UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION ATOMIC SAFETY AND LICENSING APPEAL BOARD Michael C. Farrar, Chairman Richard S.

Salzman Dr.

W. Reed Johnson

@79, P qy54~~

In the Matter of FLORIDA POWER AND LIGHT COMPANY (St. Lucie Nuclear Power Plant, Unit No. 2.)

Docket No. 50-389 INTERVENORS INTERROGATORIES 'TO FLORIDA POWER AND LIGHT CO.

1.

How may system wide power failures or major electrical blackouts have occurred in the FPL system during the past 10 years?

For purposes of evaluation, please list any electric system disruptions that were either system wide, were considered major outages, consisted of so many scattered blackouts in close time sequence that constituted a substantial system disruption, involved tripping off line of one or more power generating stations in the FPL system, or resulted in the failure of on site power to any FPL generating plant.

Please provide the date of the occurance or sequence of occurances, the duration of the outage and the location of the affected areas.

2.

(Interrogatory

/f2 treats off site power failures with emphases on their effect on FPL power generating plants.)

Please list all electric blackouts or power failures in the past ten years that caused an interruption in the flow of offsite power to any FPL electric generating plant site, whether operational at the time or under construction, repair, or in cold shutdown or standby condition.

Identify with particularity, the date of the occurance, the identity of the plant so affected, the duration of the outage and the scope of the power failure in the FPL system as related to outage at the other FPL plants

3.

Please state, why, in its efforts to achieve greater system reliability the Florida Power and Light Company fails to provide a 500 kv intertie or greater to the Georgia Power Corporation and the eastern United States electrical grid system.

Would such an intertie or system of interties provide greater system reliability in the FPL system?

If not why not?

4.

Would provision of the 500 kv intertie to the Eastern U.S. electrical grid obviate the need for any additional generating capacity in the FPL system.

If the answer is affirmative, in increments of 250 kv per interties, how many megawatts of base load generating capacity in the FPL system would be obviated or a 250 kv interties, a 500 kv interties, a 750 kv interties?

5.

The testimony of NRC Staff witness R. Fizpatrick indicates the startup record of auxilliary diesel generators to provide emergency on site power at the St. Lucie Unit 1 Power Plant is sub-standard.

What reasons are known to the FPL Company for the existance of this sub-standard startup record.

To what extent does the plants proximity to the oceanic mareine environment affect the performance reliability of these diesel generators and what if any protective or remedial measures are being taken by the utility company?

6.

While Hurricane David approached South-Florida, Charles

Scheer, FPL corporate spokesman is reported in the press to. have stated "the Company would continue to operate the plants during a hurrican".

(See Palm Beach Post,

Thursday, August 30, 1979 P.

C 2).

Yet, during the pre-down hours-as the hurricane approached, the Hutchinson Island site, FPL personnel decided to shut down the St. Lucie Unit 1 reactor.

Why did this discrepancy in FPL point of view exist.

Has the company changed orestablished policy such that it will shut down reactors during hurricanes?

What is the FPL policy concerning reactor operation during passage of a major hurricane where landfall is projected to be in close proximity to the plant site?

Specifically, why did the company shut down St. Lucie Unit 1 during the passage of hurricane David?

t t

7. It is reported in the Palm Beach Post of Sept.

1, 1979, that during the passage of hurricane David at the St. Lucie site on Hutchinson Island, a construction crane segment toppled from the Unit 2 containment building and knocked out Unit 1's lead-in auxiliar transformer line.

What are the implications of this event as relates to plant safety and availability of on site power?

8.

Please provide the test results and performance records of the St. Lucie Unit 1 auxiliary diesel generators for start-up reliability up to the present date.

Please provide results originating rom the first in-service date and notate all relavent date.
