l SUf1 MARY AND CONCLUSIONS

I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Limerick Generating Station by Philadelphia Electric Company covers the period 1 January 1986 through 31 December 1986. During that time period, 3009 analyses were performed on 2406 samples.

l As a result of the nuclear accident at Chernobyl on April 26, 1

1986, radioactive f allout was deposited throughout the world including the Limerick Area. The results of the data from samples collected af ter the accident are discussed in Appendix 0 of this report.

Surface and drinking (potable) water samples were analyzed for concentrations of gross beta (soluble and insoluble fractions), tritium, and gamma emitting nuclides. Concentrations detected were consistent with those observed in other years.

Fish (predator and bottom f eeder) and sediment samples were analyzed for concentrations of gamma emitting nuclides and the concentrations detected were consistent with those in other years.

Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Concentrations detected were consistent with those observed in other years.

High sensitivity I-131 analyses were performed on weekly air samples. All results were less than the minimum detectable level.

Cow and goat milk samples were analyzed for concentrations of I-131 and gamma emitting nuclides. Concentrations detected were consistent with those observed in other years.

Well water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Concentrations detected were consistent with those observed in other years.

Vegetation samples were analyzed for concentrations of gamma emitting nuclides. Concentrations detteted were consistent with those observed in other years.

A game sample was analyzed for conce.itrations of gamma emitting nuclides and concentrations detected were consistent with those observed in other years.

Environmental gamma radiation measuromonts were made monthly and quarterly using thermoluminescent dosimeters. Levels detected were consistent with those observed in other years.

1 INTRODUCTION

LIMERICK OENERATING STATION Radiological Environmental Monitoring Program II. Introduction The Limerick Generating Station (LOS), consisting of two 1055 MWe bolling water reactors owned and operated by Philadelphia Electric Company (P Eco ), is located adjacent to the Schuylkill River in Montgomery County, Pennsylvania. Unit No. I went critical on 22 December 1984 and Unit No. 2 is under construction. The site is located in Piedmont countryside, transversed by numerous valleys containing small tributarles which f eed into the Schuylkill River. On the eastern river bank elevation rises from approximately 110 to 300 feet mean sea level (MSL). On the western river bank elevation rises approximately 50 feet MSL to the western site boundary.

A Radiological Environmental Monitoring Program (REMP) for LOS was initiated in 1971. Review of the 1971 through 1977 REMP data resulted in the modification of the program to comply with changes in the Environmental Report Operating License Stage -

(EROL)( 8 3 and the current revision of the Branch Technical Position Paper.(23 The preoperational period for most media ,

covers the periods 1 January 1982 through 21 December 1954 and was summarized in a separate report.(33 This report covers those analyses performed by Telodyne Isotopes (TI) on samples collected during the period 1 January 1956 through 31 December 1986.

A. Objectives The objectives of the Radiological Environmental Monitoring Program are:

1. To provide data on measurable levels of radiation and radioactive materials in the site environs.

2. To evaluate the relationship between quantitles of radioactive material released f rom the plant and resultant radiation doses to individuals from principal pathways of exposure.

B. Implementation Imptomentation of the stated objectives is accomplished by identifying significant exposure pathways, establishing baseline radiological data of media within those pathways, and continuously monitoring those media before and during Station operation to assess Station effects (if any) on man and the environment.

In order to achieve the stated objectives, the current program includes the following analyses on samples collected:

1. Concentrations of tritium in surface water, drinking (potable) water, and well water.

2. Concentrations of beta emitters in surface water, drinking (potable) water, and air particulates.

3. Concentrations of gamma emitters in surface, drinking (potable), and well water, air particulates, milk, vegetation, game, fish, and sediment.

4. Concentrations of I-131 in air and milk.

5. Ambient gamma radiation levels at various site environs.

PROGRAM DESCRIPTION

III. Program Description A. Sample Collection Samples for the LGS REMP were collected for Philadelphia Electric Company by Canberra /RMC. Thi s section describes the collection methods used by Canberra /RMC to obtain environmental samples for the LGS REMP in 1986.

