! l. Summary and Conclusions

)

l This report on the Radiological Environmental Monitoring Program conducted for the Peach Bottom Atomic Power Station (PBAPS) by PECO Nuclear covers the period 1 January 1995 tnrough 31 December 1995. During that time period,966 analyses were performed on 863 samples.

Surface water samples were analyzed for concentrations tritium and gamma emitting nuclides. No fission or activation products were found. Tritium activities ,

detected were consistent with thoes o,bserved in other years.

~

l Drinking (potable) water samples were analyzed for concentrations of gross beta i (soluble and insoluble fractions), tritium, and gamma emitting nuclides. No fission or activation products were found. Gross beta and tritium activities detected were consistent with those observed in other years.

1 The remaining sample media representing the aquatic environment included fish and sediment samples. These media were analyzed for concentrations of gamma emitters. Fish samples showed no measurable effects from the operation of PBAPS. Sediment Location 4J, located below the discharge, showed the activation product Co-60 which was attributable to PBAPS operations. Cesium-137 activity was found at all locations and was consistent with data from previous  ;

years. The dose to a teenager's skin from the sediment pathway was calculated to be 1.37 E-03 mrem /yr which represents less than 0.01% of the allowable fraction of 10 CFR 50, Appendix l limits.

The atmospheric environment was divided into two parts for examination: airborne and termstrial. Sample media for determining airborne effects included air particulates and air iodine samples. Analyses performed on air particulate samples l included gross beta and gamma spectrometry. The results from both analyses l were consistent with results from the previous years. Furthermore, no notable differences between control and indicator locations were observed. These findings 1 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 activity.

Examination of the terrestrial environment was accomplished by analyzing milk samples for concentrations of lodine-131 and gamma emitters. Results from all analyses were consistent with those from previous years and showed no indication of PBAPS effect.

II. Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, Pennsylvania. The initialloading of fuelinto 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. Shutdown of Peach Bottom Unit 1 for decommissioning was on 31 October 1974. For the purposes of the monitoring program, the beginning of the operational period for Unit 1 was considered to t=

5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report m. PBAPS Units 2 and 3 are boiling water reactors each with a power output of approximately 1102 MWe. The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality was achieved on 16 September 1973, and full power was reached on 16 June 1974. The first fuel was loaded into Peach Bottom Unit 3 on 5 July 1974. Criticality was achieved on 7 August 1974, and full power was first reached on 21 December 1974.

Preoperational summary reports ** for Units 2 and 3 have been previously issued and summarize the results 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. To determine within the scope of the program, any measurable quantity of radioactivity introduced to the environment by the operation of PBAPS.

B. Implementation implementation of the stated objectives is accomplisned 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 any) on man and the environment.

In order to achieve the stated objectives, the current programs include the following analyses on samples collected:

1

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

water, air particulates, milk, fish, and sediment.

3. Concentrations of tritium in surface and drinking (potable) water.

(

4. Concentrations of I-131 in air and milk.
5. Ambient gamma radiation levels at various site environs.

111. Program Description A. Sample Collection This section describes the collection methods used to obtain environmental samples for the PBAPS REMP in 1995. Samples for the PBAPS REMP were collected for PECO by Normandeau Associates, RMC Environmental i Services Division. (RMC). Sample locations and descriptions can be found j l in Table B-1 and Figures B-1 through B-3, Appendix B.

Aauatic Environment The aquatic environment was examined by analyzing samples of surface

! water, drinking water, fish, and sediment. Surface water from two locations (1LL and 1MM) were collected week!y by automatic sampling equipment. l l Drinking water from two locations (4L and 61) were collected weekly from a l tank at each location Buth surface and drinking water samples were each  !

composited into separate modhly samole for analysis. Two quarts of water  ;

are removed from the tank each week and placed into a clean two-gallon j polyethylene bottle to form a monthly composite. Control locations were 1 LL a n d 6 1.

