==SUMMARY==
The Washington Public Power Supply System Radiological Environmental Monitoring Program (REHP)activities during 1992 are discussed in this report.The objective of the REHP is to determine the radiological impact, if any, of Plant 2 operations on the environment.
To accomplish that objective, air, water, milk, soil, sediment, fish and garden produce samples were collected on a regular basis from the region surrounding the plant.In addition, direct radiation from the plant and plant effluents was measured using thermoluminescent dosimeters (TLDs).Determining whether plant operations significantly affected the environment involved comparison of samples taken in areas near the plant and in other regions which could be potentially impacted by Plant 2 effluents to samples taken in areas that are highly unlikely to be affected.In addition, a comparison of the samples taken during 1992 at locations of potential impact to samples taken at the same location prior to plant operation and during previous periods of operation provided another mechanism for detecting any changes in the environmental radioactivity attributable to Plant 2 operations.
Other methods used to evaluate the REHP results and to bring the results into perspective included comparison of the 1992 results to the lower limits of detection (LLDs)determined for each radionuclide, to the preoperational averages and to the applicable State of Washington or U.S.Nuclear Regulatory Commission investigation or reporting levels or other standards.
Intercomparison programs or studies, through which the accuracy of the REHP analytical results and TLD results are demonstrated, were an important part of the quality assurance activities during 1992.Such intercomparisons tested the performance of the Supply System monitoring program against other monitoring programs and also against known values.The Supply System REHP performed well in the Environmental MeasurementsLaboratory (EHL)and Environmental Protection Agency Intercomparison Studies conducted during 1992.The 1992 results for the routine REHP sampling locations are consistent with the results for previous years.No significant new trends or changes in the environmental levels around the plant were evident at these locations.
The data from two of the special interest stations, the storm drain and the sanitary waste treatment facility, reflect the problems which occurred at those locations during 1992.The Sanitary Waste Treatment Facility received sewage from the U.S.Department of Energy's Fast Flux Test Facility (FFTF).The radionuclides accumulating in its stabilization ponds, cobalt-60, cesium-137, and tritium, remained at low levels and did not exceed any state or federal regulations or standards.
The Plant 2 storm drain pond, however, received radioactive effluents from the plant during the year and the levels of several radionuclides exceeded state and federal limits.A special report was submitted to the Nuclear Regulatory Commission (NRC)in July 1992, documenting the release of radioactivity to the pond in Hay.Subsequent notifications were made to the State of Washington and to the NRC when additional radioactivity or changes in the levels were-observed.Corrective actions were taken by the plant to prevent a recurrence of the May release and to isolate potential sources of radioactivity to the storm drain.Although the levels of radioactivity at the storm drain exceeded some state and federal limits, the radioactivity at the site has no impact on the exposure rate at the site or to member's of the public off-site.The storm drain outfall and pond is within the Plant 2 restricted area and is fenced, so access is limited.The release in Hay and the accumulation of 1-1 radioactivity at the storm drain pond have no impact upon the radiation dose to the public from plant operations.
The other special interest location, the containerized storage area, consisting of large metal containers holding low pressure turbine parts removed during the 1992 maintenance outage, showed no detectable radioactivity, aside from that which is naturally-occurring.

==3.0 INTRODUCTION==
 
The Radiological Environmental Monitoring Program (REHP)for Washington Public Power Supply System Plant 2 provides for the collection and analysis of samples of various environmental media, in order to assess the radiological impact of plant operations.
The environmental media routinely sampled by the REHP include air, water, milk, soil, river sediment, fish, vegetables, fruits, and root crops.Other sample media, such as vegetation and animal products (for example, eggs and meat)are also sampled under special circumstances when additional information about particular radionuclides is needed.The direct radiation near the plant and at various distances from the plant is assessed through the use of thermoluminescent dosimeters.
Although no longer a routine requirement of the REHP, pressurized ionization chambers are also used to assess the direct radiation at various locations.
This annual report is written to satisfy the requirements of Plant 2 Technical Specification 6.9.1.10.The results of environmental measurements made during CY 1992 are presented in the report.The results are discussed and interpreted by comparing them to similar measurements made during the preoperational and previous operational periods and to the detection capabilities associated with the current methods of analysis.The quality assurance and quality control aspects of the program are also discussed in this report.3.1 Site Descri tion Washington Public Power Supply System Plant 2 is located in a sparsely populated shrub-steppe region within the Department of Energy-operated Hanford Site in southeastern Washington.
The plant is approximately three miles west of the Columbia River and is surrounded on all sides by uninhabited desert land.The nearest population centers are Richland, Kennewick and Pasco, which are 12 miles south, 21 miles southeast, and 18 miles southeast, respectively.
The nearest privately-owned lands are located approximately four miles ENE of the plant, across the Columbia River.Given the prevailing wind directions, shown in the 1992 wind frequency distribution in Figure 3-1, the focus of REHP sampling is this farming region across the river.Because Plant 2 is located on the Hanford Site, other sources of radioactive effluents are in relatively close proximity to Plant 2.For this reason, sampling locations near the plant (near-plant locations) provide useful information for separating the potential environmental effects of Plant 2'rom the effects of the other effluent sources on the Hanford Site.3.2 Pro ram Back round The REHP is designed to conform to the regulatory guidance provided by Regulatory Guides 4.1"'nd 4.8'", including the Radiological Assessment Branch Technical Position (BTP)"', while taking into account site specific characteristics.
The quality assurance aspects of the program and the thermoluminescent dosimetry are conducted in accordance with Regulatory Guides 4.15"'nd 4.13"'.The REHP also must adhere to the requirements of the Site Certification Agreement (SCA)'" with the State of Washington and the Plant 2 Technical Specifications'" and the Offsite Dose Calculation Manual (ODCH)"'.These.requirements cover not only the environmental sampling and sample analysis aspects of the program,'ut also the reporting and quality assurance aspects of the program.3-1 The preoperational phase of the program, which extended from March 1978 to January 19, 1984, the date of initial criticality, provided a.baseline of environmental data.Variability in the background levels of radioactivity due to differences in geologic composition, nuclear weapons test fallout, meteorological conditions and seasonal changes is reflected in that preoperational data.REHP environmental samples have always been analyzed by a contract analytical laboratory.
Since June 1986, Teledyne Isotopes, Inc.in Westwood, New Jersey, has performed the analysis of REHP samples.'he thermoluminescent dosimeters used in the REHP to assess the direct radiation are processed by the Supply System External Dosimetry Laboratory within the Health Physics Department.
3.3 Pro ram Ob'ectives The REHP is the final stage in a series of monitoring programs that characterize and analyze the liquid and gaseous effluents from Plant 2.Figure 3-2 presents this monitoring.
hierarchy from the generation of the waste liquids and gases to the calculation of doses from these effluents and the measurement of radioactivity in the environment.
The REHP provides a mechanism for determining whether the levels of radioactivity in the plant environs are within established limits and for ensuring that the accumulation of radionuclides in the environment will not become significant as a result of plant operations.
While in-plant monitoring programs are used to ensure that 10CFR20"'nd 10CFR50"'riteria for releases of radioactive effluents are met, the REHP provides supplemental verification that the concentrations of radionuclides in the environment are not greater than anticipated.
Any radiological effect of Plant 2 on the environment must be distinguished from the normal variation in background radiation levels and from the effects of other sources of radioactive effluents in the area.The monitoring results obtained during each year of the plant's operation are compared to the preoperational data and to data from previous operating years, in order to determine whether a significant accumulation of plant-produced radionuclides has occurred in the environment.
quarterly averages of the results are also compared to the Nuclear Regulatory Commission (NRC)non-routine reporting levels listed in the ODCH.In addition to evaluating the environmental concentrations against federal standards or limits, the REHP also compares the results to state standards"""""".

4.0 PROGRAM DESCRIPTION The REMP plan for Plant 2 is presented in Table 4-1.It summarizes the sample locations, collection frequency and types of analysis performed on the sample media.The methods of sampling and sampling frequencies utilized in the program have been determined by such factors as the half-lives and major exposure pathways for the radionuclides potentially released from the plant to the surrounding environment.
4.1 Sam le Locations Eighty sample locations were included in the 1992 monitoring program.Seventy three indicator and two control, i.e.background, locations were within 10 miles (16 kilometers) of the Plant 2 containment.
Three additional control stations and two indicator stations were outside the 10-mile radius from the plant.Sample stations are listed in Table 4-2 by meteorological sector, sample media and approximate distance from the plant.The numbers and locations of sample stations are based not only on factors such as population distribution and meteorological conditions, but also on station accessibility, security throughout the year and the requirements of applicable regulations.
Other factors such as the need to monitor locations which potentially could be impacted by Plant 2 operations, influence the location of REMP sampling sites.The REMP sampling locations described in Tables 4-1 and 4-2 are presented in Figure 4-1 for sampling locations within the 10-mile radius, except the special interest stations, and in Figure 4-2 for locations outside the 10-mile radius.Figure 4-3 provides a more detailed map of sampling locations in the Sunnyside/Grandview area.Figure 4-4 shows the locations of the storm drain (Station 101), the Sanitary Waste Treatment Facility (Station 102)and the containerized storage area (Station 118), which are special interest stations.Detailed drawings of sampling locations at the storm drain and the containerized storage area are presented in Figures 4-5 and 4-6.The sampling locations for each specific type of sample media are shown in Figures 4-7 through 4-15.4.2 Land Use Census The annual land use census within 5 miles of Plant 2 was performed in August.The objectives of the land use census are to identify the locations of the nearest milk animal, residence and garden greater than 50 m'500 ft)producing broadleaf vegetation and to determine whether any site located during the census has a calculated dose or dose commitment greater than the sites currently monitored for the same exposure pathway.If a new location with a higher dose commitment is found, routine sampling of that dose pathway would be initiated at that new site.The results of the 1992 land use census within 5 miles are given in Table 4-3.No significant changes'from the 1991 census were observed, except that the garden at 4.9 miles E was discontinued.
No milk animals are located within the 5-mile radius.The closest milk locations were at 6.4 miles SE and 7.2 miles ESE.Sheep were located at 4.5 miles NE and cattle are no longer at 4.7 miles ENE.4-1 4.3 Sam lin Hethods The collection of environmental samples for the REHP was performed according to the schedule in Table 4-1.All samples were collected by Supply System personnel.
Documented procedures contained in the Environmental Program Instruction Manual were used for sample collection and preparation.
The following sections describe the Supply System's sampling and preparation methods.4.3.1 Direct Radiation During 1992, thermoluminescent dosimeters (TLDs)were used to determine the direct radiation levels at the fifty-seven (57)monitoring locations shown in Figures 4-7, 4-8 and 4-9.No new TLD locations were added to the program this year, however, the special interest TLD station located at the Haymaker Farm (Station 61)in Franklin County was discontinued in June.The TLD located at Station 9A in Sunnyside served as the control, or background, TLD.The other 56 TLDs served as indicator TLDs.The environmental dosimeter consists of a card containing CaS04.Dy (25%)phosphor in a Teflon matrix.Following oven annealing at 250'C for 2 hours, the 31.75 mm x 44.75 mm x 0.4 mm thick card was loaded into a plastic case (Teledyne Model EB-2)lined with.0.58 mm copper (520 mg/cm')to lessen the TLD's over-response to low energy photons"".
The TLD was prepared for the field by first wrapping the case with aluminum foil, sealing it in two plastic bags and finally placing'it in a cotton bag, which was hung from a metal post at each site.The TLDs were hung approximately three feet above the ground.Two sets of TLDs were employed at each location.One set was exchanged on a quarterly basis and the other exchanged on an annual basis.Exposure of the field TLDs during transport to the TLD sites was monitored by a set of field control, or trip control, dosimeters that accompanied the field dosimeters to and from the field locations.
Another set of TLDs was used as building control TLDs which were used to determine the exposure of the TLDs if they remained in the lead cave during the entire quarter.The TLD exposure during transport to and from the field was determined by subtracting the difference between the building control results and the trip control results.The environmental dosimeters were processed on a Teledyne Isotopes Model 9100 Automatic Reader.Following the initial processing, the field dosimeters were annealed and given a calibration exposure of 100 mR of cesium-137 gamma, in order to determine response (i.e, calibration) factors for each dosimeter.
The calibration factors were then used to determine the total exposure received by each TLD.The exposure values determined for calibration exposures, as well as the exposures of the gA dosimeters (processing control dosimeters) and audit dosimeters (spiked dosimeters), were based on the calculated, field strength of the encapsulated cesium-137 source.The calculated field strength of the source was determined from National Institute of Standards and Technology (NIST)-traceable ionization chamber measurements made over a period of several years during the routine use and calibration of the source.Ionization chamber measurements made during TLD calibration were used to confirm the calculated exposure.If the calculated exposure and the ionization chamber reading differed by 5%or more, an investigation was performed into the calibration exposure.O.0 4-2 Three Reuter Stokes pressurized ionization chambers (PICs)provide an additional
,'apability for measuring direct radiation exposure.These units are no longer part of the routine monitoring program, but they are used in special monitoring situations and maintained as back-up monitoring systems.Solar panels provide the power sources for the units in order to prevent equipment problems and damage caused by power surges and lightning.
4.3.2 Airborne Particulate/Iodine Air particulate and air iodine (I-131)samples were obtained thr ough the use of portable, low volume (1.5 cfm)constant flow-rate sampling units at each of twelve locations.
The samples drawn at Station 9A (Figure 4-3)were considered control samples;the ones drawn at the other locations (Figure 4-10)were indicator samples.Air particulates were collected by drawing air through a 47mm-diameter glass fiber filter.Air iodine was collected by drawing air through a 57mm-diameter TEDA-impregnated charcoal cartridge.
The particulate air filter and charcoal cartridge were placed in tandem, particulate filter first, in a holder that attached to the air inlet of the sampler unit.The sampler units were placed in ventilated metal weatherproof housings mounted on elevated platforms at each air sample location.The air sampler units were run continuously, with the filter and charcoal cartridge exchanged weekly for analysis.The total sample time for each filter and cartridge was recorded from the elapsed time indicator and the sample volume was calculated and recorded.The filters and cartridges were shipped or delivered to the analytical contractor within one or two days of collection.
4.3.3 Water The water sampling network consisted of nine sampling locations:
three for the evaluation of river/drinking water, one for discharge water, three for ground water, one for the storm drain water, and one for the sanitary waste water.The locations of these sampling sites are shown in Figures 4-4, 4-5, 4-11, and 4-12.The sampling locations at the storm drain and the sanitary waste treatment facility are shown in Figures 4-12 and 5-17.One river/drinking water location, Station 26, was used for evaluation of the plant intake water, i.e., the river water taken upstream of the plant discharge point.This Station 26 sample can be consid'ered a drinking water sample since the site draws its drinking water from the intake water.It is considered the river/drinking water control sample because of its upstream location.Two additional locations, Stations 28 and 29, were used to evaluate the water at the two nearest drinking water.locations,.the, Department of Energy 300 Area and the Richland Water Treatment Plant.These two stations were considered indicator stations.The ODCH requirement for a downstream water sample"near but beyond the mixing zone" was met by sampling water from Station 27, the plant discharge line to the Columbia River.This sample reflects the radioactivity present in the plant discharge prior to any river dilution, rather than the concentrations that would be found after dilution in the mixing zone.Water is drawn at this location because it was not feasible to perform flow-proportional composite sampling in the mixing zone area of the river downstream from the plant discharge point.This Station 27 sample is also considered an indicator sample.TEDA: Triethylene diamine 4-3 0'omposite samplers are installed at the two drinking water locations (Stations 28 and 29)and the control location (Station 26)to periodically collect 25-ml aliquots of water at a regular time interval.These aliquots are added to large collection bottles.At the prescribed intervals, the sampler collects, alternately, an aliquot for the sample designated for gross beta and gamma isotopic analyses and an aliquot for the sample designated for tritium analysis.Two composite samplers draw samples from the discharge line (Station 27).They operate in a flow-proportional mode through a complex system that adjusts the'ampling frequency relative to the flow rate in the discharge line.Only one of the samplers operates at any given time, while the other sampler is maintained ready to use when needed.Prior to the start of each monthly sampling period, concentrated nitric acid was added to the large collection bottles receiving the gross beta and gamma isotopic water samples to inhibit biological growth and plateout of dissolved ions on the bottle wall.Acid was not added to the collection bottles receiving the water samples for tritium analysis.One gallon of each of the gross beta samples was poured into a clean plastic cubitainer each month.A 250-ml cubitainer was used to hold the monthly sample submitted for the quarterly tritium composite.
Nonroutine analyses on the drinking water samples include strontium-90 analysis, when the gross beta activity exceeds 8 pCi/liter or ten times the mean of the previous three months'ctivity for a specific location, and iodine-131 analysis, when the dose calculated for the consumption of water exceeds one mrem per year.Neither of these analyses were required during 1992.The three groundwater stations are located on Supply System property: one well on the Plant 2 site (0.I mile north of the Reactor Building)and two wells on the WNP-I site (1.2 miles downgradient from Plant 2).These locations are shown in Figure 4-12.Water from the Plant 2 well can be used as a backup source for drinking and fire protection.
Water from the WNP-I wells supplies the drinking and fire protection water for the WNP-I site.All three groundwater samples are considered indicator samples.quarterly grab samples were taken from each of these wells.One gallon was collected from each well for gamma analysis and 250 ml was drawn for tritium analysis.The gamma analysis samples were acidified with nitric acid.The tritium samples were left unacidified.
Water samples were also collected from two special interest locations, the storm drain, Station 101, and the Sanitary Waste Treatment Facility (SWTF), Station 102.Until, November, grab samples were taken from the water at these two locations on a frequency ranging from daily to quarterly, depending upon sampling need.In November a composite water sampler was installed at the outfall of the storm drain pipe, so aliquots were collected on an hourly basis to form a daily composite sample.These aliquots were collected hourly regardless of flow through the pipe.Flow measurement devices will be installed at the pipe outfall during 1993, so that aliquots can be collected on a flow-proportional basis.Sanitary pond water samples, however, have continued to be grab samples.Storm drain and sanitary waste water samples were acidified and handled as described above for the other types of water.-
4.3.4 Soil Soil samples were collected once during 1992, from four locations required by the Site Certification Agreement.
The four locations (Stations 1, 7, 21 and 23)are shown in Figure 4-13.One sample was taken at the control location, Station 9A (Figure 4-3).quarterly soil samples were collected at two special interest locations, Station 101 and Station 118, as shown in Figures 4-4, 4-5 and 4-6.Two additional samples were collected at the Haymaker Farm (Station 61)located at 6.5 miles southeast of Plant 2.This sampling was performed at the owner's request.Each sample was taken from an area of approximately one square foot and a depth of approximately one inch.Approximately two kilograms of soil were used in each sample.Soil samples were shipped to the analytical contractor within ten working days after collection and analyzed for gamma activity.If the gamma isotopic analysis indicated that cesium levels in any of the indicator samples exceeded ten (10)times the level in the control sample, a strontium analysis was performed on the sample(s).
During 1992, strontium analysis was required for Station 23 soil sample only.4.3.5 Sediment-0 Sediment samples were collected twice during 1992 from two sampling locations along the Columbia River.The upstream sediment sample (Station 33)was collected from a location approximately two miles up the Columbia River from the plant discharge point.The downstream sample location (Station 34)was collected from a location approximately one mile downstream of the discharge point (Figure 4-14).Samples were scooped from under water near the river shoreline.
Each sample consisted of approximately two kilograms of the shallow surface sediment.The samples were placed in clean plastic bags and shipped to the analytical contractor within a day or two of collection.
Sediment samples were also taken from the outfall and pond bed of the storm drain pond and the settling ponds, dosing pond, percolation bed, and overflow basin at the Sanitary Waste Treatment Facility.Sediment sampling in these locations was performed in a similar manner to river sediment sampling.Special care was taken to prevent loss of the fine particulates.
in the sediment.In addition, formalin was added to the sanitary pond sediment prior to shipping, to inhibit gas formation within the sample container.
4.3.6 Fish Fish sampling was performed during May and October, when the likelihood of obtaining anadromous species was high.Fish samples collected from the Columbia River (Station 30 in Figure 4-1)were indicator samples, while the fish collected on the Snake River (Stations 38 and 38A in Figure 4-2)were control samples.Four separate fish samples, consisting of an anadromous species and three other species generally considered edible or potentially edible (such as carp, catfish and whitefish), were collected at each location.Host of the fish were collected Fish, such as salmonids, which ascend rivers from the sea for breeding.4-5 through the use of electro-shock, but samples of the anadromous species were also collected from the Lyons Ferry Fish Hatchery on the Snake River.The fish were filleted to obtain one kilogram of edible flesh per sample.The fillets were placed in clean plastic bags and frozen until shipment to the analytical contractor.
Fish samples were shipped within 14 days of collection.
During 1992, the Site Certification Agreement was changed to require only annual fish sampling, unless a plant impact was observed.If that were to happen, semiannual sampling would be resumed.4.3.7 Milk 0~, Milk samples were collected monthly during January, February, March, October, November and December and semimonthly during the remaining six months when the cows were likely to be grazing.One gallon of raw milk was collected from each sampling location.The milk samples were chilled thoroughly and shipped to the analytical contractor within a day of collection.
Routine samples were collected from five indicator locations (Stations 36, 40, 59, 62 and 64)across the Columbia River in Franklin County, as shown in Figure 4-15.Milk samples were taken from Station 59 for only the last half of the year, since milk production resumed at this location in June.Samples were also collected at one indicator station (Station 9B)and one control location (Station 96)in the Sunnyside/Grandview area (in Figure 4-3).Station 9B in Grandview continued to serve as an indicator station in 1992 because a portion of the feed for the cows at that location is hay from the north Pasco area of Franklin County.That factor makes it unsuitable for use as a control location.~.4.3.8 Garden Produce Samples of local garden produce were collected monthly from April to September, when the produce was readily available.
When possible, three types of produce samples--a root crop, fruit and a leafy vegetable--were collected at each location.The indicator samples were collected from a region in a predominant downwind direction (Station 37 in Figure 4-2)where crops are irrigated with Columbia River water.The control samples were obtained from produce stands in the Sunnyside area (Station 9C in Figure 4-3), the direction least likely to be affected by plant effluents.
In addition, apples were collected in September from Station 91, the Rio.Vista Farms orchard, which is irrigated with Columbia River water and cherries were collected in June from Station 61, the Haymaker Farm.These produce samples were shipped to the analytical contractor within two days of collection.
 
