1.0 SCOPE 1.1 This test plan outlines the steps to be used by Gould Inc. Industrial

)

'O Battery Division to establish the qualified life of their stationary battery cells, as described in Paragraph 1.2.

The test program will

,be performed in accordance with the requirements of IEEE 323-1974, IEEE 344-1975 and as a guidance IEEE 450-1980 and IEEE 535-1979.

Seismic qualification of battery racks will be done by analysis on a job-by-job basis, and is not to be considered a part of this Test Procedure.

Cells to be tested are NCX-1680 type cells, which are in the mid-range size for this type.

IEEE 535-1979 states "that qualification may be accomplished by type testing".

It also states that " General practice is to qualify one or O;

more sizes of a cell type and interpolate or extrapolate to other size cells V

of that type.

Definitions Section 2, Page 5 defines Cell Type as cells of identical design, for example, plate size, alloy, construction details, but that may have differences in the number of plates and spacers, quantity of electrolyte, or length of container.

The aging mechanism and seismic test portion of the test program shall consist of the following sequence.

Specimens were owned and operated by New Jersey Bell Telephone Company in their Bordentown, New Jersey Central Office fer telephone standby service.

Cells are ten years old and have been operated in a full float method of charge @ 2.17 V.P.C.

Battery was located in an air-conditioned room with an average ambient temperature of 78'F.

Relative humidity was 40*..

Vibration level was

l.4 Test Cells The test cells used shall be naturally aged cells obtained from utility customer installations, thus. exposing the cells to actual operating conditions and natural environmental influences.

A description of each specimen source and operating conditions will be provided in the final report.

2.0 PRE-SEISMIC CAPACITY TE$T 2.1 Naturally aged test cells obtained from the utility customers will be transported to an outside test facility.

Test specimens to be inspe ted and evaluated at customer installation to assure suitability for qualification purposes.

2.2 Test cells will be given an equalizing charge per IEEE 450-1980 to ensure a fully charged condition.

Cells will then be placed on float charge at ambient temperature for 3 to 6 days prior to the Pre-Seismic qualification capacity test. MCX and NCX types will be on float charge @ 2.25 V.P.C.

average and FPR and FPS types @ 2.19 V.P.C. average.

Each three cell group voltage will be maintained through the float period within a tolerance of

+ 0.01 volt per three cell group.

2.3 Test cell electrolyte level will be maintained within 1/4 inch below and at the high level line during the float charge period.

2.4 Following the float charge period, a Pre-Seismic capacity test will be conducted at the published 3 hour3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months rate to 1.75 V.P.C. average per IEEE 535-1979 Para. 8.2.2 (1).

If the capacity test is less than 80 percent of rated capacity, the cells may be recharged, returned to float at ambient temperature for a minimum period of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months and retested.

If the cells fail the second capacity' test, the cells shall have failed.

PCT / 4.

3.0 SEISMIC QUALIFICATION (PER IEEE 344-1975) 3.1 Seismic Mounting and Orientation Each group of three fully recharged cells mounted in Gould-furnished racks, attached to a test lab-fabricated surface mounting fixture, hereinafter called the specimen, will be installed on a Multiaxis Simulator Table such that its longitudinal axis will be colinear with the longitudinal axis of the table.

For the second axis of the test, the specimen will be rotated 90 degrees in the horizontal plane.

The racks are designed so that the natural frequency of the racks is in the rigid region (above 33 cps.).

Rack calculations will be provided in the final test report along with transmissibility plots to demonstrate rigidity of the rack design.

O 3.2 Specimen Tie-down The mounting of specimen will simulate the actual in-service configuration as closely as practical, using standard intercell connectors, terminal plates, terminal cables and terminal hardware.

The test racks will be bolted to the test lab-fabricated surface mounting fixture. The surface mounting fixture will be welded to the shock table using 2" skip welds.

3.3 Excitation 3.3.1 Simultaneous Biaxial Excitation Each horizontal axis will be excited separately, but each one will be excited simultaneously with the vertical axis (longitudinal simultaneously with vertical, then lateral simultaneously with vertical).

The horizontal and vertical input acceleration levels will be phase incoherent during the multifrequency tests.

PCT /5

.__..m 3.3.2 Low-Level Resonant Search A low-level (approximately 0.2g both horizontally and vertically) sine sweep I

will be performed on each axis of the test configuration from 0.5 Hz to 35 Hz i

i to 0.5 Hz at a sweep rate of one-half octave per minute to establish major resonances.

