Peach idottom Atomic Power Station Units 2 and 3, 1991 Annual Radiological Environmental Operating Report, Report No. 9 Gentlemen: Attached is she 1991 Annual Radiological Environmental Operating Report No. 9, for the Peach Bottom A+0mic Power Station for the period-January 1,1991 through December 31,1991. This report is submitted in compliance with Appendix A of the Peach Bottom Atomic Power Station Operating License, Section 6.9.2. The Radiological Environmental Monitoring Program found that Peach Bottom's effects on the. environment were not measurable in any sample media except for a small amount of Co-60 activity in one sediment sample. Trace concentrations of Cs-137 were found in the sediment consistent with levels observed in preoperational years. The 1991 Radiological Environmental Monitoring Program confirmed that the environmental effects from radioactive releases were well below Peach Bottom Technical Specifications and applicable regulatory limits.

I I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP) I conducted at the Peach Bottom Atomic Power Station (PBAPS) by Philadelphia Electric Company (PECo) covers the period 1 January 1991 through 31 December 1991. This report combines the results of the programs conducted by Teledyne Isotopes (TI) and Public Service Electric _I and Gas Company (PSE&G)-laboratories. During this period 2,266 analyses were performed on 1,999 samples. I Surface water and drinking (potable) water samples were analyzed for concentrations of gross beta, gama spectrometry, and tritium. Additionally, drinkino water samples were analyzed for concentrations of Iodine-131. Results of these analyses showed no significant differences I between control locations and potentially-affected stations. The values observed were within the ranges noted in the preoperational report. I The remaining sample media representing the aquatic environment included fish and sediment samples. These media wera analyzed for concentrations of gamma emitters. Fish samples showed no measurable effects from the operation of PBAPS. One silt sample located below the discharge showed I Co-60 slightly above the detection limit. The atmospheric environment was divided into two parts for examination: airborne and terrestrial. Sample media for determining airborne effects -I include air particulates and air iodine samples. Analyses performed on air particulate samples includt.d gross beta and gamma spectrometry. The results from both analyses were generally consistent with results from I tne previous years. Furthermore, no notable differences among results from on-site, intermediate, and distant locations in either analysis were observed. These findings indicate no measurable effects from the operation of PBAPS. High sensitivity lodine-131 analyses were performed on weekly air samples. All results were less than the minimum detectable level. Examination of the terrestrial environment was accompli.;hed by analyzing milk samples for concentrations of Iodine-131 and gamma emitters. I Results from all analyses were consistent with those from previous years and no indication of PBAPS effect. I Ambient pmma radiation levels were measured monthly and quarterly throughout the year. Most monthly and quarterly measurements were below 10 mR/std. month. These results were consistent with those from previous years. The operation of the Station had no measurable effect on the environs surrounding Peach Bottom. I I

i l' II. Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Town-ship, York County, Pennsylvania. The initial loading of fuel into Unit 1, a 40 MWe (net) high temperature, gas-cooled reactor, began on 5 February 1966, and initial criticality was achieved on 3 March 1966. g Shutdown of Peach Bottom Unit I for decommissioning was on 31 October g 1974. For the purposes of +he monitoring program, the beginning of the operational period for Unit I was considered to be 5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report "). PBAPS Units 2 and 3 are boiling water reactors each with a power output of approximately 1050 MWe (net). The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality was 3 achieved on 16 September 1973, and full power was reached on 16 ,L ine g 1974. The first fuel was loaded into Peach Bottom Unit 3 on 5 i aly 1974. Criticality was ach eved on 7 August 1974, and full power was f"i[)st reached on 21 December 1974. Preoperational summary reports ( for Units 2 and 3 have been previously issued and summarize the esults of all analyses performed on samples collected from 5 February 1966 through 8 August 1973. A. Objectives The objectives of the REMP are:
- 1. To identify, measure, and evaluate existing radionuclides in the environs of PBAPS site and any fluctuations in radioactivity levels which may occur.
- 2. To monitor and evaluate ambient radiation levels.
- 3. lc determine within the scope of the program, any measurable quantity of radioactivity introduced to the environment by the operation of PBAPS. at E
B. Implementation Implementation of the stated objectives is accomplished by identifying significant exposure pathways, establishing baseline radiological data of media within those pathways, and monitoring those media during plant operation to assess plant effects (if E any) on man and the environment. 5 In order to achieve the stated objectives, the current programs include the following analyses on samples collected:
- 1. Concentrations of beta emitters in surface and drinking water, and air particulates.
- 2. Concentrations of gamma emitters in surface and drinking water, air particulates, milk, sediment, and fish.

