If the plant is founded on rock or a very stiff soil site without controlled, compacted backfill, then the"effective grade" is the elevation where the structure receives significant lateral support from the surrounding soil or rock (e.g., the top of the base mat). Similarly, "effective grade" should be taken at the foundation level if crushable foam insulation or other measures are used to isolate the structure from the lateral support of the surrounding soil or rock. If an internal structure of the building is supported primarily at the base mat without significant lateral support from the surrounding structure, then the"effective grade" is the elevation at the top of the base mat.Based on the above definition, a sketch (see next page) has been prepared showing elevations of building at top of base mat or at foundation level and elevations of significant lateral support (i.e. top of compacted earth fill on the perimeter of the buildings).

Effective Grade calculated is based on those elevations.

CALCULATION OF BASIC PARAMETERS FOR A46 AND SHEET 11 OF__INDIVIDUAL PLANT EXAMINATION OF EXTERNAL EVENTS BFN UNIT 0 (IPEEE) SEISMIC PROGRAM CD-Q0000-940339 PREP DATE CHKD J DATE r 6.2 COMPARING EQUIPMENT SEISMIC CAPACITY TO SEISMIC DEMAND Seismic adequacy of an item of mechanical or electrical equipment can be verified by demonstrating that the seismic capacity of the equipment is greater than or equal to seismic demand imposed on it. The seismic capacity of equipment can be represented by a "Bounding Spectrum" based on earthquake experience data, or a "Generic Equipment Ruggedness Spectrum" (GER'i) based on generic seismic test data. These two methods of representing seismic capacity of equipment can only be used if the equipment meets the intent of the caveats for its equipment class.The seismic capacity of an item of equipment can be compared to a seismic demand which is defined in terms of either a ground response spectrum or an in-structure response spectrum.There are two methods (Method A and B) for comparing capacity versus demand.Method A is for making a comparison with a SSE Ground Response Spectra. Method A can be used i) when equipment is mounted below about 40 feet above the effective grade which has already been determined and ii) Equipment has natural frequency greater than about 8 HZ. Method B is for comparison with an in-structure response spectrum.

Method B can be used for equipment which is mounted at any elevation of plant and/or for equipment with any natural frequency.

To verify seismic adequacy, in general, the seismic capacity spectrum should envelop the seismic demand spectrum at all frequencies with two special exceptions:

  • The seismic capacity spectrum needs only to envelop the seismic demand spectrum for frequencies at and above the conservatively estimated lowest natural frequency of the item of equipment being evaluated.
  • Narrow peaks in the seismic demand response spectrum may exceed the seismic capacity response spectrum if the average ratio of the demand spectrum to the capacity spectrum does not exceed unity when computed over a frequency range of 10% of the peak frequency (e.g., 0.8 HZ range at 8 HZ).So for comparison purposes the following methods are to be followed for BFN A46 evaluations:

Method A: ITEM / FIGURE NO.

Response Spectrum From the data given in GIP (Reference 3.1) Capacity based on Bounding Spectrum and GERS has been plotted against the Browns Ferry SSE Ground Response Spectrum ( Figure 2.5 Reference 3.4) and In-Structure Response Spectrum (Reference 3.3) in Figures A.1, A.2, A.2A, B.1, B1.1, B.3, B.3.1, B.3A & B.3A.1. All plots have been made for 5% damping and envelope of North-South and East-West data.Following observations are made from plots of Figures for capacity versus demand: Figure A.1: Figure A.2: Figure A.2A: Figure B.1: Bounding Spectrum always envelops SSE Ground Response Spectrum.So capacity is greater than demand for equipment located within about 40'from effective grade and has fundamental frequency above about 8hz.GERS for given mechanical equipment envelops 1.5 X 1.5 X SSE Ground Response Spectrum.

So capacity for given equipment are greater than demand provided caveats are met.GERS for given electrical equipment envelops 1.5 X 1.5 X SSE Ground Response Spectrum.

So capacity for given equipment are greater than demand provided caveats are met.This figure is for Reactor Building (outside Drywell) only. 1.5 Times Bounding Spectrum envelops in-structure response at elevation 565 and 519. For elevation 593, peak in-structure response is slightly higher than the 1.5 X Bounding Spectrum curve and it does not meet the exception rule for narrow band exceedences discussed above (i.e., average ratio of in-structure response to 1.5 times Bounding Spectrum is less than unity)So seismic demands for equipment located at Reactor Building floor elevation 565 and below is less than the capacity based on Bounding Spectrum, but equipment located at Reactor Building above elevation 565 is not enveloped by the 1.5 times Bounding spectrum curve.Figure B.1.1 This figure is for Diesel Generator (DG) Buildings and Intake Pumping Station (IPS) structure only. 1.5 Times Bounding Spectrum curve does not envelope in-structure response of DG building and IPS structure.

