May 2. 1980 November 1979 through February 1980 Objective: ,

Demonstrate perf ormance of electrical cables for Class IE service in nuclear power generating stations in accordance with appropriate guidelines presented in IEEE Standards 323-1974 and 383-1974.*

Equipment Tested:

Five electrical cables. 1/C #12 AWG. with nonchlorinated flame-resistant. crosslinked poly-ethylene insulation.

Elements of Program:

The specimens were thertally aged for 240 hours0.00278 days <br />0.0667 hours <br />3.968254e-4 weeks <br />9.132e-5 months <br /> (10 days) at 150*C (302*F) and exposed to 220 Mrd (2.2 Cy) of gamma irradiation (air equivalent dose) f rom a cobalt-60 source at a rate of less than 1 krd/h (0.01 Cy/h) and then to a 33-day steam and chemical spray environment simulating a loss-of-coolant accident (1,0CA) and the cooldown followitg the 14CA. The simulated IDCA included two rapid  ;

increases in temperature to 346'F (174*C). two 3-hour dwells at 346'T (174*F) folloved by decreasing temperatures to a' final 29-day dwell at 212*F (100*C) and sage pressures of 4 to 9 lbf/ int (28 to j-62 kPa). The specimens were sprayed at a rate of 0.15 spa per square foot (6.1 L/s per square meter) of spray area for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with a chemical solution containing 0.23 solar boric acid (3000 ppa boron).

0.064 molar sodium thiosulf ate and suf ficient sodiur hydroxide to provide a pH of 10.5. After the 24-hour spray period. a high humidity condition was maintained by providing a pool of heated water in the bottom of the test vessel. The specissens were electrically energised with oc potentials of 660 V (nd currents of 11 A during the exposure, except for short periode to perform insulation resistance measurements to correct faulty circuits. Final tests consisted of a bend test (around a mandrel having a diameter of 40 times the cable diameter) and ac high-potential withstand tests at 80 V per mil (3150 V/mm) of insulation, i.e. 2400 V for the specimens reported.

Test Results:

The specimens remained energized during the 33-day simulated 14CA exposure (except for short periods noted above) and passed final bend and high-potential withstand tests.

-3.1 '.. CABLE' MANDREL Ati the start of L the progras, - the specimens' were wrapped onto a concentric <

arrangement of .two stainless steel mandrels visible in Figure '1. . The diameters

' of the mandrels were 16 in (0.41 m) and 20 in -(0.51 m); . the lengths were 33 in (0.84's). The' mandrel'was also used during samma irradiation mnd the eimulated SLB/LOCA exposure (Sections 4.3 and 4.5).

3.2' THERMAL AGING OVEN

, The specimens'were thermally aged in a forced-circulation air ovenI '

with interior dimensions of 3 f t by 3 f t by 4' ft high (0.9 m by 0.9 a-by 1.2.m high). ' The oven temperature was recorded by a. self-contained temperature re-corder and ' verified by thermocouple and another ' strip chart recorder. '

L3.3' GAMMA ~ IRRADIATION FACILITIES'-

- The gassna irradiation was provided by Isonedix, :Inc. ,3 a' subcontractor.

to:FRC. The gamma exposure facility' consisted primarily of a large, ' flat array of cobalt-60 sources oriented in e' vertical plane. . The mandrel of cables was .

placed in~ view of the gaiana ' source, and the mandrel was . rotated periodically

'in 90-degree . increments to . obtain a unifora dose'. Gamma irradiation was '

accomplished in air.

F-C5285-1 Steam was admitted to.the test vessel through a central 1-1/2-in NPT (approx. 41 mm) perforated'section of pipe, which extended approximately 6 in (0.15 m) into the test vessel,(see Figure 1). - The perforated pipe was sur-rounded by a concentric section of a 6-in (0.15-a)-dian pipe designed to baf-fle the incoming steam, thus preventing direct impingement onto the cables.

An array of eight centrally located spray nozzles *, consisting of two nozzle blocks with four nozzles each, was provided as shown in Figure 2 such that. the cables were sprayed with chemical solution.at an average rate of at

,least 0.15 gpm per square foot (6.1 L/s per square meter); this rate was based on a total solution flow rate of 2.5 gpm (0.16 L/s)- divided by the area of an imaginary cylinder' located midway between the inner and outer mandrels. Pro- -

vision was made to collect the spray solution in the bottom of the vessel and to recirculate the solution back through the spray nozzles..

g The vessel was . equipped with several thermocouple to measure and record the temperatures of the gas in the vicinity of the cables and of the fluids.

which collected in the bottom of the vessel. The vessel pressure was indicated on a dial gage and recorded on a strip chart. A list of data acquisition in-struments used in the test program is provided in Appendix A. 4 i

Electrical apparatus was prepared to supply an ac potential of 660 V and current of 11 A to the test specimens during the S/C exposure. The circuits included current-limiting breakers for disconnecting the applied potentials if the leakage / charging current exceeded approximately 1.0 A.

