Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Limerick Generating Station by PECO Nuclear covers the period 1 January 1995 through 31 December 1995. During that time period,1120 analyses were performed on 889 samples.
Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No fission or activation products were found. Tritium activities detected were consistent with those observed in other years.
Drinking water samples were analyzed for concentrations of gross beta (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.
Fish (predator and bottom feeder) and sediment samples were analyzed for concentrations of gamma emitting nuclides. Concentrations of I-131 were detected in fish samples from both Control and Indicator locations. Since no other fission or activation products were present, this activity was considered the result of upstream sources. Sediment samples collected below the discharge had Cs-137 concentrations consistent with levels observed in the preoperational years.
Positive activities for the activation products Mn-54, Co-60 and Zn-65 and the fission product 1-!31 were found at downstream locations 16B2 (Linfield Bridge) and 16C4 (Vincent Dam) during the October collection. These activities were attributable to LGS operations. The calculated dose to a teenager's whole body from the sediment pathway was 0.031 mrem /yr which represents 0.15% of the allowable fraction of 10 CFR 50, Appendix I limits.
Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Cosmogenic Be-7 and naturally occurring K 40 were observed at levels consistent with those observed in other years. No ssion or activation products were detected.
High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity.
Cow and goat milk samples were analyzed for concentrations of I-131 and gamma emitting nuclides. All 1-131 results detected were below the minimum detectable activity. Concentrations of K-40 were consistent with those observed in other years. No fission or activation products were found.
1
Environmental gamma radiation measurements were made quaderly using thermoluminescent dosimeters.
Levels detected were consistent with those observed in other years, in assessing all the data gathered for this report and comparing these results with preoperational data, it was evident that, the operation of LGS had no adverse impact on the environment.

Introduction The Limerick Generating Station (LGS), consisting of two 1107 MWe boiling water reactors owned and operated by PECO Nuclear (PECO), is located adjacent to the Schuylkill River in Montgomery County, Pennsylvania. Unit No.1 went critical on 22 December 1984. Unit No. 2 went critical on 11 August 1989. The site is located in Piedmont countryside, transversed by numerous valleys containing small tributaries which feed 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 to approximately 50 feet MSL to the western site boundary.
A Radiological Environmental Monitoring Program (REMP) for LGS 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) and the Branch Technical Position Paper (Rev.1,1979).
The preoperational period for most media covers the periods 1 January 1982 through 21 December 1984 and was summarized in a separate report. This report covers those analyses performed by GPU Nuclear and Teledyne Brown Engineering (TBE) on samples collected during the period 1 January 1995 through 31 December 1995.
A.
Objectives of the REMP The objectives of the REMP are to:
1.
Provide data on measurable levels of radiation and radioactive materials in the site environs.
2.
Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.
l B.
Implementation of the Objectives The implementation of the objectives is accomplished by:
1.
Identifying significant exposure pathways.
2.
Establishing baseline radiological data of media within those pathways.
3.
Continuously monitoring those media before and during Station operation to assess Station effects (if any) on man and the environment.

