RADIOLOGICAL ENVIRONMENTAL SURVEY Janua << December 1985 The environment surrounding the Ginna Nuclear Plant is routinely monitored to determine the influence of plant operation on the levels of man-made radioactivity. Samples are collected. on-site where concentrations would be expected to be highest from the plant should occur and compared to samples which have if a release been collected simultaneously at points where the concentration of the plant effluents 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'uring the year of 1985, 1501 samples were obtained and analyzed.

434 of these samples were analyzed by a gamma scan. In addi.tion, 17 EPA Interlaboratory Comparison Studies samples were analyzed and reported. The samples included air, water, fallout, fi.sh, vegetation, milk and direct radiation. There was no signif icant 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 our analytic procedures. The calculated concentrations would give a dose commitment well'elow the design objectives specified in Appendix I, 10 CPR 50.

ANALYTICALRESULTS The values listed on the following tables include the uncertainties stated as 2 standard deviations (964 confidence level).

PDR

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.

Approximately 1.06 quarts.

Lower Limit of Detectio 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 0.003 pCi/M Gross beta for 400M3 sample.

Water 1.2 pCi/L Gross beta for 1 liter sample.

Milk 0.24 pCi/L Iodine 131 for 4 liter sample.

Fallout 1' pCi/m /day for 0 '92 M collection area.

Gamma:

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

Radiation 10 millirem/month for one month exposure millirem/ quarter for one quarter exposure (film)

. 5 (TLD).

AIR PARTICULATES 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.

There is a ring of -7 sampling stations on the plant site located from 150 to 300 meters from the reactor at. the point of annual average ground level concentration. In addition, the'aximum 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 the on-site and background samples were 0.022 and 0.021 pCi/M for the period of January to December, 1985. Maximum weekly concentrations for each station were less than 0.057 pCi/m The average concentration, of particulate at the site boundary due to plant releases of iodine and particulate would be 4.21 E-6 pCi/M3 or 5.0 E-44 of the average release concentration of 0.842 pCi/m . The survey can not detect such concentrations against the magnitude of the background.

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 IIIA and 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 1984 and 1985 Air Filter data is included.

All counts were within normal variation seen during the past several 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 3.38 and 3.06 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 is included.

Weekly composite samples are taken from the plant circulating water intake and discharge canal. The yearly averages were 2.63 2.91, pCi/liter for the intake and discharge canal respectively. andThese are essentially the same as the upstream and downstream values of 3.38 and 3.06 pCi/liter as they fall within the error band and range of the measurement.

For all batch releases, the average concentration in the discharge canal from the identified activity was 0.67 pCi/liter. The normal 2 sigma variation in the activity calculation of composite samples is 0.99 pCi/liter or one and one-half the average con-centration 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.

After it was pointed out during an NRC audit in September that we did not meet the LLD required by Technical Specifications iodine in water, an analysis for iodine by separation and beta for counting was begun. The four months of data are included as Table VIB.

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'ith 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, 1985. Table VIII lists the values'or fallout samples.

EXTERNAL PENETRATING RADIATION External penetrating radiation is measured by film badges, which are sealed in plastic with the desiccant. The films are located at 12 air particulate sampling stations and one distant location and are changed monthly. One TLD and film location (57) is affected by the contaminated equipment storage location and indicated ) 20 mr/month exposure. The film badge program was discontinued at the end of the third quarter for the plant personnel monitoring and also for the environmental program.

A thermoluminescent dosimeter (TLD) with a sensitivi.ty of 1 millirem is issued as part of the environmental TLD badges are currently placed in four rings around monitoring.'hirty-nine 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.

For the year of 1985, omitting location 7, on-site exposure ranged between 13.5 and 22.0 mrem/quarter, with an average exposure of 17.4 mrem/quarter and off-site 10.3 to 19.4 mrem/

quarter with an average exposure of 15.2 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 1984 and 1985.

M~XL Mi.lk samples are collected monthly duri.ng November to May from one of the three and biweekly during June to October from each of the three dairy herds located three to five miles from the plant. 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 fi.ssion products.

The method i.nvolves chemical separation of iodine and gross beta counting. Interference from other radioactive isotopes has made the results suspect in that they are biased hi.gh. 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 1985( 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 i:n the Offsite Dose Calculation Manual. The maximum resultant annual thyroid dose for 1985 would be 0.029 mrem. The annual average plant release rate would give a concentration of <

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

LAKE ONTARXO 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.

