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.

t.i~

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.
