2014 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 INTRODUCTION This report is submitted pursuant to Specification 6.9.1.8 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.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. Purpose 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 to 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. Proqram Description The radiological environmental monitoring program (REMP) for the St. Lucie Plant (PSL) is conducted pursuant to the St. Lucie Units 1 and 2 Offsite Dose Calculation Manual (ODCM) Section 3/4.12.1, Monitoring Program.

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 1

2014 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS 1 & 2 analyzed by gamma isotopic measurements.

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

Note: Ground Water Protection, NEI Initiative: The program and results are described in Attachment D

2. Analytical Responsibility:

Radiological environmental monitoring for the St. Lucie Plant is conducted by the State of Florida, Department of Health (DOH), Bureau of Radiation Control (BRC).

Samples are collected and analyzed by DOH personnel.

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

C. Analytical Results Table 1, Environmental Radiological Monitoring Program Annual Summary provides a summary for all specified samples collected during the referenced surveillance period.

Deviations from the sample schedule or missing data, if any, are noted and explained in Table 1A. Samples not meeting the specified "A PRIORI" LLD, if any, are noted and explained in Table 1B. Analysis data for all specified samples analyzed during the surveillance period is provided in Attachment B.

D. Land Use Census A land use census out to a distance of a five mile 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 16 meteorological sectors. A summary of the land use census for the surveillance year is provided in Table 2, Land Use Census Summary.

E. Interlaboratory Comparison Program The interlaboratory comparison program consists of participating in the DOE Mixed Analyte Performance Evaluation Program (MAPEP).

This program provides similar testing (matrices, nuclides, and levels) as the former EPA Interlaboratory Comparison Program and is referred to as the Mixed Analyte Performance Evaluation Program (MAPEP).

The samples are analyzed using the methods applicable to the REMP (Gamma Spectroscopy, Gross Beta, and Tritium for Water).

From the MAPEP handbook:

Acceptance criteria were developed from a review of precision and accuracy data compiled by other performance evaluation programs (PEPs), the analytical methods literature, from several MAPEP pilot studies, and from what is considered reasonable, acceptable, and achievable for routine analyses among the more experienced laboratories.

2014 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 II1. DISCUSSION AND INTERPRETATION OF RESULTS A. Reporting of Results The Annual Radiological Environmental Operating Report contains the summaries, interpretations and information required by St. Lucie Plant ODCM. Table 1 provides a summary of the measurements made for the nuclides required by ODCM, 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, and Be-7, which are common in the Florida environment.

B. Interpretation of Results

1. Direct Radiation: The results of direct radiation monitoring are consistent with past measurements for the specified locations. The exposure rate data shows no indication of any adverse trends attributed to effluents from the plant. The measured exposure rates are consistent with exposure rates that were observed during the pre-operational surveillance program.

A condition report has been generated to evaluate a potential downward trend in Direct Exposure TLD Readings over the past several years in the PSL Site Radiological Environmental Monitoring Program (REMP). The PSL Site REMP Coordinator is working with the State of Florida Bureau of Radiation Control and the other two nuclear sites, Turkey Point and Crystal River to evaluate ifthere is a potential trend and any possible causes of the trend.

Direct radiation monitoring results are summarized in Table 1 and are trended in Figure on next page.

2. Air Particulates/Radioiodine:

For results attributed to plant effluents: 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 1-131. Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation. The results for air particulate/radioiodine samples are consistent with measurements that were made during the pre-operational surveillance program. Air particulate and radioiodine monitoring results are summarized in Table 1 and are trended in Figure 2 below.

3. Waterborne, Surface Water:

The results for radioactivity measurements in surface water are consistent with past measurements and with measurements made during the pre-operational surveillance program. Tritium was reported as present in one of the 52 indicator locations and none of the 12 control location surface water samples collected. The highest value was 2.5% of the required LLD listed in ODCM Table 4.12-1. There were no indications of any other nuclides that could be attributed to plant effluents.

Results for surface water samples are summarized in Table 1.

4. Waterborne, Sediment and Food Products:

The results for radioactivity measurements in waterborne sediment, fish, and crustacean samples are consistent with past measurements and with measurements made during the pre-operational surveillance program. There were no indications of any nuclides attributed to plant effluents. Results for the waterborne sediment, fish and crustacean 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 pre-operational surveillance program. There were no indications of any nuclides attributed to plant effluents. Results for broad leaf vegetation samples are summarized in Table 1.

6. Land Use Census:

There were no additions or changes to the Land Use Census as compared to last year's report.

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 percent greater than locations currently being sampled in the radiological environmental monitoring program were identified by the land use census.

7. Interlaboratory Comparison Program:

The State of Florida laboratory participated in MAPEP 30 and 31. These satisfied the requirements as directed in the PSL Offsite Dose Calculation Manual (ODCM) for the Interlaboratory Comparison Program.

