DESCRIPTION OF TEST FACILITIES

'HERMAL AGING OVENS 4.1 T

' eTwo therms.1 aging ovens were used. Specimens that were aged at 165 C (329 F) were placed in' a Blue-M forced-circulation air oven.

Specimens that were aged at to 121 C (250 F) were placed in a Tenney forced-circu-lation environmental chamber.

4.2 NUCLEAR RADIATION FACILITY Gamma irradiation was conducted by a subcontractor.

The gamma source was a flat array of cobalt-60 pencils. The irradiation was conducted.in air, and the specimens were located so as to be exposed to the required dose rate.

4.3 SEISMIC / VIBRATION FACILITY The seismic / vibration tests were conducted with the FRC electrohydraulic fs()

st*ker.

This has an actuator which can be aligned along angles of 0 to 90 degrees from the horizontal direction in 5-degree increments. The shaker table has a maximum double displacement amplitude of 8 in (2G cm) and a peak velocity of 44 in/s (1.1 m/s). Controls are available for single and multiple frequency vibrations. A view of the specimens mounted on the facility table is provided as Figure 3.

4.4 STEAM / CHEMICAL-SPRAY TEST FACILITY The steam / chemical-spray (S/C) test f acility consisted of the FRC 36-in (0.9-m) diam by 5-f t (1.5-m)-long horizontal test vessel illustrated in Figure 4.

Steam was admitted to the vessel through a 2-in NPT tee fitting at one end of the vessel for directing the steam to the side walls of the vessel.

A chemical-solution spray nozzle was positioned above and in f ront of the specimen enclosure to spray the front cover and top of the enclosure at an average spray intensity of 0.15 gpm/f t [6.1 (L/ min)/m } over the enclosure surface projected into a plane perpendicular to the axis of the spray nozzle.

• approximately through the middle of the enclosure. The spray intensity over a similar plane through portions of the enclosure closest to the nozzle was 0.18 gpm/ft [7.3 (L/ min)/m ),8 2

Six Type-T thermocouples were positioned at various locations around the specimen enclosure; and one thermocouple was located within the enclosure.

D e temperatures indicated by the thermocouples were recorded on scrip chart recorders along with vessel pressure.

4.5 WIRE-RETENTION TEST FACILITY i

ne wire-retention (pull) test facility consisted of an Instron tensile test machine.

The wires of the specimens were gripped with flat, serrated jaws. he tensile forces generated and the movement of the machine crosshead A

j were recorded on an ancillary strip' chart recorder.

TEST PROCEDURE 1

5.1 GENERAL TEST SEQUENCE

(

,The general test sequence and procedures were based on guidelines presen-ted in'IEEE Std 323-1974, IEEE Std 344-1975,- and IEEE Std 383-1974 The test plan and rationale are described in separate documents

the plan includes the following sequence of environmental tests

thermal aging, gamma irradiation, vibration aging, seismic fragility testing, seismic tests, and a 7-day exposure to a steam and chemical-spray environment. Functiornal tests of the specimens included contact resistance measurements, torque tests (of termi-nal strap screws), insulation resistance (IR) measurements, high potential-withstand tests, and final wire-rctention tests of the tubular-screw terminal

{

specimens and crimped-on wire lugs. The sequence of tests is illustrated in Figure 5, and the procedures are described in the following secticas.

5.2 RECEIVING INSPECTION AND SPECIMEN PREPARATION

/~~()

The specimens were inspected for any damage as a result of shipping and handling. The specimens were identified by inscription of the numbers (listed in Table 1) onto the cover plates of the one piece blocks and onto the mount-ing channels of the sectional assemblies.

Because of dif ferent thermal aging requirements (see Section 5.3), the specimens were mounted in two separate NEMA 4 enclosures identified as Nos. I and 2.

Both enclosures measured 20 in by 20 in by 6 in (0.5 m by 0.5 m 15 by 0.15 m) and included a mounting plate inside the enclosure and gaskets of EPDM elastomer, 11 See footnotes on page 2-1, 120utline of Qualification Test Program for Terminst and Fuse Blocks, FRC Plan P-C5143, Revised July 27,'1979, Franklin Research Center, Philadelphia,

l Fragility tests were conducted with the mounting table of the facility in i

i ha horizontal position and the actuator oriented at an angle of 45 degrees t

t lwith the, horizontal direction, as shown in Figure 9, to provide combined ihorizontal a.nd vertical (biaxial, in phase) vibration.

