STEVENSON & ASSOCfATES USl A 46 / IPEEE, Equipment By: A. Karavoussianis Fragilities for HX-98 and HX-99 cons ing e g neer n fm Check: T. M. Tseng Objective The objective of this calculation is a document a fragility for the Residual Heat Removal Pump Area Cooling Coil (HX-98) and the Containment Spray Pump Area Cooling Coil (HX-99) and evaluate the adequacy of their vibration iso!ators. Vibration isolators are not outliers for A-46 evaluations, but their capacity to resist load needs to be evaluated.

Analytical Approach The load path of the Cooling Coil's supporting structure will be evaluated in order to determine its critical point. The critical point anchorage will be subject to the seismic input of the IPEEE floor response spectra, which has a reference peak ground acceleration (PGA) of 0.4 G.

Finally, the equipment HCLPF will be extracted by multiplying the anchorage's factor of safety by the referenced PGA snd the fragility by multiplying the HCLPF by 2.1.

The adequacy of the vibration isolators for an A-46 evaluation will be investigated by comparing the IPEEE input spectra to the design basis earthquake (DBE) spectra, which is used for A-46 evaluation.

Summary The belt tightness checking procedure discovered that one of the vibration isolators supporting W-67 (HX-98) is not anchored into the concrete floor (ref.10). Also, the W-67 is a smaller unit with different isolators (i.e. smaller in size) (ref. 9). Hence, the capacities of HX-98 and HX-99 will be separately calculated (i.e. not enveloped).

For HX-99, the calculation computed a HCLPF of 0.56 G and a fragility of 1.18 G, which are limited by the capacity of the vibration isolators. Also, the calculation showed that an A-46 evaluation of the fan's vibration isolators and anchorage will yield a minimum safety factor of at least 1.08 > 1.0, hence, HX-99 Is adequate in terms of an A-46 evaluation.

For HX-98, the calculation computed a HCLPF of 0.28 G and a fragility of 0.59 G, which again are limited by the capacity of the vibration isolators. Also, the calculation showed that an A-46 evaluation of the fan's vibration isolators and anchorage will yield a minimum safety factor of about 0.53 < 1.0, hence, HX-98 is an i 46 out:ier.

a structural-mechanical Fragilities for HX-98 and HX-99 consulting engineering firm Check: T M Tsen9 Calculation HX-98 and HX-99 are cooling coils which serve the Emergency Cooling Fans W-67 and W-68 respectively. The cooling coils (HXs) are bolted to two opposite walls of the fan's housing by 24

- 1/2' bolts per wall. The fan housing rests on two 4 inch channels, which span across the width of the housing. The channels are mounted on four rubber isolator, which are in a 50" x 120" pattem for W-68 (ref. 6) and a 37.75' x 62.5" pattem for W-67 (ref. 9). The channel is bolted to each isolator by a 3/8" bolt and each isolator is anchored into a 4" high concrete pad l

by 2 - 3/8" expansion anchors.

(ref. 6)

Evaluation of W-68 (HX-99h t

The vibration isolators for W-68 are Korfund Type F with a maximum load capacity of 1120 lbs i

(ref. 2 & 4). The units have approximate weights of 3100 lbs, this weight was used in ordering the isolators (ref. 3). Also, the center of gravity is assumed to be at the center of the fan casing and is estimate at 48" above the concrete pad by the Seismic Review Team (SRT) (ref. 6).

4 v

The bolt tightness check found all of the expansion anchor tight and that they are of a Phillips shell type.

(ref.10)

Load Path Analysis:

By inspection, the cooling coil (HX-99) is well supported on the fan housing and will not govem the load path or the HCLPF.

The vibration isolators, Korfund Type F, Model No. FCC-1120, have a maximum load capacity of 1120 lbs (ref. 4).

Capacity of a 3/8" bolt: (equal to a cast in place anchor with no reduction factors)

P,n = 3.74 kip & V.a = 1.87 kip (ref. 5). The capacity of the 3/8" bolt which connects the isolator to the channel is greater than the capacity of the isolator, therefore, this bolt does not govem the load path.

Capacity of a 3/8" expansion anchor:

(ref. 5) d Reduction for Phillips shell anchor. RT, = RT = 1.0 (ref.10)

Reduction for concrete strength:

RF, = 3000 / 4000 = 0.75 (ref. 8)

RF, = (3000 /10000) + 0.65 = 0.95 Pan = 1.46 x 1.0 x 0.75 = 1.10 kip & V,a = 1.42 x 1.0 x 0.95 = 1.35 kip p

Two expansion anchors per isolator P,n = 2 x 1.10 = 2.20 kip & V,n = 2 x 1.35 = 2.70 V

kip, therefore, the expansion anchors do not govem the load path.

The SRT estimated the frequency of the fan to be less than 8 Hz (ref. 6). The peak spectral acceleration of the IPEEE spectra (reference PGA c'O.4G)is at 8.5 Hz. Therefore, use the 5%

damped IPEEE peak spectral acceleration for the Cen'.ral Auxiliary Building at elevation 8'-0".