4. TEST PROGRAM The test program was designed to simulate a loss-of-coolant accident (LOCA). andL the cooldown pericx! following the accident. The program included thermal aging, ganma irradiation, a 33-day steam / chemical spray exposure, and j a mandrel bend and high-potential withstand test. The test sequence was chosen in accordance with guidelines in IEEE Std 323-1974Iand IEEE Std 383-1974.2 4.1 PREIEST INSPECTION AND MEASUREMENTS The cables were visually inspected and identified, immersed in room

~

temperature tapwater for I hour, and subjected to insulation resistance (IR) measurements at a de potential of 500 V held for I minute.

4.2 ' THERMAL AGDiG The specimens were wrapped on a 20-in (0.51-m)-diam stainless steel mandrel (see Section 3'.1) and placed in a forced-circulation air oven at 150 C (302 F) for 10 days (240 hours0.00278 days <br />0.0667 hours <br />3.968254e-4 weeks <br />9.132e-5 months <br />). After thermal aging the IR of the cables was measured.

4.3 GAMMA IRRADIATION The specimens on the mandrel were exposed to an air-equivalent dose of 220 Mrd (2.2 MGy) of gassna radiation from a cobalt-60 source. The average rate was 0.76 Mrd/h (7.6 kGy/h).

s t F-C5285-1 4.4 ' PREPARATION.'FOR STEAM AND CHEMICAL SPRAY EXPOSURE The mandrel with cables was attached to the head of the test veesel and i placed in the test vessel. The cable ends were routed out of the vessel through NPT pipe fitting penetrations; the cables were pressure sealed in the fittings .using a silicone RTV potting compound.

The ends of cables were connected to circuits to provide the ac potential of 660 V and current of 11 A. A view of typical arrangements is provided in Figure 3.

4.5 STEAM AND CHEMICAL SPRAY EXPOSURE The cables were subjected to a steam and chemical spray (S/C) exposure' in accordance with the p-ofile of Figure 4. Fresh chemical spray was used for.12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (minimum); thereaf ter, the spray solution was recirculated from a pool

- of solution collected in the bottom of the vessel. The chemical epray was terminated after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and a high-humidity condition was maintained thereaf ter by maintaining 'a pool of . heated solution in the bottom of the vessel.

The cables were electrically energized (see Section 4.4) except during intervals to measure IR and when a specimen not discussed in this report caused the power supplies to be disconnected. The faulting cable was removed from the circuit, and the potentials and currents were restored to the i

remaining cables.

The IR of the specimens was measured prior to the start of the exposure and at intervals during the exposere (see Figure 4). The measured IR at these times included .the IR of extension cables and terininal blocks used to connect l the specimens to the energizing circuits. j 1

L 4.6 FINAL INSPECTION AND TESTS ll Af ter the steam and spray exposure, the cables were removed from the test I vessel and wrapped around a mandrel having a diameter 40 times the cable 1RIV 6428, Silicone RTV Potting / Sealing Compound, General Electric Company, Waterford, NY.

5.1 INSULATION RESISTANCE Results of .IR measurements obtained during the test program are summarized in Table 2.

i 5.2 THERMAL AGING The specimens appeared to be in generally good condition after beiug

thermall'y aged at 150 C (302*F) for 10 d. The specimens were somewhat

stiff, but the cable ends could be bent without cracking. The specimens were slightly' discolored compared'to pretest appearances.

5.3 GAMMA IRRADIATION'

- Ihere was no apparent damage to the cables as a result of exposure to a

, - 220-Mrd (2.2-MGy). minimum air-equivalent dose except that they appeared some-

-what stiffer than reported in Section 5.2 above. There was also a greater }

amount of 'discoloution.

The certification of gansna irradiation is provided in Appendix B.

l 5A STEAM AND CHEMICAL SPRAY EXPOSURE The steam and chemical (S/C) exposure was provided in general accordance with the specified temperature / pressure profile illustrated in Figure 4. The specified temperatures were maintained within a span of +10, -5 F (+6,-3 C); temperatures l were maintained within a span of 15 F (13 C) during most of the 29-d dwell at-212 F'(100 C). The vessel pressure during the 29-d dwell at 212 F (100 C) l was maintained within the tolerance span of 4 to 9 lbf/in2 (28 to 62 kPa); the i vessel pressure was 5 lbf/in2 (34 kPa) for most of the time during the 29-d 1

L ,period. i The specimens remained electrically energized throughout the 33-d S/C exposure except during short periods to measure IR and to isolate faulting cables which were included in the test vessel but which are not among those discussed in this report. .

9 GENERAL FRC PROCEDURE FOR CALIBRATION OF INSTRUMENTS TO MEASURE TEMPERATURE. ELECTRICAL CURRENT AND LIQUID FLOW RATE A List of Data AcquisitionItattrumena (hereafter called Instrument iist) used to measure or record data obtained durmg this test pseyam is appended. The foHowing rernarks are offered to assist the reader in understanding FRC practies.ger celebrating instruments to measure temperature, electrical current and liquid flow rate.

