'I. INTRODUCT ION This report is submitted pursuant to Section 6.9 of the Turkey Point Plant Units 3 5 4 Technical Specifications and provides information and results for environmental sanples specified by Table 4.12-1.

Radiological environmental surveillance for the Turkey Point Plant is conducted in accordance with Section 4.12 of the plant's Technical Specifications. A summary of the smples collected and analyses performed during the period July 1, 1983 through December 31, 1983 is provided in Tabl'e 1.

1. THE MONITORING PROGRAM Period Covered: This report covers the period from July 1, 1983 through December 31, 1983.

Analytical Res onsibilit~: Environmental radiological monitoring. for the Turkey Point Plant is conducted by the State of Florida, Department of Health and Rehabilitative Services (DHRS). Sanples are collected and analyzed by DHRS personnel.

Number of San les: During the period, a total of 702 sanples were for radioactivity.

collected from 37 different locations to be analyzed Table 1 summarizes the highest, lowest and mean results for all sanple locations, and where applicable the highest, lowest and mean results for the sanple locations which yielded the highest mean levels. The values in Table 1 are based upon only those analyses which yielded detectable measurements.

~AII- I: I 8 1891 1,1983- >>,'I 3, addition to the sanples identified in Table 1, 10 smples were submitted for comparative analysis by the DOE in accordance with the DHRS/DOE split-sampling progran.

3. MISSING DATA Due to the length of time required to perform the analyses, several BgSr, gOSr results were not available for this report. Mhen completed, these results will be provided in a supplemental report. Based on past experience, the missing data is not expected to alter any of the conclusions of this report.

A description and explanation for these and other missing data is contained in Table 1.

4. DISCUSSION AND INTERPRETATION OF DATA

~Ai I I: 3 I I 3118 <<H 8 I I locations surrounding the Turkey Point Plant. Smples were collected and analyzed by Florida DHRS for gross radioactivity and radioiodines (I-131) on a weekly basis. All sanples from this reporting period were within the

" .'normal range of background measu'rements. 'able I provides a summary of these results.

Direct Radi ation Nonitorin: Continuous monitoring '5i anbfent radi ation exposure rate was provided routinely at eleven different sanple locations surrounding the Turkey Point Plant. Smples are collected and analyzed by Florida OHRS on a monthly basis. Results are based upon the average readings of two dosimeters at each location. All results from this reporting period were within the normal range of background measurements. Table 1 provides a summary of these results.

~01: t did h pt environmental samples are routinely collected from areas around the Turkey Point Nuclear Plant. These samples include precipitation, surface water, drinking water, sediment, fish, crustacea, food crops, vegetation, milk, soil and other terrestrial biota. Table 1 provides a summary of the results of these samples from July 1, 1983 through December 31, 1983.

As in the past, tritium was the predominant radionuclide to be detected in water sanples from around the Turkey Point Plant, with the highest levels found in water sanples taken from within the plant's closed cooling system. The highest tritium concentration measured during this surveillance period was only about 0.23$ of the concentration which would be permitted continously in unrestricted area waters {10CFR20, Appendix B, Table II.) The highest concentration of tritium observed in samples outside of the cl.osed cooling system was only about 0.07$ of the I

.unrestricted area concentration. Trend analyses indicate

'I no evidence of" continued buildup of tritium around the Turkey Point Plant.

In addi ti on to waterborne tri ti um, trace concentrati ons of fissi on and activation products continue to be detected in some sanples taken from within the closed cooling system. These results are consistent with past measurements and data indicate there is no discernable increase in radioactivity in these sanples.

The results of radiological measurements for other medi a and other locations surrounding the Turkey Point Plant do not yield evidence of buildup in the environment when compared to past measurements, including sanples collected during the preoperational surveillance program, and elsewhere within the State of Florida.

5. CONCLUSIONS The concentration of all radionuclides reported in Table 1 is much less than that permitted for release to unrestri cted areas as specified in 10 I

CFR 20, Appendix B, Table II. The Radiological Environmental Monitoring Progran establishes that radioactivity released as a result of operation of the Turkey Point Plant Units 3 5 4 is not contributing significantly to the radiation exposure of any individual or population group.