Rl JII. Program Description A. Sample Collection f This section describes the collection methods used to obtair i environmental samples for the PBAPS REMP in 1991. Samples for the PBAPS REMP were collected for PEco by RMC Environmental Services, 3; inc. (RMC). g Aauatic Environment The aquatic environment was examined by analyzing samples of surface water, drinking water, fish, and sediment. Surface water from two locations (lLL and IMM) and drinking water from two g locations (4L and 61) were collected weekly from a tank at ehch g location and were compcsited into a monthly sample for analysis. Two quarts of water are removed froni the : ank each week and placed , into a clean two-gallon polyethylene bottle to form a monthly composite. Two additional surface water locations (13A and 138) were collected as monthly grab samples. Control locations were ILL and 61. Fish samples comprising the flesh from two groups, catfish (bottom feeder) and smallmouth bass, largemouth bass, or bass (predator) were collected semiannually at two locations: 4 (indicator) and 6 (control) using several methods such as trapnet, seine or electroshocking. Sediment samples composed of recently deposited substrate were collected ct three locations semiannually: 4J, 4T (indicators), and 6F (control) using one of two methods, determined by the depth from which the sediment is obtained. In water greater than 4 feet deep, sediment is collected by either a Ponar or Ekman Grab with a surface area of 81 squhre inches. In shallow water (1-4 feet), sediment was collected by scooping up mud with a plastic bucket. E E Atmospheric Environment The atmospheric environment was examined by analyzing airborne and terrestrial samples. These consisted of air particulttes, airborne iodine, and milk. Air particulate samples were collected and analyzed weekly from fourteen locations (IB, lZ, 2, 3A, 4A, 5, 6E, 120, 14, 15, 17, 32, 33A, and 38). Control locations were 4A, 6E, and 12D. Air iodine samples were collected from five locations (18, 1Z, 2, 3A, and 12D). Control loa. tion was 120. Air particulate and air iodine samples were obtained using a vacuum sampler, glass fiber and charcoal filters, respectively The filters were replaced weekly and sent to the laboratory for analysis. The vacuum samplers were run continuously at aptroximately 1 cubic foot per minute. I E
I Hilk samples were collected from five locations (A, G, J, N, and
- 0) monthly from December through March and viweekly during the grazing season (April throJgh November). Additionally, samples I from six locations (B C, D, E. L, and M) were collected quarterly. Locations A, B, C, and E were controls. Hilk samples were obtained by removirg two gallons from the dairyman's bulk tank after nixing. The sample from each location is therefore a I composite of all the milk collected from the dairy herd (from 1 to 3 milkings). The milk is uooped from the agitated bulk tank and placed in new plastic containers.
Ambient Gamma Radiation Direct radiation measurements were made using thermoluminescent dosimeters (TLDs) consisting of calcium sulfate (CaS06) dopeo with dysprosium (Dy). Samples were collected from forty seven I locations. The TLD locations were placed on and around the PBAPS site using a "three ring concept": A V,te boundary ring consisting of thirteen locations (18,10,10, I IE, 10, IG, lH, IJ, ll, lH, INN, 2, and 40) near and within the site perimeter, representing fencepost doses (i.e., at locations wbre the doses will be greater than maximum annual off-site dosa) from PBAPS releases; A middle ring consisting of twenty-five iccations (3A, 4K, 5, 68 I 14, 15, 17, 22, 23, 26, 27, 31A, 32, 33A, 38, 42, 43, 44, 45, 46, 47, 48, 49, 50, and 51) extending to approximately ten miles from the site, designed to measure possible exposures to close in population; An outer ring consisting of seven locations (120, 16, 18, 19, 20, - 218, ano 24) extending from approxi.nately 10 to 60 miles from the site, and considered to be unaffected by station releases. Two on site locations (IA and 11), designated as plant complex locations, are not included in any of the three rings. The specific TLD locations were determined by tv following criteria:
- 1. The presence of relatively dense population;
- 2. Site meteorological data taking into account distance and I elevrtior, for each of the 36 ten d: gree sectors around the site, where estimated annual dose from PBAPS, if any, would be more significant;
- 3. On hills free from local obstructions and within sight of the vents (where practical); ,
I I I .
I
- 4. Near the dwelling closest to the main stack in the prevailing j down wind direction.
A TLD set was p!nced at each location in a locked formica l
" birdhouse" or polyethylene jar located anproximately six feet 5' above ground level. The TLD sets were exchangad monthly and quarterly, then sent to the laboratory for analysis.
B. Data Interpretation Several factors are important for interpretation of the data li presented in this report. These factors are discussed here to a' avoid unnecessary repetition in the discussion of the results. The minimum detectable level (MOL) for Teledyne isotopes was defined as the 2 sigma counting statistic and for PSE&G the HDL was defined as the 1.96 sigma. Both definitions represent the ranae of values into which 95% of repeated counts of the same almt would fall. All analyses were designed to achieve the required PBAPS detection capabilities for environmental sample analysis. For a more detailed description of the results a calculation, see Appendix E. g for the analyses gross beta, tritium, and iodine-131 (when e analyzed by beta counting), the activity was reported plus/minus the counting statistic (MDL). This includes calculated negative activity.. for the analyses gamma and iodine 131 (when analyzed by gamma spectroscopy), 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 MOL, the result was reported as *< the MOL value'. Data received from the laboratory were reported using the convention of rounding the result to the same number of significant places as the first significant digit in the error E term (i.e., 3.62 i 1.23 rounds to 4 i 1; 10.93 1 0.96 rounds to g 10.9 i 1.0; -0.01 1 0.1 rounds to -0.0 1 0.1). Results for each type of sample were grouped according to the analyses performed. For gamma analyses, at least those nuclides required for each sample media and nuclides which had a positive occurrence were reported. Means and standard deviations of these results were calculated. These standard deviations represer.t the variability of measured results for different samples rather than single analysis uncertainty, for these calculations, all results reported as < HDL were considered to be at the MDL.

