I. INTRDDUCTION The Radiological Envi ronmental Monitoring Program provides information which can be used to assist in assessing the type and quantity of radiation exposure in unrestricted areas resulting from plant operation. The Program is conducted via a contract with the University of Florida, Department of Environmental Engineering Sciences, Gainesville, Florida and a grant to the State of Florida, Department of Heal th and Rehabilitative Services, Orlando, Florida. The parts of the Program for which each are responsible are listed in Table I-1. In essence, the Program provdes a continuation of the preoperation program so that any increases of radioactivity in the en-vironment can be detected. No pathway has shown any confirmed increases of radioactivity in the environment due to plant operation during this report period. The most significant achievement in 1979 was that the analyses for all nuclides in all pathways had annual average Lower Limits of Detection (LLDs) that were equal to or less than that required. In the summary analysis tables, two terms are used which need explanation. The term "ND" means that the activity of the nuclide for the samples was non-detectable or less than half of the LLDs for those samples. The term "<LLD" means that the activity of the nuclide for the samples was less than the LLDs for those samples. In this way, an apparent change in activity below the lower limits of detection can be trended without getting bogged down in " actual" activity values. The statistical evaluation of operational analyses were performed using one-fourth the LLD value if the activity was non-detectable and using three-fourths the LLD value if the activity was less than the LLD value. When a non-detectable or less than LLD concentration used in an evalu 4tico, the results are prefaced with a "<" sign to show that the results do not indicate only detected activity. Finally, the statistical evaluation of the operational concentrations where there are preoperational results includes the median values. This is done solely for comparison to preoperational results.

11. MILK AND GREEN LEAFY VEGETABLE CENSUS Environmental. Technical Specification 3.2.1 requires a - census of animals producing milk for human consumption to be conducted semiannually. If this census - fails to locate any such animals, a census of gardens producing fresh leafy vegetables for human consumption is required annually.

The garden census, required as the result of a lack of findings on the J anuary 16, 1979, milk animal census, was completed on June 14, 1979. The critical garden (Sample Station C48) was found to be in the east sector at 4.0 miles from the plant. One Licensee Event Report (LER) was submitted to the Commission. ' LER 79-058/04L-0 was the result of not conducting a garden census within the surveillance interval required by Environmental Technical Specifica-ti on 3.2.1.2. However, the -late census did not alter the effectiveness of the sampling program because the results of the census were taken into account during the next required garden sample. A semiannual milk cow survey was completed on June 27, 1979 again with no milk animals found. The critical station for green leafy vegetables was continued at the garden 4.0 miles from the plant in the east sector. A seminannual milk cow census was completed by December 31, 1979. No milk animals were located within five miles of the plant site in this survey. The transmittal letter with report was submitted January 8,1980. mU 4

111. EDIA OTHER THAN EXTERNAL RADIATION Environmental Technical Specification 3.2.2 requires that samples be taken and analyzed per ETS Table 3.2-2 and that analysis LLDs will be equal to or less than those in ETS Table 3.2-5A and B. Each analysis routine of each pathway in ETS Table 3.2-2 will be summarized, interpreted, and evaluated in the order presented. 5

AIR INHALATION PATHWAY {} The Air Inhalation Pathway is one of two pathways split between the Univer-sity and the State. In addition to the assigned stations, the University operates a station at C47. Weekly Gross Beta Analysis The summary for the gross beta analysis is in Table 111-1. Six weekly sam-pies were not collected and analyzed: C04 for the week of 01-28-79 due to equipment failure. C41 for the week of 08-03-79 due to power failure. C41 for the week of 11-02-79 because air filter was not sent with j charcoal cartridge. C46 for the week of 11-05-79 because of operator error. C47 for the week of 09-21-79 because of annual meter calibration. C47 for the week of 10-05-79 due to equipment failure. All other samples were collected and analyzed. There are no critical stations for this type of analysis. A statistical evaluation of the operational data and a comparison witn the preoperational data is presented in Table III-5. The operational concentrations are similar to the preoperational concentra-(~)T tions and are lower than the 1978 operational concentrations. Weekly 1-131 Analysis The summary for the iodine analysis is in Table III-2. Six weekly samples were not collected and analyzed: C41 for the week of 06-15-79 because the charcoal cartridge fell apart while being removed from the particulate filter. C41 for the week of 08-03-79 due to power failure. C41 for the week of 10-05-79 because the pump was reported to be unplugged. C46 for the week of 11-05-79 due to operator error. C47 for the week of 09-21-79 due to annual meter calibration. C47 for the week of 10-05-79 due to equipment failure. High LLDs for the third quarter, Station C41, can be attributed to long time elapsed until counting due to equipment failure. High LLDs were noted on 02-09-79and 02-23-79 at Station C47 due to low volume of air collected with faulty pump. All other samples were collected and analyzed. Station C41 is the critical station for this type of analysis and no samples had activity greater than 10 times the control stations' values. A statistical evaluation of the operational data is presented in Table 111-5. There are no preoperational

