SUMMARY

DESCRIPTION OF THE RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM The analytical results of the Crystal River Unit 3 (CR-3) operational Radiological Environmental Monitoring Program (REMP) for 2012 are contained in this report. The operational program began on January 1, 1977 just prior to initial criticality, which was achieved on January 14, 1977.

Sampling of the facility environs is performed by the State of Florida Department of Health, Bureau of Radiation Control. The State also performs the required analyses, participates in the Interlaboratory Comparison Program, and performs the annual land-use census. Prior to 1990, the program was split between the Department of Health and the University of Florida. The transition to the State performing all of the program's sampling and analyses in 1990 is evident in several of the trend graphs, most notably oysters and carnivorous fish, and is due to the State using less sensitive measurement techniques for several of the pathways which were formerly evaluated by the University of Florida.

Sample station locations are given in Table I-1 and Figures 1-2, 1-3, 1-4, and 1-5. Sample frequency and analysis type may be determined from Table 1-2. Figure I-1 illustrates the relevant exposure pathways.

Regarding waterborne pathways, the groundwater area of the Crystal River site is too saline to be used as a source of drinking water, hence there is no credible drinking water uptake pathway. Additionally, the Florida aquifer groundwater flows in a west-southwest direction across the site toward the Gulf of Mexico and since the locale of the site is along the coast, there is no downstream public impact regarding groundwater.

Except for air sample gross beta results and direct radiation measurements, most of the analytical results are below the lower limit of detection (LLD) of the sample. Sample LLDs are generally much lower than the required "a priori" LLD. When measurable results are reported, the values are also usually less than the required "a priori" LLD.

In 2011 there were positively measured results of iodine and cesium airborne concentrations during the period of March 22 through April 12 th for almost all sampling stations including the control station. These measurements are a direct result of the earthquake and tsunami event at the Dai-lchi, Fukushima following the March 11, 2011 Tohoku event in Japan. These measurements are not related to Crystal River Unit 3 activities. The Japanese event also affected broad leaf vegetation sample media throughout the year as long-lived radionuclides (Cs-1 37) were released at Fukushima multiple times. The vegetation measurements in 2012 are still affected by the Fukushima event due to the long-lived radionuclides deposited.

The results of the 2012 REMP have been compared to previous years' results. This comparison, in part illustrated by the trend graphs of Section IV,shows no evidence of consistent long-term increasing trends in any of the sample media. However, radioactive material is routinely quantified in sediment samples which are taken in the discharge canal near the liquid release discharge point. In general, these results verify the effectiveness of in-plant measures for controlling radioactive releases.

Trend graphs illustrate the mean measured concentration of a particular radionuclide for the year. When measurable results are not obtained, the highest sample LLD is plotted. LLD and measured values are plotted on the same line to best illustrate any trend. As shown on each graph's legend, any measured value is noted by a text box, unless all values trended are measured values for that particular parameter.

Statistical summary pages are provided for each medium or pathway. Measured values are reported in terms of a mean and range. In addition, the number of measured values versus samples obtained is reported. For example, in the following entry; 15 (249/256)

(4- 35) the "All Indicator Locations" column would be interpreted as indicating a mean measured value of 15, with measured values ranging from 4 to 35. (249/256) means that out of 256 samples, 249 were measured values.

IV-A. AIRBORNE PATHWAY Air samples are taken at five locations in the vicinity of the plant. The control location is 78 miles ESE of the plant, at the Department of Health, State Bureau of Radiation Control in Orlando.

Table IV-A.1 provides a statistical summary of the analytical results for 312 gross beta samples and 312 iodine samples.

Tables IV-A.2 and IV-A.3 provide the results for each weekly air sample.

In 2012, three hundred twelve particulate samples were analyzed for gross beta activity, all of which had measurable activity. The average indicator concentration was 18 pCi/1 000 m3 with a range of 6 to 44 pCi/1000 mi3 . The average indicator concentration since 1996 was in the range of 14 to 20 pCi/1 000 M3 . The control location concentration for 2012 averaged 17 pCi/1 000 M3 , with a range of 9 to 36 pCi/1000 M3 .

In 2012, three hundred twelve samples were analyzed for iodine activity, with none having measurable activity.

The highest iodine LLD was 0.04 pCi/m 3. There were no anomalies with the iodine samples for the year.

