INTRODUCTION I

Various' insulated conductors and: insulated electric cable samples were subjected to nuclear irradiation'and' a simulated Loss-of-Coolant '

Accident-(LOCA) in accordance with procedures recommended in.

- IEEE Std.- 383-1974.* - The cables, which are-described in'dctail 1n Sec tion 2 and in Table' 1,,were energized electrically and ' carried '

specified load currents-throughout.the LOCA simulation..

i Pre-LOCA and post-LOCA measurements involved flexibility,.high.

[

potential tests, and insulation resistance measurements.

The qualification testing progra'm described in'this report was

- conducted at The Franklin Institute Research laboratories'(FIRL) during i

the period-February 10, 1975-to April 14,~1975.-

3.2 RADIATION EXPOSURE All cables tested were subjected to. gamma irradiation flux from ay cobalt-60 source to a-minimum dose of 200;w garads.= Small-sections of color-coded multi-conductor = cables were-nnt lirradiated to permiti comparison -

of color retention after irradiation exposure. LA certification'of the 1

irradiation exposure is given in Appendix 3.

Energizing potentials on single conductor cables were applied b tween the conductor and the test chamber at ground potential. On multi-conductor cables the circuits shown in Figure 2 were used.

1 The cables were exposed to a steam / chemical spray environment for u

h 10 days in general accordance with the temperature / pressure profile 6

111ustrated in Fi ure 3 (see Section 4.3 for actual profile). Through-E o

[

i ut the 30-day exposure, the-cables were sprayed continuously with a

-}

chemical solution consisting of H)B03 (3000 ppm boron) bu'ffered with j

nodium hydroxide-to a pH of between 10.0 and 10.5 at room temperature (75 - 80F). The spray was applied at a rate that provided.0.15 gpm per.

TEST RESULTS-4.)

IRRADIATION EXPOSURE l'

As the result of 200 megarads of gamma radiation, there was no visible or experimental evidence of significant deterioration' of the :

single conductor cables and aged multi-conductor cables 10-and-11.. Cable 9 l

-exhibited various degrees of stif fness in the outer jacket. There was no i

evidence of se'rious fading'of the' color-coded conductor insulations in the culti-conductor cables. The results of the post-irradiation high-potential

l

[

l vithstand test are suennarized in Table 2.

1 4.2 STEAM / CHEMICAL-SPRAY EXPOSURE The actual temperature /pressere profile obtained.for simulation of the-l l.0CA exposure is shown in' Figure 4.- ' The results' of ~ the mandrel bend and :

1

, high-potential withstand test before and af ter the steam / chemical-spray tests are included in Table 2.

All cables-withstood, the bigh potential test..

• i Thesingleconductorcablesandagedcablesf10and11bintained their electric load in accordance wich'the energizing: potential'and currents indicated throughout the. steam / chemical-spr'ay profile. ' Unaged C.ihic 9 maintained its electric load throughout, the first dwell at 346'F.

D Ec load then was removed' temporarily (later reconnected).for reasofis utsociated with the test methods rather than the cabic. construction;*

Post-test inspection o f the cable samples showed that ~ there was-no-visible functional dacoge or noticeabic change in stiffness of the single

[

ennductor cables and cabics 10 and 11.

Although Cable 9 exhibited non-mi form stif fness and some jacket splitting during the mandrel bend test, i

there was no evidence of damage to the-individual conductors.

CONCLUSIONS i

8ampics of aged and unaged single conductor and multi conductor cables

..;;.11ed by the Brand-Rcx Company were subjected to environmental conditions e t.h are sore severe than. those that-are postulated to occur as the result-

.i toss-of-coolant accident (LOCA) in a nuclear-fueled power plant.-

The cabics withstood accelerated aging.. nuclear irradiation exposure 6

u.'00 x 10 rads, and a steam /r$ emical-spray simulating LOCA conditions.-

Min latter exposure included two rapid temperature rises to 300'F, two;

.c!!a at 346'F, and a continuing exposure.to steam and chemical-spray at

c reading temperatures for a-total duration' of; thirty days. i This ' test -

f

re, ram was conducted in general accordance with IEEE Standard 383-19741

(

Se single : conductor cables. and aged multi-conductor cables maintained 1

'.ct r electric load throughout the duration of the steam / chemical-spray i r.it !Io. The unaged multi-conductor sample experienced 'some - dif ficulty in l

!. l !!ng electric load because.of problems associated with the' test. methods.

