FCLE and PECc presented ovcrviews of the types of data they have been able to collect. The data presented by PECo for the Limerick plant showed no tin;e perioc;s when more than one component was reinoved from service. Howt u r, the ' data presented Ly TG&E show d several instances where multiple component outages i.ed occurred. The diffetcnces in the results shown by the two utilities is perhaps inoicative of the cifferent types of information used to gertrate the catt. The PECo data was based on the renc ui from service of trains 01 systelas f ound-tn contribute to plent risk as determined by the Limcrick PRA. The types of equipment included in the PG&E data were more r extensise and included data for components that may not have been inoperable E (but were removed frora service) and compor.chts that apparently could have been f returned to service quickly if needed. The existence of the multiple component l' outages in one set of data, Lnd the number of such outage combinations, support the desirability of a. living-PRA, quasi real-tin;e risk model. The p differences in the data collection methods used need to be analyzed to I determine whether the data differences are due to plant-specific differences .or if the scope of the data collection at each plant was responsible for the -data differences. If the differences in the data collection methods and the spectrura of data collected are the reasons for the differences, the definition of the appropribte cata to be included in a quasi real-tine risk-based set of j Technical Specifications will have to be determined in the pilot study. Additional efforts beins pursued to incorporate risk perspectives into Technical Specificntions were also discussed at the n.eeting. PG&E presenteo (in cenjunction with Westinchouse) a proposal to evaluate the concept of flex specs, specific Technical Specifications with pre-planned risk-based alternatives.

s A 4 - E'- November 7,1989 l I The afternoon was reserved for a presentation of the PSM by EPRI. Although directed primarily toward evaluating plant availability, the PSM has several l 1 cepabilities of interest to the Risk-Based Technical Specification Working Group. - Among.these is the on-line capability to monitor system, train,. and component availability. A routine for evaluating _the Technical Specification status of the plant zis built into the system. It identifies the applicable LCO conditions in force for the current plant configuration and for projected . configurations. On a system by system basis the PSN is able to recalculate the impact on system availabilities of change in component status. The PSM contains models for several systems not normally explicitly modelled in a PRA that may need to be modelled in a Technical Specification model. Additionally, PSM models these systems for all operating n' odes, r.ot just power operation. L Our next working group meeting is tentatively scheduled for mid-January 1990. t By then we should have received input from all participating utilities on the proposed risk-based criteria and the costs associated witi. the implenientation of.the pilot program.
