUATION Methods by which Ebasco and Impell addressed the concems of this issue are evaluated as follows:

Out-of Plane Inertial 14 ads - The Third Pany review of Ebasco's design validation procedures found that out of plane inenial loads are adequately considered in ESM analysis of cable tray systerbs.

3.2.7.7 Design Of Angle Braces Neglecting Loading Eccentricity-

{

ISSUE DESCRIPTION l

Concems were raised regarding Olbbs and Hill's design of angle braces neglecdng loading eccentricity:

Longitudinal Braces - Bending stresses induced in longitudinal angle braces due to end-connection eccentricity were not considered in design calculadons. Also, double angle braces without lacing (fillerplates) required by the AISC Specificadon [Ref. 7.6.1] were improperly analyzed as composite members.

• In Plane Braces - Bending stresses due to end connection eccentricity were not considend in the design ofin-plane angle braces of transverse and longitudinal cable tray supports. Also, the arigle members were not checked considering principal axis section moduli.

• Twist Buckling For some angle brace connections, welding is used along one leg of the

- angle, at one end of the brace, and along the opposite leg of the angle, at the other end of the brace. Braces with such end conditions were not evaluated for twist buckling which can occur for some brace geometries at load levels below the critical Euler buckling value.

T RESOLUTIONMETHODOLOGY Ebasco and Impell addressed the concems raised above as follows:

Longitudinal and In Plane Braces Ebasco validates the design of angle braces for momer.ts. induced by end-connection eccentricity.

Impell investigated the effects of end-connection eccentricity on angle braces in their study M 12 [Refe>ence 73.23), and found the effects to be insignificant since the braces do not carry large axial loads. On this basis, Impell does not model end-connection eccentricity and ignores the effects of such eccentricity in design validatiori of angle braces.

Ebasco evaluates single ang!e braces ucing principal axis properties. Impell evaluates single angle braces using geometric axis properties, and applies a correction factor to account for the difference between geometric and principal axis properties.

Ebasco and Impell evaluate double angle braces as a composite member only if filler plates am provided in accordance with the AISC Specification.

Twist Buckling . Ebasco and Impell evaluate angle braces for twist bueding when twist buckling is more critical than Euler buckling (i.e., for angle braces which are shon and stocky).

s THIRD PARTYEVALUATION Approaches used by Ebasco and Impell to address the concems raised in this issue are evaluated below:

Longitudinal and In Plane Braces The Third P=y review of Ebasco's design validation procedures confirmed that angle braces axe required to be checked for the effects of end-connection eccentricity.

The Third Party concurs with the findings of M 12 which showed that the effects of end-connection eccentricity of1.agle braces are small and can be ignored in design validation.

Impell's use of geometric axis properties with correction factors, rather than principal axis properties, was found acceptable.

The Third Party review of Ebasco's and Impell's design validation procedures confirmed that double angle brarces are required to be evaluated as a composite member only if filler plates are provided in accordance with the AISC Specifications.

Twist Buckling The Third Pany review of Ebasco's and Impell's design validation procedures and selected calculations [Refs. 73.90 and 73.91] confirmed that single angle braces are adequately checked for twist buckling.

CONCLUSION Ebasco's and Impell's design validation procedures and related special studies adequately address all concems raised in this issue. The issue of design of angle braces neglecting loading eccentricity is closed.

3.2.7.8 Dyrisimic Amplification Factors (DAF) And Ratios Between Continuous Tray Support Reactions And Tributary Tray Support Reactions  ;

ISSUE DESCRIPTION

\

In the original design o'f cable tray suppons, Gibbs and Hill detennined seismic response using equivalent static analysis with a dynamic amplification factor (DAF) of 1.0 times the peak of the goveming design spectrum Concerns have been raised regarding the use of a DAF of 1.0 since the FSAR [Ref. 7.1.2) requires a DAF of 1.5, unless additionaljustification is provided. An additional concem addressed the use of the tributary span method, which may not adequately consider the effects of system response on the distribution of tray load to individual supports.

RESOLUTION METHODOt.OGY f

'Ihe designs of the majority of cable tray supports within Ebasco's scope are validated by Equivalent Static Method (ESM) analysis. In ESM analysis, seismic response is determined by multiplying the goveming design spectrum's ordinate at the lowest frequency of the cable tray system by a response multiplier (i.e., DAF) of 1.25. If the lowest frequency falls below the peak of the spectrum, then 1.25 times the peak of the spectrum is used to determine seismic response.

- Special studies were performed by Ebanco to assess the limits of the applicability of the ESM i with a multiplier of 1.25 to account for both multi mode and system type load distribution effects.

Outside these limits a muldplier greater than 1.25 is regaired for ESM analysis, or response spectrum analysis is perfonned.

/

Impell determines seismic response by equivalent static analysis, with a DAF of 1.5, only for '

certain complex ganged hangers. For all other cases, seismic load is determined by response  !

spectrum analysis.