Fragility tests consisted of subjecting Enclosure 2 (with Specimens B, E, et, K, N, and Q) to multifrequency vibration over the frequency range of 1 to

/,0 Hz.

'Iba fragility test included one 30-second dwell at the maximum treility acceleration amplitudes at illustrated in Fi;1ure 10 and then

=f excining the specimens for absence of damage as a result of the vibration exposure.

If damage had been observed, the damage would have been repsired, and the test would have been repeated at lesser levels of i

i

cceleration amplitudes until the fragility level was established.

Since no i

i damage was observed at maximum facility IcVels, no further attempt was made to determine the fragility level and, the fixture and enclosure were rotated 90 l

da r es about its vertical axis, and the test repeated, i.e., 30-second dwell

..ir.imum acceleration amplitudes. The test was repeated af ter each of two additional 90-dsgree rotations of the table so that the spee' mens were t

subj cted to fragility test levels in each of the four orientations of the l

l sp;cimens, i.e., the horizontal vector (H ) was directed along the +X,

+Y, g

-X, cnd -Y directions, respectively, of Figure 9.

I The fragility test level became the basis for the levels used in the folicwing seismic tests.

"Ihe extension wires of the specimens were connected in series and to an ac current source of 0.25 A.

The current in the circuit was continuously tecorded on a strip chart recorder during fragility testing.

o

'I 4

20.Iha fragility test was initiated at maximum acceleration levels because of confidence in the ability of the specimens to survive the vibration i

,b)

S'eismic tests were conducted with the mounting table of the facility in tho horizontal position and the actuator oriented at an angle of 45 degrees with the horizontal direction, as shown in Figure 9, to provide combined horizontal and vertical (biaxial, in-phase) vibration.

Seismic tests consisted of subjecting Enclosure 1 with Specimens A, D, G, J, M, and P to multifrequency vibration over the frequency range of 1 to 40 Hz.

W e seismic test included five 30-second dwells at operating basis esrthquake (OBE) levels, followed by one 30-second dwell at the safe shutdown certhquake (SSE) level. n e specified SSE and OBE response levels, based on the results of fragility tests, are plotted in Figure 10.

After seismic testing was completed with the enclosure and specimens oriented as shown in j

Figure 9, the fixture and enclosure were rotated 90 degrees about its vertical i

axis, and the test repeated, i.e., at five OBE and one SSE level. The test 1

was repeated after each of two additional 90-degree rotations of the table so that the specimens were subjected to five OBE and one SSE vibration in each of g

the four orientations of the specimens, i.e., the horizontal vector (H ) was g

directed along tie +X, +Y,

-X, and -Y directions, respectively, of Figure 9.

O The extension wire-af the specimens were connected in series to an ac p.

current source of 0.25 A.

n e current in the circuit was continuously

recorded on a strip chart recorder during the seismic test.

After the seismic test, the specimens were subjected to IR measurements, contact resistance measuremeats (wire-conductor to wire-conductor as described in Section 5.5 and Figure 8), and an ac high potential-withstand test of 2200 V.

5.9 TEST ARRANGEMENTS FOR STEAM / CHEMICAL-SPRAY EXPOSURE with Specimens A, D, G, J, M, and P was installed in a 36-in (0.9-m)-diam vessel as shown ir. Figures 4 and 6.

ne ends of the connecting 1

wires were passed through pressure-sealing penetrations in the walls of the test vessel. The wires were connected to electrical circuits (see Figare 7) to provide ac potentials of 120 V and currents of 25 A.

Because fusible links in Specimen P fuses were likely to sof ten at the i

high temperature of the S/C exposure and interrupt electrical continuity, the fuses were replaced with nicket-plated brass tubes of the same dimensions.

See Table 1.

(This would not infer any inadequacy of the specimens, i.e.,

fuse holders.)