Fish samples comprising the flesh from two groups, catfish (bottom feeder) and smallmouth bass, largemouth bass, or bass (predator) were collected l 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 semiannually at three locations: 4J, 4T (indicators), and 6F (control) using one of two methods, determined by the depth from which the sediment was obtained. In water greater than 4 feet deep, sediment was collected by either a Ponar or Ekman Grab with a surface area of 81 square inches. In shallow water (1-4 feet), sediment was collected by scooping up mud with a plastic bucket.

Atmospheric Environment The atmospheric environment was examined by analyzing airborne and l terrestrial samples. These consisted of air particulates, airborne lodine, and

! milk. Air particulate and air iodine samples were collected and analyzed l weekly from five locations (1B,1Z,2,3A, and 22G1). The control location was 22G1. Air samples were obtained using a vacuum sampler, glass fiber and charcoal filters, respectively. The filters were replaced weekly and sent l

j

5- 1 4

h to the laboratory for analysis. The vacuum samplers were run continuously

at approximately 1 cubic foot per minute. I Milk samples were collected from five locations (A, G, J, N, and O) monthly j

from December through March and biweekly April through November.

j Additionally, samples from six locations (B, C, D, E, L, and P) were collected j'

quarterly. Locations A, B, C, and E were controls. Milk samples were obtained by removing two gallons from the dairyman's bulk tank after mixing.

The sample from each location was therefore a composite of all the milk collected from the dairy herd (from 1 to 3 milkings). The milk was scooped 3 from the agitated bulk tank and placed in new plastic containers.

Ambient Gamma Radiation l Direct radiation measurements were made using Panasonic 801 calcium sulfate (CaSO4 ) thermoluminescent dosimeters (TLD). The TLD locations j were placed on and around the LGS site as follows:

4 A site boundary rina consisting of thirteen locations (1L,1 A,2,11,1C, i 1 J, 1 F, 40, 1NN,1H,1G,1B, and 1E) near and within the site perimeter representing fencepost doses (i.e., at locations where the

  • doses will be potentially greater than maximum annual off-site doses) from LGS releare.'

i '

An intermediate distance rina consisting of nineteen locations (15,22,44,32, 45,14,17, 31 A, 4K, 23, 27, 48, 3A, 49, 50, 51, 26, 68, and 42) extending

~

to approximately 5 miles from the site designed to measure possible exposures to close-in population.

The balance of eight locations (43, 5,16, 24, 46, 47,18, and 19) representing control and special interests areas such as population centers, 4

schools, etc.

j The specific TLD locations were determined by the following criteria:

j 1. The presence of relatively dense population;

2. Site meteorological data taking into account distance and elevation for each of the 36 ten-degree sectors around the site, where estimated annual dose from PBAPS, if any, would be more

~

significant; 4

l

3. On hills free from local obstructions and within sight of the vents I (where practical);
4. Near the dwelling closest to the main stack in the prevailing down wind direction.

A TLD set was placed at each location in a locked formica " birdhouse" or polyethylene jar located approximately six feet above ground level. The TLD ,

sets were exchanged monthly and quarterly, then sent to the laboratory for l analysis.

B. Data Interpretation  ;

Several factors are important in the interpretation of the data. These factors are discussed here to avoid undue repetition in the discussion of the results.

1. Minimum Detectable Level and Minimum Detectable Activity 1

The minimum detectable level (MDL) was defined as the smallest concentration of radioactive materialin a sample that would yield a net count (above background) that would be detected with only a 5%

probability of falsely concluding that a blank observation represents a "real" signal. The MDL was intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criteria for the presence of activity. All analyses were designed to achieve the required PBAPS detection capabilities for environmental sample analysis.

