P o c. 3 dvana cepa PRELIMINARY NOTIFICATION J
September 22, 1976 PRELIMINARY NOTIFICATION OF EVENT OR UNUSUAL OCCURRENCE--PNO-76-162 This preliminary notification constitutes EARLY notice of an event of 3
POSSIBLE safety or public interest significance.
The information x
/
presented is as initially received without verification or evaluation and is basically all that is known by IE staff on this date.
Facility:
Indian Point Unit No. 3 (DN-286) 23 Subj ect:
DEFECTIVE WELD ON BORON INJECTION TANK SAFE END While shutdown for a scheduled maintenance outage, a minor (weeping) leak was observed in the vicinity of a factory-made weld on the outlet nozzle of the boron injection tank.
Subsequent visual inspections and radiographs confirmed that the weld joining the pipe safe-end to the tank was defective. The defect was apparently caused by lack of weld material. A weld section is being examined in the licensee's metallurgy laboratory. The licensee has determined that a similar factory-made weld on the inlet nozzle was acceptable.
The safe-end will be removed and rewelded.
This is expected to delay the scheduled startup by 7 to 10 days.
The licensee is also determining if he has other tanks installed that were made by the same vendor (Joseph Oat and Sons, Incorporated). Region I is reviewing the generic aspects of this problem.
Media interest is expected because of close attention given to opera-tions at Indian Point. The State of New York has been informed. A press release is not planned.
Region I, NRC, Philadelphia, Pennsylvania received notification of this occurrence by telephone from the licensee's Director of Technical Engineer-ing at 3: 30 p.m., September 21, 1976.
The information is current as of 8:30 a.m., September 22, 1976.