Transmissibility plots of the resonant search will be provided in the test report.

1 3.3.3 Multifrequency Tests The specimen shall be subjected to 30-second duration simultaneous horizontal

{

and vertical inputs of random waveforms motions consisting of frequencies spaced one-third octave apart over the range of 0.5 Hz to 40 Hz.

The amplitude of each one-third octave frequency band width will be independently adjusted in each axis until the Test Response Spectra (TRS) envelop the i

Required Response Spectra (RRS) (Appendix III, IV or V).

!O The resulting TRS will be analyzed by a spectrum analyzer at 0.5, 1, 2, 3 and S percent damping and plotted at one-third octave frequency intervals over the frequency range of interest.

The Zero Period Acceleration (ZPA) of the RRS could be exceeded in order to meet the peak responses of the The horizontal and vertical inputs will be phase incoherent.

curves.

3.3.4 Operational Basis Earthquake (OBE) Tests l

Five OBE tests shall be performed in each test axis.

Duration of the OBE j

tests will be 30 seconds.

The TRS for the OBE tests will be analyzed at 0.5, 1, 2, 3 and 5 percent damping.

4 3.3.5 Safe Shutdown Earthquake (SSE) Tests One SSE test will be performed in each test axis. Duration of the SSE test will be 30 seconds.

The TRS for the SSE tests will be analyzed at 0.5, 1, 2, 3 and 5 percent damping.

PCT /6

i 4.0 INSTRUMENTATION

(}4.1 Excitation Control Control accelerometers will be mounted on the table at locations near the base of the specimen.

i 4.2 Specimen Response Eight specimen mounted uniaxial accelerometers will be provided during the i

l test.

Placement of the accelerometers will be as directed by the Gould Technical Representative and the Test Engineer. Control and specimen l

accelerometer plots at the required damping of the SSE test in each axis will be provided in the test report.

}

I Accelerometer placement will be similar to previous seismic tests performed by Gould at Wyle Labs, and used by many consulting engineers and utilities.

i All accelerometers will be placed in a proper position engineering-wise and will be located to provide the best possible, most meaningful results.

i l

Actual locations and photographs of accelerometer placement will be provided in the Final Test Report.

i 4.3 Electrical Monitoring i

~

One_(1) electrical monitoring channel will be provided by the test lab.

This channel will be used to continuously monitor the electrical discharge of the test cells during_the seismic test.

The discharge load will be approximately 2% of the three hour discharge rate of. the largest cell l

being tested on the shock table at the time.

Each 3 cell test group shall l

l be connected in series using standard inter-cell connectors and terminal plates with terminal cables to simulate installed conditions. When more than one 3 cell group is tested on the shock table simultaneously, all 3 cell groups will be connected in series to provide electrical monitoring of all groups during the test.

l 5.0 POST-SEISMIC CAPACITY TEST l

5.1 Following completion of the Seismic Test, each 3 cell group will be recharged 4

to replace ampere hours withdrawn during the Seismic Test. Ampere hours charge will be equal to 110% of the ampere hours withdrawn.

l Cells will then be given a Post Seismic Capacity Test at the published 3 hour3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months I

rate to 1.75 V.P.C. average per IEEE 535-1979 Para. 8.2.2 (1).

6.0 INSPECTION During and after seismic testing, the test specimens will be examined for abnormalities and the conditions recorded.

f 7.0 IN-PROCESS INSPECTION The records of TRS plots will be compared with the RRS plots to assure

]

compliance with requirements before proceeding with next test run. All i

vibration effects will be logged and analyzed.

7.1 The specimens will be examined for any damage following all tests.

If l

necessary, a physical tightening of hardware will be performed after each i

{

seismic test event, with justification expressed in Section 7. " Test Series Summary".

l I

7.2 During the seismic testing, the cells are connected in series and placed in a discharge mode. The series string voltage and current are monitored before, during and after seismic testing. Photographs will be taken of any noticeable physical damage that may occur as well as all specimen-mounted

~

accelerometers.

I 8.0 FAILURE CRITERIA A string of three cells must meet 80 percent of its 3-hour ampere hour capacity when discharged to an average final voltabe of 1.75 V.P.C.