The minimum detectable activity (MDA) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2. Net Activity Calculation and Reportino of Results Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations will rer. ult in sample activity being lower than the background activity '

effecting a negative number. For a more detailed description of the results calculation, see Appendix E.  ;

1 Data reported in this report were generated using the convention of rounding the result to the same number of significant places as the first 1

significant digit in the error term (i.e., 3.62 i 1.23 rounds to 4 i 1; 10.93 i 0.96 rounds to 10.9 i 1.0; -0.01 0.1 rounds to 0.0 i 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 significant positive i occurrence were reported. Means and standard deviations of these results were calculated. These standard deviations represent the l variability of measured results for different samples rather than single i analysis uncertainty. l C. Program Exceptions, For 1995 the PBAPS REMP had a sample collection recovery rate of better than 99%. The exceptions to this program are listed below:

1. Air particulate and air iodine samples from location 1B were not available for week 36.(09/01/95 - 09/08/95) due to a combination electrical and mechanical problems. '
2. Surface water sampler at location 1MM was out of service for the following dates: 03/08/95 to 03/20/95,10/26/95 to 10/27/95, and 12/13/95 to 01/03/96 due to pump electrical, flow or weather problems.

Daily grab samples were taken.

~ 3. Surface water sampler at location 1LL was out of service for the following dates: 12/21/95 to 01/03/96 due to weather problems. Daily grab samples were taken.

4. The fourth quarter TLD from location 19 was found on the ground and its holder destroyed by vandalism. The TLD was not read.
5. Milk farm N went out of business beginning with the October 9,1995 '

sampling. Farm G was substituted for the QC program.

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. Occasional 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 The following are the changes for the 1995 PBAPS REMP:

1

1. GPU Nuclear became the Primary Analytical Contract Laboratory, replacing Teledyne Brown Engineering (TBE). TBE replaced PSE&G as l the QC Laboratory.

l

2. Surface Water:

! Gross beta analyses were discontinued on all samples.

3. Drinking Water:

lodino-131 analysis was discontinued.

4. Air Particulate and Air lodine:

Tritium Samples from both locations were analyzed for concentrations of tritium j (Table C-l.1, Apper; dix C). Results ranged from 70 to 140 pCl/1 and

averaged 100 pCi/l at each location. The concentrations found were l

Potassium-40 results ranged from -3 to 35 pCl/l. No statistically '

significant fission or activation products were found.

2. Drinkina (Potable) Water Samples were collected from two locations monthly (4L and 61). 61 served as the controllocation. The following analyses were performed.

Gross Beta Samples from both locations were analyzed for concentrations of gross beta activity in insoluble and soluble fractions (Tables C-II.1 and C-II.2 and Figures C-1 and C-2, Appendix C). Gross beta activity in the insoluble fraction ranged from -0.9 to 1.4 pCi/1. The values in the soluble fraction ranged from 1 to 4 pCl/1. No differences were observed between the means of the control and indicator stations. The values were generally below those seen in the preoperational period.

Tritium Samples from both locations were analyzed for tritium concentration quarterly (Table C-II.3, Appendix C). The values for the indicator i

i f location (4L) ranged from 60 to 150 pCi/1 with a mean of 100 pCi/1.

L Control location (61) values ranged from -10 to 170 pCi/1 with a mean l of 60 pCi/1.: The concentrations found were lower than those observed during the preoperational period.

l Gamma Spectrometry

3. Fish l

l Samples were collected from two locations semi-annually (4 and 6).

l The control location was 6. The following analyses were performed.

Gamma Soectrometry i

Statistically significant activity was observed only for the nuclide K-40 l which ranged from 2400 to 4000 pCi/kg (wet) (Table C-Ill.1, Appendix C). No statistically significant fission or activation products were found.

Figu's C-3 illustrates the Cs-137 activity for indicator and control locations from the beginning of the operational period through the i l present.

4. Sediment f

Samples were collected from three locations semi-annually (4J,4T and 6F). The control location was 6F. The following analyses were performed.

Gamma Soectrometry Samples from all locations were analyzed for concentrations of gamma j emitters (Table C-IV.1, Appendix C). Statistically significant activity for  ;

Be-7, K-40, Ra-226 and Th-228 was found at alllocations. K-40 results  ;

ranged from 12,000 to 22,000 pCi/kg (dry).

Statistically significant activity for the Plant produced nuclides Co-60  ;

were found in both samples from the indicator location 4J located downstream of the discharge. The results ranged from 0 to 40 pCl/kg

(dry) for the indicator locations and 2 to 10 pCi/kg (dry) for the control

! location. Statistically significant activity from Cs-137 was found at all j locations with a mean value of 230 pCi/kg (dry) for the indicator l - 11. -

l

~

locations and 200 pCi/kg (dry) for the control location. The calculated dose from this pathway to a teenager's skin was 1.37 E-03 mrem /yr.

