1995 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT - UNITS 3 Ec 4 EXECUTIVE

SUMMARY

The data obtained through the Turkey Point Radiological Environmental Monitoring Program verifies that the levels of radiation and concentrations of radioactive materials in environmental samples are not increasing. These measurements verify that the dose or dose commitment to members of the public, due to operation of Turkey Point Units 3 6 4, during the surveillance year, is well within the limits established by 10 CFR 50, Appendix I. The sampling period was from January 1, 1995 to December 31, 1995.

Additionally, supplemental samples collected by the State of Florida, HRS, do not indicate adverse trends in the radiological environment.

1995 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT - UNITS 3 & 4 INTRODUCTION This report is submitted pursuant to Specification 6.9 of Turkey Point Units 3 & 4 Technical Specifications. The Annual Radiological Environmental Operating Report provides information, summaries and analytical results pertaining to the Radiological Environmental Monitoring Program for the calendar year indicated.

This report covers surveillance activities meeting the requirements of Unit 3 and Unit 4 Technical Specifications.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. ~Pur use The purpose of the Radiological Environmental Monitoring Program is to provide representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures of members of the public resulting from station operation. The Radiological Environmental Monitoring Program also supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.

B. Pro ram Descri tion The Radiological Environmental Monitoring Program (REMP) for the Turkey Point Plant is conducted pursuant to Technical Specifications 3/4.12 of Turkey Point Unit 3 E 4 Technical Specifications.

1. Sample Locations, Types and Frequencies:

a. Direct radiation gamma exposure rate is monitored continuously at 21 locations by thermoluminescent dosimeters (TLDs). TLDs are collected and analyzed quarterly.

b. Airborne radioiodine and particulate samplers are operated continuously at five locations. Samples are collected and analyzed weekly. Analyses include Iodine-131, gross beta, and gamma isotopic measurements.

0 1995 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT - UNITS 3 8c 4

c. Surface water samples are collected from three locations. Samples are collected and analyzed monthly. Analyses include gamma isotopic and tritium measurements.

d. Shoreline sediment samples are collected from three locations coinciding with the locations for surface water samples. Samples are collected and analyzed semi-annually. Sediment samples are analyzed by gamma isotopic measurements.

e. Fish and invertebrate samples are collected from two locations coinciding with two of the locations for surface water samples. Samples are collected and analyzed semi-annually. Fish and invertebrate samples are analyzed by gamma isotopic measurements.

f. Broad leaf vegetation samplescollected are collected from three locations. Samples are and analyzed monthly. Broad leaf vegetation samples are analyzed by gamma isotopic measurements.

Attachment A provides specific information pertaining to sample locations, types and frequencies.

2. Analytical Responsibility:

Radiological environmental monitoring for the Turkey Point Plant is conducted by the State of Florida, Department of Health and Rehabilitative Services (HRS).

Samples are collected and analyzed by HRS personnel.

Samples are analyzed at the HRS Environmental Radiation Control Laboratory in Orlando, Florida.

CD Anal tical Results Table 1, Environmental Radicle ical Monitorin Procrram Annual ~Summar provides a summary for all specified samples collected during the referenced surveillance period.

Deviations from the sample schedule, missing data and/or samples not meeting the specified "A PRIORI" LLD, if any, are noted and explained in Tables 1A and 1B respectively.

Analysis data for all specified samples analyzed during the surveillance period is provided in Attachment B.

1995 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT - UNITS 3 & 4 D. Land Use Census A land use census out to a distance of 5 miles radius from the Turkey Point Plant is conducted annually to determine the location of the nearest milk animal, residence, and garden producing broad leaf vegetation, in each of the sixteen meteorological sectors. A summary of the land use census for the surveillance year is provided in Table 2, Land Use Census

~Summaz No locations yielding a calculated dose or dose commitment greater than the values currently being calculated were identified by the land use census.

No locations yielding a calculated dose or dose commitment (via the same exposure pathway) 20% greater than locations currently being sampled in the radiological environmental monitoring program were identified by the land use census.

E. Interlaborator Com arison Pro ram The State of Florida HRS Environmental Radiation Control Laboratory participates in the Environmental Radioactivity Laboratory Intercomparison Studies Program conducted by the Environmental Protection Agency. Results from the Interlaboratory Comparison Program are provided in Attachment C.

III. DISCUSSION AND INTERPRETATION OF RESULTS A. Re ortin of Results The Annual Radiological Environmental Operating Report contains the summaries, interpretations and information required by the Turkey Point Units 3 6, 4 Technical Specifications. Table 1 provides' summary of the measurements made for the nuclides required by Technical Specifications, Table 3.12-2, for all samples specified by Table 3.12-1. In addition, summaries are provided for other nuclides identified in the specified samples, including those not related to station operation. These include nuclides such as K-40, Th-232, Ra-226, and Be-7 which are common in the Florida environment.

1995 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT - UNITS 3 & 4 B. Inter retation of Results

1. Direct Radiation:

The results of direct radiation monitoring are consistent with past measurements for the specified locations. The exposure rate data show no indication of any trends attributed to effluents from the plant. The measured exposure rates are consistent with exposure rates that were observed during the preoperational surveillance program. Direct radiation monitoring results are summarized in Table 1.

2. Air Particulates/Radioiodine:

Results of gross beta measurement are consistent with past measurements. No radioiodine was detected. The only identified isotopes are cosmic-ray produced Be-7 and naturally occuring K-40 and Pb-210 at levels consistent with past measurements.