Program Description A.
Sample Collection Samples for the LGS REMP were collected for PECO Nuclear by Normandeau Associates, RMC Environmental Services Division (RMC).
This section describes the collection methods used by RMC to obtain environmental samples for the LGS REMP in 1995. Sample locations and descriptions can be found in Tables B-1 and B-2, 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. Two gallon water samples were collected monthly from continuous samplers located at two surface water locations (13B1 and 24S1) and four drinking water locations (15F4,15F7, 16C2, and 28F3).
One additional surface water location (10F2) was sampled only during the months when water was taken from the Perkiomen Creek for cooling. Control locations were 10F2, 24S1, and 28F3. All samples were collected in 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 feeder) and sunfish (predator), were collected semiannually at two locations: 16C5 and 2SC1 (control). Sediment samples composed of recently deposited substrate were co"9cted at three locations semiannually: 16B2 and 16C4 (indicator) and 33A2 (control).
Atmospheric Environment The atmospheric environment was examined by analyzing samples of air particulate, airborne iodine, and milk.
Airborne iodine and particulate samples were collected and analyzed weekly at five locations (10S3,11S1, 13C1,14S1, and 22G1). The controllocation was 22G1 Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber fiters attached. The pumps were run continuously and sampled air at the rate of approximately 1 cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis.
Milk samples were collected biweekly at five locations (1081,1981,18C1, 21B1, and 22F1) during April through November, and monthly during i
December through March. Four additional locations (36E1,9G1,22C1, and j
25C1) were sampled quarterly. Locations 9G1 and 22F1 were controls. All 4
I l
l samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, refrigerated, and shipped promptly to the laboratory. No preservative was added.
Ambient Gamma Radiation Direct radiation measurements were mode using Panasonic 801 calcium sulfate (CaSO ) thermoluminescent dcsimaters (TLD). The TLD locations 4
were placed on and around the LGS site ns follows:
A site boundary rino consisting of sixteen locations (36S2,3S1, SS1, 7S1,10S3,11 S 1,13S2,14S1,18 S2, 21 S2, 23 S2, 25 S2, 26 S3, 29S1, 31S1 and 34S2) 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 release.
An intermediate distance rino consisting of sixteen locations (36D1,2E1, 3
4 E 1, 7 E1,10 E1,10F3,13 E1,16 F1,19 D 1, 20F1, 24 D 1, 25 D1, 28 D2, 29 E 1, 31 D2, and 34E1) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.
The balance of eight locations (SH1,6C1,9C1,13C1,15D1,1781,20D1 and 31D1) representing control and special interests areas such as population centers, schools, etc.
f The specific TLD locations were determined by the following criteria:
1.
The presence of relatively dense population; 2.
Site meteorological data taking into account distance and elevation for each of the 16-221/2 degree sectors around the site, where estimated annual dose from LGS, 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 prevailing downwind direction.
Two TLDs - each comprised of two thermoluminescent phosphors enclosed in plastic - were placed at each location in a PVC conduit located approximately three feet above ground level. The TLDs were excnanged quarterly and sent to the laboratory for analysis.
B.
Sample Analysis in order to achieve the stated objectives, the current program includes the following analyses:
1.
Concentrations of beta emitters in drinking water, and air particulates.
2.
Concentrations of gamma emitters in surface and drinking water, air particulates, milk, fish, and sediment.
3.
Concentrations of tritium in surface and drinking water.
4.
Concentrations of I-131 in air and milk.
5.
Ambient gamma radiation levels at various site environs.
C.
Data Interpretation The radiological and direct radiation data collected prior to LGS becoming operational was used as a baseline with which this operational data will be compared. For the purpose of this report, LGS was considered operational at initial criticality. In addition data will be compared to previous years' operational data for consistency and trending. 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.
Lower Limit of Detection and Minimum Detectable Level The lower limit of detection (LLD) 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 LLD 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 LGS detection capabilities for environmental sample analysis.
The minimum detectable level (MDL) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.
6-I
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 result 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.
Data reported in this report were generated using the convention of rounding the result to the same number of significant places as the first significant digit in the error term (i.e.,3.62 i 1.23 rounds to 4 1;
10.93 0.96 rounds to 10.9 i 1.0; -0.01 i 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 occurrence were reported. Means and standard deviations of these results were calculated. These standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.
D.
Program Exceptions For 1995 the LGS REMP had a sample recovery rate of better than 99%.
The exceptions to this program are listed below 1.
Air particulate and air iodine samples were not collected from location 10S3 from week #51 (12/18 to 12/26) due to a sample collection error.
2.
Surface water samples collected at location 24S1 (LGS Intake) were composites of weekly grabs during the weeks of 1/4/95, 2/13/95, 2/22/95, 2/27/95, 3/6/95, 3/13/95, 4/24/95, and 6/5/95 due to equipment or weather problems.
3.
Surface water samples collected at location 1381 (Vincent Dam) were composites of weekly grabs during the weeks of 3/13/95, 9/5/95, 10/23/95,11/13/95, and 11/20/95 due to equipment or weather problems.
4.
Milk samples from farm 10B1 were not available for the months of January, February, October, November and December, and for the last collection of September, because the goats had stopped lactating.
l t
l.
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 recurrence.
Occasional equipment breakdowns and power outages were unavoidable.
The numerous equipment problems noted for surface water location 24S1 were discussed with the sample collection contractor. The major cause of pump failure had been silt build up with a subsequent loss of prime and then pump failure. A backup battery operated ISCO sampler was installed at that location to assist in water collections. In addition, the entire sampling unit was removed and refurbished.
The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation.
E.
Program Changes The following Program changes were made for 1995:
1.
GPU Nuclear became the Primary Analytical Contract Laboratory, replacing Teledyne Brown Engineering (TBE). TBE replaced PSE&G as the QC Laboratory.
2.
Surface Water:
Station 10F2 was changed from a continuous monthly composite sample to a monthly composite sample only when water from the Perkiomen Creek was withdrawn for cooling.
Gross beta analyses were discontinued on all samples.
3.
Drinking Water:
Station 13H2 was discontinued. Electrical power was restored to
' Station 16C2 in May.
4.
Fish:
Fish sampling was discontinued at Station 20S1.
The program currently samples fish populations from upstream and downstream of the LGS discharge.
5.
Air Particulate and Air lodine:
The sampling program was reduced from seventeen locations to five locations.
6.
TLD:
The program was changed from forty-eight TLD locations to forty.
The monthly frequency was discontint:ed. The quarterly sampling frequency was maintained.
in late 1994 a review of the distance and direction from LGS was undertaken using Global Positioning System technology (GPS). The GPS data indicated that several TLD sampling locations near the site I
boundary were in the wrong sector. To assure that coverage in all sixteen sectors was present, some locations were moved and renamed to indicate the correct sector and distance.