This value is based upon the assumption the maximum concentrations of Co-60 and Cs-137 at the downstream location (4J) were present the

. entire year. This dose represents less than 0.01% of the allowable j fraction of 10 CFR 50, Appendix I limits. The results were consistent with those from previous years. Figure C-4, Appendix C illustrates the comparison of activities of Cs-137 detected at the control location and i indicator locations from the preoperational period through the present.

l a. Air Particulates  !

L j j

Samples were collected from five locations (18,12, 2, 3A, and ,

l 22G1). Controllocation was 22G1. The following analyses were  !

performed.

Gross Beta Samples from all locations were analyzed for concentrations of gross beta (Tables C-V.1 and C-V.2 and Figures C-5 and C-6, Appendix C). Air particulate locations were divided into three groups: Group I, consisting of 1B,1Z, and 2, located on site at PBAPS; Group 11, comprised of 3A, located at an intermediate  ;

distance from PBAPS; and Group lil, consisting of 22G1, located at a remote distance from PBAPS. Comparison of results among  ;

these three groups aids in determining the effects, if any, resulting i from the operation 'of PBAPS. The results from site location l samples ranged from 4 to 30 E-3 pCi/m*, with a mean of 17 E-3 l pCi/m'. The results from intermediate distance location ranged i from 5 to 27 E-3 pCi/m', with a mean of 16 E-3 pCl/m'. The results i from the distant location ranged from 5 to 24 E-3 pCl/m*, with a mean of 15 E-3 pCl/m'. Comparison of the values indicate no notable difference among the three groups suggesting no effects from operation of PBAPS (Figure C-5, Appendix C).

l Gamma Spectrometry Weekly samples from five locatione (10 1Z,2. 3A, and 22G1) were I

, compcsited and analyzed quaderly for the pesence of gamma j emitters (Table C-V.3). Naturally occurring Be-7 was found in all  ;

i f l

l samples with activity values similar to those from the preoperational years. No statistically significant activation or fission products were detected.

i

, b.' Airborne lodine ,

I Continuous air samples were collected weekly at five locations (18, 12, 2, 3A, and 22G1) and analyzed for 1-131 (Table C-VI.1, Appendix C). No statistically significant I-131 was found.  ;

2. Terrestrial ,
a. Milk Samples were collected from eleven locations (A, B, C, D, E, G, J,

! L, N,0 and P). Farms A, B, C, and E were control locations. The  :

! following analyses were performed.

lodine-131 Samples from all locations were analyzed for concentrations of I-131 (Tables C-Vil.1, Appendix C). All results were less than the minimum detectable level and ranged from -0.3 to 0.2 pCi/l.

I Gamma Soectrometry Samples from five locations were analyzed quarterly for concentrations for gamma emitters (Table C-Vil.2 and Figure C-7, Appendix C). Naturally occurring K-40 was found in all samples with values ranging from 1,300 to 1,500 pCi/l. All other nuclides searched for were less than the minimum detectable activity.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured quarterly at forty locations (as described in the program description section) using Panasonic 801 (CaSO4) thermoluminescent dosimeters (Tables C-Vill.1 through C-Vill.3 and Figures C-8 and C-9, Appendix C). All TLD readings were below 10 mR/std. ,

month with a range of 3.3 to 7.0 mR/std. month.

D-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, GPU Nuclear and the quality control laboratory, Teledyne Brown Engineering (TBE). Comparison of the results for most media were within expected ranges, though occasional differences were seen:

TBE's results of gross beta insoluble and soluble in drinking water samples were slightly higher than the results from GPU (Figures D-1 and D-2, Appendix D). The differences were probably due to variations in the respective laboratory's ar;alytical ,

procedures. TBE counts the samples for 50 minutes, GPU counts for 100 minutes. l 1

The gross beta results for air particulate samples collected at the co-located stations 1Z and 1 A compared very well (Figure D-3, Appendix D). No significant diferences were noted. Both laboratories use Cs-137 as a calibration source. 1 f

GPUN Environmental Radioactivity Laboratorv ,

l This describes the process used to measure the radioactivity of water i samples without identifying the radioactive species present. No chemical  !

separation techniques are involved.

