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 2006 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, -3, and -4. Sample frequency and analysis type may be determined from Table 1-2. Figure I-1 illustrates the relevant exposure pathways.
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.
The results of the 2006 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, the following entry 15 (249/256)
(4- 35) in 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 State Bureau of Radiation Control in Orlando.
Table IV-A. 1 provides a statistical summary of the analytical results for 318 gross beta samples and 312 iodine samples.
Tables IV-A.2 and IV-A.3 provide the results for each weekly air sample.
Three hundred eighteen particulate samples were analyzed for gross beta activity, all of which had measurable activity.
The average indicator concentration was 19 pCi/1000 m3 with a range of 4 to 41 pCi/1000 m3. The average indicator concentration since 1996 was in the range of 15 to 19 pCi/1000 m3. The control location concentration for 2006 averaged 18 pCi/1000 in 3 , with a range of 4 to 35 pCi/1000 in 3 .
Three hundred and twelve samples were analyzed for iodine activity, with none having measurable activity.
Quarterly composite data are summarized in Table IV-A.4. Measurable quantities of cesium were not identified. The 3
highest cesium LLD was 2.3 pCi/1000 mi for cesium 134.
There were no missed, lost, or non-collected samples for the year 2006. There were no air sample stations that had any appreciable down time. All 6 sample stations were in service 100% of the time, with exception of filter changes and air pump/gas meter replacements.

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 2006.
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 102 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 65 mremlyr at station C65 (ESE at 1740 feet).
The highest off-site dose was 58 mrem/yr at station C40 (east at 3.5 miles). The control station (C47) dose was 49 mrem/yr.
The average for all stations (except control) was 53 mrem/yr for 2006, 54 mrem/yr for 2005, and 58 mrem/yr for 2004.
Direct radiation results are similar to previous years and show no change of significance.

- o 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 (Cl4G and C14H) and at one control location (C 13) near the mouth of the intake canal. Of twenty-four indicator samples, two had measurable tritium at an average concentration of 445pCi/L as compared to eleven measurable samples containing tritium with an average of 1067 pCi/L in 2005. The sample with the highest concentration of tritium, 689 pCi/L, was obtained in December at station C14G near the mouth 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. Two control station samples contained tritium at an average concentration of 272 pCi/L. The 2005 control station results averaged 135 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. l.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. 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 130 pCi/L for tritium and less than 10 pCi/L for select gamma emitters.
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.
- . 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.
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.
Table IV-C.3 provides a statistical summary of the drinking water tritium and gamma spectroscopy results.
Table IV-C.3.a provides the results of the quarterly samples.
- 4. 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. Of the six indicator samples, three had measurable amounts of cesium-137 and two had measurable amounts of cobalt-60. The average cobalt-60 concentration at the indicator locations was 230 pCi/L. Cobalt-60 was not detected in 2005 samples (The average cobalt-60 concentration at the indicator locations ranged from 30 to 389 pCi/L from 1998 through 2004). The average cesium-137 concentration at the indicator locations was 55 pCi/L.
These results are similar to previous years' results. None of the samples taken at Fort Island Gulf Beach, the control location, indicated measurable amounts of cobalt or cesium.
Table IV-C.4 provides a statistical summary of the shoreline sediment gamma spectroscopy results.
Table IV-C.4.a provides the results of the semi-annual samples.
- 5. There were no unmonitored spills or releases of radioactive material in 2006 that could have the potential to contaminate the groundwater per the guidelines of the groundwater protection initiative.

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. None of the required radionuclides were found in measurable quantities. The highest cesium-137 LLD for station C29 was 28 pCi/kg. Naturally occurring potassium-40 was quantified in all eight samples at concentrations near 3000 pCi/kg.
Table IV-D. 1 provides a statistical summary of the carnivorous fish gamma spectroscopy results.
Table IV-D. l.a provides the results of the quarterly samples.
- 2. Quarterly oyster samples were taken at the same locations as fish samples, C29 and C30. Of the isotopes required to be evaluated, none indicated measurable amounts of radioactivity. However, silver- 11Oin was quantified in four samples at C29, and one sample at C30, with an average concentration of 350 pCi/kg and a range of 38 to 845 pCi/kg.
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. Four of twenty-four indicator samples had measurable amounts of cesium-137 with an average concentration of 30 pCi/kg and a range of 25 to 36 pCi/kg. This is similar to recent years results. Three of twelve control station samples had measurable amounts of cesium-137 with an average concentration of 49 pCi/kg and a range of 43 to 59 pCi/kg.
Table IV-D.3 provides a statistical summary of the broad leaf vegitation gamma spectroscopy results.
Table IV-D.3.a provides the results of the monthly samples.
- 4. Citrus samples are taken at station C19 and watermelon samples were obtained at station C04. None of the required radionuclides were found in measurable quantities in watermelon, but Cs-137 was quantified at 113 pCi/kg in the citrus sample.
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.
