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 2008 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 1-1 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 2008 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 aparticular 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. AIRBORNF 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. I provides a statistical summary of the analytical results for 310 gross beta samples and 310 iodine samples.

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

Three hundred ten particulate samples were analyzed for gross beta activity, all of which had measurable activity except 8 samples. The average indicator concentration was 14 pCi/1000 m3 with a range of 3 to 29 pCi/1000 M 3. The average indicator concentration since 1996 was in the range of 14 to 19 pCi/1000 M 3. The control location concentration for 2008 averaged 14 pCi/1000 M 3, with a range of 3 to 24 pCi/1000 M3.

Three hundred ten samples were analyzed for iodine activity, with none having measurable activity. The highest iodine LLD was 0.05 pCi/m3. This LLD value was influenced by a partial sample run due to a power outage at the sample station.

Quarterly composite data are summarized in Table IV-A.4. Measurable quantities of cesium were not identified in any particulate filter sample. The highest cesium LLD was 2.1 pCi/1000 m3 for cesium 134.

There were two non-collected samples for the year 2008 located at air sample station C46 due to the sampler was non-operational for two weeks and a partial week due to a loss of power to the station because of a circuit breaker panel failure. This breaker panel had to be totally rebuilt and had failed due to its age. There was one instance of air sample station C07 being down for 29.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months due to a power outage.

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 2008.

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

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

The highest on-site dose was 115 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 72 mrem/yr at station C65 (ESE at 1740 feet).

The highest off-site dose was 63 mrem/yr at station C40 (east at 3.5 miles). The control station (C47) dose was 60 mrem/yr.

The average for all stations (except control) was 59 mrem/yr for 2008, 54 mrem/yr for 2007, and 53 mrem/yr for 2006. Direct radiation results are very slightly elevated, but 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 (C13) near the mouth of the intake canal. Of twenty-four indicator samples, six had measurable tritium at an average concentration of 103 pCi/L, as compared to thirteen measurable samples containing tritium with an average of 282 pCi/L in 2007. The sample with the highest concentration of tritium, 150 pCi/L, was obtained in October 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 91 pCi/L. The 2007 control station results averaged 194 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. I provides a statistical summary of the seawater tritium and gamma spectroscopy results.

Table IV-C..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 150 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.

3.

Quarterly site ground water samples are taken at nine locations surrounding the perimeter of the CR-3 protected area.

Presently 5 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 many years ago. This discharge line has recently been leak tested and is leak free. There are no other know leaking plant components. The five wells that have shown measurable amounts of tritium range from 80 to 1110 pCi/L. These wells have been sampled additionally on a monthly basis to develop trend data. This 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). These two wells are showing measurable amounts of tritium in the range of 111 to 395 pCi/L, which are a result of plant discharges from the SDT-I. These discharges are being minimized through operational focus. The tritium values are below the reporting criteria of the ODCM or the NEI 07-07 Ground Water Protection Initiative Guidelines. There have been no measurable amounts of gamma emitting radionuclides in any of these wells. 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 hydro-geologist as part of the NEI Ground Water Protection Initiative. Additionally, the ground water at the CR-3 site is too saline for use as a potable water source.

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

Table IV-C.2.b.1 provides the results of the quarterly samples.

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

4.

Monthly non-REMP required well samples were collected as discussed above. Two wells were sampled. These two wells are located on either side of the site percolation ponds. The information is discussed above. Both of these wells showed no measurable amounts of any radionuclide of interest. The tritium concentration in these wells have decreased significantly due to a focused reduction in the number of discharges from the station drain tank (SDT-1) to the site percolation ponds.

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

Table IV-C.2.c. 1 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 (C 10), and the Yankeetown City Well (C 18). 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.

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. Of the six indicator samples, two had measurable amounts of cesium-137 and there were no measurable amounts of cobalt-60. The average cobalt-60 concentration in 2007 was 41 pCi/L. The average cobalt-60 concentration at the indicator locations ranged from 30 to 389 pCi/L from 1998 through 2007. In 2008 the average cesium-137 concentration at the indicator locations was 25 pCi/L. The average cesium-137 concentration in 2007 was 23 pCi/L. These 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.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.

7.

There were no unmonitored spills or releases of radioactive material in 2008 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. None of the required radionuclides were found in measurable quantities. The highest cesium-137 LLD for station C29 was 33 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. Silver-1 I10m was not quantified in any oyster samples collected in 2008. In 2007, silver-1 10m was quantified in three samples at C29 near the end of the discharge canal, with an average concentration of 85 pCi/kg and a range of 58 to 118 pCi/kg. In 2006, silver-10 lOn 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. Three of twenty-four indicator samples had measurable amounts of cesium-137 with an average concentration of 92 pCi/kg and a range of 12 to 246 pCi/kg. This is comparable to the levels found in 2007, but is higher than the previous four years. One sample had a measured concentration of 246 pCi/kg, which has caused the average value to increase. It is believed this 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. Seven of eight samples collected following the spike sample contained no measurable Cs-I37 with the exception of one sample that had a measured Cs-137 concentration of 12 pCi/kg. Seven of twelve control station samples had measurable amounts of cesium-137 with an average concentration of 47 pCi/kg and a range of 22 to 107 pCi/kg.

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.

Citrus samples are taken at station C19. In 2008 there were no watermelon samples available at station C04. Due to crop rotation there were no locally grown watermelons in the area nearby the facility. None of the required radionuclides were found in measurable quantities in the citrus samples.

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.