Aountic Environment The aquatic environment was examined by analyzing samples of surf ace water, drinking water, fish, and sediment. Two gallon water samples were collected monthly f rom continuous samplers located at six surface water locations (10F2, 15F5, 16B2, 24S1, 24S2, and 13H5 (after 8/29/87)) and four drinking water locations (15F4, 15F7, 16C2, and 28F3).

One additional drinking water location (13H2) was sampled monthly by compositing weekly grab samples until 8/29/86 when a composite sampler was installed.

Control locations were 10F2, 2451, 24S2, and 28F3. All containers used were new unused plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprising the flesh of two groups, catfish / bullhead (bottom f eeder) and sunfish (predator), were collected semi annually at three locations: 16C5 and 20S1 (Indicator) and 29C1 (control). Sediment samples composed of recently deposited substrate were collected at three locations semi annually: 16B2 and 16C4, (Indicator) and 33A2 (control).

Ainoscheric Environnent The atmospheric environment was examined by analyzing samples of air particulate, airborno lodine, milk, well water, food products and game. Air particulate and airborno lodine samples were collected weekly at seventeen locations (281, 6C1, 9C1, 1053, 1151, 13C1, 13H4, 1451, 15DI, 1781, 20D1, 2201, 26B1, 2981, SIDI, 34S2, and 3581). Of the airborne lodine samples at those seventeen locations, eight (1053, 1151, 13C1, 13H4, 1451, 2201, 31D1, and 3581) were analyzed for I-131. The remaining nine samples were collected and etalnad for analysis if necessary.

Control locations were 13H4 and 2201. Air particulate and airborne lodine samples were obtained using a vacuum sampler, glass fiber and charcoal filters, respectively. The filters were replaced weekly and sont to the laboratory for analysis. The vacuum samplers were run continuously at approximately 1 cubic foot per minute.

l I

Milk samples were collected bi weekly at four locations (5C1, 1081, 22F1, and 25B1) and monthly at eight locations (36Et, 9Et, 901, 11D1, 11El, 17C2, 18C1, and 21B1) during April through November, and monthly at all locations during December through March. Locations 901 and 22F1 were controls. Two of the sample stations 11D1 and 11El went out of business during the reporting period. Station 11D1 was replaced by 15E2 but it was decided not to replace 11E1. Samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, refrigerated, and shipped promptly to the laboratory. Ho preservative was added.

Well water samples were collected semi annually from two locations 1151 (indicator) and 18A1 (control) in new unused two gallon plastic bottles. Vogetation samples composed of broad leafy vegetation and root crops were collected monthly f rom one location (11S1) during the growing season (May through September). A game sample was collected annually from one location (26S5) by hunt ing.

Ambient Gamma Radiation Direct radiation measurements were made using thermoluminescent dosimeters (TLD) consisting of calcium sulf ato (CaSO4) doped with dysprosium (Dy). The TLD locations were placed on and around the LOS site using a "three ring concept" consisting of:

A site boundary ring consisting of sixteen locations (36S1, 3S1, 5S1, 751, 1053, 1151, 14S1, 16S2, 18S1, 21S1, 23S2, 25S1, 26S3, 2951, 32S1 and 34S2) near and within the site perimeter representing fencepost doses (i.e., at locations where the donos will be potentially greater than maximum annual off-site doses) from LOS releases:

A middle ring consisting of twenty seven locations (2B1, 2Et, 4Et, 6Cl, 7E1, 9C1, 10El, 10F3. 13Cl, 13E1, 15D1, 16F1, 1781,19DI, 20D1, 20F1, 24D1, 25DI, 26B1, 28D2, 2981, 29Et , 31D1, 31D2, 34Et , 3581 and 35Fl) extending to approximately 5 miles f rom the site designed to measure possible exposures to close-in populations And an outer ring consisting of five locations (5H1, 13H3, 1801, 2201 and 3201) extending from approximately 12 to 30 miles f rom the site and considered to be unaffected by LOS releases.

