SUBJECT:
THE OPERATING REACTORS EVENTS MEETING November 29, 1988 - MEETING 88-47 On November 29, 1988, an Operating Reactors Events meeting (88-47) was held to brief senior managers from NRR, AE00, OSP, Commission Staff, and Regional Offices on events which occurred since our last meeting on November 22, 1988.
The list of attendees is included as Enclosure 1.
The events discussed and the significant elements of these events are presented in Enclosure 2. Enclosure 3 presents two events suggested for long-term followup and c summiry of reactor scrams. One significant event was identified for input to NRC's performance indicator program.

NOTES
- 1. PLANT SPECIFIC DATA BASED ON INITIAL PEVIEW 0F 50.72 REPORTS FOR THE WEEK OF INTEREST. PERIOD IS MIDNIGHT SUNDAY THROUGH MIDNIGHT SUNDAY. SCRAMS ARE DEFINED AS REACTOR PROTECTIVE ACTUATIONS WHICH RESULT IN ROD MOTION, AND EXCLUDE PLANNED TESTS OR SCRAMS AS PART OF PLANNED SHUTDOWN IN ACCORDANCE WITH A PLANT PROCEDURE. THERE ARE 109 REACTORS HOLDING AN OPERATING LICENSE.
- 2. COMPLICATIONS: RECOVERY COMPLICATED BY EQUIPMENT FAILURES OR PERSONNEL ERRORS UNRELATED TO CAUSE OF SCRAM.
- 3. r RSONNEL RELATED PROBLEMS INCLUDE HUMAN ERROR, PROCEDURAL DEFICIENCIES, AND MANUAL STEAM GENERATOR LEVEL CONTROL PROBLE!!S.
4 "0THER" INCLUDES AUTOMATIC SCRAMS ATTRIBUTED TO ENVIRONMENTAL CAUSES (LIGHTNING), SYSTEM DESIGN, OR UNKNOWN CAUSE.
