FLORIDA POWER&LIGHT COMPANY St Lucie Plant Unit No.1 License No.-DPR-67 Docket No.50-335 MMUAL ENVIRONMENTAL RADIOLOGICAL MONITORING REPORT for The Period: 1-01-78 to 12-31-78 Prepared 3-27-79

~i'.Introduction This report is submitted in accordance with St.Lucie Plant Technical Specifications Section 5.6.1.b.All environmental samples were collected and ana3.yzed during this reporting period in accordance with requirements of St.Lucie Plant's'echnical Specifications.

The minimum of frequency of collection and analyses for specific radionuclide species as required by these specifications have been met or exceeded.No'armful 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 Environment Radiological Monitoring data, this report includes information about the semi-annual census for 500 ft~gardens and milk-producing animals.2.The Moaitorin Pro ram Anal t2.cal Res onsibilit Environmental radiological monitoring at St.Lucie Plant is.carried out by the Orlando Radio1ogical Laboratory of the.Department of Health and Rehabili-.tative Services of Florida (DHRS)personnel.

Numb'er of Sam@les.Anal zed A.total of.1,174 analyses on samples collected from 25'ifferent locations were performed during the period of this report.TABLE 1 summarizes the mean and, range values of these analyses.S lit Sam le Anal ses At least 20 of the samples collected have been analyzed in the DHRS/ERDA Split-Samp'ing Program.3.Evaluation of Data Except as noted in TABLE 1, none of the sampling locations used.m the environmenta3 radiological monitoring program showed evidence of having significant concentrations of a particular radionuclide.

in a specific sample material'uch higher than the observed mean for that radionuclide at all sampling locations.

Trend plotting of our particulate and direct radiation data reveals no plant-related variations.

A'iso, all data have been evaluated with respect to pre-operational data and have been found to be within the+2a 3.imits observed for these pre-operational data.Comparative data obtained in the assay of control samples also appears in TABLE l.

4-Non-Routine Re orted Measurements Following the March Chinese weapons test, a weekly composite of air particulate filters.and a milk sample were collected and analyzed..I was detected and appeared to be from the Chinese weapons tests.-5.Dair Herd, Goat,, and.Garden Census A dairy herd census was conducted.

in February and in August during this report-period.The nearest aairy is west of the plant site (260');14 miles)Data obtained in the assays of samples collected at.this location are reported in TABLE l.One milk goat has been found, at a location SN of the plant site (220';2.2 miles).It produces negligible amounts of milk.An aerial garden census in March,'1978 showed that there'ere several 500 ft~gardens within approximately 5 miles.of St.Lucia Plant.Collard Greens were sampled at 7609 Indian River Drive;NSH,.2 miles, Results.of these analyses.appear in ABLE l.6.Conclusions During-this period, the environmental radiological monitoring program chas found no evidence that the operations of PSL'Unit No.1 contribute harmful effects or irreversible damage to either the environment=

or to the health and safety of individuals and.population groups in the regions surrounding
