CORPORATE STANDARO THERMAL - RADIATION MATERIALS APPLICATION DATA TR.44763BB Description Flame retardant glass mat reinforced polyester laminated composition.

Application: DH breakers, terminal boards, radomes, insulation barriers.

Thermal Data This item is a glass fiber reinforced polyester composite having the properties of a NEMA GPO-2 laminate. Figure 1 shows the 40 year life temperature for GPO-2 laminates as a function of the end of life criterion. If 50% retention is chosen as the end of life criterion, the 40 year life temperatures are 1250C for flexural strength and 980C for dielectric strength.

Radiation Data **

Glass polyesters are among the more radiation resistant materials.

Their resistance will vary with the ratio of glass to polyeste ard manufacturing variations. In general, radiation effects literature indicates that most glass polyesters are not signi ficantly 8 affected (4 25% change in any parameter) for doses 4$ 5 x'10 rads. A radiation effects study Sf a similar glass polyester indicates that after a dose of 10 rads, the flexural and tensile strengths have degraded <25%.

  • PHILADELPHIA. PENNSYLVANIA 19103 TEL£PHONC (215) 44S-1000 MEC1-LANICAL AND NUCLEAR ENGINEERING DEPARTMENT May 14, 1971 Mr. R. L. Korner Electronic Tube Division Westinghouse Electric Corp.

Dear Mr. Korner:

The electrical penetration which you provided was mounted on a test chamber that is used to simulate the environment that results from an accident in a nuclear power station containment building. In particular the temperature, pressure, humidity and chemical spray conditions are provided with chamber. The radiation exposure is done elsewhere.

Your electrical penetration was used to provide electric power connection for 6 simulated "loss of coolant accident." The primary test being the one for Westinghouse Nuclear Energy Systems Division, Pittsburgh. This test is documented in FIRL final report F-C2709 (Jan. 1970) which is property of Westinghouse.

The penetration was used to provide power connection for a series of tests, with your permission, before it deteriorated and had to be removed. The evaluation of material and/or equipment under test in each particular case is proprietary information of that sponser so we cannot supply you with copies of reports. However, the exposure and performance of your penetration is tallied in the table which I have compiled and attached.

Very truly yours, L. E. WITCHER Research Engineer Atch.

Clarification Of the leak rate' testing during and after exposure.

The canister tested has two seals approximately 9 feet apart. The outboard seal remains at a relatively low temperature of 107'F. As both seals are considered in determining leakage thru the penetration, the same leak rate established before the test, applies during and after the test since the outboard seal is not affected by the test.

-6 This value was found to be less than 1IX 10. std. cc/sec. (helium) prior to test and therefore applies duri ng and after the test.

The fact that the internal canister pressure 14.2 PSIG, remained at the same value before and after the test verified that the inboard seal did not leak within the limits of the accuracy of the gage reading.

6.0 JUSTIFICATION THAT THE PROTOTYPE UNIT TESTED ACTUALLY REPRESENTS THE INSTALLED EQUIPMENT The installed penetration is shown in Drawing D-E 2198 and is-the same as the specimen tested except for the following:

(1) Test specimen was 2" larger in diameter.

(2) Test specimen was 16" longer.

These deviations are inconsequential to performance. The test specimen therefore can be considered representative of the actual Indian Point No. 3 design.
