IDENTIFICATION OF CABLES TESTED Descriptions of cable specimens provided by the client are presented in Table 1 along with data on energizing potentials and currents. The cable-i specimens were the identical specimens previously exposed to a simulated 1

30-day SLB/LCCA environment.

The' cable lengths were 13 to 21' f t- (4.0 to 6.4 mi see Table 1), which are approximately 10 f t ( 3. 0 m) shorter than the original lengths due to the method of removing samples f rom the 30-oay. test t

vessel. Approximately 2 ft (0.6 m)' of the specimens for-this program were -

perlod following a 1,0CA.

The previous exposure ended with a 20-day dwell I

l at a temperature of 230'r (110'C) and a pressure of 10 lbf/in2 (69 kPa); the exposure of this program provided a temperature of 200*r (93'C) for 120 days.

l Selection of the temperature and duration was guided by the information in Appendix A to IEEE Std 323-1974.2 i

5.3 HUMID-A!R EXPOSURE

)

{

f The cables were subjected to a humid-air exposure at 200*r (93'C) and

)

atmospherie pressure for a period of 120 days. The humid-air environment was provided primarily by heating a pool of water in the bottom of the vessel, i

This method provided a very humid condition in the vicinity of the cables however, the relative humidity (AH) was not measured.

I The pH of the water in the bottom of the tank was maintained at a value of apptoximately 9.0 by periodic addition of sodium hydroxide.

The cables were electrically energized with the potentials and currents of Table 1 and Figure 2 during the exposure._ If the levels of potential and current drifted, they were readjusted to the specified values.

j If faulting in a cable or conductor caused tripping of the power supplies, the cable or conductor was disconnected f rom the circuit, and the potentials and c crents were restored to the remaining cables or conductors.

(

The insulation resistance (IR) of the specimens was measured once per T

week during the 120-day exposure. The energizing potentials and currents were i

removed f rom all of the specimens as required to perform the IR measurements.

5

{

5.4 r!NAI, INSPECTION AND TESTS Following the humid-air exposure, the cables were removed f:cm the test r

j vessel and wrapped around a' mandrel having a diameter 40 times the cable diameter (ree Tables 1 and 3).

While bent, the cables were inspected for cracks and tears.

While coiled at bend test diameters, the cables were-immersed in room-temperature tapwater for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (minimum) and then subjected to high-'

4 potential-withstand tests at ac potentials of 80.V per mil (3150 V per mm) of insulation held for 5 minutes.

At. the end of 5 minutes, the leakage / charging currents were measured.

$5 ACCEPTANCE REQUIREMENTS The test specimens were considered to have met the requirements of IEEE I

f Std 383-1974, Section 2.4, if they (a) remained energized with rated poten*

tial and current during the humid-air exposure and (b) passed the final bend t

and high-potential-withstand tests. It was assumed that the first criterion was met if the total leakage / charging current of the specimens connected to an energizing source did not exceed approximately 1.0 A.#

].

r c

?

1; 3See footnote 3 on page 2.

j 4Each energizing source supplied its ;Jtential to a circuit containing one b

or more cable specimens and extension wires. When the specimens are per-forming satisf actorily, the total leakage / charging current for each circuit, including extension wires, is usually less than 10 mA, or 100 times less i

than the assumed acceptance criterion of 1.0 A.

A. f ailing. specimen usually exhibits dramatic fluctuations and increases in leakage / charging currents which culminate in the tripping of energizing circuits (1.0 A maximum).

The f ailing specimen is usually incapable of being reenergized without continued.

or sporadic tripping of the energizing circuits.

TEST RESULTS I

i 6.1 INSULATION RESISTANCE l

Results of IR measurements obtained during the test program are sum-l matized in Table 2.

IR measurements made during the 200*r (93*C) exposure l

included the IR ef fects of extension cables and terminal blocks used to connect the specimens to energizing circuits: the etfects usually.cause a negligible reduction in measured IR except when the specimen IR is. very high (in which case the reduction is not significant to program objectives),

i l

i 6.2 HUMID-AIR EXPOSURE The 200*r (93*C) temperature.and humid condition was provided for 120 days (minimum) with the following deviations:

The vessel temperature decreased to 140'r (60'C; minimum temperature) o j

on one occasion when the building electrical power was turned of f for I

scheduled maintenance of power distribution equipment. Time that '

elapsed while temperatures were below 200'r (i.e.. the time for tem-i

(

perature to drif t downwards to 140'r, plus the time necessary to I

regain the temperature of 200'r) was approximately 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Approx-imately O.5 day at 200'r was added to the 120-day xposure (120.5 days total) to compensate for this 6-hour period'and to add to the conservatism of the program.

The temperatures indicated at'various locations within the test vessel o

differed by

+6',

~6'r

(+3', -3'C) from the average temperature.. The dif f erences we're caused by the stagnant condition of vapors within the vessel (i.e., the vapors were not stirred or circulated).-

l o

The median ter$perature (i.e., the' median of several indicated tem-

[

peratures at any one time) was maintained within a span of 190' to 210*r (80' to 99'C) for approximately 95% of the timer see~ next comment below, o On a few occasione, (e.g., during a weekend when the test was not being 5

monitored), the. rater in the bottom of the vessel evaporated to a level where terperature control was not completely ef factive. 'At these times, ressel temperatures climbed as high. as 224'r (107'C one thermocouples one location). Conditions were corrected on 'the next working days the addition of f resh water temporarily lowered the tertperature to 190'r (88'C) until restabilization at 200*r (93*C) was reestabitsbed. In general, these situations added to the conservatism of the test.

