Table 5-1 presents the means and ranges of selected 1998 results for each type of sample collected and Table 5-3 provides a summaiy of detectable results.The means and ranges of the preoperational and the previous operational data are also included in the table for comparison.

The data tables of 1998 results comprise a separate volume that is available to interested parties.The data for the prcoperational period and the first six months of 1984 included"less than" (()designations for icsults below the actual LLD, the contractual LLD, or the two-sigma erior, depending upon the convention employed by the analytical contractor.

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

Since the primary focus of the REMP is to deteimine whether Plant 2 operations had an impact on the environment, the 1998 results are compared in this rcport to the icsults during the prcoperational period and the results obtained during the previous years of Plant 2 operation.

They are also compared to state and federal regulatory limits.Because of the use of"less than" values, mther 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 1998 measurements relative to previous measurements must bear this in mind.Some of the parameters considered in the evaluations discussed in this icport are the means, ranges and standard deviations or standard errors of the results.Comparative plots and ficquency distributions of the data are some of the tools that have been employed in the interpretation of the 1998 REMP data.The 1998 analytical icsults for the REMP sampling locations established since the picoperational period ate very similar to the results reported for previous years.The 1998 annual and quarterly TLD zcsults were also very much like those observed previously.

No significant trends indicating an enviionmental impact or unexpected change in the environmental concentrations or exposure rates at REMP monitoring stations were observed.5-1 1998 REMP ANNUAL REPORT

Variations in the soil and underlying rock composition most likely account for localized differences such as shown in the TLD results for Station 46.The quarterly mean of the four quarterly results for Station 46 was 0.30 mR/day, with a range of 0.27 mR/day to 0.31 mR/day.Frequency distribution plots of the 1998 quarterly TLD Iesults are pIesented in Figure 5-4.The plots were varied slightly from quarter to quarter, with 0.24 mR/day being the most frequent result, followed by 0.25 mR/day, 0.23 mR/day and 0.26 mR/day.The most frequent result for the period 1984 to 1997 was 0.26 mR/day, followed by 0.25 mR/day, 0.27 mR/day and 0.24 mR/day.The frequency distributions for the previous operational TLD results an: shown in Figure 5-5.A comparison of the 1998 annual and mean quarterly TLD result is pIesented in Table 5-6.The 1998 annual TLD Iesults ate generally 5-10%lower than the mean quarterly Iesults because of signal fade.This defference 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 IeSultS.5-3 1998 REMP ANNUAL REPORT 70 65 1998 MEAN 0242 mR/DAY TOTAL OCCURRENCES

Particulate/Iodine 'Ihe 1998 mean weekly gross beta on particulate filter icsults for indicator stations near (within 3 miles)Plant 2 are plotted in Figure 5-6.'Ihe yoss beta in air xcsults for 1998 were within the ranges observed during the picoperational period and during previous operational periods, as shown in Table 5-1.In Figure 5-7, the similarity between melts from near-plant locations and those from remote locations can be seen.The control location (Station 9A)insults 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.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, beiyHium-7 and potassium-40, at levels above detection limits at indicator locations and the control location.All iodine-131 in air results for 1998 were less than the 0.02 picocuries/cubic meter (pCi/m')LLD.SEEKS l9 75 R)R 1985 ARE NOr INCu)DED IN MEAN DUE TQ IEGII BIAS CAUSED BY CNERNCBYL Io all La aIO~0.09 g aco$ao7 IS aOO 8~ao)aol I 5 5 7 9 II 1515)7)9)I 2)2527%515))557)9 4I 4)454749 5l IRUVAVC I)8597 4$AVERAGE199$ Figure 5-6 1985-97 Weekly Hi/Low/Mean vs.1998 Weekly Mean Gross Beta in Air-Near Plant Stations NOIR'O'EEKS l)-2)fOR I 924 ARE NO7 INCEUDED IN MEAN DUE TO BIO)I BIAS CAUSED BY aKRNOBYL 4.22 w~a)I o a'o$aot 2$ao)o aot OOI I l S I 7 II D 1$27 It II 2l)$27 lt ll)))S)7)t~I 4l 4$47 4t SI WEEK NlfLO/AVCI)9597 ~AVERAGE)992 Figure 5-7 1985-97 Weekly Hi/Low/Mean vs.1998 Weekly Mean Gross Beta in Air-Remote Stations No evidence of any impact of plant operations on the environment was apparent in the particulate filter and charcoal cartridge results for 1998.5-5 1998 REMP ANNUAL REPORT