I-a' At t he conclusion of the test program, all cables retaine' ehigh insulatio'n d

l l'" turance and withstood a high-potentf al withstand test while wound around '

P

.mJtels having diameters forty t'ines the respective Jcable diameters. -

It is concluded-that all of the single conductor and mult'i-conductor.

j

. eles are capable of-demonstrating adequate performance during and af ter il j

t., t conditions simulating-a LOCA in a nuclear-fueled power plant.-

Dear Mr. Steigelmann:

This will. summarize parameters pertinent to the irradiation of 14* clectric cabic samples per. your project C-4113.

i amples were placed in a Cobalt-60 gamma field ranging in c

intensity from 1.0 to,1,15 megarads.per hour, 'for a period of 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br />.

Cables-received a minimum. dose _of1200 Mrad,_-

w'lile the - maximum overdose to any cable wass 1 '.15 times : the d

dose specified, or~230 Mrad.

The samples were rotated and turned during.cxposure.to.obtain i

the dose distribution described ~.

Irradiation was conducted--

in air at, ambient ' tempera ture and pressure. _ Rad.ihrst heat -

o from the source heated the-samples-somewhat, but the: temper c

Tture-did not exceed 1100F, as indicated.by previous-measure-nents on an oil' solution in_ the same relative; position..

DosimetrywasperformedbsingaVictoreenModelSSS-Integrating Dose Rate Meter and Probe.. The unit-was calibrated on January 15, 1974 by the Victoreen Instrument Company,- using l

cobalt-60 and cesium-137' sources whose calibrations are traceable to the U.S. National Bureau'of Standards.

A copy of the calibration certificate-is available.

nackup dosimetry i

using a Red Perspex system confirmed the Victorcen readings.

.j Irradiation was completed on Starch 3,-1975, ramples were picked up by your personnel and transported-back to PIRL.

• The 14 cables consisted of the 11 described in the covering Very truly yours, report plus 3 others of a l

C ONNE CTIC UT 04329 4 (8039433 7771 WIRE AND CABLE OlVISION pg ]3 SECTION VI QUALIFICATION DATA l.ONG IERM IHERMAL AGING ARRHENIUS PLOT 210 YEAR LIFE GENERAL:.The following information outlines our approach and technique in verifying the 40 year service life of our T-162 cross-linked polyethylene insulation.

PURPOSE:

To establish a thermal aging point-in terms of short time and high temperature which represents.theilife of an insulation system over a period:of 40 years at

(

g the standard 900C operating. temperature.--

ARRHENIUS TECH'.IOUE :

The arrhenius equation is generally 3 consicered to be the best: method of approximating the relationship between. insulation ~ life.and temp-erature applicable to the service' life'of an insul-~

ated conductor. By selecting aging temberktures well above the' expected normal operating temperature (90 C).

C and establishing a failure criteria, a set of. data points can be plotted.

From t!.is plot, an indication of insulation performance at.90 C.for'40 y_ ears can 0

be extrapolated,by short-term (typically one week) i high temperature agings.

BRAND-REX APPROACH:

Sample Descristien -

IMOMMIM OU 1

The samples consisted of a 30 mil wall.of XLPC T-162 on a

1. 12 AWG 19 strand bare copper conductor. The insulation was colored white.

~

Samples were prepared in two ways. Ten groups 7f three samples were prepared by stripping the insulation from the conductor to make standard specimens for tensile and elongation measurement. Secondly, four samples 8 feet g

g long were made into 6 inch coils for dielectric strength t

measurements.

Aging -

d Aging was accomplished by placing samples-of the insulation in ovens at four different temperatures and aging until failure occurred, j

Three Blue

'M' forced draf t ovens were used in this test.

One of the ovens was used for two different temperatures.