When response spectrum analysis is used by either Ebasco or Impell, system effects, including stiffness of trays relative to hangen, varying span lengths and configurations, and different support stiffnesses, are explicitly accourned for by a dyramic model of the cable tray system.

THIRD PARTYEVALUATION l The Third Pany review of Ebasco studies contained in Volume I, Books 9 and 10 (R(s. 7.2.26 and 7.2.27) found that the use of the ESM with a response multiplier of 1.25 is appropriate for determining seismic response of cable tray suppons that are part of regular cable tray configurations (e.g., straight tray runs with equally spaced, identical supports). Additional stud;es were performed by Ebesco to assess the applicability of ESM, with a response multiplier of 1.25, to suppons that me componeras ofirregular cable tray systems or otherwise not covered by the work contained in Volume I, Books 9 and 10. These trudies, which are documented in Volume I, Books 15 and 23 [Rgfs. 7.2.31 and 7.2.37), and a supplementary screening procedure (Ref 7.2.43]

defend and delineate the limits of applicability of the ESM, and prescribe methods for determining response of cable tray system components falling outside these limits. The results of these studies and the requirements of the screening procedure were reviewed by the Third Pany and found to be acceptable.

'Ihe Third Pany review of Impell Project Instruction PI 02 [Ref. 7J.4] concluded that the use of A equivalent static analysis, with a DAF of 1.5, is appropriate for determining response of complex

'V ganged hangers.

t CONCLUSION Ebasco's and Impell's design validation procedures and related special studies adequately addre all concems raised by this issue. The dynamic amplificadon factor issue is closed.

3.2.7.9 Reduction in Channel Section Properties Due To Clarnp Bolt Holes ISSUE DESCRIPTION Gibbs and Hill's original design calculations for channel members did not consider the reduction of the section moment ofinenia, as required by the AISC Specification [Ref. 7.6.1], when bolt holes are present in the flanges of these members.

RESOLUTION METHODOLOGY Ebasco and Impell evaluate cable tray support ders using channel section moment ofinertia properties reduced to account for the presence of either a used or unused clamp bolt hole.

Reduced section propenies were calculated for various channel sizes assuming a clamp bott hole to be present in one flange, and these reduced section propenies were used to derive limits on interaction ratios permitted for design validation of cable tray support tiers.

THIRD PARTYEVALUATION The derivadons of reduced section propenies documented in Ebasco's Volume I, Book 25 (Re 7.2.11] and in Impell S:udy M 65, [Ref. 73.65], and the contsponding limits on interaction ratios pV were reviewed by the 'Ihird Pany and found to be cortsistent with the AISC Specification. The

'Ihird Pany confirmed that the limits on interaction ratios and the associated procedures for j

j applying these limits have been appropriately incorporated into Ebasco's and Impell's respective design validation procedures.

CONCLUSION Design validation of cable tray hanger tiers for section propenies reduced to account for the presence of a clamp bolt hole in the flange adequately addmsses concerns raised in this issue.

The issue of reduction in channel section properties due to clamp bolt holes is closed.

3.2.7.10 ' System Concept ISSUE DESCRIPTION Concems west raised regarding the assumptions associated with the " system concept" used in analyses by Gibbs and Hill tojustify cable tray suppon design assumptions. Specific concems were as follows:

Load Eccentricity on Support - Assumptions were made that the moments caused by the eccentricities between the load application points (i.e., tray centroid) and the suppon members (i.e., center of resistance) would be balanced by force couples at adjacent suppons. These assumptions are inconsistent with cenain assumptions taade regarding tray to-hanger clamp behavior. See also Section 3.2.7.24 (Vertical Eccentricity, Horizontal Eccentricity, Torsion of Tier Members) and Section 3.2.7.18.

• Lateral Bracing of Cantilevers -In the design of trapeze and cantilever support members for conipression loads, trays were assumed to provide lateral bracing to the TN 87 7259 3-21 DAP RR C/S-001, REV.1

f q support members, withoutjustification. See also Section 3.2.7.4 (Slendemess Ratio) and C/ Section 3.2.7.18.

Transverse and Vertical Loads on Longitudinal Supports For the design of '

longitudinal trapeze supports, transverse and vertical loads were not considered. Only longitudinalloads were considered. See also Section 3.2.7.5. .

(

Prying Action It was assumed that the hanger attachment to the tray minimizes additional tensile forces in anchor bolts that' would otherwise occur due to rotation of base angles about theirlongitudinal axis. See also Section 3.2.7.3 (Eccentricity of Frame Connection Point).

Self Weight Seismic Loading Out-of plane seismic loads from self weight excitation of two-way trapeze support frames (i.e., transverse suppons) were not considered in the design oflongitudinal supports. See also Section 3.2.7.6 (Out of Plane Inertial Loads),

e Eccentrkities of Tier / Post Lap Joint - Bending and torsion introduced in support members due to the eccentricity between section neutral axes in tier / post lap joint connections were neglected without sufficientjustification. The tray was assumed to resist a portion of the additionalloads caused by the eccentricity.

