Dear Mr. Keppler:
i SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 - DOCKET NOS. 50-327 and 50-328 - i FACILITY OPERATING LICENSES DPR 72 AND 77 - PRELIMINARY 10 CFR 21 REPORT ON ,. j SILICONE RUBBER-INSULATED CABLES '
I l'
TVA has conducted special high-potential withstand tests on a number of i installed No. 14 silicone rubber-insulated single conductor cables. As of !
this date, 9 of 66 tests of cables have not met the environmental !
qualification acceptance criteria of 240 volts per all of insulation. Cables from two of the three vendors that supplied this type of cable to TVA are involved, i
l TVA has conducted laboratory tests on' cables from each vendor and has been unable to determine the nature or cause of this condition.- However, these ;
laboratory t'ests did indicate that significant decreases in insulation wall '
thickness result from lower than espected impact forces. The level of impact force which results in such decreases may be caused by damage occurring during manufacturing, shipping, or handling. Cables from all.three vendors were j tested'in the laboratory and evidenced similar reductions in wall thickness.
1
-As'a result, a determination'has been made that this problem is reportable.
pursuant to the requirements of 10 CFR 21. As you know. I received a September 4.'1987 briefing on the potential problem. Subsequently I gave you- i a verbal report by telephone that day.. In addition, on September 5, 1987, R. L. Gridley of my staff gave a verbal report by telephone to Dr. J. Nelson-Grace, Regional Administrator of NRC Region II. ,

An extension to September 10, 1987 for submittal of.this report was discussed with and approved by you on September 9, 1987. T7A is providing this report before completion of further tests and evaluation in order to keep the NRC fully apprised of the situation.
TVA will submit a further report upon completion of the additional tests and evaluation. i l

ENCLOSURE SEQUOYAH NUCLEAR PLANT PRELIMINARY REPORT SILICONE RUBBER-INSULATED CABLES i
Nature of Defect and Cause a As a result of the nonconformances of three. silicone rubber-insulated single conductor No. 14 cables identified during special high potential tests, subsequent testing was-initiated by TVA on silicone rubber-insulated cables installed at the Sequoyah Nuclear Plant (SQN). The subsequent testing identified three additional nonconformances each of AIW Corporation and Rockbestos conductors. The sample population of Anaconda conductors did not !
1
( experience any failures. TVA has now identified a total ~of 9 nonconformances out of 66 tested conductors. To date. TVA has been unable to identify a !
I definitive cause for these nonconformances. TVA has concluded that the performance of silicone rubber-insulated cables is significantly different I than expected. In addition, the performance of silicone rubber-insulated j cables is significantly different from other cables at T7A of which 923 tests ;
were just completed with no failures. ,
~
l i
TVA authorized laboratory testing of silicone rubber-insulated cables, and I this testing indicated that significant decreases in insulation wall thickness result from lower than expected impact forces. The level of impact force which results in such decreases may be within that which could possibly occur during (1) manufacturing operations following the factory high potential withstand test. (2) handling at the manufacturer. (3) shipping, (4) receipt / storage by TVA, or (5) the installation process. TVA has, however, been unable to consistently. correlate this data to the nonconformances identified.
These cables are manufactured by American Insulated Wire (AIW) Corporation, 36 Freeman Street Pawtucket, RI 02862; Anaconda-Ericsson (Continental),
P.O. Box 1863, New Haven, York, PA' 17405; and the Rockbestos Company, P.O. Drawer 1102, C7 06504.
'}
The determination that a reportable condition may exist was reached on September 4, 1987.
Estent of Safety Hazard A nonconformance of the cable at voltages below that accepted by the industry to demonstrate insulation integrity during equipment qualification testing may indicate the inability of the cable to perform its intended function under design basis accident conditions. The inability of these cables to perform as designed could create a substantial safety harard.
Silicone rubber-insulated cables are used in low voltage power and control circuits (both safety and nonsafety related) inside the reactor containment buildings of SQN units 1.and 2.
limited applications in other areas These cables of these have two also been utilized in units.

There are approximately 252 silicone rubber-insulated cables which require j qualification under the requirements of 10CFR50.49, installed inside the i containment of SQN unit 2.
