Page 1 of 7 ~ [ a, - MCGUIRE NUCLEAR STATION ANNUAL RADIOLOGICAL' ENVIRONMENTAL MONITORING PROGRAM ~ OPERATING REPORT FOR 1983 t-t LTabl'e lisummarizes the results of the Environmental Radiological Monitoring Program for 1983. Table 2 provides a summary of-the sampling locations and Table 3 summarizes'the_ program analyses. Table 4_provides a map of sampling locations within a 13-mile radius of the station and-Table 5 provides a map of Lsampling locations within a 0.6-mile. radius of the station. Table 6 provides the location of the' nearest milk animal, the nearest residence and the nearest 1 ~ . garden of greater than 50'm2 i producing _ broad leaf vegetation in each of the 16 meteorological. sectors within a-5-mile radius of the station as determined -by the annual. land use census. I Duke Power Company's Environmental Radiological Laboratory performs the program analyses with the exception of H-3 analyses which are performed by 1 Teledyne-Isotopes..Both'the Environmental Radiological. Laboratory and Teledyne Isotopes participate in the EPA Cross-Check Program; the cross-check code designations:are CP and CJ, respectively. Table 7 provides the results of the { , Environmental Radiological Laboratory's participation in the program. Some~ unavoidable deviations from the routine sampling schedule occurred during the year. These deviations are tabulated below. 1 L Unavailable Analyses' i Sample Reason A. mr Filter / Cartridge - 1. (125), 5/17-5/24/83 Power to sampler cut off; insufficient sampler run time. '2.

McGuire Nuclear Station's. composite samplers operate such that, the rate at which the sample'is collected is uniform whereas table' notation (7) of Table-3.12-1 of the station's Technical Specifications requires' composite samplers. 4 'to ' operate such that the rate'at which the ~ sample is collected is ' proportional _ to the flow of liguid at the collection location. These i . sampling techniques are'approximately. equivalent as the-flow;of liquid in the areas being sampled (station discharge canal and inlets to water purification. l . facilities) is' fairly constant. The primary purpose of the water samples is-to quantify.the concentration of radioactive effluents'in the aqueous environment-(the exact curie content is known at the time of release).and for this'purpo.se, a time average sampling method is more representative than~a flow proportional method and is also considerably less complicated.

Page 4 of 7 j-One sample of a gamefish and one sample of a bottom feeder were collected in the vicinity'of the station discharge area and at a control location in April -and October-of 1983. These samples were specified in Table 3.12-1 of the McGuire Technical Specifications until March 29, 1983 when revised Technical Specifications were implemented. Table 3.12-1 of the-Revised Technical Specifications requires collection and analysis of one sample of each commercially and recreationally important species in the vicinity of the station discharge. There is no documentable commercial fishery in Lake Norman, however, there is a substantial recreational fishery based on creel surveys conducted by Duke Power Company in 1979 and 1982. All species of fish identified in the surveys can be divided into roughly three trophic levels: predatory species' (game fish), their forage species and bottom sediment species. There are two basic pathways leading to radionuclide incorporation into fish tissues: ' uptake via_the water column pathway and uptake via the bottom sediments. Because metabolic processes among species of fish do not vary drastically, monitoring species representative of one of each of the-trophic levels mentioned meets the objective of the-sampling requirement for fish samples. Addition of a forage species to the collection program is scheduled for 1984. The control location for milk samples is located 12.5 km/NW and although it is not located within the 15-30 km distance or in the most prevalent wind direction from the station as required by Table 3.12-1 of the McGuire Technical Specifications, the location provides valid background information. Surveys made in an attempt to locate a milk sampling location that complies with the requirements of Table 3.12-1 have failed to identify a more practi-cable location than the one currently being used. Increased attention to the maintenance of automatic samplers during the second half of 1983 has decreased the number of grab samples collected in lieu of the required composite samples. A garden census was performed (the results of which 'are included in Table 6) in lieu of broad leaf sampling at the site boundary in two different direction sectors with the highest predicted D/Q's. _ Lower Limits of Detection Not Achieved Sample Radionuclide Reason A. Commercial Crops 1. (8 mi/N), 7/19/83 I-131 Small quantities of Squash squash, corn, and 2. (8 mi/N), 7/19/83 I-131 tomato samples made Corn count times necessary 3. (8 mi/N), 7/19/83 I-131 to meet I-131 LLD's Tomato unacceptably long. B. Drinking Water 1. (142), 3/5-4/19/83 Zr,95 A McGuire Nuclear Station 2. (131),4/19-5/17/83 Zr-95 Technical, specification revision decreased the re-quired ZR-95 LLD in water samples from 30pci/L to 15pCi/L. The analysis was per-formed from 4/83-6/83 using 30pci/L.

The (136), (142) 4/19-5/17/83 I-131 LLD for I-131 in drinking 5. (131),-(132), water samples in the revised 136), (142) 5/17-6/21/83 I-131 Technical Specifications is 6. 131),(132), 1 pCi/L which is only 136), (142) 6/21-7/19/83 I-131 'achieveable by performing a 7. 131),(132), low-level I-131 analysis. (136), (142) 7/19-8/16/83 I-131 Table 3.12-1 of f1NS Technical 8. (131),(132), Specifications requires an (136),(142)8/16-9/20/83 I-131 1-131 analysis on each monthly 9.

of the water is >l mrem / year. (136), (142) 10/18-11/15/83 I-131 The dose caclulated for II.(131),(132), consumption of water is <1 (136),(142)11/15-12/20/83 I-131 mrem / year and the customary _ gamma analysis LLD of 15 pCi/L for I-131 was used for the required gamma-analyses performed on these samples. C. Surface Water 1. (135), 9/20-10/18/83 I-131 Large sample backlog caused too much decay time between sample collection and count date. Count time necessary to meet I-131 LLD unacceptably long. Tritium concentrations in drinking water and. surface water were closely monitored throughout 1983. No upward increase in tritium' concentrations were observed in drinking water; however, an increase in tritium concentrations in surface water collected from locations 128 and 130 (discharge canal bridge and the Highway 73 bridge immediately downstream respectively) was observed. The increase does not pose a significant health hazard to the public as-the maximum concentration of tritium. reported in surface water represented less than 4% of the MNS Technical Specification 3/4.12.1, Table 3.12-2.
