EVENT.94d CAUSE: THE DIRECT CAUSE OF THIS EVENT WAS THE INADVERTENT DEPRESSURIZATION OF THE 1PT-0457 AND 1PT 0458 COMMON REFERENCE LEG DURING MAINTENANCE, WHEN THE 1PT-0457 TRANSMITTER SWUNG INTO A TUBING ISOLATION VALVE AND CAUSED IT TO OPEN. THE ROOT CAUSE OF THIS EVENT WAS A COGNITIVE PERSONNEL ERROR ON THE PART OF THE INVOLVED l&C TECHNICIAN BY NOT SUPPORTING THE TRANSMITTER DURING REMOVAL.

CORRECTIVE ACTIONS: PRESSURIZER PRESSURE TRANSMITTER 1PT-0457 WAS REPLACED AND CALIBRATED AN ENGINEERING REVIEW OF PRESSURIZER TRANSMITTER PROBLEMS IS BEING PERFORMED. A SAFETY AND LICENSING REVIEW WILL BE PERFORMED TO EVALUATE THE POSSIBLE USE OF THE TEST lN-BYPASS SYSTEM FOR CORRECTIVE MAINTENANCE ON CERTAIN INSTRUMi N rs.
