SUMMARY

RADIOLOGICAL ENVIRONMENTAL SURVEY January 1-December 31, 1997 The Annual Radiological Environmental Operating Report is published in accordance with Section Vl of the Offsite Dose Calculation Manual, (ODCM).This report describes the Radiological Environmental Monitoring Program, (REMP), and its implementation as required by the ODCM.The REMP is implemented to measure radioactivity in the aquatic and terrestrial pathways.The aquatic pathways include Lake Ontario fish, Lake Ontario water, and Deer Creek water.Measurement results of the samples representing these pathways contained only natural background radionuclides or low concentrations of Cs-137 resulting from past atmospheric nuclear weapons testing.The 1997 results were consistent with data for the past five years and exhibited no adverse trends.Terrestrial pathways were also monitored.

These included airborne particulate and radioiodine, milk, food products, and direct radiation.

Analysis of terrestrial pathways demonstrated no detectable increase in radiation levels as a result of plant operation.

The 1997 results were consistent with data for the past five years and exhibited no adverse trends.The analytical results from the 1997 Radiological Environmental Monitoring Program demonstrate that the operation of the Robert E.Ginna Nuclear Power Station had no measurable radiological impact on the environment.

The results also demonstrate that operation of the plant did not result in a dose to the general population above natural background levels.During 1997, 1454 samples were collected for analysis by gross beta counting and gamma spectroscopy.

These included 928 air samples, 292 water samples, 16 fish samples, 7 vegetation samples, 58 milk samples, and 153 thermoluminescent dosimeter measurements.

During 1997 there were 3 deviations from the sampling schedule for TLD's and 9 for tritium analysis.The minimum number of samples required in ODCM Table V-1 were collected for all pathways.Samples were collected by Ginna Station chemistry personnel and analyzed by the J.A.Fitzpatrick Nuclear Power Plant Environmental Laboratory.

A summary of the data collected indicating the results of all data for indicator and control locations is given in Table 1-1.

2.9 PROGRAM

DESCRIPTION

2.1 Program

Objectives The objectives of the Radiological Environmental Monitoring Program are:~Measure and evaluate the effects of plant operation on the environment.

~Monitor background radiation levels in the environs of the Ginna site.~Demonstrate compliance with the environmental conditions and requirements of applicable state and federal regulatory agencies, including the ODCM and 40 CFR 190.~Provide information by which the general public can evaluate environmental aspects of the operation of Ginna Nuclear Power Station.2.2 Program Requirements In order to achieve the objectives listed in section 2.1, a sampling and analysis program is implemented each year according to table V-1 of the ODCM.Following are the requirements from the ODCM: Mon'r'o ram The radiological environmental monitoring program shall be conducted as specified in Table V-1 at the locations given in the ODCM.If the radiological environmental monitoring program is not conducted as specified in Table V-1, prepare and submit to the Commission, in the Annual Radiological Environmental Operating Report, a description of the reasons for these deviations and the plans for preventing a recurrence.

Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal availability, or to malfunction of automatic sampling equipment.

If the latter, efforts shall be made to complete corrective action prior to the end of the next sampling period.If milk or fresh leafy vegetable samples are unavailable for more than one sample period from one or more of the sampling locations indicated by the ODCM, a discussion shall be included in the Annual Radioactive Effluent Report which identifies the cause of the unavailability of samples and identifies locations for obtaining replacement samples.If a milk or leafy vegetable sample location becomes unavailable, the locations from which samples were unavailable may then be deleted from the ODCM, provided that comparable locations are added to the environmental monitoring program.

La Us C su A land use census shall be conducted and shall identify the location of the nearest milk producing animal and the nearest residence in each of the 16 meteorological sectors within a distance of five miles.An onsite garden located in the meteorological sector having the highest historical D/Q may be used for broad leaf vegetation sampling in lieu of a garden census;otherwise the land use census shall also identify the location of the nearest garden of greater than 500 square feet in each of the 16 meteorological sectors within a distance of five miles.D/Q shall be determined in accordance with methods described in the ODCM.labo on ro a Analyses shall be performed on applicable radioactive environmental samples supplied as part of an interlaboratory comparison program which has been approved by NRC, if such a program exists.c c I The radiological environmental monitoring samples shall be collected pursuant to, Table V-1.Acceptable locations are shown in the ODCM.Samples shall be analyzed pursuant to the requirements of Tables V-1 and V-3.A land use census shall be conducted annually (between June 1 and October 1).A summary of the results obtained as part of the required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Operating Report.Devi'Deviations from the sampling schedule are allowed when samples are unavailable due to hazardous conditions, seasonal variations or malfunction of automatic sampling equipment.