()

data. l 6

a q The statistical analysis of the critical and control stations for the O period of this report is as follows: 3 Critical Station Mean Value = <.012 pCi/m 3 Critical Station 95 Percentile Value = <.040 pCi/m Control Stations Mean Value = <.011 pCi/m3 3 Control Stations 95 Percentile Value = <.030 pCi/M As with the gross beta concentrations, the Iodine-131 concentrations in 1979 were lower than the 1978 concentrations. The critical station and control station concentrations are less than their respective 1978 concentrations. Even though all samples at the critical station resulted in non detectable activity, the 95 percentile concentration appears high because of LLO differences in the two contractors collecting the data, i ) a 7

{} Quarterly Gamma Analysis The summary for gamma analysis of quarterly composites is in Table III-3. All samples were collected and analyzed. High LLDs noted for the fourth quarter at Station C41 were due to decreased sample volumes resulting from loss of the Air Particulate Filter and failure of persen changing sample to calibrate flow to one cubic foot per minute. All other samples were col-lected and analyzed and had LLDs equal to or less than those required. There are no critical stations for this type of analysis. One Licensee-Event Report (LER) was issued to. the Commission. LER 80-014/04L-0 was the result of the air concentration for Thorium-232 exceeding ten times the preoperational level at Sampling Station C41. The apparent cause of the occurrence was a coal slag pile, located six (6) meters south of the air sampler at Station C41. The increased air concentration is attributed to the high Th-232 concentra-tion in the coal slag pile. O. ..m t TO 8

i } Quarterly Sr-89 and 90 Analysis The summary of the quarterly analysis for Strontium-89 and 90 is presented in Table III-4. All samples were ' collected and analyzed. There are no j critical monitoring stations in this pathway for this type of analysis. Table III-5 presents a statistical analysis of the data. There are no pre-operational data. i The 1979 Sr-89/90 concentrations in this pathway are similar to previous . operational years' concentrations. h i 'l: ' r i t 9 i a 4

9 Q SEA WATER PATHWAY The University has the responsibility to collect and analyze sea water sam-ples. There are no additional stations for this pathway. Monthly Gamma Analysis The summary for the gamma analysis of monthly samples is in Table III-9. All samples were collected and analyzed. Sample Station C14G is the critical station in this pathway and no sample had activity greater than 10 times the control station value. A statistical evaluation of the opera-tional data and a comparison with the preoperational data is presented in Table 111-10. The concentrations of nut.lides by gamma analysis during 1979 was less than the concentrations during 1978 and the preoperational concentrations. The critical stations and the control stations concentration were almost iden-tical and both were less than the respective concentrations during 1978. One Licensee Event Report (LER) was issued to the Commission. LER 79-016/04-L was the result of Zn-65 analysis having an LLD greater than the required LLD for January at Station C09. Inadequate sample time was the apparent cause of the greater than required LLD. Quarterly Sr-89 and 90 Analysis O Tne s"mmers of the 9oerter11 eae'usis for sr-89 ead 90 is preseatee 4" Table III-10. All samples were collected and analyzed. Strontium 89/90 are not critical nuclides in this pathway. A statistical evaluation of 1979 operational data is presented in Table 111-10. 'te concentrations of these nuclides are lower than both 1977 and 1978 c N rational concentrations. 19

(. Quarterly Tritium Analysis The summary for the tritium analysis of quarterly composites is in Table 111-11. All quarterly composites were collected and analyzed. There are no critical stations for this type of analysis. A comparison of the preoperational and operational analyses is in Table 111-10. The operational concentrations in 1979 were less than those in 1978 except for K-40, and less than preoperational concentrations except for I-131 and K-40. Some preoperational activitiu that were reported were 1 less than the minimal detectable activities and this skewed the statistics i downward. 1 i 4 O. 4 1 4 i 20 i 1

(~ POTABLE WATER PATHWAY v The University has the responsibility to collect and analyze potable water samples. There are no additional stations for this pathway. Quarterly Gama Analysis The summary for the gamma analysis of quarterly samples is in Table 111-19. All samples were collected and analyzed. There are no critical stations in this pathway. A statistical evaluation of the operational data and a com-parison with the preoperational dato is presented in Table III-20. The 1979 operational activity was less than both the 1978 operational concen-trations and the preoperational activity levels. Quarterly Tritium Analysis The sumary for the trition analysis of the quarterly samples is in Table III-21. All samples were collected and analyzed. There are no critical stations in this pathway and all samples had activity that was less than the sample LLD. All preoperational sanples had an averege activity of less than 320 pCi/kg. There was, therefore, no evidence of increase in activity over the preoperational levels, or the 1978 operation-al levels. o a. j' = 33