I C. Program Exceptions for 1991 the PBAPS REMP had a sample collection recovery rate of I approximately 98%. The exceptions to this program are listed below: Surface water sampler at location IMM was out of service from I 1. 03/21 to 03/75 due to pump malfunction; from OC/01 to 09/26 due to low river elevation and from 9/26 to 01/02/92 due to pump malfunctions. Daily grab samples were taken.
- 2. Surface water sampler at location ILL was out of service from 05/28 to 06/20 due to a clogged line; from 08/30 tho 09/26 due to low river elevation and from 09/26 to 01/02/92 due to pump I malfunctions. Daily grab samples were taken.
- 3. Surface water collections for location 13B was not performed for March because no water usage was recorded.
- 4. Drinking water sampler at location 4L was out of service from 05/03 to 05/17 due to pump maintenance, from 09/21 to 09/27 I due to cil in the tank and from 10/18 to 10/25 due to pump malfunction. Weekly grab samples were taken.
I 5. Drinkiag water sampler at location 61 was out of service from bl/12 to 01/18, 03/08 to 03/16, and 11/28 to 01/04/92 due to pump malfunctions. Weekly grab samples were taken.
- 6. Air particulate samples were not available from locations 4A and 48 during the weeks of 04/26 to 05/04, 05/04 to 05/10 due to loss of power. And at location 4A from 07/07 to 07/13, I 07/13 to 07/19, 07'M to 07/26 and 08/15 to 08/23 and location 4B from 11/29 to 12/08 due to out of-service equipment.