All three ovens satisfied the requirements of ASTM-D-2436.

l The air flow was adjusted to give approximately 150-air0 changes per hour.. Thg four test-' temperatures were 113 C, 0

121 C, 136 C, and 150 C.)

Failure Criterien -

i l

Testing for failure was accomplished by-two methods. At a

specific intervals one group of three tensile samples was removed frem the oven, cooled for.24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at-room temp-erature and tested for tensile and elongation according.

~

to standard i.dustry practices.' Secondly, appr,oximately".8 inches were cut from each of two coils and cool'ed for 2u 4

hours at room-temperature.. Each coil was.then attached to l

I a mandrel whose diameter was eight times the di'ameter of l-the insulation while a 1.5 pound weight was attached to-the other end.

The sample was then wound.on the mandrel both clochwise and counte'r'-clockwise, twice.in:each direction'. Upon removal from weight and mandrel the sample l

was examined for cracking if none were observed it.under-went a dielectric test.

1 The dielectric test consisted of'a one hour soak in a '1% '

Nacl-h'ater solution. While the sample was still immersed l

4 KV AC was applied for 5 minutes. The voltage was applied at a rate of 150 volts /second. If no-failure was observed the voltage was increased at 500 volts /second until the sample broke down. The wall thickness was then measured at point of failure.

BRAND-REX APPROACH - cont'd.

Tailure was considered to be the failure of the insulation to withstand the 4 KV-AC for 5 min'ates or if cracking were observed in the mandrel test.

The.ansile and elongation measurements were made only to correlate with the dielectric I

test.

They were not considered a criterion for failure.

j It is the opinion of Brand-Rex that a mandrel and dielectric test most closely simulates stresses found in actual use.

The failure times for this compound-are as follows:

Test Temeerature Tailure Time 150 C 3916 Hr.

136 C

'1068 Hr.

N hbf y

ARRHEN!US PLCT (ATTACHED):

The above temperature and failure times wer.e'used on an Arrhenius plot in which the log of time to,. failure is plotted against the reciprocal absolute temperature. It should be noted here that the Arrhenius technique is valid if only one ch,emical reaction is controlling the insulation aging process...Our cross-linked polyethylene is formulated with many ingredients, each reacting dif-forently with recpect to time and temperature. On this 0

basis, we feel the two lowest aging points 113 C and reprerantationof90[ Caging 121 C) are the closest consequently our plot is a at to point and.not a best.

fit straight line.

Since the Arrhenius plot is constructed from failure points, another line "uust be extrapolated to determine the passing 0

I 40 year 90 C insulation life and the cor::esponding short 0

term aging point. With the knowledge that the 113 C and 121"C aging points are more valid, the extrapolated u0 year plot was drawn parallel to both points and intersecting the 40 year 90 C-point. On thic prot lies the important short term aging point we have celected for our insulations,

TEST TACILITY 3.1 CABLE MANDREL At the start of the program, the specimens requiring thermal aging at 136'C (277"T) were wrapped onto a concentric arrangement of two stainless stosi mandrels visible in Figure 1.

The diameters of the mandrels were 16.2 in (0.41 m) and 19.8 in (0.50 m); the lengths were 33 in (0.84 m).

The mandrel was also used during gassna irradiation and the simulated SLB/LOCA exposure (Szetions 4.3 and 4.$).

3.2 THERMAL ACING OVEN I

The specimens were thermally aged in a forced-circulation air oven with interior dimensions of 3 ft by 3 ft by 4 ft high (0.9 m by 0.9 m by 1.2 m high).

The oven temperature was recorded by a self-contained temperature recorder and verified by thermocouples and another strip chart reco'rder.

.3 GAMMA IRRADIATIO!' TACILITIES The gamme irradiation was provided by Isonedix, Inc.,

a subcontractor to FRC.

The gammaa exposure facility consisted primarily of a large, flat array of cobalt-60 sources oriented in a vertical plane. The mandrel of cables is pieced in view of the gasuna source - and the mandrel is rotated periodically in 90-degree increments to obtain a uniform dose. Gamma irradiation is accom-plished with both the mandrels and the ganssa sources in an air environment.