SHORELINE EXTERNAL SEDIMENT PATHWAY {' ^ The University has the responsibility to collect and analyze shoreline ex-ternal sediment samples. There are no additional stations for this path-way. Semiannual Gamma Analysis The summary for the gamma analysis of the semiannual samples is in Table III-22. All samples were collected and analyzed. The critical stations for this analysis are Sample Stations C14H, C14M, and C14G and no sample had activity greater than 10 times the control station value. A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table 111-23. The 1979 operational nuclide concentrations are lower than the preopera-tional concentrations and the 1978 operational concentrations for almost every nuclide. The lack of more operational data prevents a more thorough comparison. Also, the control station data are similar to the critical station data. Semiannual Sr-90 Analysis The summa ry for the semiannual analyses for Sr-90 is presented in Table III-24. All samples were collected and analyzed. Sr-90 is not a critical nuclide in this pathway. A statistical evaluation of 1979 opera-tional data is presented in Table 111-23. There are no preoperational data. Sr-Od concentrations were consistent with previous operational years' concentrations. g ( ) m 37

INGESTION CRAB PATHWAY The University has the responsibility to collect and analyze crabs. There are no additional stations for this pathway. Semiannual Gamma Analysis The summary for the gamma analysis of the edible portion of semiannual samples is in Table 111-28. All samples were collected and analyzed. Sample Station C29 is the critical station in this pathway and no sample had activity greater than 10 times the control station value. A statisti-cal evaluation of the operational data and a comparison with the preopera-tional data is presented in Table 111-29. Except for naturally occurring Ra-226 and K-40, the 1979 operational con-centrations are consistent with the 1978 operational and lower than the preoperational concentrations. The concentrations of the critical and control stations during 1978 were in close agreement. One Licensee Event Report (LER) was issued to the Commission. LER 79-016/04-L was the result of Zn-65 analyses having LLDs greater than the required LLDs for the first half at Stations C29 and C30. Inadequate sample time was the apparent cause of the greater than required LLDs. 'I I O 45

The sample for the second half at C29 was collec-ted and counted but values were not reported because the sample was only 202 grams. Since the first half data at C30 had slightly high LLDs due to the small size of the sample collected, the data was not reported. All other samples were collected and analyzed. Sample Station C29 is the critical station in this pathway and no sample had activity greater than 10 times the control station value.

Monthly Gamma Analysis The summary for the gamma analysis of the monthly samples is in. Table 111-38. The samples at Sample Station C49 were not collected due to the unavailability of milk. All other samples were collected and analyzed. Sample Station C49 is the critical station for this type of analysis. A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table 111-39. The 1979 operational concentrations are less than both the 1978 operational and the preoperational concentrations. Monthly Sr-89 and 90 Analysis The summary for the monthly analyses for Sr-89 and 90 is in Table 111-40. The samples at Station C49 were not collected due to the absence of milk animals in the area. All other samples were collected and analyzed. Stront,ium 89/90 are not critical nuclides in this pathway. A. statistical evaluation of the operational data, and comparison with preoperational data (Sr-90 only) is presented in Table 111-39. O Strontium 89 showed some increase over the 1978 concentration, while Sr-90 remained consistent with 1978 concentrations and lower than preoperational concentrations. NOTE: These milk samples were collected at Control Station C47, which is in Gainesville, 52 miles away from the plant, and beyond the plant's zone of influence. O. 60

48 IV. EXTERNAL RADIATION The External Radiation portion of the Radiological Environmental Monitoring Program (Specification 3.2.3) is split between the University and the State (See Table I-1). The University also has a TLD at Sample Station C47 and the State has additional TLDs at Sample Stations C04, C40, and C46. The summaries for the University's data is in Table IV-1 and for the State's data in Table IV-2. Fourth quarter TLDs for Station C04 were lost during transit from Crystal River to the University. Because of vandalism, the fourth quarter TLDs at Station C47 were lost. No -other TLDs were lost dur-ing the report period. Sample Stations C14H, C14M, and C14G are the criti-cal stations in this pathway. Table IV-3 presents a statistical summary of all data. The 1979 data from all TLD stations compares very well with the 1978 data and the preopera-tional data. Additionally, the critical stations and the control stations of the University also compare very well. However, because the University and the State use different types of TLDs, it is necessary to report their results separately. O' a O 89
