1.0 INTRODUCTION

The preoperational radiological environmental monitoring program for Perry Nuclear Power Plant (PNPP) was initiated in March 1981 and will continue until fuel loading, presently scheduled for June 2, 1985. This program was conducted by NUS Corporation under contract with the Cleveland Electric Illu-minating Company (CEI). This is the fourth Annual Report for the radiological environmental monitoring program being conducted under the contract. This report covers the period December 28, 1983 through October 2, 1984 and summa-rizes the results of measurements and analyses of data obtained from samples collected during this interval. 4 A. Site and Station Description PNPP will consist of two BWR units, each designed to operate at a power level of about 1205 megawatts with the main condenser circulating water cooled by a system of closed-loop natural draft cooling towers. The plant is located on Lake Erie, on approximately 1100 acres, about thirty-five (35) miles north-east of Cleveland, Ohio and about seven (7) miles northeast of Painesville, Ohio. PNPP is situated in North Perry Village in northeastern Lake County, Ohio. B. Objectives and Overview of PNPP Monitoring Program United States Nuclear Regulatory Commission (USNRC) regulations require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA) (10 CFR 50.34). To assure that these criteria are met, each license authorizing reactor operation includes technical specifications (10 CFR 50.36a) governing the release of radioactive effluents. In-plant monitoring will be used to assure that these predetermined release limits are not exceeded. However, as a precaution against unexpected and undefined processes which might allow undue accumulation of radioactivity in any sector of man's environment, a program for monitoring the plant environs is also included. The regulations governing the quantities of radioactivity in reactor effluents allow nuclear power plants to contribute, at most, only a few percent increase above normal background radioactivity. Background levels at any one location are not constant but vary with time as they are influenced by external events such as cosmic ray bombardment, weapons test fallout, and seasonal variations. These levels also can vary spatially within relatively short distances reflect-ing variations in geological composition. Because of these spatial and tempo-ral variations, the radiological surveys of the plant environs are divided into preoperational and operational phases. The preoperational phase of the program of sampling and measuring radioactivity in various media permits a general characterization of the radiation levels and concentrations prevail-ing prior to plant operation along with an indication of the degree of natural variation to be expected. The operational phase of the program obtains data which, when considered along with the data obtained in the preoperational phase, assist in the evaluation of the radiological impact of plant operation. Implementation of the preoperational monitoring program fulfills the following objectives: 1. Evaluation of procedures, equipment and techniques. 2. Identification of potentially important pathways to be monitored after the plant is in operation. 3. Measurement of background levels and their variations along poten-tially important pathways in the area surrounding the plant. 4. Provision of baseline data for statistical comparison with future operational analytical results. Sampling locations were selected on the basis of local ecology, meteorology, physical characteristics of the region, and demographic and land use features of the site vicinity. The preoperational program was designed on the basis of the USNRC Radiological Assessment Branch Technical Position on radiological environmental monitoring as revised in Revision 1 November 1979.II) In 1984 the radiological monitoring program included the measurement of ambient gamma radiation by thermoluminescent dosimetry, the determination of gamma emitters in shoreline sediments and fish, the determination of gross beta and gamma emitters in airborne particulates, the measurement of airborne iodine-131, the measurement of gross beta, tritium, and gamma emitters in water, the measurement of iodine-131 and gamma emitters in milk, the determi-nation of gamma snitters in silage and food products (vegetables), and the measurement of strontium-89 and strontium-90 in milk, water, and sediment. l l

2.0 PROGRAM DESCRIPTION Thirty-nine locations within a radius of about 15 miles from the PNPP site were included in the monitoring program for 1984. The number and locations of monitoring points were determined by considering the locations where the highest off-site environmental concentrations have been predicted from plant effluent source terms, site hydrology, and site meteorological conditions. Other factors considered were applicable regulations, population distribution, ease of access to sampling stations, security and future program integrity. The preoperational environmental radiological program for Perry is sumarized in Table 1. Table 2 describes sample locations, associated media, and approxi-mate distance and direction from the site. Figures 1 and 2 illustrate the locations of sampling stations relative to PNPP. In addition to the described analytical program, a milk animal, vegetable garden, and residence survey was performed in 1984. This survey located the nearest garden and residence in each sector and all milk animals out to 5 miles and will be updated annually. _

