1971 SEAVER VALLEY POWER STATION - UNIT NO.1 SEISMIC DESIGN REQUIREMENTS The necessity for equipment defined in this specification to withstand an Operatirs Basis Earthquake and Design Basis Earthquake is a requirement prescribed by regulatory agencies having jurisdiction over this nuclear prcject.

The vendor shall ccnfim, in writing, and shall submit eight ecpies of calculations fer Stone & Webster approval which. support his statement that the equipment furnished under this specification meets the requirements for the Operating Basis Earthquake and Design Basis Earthquake listed belcw.

The vendor shall, as a part of his report, prcvide natural frequency data, determined

(

by either analysis or test.

The vender shall perfom a static analysis or a dynamic analysis, or a test to demonstrate that the equipment meets the seismic requirements.

The "g" factors required for a static analysis are given under paragraphs 1.1 and 1.2.

The guidelines under paragraph 5 should be used in preparing the static analysis.

., J If a dynamic analysis is to be perfor,med, the calculational techniques must be submitted to and approved by the Engineers.

(~

For a dynamic anal tabulation of "g" ysis the Engineers will make available a factors as a function of equipment natural frequency.

If a test is to be performed, the test procedures must be submitted to and approved by che Engineers.

In a test the "g" factors s and 54 given under paragraph 3,shall be used. The guidelines unher paragraph 6 or 7 should be used for preparing the dynsmic anglysis calculational techniques er the test procedures, respective _y.

s I

1.1 OPERATING BASIS EARTHRUAKE The equipment shall be designed to be capable of continued cperation fer all normel operating loads actirs simul cneously with both horizontal and vertical Operating Basis seismic loading.

The l

horizontal and vertical seismic loadings, respectively, are:

l (Horizontal) gy= 4.6 g (Yertical) g2 " 2*1 F i

'The horizontal and vertical seismic loads shall

be added directly considering a single hori: ental direction eartnquake to act opncurrently with the 1

above conbined icading shall not exceed CO per-cent of the minimum yield strength per the ASTM i

spscificatien for_the =ater1 G.'.

i 1.2 DESIGH 3 ASIS EARTHQUAKg

GUIDELINES FOR STATIC ANALYSIS The vender is required to multiply the appropriate masses of the equipment ecmponents by the acceleration values in three orthcgenal directions, so as to lead the equipment in these directicns.

One direction of herincntal earthquake shall be considered concurrently with the vertical direction earthquake.

The structural lead-carrying members, whether internal components er external ccaponents such as hold-dcun belts, must be checked to ensure adequacy of design under seismic leading.

6.

GUIDELINES FOR DYNAMIC AN ALYSIS j

The first step in a dynamic analysis is to formulate a suitable mathematical model which represents adequately the behavior of the equipment.

Although a simple set of instructions fcr the dynamic analysis of equipment items wculd not Le generally applicable, l

some of the step-by-step considerations which might be used to define an acceptable model are as fcilows :

i The areas of the equipment which might be critical a.

should be identified.

GEDELn!ES FOR DYMAMIC ANALYSIS The first step in a dynamic analysis is to fc=mulate a suitable mathematical model which represents j

e adequately the behavior of the equipment.

Although a simple set of instructions for the dynamic analysis l

j of equipment items would not be generally applicabic, some of the step-by-step considerations which might I

be used te define un acceptcble model are as follows :

The areas of the equipment which might be critical a.

should be identified.

(

b.

Assumptions necessary to generate a tractable

model, l

i An examination of the weights and significance c.

of varicus equipment components.

j i

l d.

The extent to which the prepcsed mass breakdown permits determination of stresses or deflections

}

in the previously defined critical areas.

L The characteristics of the supports mad /or e.

l l

attachments to be included in the mcdel, f.

The prcperties of connecting members between masses necessary to approximate the structural stiffness of the system.

The decision to include an element of the equip-g.

ment as a separate mass point may depend en the natural frequency of the element.

Estimates of the natural frequencies of the elements which are large enough to affect the response of the system should be determined pricr to lumping the element stiffness and muss, s

'c 1

Once the mathematical model for the equipment is established, natural frequencies, mede shapes, and participation factors can ce readily calculated.

The amplified respense spectrum for the appropriate equipment dampin; level and elevation cf the suppcrt is used as input tc calwulate the seismic accelerations at the mass points identified in the' medel.

The I

seismic equivalent static forces are obtained by multiplying the Icnped masses of the mcdel by the calculated seismic accelerations.

With'the determination of the ecui"s. lent static forces, member stresses are determined in a manner similar to that used for static analys;s.
