R:pstt No. PEl-TR-870200-02 Page No. 1 I INTRODUCTION 1.0 objective The ob jec tive of the test program was tv demonstrate the operability of Limitorque control and power wiring and Okonite tape splices , when subjected to a simulated steam accident and functional sisulation. The test was performed per Procedure ptI-11t-870200-01 presented in Appendix 1.
2.0 Equipment Description The test as sembly simulated control and power wiring inside Limitorque_ valve ac t uat or s . The test assembly consisted of two circuit loops inside a NEMA-4 enclosure. The test specimens were assembled by Cooper Nuclear Station (CWS) personnel and were then 9 sent to Patel Engineers where the specimens were installed into the NEMA-4 enclosure. The enclosu re simulated the timitorque'
~~
housings at CNS. The test assemblies were f abricated per Figure g 1 of Appendix I.
o- The two circuit loops were labeled Loop 1 and Loop 2. Loop 1 contained two segments of Limitorque switch (control) wire (black
( braid), naturally aged during 12 years of service at CNS. Loop 2 contained two segments of Limitorque motor (power) lead wire (yellow braid), naturally aged during 12 years of service at CNS.
s Circuit Loops 1 and 2 each contained - three bolted Okonite T35/T95 tape splices. The lead wires used for Loops 1 and 2 wore
- Rockbestos Firewall SIS 16 AWG 600V Nuclear Cables. Per CNS, the Okonite splices were assembled by CNS personnel in accordance N with CNS Procedure 7.3.26.

111.3.1 Visual Inspection This visual inspection is documented in Appendix III. Upon removing the NEMA-4 enclosu re from the test chamber, no visual damage was noticed in Circuit Loop 1. Examination of Circuit Loop 2 revealed the cause of the low IR me asu rement s . Wire Specimen "C" (see Appendix 1. Figure 1) was frayed, exposing the conductor. Discoloration of the enclosures ' inner surf ace was visible in the area where the frayed wiring was touching the enclosu re wall. This indic ates that arcing had taken place during the testing. Wire Specimen "B" (see Appendix I, Figure 1) appeared - to be damaged siallarly to Specimen "C" but damage was not as extensive.
Further testing of Circuit Loop 2 revealed that when Specimen "C" was separated from the enclosure wall, the IR remained the same, indicating another leakage point. When Specimen "C" was pressed g agains t the enclosu re well, the IR went to 0, dead short. And when Specimens "B" and "C" were both separated from the enclosure- *
- wells, the IR increased to 40 megohne (Appendix III).
O A surf ace layer of water was noticed in the bottom of the NEMA-4 enc losu re . Through evaluation of data and other observations , it' O is believed the NEMA-4 enclosure was completely submerged during some portion in the test. This is evidenced by the drop in 4- temperature, below the required 230'F at 91 hou rs , 58 minutes into the test (see Appendix II, page 25 of 25).

CONCLUSIONS The Limitorque control and power wiring and Okonite tape splices we re subjec t ed to accident testing as described in PEI-TR-870200-01 ( Appendix The naturally aged Limit or que control wiring (Circuit Loop 1)
I).
succes s fully met the functional requirements defined bs Appendix I.
Lenkage cu rrent remained below 2 milliamps durin g the entire steam exposu re . The udnimum Insulation Resistance measured was 30-40 megohns.
Circuit Loop 1 remained continuously energized at 120 VAC during accident testing.
Fai. lure of the naturally aged Limitorque power wiring (Circuit Loop 2) to neut the defined functional requirements was the result of an interruption in the cable insulation due to unknown causes.