1 3.4 STEAM /CREMICAL-SPRAY ENVIRONMENTAL CHAMBER The test vessel used for the steam / chemical-spray cxposure was a 24-in t

(0.61-3)-diam by 48-in (1.2-m)-long stainless steel cylinder schematically I odel POM-3660, Blue-M Equipment Company, Blue Island, IL.

head of the vessel. An overall view of the facility is provided in Figure 3.

Steam was admitted to the test vessel through a central 1-1/2-in NPT (approx. 41 mm) pipe, which exce.a.ci tmm through the center of the cable man-drel. Several sections of the pipe were perforated with 0.25-in-(10-mm)-diam holes to disperse the steam (see Figure 2).

The perforated sections were sur-l i

rounded by concentric sections of 3-in (76-um) pipe to baffle the steam and' l

,I prevent its direct impingement onto the cables, j

d An array of spray noseles' consisting of two nozzles in each of four "1

quadrants was provided as shown in' Figure 2 such that the cables were sprayed with chemical solution at appropriate times.

I 1

l The vessel was equipped with several thermocouples to measure and record the temperatures of the vapor in the vicinity of the cables and of the fluids which collected in the bottom of the vessel..The vessel pressure was indica-i ted on a dial gage and recorded on a strip chart. 'A list of data acquisition o

i instruments used in the test program is provided as Appendix A.

e. '

power supplies were provided to energize the test cables with the voltages and currents listed in Table 1 and schematically presented in' Figure 4.

The circuits included a circuit breaker which would disconnect the applied poten-j tials if the leakage / charging current exceeded 1.0 A.

TEST PROGRAM The test program was designed to simulate a steam line break (St.B) and loss-of-coolant accident (1,0CA) and the cooldown period following the accident.

The program included thermal aging, samma irrediation, a 30-day steam / chemical-spray exposure, and a mandrel bend and high potential-withstand test. Selec-tion of the test sequence was guided by IEEE Std 323-1974 and IEEE Std 383-1974.2 4.1 PRETEST INSPECTION AND MEASUREMEh7S The cables were visually inspected and identified, immersed iu room temperature tap water for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, and subjected to insulation resistance (IR) measurements at a de potential of 500 volts held for 1 minute.

I 4.2 THERMA 1. ACING Cables 1-3, 2-3, 3-2, 4-2, 5-2, 6-2, and 7 were wrapped on' stainless steel ndrels (see Section 3.1) and placed in a forced circulation air oven at 136 C j'

(277'F) for 7 days (168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br />).

Cables 1-4, 2-4, and 3-3 were coiled and sup-ported on a hose hanger in the air oven at 158 C (317 F) for 7 days (168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br />).

l

See Table 1 for a sununary of thermal aging. After the. mal aging the IR of the cables was measured.

4.3 CAMMA IRRADIATION The cables thermally aged at 158 C (317 F) and the unaged cables were added to the stainless steel mandrell all cables were exposed to an air-equivalent dose of 200 Mrd (minimum) of gansna radiation from a cobalt-60 source.

The average dose rate was 0.63 Mrd/h.

F-C5120-1 4.4 PREPARATION TOR STEAM / CHEMICAL-SPRAY EXPOSURE i

i I

the mandrels with cables were attached to the head of the test vessel, j

and the assembly was lowered into the vessel.

The cable ends were routed out 4

of the vessel through NPT pipe fitting penetrations;. the cables were pressure sealed in the fittings using an epoxy. A pretest view of the cables is shown-i in Figure 1.

l The ends of the cables were connected to circuits of Figure 4 to provide t

the potentials and currents listed in Table 1.

A siew of typical arrangements is provided in Figure 3.

l 4.5 STEAM / CHEMICAL-SPRAY EXPOSURE i

i 1

The cables were subjected to a steam / chemical-spray (S/C) exposure in accordance with the profile of rigure 5.

Tresh chemical spray was used for I

1/ hour minimum at 346 F (174 C); thereafter, the spray solution was recir-4-

culated from a pool of solution collected in the bottom of the vessel. The chemical spray consisted of 6200 ppm boron as boric acid, 50 ppm hydrazine, h, sufficient sodium triphosphate to obtain a pH of 8.5, followed by sufficient I

sodium hydroxide to obtain a pH of 10.0 at room temperature.

