SUMMARY

During 1993, there were no measurable influences from radioactive effluent releases. Routine measurements continually are taken in the areas surrounding the R.E. Ginna Nuclear Power Plant to determine if man-made radioactivity is released at a level that would cause an influence to the environs surrounding the plant. These measurements detected no measurable activity above established background levels. Samples are collected on an established schedule for regular testing to determine if measurable levels of activity exist that may be attributed to the operation of the plant. The information obtained from measurements of these environmental samples is compared to the calculated levels of potential activity at the sampling locations from normal plant releases as determined by monitors within the plant effluent streams.

Samples of water, air, fallout, fish, vegetation, milk and direct radiation are collected from locations near the plant that were determined to be at the point of highest concentration from releases through the plant and containment vents. Samples are also collected from additional locations at distances ranging out to eighteen miles. Reference samples for background measurements are collected concurrently from locations calculated to have radioactivity concentrations less than 1% of those from the closer sampling locations.

These background samples provide continuous background data which makes it possible to distinguish between significant radioactivity introduced into the environment from the operation of the plant and that introduced from other sources.

During 1993, 1467 samples were collected for 1899 analyses for beta and gamma emitters through gross activity counting techniques and gamma spectroscopy. These total 924 air samples, 301 water samples, 16 fish samples, 9 vegetation samples, 59 milk samples, 2 special. lake samples and 156 thermoluminescent dosimeter measurements. As part of a required quality control program, 9 EPA Interlaboratory Comparison Studies samples (spiked at levels expected to be observed for plant releases) were analyzed and reported.

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

'I 2.0 SURVEILLANCE PROGRAM Regulatory Limits The Technical Specification requirements for the radiological environmental monitoring program are:

Monitorin Pro ram The radiological environmental monitoring program shall be conducted as specified in Table 3.16-1 at the locations given in the ODCM.

If the radiological environmental monitoring program is not conducted as specified in Table 3.16-1, prepare and submit to the Commission, in the Annual Radiological Environmental Operating Report, a description of the reasons for not conducting the program as required 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 Semiannual 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.

Land Use Census A land use census shall be conducted and shall identify the location of the nearest milk 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.

Interlaborator 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, if such a program exists.

(3)

2.2 Regulatory Fulfillment The fulfillment of the Technical Specification requirements shall be demonstrated when:

~Sit The radiological environmental monitoring samples shall be collected pursuant to Table 3.16-1. Acceptable locations are 'shown in the ODCM. Samples shall be analyzed pursuant to the requirements of Tables 3.16-1 and 4.10-1.

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.

2.3 Deviations from the Sampling Schedule Deviations from the sampling schedule are allowed when samples are unavailable due to hazardous conditions, seasonal variations or malfunction of automatic sampling equipment. There were no deviations from the sampling schedule during 1993. The milk sampling schedule was changed during the summer season to adjust to a change in the commercial schedule for milk collection at the farms. The minimum number of samples required in Tech Spec Table 3.16-1 were collected for all pathways.

Table 2-2 Page 2 of 2 LLD TABLE NOTATION The LLD is the smallest concentration of radioactive material in a sample that will yield 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.

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

LLD 4.66 S27 Z V2 22~ 1'xp [(-at) X]

where LLD is the lower limit of detection as defined above (as pCi per unit mass or volume)

Sb is the standard deviation of the background counting rate or of the counting 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) 2.22 is the number of disintegrations per minute per picocurie Y is the fractional radiochemical yield (when applicable) is the radioactive decay constant for the particular radionuclide Q t is the elapsed time between sample collection and analysis for plant effluents.

For environmental samples, sample time is the end of the sampling period.

The value of Sb used in the calculation of the LLD for. a particular measurement system shall be based on the actual observed variance of the background counting rate or the counting rate of the. blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background shall include the typical contribution of other radionuclides normally present in the samples (e.g., potassium-40 in milk samples).

Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally, background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.

i 3.0 DATA

SUMMARY

3.1 Anal tical Results The values listed on the following tables include the uncertainties stated as 2 standard deviations (95% confidence level).

Ke 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.

Cubic Meter (M ): Approximately 35.3 cubic feet.

Liter (L): Approximately 1.06 quarts.

