INTRODUCTION This report is submitted pursuant to'ection 6.9 of the Turkey Point Plant 3 5 4 Technical Speci fications and provides information and results for environmental samples specified by Table 4.12-1.
Radiological environmental surveillance for the Turkey Point Plant is conducted in accordance with Section 4.12 of the pl ant's Technical Specifications.
A summary of the sanples collected and analyses per formed r
during the period January 1,
1984 through June 30, 1984 is provided in Table 1.
1.
THf MONITORING PROGRAM, Period Covered:
This report covers the period from January 1,
1984 through June 30, 1984.
Anal tical Res onsibilit:
Radiological environmental monitoring for the Turkey Point Plant is conducted by the State of Florida, Department of Health and Rehabilitative Services (DHRS).
Samples are collected and analyzed by DHRS personnel.
Number of Sam les:
During the period, a total of 696 samples were collected from 46 different locations to be analyzed for radioactivity.
Table 1 summarizes the highest, lowest and mean results for all sample locations, and where applicable the highest,.lowest and mean results for the sample locations which yielded the highest mean levels.
The values in Table 1 are based upon only those analyses which yielded detectable measurements.
~ll-1:

i
.184-J 30.
addition to the sanples identified in Table 1, fourteen (14) smples were submitted for comparative analysis by the DOE in accordance with the DHRS/DOE spli t-sanpling progr an.
3.
MISSING DATA A description and explanation for missing data is contained in Table 1.
4.
DISCUSSION AND INTERPRETATION OF DATA locations surrounding the Turkey Point Plant.
Sanples were collected and analyzed by Florida DHRS for gross radioactivity and radioiodines (I-131) on a weekly basis.
All samples from this reporting period were within the normal range for background measurements.
Table 1 provides a summary of these results.
Direct Radi ation Monitorin:
Continuous monitoring of ambient radi ation exposure rate was provided routinely at eleven different sample locations surrounding the Turkey Point Pl ant.
Samples were collected and analyzed by Florida DHRS 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 for background measurements.
Table 1 provides a summary of these results.

environmental sanples are routinely collected from areas around the Turkey Point Nuclear Plant.
These sanples 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 January 1,
1984 through June 30, 1984.
As in the past, tritium was the predominant radionuclide to be detected in water samples 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 0.19$ of the concentration which would be permitted continously in unrestricted area waters (10CFR20, Appendix B,
~
Table II.)
The highest concentration of tritium. observed in water samples outside of the closed cooling system was only about 0.01$ of the unrestricted area concentration.
Trend analyses indicate that there is no evidence of a continued buildup of tritium around the Turkey Poi'nt Plant.
In addition to waterborne tritium, trace concentrations of fission and activation products continue to be detected in some of the sanples taken from within the closed cooling system.
These results are consistent with past measurements and data indicate no discernable increase in radioactivity in these samples.
The results of radiological measurements, for other media and other locations surrounding the Turkey Point Plant do not yield evidence of buildup in the environment when compared to past measurements, including samples collected during the preoperational surveillance
- progran, and elsewhere within the State of Florida.
5.
SUMMARY
AND CONCLUSIONS Continuous air sanpling measurements are all within the normal
- range, for b ackg round v al ues.
Continuous anbient radi ation exposure rate measurements are all within the normal range for background values.
Tritium concentrations in water 'sanples collected around the Turkey Point Plant are consistent with past measurements.
The highest observed tritium concentr ations are found within the pl ant's closed cooling system.
All measurements are well below the concentration permitted by 10CFR20 for unrestricted area waters.
Radioactivity measured in sediment and biota samples taken from within the closed cooling system (inside the owner controlled area) is consistent with past measurements, with no discernable increase noted.
Measurements for other media and sanples are consistent with past measurements including those taken during the preoperational surveillance progr an.
The conc'entration of all radionuclides reported in Table 1 is much less than that permitted for release to unrestricted areas as specified in 10 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 to any
'member of the public.