The specific TLD locations were determined by the following criteria 6-

e l

1. The presence of relatively dense populations

2. Site meteorological data taking into account distance and elevation for each of the 16-22 I 1/2 degree sectors around the site, where estimated annual dose from LOS, if any, would be most significant

3. On hills free from local obstructions and within sight of the vents (where practical);

4. And near the closest dwelling to the vents in the prevalling downwind direction. -

Two TLD sets - each comprised of four thermoluminescent phosphors sealed in plastic to maintain integrity - were placed at nach location in a PVC conduit located approximately three f eet above ground level. The TLD sets were exchanged monthly and quarterly and sent to the laboratory i

for analysis.

B. Data Interpretation The radioanalytical and direct.' radiation data collected prior to LGS becoming operational was used as a baseline with which this operational Cata will be compared. For the purpose of this report, LOS was considered operational at initial criticality. In addition data will be compared ti previous years' operational datn for consistency an'd trending. Several f actors are important in the interpretation of the I

data. These f actors are discussed here to avoid undue repetition in the discussion of the results.

The minimum detectable level (MDL) was defined as the two sigma counting statistic. It represents the range of values into which 95% of repeated counts of the same aliquot would fall. For all analyses (gross beta, I-131, H-3 and gamma) an activity that was greater than or equal to the MDL was reported as " activity plus/minus the two sigma counting statistic". When an activity was less than the MDL, the result was reported as < the MDL value.

The lower limit of detection (LLD) was defined as the smallest concentration of radioactive material in a sample that would yleid a not count (above background) that would be si etected with only a 5% probability of I

f alsely conclucUng that a blank observation represents a "real" signal. The LLD was intended as a before the I fact estimate of a system (including instrumentation.

j e

i Data received *1com the laboratory were reported using I

the convention of rounding the result to the same number of significant places as the first sF&nificant digli in the error term (i.e. 3.62 1 1.23 rounds to 411). Results for each type of sample were grouped l according to the analyses performed. For gamma analyses, . at least those nuclides specified in

'/ ', Technical Specification tabit\ 3.12.1-2 for each sample i ci media and nuclides which had a positive occurence are 6 report ed. Means and standard deviations of these results were calculated. These standard deviations represent the variability of measured results for dif f erent samples rather than single analysis ' 'i 1 uncertainty. For these calculations, all results below the MDL were considered to be at the MDL. As a result, the means were biased high, and the standard deviations d

were generally biased low. ,

! i C. Program Exceptions For 1986 the LGS REMP had a sample collection recovery rate greater than 99.8%. The exceptions to this  ;

program are listed below: ,

1. The surface water sample collected from station 16B2 in February was a grab sample due to a pump malfunction.

2. An air particulate sample was not collected from station 281 betwesa 08/25/86 and 09/01/86 due to e<

pump malfunction, i

3. Air particulate and air lodine samples were not collected from station 3581 between 88/25/86.and 09/01/86 due to a pump malfunction. g  ; ,

1. Surface Water i

i Samples were taken f rom six locations on a monthly schedule. Samples were collected from a continuous sampler at.all six locations (18F2, 15F5, 1652, 2451, 13H5 and 2452). Of these locations, three (15F5, 1682 and 13H5) could be affected by Station di scharges. The following analyses were performed.

Gross Beta Samples f rom all locations were analyzed for concentrations of gross beta in the soluble and insoluble fractions (Tables C-I and C-II, Appendix C). Detectable activity was observed in the soluble and insoluble fraction of the surf ace water ,.

samples. With the exception of the samples which -

show the ef f ects of Chernobyl (Appendix G), the values were consistant with previous years (Figures C-1 and C-2, Appendix C) and ranged f rom 1.3 to 9 pC1/1 for the soluble fraction and from <.3 to 10 pCl/l for the insoluble fraction. No dif ference in activity levels was observed between indicator and control locations for the soluble f raction. The December sample of the insoluable f raction of downstream location 13H5 showed a'significantly higher activity (10 pCl/1) t han the control locations. This higher activity is attributed to the elevated sediment co'ntent of the sample. In addition the gamma analysis indicated elevated levels of naturally occurring K-40 consistent with the gross beta results, i

Tritium Samples from locations 10F2, 1682, and 24S1 were analyzed for aqueous tritium activity (Table C-III, Appendix C). Positive tritium activity was observed at each sample location and values ranged i f rom (40 to 170 pC1/1. No difference was observed between indicator and control station. The values  ;

were consistent with previous years, and all results were below the required sensitivity for t hi s analysis, i

Gamma Snectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-IV, Appendix C). With the exception of naturally occurring K-40, all nuclides searched for were below the minimum detectable level.

