i ) i l'. 0 INTRODUCTION f This document provides the seismic' design verification criteria and { G i ( procedures for cable tray clamps, used in the Comanche Peak Steam Electric Station. The tested clamp types are the most commonly used types and represent the lower bound strength for either the transverse or longitudinal clamps. A list showing the lvwer bound equivalent for every type of clamp used in CPSES is indicated in Appendix A, Table Ill. In the event that the exact type of clamp is unknown, the lower bound 1 i transverse or longitudinal clamp shall be considered for the clamp design IR3 verification effort. l This document is developed based on monotonic and cyclic laboratory test results of Cable Tray Clamps performed as indicated in the Reference Document section below. 2.0 SCOPE This project instruction is applicable to Seismic Category I Cable Tray Systems of the Comanche Peak Steam Electric Station (CPSES). 3.0 REFERENCE DOCUllENTS l The following lists the applicable documents including the codes and regulatory guides. \\ .'v 3.1 Applicable Codes, Regulatory Guides and Related Documents I o ASME, Boiler and Pressure Vessel Code, Section III, Sub- ) section NF. ] o Regulatory Guide 1.29 - Seismic Design Classification, Rev. 3, September 1978. o AISC - !!anual of Steel Construction, 7th Edition including Supplements No. 1, 2 and 3. o Ebasco Calculation Volume I Book No. 21, entitled "CTH Clamps Qualification Methodology Development". o Ebasco Cable Tray llanger Seismic Design Criteria for CPSES Unit 1 Rev. 5 and for Unit 2 Rev. 8, and CPSES Units 1 and 2 CTH General Instructions Rev. 8. l R3 3.2 Test Reports o Report on Monotonic and Cyclic Tests for Cable Tray Clamps for CPSES, dated July 13, 1986, conducted by Corporate Consulting and Development Company Ltd (CCL).

l 4.0 TEST DATA I 4.1 fionotonic Tests i 1 (/"N) The qualification criteria for cable tray clamps is based on '~' monotonic test results, performed on selected sets of clamps (for l clamp type identification see Appendix D) which include the ~ following: 4.1.1 Transverse Clamps Type A, 4" and 6" high ) Transverse Clamps Type G, 4" and 6" high j Transverse Clamps Type C l 4.1.2 Longitudinal Clamps Type B, D, J, N and P. 4.2 Cyclic Tests l The qualification criteria is also based on cyclic test results, performed on selected sets of clamps, to determine their suita-bility to withstand seismic loadings. The following type of I cicmps were subjected to cyclic loadings: 4.2.1 Transverse Clamps Type A, C and G ) I 4.2.2 Longitudinal Clamps Type B, D and J ) 1 5.0 CLM1P LOAD ALLOllABLES 5.1 Methodology /~% 6 ) ('] Clamp load allowables have been obtained using the ASME Boiler and 4 Pressure Vessel Code, Section 111 " Load Rating" procedure, i described in Subsection NF Article NF-3280. l l Since precise yield loads (TLy) cannot br defined from the l available tests, an alternate load rating method is used to I establish load rating for clamps at the SSE level, as allowed by IR3 the ASME Boiler and Vessel Code. l l l 1 The alternate load rating method is based on ultimate loads (TLu), which are readily aveilable from tests. This alternate method is described in detail under Article NF-3282.4 of the ASME-Code. l The back-up calculations and the development of load carrying capscities of clamps are contained in

5.2 Equation to Determine SSE Allowables l 1 The following equ'ation shall be used in order to determine I j allowable clamp loads for the SSE level: 1 ( l b 5.2.1 Emergency Condition (SSE Level + Temp.) lR3 I ,TLu l p all 2 l I t Where TLu = ultimate capacity test load i 1 1 l Safety factor 2 is based on ASME Code, as described in l j paragraph 5.1 above. l l For clamp allowables see Table 1 in Appendix A. Note: Thermal loads do not need to be explicitly included in any design verification calculations since they are generically considered elsewhere. (See CTH General Instructions - l Section 11.F). Ihus, any instructions in this document l l regarding thermal loads may be ignored. 1 i 5.3 Use of Interaction curves to Qualify Clamps I Based on the failure test results, in which combinations of vertical, transverse and longitudinal loading was applied simultaneously on clamps, allowable interaction curves are developed to verify cable tray clamps load carrying capacity L subjected to seismic loads. ) 6.0 CLNIP DESIGN VERIFICATION FROCEDURE USING EQUIVALENT STATIC METil0D (ESM) l 1 6.1 Transverse Clamps Type A, G and C IR3 I 6.1.1 This verification procedure requires knowledge of l components Pot, Py and Pg. For load definitions of l Pot, Py and P g, see CPSES CTH General Instructions, i sheet 23. 6.1.2 Obtain absolute maximum loads (V, T ) on clamps in a a the vertical and transverse directions in accordance with the Ebasco Cable Tray llanger Seismic Design Criteria l loading combinations at the SSE level (or OBE if larger) and lR3 Section 6.1.4 below.