During the last quarter of 1996, the analysis of environmental samples was transferred to the James A.FitzPatrick Environmental Laboratory.

The ability to do analyses still exists, but the Ginna lab is not currently used for routine environmental sample analyses.

3.0 DATA

SUMMARY

3 1 Ana'ca Is The values listed on the following tables include the uncertainties stated as a 1 standard deviation.

e Defiio s Curie (Ci): The quantity of any radionuclide in which the number of disintegrations per second is 37 billion.Picocurie (pCi): One millionth of a millionth of a curie or 0.037 disintegrations persecond.

Cubic Meter (M'): Approximately 35.3 cubic feet.Liter (L): Kilogram (Kg): Lo D Approximately 1.06 quarts.Approximately 2.205 pounds.The Nuclear Regulatory Commission has requested that reported values be compared to the Lower Limit of Detection (LLD)for each piece of equipment.

The LLD for the equipment is established by the measurement of a blank sample.These values are before the correction for decay.Decay correction is applied from the end of the sampling period to the counting time, not from the midpoint of the sampling period.An explanation of the calculation of the LLD is included with Table 2-2, (page 8).

3.2~S Radioactive particles in air are collected by drawing approximately one scfm through a two inch diameter particulate filter.The volume of air sampled is measured by a dry gas meter and corrected for the pressure drop across the filter.The filters are changed weekly and allowed to decay for three days prior to counting to eliminate most of the natural radioactivity such as the short half-life progeny products of radon and thoron.The decay period is used to give a more sensitive measurement of long-lived man-made radioactivity.

A ring of 6 sampling stations is located on the plant site from 150 to 300 meters from the reactor near the point of the maximum annual average ground level concentration and 1 additional at 690 meters.In addition, there is a ring of 5 sampling stations located approximately 7 to 17 miles from the site that serve as control stations.Based on weekly comparisons, there was no statistical difference between the on-site and the off-site radioactive particulate concentrations.

The average concentrations for the on-site and off-site samples were 0.017 and 0.016 pCi/m'espectively for the period of January to December, 1997.Maximum weekly concentrations for each station were less than 0.037 pCi/m', with the exception that Station 13 on the week of June 16, 1997 measured at 0.062 pCi/m'.The composite gamma spectrum for Station 13 during this period showed no elevated level of radioactivity.

The major airborne activities released from the plant are noble gases, tritium and radioiodines.

Most of this activity is released in a gaseous form, however, some radioiodine is released as airborne particulate.

Tables 3-1A, 3-1 B are a list of gross beta analyses values for the on-site samplers.Tables 3-2A, 3-2B are a list of gross beta analyses values for the off-site samplers.The particulate filters from each sampling location were saved and a 13 week composite was made.A gamma isotopic analysis was done for each sampling location and corrected for decay.The results of these analyses are listed in Tables 3-4A to D.Iodine cartridges are placed at six locations.

These cartridges are changed and counted each week.No positive analysis was found on any sample.A list of values for these cartridges is given in Table 3-5.A trend plot of the 1997 Onsite vs.Offsite air filter data is included, Table 3-3.Additionally, a trend plot of the annual averages measured since 1968, Table 3-6, is included to show the variation of data during the years that the R.E.Ginna Nuclear Power Plant has been operational.

The 1997 averages were 2.45 and 2.69 pCi/liter for the upstream and downstream samples respectively.

A graphical comparison of upstream vs downstream gross beta analysis results is given in Table 3-7A.Peaks up to 5 pCi/liter occur when the lake is stirred up by wind and the sample includes large quantities of suspended silt.A trend plot, Table 3-7 B, showing the annual average activity measured during the years since 1968 is included to show the data during the years the R.E.Ginna Nuclear Power Plant has been in operation.