1. Temperature Measurement in general, environmental temperatures provided during oven .xposures and simulated SLB/LOCA conditions (e.g., steam exposuses) are sensed by thermocouple; their signals are displayed and recorded by strip chart recorders with appropriate electroruc reference Junction compensation. FRC uses thermocouple . s., s and thermocouple wire purchased from vendors who comply with ANSI Standard MC96.11975. ,

Temperature Measurement by Thermocouple's," for limits of error (e.g.,13/4% over 200^.to 700'F range -

for ANSI type T). FRC maintains its temperature recorders through a service contract with recorder suppliers who routinely dean, service Ed calibrate the recorders, traceable to NBS, a mirumum of once every four months. The reports of calibration are 'on file at FRC.

To further substantiate the validity of temperature measurements by thermocouple, FRC maintains special calibrated thermocouple (calibrated at 32', 212' and 400*F) which are used according to the following procedure:

On the day a test is started, a calibrated thermocouple is substituted for one of the ANSI standardquality thermocouple at the specified oven or test vessel location. (The thermocouple are connected to the recorders with ANSl4tandard thermocouple extension wires; Jones. type termrnal strips are occessonally included with appropriate thermocouple. metal connecting links.) The cali- '

brated thermocouple is placed in a dewar beth or stirred ice. water for approxi. '

mately 30 s end then into an insulated flask of actively boiling water for approx. -

imately 30 s. If the recorder indicates the temperatures of freezing and boiling water within a tolerance of 2 2*F, the temperature measuring / recording system is considered adequately calibrated for the purposes of the test program. The above system cahbration procedure is repeated af ter completion of the oven aging or SLB/LOCA exposure.

2. Electrical Measurement All electrical measurements are made by instruments with calibration traceable to NBS. Special circuits are frequently brovided to supply current levels requiring power current transformers. In these cases, instrument-cu: rent transformers are used in conjunction with 5 A movement emmeters to indicate the currents pres (nt in the test circuits. These panel mounted ammeters are calibrated on a program by-program '

basis against calibrated ammeters of higher quality.

3. Liquid Flow Rate Measurement

. FRC calibrates its liquid flowmeters according to the following procedure:

]

• The flowmeter is installed in the FRC flow calibration station, which has pro-visions for adjusting and controlling the flow rete of tap water throu@ the flowmeter. The water is collected in a tank which rests on a beam balance. Afte steady flow is established, the time for a predetermined mass of weler to flow through the flowmeter is measured; time measurements are made with an auto.

matic electric timer.

Most FRC flowmeters are of a concentric orificeplete type (e.g., Daniel Flow Tube) with a dif pressure manometer (e.g., Barton Dial Manometer). The orifice and manometer are calibr although the instruments are identified by separate F RC item numbers. Both the manome are listed in the Instrument List.

4. Strip Chart Recorders -

As noted in Section 1 above, strip chart recorders are serviced and calibrated a minimum of once o four months. Sorne recorders respond to voltage inputs other than thermocouple signal (and pen response can be controlled by adjustment of frontpanel controls. For these recorders, pen res being recorded. For cahbration is obtained on a program-by program basis for the specific parameters example, to record pressure the pressure transducer and the recorder are calibrated as a s known levels of pressure to the sensor and then recording the amount of recorder pen respon calibration, the recorder input amplifier controls remain unchanged, except for occasional m adjustments. The actual calibrations appear 6n the strip chart. The full span calibration psig full scale) is induded among the data provided in the /nstrument List.

is o M E oix January 4, 1980 Mr. David Paulson The Franklin Institute '

20th and Cherry Streets Philadelphia, Pa. 19103

Dear Mr. Paulson:

This will summarize parameters pertinent to the irradiation of one (1) mandrel wrapped with cable samples, as per your Purchase Order No. 51780, dated December 10, 1979. This is FRC Project No. C5285.

The mandrel was placed in a Cobalt-60 gamma field and exposed at each of 4 quadrants, as marked on the mandrel. By integrating the dose rate at any point on the mandrel during its 4 position axposure, an average dose rate was obtained which, when multiplied by the total exposure time, yields total dose. l The mandrel was exposed for a period of 298 hours0.00345 days <br />0.0828 hours <br />4.927249e-4 weeks <br />1.13389e-4 months <br /> at an average dose rate.of 0.76 megarads per hour. The calculated dose based on dosimetry is 227 megarads. Incorporating the 13% accuracy of the dosimetry system, therefore, the reported minimum dose is 220 megarads.

Dosimetry was performed using Harwell Red 4034 Perspex dosimeters, utilizing a Bausch and Lomb Model 710 spectrophotometer as the readout instrument. This system is calibrated directly with NES, I

with the last calibration being November 30, 1979. A copy of the dosimetry correlation report is available upon request.

Irradiation was conducted in air at ambient temperature and pr ssure.

Radiant heat from'the source heated the samples somewhat, but the temperature did not exceed 850F, as indicated by previous measure- - .

y ments on an oil solution in the same relative position.  !

1 Irradiation was initiated on December 14, 1979, and was completed on December 30, 1979.  ;

i Sincerely yours, ISOMEDIX, INC.
