IitTRODUCTl011:

The series of tests described a ! evaluated in this report were designed to demonstrate that the materials to be used in the Westinghouse V

Penetration assemblics for the S'runswick Station of Carolina Power and 1.ight Company will meet the requirements of United Engineers and Constructors specification //9527-01-118-1.

All cables, insulators, connectors, and potting compounds were tested, or' vendor reports received, to insure that.these materials will meet the steam, press'ure, temperature, fire, corros'ive outgassing,

- and radiation cr'iterions described.

b CONCLUSI.0;iS:

Westinghouse Electronic Tube Division certifies that all cables,

~ ' '

support insulators, insulating slaaving en conductors, saa!!ng ccepcunds, and connectors will:

Pass i:he applicable IPCEA or ASTM Flame Tests.

. The insulation resistance test was performed in a screen box in an

~

air conditioncd laboratory using a Keithley Model 610 SP. Electrometer

^

M.

and a John Fluke Model 413C High Voltage DC Supply. The dielectric strength tests were 'done on a $ E172A Corona /Ampacity Test Set.

Sampic sizes were limited to approximately six inches to insure

~

uniform Irradiation of the items to be tested.

Samples were prepared and' insulation resistance and dieler:ric strength measurements were made prior to irradiation testing.

One sample of ear.h item was not irradiated and used as a control sample.

The first irradiation test t'o simulate the 40 year normal environ-ment a cumulated dose was conducted I'n the het cell,in the Vard Nuclear t.aboratory at Cornell University.. The dose ra.te was 3.54XIE rads per 7

hour.nf enhalt 60 gamma irrediation for en ecomleted dose of 6. drin

' rads. The samples were remeasured for insulation res.! stance and dielectric strength. To simulate the one hour from accident dose the above samples were Irradiated in the hot cell at Brookhaven National 1.aboratory at a dese rate of 6.87X10 rads per hour for one hour and one minute. The samples were examined immediately upon withdrawal fiom the hot cell and showed t

no perceptable physi' cal damage or noticeable tempe'rature increase. 'The samples were again measured for insulation resistance and dielectric strength.

The above t.'mples'were returned to the hot cell of the Ward Nuclear 1.aboratory at Cornell University to simulate the accur:ulated exposure b

30 days from.the accident. The dose rate was 3.38X10 rads per hour for 7

.an accumul'ated dose'of 5.4X10 rads.

The total accumulated dose on the b

~

s (10) g Fi~nai

samples was 1.25GX10 rads frem the three irradiation exposures.

~

n measurements were made,of insulation resistance and dielectric strength.

The control samples Data is presented in Tables IV through XXIV.

~

were ' remeasured along with the irradiated samples.

Small changes were

~

noted, due primarily to dif ferent humidity conditions and long charging times to obtain stabilized readings.at these extremely low currents.

4 CONCLUSIONS:

While there was seme reduction in insulation resistance with increasing accumulated dose, none of the components tested' changed encugh to cause any significant degradation of performance.

Allcomponentscontiqually The passed the. dielectric stYength tests without voltage breakdown.

~

seal assumblics also remained leak tight'.throughout the radiation tests.

- All components would survive the forty' year dose plus one accident,.

I and still function in their intended application.

HAR0tlESS TESTS The ef fect of irradiation on the ha'rdness of the following items was investigated:

1.

Scotchcast Epoxy 3ti-XR5126 2.

Polysulfone c

3 Polyplate 4.

Sylgard 185 Measurements were made per ASTM 02240 with the applicable u

Shore Ourometer tester.

The data is su::narized in Table XXV,.

Polysulfona and Polyplate Scotchcast changed very IIttle in hardness due to the Irradistion.

~

Epoxy XR-5126 changed approximately 10?' in har,dness but this would not artect the intended use of the epoxy.

Sylgard 155 increased

.approximately 75% in hardness due to crosslinking during irradiation.

The material did not become brittle or lose its functionability. _

composite seal assemblies sealed with Sylgard 185 continued to be

items 1, 2, 3, 4, and 5 passed this test with no removal of the copper flim on the test slide.

Item 6, the Scotchcast Epoxy.XR 5126, lef t the copper film 70% intact.

Item 7, the Polyplate, left the copper t

Although some of the copper film was removed by items 6 and 7, the IIeli i. abs Corrosive Outgassing Test is extreaely sensitive to g

very small quantitics of gas. Also, this test uss run under the.

accident condition of 175 C.

At 93 C.(200 F) these samples passed the test. The total amount of corrosive gas evolved in the penetra-i tion from the actual amounts of items 6 and 7 used in the assembly wili have no deleterious effect on the performance of the penetrations.
