R!aatARY nrtretpT1hW nF THF Rantnf nctral FMVfDnWMFWTAl HnWitnRIE PRnCP&M The analytical results of the Crystat River Unit 3 (C-3) operational Radiological Environmental Monitoring Program (REMP) for 1998 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.
Sangling 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 Environmental Protection Agency's (EPA's) Interlaboratory Comparison Program, and performs the annual land-use census. Prior to 1990, l
the program was split between the Department of Health and the University of Florida. The transition to the State performing all of the programs sanpling and analysis in 1990 is evident in several of the trend praphs, 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. Sanple frequency and analysis type may be determined from Table 12. Figure I-1 Ittustrates the relevant exposure pathways.
Figures 12, 3, and -4 include stations C07, C13, C27, and C74 which were omitted in the 1997 report due to errors in report preparation. The statistical summary page for broad leaf vegetation, Table IV-D.3, of the 1997 report was also in error. This table was corrected and resubmitted in this report (page 53).
1 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.
I The results of the 1998 REMP have been conpared to previous years' results. This comparison, in part j
filustrated by the trend graphs of Section IV, shows no evidence of consistent long-term increasing trends i
in any of the sanple 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, i
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 i
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 sanples obtained is reported. For exenple, 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.

The r etrol location is 80 miles ESE of the plant, at the State Bureau of Radiation Control in Orlando. Table IV-A.1 provides a statistical suutary of the analytical results for 308 gross beta sanples and 308 iodine samples. Tables IV A.2 and IV A.3 provide the results for each weekly air sample. Of 308 particulate samples analyzed for gross beta activity, 304 had measurable activity. The average indicator concentration was 15 pCf/1,000 m' with a ran The average indicator l concentration for 1996 and 1997 is also 15 pCf/1000 m'ge of 4 to 33 pCi/1,000 m'. The control location concentration for 1998 averaged 15 pCf/1,000 m'. 1 Three hundred and eight samples were analyzed for lodine activity, with none having measurable activity. Quarterly composite data are summarized in Table IV-A.4. Measurable quantitles of cesium were not identified. The highest ceslun LLD was 1.2 pcl/1,000 m' for cesium 134. The gross beta LLD of 0.01 pC1/m' and Iodine 131 LLD of 0.07 pCi/m' were not attained for the following air samples: Station C40 from 8-24 through 9-15: Extended power outage due to storm damage.

r fv.a. ntarci manfaffnu Direct radiation measurements (using TLDs) were taken at seventeen (statione C60 through c73 and station C27) locations 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. The highest on site dose was 109 mres/yr at station C71 (WWW at 3600 feet). The increase at CT1 of approximately 30 mrem /yr since 1992 is attributed to the TLD being moved due to cooling tower construction. The new location is 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 highest off-site dose was 56 mrem /yr at station c40 (east at 3.5 miles). The control station (c47) dose was 45 mrem /yr. The average for att stations was 51 ares /yr for 1998 and 52 mrem /yr for 1997. Direct radiation results are similar to previous years and show no change of significence. 22

f IV-f_ uATFean9MF PATNuaY To evaluate the waterborne pathway, seawater, ground water, drinking water, and shoreline sediment samples are taken. 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, one had measurable tritium at a concentration of 151 pCf/L. One control station sample obtained on July 2nd contained tritium at a concentration of 314 pCf/L. Liquid releases containing tritium occurred on July 1st. Gamma spectral analysis was performed on thirty-six samples, none of which showed measurable amounts of the gamma emitters of interest. 2. Semlannual ground water samples are taken at one location, station C40. Gamma spectrat 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 pct /L. Analysis of ground water in the vicinity of CR-3 is done at a sensitiv!ty of approximately 169 pcl/L for tritium and 10 pCf/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 (C10), and the Yankeetown City Wall (C18). All samples were collected and anatyred for gamma emitters and tritium. None of the samples yielded measurable activities of tritium or the required gamma emitters. The detection limits 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, all had measurable amounts of cobalt 60 and four had measurable amounts of cesium-137. The average cobatt 60 concentration at the indicator locations was 384 pC1/L for 1998 as compared to 371 pCI/L for 1997 and 595 pCf /L for 1996. The average cesf um-137 1 concentration at the indicator locations was 50 pCf/L for 1998 as compared to 64 pcl/L for I 1997 and 66 pCf/L for 1996. None of the samples taken at Fort Island Gulf Beach indicated ) measurable amounts of cobalt or cesium. Naturally occurring radium-226 was quantified at levels ranging from 554 to 1619 pCf/L. These results are similar to previous years' results. j i 26

tv n-tuartfinu paTuuay i To 6*aluate the ingestion pathway, fish, oysters, broad leaf vegetation, citrus, and watermelon saept&,'are taken. 1. Otr.rterly carnivorous fish samples were taken at two locations: C29 at the end of the d scharge canal, and C30, the control location near the mouth of the intake canal. None of
- he required radionuctides were found in measurable quantitles. The highest cesium 137 LLD for station C29 was 25 pcl/kg. Naturally occurring potassium-40 was quantified at levels ranging f rom 1863 pCf /L to 2643 pC1/L in the eight 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-110m was quantified in each of the four indicator samples, with activity ranging from 427 pC1/L to 5785 pCf/L. ~ 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. 26 pCf /kg and a range of 9 to 63 pC1/kg. Ten of the twelve control station samples had measurable amounts of cesium 137 with an average of 44 pCl/kg and a range of 22 to 70 pcl/kg. .4. Citrus samples are taken at station C19. None of the required radioisotopes were quantified. Watermelon samples, normally obtained at station C04 were unavailable. Repeated efforts were made to locate watermelon within the general vicinity of C04, but none were located. Alternate sample media will be identified for the 1999 growing season. l i I 40