- 8. Milk Farm M went out of business as of 11/18/91.
- 9. Milk sample from Farm G was not analyzed for 06/14/91 I collection due to mislabelling of the bottle by the sample collector,
,a 10. The MDLs for Ba-140 and La-140 for milk samples collected 'g 06/03/91 for the primary laboratory were not met because the required gamma analysis was not assigned at sample receipt.
- E 11. The MDL for La-140 for water samples collected in May for the
'E quality control laboratory were not met because the laboratory counted the samples after several half-lives had passed. I 7 E I
I Each program exception was reviewed to understand the causes of the program exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent a recurrence. l Occasionci equipment breakdowns and power outages were unavoidable. The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation. , D. Program Changes l The following are the changes for the 1991 PBAPS REMP:
- 1. Clean Harbors Analytical discontinued REMP services bes.:aning in 1991. Public Services Electric and Gas Cempany's laboratory in Maplewood, NJ became the QC laboratory for air llll pat ticulates, surface water and milk beginnirg with the second 1 quarter samples.
- 2. Air particulate location 33A was discontinued. j E\

Samples wer. collected from four locations monthly (ILL, lft9, I 13A and 138). ILL served as the control location. The following analyses were performed. Gross Beta Samples from all locations were analyzed for concentrations of i grost beta in both soluble and insoluble fractions (Table I I C-1.1 and C-1.2 and figures C-1 and C 2). The results for the j soluble fraction ranged from 0.1 to 27 pCi/1. The mean for : the three :adicatoe locations was 3.9 pCi/1, compared to the I mean value c' 3.4 pCi/1 from the control location. The value of 27 pC1/1 t,scurred at location 138 in November. The result was confirmad by recounting. The insoluole fraction of this sample also showed higher retivity as compared to the other I samples collected during N<wemoer. The insoluble fraction showed a larger amount of solids on the planchet than the other samples. Gamma analysis showed no Plant related nuclides present. The results from analysis of the insoluble I portion of all samples from the surface water loc ations ranged frnm -0.3 to 13 pCi/1. The mean of the indicator and control locations were 1.9 pCi/l and 0.8 pCi/1, respectively. Tritium I Samples from three locations (ILL, IMM, 13A) were analyzed for concentrations of aqueous tritium (Table C-l.3). Results ranged from 0 to 240 pCi/l and were within the range found I during the preaperational period. Means from indicator and control locations corrpared well, with values of 80 pCi/l and 100 pCi/1, respectively. l Gamma Spectrometry Samples frot. all locations were analyzed for concentrations of I gamma emitters (Table C-1.4). The nuclides searched for were below the minimum detectable level with the exception of naturally occurring K-40. Potassium-40 was found at all locations and ranged from <4 to 14 pCi/1. I 2.

I Gross Beta Samples from both locations were analyzed for concentrations of gross beta activity in soluble and insoluble f ractions (Tables C-II.1 and C-II.2 and Figures C-3 and C-4). Gross beta activity in the soluble fraction ranged from 0 to 5 pCi/1. The values in the insoluble fraction ranged from -0.3 3 to 2.1 pCl/1. Only slight differences were observed between 3 the means of the control and indicator stations. The values were generally below those seen in the preoperational period. lodine-1)J Samples from both locations were analyzed monthly for 1-131 3 concentrations (Table C II.M.

