RADIOLOGICAL ENVIRONMENTAL'URVEY-Zanua

- December 1988 The environment surrounding the Ginna Nuclear Plant is routinely monitored to determine the influence of plant operation on the levels of'an-made radioactivity.

Samples are collected on-site where concentrations would be expected to be highest if a release from the plant should occur and compared to samples which have been collected simultaneously at points where the concentration of the plant effluentp is calculated to be less than 14 of those at the closer locations.

The reference samples provide a running background which makes it possible to distinguish between signifi-cant radioactivity introduced to the environment from the operation of the plant and that introduced by nuclear detonations or other sources.

During the year of 1988, 1787 samples were obtained and analyzed.

437 of these samples were analyzed by a gamma scan.

In addition, 16 EPA'Interlaboratory Comparison Studies samples were analyzed and reported.

The samples.

included

air, water,

fallout, fish, vegetation, milk and direct radiation.

There was no significant difference between on-site and off-site samples and no positive results were found that were due to plant operations.

The concentrations of radioactive material in the environment resulting from plant releases were calculated from the measured release rates and dilution factors.

These calculated concentrations could not have been detected because of the magnitude and fluctua-tions of the background or because they were below the sensitivity of the analytic procedures.

The calculated concentrations would give a dose commitment well below the design objectives specified in Appendix I, 10 CFR 50.

ANALYTICALRESULTS The values listed on the following tables include the uncertainties stated as 2 standard deviations (954 confidence level).

r 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 XII 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 following Table XII.

Gross detection 'limits are as follows:

Beta:

Air Water Milk 0.003 pCi/M Gross beta for 400M sample.

1.2 pCi/L Gross beta for 1 liter sample.

0.24 pCi/L Iodine 131 for 4 liter sample.

Fallout 1.1 pCi/m /day for 0.092 M collection area.

Gamma:

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

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

AIR PARTICULATES Radioactive particles in air are collected by drawing an air sample through a two inch diameter particulate filter at a rate of approximately 1 cfm.

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.

There is a ring of 6 sampling stations on the plant site located from 150 to 300 meters from the reactor at the point calculated to be. indicative of maximum annual average ground level concen-trations for normal plant releases.

In addition, there is a ring of 5 sampling stations located approximately 7 to 10 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 both the on-site and background samples were 0.018 pCi/M for the period of January to

December, 1988.

Maximum weekly concentrations for each station were less than 0.039 pCi/m The average calculated concentration of particulate at the site boundary due to measureable plant particulate releases would be 6.97 E-8 pCi/M or 0.00027% of the average release concentration of 2.58 E-2 pCi/m The environmental sampling program can not detect such concentrations against the magnitude of the background of 0.014 pCi/m Table IA is a list of-values for the on-site samplers during January through June, Table.IIA-is a-list-for the on-site locations during 'July through December.

Table IB is a list of -values for the-off-site samplers during January through June, Table IIB is a list for the'off-site locations during July through December.

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 'this analysis. are listed in Tables IIIAand B.

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 IV.

A trend plot of the 1968 to 1988 Air Filter data is included.

Preoprational data in 1968 and 1969 were approximately an order of magnitude higher than current values due to atmospheric bomb testing during those years.

WATER

" 'Composite samples are collected weekly from Lake Ontario, upstream (Russell Station) and downstream (Ontario Water Plant),

and analyzed for gross beta activity.

There was no significant difference between the upstream and downstream sample concen-trations.

The yearly averages were 2.24 and 2.35 pCi/liter for the upstream and downstream samples respectively.

Results are listed in Table VA for January through June and Table VB for July through December.

A trend plot of the upstream and downstream samples from 1968 to 1988 is included.

Preoperational data in 1968 and 1969 were approximately a factor of 2

higher than current values due to fallout from bomb testing during those years.

Weekly composite samples are taken from the plant circulating water intake and discharge canal.

The yearly averages were 2.19 and 2.07 pCi/liter for the intake and discharge canal respectively.

These are essentially the same as the upstream and downstream values of 2.24 and 2.35 pCi/liter as they fall within the error band of +

2 sigma and range of the measurement.

For all batch releases, the calculated average concentration in the discharge canal'from the identified activity was 0.058 pCi/liter.

The normal'2 sigma variation" in 'the=activity calcula-tion of composite samples is

0. 84 pCi/liter or

15. times the average concentration added by releases from the plant.

Samples of tap water, the nearest well, and the creek which crosses the site were collected and analyzed monthly.

The results show.no indication of plant influence.

These results are listed in Tables VA and VB.

Gamma isotopic analysis was done on each monthly sample and biweekly or monthly composites of weekly samples.