5.10 STEAM / CHEMICAL-SPRAY EXPOSURE The enclosure with specimens was exposed to a 7-day steam / chemical-spray (S/C) exposure in accordance with the temperature / pressure profile shown in Figure 11.

The chemical-spray solution consisted of 3000 ppn boron as boric acid, 0.064 molar sodium thiosulfate and suf ficient sodium hydroxide to ob tain a pH of 10.5 at room temperature.

4 During the S/C exposure, the specimens were et.ergized with the specified potentials and currents, except during short intervals to obtain IR measure-I ments; IR was measured at the times indicated in Figure 11.

().11 F'.NAL MEASUREMENTS AND TESTS l

Af ter completion of the S/C exposure, the specimens were visually inspected and subjected to an ac high potential-withstand test of 2200 V held for 5 minutes and a wire-retention (pull) test of 25 lb (11.3 kg) held for 1 minute. The wire-retention test was conducted by simultaneously pulling on a pair of wirt - connected to opposite sides of the terminal blocks. A crosshead speed of 0.05 in/ min (1.3 mm/ min) was used until 25-lb (11.3-kg) force was achieved. Af ter holding this force for 1 minute (minimum), the motion of the crosshead was continued until tha wire (s) pulled out of the specimen clamp or

)

other failure occurred.

The maximum force developed was recorded.

TEST RESULTS 6.1 THERMAL AGING Aq a result of exposure to 165 C (329 F) for 39.6 days, the Durez Specimens A through L were slightly discolored. W e tuhular-screw straps were moderately loose in their attachment to the blocks. The flat-screw straps exhibited varying degrees of looseness on their blocks.

Some captive screws on some of the covers were not captive when the covers were turned over. No other effects were observed, and the specimens appeared functional despite the apparent loosening between the conducting straps ard the insulating block., which contained the Durez specimens, was discolored, and the EPDM gasket was cracked and brittle.

We Reichhold Specimens M through Q did not exhibit any changes as the result of thermal aging at 121 C (250 F) for 8.3 days except for some discoloration (darkening) of the fuse-puller tabs on the fuse blocks (Specimens P and Q).

i The red-and green-colored insulated wires, also aged at 121 C (250 F),

f t

were somewhat darker. Neither Enclosure 1 nor its EPDM gasket was visibly 1

af fected by the thermal aging.

ne minimum value of IR measured was 1.4 teraohms.

i e

6.2 GAMMA IRRADIATION l

The only visible effect of gamma irradiation was some evidence of corrosion l

l on the screw heads and on the support brackets of the specimens. Here. appeared l

to be more corrosion and discoloration of specimens in Enclosure 2 than specimens in Enclosure 1.

Dere was minimal discoloration of Enclosure 1.

He minimum l

l value of IR measured was 510 gigaohms. The results of contact resistance mea-surements for Enclosure 1 are summarized in Table 3.

The certificate of gamma irradiation is presented as Appendix B.

6.3 FR#.dILITY TESTS The specimens of Enclosure 2 survived the full levels of tragility testing (Section 5.7 and Figure 9) without apparent permanent ef fe, cts.

The circuit gurrent of ti.25 A was maintained with occasional deviations within +0.05 A; the deviations are believed to have been caused primarily by vibration-induced movement of the fuses in the fuse-block clips.

6.4 VIBRATION AGING The vibration aging conditioning of Enclosure 1 and its specimens was provided as described in Section 5.6.

Post-vibration inspection revealed that only a terminsi-cover screw on Specimen J had become loose. FA 9ther apparent ef fects were observed. The circuit current of 0.25 A was maintained with occasional deviatioas within 10.05 A; the deviatirans are believed to have been caused by vibration-induced movement of the fuses in the fuse-block clips.

6.5 SEISMIC TESTING Enclosure I with specimens was subjected to test levels described in Section 4.7.

A typical SSE response is similar to that plotted in Figure 10.

A typical OBE rcsponse is provided as Figure 12.

During the seismic test, circuit continuity was maintained as evidenced by the continuous recording of circuit current. A nominal current level of 0.25 A was maintained with occasional deviations within 10.15 A.

The devia-tions in current are believed to have been caused primarily by minor movement of fuses within the fuse-holding clips of Specimen P.

