INTRODUCTION This report is submitted as required by Technical Specification 6.9.1.5(c) to Crystal River Facility Operating License No. DPR-72.      In accordance with this specification, the following information must be included in this report:
           - Summaries
           - Interpretations Unachievable LL0s, and
              - An analysis of trends of the results of the radiological environmental studies and previous annual reports.
              - An assessment of any observed impact of plant operation on the environment.
NOTE:    If harmful effects or evidence of irreversible damage are detected by the monitoring, the Report shall provide an analysis of the problem and a planned course of action to alleviate the problem.
           - Summarized and tabulated results, in the forrac of Regulatory Guide 4.8 (December 1975), of all radiological environmental samples taken during the report period.
NOTE:    If some results are not available for inclusion, the report shall note and explain the reason for the missing results. The missing results shall be submitted as soon as possible in a supplementary report.
          - A summary description of the REMP,
          - A map of all sampling locations keyed to a table giving distances and directions from the reactor.
          - Unavailability of milk or fresh leafy vegetable samples required by Table 3.12-! of Technical Specifications.
          - The results of land use censuses.

==SUMMARY==
DUCRIP110N Of RADIOLOGl{AL ENVIRONMENTAktgfl10 RING PROGRQi The analytical results of the Crystal River Unit 3 (CR 3) operational Radiological Environmental Monitoiing Program (REMP) for 1990 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 perforrued by the State of rlorNa Department of Hedth and Rehabilitative Services (FDHRS), Office of Radiation Control. The State also perfctms the required analyses, participates in the Environmental Protection Agency's (EPA's) interlaboratory Comparison Program, and performs the annual land use census.
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 ;he analytical results are below the lower limit of detection (LLD) of the sa' rJ e. Sample LLDs are generally much lower than the required 'a priori" LLO. Unen measurable results are reported, the values are also usually less than the required "a priori" LLD.
The results of the 1990 REMP have been compared to previqus years' results.
1his comparison, in part illustrated by the trend graphs 2 of Section IV, shows no evidence of increasing radionuclide buildup in any of the sample media.
Additionally, these results verify the effectiveness of in plant measures for control}ingradioactivereleases.
results (based upon actual release                                When combined with dose calculation data and a hypothetical individual residing at the Site Boundary), the REMP data indicate that the environmental impact of CR 3's %:" tion is not significant.
I Trend graphs illustrate the mean measured concentration of a particular radionuclide for the year. When measurable results are not ostained, the highest sample LLD is plotted.
2f or 1990 reletses, the whole body dose commitment to the maximum individual was calculated to be 0.38 mrem.

N.D.K.:     Normalized deviation of the mean from the known value, as defined in EPA-600/4-01-004.
NDP:        No data provided. No data was provided to EPA for inclusion in their report.
NA:         Not available. Report containing this data has not yet been received from EPA, Las Vegas.
ACTION LEVEL:
(1)        Causes Erroneously over estimated chemical recovery of strontium carrier.
Corrective Action: Try to improve purity of isolated strontium carrier.
(2)        Cause: Incorrect counting efficiency used in calculation.
Corrective Action: Double check all parameters used in                                                                                                     I the calculation.

,                    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 77 mrem /yr at station C62 (NNE at 5300 feet). The highest off site dose was 51 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 C64 are not available si:.s e the TLD package was missing at collection time.

I IV C. WATEREQRNE PATHWAY To evaluate the waterborne pathway, seawater, groundwater, drinking water, and shoreline sediment samples are taken.
: 1. Monthly seawater grab samples are taken at two locations in the discharge canal and at one control location near the mouth of the intake canal. Of twenty-four indicator samples, nine had a measurable amount of Tritium at an average level of 301 pCi/L. Five samples taken at the control location, Cl3, indicated measurable amounts of Tritium at an average level of 127 pCi/L.
Gamma spectral analysis was performed on thirty-six samples. Isr the required radionuclides, there were no measured activities.
: 2. Semiannual groundwater samples are taken at one location, station C40.
Gamma spectral and Tritium analyses are preformed on both samples. All results were less than the LLD. Since plant startup, all results, except for the results of one 1985 Tritium analysis, have been less than LLD. As indicated by figure IV-C.2, the 1985 Tritium value of 170 pCi/L is less than the typical LLD, ar.d much less than the required "a priori" LLD of 2,000 pC1/L.
: 3. Quarterly drinking water samples are drawn from three locations: the Crystal River Public Water Plant (CC7), the Indian Waters Public Water Supply (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 for Tritium or the required gamma emitters.
: 4. Semiannual shoreline sediment samples are taken at three indicator locations in the discharge canal (Cl4H, Cl4M, Cl4G) and one control location (C09) at Fort Island Gulf Beach. Of the eight samples analyzed, four had measurable amounts of Cs-137. Cobalt 60 was identified in all six indicator samples taken in the discharge canal. (See Table IV C.4.a.)
Cobalt-58 was identified in five of the six discharge canal samples. No other gamma emitters attributable to CR 3 were found in measurable quantities.

IV D. INGESTION PATHWAY To evaluate the ingestion pathway, fish, oysters, citrus, and watermelon samples are taken.
: 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 Cs-137 LLD for station C29 is 48 pel/kg.
: 2. Quarterly oyster samples were taken at the same locations as fish samples, C29 and C30. Two of four C29 samples had measurable amounts of Co-58 at an average level of 47 pCi/kg. The Third Quarter sample at C29 indicated Co 60 at a level of 76 pCi/kg. Radionuclides attributable to CR 3 were not identified in the four samples taken at C30, the control station.
: 3. Monthly broadleaf vegetation samples were taken at two indicator locations, C48a and C48b, and one control location, C47. Twenty of twenty-four indicator samples had measurable amounts of Cs-137 with an average concentration of 90 pC1/kg and a range of 17 to 288 pCi/kg.
Twelve of twelve control station samples had measurable amounts of Cs-137 with an average of 167 pCi/kg and a range of 32 to 970 pCl/kg.
: 4. Annual watermelon and citrus (oranges) samples are taken at stations C04 and C19, respectivwly. Cesium 137 was measured in the watermelon sample at a level of 7 pCi/kg.
