MURPHY'S LETTER DATED JANUARY 2, 1980,
REFERENCE:
RII:LM 50-259/79-42, 50-260/79-42$
50-296/79-42 INFRACTION
, As required by 10 CFR 50, Appendix B, Criterion V, "Activities affecting qualigy shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings."
Tennessee Valley Authority's memorandu'm dated October 4, 1979,
- entitled, "Program to Resolve NRC IE Bulletin 79-14," states in part "All discrepancies not resolved by the EN DES engineer at the site will be called into the EN DES coordinator (CEB)" and the guideline used for the implementation of NRC IE Bulletin 79-14 stated in part "notify MN DES promptly regarding all possible non-conformances."
Contrary to the above, the following discrepancies were not reported to "EN DES" for proper evaluations.
1.
Three hangers in the RCIC system unit 3 were identified,.to have discrepancies with a similar installation 'in unit 2.
These discrepancies were nat reported to EN DES and Unit 2 hangers were not inspected.
2.
A horizontal support was identified on a 6" line of RCIC system in unit 1 which did not appear on the hanger drawing.
This discrepancy was not identified to EN DES and the support was not part of the original as-designed analysis.
This is in infraction.
RESPONSE
Corrective Ste s Which Have Been Taken and Results Achieved A review was made of all previous inspection data records to confirm that EN DES has been notified of all discrepancies.
The unit 2 hangers referenced in item 1 above have been inspected with minor deviations which were determined by EN DES not to be significant.
The horizontal support 4
referenced in item 2 above was reviewed by EN DES and determined not to be significant.

~
Corrective Ste s Taken to Avoid Further Noncom lienee An outage mechanical engineer is assigned at the plant t'o coordinate NRC IE Bulletin 79-14, and he is working more closely with the field inspectors in order to report deviations to EN DES promptly.
Deviations are called in to EN DES daily, followed up by copies of drawings and sketches detailing deviations when needed.
Identified deviations are tracked through disposition.
The onsite EN DES engineer is assisting the outage mechanical engineer'n reviewing and screening the inspection data, thereby increasing the promptness of reporting discrepancies to EN DES.
Date Full Com liance Achieved Full compliance was achieved on January 22,= 1980.