i i 1 3.0 SAMPLING METHODS AND PROCEDURES 1 + To derive meaningfJ1 and useful data from the radiological environmental monitoring program, sampling methods and procedures are required which will p'rovide samples representative of potential pathways of the area. During the preoperational phase of the program, samples are collected and analyzed not only to obtain background radiological levels, but at the same time to acquire experience with the sampling methodology and procedural format dictated by site specific requirements.(2) A. Direct Radiation 1 Thermoluminescent dosimeters (TLD's) were used to determine the direct (ambient) radiation levels at twenty-five (25) monitoring points as described in Tables 1 and 2. Sampling locations were chosen according to the criteria given in the USNRC Branch Technical Position on Radiological Monitoring (Revision 1, November 1979)(1) TLDs were located in two rings around the station. An inner ring was located at the site boundary and an outer ring was located at an approximate distance of 4 to 5 miles from the station. The area around the station was divided into 16 radial sectors of 221/2 degrees each. TLDs were placed in all sectors except those which radiated from the site directly out over the lake without intersecting any unrestricted areas. ~ Additional TLDs were located at three nearby communities and two control locations. 1 For routine TLD measurements, two dosimeters of CaSO :Dy in teflon cards 4 were deployed at each selected location. One set of dosimeters was exchanged on a monthly basis and the second set was exchanged on an annual basis. Additional sets of dosimeters were shipped with each exchange cycle to serve as in-transit controls. For routine exchanges TLDs were shipped by overnight t Greyhound one evening, picked up and exchanged the following day, and returned by overnight Greyhound on the second evening. This was done to maintain the minimum possible in-transit dose. - _ _.

Individual dosimeters were calibrated by exposure to an accurately known radiation field from a calibrated Cs-137 source. B. Fish Fish sampling was conducted in May at two locations. The immediate vicinity of the discharge was selected as an indicator location (#25), and an offshore location at Mentor-on-the-Lake (#32) was chosen as a control location. Using a passive collection technique, an experimental gill net (mesh ranging from approximately 1.0 to 2.5 inches to maximize catches in useful size ranges) was set at each sampling location by biologists under contract to NUS Corpora-tion. Nets were set in the evening and removed the following morning. En-trapped surviving fish not required for sampling were released. A Scientific Collecting Permit was obtained from the Ohio Department of Natural Resources to permit this sampling. Available edible species were filleted at the time of collection. The edible portions were packed in dry ice and shipped to the laboratory for analysis by gamma spectrometry. C. Sediment Sediment samples were collected in May at four locations. Two locations were nominally the same as the locations chosen for fish sampling. At Mentor-on-the-Lake (#32) and Perry discharge (#25) the sediment was collected approxi-mately 1 mile offshore. Some movement was necessary to find a suitable sub-strate for sampling. Sediment samples were also collected offshore in the vicinities of Fairport Harbor (#27) and Redbird (#26). Samples were collected with a petite ponar grab sampler in about 30 feet of water. A sample was composited at each location in a plastic container. Approximately I kilogram was frozen and shipped to the laboratory for analysis by gamma spectrometry, and strontium-89 and -90.._ _-_-_.

D. Airborne Particulates/ Iodine-131 Research Appliance Company continuous low volume air sampler units (Model

  1. 209088-2) were used to collect air particulates and airborne iodine-131.

Airborne particulates were collected by drawing air through a 47-millimeter diameter glass fiber filter. Air iodine-131 was collected by drawing air through a 57 millimeter diameter TEDA impregnated charcoal cartride (F & J Specialty Products, Inc.). The sampling units are housed in ventilated metal cabinets bolted to utility poles. The air sampling network consists of six (6) stations; one is located in Redbird (#1) approximately 3.4 miles ENE of the Perry plant and four are located at the site boundary (#3,4,5 and 35). The control location is located at the Concord Service Center (#6), approximately 11 miles SSW of the plant. These locations are identified in Figures 1 and 2 and described in Tables 1 and 2. I The samplers were run continuously and the filter and charcoal cartridge exchanged weekly. The elapsed time of sampling was recorded on an elapsed-l time meter. Total air volume was calculated and recorded by the site techni-cian from the initial and final volumes as registered on the dry gas meter. l E. Water The water sampling network consists of four (4) stations as identified in Figures 1 and 2 and describ'd in Tables 1 and 2. Stations 28 and 34 utilize e Horizon Interval Samplers, which collect a small volume of water at short intervals, nominally 15 minutes. Stations 36 and 37 utilize an interval timer (Dayton #2E357) to control a solenoid valve (Dayton #6X230) on a pres-surized sampling line. This arrangement draws small aliquots at periodic intervals. The small volumes are automatically composited into a five-gallon container. Samples from the four (4) stations are collected monthly by the site technician. -

