SUBJECT:

INP0/NRC MEETING ON THE EQUIPMENT PERFORMANCE AND l I

INFORMATION EXCHANGE (EPIX) SYSTEM On October 22, 1996, Tom McHenry, Department Manager, Equipment Performance, I RO, updated NRC on INP0's plans for the Equipment Performance Information and Exchange (EPIX) System. The meeting handouts and list of the participants are attached. Changes in their plans for EPIX include the following:

The scope of EPIX has been revised to a three-tier approach, i.e., three levels of components and information reporting:

Maintenance rule mission important components, on which functional failure root cause information will be provided, NPRDS application coded components in the maintenance rule risk-significant systems (about 300-800 components), on which information on functional failure root cause and failure rates (number of failures per number of components per time period) will be provided, and NPRDS application coded components within the SSPI systems (30 to 100 components), on which functional failure root cause, functional failure rate, and SSPI reliability information will be provided.

• In addition to the archived NPRDS records, the general EPIX database, and the focused information (special databases to support specific data I needs), the system will have a fourth module, Info-link, an E-mail or /)

BBS for exchange of information among EPIX users. , ,

• The implementation schedule has been accelerated as follows:

Early 1997 - issue interim EPIX software (This would include the functional failure root cause and failure rate information for the maintenance rule components but not the SSPI WANO information, the

].10043 focused information, NPRDS archive and Info-lin .) Utilities begin collecting EPIX data. p jj_ ,

9611140195 961112 PDR ORG NEXD h-/ X [ y~ 2 5 ~ 7 4 b

Mid 1997 - discontinue reporting and archive NPRDS information.

January 1998 - final EPIX implementation (including SSPI WANO information).

.The EPIX system will only provide the reliability data contained in the INP0/WAN0 SSPI program and one time estimated demands and run hours for maintenance rule risk-signific. ant systems. For the remaining components in the EPIX scope, no reliability type information will be collected. The system is still in the planning stage. We will continue to actively follow the plans and development of EPIX.

But, it must:

Be simale -

- User friendly ,f

- Require minimal training -

- Yield repeatable results  %. s ~ _ ,

Be cheap

'l f x '~~.

- Use minimal human resources \'

- Use common software & hardware

- Be flexible to support changing industry needs

- Have an optimized scope

- Focused list of components

- High overlap

General principles Needs to consider plant reliability as well as safety Supports risk-informed management decisions Good compatibility between EPIX, maintenance rule, and SSPI