If the initial Pre-Seismic capacity test indicates less than 80% of rated capacity, the cells may be recharged, returned to float at ambient temperature for a minimum period of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months and the capaci y test repeated.

if the cells fail the second capacity test, the cells shall I

have failed.

1 8.1 During the seismic test, the cells shall be electrically monitored for current or voltage fluctuations which could indicate circuit interruptions.

j If there is a failure, the failure shall be analyzed, the cause identified, and the designation of random or common mode justified.

8.2 If the failure is demonstrated to be random nature, the test will be repeated using a different group of naturally eged cells from the original or similar source.

If the failure is of common mode origin, the equipment is not qualified and Gould has two choices.

{See IEEE 535-1979 7.3 (1) and (2).]

8.2.1 The equipment can be redesigned.

4 8.2.2 A different group of naturally aged cells from the original or similar sources will be used for retesting.

Retesting will use the same or lesser TRS.

(Original TRS level was generically established to accommodate maximum anticipated future requirements.)

The lower level TRS selected will satisfy the required RRS.

bG PCT /9

1 9.0 GENERIC & CUSTOMERS' TEST REPORTS i

.m SECTION #2

/~'N TEST SPECIMEN HISTORY Q

1 1.0 SOURCE The test specimens submitted to Wyle Laboratories for a seismic simulation test program were naturally aged cells obtained from New Jersey Bell Telephone Bordentown Central Office, Bordentown, New Jersey 08505.

l 1.1 Calls were manufactured in Gould manufacturing facilities located at i

467 Calhoun Street, Trenton, New Jersey. Manufacturing date was 6/71 l

on Gould Order #T-62232.

Shipment was made to customer the same month.

Complete battere shipped consisted of 27 cells of NCX-1680 type.

The I

NCX-1680 desigr ; don is the Gould commercial identification.

This type cell when sold to Western Electric for resale to the Associated Bell Companies, is identified as a 27 KS-15544 List 508 battery.

This is

.the Western Electric method of identifying equipment classification and specific size. There are no design differences between the commercial i

and Western Electric type designations.

1 Final negotiations for acquisition of the test cells was with George F.

Hughes, Network Design, New Jersey Bell Telephone, Camden, New Jersey.

t 2.0 LOCATION OF BATTERY Battery was in service at the New Jersey Bell Telephone Central Office located at 195 Crosswicks Road, Bordentown, New Jersey 08505.

(_

PCT /15

_~__,

3.0 APPLICATION Battery was used for telephone standby service in the event of commercial A.C. power failure. The battery would, therefore, assume the function of

[

sustaining telephone equipment operation in such emergencies.

Battery was installed on a two-tier steel rack with cells #1-2 and #17-23 on the upper tier and cells #3 through 16 on the lower tier.

Emergency cells were #1-4.

Twenty-three of the twenty-seven cells are used in the 48 volt main string.

The remaining four cells are used as "End Cells" which are used during emergency discharges and are switched into use to sustain total system voltage requirements as the main string voltage declines during discharge.

l 4.0 CHARGING METHOD t

The battery was maintained on a float method of charge at an average of

)

2.17 V.P.C. a Western Electric Model 302A voltage regulated power supply.

5.0 BATTERY RECORDS Customer battery records are available for the first quarter of 1972 through the fourth quarter of 1980.

See Battery Records Section #3.

Battery is identified as 48 volt - String "B".

These records reflect quarterly individual cell float voltage readings on the 23 cell main string as well as cell voltage readings on the 4 cells in the I

emergency group #1.

O PCT /16

i

).

.0 BATTERY RECORDS (Cont'd.)

In addition, the records include semi-annual specific gravity readings of cell in the main string as well as those in the emergency group #1.

J Temperature readings of pilot cell electrolyte is also recorded.

e I

t 6.0 TEMPERATURE RANGE The battery area temperature was controlled by using air conditioning.

As reflected by the records, cell electrolyte temperature ranged from a low of 70*F to a high of 81*F.

Based on temperature data available, the average yearly electrolyte temperature was 78'F.

Relative humidity while not f

recorded was approximately 30 to 60%.

I Recorded temperature values reflect no greater than a 2*F spread in battery temperature at any given time.

7.0 OPERATING-MAINTENANCE PROCEDURES Battery has been maintained in accordance with Bell System Practices which.

are comparable with Gould Installation and Operating Instructions GB-3384-B.

