SUMMARY

Df3sRIPT10N OF RADIOLOOLLAL. ENVIRONMENTAL MONITORING PROGRAM The analytical results of the Crystal River Unit 3 (CR-3) operational Radiological Environmental Monitoring Program (REMP) for 1991 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 and Rehabilitative Services (FDHRS), Office 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. Samole 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 I-2. Figure I-l 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" LLO. The. esults of the 1991 REMP have been compared to previpus years' results. This comparison, in part illustrated by the trend graphs 2 of Section IV, shows no evidence of increasing radionuclide builduo in any of the sample media. Additionally, these results verify the effectiveness of-in-plant measures for When combined with dose calculation control {ingradioactivereleases. results (based upon actual release data and a nypothatical individual residing at the Site Boundary), the REMP data indicate that the environmental impact of CR-3's operation is not significant. E 6 I rend graphs-illustrate the mean measured concentration of a particular Tradionuclide for the year. When measurable results are not obtained, the highest sample LLD is plotted. 2 or 1991 raleases, the whole body dose commitment to the maximum individual F was calculated to be 0.13 mrem.

LAND USE CENSUS A land-use census to identify the nearest residences, vegetable gardens, and potential milk-producing animals within a five mile radius of the nuclear plant was conducted in June. The distance in miles and bearing in degrees for each receptor type in each of the sixteen sectors is summarized below.

• None
  • All sectors around the plant which are not exclusively water or

. marshland might occasionally have milk-producing animals at the plant bounda ry. Most of the land adjacent to the plant site is woodland; however, much of-the land in the immediate area is pastureland for cattle and a few horses. Stray cattle are often seen in the wooded areas ad.iacent to the plant site. These cattle are raised for beef or veal-At times there may be fresh females in these herds, but these -animals roam freely and are not milked. A few goats have also been located at residences within the survey area. None of these cows or goats are known to be providing milk for human use, and the owners are not willing to make samples of milk available. 11

RECT RA0!AT10tj Direct radiation measurements (using TLDs) were taken at sixteen locations within one mile of the plant, at thirteen locations ranging from 2.8 to 6.3 miles from the plant, and at one control location 80 miles from the site. The highest on-site dose was 97 mrem /yr at station C62 (NNE at 5300 feet). The highest off-site dose was 53 mrem /yr at station C75 (East at 4.2 miles). The control station (C47) dose was 47 mrem /yr. The average for all stations was 53 mrem /yr. Third quarter results for station C09 and fourth quarter results for station C78 are not available as the TLD packages were missing at collection time. First quarter results for station C61 were rejected due to mechanical failure and possible procedural error during TLD preparation. 3 e n .E i L l-l 24 I

_,.. _ _. ~..... _ > 4 IV-C. RQ@S!(LfMWM To ovaluate the waterberne pathway, seawatwr, groundwater, drinking water, and shoreline sedircent camples are taken. 1. Monthly seawater gegb semples are taken at two locations in the discharge canal and at ons control locatico near the muuth of the intake canal. Of twenty four indientnr samples, nine had a meascrable amount of Tritium at 'i an average level of 597 pC1/L. Seven camples taken at the control location, C13, indicated measurable amounts of Tr$ttum at an average level of 172 pCi/L. Gamma spectral analysis was performed on thirty-3.ix samples. For the reqvired radionuclides, there were no measured activitici. I 2. Semiannual groundwater samplas are taken at one location, station C40. l Gamma spectral and Tritium analyses are proformed on both samples. All results were less than the LLD, $ lace plant startup, all rascits, except for the results of one 1985 Tritium analysis, have been less thno LLD. As indicated by figure IV-C.2, the 1995 Tritium value of 170 pC1/L is less I i than the typical LLD, and much less than the required "a priori" LLO of 2,000 pCi/L. 3. Quarterly drinking water samples are drawn from three locations: the Crystal River-Public Water Plant (007), the indtan Water; Pubile Water Supply (C10), and the Yankeetonn City Vall (018). All samples were collected and analyzed for gamma emitters and Tritium. None of the samples yielded measurable activities for Tritium or the required gamma emitters. 4. Semiannual shoreline sediment s:mples Aru taken at three indicator locations in the discharge canal (Cl4H, C14ti, Cl4G) and one control location (C09) at fort Island Gulf Beach. Of theleight samples analyzed, four had measurable amounts of Cs-137. Cobalt 60 was identified in all six indicator samples t: ken in the discharge canal. (SeeTableIV-C.4.a.) Cobalt-58 was identified in two of the six discharge canal samples. No other gamma emitters attributable to CR-3 were found in measurable quantities. l r l N I l l H l $6 1 l ~

E 1 - ~. IV-D. INGESTION PATHWAY To evaluate the ingestion pathway, fish, oystors, citrus, and watermelon samples are taken. 1, Quarterly carnivorous fish samples were taken at two locations: C29 ri the end of the discharge canal, and C30, the control loca. ion near th mouth of the intake canal. None of the required radionuclides were frem, in measurable quantities. The highest Cs-137 LLD for station C29 is 18 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 for, none were found in measurable quantities, although Ag-110m was identified at a level of 540 pCi/Kg in the first quarter sample. 3. Monthly broadleaf vegetation sample: were taken at two indicator locations, C48a and C48b, and one control location, C47. Sixteen of twenty-f9Jr indicator samples had measurable amounts of Cs-137 with an average concentration of 52 pCi/kg and a range of 19 to 109 pCi/kg. All control station samples had measurable amounts of Cs-137 with an average of 147 pCi/kg and a range of 29 to 109 pCi/kg. 4 Annual watermelon and citrus (oranges) samples are taken at stations C04 and C19, respectively. Cesium-137 was measured in the citrus sample at a level of 7 pCi/k. 9 42