Gamma Spectrometry Samples from all locations were analyzed for concentrations of gamma emitters (Table C-IV.1). Potassium-40 was found in all I samples ranging from 10 to 23 pCi/g (dry). Plz.nt related nuclide Co 60 was found in one sample near the discharge. The result (0.10 pCi/ gram dry) was slightly above the detection Positive activity from Cs-137 was found at all I limit. locations with a mean value of .18 pCi/g (dry) for the indicator locations and .33 pCi/g (dry) for the control location. Radium-226 and Th-228 activity was found at all I locations. The results were consistent with those from previous years. Figure C-6 illustrates the comparison of activities of Cs-137 detected at the control location and indicator locations from the preoperational period through the I present. B. Atmospheric Environment

- a. Air Particulate 1 Samples were collected from fourteen locations (IB, 12, I 2, 3A, 4A, 5, 6E, 12D, 14, 15, 17, 32, 33A, and 38).
Control locations were 4A, 6E, and 120. The following analyses were performed. Cross Beta Samples from all locations were analyzed for I concentrations of gross beta (Tables C-V.1 and C-V.2 and Figures C-7 and C-8). Air particulate locations were divided into three groups: Group 1, consisting of 18 I lZ, and 2, located on site at PBAPS; Group II, comprised of 3A, 5, 14, 15, 17, 32, 33A and 38, located at intermediate distances from PBAPS; and Group Ill, consisting of 4A, 6E and 120, located at remote distance I from PBAPS. Comparison of results among these three groups aids in determining the effects, if any, resulting from the operation of PBAPS. The results from 3 'E site location samples rangep from 5 to 39 E-3 pCi/m , 5 with a mean of 17 E-3 pCi/m . The results from 3 intermediate locations rangpd from 2 to 47 E-3 pC1/m , with a mean of 17 E-3 pCi/m . The results from distant 11 - lI I
1 I-3 locations rapged from 7 to 40 E-3 pCi/m , with a mean of 18 E-3 pCi/m . Comparison of the mean values indicate no notable difference among the three groups suggesting no effects from operation of PBAPS. S.Amma Spectrometry Samples from five locations (18,1Z, 2, 3A, and 12D) were analyzed quarterly for the presence of gamma emitters (Table C-V.3). Naturally occurring Be 7 was found in all samples with activity values similar to E those from the preoperational years. Potassium 40 was 5 found in approximately half of the samples at or slightly above the detection limit. No Plant related nuclides were detected.
- b. Airborne Iodine Continuous air samples were collected weekly at five locations (IB, lZ, 2, 3A, and 12D) and analyzed for 1-131 (Table C-VI.1). All results were less than the minimum detectable level.

lodine-131 Samples from all locations were analyzed for a concentrations of I-131 (Tables C Vil.1). The values l ranged from -0.34 to 0.1 pCi/1. All results were at or below the minimum detectable level. Indicator and Control farms had an average value of -0.01 and -0.02 pCi/1,respectively. l Gamma Soectrometry Samples from five locations were analyzed quarterly for concentrations for gamma emitters (Table C-VII.2 and Figure C-9). Naturally occurring K-40 was found in all samples with values ranging from 1,100 to 1,500 pCi/1. All other nuclides searched for were less than the minimum detectable level. I l l I B

Most mnnthly and quarterly TLD readings were below 10 mR/std. month with a range of 3.1 to I 12.3 mR/std. month for the monthly's and 2.4 to 8.5 mR/std. month for the quarterly's. No notable differences were observed among site boundary, middle, and outer ring measurements. The data I indicated that operation of PBAPS did not affect the existing ambient gamma radiation levels.

