4HNPREO.REP 1V 1.0 SVMMARY This report presents the results of the Radiological Environmental Monitoring Program conducted during 1994 for the Shearon Harris Nuclear Power Plant (SHNPP)and fulfills the reporting requirements of Technical Specifications 6.9.1.3.The program was conducted in accordance with Technical Specification 4.12.1, the Off-Site Dose Calculation Manual, and applicable procedures.

Approximately 1000 samples of 10 different media types from indicator stations were compared to approximately 210 control samples.In approximately 99 percent of the indicator samples there was no difference from the activities observed in the corresponding control samples.Radioactivity in environmental samples which could be attributed to plant operations in 1994 is as follows: Environmental Media Radio nuclide Location of w/Elighest Annual Mean Activity and Occurrence hfaximum Individual Dose (mrcm/yr)Drinking Water Surface Water Fish H-3 H-3 H-3 Lillington, NC Harris Lake Harris Lake 1,150 pCi/1 (1/12)12,700 pCi/1 (12/12)See above.Assumes H-3 equilibrium between lake water and fish tissue.7.3 F 3 (T.B.)No ingestion pathway.No dose calculated.

3.0 E-2 (T.B.)The radiological environmental data indicates that SHNPP operations in 1994 had no significant impact on the environment or public health and safety.A statistical summary of all the data for 1994 has been compiled and summarized in Table 1-1.The only impact of the plant on the environment during its eight years of operation has been a slow increase in the annual average tritium activity in Harris Lake water from 3.4E+3 pCi/8 in 1987 to 1.3E+4 pCi/8 in 1994.No plant-related gamma activity has been detected in fish collected from Harris Lake or in the community drinking water supply 17 miles downstream at Lillington, N.C.Only once in eight years, in May 1994, UM.FSlREOROlREPU.FS84EENPREO.REP was tritium detected in drinking water/surface water at Lillington, N.C.This result 1,150 J 600 pCi/I appears to be an anomaly since subsequent monthly composite samples were below the LLD of 1000 pCi/1 for the remainder of the year.UALFSUKORGREPQ.FS84IPlPREO.REP 1-2 TABLE 1-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM DATA

3.Refer to Section 4, Missing Samples and Analyses.4.Although quarterly composite samples are required, monthly composite samples are used to provide more frequent and sensitive analyses.UM.FSREORGQKPU.FS84HNPREO.REP 1-6 2.0 GENERAL INFORMATION This section (1)describes the pertinent characteristics of the plant and its environs;(2)provides the details of the monitoring program including sample locations, types, frequencies, and analyses;and (3)presents maps showing the distribution of sampling sites around the plant.2.1 Plant and Location The Shearon Harris Nuclear Power Plant (SHNPP)is a pressurized water reactor designed to produce 860 MWe (net).Criticality was initially achieved on January 3, 1987.The SHNPP site is located in the extreme southwest corner of Wake County, North Carolina.The plant is approximately 16 miles southwest of Raleigh and approximately 15 miles northeast of Sanford.This location is on the northwest shore of Harris Lake which is a 4,000-acre reservoir created by the impoundment of Buckhorn Creek.The reservoir provides process and cooling tower makeup water for the plant and also serves as the receiving body for liquid effluents such-as yard runoff, cooling tower blowdown, and radioactive waste processing system.The main dam for the reservoir is approximately 4.7 miles south of the plant.The spillway at the dam flows into Buckhorn Creek which, after flowing south for approximately two miles, enters the Cape Fear River.There are no industrial or residential structures on CP&L property.Carolina Power&Light cooperates with various state agencies to provide public access for boating, fishing, hunting, and other recreational uses on the property such as boat ramps and access areas.The majority of the land within five miles of the site is wooded with a scattering of fields and residential properties.

Much of the land is used for timber and pulpwood production.

Agricultural activities occur on a limited basis within this area including an operating commercial dairy.The population within ten miles of the plant is, for the most part, considered rural.Towns in this area with notable populations include Apex, Holly Springs, and Fuquay-Varina (see Figure 2-2).UALFSREORGUKPU.FS84HNPREO.REP 2-1 Within a 50-mile radius of the plant, much of the land is devoted to agricultural activity.Major crops include tobacco, soybeans, and corn for grain.Livestock production includes hogs, beef, poultry, and dairy products.Commercial fish and shellfish catches from waters within 50 miles of the station discharge are negligible.