RESOLUTIONMETHODOLOGY ~

c 7he following is a summary of the Ebasco's and Impell's methods for addressing these concems:

Load Eccentricity on Support - Ebasco assumes the longitudinal load to be applied on the supporting tier member at the centeriine of the clamp-to-tray bolt for one bolt OV connections and at the top of the tier flange for two-bolt connections. Impell assumes the longitudinalload to be applied coincident with the mid-height of the tray. These assumptions are jusufied by special studies. See also Section 3.2.7.24 (Vertical Eccentricity. Horuontal Eccentricity Torsion of Tier Members) and Section 3.2.7.18.

Lateral Bracing of Cantilevers - See Section 3.2.7.4 (Slenderness Ratio) and Section 3.2.7.18.

Transverse and Vertical Loads on Longitudinal Supports - See Section 3.2.7.5.

Prying Action - Ebasco and Impell consider the additional tension forces on anchor bolts due to prying action of base angles. See also Secnon 3.2.7.3 (Eccentricity of Frame Connection Point),

e Self Weight Seismic Landing - See Section 3.2.7.6 (Out of Plane inertial loads).

Eccentricities of Tier / Post Lap Joint - Ebasco's and Impell's design validation procedmes account for tier / post eccenuicity in the analyses of supports.

THIRD PARTYEVALUATION I '

7he Third Party review of Ebasco's and Impell's design validnion procedures and related special studies concluded the following:

Load Eccentricity on Support The justification for Ebasco load location assumptions, provided in Volume I, Book 7 [Ref. 7.2.23), was reviewed by the 7hird Pany and found I acceptable.

3.2.7.14 Non-conformance With AISC Specifications ISSUE DESCRIPTION Concerns were raised that the original design of CPSES cable tray supports did ret conform to i

cenain requirements of the AISC Specification [Ref 7.6.1]. These concerns are summarized i below:

TN-87 7259 3 27 DAP RR C/S-001, REV.1

I . Slenderness Ratio -The slendemess ratio limit of 200 for compression members may have been violated due to inadequate restraint by tray clamps (i.e., friction type clamps may not provide adequate restraint to suppons in the longitudinal direction). See also Section 3.2.7.4 (Slendemess Ratio).

Unbraced IAngth -incorrect assumptions for unbraced length resulted in overestimated bending stmss allowable for channels.

Bolt Holes - Reductions in section properties of beams due to bolt holes in flanges were not considered. Set, also Section 3.2.7.9.

Composite Compresion Members - Double angle braces were designed as composite members, without providing lacing. See also Section 3.2.7.7 (Longitudinal Braces).

Connection Eccentricities - Design of suppon members with axialloads did not consider connection eccentricities. 'This concem primarily affects single angle bnces and gusset plates. See also Section 3.2.7.7 (Longitudinal Braces, In Plane Braces) and Section 3.2.7.16 (Eccentric Connections).

Oversized Bolt Holes - Oversized bolt holes for anchor bolts and tray clamps were specified without adequatejustification. See also Section 3.2.7.31.

Bracing Members - A longitudinal brace was improperly designed for compressive stress as a secondary member.

RESOLUTIONMETHODOLOGY Actions taken by Ebasco and Impell to address the concems related to AISC Specification requirements are summarized below:

Slenderness Ratio - See Secdon 3.2.7.4 (Slenderness Rado).

Unbraced length - Ebasco and Impell validate the design of cable tray supports in accordance with Equadon 1.5 7 of the AISC Specification, which requires allowable flexural stress to be determined on the basis of the unbraced length of the compression flange.

1 Ebasco and impell consider the unbraced length of the compression flange of tmpeze support posts to be the distance fmm the face of the concrete to the centerline of the first tier and the distance between centerlines of adjacent tiers for other support levels. For L-  ;

shaped hangers, tier 40-tier distance is considered only temeca tiers supporting a tray.

• Connection Eccentricities - See Section 3.2.7.7 (Longitudinal Braces,In Plane Braces) and Section 3.2.7.16 (Eccentric Connections).

. Overslaed Bolt Holes - The effects of oveniud bolt holes are considered by Ebasco and Impell in qualification of tray clamps and in design validation of their connection to supports. Seismic qualificadon of tray clamps is based on t sts of clamps that are representative of as-built conditions, including oversizing of bolt holes.

Ebasco's and Impell's design validation procedures and related special studies and tests adequately addmss all concems raised in this issue. The usue of non cortformance with the AISC specification is closed.

3.2.7.15 Membei Substitution ISSUE DESCRIPTION A concem was raised regarding the original Gibbs and Hill design specificadon for cable tray supports which allowed substitution of structural members with members having potentially lower section moduli. Documentation of member substitutions was not adequate.

RESOLUTIONMETHODOLOGY Ebasco and Impell validate the designs of cable tray suppons using member sizes obtained %.a as-built drawings. When the member's size cannot be obtamed due to inaccessibility, a conservative value for the size of member is assumed.

THIRD PARTY EVALUATION The "nurd Pany review of as builting procedures, including the determination of propenies for inaccessible attributes, confirmed that appropriate member sizes are documented on the design drawings.