8.0 RADIATION EXPOSURE The test specimens were exposed to normal background radiation for their operating life span of 10 years. There are no environmental specification requirements for other than low level background radiation exposure, therefore, test specimens did not receive augmented radiation exposure prior to the seismic simulation test program.

PCT /17

s

'.0 BATTERY USAGE (EMERGENCY PERIODS)

Batteries of this type are normally sized to provide three to five hours of energency power. Actual ampere load is a variable which is determined by total telephone subscribers handled as well as subscriber traffic which varies during a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months period as well as from day to dsy.

SECTION #4 DESIGN CONTINUATION DOCUMENTATION The cell design for batteries supplied for Byron /Braidwood as well as test cells submitted to Wyle Laboratories for seismic simulation testing are of the same design.

Included in this section are cell section drawings covering all cell sizes in the NCX line of cells.

Types Drawing #

Fig. #

NCX-600 through 1200 107006D Rev. F

4-1 NCX-1344 through 1500 107012D Rev. F

4-2 NCX-1650 through 1950 106288D Rev. K

4-3 NCX-2016 through 2550 106302D Rev. E

4-4 These drawings demonstrate that cell type NCX-1200 & 1500 being supplied for Class lE use is the same design as the NCX-1680 naturally aged test cells submitted to Wyle Laboratories for seismic qualification.

Additional documentation of design continuation is afforded by Gould Specification Sheets GB-3325 dated 6/71 (Fig. #4-5) current at the time the test cells were manufactured.

In addition, Gould Specification Sheet GB-3325 dated 2/80 (Fig. #4-6) is the latest issue and demonstrates design continuance for currently produced cells.

The revisions noted on the cell section drawings were minor dimensional changes, change of accessory options or redrawing of original drawing with no changes, d

The materials used in cell construction have remained unchanged and traceability can be provided.

() [ SECTION I. ABSTRACT In these calculations the natural frequencies of the rack are computed in all .1 principal directions, i.e., vertical transverse-horizontal and longitudinal-horizontal. Then the stresses in all members and connections of the rack structure are determined. The calculations are based on a static analysis of deflections of the component parts of the rack. The deflection of the individual components are then added arithmetically to find the deflection of the assembly in either horizontal and vertical direction. One section of the rack is used, as the other sections are 4 geometric repetitions. The sum of deflections of the individual components is always greater than the whole deflection of the entire structure. This is thus a conservative approach and hence the frequency calculated by this method results in a value on the safer side and adds to the safety of the rack design. Based on the deflection calculations, an equivalent system with single degree of freedom is defined and the natural frequency is computed. The frequency in all principal directions, vertical, transverse-horizontal and longitudinal-horizontal, is above 33 cycles per second. i {h The acceleration factors for seismic design are based on the Response Spectra s> given in Sargent and Lundy Specification Y-2819 fot Marble Hill Nuclear Generating Station Unit 1 & 2.

SECTION II. DATA AND ASSUMPTIONS 1. Rack Components The complete equipment consists of two (2) identical racks each containing 29 cells. Within each rack the cells are installed in two parallel steps, each step containing 15 cells and 14 cells respectively. The battery arrangement is shown in Gould Drawing 064745-D titled: Layout for 58 cell NCX-1200 Battery on 2-S07-074520-846 Rack (Heavy Seismic Res.) The approximate weights are listed on the Drawing as follows: NCX-1200 Cell 261# (1)-Rack S07-074520-846 1,015# 58 Cells NCX-1200 Battery & 2 Racks 17,275# The weight of the 58 cells itself is 58 X 261 = 15,138# equal to 87 percent of the total assembled rack and cell weight. Each step of each rack consists of 4 repetitive units 26 inches long aligned in a row with out to out length of 10 ft. The structural components of a unit are: - Stringers: Made of Unistrut Section P-1000 roll formed of #12 gauge strip steel. In addition to the support stringers on which the cells are mounted, there are side-and end-stringers. - Support Frames: Angles 2 1/2" X 2 1/2" X 3/8" welded with mitred joints, to form a four-sided rectangular frame. - Uprights: Structural tubing TS 3 X 3 X 0.25 - Bracing: Flat Bar 1-1/2" X 3/8" The properties of these sections are tabulated below: l PROPERTIES OF SECTIONS l X -.X AXIS Y-Y AXIS Designation Weight Area 1 S r I S r And Size Lbs/Ft in2 4 in in3 in in in3 in 4 Unistrut P-1000 1.625 X 1.625 X 0.105 1.90 .555 .186 .203 .579 .239 .294 .655 l Angle 5.90 1.73 .984 .566 .753 Same as X - X axis l 31/2 X 21/2 X 3/8" Structural Tube 3 X 3 X 0.25 8.80 2.59 3.16 2.10 1.10 Same as X-X axis Flat Bar 1.5 X 0.375 1.91 0.56 0.29 0.39 0.43 0.007 0.035l 0.101 .= 2. Seismic Acceleration The rack is designed for Safe Shutdown Earthquake S.S.E. and Operating Basis Earthquake 0.B.E. S.S.E. is the earthquake which produces the vibratory ground motion for which the battery must be able to perform its safety function. l This earthquake is expected to be the largest which could rationally occur at the site during the life of the plant. 0.B.E. is the earthquake which produces the vibratory ground motion for which the battery must be able to perform its intended function. 1 TABLE CF ACCELERATION FACTORS i 4 Horizontal Component Vertical N-S E-W 0.B.E. 1.35 1.75 3.20 l