I F. Milk / Silage Milk samples were collected monthly during the months of January, February, and March, and semi-monthly during the remaining months. The control location, Brookglen Farm (station 33), is located approximately 10.2 miles south of l the Perry plant. The other 3 milk sampling locations are Station 29 (1.4 miles ESE), Station 30 (2.3 miles SSW) and Station 31 (1.4 miles ESE).' Sam-pling from station 31 was begun on February 27, 1984. As a preservative, formalin was added to each sample at the time of collection. The annual -feed / silage sample from stations 29, 30, 31, and 33 was taken on August 13, 1984. G. Vegetables and Food Products The annual collection of food products (various fruits and vegetables) was conducted on July 25, 1984 from Station 38 and August 9, 1984 from Station 39. Vegetation samples were not obtained from Station 40 in 1984. l l

4.0 SUW ARY AND DISCUSSION OF 1984 ANALYTICAL RESULTS Data from the radiological analyses of environmental media collected during the report period are tabulated and discussed below. The procedures and specifications followed in the laboratory for these analyses are as required in Section 5.0 Of the NUS Environmental Services Division Quality Assurance Manual, 9019xx-2, and are detailed in the NUS Radiological Laboratory Work Instructions. Radiological analysis of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods.(2) The use of "LT" in the data tables is the equivalent of the less than symbol (<) and is consistent with the NUS Radiological Laboratory practice of data reporting. The number following the "LT" is a result of the lower limit of detection (LLD) calculation as defined in Appendix B. "ND" (Not Detected) is used periodically in the tables presentira gama analysis results for various media. It primarily appears under the "Others" column, and indicates that no other detectable gama emitting nuclides were identified. NUS analytical methods meet the " a priori" LLD requirements addressed in Table 2 of the USNRC Branch Technical Position on Radiological Monitoring (November 1979, Revision 1).(1) Tables 3 through 19 give the radioanalytical results for individual samples. A statistical sumary of the results appears in Table 20. The reported averages are based only on concentrations above the limit of detection. In Table 20, the fraction (f) of the total number of analyses which were detectable follows in parentheses. Also given in parentheses are the minimum and maximum values of detectable activity during the report period. l A. Direct Radiation Environmental radiation dose rates determined by thermoluminescent dosimeters (TLDs) are given in Table 3. Average monthly dose rates are plotted in Figure 3. TLD badges of four readout areas each were deployed at each location f on monthly and annual cycles. The " annual" cycle covers the period January

!o through August. The mean values of four readings (corrected individually for response to a known dose and for in-transit exposure) are reported. A statistical summary of the 1984 data is included in Table 20. Individual measurements of external radiation levels in the environs of the PNPP site ranged from 0.07 to 0.37 mR/ day. Table 4 compares the data from the annual cycle TLDs with the annual averages of the monthly cycle TLDs. Agreement between the two types of data is generally quite good. Annual averages (from the monthly cycles) ranged from 0.17 to 0.29 mR/ day or 62 to 106 mR/ year. Oakley(3) calculates an ionizing radiation dose equivalent of 82.2 mR/ year for Ohio including a terrestrial component of 45.6 mR/ year and an ionizing cosmic ray component of 36.6 mR/ year (excludes neutron component). Since Oakley's values reprasent averages covering wide geographical areas, the measured ambient radiation average of 77 mR/ year for the immediate locale of Perry is not inconsistent with Dakley's observations. Significant variations occur between geographical areas as a result of geological composition and altitude differences. Temporal variations result from changes in cosmic ray intensity, local human activities, and factors such as ground cover and soil moisture. B. Fish The results of ganrna spectrometric analyses of fish samples collected during 1984 are presented in Table 5. The averages, fraction of detectables, and range of radionuclide concentrations are summarized in Table 20. A total of 9 samples were analyzed; 5 from the indicator location (#25) and 4 from the control location (#32). Sampling efforts concentrated on the larger edible species of commercial and/or recreational importance. Naturally occurring K-40 was the only detectable activity in the edible portions of the fish, i -