I The following section contains data and figures illustrating the analyses performed by the quality control laboratory. Duplicate samples were obtained from several locations and media and split between the primary laboratory, I Teledyne isotopes (TI) and the quality control laboratory, Public Servic Electric & Gas (PSE&G). Comparison of the results for most media were within expected ranges, though occasional difGrences were seen: PSE&G's results of gross beta insoluble in surface and drinking water samples (Table D-1.2) were generally lower than the results from Teledyne Isotopes (Table C-1.2, Appendix C). The differences were probably due to contrasts in I the respective laboratory's analytical procedures. PSE&G ashes the sample prior to counting whereas. TI does not. PSE&G's gross beta results for air particulate samples were higher than TI's I results, but the trends were similar for both laboratories (Figures D-1 and D 2). PSE&G used Sr-90 as a calibration source whereas, Tl used Cs-137. - I I I I I B I I I I I D-1 1 , I l

I Section 1: Collection Methods Surface and Drinkina Water Samoles Surface and drinking water samples are composited over a one-month period at f,tr locations (ILL, IMM, 4L, and 61). Water is continuously sampled at each location and collected in large tanks. Two quarts of water are removed from the tank each week and put into a clean two-gallon polyethylene bottle to form a monthly composite. At locations 13A and 138 a monthly grab sample is obtained. Air Pa_tlicu hte and Air Iodine Samo191 Air particulate samples are obtained using a system consisting of a pump, a glass fiber filter with a 35-mm diameter orifice, and a running time meter to indicate the total period of operation. At those locations where airborne iodine was also sampled, a charcoal filter was mounted behind the glass fiber filter. The volume sampled for the period is determined from the known flow rate and the running time. At the end of each weekiy air particulate collection period, the air sampling unit is stopped. The filter is then removed from the holder and replaced with a clean filter, and the air sampling unit is returned to operation. Sediment Samolm Sediment samples are collected by one of two methods, determined by the depth from which the sediment is obtained. In water greater than 4-feet deep, sediment is collected by either a Ponar or Ekman Grab with a surface area of 81 square inches. In shallow water (1-4 feet), sediment is collected by scooping a up mud with a plastic bucket or shovel. g Milk Samoles Milk samples are obtained by removing two gallons from the dairyman's bulk tank. The sample from each locat;on is therefore a composite of all the milk from the dairy herd (from 1 to 3 milkings). The milk is scooped from the agitated bulk na tank and placed in new plastic containers. 5 Fish Samoles Fish samples are collected via electroshocking or trap netting. I I I E-2 I a-
I Section 2: Analytical Methods and Calculations I DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDED AND DISSOLVED FRACTIONS) Teledyne Isotopes This describes the process used to measure the radioactivity of water samples I without identifying the radioactive species present. No chemical separation techniques are involved. For surface and drinking water samples, one liter of the sample is filtered under I vacuum through a 0.45 micron Millipote filter. This filter represents the insoluble portion of the sample. The filter is dried and mounted on a planchet. The filter which represents the :;oluble portion of the sample is evaporated on a hot plate, and the residue is transferred and dried on another planchet. The planchets are counted for 50 minutes in a low-background gas flow proportional counter. Calcu'. tion of activity includes a self-absorption I correction for counter effici acy based on the weight of residue on each planchet.

I DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDE0 AND DISSOLVED FRACTIONS) h Eublic Service Electric & Gas This describes the process used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved. The sample is mixed thoroughly. Then, a 1.0 liter portion is removed from the surface or drinking water container and filtered through a slow, hardened ashless filter paper mounted in a Buchner funnel. The filter paper is removed from the Buchner funnel, folded into a triangle, placed in a covered porcelain crucible and heated over a Bunsen burner until completely charred. The crucible is then ashed for at least 2 hours in a muffle furnace at 500 C. The cooled ash is then transferred to a tared stainless steel ribbed planchet using a rubber policeman with laboratory aerosol and reagent water. The filtrate portion of the sample is evaporated on a hot plate until the volume approaches 20 to 25 ml. At that point, the filtrate is transferred to a tared stainless steel ribbed planchet. Both planchets are evaporated to dryness under an infrared heat lamp. They are subsequently cooled in a desiccator, weighed and counted using a low background gas proportional counter.