====4.3.9 Vegetation====
Samples of vegetation growing in the storm drain pond bed were collected periodically during 1992.Cattails and grasses were the principal types of vegetation collected.
Approximately two kilograms of sample were collected each time.Care was taken to avoid including the roots or soil from around the roots in the samples.The vegetation samples were then shipped to the analytical contractor within two days of collection.
~'-6 4.3.10 Snow 1 Snow is not routinely sampled by the REHP.During 1992, however, snow samples were taken in order to gather information concerning tritium levels in the environment around Plant 2.Each sample consisted of fresh snow collected in a'plastic or teflon container placed outside during snowfalls or collected by shoveling all the snow, from ground level to the top, in a designated area.The volume of snow collected was sufficient to provide at least a one-liter water sample for analysis.The samples were shipped to the analytical contractor within two days of collection.
4.4 Anal tical Procedures The analytical procedures used for the 1992 REHP samples are described below.Teledyne Isotopes performed all routine analyses of REHP samples during 1992.4.4.1 Gross Beta Activity on Particulate Filters The particulate filters were counted in a gas-flow proportional counter after a delay of five or more days to allow for the radon-222 and radon-220 (thoron)daughter products to decay.An unused air particulate filter was counted as the blank with each weekly set of'ilters.
 
====4.4.2 Measurement====
of Gamma Emitters Milk and Water A 1-liter Harinelli beaker was filled with a representative aliquot of the sample.The sample was then counted for at least 1000 minutes (16.7 hours)with a shielded Ge(Li)detector.Foodstuff As much of the edible portion of the sample as possible was loaded int'o a tared Harinelli beaker and weighed.The sample was then counted for at least 1000 minutes (16.7 hours)with a shielded Ge(Li)detector.~Ve etation As much sample as possible is placed in a 1-liter Marinelli beaker and counted for approximately 16 hours with a shielded Ge(Li)detector.The sample is not dried prior to counting, so the results are given in terms of wet weight.Soils and Sediments A large quantity of the sample was dried at a temperature below 100'C.As much sample as possible was loaded into a tared 1-liter Harinelli beaker and weighed.The sample was then counted for at least 360 minutes (6 hours)with a shielded Ge(Li)detector.4-.7 Charcoal Cartrid es Air Iodine Charcoal filters were counted up to five at a time, with one positioned on the face of a Ge(Li)detector and up to four on the side of the Ge(Li)detector.Each Ge(Li)detector was calibrated for both positions.
The detection limit for iodine-131 on each charcoal cartridge was determined (assuming no positive iodine-131) uniquely from the volume of air which passed through it.In the event that iodine-131 would have been observed in the initial counting of a set, each charcoal cartridge in the set was then positioned separately on the face of the detector and counted.0 Air Particulate Filters Four air particulate filters for a quarterly composite for each field station were aligned one in front of another and then counted for at least 360 minutes (6 hours)with a shielded Ge(Li)detector.The shielded Ge(Li)detector was coupled to a mini-computer-based data acquisition system which performed pulse height analysis.A mini-computer software program defined peaks by certain changes in the slope of the spectrum.The program also compared the energy of each peak with a library of peaks for isotope identification and then performed the radioactivity calculation using the appropriate fractional gamma ray abundance, half-life, detector efficiency, and net counts in the peak region.,4.4.3 Gross Beta Activity in Water A one-liter aliquot of each sample was evaporated to a small volume and transferred to a stainless steel planchet.The sample was dried under heat lamps, cooled, then counted on an automatic beta proportional counter.The results were calculated using empirical self-absorption curves which enabled the correction of effective counting efficiency, based on the sample residue mass.4.4.4 Iodine-131 in Water~.Two liters of sample were first equilibrated with stable iodide carr ier.A batch treatment with anion exchange resin was used to remove iodine from the sample.The iodine was then stripped from the resin with sodium hypo-chlorite solution, reduced with hydroxylamine hydrochloride and extracted into carbon tetrachloride as free iodine.It was then back-extracted as iodide into sodium bisulfite solution and precipitated as palladium iodide.The precipitate was weighed for chemical yield and mounted on a nylon planchet for low level beta counting.The chemical yield was corrected by measuring the stable iodide content of the water with a specific iop electrode.
During 1992, this procedure was used only on intercomparison samples, since the doses calculated via ODCM methodology for the consumption of drinking water did not exceed 1 mrem per yea}(Table 4-1, footnote n).4.4.5 Tritium in Water During the first half of 1992, the tritium analyses were performed using gas counting techniques.
Approximately two milliliters of water were converted to hydrogen by passing the water, heated to its vapor state, over a granular zinc conversion column heated to 400'C.The hydrogen was loaded into a one-liter proportional detector and the volume was determined by recording the pressure.4-8 The proportional detector was passively shielded by lead and steel and an electronic, anti-coincidence system provided additional shielding.
from cosmic rays.From July to the end of the year, Supply System samples were analyzed for tritium.using liquid scintillation.
Liquid scintillation requires 10 milliliters of water mixed with 10 milliliters of liquid scintillation"cocktail".
The mixture is then counted in an automatic liquid scintillation detector.4.4e6 Strontium-89 and 90 in Water, Milk and Soil During 1992, strontium analyses were not required for any routine REMP water or milk samples.Strontium analysis was required for one routine soil sample (Station 23)which had cesium-137 levels ten times greater than those measured for Station 9A, the control location.It was also used for special and intercomparison water and sediment analyses.The techniques used to analyze for strontium in the various media are described below.Water Stable strontium carrier was added to one liter of sample and the volume was reduced by evaporation.
Strontium was precipitated as Sr(N03)~using fuming (90%)ni tri c ac i d.Milk Stable strontium carrier was added to one liter of sample.The sample was then evaporated and ashed in a muffle furnace.The ash was dissolved and strontium was precipitated as a phosphate.
It was then redissolved and strontium was precipitated as Sr(N03), using fuming (90%)nitric acid.Soil and Sediment The sample was first dried under heat lamps and a 10-gram aliquot was taken.Stable strontium carrier was added and the sample was leached in hydrochloric acid.The mixture was filtered.Phosphates were then precipitated, collected by filtration and dissolved in nitric acid.Strontium was precipitated as Sr(NO~)2 using fuming (90%)nitric acid.A barium chromate scavenge and an iron (ferric hydroxide) scavenge were then performed.
Stable yttrium carrier was added and the sample was allowed to stand for 5 days or more for yttrium ingrowth.Yttrium was then precipitated as hydroxide, dissolved and reprecipitated as oxalate.The yttrium oxalate was mounted on a nylon planchet and counted in a low-level beta counter to infer strontium-90 activity.Strontium-89 activity was determined by precipitating SrCO, from the sample after yttrium separation.
This precipitate was mounted on a nylon planchet and covered with an 80 mg/cm aluminum absorber for low-level beta counting.4.4.7 Iodine-131 in Mi 1 k Two liters of sample were first equilibrated with stable iodide carr ier.A batch treatment with anion exchange resin was used to remove iodine from the sample.The iodine was then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride and extracted into carbon tetrachloride as free iodine.It was then back-extracted as iodide into sodium bisulfite solution and precipitated as palladium iodide.The precipitate was weighed for chemical yield and mounted on a nylon planchet for low-level beta counting.The 4-9 chemical yield was corrected by measuring the stable iodide content of the milk with a specific ion electrode.
4.5 Data Anal sis Methods Since mid-1984, the results of the REMP analyses have been given as net results calculated from the gross or total counts determined for each radionuclide minus the background counts of the counting or detection instrument.
Consequently, for several sample types, the results range from negative to positive numbers.This manner of presenting environmental data prevents the bi as and loss of individual results inherent in the use of"less than" (<)values, where the"less than" numbers can have a variety of meanings, such as"less than the lower limit of detection (LLD)" or"less than the two sigma uncertainty." The net results for REMP samples are presented with an asterisk (*)in front, if the results are less than.the LLD.A listing of the LLDs determined for each analysis is provided in Table 5-2 as a reference when reviewing the sample results.Plots of the, sample results versus time are used to represent the results for analyses such as gross beta on air particulate filters, where the results are normally above the lower limits of detection.
In such cases, the indicator station results are plotted with the control station results for easy comparison.
Other data analysis techniques, such as frequency distributions, are also used to represent the data and to determine whether trends that could be attributed to Plant 2 operations are evident.Thermoluminescent dosimeter (TLD)data is presented in terms of the net mR/day.exposure rate.These results are determined from the total exposure (in mR)calculated for each TLD from its total thermoluminescent output minus the TLD background, minus any transit (or trip)exposure received during distribution and retrieval, and divided by the number of days the TLD was in the field.Circular plots, frequency distributions and graphs of TLD data by meteorological sector and distance from the plant are used to interpret trends in the results.TLD data summaries include the term"standard error," along with"standard deviation." The standard error, which is the estimate of the precision of the mean, is used for the means of quarterly and annual data.The standard deviation is used for the TLD data involving a single dosimeter result that has been determined from the four reader areas of the TLD.Both terms simply provide an indicator of the uncertainty associated with the results.Oo 4-10 TABLE 4-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM PLAN SAMPLE TYPE"'.AIRBORNE SAMPLE STATION+'UMBER SAMPLING AND COLLECTION FREQUENCY" TYPE AND FREQUENCY OF ANALYSIS Particulates and radioiodine 1, 4-9A 21, 23, 40, 48, and Continuous sampling;weekly (6/12)"'7 collection Particulate:

TABLE 4 ont.)Gamma isotopic means identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents of Plant 2.Soil samples are collected to satisfy the requirements of the Site Certification Agreement (SCA)for Plant 2.The SCA requires that soil samples be collected at five air sampling locations.
Strontium-90 analysis shall be performed on any indicator soil sample having cesium results greater than ten times the results for the control location.During 1992, strontium 90 analysis was performed on the Station 23 soil.TLD refers to thermoluminescent dosimeter.
For purposes of the REHP, a TLD is a phosphor card (31.75mm x 44.75mm x 0.4mm)with eight individual read-out areas (four main dosimeter areas and four back-uq dosimeter areas)in each badge case.TLDs used in the RENP meet the requirements of Regulator Guide 4.13 and ANSI N545-1975', except for specified energy-dependence response.Correlation factors are available for energy ranges with response outside of specified tolerances.
TLD Stations 71-86 are special interest stations and are not included among the 34 routine TLD stations required by the Plant Technical Specification Table 3.12-1.Their alternate designations are 1S-16S.Station 61, a special interest location, was discontinued in June.The SCA requires that 25 or more TLD stations are located within a 10-mile radius of the plant.Pressurized ion chambers (PICs)are not required as part of the routine monitoring program, but they are required by the SCA to be maintained as a supplemental or backup system.PICs were used routinely at various locations during 1992 to provide supplemental information.
The term"river/drinking water," instead of"surface/drinking water", is used throughout this report because the surface water is taken from the Columbia River.Station 26, Plant 2 makeup water intake from the Columbia River is both an upstream surface, or river, water sample and the drinking water control sample location.Station 28 (300 Area)and Station 29 samples are drinking water samples.The Station 27 sample, which is drawn from the plant discharge line, is taken in place of a"downstream" water sample near but beyond the mixing zone.It reflects the radioactivity present in the plant discharge prior to any river dilution.The SCA requires two drinking water locations downstream from the plant discharge and requires sampling from the plant intake and discharge water.Station 101, the storm drain pond,'and Station 102, the Sanitary Waste Treatment Facility, are represented individually because they are unique sampling locations requiring special attention.
Composite (integrated grab)samples are collected with equipment which collects an aliquot at time intervals that are short relative to the compositing period.When the gross beta activity in drinking water exceeds 8 pCi/liter, a strontium-90 analysis is performed.
TABLE 4-1 (Cont.)When the dose calculated vi a ODCN methodology for consumption of water exceeds I mrem per year, iodine-13 1 analyses are performed on the drinking water sampl es.The SCA requires sampling from wells used for fire protection and as backup drinking water sources.The SCA requires sediment sample collection upstream and downstream of the plant discharge.
Milk samples will be obtained from farms or individual milk animals which are located in the most prevalent wind directions from Plant 2.Routine milk samples are collected in areas of high dose potential instead of within 5 kilometers, due to the locations of milk animals.The SCA requires at least three-milk locations within the 10-mile r'adius of the plant and one in a control location.Station 96 is the control station for milk samples because it was determined that the cows at Station 9B in Sunnyside were given feed grown in the Franklin County area across the Columbia River from Plant 2.Station 59 was reestablished as a milk location in June 1992.If cesium-134 or cesium-137 is measured in an individual milk sample in excess of 30 pCi/1, then the strontium-90 analysis will be performed.
There are no commercially important species in the Hanford Reach of the Columbia River.Host recreationally important species in the area are anadromous'(primarily salmonids), which ascend rivers from the sea for breeding.Four fish specimen will normally be collected by electroshock technique in the vicinity of the plant discharge (Station 30)and from the Snake River (Station 38).If electroshocking produces insufficient anadromous fish samples from the Snake River, samples may be obtained from the fish trap at Ice Harbor Dam, Lyons Ferry Fish Hatchery, or other similar facility (Station 38A).If insufficient anadromous fish samples are produced through electroshocking on the Columbia River, samples may be obtained at the Ringold Fish Hatchery (Station 39).The SCA requirement for semiannual fish sampling was changed to annual sampling.This change will be implemented in 1993.Garden produce will routinely be obtained from farms or gardens using Columbia River water for irrigation.
One sample of a root crop, leafy vegetable, and a fruit is collected each sample period;if available.
The variety of the produce obtained will be dependent on seasonal availability.
Station 61 is the Haymaker Farm, which has a large cherry orchard.A cherry sample is collected in June each year.Station 91 is an apple orchard irrigated by the Columbia River.'he apple crop from Station 91 is sampled annually.0 0 TABLE 4-2 REMP SAMPLE LOCATIONS BY SECTOR SECTOR" STATION~b~

