SUMMARY

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 1998 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 1998 results were consistent with data for the past five years and exhibited no adverse trends.

The analytical results from the 1998 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 measurable dose to the general population above natural background levels.

During 1998, 1386 samples were collected for analysis by gross beta counting and/or gamma spectroscopy. These included 879 air samples, 260 water

'amples, 18 fish samples, 16 vegetation samples, 58 milk samples, and 155 thermoluminescent dosimeter measurements.

During 1998 there was 1

deviation from the sampling schedule for TLD's, 7 for air samples, and 2 for water samples. 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.

2.0 PROGRAM DESCRIPTION il 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:

Monitorin Pro ram The radiological environmental monitoring program shall be conducted as specified in Table V-1 at the locations given in the ODCM.

Ifthe 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 ifspecimens are unobtainable due to hazardous conditions, seasonal availability, or to malfunction of automatic sampling equipment.

Ifthe latter, efforts shall be made to complete corrective action prior to the end of the next sampling period.

Ifmilk 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 Radiological Environmental Operating Report which identifies the cause of the unavailability of samples and identifies locations for obtaining replacement samples.

Ifa 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.

Land Use Census 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 offive miles.

D/Q shall be determined in accordance with methods described in the ODCM.

Interlaborato Com arison Pro ram Analyses shall be performed on applicable radioactive environmental samples supplied as part of an interlaboratory comparison program which has been approved by NRC, ifsuch a program exists.

S ecification 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.

Deviations from the Sam lin Schedule 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. Although the Ginna Station environmental laboratory is not currently being used for routine sample analysis, the capability to analyze environmental samples in accordance with the requirements of the Ginna Station Nuclear Emergency Response Plan is maintained.

Table 2-2 Page 2 of 2 LLDTABLE NOTATION The LLD is the smallest concentration of radioactive material in a sample that willyield a net count (above system background) that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

The LLD is defined as an apriori (before the fact) limitrepresenting the capability of a measurement system and not as an aposteriori (after the fact) limitfor a particular measurement, the minimum detectable activity (MDA).

For a particular measurement system (which may include radiochemical separation):

LLD =

4.66 Sb E V 2.22 Y exp(-Xb,t) where:

LLD is the lower limitof detection as defined above (as pCi per unit mass or volume) 4.66 establishes 95% confidence interval about LLD Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (in counts per minute)

E is the counting efficiency (as counts per disintegration)

V is the sample size (in units of mas's or volume) 2.22 is the number of disintegrations per minute per picocurie Y is the fractional radiochemical yield (when applicable)

A, is the decay constant for the particular radionuclide ht is the elapsed time between sample collection, (or end of sample collection period), and time of counting.

3.0 DATA

SUMMARY

3.1 A~li I R IR The values listed on the following tables include the uncertainties stated as

+I-1 standard deviation.

Definitions 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 per second'ubic meter (M3):

Approximately 35.3 cubic feet Liter (L):

Kilogram (Kg):

Approximately 1.06 quarts Approximately 2.205 pounds Lower Limitof Detection The U.S. Nuclear Regulatory Commission has requested that reported values be compared to the Lower Limitof Detection (LLD)for each piece of equipment.

The LLDfor the equipment is established by the measurement'of a blank sample. These values are before 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).

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 are 3 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 each station were less than 0.019 pCi/m'. 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, 3-1B are a list of gross beta analysis values for the on-site samplers.

Tables 3-2A, 3-2B are a list of gross beta analysis 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 performed 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 analyzed 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 1998 Onsite vs. Offsite air filterdata 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 peak activities measured correspond to the years when atmospheric tests of nuclear weapons were being conducted.

~Onsite ~Offsite Peaks are indicative of atmospheric nuclear weapon detonations (25)

3.3 W~t3 Water samples are collected on a schedule from locations surrounding the plant to assess ifthere is any measurable influence upon or contamination of drinking or irrigation water from liquid effluent releases or deposition from gaseous effluent releases.

3 Composite samples are collected weekly from Lake Ontario, upstream (Russell Station) and downstream (Ontario Water District Plant - OWD), composited monthly, and analyzed for gross beta activity. There was no significant difference between the upstream and downstream sample concentrations. The 1998 averages were 2.55 and 2.94 pCi/literfor 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 samples are taken from the plant circulating water intake (Circ In) and discharge canal (Circ Out), and composited monthly. The yearly averages were 2.52 and 2.65 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.