These are listed in Table VII and separated by source of sample.

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.

There was no significant difference between on-site and off-site samples for the period of January through

December, 1988.

Table VIII lists the values for fallout samples.

EXTERNAL PENETRATING RADIATION A thermoluminescent dosimeter (TLD) with a sensitivity of 1

millirem is issued as.part of.,the environmental monitoring.

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 so as to give indications in each of the nine land based sectors around the plant potential population exposures should an excessive release occur from the plant.

Badges are changed and read after approximately 3 months exposure.

TLD location 47 is influenced by its close proximity to the Contaminated Equipment Storage Area established in 1983 and will normally read 40-60 mRem/quarter.

For the year of 1988, omitting location 7, on-site exposure ranged between 11.0 and 18.3 mrem/

quarter, with an average exposure of 14.2 mrem/quarter and off-site 10.0 to 18.5 mrem/quarter with an average exposure of 12.9 mrem/quarter.

Table IX gives TLD readings for each quarter.

A trend plot of the quarterly average dose rate by TLD location is included comparing 1987 and 1988.

During early

1987, adjustments were made to the TLD system which

- may have resulted in increased accuracy for low dose measurements.

"'This may explain the apparent difference<between the 1987,.and 1988 average environmental exposures.

~ Environmental factors could also have caused this difference.

The NRC also does TLD measurements around the plant.

During the period starting in June through

October, a

sample is collected from each farm biweekly (once every two weeks).

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.

Interference from other radioactive isotopes has made the results suspect in that they are biased high.

The counting procedure is not specific for Iodine-131 and other isotopes may add to the count rate.

Attempts to determine the half-life of the activity in the sample is difficult because of the low counting rates involved.

During 1988, no samples indicated positive activity that exceeded the LLD for the analysis.

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.

The maximum resultant annual thyroid dose for 1988 would be 0.007 mrem using the cow-milk-infant pathway.

The annual average plant release rate during the grazing season would give a concentration =of

< 0.005 pCi/liter of Iodine-131 in milk, which is below the LLD for this analysis.

LAKE ONTARIO FISH Fish caught near the discharge canal outfall were filleted, and counted for gamma emitting isotopes.

A comparison to data for fish caught 15 miles and more away from the plant shows no indication of plant influence since neither cobalt-60 or cesium-134 were detected.

Some samples of both indicator and background fish had detectable amounts of cesium-137.

Isotopic Gamma Concentrations

- (pCi/wet

- kilogram), are.. listed.'in Table XI.

A sample of algae (cladophora) and of the sand was obtained from the lake bottom in the discharge plume area.

Results of the gamma scans are included in Table XI.

Cesium-137 was detected in lake bottom

sample, but the absence of cesium-134 and cobalt-60 indicates the cesium-137 is probably due-to fallout.

The lake bottom is mainly rock with very infrequent small quantities of sand.

This makes lake bottom sampling extremely difficult.

OTHER SAMPLES Additional samples representing vegetation and fruit were taken and analyzed for gamma emitting isotopes.

The results for these samples are listed in Table XIB.

LAND USE CENSUS A land use census was done to determine changes in the use of the land within 5 miles of the plant.

There were no major changes in the use of the land with most remaining agricultural.

There were several private homes constructed, but no new housing developments or large business construction projects.

The three dairy operations continued with an average of 40 to 70 milking cows.

There were no goats used for milk on a regular basis within the 5

mile radius.

There was an increase in cattle raised for beef.

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 XIII is a tabulation of the samples analyzed during 1988.

DEVIATIONS TO THE SAMPLING PROGRAM Deviations to the sampling program are permitted when samples are not obtainable due to hazardous conditions, seasonal availability or to malfunctioning of automatic sampling equipment.

Samples that were not available due to malfunctioning of automatic sampling or not available for a specific reason are noted on data table pages.

TABLE XIII NOTES:

Gamma in Water Iodine-131 in Water Iodine-131 in Milk 6/03/88 8/05/88 2/26/88 Cs-134 and Cs-137 were greater than

+2 sigma from the known value.

A plastic counting marinelli used for previous EPA samples was used and no back-ground for contamination was subtracted.

After subtraction of background contamination the results would still be high but within +2 sigma.

No apparent reason why the gamma scan for I-131 showed a result greater than

+2 sigma.

A recheck of the calibration showed no appreciable change in the efficiency for the I-131

'" peak energy or"area as determined by the computer program.

The replication of results was poor with one value equalling the known and two being low.

No specific cause could be determined.

Tritium in Water 6/10/88 10/14/88 The low counting rates mean a

small variation in background can change the calculation by large percentages.

The wrong background value may have been used for the calculation causing the calculated value to be either low or high.