Table 5-1 presents the means and ranges of the 1992 results for each type of sample collected.
The means and ranges of the preoperational and the previous operational data from 1984 to 1991 are also included in the table for comparison.
The data for the preoperational period and the first six months of 1984 included"less than" (<)designations for results below the actual LLD, the contractual LLD or the two sigma error, depending upon the convention employed by the analytical contractor.
Consequently, the data averages using"less than" values are biased high.The use of the"less than" values was discontinued in mid 1984.Since then, REHP data have been reported as net results (total)results minus the detector counting background).
Since the primary focus of the REHP is to determine whether Plant 2 operations have impacted the environment, the 1992 results are compared in this report to the results during the preoperational period and the results obtained during the previous years of Plant 2 operation.
They are compared, as well, to state and federal regulatory limits.Because of the use of"less than" values, rather than net results, during the preoperational period and during the first year of operation and because of the impact of the 1986 Chernobyl accident on environmental radiation levels, the interpretation of the 1992 measurements relative to previous.measurements must be done carefully.
Some of the parameters considered in the evaluations discussed in this report are the means, ranges and standard deviations or standard errors of the results.Comparative plots and frequency distributions of the data are some of the tools that have been employed in the interpretation of the 1992 REMP data.The 1992 analytical results for the REMP sampling locations established since the preoperational period are very similar to the results reported for previous years.The 1992 annual and quarterly TLD results were also very much like those observed previously.
No significant trends indicating an environmental impact or unexpected change in the environmental concentrations or exposure rates at these stations was observed.At two of the special interest locations, Station 101 and Station 102, there were significant changes observed.At Station 101, the storm drain, there has been some environmental impact, the most significant of which is the contamination of the sediment and soil in and beneath the pond.The changes observed at Station 102, the Sanitary Waste Treatment Facility, were very low level and were considered to have no impact on the environment.
At Station 118, the containerized storage area, radionuclide concentrations were at normal background levels.The LLDs generally determined by Teledyne Isotopes for each analysis performed and each radionuclide of interest are listed in Table 5-2.Presented alongside the Teledyne LLDs are the LLDs required by the NRC Branch Technical Position (BTP)."'he LLDs determined for analyses at Teledyne Isotopes have met the NRC requirements in all cases.5-1 A summary of the 1992 results that were detectable is presented in Table 5-3.If a particular radionuclide of interest was not detected in the 1992 samples the term"LLD" is noted in the data mean and range columns.5.1 Direct Radiation Summaries of the environmental radiation exposure rates, determined by thermoluminescent dosimeters (TLDs)are presented in Tables 5-4 and 5-5.The individual quarterly and annual results for each TLD station are given in Tables A-1.1 and A-1.2 of Appendix A.Figures 5-1 and 5-2 show the mean quarterly results for near-plant and remote TLD locations for the preoperational period, 1984-1991 and 1992.Figures 5-3 and 5-4 show the annual TLD results for near-plant and remote locations for the same periods.The quarterly and annual results for the control location (Station 9A)show similar fluctuations over time as the indicator locations and the relationships between the different locations remain very consistent over the three periods.Figure 5-5 presents a circular plot of the mean 1992 quarterly TLD results for each of the sixteen meteorological sectors, compared to the sector means for.the preoperational and previous operational periods.The relationship of the mean 1992 results to the results for the preoperational and previous operational periods is very similar for each sector.This indicates that there were no significant directional effects observed in the 1992 TLD results.The apparent increase in the mean 1992 TLD results over the means of the preoperational and previous operational periods is due to the effect of averaging only the four quarters of 1992 data, versus averaging numerous quarters for the other two sets of results.The differences between the data sets are generally within 10%, which is within the range of variation normally expected for TLD systems.The annual TLD results for each sector also follow the same pattern as the mean quarterly results, except they are approximately 5%lower.Station 46 in the Wahluke Reserve remained the location with the highest mean exposure rate, 0.31 mR/day.This is the same mean exposure rate determined for that station for 1989, 1990, and 1991.Since the preoperational measurement phase, the results for this location have exceeded the results for all other locations.
Variations in the ambient background due to differences in the soil and underlying rock composition account for such local differences in the TLD results.A comparison of the 1992 annual and mean quarterly TLD results is presented in Table 5-6.The 1992 annual TLD results are generally 5-10%lower than the mean quarterly results because of the signal fading characteristics of calcium sulfate (CaSo4).This difference is not significant, in light of the variability commonly observed in TLD results.In most cases, the annual result is within the uncertainty associated with the quarterly TLD results.Frequency distribution plots of the 1992 quarterly TLD results are presented in Figure 5-6.The plots are very similar from quarter to quarter, with 0.26 mR/day being the most frequent result and with the Station 46 results being upscale and separate from the main distribution.
The frequency distributions for the quarterly preoperational, previous operational and 1992 TLD results are compared in Figure 5-7.The three distributions agree well.0 5-2 The 1992 annual TLD results are also consistent with results observed for the past monitoring periods.This is evident in the comparison of the current results with preoperational and previous operational results presented in Table 5-5.The above comparisons of 1992 TLD results to preoperational and previous operational data and the analysis of results by meteorological sector and distance from the plant demonstrate that Plant 2 operations have not impacted the direct radiation levels in the environment around the plant.5.2 Airborne Particulate Iodine 1 The results of the 1992 gross beta in air analyses are presented in Tables A-2.1 and A-2.2 of Appendix A.The 1992 mean weekly results of all indicator stations are plotted in Figure 5-8.The gross beta in air results for 1992 were within the ranges observed during the preoperational period and during previous operational periods, as shown in Table 5-1.In Figure 5-9 the similarity between results from near-plant locations and those from remote locations can be seen.The control location (Station 9A)results follow a very similar pattern to the remote and near-plant, indicator locations.
As observed previously, gross beta levels increased during periods of inversion occurring in the fall and winter months.In fact, the gross beta results plotted over a period of several years show a cyclic pattern of fall and winter increases.
The=increase, which was evident in the results of all the air sampling locations is due to an increase in radon and radon daughter concentrations during the inversions.
The quarterly gamma analyses of the particulate filter composites indicated only the presence of two naturally-occurring radionuclides, beryllium-7 and potassium-40, at levels above detection limits at indicator locations and the control location.The results of the gamma analysis of particulate filter composites are presented in Table A-3.1 and A-3.2 of Appendix A.The results of the gamma analyses of charcoal cartridges for iodine-131 are presented in Table A-4.1.All iodine-131 in air results for 1992 were less than the 0.01 pCi/cubic meter LLD.No evidence of any impact of plant operations on the environment was apparent in the particulate filter and charcoal cartridge results for 1992.5.3 Water The gross beta in river/drinking (including intake)and discharge water results are given in Tables A-5.1 and A-5.2 of Appendix A.All river/drinking water results were within the ranges normally observed and less than 8 pCi/liter, the level at which a strontium analysis is performed to verify compliance with the Washington State drinking water standard for strontium-90
.The 1992 gross beta concentrations in river/drinking water, relative to the state annual average concentration limit"", are presented in Figure 5-10.The mean gross beta results in river/drinking water and discharge water, for 1984 to 1992 are compared to the state annual average concentration limit (8 pCi/liter) and the DOH investigation level (75 pCi/liter), respectively, in Figure 5-11.The current average results compare well to the averages from previous periods.Strontium-90 is assumed to account for the gross beta result.5-3 The mean gross beta levels in the discharge water were slightly lower in 1991 and 1992 than the previous levels observed during the period of 1984-1990, as shown in Figure 5-11.This lower gross beta level resulted from the current mode of plant operations using less concentrated circulating water (lower cycles of concentration).
The gross beta levels in the discharge sample reflect the concentrations of naturally-occurring radionuclides, principally potassium-40, and any radionuclides from upstream sources of past Hanford activities present in the makeup water, in addition to radionuclides from Plant 2 discharges.
The discharge sample results are representative of the radioactivity present in plant discharges before any mixing with river water occurs.Therefore, the sample is not indicative of the actual radionuclide concentrations in the river water downstream from Plant 2.Flow-proportional composite sampling from the discharge line was considered to be the most feasible option for meeting the ODCN requirement for sampling from the river near the downstream edge of the mixing zone.However, careful interpretation of the results from this sampling point is necessary, since they do not represent true environmental samples.The tritium results for river/drinking water, discharge water and groundwater are presented in Tables A-6.1 and A-6.2 of Appendix A.The tritium levels in the river/drinking water were all below the LLD, except two results which were at the detection level.The mean results for 1992 are compared to previous periods in Figure 5-12.All the tritium results for the quarterly groundwater samples were below the LLD.Tritium levels in the discharge water were higher than the levels observed for the river/drinking water samples because of plant releases and because discharge water samples are taken prior to the water reaching the river and becoming diluted.As shown in Figure 5-13, the mean result was much higher than the mean levels observed for 1991 and the 1984-1990 period.The tritium concentration in the discharge water ranged from 1800 to 5400 pCi/liter, which is still low, when compared to the NRC reporting level of 20,000 pCi/liter for a quarterly average concentration in.dch"ki" d Cobalt-60, zinc-65 and cesium-137 were detected in some discharge samples during and following the plant outage.The detectable cobalt-60 results ranged from 6.6 to 20.5 pCi/liter, the zinc-65 results ranged from 14.3 to 27.9 pCi/liter, and the cesium-137 results ranged from 5.1 to 9.9 pCi/liter.
Although above detection levels, these results were low and did not exceed any reporting levels.5.4 Soil Gamma spectrometry was performed on five soil samples collected in Hay.The detectable cesium-137 levels in the samples ranged from 35.9 pci/kilogram to 489.0 pCi/kilogram.
As shown in Table 5-1, the cesium-137 levels in the soil samples were well within the range observed during preoperational and previous operational sampling.However, the cesium-137 levels measured in one of the soil samples, Station 23, exceeded the cesium-137 measured in the control sample, Station 9A, by more than a factor of 10.A strontium analysis was, therefore, performed on that sample, as required by the Site Certification Agreement.
The strontium concentration in the sample was below the detection level and below the range previously observed, as shown in Table 5-1.Aside from cesium-137, the only radionuclides detected in the samples were potassium-40, radium-226 and thorium-228.
These are part of the natural radioactivity typically found in soils.
The gamma spectrometry results for the soil samples are given in Tables A-8.1 and A-8.2 in Appendix A.No indication of impact of Plant 2 operations on the environment was evident in these results.5.5 River Sediment The results of gamma spectrometry of river sediment are presented in Tables A-9.1 and A-9.2 in Appendix A.Aside from the naturally-occurring radionuclides (potassium-40, radium-226 and thorium-228), only cesium-137 was detected downstream of the plant (Station 34).Cesium-137 was also detected in the control location (Station 33)sample.The cesium-137 concentrations upstream from the plant discharge point were 64.0 and 98.7 pCi/kilogram; the concentrations downstream from the discharge point were 198.0 and 221.0 pCi/kilogram.
These are consistent with the concentrations observed previously, as shown in Figure 5-14.Cesium-137 has been detected in preoperational samples and in samples taken since plant operation began.It has also been previously identified as a component of the Columbia River sediment originating from the operation of the old Hanford Reservation reactors."" 5.6 Fish The gamma spectrometry results of fish samples collected in the vicinity of the.Plant 2 discharge and at the control location on the Snake River are presented in Tables A-10.1 and A-10.2 of Appendix A.All results were below detection limits, except for potassium-40, a naturally-occurring radionuclide, and cesium-137.
The detectable cesium-137 levels for the fish taken from the Columbia River were low and within the range observed during the preoperational and previous operational periods.5.7 Milk All the results of iodine-131 analyses of milk samples collected during 1992 were less than detection limits.The routine iodine-131 in milk results are listed in Tables A-11.1 and A-11.2 of Appendix A.The gamma spectrometry results for the same milk samples are listed in Tables A-12.1 and A-12.2.All results for the indicator and control locations were less than the detection limits, except for potassium-40, which is naturally-occurring.
5.8 Garden Produce The gamma isotopic analysis results for all root, fruit and leafy vegetables were below detection limits.The results of all produce samples, including the apples collected from Station 91 and the cherries collected from Station 61, are listed in Tables A-13.1 through A-15.2 of Appendix A.5.9 S eci al Interest Sam les Three special'interest sampling locations were incorporated into the REMP during 1992.Discussions of the results from each of the three locations are given in the following sections.None of these locations, the storm drain, the Sanitary Waste Treatment Facility (SWTF), and the containerized storage area, were a part of the routine sampling 5-5 program for the,REHP until 1992.Until incorporated into the REHP, the sediment samples collected during previous years at the storm drain and SWTF were analyzed in the Support Services radiochemical laboratory in-house.The storm drain and SWTF sediment samples were analyzed wet, so the results were in terms of wet weight, instead of the dry weight concentrations determined by Teledyne.So direct-comparison of the wet sample results with the dried sample results is difficult since the percent solids can vary from sample to sample.This report includes only the samples collected during 1992.The data for containerized storage area, Station 118, consists of twenty-nine large metal storage containers holding the low pressure turbine rotor parts removed from the plant during the 1992 maintenance outage.'oil samples and ionization chamber readings were taken at Station 118.5.9.1 Storm Drain Pond Station 101 The storm drain pond is the drain field formed by the liquid discharges leaving Plant-2 via the storm drain pipe.The storm drain pond is located approximately 1500 feet east northeast of Plant-2, within the Plant-2 restricted area.The storm drain receives water from several sources, including building roof drains, the Service Building floor drain sump, the Diesel Generator Building floor dr ains, air handling unit drains, backwash effluent from gravity and carbon filters in the Service Buil'ding, and Turbine Building nonradioactive floor drains., The water released through the 18-inch diameter storm drain pipe flows into a 300-foot long earthen channel and then into the pond, which is approximately 100 feet in diameter.The pond is a shallow, unlined percolation/evaporation basin.Although not a part of the REHP sampling plan until early 1992, the storm drain sediment and water were periodically sampled by the REHP in the past.Periodically, cesium-137, cesium-134, cobalt-60 and zinc-65 were observed in the sediment and investigated, but the source(s)of the activity was never resolved.Then in February 1992, the storm drain became a part of the REMP sampling plan and the water, sediment, soil and vegetation samples collected there were sent to Teledyne~Isotopes for analysis.On April 29 and May 13, 1992, the REHP staff observed milky and red-colored water coming from the storm drain.A water sample collected at the storm drain outfall on April 29 contained detectable iodine-131'(12.6 pCi/liter).
A water sample collected on Hay 13 also contained detectable iodine-131 (21.1 pCi/liter), as well as cobalt-60 (124.7 pCi/liter), antimony-125 (20.8 pCi/liter), and cerium-141 (707 pCi/liter).
The tritium concentration measured in the water was 270,000 pCi/liter.
Problem Evaluation Request (PER)292-0531 was submitted to plant management on Hay 22.Because the iodine-131 and tritium levels in these samples resulted in the quarterly average concentrations for tritium and iodine-131 exceeding the NRC reporting levels, a Radiological Environmental Monitoring Program special report was submitted to the NRC on July 30, 1992.The sediment and water sampling frequency at the storm drain increased to daily, in order to characterize the extent of the release in April and May and to track the radioactivity levels.The radionuclide concentrations in the storm drain water on Hay 13 are compared to the NRC Reporting Levels, given in terms of quarterly averages, and the Washington State DOH investigation levels, given in terms of a single result, in Table 5-7.In order to characterize the impact of the radioactivity released on the storm drain sediment, a special set of surface sediment, samples'ere taken at six locations in 0'5-6 the channel and pond on Hay 22.Significant concentrations of cobalt-60, zinc-65, cesium-137, cesium-134, cerium-141 and manganese-54 were found at these locations.
A listing of the Hay 22 sample results and the results for sediment samples taken again at these locations on November 19 are given in Table 5-8.Although elevated levels of cobalt-60 and zinc-65 had periodically been observed in the past in the storm drain sediment, the levels were less than the concentrations following the Hay 13 incident.On July 9, core samples were taken at three locations to a depth of approximately five feet.The results of these core samples are presented in Table B-6.1 in Appendix B.Cobalt-60 was the most significant radionuclide found in these samples.The highest concentration of cobalt-60 was 2,410 pCi/kilogram, which was found at a depth of three feet at the storm drain pipe outfall.Samples at the other locations and depths contained much lower concentrations and some low concentrations of the other r adionuclides observed in surface samples.Cattail samples taken at the storm drain outfall on June 17 and September 16 showed detectable levels of cobalt-60, zinc-65, cesium-134, cesium-137, and manganese-54 (Tables 5-9 and B-8.1).An earlier cattail sample taken on Hay 22 and a grass sample taken on Harch 19 did not contain detectable concentrations of these radionuclides.
The root cause analysis resulting from PER 292-0531 concluded that the event occurred as a result of a transfer of water from a radioactive Turbine Building sump to a nonradioactive Turbine Building sump which was discharged to the storm drain.Corrective actions included evaluating potential leak paths from radioactive drain systems to nonradioactive systems, evaluating the sensitivity of monitoring equipment used on the floor drain sumps to determine whether it can be improved significantly, reporting the results of core samples used to characterize the storm drain radioactivity and exploring alternate methods of treating the high conductivity water historically discharged via the storm drain.In October an inspection by the NRC resulted in two notices of violation concerning the storm drain: (1)The Supply System disposed of radioactive liquid from a Turbine Building sump by discharge to the storm drain, a method not authorized by 10CFR20.301", (2)The Supply System had not maintained in the updated Final Safety Analysis Report (UFSAR)a description of the change to the facility resulting from the demonstration that nonradioactive Turbine Building sumps are now used as radioactive sumps and no written safety evaluation of this change was performed.
Following the Hay incident, tritium levels at the storm drain remained near the lower limit of detection until mid-June when a gradual.increase was observed.By September the tritium levels were approaching 30,000 pCi/liter, the NRC reporting level for a quarterly average concentration.
On November 6 PER 292-1255 was written to inform plant management that tritium levels at the storm drain continued to be significant.
Response to this PER included isolation of in-plant sources to the storm drain and the processing of water in the Turbine Building sumps through radwaste.On November 11, PER 292-1274 was submitted to alert plant management that the total radioactivity, particularly cobalt-60, in the storm drain sediment may exceed the 10CFR20 Appendix C values for designating a radioactive materials area.Response to this PER,included posting the storm drain area as a radioactive materials area, 5-7 making provisions for fencing the area and upgrading security surveillance of the area to prevent unauthorized access.Finally, because tritium levels both in the pond and at the outfall continued to be elevated, despite the isolation of the sources of input, PER 292-1339 was submitted on November 24.Response to this PER included performing a thorough walkdown to identify additional sources of input to the storm drain and continuing to isolate sources of contamination.
On November 25, a portable composite sampler was installed at the storm drain outfall.This sampler collects a 35-milliliter aliquot hourly and combines these into a daily composite.
Work will continue into 1993 to upgrade this sampling system to permit flow-proportional sampling.Snow samples were taken on December 18 at a location southwest of the cooling towers, in order to determine the tritium in the environment around the plant.The fresh snowfall at that location contained 410-430 pCi/liter (of water), which is above the detection level of 100 pCi/l.On the same day, a sample was taken from the water in cooling tower 2B and analyzed for tritium.The tritium concentration in that water was 460 pCi/liter.
As shown in Figure 5-15 and Table B-3.1 in Appendix B, the tritium levels continued to fluctuate from near detection level (100 pCi/liter) to 30,000 or 40,000 pCi/liter.
Then on December 31, the tritium concentration rose to 110,000 pCi/liter.
Investigation into the sources of the tritium revealed that meteorological conditions such as the cold temperatures and the wind direction were apparently causing the Turbine Building gaseous effluents containing tritium to condense on the adjacent building roofs and enter the storm drain.**An evaluation of the tritium results for the fourth quarter of 1992 indicated that the quarterly average tritium concentration was about 16,000 pCi/liter, which is well below the 30,000 pCi/liter average concentration requiring an NRC special report.5.9.2 Sanitar Waste Treatment Facilit Station 102 The Sanitary Waste Treatment Facility (SWTF), located approximately 0.3 mile south of Plant 2 processes the sanitary waste from Plant 2, the WNP-1 and WNP-4 sites and the Plant Support Facility (PSF).In 1991 a pipeline was installed from the Department of Energy's Fast Flux Test Facility (FFTF)to the Supply System SWTF to permit sanitary waste from FFTF to be processed there at some point in the future.The arrangements for this processing of FFTF wastes were never finalized, however.A valve was to have been installed at the FFTF end of the pipe to prevent the flow of wastes from FFTF.In November of 1991 EFSEC approved Resolution No.259"", which approved the introduction of FFTF wastes into the Supply System SWTF and outlined discharge standards and monitoring requirements.
Until April 1992, the SWTF sediment was sampled semiannually and analyzed in the Support Services radiation laboratory and the radionuclide concentrations were given in terms of wet weight.In April 1992, the sampling routine to satisfy Resolution No.259 was begun and the SWTF became a part of the REHP sampling plan.Water samples were taken at least monthly and sediment samples, which were not required by the resolution, were taken from the northern settling pond on a quarterly basis.Both the sediment and water~t*Tritium concentrations in water on the Service Building roof on December 25 and 26, for example, were 2,470,000 and 2,950,000 pCi/liter.