2. Drinkina (Potable) Water Monthly samples were taken from five locations. A manually composited sample was collected from location 13H2 until 8/29/86 when a continuous water sample was installed. Samples from locations 15F4, 15F7, 16C2 and 28F3 were collected f rom a continuous water sampler. Four stations ($3H2, 15F4, 15F7 and 16C2) could be affected by Station discharges. The following analyses were performed:

Gross Beta Samples from all stations were analyzed for concentrations of gross beta in the soluble and insoluble fractions (Tables C-V and C-VI, Appendix C). With the exception of the samples which show the ef f ects of Chernobyl (Appendix Gb concentrations detected in both fractions were consistent with those observed in previous years (Figures C-3 and C-4, Appendix C). The values ranged from 1 to 9 pCl/l for the soluble fraction end f rom <.3 to 3.9 pCl/l for the insoluble fraction.

The insoluble fraction of control station 28F3 during March showed elevated activity (3.9 pCl/1).

The gamma analysis on this sample did not identify any gamma emitting nuclides above the minimum detectable level. A duplicate sample of this location yielded comparable results (2.3 pCl/1)_and therefore, this activity is attributed to an unidentified upstream source.

l The concentration of gross beta (soluble) at indicator station 13H2 for April showed higher activity (9 pci/1) than the control location 28F3

, (3 pcl/1). The results were consistent with those observed during the preoperational period (Reference 3). Additionally, the gamma analysis did not identify any gamma emitting nuclides above l the MDL; therefore, the activity at location 13H2 l was attributed to other unidentified sources.

Tritium l Samples from locations 15F4, 15F7, 16C2 and 28F3 were analyzed for aqueous tritium activity (Table C-VII, Appendix C). Positive tritium activity was observed at each sample location. The measurements ranged f rom <50 to 180 pCl/1. No significant difference in tritium activity was observed between ,

the control and indicator locations.

l G- - Snect romet rv Samples from all locations were analyzed for gamma emitting nuclides (Table C-VIII, Appendix C). With the exception of naturally occurring K-40 and Th-228, all nuclides searched for were below the t

minimum detectable level.

3. Elib Fish samples comprised of catfish / bullhead (bottom feeder) and redbreast /pumpkinseed (predator) were collected at three locations (16C5, 20S1 and 29C1) semi annually. Two locations (16C5 and 2051) could be affected by station discharges. The following analysis was performed Ganma Snectrometry The edible portion of fish samples f rom all three locations was analyzed for gamma emitting nuclides (Table C-IX, Appendix C). With the exception of Cs-137 and naturally occurring K-40, all nuclides searched for were below the minimum detectable level. The second semi annual sample f rom stations 16C5 (Indicator) and 29C1 (control) showed trace quantities of Cs-137 (.016 pCi/ gram (wet) and .017 pCl/ gram (wet) respectively). These levels are consistent with those seen during the preoperational period of the program (ref erence 3) and are attributable to previous weapons testing fallout or the fallout from Chernobyl.

4. Sediment Aquatic sediment samples were collected at three locations (1652, 16C4 and 35A2) semi annually. Of these locations, two (16B2 and 16C4) could be affected by Station discharge. The following analysis was performed 13 -

G- e Snectrometrv Sediment samples from all three locations were analyzed for gamma emitting nuclides (Table C-X, Appendix C). Nuclides detected were Be-7, K-40, Mn54, Cs-137, Ra-226, and Th-228. The nuclides The 228, Ra-226, and Cs-137 commonly occur in sediment from daughter decay of natural uranium, or from world wide f allout. Concentrations of Be-7 were the result of cosmic ray activity and K-40 is a naturally occuring nuclide. In addition, concentrations of these nuclides were consistent with those detected during the preoperational REMP.

The concentration of Mn-54 identified in the 10/31/86 sample from station 16C4 was at an extremely low level of .020 pCl/ gram (dry).

Although this is the first time this nuclide has been detected in a sediment sample, it should be noted that this level is below the MDL of this analysis during the preoperational period (Reference 3).

