1-1 SECTION 1. INTRODUCTION AND

SUMMARY

A qualification test on electric cables was performed in accordance with the suggestions contained in IEEE 323-1974, "IEEE Standard for Qualifying Class lE Equipment for Nuclear Power Generating Stations"; IEEE 383-1974, "IEEE Standard for Type Test of Class lE Electric Cables, Field Splices, and Connections for Nuclear power Generating Stations" Section 2.4; and the two super-heated steam test profiles supplied by Eaton Corporation, Samuel Moore Operations. The samples were subjected to sequential exposures of thermal aging and radiation, followed by an exposure to two environments of superheated steam. The samples were electrically energized at rated voltage and current loading during both steam cycles. This loading consisted of a potential of 600 volts (AC), between conductors and ground, and a current of 0.5 amp. Approxi-mately 10 feet of each sample was subjected to the two MSLB environ-ments. The cores of samples 10 through 13 and 20 were thermally aged for 7 days at 150 C by Eaton Corporation, Dekoron Division at their Aurora facility. After the thermal aging, the samples were jacketed and subjected to an additional aging of 7 days at 121 C. Cable sample 14 was thermally aged for 7 days at 136 C and the two single conductor samples, numbers 15 and 21, were thermally aged for 7 days at 150 C. ISOMEDIX, INC.

2-2 2.2.2 Phase II - Radiation Aging The cable samples were placed in a radiation facility and subjected to a Cobalt-60 source of gamma radiation at an exposure rate of approximately 0.56 Megarads per hour. Appendix A contains the formal radiation certification. The samples were removed after they had received an accumulated dose of 25 Megarads. At the conclusion of Phase II - Radiation Aging, insulation resistance measurements were made at room ambient conditions. 2.2.3 Phase III - MSLB Simulation, 1000 seconds (See Figures 1& 2) At the start of the superheated steam exposure, all samples were electrically energized and the ambient temperature inside the pressure vessel was raised to 235 F by the use of strip heaters. To initiate the exposure, superheated steam was rapidly admitted, raising the temperature and pressure to 430 F and 0 29 psig in 25 seconds. This temperature and pressure was maintair.ed for a period of 95 seconds. At the end of this period, a temperature and pressure drop was initiated that reduced the conditions to 210 F and 10 psig over the next 40 seconds. The temperature was theh reduced to 175 F at 10 psig over the next 840 seconds at which time the system was shut down. I 150MEDIX, INC. COMPONENT TESTi4G DMSON. 309 WATCHUNG AVENUE, WEST ORANGE NEW JERSEY 07052. (201) 736-9411

2-4 At that time, a controlled temperature and pressure 0 drop was initiated that reduced the temperature to 255 F at 15 psig over the next 200 seconds. Upon reaching 255 F, the temperature and pressure were further reduced over the next 161.35 minutes to 180 F and 10 psig. These conditions were maintained for the balance of 10 days. During the simulation, the samples were electrically energized at a potential of 600 Vac and a current load of 0.5 ampere. All the samples remained energized throughout the entire exposure period. 2.2.6 Phase VI - Post-MSLB Test (10 Day) At the conclusion of the 10-day exposure, insulation I. resistance measurements were made and the sanples were removed from the vessel. The samples were removed from the mandrel, straightened, inspected and recoiled onto a mandrel whose diameter was 40 times the cable diameter. While so coiled, the samples were immersed in water and subjected to their rated a.c. voltage, twice their rated a.c. voltage, and 80 Vac/ mil per IEEE 383 for periods of 1 minute, 1 ninute, and 5 minutes respectively. i ISOMEDIX, INC.

After the 10-day MSLB simulation. The measurements were made after application of 500 Vdc for one minuta, by reading between conductor and ground. The 600 Vac load was removed during the measurements and reapplied at the conclusion. 3.4 HIGH VOLTAGE WITHSTAND TESTS (HI-POT) At the conclusion of each of the MSLB exposure periods, the samples were removed from the vessel, straightened and coiled into a coil having a diameter 40 times the cable diameter. Each conductor of a cable sample was subjected to a potential relative to that conductor and the other conductor connected to the drain, which were at ground potential. i ISOMEDIX, INC.

Dear Mr. Green:

.s .v A ? < -j .2 Several utilities have recently made inquiries on the ' qualification t[a o E,E tests run by General Electric Company on electrical terminal blocks. g uj The interest stems from laboratory tests conducted at Franklin 4g Institute on two types of terminals. These are Marathon model number.M6012 and Westinghouse model number 542247. The equipment was evaluated for performance when exposed to pressure, temp.er.atur,e and h_um_idity conditions resulting frem a Loss o.f Coolant Accident. - The test was performed on unprotected terminal blocks defined as not installed in sealed or vented metal enclosures. The Marathon terminal block failed to survive the twenty-four hour test' duration while the WestiHghouse terminal block passed the test. . ~~ 7 Part of the GE electrical penetration qualification testing program, recently reviewed by the NRC.during a quality audit, was to evaluate the effect of the high temperature, pressure and humidity experienced during a LOCA on terminal blocks. The types of terminal blocks tested were GE type CR151 and States Company type HT. These were selected for testing since they are used in some power and control applications' that could potentially be utilized in safety circuits which would.be required to function in a LOCA environment. Terminal blocks for ' thermocouples were not included since these are not required to function during a LOCA. 0* '?.\\.:: Mg G .n.- pp1 1:. .1 '.t ..qu . > ~. \\,. 2 ,39'/ o.. / e
