Limerick Generating Station, Units 1 and 2 1994 Annual Radiological Environmental Operating Report Gentlemen:

(

In accordance with the requirements with the Limerick Generating Station (LGS) Unit 1 & 2 Technical Specifications (TS) Section 6.9.1.7, this letter submits the 1994 Annual Radiological Environmental Operating Report No. 11.

This report provides the information delineated in TS Section 6.9.1.7, including a summary of the Radiological Environmental Monitoring Report (REMP).

In assessing the data collected for the Radiological Environmental Monitoring

Program, we concluded that the operation of LGS had no adverse impact on the environment.

The data collected indicated Mn-54 in sediment.

This activity was attributable to LGS operations.

The calculated dose to a teenagers skin from the sediment pathway was 1.63 E-03 mrem /yr which represents 0.01% of the allowable fraction of 10CFR50, Appendix I limits.

The 1994 Radiological Environmental Monitoring Program confirmed that the LGS environmental effects from radioactive releases were well below LGS Technician Specification and other applicable regulatory limits.

If you have any questions, please do not hesitate to contact us.

Sincerely,

Summary and Conclusions l

This report on the Radiological Environmental Monitoring Program conducted for the Limerick l Generating Station by PECO Energy covers the period 1 January 1994 through 31 December l

1994. During that time period,2677 analyses were performed on 2321 samples.

l Surface and drinking (potable) 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. Gruss beta and tritium activities detected were consistent with those observed in other years.

Fish (predator and bottom feeder) anel sediment samples were analyzed for concentrations of No activat.on or fission products were detected in fish samples.

gamma emitting nuclides.

Sediment samples collected below the discharge had Cs-137 concentrations consistent with levels observed in the preoperational years. Statistically significant activity for the activation product Mn-54 was found at downstream location 16C4 (Vincent Dam) during the November collection.

This activity was attributable to LGS operations. The calculated dose to a teenager's skin from the sediment pathway was 1.63 E-03 mrem /yr which represents 0.01% 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 fission or activation products were detected.

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

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. Of the 20 samples analyzed by gamma spectroscopy, only three samples contained trace activities of Cs-137. The activity was not attributable to LGS operations. The fission product Nb-95 was detected at slightly above the minimum detectable activity level and was attributed to statistical variations. No other fission or activation products were found.

Environmental gamma radiation measurements were made monthly and quarterly using 1

1 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 1055 MWe boiling water reactors owned and operated by PECO Energy (PECO), is located adjacent to the Schuylkill River in Montgomery County, Pennsylvania. Unit No. I went critical on 22 December 1984. Unit No.

2 went critical on 11 August 1989. 'Ihe site is located in Piedmont countryside, transversed by On the numerous valleys containing small tributaries which feed into the Schuylkill River.

eastern river bank elevation rises from approximately 110 to 300 feet mean sea level (MSL). On

)

f the wese-n 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 Teledyne Brown Engineering (TB) and Public Service Electric and Gas Company (PSE&G) on samples collected during the period 1 January 1994 through 31 December 1994.

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 expt,ure pathways.

l 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 ISS REMP were collected for PECO Energy by Normandeau Associates, RMC Environmental Services Division (RMC). This section describes l

the collectica methods used by RMC to obtain environmental samples for the LGS l

REMP in 1994. 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 l

o The aquatic environment was examined by analyzing samples of. surface w' ater, j

drinking water, fish, and sediment.- Two gallon water samples were collected I

monthly from continuous samplers located at three surface water locations (10F2, 13B1, and 24S1) and four drinking water locations, (13H2,15F4,15F7, and 28F3),

j One additional drmking water location (16C2) was sampled by compositing wmkly l

grab samples into a monthly sample from January through August. Commencing.