Recreational fishing is popular in the area.Since there are no estuarine or saltwater bodies, sportfishing is confined to freshwater streams, rivers, private ponds, and impoundments such as Harris Lake and Jordan Lake.2.2 Radiolo ical Environmental Monitorin Pro ram The purposes of the SHNPP Radiological Environmental Monitoring Program are to:~Provide an evaluation of the environmental impact and effects on the public of releases of radioactive materials from the plant.~Measure any accumulation of radioactivity in the environment and to assess trends that may be plant-related.

3.0 INTERPRETATIONS

AND CONCLUSIONS 3.1 Air All 309 air cartridge samples from indicator and control stations had I-131 activities which were less than the LLD (see Table 6-1).I-131 was detected in air samples for a six-week period following the Chernobyl incident in April 1986.With this exception, no I-131 has been detected in air samples collected from 1986 through 1994.Gross beta activity was detectable in all airborne particulate samples from the five indicator locations.

The 257 samples had an average concentration of 1.59E-2 pCi/m'value similar to preoperational data and to the 1989-93 values.Similar gross beta activities were observed at the control location in Pittsboro which had an average concentration of 1.64E-2 pCi/m'n 52 samples.No plant-related gamma activity was detected in quarterly composite filter samples from either the indicator or control locations.

Figures 3-1 through 3-5 provide a graphic representation of the gross beta activity'at the indicator locations compared to the control location for the period January through December 1994.3.2~ski W None of the 52 drinking water samples collected at the Lillington Municipal water supply nor the 52 control samples collected from the Cape Fear River above the Buckhorn Dam contained detectable I-131 activity ((0.5 pCi/1)during 1994.This has been the experience for the preoperational and operational period with the exception of 1986 when the fallout from Chernobyl was detected.Figure 3-6 provides graphic representation of the gross beta activity during 1994 for Location 40 (Lillington).

The average monthly gross beta concentrations at the indicator and control locations were similar with activities of 4.86 and 5.30 pCi/1, respectively, similar to the preoperational average of 4.00 pCi/l.UM.FSUKO RARER.FS84HNPREO.REP 3-1 Analyses for gamma-emitting radionuclides indicated all concentrations were less than the lower limit of detection for drinking water.Table 6-1 contains typical LLD values for gamma-emitting radionuclides in drinking water.Tritium was detected in 1 of 12 samples from the Lillington municipal water supply at a level of 1,150 J 600 pCi/1 with an LLD of 1,000 pCi/1.Using the USNRC Regulatory Guide 1.109, Equation A-2 and a one-month exposure to 1,150 pCi/1, the maximally exposed individual would have received a total body dose of approximately 7 E-3 mrem.This was the first observation of H-3 in Lillington drinking water in over 10 years of sampling.Figure 3-7 presents the tritium activities at the sample location versus the control values.3.3 Fish Analyses for gamma-emitting radionuclides in two samples of bottom-feeding fish and in four samples of free-swimming species (sunfish and largemouth bass)from the indicator location, Harris Lake, revealed no detectable activity for 1994 consistent with the data for 1989-1993.

During the Chernobyl period, Cs-134, 137 were detected in both control and indicator samples.Assuming that the fish are in equilibrium with the tritium activity in the lake, the total body dose to the maximum exposed individual due to tritium was calculated by Regulatory Guide 1.109, Equation A-3, to be 0.03 mrem/year.

3.4 Surface Water Surface water samples were collected and analyzed weekly for I-131.Water samples collected during 1994 contained no detectable I-131 (LLD (5E-01 pCi/1)as they have been since plant operations began in 1987.Average gross beta concentrations at the indicator and control locations were similar to the concentrations observed in 1985-1993 indicating no adverse influence from plant operations.

Figures 3-8 and 3-9 provide a graphic representation of the gross beta activity in surface water during 1994 for Locations 26 (Harris Lake)and 40 (Lillington).