GERS for the given mechanical equipment always envelops 1.5 times SSE in-structure response spectrum.

So seismic capacity of equipment based on GERS is always greater than seismic demand provided all the caveats are met.This figure is for Diesel Generator Building and Intake Pumping Station.(IPS) structure only. GERS for the given mechanical equipment always envelops 1.5 times SSE in-structure response spectrum.

So seismic capacity of equipment based on GERS is always greater than seismic demand provided all the caveats are met.This figure is for Reactor Buildling (outside Drywell) only. GERS for the given electrical equipment does not always envelops 1.5 times SSE in-structure response spectrum.

So it is required to be determined on a case by case basis whether seismic capacity of equipment based on GERS is greater than seismic demand provided all the caveats are met.1: This figure is for Diesel Generator Building only. GERS for the given electrical equipment does not always envelops 1.5 times SSE in-structure response spectrum.

So it is required to be determined on a case by case basis whether seismic capacity of equipment based on GERS is greater than seismic demand provided all the caveats are met. There are no electrical equipment located in IPS structure which is on SSEL.In Table 1, attempt has been made to determine basis for seismic capacity and demand for Mechanical equipment contained in the SSEL for BFN units 2 & 3. Similarly, Table 2 has been generated for Electrical equipment contained in the SSEL for BFN units 2 & 3. Note that there are no equipment classes 5 (Horizontal Pumps), 1 1 (Chillers), 12 (Air Compressors) and 19 (Temperature Sensors) in BFN SSEL.

6.3.2 CALCULATION

OF SEISMIC MARGIN EARTHQUAKE Browns Ferry is a 0.3 g focused plant as far as IPEEE seismic evaluation is concerned.

Amplification factor is calculated based on comparison between BFNP Ground Response (based on 0.2g Housner) to 0.3g Review Level Earthquake (RLE) Ground response based on NUREG CR-0098 median spectral shape.For Rock site: Ground Acceleration(A)

= 0.3g Ground Velocity(V)

= 2.12 Velocity = 1.65 Displacement

= 1.39 So, amplified displacement

= 10.74 x 1.39 = 14.93 in amplified velocity = 14.4 x 1.65 = 23.76 in/sec amplified acceleration

= 0.3 x 2.12 = 0.636g (say 0.64g)Table 5 and Figure C.1 show the response spectra plot from which amplification factor is determined for rock foundation.

Maximum acceleration due to 0.3g = 0.64g Corresponding acceleration due to ground response @ 8.333 Hz frequency

The scale factor will be defined as the ratio of SME acceleration over SSE acceleration at the frequency of interest, i.e. the dominant fundamental building response frequency.

Scale Factor = g SME (Odominant frequency)

/ g SSE (1@dominant frequency)

Prior to applying the scale factor, the SME in-structure will be reduced to account for a higher level of structural damping (7%) than that used in the existing building analysis t (5%/6). 7% damping is based on review of existing stress level in the structure (some element stresses are at more than 50% level).Reduction Factor = [(5%) / (7%)] 1/2 = 0.85 Based on review of in-structure response spectra (Reference 3.3) the dominant fundamental frequencies for each buildings are: Reactor-building (outside Drywell) -6 Hz (N-S & E-W)Diesel Generator Building -12 Hz (N-S & E-W)Intake Pumping Station -16 Hz (N-S & E-W)The above values are based on the peaks of all the floor response spectra for each building.

To account for the possibility that 12-16 Hz may be soil modes instead of building modes, conservatively use the worst case ratio of SME/SSE i.e. at 8.33 Hz.6.3.4 COMBINED SCALE FACTOR FOR IPEEE Combined scale factor is calculated by multiplying scale factor to reduction factor.* Reactor Building:

0.85 x (0.64 / 0.29) = 1.88* Diesel Generator Building:

0.85 x (0.64 / 0.25) = 2.18* Intake Pumping Station: 0.85 x (0.64 4 0.25) = 2.18 In-structure floor spectra should be scaled upward by these factors to define IPEEE demand at a 0.3g (50% NEP) level for a NUIREG CR-0098 spectral shape.

SUMMARY

OF RESULTS AND CONCLUSION General observations can be summarized as follows: 1. Diesel Generator buildings and Inlake Pumping Structures are within 40 feet from effective grade elevation.

2. Reactor building up to El. 593' is within about 40 feet from the effective grade elevation.
3. Bounding spectrum envelopes both the SSE (A46) & SME (IPEEE) Ground response spectrum, i.e., for equipment located at or below 40 feet from effective grade elevation and having a frequency

> 8 Hz, capacity exceeds demand for both A46 and IPEEE.4.