B. Atmospheric Environment

1. A i rbo rn e

a. Air Particulates Continuous air particulate samples were collected from seventeen locations on a weekly basis. The seventeen locations are separated into three groups: Group I represents locations within the LGS site boundary (1053,1151, 14St and 34S2), Group II represents locations near the LOS site (281, 6C1, 9C1, 13C1, 15D1. 1781, 20D1, 26B1, 29B1, 31DI, 35B1), .and Group III represents control locations at remote distances f rom LGS (13H4 and 22G1). The following analyses were performed:

Gross Beta Weekly samples were analyzed for concentrations

, of beta emitters (Table C-XI, Appendix C).

Detectable gross beta activity was observed at all locations. With the exception of the samples which show the ef fects of Chernobyl (Appendix G), concentrations detected were consistent with those observed in previous years (Figure C-5, Appendix C). The values 14 -

l ranged f rom .005 to .040 pC1/m3 No significant dif ference in activity was observed l between the control and indicator stations.

l Gamma Spect romet ry Weekly samples were composited and analyzed monthly for gamma-emitting nuclides (Table C-XII, Appendix C). Naturally occurring Be-7 due to cosmetic ray activity was detected in most samples. These values ranged f rom <.04 to .26 pC1/m3 K-40, also naturally occurring, was detected in fifteen samples. These values ranged from <.001 to .10 pCl/m3 In addition the March composite for station 281 showed a trace amount (0.006 pCl/m3) of naturally-occurring Th-228. With the exception of the samples which show the ef f ects of Chernobyl (Appendix G), all other nuclides searched for were below the minimum detectable level. No significant difference in activity was observed between the control and indicator stations.

b. Airborne Indine Continuous air samples were collected from the same seventeen locations as the air particulate samples. However, of the seventeen locations, eight (10S3, 11S1, 13C1, 13H4, 14S1, 22G1, 31D1, 35B17 were analyzed weekly for I-131.

The remaining nine samples were held and analysis was not necessary. Results of the I-131 analysis are found in Table C-XIII, Appendix C. With the exception of the samples which show the ef fects of Chernobyl (see Appendix G), all results were less than the minimum detectable level.

2. Terrestrial l

a. Dilk l Samples were taken from four locations (5C1, 22F1, 1981, and 2581) bi weekly during the grazing season (April-November) and monthly at other times. Samples from 9 additional locations (2181, 11D1 (until 07/08/86), 17C2, 18C1, 9E1, 11El (until 10/14/86), 36E1, 901, and 13E2 (after 08/04/86)) were taken monthly.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing CaSO4: Dy thermoluminescent dosimeters. Forty eight TLD locations were established around the site in a three ring concept for comparison purposes an " inner ring" of sixteen locations around the site boundary; a

" middle ring" of twenty-seven locations within a ten mile radius of the site; and an " outer ring" of five ,

locations at distances outside the ten mile radius of j the site. Results of TLD measurements are listed in Tables C-XIX to C-XXII, Appendix C. All of the TLD measurements were below 10 mead /std. month, with a range of 4.2 to 9.8 mR/std. month. No significant dif f erences were observed among the results f rom the site, middle, and outer rings (Table C-XII, Appendix C). In addition, levels measured were consistent with those observed in previous years (Figure C-6, Appendix C).

j ENVIRONMENTAL DOSIMETRY TELEDYNE ISOTOPES ' , f l

. l,

Teledyne Isotopes developed a thermoluminescent dosimeter which is a .k rectangular shaped teflon waf er impregnated with 25% CaSO45]y phosphor. ') ,

The dosimeters are annealed in a hot air oven prior to use and are .'

inserted into black polyethylene pouches. The filled pouches are labeled and placed in rectangular holders which contain copper shielding to filter out low energy radiation. Af ter exposure in the environment,5f our a separate areas of the dosimetersare read in a Teledyne Isotopes model 8300 TLD reader. The dosimeter is then re-irradiated by a standardized <

Cs-137 source and the f our areas are read again. Calculation of the ,,!

