Introduction The Limerick Generating Station (LGS), consisting of two 1163 MWe boiling 2

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 l

(MSL). On the western river bank elevation rises to approximately 50 feet MSL to the western site boundary.

3 A Radiological Environmental Monitoring Program (REMP) for LGS was initiated in 1971. Review of the 1971 through 1977 REMP data resulted in the modificatlon 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 1996 through 31 December 1996.

On July 6,1996 a 10CFR20.2002 permit was issued to Limerick for storage of

[

slightly contaminated soils, sediments and sludges obtained from the holding pond, cooling tower and spray pond systems. These materials while in storage i

will decay to background. Final disposition will be determined at decommissioning of the Station.

A.

Objectives of the REMP l-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.

4 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 3-l

---.a e

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).

l This wetion describes the collection methods used by RMC to obtain environmental samples for the LGS REMP in 1996. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1 through B-3, Appendix B.

Acuatic 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, i

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 i

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 29C1 (control). Sediment samples composed of i

recently deposited substrate were collected at three locations semiannually: 16B2 and 16C4 (indicator) and 33A2 (control).

Atmosoheric Environment The atmospheric environment was examined by analyzing samples of air particulate, airborne iodine, and milk. Airborne iodina and particulate samples were collected and analyzed weekly at five locations (10S3, 11S1,13C1,14S1, and 22G1). The control location was 22G1. Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters 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 (9Gl,1981,18C1, and 2181) during April through November, and monthly during December through March. Four additional locations (36E1,22C1,23F1 and 25C1) were sampled quarterly. Locations 9G1 and 23F1 were controls '!

g samples were collected in new unused two gallon plastic bottles irom the o

bulk tank at each location, refrigerated, and shipped promptly to the _p

.-v

l laboratory. No preservative was added.

l Ambient Gamma Radiation Direct radiation measurements were made using Panasonic 801 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations t

were placed on and around the LGS site as follows:

A site boundary rina consisting of sixteen locations (36S2, 3S1, SS1, 7S1, l

10S3,11 S1,13S2,14S1,18S2, 21 S2, 23S2, 25S2, 26S3, 29S1, 31 S1.

i and 34S2) near and within the site perimeter representing fence post doses (i.e., at locations where the doses will be potentially greater than maximum annual off-site doses) from LGS release.

)

l An intermediate distance nna consisting of sixteen locations (36D1, 2E1, j

4E1, 7E1,10E1,10F3,13E1,16F1,19D1, 20F1, 24D1, 25D1, 28D2, 29E1,31D2, and 34E1) extending to approximately 5 miles from the site

)

designed to measure possible exposures to close-in population.

i t

The balance of eight locations (5H1, 6C1, 9C1,13C1,15D1,1781, 2001 and 31D1) representing control and special interests areas such as population centers, schools, etc.

I J

The specific TLD locations were determined by the following criteria:

l 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.

1 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

~

exchanged 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 i

particulates.

2.

Concentrations of gamma emitters in surface and drinking water, air particulates, milk, fish, and sediment.

j 3.

Concentrations of tritium in surface and drinking water.-

j 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 i

discussed here to avoid undue repetition in the discussion of the results.

1.

Lower Limit of Detection and Minimum Detectable Activity The lower limit of detection (LLD) was defined as the smallest concentratica of radioactive material in 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 y

LGS detection capabilities for environmental sample analysis.

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

i l

l 2.

Net Activity Calculation and Reportina of Results 4

Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changer in radioactivity in the environment, background variations will result in sample activity being lower than the background activity sffecting a negative number. For a more detailed description of the result calculations, see Appendix E.

Results for each type of sample were grouped according to the I

i-

- analyses performed. For gamma analyses, fifteen nuclides (Be-7, K-40, Mn-54, Co-58, Fe-59, Co40, Zn-65, Zr-95, Nm-95, Cs-134, Cs-137, Ba-140, La-140, Ra-226 and Th-232) were reported.

Means and standard deviations of these results were calculated.

l These standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.

D.

' Program Exceptions For 1996 the LGS REMP had a sample recovery rate of better than 99%.

The exceptions to this program are listed below:

2 1.

Surface water samples collected at location 24S1 (LGS Intake) were composites of weekly grabs during the weeks of 4/29/96, 11/11/96,12/09/96,12/16/96 and 12/30/96 due to equipment or weather related problems.

2.

Surface water samples collected at location 1381 (Vincent Dam) were composites of weekly grabs during the weeks of 1/29/96, 3/12/96,3/25/96, 5/15/96,7/01/96,7/17/96,7/23/96,10/10/96, 12/09/96 and 12/30/96 due to equipment or weather related i'

problems.

3.

Surface water samples collected at location 10F2 (Perkiomen Creek) were composites of weekly grabs during the week of 6/19/96 due to equipment related problems.

