Dear Mr. Haynes:

tne period frcm January I'uring 1 to June 30, 1982, 9753 cubic feet of solid waste containing 151.5 curies of mixed'ission products was shipped off site. 74$ by volune was shipped to Hanford, Nashington, the remainder to Barnwell, South Carolina.

During this perioa of time, m experienced a stean generator tuoe rupture. Released during this incident was 30 curies of noble gases, 0.2 curies of equiv. I-131, 0.4 curies of particulates and 5 curies of tritiuu. Ihese releases were not reported uncier the normal Tech Spec releases and are not tabulated in the attached monthly release summaries. A detailed sunmary of the releases was submitted in section 7 of the "Incident Evaluation, Q~Gi:nna-stean Generator tute Failure Incident, Jan. 25, 1982, R.E. Ginna Nuclear Fomr plant,

'=Cocket iM. 50-244".

During the remainder of the reporting period, we released through noanal discharges 190e6 curies of tritiun, 0.4 curies of mixed fission products in our liquid releases ana tnrough our gaseous releases; 946.7 curies of noble gases, 2.7 E-3 curies of halogens, 1.88 E-4 curies of mixed fission products and 32.2 curies of tritiun.

Also included are tm corrections to previous submittals.

'the~1981 environmental moni'tormen report which is normally included in the semi-annual effluent report was ani;tted frcm the-July through December L1981 report. Also in that docunent an error was made on the report of man rem by sark am job function. Both the original and the corrected docunent are inclu3ed. 'Ihe error was made in the colunn headings.

RADIOLOGICAL ENVIRONMBlTAL SURVEY Jan December 1981 SUiiRY The environment surroundirg the Ginna Nuclear Plant is routinely monitored to determine the influence af plant operation on the levels af man-made radioactiv-ity. Samples are collected on-site where concentrations would be expected to be highest if a release frcm the plant should occur and compared to samples which have been collected simultaneously at points where the eoneentration af the plant effluents is calculated to be less than 1$ of those at the closer locations. The reference samples provide a run~ background which makes it possible to distin-guish between significant radioactivLty introduced to the environment from the operation a". the plant arxl that introduc& by nuclear detonations or otner sources.

The samole and analysis requirements, as specified in the Technical Specifica-tions, are governed by the fraction af the annual allowable release rate at which the plant, is operating. For the year of 1981, the mLniaam program was required (Regime 1) since actual releases were less than 1/30th of the annual allowable release. However, tne actual program that was conducted was approximately that anticipated with the proposed Environmental Tech. Specs. for Ginna Station.

During the year of 1981, 1457 samples were obtained ant analyzed, 380 af these samples were analyzed by a @mrna, scan. In add'tion, we received 48 EPA Interlabo-ratory Comparison Studies samples which were analyzed ard reported. The samples included air, water, fallout, fish, vegetation, milk and direct rad1ation.fluctua-There "

was no significant difference between on-sita ard off-site samples and no positive results were found that were due to plant operations. We concentrations of radioactiv material in the enviroment resulting frcm plant releases were calcu-latea from the m asured release rates and dilution factors. 'Ihese calculated concentrations could not have been detected because of th magnitud ard tionss of'he background or because they were below the sensitivity af our analytic procedures. The calculated concentration would give a dose ccamLtm nt well-below the design objectives specified in Appendix I, 10 CFR50.

ANALYTICALRESULTS The values listed on the following tables include the uncer~ties stated as 2 standard deviations (96$ conf1dence level).

Ke Definitions Curie (Ci): 'le quantity of any radionuc11.de in which the number of disintegrations per second is 37 billion.

P'cocurie (pC1): One millionth af a mLLlionth af a curie or 0.037 dis-integrations per second.

Ke Definitions (Con't)

Cubic Meter (N3): Approximately 35.3 cublc feet.

Liter (L): Approxinetely 1.05 quarts.

