This Special Report is being submitted pursuant to Technical Specification (TS)3.3.3.1 ACTION 28 and TS 6.9.2 to report an event in which the Post Accident Sampling System (PASS)was inoperable for a period greater than seven days.The seven-day period for returning PASS to service was exceeded at approximately 1005 MST on August 17, 1992.BACKGROUND INFORMATION'ASS is designed to sample reactor coolant and containment atmosphere under post accident conditions.
If you have any   questions, please contact Thomas R. Bradish at (602) 393-5421.
The liquid sample portion of the system provides pressurized and depressurized reactor coolant samples as required for analysis.The gas sample portion of the system provides containment atmosphere samples as required for analysis.ACTIONS TAKEN: On August 10, 1992, Palo Verde Unit 3 was in Mode 1 (power operation) when PASS was declared inoperable at approximately 1000 MST for maintenance.

Following the completion of work at approximately 1503 MST on August 10, 1992, PASS was declared operable.On September 2, 1992, Chemistry Technicians discovered that the PASS was unable to draw a vacuum on the gaseous sample bomb.Initial troubleshooting determined on September 4, 1992, that the maintenance performed on August 10, 1992, may have caused the PASS to be inoperable.