4.

Drinking water samples collected at location 16C2 (Citizen's '

4

. Utilities) were composites of weekly grabs during the weeks of 4/12/96, 4/18/96,12/16/96 and 12/30/96 due to equipment related problems.

l S.

Drinking water samples collected at location 15F7 (Phoenixville) were composites of weekly grabs during the weeks of 10/27/96 and 10/29/96 due to equipment related problems.

i 6.

Milk samples from farm 1081 were not available from January 1 to May 22 and October 8 through December 31,1996, because the f

i goats had stopped lactating.

c J

7.

TLD location 25S2 was vandalized during the second and fourth quarters of 1996. The TLDs were stolen or destroyed.

4 8.

The air particulate filter week no 35 from QC sampling location was lost in transit to the laboratory.

. 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.

1 2

The numerous equipment problems noted for surface water location 1381 were discussed with the sample collection contractor. The major cause of pump failure had been sitt build due to the unusual high flows in the Schuylkill River. The high flows occasionally prevented the use of a t

backup battery operated ISCO sampler. The intake lines were inspected and minor repairs performed by SCUBA divers. Debris which may have caused some of the problems was removed from the line. Additional preventative maintenance is also being performed The overall sample recovery rate indicates that the appropriate i

procedures and equipment are in place to assure reliable program implementation.

E.

Program Changes The following Program changes were made for 1996:

't 1.

Farm 9G1 was moved from the quarterly sampling program to the bi-weekly sampling program replacing farm 22F1 which went out of business on April 23,1996.

[

2.

Farm 23F1 was added to the quarterly milk sampling program on July 2,1996.

Aquatic Environment 1.

Surface Water i

Samples were taken from a continuous sampler at three locations (10F2,1381, and 24S1) on a monthly schedule.. Of these 1

locations, only 1381 could be affected by Station discharges. The

. following analyses were performed.

I Tritium i

i Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-l.1, Appendix C). Tritium activity ranged from -6.6 to 91 pCi/l.

I Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-l.2, Appendix C). One positive K-40 result was i

found out of 31 samples. Potassium-40 results ranged from -15 to r

48 pCl/l. All other nuclides searched for were less than the minimum detectable activity.

2.

Dnnkina 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 i

Gross Beta Samples from all locations were analyzed for concentrations of gross beta in the insoluble and soluble 'ractions (Tables C-II.1 and C-II.2, Appendix C). The values ranged from -2.6 to 1.0 pCill for the insoluble fraction and from -1.9 to 5.8 pCill for the soluble fraction. Concentrations detected in both fractions were consistent with those observed in previous years (Figures C-1 and C-2, j

Ejab Fish samples comprised of catfish /bullhea,d (bottom feeder) and redbreast /pumpkinseed (predator) were collected at two locations (16C5 and 29C1) semiannually. Location 16C5 could be affected i

by Station discharges. The following analysis was perfomied:

Gamma Spectrometrv 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, no fission or activation products were found. The K-40 activity ranged from l

2300 to 3700 pCi/kg (wet). Historical levels of Cs-137 are shown in Figure C-3, Appendix C.

i 4.

Sediment Aquatic sediment samples were collected at three locations (16B2, 16C4 and 33A2) semiannually. Of these locations, two (1682 and 16C4) could be affected by Station discharge._ The following analysis was performed:

Gamma Spectrometry 1

Sediment samples from all three locations were analyzed for

. gamma emitting nuclides (Table C-lV.1, Appendix C). Nuclides detected were cosmogenic Be-7; naturally occurring K-40, Ra-226 l'

and Th-232 and the fission product Cs-137. The nuclides Th-232 and Ra-226 commonly occur in sediment from the daughter decay 4

of natural uranium.

j Concentrations of the fission product Cs-137 were found in f }

sediment samples from both indicator locations. Location 16C2 had the highest average concentration of 210 pCi/kg (dry). The activity detected was consistent with those observed in the i

preoperational years (Figure C-4, Appendix C).

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 represents locations within the LGS site boundary (10S3,11S1, and 14S1),

Group ll represents the location at an intermediate distance from the LGS site (13C1), and Group lli 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 i

emitters (Table C-V.1 and C-V.2, Appendix C).

I l

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 l}

r ranged from 4 to 32 E-3 pCi/m' with a mean of 15 E-3 pCi/m'. The results from the intermediate Distance location (Group ll)' ranged from 4 to 31 E-3 pCi/m' with a mean of 16 E-3 pCi/m. The results from the Distant locations (Group pCl/m'ged from 6 to 30 E-3 pCi/m' with a mean of 16 E Ill) ran

. Comparison of the 1996 air particulate data with previous years data suggest no effects from the operation of LGS (Figure C-5, Appendix C). In addition a comparison of the weekly mean values for 1996 indicate no notable differences among the three groups (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

Mik Samples were taken from five locations (10B1,18C1,1981, 21B1 and 22F1/9G1) biweekly April through November and monthly December through March. Samples from four j

additional locations (9G1/23F1,22C1,25C1 and 36E1) were taken quarterly. The following analyses were performed.

lodine-131 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 activity and i

ranged from -0.22 to 0.11 pCill.