Lower Lindt of Detection

%he Nuclear Regulatory Camdssian has requested that reported values be canpared to the Lower Limit af Detection (LLD) for each piece of equipment. Table XZZ ls a, listing af the LLD values for @anna, lsotopes usia; our Ge(Li) multichannel pulse height detector system. these values are before the correction for decay. An explanation af the calcu'~ tlcn of the LLD ls included following Table XII. Grass detection Led.ts are as follows:

Beta:

0.002 pCl/M3 Gross beta for 400M3 sample.

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

Milk 0.05 pCi/L Iodine 131 for 4 liter sample.

Fallout 0.5 pCl/N2/~- for 0.092 N2 collection area.

Ganma:

0.03 pCl/m3 Iodine 131 on charcoal cartridge for 400M3 sample Radiation 10 mlllirem/month for one month exposure (fi3m).

1 ~~rem/quarter for one quarter exposure (KZ)).

AIR PAFZECULA~

PMioactlve particles in air are collected by dra~ approximately one cfm through a two inch diameter particulate filter. 'Ihe volume af air sampled is measured by a dry gas meter ard corrected for the pressure drop across the filter.

The filters are changed weekly and allowed to decay for three days prior to count-ing to eUminate most af the natural radioactivity such as the short half-life daughter products af radon and thoran. %he decay period is used to gee a rove sensitive. measurement af long-lived man-made radioactivity.

There is a ring of 7 sampling stations on the plant slte located approximately 1000 feet from the reactor at the point af the naxlmum annual average ground level concentratlon. In addition, there is a ring of 5 sampllxg stations located approximately 10 mlles from the site that serve as background statlons.

Based on weekly comparlsons, there was no statistical difference between the on-slte and the background radioactive particulate concentrations. 'ihe average con-centrations for the on-site and background samples was 0.120 and 0.120 pCl/M3 for the period af January to December 1981. ~&num weekly concentratlons for each station were less than 0.21 pCl/N ~

The average concentration of particulate at the site boundry due to plant releases of iodine and particulate would be 1.78 E-4 pCi/N3 or 1/6,300 the average release concentration of 1.16 pCi/m3. 'Ihe survey can not d tect such concentrations against the magnitude of the background.

During the first 7 months of 1981, the air particulate activities were higher than expected because of the continuing influence of the October 17, 1980 A-bomb test detonation by @dern.

Table IA is a list of values for the on-site samplers during January to June, Table IIA is a list for the off-site locations during January to June. Table IB is a list of values for the on-site samplers during July to December, Table IIB is a list for the off-site locations during July to December.

The particulate filters frcm each sampling location were saved ard a 13 week composite was made. A genxna. isotopic analysis was done for each sampling location and corrected for decay. T'esults of this analysis are listed in Tables IIIA, B, C, and D.

DxUza cartridges are placed at four locations. These cartridges are changed and counted each week. A list of values for these cartridges is gLven M Table IV.

WATER Composite samples are collected weekly from Lake Ontario, upstream (Russell Sta-tion) and downstream (Ontario Water Plant) and analyzed for gross beta activit;y.

There was no significant difference between the upstream and downstream sample concentrations. 9he yearly averages were 3.76 and 3.27 pCi/liter for the upstream and downstream samples respectively. Results are listed in Table V for January to December..

Weekly composite samples are taken frcm the plant circulating water intake and and discharge ~,

discharge canal. 'Ihe yearly averages weve 3.54 and 3.51 pCi/liter for the intake respectively. Results ave listed in Table V.

Releases of gross betagymm. activity frcm the plant to the discharge canal gave an average concentration cf <0.001 pCi/liter M tne canal. 'Ihe survey cannot detect this concentratim du to th rr~tude ard th fluctuation o." the back-ground lake water activity. Tne concentration at the Ont;avio Mater Plant would be only 1/20th of the discharge canal concentrations ov <0.0005 pCi/liter due to plant releases.

Samples of tap water, the nearest well, and the creek which crosses the site were collected and analyzed monthly. '3he results show no Mdication cf plant influ-ence. These results are listed in Table VE.

Ganxra isotopic analysis was done on some of the water samples. These are listed in Table VII.

