NOTE: Measurement results having magnitudes that are significantly above the background of the measurement system are reported as net values plus or minus a one-standard-deviation error term.

Measurement results that are not significantly above background are reported as "non-detectable" (ND) or as less than a Lower Limit of Detection ((LLD), which is an estimated upper limit (with at least 95% confidence) for the true activity in the sample.

NOTE: Measurement results having magnitudes that are significantly above the background of the measurement system are reported as net values plus or minus a one-standard-deviation error term.

Measurement results that are not significantly above background are reported as "non-detectable" (ND) or as less than a Lower Limit of Detection (<LLD), which is an estimated upper limit (with at least 954 confidence) for the true activity in the sample.

NOTE: Measurement results having magnitudes that are significantly above the background of the measurement system are reported as net values plus or minus a one-standard-deviation error term.

Measurement results that are not significantly above background are reported as "non-detectable" (ND) or as less than a Lower Limit of Detection (<LLD), which is an estimated upper limit (with at least 954 confidence) for the true activity in the sample.

SUMMARY

Name of Facility St. Lucie Units 1 & 2 Docket No.(s) 50-335 and 50-389 Location of Facility St. Lucie Florida (County, State)

Reporting Period Zanua 1 - December 31 1990 NOTES,

a. The LLD is an "a priori" lower limit of detection which establishes the smallest concentration of radioactive material in a sample that will yield a net. count above system background that will be detected with 954 probability with only 5%

probability of falsely concluding that a blank observation represents a real signal.

LLDs in this column are at time of measurement. The MDAs reported in Attachment B for the individual samples have been corrected to the time of sample collection.

b. Mean and range based upon detectable measurements only.

Fraction of detectable measurements at specified locations is indicated in parentheses (f).

c. Specific identifying information for each sample location is provided in Attachment A. I

d. Results are based upon the average net response of two TLDs.

(Thermoluminescent dosimeters).

MDA refers to minimum detectable activity.

III DISCUSSION AND INTERPRETATION OP RESULTS A. Re ortin of Results The Annual Radiological Environmental Operating Report contains the summaries, interpretations and information required by the St. Lucie Plant, Units 1 & 2 Technical Specifications. Table 1 provides a summary of the measurements made for the nuclides required by Technical Specifications, Table 4.12-1, 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, Ra-228, and Be-7 which are common in the Florida environment.

1990 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST LUCIE PLANT - UNITS 1 & 2 B. Inte retation of Results

1. Direct Radiation:

The results for direct radiation monitoring are consistent with past measurements for the specified loc'ations. The exposure rate data shows 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:

The results for radioactive air =particulate and radioiodine monitoring are consistent, with past measurements and indicate no trends attributed to plant effluents. All samples for radioiodine yielded no detectable I-131. Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation. The results for air particulate/radioiodine samples are consistent with measurements which were made during the preoperational surveillance program. Air particulate and radioiodine monitoring results are summarized in Table 1.

3. Surface Water:

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

Tritium was reported as present in three of the weekly surface water samples collected from Site H-15.

Subsequent samples indicate there has been no increase nor adverse trend for tritium in surface water samples at H-15. The highest measured tritium at site H-15 was less than 14 of the reporting level specified by plant technical specifications, Table 3.12-2. No other nuclides attributed to station operation were detected.

Results for surface water samples are summarized in Table 1~

4. Naterhorne Sediment and Food Products:

The results for radioactivity measurements in waterborne sediment, fish and crustacea samples are consistent with past measurements and with measurements made during the preoperational surveillance program. Cs-137 was detected in one sample from the control location, about 10-20 miles South of the plant; the result is about 74 of the table 4.12-1 LLD and about. 0.5% of the table 3.12-2 reporting level. There were no indications of any radionuclides attributed to plant effluents. Results for the waterborne sediment, fish and crustacea samples are summarized in Table 1.

5. Broad Leaf Vegetation:

The results for radioactivity measurements in broad leaf vegetation are consistent with past measurements and with measurements made during the preoperational surveillance program. Minute quantities of Cs-137 were detected in one monthly sample at two locations. One location is close to the plant, the other is about 10-20 miles South.

The maximum value is about 354 of the table 4.12-1 LLD and about 1.44 of the table 3.12-2 reporting level.

There were no indications of any nuclides attributed to plant effluents. Results for the broad leaf vegetation samples are summarized in Table 1.

C. Conclusions The data obtained through the St. Lucie Plant Radiological Environmental Monitoring Program verifies 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. The measurements verify that the dose or dose commitment to members of the public, due to operation of St.

Lucie Units 1 &,2, during the surveillance year, are well within "as low as reasonably achievable (ALARA)" criteria established by 10 CFR 50, Appendix I.

0 1990 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT STe LUCIE PLANT - UNITS 1 & 2 I ~ INTRODUCTION This report is submitted pursuant to Specification 6.9 of St.

Lucie Unit 1 and St. Lucie Unit 2 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 1 and Unit 2 Technical Specifications.

II ~ RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. ~Pur ose 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 for the St.

Lucie Plant is conducted pursuant to Technical Specifications 3/4s12 of St. Lucie Unit 1 and St. Lucie Unit 2 Technical Specifications.

1. Sample Locations, Types and Frequencies:

a. Direct radiation gamma exposure rate is monitored continuously at 27 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 'eta, and gamma isotopic

. measurements.