For all batch releases, the average concentration in the discharge canal from the identified activity during 1998 was 6.4 x 10'Ci/liter. The normal a1 sigma variation for the gross beta activity calculation of composite samples is 5.0 x 10'Ci/liter or 10'imes the average concentration added by releases from the plant.

Samples of 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 performed on each monthly sample and on each monthly composite of weekly samples.

These are listed in Tables 3-9 to 3-14 and are separated by source of sample.

26

Tritium Anal sis 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 3-15.

iodine Anal sis All monthly composite water 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 1 sigma error are reported.

During 1998, no sample results indicated l-131 activity that exceeded the LLDfor the analysis. There were no positive iodine-131 results.

~MlkI There are three indicator dairy herds located three to five miles from the plant.

Milksamples 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 analyzed by gamma spectroscopy for major fission products.

All positive counts and the a1 sigma error are reported.

During 1998, no samples indicated l-131 activity that exceeded the LLDfor the analysis.

Table 3-17 is a listing of all samples collected during 1998.

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 1998 would be 1.6 x 10-2 mrem using the cow-milk-infant pathway for a hypothetical 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 8.4 x 10~ mrem from plant releases during the growing season.'8

~Fi hH Indicator fish are caught in the vicinityof the Discharge Canal and analyzed 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 control samples and are prepared in the same manner.

Four different species of fish are analyzed during each half year from the indicator and background locations ifthey are available. There was no statistically significant difference in the activity of the fish caught between the indicator and control locations.

Fish are caught by.R. G. & E. biologists and analyzed by gamma spectroscopy after being held for periods of less than one week. The LLDvalue 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 isotopic analysis are included in Table 3-19.

3.7 External Penetratin Radiation 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 locations ¹7 and ¹13 are influenced by close proximity to the Contaminated Equipment Storage Areas and willnormally read slightly higher than other locations.

For the year of 1998, on-site exposure ranged between 12.3-13.1 mrem/quarter, with an average exposure of 12.7 mrem/quarter and off-site 11.1-12.3 mrem/quarter with an average exposure of 11.6 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, (Environmental Radioactivify, Eisenbud, 1987), and the highest annual total TLD value, (Station 13), of 58.6 millirems yields an annual maximum dose of 4;6 millirems, on-site. The highest annual total TLD value off-site, (Station 18), of 54.6 millirem yields an annual maximum dose of <1 millirem.

Table 3-21 gives TLD readings for each quarter.

1 TLD was missing at the time of collection.

A trend chart with a comparison of data for each location for the years of 1997 and 1998 is included, Table 3-22. The data plotted is the average quarterly dose measured. TLD locations ¹7 and ¹13 were influenced by their proximity to the Contaminated Equipment Storage Area.

'.0 LAND USE CENSUS A land use census is done each year to determine any major changes in the use of the land within 5 miles of the plant. There were no major changes in 1998.

The land use remains mainly agricultural in nature. There were several private homes constructed and a new housing development on Stonebrook Road off Ridge Road 2 miles west of the town of Ontario. 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 September, 1998 is attached.

5.0 EXTERNAL INFLUENCES During 1998, 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.

~ 6.0 INTERLABORATORYCOMPARISON 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, ifsuch 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.

Ginna Station purchases blind spiked samples that are similar to routinely collected environmental water, milk, and air samples. Ginna Station analyzes tritium blind spikes and all other blind spikes are analyzed by JAF Environmental Laboratory (JAFEL). Ginna Station assesses the blind spike analysis by comparing Laboratory result to the vendor's results for agreement accuracy and bias trending.

An assessment of JAFEL for analysis accuracy of the Analytics blind spikes was preformed, using the acceptance test generally referred to as the "NRC" 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:

The ERROR RESOLUTION for all blind spiked samples was 50.6 to 200 which correlates to an upper control limit (UCL) was 1.25 and a lower control limit (LCL) was 0.8. Ifthe comparison ratio falls within the UCL and LCL, the analysis is assessed as agree, and ifnot the assessment is disagree. Comparison trends are assessed for trending within or outside of the UCL of LCL. (See Figures 6.1A, 6.1B, and 6.1C) For 1998, only the tritium comparison ratio fell outside of the LCL, resulting in the tritium trending outside the lower (see Figure 6.1A).

1997 comparison ratios that were outside of the UCL or LCLtrended within the limits for 1998.