The displacement in longitudinal horizontal direction is the sum of the deflections I of the end stringers, the upright and the bracing. l The weight of the unit consists of the weight of the cells and the weight of l the supporting framing, accessories and hardware. There are 58 cells in two l racks each consisting of 8 units. Thus the number of cells per unit is: n = 58/2 X 8 = 3.625. The weight of cells per unit is 3.625 X 261 = 946.13 lbs. The weight of the framing and accessories is 1015 lbs. per 8-unit rack, thus l 1015/8 = 126.87 lbs. Total weight of rack unit is 126.87 + 946.13 = 1073 lbs. p 2. Vertical Deflection 2a. Main Stringer The cells are placed on stringers spanning 26" between angle frames. There are 3 lines of stringers in each 4-span row.

SECTION IV. STRESS ANALYSIS ( l. General The stress analysis is done for O.B.E. and S.S.E. forces. The acceleration values are: (see Item 2 of Section II). 0.B.E. Horizontal 1.75 Vertical 3.20 S.S.E. Horizontal 2.40 Vertical 4.50 For determining the stresses multiply gravity loads For 0.B.E. Horizontal by 1.75 Vertical by 4.20 S.S.E. Horizontal by 2.40 Vertical by 5.50 All components of the rack are analyzed separately to demonstrate that the stress in each component is below the allowable stresses, as listed in item 3 of Section II. 2. Main Stringer The stringer is a four-span continuous beam with the maximum moment (see Moment Distribution item 2a of Section III) is M = 1/3 X 2651 = 883.67 in-lbs 3 The Section Modulus of the Unistrut stringer is sx = 0.203 in. For vertical acceleration sv = M/S = 883.67/0.203 = 4353 psi [\\ sy = 0.294 in For horizontal acceleration sH = 883.67 = 3006 psi 3 0.294 The stresses under seismic loads are found by multiplying the stress so by acceleration factors. For vertical loads the multiplying factor is 1 + a where a is the vertical seismic acceleration. As per Unistrut Tables, strength for cold formed member for bending is 25 ksi. This is to be used for 0.B.E. For S.S.E. stress increase of 33% = 33 ksi. Stress Under Stress in Main Stringer Under Seismic Forces Gravity Loads 0.B.E.

SECTION #7 TEST SERIES
~~SUMMARY~~
() WYLE TEST REPORT No. 44681-2 ( 1.0 SERIES 1 AND 2 The original testing procedure as defined in Gould Test Procedure GB-3454 up through Revision #10 dated November 14, 1980 was designed to attempt generic qualification of Gould plante and calcium type batteries for Class 1E application in nuclear power generating stations by using accele-rated heat aging of the test specimens. Test Series #1 and #2 disclosed that the accelerated heat aging resulted in degradation of cell components other than the positive and negative plates. The degree of degradation of certain components was in excess of that which would occur in actual service. Other components experienced ~. N-degradation that would not have occurred during actual service. This component degradation adversely affected the discharge capacity perfornance as well as the capability to satisfy the seismic requirements. Accelerated heat aging was originally employed to evaluate the electro-chemical performance and, specifically, the positive plate deterioration and its effect on discharge capacity delivery. No seismic requirement was involved. Based on the test results, it was concluded that accelerated heat aging was not a viable method to properly evaluate the complete lead-acid cell [N system with respect to discharge capacity and seismic requirement capability. %,A 4 PCT /31

