Dear Mr. Youngblood:

Enclosed are the following documents relative to the Susquehanna SteamElectric Station Seismic-Hydrodynamic Program for Qualification of Safety-Related equipment. These documents were requested by your Mr. Arnold Leein support of the Seismic Qualification Review Team Site audit now scheduledfor the week of March 16 through 20, 1981.

1) The GE NSSS response to NRC FSAR Question 123.1, .3, .4, .5, .6,.7, and .9.

2) The previous response to NRC FSAR Question 110.42 concerning loadcombinations for the NSSS qualification of equipment. Refer to ourletter to NRC PLA-536.

3) Part of previous transmittal of slides from PPItrL-NRC SQRT meetingof December 18, 1980. Refer to our letter to NRC PLA-602, January 2,1981.

4) Bechtel Specification 8856-G-22, Revision 4, "General ProjectRequirements for Design Assessment and Qualification of SeismicCategory I Equipment and Equipment Supports for Seismic and HydrodynamicLoads for Susquehanna Steam Electric Station Units 1 and 2."

.5) A summary of our 3/4/81 telephone conversation with Dr. Lee.

By separate transmittals, we have, on February 26 and 27 delivered the I/Jfollowing PROPRIETARY documents to your Mr, Richard Stark and Mr. Morris Reich(BNL):

Pursuant to Genera) Design Criterion 2. safety-re'fated structures,systems and components are to be designed for appropriate load combina-.tions arising from accidents and severe natural phenomena- V)th regard,& the vibratory loads attr)but% to the feedback of hydrodynamic loadsfrom the pressure suppression pool ot the containment, the staff requiresthat safety-related mechanical, electrical, instrumentation and.controlequipment be designed and qua'fified to withstand effects ot hydrodynamic

. vibratory loads associated with ither safety relief valve (SRV) dischargeor LOCA blmdo~a into the pressure suppression containment combined ariththe effects of dynamic )oads arising from earthquakes.

'hk. cr)tera to be used by the staff to determine the ncceptabi)ity ofyour equipment qualification program for seismic and dynamic 'toads areIKEE Std. 344.-f975 as supplemented by Regulatory Guides X.XQQ and 1.92,

7.1 Methods and Procedures

. The dynamic analysis of various equiprent can beclassified inta three cases according to the rela-tive rigidity of the equipaent based on the mag-nitude of first natural frequency as below.

(a) Structurally simple equipnent —that equip-ment which can be adequately representedby one degree of freedan system.

(b3 Structurally rigid equipnent - thaC equip-aent whose fundanental frequency is:...

(i) greater than 33 Hz for theconside-'ationof seismic loads.

(ii) greater than SO Hz for the conside-ration of hydrodynamic loads.

(c) Structurally Ccmplex equ'~nt - are +~sewhich cannot be classified as structurallysimple or structurally. rigid.

When the equipmnt is structurally s&pleor rigid in one direction but ccmolex inthe other, each direction may be classifiedseparately to determine the dynamic loads.

711 Res nse ctrum Anal sis

The appropriate response spectra for speci-fic equipnent are, issued with the equipaentspecification for OBE, SSE; and hydrodynaad.cloads. Response spectra are based upon thdynamic analyses of the supporting structure-and represent th dynamic response of a singledegree of freedcm system at a particularlocation within the structure. Response spectraplotted in terms of acceleration versus frequency,correspond to various locations within tbbuildizgs and are identified with respectto the points noted on 0he mathanatical'adelfor each direction of vibration to be considered.~s may include the vertical as wel1 as boththe N-S ard E-'N horizontal directions. Znaddition, each response spectrum correspondsto a particular damping ratio, i.e., theratio of damping af the single degree of freedomsystem to critical damping.

Ghe horizontal seIsmic response spectra pro-vided have been generated with respect to amaximum horizontal ground acceleration of0.05g corresponding to the OBE, and a maxi-mum ?urizontal ground acceleration of 0.10gcorrespo~ to the SSE unless otherwisenoted. 5he vertical response spectra arebased on ground accelerations which are 2/3of the horizontal accelerations.

LOAD COMBINATIONS:

These were transmitted to the NRC on 8/28/80 as Page 3 ofAttachment N to PLA-536. This was in response to NRC Question110.42, and the entire response will be telecopied to Arnold Lee.

IMPLEMENTATION OF LOAD COMBINATIONS:

The GE SQRT Program uses outputs from the GE EquipmentAdequacy Evaluation Program which combines dynamic loads bySRSS as accepted by the NRC in NUREG-0484.

The individual items associated with the load combinationsare added as described below:

Steady State Events (e,g,, Dead Load, Pressure) - Absolute Sum

Time Varying Components (e.g., Maximum Seismic, Maximum Hydro-dynamic) — SRSS

Components of Events (e.g., Maximum X-Load Due to Y-Earthquake) — SRSS

Modal Response-SRSS, except for closely spaced modes where effectsare combined by Absolute Sum, Double Sum, or Grouping.

Details for each item of equipment are contained in thatequipment's Design Record File which is available for audit.