For surface and drinking water samples,400 ml of the sample is filtered under vacuum through a 0.45 micron filter.' This filter represents the insoluble portion of the sample. The filter is dried and mounted on a planchet. The filtrate which represents the soluble 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 100 minutes in a low-background gas flow proportional counter. Calculation of activity includes a self-absorption correction for counter efficiancy based on the weight of residue on each planchet.

DETERMINATION OF TRITIUM IN WATER BY LIQUID SCINTILLATION COUNTING l GPUN Environmental Radioactivity Laboratorv i

i Seven (7) milliliters of sample is filtered tnrough a 0.45 micron filter into a vial  !

l and mixed with 15 ml of liquid scintillation material and counted for a minimum i

of 480 minutes to determine its activity. The tritium activity is determined by  ;

l measuring the count rate in the beta activity energy spectrum in Region A.

l 20.0 to 2000 represents Region C. If the sample Region C cpm is within 25% of the average background Region C cpm and the sample Quench Indicating Parameter (OIP) is within 20 of the H-3 source OlP the sample has no contamination and the tritium activity may be calculated directly.

DETERMINATION OF GROSS BETA ACTIVITY IN AIR PARTICULATE SAMPLES Teledyne Brown Enaineerina This describes the process used to measure the overall beta activity of air l particulate filters without identifying the radioactive species present. No chemical separation techniques are involved. Each air particulate filter is placed directly on a 2-inch stainless steel planchet. The planchets are then counted for beta activity in a low-background gas flow proportional counter. 1 Calculation of activity includes an empirical self-absorption correction curve which allows for the change in effective counting efficiency caused by the residue mass. Self-absorption is not considered in the case of air particulate filters because of the impracticality of accurately weighing the deposit and because the penetration depth of the deposit into the filter is unknown.

i Two liters of sample are first equilibrated with stable lodide 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 weighed 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.

DETERMINATION OF GAMMA EMITTING RADIOlSOTOPES GPUN Environmental Radioactivity Laboratory The procedure for detection of gamma emitting radioisotopes generates high resolution gamma spectra which are used for quantitative determination and identification. Standard geometries have been established to maximize efficiency for sample types: air particulate filters, water, milk, soil / sediment i

and food products. l 1

A description of the analytical methods, beginning with air particulates used for each sample type is presented, followed by the general formula used for calculation of the sample activities.

Air particulate: At the end of each calendar quarter,13 (or 14) weekly air filters from the given location are stacked in a two inch diameter Petri dish in chronological 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 Marinelli beaker. The samples are brought to ambient temperature and counted.

Soil and Sediment: The sample is dried, sieved and put into a counting container and counted.

Food products: The sample is chopped up and put into a counting container and counted.

DETERMINATION OF GAMMA EMnTING RADIOlSOTOPES Teledyne Brown Enoineerino 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 stored on magnetic tape.

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.

The GeLi systems are calibrated for each standard geometry using certified radionuclides standards traceable to the National Bureau of Standards.

l ENVIRONMENTAL DOSIMETRY GPUN Environmental Radioactivity Laboratory GPU Nuclear thermoluminescent dosimeters (TLDS) are Panasonic Type 801 AS badges, two of which are deployed at each station. Each badge contains two calcium sulfate and two lithium borate elements. Since each element responds to radiation independently, this provides eight independent detectors at each station. The calcium sulfate elements are shielded with a thin layer of lead, which makes the response to different energies of gama radiation more linear. The lead also shields the calcium sulfate elements from beta radiation, so that they respond to gamma radiation only. The two lithium borate elements are shielded differently to permit the detection of beta radiation.

Only the calcium sulfate elements normally are used for environmental monitoring; however, the lithium borate elements can be used to evaluate beta exposures or as a backup to the calcium sulfate elements should more data be required.