Results and Discussion l
A.
Aquatic Environment 1.
Surface Water Samples were taken from a continuous sampler at three locations (10F2,13B1, and 24S1) on a monthly schedule. Of these locations, only 1381 could be affected by Station discharges. The following analyses were performed.
Tritium l
Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-l.1, Appendix C). Tritium activity ranged from -30 to 140 pCi/l.
Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-l.2, Appendix C). Positive K-40 results were found in one of 32 samples. Potassium-40 results ranged from 0 to 40 pCi/l. Positive activity for Ra-226 was found in only one sample. All other nuclides searched for were less than the minimum detectable level.
2.
Drinkina Water Monthly samples were collected from continuous water samplers at four locations (15F4,15F7,16C2, and 28F3). Three locations (15F4, 15F7, and 16C2) could be affected by Station discharges. The following analyses were performed:
i Gross Beta Samples from all locations were analyzed for concentrations of gross beta in the insoluble and soluble fractions (Tables C-II.1 and C-II.2, Appendix C).
The values ranged from -1.3 to 1.1 pCl/l for the insoluble fraction and from 1 to 7 pCi/l for the soluble fraction.
Concentrations detected in both fractions were consistent with those observed in previous years (Figures C-1 and C-2, Appendix C).
-. ~.
l Tritium Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-II.3, Appendix C). Tritium activity ranged from -10 to 130 pCi/l. Similar activity levels were observed at I
all locations.
Gamma Spectrometry Samples from alllocations were analyzed for gamma emitting nuclides (Table C-II.4, Appendix C). Positive 1-131 activity was found in one i
sample from the upstream control location 28F3. -This activity (2.4 1.4) was attributed to upstream sources. An investigation concluded that thyroid treatments are routinely conducted at the Reading Hospital. All other nuclides searched for were less than the minimum detectable level.
3.
Fish Fish samples comprised of catfish / bullhead (bottom feeder) and redbreast /pumpkinseed (predator) were collected at two locations (16C5 and 29C1) semiannually. Location 16C5 could be affected by Station discharges. The following analysis was performed:
Gamma Soectrometry The edible portion of fish samples from both locations was analyzed for gamma emitting nuclides (Table C-Ill.1, Appendix C). With the exception of naturally occurring K-40 and 1-131, no fission or activation l
products were found. lodine-131 activity was found in both upstream Control and downstream Indicator samples collected during the first part of 1995. The 1-131 activity ranged from 0 to 20 pCi/kg (wet) and was attributed to upstream sources. Historical levels of Cs-137 are shown in Figure C-3, Appendix C.
4.
Sediment Aquatic sediment samples were collected at three locations (16B2, 16C4 and 33A2) semiannually. Of these locations, two (16B2 and 16C4) could be affected by Station discharge. The following analysis was performed:
l-11 i
Gamma Spectrometry Sediment samples from all three locations were analyzed for g'amma emitting nuclides (Table C-IV.1, Appendix C). Nuclides detected were i
cosmogenic Be-7; naturally occurring K-40, Ra-226 and Th-228; activation products Mn-54, Co-60, Zn-65; and fission product 1-131 and Cs-137. The nuclides Th-228 and Ra-226 commonly occur in sediment from daughter decay of natural uranium.
Concentrations of the fission product Cs-137 were found in sediment samples from both indicator locations. Location 16B2 had the highest average concentration of 230 pCi/kg (dry). The activity detected was consistent with those observed in the preoperational years (Figure C-4, Appendix C).
Activity for Mn-54 ranged from 10 to' 260 pCi/kg (dry). Cobalt-60 activity ranged from -10 to 120 pCi/kg (dry). Zinc-65 activity ranged from -30 to 290 pCi/kg (dry). The activity from I-131 ranged from -20 to 200 pCi/kg (dry). All activity was attributed to LGS operations.