Quarterly composite data are summarized in Table IV-A.4. In 2012, measurable quantities of cesium were not identified in any particulate filter sample. The highest cesium LLD was 1.7 pCi/1 000 m3 for cesium 134.

The 2012 airborne sample data is comparable with previous year's sample data with exception of samples collected in 2011 during the March and April time frame where airborne particulate and iodine samples were affected by the Fukushima earthquake and tsunami event that occurred on March 11, 2011. Those sample data were thoroughly discussed in the 2011 Annual Radiological Environmental Operating Report submitted for Crystal River Unit 3.

There were no instances of non-collected airborne samples for the year 2012, but there were several instances of air sampler partial run times as follows:

1. In July station C-07 was down for 18.4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months due to a failed vacuum pump.

2. In August station C-07 was down for 66.7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months due to a power outage as a result of a failed lightening arrestor.

3. In September station C-1 8 was down for 41.2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months due to a failed vacuum pump.

4. In December station C-18 was down for 25.7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months due to an unknown power outage.

The remaining 4 sample stations were in service 100% of the time, with exception of filter changes and air pump/gas meter replacements. The percentages of down times for the 2 stations are as follows:

C07 0.97%

C18 0.76%

The air sample station's down times are documented in the plant Corrective Action Program (CAP) under Condition Reports (CRs) 557809 and 561970.

These run times are below the threshold reporting criteria of 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months of continuous lost run time during a sample period.

IV-B. DIRECT RADIATION Direct radiation measurements (using TLDs) were taken at seventeen locations (stations C60 through C73 and station C27) within one mile of the plant, at fifteen locations ranging from 2.8 to 6.3 miles from the plant, and at one control location 78 miles from the site. One-hundred and thirty-two TLDs were collected during 2012.

Table IV-B provides a statistical summary of the analytical results for 132 TLDs sampled throughout the year.

Table IV-B. 1 provides the results of the individual TLD measurements.

The highest on-site dose was 72 mrem/yr at station C71 (WNW at 3600 feet). Station C71 was relocated in 1992 due to construction of the helper cooling towers on the former site. The new location has a higher background radiation level due to being closer to the storage pond for Units 4 & 5 fly ash, which produces a higher external radiation component than normal levels of natural background. The second highest on-site dose was 56 mrem/yr at station C65 (ESE at 1584 feet).

The highest off-site dose was 51 mrem/yr at station C40 (east at 3.5 miles). The control station (C47) average dose was 51 mrem/yr. The average for all stations (except control) was 41 mrem/yr for 2012, 46 mrem/yr for 2011, and 49 mrem/yr for 2010. Direct radiation results are similar to previous years and show no change of significance.

There were no missing or unanalyzed TLDs during this evaluation period.

IV-C. WATERBORNE PATHWAY To evaluate the waterborne pathway, samples are taken of seawater, ground water, drinking water, and shoreline sediment.

1. Monthly seawater grab samples are taken at two locations in the discharge canal (C14G and C14H) and at one control location (Cl 3) near the mouth of the intake canal.

In 2012, of twenty-four indicator samples, six had measurable tritium at an average concentration of 125 pCi/L, with a range of 118 to 152 pCi/L. The sample with the highest concentration of tritium was obtained in December at station C14H near the beginning of the discharge canal. The seawater tritium activity is consistent with the concentration of tritium in the liquid waste stream and the release times of waste tanks.

CR-3 was in Refuel 16 outage at the time of sampling with reduced dilution due to no circulating water pumps running. Plant raw water pumps were providing the dilution flow. In 2012 three control station samples had measurable tritium concentrations at an average of 107 pCi/l.

In 2011, five of twenty four indicator samples contained measurable tritium with an average concentration of 190 pCi/L. The 2011 control station samples had measurable tritium concentrations at an average of168 pCi/L.

Gamma spectral analysis was performed on thirty-six samples, none of which showed measurable amounts of the gamma emitters of interest.

Table IV-C. 1 provides a statistical summary of the seawater tritium and gamma spectroscopy results.

Table IV-C.1 .a provides the results of the monthly samples.

2. Semiannual ground water samples are taken at one location, station C40, located approximately 3.5 miles east of CR-3. Gamma spectral and tritium analyses are performed on both samples.