environmental exposure is perf ormed by computer, using the re-irridiat ion readings to determine the sensitivity of each area of the dosimeter. The ,

transit dose is determined from TLD's located in the lead shield at Teledyne Isotopes Westwood, New Jersey and from TLD's kept in a lead shield in the field. The error is then calculated and subtracted from the gross reading. /[+

Calculation of results:

(a) For any given area of the dosimeter, the dose in mR is calculated by the formula:

DOSE = R REDOSE -

AVCONTROL RR I Where: R  : initial reading of the area i RR = second reading of the area (after re-irradiation) t REDOSE  : re-irradiation dose in mR / ,

i AVCONTROL = average of control values calculated ,

as explained below. If no .

controls are used, AVCONTROL = 0 and gross exposures result, r

f (b) Each area of each ontrol is calculated as follows:  ;'

DETERMINATION OF I-131 IN MILK AND IJATER SAMPLES BY RADI0 CHEMISTRY AND LIQUID PHASE BY ANALYSIS i TELEDYNE ISOTOPES l

This describes the radiochemical methods for determining I-131 activity in milk and water samples by coincidence counting in the liquid phase.

l Four liters of sample are first equilibrated with stable

todido carrier. A batch treatment with anion exchange resin is I used to remove lodido f rom the sample. The lodine is then 1

stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride, and extracted into carbon tetrachloride as f ree lodine. It is then back extracted as lodide into sodium bisulfite solution.

The lodide sample solution is oxidized to the free state using NANO 3 reagent and is extracted several times into a total of 15 ml of toluene. A 200 microllter aliquot is taken for determining chemical yield by spectrophotometer. A decoloriz;ng agent (2 methyl-2-butene) is added to the toluene-lodine solution i to form an inert molecule and to minimize liquid scintillation j quenching. A toluene-based liquid scintillation counting solution is added to the sample, which is then analyzed by a beta gated gamma coincidence counting system.

Calculat ion of the MDL If the not activity (previously defined) is less than a specified multiple of the background counting error, the activity on the i

collection date is below the limits of detection and is called "less than" (L.T.) or " minimum detectable level" (MDL).

The L.T. value can be specified by stating only the counting error at a predetermined multiple (Om) of the one sigma statistics. A sigma multiple (Gm) of 4.66 is used for calculation of the L.T. values unless another multiple such as 2.83 is specified.

DETERMINATION OF GROSS ALPHA AND/OR BETA ACTIVITY IN WATER SAMPLES, AIR PARTICULATE FILTERS, OR SEDIMENT 1

This describes the process used to measure the overall alpha and/or bata radioactivity of water samples, air particulate filters, composite cir particulate filters or sediment without ident i f ying t he radioact ive species present. No chemical separation techniques are involved. One liter of the water sample is evaporated on a hot plate. The sample is rinsed into a 2-inch diameter stainless steel planchet which is i stamped with a concentric ring pattern to distribute residuo evenly.

Final evaporation to dryness takes place under heat lamps. Residue mass is determined by weighing the planchet bef ore and af ter mounting the sample. In the case of air particulate sample, t he filter is mounted

directly on a 2-inch stainless steel planchet. Sediment samples are dried and a 1 gram aliquot is mounted directly on a 2-inch stainless steel planchet .

The planchets are then counted f or alpha /and or beta activity in a Icw background gas flow proportional counter. Calculation of activity includes an empirical self-absorbt ion correct ion curve which allow f or the change in ef f ect ive count ing ef ficiency caused by the residue mass.

Self absorbtion is not considered in the case of air particulate filters bscause of the impracticality of accurately weighing the deposit and i breause the penetrat ion depth of t he deposit into the filter is unknown.

QUALITY CONTROL

l APPENDIX E: QUALITY CONTROL PROGRAM l

TI participates in the EPA radiological interlaboratory comparison (cross check) program. This participation includes a number of analyses on various sample media as found in the Limerick Generating Station REMP. As a result of this l

participation, an objective measurement of analytical precision and accuracy as well as, a bias estimation of the results are obtained. During the time period of this report, 93 of the 95 samples analyzed fell within the EPA mean and standard j deviations. Table E-1 summarizes the results published during the time period of this report.