I I DETERMINATION OF TRITIUM IN WATER BY ELECTROLY11C ENRICHMENT AND LIQUID SCINTILLATION COUNTING Teledyne Isot_opm A 60 ml aliquot is distilled and collected in an Erlenmeyer flask. Approximately 55 g of the distillate is transferred into an electrolytic enrichment cell. One ml of 30% sodium hydroxide solution is added to the cell. The sample is electrolyzed in a 10 C cooling water bath until the volume is 3-4 ml. CO, i s I bubbled through the solution to neutralize the sodium hydroxide. The sample is transferred to a collecting bottle at 80 C and weighed. It is then transferred into a liquid scintillation vial and 20 ml of cocktail is added. The sample is counted for 100 minutes in a liquid scintillation counter. Determination of the Enrichment Factor: Enrichmen tFactor = (final v 1ume) (observed dpm/ml) (initial volume) (standar d dpm/ml) I Aliquots of a tritium standard solution have been enriched to different final volumes to provide a graph of the enrichment factor versus the final volume.

I DETERMINATION OF GROSS BETA ACTIVITY IN AIR PARTICULATE SAMPLES Teledyne Isotooei This describes the process used to measure the overall beta activity of air particulate filters without identifying the radioactive species present. No a chemical separation techniques are involved. Each air particulate filter is placed directly on a 2-inch stainless steel planchet. The planchets are then g counted for beta activity in a low-background gas flow proportional counter. Calculation of activity includes an empirical self-absorption correction curve l which allows for the cSange in effective counting efficiency caused by the 3 residue mass. Self-abso,'ption is not considered in the case of air particulate filters because of the impracticality of accurately weighing the deposit and g; because the penetration depth of the deposit into the filter is unknown. g - Calculation of Sample Activity and 2 Siama Error:

I DETERMINATION OF I-131 IN MILK AND WATER SAMPLES Teledyne Isotopes Two liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin is used to remove iodide from the sample. The iodine is then stripped from the resin with sodium hypochlorite, reduced with hydroxylamine hydrochloride, and extracted into carbon tetrachloride as free iodine. It is then back-extracted as iodide into sodium bisulfite solution and is precipitated as palladium iodide. The precipitate is w'ighed for chemical yield and is mounted on a nylon planchet for low level beta counting. The chemical yield is corrected by measuring the stable iodide content of the milk or water with a specific ion electrode.

I DETERMINATION OF GAMMA EMITTING RADI0IS0 TOPES l Teledyne isotopes Gamma emitting radioisotopes are determined with the use of a lithium drifted germanium (Geli) and high purity germanium detectors with high resolution spectrometry in specific media; such as, air particulate filters, charcoal filters, milk and water. Each sample to be assayed is prepared and counted in standard geometries such as one liter wrap-around Marinelli containers, 300 ml or 150 ml bottles, or 2-inch filter paper source geometries. Samples are counted on large (>55 cc volume) GeLi detectors connected to Nuclear Data 6620 data acquisition and computation systems. All resultant spectra are a stored on magnetic tape. g , The analysis of each sample consists of calculating the specific activities of all detected radionuclides or the detection limits from a standard list of . nuclides.

Standaro geometries have been established to maximize efficiency, for sample types: air particulate filters, water, and milk. A description of the analytical methods, beginning with air partic.11ates used for E each sample type is presented, followed by the general formula used for E calculation of the sample activities. Air particulate: At the end of each calendar quarter,13 weekly air filters from a given location are stacked in a two inch diameter Petri dish in cnronological - order, with the oldest filter at the bottom, nearest the detector, and the newest one on top. The Petri dish is closed and the sample counted. Water and Milk: A well-mixed 3.5-liter sample is poured into a calibrated Marinelli beab r.

