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 loads from the pressure suppression pool ot the containment, the staff requires that safety-related mechanical, electrical, instrumentation and.control equipment be designed and qua'fified to withstand effects ot hydrodynamic
. vibratory loads associated with ither safety relief valve (SRV) discharge or LOCA blmdo~a into the pressure suppression containment combined arith the effects of dynamic )oads arising from earthquakes.
'hk. cr)tera to be used by the staff to determine the ncceptabi)ity of your equipment qualification program for seismic and dynamic 'toads are IKEE Std. 344.-f975 as supplemented by Regulatory Guides X.XQQ and 1.92,
. and Standard Review P)an Sections 3.9.2 and 3.30. State the extent to
'which the equipment. in your plant amets these requirements and the above requirements to ccebine sexism)c ancf hydroxy'naeic vibratory loads. For
. equipment that does not ace'C. these requirements provide )ustification for the use of other criteria.

(a) Structurally simple equipnent that equip-ment which can be adequately represented by one degree of freedan system.
(b3 Structurally rigid equipnent - thaC equip-aent whose fundanental frequency is:...
(i) greater than 33 Hz for the of seismic loads.

When the equipmnt is structurally s&ple or rigid in one direction but ccmolex in the other, each direction may be classified separately to determine the dynamic loads.
711 Res nse ctrum Anal sis The appropriate response spectra for speci-fic equipnent are, issued with the equipaent specification for OBE, SSE; and hydrodynaad.c loads. Response spectra are based upon th dynamic analyses of the supporting structure-and represent th dynamic response of a single degree of freedcm system at a particular location within the structure. Response spectra plotted in terms of acceleration versus frequency, correspond to various locations within tb buildizgs and are identified with respect to the points noted on 0he mathanatical'adel for each direction of vibration to be considered.
~s may include the vertical as wel1 as both the N-S ard E-'N horizontal directions. Zn addition, each response spectrum corresponds to a particular damping ratio, i.e., the ratio of damping af the single degree of freedom system to critical damping.

eu i LOAD COMBINATIONS:
These were transmitted to the NRC on 8/28/80 as Page 3 of Attachment N to PLA-536. This was in response to NRC Question 110.42, and the entire response will be telecopied to Arnold Lee.
IMPLEMENTATION OF LOAD COMBINATIONS:
The GE SQRT Program uses outputs from the GE Equipment Adequacy Evaluation Program which combines dynamic loads by SRSS as accepted by the NRC in NUREG-0484.
The individual items associated with the load combinations are 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 effects are combined by Absolute Sum, Double Sum, or Grouping.
Details for each item of equipment are contained in that equipment's Design Record File which is available for audit.