The spray was applied at the total flow rate of 3.5 gpm (13 L/ min), which was calculated to Provide a spray intensity of approximately 0.27 sps/ft2 (11 (L/ min)/m )

2 over the cylindrical area of an imaginary cylinder located midway between the inner and outer mandrels.

See Section 3.1 and Figure 2.

The pH of the recirculated spray solution was measured daily during the 30-day exposure; when the measured pH level decreased to 9.0 the pool of spray liquid was replenished or completely replaced with fresh solution to restore a i

pH of 10.0.

See Section 5.4 for a discussion of actual spray chemistry during the exposure.

i The cables were electrically energized with the potentials and currents of d

Table 1 during the S/C exposure.

If a cable caused the power supplies to be disconnected, the cable was removed frce the circuit, and the potentials and currents were restored to the remaining cables.

... 1.mys rs C m.,

?

l i

e T-C5120-1 The IR of the specimens was measured prior to the start of the exposure e

and at intervals during the exposure (see Figure 5).

The measured IR during f

the 30-day exposure included the IR of extension cables and terminal blocks used to connect the specimens to the energizing circuits.

4.6 FINAL INSPECTION AND TESTS t

Af ter the steam / chemical-spray exposure, the cables were removed from the test vessel and wrapped around a mandrel having a diameter 40 times the cable j

diameter (see Table 1 and Section 5.5),

The cables were inspected for cracks and tears while bent.

I 4

k'hile 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-potential-i withstand tests at ac potentials of 80 volte per mil (3150 volts per aun) of i

i insulation held for 5 n;inutes. At the end of 5 minutes, the leakage / charging I

l l

currents were measured.

4.7 ACCEPTANCE REQUIREMENTS The test specimens were considered to have met the requirements-of IEEE Std 383-1974,3 Section 2.4, if they (a) remained energized with rated po-y I

tential and service current during the S/C exposure, and (b) passed the final bend and high-potential-withstand tests.- It was assumed that the first cri-t terion was met if the total leakage / charging current of the specimens con-I nected to an energizing source did not exceed approximately 1.0 A.

TEST RESUI.TS 5.1 INSULATION RESISTANCE l

R2sults of IR measurements obtained during the test program are suammarleed in Table 2.

IR measurements made during the S/C exposure include the IR effects of extension cables and terminal blocks used to connect the specimens to ener-gieing circuits: the effects usually cause a small reduction in measured IR.

5.2 THERMAL ACINC The specimens that were thermally aged at 136 C (277 F) for 7 days appeared to be in generally good condition; there was no significant difference in flexibility from that observed before the thermal aging.

Minor blocking, i.e.,

sticking, occurred between turns of some npecimens.

The red-colored adhesive in the heat-shrinkable splice of Specimen 7 apparently melted, and some of the ad-hesive flewed out of both ends of the splice.

/ 3 The specimens that were thermally aged at 158 C (317 r) for 7 days were

% ) flexible.

stiIl Some loops of cable were sticking together but could be easily separated.

Minor impressions were lef t in the insulation of Specimen 3-3 where t h e-cable was supported in the aging oven and where fiberglass ties were used to festen the coils of cable. There were no cracks or other irregularities observed..

5.3 CAMMA IPJLADI ATION After being exposed to an air-equivalent dose of 200 Mrd, most of the 4

specimens appeared to be in good condition. The jackets of Specimens 6-2 and I'

7 appeared to be stiffer than the jacket of Specimen 6-1. (Specimen 6-1 was l

not thermally aged.) There were no cracks or other irregularities observed.

The pressure and temperature histories for the first 16 minutes of e

cach transient are presented in Figures 6 and 7.

A temperature of 3000T (1490C) was achieverd in approximately e

8 seconds during the first and second transient.

A temperature of 3850F (1960C) was reached in 38 seconds during the e

l first transient and 35 seconds during the second transient. These I

temperatures were indicated by a thermocouple located approximately i

1-in (25 sus) inside the inner mandrel of cables.

l.

i l

a Within 15 minutes after the 12-minute superheated steam dwells, the l

minimum and maximum indicated temperatures were less than 100F (60C) l i apart. The average vessel temperature was maintained within 2100T I

]

(160C) of the required temperatures except for one overnight maximum i

drift downward of 300F (180C) from the required temperature of 3170T

{

and for occasional temporary downscale maximum excursions of 200r(110C)

e dwells at 3460F (1740C).