The second quality control program includes the analysis of blank and spiked samples. Thi s intralaboratory program indicates the proper functioning of the chemistry and instrumentation for gross alpha, gross beta, lodine-131, strontium 59-90, gamma and the tritium analyses. Of the 1073 analyses published during the period of this report, 6 were determined to be outside the expected range. Four of them were inadvertently not spiked and two distilled water samples which were prepared as liquid radweste contained trace amounts of gross beta activity f rom hood contamination. All anomalies were investigated and resolved.

Another quality control program which Teledyne Isotopes participates in conjunction with the Limerick REMP is a duplicate tnalysis program. The duplicate or replicate samples are prepared in the field f rom samples that are as homogenous as possible, such well stirred or mixed liquids or solids. Of the

[ 358 duplicate / replicate samples published in 1986, all were considered to be in agreement with the original result, i

l (e) The three results reported were 43.0, 43.0 and 53.0. The one high result of 53.0 caused the average result i to be above the 2 sigma limit. This sample was aliquoted last of the three samples.and more of the spike may have settled in the bottom of the container.

(f) The efficiencies of the counters were rechecked and some counters recoated to prevent the efficiencies from drifting.

At this activity level the counting error is relatively high.

(h) These air filters are counted for gross alpha, beta and gamma before being analyzed for Sr-90. It'was felt that some of the activity had been lost in handling. The air particulate filters will be handled more carefully in the future. This had not been a problem in previous analyses.

(k) For Sr-90 fourteen of the seventeen laboratories participating were beyond the t 3 sigma level. For Sr-89 thirteen of the fifteen laboratories had low results. It would appear that the sample is flawed in some j way for this analysis, i (1) This analysis was performed by an inexperienced technician who has 6fnce received additional training and is performing satisfactorily.

(m) It is believed that too much NaCo3 was used in the finct precipitation of SrC03 resulting in a falsely high strontium-89 yield. Less NaCO3 will be used in the future precipitation of SrC03 ,

4 1 (n) The data for the samples was examined and no obvious reason for the high result could be found. The'Cs-137 calibration was checked and found to-be in agreement with previous readings. Since this was not a trend in previous analyses for C5-137 in Water (Test 418 -0.023; Test 406 -0.11) it was. decided to follow the  ;

results to see if a trend developed.

Appendix G CHERNOBYL STUDY I. Introduction Radioactive releases f rom the nuclear accident at Chernobyl on April 26, 1986, resulted in increased levels of radioactivity throughout the environment of the United States. The REMP in place at Limerick, by design, is an extremely sensitive Indicator of fluctuations of radioactivity in the environment. In order to provide more rapid information on the potential ef fects of releases from the Chernobyl accident, moderate increases in the frequency of sampling and/or analyses of key media of the program were instituted (i.e. milk, air particulate, surface water, precipitation). As requested in I.E. Information Motice 86-32, results of samples which showed the ef f ects of Chernobyl were phoned into the NRC Operations Center.

II. Samole Collection Additional samples collected in support of the evaluation of the Chernobly accident were collected for Philadelphia Electric Company by Canberra /RMC. With the exception of precipitation samples, all samples collected were from routine sample locations using established and approved sampling procedures. The precipitation samples were obtained by establishing special precipitation samplers at pre-existing sample locations and using common sample practices.

T III. Results and DIncussion A. Aountic Environment

1. Surface Water Surface water grab samples were taken weekly from 1682 (Indicator) and 2451 (control). These samples were analyzed for I-131 activity by coincidence count ing in the liquid phase (Table G-1). The values ranged f rom < 0.04 pCl/l to 0.66 pCl/l which result in comparatively insignificant dose contributions. A s s hown in Figure 0-1, two distinct peaks of activity can be seen. These peaks were consistent with the results f rom other analyses discussed later.

a B. Atmonoheric Environment

1. A i rborna

, a. Air Particulate In addition to the gross beta analyst s performed on each weekly air particulate sample and the monthly compost te gamma analyst s, weekly gamma analyses were performed on stations 3452, 6C1, 15D1, and 31D1.

