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 2003 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 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 programs sampling and analysis 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-I 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 2003 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 key, shaded boxes indicate LLD values, while open boxes indicate measured values. 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.

FLORIDA DEPARTMENT OF HEALTH - INTERLABORATORY COMPARISON PROGRAM DATA The EPA crosscheck program ceased operation at the end of 1998. To meet the requirements for a crosscheck program, the Florida Department of Health participates in the Department of Energy's Environmental Measurements Laboratory (EML) Quality Assessment Program. As of March 2003, EML transferred to the Department of Homeland Security. The following units are used for each of the four media: Air Filters: Soil: Vegetation: Water: Bq/filter Bq/kg Bqlkg Bq/L Analytical performance is based on historical analytical capabilities for individual analyte/matrix pairs. Acceptable performance is designated by an WA". Acceptable with warning is designated by a 'W". Performance which is not acceptable is designated by an RN".

The "warning" indication for the soil samples was attributed to an error on the part of a Florida Dept of Health analyst in determining the volume of the sample. The Dept. of Health Environmental Manager counseled the analyst on the need to follow the data verification procedure. Corrected values of 2059 and 509 for Cs-137 and K-40 are much closer to the EML value and would likely have been reported as acceptable. 12

aI 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 312 gross beta samples and 312 iodine samples. Tables IV-A.2 and IV-A.3 provide the results for each weekly air sample. Of 312 particulate samples analyzed for gross beta activity, 310 had measurable activity. The average indicator concentration was 15 pCi/1000 m3 with a range of 4 to 32 pCiJ1000 i 3. The average indicator concentration for 1996 through 2001 was 15 pCi/1000 in3, and 17 pCi/1000 3 for 2002. The control location concentration for 2003 averaged 15 pCi/1000 m3, with a range of 4 to 29 pCi/1000 i 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 highest cesium LLD was 1.9 pCi/1000 i 3 for cesium 134. The gross beta LLD of 0.01 pCi/m3 and Iodine 131 LLD of 0.07 pCi/ 3 were not attained for air sample station C40 and C47 as complete samples were not obtained for several sampling periods as listed below. Station C47 is the control station in Orlando. C47: 7/21 to 7/29 Run time of approx. 73 of 191.8 hours due to loss of power. C47: 7/29 to 8/5 Run time of approx. 135 of 167 hours due to failed sample pump. C40: 8/11 to 8/19 Run time of approx. 37 hours of 191.8 hours due to loss of power. C40: 8/19 to 8/26 Run time of approx. 125 hours out of 169.5 hours due to power outage. 13

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 2003. The highest on-site dose was 117 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 82 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 49 mrem/yr. The average for all stations (except control) was 58 mrem/yr for 2003 and 59 mrem/yr for 2002. Direct radiation results are similar to previous years and show no change of significance. 23

I-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 (C 14G and C 14H) and at one control location (C13) near the mouth of the intake canal. Of twenty-four indicator samples, ten had measurable tritium at an average concentration of 778 pCi/L. The sample with the highest concentration of tritium, 4071 pCi/L, was obtained in April at station C14H near the head of the discharge canal. The seawater tritium activity is consistent with the concentration of tritium in the liquid waste stream. Two control station samples contained tritium at an average concentration of 91 pCi/L.

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

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.

3.

Quarterly drinking water samples are drawn from three locations: the Crystal River City Hall (C07), the Days Inn Motel (CIO), 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.

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. Of the six indicator samples, three had measurable amounts of cobalt-60 or cesium-137. The average cobalt-60 concentration at the indicator locations was 126 pCi/L for 2003, as compared to 54 pCi/L for 2002, 30 pCi/L for 2001, 98 pCi/L for 2000, 118 pCi/L for 1999, and 389 pCi/L for 1998. The average cesium-137 concentration at the indicator locations was 37 pCiIL for 2003, as compared to 53 pCi/L for 2002, 28 pCi/L for 2001, 49 pCi/L for 2000 and 65 pCiJL for 1999. None of the samples taken at Fort Island Gulf Beach, the control location, indicated measurable amounts of cobalt or cesium. These results are similar to previous years' results.

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 31 pCi/kg. Naturally occurring potassium-40 was quantified in all eight samples at concentrations near 3000 pCi/kg.
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 lOin was quantified in three samples at C29, with concentrations of 545 pCi/kg, 314 pCi/kg, and 37 pCi/kg. This is similar to 2002 and somewhat lower than 2001, during which silver-I lOrm was identified in four samples, with activity ranging from 628 pCi/kg to 3509 pCi/kg. Silver-IlOi in 2001 was associated with higher than normal releases of silver-ilOmin liquid effluents in late January. The elevated silver-ilOi in liquid effluents was in turn due to a release of radioactive material from a plant demineralizer (ref. NCR 46245).
3. Monthly broad leaf vegetation samples were taken at two indicator locations, C48A and C48B, and one control location, C47. Eight of twenty-four indicator samples had measurable amounts of cesium-137 with an average concentration of 31 pCi/kg and a range of 19 to 53 pCi/kg. This is similar to recent years results. Six of twelve control station samples had measurable amounts of cesium-137 with an average of 41 pCi/kg and a range of 6 to 137 pCi/kg.
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 20 pCi/kg in the citrus sample.