UALFSUKORGUKPQ.FS64HNPREO.REP 3-2 Surface water samples were analyzed for gamma-emitting radionuclides and tritium.All concentrations of man-made gamma-emitters were less than their respective lower limits of detection (see Table 6-1).Tritium activity was detectable in the Harris Lake surface water at an annual average concentration of 1.3E+4 pCi/1.This is an increase over the value of 6.4E+3 pCi/I in 1993.Since the surface water tritium activity reflects the activity in fish, it is estimated that the dose to the maximum exposed individual from consuming 21 kg of fish would be 0.03 mrem.Tritium activity was detected in 1 of 12 samples from the Lillington municipal water supply at a level of 1,150+600 pCi/1, with an LLD of 1,000 pCi/l.(See discussion under 3.2 Drinking Water.)Figures 3-10 and 3-11 present the tritium activities in surface water during 1994.3.5 Groundwater Groundwater samples are collected on site at SHNPP and analyzed for gamma-emitting radionuclides and tritium.Concentrations of these radionuclides were all less than their respective lower limits of detection during 1994.Therefore, there is no apparent downwelling of activity.No tritium or gamma-emitter activity has been observed over the period from 1985-1994.

Comparison of the weekly dose rates for TLDs within approximately 2 miles (inner ring)of the plant with those at approximately five miles (outer ring)is presented in Figure 3-12 and shows that the inner ring is only slightly higher than the outer ring and similar to the preoperational period.3.6 Milk During 1994 as in all past years with the exception of the Chernobyl period, no I-131 concentrations were detected in milk samples throughout the entire year.There were also no other gamma-emitting radionuclides from plant operations detected in the milk.3.7 Shoreline Sediment Shoreline sediment samples were collected (1)opposite the discharge structure and (2)near the main dam on four occasions in 1994.No plant-related radioactivity was observed in 1994.No long-term trends are readily identifiable.

However, UM.FSREORGREPQ.FS84HNPREO.REP 3-3 in 1987, three radionuclides Mn-54, Co-58, and Cs-137 were detected in shoreline sediment samples.In 1988, the concentrations of these radionuclides diminished.

In 1989, none of the radionuclides were detected.During 1990, Co-58 and Cs-137 were detected in three of six samples at concentrations only slightly above their respective LLDs.In 1991, Co-58 was detected in five of eight samples at levels ranging from 2.0E-2 to 1.2E-1 pCi/g.In 1992 and 1993, Cs-137 was detected in only one of eight samples at a level of 6.7E-2 and 1.6E-2 pCi/g, respectively.

These results are likely due to sampling variability.

3.8 F~dC In addition to milk sampling, a food product sampling program was maintained.

Various crops were collected during a growing season which basically continued year round.The species selected were primarily broad-leaf vegetables most sensitive to direct fallout of airborne radionuclides.

Crops sampled in 1994 included lettuce, turnip greens, cabbage, collards, broccoli, tomatoes, cucumbers, eggplant, okra, pears, and mustard greens.Gamma spectrometry analyses of the food crops from indicator locations detected no plant-related activity in 39 samples from indicator locations collected in 1994.Fallout Cs-137 has been randomly observed in past years both at the indicator and control locations.

In 1988, Cs-137 was detected at both locations at similar concentrations.

In 1989-1990, no gamma-emitting radionuclides occurred in the control samples.In 1993, Cs-137 was detected in 1 of 23 indicator samples.3.9 External Radiation Ex osure Thermoluminescent dosimeters were used to monitor ambient radiation exposures in the plant environs.The average weekly dose rate from the indicator locations was 1.0 mrem/wk and 1.0 mrem/wk from the control station.The highest indicator location was 4.5 miles NE of the plant and averaged 1.3 mrem/wk.This location also had the hightest annual average in the preoperational period with 1.5 mrem/wk in 1986.The differences among these locations is attributed to variations in soils and local geology and are not the result of plant operations.

4.2~dd C Food crops were not available for sampling during February, March, and April.4.3 TLDs TLDs 3, 17, and 25 were missing in the field during the first quarter collection.