A-46 Evaluation of Anchoraae and Vibration isolators for W-68 (HX-99h The DBE peak floor response spectral accelerations for the Central Auxiliary building at elevation 8'-0* occur at a frequency of about 2 Hz. Hence, it is conservative to use these acceleration:

nose = 0.70 G (DBE peak horizontal acceleration)

(ref. 7) alPEEE = 0.54 G (IPEEE peak horizontal acceleration)

(page 5 & ref. 6)

Therefore, the minimum A-46 safety factor is calculated by multiplying the vibration isolator j

safety factor (goveming) by aipses and then dividing by aose.

Minimum A-46 Safety Factor = 1.39 x 0.54 / 0.70 = 1.08 > 1.0, therefore, HX-99 is adequate in terms of an A-46 evaluation.

I G Evaluation of W-67 (HX-98h The vibration isolators for W-67 are Korfund Type FB or FBB (ref. 9). In estimating the unit's weight and possible isolator type the size of the heat changers in each unit will be compared, because they make up most of the unit's weight.

(ref. 9 & 11) 3 Size of HX-99 = 126 x 38 x 15 = 71800 in & Size of HX-98 = 64 x 33 x 15 = 31700 in Estimated weight of W-67 = 3100 x (31700 / 71800) = 1370 lbs, Hence, estimated weight per vibration isolator for W-67 = 1370 / 4 = 340 lbs.

Therefore, consider the Korfund Type FB or FBB, Color Code Red, vibration isolator which have a maximum load capacity of 470 lbs and a maximum weight of 4 x 470 = 1880 lbs for l

W-67.

According to the As Built Sketch of W-67 the center of gravity is located about 23 - 1.375 =

21.625' between the isolator distance of 37.75' (i.e. the isolator centroidal axis is at a distance of 37.75 / 2 = 18.875'). Since, the center of gravity for W-67 is estimated, it is close enough to i

the isolator's centroidal axis to consider the C.G. at the centroidal axis. Also, the astimated height of the center of gravity is at 30 + 3.5 + 1 = 34.5" vef.9) l The spectral accelerations are the same as for W-68 (HX-99).

Karavoussianis a structural-mechanical Fragilities for HX-98 and HX-99 Check: T. M. Tseng consulting engineering firm Vibration isolator Caoacity in Shear and Tension:

Since, the vibration isolators are made of rubber, this calculation will verify their required shear and tensile capacities. Although, the Korfund isolator data is not available, these series F isolator are similar to the type N Mason isolator, for which data is available. Therefore, assume that the Korfund and Mason isolators will have similar properties.

(ref. 4 & 12)

According to the Mason data, the vibration isolator are loaded in both shear and compression to provide the straight line Load Deflection curves (ref.12). Since, the calculation adds the axial and shear loads arithmetically (not as vectors), the combination of axial and shear will not exceed the allowable load and the calculation's load combination concurs with the Mason data.

Also, according to the Mason catalog, the ultimate tensile capacity of this type of isolator ranges from 2000 psi to 2500 psi (ref.12). This means that the Korfund isolators for W-67 (HX-98) may have an ultimate tensile capacity of about 2 x 2 x2000 = 8000 lbs (ref; 4, series FB or F88). Since, shear makes up about 50% of the load on the isolator and the allowable load is 460 lbs, the tension load is about 230 lbs. Hence, the tensile load is about 3% of the ultimate tensile capacity and is judged acceptable.

The ultimate tensile capacity of the Korfund isolators for W-68 (HX-99) is about 3 x 3 x2000 =

18000 lbs (ref. 4, series FCC). Since, shear makes up about 50% of the load on the isolator and the allowable load is 1120 lbs, the tension load is about 560 lbs. Hence, here too, the tensile load is about 3% of the ultimate tensile capacity and is judged acceptable.

It is possible to load these vibration isolators in shear and to consider the compression allowable as a tensile allowable, because the tensile loads computed in this calculation have little if any effect on the isolators.

COMMENTS The SRTs are R. P. Kennedy and A. R. Bayer - 10/25/93.

l REF: Bechtel Dwg. C-103 Rev. 4 & C-196 Rev. 5 and S&A Calc. No. 91C2696-C-0,16 Titled "USl A-46 /

l A IPEEE, Equipment Fragilities for 1 A-05,1 A-06,2A-05 and 2A-06" Capacity:

BSCav.3: The SRT was not able to see the potential transformer. However, a review of the pictures in the component instruction manual showed the transformers on the sides and not an issue.

BSCav.4: Switchgears 1 A-05 and 1 A-06 are adjacent to each other and consist of a total of 10 bays interconnected.

Anchorage:

The bays, Westinghouse type, are anchored by 2 rows of plug welds to embedded steel (see attached field sketch). Each bay is 26" wide x 79" deep x 90" tall. Since the overall depth is 79", there is no plausible of the switchgear overturning due to DBE and the embedded channel's shear caoacity is judged adequate (see S&A Calc.).

