FLORIDA POWER G LIGHT COMPANY St. Lucie Plant Unit No. 1 ',

License No. - DPR-67 Docket Vio. 50-335 ANNUAL .EViVZRONHENTAL RADZOLOGZCAL HONZTORZViG REPORT for The Period: 1-01-77 to 12-31-77 Pre!ared 2-28-78

Introduction This report is submitted in accordance with St. Lucie Plant Technical Specifications'ection 5.6.1.b.

All environmental samples were collected and analyzed during this reporting period in accordance with require-ments of St.. Lucie Plant's Technical Specifications. The minimum frequency of collection and analyses for specific radionuclide species as required by these speci ications nave been met or exceeded.

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.

Xn addition to the Envi onmental Radiological i4Ionitoring data, this report includes information about the semi-annual census for 500 ft gardens and milk-producing animals.

The Nonitorin Pro ram Anal tical Res onsibilit Environmental radiological monitoring at St. Lucie Plant is carried out by the Orlando Radiological Laboratory of the Department of Health and Rehabili-tative Services of Florida (DHRS) personnel.

Number of Sam les Anal zed

..A "<otal,:of 1,594--analyses on:aamp3.es coll cted from 25 different locations were perrormed during tne period of this report. TABLE 1 summarizes the mean and range values of these analyses.

S lit Sample Analyses At least 20 of the samples collected have been analyzed in the DHRS/ERDA Split-Sampling 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 concent at'ons of a particular radionuclide in a. spec'fic sample material much higher than the observed mean =or that radionucl'de at all sampling locations. inst of the data reported

reflect concentration increases as a result of fallout from the Chinese bomb tests of 1977.

Trend plotting or" our particulate and direct radiation data reveals no plant'-related variations. Also, all data have been evaluated with respect to pre-operational data and have been found to be within the +2a limits observed for these pze-operational data. Comparative data obtained in the assay of control samples also appears in TABLE 1.

Non-Routine Reported measurements Following the release of water from the Refueling Rater Storage Tank (RNST) to the Settling Basin (on site) on 4-12-77, a series of special samples were collected from the Indian River; the ocean east of the intake canal; the ocean east of the discharge canal; a well at a residence on indian River Drive, west of the plant; and a sample of soil alongside Highway AlA, east of the plant.

These samples were analyzed by DHRS and the analytical results showed "no detectable" radionuclides of those that could have been associated with the RWST release.

Following the September-October Chinese weapons tests, air particulate filters from 3 sampling locations and a milk sample were collected and analyzed.

'Ce, 'Ru, and were detected and appeared to be from the Chinese weapons tests.

Dair Herd, Goat, and Garden Census A dairy herd census was conducted in January and in August during this report period. The nearest dairy is west of the plant site (260'; 14 miles). Data obtained in the assays of samples collected at this location are reported in TABLE 1.

One milk goat has been found at a location SVT oz the plant site (220'; 2. 2 miles) . Xt produces negligible amounts of milk.

An aerial garden census in April, 1977 showed that there were several 500 ft~ gardens within approximately 5 miles of St. Lucie Plant. Collard Greens were sampled at 7609 indian River Drive; NSW, 2 m'les. Results of these analyses appea in TABLE l.

Conc'lusions During this period, tne environmental radiological monitoring program has found that the radiation levels around St. Lucie Unit No. 1 aze much less than those which might 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 St. Lucie plant.