TLD 33 was missing in the field during the fourth quarter collection.

4.4 Use of Global Positionin Satellite S stem Reveals Failure to Monitor for Direct Radiation in One Meteorolo ical Sector Technical Specification 4.12.1 requires TLDs in the inner ring of each of sixteen meteorological sectors.During late 1993, a Global Positioning Satellite System (GPS)was used to verify all environmental sampling locations.

TLD Location 16 was found to be 0.7 mile WSW from the plant site, rather than in the SW sector.This meant that there were two TLDs located in the WSW sector and none in the SW.A new TLD was placed into the SW sector in April 1994.UM.FSUKORGREPU.FS84HNPREO.REP 4-1 5.0 LAND-USE CENSUS 5.1 Introduction Technical Specification 3/4.12.2 for the Shearon Harris Nuclear Power Plant requires that a land-use census be conducted annually around the site.The objective is to evaluate any changes in the use of land which could impact on the radiological health of members of the public.The census employs whatever approach provides the best results, i.e., door-to-door survey, aerial survey, or by consulting local agricultural authorities.

The 1994 land-use census was conducted during July and August.2.2~R Technical Specifications 3/4.12.2 requires that the survey be conducted:

1.Within a five-mile radius of the plant.2.Annually during the growing season.3.In each of the 16 compass sectors to identify the nearest: a.Milk animal.b.Residence.

c.Garden of greater than 500 square feet producing broad-leaf vegetation.

These requirements were supplemented with identification of the nearest meat animals in each of the 16'compass sectors.5.3 Methods In accordance with this guidance, the 1994 land-use census was conducted using a door-to-door survey method.A standard questionnaire was used during an interview to record pertinent data.UALFSUKORGUKPQ.FS84HNPREO.REP 5-1 Resident and road locations were identified within a five-mile radius zone surrounding SHNPP using U.S.Geological Survey topographic quadrangle maps (7.5-minute series).These maps were revised in 1981, based on aerial photo-graphs, and represent recent locations of structures and roads in this locale.Moncure, Cokesbury, Fuquay-Varina, Merry Oaks, New Hill, and Apex quadrangle maps were used.The maps were combined, and five concentric circles at one-mile increments were drawn with the plant at the center.Sixteen compass sectors were created in 22.5-degree increments on the map.Each sector was centered on the compass direction.

Actual site locations were determined using a global positioning system referenced to the SHNPP containment structure.

The combined map was used to identify the nearest residences which were confirmed by field observation.

The nearest garden, milk animal (cow or goat), and meat animal (beef, hogs, or fowl)were located by inspection of fields and residential lots and by interviews with residents within the five-mile radius.The survey was performed by CP&L in July and August during fair weather and good visibility.

The survey started close to the plant in each sector and extended out to the five-mile perimeter.

All roads within the five-mile zone were traveled.Barns, small sheds, and pasture-like fields were observed as indicators of grazing livestock.

These indicators were followed up with an interview of the property owner.In some cases when the owner was not home, a neighbor was interviewed to obtain the desired information.

If this was not possible, the property was either revisited at a later time or information was obtained by visual inspection.

6.0 ANALYTICAL

PROCEDURES 6.1 Gross Beta Gross beta radioactivity measurements are made utilizing a Tennelec Low-Background Alpha/Beta Counting System.The LLD for air particulates is approximately 1.0E-3 pCi/m'or SHNPP samples.Air particulate samples are mounted in 2-inch stainless steel planchets and counted directly.Gross beta activity in drinking and surface waters is determined by evaporating 1 liter of the sample and counting a planchet on a Tennelec Low-Background Alpha/Beta Counting System for 50 minutes.Typical LLD for gross beta is 1.0E+0 pCi/E.6.2 Tritium'Liquid samples requiring tritium analysis are treated with a small amount of sodium hydroxide and potassium permanganate crystals and then distilled.