Xsotopic Gamma Concentrations (pCi/wet kilogram) are listed in Table XI.

A sample of the sand was obtained from the lake bottom in the discharge plume area. Results of the gamma scan are included in Table XI.

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 XXB.

EPA NTERLABORATORY 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 XIIX is a tabulation of the samples analyzed during 1985.

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.

The following deviation occurred in the fish progr'am. The Tech Spec Table 3.16-1 gives the number of samples as - 4 control and frequency as - twice during fishing season including at least four species. During 1985, only three different species of fish were collected during each half of the fishing season which were applicable to the program or of sufficient size to qualify as edible. An effort was made to have controls of the same species as those caught in the Ginna discharge plume.

RESULTS NOT MEETING THE MAXIMUM LLD The maximum LLD values as defined by Tech Specs are:

a. LLD for drinking water

b. Total for parent and daughter The following water samples exceeded the maximum LLD for iodine as specified in Tech Specs and are reported here as recpxired.

Sample: Reason Sept. Well Very small chemical yield of 10.54 gave an LLD value of le97 pCi/l.

Sept. Russell Comp. ,Delay in receiving final composite sample caused a large decay correction of 2.63 giving an LLD of 1.71 pCi/l.

Sept. OWD Comp. Delay in doing analysis caused a large decay correction of 2.06 giving an LLD of 1.24 pCi/1'.

Sept. Circ. Zn Comp. Delay in doing analysis caused a large decay correction of 3.16 giving an LLD of 1.62 pCi/1.

Sept. Circ. Out Comp. Delay in doing analysis caused a large decay correction of 2.82 giving an LLD of 1.21 pCi/1.

Nov. Russell Comp. Delay in receiving final composite sample caused a large decay correction of 2.20 giving an LLD of 1.22 pCi/l.

The technicians have been instructed in the need to do iodine analyses as soon as possible after the completion of the sampling period to alleviate the problems of high decay corrections in the calculation of the LLD.

Milk; Farm A Oct. Zodine sample contaminated during separation with Cs-137 from EPA sample. Contamination identified by gamma scan of iodine precipi-tation. No Cs-137 identified in gamma scan of raw milk. Farm resampled for iodine analysis following day with an LLD achieved of 0.33 pCi/l.

During the installation of some inline equipment using the same sample line as the circ. out (discharge canal) automatic sampler on Dec. 3, 198S, the sample line was rerouted to a drain instead of back to the sampler. The situation existed for 13 days before it was was recognized and corrected.

TABLE XIII NOTES:

Gamma in Water 2/8/85 Three isotopes were identified as greater than the EPA value

+2 sigma. The Cr-51 and Ru-106 known values were less than the LLD for the equipment. The isotopic identification program

~

located poorly defined peaks and determined values which were reported. The sample was counted in a container contami-nated by earlier EPA gamma in water s amp 1 es and the known background contamination of Cs-137 was not subtracted before reporting the value in the report. The bkgd of the container is ll pCi which would have reduced the reported values to 26, 27 and 29 compared to the known EPA value of 25.

Gamma in Water 6/7/85 Cr-51 was identified as greater than the EPA value +2 sigma and Ru-106 was identified as less than the EPA value -2 sigma.

For both isotopes, the isotopic identification program located poorly def ined peaks and determined values which were reported. The known Cr-51 value was less than the LLD for the equipment.

Gamma in Water 10/4/85 Ru-106 was identified as greater than the EPA value +2 sigma. The known value was less than the LLD for the equipment. The isotopic identification program found a peak within + 2 Kev of the energy of the Ru-106 and calculated a value which was reported.

Tritium in Hater 2/2/85 Tritium was identified as and 6/4/85 greater than the EPA known value +2 sigma. There is no apparent reason for the dif-ference. The change of 1 cpm in the count rate would have resulted in a sample value with less than 1 sigma difference.

Low Level Zodine 2/29/85 The iodine 131 value reported in Milk was greater than the EPA value

+2 sigma. The low level beta counter was not operable at the time of the sample and it counted on a counter with a was higher background. A variation in the background or gross count of 0.3 cpm would be equal to the 2 sigma difference.

Normal background variation can easily be 0.3 cpm for the counting equipment.