The cobalt-60 was measured at 6.2 pCi/I, well below the NRC reporting level of 300 pCi/l.5.4 Soil Gamma spectrometry performed on soil samples in 1998 indicated a range of cesium-137 Aom 23 picocuries/kilogram (pCi/kg)to 166 pCi/kg at the indicator stations and a result of 79 pCi/kg at the consol station.As shown in Table 5-1, the cesium-137 levels in the soil samples were well within 5-7 199$REMP ANNUAL REPORT the range observed during preoperational and previous operational sampling.The gamma spectrometry results for the soil samples did not indicate any impact from Plant 2 operations on the environment. No stxontium analysis was xequixcd in 1998.Aside from cesium-137, the only radionuclides detected in the samples were potassium-40, radium-226 and thorium-228. These axe part of the natural radioactivity typically found in soils.5.5 River Sediment The results of gamma spectxometxy of river sediment indicated that aside fxom the naturally occurring radionuclides (potassium-40, radium-226 and thorium-228), cobalt-60 and cesium-137 were detected downstxcam of the plant (Station 34).Cesium-137 was also detected in the upstream control sample (Station 33).The cesium-137 concentrations in the upstream samples were 42'pCi/kg and 60 pCi/kg dxy weight.The concentrations of cesium-137 in the downstxeam samples were 194 pCi/kg and 337 pCi/kg dry weight.Cobalt-60 levels in the two downstream samples were 20 pCi/kg and 22 pCi/kg dry weight, Both cobalt-60 and cesium-137 have been detected in similar quantities in pamperational samples and operational samples.They have also been previously identified as components of the Columbia River sediment originating from the operation of the old Hanfoxd Reservation reactors."" 5.6 Hsh The gamma spectrometry xcsults of fish samples collected in the vicinity of the Plant 2 discharge and at the contxol location on the Snake River were below detection limits, except for potassium-40, a naturally-occurring radionuclide. 5.7 Milk There was one detectable iodine-131 result in 1998.The result of 0.64 pCi/1 was found in the November sample taken at Station 64 and is just above the detection level for this nuclide.The iodine-131 result from the other downwind dairy was below the detection limit.An investigation of plant effluents determined it was not an effect from the plant.All gamma spectxometxy milk sample results for the indicator and control locations were less than the detection limits, except for potassium-40, which is naturally occurring. Because of the loss of the control dairy, it was decided to use the garden produce as a substitute while another suitable dairy was located.No dairy in the area of the control was located that didn'at least use feed grown downwind of the plant as supplemental feed.In August, the REMP began collecting samples of feed grown by the owners of the dairy at Station 9.No radionuclides were detected other than the naturally occurring beryllium-7 and potassium-40. 1998 REMP ANNUAL REPORT 5-8

5.8 Garden

Produce The gamma isotopic analysis icsults for all root, fruit and leafy vegetables collected in 1998 were below detection limits other than potassium-40, which occurs naturally.