The peaks correspond to the years when atmospheric testing of nuclear weapons occurred.Weekly composite samples are taken from the plant circulating water intake (Circ In)and discharge canal (Circ Out).The yearly averages were 2.69 and 2.44 pCi/liter for the intake and discharge canal respectively.

These are essentially the same as the upstream and downstream values as they fall within the+2 sigma error band and range of the measurement.

A gamma isotopic analysis of monthly composites of the OWD and the discharge canal was performed.

For all batch releases, the average concentration in the discharge canal from the identifie activity during 1997 was 3.8x10'Ci/liter.

The normal a1 sigma variation for the activity calculation of composite samples is 0.48 pCi/liter or 104 times the average concentration added by releases from the plant.Samples of tap water and the creek which crosses the site are collected and analyzed monthly.The results show no indication of plant influence.

The higher average gross beta values for Deer Creek are attributed to higher levels of Radon progeny in the soils from which the creek recharges and over which the creek flows.Results for all water beta analyses are listed in Tables 3-8.Gamma isotopic analysis is done on each monthly sample and each monthly composite of weekly samples.These are listed in Tables 3-9 to 3-14 and are separated by source of sample.Since these are decay corrected from the end of the sample period, short half-life elements such as Ba-La may not meet the required LLD.(26)

Tn U a sls Tritium analysis was performed on all water samples on a monthly basis.Composites are made from the weekly composites and a portion distilled for analysis to remove interferences.

Tritium data is given in Table 3-1 5.The supplemental tritium samples, (Deer Creek and tap water), were temporarily deleted from the sample schedule from January through May.Subsequently, tap water was permanently deleted as redundant with Ontario Water District.eA al's All monthly composite water samples except the fallout samples are analyzed for iodine-131.

The analysis allows the determination of iodine-131 activity of<1 pCi/liter.

iodine data is given in Table 3-16.Any positive counts and the 2 sigma error are reported.All negative counts after background correction are reported as<LLD for that analysis.There were no positive iodine-131 results.

~3.4~lk S There are three dairy herds located three to five miles from the plant.Milk samples are collected monthly during November through May from one of the three and biweekly during June through October from each.A control farm sample is taken for each monthly sample and once during each biweekly period.The milk is analyzed for iodine-131 and also gamma scanned for major fission products.All positive counts and the a1 sigma error are reported.All negative counts after background correction are reported as<LLD for that analysis.During 1997, no samples indicated positive l-131 activity that exceeded the LLD for the analysis.Table 3-17 is a listing of all samples collected during 1997.The annual dose to the thyroid of an infant which could result from the measured plant release rate was calculated by the method described in the ODCM.The calculation was done for releases during the growing season when cows may be grazing.For Ginna Station, this includes only releases during the months of May through October.The maximum resultant annual thyroid dose for 1997 would be 0.25 mrem using the cow-milk-infant pathway for a hypthetical farm at the site boundary.Using the farm with the highest D/Q which is 5 miles from the plant, the maximum calculated dose to the infant would be 1.35x10~mrem from plant releases during the growing season.(39)

3.5 Indicator

fish are caught in the vicinity of the Discharge Canal and tested for radioactivity from liquid effluent releases from the plant.The fish are filleted to represent that portion which would normally be eaten.Additional fish are caught more than 15 miles away to be used as background indicators and are prepared in the same manner.Four different species of fish are analyzed during each half year from the indicator and background locations if they are available.

There was no statistically significant difference in the activity of the fish caught between the indicator and background locations.

Fish are caught by R.G.8 E.biologists and counted by gamma spectroscopy after being held for periods of less than one week.The LLD value for the shorter half life isotopes became greater.The data could also be affected by small mass samples, (<2000 grams), in some species.Isotopic gamma concentrations (pCi/kilogram wet)are listed in Tables 3-18A, 3-18B.Samples of algae (cladophora) and sand, (benthic sediment), were obtained from the lake bottom in the discharge plume area.Lake bottom samples continue to show small amounts of Cs-137 activity.Results of the gamma scans are included in Table 3-19.