Also Photographs III-13 Page III-42 and Photograph III-14 Page III-43. Deformation of cross braces which resulted was due to use of improper 3/16" thick cross braces as shipped from factory. Proper thickness (3/8") braces were substituted and testing resumed. 5.2 Cell Container Cracking - Specimen 2 See Anomaly 14 Page III-11. As addressed in 3.3 of this report, specimen #2 was a repeat test of an additional group of accelerated heat aged cells for comparison purposes with previously tested groups and is not part of this report. > O ( 5.3 Cell Container Cracking - Specimen 1 See Anomaly 14 Page III-11. The crack in the bottom of one cell (#3) container resulted in minimal loss of electrolyte. Specimen was removed from test table and transported to another test site. i 5.4 Ppst Seismic Capacity Discharge Test Test cells were recharged to replace ampere hours withdrawn during seismic testing (110% return). Post seismic capacity discharge test per IEEE 450-1980 IEEE 535-1979 was conducted on Specimen 1. At start of test, 16 hours had elapsed from time container (#3 cell) cracked until start of capacity discharge test. Electrolyte level at start of test was down 3/4" (lew level line). At end of 3 hour test, electrolyte level was down 1" (plates still covered). PCT /35

~~Note: Cell container cracked during seismic test releasing all electrolyte thus preventing capacity discharge evaluation.~~
Cell #3 with cracked container in Specimen 1 group delivered 92% capacity. Even though this capacity percentage satisfied IEEE 535 - 8.3.1.4 acceptance criteria, Gould did not classify this as acceptable. l 5.5 Cell container Cracking cause Examination of cell #3 container disclosed a crack in the bottom across the cell width dimension about 1" in from the bottom-jar juncture. The cell bottom upon returning to contact with the rack rails following a \\ vertical excursion during the test, did not return flush or perpendicular to the rack rails. Therefore, severe concentrated stresses resulted. PCT /36
) 5.5 Cell Container Cracking cause (Cont'd.) \\ Examination of the 1/2" thick urethane (open cell) spacer material used between cells disclosed considerable permanent compression. The com-pression was wedge shape, starting about 1/3 the way down from the top and extending to the bottom where the thickness was about 1/8". Both spacers between the three cells were in similar condition. This compression occurred during the side-to-side / vertical orientation operating basis earthquake tests. Due to the spacer permanent compression, uniform spacing between cells was not maintained during testing thus permitting undue independent j pendulous type movement. O I \\ 5.6 Conclusions Evaluations of conditions outlined in 5.3 and 5.4 were made and a decision made to repeat the testing of another 3 cell group of naturally aged NCX-1680 cells. In addition, the cell spacer material was changed to a foamed polyethylene (closed cell) material.

SECTION #7 ADDENDUM Stress Levels As indicated in comment on failure analysis of test series 5, the RRS was reduced cpproximately 40% at low frequencies (3-15 C.P.S.) along both horizontal and vertical axis during Test Series 6. Refer to Appendix III which is the original RRS used for Test Series 4 and 5. Appendix 4 portrays RRS for Test Series 6. The RRS for Test Series 6 are significantly above the RRS specified in the contract. In conclusion, the stress levels were considerably reduced in Test Series 6 compared to Te.st Series 4 and 5. [)WyleReportVol,ITableVPage-9 GJ Cell No. 6 should have pre-seismic capacity of 98% as supported by test disclosure data sheet 11-69 dated 6-19-81. This was a typographical error by Wyle, and, cecondly, this cell is not a part of qualification group. How To Derive Capacity The temperature correcti'on was per I.E.E.E. 450-1975 (Table 1, Page 11) which corrects the capacity in terms of time and not current. This correction term was used to t'cuparature correct capacity of each cell individually. Example: Cell #6 of Page II-69 Starting temperature is 82* The'Aorrectionfactoris1.014 Time re'quirement at 82* is (1.014 X 180 =) 182.5 minutes g _.) The capacity is (179 + 182.5=) 98.07% s PCT /72