CONCLUSION Use of as-built propenies for cable tray suppon members adequately addresses concems raised in this issue. The issue of member substitution is closed.

3.2.7.16 Weld Design And Specifications Concems were raised regarding censin discrepancies in Gibbt t.nd Hill's design of cable tray supprt welds. Specific concems are described below:

Weld Details - The design drawings were missing the weld details for several suppon types.-

Weld Slaes 1he weld sizes shown on the assembly d.mwings differed from those shown on the design dravcgs and from those assumed in the design calculations.

Eccentric Connections - Load eccentricities were not considered in design of welds for brace / gusset plate / base connections, lapjoints between channels, and base angle conr=:' u-o Base Metal Thickness - The weld designs did not consider the thickness of the connected parts. Fillet welds with throat dimension greater than the connected plate dimension were specified.

Minimum Weld Length - The design calculations assumed an incorrect minimum weld length for beam / hanger base angle connection.  ;

RESOLUTIOkMETHODOLOGY The concems identified above are resolved or addressed by the following methods:

Weld Details, Weld Sizes, and Minimum Weld Length - Ebasco and Impell validate the designs of welds based on as built details, weld size, and length. For welds that are inaccessible, as-built properties are based on as-designed properties reduced to account  !

for potential discrepancies in weld size and length.

Eccentric Connections - Ebasco considers load eccentricities explicitly in the design validation of welds. Impell does not explicitly consider all connection eccentricities.

Some eccentricities were evaluated on a generic basis and shown to be insignificant.

Base Metal Thickness - Ebasco and Impell design validate welds considering weld and base metal thicknesses shown on as-built drawings.

THIRD PARTYEVALUATION The nird Pany review of as-built procedures (Refs. 7JJ and 7.1.4] and Ebasco's and Impell's i design validation procedures confirmed that the designs of welds are properly validated using as-built data. Specific review findings are summarized below;

• i Weld Details, Weld Sizes and Minimum Weld Length - The Third Pany confirmed that as built procedures require the documentation of all weld attributes necessary for design validation of welds (e.g., weld size. length, thickness and geometry). Concems regarding weld details and dimensions are adequately addressed by validating welds using as built properties.

.O

• Eccentric Connections - The Third Pany review of Ebasco's and Impell's procedures, related studies, and selected calculations confirmed that the designs of welds are adequately validated forloading eccentricities when such eccentricities are significant.

Review of selected Ebasco calculations (Ref. 7.5.90 ] found that eccentricities are explicitly considered in detennining loads on welds. Review of Impell's design validation procedures found that load eccentricities are explicitly considered in design validation of gusset plate welds and base connection welds. On the basis of the results of M 12 (Ref. 7.3.23], the nird Party concurs that the effects ofload eccentricities are insignificant and can be ignored in design validation oflap joints (e.g., tier-to post welds).

Base Metal Thickness - The Third Pany review of Ebasco's and Impell's design validation procedures [Ref. 7.2.1 and 73.5] confirmed that the base material thickness is adequately considered when checking stress in welds.

CONCLUSION All concems raised in this issue are adequately addressed by design validation of welds using as-built properties. his issue of weld design and specifications is closed.

• Prying Astion Capacity calculations for cable tray suppon attachments to embedded strip plass may not have considered the effect of prying action en the tension in Nelson studs.

• Stithning - Conflicting criteria may have been used by different groups for the stiffening ofembedded plates.

• Capacity Reduction - Calculations for cable tray supports attached to embedded plates did not consioer the capacity reduction for cenain attachment locations, as required by Gibbs and Hill's " Structural Embedments" Specification 2323 SS-30 [Ref' 7.6.2].

• Separation Criteria - Certain supports violated the minimum separation requirement of 12 inches between two adjacent attachments to an embedded plate.

• Tributary Span - Design calMations for embedded plates were performed assuming a 7'-6" tributary cable tray span. For trey spans exceeding this design value, embedded plates may support loads larger than those considered in the design calculations.

• Expansion Anchors No criteria were found regarding the minimum spacing requirement between embedded plates and expansion anchors installed on a surface gig.dicular to the embedded plate.

RESOLUTIONMETH000 LOGY i

Re responsibility for addressing the concerns raised in this issue, with the exception of tributary spans, has been assigned by TU Electric to the C/5-CAP. Ebasco and Impell will revise their design validation procedures, if necessary, to incorporate pertinent changes to SS-30 made by the C/5-CAP.

3.2.7.18 Tray Clamps ISSUE DESCRIPTION i Concems were raised about the assumptions used by Gibbs and Hill to model load trantfer between cable trays and supports at friction type clamps. ne load transfer assumpdons used to l i

< e y

Trayhpmvide out-of plane bracing to trapeze supports to reduce the buckling length of the verticalhanger members.

Trays pmvide lateral bracing to the compression flanges of the horizcntal beams.

e Trays provide outef plane bracing to suppons to prevent frame transladon, which would result in increased anchor bolt tensile loads.

