Doesrintlom

III Cable Trays A, C, and E were exposed to an over-temperature condition in the initial thermal aging period. During the thermal aging chamber temperature startup, the chamber temperature was inadvertently allowed to increase in excess of the temperature tolerance acceptance criteria. The out-of-specif ication temperature was determined to have been approximately 5.6 dog C above the required temperature of 112*C, for a period of less than 5 minutes. The short period of specimen exposure to the out-of-specification temperature was considered to have no effect upon the qualification program for the silicone rubber Insulated cables..

4.0 SUMMARY (Continued)

Notice of Date of AsmlyN. Anomaly Seto Descrintion

32 12-03-88 V Low resistance values recorded for Cable Tray C were documented during the pre-test wet insulation resistance mea4surements. The test chsimber was drained of water and insulation resistance measurements were repeated at certain intervals. At the Customer's .1 request. Cable Tray C was removed from the Accident Chamber and discontinued from the test program. .1 The pre-test wet insulation resistance measurements were repeated on the test specimens of Cable Trays A and E, and testing was continued.

3 12-28-88 V Power supply line voltage fluctuations and power losses resulted in test I specimen out-of-specification conditions. A conservative estimate of 5 hours '0 minutes was added to the test Iprof i i the post-DDE aging temperature of , i50F (+9, -0 deg F). The test specimens remained powered during I the additional test period.

4 12-09-88 V Out-of-specification PH levels existed for the chemical spray solution during I the Accident Simulation. The high PH level (0.15 above tolerance) occurred for approximately the last 2 hours of I the required chemical spray test. The short period of chemical spray at the high PH level was considered not to have a detrimental effect upon the test specimens' performance.

The test specimens were subjected to normal radiation exposure, thermal aging, Iand accident radiation exposure. The 40-year test specimens specified for Sequoyah Nuclear Plant demonstrated the capability to maintain specified voltage and current during the specified Design Basis Event (LOCA Simulation). I It is therefore judged that the Sequcyab Nuclear Plant 40-year silicone rubber insulated cables, described and noted in Paragraph 6.0 of this section, met the acceptance criteria requirements of Wyle Laboratories' Qualification Plan a (WLQP) 18057-00, Revision A.

1.2 Specimen Preparation and Baseline Functional Test

The test specimens, as provided by Tennessee Valley Authority (TVA), shall be mounted in open cable trays as specified in Paragraph 3.2 of Section VII. Upon completion of specimen preparation, the test specimens shall be subjected to the Baseline Functional Tests described in Paragraph 3.3 of Section VII.

2.0 PROCEDURES

2.1 Specimen Identification

A visual inspection of the test specimens was conducted upon receipt at Wyle Laboratories. This inspection was performed in order to document manufacturer and identification numbers of the specimens to be tested and any noticeable damage. In addition, all specimens were tagged with metal OTest Specimen" tags to facilitate their identification during the test program. The results of the identification inspections were recorded on the 'Test Specimen Inspection* forms in the appendices of this Section.

2.2 Test Specimen Preparation

The test specimens were removed from the TVA shipping enclosure and separated according to manufacturer type. During test specimen removal and preparation, air sampling was conducted in a secured area. The air sampling was performed to determine if excessive levels of asbestos fibers existed during specimen preparation. Results of the air samples indicated that the asbestos fiber level was within safety requirements. The test specimens were placed in open cable trays 18 inches wide and 5 feet long. Rockbestos (RWC) and Anaconda-Continental (ANA) test specimens were placed in Cable Trays A through F as delineated in the following table.

2.3.1 Visual Insisection

The test specimens were subjected to a visual inspection prior to initiation of the wet insulation resistance measurements. All observations noted during the visual inspection were recorded.

U 2.3.2 Wet Insulation Resistance Measurements

The test specimens as mounted in the cable trays were immersed in tap water with both leads of each specimen suspended out of the water. Insulation resistance measurements were taken of each cable specimen by applying 500 VDC for I minute prior to reading the resistance value between conductor and ground (the cable tray). All insulation resistance measurements were

recorded for information only.

I 3.0 RESULTS

The test specimens were subjected to the specimen identification, preparation, and Baseline Functional Tests of Paragraph 2.0 and met the requirements of Paragraph 1.0. Observations recorded during the Baseline Functional Test visual inspection are presented below.

I During the visual inspection it was noted that some of the cable specimens exhibited varying degrees of an ash discoloration on the asbestos jacket material. This discoloration of the jacket material did not seem to be Iattributable to a particular plant/age designation or manufacturer. Cable specimens that did not exhibit this discoloration were noted to maintain a dark black tone.

UPo" 00ompe101on Of irradiation. the tast specimens were subjected to a Post. Radiation Functional Teom The Functional Test was performed as described in Paragraph 2.3, Section 1. of this report.

&s0 RESULTSI

Th seast specimens were subjee to the Normal Radiation Exposure and PostRaduation Functional Test of Paragraph 2.0 sad met the requirements of Paragraph. 1.0. Photograpwhs of the seat specimens mounted in the cable trays were takren upon receipt as Wyle Laboratories. Observations recorded during the Poss-Radiasift Functional Teast Visual Inspection are presented in the3 following paragraphs.

During the visual inspection it was note that. in general, the teat specimens9 were in good condition and showed so indication of damap or severe degradation. The Tefze cable ties were iatact sand were maintaining specimen cable position on the cable trays. The test speimen separated from the metlW asurac of the cable tray(s) in some areas between the specimen cable ties. This ¶lexls of the lset specimens can be attributed to the normal radiation exposue that the specimens received, and to the natural coiling assure of the cables Visual inspectioes for each individual cable tray are presented In the3

Cable Tray A was n01ed to have Silicone insulation on the lead ends of Teat Specimens A and I that was much darker in apperance than the remaining teat Wspcimens on the tray. The asbestos braided Jacket material on Test Specimen E was found to be fraying; at the lead ends. All of the test specimens on this tray exhilbited as ask coloring on their Jacket material. The test specimens, as mounted In she cable tray, bad lestome flexibility.

Cable Tray 3 was noted to have ash coloring on the Jacket material on all ofI the test specimens, with Test Specimen D being the least apparent. The test speimes,% as mounted in hbe cable tray. had lost some flexibility. All of the teat specimens wen *NWe to bae" curved at the lead ends Is the elevated3 portion of the cable teay.

Cable Tray C was note to hae" darkened hosicoe Insulation at the lead ends3 Of Tess Specimens A sad 9. as described previously for Cable Tray A. The asbestos braided Jacket material on Test Specimens A sand a was found to be fraying 2t the lead enak All 0f Sim test speimens on this tray exhibited an ash 40oloring on the Jacket material with Test Specimens D and I being theS Neas apparent. Test specime flexibility was as described previously for Cable Tray A.