-samples were sent to Teledyne Isotopes for analysis, like all the other routine REAP samples.No detectable gamma activity was found in the April 1992 sediment sample or in the monthly water samples.In the July sediment sample however, cobalt-60 was detected in the sediment, so, the sampling frequency increased to monthly.In the next sediment sample taken August 12, both cobalt-60 and cesium-137 were detectable and present at concentrations far above levels that had been previously observed.Additional sampling was performed in September and October to determine the radionuclide levels in both stabilization/settling ponds.Water samples were also taken from both ponds and analyzed for tritium, as well as gamma emitters.When the results were received in late October, Problem Evaluation Request (PER)292-1206 was written, because the sediment in the north stabilization pond showed elevated levels of cobalt-60 (245-728 pCi/kilogram) and cesium-137 (169-248 pCi/kilogram) and the tritium concentrations (1400 and 1000 pCi/liter) in'he two ponds were at and above the state investigations level of 1000 pCi/liter.
The Washington State Department of Health (DOH)and the Nuclear Regulatory Commission (NRC)were notified of the results.Water samples taken from the aeration ponds, which had not received sanitary waste for several years did not contain detectable tritium or gamma emitters.Samples of water found in the pipeline on October 30 from FFTF, however contained 6,400 pCi/liter of tritium.On November 6, water and sludge samples were taken from the FFTF septic tank and ,sediment was taken from the drain field into which the FFTF septic tank had overflowed for several years.In addition, the pipeline leading from the septic tank to the SWTF was observed to have no valve to prevent FFTF wastes from entering the pipe.Tritium levels found in the septic tank water were 6,200 to 6,700 pCi/liter.
The septic tank sludge sample contained 400 pCi/kilogram of cobalt-60.
The soil taken from the drain field contained 359 pCi/kilogram of cobalt-60 and 284 pCi/kilogram of cesium-137.
Additional sampling at various SWTF locations indicated that water containing elevated tritium levels had been flowing into the facility since at least Hay 1992.Water samples taken before that were not available for reanalysis so the exact period of time the FFTF waste had been entering the SWTF could not be determined.
Samples of soil/sludge taken from a percolation bed, the dosing pond and the nearby lift station overflow basin showed no detectable gamma activity, indicating that the present gamma activity found in the stabilization pond sediment had not been present long enough to impact the levels of radioactivity.
in the beds to which settling pond discharges are made.The root cause analysis report concerning this incident concluded that the radioactivity found in the stabilization ponds most likely originated at the FFTF and that the"failure to perform detailed testing of the FFTF sewage effluent prior to entering into an agreement to install the pipeline between FFTF and the SWTF was a basic reason for the incident to occur." To prevent recurrence, a concrete plug was installed in the pipeline from FFTF.The results of all the samples taken at the SWTF during 1992 are given in Appendix B.Graphs of the sediment concentrations of cesium-137 and cobalt-60 from 1987 through 1992 are presented in Figure 5-16.A drawing of the facility showing the sample locations and the most significant analytical results from the investigation into the detectable sediment and water radioactivity is presented in Figure 5-17.1992 tritium concentrations in the headworks and the north stabilization pond are presented in Figure 5-18.5-9 O.5.9.3 Containerized Stora e Area Station 118 Soil samples taken at Station 118 before and after storage of the low pressure turbine rotor parts contained no detectable radioactivity except that from naturally-occurring radionuclides, such as potassium-40 and radium-226.
In Nay, a small amount of water leaked from the storage container at location N at Station 118.The soil sample taken at the location contained no detectable radioactivity.
All the soil results for Station 118 are contained in Table B 19.1 and B 19.2 in Appendix B.5-10 TABLE 5-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAH COMPARATIVE

The adequacy of their quality assurance program is also assessed during the audits.Intercomparison programs, which involve the comparison of Supply System analytical results for samples containing known concentrations of various radionuclides with the known values and with the results reported by other monitoring programs, are also a major component of the quality assurance activities of the REHP.The program participates in the Environmental Protection Agency (EPA)and Environmental Measurements Laboratory (EML)intercomparison programs.It also participates in local and regional intercomparison studies.The following sections summarize the quality assurance and quality control aspects of the TLD and analytical components of the REHP.6.1 ualit Control For the Su l S stem Environmental TLD Pro ram The guality Control Program for the environmental TLD preparation, processing and evaluation is described in Figures 6-1 and 6-2.gA dosimeters, which are annealed just prior to being given a known exposure to 100 mR of cesium-137 gamma radiation and processed among the field dosimeters, serve as indicators that the readout, calibration and evaluation of the field dosimeters were properly performed.
The number of gA dosimeters used during each processing is generally 10%of the number of field dosimeters.
Since 1987 the same gA dosimeters have been used repeatedly throughout the year in order to track their sensitivity and to provide consistency from run to run.If the mean gA dosimeter results are greater than+5%(or 5 mR)of the given exposure, an investigation into the source of the discrepancy is initiated.
Evaluation of the 1992 gA dosimeter results indicated only small biases for the four quarters.Control dosimeters (trip controls)are used for each set of field dosimeters to monitor the contribution of the exposure received by the field TLDs while in transit.The radiation background in the storage area is also monitored by a separate set of control dosimeters (building controls).
If the trip control results are significantly greater than the building control results, the difference between the two is subtracted from the field dosimeters.
Spiked dosimeters, which are exposed to known levels of radiation below the 100 mR given to the gA dosimeters, were processed with the field dosimeters during each run to verify the accuracy of the environmental TLD evaluations.
The results of these audit dosimeters processed during 1992 are presented in Table 6-1.All results were well within a5%of the given exposure.6-1 During each environmental TLD processing, individual calibration factors are determined for each TLD by exposing the TLDs to 100 mR from an encapsulated cesium-137 source.The calibration exposure is determined from the exposure duration and the assessed source strength at 55 centimeters.
As a quality control check for each calibration exposure, an HIST-traceable ionization chamber is also used to determine the calibration exposure.If the ionization chamber measurement does not agree with the calibration exposure to within+5%of the calculated value, an investigation is performed into the discrepancy and the TLD calibration is repeated, if necessary.
6.2 ualit Control For the Anal tical Pro ram guality control for the analytical program involves two components:
the quality control activities performed by the Supply System and the quality control program of the analytical contractor, Teledyne Isotopes.Both of these components are described in the following sections.6.2.1 Supply System guality Control Activities The Supply System has participated in the U.S.Department of Energy Environmental Heasurements Laboratory (EHL)guality Assessment Program since 1987.The Supply System results for the samples sent out in Harch and September of 1992 are listed on Table 6-2.The Teledyne cesium-137 results showed the slight high bias (20-30%)in some media that has been evident in previous years.In general, however, the Teledyne results agreed with the EHL values.In addition to participating in the EHL Intercomparison Program, the Supply System participates in the Environmental Radiation guality Assurance Task Force of the Pacific Northwest (gATF)intercomparison program.During October 1992 three types of samples, groundwater from the Hanford Site, sediment from Bull Run Lake in Oregon and an EPA reference water sample, were distributed to participants.
The Supply System results for the gATF samples are given in Table 6-3 along with those for the other participants.
Duplicate samples were also submitted to Teledyne for analysis during 1992.These duplicates consisted of two sets of milk samples and one set of air filters from EHL.The milk duplicates were marked Station 37 and were submitted for analysis at the same time as the milk samples from Station 36.6.2.2 Teledyne Isotopes guality Control Program The goal of the quality control program at Teledyne Isotopes is to produce analytical results which are accurate, precise and supported by adequate documentation.
The program is based on the requirements of IOCFR50, Appendix B, Regulatory Guide 4.15 and the program, as described in Teledyne's equality Assurance Hanual IWL-0032-395 and guality Control Hanual IWL-0032-365.
All measuring equipment is calibrated for efficiency at least annually using standard reference material traceable to the National Institute of Standards and Technology (NIST).For alpha and beta counting, check sources are prepared and counted every week day except holidays.Control charts are maintained with 0 three-sigma limits specified.
Backgrounds are usually measured at least once per week.6-2 The efficiency of the gamma spectrometers is calibrated annually with a NIST traceable standard reference material selected to cover the energy range of the nuclides to be monitored and to include all of the geometries measured.Backgrounds are determined every other week and check sources are counted weekly.The energy resolution and efficiency are plotted at two energy levels (125.1 and 1274.4 kev)on charts and held within three-sigma control limits.The efficiency of the tritium gas counters was determined every month by counting a NIST traceable standard which had been diluted in a known amount of distilled water so that the activity level loaded into the counter is sufficient to provide good counting statistics but not so active as to contaminate the counter.If the efficiency measurement does not agree within two standard deviations of the average of the previous six measurements, corrective action is taken.The background of each counter is measured after each sample measurement.
A control chart is maintained for the background measurements as a stability check.This procedure is described in PRO-052-50"Calibration of Gas Counters for Tritium Analysis".
During the month of August the tritium gas counters were removed from service.The Supply System then approved use of liquid scintillation method of tritium analysis.Included in the tables for the Teledyne gA blanks and spikes is data for tritium analysis by liquid scintillation counting.Control of sample identity is maintained by the assignment of a unique five-digit number which is maintained throughout the sample's history from sample receipt, log-in number assignment and designation of analysis to reporting the final analytical result.'esides ensuring sample accountability, Teledyne procedures also ensure the maintenance of sample integrity by controlling sample storage and taking steps to prevent contamination of samples.Results are reviewed for reasonableness before being entered into the data system.Any results which are suspect, i.e., which are higher or lower than results in the past, are returned to the laboratory for recount.If a longer count, decay check, recount on another system or recalculation does not give acceptable results based on experience, a new aliquot is analyzed.The complete information about the sample is contained on the worksheets accompanying the sample results.No deviations from written procedures occurred during 1992.Summaries of the results of internal blanks and spiked samples used for quality control are presented in Tables 6-5 and 6-6.A summary of the EPA cross-check sample results is presented in Table C-I of Appendix C.Iodine-131 Cartrid es One blank charcoal cartridge was analyzed on a weekly basis with each set of cartridges, for a total of fifty-three blanks.The average result was 6.4+7.9E-Ol pCi per cartridge.
This was calculated without considering detection limits.Gross-Beta
-Filters One blank filter was measured with each set of filters analyzed.Fifty-three blanks were counted.The average activity in total pCi was 9.3+1.8E-Ol, which indicated a relatively stable background for the filters, including the background of the gross beta proportional counters.6-3 I-131-Mi1 k 0 A blank milk was analyzed with each group of samples analyzed.The results showed that there was no contamination in the laboratory or counting area.The measurements of the blank samples (Table 6-5)indicated that ther e was no bias on the low background counters.The average activity for twenty samples in 1992 was 2.615.3E-Ol pCi/liter.
This was calculated from quality control samples, without considering detection limits.A total of fifty-three in-house blank milk samples were processed throughout 1992.The average result was 3.915.1 E-02 pCi/liter.
Sr-90-Milk and Mater~'lank water samples were analyzed on a weekly basis.The average result of fifty-three blank water samples was 1.522.2E-Ol pCi/liter.
Fifty-three spiked water samples were analyzed.The average result was 3.710.2E+Ol pCi/liter, compared with a spike level of 4.010.6E<01 pCi/liter.
A total of twenty-three milk samples were spiked to a level of 4.0+0.6E+Ol pCi/liter.
The average activity determined for the spikes was 3.6t0.4E+Ol pCi/liter.
These results were within the limits specified by the EPA Intercomparison Studies Program.A total of twenty-four blank milk samples were analyzed, with an average activity of 1.410.5E+00 pCi/liter of strontium-90.
Gross Beta-Water Fifty-three blanks were prepared from distilled water.The average result, without considering detection limits, was 2.7+1.7E-Ol pCi/liter.
No contamination was indicated and the background level was low and stable.During 1992 fifty-three gross beta spike samples were analyzed during 1992, with a spike level of 2.2i 0.5 pCi/liter.
The average result was 2.211.7E+Ol pCi/liter.
This was well within the guidelines outlined in Table 2 of EPA-600/4-81-004.
Tritium in Water Thirty-six blank samples were analyzed by gas counting.The average result was-5.017.8E-01 pCi/liter.
Thirty-seven tritium samples with a spike level of 1.5i0.2E+03 pCi/liter were analyzed by gas counting during 1992.The average result was 1.4+0.1E+03 pCi/liter.
Fifty-three blank samples were analyzed by liquid scintillation.
The average result without considering detection limits was 3.213.0E+02 pCi/liter.
Fifty-three tritium samples with a spike level of 1.510.2E+04 pCi/liter were analyzed by liquid scintillation during 1992.The average result was 1.4+0.1E+04 pCi/liter.
Gamma S ectrosco A blank water sample was analyzed on a weekly basis in the gamma spectroscopy laboratory.

No corrective action necessary.(e)All lab data sheets were verified for accuracy.Three different detectors were used with aliquot ingrowth times of 9 and 19 days.Results ranged from 4 to 6 pCi/1.Dilution error has been determined to be the probable cause for the deviation from the spike value.Internal biweekly spike analyses have been in control.Corrective action includes implementation of a dilution form to record aliquot and solvent volumes.Entries will be made by the technician and reviewed by the supervisor.(f)An investigation is being conducted; the results will be available shortly.(g)There is no apparent reason for the high cesium-137 results.The sample geometry and detector efficiencies were verified to be correct.The Total K and iodine-131 by gamma spectroscopy were in good agreement with EPA values.There is no trend and results were within i3 sigma so no action taken.C-5 80 60 O 40 20 0 20 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl k 3 Sigma 4 EPA 2 3 Sigma FIGURE C-I EPA CROSS CHECK PROGRAM-S ALPHA IN AIR PARTICULATES 160 140 120 100 0$~O 80 60 40 20 1981 1982~1983 1984 1985'1986 1987 1988 1989 1990 1991 1992 1993'8/25/89 EPA test invalid.Tl 2 3 Sigma 4 EPA t 3 Sigma FIGURE C-2 EPA CROSS CHECK PROGRAM-GROSS BETA IN AIR PARTICULATES CD CJl I Pl M I Ol LLI C5 U I CO CD CC O C/l CA CD CZ'.Lal Ol CO Cl)CI C4 al O CQ tedlagogC-8 80 60 O 40 l0 0 20 20 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl a 3 sigma 4 EPA a 3 sigma FIGURE C-4 EPA CROSS CHECK PROGRAM-CESIUM-137 IN AIR PARTICULATES 80 O 40 0 0 20 1081 1082 108$1084 1985'l98d 1987 108S 1089 1000 1991 1002 1092 Tl 2 3 sigma 0 EPA 23 sigma Strontium-89 I 4 40 O CL~20 1081 1082 1083 1084 1985 1088 1087 1088 1980 1900 1001 1002 1003 TI 2 3 sigma<EPA 23 sigma Strontium-90 FIGURE C-5 EPA CROSS CHECK PROGRAM-STRONTIUM IN MILK C-10 140 120 I 80 60 40 20 20 1981 1982'l 983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl f 3 sigma 4 EPA i3 sigma FIGURE C-6 EPA CROSS CHECK PROGRAM-IODINE-131 IN NII.K 80 Q 6O 0 a 40 20 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl 13sigma 4 EPA 13sigmaFIGURE C-7 EPA CROSS CHECK PROG-CESIUM-137 IN MILK 140 120 L 80 0 60 40 20-20 1984 1985 198e 1987 1988 1989 1990 1991 1992 1993 Tl 2 3 Sigma 4 EPA X 3 Sigma FIGURE C-8 EPA CROSS CHECK PROGRAM-GROSS ALPHA IN WATER 220 200 180 160 140 Q 120 0 100 80 60 40 20 0-20 1987 1988 1989 1990 1991 1992 1993 Ti i 3 sigma 4 EPA t 3 sigma1 FIGURE C-9 EPA CROSS CHECK PROGR GROSS BETA IN MATER

SUMMARY

The Washington Public Power Supply System Radiological Environmental Monitoring Program (REHP)activities during 1992 are discussed in this report.The objective of the REHP is to determine the radiological impact, if any, of Plant 2 operations on the environment.

To accomplish that objective, air, water, milk, soil, sediment, fish and garden produce samples were collected on a regular basis from the region surrounding the plant.In addition, direct radiation from the plant and plant effluents was measured using thermoluminescent dosimeters (TLDs).Determining whether plant operations significantly affected the environment involved comparison of samples taken in areas near the plant and in other regions which could be potentially impacted by Plant 2 effluents to samples taken in areas that are highly unlikely to be affected.In addition, a comparison of the samples taken during 1992 at locations of potential impact to samples taken at the same location prior to plant operation and during previous periods of operation provided another mechanism for detecting any changes in the environmental radioactivity attributable to Plant 2 operations.