Fallout is a term used to denote radioactive material sett'.rg fran the atmosphere to the ground. At the sampling stations, the fallout settles as dust or is col-lected with rainfall by a funnel ard 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 fran the upper to the lower atmosphere M congunc-0ion with increased rainfall. Lhere was no significant difference between on-site ard off-site samples for the period of January to December, 1981. Table VIII lists the values for fallout samples.

ECKRNAL PEblEZRATENG RADIATION External penetrating radiation is measured by fi3m badges, wnich are sealed in plastic with the desiccant. 'Ihe films are located at 12 air particulate sampling stations and are changed monthly. Readings for all fi3ms, both on-site ard off-site, were 3ess than the rrdn1nMm sensitivity of 10 millirem per ninth.

A thermoluminescent dosimeter (TU)) system with a sensitivity of 1 milliran is used as part of the environmental mnitoring. '3hirty-nine TLD badges are cur-rently placed <<m four rings around the plant. These rings range fran less than 1000 feet to 15 miles and have been dLspersed so as to give indications M each of the nine lard based sectors arourd the plant potential population exposures should an excessive release occur from the plant. Each badge contains 3 CaS04:Dy discs M a teflon matrix and are shielded by a copper filter to correct for overresponse to low energy photons. Badges are changed and read after approximately 3 months exposure.

For the year of 1981, on-site exposure ranged between 0.85 and 1.59 mrem/wk, with an average exposure cf 1.17 mrem/wk and off-site 0.78 to 1.52 mrem/wk with an average exposure of 1.06 mrem/wk. Tables 3ZA and IXB give TU3 readings for each quarter.

Milk samples are collected monthly fran one af the three closest dairy herds located three to five m11es from the plant. 'Ihe milk is analyzed for Iodine-131.

The method involves chemical separation of iodine ard gross beta counting.

Interference from other radioactive isotopes has nade the results suspect M 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 d termine th half-life of the activity in the sample is difficult because of the low countirg rates in-volved.

T¹ average Iodine-131 concentration

<0.09 pCi/liter.

in ~~ for t¹ twelve month period was Th annual dose to th thyroid of an infant which could result fran .he measured plant release rate, was calculated by the method cescribed in the USNRC Regula-tory Guide 1.109. %he resultant annual thyroid dose for 1981 would be 0.030 mrem. The annual average plant release rate would gi.ve 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, ard counted for gannna emitting isotopes. Gross gama activity was normal and no isotopes attributed to plant operations were detected.

Isotopic Ganrna Concentrations (pCl/wet kilogram) are listed in Table XI.

A sample of the sand was obtained fran the lake bottan in the discharge plume area. Results of the gunna scan are &eluded on Table XI.

Additional samples representing vegetation and fruit were taken ard analyzed for ganrna enitting isotopes. The results for these samples are listed in Table XZ3.

EPA Interlaborator Can lson Stud An indication af the plants ability to analyze samples ard achieve results consis-tent with other laboratories ls the aim af the EPA Interlaboratory Ccmparlson.

Selected unknowns are received and analyzed by our procedures ard the results are sent to the EPA Ehvlrornnental Monitoring Systems Laboratory. A report is returned frcm than indicating the concentrations with which the samples were spiked and how we con@ared to other 3aboratories do~ the same samples.

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

4.66 Sb E ' '.22 o Y 'xp [(-<t)) ]

where LLD is the lower 1fmit of detection as d fined above (as pCi per unit nass or volume)

Sb is the standard deviation of the backgrourd country rate or of the counting rate of a blank sample as appropriate (as counts per ndxrute).

E is the countirg efficiency (as counts per disintegration)

V is the sample sMe (in units of mass or volte) 2.22 is the number of disintegrations per minute per picocurLe Y is the fractional radiochemical yield (when applicable) his the radioactive decay constant for the particular radionuclide Dt is the elapsed time between sample collection ard country The value of Sb used in the calculation of the LLD for a particular measurement system shall be based on the actual observed variance af the background counting rate or of the count~ rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gmxna-ray spectranetry, the backgrourd shall include the typical contributions of other radionuclides normaDy present M the samples (e.g., potassium-40 M milk samples).
