INTERIM REPORT OF SIGNIFICANT CONSTRUCTION DEFICIENCY NO. 107

" SCHEDULE 80, 1" AND 2" CARBON STEEL PIPE / FITTINGS 'P3'"

INTRODUCTION This report is submitted pursuant to 10CFR50.55(e). It describes 1" and 2" carbon steel pipe / fittings in ASME Section III Class III installation which lack adequate material traceability.

To the best of our knowledge, this deficiency has not been reported to the USNRC pursuant to 10CFR21.

DESCRIPTION Documentation review of installation packages identified the lack of trace-ability for 1" carbon steel (C.S.) SCHEDULE 80 pipe and 1" and 2" carbon steel 3000# fittings on three level stations (AC system) for Chilled Water Expansion Tanks A, B, and A/B and on one level station (CC system) of the Component Cooling Surge Tank. Forty-two items have been identified as having indeter-minate traceability.

SAFETY IMPLICATIONS The piping and fittings in question connect CCW surge tank level monitoring equipment which automatically actuates makeup from the Demineralized Water System, automatically bypasses dry cooling towers and isolates the respective CCW train on low level in the respective tank side. The piping and fittings associated with Chilled Water Expansion Tanks A, B, and A/B connect level switches which automatically control makeup water supplied from the CCW makeup pumps. Portions of the CCW System and the Essential Services Chilled Water System are required to function following a design bases accident.

Therefore, if left uncorrected, the safe operation of the plant could be advecsely affected.

CORRECTIVE ACTION The forty-two items in question will be removed, scrapped, and replaced per engineering disposition on Nonconformance Reports. Completion of corrective action is anticipated by May 15, 1984.

A Final Report will be submitted to the NRC on or before hsy 30, 1984.