In 2012, all results were less than the detection limits. Since plant startup, all results, except for the results of one 1985 tritium analysis, have been less than LLD. The required sensitivity for measuring tritium in ground water is 2000 pCi/L. Analysis of ground water in the vicinity of CR-3 is done at a sensitivity of approximately 150 pCi/L for tritium and less than 10 pCi/L for select gamma emitters. Additionally, Potassium-40, a natural product, was detected in the first sample collected in 2012. In the second sample collected, K-40 was <LLD.

Table IV-C.2 provides a statistical summary of the groundwater tritium and gamma spectroscopy results.

Table IV-C.2.a provides the results of the semi-annual samples.

3. Quarterly site ground water samples are taken at nine locations surrounding the perimeter of the CR-3 protected area. Periodically five of these ground water wells have shown indications of very low levels of tritium on the west-southwest side of the plant. It is believed that this tritium is the result of a leak in the Station Drain Tank (SDT-1) to the settling pond discharge line that occurred in 1998. This discharge line has recently been leak tested and it is leak free. There are no other know leaking plant components.

In 2012 the wells that have shown measurable amounts of tritium range from 72 to 619 pCi/L. These wells have been sampled additionally on a monthly basis to develop trend data. This increased sampling information is shown as supplemental data. Along with these wells, two other wells that are not presently part of the REMP have been sampled that are on either side of the plant settling ponds (percolation ponds).

In 2012 these two wells are showing measurable amounts of tritium in the range of 95 to 182 pCi/L, which are a result of plant discharges from the SDT-1. These discharges are being minimized through operational focus. The positively measured tritium values are below the reporting criteria of the ODCM and the NEI 07-07 Ground Water Protection Initiative Guidelines. There have been no measurable amounts of gamma emitting radionuclides in any of these wells. There have been no measurable amounts of hard-to-detect (HTD) radionuclides in any of these wells with exception of trace levels of gross alpha, which is expected, given the naturally occurring limestone strata that surrounds the Florida aquifer. It should be noted that site ground water flows in a west-southwest direction toward the Gulf of Mexico. This flow was re-verified in 2006 with a new ground water flow study performed by a certified hydro-geologist as part of the NEI Ground Water Protection Initiative. In 2012 another groundwater flow study was performed to evaluate groundwater flow post installation of CR Units 4 & 5 clean air scrubber system. This scrubber system utilizes significant groundwater from the Florida aquifer. The flow study confirmed that the groundwater flow, and direction of flow, has not been altered due to the installation and operation of the clean air scrubber system.

IV-C. WATERBORNE PATHWAY Cont'd Additionally, the groundwater at the CR3 site is too saline for use as a potable water source, hence there is no drinking water uptake pathway at the Crystal River site.

Table IV-C.3. provides a statistical summary of the groundwater tritium and gamma spectroscopy results.

Table IV-C.3.a.1 provides the results of the quarterly samples.

Table IV-C.3.a.2 provides the results of the monthly supplemental samples.

4. Monthly non-REMP required well samples were collected as discussed in item #3 above. Two wells were sampled. These two wells are located on the north side and the south side of the site percolation ponds.

The information is discussed above. Both of these wells showed no measurable amounts of any other radionuclides of interest. The tritium concentration in these wells, discussed in item #3 above, have decreased significantly due to a focused reduction in the number of discharges from the station drain tank (SDT-1) to the site settling ponds (percolation ponds).

Table IV-C.4 provides a statistical summary of the groundwater tritium and gamma spectroscopy results.

Table IV-C.4.a. provides the results of the monthly supplemental non-REMP required samples.

5. Quarterly drinking water samples are drawn from three locations: the Crystal River City Hall (C07), the Days Inn Motel (C10), and the Yankeetown City Well (C18). All samples were collected and analyzed for gamma emitters and tritium.

In 2012, none of the samples yielded measurable activities of tritium or the required gamma emitters. The measurement sensitivity for drinking water samples are the same as those for ground water samples. Note that one sample collected at station C07 yielded a statistically positive-measured tritium concentration of 77 pCi/L, which is well below the LLD of 150 pCi/L. This sample set (all three stations) was split with an independent lab to run tritium analyses. The independent lab tritium results of all three samples indicated

<LLD of 150 pCi/L. It is felt that the one sample measurement of 77 pCi/L is an outlier and is of no consequence.

Since the beginning of sampling, the drinking water samples have not had any other positive-measured radionuclides of interest detected.

