Operating experience feedback report: Analysis of occurrences caused by equipment and material problems. Deleted Version.

摘要

The Defense Program (DP) occurrence analysis reports identified problems with equipment and material directly to 30 to 40% of the occurrences in the DP facilities. These occurrences were analyzed to determine significance to safety-related systems and components. The analysis identified several safety systems and components which should be included in cycles of inspection, preventive and corrective maintenance, and assessment to mitigate their failures. 91 to 98,Y. of the occurrences at Plutonium Fabrication (PUFAB), 371 operations, 771 Operations, Analytical Operations, F canyon, H canyon, K-Reactor and L-Reactor involved safety-related systems. The frequently failed systems are the Selective Alpha Air Monitor (SAAM), Emergency Diesel Generator (EDG), Ventilation, Radiation Alarm, Safety Computer, Fire Alarm, Radioactive Waste Transportation System, Glove Box, Power Distribution, Sprinkler, and Uninterruptable Power Supply (UPS).