Trays transfer out of plane inertial loads fmm tmnsverse supports to longitudinal supports on the same tray run.

The development of minor axis bending moments in the beams due to the horizontal eccentricity between the beam neutral axis and the clamp bolt is minimired by a bending

! moment in the cable tray.

l

• For venical loading, the development of torsion in the beam due to the eccentricity between the clamp location and the beam shear center is prevented by flexure of the cable tray. This assumes a full-moment fixity between the tray and the suppon beam.

For heavy duty clamps, all of the above assumpions were applied, and an additional assumption wr.s made as fonows e

lhe development of torsion due to longitudinalloads on three-way suppons using _

composite beam sections is prevented by flexure of the cable tray. This implies a full- 5 momen fixity between the tray and support beam.

The a?"wJons described above are valid only if the clamps can provide suitable displacement and mtation compatibility between the tray and support beam. In order to provide the assumed compatibility, friction type clamps must be emched sufficiently to develop friction between tray / beam and tray / clamp interfaces. The existence ofinstallation gaps may preclude the development of the normal contact force required for friction resistance, and hence invalidate the aforementioned assumptions.

RESOLUTIONMETHOOOLOGY Full-scale dynamic tests of cable tray systems were performed to evaluate experimentally the capacity of friction-type clamps to transfer force between trays and suppotts. . Subsequently, special saidies were performed by Impell to evaluate the tests and to conelate test results with vanous analytical modeling assumptions. Based on the test results and correladon studies.

Ebasco and Impeu have developed tray clamp modeling procedures that assume friction-type clamps to transmit fbree Intween the tray and the support in all directions.

fotnd the reladve longitudinal slip between the tray and the beam at the transverse supports to be small, even when instaBation gaps between clamps and tray were deliberately incorporated into the test specimens.

The Review ofImpeu System Analysisfrest Conelation Study (R<f. 7J.71] found that displacemera obtained from the full scale dynamic tests were, in general, enveloped by displacements predicted by analyses that assumed trays to be connected to supports in all directions.

ISSUE DESCRIPTION For cable tray systems installed in the Reactor Buildings, the loads associated with a Loss of Coolant Accident (LOCA) may be applicable, including pipe-whip, jet impingement, and thermal loads. A concem was raised that Gibbs and Hill considered only dead weight and seismic inecia loads in the original design of cable tray supports.

. loads postulated by the PSAR (Rg 73.2].

The PSAR states that thermal loads may be neglected when they are secondary and self limiting and the materialis ductile. Impell venfied in M 27 that these conditions are applicable to cable tray systems. Explicit analysis of cable tray systems for accident thermal loads is not performed by Ebasco and Impell.

THIRO PARTYEVALUATION I

The Third Party concurs that shielding or re routing of all the cable trays potentially affected by postulated pipe-whip and jet impingement loads adequately resolves concems for these loads. i 1he1hird Party also conuars that accident temperature loads are not applicable to cable tray i

systems that possess the capacity to absorb thermal movements without brittle failure of their components. Impell M 27 [Rg 7JJ8), provides adequate validation that thermal growth will not cause brittle isDwe of cable tray system anchorages.

3.2.7.23 - Loading in STRESS Models I

ISSUE DESCRIPTION Concems wem raised regardmg the analytical results obtained from finite element analyses of follow: hangers using the computer program TIRESS. Specific concems regarding thsie analyses some Tray Load AppHcation Points - On standard suppon models, tray loads were applied at the beam / post intersection instead of at an appropriate location within the span.

e Tributary Lead Calculations - Applied loads were based on tributary tray spans that did not account for installation tolerances.

Modeling of Support Frame Height - The standard suppon models did not use dimensions from the face of the concrete to the centeriine of members.

RESOLUTIONMETHOOOLOGY Ebasco's and Impell's approaches to address these concems are summarued in the following p e Tray lead Appucation Points - Ebasco's and Impell's procedures require load to be y applied at the centerhne of the trry for RSM analysis.

Tray 14sd Application Points - The Third Party review of Ebasco's and Impell's design validation pmcedures and related special studies (R<fs. 7.2.23 and 73.23) confirmed that load from trays is applied to the suppon beam at the actual location of the tray on the suppon, in all cues, except for the application of transverse load in ESM analysis used by Ebasco. In this case the Third Pany concurs that transverse load may be appropriately applied at the beam / post intersection of hangen, rmher than at the true tray i location. See also Section 3.2.7.24 (Vertical and Horizontal Eccentricity and Torsion of Tier Members).

CGNCLUSION Ebasco's and Impell's design validation procedures have adequately addressed the generic concems raised in this issue. The issue ofloading in STRESS models is closed.

3.2.7.24 Design Of Flexural Members ISSUE DESCRIPTION Concems were raised regarding Gibbs and Hill's design of flexural taembers for the effects of load application eccentricities, bolt holes, weld undercuts, and torsional shears on member  !

capacity, as well as the use ofimproper unbraced lengths of compression flanges to determine allowable bending stres6es. These concerns are discussed below:

e Vertical Eccentricity - Major axis bending of tier members under transverse load due to vertical eccentricity tw&a,;a the tray center and tier member neutral axis was ignored.