TLDs are annealed and read using a Panasonic UD701 A TLD Reader equipped with glow curve capture capability. A reader alignment is performed monthly using TLDs irradiated to a known exposure. Run Correction Factors (RCF) are inserted in each read batch to correct for small drifts in reader calibration. An Element Correction Factor (ECF)is generated for each element before a new TLD badge is placed into service to standardize each element to a known exposure. The ECF for each element is updated every two years. Each calcium sulfate element is annealed to a total residual exposure of less than 0.5 mR prior to being issued each time that a badge is used.

Control (transit) badges are issued with every batch of field TLDs and accompany the badges into the field to quantify transit exposure. After the field badges are deployed, the control badges are kept in a lead shield with minimum 2" thick lead during the period of field exposure. Additional control badges are kept in a lead shield for the entire quarter, and receive essentially no transit exposure. All control and field badges are read together at the end of each quarter, and the average field control badge exposure is subtracted from the average shield control badge exposure to generate the transit exposure. The transit exposure (generally less than 1 mR total) is subtracted from the gross exposures on the field badges to yield the net exposures. Net exposures are then converted to mR per standard month. This method of calculating transit exposure conforms to guidance contained in ANSI N545.

f E - 16

Each station comprises two TLD badges, each of which has two calcium sulfate elements. Outliers are identified using predefined algorithms. If all four elements are available, a given exposure value is judged an outlier if the standard deviation exceeds 5% of the mean exposure based on all four elements, and the exposure for one element is outside three standard deviations of the mean exposure based on the other three elements. If only two elements are available, the relative standard deviation based on the two exposure values must be 12% or less, or else both exposure values are considered outliers and no valid data are reported for that station for that quarter. ,

APPENDIX F: QUALITY CONTROL PROGRAM GPU Nuclear (GPU) and Teledyne Brown Engineering (TBE) 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 participation, 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 GPU's and TBE's participation in the EPA cross check program can be found in Table F-1.

(a) EPA ResuRs - Expected laboratory precision (control limit i 3 sigma). Units are pCL/ liter for water and mik except K is in mg/ liter. Units are total pCl for air particulate filters.

(b) Results - Average one sigma. Units are pCi/ liter for water and mik except K is in mg/Itter. Units are total pCi for air particulate filters.

(c) No data available. Analysis not performed by laboratory.

(d) The ERL results were not reported to the EPA. The sample was analyzed six times and the precision of the individual resuRs was not acceptable. The ERL policy is to report only highly confident resuRs and since the confidence level could not be achieved from this sample the results were not submitted to the EPA.

(e) The normalized deviation marginally exceeded the waming level and an apparent trend in the resuRs appeared. The cause was a probable high bias in the beta counting efficiency. Check source control charts did not indicate any changes in the counting equipment, so the 1-131 calibration was suspected.

New l 131 calibrations were performed July 3 through 6,1995 after receiving a new standard from the EPA.

The intercomparison sample data sheets were recalculated with the new efficiencies and the average resut F-3

was in excellent agreement with the EPA (96 pCi/l versus the EPA value of 100 pCi/I). The discrepancy in the 1131 efficiency between the current calibration and the previous one (aside from the uncertainty in the standard) appears to be an abnormally low yield in the preparation of the standard for the older calibration which created a high bias in the counter efficiencies. The bias was less than ten percent, therefore further corrective action or revision of previously reported data is deemed not necessary.

(f) The ERL tritium results were not reported to the EPA in time for the report. The ERL result (average 3 determinations) was 7533.33 i 208.17 pCi/1. The value was within all limits (0.23 sigma of known). Also, the precision (R.A. - 0.318) was acceptable.

(g) The mineral salt content of the water used by the EPA to prepare the samples has been shown to vary substantially throughout the year. Absorption curves to account for mount weight may vary from the true absorption characteristics of a specific sample. Previous results do not indicate a trend toward "out of control" for gross alpha / beta analysis and the normalized deviation from the grand average is only -0.36.

The normalized deviation from the known for TBE-ES does not exceed three standard deviations and intemal spikes have been in control. No corrective action is planned at this time.
