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 2007 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 1-1 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 2007 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" columnm 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.

This study, along 'with other factors has prevented shipment of this series of unknown samples. As of this typing, the set has still not been received by the DOH lab in Orlando. There are no criteria for the number of unknown samples to be tested. All sample media has been tested, which meets the intent of the program. This event is documented in the plant corrective action program (CAP) under Nuclear Condition Report (NCR) 275233.

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 317 gross beta samples and 311 iodine samples.

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

Three hundred seventeen particulate samples were analyzed for gross beta activity, all of which had measurable activity except 2 samples. The average indicator concentration was 17 pCi/1000 m 3 with a range of 4 to 37 pCi/1000 mi. The average indicator concentration since 1996 was in the range of 15 to 19 pCi/1000 m3 . The control location concentration 3

for 2007 averaged 19 pCi/1000 m , with a range of 4 to 34 pCi/1000 m3.

Three hundred eleven 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, except in one sample at station C07 where cesium 137 was measured at 1.2 pCi/1000m 3 . The highest cesium LLD was 1.7 pCi/1000 mi3 for cesium 134.

There was one non-collected sample for the year 2007 located at air sample station C07 due to the sampler was non-operational for one week and a partial week due to a loss of power to the station because of a circuit breaker panel failure.

There was one instance of air sample station C46 being down for 45.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> due to a power failure. There were 6 instances of air sample station C40 being down for partial weeks due to problems associated with GFI circuits and damage to the power line from a fallen tree limb. The control air sample station C47 was down for several hours due to a power outage for scheduled electrical work. The remaining sample stations were in service 100% of the time, with exception of filter changes and air pump/gas meter replacements. The percentage of down times for the 4 stations are as follows:

C07 2.39%

C40 5.08%

C46 0.52%

C47 0.18%

The air sample station's down times are documented in the plant CAP under NCRs 236557, 237736, and 239122.

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-one TLDS were collected during 2007.

Table IV-B provides a statistical summary of the analytical results for 131 TLDs sampled throughout the year.

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

The highest on-site dose was 107 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 66 mrem/yr at station C65 (ESE at 1740 feet).

The highest off-site dose was 61 mrem/yr at station C40 (east at 3.5 miles). The control station (C47) dose was 50 mrem/yr. The average for all stations (except control) was 54 mrem/yr for 2007, 53 mrem/yr for 2006, and 54 mrem/yr for 2005. Direct radiation results are similar to previous years and show no change of significance.

There was one instance of a lost TLD at station C77 when the power pole it was mounted to was replaced with a concrete pole during the fourth quarter of 2007. This event is documented in the plant CAP under NCR 254925.

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 (C 13) near the mouth of the intake canal. Of twenty-four indicator samples, thirteen had measurable tritium at an average concentration of 282 pCi/L as compared to two measurable samples containing tritium with an average of 445 pCi/L in 2006. The sample with the highest concentration of tritium, 914 pCi/L, was obtained in April 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. Four control station samples contained tritium at an average concentration of 194 pCi/L. The 2006 control station results averaged 272 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. 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 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 69 to 808 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 244 to 1199 pCi/L, which are a result of plant discharges from the SDT-1. 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. This information is documented in NCR 228274. 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.l 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. Four wells were sampled. Two of these wells are located on either side of the site percolation ponds. The information is discussed above. Two other wells located north of the Units 1, 2, & 3 discharge canal and south of the Units 1, 2, & 3 intake canal were also sampled for tritium and gamma emitters. Both of these wells showed no measurable amounts of any radionuclide of interest.

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 (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.

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, 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 41 pCi/L. The average cobalt-60 concentration in 2006 was 230pCi/L. The average cobalt-60 concentration at the indicator locations ranged from 30 to 389 pCi/L from 1998 through 2006. The average cesium-137 concentration at the indicator locations was 23 pCi/L. The average cesium-137 concentration in 2006 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 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 2007 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 communiqu6s 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 25 pCi/kg. Naturally occurring potassium-40 was quantified in all eight samples at concentrations near 3000 pCi/kg. Fish samples are required to be collected every 92 days and have a sample frequency tolerance of 1.25 times the interval specified. There was one instance in the first quarter where the sample was collected 15 days greater than this tolerance, although the sample was actually performed within the calendar quarter. The Department of Health personnel responsible for collecting the sample tried on numerous occasions to collect the fish, but were unsuccessful in meeting the time frame. This event is documented in the CAP under NCR 234028.

Table IV-D. I 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-i 1Oim 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-1 IOm 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. Five of twenty-four indicator samples had measurable amounts of cesium-137 with an average concentration of 89 pCi/kg and a range of 29 to 271 pCi/kg. This is elevated as compared to the previous four years.

One sample had a measured concentration of 271 pCi/kg, which has caused the average value to increase by a factor of

3. 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. The following samples collected after this sample had no measurable cesium-137. Six of twelve control station samples had measurable amounts of cesium-137 with an average concentration of 44 pCi/kg and a range of 33 to 64 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 the citrus or watermelon 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.