Other methods used to evaluate the REHP results and to bring the results into perspective included comparison of the 1992 results to the lower limits of detection (LLDs)determined for each radionuclide, to the preoperational averages and to the applicable State of Washington or U.S.Nuclear Regulatory Commission investigation or reporting levels or other standards.

Intercomparison programs or studies, through which the accuracy of the REHP analytical results and TLD results are demonstrated, were an important part of the quality assurance activities during 1992.Such intercomparisons tested the performance of the Supply System monitoring program against other monitoring programs and also against known values.The Supply System REHP performed well in the Environmental MeasurementsLaboratory (EHL)and Environmental Protection Agency Intercomparison Studies conducted during 1992.The 1992 results for the routine REHP sampling locations are consistent with the results for previous years.No significant new trends or changes in the environmental levels around the plant were evident at these locations.

The data from two of the special interest stations, the storm drain and the sanitary waste treatment facility, reflect the problems which occurred at those locations during 1992.The Sanitary Waste Treatment Facility received sewage from the U.S.Department of Energy's Fast Flux Test Facility (FFTF).The radionuclides accumulating in its stabilization ponds, cobalt-60, cesium-137, and tritium, remained at low levels and did not exceed any state or federal regulations or standards.

The Plant 2 storm drain pond, however, received radioactive effluents from the plant during the year and the levels of several radionuclides exceeded state and federal limits.A special report was submitted to the Nuclear Regulatory Commission (NRC)in July 1992, documenting the release of radioactivity to the pond in Hay.Subsequent notifications were made to the State of Washington and to the NRC when additional radioactivity or changes in the levels were-observed.Corrective actions were taken by the plant to prevent a recurrence of the May release and to isolate potential sources of radioactivity to the storm drain.Although the levels of radioactivity at the storm drain exceeded some state and federal limits, the radioactivity at the site has no impact on the exposure rate at the site or to member's of the public off-site.The storm drain outfall and pond is within the Plant 2 restricted area and is fenced, so access is limited.The release in Hay and the accumulation of 1-1 radioactivity at the storm drain pond have no impact upon the radiation dose to the public from plant operations.

The other special interest location, the containerized storage area, consisting of large metal containers holding low pressure turbine parts removed during the 1992 maintenance outage, showed no detectable radioactivity, aside from that which is naturally-occurring.

Becquerel (Bq): One disintegration per second.One picocurie (pCi)equals 0.037 becquerel.

Blank Sample: A sample of the same media as the field sample being analyzed but without the radionuclide(s) being measured.It enables correction for the inherent sample background.

Composite Sample: A series of single collected portions (aliquots) analyzed as one sample.The aliquots making up the sample are collected at time intervals that are very short compared to the composite period.Control Station: A background sampling location, i.e., a location not likely to be affected by plant effluents due to its distance and/or direction from Plant 2.Curie (Ci): 3.7 x 10'isintegrations per second.DOH: Washington State Department of Health.EFSEC: Energy Facility Site Evaluation Council.FFTF: U.S Department of Energy's Fast Flux Test Facility west of Plant 2.Flow-Proportional Sampling: Sample collection volume or frequency determined as a function of the flow rate of the water being sampled.Grab Sample: A single discrete sample drawn at one point in time.Indicator Station: A sampling location that could be affected by plant effluents due to its proximity and/or direction from Plant 2.Lower Limit of Detection (LLD): Detection capability.

The smallest concentration of radioactive material in a sample that will yield a net count (above system background) that will be detected with 95%probability and a 5%probability of a false conclusion that a blank observation represents a"real" signal.Mean: The average, i.e., the sum of results divided by the number of results.Milliroentgen (mR): I/1000 Roentgen;a unit of exposure to X or gamma radiation.

NIST: National Institute of Standard and Technology.

NRC: U.S.Nuclear Regulatory Commission.

ODCH: Offsite Dose Calculation Manual, which contains the program requirements formerly contained in the Technical Specifications.

3.0 INTRODUCTION

The Radiological Environmental Monitoring Program (REHP)for Washington Public Power Supply System Plant 2 provides for the collection and analysis of samples of various environmental media, in order to assess the radiological impact of plant operations.

The environmental media routinely sampled by the REHP include air, water, milk, soil, river sediment, fish, vegetables, fruits, and root crops.Other sample media, such as vegetation and animal products (for example, eggs and meat)are also sampled under special circumstances when additional information about particular radionuclides is needed.The direct radiation near the plant and at various distances from the plant is assessed through the use of thermoluminescent dosimeters.

Although no longer a routine requirement of the REHP, pressurized ionization chambers are also used to assess the direct radiation at various locations.

This annual report is written to satisfy the requirements of Plant 2 Technical Specification 6.9.1.10.The results of environmental measurements made during CY 1992 are presented in the report.The results are discussed and interpreted by comparing them to similar measurements made during the preoperational and previous operational periods and to the detection capabilities associated with the current methods of analysis.The quality assurance and quality control aspects of the program are also discussed in this report.3.1 Site Descri tion Washington Public Power Supply System Plant 2 is located in a sparsely populated shrub-steppe region within the Department of Energy-operated Hanford Site in southeastern Washington.

The plant is approximately three miles west of the Columbia River and is surrounded on all sides by uninhabited desert land.The nearest population centers are Richland, Kennewick and Pasco, which are 12 miles south, 21 miles southeast, and 18 miles southeast, respectively.

The nearest privately-owned lands are located approximately four miles ENE of the plant, across the Columbia River.Given the prevailing wind directions, shown in the 1992 wind frequency distribution in Figure 3-1, the focus of REHP sampling is this farming region across the river.Because Plant 2 is located on the Hanford Site, other sources of radioactive effluents are in relatively close proximity to Plant 2.For this reason, sampling locations near the plant (near-plant locations) provide useful information for separating the potential environmental effects of Plant 2'rom the effects of the other effluent sources on the Hanford Site.3.2 Pro ram Back round The REHP is designed to conform to the regulatory guidance provided by Regulatory Guides 4.1"'nd 4.8'", including the Radiological Assessment Branch Technical Position (BTP)"', while taking into account site specific characteristics.

The quality assurance aspects of the program and the thermoluminescent dosimetry are conducted in accordance with Regulatory Guides 4.15"'nd 4.13"'.The REHP also must adhere to the requirements of the Site Certification Agreement (SCA)'" with the State of Washington and the Plant 2 Technical Specifications'" and the Offsite Dose Calculation Manual (ODCH)"'.These.requirements cover not only the environmental sampling and sample analysis aspects of the program,'ut also the reporting and quality assurance aspects of the program.3-1 The preoperational phase of the program, which extended from March 1978 to January 19, 1984, the date of initial criticality, provided a.baseline of environmental data.Variability in the background levels of radioactivity due to differences in geologic composition, nuclear weapons test fallout, meteorological conditions and seasonal changes is reflected in that preoperational data.REHP environmental samples have always been analyzed by a contract analytical laboratory.

Since June 1986, Teledyne Isotopes, Inc.in Westwood, New Jersey, has performed the analysis of REHP samples.'he thermoluminescent dosimeters used in the REHP to assess the direct radiation are processed by the Supply System External Dosimetry Laboratory within the Health Physics Department.

3.3 Pro ram Ob'ectives The REHP is the final stage in a series of monitoring programs that characterize and analyze the liquid and gaseous effluents from Plant 2.Figure 3-2 presents this monitoring.

hierarchy from the generation of the waste liquids and gases to the calculation of doses from these effluents and the measurement of radioactivity in the environment.

The REHP provides a mechanism for determining whether the levels of radioactivity in the plant environs are within established limits and for ensuring that the accumulation of radionuclides in the environment will not become significant as a result of plant operations.

While in-plant monitoring programs are used to ensure that 10CFR20"'nd 10CFR50"'riteria for releases of radioactive effluents are met, the REHP provides supplemental verification that the concentrations of radionuclides in the environment are not greater than anticipated.

Any radiological effect of Plant 2 on the environment must be distinguished from the normal variation in background radiation levels and from the effects of other sources of radioactive effluents in the area.The monitoring results obtained during each year of the plant's operation are compared to the preoperational data and to data from previous operating years, in order to determine whether a significant accumulation of plant-produced radionuclides has occurred in the environment.

quarterly averages of the results are also compared to the Nuclear Regulatory Commission (NRC)non-routine reporting levels listed in the ODCH.In addition to evaluating the environmental concentrations against federal standards or limits, the REHP also compares the results to state standards"""""".

4.0 PROGRAM DESCRIPTION The REMP plan for Plant 2 is presented in Table 4-1.It summarizes the sample locations, collection frequency and types of analysis performed on the sample media.The methods of sampling and sampling frequencies utilized in the program have been determined by such factors as the half-lives and major exposure pathways for the radionuclides potentially released from the plant to the surrounding environment.

4.1 Sam le Locations Eighty sample locations were included in the 1992 monitoring program.Seventy three indicator and two control, i.e.background, locations were within 10 miles (16 kilometers) of the Plant 2 containment.

Three additional control stations and two indicator stations were outside the 10-mile radius from the plant.Sample stations are listed in Table 4-2 by meteorological sector, sample media and approximate distance from the plant.The numbers and locations of sample stations are based not only on factors such as population distribution and meteorological conditions, but also on station accessibility, security throughout the year and the requirements of applicable regulations.

Other factors such as the need to monitor locations which potentially could be impacted by Plant 2 operations, influence the location of REMP sampling sites.The REMP sampling locations described in Tables 4-1 and 4-2 are presented in Figure 4-1 for sampling locations within the 10-mile radius, except the special interest stations, and in Figure 4-2 for locations outside the 10-mile radius.Figure 4-3 provides a more detailed map of sampling locations in the Sunnyside/Grandview area.Figure 4-4 shows the locations of the storm drain (Station 101), the Sanitary Waste Treatment Facility (Station 102)and the containerized storage area (Station 118), which are special interest stations.Detailed drawings of sampling locations at the storm drain and the containerized storage area are presented in Figures 4-5 and 4-6.The sampling locations for each specific type of sample media are shown in Figures 4-7 through 4-15.4.2 Land Use Census The annual land use census within 5 miles of Plant 2 was performed in August.The objectives of the land use census are to identify the locations of the nearest milk animal, residence and garden greater than 50 m'500 ft)producing broadleaf vegetation and to determine whether any site located during the census has a calculated dose or dose commitment greater than the sites currently monitored for the same exposure pathway.If a new location with a higher dose commitment is found, routine sampling of that dose pathway would be initiated at that new site.The results of the 1992 land use census within 5 miles are given in Table 4-3.No significant changes'from the 1991 census were observed, except that the garden at 4.9 miles E was discontinued.

No milk animals are located within the 5-mile radius.The closest milk locations were at 6.4 miles SE and 7.2 miles ESE.Sheep were located at 4.5 miles NE and cattle are no longer at 4.7 miles ENE.4-1 4.3 Sam lin Hethods The collection of environmental samples for the REHP was performed according to the schedule in Table 4-1.All samples were collected by Supply System personnel.

Documented procedures contained in the Environmental Program Instruction Manual were used for sample collection and preparation.

The following sections describe the Supply System's sampling and preparation methods.4.3.1 Direct Radiation During 1992, thermoluminescent dosimeters (TLDs)were used to determine the direct radiation levels at the fifty-seven (57)monitoring locations shown in Figures 4-7, 4-8 and 4-9.No new TLD locations were added to the program this year, however, the special interest TLD station located at the Haymaker Farm (Station 61)in Franklin County was discontinued in June.The TLD located at Station 9A in Sunnyside served as the control, or background, TLD.The other 56 TLDs served as indicator TLDs.The environmental dosimeter consists of a card containing CaS04.Dy (25%)phosphor in a Teflon matrix.Following oven annealing at 250'C for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, the 31.75 mm x 44.75 mm x 0.4 mm thick card was loaded into a plastic case (Teledyne Model EB-2)lined with.0.58 mm copper (520 mg/cm')to lessen the TLD's over-response to low energy photons"".

The TLD was prepared for the field by first wrapping the case with aluminum foil, sealing it in two plastic bags and finally placing'it in a cotton bag, which was hung from a metal post at each site.The TLDs were hung approximately three feet above the ground.Two sets of TLDs were employed at each location.One set was exchanged on a quarterly basis and the other exchanged on an annual basis.Exposure of the field TLDs during transport to the TLD sites was monitored by a set of field control, or trip control, dosimeters that accompanied the field dosimeters to and from the field locations.

Another set of TLDs was used as building control TLDs which were used to determine the exposure of the TLDs if they remained in the lead cave during the entire quarter.The TLD exposure during transport to and from the field was determined by subtracting the difference between the building control results and the trip control results.The environmental dosimeters were processed on a Teledyne Isotopes Model 9100 Automatic Reader.Following the initial processing, the field dosimeters were annealed and given a calibration exposure of 100 mR of cesium-137 gamma, in order to determine response (i.e, calibration) factors for each dosimeter.

The calibration factors were then used to determine the total exposure received by each TLD.The exposure values determined for calibration exposures, as well as the exposures of the gA dosimeters (processing control dosimeters) and audit dosimeters (spiked dosimeters), were based on the calculated, field strength of the encapsulated cesium-137 source.The calculated field strength of the source was determined from National Institute of Standards and Technology (NIST)-traceable ionization chamber measurements made over a period of several years during the routine use and calibration of the source.Ionization chamber measurements made during TLD calibration were used to confirm the calculated exposure.If the calculated exposure and the ionization chamber reading differed by 5%or more, an investigation was performed into the calibration exposure.O.0 4-2 Three Reuter Stokes pressurized ionization chambers (PICs)provide an additional

,'apability for measuring direct radiation exposure.These units are no longer part of the routine monitoring program, but they are used in special monitoring situations and maintained as back-up monitoring systems.Solar panels provide the power sources for the units in order to prevent equipment problems and damage caused by power surges and lightning.

4.3.2 Airborne Particulate/Iodine Air particulate and air iodine (I-131)samples were obtained thr ough the use of portable, low volume (1.5 cfm)constant flow-rate sampling units at each of twelve locations.

The samples drawn at Station 9A (Figure 4-3)were considered control samples;the ones drawn at the other locations (Figure 4-10)were indicator samples.Air particulates were collected by drawing air through a 47mm-diameter glass fiber filter.Air iodine was collected by drawing air through a 57mm-diameter TEDA-impregnated charcoal cartridge.

The particulate air filter and charcoal cartridge were placed in tandem, particulate filter first, in a holder that attached to the air inlet of the sampler unit.The sampler units were placed in ventilated metal weatherproof housings mounted on elevated platforms at each air sample location.The air sampler units were run continuously, with the filter and charcoal cartridge exchanged weekly for analysis.The total sample time for each filter and cartridge was recorded from the elapsed time indicator and the sample volume was calculated and recorded.The filters and cartridges were shipped or delivered to the analytical contractor within one or two days of collection.

4.3.3 Water The water sampling network consisted of nine sampling locations:

three for the evaluation of river/drinking water, one for discharge water, three for ground water, one for the storm drain water, and one for the sanitary waste water.The locations of these sampling sites are shown in Figures 4-4, 4-5, 4-11, and 4-12.The sampling locations at the storm drain and the sanitary waste treatment facility are shown in Figures 4-12 and 5-17.One river/drinking water location, Station 26, was used for evaluation of the plant intake water, i.e., the river water taken upstream of the plant discharge point.This Station 26 sample can be consid'ered a drinking water sample since the site draws its drinking water from the intake water.It is considered the river/drinking water control sample because of its upstream location.Two additional locations, Stations 28 and 29, were used to evaluate the water at the two nearest drinking water.locations,.the, Department of Energy 300 Area and the Richland Water Treatment Plant.These two stations were considered indicator stations.The ODCH requirement for a downstream water sample"near but beyond the mixing zone" was met by sampling water from Station 27, the plant discharge line to the Columbia River.This sample reflects the radioactivity present in the plant discharge prior to any river dilution, rather than the concentrations that would be found after dilution in the mixing zone.Water is drawn at this location because it was not feasible to perform flow-proportional composite sampling in the mixing zone area of the river downstream from the plant discharge point.This Station 27 sample is also considered an indicator sample.TEDA: Triethylene diamine 4-3 0'omposite samplers are installed at the two drinking water locations (Stations 28 and 29)and the control location (Station 26)to periodically collect 25-ml aliquots of water at a regular time interval.These aliquots are added to large collection bottles.At the prescribed intervals, the sampler collects, alternately, an aliquot for the sample designated for gross beta and gamma isotopic analyses and an aliquot for the sample designated for tritium analysis.Two composite samplers draw samples from the discharge line (Station 27).They operate in a flow-proportional mode through a complex system that adjusts the'ampling frequency relative to the flow rate in the discharge line.Only one of the samplers operates at any given time, while the other sampler is maintained ready to use when needed.Prior to the start of each monthly sampling period, concentrated nitric acid was added to the large collection bottles receiving the gross beta and gamma isotopic water samples to inhibit biological growth and plateout of dissolved ions on the bottle wall.Acid was not added to the collection bottles receiving the water samples for tritium analysis.One gallon of each of the gross beta samples was poured into a clean plastic cubitainer each month.A 250-ml cubitainer was used to hold the monthly sample submitted for the quarterly tritium composite.

Nonroutine analyses on the drinking water samples include strontium-90 analysis, when the gross beta activity exceeds 8 pCi/liter or ten times the mean of the previous three months'ctivity for a specific location, and iodine-131 analysis, when the dose calculated for the consumption of water exceeds one mrem per year.Neither of these analyses were required during 1992.The three groundwater stations are located on Supply System property: one well on the Plant 2 site (0.I mile north of the Reactor Building)and two wells on the WNP-I site (1.2 miles downgradient from Plant 2).These locations are shown in Figure 4-12.Water from the Plant 2 well can be used as a backup source for drinking and fire protection.

Water from the WNP-I wells supplies the drinking and fire protection water for the WNP-I site.All three groundwater samples are considered indicator samples.quarterly grab samples were taken from each of these wells.One gallon was collected from each well for gamma analysis and 250 ml was drawn for tritium analysis.The gamma analysis samples were acidified with nitric acid.The tritium samples were left unacidified.

Water samples were also collected from two special interest locations, the storm drain, Station 101, and the Sanitary Waste Treatment Facility (SWTF), Station 102.Until, November, grab samples were taken from the water at these two locations on a frequency ranging from daily to quarterly, depending upon sampling need.In November a composite water sampler was installed at the outfall of the storm drain pipe, so aliquots were collected on an hourly basis to form a daily composite sample.These aliquots were collected hourly regardless of flow through the pipe.Flow measurement devices will be installed at the pipe outfall during 1993, so that aliquots can be collected on a flow-proportional basis.Sanitary pond water samples, however, have continued to be grab samples.Storm drain and sanitary waste water samples were acidified and handled as described above for the other types of water.-

4.3.4 Soil Soil samples were collected once during 1992, from four locations required by the Site Certification Agreement.