The contact resistance measurements are included in Table 3.

The minimum value of IR was measured as 960 gigaohms.

The specimens of Enclcsure 1 withstood the application of an ac potential of 2200 V held for 5 minutes. At the end of the 5-minute per;od, the maximum leakage / charging current was less than 1.0 mA.

F-C5143 When replacing the fuses in Specimen P with dummy fuses (see Section 5.9 and foutnotes to Table 1), the fuse pulling tabs broke apart due to degrada-tion of the tab materials; the tab s were omitted from the rest of the program.

'6.6 STEAM / CHEMICAL-SPRAY EXPOSURE The S/C exposure was provided in accordance with the profile specified in Figure 11.

The required vessel temperatures were maintained within a span of

+8,

-5 F (+5, -3 C).

One thermocouple located just above the enclosure indicated temperatures 5 to 15 F (3 to 8 C) lower than temperatures indi-cated by other thermocouples: it is believed that the chemical spray, the tempe-rature of which was lower than t te temperature of vapors within the vessel, was impinging directly on this thermocouple.

Fresh spray solution was used for a period of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> minimum and then the solution was recirculated from a pool of solution collected in the bottom of the test ver sel. h e recirculated solution was replaced with fresh solu-f.

tion four times during the 7-day exposure. h e measured pH va'.ue was 9.0 to p

10.5 during most of the exposure; the measured pH was 8.0 to 8.5 for short L

periods preceding the aforementioned solution changes.

The specimens maintained their ac potential of 120 V and current of 25 A throughout the 7-day period except during short intervals when the potential f.

and current were removed to permit IR measutements.

he measurements of IR provided results which varied with the specimens measured, vessel temperatures. and elapsed time of the S/C exposure. h e one-piece terminal blocks (Specimens A, D, G, and J) provided the highest 'R mea-surements with values of 0.72 to 2.0 teraohms at 500 V during tie 'trat 3-hour dwell at 346 F (174 C).

The IR of these same specim9ns was measured as 190 kilohms at 100 V to 800 kilohms at 500 V during the second 3-hour dwell at 346 F (174 C).

h ereafter, the IR of Specimen D decreased to the low-est measured value of 300 to 500 kilohms at 10 V and 335 F (168 C), while 221R me'asurements were made with de potentials held for 1 minute. The 1

measurements included the effects of connecting wires and extension cables used in the energizing circuits.

F-C5143 Specimens A, G, and J remained in the higher range of 0.7 to 240 megohms at 00 V.

We' sectional blocks (Specimens M and P) provided initial IR measurements 23 of <50 kilohms at 10 V to 100 kilohms at 100 V during the first 3-hour dwell at 346 F (174 C).

he IR of these specimens gradually increased dur-ing the S/C exposure; the final IR measurements at 212 F (100 C) supplied values of 0.76 to 1.9 gigohms at 500 v.24 h e leakage / charging currents which energized the specimens at 120'V were le s.: than 200 mA during the dwells at 346 F (174 C).

The leakage /ch.=rging currents decreased to less than 5 mA for the remaining portions of the S/C 25 i

exposure.

t-Visual inspection of the specimens, af ter the S/C exposure, indicated the following:

l_

The outside of the enclosure showed signs of white-colored chemical e

deposits and a brown coloration at the bottom of the enclosure.

i he covers of the one p'.ece blocks (Specimens A, G, and J) were warped e

but held in place by at least one screw fastener. D e cover of Speci-I men D was also warped and was completely loose, i.e., the cover and the hinge wire were deteriorated, but the screw fasteners were in place.

j h e metal channels for Specimens M and P were corroded.

e he lef t-hand channel clamp or. Specimen M was loose and hanging at an e

angle.

o All specimens had moderate amounts of discoloration.

h e connecting wires and wire ties were in place and intact.

e ne interior surfaces of the enclosure were brown colored, and only e

traces of the original paint were observed.