(

with the September sampling a battery operated composite sampler was utilized.

l Controllocations were 10F2,24S1, and 28F3. All samples were collected in new j

unused plastic bottles, which were rinsed at least twice with source water prior to

'l collection. Fish samples comprising the flesh of two groups, catfish / bullhead (bottom feeder) and sunfish (predator), were collected semiannrally it three locations: 16C5 and 20S1 (indicator) and 29C1 (control). Sediment samples composed of recently deposited substrate were collected at three locations semiannually: 16B2 and 16C4 (indicator) and 33A2 (control).

Atmospheric Envimnment The atmospheric environment was examined by analyzing samples of air particulate, airborne iodine, and milk. Air particulate were collected and analyzed weekly at seventeen locations (2B1, 6C1,9C1,10S3,11S1,13C1,13H4,14S1, ISD1,17B1,20D1,22G1,26B1,29B1,31D1.34S2, and 35B1). Controllocations 1 were 13H4 and 22G1. Airborne iodine samples were collected and analyzed weekly from five locations, (10S3,11S1,13C1,13H4, and 14S1). A sixth location (22G1) was added to the Program during the second quarter. Control locations were 13H4 and 22G1. Air particulate and airborne iodine samples were obtained using a vacuum sampler, glass fiber and charcoal filters, respectively. The filters were replaced weekly and sent to the laboratory for analysis. The vacuum

~

samplers were run con *inuously at approximately 1 cubic foot per minute.

Milk samples were collected biweekly at five locations (10B1,19B1,18C1,21B1, and 22F1) during April through November, and monthly during December through March and quarterly at four locations (36E1,9G1,22C1, and 25C1). Locations -

i 9G1 and 22F1 were controls. All samples were collected in new unused two gallon plastic botdes from the bulk tank at each location, refrigerated, and shipped promptly to the laboratory. No preservative was added.

1 Direct radiation measurements were made using thermoluminescent dosimeters

('ILD) consisting of calcium sulfate (CaSO ) doped with dysprosium (Dy). The

. TLD locations were placed on and around the LGS site using a "three ring concept" consisting of:

A site boundary ring consisting of sixteen locations (36S2,3S1, SS1,7S1, i

10S3,11S1,14S1,16S2,18S1, 21S1, 23S2, 25SI, 2653, 29S1, 32SI and i

34S2) near and within the site perimeter representing fencepost doses (i.e., at locations where the doses will be potentially greater than maximum annual i

off-site doses) from LGS release. A middle ring consisting of twenty-seven locations (2B1, 2E1, 4El, 6C1, 7El, 9C1,10E1,10F3,13C1,13El,15DI, 16F1,17B 1,19DI, 20D1, 20F1,:24DI, 25D 1, 26B 1, 28D2, 29B 1, 29E1, 31 D1, 31D2,34El,35B1 and 35F1) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population. And an outer

~

ring consisting of five locations (5H1,13H4,18G1,22G1 and 32G1) extending

)

from approximately 12 to 30 miles from the site and considered to be unaffected by LGS releases.

The specific TLD locations were dwnJned by the following criteria:

c 1.

The presence of relatively dense population; Site meteorological data taking into account distance and elevation for each l

2.

of the 16-221/2 degree sectors around the site, where estimated annual dose

. i from LGS,if any, would be most significant; On hills free from local obstructions and within sight of the vents (where 3.

practical);

And near the closest dwelling to the vents in the prevailing downwind j

4.

direction.

Two TLDs - each comprised of four thermoluminescent phosphors enclosed in l

plastic - were placed at each location in a PVC conduit located approximatelyl three feet above ground level. One TLD was exchanged monthly and the other l

quarterly and sent to the laboratory for analysis.

Data Interpretation The radiological and direct radiation data collected prior to LGS becoming i

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. 'Ihese factors are discussed here to avoid undue repetition in the discussion of the results.

i 1.

Lower Limit of Detection The lower limit _of detection (LLD) was defined as the smallest j

concentration of radioactive material in a sample that would yield a net.

j 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.

2.

Net Activity Calculation and Reporting of Results Net activity for a sample was calculated t y 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 descriptio-f the results calculation, see Appendix E.