The four locations (Stations 1, 7, 21 and 23)are shown in Figure 4-13.One sample was taken at the control location, Station 9A (Figure 4-3).quarterly soil samples were collected at two special interest locations, Station 101 and Station 118, as shown in Figures 4-4, 4-5 and 4-6.Two additional samples were collected at the Haymaker Farm (Station 61)located at 6.5 miles southeast of Plant 2.This sampling was performed at the owner's request.Each sample was taken from an area of approximately one square foot and a depth of approximately one inch.Approximately two kilograms of soil were used in each sample.Soil samples were shipped to the analytical contractor within ten working days after collection and analyzed for gamma activity.If the gamma isotopic analysis indicated that cesium levels in any of the indicator samples exceeded ten (10)times the level in the control sample, a strontium analysis was performed on the sample(s).

During 1992, strontium analysis was required for Station 23 soil sample only.4.3.5 Sediment-0 Sediment samples were collected twice during 1992 from two sampling locations along the Columbia River.The upstream sediment sample (Station 33)was collected from a location approximately two miles up the Columbia River from the plant discharge point.The downstream sample location (Station 34)was collected from a location approximately one mile downstream of the discharge point (Figure 4-14).Samples were scooped from under water near the river shoreline.

Each sample consisted of approximately two kilograms of the shallow surface sediment.The samples were placed in clean plastic bags and shipped to the analytical contractor within a day or two of collection.

Sediment samples were also taken from the outfall and pond bed of the storm drain pond and the settling ponds, dosing pond, percolation bed, and overflow basin at the Sanitary Waste Treatment Facility.Sediment sampling in these locations was performed in a similar manner to river sediment sampling.Special care was taken to prevent loss of the fine particulates.

in the sediment.In addition, formalin was added to the sanitary pond sediment prior to shipping, to inhibit gas formation within the sample container.

4.3.6 Fish Fish sampling was performed during May and October, when the likelihood of obtaining anadromous species was high.Fish samples collected from the Columbia River (Station 30 in Figure 4-1)were indicator samples, while the fish collected on the Snake River (Stations 38 and 38A in Figure 4-2)were control samples.Four separate fish samples, consisting of an anadromous species and three other species generally considered edible or potentially edible (such as carp, catfish and whitefish), were collected at each location.Host of the fish were collected Fish, such as salmonids, which ascend rivers from the sea for breeding.4-5 through the use of electro-shock, but samples of the anadromous species were also collected from the Lyons Ferry Fish Hatchery on the Snake River.The fish were filleted to obtain one kilogram of edible flesh per sample.The fillets were placed in clean plastic bags and frozen until shipment to the analytical contractor.

Fish samples were shipped within 14 days of collection.

During 1992, the Site Certification Agreement was changed to require only annual fish sampling, unless a plant impact was observed.If that were to happen, semiannual sampling would be resumed.4.3.7 Milk 0~, Milk samples were collected monthly during January, February, March, October, November and December and semimonthly during the remaining six months when the cows were likely to be grazing.One gallon of raw milk was collected from each sampling location.The milk samples were chilled thoroughly and shipped to the analytical contractor within a day of collection.

Routine samples were collected from five indicator locations (Stations 36, 40, 59, 62 and 64)across the Columbia River in Franklin County, as shown in Figure 4-15.Milk samples were taken from Station 59 for only the last half of the year, since milk production resumed at this location in June.Samples were also collected at one indicator station (Station 9B)and one control location (Station 96)in the Sunnyside/Grandview area (in Figure 4-3).Station 9B in Grandview continued to serve as an indicator station in 1992 because a portion of the feed for the cows at that location is hay from the north Pasco area of Franklin County.That factor makes it unsuitable for use as a control location.~.4.3.8 Garden Produce Samples of local garden produce were collected monthly from April to September, when the produce was readily available.

When possible, three types of produce samples--a root crop, fruit and a leafy vegetable--were collected at each location.The indicator samples were collected from a region in a predominant downwind direction (Station 37 in Figure 4-2)where crops are irrigated with Columbia River water.The control samples were obtained from produce stands in the Sunnyside area (Station 9C in Figure 4-3), the direction least likely to be affected by plant effluents.

In addition, apples were collected in September from Station 91, the Rio.Vista Farms orchard, which is irrigated with Columbia River water and cherries were collected in June from Station 61, the Haymaker Farm.These produce samples were shipped to the analytical contractor within two days of collection.

4.3.9 Vegetation

Samples of vegetation growing in the storm drain pond bed were collected periodically during 1992.Cattails and grasses were the principal types of vegetation collected.

Approximately two kilograms of sample were collected each time.Care was taken to avoid including the roots or soil from around the roots in the samples.The vegetation samples were then shipped to the analytical contractor within two days of collection.

~'-6 4.3.10 Snow 1 Snow is not routinely sampled by the REHP.During 1992, however, snow samples were taken in order to gather information concerning tritium levels in the environment around Plant 2.Each sample consisted of fresh snow collected in a'plastic or teflon container placed outside during snowfalls or collected by shoveling all the snow, from ground level to the top, in a designated area.The volume of snow collected was sufficient to provide at least a one-liter water sample for analysis.The samples were shipped to the analytical contractor within two days of collection.

4.4 Anal tical Procedures The analytical procedures used for the 1992 REHP samples are described below.Teledyne Isotopes performed all routine analyses of REHP samples during 1992.4.4.1 Gross Beta Activity on Particulate Filters The particulate filters were counted in a gas-flow proportional counter after a delay of five or more days to allow for the radon-222 and radon-220 (thoron)daughter products to decay.An unused air particulate filter was counted as the blank with each weekly set of'ilters.

4.4.2 Measurement

of Gamma Emitters Milk and Water A 1-liter Harinelli beaker was filled with a representative aliquot of the sample.The sample was then counted for at least 1000 minutes (16.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />)with a shielded Ge(Li)detector.Foodstuff As much of the edible portion of the sample as possible was loaded int'o a tared Harinelli beaker and weighed.The sample was then counted for at least 1000 minutes (16.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />)with a shielded Ge(Li)detector.~Ve etation As much sample as possible is placed in a 1-liter Marinelli beaker and counted for approximately 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> with a shielded Ge(Li)detector.The sample is not dried prior to counting, so the results are given in terms of wet weight.Soils and Sediments A large quantity of the sample was dried at a temperature below 100'C.As much sample as possible was loaded into a tared 1-liter Harinelli beaker and weighed.The sample was then counted for at least 360 minutes (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />)with a shielded Ge(Li)detector.4-.7 Charcoal Cartrid es Air Iodine Charcoal filters were counted up to five at a time, with one positioned on the face of a Ge(Li)detector and up to four on the side of the Ge(Li)detector.Each Ge(Li)detector was calibrated for both positions.

The detection limit for iodine-131 on each charcoal cartridge was determined (assuming no positive iodine-131) uniquely from the volume of air which passed through it.In the event that iodine-131 would have been observed in the initial counting of a set, each charcoal cartridge in the set was then positioned separately on the face of the detector and counted.0 Air Particulate Filters Four air particulate filters for a quarterly composite for each field station were aligned one in front of another and then counted for at least 360 minutes (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />)with a shielded Ge(Li)detector.The shielded Ge(Li)detector was coupled to a mini-computer-based data acquisition system which performed pulse height analysis.A mini-computer software program defined peaks by certain changes in the slope of the spectrum.The program also compared the energy of each peak with a library of peaks for isotope identification and then performed the radioactivity calculation using the appropriate fractional gamma ray abundance, half-life, detector efficiency, and net counts in the peak region.,4.4.3 Gross Beta Activity in Water A one-liter aliquot of each sample was evaporated to a small volume and transferred to a stainless steel planchet.The sample was dried under heat lamps, cooled, then counted on an automatic beta proportional counter.The results were calculated using empirical self-absorption curves which enabled the correction of effective counting efficiency, based on the sample residue mass.4.4.4 Iodine-131 in Water~.Two liters of sample were first equilibrated with stable iodide carr ier.A batch treatment with anion exchange resin was used to remove iodine from the sample.The iodine was then stripped from the resin with sodium hypo-chlorite solution, reduced with hydroxylamine hydrochloride and extracted into carbon tetrachloride as free iodine.It was then back-extracted as iodide into sodium bisulfite solution and precipitated as palladium iodide.The precipitate was weighed for chemical yield and mounted on a nylon planchet for low level beta counting.The chemical yield was corrected by measuring the stable iodide content of the water with a specific iop electrode.

During 1992, this procedure was used only on intercomparison samples, since the doses calculated via ODCM methodology for the consumption of drinking water did not exceed 1 mrem per yea}(Table 4-1, footnote n).4.4.5 Tritium in Water During the first half of 1992, the tritium analyses were performed using gas counting techniques.

Approximately two milliliters of water were converted to hydrogen by passing the water, heated to its vapor state, over a granular zinc conversion column heated to 400'C.The hydrogen was loaded into a one-liter proportional detector and the volume was determined by recording the pressure.4-8 The proportional detector was passively shielded by lead and steel and an electronic, anti-coincidence system provided additional shielding.

from cosmic rays.From July to the end of the year, Supply System samples were analyzed for tritium.using liquid scintillation.

Liquid scintillation requires 10 milliliters of water mixed with 10 milliliters of liquid scintillation"cocktail".

The mixture is then counted in an automatic liquid scintillation detector.4.4e6 Strontium-89 and 90 in Water, Milk and Soil During 1992, strontium analyses were not required for any routine REMP water or milk samples.Strontium analysis was required for one routine soil sample (Station 23)which had cesium-137 levels ten times greater than those measured for Station 9A, the control location.It was also used for special and intercomparison water and sediment analyses.The techniques used to analyze for strontium in the various media are described below.Water Stable strontium carrier was added to one liter of sample and the volume was reduced by evaporation.

Strontium was precipitated as Sr(N03)~using fuming (90%)ni tri c ac i d.Milk Stable strontium carrier was added to one liter of sample.The sample was then evaporated and ashed in a muffle furnace.The ash was dissolved and strontium was precipitated as a phosphate.

It was then redissolved and strontium was precipitated as Sr(N03), using fuming (90%)nitric acid.Soil and Sediment The sample was first dried under heat lamps and a 10-gram aliquot was taken.Stable strontium carrier was added and the sample was leached in hydrochloric acid.The mixture was filtered.Phosphates were then precipitated, collected by filtration and dissolved in nitric acid.Strontium was precipitated as Sr(NO~)2 using fuming (90%)nitric acid.A barium chromate scavenge and an iron (ferric hydroxide) scavenge were then performed.

Stable yttrium carrier was added and the sample was allowed to stand for 5 days or more for yttrium ingrowth.Yttrium was then precipitated as hydroxide, dissolved and reprecipitated as oxalate.The yttrium oxalate was mounted on a nylon planchet and counted in a low-level beta counter to infer strontium-90 activity.Strontium-89 activity was determined by precipitating SrCO, from the sample after yttrium separation.

This precipitate was mounted on a nylon planchet and covered with an 80 mg/cm aluminum absorber for low-level beta counting.4.4.7 Iodine-131 in Mi 1 k Two liters of sample were first equilibrated with stable iodide carr ier.A batch treatment with anion exchange resin was used to remove iodine from the sample.The iodine was then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride and extracted into carbon tetrachloride as free iodine.It was then back-extracted as iodide into sodium bisulfite solution and precipitated as palladium iodide.The precipitate was weighed for chemical yield and mounted on a nylon planchet for low-level beta counting.The 4-9 chemical yield was corrected by measuring the stable iodide content of the milk with a specific ion electrode.

4.5 Data Anal sis Methods Since mid-1984, the results of the REMP analyses have been given as net results calculated from the gross or total counts determined for each radionuclide minus the background counts of the counting or detection instrument.

Consequently, for several sample types, the results range from negative to positive numbers.This manner of presenting environmental data prevents the bi as and loss of individual results inherent in the use of"less than" (<)values, where the"less than" numbers can have a variety of meanings, such as"less than the lower limit of detection (LLD)" or"less than the two sigma uncertainty." The net results for REMP samples are presented with an asterisk (*)in front, if the results are less than.the LLD.A listing of the LLDs determined for each analysis is provided in Table 5-2 as a reference when reviewing the sample results.Plots of the, sample results versus time are used to represent the results for analyses such as gross beta on air particulate filters, where the results are normally above the lower limits of detection.

In such cases, the indicator station results are plotted with the control station results for easy comparison.

Other data analysis techniques, such as frequency distributions, are also used to represent the data and to determine whether trends that could be attributed to Plant 2 operations are evident.Thermoluminescent dosimeter (TLD)data is presented in terms of the net mR/day.exposure rate.These results are determined from the total exposure (in mR)calculated for each TLD from its total thermoluminescent output minus the TLD background, minus any transit (or trip)exposure received during distribution and retrieval, and divided by the number of days the TLD was in the field.Circular plots, frequency distributions and graphs of TLD data by meteorological sector and distance from the plant are used to interpret trends in the results.TLD data summaries include the term"standard error," along with"standard deviation." The standard error, which is the estimate of the precision of the mean, is used for the means of quarterly and annual data.The standard deviation is used for the TLD data involving a single dosimeter result that has been determined from the four reader areas of the TLD.Both terms simply provide an indicator of the uncertainty associated with the results.Oo 4-10 TABLE 4-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM PLAN SAMPLE TYPE"'.AIRBORNE SAMPLE STATION+'UMBER SAMPLING AND COLLECTION FREQUENCY" TYPE AND FREQUENCY OF ANALYSIS Particulates and radioiodine 1, 4-9A 21, 23, 40, 48, and Continuous sampling;weekly (6/12)"'7 collection Particulate:

, seasonal avai 1 abi 1 i ty , malfunction of automatic sampling equipment, or other legitimate reasons.Such deviations are documented in Appendix D.

TABLE 4 ont.)Gamma isotopic means identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents of Plant 2.Soil samples are collected to satisfy the requirements of the Site Certification Agreement (SCA)for Plant 2.The SCA requires that soil samples be collected at five air sampling locations.

Strontium-90 analysis shall be performed on any indicator soil sample having cesium results greater than ten times the results for the control location.During 1992, strontium 90 analysis was performed on the Station 23 soil.TLD refers to thermoluminescent dosimeter.

For purposes of the REHP, a TLD is a phosphor card (31.75mm x 44.75mm x 0.4mm)with eight individual read-out areas (four main dosimeter areas and four back-uq dosimeter areas)in each badge case.TLDs used in the RENP meet the requirements of Regulator Guide 4.13 and ANSI N545-1975', except for specified energy-dependence response.Correlation factors are available for energy ranges with response outside of specified tolerances.

TLD Stations 71-86 are special interest stations and are not included among the 34 routine TLD stations required by the Plant Technical Specification Table 3.12-1.Their alternate designations are 1S-16S.Station 61, a special interest location, was discontinued in June.The SCA requires that 25 or more TLD stations are located within a 10-mile radius of the plant.Pressurized ion chambers (PICs)are not required as part of the routine monitoring program, but they are required by the SCA to be maintained as a supplemental or backup system.PICs were used routinely at various locations during 1992 to provide supplemental information.

The term"river/drinking water," instead of"surface/drinking water", is used throughout this report because the surface water is taken from the Columbia River.Station 26, Plant 2 makeup water intake from the Columbia River is both an upstream surface, or river, water sample and the drinking water control sample location.Station 28 (300 Area)and Station 29 samples are drinking water samples.The Station 27 sample, which is drawn from the plant discharge line, is taken in place of a"downstream" water sample near but beyond the mixing zone.It reflects the radioactivity present in the plant discharge prior to any river dilution.The SCA requires two drinking water locations downstream from the plant discharge and requires sampling from the plant intake and discharge water.Station 101, the storm drain pond,'and Station 102, the Sanitary Waste Treatment Facility, are represented individually because they are unique sampling locations requiring special attention.

Composite (integrated grab)samples are collected with equipment which collects an aliquot at time intervals that are short relative to the compositing period.When the gross beta activity in drinking water exceeds 8 pCi/liter, a strontium-90 analysis is performed.

TABLE 4-1 (Cont.)When the dose calculated vi a ODCN methodology for consumption of water exceeds I mrem per year, iodine-13 1 analyses are performed on the drinking water sampl es.The SCA requires sampling from wells used for fire protection and as backup drinking water sources.The SCA requires sediment sample collection upstream and downstream of the plant discharge.

Milk samples will be obtained from farms or individual milk animals which are located in the most prevalent wind directions from Plant 2.Routine milk samples are collected in areas of high dose potential instead of within 5 kilometers, due to the locations of milk animals.The SCA requires at least three-milk locations within the 10-mile r'adius of the plant and one in a control location.Station 96 is the control station for milk samples because it was determined that the cows at Station 9B in Sunnyside were given feed grown in the Franklin County area across the Columbia River from Plant 2.Station 59 was reestablished as a milk location in June 1992.If cesium-134 or cesium-137 is measured in an individual milk sample in excess of 30 pCi/1, then the strontium-90 analysis will be performed.

There are no commercially important species in the Hanford Reach of the Columbia River.Host recreationally important species in the area are anadromous'(primarily salmonids), which ascend rivers from the sea for breeding.Four fish specimen will normally be collected by electroshock technique in the vicinity of the plant discharge (Station 30)and from the Snake River (Station 38).If electroshocking produces insufficient anadromous fish samples from the Snake River, samples may be obtained from the fish trap at Ice Harbor Dam, Lyons Ferry Fish Hatchery, or other similar facility (Station 38A).If insufficient anadromous fish samples are produced through electroshocking on the Columbia River, samples may be obtained at the Ringold Fish Hatchery (Station 39).The SCA requirement for semiannual fish sampling was changed to annual sampling.This change will be implemented in 1993.Garden produce will routinely be obtained from farms or gardens using Columbia River water for irrigation.

One sample of a root crop, leafy vegetable, and a fruit is collected each sample period;if available.

The variety of the produce obtained will be dependent on seasonal availability.

Station 61 is the Haymaker Farm, which has a large cherry orchard.A cherry sample is collected in June each year.Station 91 is an apple orchard irrigated by the Columbia River.'he apple crop from Station 91 is sampled annually.0 0 TABLE 4-2 REMP SAMPLE LOCATIONS BY SECTOR SECTOR" STATION~b~

Table 5-1 presents the means and ranges of the 1992 results for each type of sample collected.

The means and ranges of the preoperational and the previous operational data from 1984 to 1991 are also included in the table for comparison.