5.9 Special

Interest Stations The storm drain pond, Sanitaiy Waste Treatment Facility (SWTF)and the containerized storage area were incorporated into the routine sampling schedule in 1992.The cooling tower sediment disposal area was added in 1995.Thermoluminescent dosimeters were placed around the spray pond drainfield (Station 120)in June 1995.Discussions of the icsults from each of the locations aic given in the following sections.Until incorporated into the REMP, the sediment samples collected during previous years at the storm drain and SWTF were analyzed by the Supply System.The storm drain and SWTF sediment samples were analyzed wet, so the icsults were in terms of wet weight instead of the dry weight concentrations determined by Teledyne.Consequently, direct comparison of the wet sample icsults with the dried sample icsults is difficult since the peicent solids can vary from sample to sample.5.9.1 Storm Drain Pond (Station 101)The storm drain pond is located approximately 1500 feet northeast of Plant 2.Water is conveyed to the pond via a 18-inch diameter pipe which discharges into a 300-foot long earthen channel that leads to a 100-foot diameter pond.The pond is a shallow, unlined percolation/evaporation basin.REMP personnel collected water, sediment, soil and vegetation samples at the outfall during 1998.Monthly water grab samples and sediment samples were taken&om the pond area beginning in July of 1994 and were discontinued in July 1996.At the outfall, an automatic sampler collected flow proportional composite water samples.Sediment sampling at the outfall was changed from monthly to biannually in July of 1996.Vegetation was sampled annually near the outfall.Tritium was the only isotope detected during 1998.Figure 5-12 shows the monthly averages for 1992 thmugh 1998.The range for positive tritium results at the outfall was from 160 pCi/1 to 3700 pCi/1 and averaged 738 pCi/I.Detectable gross beta activity at the outfall averaged 4.4 pCi/1 with a range of 2.6 to 9.3 pCi/l.In June, an accidental actuation of the fire protection system caused the rupture of a cast iron valve, icsulting in flooding of a stairwell in the Reactor Building.Approximately 160,000 gallons of water was discharged into the stairwell. A sample of the water in the stairwell was taken and counted, per procedure, to free release LLDs by the Plant Chemistry laboratory. There was no detectable activity in this sample.Approximately 17,000 gallons of water was pumped from the stairwell to the storm drain pond when a second sample indicated a possibility of cobalt-60 being present.Pumping activities were suspended. The flow-proportional composite sampler at the outfall collected 171 ml of sample, which upon analysis at Teledyne, confirmed that there was no detectable cobalt-60 present.5-9 1998 REMP ANNUAL REPORT 00 I 1.04+0)5 P I.04+01 JAN FSB O1 991~1991 O1996 JUN JUI MONTH O199S O1 996 81999 1994 Figure 5-12 Average Monthly Tritium at Storm Drain Outfall-1992-98 Sediment at ST101 was sampled biannually at the outfall.In the sediment samples, cobalt-60 and cesium-137 were detected, along with the natural-occurring nuclides potassium-40, radium-226 and thorium-228. Detectable cobalt-60 averaged 174 pCi/kg dry and ranged from 140 pCi/kg dry to 207 pCi/kg dry.The detectable cesium-137 ranged from 38 pCi/kg dry to 44 pCi/kg dry and averaged 41 pCi/kg dry All six soil samples, taken on the east and west banks, had detectable amounts of cesium-137 in them.The natural radionuclides of beryllium-7 potassium-40, radium-226 and thorium-228 were also detected.Cesium-137 averaged 33 pCi/kg and ranged from 30 pCi/kg to 37 pCi/kg.These results an: within the ranges observed in previous years.In the annual vegetation sample taken in the stieam, no detectable radionuclides were found other than potassium-40, which occurs naturally.

