I FLORIDA POWER & LIGHT COMPANY St. Lucie Plant Unit No. 1 License No. DPR-67 Docket No. 50-335 ANNUAL ENVIRONMENTAL RADIOLOGICAL MONITORING REPORT for The Period: 1-01-79 to 12-31-79 Prepared 3-21-80 8P P4P9 0819

p K4 g

l. Introduction This report is sub@it~ in accordance with St. Lucie Plant Technical Specifications'ection 5.6.l.b.

7 All environmental samples were collected and analyzed during this report-ing pericd in accordance with require~ts of St. Lucie Plant's Technical Specifications. The minimum of frequency of collection and analyses for specific radionuclide species as required by these specifications have been met or exceeded except where samples were biologically unavailable No harmful effects or evidence of irreversible damage to the environment or to the health and safety of individuals or population groups in. the regions surrounding St. Lucie Plant have been detected by this monitoring program.

In addition to the Environmental Radiological Honitoring data, this report includes information about the semi-annual census for 500 ft2 gardens and milk-producing animals.

Strontium analyses for this reporting period have been'elayed due to the relocation of the State's Radiological Laboratory; these results will be sham in a separate report when analyses in progress are ccmpleted.-

2. The Mnitorin Program Anal 'cal Reszensibilitv Environmental radiological monitoring at St. Lucie Plant is car-ried out by the Orlando Radiological Laborator~ of the Department.

of Health and ~~abilitative Services of Florida (DHRS) personnel.

Nunber of Samples Anal ed A total of 1425 analyses were pe formed on1095szaples collected frcm 25 different san@ling locations during the period of this report. TABLE 1 sumnarizes the mean and range values of these analyses, Since 40K, 226Ra 232Th are naturally occurring radio-nuclides, no data for these species are recorded in this table.

The gross beta data reported is representative of these and other naturally occurring radionuclides.

Split S le Anal ses At least 20 of the sarrjles collected have be n analyzed in the DHRS/ERDA Split-Sample Program.

Evaluation of Data Except as noted in TABLE 1, none of the sampling locations used in the environmental radiological monitoring program showed evidence of having significant concentrations of a particular radionuclide in a specific sample material much nigher than the observed mean for that radionuclide at all s~~ . ling locations. Past, weapons testing fallout accumulations (as Sr, 95Zr, 131I, 137Cs and 4') observed at scme locations were not indicative of any effluent release by twit 1 during this operational period.

Trend plotting of our particulate and direct radiation data reveals no plant-related variations. Also, all data have been evaluated with re-spect to pre-operational data and hat== been found to'e witMn the + 2+

limits observed for these pre-operat'onal data. Carparative data obtam-ed in the assay of control samples also'ppears in TABLE l.

Da'erd, Goat, and Garden Census A dairv herd census was conducted in February and in August. during t~ais report period. The nearest dairy is west of the plant si o (260o; . 14 miles) Data obtained in the assays of samples collected at this location are reported in TABIZ l.

A':goat herd:census was conducted i'n February and in August during. this report period: The results. were; "no known goat herds in the County".

An aerial garden census in June, 1979 showed that there were several 500 ft2 g~e s with approx'y 5 miles of St. L cie Plant. T ass were sampled at Robert Canoan's, 7409 Indian River Drive: Results of these analyses appear in TABIZ 1.

5. Conclusions" During this period, the environmental radiological monitoring program has found no evidence that the operations of Plant St. Lucie Unit No. 1 contribute harmful effects or irreversible damage to either the environ-ment or to .the health and safety of individuals and population groups in the regions surrounding St. Lucie Plant.

limits obsexved for these pre-operational data. Ccaparative data obtain-ed in the assay of control samples also appears in TABES 1

4. Da'erd, Goat, and Camden Census A daixy herd census was conducted in Pebruaxy and in Auger during tMs report p riod.. The nearest dairy is west of the plant site (260o; . 14 miles) Data obtained in the assays of samples collected at this location are reported in ALE l.

A goat herd census ~ras conducted-in February and in August during. this report period.': The 'results.'<ere "no Grown goat~ds in the County".

An aerial garden census in June, 1979 shol~e9. that there vivre several 500 ft2 gardens within approv~tely 5 miles of St. Lucie Plant. Tcmatces were sampled at Robert Caxman's, 7409 Indian Riv r Drive; Results of these analyses appear in TABLE 1.

5. Conclusions During this period, the environmental radiolcgical monitoring program has found no evidence that th operations of Plant St. Lucie Wit Ão. 1 contribute haxmful effects or irreversible damage to either the or to the health and safety of individuals and population groups environ-'ent in the regions surrounding St. Lucie Plant.
