Dear Mr.. O'Reilly,
In accordance with the requirements of Section 6.12.2a of the Technical Sp~6ifications of Facility Operating License No. DPR-26, the following report is submitted.
\\
During the course of *a routine plant inspection on January 21, 1974 a small leak wa~ observed at the upstream orifice flange connection for flow transmitter 946D in the six inch residual heat removal sys-tem return line (Line No. 355) to No. 21 reactor coolant loop.
At the time of this observation, the reactor was in the cold shutdown condition with the residual heat removal system in service and pres-surized to about 400 psig.
The leak.is at the base of the fillet weld attaching a 3/4" pipe nipple to the orifice flange and is on the pipe side of the weld.
Preparations for repair.of the leak are underway~ however, before repairs are initiated, a dye penetrant inspection of the weld will be made to determine the nature and extent of the defect.
In add-ition our Engineering Department is investigating the occ~rrence in an effort to deter~ine the qause.
Mr. Anthony Fasano of your office was notified on 'January 21, 1974 of the circumstances relating to this occurrence.
