RADIOLOGICAL ENVIRONMENTAL SURVEY Zanua December 1991 SU1QGGtY During
- 1991, there were no
.measurable influences from radioactive effluent releases.
Routine measurements are taken in the areas surrounding the R.E.
Ginna Nuclear Power Plant to determine if man-made
- radioactivity is being released at a level that would cause an influence to the
,,environs surrounding.the plant.
Samples are collected onan 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 concentra-tion from releases through the plant and containment vents and 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
- 1991, 1670 samples were obtained and analyzed for beta and gamma emitters through gross activity counting techniques and gamma spectroscopy.
These total 892 air
- samples, 488 water
- samples, 16 fish samples, 8 vegetation samplesg 112 milk samples and 154 thermoluminescent dosimeter measurements.
As part of a required quality control program, 12 EPA Interlaboratory Comparison Studies samples (comparable to normal samples taken by the environmental program) 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.

SURVEILLANCE PROGRAM 2 ~ 1 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 prevent-ing 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'he 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.

3.0 DATA
SUMMARY
3.1 Anal tical Results The values listed on the following tables include the uncertainties stated as 2 standard deviations (954 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.
Table 2-1 is 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.
An explanation of the calculation of the LLD is included before Table 2-1.
Gross detection limits are as follows:
Beta:
Air Nater Milk Fallout 0.003 pCi/M gross beta for 400 m
sample.
1.2 pCi/L gross beta for 1 liter sample.
0.20 pCi/L iodine 131 for 4 liter sample.
1.1 pCi/m /day for 0.092 M collection area.
Gamma:
Air 0.03 gCi/m iodine 131 on charcoal cartridge for 400 M
sample.
Radiation:5 millirem/quarter for one quarter exposure (TLD).

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 radio-activity.
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.
Based on weekly comparisons, there was no statistical difference between the on-site and the background radioactive particulate concentrations.
The average concentrations for the on-site and background samples were 0.018 and 0.017 pCi/m3 respectively for the period of January to December, 1991.
Maximum weekly concentrations for each station were less than 0.034 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. 'or airborne particulates, the.average calculated concentration of particulate at the site boundary due to measurable plant releases would be 8.0E-5 pCi/m or 0.0194 of the average release concentration of 0.447 pCi/m The survey cannot detect such a concentration which is <34 of 'the LLD of 0.003 pCi/m3.
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 four locations.
These cartridges are changed and counted each week.
A list of values for these cartridges is given in Table 3-4.
During late 1990 and
- 1991, a sampler placed at location g9 had a
low sample flow rate and the calculated LLD exceeded the required LLD of 0.07 pCi/cu meter.
The calculated LLD was normally (
0.085 pCi/cu meter.
The sampler was replaced during normal annual maintenance in December 1991.
Station Illexceeded the required LLD for 3 weeks during and after the March ice storm when the sampler operated for short intermit-tent periods.until the breaker..could be repaired.
Trend plots of the 1991 air filter data with a comparison to the 1990 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.

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 licpxid 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 1991 averages were 2.34 and 2.36 pCi/liter for the upstream and downstream samples respectively.
Weekly'omposite samples are taken from the plant circulating water intake (Circ In) and discharge canal (Circ Out).
The yearly averages were 2.48 and 2.56 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.
For all batch
- releases, the average concentration in the discharge canal from the identified activity during 1991 was 0.26 pCi/liter.
The normal 2
sigma variation for the activity calculation of composite samples is 0.72 pCi/liter or 3 times the average...concentration added by releases from the plant.
P 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 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.
A trend plot showing the annual average activity measured during the years 1968 to 1991 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 4.54.and,.4.18 pCi/m /dayrespectively..
Based on the two 'sigma error of the measurement,.
there was no significant difference between on-site and off-site samples for the period of January through December, 1991.
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
B.
All positive counts and the 2
sigma error are reported.
All negative counts after background correction are reported as
<LLD for that months analysis.
Iodine Anal sis All monthly composite water
-samples except the fallout samples are analyzed for Iodine-131.
The analysis is done by chemical separation using an added carrier solution and gross beta counting.
The analysis allows the determination of Iodine-131 activity of 1 pCi/liter.
Iodine data is given in Table 3-13.
All -positive counts and the 2
sigma error are reported.
All negative counts after background correction are reported as (LLD for that analysis.
The average for positive values from indicator samples is 0.129+0.07 and for background samples is 0.168+0.129.
The normal LLD for the analysis is 0.20.