SuWnt analyses used tojustify this position were based on questionable assumptions about tier end fixity and unrealistic tray clamp behavior, e

Horizontal Eccentricity - Minor axis bending of tier members under transverse load due O

to horizontal eccentricity between beam neutral axis and clamp bolt holes in the top  :

flange was not considered. Hole gage tolerance was not considered, and the assumed behavior of tray clamps may have been unrealistic.

Torsion of Tier Me=r@ers - Torsion in the tier induced by vertical loads due to horizontal eccentricity between tier shear center and clamp location was ignored, and torsional moment under tray longitudinal loads due to vertical eccentricity was ignored.

As a resuh, tiermembers were only evaluated for direct shear. Combination of direct shear and torsional shear should have been considered.

Bolt Holes and Wald Undercut - Reduction in secdon property due to flange holes was no't considtred consistently and the effects of weld undercut in reducing section ,

l properties were ignored. See aho Section 3.2.7.9 and Section 3.2.7.4 (Weld Undercut). '

L e

1N ; f 4 langth of Compression Mange - Capacity reduedon due to the unsupponed length of the compression flange, per the AISC spectication, was not property crweidaed. Unrealistic tray clamp behavior assumpdons were used to justify l Ignosing capacity reduction. Compression of the bottom flange due to sidesway and seismic uplift was not considered. See also Section 3.2.7.14 (Unbraced Imgth) and Section 3.2.7.18.

Vertical Siid Horizontal Eccentricity - Ebasco and Impell pmcedures require that O. eccentricities be modeled in the analytical models to produce realistic major axis and minor axis bending of tier members.

l Torsion of Tier Members - Torsion due to vertical loads and horizontal loads has b addressed by Ebasco and Impell by incorporating eccentricities in their analytical models.

The torsional stresses (including warping effects) are required by Ebasco and Impell to be combined with the direct (flexural) shear stsesses.

THIRO PARTYEVALUATION

'The Third Party nyiew of Ebasco and Impell methods addressing the concerns of this issue are discussed below:

e Vertical Eccentricity For equivalent static analyses, Ebasco applies a major axis bending moment equal to the applied transverse load dmes the vertical distance from the

< j tier centmid to the bonom of the tray. For system analyses, both Ebasco and Impeu include a vertical eccentricity equal to the distance from tray mid height to tier centroid. j

'!he ' third Party review of Ebasco's and Impell's design validation procedures and related special studies [Rgs 7.238 and 73.23] confirmed that the effects of vertical eccentricity between the tray and tier are appropriately accounted for by incorporating such eccentricity in the analytical models.

• Horizontal Eccentricity - For equivalent static analyses, Ebasco applies a minor axis bending moment equal to the applied transverse load times the horizontal distance td a. the tier centmid and the clamp bolt location. For system analyses Ebasco includes a horizontal esw ;cky equal to the distance from the centroid of the web to the shear center of the tier. Impell neglects the honzontal eccentricity between the tier centroid and the location of the tray clamp and has shown in M 12 (Ref. 7J.23] that the effect of this eccentricity is not significant.

The % Party review of EbasWs and Impell's design validation procedures and related special studies [Rgs. 7.238 and 7J.23] confirmed that the effects of horizontal ie- ;&isy between the tray and tier are appropriately accounted for by irmorporating such eccentricity in the analytical models.

• Torsion etTier Members - Methods for calculating torsional stresses (including warping) hr various sections, e.g., channels and T- channels (Refs. 7J.23 and 7332),

were reviewed and found acceptable. The design validation procedures for combining torsional shear with flexural shear were also reviewed and found to be adequate.

and Impell's design validation procedures. 'Ihe issue of design of flexural members 3.2.7.25 Cable Tray Qualification ISSUE DESCRIPTION Concems were raised regarding Gibbs and Hill's qualification of cable trays. Specifically:

• Dynamic Amplification Factor - Cable trays were qualified by equivalent static analysis without using a dynamic amplification factor.

Cable Tray Capacity - Testing and qualification of trays was based on an 8'-0" simple span. For evaluation of trays with rpans greater than 8' 0", a capacity comparison was made based on the total load on the tray (rather than on the bending moment in the tray Capacity comparisons based on tray bending moment would result in lower tray ca for tray spans g1 eater than 8'-0".

Cable Tray Modifications There are several instances of modifica' ions to cable trays without justificadon or documemadon.

- Side rail extensions were added to increase tray depth, but no qualification for the modified tray segments was available.

- Modificadons were mede to standard splice connector plates without any documentation tojusdfy acceptability.

Cable Tray Moment ofInertia - Cable tray moment ofinerda for horizontal transverse loading ofladder-type trays was based on observed tray deformadons in tests assumin that all deformations was flexural; shear deformations were not considered. This assumption affects tray properties used in support frequency and displacement calculations.