The results are listed in Attachment C.

2014 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 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 measured exposure rates are consistent with exposure rates that were observed during the pre-operational surveillance program.

• The results for air particulate/radioiodine samples are consistent with measurements that were made during the pre-operational surveillance program.

" The highest value of tritium in surface water was 2.5% of the required LLD listed in ODCM Table 4.12-1. There were no indications of any other nuclides that could be attributed to plant effluents.

" There were no indications of any nuclides in waterborne sediment or food products attributed to plant effluents.

• There were no indications of any nuclides in broad leaf vegetation attributed to plant effluents.

The measurements verify that the dose or dose commitment to members of the public, due to operation of St. Lucie Units 1 and 2, during the surveillance year, are well within "as low as reasonably achievable" (ALARA) criteria established by 10 CFR 50, Appendix I.

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 95% 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.

d. Results were based upon the average net response of three elements in a TLD (thermoluminescent dosimeter).

MDA refers to minimum detectable activity.

2014 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 TABLE 1A DEVIATIONS / MISSING DATA There were several instances of missing data and air sampler partial run times as follows:

A) Direct Radiation Exposure Location: TLD: Location SSE-5 Dates: 1/1/14 - 3/31/14 Deviation: TLD data lost during quarterly processing Description of Problem: TLD data was lost during BRC quarterly TLD processing for the ODCM required TLD located 5 miles SSE of the PSL Nuclear Plant. The BRC TLD software program read data came back with a System Read Error 16 during TLD processing. Due to this read error, data for the TLD was unretrievable.

Corrective Action: The BRC worked with their State of Florida TLD software vendor "Doctor's Software" for troubleshooting and resolution of the issue. The BRC completed installation of the shorter data cable and installation of a software "patch" and the problem has not reoccurred.

All other TLD locations analyzed for the quarter were within their normal range.

B) Direct Radiation Exposure Location: TLD: Location WNW-10 Dates: 10/1/14- 12/31/14 Deviation: TLD Missing and Lost at TLD: Location WNW-1 0 Description of Problem: REMP Program TLD was missing and lost at REMP Program sampling location WNW-10. The TLD was attached to a State of Florida BRC Labeled Utility Box cluster which was removed and missing due to construction and road widening work on SR 70.

Corrective Action: The BRC deployed a new TLD/cricket cage nearby but outside of the construction work area on a chain link fence.

All other TLD locations analyzed for the quarter were within their normal range.

There was one relevant data flag:

• 1) Cs-1 34 for RdV Vegetation showed a "Warning" Flag for a result which met the MAPEP acceptance criteria but with a bias -20.1%. The previous interlaboratory crosscheck, MAPEP 29 did not show a "Warning" flag for this isotope nuclide-matrix combination and this is the first "Warning" flag for this isotope. The State of Florida Bureau of Radiation Control explained that the MAPEP vegetation nuclear analyses unknown is counted in a different geometry than used for normal nuclear REMP program vegetation isotopic analyses. The MAPEP unknown is analyzed using a smaller container, considerably smaller sample mass and different density than is used for normal, routine power plant vegetation sample counts.

There was one relevant data flag for MAPEP 31:

• 1) Cs-134 for RdV Vegetation showed a "Warning" Flag for a result within the MAPEP acceptance criteria but with a bias +21.8%. The previous interlaboratory crosscheck, MAPEP 30 also showed a "Warning" point within the acceptance criteria but with a bias of -20.1%.

There have been two in a row "Warning" flags for this isotope nuclide-matrix combination. The State of Florida Bureau of Radiation Control explained that the MAPEP vegetation nuclear analyses unknown is counted in a different geometry than used for normal nuclear REMP program vegetation isotopic analyses. The MAPEP unknown is analyzed using a smaller container, considerably smaller sample mass and different density than is used for normal, routine power plant vegetation sample counts. The PSL Site REMP Program Coordinator will continue to monitor crosscheck results for repeated "Warning" flags for Cs-134 for RdV Vegetation over the next couple of MAPEP interlaboratory crosscheck comparison program results.

2014 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 A. Description of Program:

Quarterly sampling &analysis for Tritium & principle gamma emitters is performed by the State of Florida Department of Health (DOH) and Bureau of Radiation Control (BRC),

pursuant to an Agreement between FPL and DOH, as part of the ODCM REMP sampling program.

The wells identified for radiological environmental sampling in support of the industry initiative are listed below, and in Appendix B-2 of the ODCM. The ten wells are on the

'outside' perimeter of the protected area. Two locations where the Plant ID ends with "S" are shallower wells adjacent, within a few feet, of a deeper well at the same location.
