NDP: No data provided. No data'was provided to EPA for inclusion in their report.

NA: Not available. Report containing this data has not yet been received from EPA, Las Vegas.

ACTION LEVEL:

Cause: An incorrect efficiency file was used to calcu-late the results.

Corrective Action: Check the final printout from the gamma spectrometer more carefully.

(2) Cause: An incorrect date for beginning of the yttrium ingrowth was used in the calculations.

Corrective Action: Point out to the new chemist the significance of the ingrowth date and stress its importance in the calculation of the data.

(3) Cause: A short term glitch in the proportional counter produced very erroneous data.

Corrective Action: Check the proportional counter printout for obvious glitches.

II'ADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. ~Per 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'or 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 3/4.12 of St. Lucie Unit 1 and St. Lucie Unit 2 Technical Specifications.

Note: The program was not affected by Hurricane Andrew.

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 beta, and gamma isotopic measurements.

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

d. Shoreline sediment samples are collected from two 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. Samples are collected and analyzed semi-annually. Fish and invertebrate samples are analyzed by gamma isotopic measurements.

f. Broad leaf vegetation samples are collected from three locations. Samples are collected 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 St. Lucie 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.

1992 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING, REPORT ST ~ LUCIE PLANT - UNITS 1 & 2 D. Land Use Census A land use census out to a distance of 5 miles radius from the St. Lucie 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

~summam 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'ISCUSSION AND INTERPRETATION OF 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.

MP3:1/RAOEHVOP ~ PSL (3)

M 1992 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST ~ LUCIE PLANT - UNITS 1 6 2 B. Inter retation of Results Direct Radiation:

The results for direct radiation monitoring are consistent with past measurements for the specified locations. 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 four of the weekly surface water samples collected from Site H-15.

'ubsequent 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. Cobalt 58 was reported as present in two of the weekly surface water samples collected from Site H-15. The highest measured Co-58 was less than 24 of the reporting level specified by Table 3.12-2. Note that Tritium and Co-58 was not seen in the same sample. No other nuclides attributed to station operation were detected. Results for surface water samples are summarized in Table 1.

1992 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST ~ LUCIE PLANT - UNITS 1 & 2

4. Waterborne 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 reported as present in one fish sample collected at Site H-15, Atlantic Ocean beach about a mile east of the plant. The reported value is less than 104 of the Table 4.12-1 LLD, and less than 14 of the Table 3.12-2 reporting level.

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 two monthly samples at a location close to the plant.

The maximum value is, less than 40% of the table 4.12-1 LLD and is less than 24 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.

Because this result is much higher than the long-term average value of 5.0 micro-R per hour for this site, and because we know of no other reason to explain an elevated reading there, it is suspected that these dosimeters were not annealed (zeroed) when they were deployed. An estimate based, on this assumption. yielded a corrected result of 5.4 + 0.3 micro-R per hour, which would be a normal result for this site. 2.a IODINE-131 IN WEEKLY AIR FILTERS Ci m Sam le Site Collection Date H08 H12 H14 H30 H34 04-08-92 <0.02 <0.02 <0.02 <0.02 <0:02 04-14-92 <0.03 <0.03 <0.03 <0.03 <0.03 04-21-92 <0.03 <0.02 <0.02 <0.03 <0.02 04-28-92 <0.03 <0.03 <0.04 <0.03 <0.03 05-05-92 <0. 03 <0. 03 <0. 04 <0.03 <0.03 05-12-92 <0.02 <0.02 <0.02 <0.02 <0.02 05-20-92 <0.02 <0.02 <0.01 <0.02 <0.01 05-26-92 <0.02 <0.02 <0.02 <0.02 <0.02 06-01-92 <0.02 <0. 02 <0.02 <0.02 <0. 02 06-08-92 <0.02 <0.02 <0.07(A) '0.03 <0.02 06-16-92 <0.02 <0.02 <0. 02 <0.02 <0.02 06-23-92 <0.02 <0.02 <0. 02 <0.02 <0.02 06-30-92 <0.02 <0.02 <0.02 <0.02 <0.02 (A) This sample had a low collected volume due to failure of the air pump.

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. DIRECT RADIAT ON LDs micro-R hour Each result is the average net response of two dosimeters.