5.9.2 Sanitary

Waste Treatment Facility (Station 102)The Sanitary Waste Treatment Facility (SWTF), located approximately 0,4 mile south-southeast of Plant 2, processes the sanitary waste from Plant 2, the WNP-1 and WNP-4 sites, the Plant Support Facility (PSF)and the Department of Energy's 400 Area (beginning April, 1997).Discharge standmds and monitoring requirements for the SWTF are established in EFSEC Resolution No.259"".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.Gross beta icsults for wastewater sampled prior to discharge to the percolation beds averaged 37 pCi/l and ranged Rom 32 pCi/l to 41 pCi/1.An investigation in 1994 into the source of the gross beta indicated potassium', a natural isotope, was the major contributor. Other contributors to the beta appear to be natural isotopes and no fission or activation products were detected that would 1998 REMP ANNUAL REPORT 5-10 indicate Plant 2 as a source.Monthly composite water samples of the 400 Abaca effluent had gross beta results ranging fiom 17 pCi/1 to 41 pCi/1 and averaging 29 pCi/l.Prior to discharge samples and 400 Area effluent samples were also analyzed for gmss alpha.There were no detectable gross alpha results for 1998.Tritium results at the headworks (ST.102B)continued to increase due to the influx of FFTF effluent.The mean at the headworks increased from 466 pCi/1 to 1342 pCi/1.From May until August, tritium levels at the FFTF sewer line (ST.102A)averaged 15000 pCi/1.This was due to FFTF drawing water from another aquifer, known to have tritium levels of approximately 20000 pCi/I, while maintenance was performed on the main pump.The annual average for tritium at ST.102A was 8008 pCi/1 and ranged from 3800 pCi/1 to 20000 pCi/1.Tritium in the prior to discharge samples (ST.102C)averaged 803 pCi/1 and ranged fiom 480 pCi/1 to 1100 pCi/1.Water samples taken fiom the north stabilization pond (ST.102D)ranged fiom 670 pCi/1 to 1200 pCi/1 and average 935 pCi/1 while the south stabilization pond (ST.102E)had a mean of 925 pCi/1 and a range of 550 pCi/1 to 1300 pCi/l.Gamma analysis of sediment samples collected from the north stabilization pond revealed detectable quantities of cobalt-60 and cesium-137 in addition to naturally occurring nuclides.Detectable cobalt-60 ranged fmm 164 pCi/kg dry weight to 2110 pCi/kg diy weight.Cesium-137 results ranged from 72 pCi/kg dry weight to 132 pCi/kg diy weight.After the higher cobalt-60 result was received, a second sample&om the sample area was taken.The cobalt-60 and cesium 137 results for this sample were below the detection limits.5.9.3 Containerized Storage Area (Station 118)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, Soil samples and ionization chamber readings were taken at Station 118.Beginning in September 1994, samples from different areas were composited and sent to Teledyne Brown for analysis Soil samples taken at Station 118 before the storage'of the low-picssure turbine rotor parts contained no detectable radioactivity except that from naturally occurring radionuclides, such as potassium-40 and radium-226. No detectable nuclides, other than those that are naturally occurring, were found in 1998.5.9.4 Cooling Tower Sediment Disposal Area (Station 119)'On May 8, 1995, EFSEC approved Resolution No.278"@that authorized the onsite disposal of cooling tower sediments containing low levels of radionuclides. This area is located just south of the cooling towers.According to Resolution No.278, the REIMP is to monitor the aica's direct radiation exposure rate with annual pressurized ion chamber measurements. Direct radiation dose is measum1 by quarterly and annual TLDs and a dry composite sediment sample is taken from the disposal cell within thirty days following each cleaning to confirm that the disposal criteria outlined in the resolution have not been exceeded.5-11 1998 REMP ANNUAL REPORT An estimated total of 41 cubic yards of material was disposed of during the 1998 cleaning.Using the volume and an average measured dry density of 1.4 g/cm', along with the activity, it is calculated that the following quantities of nuclides were placed in the disposal area: Cobalt-60 Manganese-54 Zinc-65 Cesium-134 1.85E-06 curies 4.56E-07 curies 9.13E-08 curies'1.90E-06 curies Cesium-137 1.00E-05 curies Qf the above nuclides, only cobalt-60 and cesium-137 were above detection levels.The cobalt-60 cult was 42 pCi/kg dry.The cesium-137 