Dear Sir. O'Reilly:
Florida Power & Light has reviewed I&E Bulletin 81-03 and has determined that:
1.
Corbicula g, (Asiatic Clam) is not present in the cooling canal waters utilized for Turkey Point Units 3 & 4. The organism is primarily a fresh water invertebrate and it is highly unlikely that it will become established in the saline, closed cycle cooling canal system that constitutes the plant's source and receiving water body used for condenser cooling.
2.
No Mytilus species have been found in the Turkey Point cooling canal system for the sampling years 1978,1979 and 1980. Mvtilus so., (Mussel) has a southern distributionallimit of approximately 20-30 miles south of Cape Hatteras, N.C.
Additionally, the Mytilus exhibits an upper temperature limit of 190 C (66.20 F) which makes the cooling canal system thermally unsuitable for its' proliferation.
The Turkey Point Plant's present benthic sampling program, consists of assays performed semi-annually at eight stations in the cooling canal system and three in l
Biscayne Bay. The last sample date was October,1980.
It is FP&L's opinior. that increased prevention and detection actions are not I
warranted at this time due to the absence of Corbicula so. and Mvtilus so. in the l
Turkey Point vicinity.
Ve[ry truly yours.