6.1.3 Tha connectivity'batween the tray and tha trensvarse hanger tier in the longitudinal' direction, as described I in Attachment Z of the Cable Tray Hanger General Instruc- -I tions, is attributed mainly to the friction between the j tray and the Cable Tray Hanger tier. Consequently 1 i the transverse clamps are-not engaged.in transferring any loads in the longitudinal direction during a seismic event. I 1 6.1.4 In order to consider the effect of both forces-and moments I applied by the: tray to the. clamp, all moments shall be l ) converted to f orce couples as follows. See Figure I for IR3 tray; coordinate system. For one clamp:- 1 l F M IV,= j + where M =lT* y g T " lFz! a h height of tray R3 = w width of tray 1 = l Thus for two clamps: 1 1 h*T l a v F + a x w l-l -l'= O 6,. 5 Use the following interaction formula for the clamp lR3 design verification: l I I i l v T l I f +f \\ Emergency 1 Condition s s where: V and T are the actual maximum loads on clamps (two claraps) ain the vertical and transverse direction as l a obtained in 6.1.4 above, for SSE level (or OBE if-lR3 4 larger). I I I I O 4 1590R

V and f are the equivalent allowable loads (for two 3 n clamps) at the SSis level. Obtain V and T on the basis of Table 1, Appendix A. IR3 3 s 6.1.6 Note that clamp allowables are given for "a pair" of clamps, not f or individual clamps. Dead loads plus downward seismic loads are resisted by j cable tray hanger tier, while dead load minus upward l seismic loads as well as transverse loads are resisted by clamps (Type A, G & C). i l 6.2 Longitudinal Clamps Type B, D, J, H a nd P

6. 2.1 This verification procedure requires the knowledge of l

components Pot, P, Pg and PL as defined in CPSES l y General Instructions, Sheets 24 and 24.1. Obtain IR3 absolute maximum loads (V, T ) on clamps in I a a the vertical and transverse directions, as indicated under I l 6.1.1 6 6.1. 2 and 6.1. 4 above. lR3 { 6.2.2 Obtain absolute maximum loads. La, on clamps in the Lmu;Ltudinal direction, in accordance with the Ebasco Cable Tray llanger Selsmic Design Criteria loading I combinations at the SSE level (or ODE if larger), in IR3 conjunction with Cable Tray Hanger General Instructions 1 ) Section 11 and Attachments Y & Z. j g\\ t -U Attachment Z encompasses additional longitudinal c' lamp loads attributed to the consideration of connectivity between cable tray and the transverse hangers. The consideration of connectivity is mainly attributed to ) f riction and/or binding between the tray and the transverse hanger tiers, in a straight segment of tray run, during a seismic event. Due to the relatively high resisting capacities of the longitudinal ciamps, an attempt to simplify the method-ology indicated in the Attachment Z is described below: l Calculate the additional longitudinal clamp load by summing the appropriate self-weight mass of the trans-verse hangers in the run, together with the longitudinal tray mass at the tray supporting points of the longi-tudinal hanger. The appropriate self weight portion of the transverse hangers can be conservatively considered as the cable tray hanger self-weight divided by the number of trays supported. (h U 5 1590R

In the event that the straight line interaction equations in sections l 6,1.5 and 6.2.4 cannot be satisfied, the following alternate approach, IR3 i using interaction curves, shall be followed. 1 I 6.3 Iransverse Clamps Type A, G and C I l 6.3.1 Obtain absolute maximum loads on clamps (V, T ) as a a indicated under 6.1.1, 6.1.2 and 6.1.4 lR3 1 6.3.2 For given V obtain allowable T using interaction l a s curves f rom Appendix D.

I i 8.0 SUITABIL_ITY OF_ CLAMPS SUBJECTED TO CYCLIC LOADS l In general, this specification establishes clamp allowables based on monotonic test results using recommended safety f actors as per ASME Boiler and Vessel Code. The suitability of clamps under cycling loads has been established on the basis of tests performed of Type A, C and G for transverse clamps i and on Type B, D and J for longitudinal clamps. See Appendix C. Appendix C indicates the range of cycling tests as compared with the static tests (Fig. 12 through 19). ( 8 1590R

4 ' All five (5) cycle and sixty. (60): cycle tests 'on clamps show stable results and limited deflections'for alternating test loads greater than. the established allowables shown in Appendix A and 15.- The results of e the cycling tests. shows. that higher allowables could be obtained for-k certain clamps if the need arises. 9.0 /1 TERNATE ~APPROACll lR3 . The acceptance of cable tray clamps 'shall' be based on the clamp design. evaluation procedure presented under Paragraphs 6.0 or 7.0. IR3 i for clamps with excessive loads, which cannot be qualified as indicated above, an alternate approach should be followed for clamp load determination as documented in Section V of the Cable Tray 11 anger IR3 Seismic Design Criteria.