Lower Limit of Detection

' 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. Table 2-3 and 2-4 are a listing of the LLD values for gamma isotopes using our Ge(Li) multichannel pulse height detector system. 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.

Gross detection limits are as follows:

Beta:

Air 0.003 pCi/M gross beta for 400 m sample.

Water 0.7 pCi/L gross beta for 1 liter sample.

Milk 0.45 pCi/L iodine 131 for 4 liter'sample.'.1 Fallout pCi/m /day for 0.092 M'ollection area.

Gamma:

Air 0.03 pCi/m iodine 131 on charcoal cartridge for 400 M sample.

Radiation:5 millirem/quarter for one quarter exposure (TLD).

During 1993 a new intrinsic Ge crystal was purchased for the environmental program. This detector has a higher efficiency and therefore, the LLD values are lower. The variation on the tables of the reported LLD is due to counting samples on the different detectors.

3.2 Air Sam les Radioactive particles in air are collected by drawing approximately one cfm 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 daughter 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. In addition, there is a ring of 5 sampling stations located approximately 7 to 17 miles from the site that serve as background stations.

I Based on weekly comparisons, there was no statistical difference between the on-site and the backgroundradioactive particulate concentrations. The average concentrations for the on-site and background samples were 0.016 and 0.015 pCi/m~ respectively for the period of January to December, 1993. Maximum weekly concentrations for each station were less than 0.028 pCi/m~.

The major airborne activities released from the plant are noble gases, tritium, radioiodines and carbon-14. Most of this activity is released in a gaseous form, however, some radioiodine is released as airborne particulate. For airborne particulates, the average calculated concentration of particulate at the site boundary due to measurable plant releases would be 1.2E-6 pCi/m or 0.019%

of the average release concentration of 6.17E-3 pCi/m~. The survey cannot detect such a concentration which is (0.04% of the LLD of 0.003 pCi/m .

Tables 3-1A, 3-1B are a list of values for the on-site samplers. Tables 3-2A, 3-2B are a list of 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 3-3 A 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 3-4.

Trend plots of the 1993 air filter data with a comparison to the 1992 air filter data are included for both onsite and offsite air monitors. Additionally, a trend plot of the annual averages measured since 1968 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.

3.3 Water Sam les Water samples are collected on a regular schedule from locations surrounding the plant to demonstrate that there is no measurable influence or contamination of drinking or irrigation water from liquid effluent releases or deposition from gaseous effluent releases.

Composite samples are collected weekly from Lake Ontario, upstream (Russell Station) and downstream (Ontario Water District Plant - OWD), and analyzed for gross beta activity. There was no significant difference between the upstream and downstream'sample concentrations. The 1993 averages were 2.66 and 3.06 pCi/liter for the upstream and downstream samples respectively.

Weekly composite samples are taken from the plant circulating water intake (Circ In) and discharge canal (Circ Out). The yearly averages were 2.53 and 2.53 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 biweekly composites of the OWD and the discharge canal is performed.

II For all batch releases, the average concentration in the discharge canal from the identified activity during 1993 was 0.23 pCi/liter. The normal 2 sigma variation for the activity calculation of composite samples is 0.67 pCi/liter or 3 times the average concentration added by releases from the plant.

f Samples of tap water, the nearest well, and the creek which crosses the site are collected and analyzed monthly. The results show no indication of plant influence. Results for all water beta analyses are listed in Tables 3-5A, 3-5B.

Gamma isotopic analysis is done on each monthly sample and each biweekly or monthly composite of weekly samples. These are listed in Tables 3-6 to 3-11 and separated by source-'of sample.

Trend plots are included to show the weekly upstream and downstream beta activities. 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 showing the annual average activity measured during the years 1968 to 1993 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.

Fallout Fallout is a term used to denote radioactive material settling from the atmosphere to the ground. At the sampling stations, the fallout settles as dust or is collected with rainfall by a funnel and bottle. There are two on-site sampling stations and three off-site. Fallout generally increases in the spring months due to transfer of fission products from the upper to the lower atmosphere in conjunction with increased rainfall. The onsite average and the offsite average were 3.24 and 4.31 pCi/m /day respectively. There is no significant difference between on-site and off-site samples for the period of January through December, 1993. Table 3-5C lists the values for fallout samples.

