ENGINEERING ANALYSIS l

1 The following explanation concerns a discrepancy identified since the February 1980 report and is provided to show the two levels of judgment used by TVA to resolve these discrepancies.

Furthermore, S

all safety-related systems will receive a final review and evaluation after the final inspection data packages are received.

Browns Ferry Unit 1 - Drywell Sump Pump Discharge Line to Radwaste Bulletin 79-14 Requirements k

The August 15, 1979, supplement to OIE Bulletin 79-14 requires that the significance of each nonconformance be determined by engineering judgment within two days followed by an analytical evaluation within 30 days.

Where either phase of the evaluation shows a potential safety problem TVA is required to meet applicable technical specification action statements including prompt reporting.

Two-Day Engineering Judgment The two-day engineering judgment cas that if support R-1, located on the drywell sump pump discharge line to cadwaste in unit 1, had been a seismically qualified support, the additional 10 missing supports on that line would not have affected containment integrity. Since R-1 was determined to be not qualified, containment integrity was judged to be in jeopardy. The February 21, 1980 report to the NRC reflected this judgment.

30-Day Analysis

• The followup analytical evaluation by TVA has confirmed the potential problem with primary containment integrity.

However, the analysis has shown the problem to be caused by one of the missing supports (No. 10), rather than R-1.

Support No. 10 is needed to limit pipe deflection that could idterfere with the operation of the containment isolation valves and support No. 10 shall be installed before startup of unit 1 from its current

- refueling outage.

• A rigorous analysis is performed within 30 days whenever the engineer has any doubt as to the validity of his two-day engineering judgment.