Table IV-C.5 provides a statistical summary of the drinking water tritium and gamma spectroscopy results.

Table IV-C.5.a provides the results of the quarterly samples.

6. Semiannual shoreline sediment samples are taken at three indicator locations in the discharge canal (C14H, C14M, C14G) and one control location (C09) at Fort Island Gulf Beach. The plant discharge canal is the primary liquid effluent release pathway from CR-3.

In 2012, of the six indicator samples, three had measurable amounts of cesium-137 with an average concentration of 28 pCi/kg and a range of 19 to 35 pCi/kg and three had measurable amounts of cobalt-60 with a concentration range of 14 to 24 pCi/kg.

In 2011 two samples had measurable amounts of cesium-1 37 with an average of 26 pCi/kg and a range of 14 to 37 pCi/kg. Also there were three samples with measurable amounts of cobalt-60 with a concentration range of 11 to 65 pCi/kg.

In 2010 the average cesium-137 concentration at the indicator locations was 19 pCi/kg.

In 2009, the average cesium-1 37 concentration at the indicator locations was 24 pCi/kg.

In 2008, the average cesium-1 37 concentration at the indicator locations was 25 pCi/kg.

The average cobalt-60 concentration at the indicator locations ranged from 30 to 389 pCi/kg from 1998 through 2007.

The 2012 results are similar to previous years' results. None of the samples taken at Fort Island Gulf Beach, the control location station C09, indicated measurable amounts of cobalt or cesium.

Table IV-C.6 provides a statistical summary of the shoreline sediment gamma spectroscopy results.

Table IV-C.6.a provides the results of the semi-annual samples.

7. Additional samples taken in 2012 but not required by the ODCM:

Annual sediment samples were collected at four locations in the site settling ponds. Cs-1 37 was detected in two of the four samples in concentrations ranging from 10 to 16 pCi/kg. There were no measurable amounts of Co-60 or Cs-1 34 in any of the samples.

Annual surface water samples were collected at two locations in the site settling ponds. The tritium concentration was < LLD of 152 pCi/L in three of four samples. One sample in the northeast quadrant has a measurable amount of tritium at a concentration of 233 pCi/L. All of the samples showed no measurable amounts of any other radionuclides of interest. Note that two of the four surface water samples were collected in January of 2013 due to the settling ponds being drained for maintenance in December of 2012.

Table IV-C.7 provides the results of the settling pond samples.

8. There were no unmonitored spills or releases of radioactive material in 2012 that could have the potential to contaminate the ground water per the guidelines of the Nuclear Energy Institute Ground Water Protection Initiative - Final Guidance Document 07-07. As such, there were no communiques issued to state, local, or regulatory agencies.

IV-D. INGESTION PATHWAY To evaluate the ingestion pathway, samples are taken of fish, oysters, broad leaf vegetation, citrus, and watermelon.

1. Quarterly carnivorous fish samples were taken at two locations: C29 at the end of the discharge canal, and C30, the control location, near the mouth of the intake canal.

In 2012, none of the required radionuclides were found in measurable quantities. The highest cesium-1 37 LLD for station C29 was 32 pCi/kg. Naturally occurring potassium-40 was quantified in all eight samples at an average concentration of 2659 pCi/kg.

In 2011, none of the radionuclides of interest were identified in measurable quantities.

In 2010, none of the radionuclides of interest were identified in measurable quantities.

In 2009, none of the radionuclides of interest were identified in measurable quantities.

Table IV-D.1 provides a statistical summary of the carnivorous fish gamma spectroscopy results.

Table IV-D.1 .a provides the results of the quarterly samples.

2. Quarterly oyster samples were taken at the same locations as fish samples, C29 and C30.

In 2012, of the isotopes required to be evaluated, one sample from station C29 indicated measurable amounts of cesium-1 37 at a concentration of 22 pCi/L. This value was statistically positive, but is in the range of the analytical LLD. Additionally, silver-11Om was not quantified in any sample.

In 2011, silver-i 1Om was quantified in two samples at C29 with an average concentration of 19 pCi/kg and a range of 14 to 23 pCi/kg. There were no other radionuclides of interest identified in any oyster samples in 2011.

In 2010, silver-1 I Om was not quantified in any oyster samples collected. There were no other radionuclides of interest identified in any oyster samples in 2010.