Teledyne Brown Engineering (TB) reported all analysis results except gamma spec results as Activity'i 2 Sigma. Public Service Electric & Gas

~

(PSE&G) reported all analysis results except gamma spec as Activity i 1.%

Sigma.

i TB reported all gamma spec results as Activity i 2 Sigma using two conventions (statistically significant and statistically non-significant activity).

A Statistically Significant Activity is calculated activity that is greater than the individual sample's Minimum Detectable Activity and therefore most likely a "true positive result". A Statistically Non-significant Activity is calculated activity that is below the individual sample's Minimum i

Detectable Activity and therefore most likely not_ a "true positive result".

Statistically Non-significam Activity includes calculated " negative activity".'

3 PSE&G yere gamma spec and iodine-131 analyses as Activity i 1.%

Lgma counting statistic when the activity was greater than or equal to the j

1.96 sigma. When an activity was less than the 1.% sigma, the result was -

reported as "< the 1.% sigma value". PSE&G refers to the 1.% sigma.

l value as the individual sample MDA. For specific equations please see Appendix E.

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

l digit in the error term (i.e., 3.62 i 1.23 rounds to 4 i 1: 10.93 i 0. %

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 reponed. Means and standard deviations of these results were calculated.

These standard deviations represent the variability of measured results for different samples '

f rather than single analysis uncertainty. For these calculations, all results i

j reported as < MDA were considered to be at the MDA.

D.

The July TLD from location 20D1 was lost in transit to the laboratory, i

Each program exception was reviewed to understand the causes of the program exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent recurrence. Occasional equipment breakdowns and power l

outages were unavoidable. The numerous equipment problems noted for surface water locations 24S1 and.13B1 were discussed with the sample collection contractor. The major cause of pump failure has been silt build up and a subsequent loss of prime and then pump burn out. Maintenance inspections at j

'hese two locations will be increased to at least twice per week. The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation.

E.

1994 Program Changes A battery operated composite water sampler was installed at location 16C2 (Citizens Utilities) in September. The sampler will be removed when temperatures cause the sampler to freeze. At that time weekly grab samples will be collected for the monthly composite.

Air iodine analyses and quarterly air particulate compositing for gamma spectroscopy analysis was added to location 22Gl. -

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 13B1 could be affected by Station discharges. 'Ihe following analyses were performed.

Gross Beta Samples from all locations were analyzed for concentrations of gross beta I

in the insoluble and soluble fractions (Tables C-I.1 and C-I.2, Appendix C).

Detectable activity was observed in the insoluble and soluble fractions of the surface water samples, ranging from -0.2 to 6 pCi/l for the insoluble fraction and from 2.7 to 10 pCi/l for the soluble fraction. Similar activity levels were observed berecen indicator and control locations for the insoluble aj soluble fractions. the values found were consistent with those found in previous years (Figures C-1 and C-2, Appendix C).

Tritium Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-I.3, Appendix C). Tritium activity ranged from

-20 to 130 pCi/1.

r Gamma Smuirsv Samples from all locations were analyzed for gamma emitting nuclides i

(Table C-1.4, Appendix C). Statistically significant activity _ for naturally occurring K-40 was found in 12 of 36 samples. Potassium-40 results ranged from -70 to 61 pCi/1. Statistically significant activity for Ra-226 and Th-228 was found in only one sample. No statistically significant fission or j

activation products were found.

cosmogenic Be-7; naturally occurring K-40, Ra-226 and Th-228; activation products Mn-54; and fission product Cs-137. The nuclides Th '228 and Pa-226 commonly occur in sediment from daughter decay of natural i

urdmum.

Concectiations of the fission product Cs-137 were found in sediment j

samples from both indicator locations. Location 16B2 had the highest ~

average concentration of 290 pCi/kg dry.. The activity detected was consistent with those observed in the preoperational years (Figure C-6, Appendix C).

Statistically significant activity for the activation product Mn 54 was found at location 16C4 (Vincent Dam) during the November collection. The

.i activity ranged from 10 to 50 pCi/kg (dry).