This material has been standardized i for all Class IE or non-IE applications. This material can be readily identified by eompressing it with thumb and index finger. The original material (Urethane) g { vhen compressed, remains that way whereas the present ethefoam compresses and ^ ) then returns to its original dimension af ter pressure release. i Temperature 5argins l For every 15' rise in battery electrolyte temperature above 77', (92'F), the qualified battery life would reduce by 50%. Any prevailing annual average battery electrolyte temperature either within or beyond will affect battery life in direct proportion. ib i S / I PCT /73

SECTION #8 ) COMPARISON OF SEISMIC TEST TRS VG. RD.3 (NCX) Seismic test was conducted on naturally aged cells as described in Gould Test Procedure GB-3454 Revision #11. Gould response spectra at both 0.B.E. and S.S.E. levels at 2% damping (Fig. 5, 6, 7, 8 - Page III-24-25-26-27 in Wyle Report) were enveloped during the seismic test at all frequencies. Following comparison response spectra curves are provided at 2% damping: Fig. 8-1 Vertical operating basis earthquake front-to-back/ vertical Fig. 8-2 Horizontal operating basis earthquake front-to-back/ vertical I Fig. 8-3 Vertical operating basis earthquake side-to-side / vertical Fig. 8-4 Horizontal operating basis earthquake side-to-side / vertical Fig. 8-5 Vertical safe shutdown earthquake front-to-back/ vertical fig. 8-6 Horizontal safe shutdown earthquake front-to-back/ vertical i Fig. 8-7 Vertical safe shutdown earthquake side-to-side / vertical Fig. 6-8 Horizontal safe shutdown earthquake side-to-side / vertical l These plots compare the Byron /Braidwood R.R,S. and Gould R.R.S. with T.R.S. l T.R.S. envelopes Byron /Braidwood and Gould R.R.S. at all frequencies. l All the cells were capacity tested prior and after the seismic test as required by I.E.E.E. 535 documentation regarding the capacity test date as provided in r Section SA of this report. All cells met the capacity requirement. The cells \\ were also examined visually and no physical damage was observed. FCT/112-77b
The required transmissibility plots are provided in Wyle Test Report for Series 6 1 as follows: Test #1 Front-to-back/ vertical axis for both horizontal cnd vertical control accelerometers - Pages III-157 through III-160. Test #10 Side-to-side / vertical axis for both horizontal and vertical control accelerometers - Pages III-161 through III-164. These plots indicate that the fixture is a rigid one and amplification due its structure is insignificant. Section 5 and Section 6 of this report analyze the test fixture and contract rack j using static analysis approach to prove that both the test fixture and the contract racks are rigid structures. 1 i i l [ I DO ' PCT /46

SECTION #11 DYNAMIC CELL ANALYSIS ~ As described in this report, a battery three plate model was established using intermediate plates as mass points on the double cantilever beam. The busbar is treated as a center point of the cantilever. This model was analyzed using strudel software programming. It was determined that the NCX-1680 cell has a first mode at 92.89 hz whereas the NCX-2550's first mode occurred at 105.11 hz. This analysis establishes that the NCX-1680 and NCX-2550 are similar in behavior as far as vibration is concerned. As established in the other portion of this report, NCX-1680 and NCX-2550 ) are similar in design and also have the same materials for their component parts. The NCX-1680 weighs 332 lbs. whereas NCX-2550 weighs 496 lbs. The difference is due to the number of plates used in both designs. NCX-1680 uses 21 plates whereas NCX-2550 uses 35 plates. l f O PCT /ll-51

L i O' Sections #1and#7ofthistestreportdescribethemethodologyusedincarrying i out this test program. f Sections #2 and 3 demonstrate the origin as well as the environmental and i operating conditions to which the naturally aged test specimens were exposed. Section #4 demonstrates that the naturally aged test specimens and those cells i being supplied on the Commonwealth Edison Co./Sargent & Lundy contract for i Byron /Braidwood Project are of the same design and materials. Section #5 demonstrates that the test fixture used for this test program is adequately strong for the Gould required response spectra. D ) Section #6 demonstrates that the racks supplied under Commonwealth Edison Co./ ( Sargent & Lundy Engineers contract for Byron /Braidwood Project are also adequately strong and are rigid structures having natural frequency of vibrations above 33 hz. Section #7 summarizes the test series involving all naturally aged specimens. Each test series is comprised of pre and post seismic capacity discharge tests and random T multi-frequency vibration test.