RESOLUTIONMETH000 LOGY Ebasco's and Impell's methods for addressing these concems are described below:

Dynamic Amplification Factor - When ESM analysis is used (by Ebasco) cable trays are qualified using a 1.25 dynamic amplification factor. When RSM analysis is used (by! '

either RSM analyses.

Ebesco or Impell) cable : rays are qualified using loads obtamed directly from the Cable Tray Capacity Ebasco and Impell qualify cable trays with simple spans greater than 8'-0" based on the ultimate moment capacities obtained fmm tests of trays with 8' 0~

simple spans. Cable tray capacity for spans greater than 8' 0" are based on comparisons of tray bending moment, rather than total load on the tray.

Cable Tray Modifications Cable trays, fittings, and splice plates are qualified based on as built data which includes documentation of modifications to cable tray components.

e Side rail extensions are relatively light components and stmetural credit is not taken for these extensions. Ebasco includes the weight of side rail extensions in the qualification ,

l i

\

1 of trays. Impell excludes the weight of side rail extensions, based on the results of a special sandy.

Splice plates are qualified separately fmm trays and fittings based on a combination of test and analysis. Modified splice plates in Unit I were identified through walkdowns and dimensions were obtained by as-builting. Specimens representative of modified splice plates were tested to detennine capacity. A similar appmach is in progress for deviant splice plates in Unit 2.

• Cable Tray Moment ofInertia In the moment ofinertia computations, the measured test deformation, which includes both shcar and flexural, is equated to a flexural formula for a simply-supported beam. In the design validation procedure, trays are considered as Dexural members using these properties. Impell provides justification for this approach in a special study.

The 'Ihird Party concurs with the findings of M 39 [R<fs. 73.47) that the weight of side rail extensions can be ignored in qualification of cable trays.

'Ihe Third Party review of Ebasco's and Impell's qualification procedures for splice plates [Agfs 7.2.41, and 7J.8) conArmed that modified splice plates are property q= Mad by test and analysis. Review of the selection methods and test results (Refs.

7.2.40 and 7.4.9) conRaned that the capacity of modified splice plates in Unit 1 (T.J.

I Copy trays)is properly established. Use of the same approach (Rgf. 7.2.45) will resolve modified splice plates concerns for Unit 2 (Bumdy/ Husky trays).

• Cable Tray Moment ofInertia The 'Ihird Pany review of M-66 (R<f. 7J.66) confincad that trays may be appropriately modeled as flexural members (i.e., shear need not be considered in deterrnining response in the transverse direction of the tray).

The issue of cable tray qualification is closed.

3.2.7.26 Base Angle Design ISSUE DESCRIPTION Concems were raised regarding Gibbs and Hill's design of base angles. SperLal]y:

Stiffening Effects of Concrete - Base ang!:s were modeled as simply supported beams, ignormg stiffening effects of concrete, e i Principal Axis Properties - In design of base angles for various loadings, the principal I axis properties were not considered.

I Richmond Icsert Spacing In the " Working Point Deviation Study" (Ref 7.63] of brace connection eccentricities, the most critical spacmg of Richmond Inserts was not considered in determinmg base angle lengths.

Design Adequacy - Assurance was not provided that the base angles for all supports were adequately designed.

3 RESOLUTIONMETH000 LOGY I Ebasco and Impell have addressed the above concems as follows:

O e Stiffening Effects of Concrete - Ebasco and Impell ignore the stiffening effects of concrete in stress analysis of base angles, since this is a conservative approach for design validation. Concrete stifthess is included in calculations of base angle flexibility and used in the deter:nination of support stiffness.

Prindpal Axis Properties - Ebasco considers the principal axis properties of angles in design validation. Impell evaluates base angles using geometric axis properties and applies a correction factor so account for the difference between geometric and principal axis properties.

• Richmond Insert Spacing -The designs of base angles are validated based on as built data, which include Richmand Insen spacing.

• Design Adequacy 'the designs of all base angles have been validated in accordance with EbesWs and Impell's procedures.

i THIRO PARTYEVALUATION '

Ebasco's and Repell's methods addressing the concerns raised in this issue were evaluated by the Third Pany as follows:

• Stiffening Effects of Concrete - The Third Pany concurs that ignoring the stiffening  ;

effects of concrete is conservative for stress analysis of the specific base angle '

configuration of concem. See also Section 3.2.73 (Base Angle Boundary Condition Assumption).

• Principal Axis Properties Ebasco's use of principal axis properties of base angles in

(< design validation has been confinned by a review of the General Instructions [Ref 7.2.1].

l TN-871259 3-43 DAP RR C/S 001 REV.1

The1hird Pany has reviewed Impell Study M 12 (Ref 7.3.23] and concludes that ImpeH's use of a conection factor and bending stresses based on the geometric axis of r' base anglesis acceptable.

Richmood Insert Spacing - The Third Pany has confirmed, through reviews of as built pwceduwe [Rgfs. 7.1J and 7.1.4), that Richmond Insert spacing is being documented.

The use of as-built data in design validation addresses this concem adequately.