~~3.7 e a e era i Radia ion Thermoluminescent dosimeters, (TLD's), with a sensitivity of 5 millirem/quarter are placed as part of the environmental monitoring program.Thirty-nine TLD badges are currently placed in four rings around the plant.These rings range from less than 1000 feet to 15 miles and have been dispersed to give indications in each of the nine land based sectors around the plant should an excessive release occur from the plant.Badges are changed and read after approximately 3 months exposure.TLD locations¹7 and¹13 are influenced by close proximity to the Contaminated Equipment Storage Areas and will normally read slightly higher than other locations.

For the year of 1997, on-site exposure ranged between 10.5-16.2 mrem/quarter, with an average exposure of 13.2 mrem/quarter and off-site 10.1-14.1 mrem/quarter with an average exposure of 11.9 mrem/quarter.

40 CFR 190 requires that the annual dose equivalent not exceed 25 millirems to the whole body of any member of the public.Using 54 millirems average ambient radiation,(Environmenfal Radioactivify, Eisenbud, 1987), and the highest annual total TLD value, (Station 7), of 61.5 millirems yields an annual maximum dose of 7.5 millirems.

Table 3-21 gives TLD readings for each quarter.3 TLD's were missing at the times of collection.

A trend chart with a comparison of data for each location for the years of 1996 and 1997 is included, Table 3-22.The data plotted is the average quarterly dose measured.TLD location¹13 for 1996 was influenced by its proximity to the Contaminated Equipment Storage Area.(47)

A new Tops Supermarket was under construction at the southeast corner of Furnace Road and Highway 104, scheduled to open for business in March, 1998.The three dairy operations nearest the plant continued in operation with an average of 40 to 70 milking cows.There are no goats used for milk on a regular basis within the 5 mile radius.Beef cattle are still raised on 3 farms within 2 miles of the plant as in the past.An onsite garden is used for the broad leaf vegetation and onsite crops are collected for indicator samples when available.

A copy of the Land Use Census that was completed during August and September, 1997 is attached.5.0 EXTERNAL INFLUENCES During 1997, there were no external influences such as atmospheric weapons testing or accidents at other nuclear facilities which caused an influence on the data reported.The annual trending graphs for air and water indicate a level effect in the measured activity.Rochester Gas and Electric Corporation, in cooperation with the University of Rochester, is currently pursuing a research project to identify and quantify sub-trace levels of long lived radionuclides in the environs of western New York, and to identify their sources and migration pathways.(50)

6.0 INTERLABORATORY

COMPARISON STUDY Participation in an interlaboratory comparison program ensures that independent checks for bias and accuracy of the measurement of radioactive material in environmental samples are performed as part of a quality assurance program for environmental monitoring.

The ODCM requires participation in an interlaboratory comparison program that is approved by the NRC, if such a program exists.Until 1996 the United States Environmental Protection Agency (EPA), Office of Research and Development, National Exposure Research Laboratory, Las Vegas, Nevada, was the NRC approved program.Since the NRC has not approved a replacement for the EPA's program, Ginna Station has engaged the services of an independent laboratory, Analytics, Inc., Atlanta, Georgia.The Analytics Environmental Cross-Check Program supplies sample media that is similar to routinely collected environmental water, milk, and air samples, as blind spikes at levels of radioactivity appropriate for environmental monitoring.

The blind spikes are received by Ginna Station and shipped to JAF Environmental Laboratory (JAFEL)for analysis with routine samples.Ginna Station assesses JAFEL's analysis after receiving Analytics Report that compares the JAFEL to Analytics results.An assessment of JAFEL for analysis bias of the Analytics blind spikes is not possible at this time, since during the first year of the program the baseline history for evaluating a bias is established.

An assessment of JAFEL for analysis accuracy of the Analytics blind spikes was preformed, using the acceptance test generally referred to as the ANRCO method.This method is contained in NRC Procedure DVP-04.01 and was taken from the Criteria of Comparing Analytical Results (USNRC)and Bevington, P.R., Data Reduction and Error Analysis for the Physical Sciences, McGraw-Hill, New York, (1969).The accuracy evaluation is as follows: R<<R I Ii=A~li V I P p I~II=JAFRI V I Analytics Uncertainty Analytics Value Using the appropriate row under the ERROR RESOLUTION column in Table 6.1, a corresponding RATIO OF AGREEMENT interval is used as the acceptance criteria for the comparison ratio.(53)