3.4 Milk Sam les 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.
The method involves chemical separation of iodine and gross beta counting.
The counting procedure is not specific for Iodine-131 and other isotopes may add to the count rate.
-All positive counts and the
- 2. sigma error are reported.
All negative counts after background correction are reported as
<LLD for that analysis.
The average for all positive values from indicator farms is 0.142+0.080 and from the background farm is 0.127+0.080.
During
,'analysis.
.One sample from farm C exceeded the required LLD of 1 pCi/liter when the yield for the separation was 124.
Table 3-14 is a listing of all samples collected. during 1991.
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 1991 would be 0.55 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
.0.0070. mrem from plant releases during the growing season.
The annual average plant release rate during the grazing season would give a concentration of
< 0.0422 pCi/liter of Iodine-131 in milk at this real farm.
This concentration is equal to 1/15 of the LLD for this analysis.

3.5 Fish Sam les 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, 3-15B.
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.
Most fish are held for extended periods before being counted by gamma scan.
The LLD value for the shorter half life
isotopes will become large.
This is the case for most of the
This data is also affected by small fish samples in some species.

It had been determined that.small releases were occurring from the hogger system after trips from power when the plant was being held at hot shutdown and would again be escalated back to normal operation.
The leaves were picked to determine if an iodine release occurred, but the activity observed was cesium.
The sample size was 1.24 kgm.

3.7 External Penetratin Radiation A thermoluminescent dosimeter (TLD) with a sensitivity of 5 millirem/quarter is issued 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 g7 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
- 1991, omitting location 7, on-site exposure ranged between 7.3
-17.0 mrem/quarter, with an average exposure of.11.4 mrem/quarter and off-site 7.3 21.3 mrem/quarter with an average exposure of 10.0 mrem/quarter.
Table 3-18 gives TLD
,readings for each quarter.
One TLD was wet at the time of being read and its value is deleted.
The high value at location 34 during the third quarter may be due to poor annealing before being placed in the field.
A trend chart with a comparison of data for each location for the years of 1990 and 1991 is included.
The data plotted is the average quarterly dose measured.
The NRC also obtains TLD measurements around the plant.
following is a
comparison of the data for the first second quarters of 1991 using NRC data from NUREG-0837 10, No. 1, 2, 3, and 4.

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.
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.

5.0 EXTERNAL INFLUENCES During
- 1990, 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 analy'z ing the same samples.
Table 6-1 is a tabulation of the samples analyzed during 1991.

Notes to Table 6-1 Gross Alpha-Beta in Water 1/25/91 Alpha The efficiency used for the weight of solids on the sample overestimated the true activity.
A recalibration showed the efficiency should have been 4 to 6 times larger.
Air Filter Milk 3/29/91 8/30/91 Alpha Beta Cs-137 Cs-137 The alpha and beta were calculated with the ef-ficiency for the wrong geometry.
The reported values should have been for alpha 33, 33, 31 and
, for beta
- 131, 128, 123.
A check of the Ge(Li) detector with a
Cs-137 source and comparison to an NIST intralab check program source indicate the calibration may over-estimate by 74.
This would not be sufficient to bring the value down to the EPA value for the 3/29/91 sample, but would for the 8/30/91 sample.
The calibration for the filter geometry is dif-ficult and normally over-estimates the true acti-vity.
4/2 6/9 1 I-131 Cs-137 K-40 See discussion above on check of calibration.
The same variation appeared to be present in liquid and filter geometries calibra-ted with the sources used for the 1991 calibration.
A 74 change would have brought these values within +
2 sigma.