The calculated dose from this pathway to a teenager's whole body was 3.07 E-02 mrem /yr. This value is based upon the as=.mption the maximum concentrations of Mn-54, Co-60, Zn-65,1-131 and Cs-137 at the downstream locations was present the entire year. This dose-represents 0.15% of the allowable fraction of 10 CFR 50, Appendix I limits.
B.
Atmospheric Environment 1.
Airborne a.
Air Particulates Continuous air particulate samples were collected from five locations on a weekly basis. The five locations were separated
^
into three groups: Group i represek.s locations within the LGS site boundary (10S3,11S1, and 1.tS1), Group ll represents the location at an intermediate distance from the LGS site (13C1),
and Group ill represents the control location at a remote distance from LGS (22G1). The following analyses were performed:.
Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table C-V.1 and C-V.2, Appendix C).
Detectable gross beta activity was observed at all locations.
Comparison of results among the three groups aid in determining the effects, if any, resulting from the operation of LGS. The results from the On-Site locations (Group I) ranged from 5 to 30 E-3 pCi/m' with a mean of 16 E-3 pCi/m. The results from the 8
Intermediate Distance location (Group ll) ranged from 6 to 26 E-3 pCi/m' with a mean of 16 E-3 pCi/m'. The results from the Distant locations (Group til) ranged from 5 to 24 E-3 pCi/m' with a mean of 15 E-3 pCi/m'. Comparison of the weekly mean values indicate no notable differences among the three groups (Figure C-5, Appendix C). Comparison of the 1995 air particulate data with previous years data suggest no effects from the operation of LGS (Figure C-6, Appendix C).
Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma-emitting nuclides (Table C-V.3, Appendix C). Naturally occurring Be-7 due to cosmic ray activity was detected in all samples. These values ranged from 50 to 100 E-3 pCi/m'. All other nuclides searched for were less than the minimum detectable level.
b.
Airborne lodine Continuous air samples were collected from five (10S3,11S1, 14S1,13C1, and 22G1) locations and analyzed weekly for 1-131 (Table C-VI.1, Appendix C).
All results were less than the minimum detectable level and ranged from -20 to 20 E-3 pCi/m'.
2.
Terrestrial a.
Milk Samples were taken from five locations (1081,18C1,1981,2181 and 22F1) biweekly April through November and monthly December through March. Samples from four additionallocations (9G1, 22C1, 25C1 and 36E1) were taken quarterly.
The following analyses were performed:
1 i
lodine-131 J.
Milk samples from all locations were analyzed for concentrations of I-131 (Table C-Vil.1, Appendix C). All results were less than the minimum detectable level and ranged from -0.6 to 0.3 pCi/l.
l Gamma Soectrometry i
Each milk sample from locations 10B1,18C1,1981,2181 and 22F1 were analyzed for concentrations of gamma emitting nuclides (Table ,-Vil.2, Appendix C).
Potassium-40 activity was found in all samples. The values ranged from 1200 to 1700 pCi/l. All other nuclides searched for-were less than the minimum detectable level.
i C.
Ambient Gamma Radiation I
Ambient gamma radiation levels were measured utilizing Panasonic 801 l
(CaSO ) thermoluminescent dosimeters.
Forty TLD locations were i
4 j
established around the site. Results of TLD measurements are listed in i
Tables C-Vill.1 to C-Vill.4, Appendix C.
i All TLD measurements were below 10 mrad /std. month, with a range of 4.1 to 9.3 mR/std. A comparison of the Site Boundary and Intermediate Distance data to the Control Location data, indicate that the ambient gamma radiation levels from the Control Location 5H1 was consistently higher. The i
historical ambient gamma radiation data from Location 5H1 was plotted 3
along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-7, Appendix C). The data indicate that Location SH1 had a historical high bias, but tracked with the data from all three groups.