The calculated dose from this pathway to a teenager's skin was 1.63 E-03 mrem /yr.

This value is based upon the assumption the maximum concentration Mn-54 at the downstream locations was present the entire j

t year. This dose represents 0.01% of the allowable fraction of 10 CFR 50,.

Air Particulates l

Continuous air particulate samples were collected from seventeen locations on a weekly basis. The seventeen locations were separated j

i into three groups: Group I represents locations within the LGS site boundary (10S3,11S1,14S1 and 34S2), Group Il represents locations i

near the LGS site (2B1,6Cl,9C1,13C1,15D1,17B1,20D1,26B1, l

Gross Beta l

Weekly samples were analyzed for concentrations of beta emitters j

(Table C-V.1, Appendix C).

Detectable gross beta activity was observed at alllocations. Companson of results among the three groups aid in determining the effects, if any, j

resulting from the operation of LGS. The results from the On-Site f

i locations (Group I) ranged from 7 to 34 E-3 pCi/m' with a mean of 17 E-3 pCi/m'. The results from the Intermediate Distance locations (Group II) ranged from 6 to 34 E-3 pCi/m' with a mean of 17 E-3 i ;

pCi/m'. The results from the Distant locations (Group IH) ranged from I-7 to 35 E-3 pCi/m' with a mean of 18 E-3 pCi/m'. Comparison of the f

. weekly mean values indicate no notable differences among the three groups (Figurej C-7, Appendix C).

Comparison of the 1994 air.

particulate data with previous years data suggest no effects from the operation of liiS (Figure C-8, Appendix C).

j Gamma Sagemey Weekly samples from six locations (10S3,11S1,14S1,13C1,13H4, and 22GI) were composited and analyzed quarterly for gamma-emitting nuclides (Table C-V.2, Appendix C). Naturally _ occurring Be-7 due to cosmic ray activity was detected in all samples. These values ranged ;

from 60 to % E-3 pCi/m'. Potassium-40, also naturally occurring, was detected in statistically significantly quantities in 10 of 20 samples.

Activity for K-40 ranged from -5 to 37 E-3 pCi/m'. No statistically l

significant fission or activation products were found.

b. Airborne Iodine Continuous air samples were collected from six (10S3,11S1,14S1, 13C1,13H4, and 22G1) locations and analyzed weekly for I-131 (Table

Samples were taken from five locations (10B1,18C1,19B1,21B1 and 22F1) biweekly April through November and monthly-December through March. Samples from four additional locations (9G1, 22C1,

[

25C1 and 36EI) were taken quarterly. The following analyses were j

performed:

l Iodine-131 j

All milk samples from all locations were analyzed for concentrations of l

I-131 (Table C-VII.1, Appendix C). Values ranged from.17 to'.06 pCi/1. All results were below the minimum detectable activity.

i Gamma Smemuy i

Each milk sample from locations 10B1,18C1,19B1,21B1 and 22F1 were analyzed for concentrations of gamma emitting nuclides (Table j

C-VII.2, Appendix C).

E Statistically significant K-40 activity was found in all samples. The

. values ranged from 1100 to 1800 pCi/1.

Statistically significant activity for Cs-137 was found in 3 of 102 samples. Activity for Cs-137 ranged from -2 to 5 pCi/1, Cesium-137 levels have decreased since the Chemobyl accident in 1986.

C.

Ambient Gamma Radiation

.1 Ambient ' gamma radiation levels were measured utilizing CaSOgDy thermoluminescent dosimeters. Forty-eight TLD locations were established around l

the site in a three ring concept for comparison purposes: an " inner ring" of sixteen l

locations around the site boundary; a " middle ring" of twenty-seven locations within a ten mile radius of the site; and an " outer ring" of five locations at distances outside the ten mile radius of the site. Results of TLD measurements are listed in Tables C-VIII.1 to C-VIII.4, Appendix C.