The enclosure gasket was intact but stuck to the box rather than the e

Tqmperature Measurement in general, environmental temperatures provided during oven exposures and simulated SLB/LOCA conditions (e.g., steam exposures) are sensed by thermocouples; their signals are displayed and recorded by strip chart recorders with appropriate electronic reference-junction compensation. FRC uses thermocouples and thermocouple wire purchased from vendors who comply with ANSI Standard MC96.11975,

" Temperature Measurement by Thermocouples," for limits of error (e.g., t 3/4% over 200* to-700*F range for ANSI type T). FRC maintains its temperature recorders through a service contract with ritcorder suppliers who routinely clean, service and calibrate the reccrders, traceable to NBS, a minimum of once every four months.The reports of calibration are on file at FRC.

To further substantiate the validity of temperature measurements by thermocouples, FRC maintains special calibrated thermocouples (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-standard <1uality thermocouples at the specified oven or test vessel location. (The thermocouples are connected to the recorders with ANSI-standard -

2 thermocouple extension wires; Jones-type terminal strips are occasionally included with appropriate thermocouple-metal connecting links.) The cali-

=

brated thermocouple is placed in a dewar bath of stirred ice-water for approxi.

mately 30 s and then into an insulated flask of actively boiling water fo, approx.

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

l

2. Electrical Measurement All electrical measurements are made by instruments with calibrations traceable to NBS.Special circuits I

are frequently provided to supply current levels requiring power <:urrent transformers. In these cases, instrument-current transformers are used in conjunction with 5 A mnvement emmeters to indicate the currents present in the test circuits. These panal-mounted amrneters are calibrated on a program-by-program basis against calibrated ammeters of higher quality.

a. tioeia rie-n.. m e t remeet 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 rate of tap water through the flowmeter. The water is co!!ected in a tank which rests on a beam balance. Af ter steady flow is established, the time for a predetermined mass of water to flow through the flowmeter is measured, time measurements are made with an auto-matic electric timer.

Most FRC flowmeters are of a concentric orificeplate type (e.g., Daniel Flow Tube) with a differential-pressure manometer (e.g., Barton Dial Manometer). The orifice and manometer are calibrated as a system, although the instruments are identified by separate FRC item numbers. Both the manometer and the orifice 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 every four months. Some recorders respond to voltage inputs other than thermocouple signals and the amount of pen response can be controlled by adjustment of frontpanel controls. Fur these recorders, pen-response calibration is obtained on a program-by-program basis for she specific parameters being recorded. For example, to record pressure the pressure transducer and the recorder are calibrated as a system by applying known levels of pressure to the sensor and then recording the amount of recorder pn response. After calibration, the recorder input amplifier cor.trols remain unchanged, except for occasional minor zero<! rift adjustments. The actual calibrations appear on the strip chart. The full s7an calibration level (e.g., O to 200 psig full scale) is included among the data provided in the /nstrument List.

Philadelphia, Pennsylvania 19103

Dear Mr. Paulson:

1 This will summa'rize parameters pertinent to the irradiation of one (1) cardboard box and two (2) enclosure boxes mounted on a. metal i

structure, as per Purchase Order Number 51254, dated November 16, l

1979.

This is FRC Project Number C5143.

I The specimens were exposed for a period of 371 hours0.00429 days <br />0.103 hours <br />6.134259e-4 weeks <br />1.411655e-4 months <br /> at an average dose rate of 0.56 Megarads per hour.

The calculated dose based on dosimetry is 208 Megarads.

Incorporating the 13% accuracy of the dosimetry system, therefore, the reported minimum dose is 200 Meggrads.

Halfway through the exposure, the specimens were rotated 180 to give a more uniform dose distribution.

Dosimetry was performed using Harwell Red 4034 Perspex dosimeters utilizing a Bausch and Lomb Model 710 spectrophotometer as the CwiththelastcalibrationbeingNovember30, readout instrument.

This system is calibrated directly with NBS, 1979.

A copy of the dosimetry correlation report is available upon request.

Irradiation was conducted in air at ambient temperature and pressure.

Radiant heat from the source heated the samples somewhat, but the temperature did not exceed 85 F, as indicated by previous measure-ments on an oil solution in the same relative position.

Irradiation was initiated on November 21, 1979, and was completed on December 12, 1979.

Sincerely yours, ISOMEDIX, INC.