The data for the preoperational period and the first six months of 1984 included"less than" (<)designations for results below the actual LLD, the contractual LLD or the two sigma error, depending upon the convention employed by the analytical contractor.

Consequently, the data averages using"less than" values are biased high.The use of the"less than" values was discontinued in mid 1984.Since then, REHP data have been reported as net results (total)results minus the detector counting background).

Since the primary focus of the REHP is to determine whether Plant 2 operations have impacted the environment, the 1992 results are compared in this report to the results during the preoperational period and the results obtained during the previous years of Plant 2 operation.

They are compared, as well, to state and federal regulatory limits.Because of the use of"less than" values, rather than net results, during the preoperational period and during the first year of operation and because of the impact of the 1986 Chernobyl accident on environmental radiation levels, the interpretation of the 1992 measurements relative to previous.measurements must be done carefully.

Some of the parameters considered in the evaluations discussed in this report are the means, ranges and standard deviations or standard errors of the results.Comparative plots and frequency distributions of the data are some of the tools that have been employed in the interpretation of the 1992 REMP data.The 1992 analytical results for the REMP sampling locations established since the preoperational period are very similar to the results reported for previous years.The 1992 annual and quarterly TLD results were also very much like those observed previously.

No significant trends indicating an environmental impact or unexpected change in the environmental concentrations or exposure rates at these stations was observed.At two of the special interest locations, Station 101 and Station 102, there were significant changes observed.At Station 101, the storm drain, there has been some environmental impact, the most significant of which is the contamination of the sediment and soil in and beneath the pond.The changes observed at Station 102, the Sanitary Waste Treatment Facility, were very low level and were considered to have no impact on the environment.

At Station 118, the containerized storage area, radionuclide concentrations were at normal background levels.The LLDs generally determined by Teledyne Isotopes for each analysis performed and each radionuclide of interest are listed in Table 5-2.Presented alongside the Teledyne LLDs are the LLDs required by the NRC Branch Technical Position (BTP)."'he LLDs determined for analyses at Teledyne Isotopes have met the NRC requirements in all cases.5-1 A summary of the 1992 results that were detectable is presented in Table 5-3.If a particular radionuclide of interest was not detected in the 1992 samples the term"LLD" is noted in the data mean and range columns.5.1 Direct Radiation Summaries of the environmental radiation exposure rates, determined by thermoluminescent dosimeters (TLDs)are presented in Tables 5-4 and 5-5.The individual quarterly and annual results for each TLD station are given in Tables A-1.1 and A-1.2 of Appendix A.Figures 5-1 and 5-2 show the mean quarterly results for near-plant and remote TLD locations for the preoperational period, 1984-1991 and 1992.Figures 5-3 and 5-4 show the annual TLD results for near-plant and remote locations for the same periods.The quarterly and annual results for the control location (Station 9A)show similar fluctuations over time as the indicator locations and the relationships between the different locations remain very consistent over the three periods.Figure 5-5 presents a circular plot of the mean 1992 quarterly TLD results for each of the sixteen meteorological sectors, compared to the sector means for.the preoperational and previous operational periods.The relationship of the mean 1992 results to the results for the preoperational and previous operational periods is very similar for each sector.This indicates that there were no significant directional effects observed in the 1992 TLD results.The apparent increase in the mean 1992 TLD results over the means of the preoperational and previous operational periods is due to the effect of averaging only the four quarters of 1992 data, versus averaging numerous quarters for the other two sets of results.The differences between the data sets are generally within 10%, which is within the range of variation normally expected for TLD systems.The annual TLD results for each sector also follow the same pattern as the mean quarterly results, except they are approximately 5%lower.Station 46 in the Wahluke Reserve remained the location with the highest mean exposure rate, 0.31 mR/day.This is the same mean exposure rate determined for that station for 1989, 1990, and 1991.Since the preoperational measurement phase, the results for this location have exceeded the results for all other locations.

Variations in the ambient background due to differences in the soil and underlying rock composition account for such local differences in the TLD results.A comparison of the 1992 annual and mean quarterly TLD results is presented in Table 5-6.The 1992 annual TLD results are generally 5-10%lower than the mean quarterly results because of the signal fading characteristics of calcium sulfate (CaSo4).This difference is not significant, in light of the variability commonly observed in TLD results.In most cases, the annual result is within the uncertainty associated with the quarterly TLD results.Frequency distribution plots of the 1992 quarterly TLD results are presented in Figure 5-6.The plots are very similar from quarter to quarter, with 0.26 mR/day being the most frequent result and with the Station 46 results being upscale and separate from the main distribution.

The frequency distributions for the quarterly preoperational, previous operational and 1992 TLD results are compared in Figure 5-7.The three distributions agree well.0 5-2 The 1992 annual TLD results are also consistent with results observed for the past monitoring periods.This is evident in the comparison of the current results with preoperational and previous operational results presented in Table 5-5.The above comparisons of 1992 TLD results to preoperational and previous operational data and the analysis of results by meteorological sector and distance from the plant demonstrate that Plant 2 operations have not impacted the direct radiation levels in the environment around the plant.5.2 Airborne Particulate Iodine 1 The results of the 1992 gross beta in air analyses are presented in Tables A-2.1 and A-2.2 of Appendix A.The 1992 mean weekly results of all indicator stations are plotted in Figure 5-8.The gross beta in air results for 1992 were within the ranges observed during the preoperational period and during previous operational periods, as shown in Table 5-1.In Figure 5-9 the similarity between results from near-plant locations and those from remote locations can be seen.The control location (Station 9A)results follow a very similar pattern to the remote and near-plant, indicator locations.

As observed previously, gross beta levels increased during periods of inversion occurring in the fall and winter months.In fact, the gross beta results plotted over a period of several years show a cyclic pattern of fall and winter increases.

The=increase, which was evident in the results of all the air sampling locations is due to an increase in radon and radon daughter concentrations during the inversions.

The quarterly gamma analyses of the particulate filter composites indicated only the presence of two naturally-occurring radionuclides, beryllium-7 and potassium-40, at levels above detection limits at indicator locations and the control location.The results of the gamma analysis of particulate filter composites are presented in Table A-3.1 and A-3.2 of Appendix A.The results of the gamma analyses of charcoal cartridges for iodine-131 are presented in Table A-4.1.All iodine-131 in air results for 1992 were less than the 0.01 pCi/cubic meter LLD.No evidence of any impact of plant operations on the environment was apparent in the particulate filter and charcoal cartridge results for 1992.5.3 Water The gross beta in river/drinking (including intake)and discharge water results are given in Tables A-5.1 and A-5.2 of Appendix A.All river/drinking water results were within the ranges normally observed and less than 8 pCi/liter, the level at which a strontium analysis is performed to verify compliance with the Washington State drinking water standard for strontium-90

.The 1992 gross beta concentrations in river/drinking water, relative to the state annual average concentration limit"", are presented in Figure 5-10.The mean gross beta results in river/drinking water and discharge water, for 1984 to 1992 are compared to the state annual average concentration limit (8 pCi/liter) and the DOH investigation level (75 pCi/liter), respectively, in Figure 5-11.The current average results compare well to the averages from previous periods.Strontium-90 is assumed to account for the gross beta result.5-3 The mean gross beta levels in the discharge water were slightly lower in 1991 and 1992 than the previous levels observed during the period of 1984-1990, as shown in Figure 5-11.This lower gross beta level resulted from the current mode of plant operations using less concentrated circulating water (lower cycles of concentration).

The gross beta levels in the discharge sample reflect the concentrations of naturally-occurring radionuclides, principally potassium-40, and any radionuclides from upstream sources of past Hanford activities present in the makeup water, in addition to radionuclides from Plant 2 discharges.

The discharge sample results are representative of the radioactivity present in plant discharges before any mixing with river water occurs.Therefore, the sample is not indicative of the actual radionuclide concentrations in the river water downstream from Plant 2.Flow-proportional composite sampling from the discharge line was considered to be the most feasible option for meeting the ODCN requirement for sampling from the river near the downstream edge of the mixing zone.However, careful interpretation of the results from this sampling point is necessary, since they do not represent true environmental samples.The tritium results for river/drinking water, discharge water and groundwater are presented in Tables A-6.1 and A-6.2 of Appendix A.The tritium levels in the river/drinking water were all below the LLD, except two results which were at the detection level.The mean results for 1992 are compared to previous periods in Figure 5-12.All the tritium results for the quarterly groundwater samples were below the LLD.Tritium levels in the discharge water were higher than the levels observed for the river/drinking water samples because of plant releases and because discharge water samples are taken prior to the water reaching the river and becoming diluted.As shown in Figure 5-13, the mean result was much higher than the mean levels observed for 1991 and the 1984-1990 period.The tritium concentration in the discharge water ranged from 1800 to 5400 pCi/liter, which is still low, when compared to the NRC reporting level of 20,000 pCi/liter for a quarterly average concentration in.dch"ki" d Cobalt-60, zinc-65 and cesium-137 were detected in some discharge samples during and following the plant outage.The detectable cobalt-60 results ranged from 6.6 to 20.5 pCi/liter, the zinc-65 results ranged from 14.3 to 27.9 pCi/liter, and the cesium-137 results ranged from 5.1 to 9.9 pCi/liter.

Although above detection levels, these results were low and did not exceed any reporting levels.5.4 Soil Gamma spectrometry was performed on five soil samples collected in Hay.The detectable cesium-137 levels in the samples ranged from 35.9 pci/kilogram to 489.0 pCi/kilogram.

As shown in Table 5-1, the cesium-137 levels in the soil samples were well within the range observed during preoperational and previous operational sampling.However, the cesium-137 levels measured in one of the soil samples, Station 23, exceeded the cesium-137 measured in the control sample, Station 9A, by more than a factor of 10.A strontium analysis was, therefore, performed on that sample, as required by the Site Certification Agreement.

The strontium concentration in the sample was below the detection level and below the range previously observed, as shown in Table 5-1.Aside from cesium-137, the only radionuclides detected in the samples were potassium-40, radium-226 and thorium-228.

These are part of the natural radioactivity typically found in soils.

The gamma spectrometry results for the soil samples are given in Tables A-8.1 and A-8.2 in Appendix A.No indication of impact of Plant 2 operations on the environment was evident in these results.5.5 River Sediment The results of gamma spectrometry of river sediment are presented in Tables A-9.1 and A-9.2 in Appendix A.Aside from the naturally-occurring radionuclides (potassium-40, radium-226 and thorium-228), only cesium-137 was detected downstream of the plant (Station 34).Cesium-137 was also detected in the control location (Station 33)sample.The cesium-137 concentrations upstream from the plant discharge point were 64.0 and 98.7 pCi/kilogram; the concentrations downstream from the discharge point were 198.0 and 221.0 pCi/kilogram.

These are consistent with the concentrations observed previously, as shown in Figure 5-14.Cesium-137 has been detected in preoperational samples and in samples taken since plant operation began.It has also been previously identified as a component of the Columbia River sediment originating from the operation of the old Hanford Reservation reactors."" 5.6 Fish The gamma spectrometry results of fish samples collected in the vicinity of the.Plant 2 discharge and at the control location on the Snake River are presented in Tables A-10.1 and A-10.2 of Appendix A.All results were below detection limits, except for potassium-40, a naturally-occurring radionuclide, and cesium-137.

The detectable cesium-137 levels for the fish taken from the Columbia River were low and within the range observed during the preoperational and previous operational periods.5.7 Milk All the results of iodine-131 analyses of milk samples collected during 1992 were less than detection limits.The routine iodine-131 in milk results are listed in Tables A-11.1 and A-11.2 of Appendix A.The gamma spectrometry results for the same milk samples are listed in Tables A-12.1 and A-12.2.All results for the indicator and control locations were less than the detection limits, except for potassium-40, which is naturally-occurring.

5.8 Garden Produce The gamma isotopic analysis results for all root, fruit and leafy vegetables were below detection limits.The results of all produce samples, including the apples collected from Station 91 and the cherries collected from Station 61, are listed in Tables A-13.1 through A-15.2 of Appendix A.5.9 S eci al Interest Sam les Three special'interest sampling locations were incorporated into the REMP during 1992.Discussions of the results from each of the three locations are given in the following sections.None of these locations, the storm drain, the Sanitary Waste Treatment Facility (SWTF), and the containerized storage area, were a part of the routine sampling 5-5 program for the,REHP until 1992.Until incorporated into the REHP, the sediment samples collected during previous years at the storm drain and SWTF were analyzed in the Support Services radiochemical laboratory in-house.The storm drain and SWTF sediment samples were analyzed wet, so the results were in terms of wet weight, instead of the dry weight concentrations determined by Teledyne.So direct-comparison of the wet sample results with the dried sample results is difficult since the percent solids can vary from sample to sample.This report includes only the samples collected during 1992.The data for containerized storage area, Station 118, consists of twenty-nine large metal storage containers holding the low pressure turbine rotor parts removed from the plant during the 1992 maintenance outage.'oil samples and ionization chamber readings were taken at Station 118.5.9.1 Storm Drain Pond Station 101 The storm drain pond is the drain field formed by the liquid discharges leaving Plant-2 via the storm drain pipe.The storm drain pond is located approximately 1500 feet east northeast of Plant-2, within the Plant-2 restricted area.The storm drain receives water from several sources, including building roof drains, the Service Building floor drain sump, the Diesel Generator Building floor dr ains, air handling unit drains, backwash effluent from gravity and carbon filters in the Service Buil'ding, and Turbine Building nonradioactive floor drains., The water released through the 18-inch diameter storm drain pipe flows into a 300-foot long earthen channel and then into the pond, which is approximately 100 feet in diameter.The pond is a shallow, unlined percolation/evaporation basin.Although not a part of the REHP sampling plan until early 1992, the storm drain sediment and water were periodically sampled by the REHP in the past.Periodically, cesium-137, cesium-134, cobalt-60 and zinc-65 were observed in the sediment and investigated, but the source(s)of the activity was never resolved.Then in February 1992, the storm drain became a part of the REMP sampling plan and the water, sediment, soil and vegetation samples collected there were sent to Teledyne~Isotopes for analysis.On April 29 and May 13, 1992, the REHP staff observed milky and red-colored water coming from the storm drain.A water sample collected at the storm drain outfall on April 29 contained detectable iodine-131'(12.6 pCi/liter).

A water sample collected on Hay 13 also contained detectable iodine-131 (21.1 pCi/liter), as well as cobalt-60 (124.7 pCi/liter), antimony-125 (20.8 pCi/liter), and cerium-141 (707 pCi/liter).

The tritium concentration measured in the water was 270,000 pCi/liter.

Problem Evaluation Request (PER)292-0531 was submitted to plant management on Hay 22.Because the iodine-131 and tritium levels in these samples resulted in the quarterly average concentrations for tritium and iodine-131 exceeding the NRC reporting levels, a Radiological Environmental Monitoring Program special report was submitted to the NRC on July 30, 1992.The sediment and water sampling frequency at the storm drain increased to daily, in order to characterize the extent of the release in April and May and to track the radioactivity levels.The radionuclide concentrations in the storm drain water on Hay 13 are compared to the NRC Reporting Levels, given in terms of quarterly averages, and the Washington State DOH investigation levels, given in terms of a single result, in Table 5-7.In order to characterize the impact of the radioactivity released on the storm drain sediment, a special set of surface sediment, samples'ere taken at six locations in 0'5-6 the channel and pond on Hay 22.Significant concentrations of cobalt-60, zinc-65, cesium-137, cesium-134, cerium-141 and manganese-54 were found at these locations.

A listing of the Hay 22 sample results and the results for sediment samples taken again at these locations on November 19 are given in Table 5-8.Although elevated levels of cobalt-60 and zinc-65 had periodically been observed in the past in the storm drain sediment, the levels were less than the concentrations following the Hay 13 incident.On July 9, core samples were taken at three locations to a depth of approximately five feet.The results of these core samples are presented in Table B-6.1 in Appendix B.Cobalt-60 was the most significant radionuclide found in these samples.The highest concentration of cobalt-60 was 2,410 pCi/kilogram, which was found at a depth of three feet at the storm drain pipe outfall.Samples at the other locations and depths contained much lower concentrations and some low concentrations of the other r adionuclides observed in surface samples.Cattail samples taken at the storm drain outfall on June 17 and September 16 showed detectable levels of cobalt-60, zinc-65, cesium-134, cesium-137, and manganese-54 (Tables 5-9 and B-8.1).An earlier cattail sample taken on Hay 22 and a grass sample taken on Harch 19 did not contain detectable concentrations of these radionuclides.

The root cause analysis resulting from PER 292-0531 concluded that the event occurred as a result of a transfer of water from a radioactive Turbine Building sump to a nonradioactive Turbine Building sump which was discharged to the storm drain.Corrective actions included evaluating potential leak paths from radioactive drain systems to nonradioactive systems, evaluating the sensitivity of monitoring equipment used on the floor drain sumps to determine whether it can be improved significantly, reporting the results of core samples used to characterize the storm drain radioactivity and exploring alternate methods of treating the high conductivity water historically discharged via the storm drain.In October an inspection by the NRC resulted in two notices of violation concerning the storm drain: (1)The Supply System disposed of radioactive liquid from a Turbine Building sump by discharge to the storm drain, a method not authorized by 10CFR20.301", (2)The Supply System had not maintained in the updated Final Safety Analysis Report (UFSAR)a description of the change to the facility resulting from the demonstration that nonradioactive Turbine Building sumps are now used as radioactive sumps and no written safety evaluation of this change was performed.

Following the Hay incident, tritium levels at the storm drain remained near the lower limit of detection until mid-June when a gradual.increase was observed.By September the tritium levels were approaching 30,000 pCi/liter, the NRC reporting level for a quarterly average concentration.

On November 6 PER 292-1255 was written to inform plant management that tritium levels at the storm drain continued to be significant.

Response to this PER included isolation of in-plant sources to the storm drain and the processing of water in the Turbine Building sumps through radwaste.On November 11, PER 292-1274 was submitted to alert plant management that the total radioactivity, particularly cobalt-60, in the storm drain sediment may exceed the 10CFR20 Appendix C values for designating a radioactive materials area.Response to this PER,included posting the storm drain area as a radioactive materials area, 5-7 making provisions for fencing the area and upgrading security surveillance of the area to prevent unauthorized access.Finally, because tritium levels both in the pond and at the outfall continued to be elevated, despite the isolation of the sources of input, PER 292-1339 was submitted on November 24.Response to this PER included performing a thorough walkdown to identify additional sources of input to the storm drain and continuing to isolate sources of contamination.

On November 25, a portable composite sampler was installed at the storm drain outfall.This sampler collects a 35-milliliter aliquot hourly and combines these into a daily composite.