• Design Adequacy Since the designs of all angles are validated, this concem is not applicable. j j

CONCLUSION All concems identified in this issue are adequately addressed by Ebasco's and Impell's design  !

validation procedures and the use of as built data. The issue of base angle design is closed.

3.2.7.27 Support Qualification By Similarity ISSUE DESCRIPTION Concems were raised regarding Gibbs and Hill's qualificadon of supports based on similarity to other suppons. SpecificaUy:

• Qualification by Similarity - In design calculations, some suppons were qualified by their similarity to other suppons, without adequatelyjustifying the assumpdon of mellarity.

• Allowable Working Point Deviations - Allowable working point deviations for i

i individuauy designed zuppons were established based on similarity to standard suppon types, without adequate justificadon.

RESOLUTIONMETN000 LOGY j

Ebasco has smuped cable tray supports on the basis of similarity, considering support geometry, l connection details, and other relevant amibutes. When details of a gmuped suppon differ from the representative support, separate design validation of such details is performed.

Impeu does not use the PWon by similarity approach irs design validation.

i THIRD PARTYEVALUATION i

The 1hird Party review of Ebasco's grouping preadures, documented in Volume I, Books 4 and

{

8 (R<fs. 7.2.20 and 7.2.24), found that the suppon selected to si,.at a gmup of suppens is conservatively diossa with consideration of all relevant cable tray hanger attributes.

This issue is not applicable to Impell since each suppon is qualified individually.

CONCLUSION Concems raised in this issue are satisfactorily addressed by Ebasco's procedures for grouping  !

suppons. This issue is not applicable to Impell's design validation procedures. 'the issue of

• suppon qualification by similarity is closed.

3.2.7.23 TriticalSupport Configurations And Loadings

\

ISSUE DESCRIPTION

'lhe original design calculadons for trapeze type suppons considered only a limited number of critical suppon configurations and loading partems. Other suppons were qualified by comparl to these critical conngurations and loading patterns. *The following specific concems were raised I reganting these calculations:

• Critical Connguration - Aspect ratios used in calculadons for trapeze supports may not represent critical configurations for all suppon components. Frame width assumptions were unrealistic.

• Critiesi IAnding - Design calculations for frame members in trapeze suppons assumed l symmetricalloads; actual tray loads are often asymmetric.

RESOLUTIONMETHODOLOGY I Ebasco and Impell address the concerns described above as follows:

{-

• Critical Configuration - Aspect ratios have not been used to validate the designs of l

suppons. The conHguration of supports used for design validation are based on as built drawings.

• Critical Leading - Suppon loading conditions are based on as-built drawings which show the actual location of trays on tiers.

THIRD PARTYEVALUATION

.O The 'Ihird Party review of as-built procedures [Refs. 7.1J and 7.1.4] and Ebasco's and Impell's design validation procedures confirmed the following:

• Critical Connguration - Suppon geomeuies used in design validation adequately represent actual as built configurations.

• Critical Imading - Suppon loading condidons used in design validadon are based on the actual locadon of trays on suppon tiers.

CONCLUSION The use of as-built support configuradons and loading conditions adequately addresses concems raised in this issue. 'Ihe issue of cridcal suppon conagurations and loadings is closed.

3.2.7.29 Cumulative Effect Of Review issues ISSUE DESCRIPTION A concern was expressed by Cygna that small nonconservatisms resulting from separate issues may have a significant cumulative effect for supports affected by more than one issue.

3.2.7.30 Cable Tray System Damping Values  !

ISSUE DESCRIPTION Concems were raised regarding the validity of 4% damping for OBE and 7% damping for SSE used in design validation of cable tray systems.

RESOLUTIONMETHODOLOGY l

Results of full-scale cable tray system dynamic tests have demonstrated the validity of using 4%

and 7% damping in the evaluation of OBE and SSE seismic loads, respectively.

THIRD PARTYREVIEW The Third Party review of the usults of the cabic tray system dynamic tests (Rg. 7.4.2] and Impell's System Analysis / Test Conelation Study [Ref. 7J.7/] found that the effective damping of CPSES cable tray system configuradons exceeds the 4% and 7% damping ratios permitted by the FSAR for design of bolted-steel structures. The Third Party concurs with the use of 4% l i

damping for OBE and 7% damping for SSE design validation of CPSES cable tray systems. {

)

CONCLUSION '

Full scale dynasn' ic tests of sy.eaative cable tray systems confirmed the validity of design validating cable tray systems using 4% damping for the OBE and 7% damping for the SSE. 'Ihe issue of cable tray system damping values is closed. j 3.2.7.31 Modeling Of Boundary Conditions ISSUE DESCRIPTION Concems were raised agarding anchorage boundary conditions, including the effects of l

oversized bolt holes, and the techniques used to represent anchorage behavior in analytical '

models.

RESOLUTION METHODOLOGY i I Ebasco and Impell include anchor bolt stiffness and base plate flexibility in modeling boundary l

conditions of support anchorages. See also Section 3.2.7.3 (Base Angle Boundary Condition Assumpion).