l ENVIRONMENTAL 00SIMETRY Teledyne Isotooes Teledyne Isotopes dosimeters are rectangular teflon wafers impregnated with 25% CaSO4:Dy phosphor. They are annealed in a hot air oven prior to use and are inserted into black polyethylene pouches. The filled pouches are labelled and placed in rectangular holders which contain copper shielding to filter out low energy radiation. After exposure in the environment, four separate areas of the dosimeter are read in a Teledyne Isotopes model 8300 TLD reader. The dosimeter is then re-irradiated by a standardized Cs-137 source and the four areas are read again. Calculation of the environmental exposure is performed by computer, using the re-irradiation readings to determine the sensitivity of each area of the dosimeter. The reading of control dosimeters are subtracted to allow for transit dose and system background. A. For any given area of the dosimeter, the dose mR is calculated by the formul a: Dose =~ (R) ( ** *)(avcontrol) where: R = initial reading of the area RR = second reading of the area (after re-irradir. tion) redese = re-irradiation dose in mR avcontrol - average of control values calculated as explained below. If no controls are used, avcontrol - 0 and grnss exposures result B. Each area of each control is calculated by the formula: cdose = ( cr) ( C#*d 8* ) crr where: cdose - control area dose in mR g cr - initial reading of the control area g crr - second reading of the control area (after re-irradiation) credose = re-irradiation dose of the control dosimeter in mR I I E-14 I E
I The average of control values is then calculated from all four areas of all controls by the formula: I 4N [cdose avcontrol = 4, I where: N = total number of control dosimeters C. The average and standard deviation of the area readings for each dosimeter are calculated by standard methods. D. Using the criteria that if one standard deviation is greater than 10% of the average of the four readings and that if the value of one area is outside the range of 3 standard deviations of the average of the other I three areas, then that area will be eliminated and the results will be based on the reir.aining areas.

APPENDIX F: QUALITY CONTROL PROGRAM Teledyne I otopes (TI) and Public Service Electric & Gas (PSE&G) participate in the EPA Radiological Inter-laboratory Comparison (cross check) Program.
'This participation includes a number of analyses on various sample media as found in the Peach Bottom Atomic Power Station REMP. As a result of this particination, an objective measurement of analytical precision and accuracy as well as, a bias estimation of the results are obtained.
Examination of the data shows that the vast majority were within the EPA control limits. Each case of exceeding the control limits was investigated. There was no evidence to suggest systematic errors. The results of TI's and PSE&G's participation in the EPA cross check program can be found in Tables F-1 and F-2, respectively. iI I F-1 I

(a) EPA Results - Expected taboratory precision (3 sigma). Units are pCi/l for water and milk except K which is in mg/t. (b) Teledyne Results - Average 3 sigma. Units are pCi/l for water and milk except K which is in ag/t. Units are total pC' for air particulate fitters. (c) The sanple presents a dif ferent counting geometry. The EPA deposits activity in a 3/4 inch diameter circle, on a plast'c disk approximately 3/32 incl. thick. A special calibration for EPA filters will be performad. The laboratory has c.ateined blank filters f rom the Las Vegas f acility, and will simtate their depcsits. (d) The cause for the deviation is believed to be erroneously high strontim yields, probably caused by inconplete separation of calcim. The laboratory has investigated carrier concentrations and pipeting techniques and have fomd them to be correct. Further aspects of analysts' techniques are being tested. The laboratory has received a new stronti m extraction materiet devetcped at Argonne National Laboratory. Experiments with this method to achieve better separation of calcium were conpleted and procedure PRO-032-105 was implemented on 2/1/92. (e) There is no epparent cause for the low K results. Two other isotopes spiked in the sa@te were in good agreement with EPA values. Unit conversions were reviewed and f omd to be correctly apolied. Possible background errors in geometry were investigated and found to have en insignificent ef fect. (f) Probable f alture to transfer att sanple residue to the counting planchet. Analysts are being tested using Irt-house and other EPA spikes. F- 4 E W M M M E - m m m m
