J SEAVER VA1,IZf SPECIFICATICK ATIACMENT NO. 6 t" J.O.No. 11700 September 25, 1966 Revised December 7 1070' Revised February 11,, 1971 q EEAVER VAL 12Y POER STATION - UNIT NO.1 SEISMIC DESIGN P2 QUIRE!ENTS j The necessity for equipment defined in this specification to withstand an Operating Basis Eartnquake and Design Basis Earthquake is a requirement prescribed by regulatory agencies having jurisdiction over this nuclear project. The vendor shall confirc: in viriting, and shall submit eight copies of calculations for Stone & Webster approval which support his j statement that the equipment furnished under this specification i meets the requirements for the Operating Basis Earthquake and Design Basis Earthquake listed belcu. The vender shall, as a part of his report, provide natural frequency data, determined i ('~ by either analysis or test. The vendor shall perform a static analysis er a dynamic analysis, i or a test to demonstrate that the equipment meets the seismic req uirements. The "g" f acters required for a static analysis I are 51ven under paragraphs 1.1 and 1.2. The guicelines under paragraph 5 should be used in prepa-lng the static analysis, i {' ' If a dynamic analysis is to be performed, the calculational ) techniques must be submitted to and approved by,the Engineers. ] For a dynamic anal tabulation of "g" ysis the En inuers will make available a c facters as a funcLion of equipment natural freq uency. If a test is to be performed, the test procedures-must be submitted to and approved by the Engineers. In a test the q "g" factors g-and gg given under paragraph 33shall be used. The guidelines unSer para, graph 6 or 7 should be used for preparing the 4 dyr.acic anglysis calculational techniques or the test procedures, respective;y. 1.1 OPERATING EASIS IARTEQUAKE i The equipment shall be designed to be capable of continued operation for 211 normd operating leads acting Simultaneously with both heri ental and vertical Operating Basis esismic loading. The horizontal and vertical seismic Icadings, respectively, are: (Herizontal) 51= 4A g g2 " J.i g (Vertical) The horizontal and vertical seismic 1 cads shall be added directly considering a single hori: ental directicu earthquake to act opneurrently with the ( vertical direction earthquake. ~

If no codes are used, the stress ' levels under the aheve ( sibined 10adir:g' shall not exceed 90 per-cent of.he minimum yield strength per the ASTM specification for.the materitiv. 1.2 DESIGN BASIS EARTHQUAKE The equipment shall be designed to withstand the c0=bined. effects cf all ncrmal cperating 1 cads acting simultaneously with Design Basis seismic loads without loss of function or structural integrity. The horizontal ~ and vertical seismic loadings, respectively, are : ( E= o.2 g+ (Horizontal) 3 54" 43 C' (Vertical) The horizontal and vertical seismic loads shall be added directly considering a single horizontal (~, direction earthquake to act concurrently with the vertical direction earthquake.

l l 3 /'1 J ( 5. GUIDELINES FOR STATIC ANALYSIS The vender is required to multiply the appropriate l masses of the equipment components by the acceleration l values in three orthogonal directions, so as to load I the equipment in these directions. One direction of horizontal earthquake shall be considered concurrently with the vertical direction earthquake. The structural load-carrying members, whether j internal compenents or external components such as held-down bolts, must be checked to ensure adequacy of design under seismic loading. l 6. GUIDELINES FOR DYNAldC AN ALYSIS l l The first step in a dynamic analysis is to formulate { a suitable mathematical model which represents 1 ( adequately the behavior of the equipment. Although I

a. simple set of instructions for the dynamic analysis of equipment items would not be generally applicaole, sc=e of the step-by-step consideratacns which might be used to define an ac:eptable modal are as follows:

l a. The areas of the equipment which might be critical Should be identified, l 1 1 ( \\ b. Assumptions necessary to Eenerate a tractable model. c. An examination of the we1 hts and significanas 5 of various equ$ pment components, d. The extent to which the propcsed mass breakdown permits determination of stresces or deflections ) in the previously defined critical areac, e. The characteristics of the supports and/or attachments to be included in the model. f. The properties cf eennecting members between masses necessary to approximate the structural stiffness cf the system. g. The decision to include an element of the equip-ment as a separate mass peint may depend on the natural frequency of the element. Estimates of l the natural frequencies Of the elements which are large enough to affect tae response of the system should be determined pricr to lumping the element stiffness and muss. s e wy ee 4 4e eh m esumeme e

i "I 4 Once the mathematical model for the equipment is established, natural frequencies, mode shapes, and participation factors can be readily ecleulated. The amplified response, spectrum fer the appropriate J equipment damping level and elevation of the suppert is used as input to calculate the seismic accelerttiens at the mass points identified in the model. The seismic equivalent static forces are obtained by multiplying the lumped masses of the model by the calculated seismic accelerations. With the determination ef'the equivalent static forces, member stresses are determined in a manner similar to that used for static analysis. 7. GLTDELINES FOR VIERATION TESTING / It is difficult to cover all the testing possibilities cr procedures whdcl msy be appropriate fer qualifying equipment by vibration te. sting. The vendor is enecuraged i to propese test precedures or existing data which I comply with the specification requirements fer review and approval, {;. The following items are minimum requirements : a. The equipment sho]1 he tected while either 1. Functionira: 2. Not functioning 3. Both The specificatlen snou.16 indicate which one of the conditions, a., b., er c., is applicable s and the vibration tests shoule comply,- ) b. The equipment should be mounted as closely as possible to the -in-service orientation in a machine of suitable capacity, c. A frequency scan (J eandard logarithmic sweep) at a constant neccleration of "c" shall be performed fer as much of the range between 2 and 200 cycles per seccnd as practicable. The objective of this test is to dete.9eine the natural frequencies and amplification facters cf the tested equipment and its critical ecmpenents er appurtenances. The acceleration constants to be ucer would be cq and gh,. given under paragraph 3 of this attacnm:nt-The horicental directicn "e" ( value sna11 be a;; lied in two perpendicular Exes criant ed to evnsiaer equipment crientaticn and d

1 ,5 = 5 L worst case results. Alternatives to sine wave forcing, such as " sine beat" or random excitation, nay also be considered. 1 d. A " Dwell Test" of the component. This would include as a Winimum, a test of from 1 to 15 minutes duraticn at the frequency and input for which the maximum component response was noted in (3). Additionally (a)ther frequencies would be o selected if they are deemed severe - amplification facter equal or Ereater than 2.0, and (b) the frequency of the response is sufficiently removed from the major peak. such that it can be regarded as discrete, j 1.e., the new frequency falls outside of the band of +50 percent of the old frequency. I 8. NCZZLE LOAOS FOR " COUPLED" COMP 0NENTS The paragraph below sha11/sman.===rw apply. The vendor shall provide the allowable loads a-the no::les of the equipment. The alicwable loads shall be these that cause stresses greate" than the allowable stresses in the no :le or in the equipment itself. In stress analyzing the equipment, the no::le loads must be combined with the seismic and operating 1 cads. The contribution to the stress in the equipment by nor:le loads shall be maximized by assuming the worst combination of single loads acting at each no::le, simultaneously. For example, the stress at a point may be maximized by 1 considering the seismic load (at the center of gravity i of the component ) plus a moment at one no::le, a radial x ) load en a second, and so forth, until all no::les are included. The no :le design forces may be determined by the method given in tne Welding Research Council Su11stin 107 " Local Stresses in Spherical and Cylindrical Shells Due to External Leadings," by K. R. Wichman, A. G. Hopper, and J. L. Mershon, dated August,1965, revised Leeember, 1968. Other methods are also acceptaole, provided they are approved by the Engineers.