Tritium Anal sis Tritium analysis is done on all water samples on a monthly basis. Composites are made from the weekly composites and a portion distilled for analysis to remove interfering elements or activity. Tritium data is given in Tables 3-12 A

5. B.

iodine Anal sis 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 3-13. Any positive counts and the 2 sigma error are reported. All negative counts after background correction are reported as <LLD for that analysis.

~ 3.4 Milk 3 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 2 sigma error are reported. All negative counts after background correction are reported as <LLD for that analysis. During 1993, no samples indicated positive l-131 activity that exceeded the LLD for the analysis. Table 3-14 is a listing of all samples collected during 1993.

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 Offsite Dose Calculation Manual using equation 13. The calculation is done for releases during the growing season when cows may be grazing. For R.E.

Ginna, this includes only releases during the months of May through October.

The maximum resultant annual thyroid dose for 1993 would be 0.035 mrem using the cow-milk-infant pathway for a hypothetical farm at the site boundary.

Using the real farm with the highest D/Q which is 5 miles from the plant, the maximum calculated dose to the infant is 1.91E-4 mrem from plant releases during the growing season. The annual average plant release rate during the grazing season would give a concentration of < 0.0006 pCi/liter of iodine-131 in milk at this real farm. This concentration is equal to <0.2% of the LLD for this analysis.

3.5 Fi hS Indicator fish are caught in the plume from the Discharge Canal and tested for radioactivity ingested 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 real difference in the activity of the fish caught between the indicator and background locations.

Isotopic gamma concentrations (pCi/wet kilogram) are listed in Tables 3-15A, 3-1 5B.

Samples of algae (cladophora) and sand were obtained from the lake bottom in the discharge plume area. Results of the gamma scan are included in Table 3-16.

Fish are caught by an outside group and were given to us after being held for extended periods for counting by gamma scan. The LLD value for the shorter half life isotopes became large. This is the case for most of the chromium, iodine and barium data in the table. The data is also affected by small fish samples (< 2000 grams) in some species. We have stressed the need to have fish sooner for future samples and holding time has been reduced to less than one week.

3.7 External Penetratin Radiation Thermoluminescent dosimeter (TLD) 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 location ¹7 is influenced by its close proximity to the Contaminated Equipment Storage Area established in 1983 and will normally read 20-40 mRem/quarter. For the year of 1993, omitting location 7, on-site exposure ranged between 9.4 -15.4 mrem/quarter, with an average exposure of 13.4 mrem/quarter and off-site 9.6 - 15.2 mrem/quarter with an average exposure of 12.1 mrem/quarter. Table 3-18 gives TLD readings for each quarter.

A trend chart with a comparison of data for each location for the years of 1992 and 1993 is included. The data plotted is the average quarterly dose measured.

The NRC also obtains TLD measurements around the plant. The following is a comparison of the data for each quarter of 1993 using NRC data from NUREG-0837 Vol. 12, No. 1, 2, 3, and 4. Results in mrem/quarter:

4.0 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 during 1993. The land use remains mainly agricultural in nature. There were several private homes constructed, but no new housing developments or large business construction projects. 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.

A copy of the Land Use Census is attached.

B 5.0 EXTERNAL INFLUENCES During 1993, 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 EPA INTERLABORATORY COMPARISON STUDY An indication of the laboratory's ability to analyze samples and achieve results consistent with other laboratories is the aim of the EPA Interlaboratory Comparison., Selected unknowns are received and analyzed by our procedures and the results are sent to the EPA Environmental Monitoring Systems Laboratory. A report is returned from them indicating the concentrations with which the samples were spiked and how we compared to other laboratories analyzing the same samples. Table 6-1 is a tabulation of the Ginna results of samples analyzed during 1993. Other than 1 sample, gross Beta/Alpha in water for January, the results were good.

A positive bias for beta that existed during 1991 and 1992 was corrected by calibrating the beta counter with a Cs-137 source rather than a Sr-90 source.

A calibration of the gamma detectors with a simulated sample standard corrected an earlier positive bias for gamma analysis.

Graphs showing a statistical analysis of the results of RGS.E's analysis and all reporting laboratories is included after the table. The sigma value is smaller than that calculated by EPA for a single laboratory. The graphs indicate that our agreement with other laboratories for the analysis is good.