4 C. Sediment i The processes by which radionuclides and stable elements are concentrated in bottom sediments are complex, involving physicochemical interaction in the environment between the various organic and inorganic materials from the watershed. These interactions can proceed by a myriad of steps in which j the elements are adsorbed on or displaced from the surfaces of colloidal particles enriched with chelating organic materials. Biological action of bacteria and other benthic organisms also contribute to the concentration of certain elements and in the acceleration of the sedimentation process. Results of the gamma isotopic and strontium analyses of the sediments sampled from the PNPP environment are given in Tables 6 and 7, respectively. The average, fraction of detectables, and range of radionuclide concentrations l are sunnarized in Table 20. Most of the observed gamma emitters were naturally occurring members of the uranium and thorium decay chains. These were detected in their expected concentrations. Similarly, K-40 was observed in all samples at its expected range of activities. Due to the inhomogeneity typical of sediment samples, wide variations between samples are expected even when the samples are taken relatively near each other. Strontium-89 and strontium-90 results are presented in Table 7. There was no detectable strontium-89 or strontium-90 activity in the samples. i D. Air Particulates/ Iodine - 131 i The results of the gross beta analyses on air particulate filters are presented in Table 8. Average weekly gross beta results are plotted in Figure 4. A total of 191 analyses were performed; 159 from the indire t.or locations and 32 from the control location. Both the indicator and control locations 3 j had mean gross beta activities of 17 E-03 pCi/m. The range of gross beta 3 i activity for the indicator and control locations was 4.7 to 32 E-03 pCi/m 3 and 5.7 to 34 E-03 pCi/m, respectively. 1.

Air filters were composited quarterly and analyzed by gamma spectrometry. The gamma spectrometry results are-presented in Table 9. A total of 12 composite analyses were performed; 10 from the indicator locations and 2 from the control location. Cosmogenic beryllium-7 was the only isotope detected. Be-7 was found in 12 of 12 samples analyzed. Airborne iodine-131 analyses on charcoal cartridges were also performed and the results are presented in Table 10. Iodine-131 was not detected in any of the samples. E. Water The results of the gamma spectrometric analyses of water samples are presented in Table 11. There were 28 analyses performed; 21 from the indicator locations and 7 from the control location. There was no detectable activity in any of the sampler analyzed. The 28 water samples were also analyzed for gross beta activity. The average gross beta activity for the indicator and control locations was 3.4 pCi/l and 3.5 pCi/1, respectively. Results of gross beta analyses are given in Table 12. Water samples were also composited quarterly for the tritium analysis. The quarterly results are presented in Table 13. Positive tritium activity was detected in 6 out of 12 samples. The average tritium activity for the indicator and control locations was 290 pC1/1 and 240 pCi/1, respectively. These activi-ties (pC1/1) were well below the LLD as defined in the USNRC Branch Technical position on Radiological Monitoring (November 1979, Revision 1(1)) Strontium-89 and strontium-90 analyses were performed on February and May, 1984 water samples. Positive strontium-90 activity (1.4 + 0.5 pC1/1) was detected in one February sample from station 36. Results are presented in Table 14. Positive strontium-89 activity was detected in one February sample from station 34 and a confirmatory analysis was scheduled. However, an insuf-ficient amount of sample remained for re-analysis. No data is reported here for this station since the results could not be confirmed. - -. - -

Milk / Silage Milk samples were analyzed by gama spectrometry and the results are presented in Table 15. Three indicator locations and one control station were sampled during 1984. There were 47. analyses performed, and as expected, K-40.was the major detectable activity. Cesium-137 was detected in 5 of 35 samples from the indicator locations and 1 of 12 samples from the control location. Cs-137 activity ranged from 1.7 to 4.4 pCi/1. Because of its presence on global fallcut, Cs-137 is often observed in milk samples at these activity levels. The milk samples were also analyzed for iodine-131 and, as expected, there was no detectable activity. The I-131 results are presented in Table 16. Strontium-89 and strontium-90 analyses were performed on February and May, 1984 milk samples. Results are presented in Table 17. There was no strontiur-89 detected in the milk samples. Strontium-90 was detected in all February milk samples with activities ranging from 0.47 pCi'l to 1.3 pCi/1. Feed / Silage samples were collected in August from the 4 milk stations and analyzed by gama specirometry. These results are presented in Table 18. Naturally occurring K-40 was observed in all of the samples. Cosmogenic Be-7 was observed in 4 of 8 samples due to its deposition as stratospheric fallout. G. Vegetables and Food Products Vegetables and fruits were collected in July and August from 2 indicator locations and analyzed by gama spectrometry. The results are presented in Table 19. Naturally occurring K-40 was detected in all of the vegetation samples at its expected range of activity. i ).

5.0 LAND USE CENSUS A land use survey was performed in the environs of the Perry NPP on July 9th and July 10th 1984(4) The purpose of thir survey was to identify the potential indicator milk sampling locations as well as the nearest vegetable garden and residence in each of the sixteen standard sampling sectors around the plant. The outer bound of the survey for identifying the " nearest" or potential indicator locations was 5 miles. In addition, candidate " control" milk sampling locations were verified. Table 21 identifies the nearest garden and residence in each sector for which one could be identified within the 5 mile radius. Table 22 identifies all the potential indicator milk sampling locations within 5 miles of the plant. Control milk sampling locations are given in Table 23.