Most of the TLD measurements were below 10 mrad /std. month, with a range of 3.6 to 10.5 mR/std. month for the monthly TLDs and from 3.6 to 8.0 mR/std.

month for the quarterly TLDs. Levels measured were consistent with those observed in previous years (Figure C-9, Appendix C).

The following section 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, Teledyne Brown Engineering (TB) and the quality control laboratory, Public Service Electric & Gas Co. (PSE&G). Comparison of the results for most media were within expected ranges, though occasional differences were seen:

PSE&G's results of gross beta insoluble and soluble in surface and drinking water samples were generally lower than the results from TB (Figures D-1 through D-4, Appendix D). The

-0

- differences were probably due to variations in the respective laboratory's analytical procedures.

PSE&G ashes the sample prior to counting whereas, TB does not.

PSE&G's gross beta results for air particulate samples were higher than TB's results, but the trends were similar for both laboratories (Figures D-5 and D-6). PSE&G uses Sr-90 as a calibration source whereas, TB uses Cs-137.

DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDED AND DISSOLVED FRACTIONS)

Teledyne Brown Enoineerino 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.

1 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 GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDED AND DISSOLVED FRACTIONS)

Public Service Electric & Gas This describes the process used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved.

The sample is mixed thoroughly. Then, a 1.0 liter portion is removed from the surface or drinking water container and filtered through a slow, hardened ashless filter paper mounted in a Buchner funnel. The filter paper is removed from the Buchner funnel, folded into a triangle, placed in a covered porcelain crucible and heated over a Bunsen burner until completely charred. The crucible is then ashed for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> in a muffle furnace at 500* C. The cooled ash is then transferred to a tared stainless steel ribbed planchet using a rubber policeman with laboratory aerosol and reagent water.

The filtrate portion of the sample is evaporated on a hot plate until the volume approaches 20 to 25 ml. At that point, the filtrate is transferred to a tared stainless steel ribbed planchet. Both planchets are evaporated to dryness under an infrared heat lamp. They are subsequently cooled in a desiccator, weighed and counted using a low background gas proportional counter.

J DETERMINATION OF TRITIUM IN WATER BY LIQUID SCINTILLATION COUNTING Tpledyne Brown Enaineerina Ten (10) milliliters of sample is directly pipetted into a 25 mi vial and mixed with liquid scintillation material and counted for a minimum of 100 minutes to determine its activity. The tritium activity is determined by measuring the count rate in the beta activity energy spectrum from 0 to 18 kev. Eighteen to 100 kev represents the carbon-14 energy region, if there is no count rate above background in the carbon-14 energy region, the sample has no contamination and the tritium activity may be calculated directly. If the net count rate in the carbon-14 energy channel is 10% of the tritium count rate or higher, the sample contains contamination that may affect the count rate in the tritium channel, and the sample must be purified by distillation before recounting.

DETERMINATION OF GROSS BETA ACTIVITY.lN AIR PARTICULATE SAMP

' Teledyne Brown Enoineerino l

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 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. 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.

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.

3 The iodine is then stripped from the resin with sodium hypochlorite, reduced with f

hydroxylamine hydrochloride, and extracted into carbon tetrachloride as free iodine.

j it is then back-extracted as iodide into sodium bisulfite solution and is precipitated l

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 l

measuring the stable iodide content of the milk or water with a specific ion electrode.

l Teledyne Brown Engineering dosimeters are rectangular teflon wafers impregnated with 25% CaSO4:Dy phosphor. They are annealed in a hot air oven prior to use l

and are inserted into black polyethylene pouches. The filled pouches are labelled and placed in rectangular holders which contain copper shielding to filter out low l

energy radiation. After exposure in the environment, four separate areas of the i

dosimeter are read in' a Teledyne Brown Engineering model 8300 TLD reader. The dosimeter is then re-irradiated by a standardized Cs-137 source and the four areas are read again. Calculation of the environmental exposure is performed by computer, using the re-irradiation readings to determine the sensitivity of each area of the dosimeter. The reading of control dosimeters are subtracted to allow for 4