Gamma Spectrometry Each milk sample from locations 1081,18C1,1981, 21 B1 and 22F1 were analyzed for concentrations of gamma emitting nuclides (Table C-Vil.2, Appendix C).

Potassium-40 activity was found in all samples. The values ranged from 1300 to 1900 pCill. All other nuclides searched for were less than the minimum detectable activity.

I Tables C-Vill.1 to C-Vill.4, Appendix C.

All TLD measurements were below 10 mrad /std. month, wit a range of 4.1 to 9.3 mR/std. A comparisen 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 historical ambient gamma radiation data from Location 5H1 l

was plotted along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-7, Appoadix C). The data indicate that Location 5H1 had a historical high bias, but tracked with the data from all three groups.

i The following secten contains data and figures illustrating the analyses performed by the quality control laboratory. Duplicate samples were obtained from severallocations 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:

The gross beta results for the drinking water insoluble and soluble fractions for both GPU and TBE were similar (Figures D-1 and D-2, Appendix D). Any differences noted 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 collocated stations 11S1 and 11S2 compared very well(Figure D-3, Appendix D). No significant differences were noted. Both i

laboratories use Cs-137 as a calibration source.

DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (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 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.

i 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.

i l

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.

DETERMINATION OF TRITIUM IN WATER BY LIQUID SCINTILLATION COUNTING GPUN Environmental Radioactivity Labersters Seven (7) milliliters of sample is filtered through a 0.45 micron filter into a vial and mixed with 15 ml of liquid scintillation material and counted for a minimum of 480 minutes to determine its activity. The tritium activity is 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 cmi and the sample Quench Indicating Parameter (QlP) is within 20 of the H-3 source Ql P the sample has no contamination and the tritium' activity may be calculated directly.

DETERMINATION OF GROSS BETA ACTIVITY IN AIR PARTICULATE SAMPLES Toledyne Brown Enoineenno This describes the process used to measure the overall beta activity of air particulate filters witimut 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 j,

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.

I DETERMINATION OF GAMMA EMITTING RADIOlSOTOPES p

GPUN Environmental Radioactivity Laboratorv i

The procedure for detection of gamma emitting radioisotopes generates high resolution gamma spectra which are uNd for quantitative determination and identification.

Standard geometries have been established to maximize efficiency for sample types:

air particulate filters, water, milk, soil / sediment and food products.

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 i

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.

f ENVIRONMENTAL DOSIMETRY i

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 sulfato elements are shielded with a thin layer of lead, which makes the response to i

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.

i 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 sulfato elements should more data be l

required.

TLDs are annealed and read using a Panasonic UD701 A TLD Reader equipped with r

glow curve capture capability. A reader alignment is performed monthly using TLDs irradiated to a known exposure. Run Correction Factors (RCF) are inseded 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. Eiach calcium sulfate element is annealed to a total residual exposure of less thLn 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 fle!d exposure. Additional control badges are kept in a lead shield for the i

j entire quarter, and receive essentially no transit exposure. All control and field i-badger 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 F

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 conveded to mR per standard month. This method of calculating transit exposure conforms to guidance contained in ANSI N545.

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 i

for that Quarter.

APPENDIX F:

QUALITY CONTROL PROGRAM GPU Nuclear (GPU) and Teledyne Brown Engineering (TBE) participate in the EPA Radiological Comparison (cross check) Program. This participation was limited to analyses of water samples due to budget reductions within EPA. To supplement this program both laboratories contracted with an independent vendor Analytics to provide additional media for analysis. The results of these two Inter-laboratory programs represent the various 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.

i Examination of the data shows that the vast majority were within the EPA or Analytics l

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 participatien in the EPA and Analytics cross check program can be found in Tables F-1, F-2 and F-3.

one standard deviation. Units are pCi/L.

C.

The TBE Cs-134 result is below the control limit. To verify the cause for the deviation, a Cs-134 standard has been purchased. If the Cs 134 efficiency is lower than the efficiency at 604 Kev and 795 Key, then rather than change those efficiencies (which may be needed for other isotopes of comparable energies),

the Cs 134 branching intensity shall be adjusted.

D.

The ERL Sr-90 result is below the control limit. Upon investigation it was found that the background count rate was 2.47 cpm. This was outside of the instrument background control limit and should not have been used. The sampic holders are now being kept clean to prevent reoccurrence.