In 2009, silver-i 1Om was quantified in one sample at location C29 near the end of the discharge canal, at a concentration of 20 pCi/kg. There were no other radionuclides of interest identified in any oyster samples in 2009.

Table IV-D.2 provides a statistical summary of the oyster gamma spectroscopy results.

Table IV-D.2.a provides the results of the quarterly samples.

3. Monthly broad leaf vegetation samples were taken at two indicator locations, C48A and C48B, and one control location, C47.

In 2012, thirteen of twenty four indicator samples had measurable amounts of cesium-1 37 with an average concentration of 86 pCi/kg and a range of 18 to 172 pCi/kg. The control station (C47) located in Orlando, Fl. also had measurable amounts of cesium-1 37. In eight of twelve control station samples there were measurable amounts of cesium-1 37 at an average concentration of 57 pCi/kg and a range of 16 to 201 pCi/kg. The cesium-137 values are similar in concentration as compared to samples collected in 2011 which experienced radionuclide deposition as a result of the Fukushima earthquake event and are not a result of the operation of CR3.

In 2011, eighteen of twenty four indicator samples had measurable amounts of cesium-1 37 with an average concentration of 76 pCi/kg and a range of 6 to 233 pCi/kg. Two of twenty four indicator samples also had measurable amounts of iodine-1 31 with an average of 232 pCi/kg and a range of 195-269 pCi/kg. The control station also had measurable amounts of iodine-131 and cesium-1 37.

In seven of twenty one control station samples, there was measurable 1-131 at an average concentration of 324 pCi/kg and a range of 13-1397 pCi/kg. In seventeen of twenty one control station samples there was measurable cesium-1 37 at an average concentration of 61 pCi/kg and a range of 7 to 182 pCi/kg. Nine extra control samples were collected at the Orlando station location.

68

These positive-measured radionuclides were a result of the Fukushima earthquake and tsunami event that occurred in 2011 and were not from the operation of CR3.

In 2010, five of twenty-four indicator samples had measurable amounts of cesium-1 37 with an average concentration of 66 pCi/kg and a range of 9 to 153 pCi/kg. This is higher than the levels found in 2009, but lower than in 2007 and 2008. It is believed the 2007 and 2008 spike was due to possible collection of wire grass mixed into the sample, which has a greater uptake rate of cesium as compared to other broad-leafed media. Additionally in 2010, eight of twelve control station samples had measurable amounts of cesium-1 37 with an average concentration of 21 pCi/kg and a range of 9 to 31 pCi/kg. During 2009 due to construction activities at the Crystal River Unit 4 & 5 site, the area where broad leaf vegetation was being collected at station C48A was removed. A new location in the same north sector was located near the air sample station C46. During 2010, also due to construction activities at the Crystal River Units 4 & 5 site, the area where broadleaf vegetation was being collected at station C48B became inaccessible. A new location in the ENE sector was located near the transmission power line corridor right of way, just NE of the mariculture center. This sector has the same D/Q value as the N and NNE sectors and is allowed by the ODCM.

Table IV-D.3 provides a statistical summary of the broad leaf vegetation gamma spectroscopy results.

Table IV-D.3.a provides the results of the monthly samples.

4. In 2012 one watermelon sample was collected at station C04. This sample had no measurable quantities of radionuclides of interest. Citrus samples were taken at station C1 9. There were no measurable quantities of radionuclides of interest in the citrus samples.

In 2011 two watermelon samples were collected at station C04. One sample had a measurable amount of cesium-1 37 at a concentration of 14 pCi/kg. All other radionuclides of interest were

< LLD. Citrus samples were taken at station C19. There were no measurable quantities of radionuclides of interest in the citrus samples.

In 2010 watermelon samples were collected at station C04. None of the required radionuclides were found in measurable quantities. Citrus samples were taken at station C19. None of the required radionuclides were found in measurable quantities in the citrus samples with exception of Cs-1 37 at a concentration of 71 pCi/kg.

In 2008 and again in 2009, there were no watermelon samples available at station C04. In these 2 years, due to crop rotation, there were no locally grown watermelons found in any areas nearby the facility and no local commercial harvest performed.

Table IV-D.4 provides a statistical summary of the watermelon and citrus gamma spectroscopy results.

Table IV-D.4.a provides the results of the semi-annual samples.