J Grass.Bata The gross beta results ranged from the normal anticipated value of .005 pCl/cu. noter to .24

pCI/cu. meter (Table G-II). As shown In Figure 0-2, two distinct peaks of acilvity are o bv iou s . The highest peak was approximately l thirteen times higher than the average annual

! valve of approximately .018 pCl/cu. meter (reference 4).

I j Gamma Saectrometrv

'l

In addition to routinely identifled Be-7 and

! K-40, trace concentrations of I-131, Ku-103, Cs-134, and Cs-137 were detected. (Table G-III).

b. A i rborna fadine j I-131 concentrations were also detected in air i by analyzing charcoal cartridges through which I

air was continuously drawn over a period of one week. Analysis of these cartridges [

i Indicated I-131 levels ranging f rom the normal

, value of <.006 pCl/cu. meter to 0.8 pCl/cu.

meter. This high value is below the Technical Specification Table 3.12.1-2 reporting level of .9 pC1/cu. meter. These results are shown 4 In Figure 0-3 and are consistent with results determined by others in the same general area.

j Concentrations of I-131 in alr are normally not detectable. The dose to a child's thyroid '

, resulting f rom Inhalation of alc containing .8 l i

pCl/ cia. meter over a period of one week is .75 l mrom as calculated using Regulatory Guide 1.109 assumptions and conversions. This Is 4 less than 1% of the annual dose from natural background.

c. Precinitatlan Rain water samples were taken on 05/26/86 and 06/17/86 f rom station 6C1 and f rom 05/19/86 to 05/27/86 from station 13H4. Gamma spectrometry was performed on these samples.

With the exception of Be-7 (f rom cosmic ray activity) and I-131 (17 pCl/1) for the 05/26/86 sample from station 6C1, all nuclides

! searched for were below the ulnimum detectable l l evel s . This concentration of I-131 is at a level which results in a comparatively insignificant dose contribution.

2. Terrestrist

a. [1L]k Additional milk samples were collected weekly j from stations 1081, 17C2, 2581, and 22F1 i

Indina - 131 i

All allk samples were analyzed for concentrations of I-131 (Table 0-VI).

1 Concentrat ions detected' ranged f rom the

! routine value of less than the minimum detectable level (MDL) of .04 pC1/1 to 80

. pCl/1. The Technical Specification Table

! 3.12.1-2 reporting Ilmit for I-131 in milk is

, 3 pCl/1. As depicted in Figure 0-4, the I-131

} concentrations in slik gradually decreased proportional to the half lif e of I-131. Thi s

, Indicates that the deposition of I-131 was i basically a one-time occurrence and the I-131 i had decayed significantly prior to the cloud

of activity passing over again. The i concentrations measured resulting from the Chernobyl accident are consistent with those measured by others within the same general j region. For compari son, as a result of i f allout f rom atmospheric nuclear weapons

! testing by the Peoples Republic of China in J 1976, I-131 concentrations in milk samples j taken f rom the Peach Bottom region ranged up

to 270 pCl/1. During that period (1976) the

! Pennsylvania Department of Environmental l Resources (PA DER) measured concentrations up l to 480 pCl/1. A hypothetical Inf ant consuming milk containing 80 pCl/l for a period of one week would receive 7 mrom to the thyroid as

! calculated using USHRC Regulatory Guide 1.109 assumptions and conversions. This dose is less than 10% of the annual dose from natural l

back groun d.

G- - Snectrometrv In addition to naturally-occurring K-40 and the anticipated I-131 (discussed previously),

concentrations of Cs-137 ranging f rom < 2 pCl/l to 11 pCl/l were detected (Table 0-VII).

The Technical Specification table 3.12.1-2 reporting level for Cs-137 is 70 pCl/1. These concentrations of Cs-137 result in compacitiv61y insignificant dose contributions.

Of particular Interest was station 1081 (goat milk f arm) which showed increased Cs-137 levels of 6-14 pCl/l in the 10/14/86 through 11/24/86 namples (Table C-XIII). Further investigation revealed that a majority of the go at u' diet came f rom stored hay which was purchased and grown locally. Discussions with the hay retailers revealed that the hay purchased by farm 1981 was harvested in the mid-May to June time frame. Therefore, the elevated levels of Cs-137 are expected consequences of the accident at Chernobyl.
