_ ear 5 irs I filed on OctoberThis letter represents an addendum to the 10C 15, 1992 following are related concerns to be included:in record in your of The 1}- ?PL Management vilated Emergency Procedures to previously documented violations of technical swe ifi, in addit and Design Bases during its response to hurricane Andrew.

mode 4 winds at the site.
Unit 4. however, did not reach mode 4 until ce 4:05 AM on 8/24/92 At 5:50 AM the National Hurricane Center in Coral Cables recorded a one minute average wind speed 140. M FM.

Mr. Gene contaminated / radioactive cable was removed ou esented a formal illegally with oossibly criminal intents to sell this mat to scrao yards for recycling.
Mr. Hutchison has stated to erial
- he press that security at Turkey Point is defective from the inside out.
Palm Beach Post reported the enclosed story, soon arter Andrew, of cables being stolen from a " compound in Cade County south of the city...that was danaged by hurricane Andrew Florida City ",and the selling of 1544 counds of wire to a metal recycling center (scrap natal yard) in Lel

failures ocurred as well in both units' redunda and 4A. 4A was ineacacitaded for at least 3 minutes due to rround isolation croblems (11: 57 to 12: 00 on 8/24/92). This into doubt not just the overall reliability of the diesels, but f W/O(, M M

2-Addendun to 10CFR2.206 ?IR 10/21/92 also specific aspects of systemic vulnerability such as weaknesses of the ground detection and isolation mechanisms and instrumentation for many Turkey Point systems including RHR, Safeguards, OMS,etc.
The NRC is aware of this problem.
Again, on 8/27/92 the 3A EEG was lost due to alleged generator lockout.
h)-Page 3 of the FFL cresentation in sucport of the meeting /92 between FPL Management and NRC held on 9/10/92 (letter, 9/17 E.W. Merschoff) states " Radiation Monitoring Stack-Instrumentation 1
and minor stack foundation damage". Radiolorical Assessment teams were not sent out until 8:01 on 8/24/92. Was possible radiological exposure not monitorable, or inadequately monitorable durina a significant time period?
- 5) In the licht of the rear response by the nuclear units at Turkey Point to hurricane andrew events, and cost-hurricane startup attemets that failed with further viol &tionssof'. technical specifications, which have been documented, should the adequacy of the desiFn bases and technical specifications of Turkey Point be re-evaluated to assure the maintenance of an adequate margin of safety.?
6)- Turkey Point nuclear units are unique throughout the Nation in sharig common features and systems with its adjacent fossil units.
This interdecendence has been decreased throu6hout the years, but still entails the sharing of a common geographical, physical location.
The experience of Hurricane Andrew indicated potential vulnerabilities caused by this interaction.
For example, the collaese of boiler stacks, the collapse of oil tanks being ruptured,etc.
Mas the potential for accidents in the Fossil side, or the non-safety side of the nuclear units adversely affecting the containment structures or any nuclear safety related systems been properly evaluated in the I
light of this new experience?
