[en] To meet the objectives of the Department of Energy (DOE) Environment, Safety, and Health (EH), Office of Safety Compliance funded programs, the Performance Assurance Project Office (PAPO) administers an unusual occurrence reporting (UOR) system program. The policy for this effort, as set forth in DOE Order 5000.3, Unusual Occurrence Reporting System, is that unusual occurrences be promptly reported, UORs be critically reviewed, and information of generic significance be disseminated to interested DOE organizational elements. This report presents an assessment of the DOE UOR program for FY 1988 and covers only the activities of the PAPO. There were 508 UORs processed during the year and these include Initial, Initial-Final, Interim, and Final reports. There was a total of 316 occurrences; therefore, the number of UORs processed was larger than the number of occurrences. There was a 12% decrease in UORs processed relative to FY 1987. There is a continuing trend of declining numbers of reported occurrences since FY 1984, and there was a 7% decrease in the number of occurrences in FY 1988 relative to FY 1987. Five operations offices issued 88% of the occurrences. The Operation Offices are Albuquerque (AL), Chicago (CH), Idaho (ID), Oak Ridge (OR), and Richland (RL). 3 refs., 14 figs., 8 tabs