For the anchorage analysis conservatively consider the first 3 bays, for which the first bay is unanchored. Also, consider each bay weighs 3300 lbs and the plug welds' equivalent 1/8" fillet lengths are as computed in the referenced S&A calculation (see attached excerpts).

The anchorage analysis yields a safety factor of 2.256 for the welds and the referenced S&A calculation computed the a safety factor of 1.69 for the embedded steel, hence the switchgears' anchorage safety factor is 1.69.

ynn COMMENTS The SRTs are R. P. Kennedy and A. R. Bayer - 10/25/93.

REF: Bechtel Dwg. C-103 Rev. 4 & C-196 Rev. 5 and S&A Calc. No. 91C2696-C-016 Titled "USl A-46 /

O IPEEE, Equipment Fragilities for 1 A-05,1 A-06,2A-05 and 2A-06" V

Capacity.

BSCav.3: The SRT was not able to see the potential transformer. However, a review of the pictures in the component instruction manual showed the transformers on the sides and not an issue.

BSCav 4: Switchgears 2A-05 and 2A-06 are adjacent to each other and consist of a total of 10 bays interconnected.

Anchorage:

The bays, Westinghouse type, are anchored by 2 rows of welds to embedded steel. The welding is a combination

'of pulg welds, fillet welds all around and half way around the holes (see attached field sketch). Each bay is 26" wide x 79" deep x 90" tall. Since the overall depth is 79", there is no plausible of the switchgear overturning due to DBE and the embedded channel's shear capacity is judged adequate (see S&A Calc.).

For the anchorage analysis conservatively use 1/8" fillets around the holes and consider 3 bays, in which two of the bay have fillets and the last bay is pulg welded. Also, consider each bay weighs 3300 lbs and the plug welds' l

equivalent 1/8" fillet lengths are as computed in the referenced S&A calculation (see 1 A-05 for calculation 4

excerpts).

The anchorage analysis yields a safety factor of 4.603 for the welds and the referenced S&A calculation computed the a safety factor of 1.69 for the embedded steel, hence the switchgears' anchorage safety factor is 1.69.

Ygg COMMENTS The SRTs are R. P. Kennedy and A. R. Bayer - 10/25/93.

REF: Bechtel Dwg. C-103 Rev. 4 & C-196 Rev. 5 and S&A Calc. No. 91C2696-C-016 Titled "USI A-46 /

'i IPEEE, Equipment Fragilities for 1 A-05,1 A-06,2A-05 and 2A-06" Capacity:

BSCav.3: The SRT was not able to see the potential transformer. However, a review of the pictures in the component instruction manual showed the transformers on the sides and not an issue.

BSCav.4: Switchgears 1 A-05 and 1 A-06 are adjacent to each other and consist of a total of 10 bays interconnected.

Anchorage:

The bays, Westinghouse type, are anchored by 2 rows of plug welds to embedded steel (see attached field sketch). Each bay is 26" wide x 79" deep x 90" tall. Since the overall depth is 79", there is no plausible of the switchgear overtuming due to DBE and the embedded channel's shear capacity is judged adequate (see S&A Calc.).

For the anchorage analysis conservatively consider the last 3 bays, for which the last bay is unanchored. Also, consider each bay weighs 3300 lbs and the plug welds' equivalent 1/8" fillet lengths are as computed in the referenced S&A calculation (see 1 A-05 for calculation excerpts).

The anchorage analysis yields a safety factor of 2.265 for the welds and the referenced S&A calculation computed the a safety factor of 1.69 for the embedded steel, hence the switchgears' anchorage safety factor is 1.69.

The SRTs are R. P. Kennedy and A. R. Bayer - 10/25/93.

REF: Bechtel Dwg. C-103 Rev. 4 & C-196 Rev. 5 and S&A Calc. No. 91C2696-C-01,6 Titled "USl A-46 /

IPEEE, Equipment Fragilities for 1 A-05,1 A-06,2A-05 and 2A-06" Capacity:

BSCav.3: The SRT was not able to see the potential transformer. However, a review of the pictures in the component instruction manual showed the transformers on the sides and not an issue.

j BSCav.4: Switchgears 2A-05 and 2A-06 are adjacent to each other and consist of a total of 10 bays interconnected.

Anchorage:

The bays, Westinghouse type, are anchored by 2 rows of fillet welds to embedded steel. The fillet welds run all

'around and half way around the holes (see attached field sketch). Each bay is 26" wide x 79" deep x 90" tall.

Since the overall depth is 79", there is no plausible of the switchgear overtuming due to DBE and the embedded channel's shear capacity is judged adequate (see S&A Calc.).

For the anchorage analysis conservatively use 1/8" fillets around the holes and consider first 3 bays, for which the first bay is unanchored. Also, consider each bay weighs 3300 lbs as computed in the referenced S&A calculation (se91 A-05 for calculation excerpts).

The anchorage analysis yields a safety factor of 2.261 for the welds and the referenced S&A calculation computed the a safety factor of 1.69 for the embedded steel, hence the switchgears' anchorage safety Sctor is 1.69.