Thereafter, the solution was recirculated as planned. The solution was either replenished or completely. replaced I

a Local of 17 times to restore the fluid level and/or the pH value. The 2

lowest pH value measured was 9.0 except for one reading of 7.0 which was obtained 3.1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> af ter the start of the' first transient; a few minuten 2

thereafter the recirculating solution was replenished with fresh spray I

~

which was used to cool the vessel to 1400r (600C).

See Figure 5.

\\

i The specimens remained energized throughout the 30-day exposure except

[

during IR measurements and during short intervals to deenergize Specimens 5-2, l

6-1, 6-2, and 7 for reasons probably-associated with the vessel penetrations.

I l

1 l

l After the 30-day S/C exposure, the contents of the test vessel were exam-J ined, and although some cable jackets were split, the inspection report did not indicate that any cable materials fell off.

CONCLUSIONS j

Eighteen aged and unaged insulated and jacketed-electrical cables sub-citted by Brand-Rex were subjected to a test program based on the guidelines

{

of IEEE Standards 323I and 383,2 including 2 x 10 rd of gansna-irradiation, 8

and simulation of a combined steam line break and loss-of-coolant accident (SLB/LOCA). Throughout the SLB/LOCA exposure, the specimens were energized 1 *'

(exce'pt those specimens which were removed from the circuits) with maximum-roted potentials and currents. At the conclusion of the simulhted SLB/LOCA g.

_p expo su re *, all specimens were subjected to a' mandrel wrap test and high-

[I potential-withstand test.

All specimens, except 5-2, 6-1, 6-2, and 7, remained energized duringithe SLB/LOCA exposure. All specimens, including 5-2, 6-1 6-2, and 7, demonstrated I

a substantial margin of life remaining following the SLB/LOCA exposure by re-

.i taining a hv'- levet snsulation resistance and withstanding post-LOCA bend l e,p4, high po t u.t..

astand tests with the specimen insnersed = in-water.

l The need to remove Specimens 5-2, 6-1 6-2, and 7 before the. conclusion 3

! of the SLB/LOCA exposure was probably due to faults that developed in the ves-sel penetrations which were not representative of an actual installation in a

-nuclect power generating station.

These specimens performed' satisfactorily l]

lfor at least 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of the SLB/LOCA exposure and the post-LOCA ' bend and 1

Lhigh-potential-withstand tests.

Based on this and'further analysis-reported

'i

!in'a supplemental letter, it is possible that Specimens 5-2, 6-1,-6-2, and 7 would have performed satisfactorily throughout the SLB/LOCA test if the pene-(<

ltration faults had not developed.

GENERAL FRC PROCEDURE FOR CALIBRATION OF INSTRUMENTS TO

' ME ASURE TEMPERATURE, ELECTRICAL CURRENT AND LlOUlD FLOW RATE A Lest of Date Aceuisition Instrumena ihereetser consed Instrument List) used to measure or record data

@tteened durmg thes test proprem is appended. The following romerks are offered to assist the reader in understanding FRC proctice for calibrating instruments to measure temperature, electrical current and leguid flow rate.

g

1. Temperature Measurement in generol, environmental temperatures provided during even exposures and simuisted SLB/LOCA condition le.g., steam exposures) are sensed by thermocouples;their signals are displayed and recoeded by

-l strip chart recorders with appropriate electronic toforenceiunction compensation. FRC vees thermocouples cnd thermocouple wire purchased from - vendors who comply with ANSI Stenderd MC96.119?S,

Temperature Measurement by Thermocouples, fof limits of error (e.g., a 3/4% over 200*,to-700*F range tst ANSI type TI. FRC maintains its temperature recorders through a servies contract with recorder supphen who routmely clears, service and calibrate the recorders, treceable to NSS, e mmimum of once every four months. The reports of calibretion are on file et FRC.