Five milliliters of the distillate are mixed with thirteen milliliters of liquid scintillation cocktail and counted in a liquid scintillation counter for 50 minutes.The LLD is approximately 1000 pCi/E.6.3 Iodine-131 Iodine-131 airborne concentrations are analyzed by the intrinsic germanium (Ge)spectrometry systems.The cartridges are placed on the detector, and each charcoal cartridge is counted individually with an LLD of 1.9E-2 pCi/m'.Iodine-131 in milk and drinking water is determined by an instrumental method.Analysis involves passing 4 liters over an anion exchange resin and direct gamma analysis of the resin with an intrinsic Ge detector.The LLD using the Ge detector is approximately 0.5 pCi/1 using a 20,000-second count time.6.4 Gamma S ectrometr Gamma spectrum analysis utilizes intrinsic germanium detectors with thin aluminum windows housed in steel and lead shields.The analyzer system is the Canberra Nuclear 9900 Gamma Spectroscopy System.Table 6-1 summarizes UALFSUKORG'PRO'IL.FS84HNPREO.REP 6-1 LLD values derived from instrument sensitivity based upon a blank sample background.

Air particulate filter quarterly composites are placed in a Petri dish and analyzed directly for 1,000 seconds.Liquid samples, except milk, are boiled down to a small volume, transferred to a PB-50 beaker and analyzed for 7,000 seconds.One-liter milk samples are analyzed in a Marinelli beaker for 11,000 seconds.Shoreline and bottom sediments are dried, weighed, and then analyzed in a Marinelli beaker for 1,500 seconds.Food crop and aquatic vegetation samples are weighed wet and analyzed in a Marinelli beaker for 7,500 seconds.Fish samples are cleaned, dressed, and placed in a Marinelli beaker for analysis for 1,500 seconds.6.5 Thermoluminescent Dosimetr Each area monitoring station includes a TLD packet which is a polyethylene bag containing three calcium sulfate phosphors contained in a Panasonic UD-814 badge.The TLD is lighttight and the bag is weather-resistant.

Dosimeters are machine annealed before field placement.

Following exposure in the field, each dosimeter is read utilizing a Panasonic TLD reader.This instrument integrates the light photons emitted from traps as the dosimeter is heated above 150'C.The photons from the lower-energy traps are automatically eliminated through a preheat cycle.Calibration is checked regularly using dosimeters irradiated to known doses.Prior to the measurement of each dosimeter, the instrument is checked through use of an internal constant light source as a secondary standard.The minimum sensitivity of the dosimeters used is approximately 1 mR.The exposure reported is corrected for exposure received in transit and during storage through the use of control dosimeters.

UM.FSUKO REPRO%.FS84HNPREO.REP 6-2 6.6 EPA Laborator Intercom arison Pro ram The Radiochemistry Laboratory at the Harris Energy 4 Environmental Center in New Hill, North Carolina, provides radioanalytical services for CPAL's nuclear plant radiological environmental surveillance programs.In fulfillment of Technical Specification 3/4.12.3, the laboratory is a participant in the EPA cross-check program and uses its performance in this program as a major determinant of the accuracy and precision of its analytical results.During 1994, 47 analyses were completed on 18 samples representing three major environmental media (i.e., water, milk, air filters).Data on the known activities and the normalized standard deviations for the 47 analyses have been received from EPA.A comparison of the average of our reported values with the EPA known activity and its normalized standard deviation is provided below: Standard Deviation From Known Activit 6 1 Standard Deviation (2 Standard Deviation~3 Standard Deviation Percent of Anal ses 55 81 94 Three of 47 samples exceeded the 3 sigma action level.These were a gross alpha in water, a Strontium-89 in water, and a Strontium-89 on a Blind"B" sample.The error on the gross alpha was traced to glassware contamination.

The errors on the Sr-89 in water and the Sr-89 in Blind"B" were traced to the use of SIS quench correction for Cerenkov counting of low activity samples, e.g., EPA.After discussions with the Packard Instrument Company, it was determined that, in contradiction to their manual, SIS quench correction cannot be used for Cerenkov counting of low activity samples.This was corrected by preparing a single point efficiency for extremely low activity samples (SIS values)20 on Tri-carb)and an increase in count time.Reanalyses of EPA sample and low-level spikes showed the problem was corrected.