3. Waterborne, Surface Water:

The results of radioactivity measurements in surface water samples are consistent with past measurements.

Tritium was reported as present in the surface water samples collected from site T-81. These results are consistent with the known subsurface interchange that occurs between the closed cooling canal and its surrounding waters, and the pressure gradients caused by the flow of aquifer subsurface waters in South Florida.

The highest reported tritium is less than 2% of the reporting value specified by Technical Specifications, Table 3.12-2.

4. Waterborne, Sediment:

The results are consistent with past measurements; only naturally occurring radionuclides were detected.

5. Waterborne, Food Products:

The results are consistent with past measurements; only naturally occurring radionuclides were detected.

1995 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT - UNITS 3 Sc 4

6. Broad Leaf Vegetation:

The results of radioactivity measurements are consistent with past measurements. Cs-137 was detected, as in the past, in samples collected from the indicator locations.

The maximum value is about 35% of the Table 3.12-2 reporting level, the average value is about 7% of the reporting level. No other fission products were detected.

C. Conclusions The data obtained through the Turkey Point Plant Radiological Environmental Monitoring Program verify that the levels of radiation and concentrations of radioactive materials in environmental samples, representing the highest potential exposure pathways to members of the public, are not being increased.

Additionally, supplemental to the Technical Specifications, sampling of the direct exposure, inhalation, and ingestion pathways, performed by HRS, does not show adverse trends in levels of radiation and radioactive materials in unrestricted areas. The measurements verify that the dose or dose commitment to members of the public, due to operation of Turkey Point Units 3 8 4, during the surveillance year, are" well within "as low as reasonably achievable (ALMS) criteria established by 10 CFR 50, Appendix X.

VNITED STATES ENVIRONMENTALPROTECTION AGENCY NATIONALEXPOSURE RESEARCH LABORATORY

. P.O. BOX 93478 i LAS VEGAS, NV 89193.3478 OFFICE OF RESEARCH AND DEVELOPMENT A note regarding the Gross Alpha portion of the October 27, 1995 Gross Alpha-Beta in Water Performance Evaluation Study:

Both the July 1995 and October 1995 Gross Alpha-Beta in Water Performance Evaluation (PE) Studies showed a significant difference between the grand average and the known value for the gross alpha. This strongly implies there is bias in the method.

Our research indicates that matrix differences between the salt solids used to prepare the calibration curve and the salts in the sample are the source of the bias.

The attached figure illustrates the changes in efficiency due to salt composition and nuclide energy. The bottom curve was prepared with serial dilutions of laboratory tap water. Laboratory tap water is also used to add variable amounts of dissolved solids to the

'E gross alpha/beta study samples. The second curve was prepared with serial dilutions of sodium sulfate solution. The top curve was prepared the same way as the second curve

.except that Am-241 was used as the alpha emitter. All the usual precautions apply. The curves reflect the efficiencies for our counter; the curves in the figure are illustrative only; and lastly, results for your laboratory may be different than shown in the figure.

At zero mass all the curves converge to the extent that the bias would not be noticeable in a PE study. As the mass of solids increases, the difference between the two Th-230 curves becomes pronounced. For sample masses between 30 and 40 mg, typical range for a 200 mL sample of the July 1995 or October 1995 study, the difference is between 50 to 70 percent.

To address the bias, we are recommending the procedure used in our laboratory. To a

'olume of sample equal to that used for analysis (100-150 mL) add 120 pCi of Th-230.

Acidify the sample with 20-40 mL of concentrated nitric acid and evaporate by the procedure attached to the PE study report sheet. The volume of PE,sample provided is sufficient to prepare triplicate 150 mL samples and duplicate spiked samples. Count the spikes until approximately 1600 counts above background are acquired to a maximum of 200 minutes. Background in this case will be that of the PE samples. Subtract the average count rate of the triplicate samples from the average count rate of the spikes and calculate the efficiency. Use this efficiency to calculate the concentration of gross alpha in the PE sample.

A'n alternate procedure. After counting the triplicates, redissolve/reslurry the solids of two of the samples in the planchet with dilute nitric acid (3-6M). Add the spike, mix well, redry and count the spikes. This technique, though simple on the surface, requires sufficient care so as not to lose sample volume, and that the Th-230 is thoroughly incorporated into the dissolved salts. We recommend this only for laboratories with a high degree of confidence in the analyst's ability to prepare the spikes by this technique.

You may use more or less spiked activity ifyou choose. The recommended activity of the spike and the maximum count time were determined to provide 5 percent precision at 95 percent confidence for the spike at an efficiency as low as 3 percent. For higher efficiencies the count time will be much shorter than 200 minutes. Additionally, we recommend several practice runs to gain experience with the technique you choose.

So, why not send out our laboratory tap water and have the participating laboratories prepare a curve? The tap water supplied to our laboratory varies in dissolved salt composition. This was observed during our verification of the July 1995 PE sample. Our QC samples showed a 40 percent bias when samples and spikes were quantified using a calibration curve. Repeat measurements demonstrated the bias was consistent and not due to analyst error. Therefore, preparing a curve with water from our laboratory does not guarantee that the bias will be eliminated.

Collectively these procedures are single point calibration techniques and are not prohibited by the approved methods. The curve concept was introduced in recognition of the variable dissolved solids of water in given geographical areas.
