i BY GRINDING AND REWELDING. THE PIPING WAS THEN SUCCESSFULLY 4

HYDR 0 STATICALLY TESTED. NO ANALYSIS OF.THE CAUSE WAS MADE AT THIS TIME BUT IT IS ASSUMED THAT IT RESULTED FROM FATIGUE SIMILAR TO THE RECENT LER ON THE SAME PIPING (LER 82-003/01T-0). THE EVENT-

,, WAS NOT IDENTIFIED AS REPORTABLE AT THE TIME AS A CONDITION REPORT

"'WAS NOT INITIATED TO ANALYZE THE EVENT FOR REPORTABILITY . THE OPERATOR WA'S NOT AWARE OF THE SEVERITY OF THE LEAK WHICH HE HAD NOTED AS " PINHOLE". IT HAS BEEN A PLANT PRACTICE TO INITIATE A CONDITION REPORT WHEN TECHNICAL SPECIFICATION EQUIPMENT IS REMOVED FROM SERVICE FOR OTHER THAN PREVENTIVE MAINTENANCE OR~ SURVEILLANCE TESTING. TO ENSURE THAT IN.THE FUTURE REPORTABLE CONDITIONS ARE NOT MISSED, THIS PRACTICE HAS BEEN INCORPORATED INTO THE PLANT PROCEDURE ON EQUIPMENT CONTROL AND THE CHANGE.T0 Tile PROCEDURE IS BEING CIRCULATED TO ALL LICENSED PERSONNEL.