O o Temperatures drif ted downward approximately 10*F (6'C) when the cables were deenergized for IR measurements (i.e., of 1-hour durations, once per week). The drif t was caused by the loss of Joule heating normally centributed by the energized cab 1rs.

A humid condition was verified by 4 thermocouple immersed in the solution in the bottom of the vessel. The temperature indicated was approximately equal to the median of temperatures indicated by thermocouples located in the vessel vapors.1

"'he specimens were electrically energized throughout the 120-day imin: mum) exposure except as follows:

o All cables were deenergized for approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> every week as required to permit IR measurements.

o All cables were deenergized for approximately $ hours when the building power supply was turned of f for scheduled maintenance of power distribution equipment.

t o During a period of 19 hours2.199074e-4 days <br />0.00528 hours <br />3.141534e-5 weeks <br />7.2295e-6 months <br /> or less af ter 50 days of elapsed time, the l

circuit breaker controlling the 600-V potential tripped to the of t i

position during the night while the test was unattended. The tripping of the breaner was caused by a specimen not discussed in this report.

r-c5120-3 GENERAL FRC PROCEDURE FOR CALIBRATION OF INSTRUMENTS TO MEASURE TEMPERATURE, ELECTRICAL CURRENT AND LlOUlD FLOW RATE A List of Data Acquisition instruments (hereafter called instrument List) used to measure or record data obtained dutmg this test program is appended. Ties following remarks are offered to assist the readee in understandmg FRC practice for calibratmg instruments to measure temperature, electrical cuttent and lieved flow rete.

1. Temperature Measutement in general, environmental temperatures provided during oven earaosures and simulated SL8/LOCA conditions le.g. steam esposures) are sensed by thermocouples; their signals are displayed and recorded t,y.

strip chavt tecorders with appropriate electronic reference junction compensation. FRC uses thermocouples A

and thermocouple were purchased from vendors who comply with ANSI Standard MC96.11975 L. '

" Temperature Measurement by The mocouples," for limits of error le.g., ! 3/4% over 200*.vo.790 'F ran for ANSI type T). FRC maintans its tempeteture recorders through a service contract with tecuede, g

I supphers who routmuly clean, service and cabbrete the recorders, traceeble to NBS, a memmum of os.ca

-j I'

every four months. The reports of cabbration era on file at FRC.

To further substantiate the valedity of temperature measurements by thermocouples. FRC maintains I

special cabbrated thermocouples (cahbrated at 32', 212* and 400'FI which are used er. cording to the f ollowmg procedure:

On the day a test is started a calibrated thermocouple is substituted for one of the ANSI standard quality thermocous.les at the specified oven or test vessel location. (The thermocouples are connected to the recorders with AkSI.sdndard thermocouple entension wires; Jones. type terminal' strips are occasionally included-with appropriate thermocouple. metal connectmg links.) The cali.

brated thermocouple is placed in a dewet bath of stirred ice water foe approni.

mately 30 i ared then into en insulated flash of actively boiling water for appron.

imately 30 s. If the recordet indicates the temperatures of freerme and boiling

=

water within a tolerance of : 2'F, the temperature meesuting/ recording system is conudered adequately calibrated for the purposes of the test program. The above system c.##bration procedure is repeated af ter completion of the oven some or SLB/LOCA esposure.

2. Electrical Measurement j

All e!ectrical measurements are made by instruments with calibrations traceable to NBS.Special circ are frecuently provided to supply current levels requiring power current transformers. In these cases mstrument-current tsansformer'. ase used in conlunction with 5 A movement emmete y

currents present m the test circuits. These panel mounted am.weters are calibrated on a program by p

3. Liquid Flow Rate Measurement l

FRC cahbrates its liquid flowmeeers according to the following procedure:

The flowmeter is installed in the FRC flow calibration station, which has pro.

visions for adjusting and coittelling the flow rete of tap water through the flowmeter. The water is collected in a tank which tests on a beam balance, Af ter steedy flow is established, the time for a predetermined mass of water to flow through the flowmeter is measured; time measurements are made with art auto.

matic electric timet.

Most FRC flowmeters are of a concentric orifice plate type (e.g., Daniel Flow Tube) with a differ pressure manometer (e.g., Barton Dial Manometer) The orifice and manomelet are calibrated as

(

although the instruments are identsfied by separate FRC item numbers. 8oth the monomeret an are listed in the Instrument list.

4. Strip Chart Recorders l

As noted in Section 1 above, strip chart recorders are serviced and calibrated a minimu I

four months. Some recorders respond to voltage inputs other than thermocouple signals and 1

pen response can be controllec by adjustment of front panel controls. For thew recorders, pen calibration is obtained on' a program by program basis for the specahc parame'ers being te example, to record pressure the pressure transducer and the recorder are calibrated a known levels of presaute to the sensor and then recording the amount ofiocorder pen res' cettbeation, the tocorder input amplifier controls remain unchangeo,e'meept'for occasional ad ustments. The actual calibrations appeat on the strip chart. The full. span calibration lev i