To further substantiate the vedidity of temperature measurement by thermocouples, FRC maintains special calibreted thermocouples (calibreted et 32*,212* and 400*F) which am used encording to the following procedure:

On the dey a test is started, e celibreted thermoeouple is substitueed for one of.

the ANSI standard guelity thermocouples et the epocified oven or test vessel

- location. (The thermocouples are connected to the recorders with AN$letandard thermocouple extension wires: Jones. type terminal strips are oecesionally i

included with appropriate thermocouple metal sonnecting links.) The cali-breted thermocouple is placed in a dewer both of stirred isegester for approxi-

)

mately 30 : and then into en insulated fleek of eetreely boiling water for appron-imetely 30 s. If the recorder indicates the temperewees of freeting and boiling water within a tolerance of 2 2*F, the temperature measuring / recording system i

is considered adequessly calibreted for the purpocos of the test program. The above system ce/ibration procedure is repeated after nornpletion of the oven aging or SLB/LOCA esposure.

2. Electrical Measurement All electrical measurements are made by instruments with celibrations troosebne to NSS.Special circuits ere frecuently provided to supply current lesels requiring power current transformers, in these cases, sostrument current transformers are used in conjunction with 5 A movement emmeters to indicate the i

.l i

currents present in the test circuits. These panel mounted emmeters are cellbrated on a proprem by program bests against calibrated emmeters of higher quality, i

' 3. Liquid Flow Rate Measurement FRC calibrates its liquid flowmeets escording to the following procedure:

1-

• L The floweneser is insteiled in the FRC flow celibretion station, which has pro.

violons for adjusting and controlling the flow rete of top water through the l

flowmeter. The water is collected in a tank which rests on a beam belance. After l

L steady now is established, the time for a predetermined mens of water to flow t

through the flowmotor le memured; time measurements are made with en auto.

l metic electric timer. -

t Most FRC flowmotort ero of a consentric oritice, lese type (e.g., Daniel Flow Tube) with e differential.

pressure monometer le.g., Berton Dial Menometer). The ' orifice and monometer are calibrated as a system.

-1 l

although the instrumente see identified by esperate FRC item numbers. Both the monometer and the orifice -

ero lieted in the Instrument List.

4. Strip Chart Recorciers As noted in Section 1 above, strip chart recorders are serviced and relibrated a minimum of once overy four months. Some recorders respond to voltage inputs other than thermocouple signals and the amount of -

pen response can be controlled by ediustment of frontponel controls. For these recorders, pen response calibration is obtained on a program 4y-program beeis for the specific parameters being recorded. For l

esemple, to record prosaure 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 pen response. After g

calibration, the recorder input smplifier controls remain undenged, exeopt for oocesional minor aero<$ rift '

I adjustments. The actual calibrations appear on the st ip chart. The full span calibration level (e.g., O to 200 Poig full scale) is included among the'esete provided in the Instrument List.

Dear Mr. Paulson:

This will summarize parameters pertinent to the irradiatinn of one (1) mandrel wrapped with cable samples, as per your Purchase Order

. h No. 49029-A, dated August 17, 1979.

This is FRC Project No. C-5120 d \\

See attached sheet for specimen numbers.

The mandrel was placed in a Cobalt-60 gamma field and exposed 1at

')

each of 4 quadrants,.as marked on the mandrel.

By integrating the dose rate at any point on the mandrel ~during its 4 position exposure, an average dose rate.was obtained which, when multiplied by the total-j exposure time, yields total dose, j

The mandrel was exposed for a period of 328 hours0.0038 days <br />0.0911 hours <br />5.42328e-4 weeks <br />1.24804e-4 months <br /> at an average dose rate of 0.63 Megarads per hour.

The calculated-dose based on g, dosimetry is 207 Megarads.hosimetry system;.therefore the reported minimum d j

p Incorporating the 13% accuracy of the q

i Dosimetry was performed using Harwell-Red 4034 Perspex dosimeters

- J utilizing a Baucch and Lomb Model 710 spectrophotometer as the readout instrument.

This system is calibrated directly with 1BS, with the last calibration being May 30,~1979. :A copy of the dosimetry correlation report is available upon request.

Irradiation was conducted in air at -ambient temperature and pr. essure, i

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 October 13, 1979 and was completed on November 4, 1979.
