MEMORANDUM T0: " FILE DISTRIBUTION:

TPAB r/t

.FROM: Stephen M. Stern, Acting Chief- . Mtg. Attendees Performance Indicator Section' EPDRF l Trends and Patterns Analysis Branch Office for Analysis and Evaluation of Operational Data

SUBJECT:

MEETING WITH INP0 ON MAY 17, 1989 Representatives of INP0 and NRC met to discuss the similarities and differences between .the INP0 and NRC Performance Indica. tor (PI) Programs.

I NRC and INP0 PI Programs track four common indicators; Automatic Scrams while Critical (SCRAM), Safety System Actuations .(SSA), Forced, Outage Rate (FOR),-

and Collective Radiation, Exposure-(CRE).

s i

The indicators. values, particularly the industry averages,. are not identical since NRC and INP0 currently'use different plant populatiob and different sources of data to compute their indicators.

Both INP0 and NRC will examine their differing thresholds for SSAs which is the major difference.between.the common indicators.

The differences'between INPO a;nd NRC FORs is due to the use of a median value 1 by INP0 and a.mean value by NRC in addition to the different population of plants for the PI program.

l The NRC PI program tracks individual events from LERs and Immediate Notifications. INP0 relies heavily on utility supplied data, subject to INPO guidelines and QA review. .

The enclosed document served as a discussion point over the differences in the INP0 and NRC indicators.

NRC discussed upcoming changes in the NRC PI program - specifically the inclusion'of INPO CRE data and the used of LER-based cause code data.

INP0 discussed the future directions for their program, specifically the international coordination of a set of indicators and the assumptions of their current Pl program. In addition, they discussed their success with their Safety System Performance Indicator.

INP0 and NRC will continue to exchange PI data.