Work will continue into 1993 to upgrade this sampling system to permit flow-proportional sampling.Snow samples were taken on December 18 at a location southwest of the cooling towers, in order to determine the tritium in the environment around the plant.The fresh snowfall at that location contained 410-430 pCi/liter (of water), which is above the detection level of 100 pCi/l.On the same day, a sample was taken from the water in cooling tower 2B and analyzed for tritium.The tritium concentration in that water was 460 pCi/liter.

As shown in Figure 5-15 and Table B-3.1 in Appendix B, the tritium levels continued to fluctuate from near detection level (100 pCi/liter) to 30,000 or 40,000 pCi/liter.

Then on December 31, the tritium concentration rose to 110,000 pCi/liter.

Investigation into the sources of the tritium revealed that meteorological conditions such as the cold temperatures and the wind direction were apparently causing the Turbine Building gaseous effluents containing tritium to condense on the adjacent building roofs and enter the storm drain.**An evaluation of the tritium results for the fourth quarter of 1992 indicated that the quarterly average tritium concentration was about 16,000 pCi/liter, which is well below the 30,000 pCi/liter average concentration requiring an NRC special report.5.9.2 Sanitar Waste Treatment Facilit Station 102 The Sanitary Waste Treatment Facility (SWTF), located approximately 0.3 mile south of Plant 2 processes the sanitary waste from Plant 2, the WNP-1 and WNP-4 sites and the Plant Support Facility (PSF).In 1991 a pipeline was installed from the Department of Energy's Fast Flux Test Facility (FFTF)to the Supply System SWTF to permit sanitary waste from FFTF to be processed there at some point in the future.The arrangements for this processing of FFTF wastes were never finalized, however.A valve was to have been installed at the FFTF end of the pipe to prevent the flow of wastes from FFTF.In November of 1991 EFSEC approved Resolution No.259"", which approved the introduction of FFTF wastes into the Supply System SWTF and outlined discharge standards and monitoring requirements.

Until April 1992, the SWTF sediment was sampled semiannually and analyzed in the Support Services radiation laboratory and the radionuclide concentrations were given in terms of wet weight.In April 1992, the sampling routine to satisfy Resolution No.259 was begun and the SWTF became a part of the REHP sampling plan.Water samples were taken at least monthly and sediment samples, which were not required by the resolution, were taken from the northern settling pond on a quarterly basis.Both the sediment and water~t*Tritium concentrations in water on the Service Building roof on December 25 and 26, for example, were 2,470,000 and 2,950,000 pCi/liter.

5-8

-samples were sent to Teledyne Isotopes for analysis, like all the other routine REAP samples.No detectable gamma activity was found in the April 1992 sediment sample or in the monthly water samples.In the July sediment sample however, cobalt-60 was detected in the sediment, so, the sampling frequency increased to monthly.In the next sediment sample taken August 12, both cobalt-60 and cesium-137 were detectable and present at concentrations far above levels that had been previously observed.Additional sampling was performed in September and October to determine the radionuclide levels in both stabilization/settling ponds.Water samples were also taken from both ponds and analyzed for tritium, as well as gamma emitters.When the results were received in late October, Problem Evaluation Request (PER)292-1206 was written, because the sediment in the north stabilization pond showed elevated levels of cobalt-60 (245-728 pCi/kilogram) and cesium-137 (169-248 pCi/kilogram) and the tritium concentrations (1400 and 1000 pCi/liter) in'he two ponds were at and above the state investigations level of 1000 pCi/liter.

The Washington State Department of Health (DOH)and the Nuclear Regulatory Commission (NRC)were notified of the results.Water samples taken from the aeration ponds, which had not received sanitary waste for several years did not contain detectable tritium or gamma emitters.Samples of water found in the pipeline on October 30 from FFTF, however contained 6,400 pCi/liter of tritium.On November 6, water and sludge samples were taken from the FFTF septic tank and ,sediment was taken from the drain field into which the FFTF septic tank had overflowed for several years.In addition, the pipeline leading from the septic tank to the SWTF was observed to have no valve to prevent FFTF wastes from entering the pipe.Tritium levels found in the septic tank water were 6,200 to 6,700 pCi/liter.

The septic tank sludge sample contained 400 pCi/kilogram of cobalt-60.

The soil taken from the drain field contained 359 pCi/kilogram of cobalt-60 and 284 pCi/kilogram of cesium-137.

Additional sampling at various SWTF locations indicated that water containing elevated tritium levels had been flowing into the facility since at least Hay 1992.Water samples taken before that were not available for reanalysis so the exact period of time the FFTF waste had been entering the SWTF could not be determined.

Samples of soil/sludge taken from a percolation bed, the dosing pond and the nearby lift station overflow basin showed no detectable gamma activity, indicating that the present gamma activity found in the stabilization pond sediment had not been present long enough to impact the levels of radioactivity.

in the beds to which settling pond discharges are made.The root cause analysis report concerning this incident concluded that the radioactivity found in the stabilization ponds most likely originated at the FFTF and that the"failure to perform detailed testing of the FFTF sewage effluent prior to entering into an agreement to install the pipeline between FFTF and the SWTF was a basic reason for the incident to occur." To prevent recurrence, a concrete plug was installed in the pipeline from FFTF.The results of all the samples taken at the SWTF during 1992 are given in Appendix B.Graphs of the sediment concentrations of cesium-137 and cobalt-60 from 1987 through 1992 are presented in Figure 5-16.A drawing of the facility showing the sample locations and the most significant analytical results from the investigation into the detectable sediment and water radioactivity is presented in Figure 5-17.1992 tritium concentrations in the headworks and the north stabilization pond are presented in Figure 5-18.5-9 O.5.9.3 Containerized Stora e Area Station 118 Soil samples taken at Station 118 before and after storage of the low pressure turbine rotor parts contained no detectable radioactivity except that from naturally-occurring radionuclides, such as potassium-40 and radium-226.

In Nay, a small amount of water leaked from the storage container at location N at Station 118.The soil sample taken at the location contained no detectable radioactivity.

All the soil results for Station 118 are contained in Table B 19.1 and B 19.2 in Appendix B.5-10 TABLE 5-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAH COMPARATIVE

The adequacy of their quality assurance program is also assessed during the audits.Intercomparison programs, which involve the comparison of Supply System analytical results for samples containing known concentrations of various radionuclides with the known values and with the results reported by other monitoring programs, are also a major component of the quality assurance activities of the REHP.The program participates in the Environmental Protection Agency (EPA)and Environmental Measurements Laboratory (EML)intercomparison programs.It also participates in local and regional intercomparison studies.The following sections summarize the quality assurance and quality control aspects of the TLD and analytical components of the REHP.6.1 ualit Control For the Su l S stem Environmental TLD Pro ram The guality Control Program for the environmental TLD preparation, processing and evaluation is described in Figures 6-1 and 6-2.gA dosimeters, which are annealed just prior to being given a known exposure to 100 mR of cesium-137 gamma radiation and processed among the field dosimeters, serve as indicators that the readout, calibration and evaluation of the field dosimeters were properly performed.

The number of gA dosimeters used during each processing is generally 10%of the number of field dosimeters.

Since 1987 the same gA dosimeters have been used repeatedly throughout the year in order to track their sensitivity and to provide consistency from run to run.If the mean gA dosimeter results are greater than+5%(or 5 mR)of the given exposure, an investigation into the source of the discrepancy is initiated.

Evaluation of the 1992 gA dosimeter results indicated only small biases for the four quarters.Control dosimeters (trip controls)are used for each set of field dosimeters to monitor the contribution of the exposure received by the field TLDs while in transit.The radiation background in the storage area is also monitored by a separate set of control dosimeters (building controls).

If the trip control results are significantly greater than the building control results, the difference between the two is subtracted from the field dosimeters.

Spiked dosimeters, which are exposed to known levels of radiation below the 100 mR given to the gA dosimeters, were processed with the field dosimeters during each run to verify the accuracy of the environmental TLD evaluations.

The results of these audit dosimeters processed during 1992 are presented in Table 6-1.All results were well within a5%of the given exposure.6-1 During each environmental TLD processing, individual calibration factors are determined for each TLD by exposing the TLDs to 100 mR from an encapsulated cesium-137 source.The calibration exposure is determined from the exposure duration and the assessed source strength at 55 centimeters.

As a quality control check for each calibration exposure, an HIST-traceable ionization chamber is also used to determine the calibration exposure.If the ionization chamber measurement does not agree with the calibration exposure to within+5%of the calculated value, an investigation is performed into the discrepancy and the TLD calibration is repeated, if necessary.

6.2 ualit Control For the Anal tical Pro ram guality control for the analytical program involves two components:

the quality control activities performed by the Supply System and the quality control program of the analytical contractor, Teledyne Isotopes.Both of these components are described in the following sections.6.2.1 Supply System guality Control Activities The Supply System has participated in the U.S.Department of Energy Environmental Heasurements Laboratory (EHL)guality Assessment Program since 1987.The Supply System results for the samples sent out in Harch and September of 1992 are listed on Table 6-2.The Teledyne cesium-137 results showed the slight high bias (20-30%)in some media that has been evident in previous years.In general, however, the Teledyne results agreed with the EHL values.In addition to participating in the EHL Intercomparison Program, the Supply System participates in the Environmental Radiation guality Assurance Task Force of the Pacific Northwest (gATF)intercomparison program.During October 1992 three types of samples, groundwater from the Hanford Site, sediment from Bull Run Lake in Oregon and an EPA reference water sample, were distributed to participants.

The Supply System results for the gATF samples are given in Table 6-3 along with those for the other participants.

Duplicate samples were also submitted to Teledyne for analysis during 1992.These duplicates consisted of two sets of milk samples and one set of air filters from EHL.The milk duplicates were marked Station 37 and were submitted for analysis at the same time as the milk samples from Station 36.6.2.2 Teledyne Isotopes guality Control Program The goal of the quality control program at Teledyne Isotopes is to produce analytical results which are accurate, precise and supported by adequate documentation.

The program is based on the requirements of IOCFR50, Appendix B, Regulatory Guide 4.15 and the program, as described in Teledyne's equality Assurance Hanual IWL-0032-395 and guality Control Hanual IWL-0032-365.

All measuring equipment is calibrated for efficiency at least annually using standard reference material traceable to the National Institute of Standards and Technology (NIST).For alpha and beta counting, check sources are prepared and counted every week day except holidays.Control charts are maintained with 0 three-sigma limits specified.

Backgrounds are usually measured at least once per week.6-2 The efficiency of the gamma spectrometers is calibrated annually with a NIST traceable standard reference material selected to cover the energy range of the nuclides to be monitored and to include all of the geometries measured.Backgrounds are determined every other week and check sources are counted weekly.The energy resolution and efficiency are plotted at two energy levels (125.1 and 1274.4 kev)on charts and held within three-sigma control limits.The efficiency of the tritium gas counters was determined every month by counting a NIST traceable standard which had been diluted in a known amount of distilled water so that the activity level loaded into the counter is sufficient to provide good counting statistics but not so active as to contaminate the counter.If the efficiency measurement does not agree within two standard deviations of the average of the previous six measurements, corrective action is taken.The background of each counter is measured after each sample measurement.

A control chart is maintained for the background measurements as a stability check.This procedure is described in PRO-052-50"Calibration of Gas Counters for Tritium Analysis".

During the month of August the tritium gas counters were removed from service.The Supply System then approved use of liquid scintillation method of tritium analysis.Included in the tables for the Teledyne gA blanks and spikes is data for tritium analysis by liquid scintillation counting.Control of sample identity is maintained by the assignment of a unique five-digit number which is maintained throughout the sample's history from sample receipt, log-in number assignment and designation of analysis to reporting the final analytical result.'esides ensuring sample accountability, Teledyne procedures also ensure the maintenance of sample integrity by controlling sample storage and taking steps to prevent contamination of samples.Results are reviewed for reasonableness before being entered into the data system.Any results which are suspect, i.e., which are higher or lower than results in the past, are returned to the laboratory for recount.If a longer count, decay check, recount on another system or recalculation does not give acceptable results based on experience, a new aliquot is analyzed.The complete information about the sample is contained on the worksheets accompanying the sample results.No deviations from written procedures occurred during 1992.Summaries of the results of internal blanks and spiked samples used for quality control are presented in Tables 6-5 and 6-6.A summary of the EPA cross-check sample results is presented in Table C-I of Appendix C.Iodine-131 Cartrid es One blank charcoal cartridge was analyzed on a weekly basis with each set of cartridges, for a total of fifty-three blanks.The average result was 6.4+7.9E-Ol pCi per cartridge.

This was calculated without considering detection limits.Gross-Beta

-Filters One blank filter was measured with each set of filters analyzed.Fifty-three blanks were counted.The average activity in total pCi was 9.3+1.8E-Ol, which indicated a relatively stable background for the filters, including the background of the gross beta proportional counters.6-3 I-131-Mi1 k 0 A blank milk was analyzed with each group of samples analyzed.The results showed that there was no contamination in the laboratory or counting area.The measurements of the blank samples (Table 6-5)indicated that ther e was no bias on the low background counters.The average activity for twenty samples in 1992 was 2.615.3E-Ol pCi/liter.

This was calculated from quality control samples, without considering detection limits.A total of fifty-three in-house blank milk samples were processed throughout 1992.The average result was 3.915.1 E-02 pCi/liter.

Sr-90-Milk and Mater~'lank water samples were analyzed on a weekly basis.The average result of fifty-three blank water samples was 1.522.2E-Ol pCi/liter.

Fifty-three spiked water samples were analyzed.The average result was 3.710.2E+Ol pCi/liter, compared with a spike level of 4.010.6E<01 pCi/liter.

A total of twenty-three milk samples were spiked to a level of 4.0+0.6E+Ol pCi/liter.

The average activity determined for the spikes was 3.6t0.4E+Ol pCi/liter.

These results were within the limits specified by the EPA Intercomparison Studies Program.A total of twenty-four blank milk samples were analyzed, with an average activity of 1.410.5E+00 pCi/liter of strontium-90.

Gross Beta-Water Fifty-three blanks were prepared from distilled water.The average result, without considering detection limits, was 2.7+1.7E-Ol pCi/liter.

No contamination was indicated and the background level was low and stable.During 1992 fifty-three gross beta spike samples were analyzed during 1992, with a spike level of 2.2i 0.5 pCi/liter.

The average result was 2.211.7E+Ol pCi/liter.

This was well within the guidelines outlined in Table 2 of EPA-600/4-81-004.

Tritium in Water Thirty-six blank samples were analyzed by gas counting.The average result was-5.017.8E-01 pCi/liter.

Thirty-seven tritium samples with a spike level of 1.5i0.2E+03 pCi/liter were analyzed by gas counting during 1992.The average result was 1.4+0.1E+03 pCi/liter.

Fifty-three blank samples were analyzed by liquid scintillation.

The average result without considering detection limits was 3.213.0E+02 pCi/liter.

Fifty-three tritium samples with a spike level of 1.510.2E+04 pCi/liter were analyzed by liquid scintillation during 1992.The average result was 1.4+0.1E+04 pCi/liter.

Gamma S ectrosco A blank water sample was analyzed on a weekly basis in the gamma spectroscopy laboratory.

All nuclides were less than the normal level of detection, indicating no contamination.

Spike samples were measured weekly using the Eu-154 peak at 1274.5 KeV.The average activity of fourteen measurements was 1.4410.02E+05 pCi/liter, compared with a spike level of 1.40+0.20E+05 pCi/liter.

No corrective action necessary.(e)All lab data sheets were verified for accuracy.Three different detectors were used with aliquot ingrowth times of 9 and 19 days.Results ranged from 4 to 6 pCi/1.Dilution error has been determined to be the probable cause for the deviation from the spike value.Internal biweekly spike analyses have been in control.Corrective action includes implementation of a dilution form to record aliquot and solvent volumes.Entries will be made by the technician and reviewed by the supervisor.(f)An investigation is being conducted; the results will be available shortly.(g)There is no apparent reason for the high cesium-137 results.The sample geometry and detector efficiencies were verified to be correct.The Total K and iodine-131 by gamma spectroscopy were in good agreement with EPA values.There is no trend and results were within i3 sigma so no action taken.C-5 80 60 O 40 20 0 20 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl k 3 Sigma 4 EPA 2 3 Sigma FIGURE C-I EPA CROSS CHECK PROGRAM-S ALPHA IN AIR PARTICULATES 160 140 120 100 0$~O 80 60 40 20 1981 1982~1983 1984 1985'1986 1987 1988 1989 1990 1991 1992 1993'8/25/89 EPA test invalid.Tl 2 3 Sigma 4 EPA t 3 Sigma FIGURE C-2 EPA CROSS CHECK PROGRAM-GROSS BETA IN AIR PARTICULATES CD CJl I Pl M I Ol LLI C5 U I CO CD CC O C/l CA CD CZ'.Lal Ol CO Cl)CI C4 al O CQ tedlagogC-8 80 60 O 40 l0 0 20 20 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl a 3 sigma 4 EPA a 3 sigma FIGURE C-4 EPA CROSS CHECK PROGRAM-CESIUM-137 IN AIR PARTICULATES 80 O 40 0 0 20 1081 1082 108$1084 1985'l98d 1987 108S 1089 1000 1991 1002 1092 Tl 2 3 sigma 0 EPA 23 sigma Strontium-89 I 4 40 O CL~20 1081 1082 1083 1084 1985 1088 1087 1088 1980 1900 1001 1002 1003 TI 2 3 sigma<EPA 23 sigma Strontium-90 FIGURE C-5 EPA CROSS CHECK PROGRAM-STRONTIUM IN MILK C-10 140 120 I 80 60 40 20 20 1981 1982'l 983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl f 3 sigma 4 EPA i3 sigma FIGURE C-6 EPA CROSS CHECK PROGRAM-IODINE-131 IN NII.K 80 Q 6O 0 a 40 20 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Tl 13sigma 4 EPA 13sigmaFIGURE C-7 EPA CROSS CHECK PROG-CESIUM-137 IN MILK 140 120 L 80 0 60 40 20-20 1984 1985 198e 1987 1988 1989 1990 1991 1992 1993 Tl 2 3 Sigma 4 EPA X 3 Sigma FIGURE C-8 EPA CROSS CHECK PROGRAM-GROSS ALPHA IN WATER 220 200 180 160 140 Q 120 0 100 80 60 40 20 0-20 1987 1988 1989 1990 1991 1992 1993 Ti i 3 sigma 4 EPA t 3 sigma1 FIGURE C-9 EPA CROSS CHECK PROGR GROSS BETA IN MATER