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 analytical procedures. TBE counts the samples for 50 minutes, GPU counts for 100 minutes.
The gross beta results for air particulate samples collected at the co-located stations 11S1 and 11S2 compared very well (Figure D-3, Appendix D). No significant diferences were noted. Both laboratories use Cs-137 as a calibration source.

DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES I
(TOTAL SUSPENDED AND DISSOLVED FRACTIONS)
GPUN Environmental Radioactivity Laboratory This describes the process used to measure the radioactivity of water samples without identifying the radioactive species present. No chemical 1
separation techniques are involved.
For surface and drinking water samples,400 mls 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 efficiency based on the weight of residue on each planchet.

Teledyne Brown Enaineerina This describes the process used to measure the radioactivity of water samples 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 vacuum through a 0.45 micron Millipore filter. This filter represents the insoluble portion of the sample. The filter is dried and mounted on a planchet.
The filter which represents the soluble portion of the sample is evaporated on a hot plate, and the residue is transferred and dried on another planchet.
l The planchets are counted for 50 minutes in a low-background gas flow proportional counter. Calculation of activity includes a self-absorption correction for counter efficiency based on the weight of residue on each planchet.

DETERMINATION OF TRITIUM IN WATER BY LIQUID SCINTILLATION COUNTING GPUN Environmental Radioactivity Laboratory Seven (7) milliliters of sample is filtered through a 0.45 micron filter into a vial and mixed with 15 mis of liquid scintillation material and counted for a minimum of 480 minutes to determine its activity. The tritium activity is j
determined by measuring the count rate in the beta activity energy spectrum in Region A. 20.0 to 2000 represents Region C. If the sample Region C cpm is within i 25% of the average background Region C cpm and the sample Quench Indicating Parameter (OlP)is within 20 of the H-3 source OIP the sample has no contamination and the tritium activity may be calculated directly. If not the sample must be purified before recounting.

DETERMINATION OF GROSS BETA ACTIVITY IN AIR PARTICULATE SAMPLES Teledyne Brown Enoineerino This describes the process used to measure the overall beta activity of air particulate filters without identifying the radioactive species present. No chemical separation techniques are involved. Each air particulate fitter 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.
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.

DETERMINATION OF l-131 IN MILK SAMPLES Teledyne Brown Enaineerina 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 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 lon electrode.

DETERMINATION OF GAMMA EMITTING RADIOISOTOPES l
Teledyne Brown Enaineerina 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.

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 i
two calcium sulfate and two lithium borate elements. Since each element l
responds to radiation independantly, 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 J
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, j
Only the calcium sulfate elements normally are used for environmental monitoring; however, the lithium borate elements can be used to evaluate l
i 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 i
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 eacn 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 i
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.
E - 16
i 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.

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 Limerick Generating 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 controllimits was investigated. There was no i
evidence to suggest systematic errors.

(a) EPA Results - Expected laboratory precision (control limit i 3 sigma). Units are pCi/ liter for water and milk except K is in mg/ liter. Units are total pCl for air particulate filters.
(b) Results - Average one sigma. Units are pCl/ liter for water and mik except K is in mg/ liter. Units are total pCi for air particulate filters.
(c) No data available. Analysis not performed by laboratory.
i (d) The ERL results were not reported to the EPA. The sample was analyzed six times and the precision of l
the individual results was not acceptable. The ERL policy is to report only highly confident results and since the confidence level could not be achieved from this sample the results were not submitted to the EPA.
l (e) The normalized deviation marginally exceeded the waming level and an apparent trend in the results appeared. The cause was a probable high bias in the beta counting efficiency. Check source control l
charts did not indicate ar#y changes in the counting equipment, so the I-131 calibration was suspected.
l 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 result F-3 l
t
i was in excellent agreement with the EPA (96 pCill versus the EPA value of 100 pCl/l). The discrepancy in the I 131 efficiency between the current calibration and the previous one (aside from the uncertainty in the l
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 7533.331208.17 pCi/l. 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 i
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 j
intemal spikes have been in control. No corrective action is planned at this time.
