ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 TAPES FOR HEAT TRACINO DO NOT MEET CHEMICAL SPECIFICATIONS BLRD-50-438/82-06, BLRD-50-439/82-06 10 CFR 50.55(e)
FIRST INTERIM REPORT
- Description of Deficiency Permacel FT-160 is a pressure sensitive tape supplied to TVA by the heat trace system vendor, Chemelex Division, Raychem Corp., Redwood City, CA.
Upon receipt, TVA evaluated PT-180 per Purchase Specification PF-4121,
" Purchase Specification for Pressure Sensitive Tapes for Use.on Stainless Steels or Other Corrosion Resistant Alloys," which establishes the total halogen content and the leachable halide content acceptable in pressure sensitive tapes that may be used on stainless steel. TVA's Singleton Materials Engineering Laboratory Report B-198 establishes that the leachable halide content of PT-180 exceeds PF-4121 guidelines.
In addition, the sulphur content of PT-180 exceeds PF-4121 guidelines, but this has been determined to be a nonsignificant condition in accordance with 10 CFR 50.55(e) guidelines because sulphur has no adverse effects on stainless steel pipe.
Purchase specification PF-4121 which is referenced above is applied only to indefinite quantity term (IQT) contracts which are administered by site personnel. However, PT-180 was supplied under a contract which was administered by Engineering Design personnel, and PF-4121 was not a part of the procurement documents. Consequently, this is not consicered a 10 CFR Part 21 nonconformance.
Interim Progress TVA is evaluating the deficiency and will supply additional information in our next report.