APPENDIX A LABORATORY QUALITY ASSURANCE 1. Introduction The quality assurance program of the Radiological Laboratory of NUS is briefly described in this appendix. Information on each incoming sample is entered in a permanent log book. A sample number is assigned to each sample at the time of receipt. This sample number uniquely identifies each sample. Laboratory counting instruments are calibrated, using radionuclide standards obtained from the National Bureau of Standards, the EPA, and reliable commer-cial suppliers, such as Amersham-Searle. Calibration of counting instruments is maintained by regular counting of radioactive reference sources. Background counting rates are measured regularly on all counting instruments. Additional performance checks for the gamma-ray scintillation spectrometer include regular checks and adjustment, when necessary, of energy calibration. Blank samples are processed, with each group of samples analyzed for specific radionuclides, using radiochemical separation procedures. Blank, spiked (known quantities of radioactivity added), and replicate samples are processed periodically to determine analytical precision and accuracy. 2. Laboratory Analyses for Quality Assurance The tuality assurance procedures employed in the conduct of radiological monitoring programs by the Environmental Services Division Radiological Labora-tory are as required in the Division Quality Assurance Manual and detailed in the NUS Radiological Laboratory Work Instruction. These procedures include the requirement for (1) laboratory analysis of samples distributed by appropri-ate government or other standards-maintaining agencies in a laboratory inter-comparison program, (2) analysis of some of the client's environmental samples 1 -r,- x

APPENDIX B REPORTING 0F ANALYTICAL RESULTS In the tables presenting analytical measurements, the calculated value is reported with the two sigma counting error (2s) derived from a statistical analysis of both the sample and background count rates. The precision of the results ir influenced by the size of the sample, the background count rate, and the method used to round off the value obtained to reflect the degree of significance of the results. For analytical results obtained from gamma spectral analysis, the precision is also influenced by the composition and concentrations of the radionuclides in the sample, the size of the sample, and the assumptions used in selecting the radionuclides to be quantitatively determined. The two sigma error for the net counting rate. is: [R R)1/2 s b 2s = 2i p* + 7 l k / Where: R = sample counting rate s Rb = background counting rate 3 t = sample counting time s tb = background counting time If the measurements on the samples are not statistically significant (i.e., the two sigma count error is equal to or greater than the net measured value), then the radioactivity concentrations in the samples are considered not de-tected. Results reported as less than ("LT") are below the lower limit of detection (LLD). The LLD is defined as the smallest concentration of radioactive mate-rial in a sample that will yield a net count (above system background) that will be detected with 95 percent probability with only 5 percent probability of falsely cor.cluding that blank observation represents a "real" signal. J

E. For a particular measurement system (that may include radiochemical separation): 4.66s l b E x V x 2.22 x Y x exp (-A at) I LLD = l a where: LLD is the lower limit of detection as defined above (as pCi per unit mass or volume) s is the standard deviation of the background counting rate or b of the countir,g rate of a blank sample as appropriate (as counts per minute) ~ E is the counting efficiency (as counts per disintegration) V is the sample size (in units of mass or volume) e 2.22 is the number of disintegrations per minute per picocurie i I Y is the fractional radiochemical yield (when applicable) 1, f ^ l A is the radioactive-decay constant for the particular radionuclide i l At is the elapsed time between the end of sample collection and counting The following are definitions or descriptions of; statistical terms used in the reporting and analysis of environmental monitoring results. Precision relates to the reproducibility of measurements within a set, that is, to the scatter or dispersion of a set about its central value. Measures of thg Central Value of a Set. Mean (or Average or Arithmetic Mean) is the sum y) X of the values of individual results divided by the g number of results in the set. The mean is given by: X = (X1+X2 +... X ) / " " i 1 n

i Measures of Precision with a Set. Standard Deviation is the square root of the quantity (sum of squares of deviations of individual results from - the mean, divided by one less than the number of results in the set). The standard deviation, s, is given by: (Xg - i) / (n-1) s= 1 Standard deviation has the same units as the measurement. It becomes a more reliable expression of precision as n becomes larger. When the measurements are independent and normally distributed, the most useful statistics are the mean for the central value and the standard deviation for the dispersion. Note: In the USEPA Intercomparison Program, the standard deviation given by EPA is for the expected laboratory result from three analyses. The standard l deviation given by NUS is the standard deviation from the mean of three report-ed values. Relative Standard Deviation is the standard deviation expressed as a fraction of the mean, s/i. It is sometimes multiplied by 100 and expressed as a percent-age. I-Rance is the difference in magnitude between the largest and the smallest results in a set. Instead of a single value, the actual, limits are sometimes expressed (minimum value/ maximum value). l l