result was 228 pCi/kg dry.Since the results for manganese-54, zinc-65 and cesium-134 were lower than the detection limit, the calculated quantities disposed of those nuclides are estimates of maximum possible concentration. Measurements of direct radiation were taken using TLDs and a Reuter Stokes pressurized ion chamber.The TLDs were collected quarterly and annually.Two locations were used, one next to the collection area (ST.119B)and the other approximately 100 yards to the east as the control (ST.119-Control). The mean quarterly TLD result for ST.119B was 0.25 mR/day and ST.119-Control had a mean quarterly result of 0.24 mR/day.The annual TLD results were 0.22 mR/day for ST.119B and 0.23 for ST.119-Control. The pressurized ion chamber readings were taken monthly during 1998.The readings remained consistent throughout the year, with a high mean of 0.0102 mR/hr in March with the plant at 100%power to a low mean of 0.0091 mR/hr in April, with the plant shutdown.The average for the year was 0.0097 mR/hr.5.10 Spray Pond Drain Field (Station 120)Sediment&om spray pond cleanings had been discharge) to a trench located approximately 500 feet south of the spray ponds.In 1995, soil samples taken in, the trcnch indicated detectable amounts of cesium-137 and cobalt-60. In 1996.the deposited sediment was removed to a disposal cell south of the cooling towers.The trencli has continual to be used as the discharge location for spray pond filter backwash water.In 1997, the decision was made to remove the west TLD station inside the trench, and the control TLD station on the south bank.The Station I l9 Control TLD would also act as the control location for Station 120.In 1998, the niean for the quarterly TLD inside the trench was 0.25 mR/day.The quarterly mean for the contrvl location was 0.24 mR/day.The annual results were 0.23 mR/day for both locations. Soil samples were taken in March and October of 1998.The samples are composites, taken from several areas inside the trench.These continued to show that no new radionuclides had been deposited in the trench since the previously deposited sediment was relocated in 1996.Along with the naturally occurring nuclides of beryllium-7, potassium-40, radium-226 and thorium-228, the 1998 REMP ANNVAL REPORT 5-12 only other detectable nuclide was cobalt-60 and cesium-137. The cobalt-60 results were 16 pCi/kg and 61 pCi/kg and the one detectable cesium-137 result was 21 pCi/kg.The cobalt-60 results were far below the pre-cleaning result of 6880 pCi/kg and comparable to results of samples taken immediately after the sediment had been removed in August of 1996.5.11 1998 Sample Deviations Air sampler outages made up the majority of sample deviations for 1998.Problems ranged from pump failure to power outages.Qf the three water sample deviations, one was due to the plant refueling outage and another to an outage of the water source.Deviations are listed in Table 5-2.5-13 1998 REMP ANNUAL REPORT TABLE 5-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM COMPARITIVE

6.0 UALITY

ASSURANCE AND UALITY CONTROL The REMP is designed to meet the quality assurance and quality control criteria of Regulatory Guide 4.15"'.To accomplish this, the REMP requires that its analytical contractors meet these criteria also.In<epth audits are performed of the REMP records and activities and the records and activities of its support organizations at least annually by the Supply System Quality Assurance group.Quality assurance and technical audits of the analytical contractor (Teledyne Brown Engineering) are also conducted periodically to verify their compliance to regulatory and contractual requirements. The adequacy of their quality assurance program is also assessed during the audits.Intercomparison programs, which involve the comparison of Supply System analytical melts of samples containing known concentrations of various radionuclides, to the known values and also with the icsults reported by other monitoring programs, are a major component of the quality assurance activities of the REMP.The program participates in the Environmental Protection Agency (EPA)and Environmental Measurements Laboratoiy (EML)inteicomparison 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 REIMP.6.1 Quality Control For the Supply System Environmental TLD Program The Quality Control Program includes the pieparation, processing and evaluation of environmental TLDs.To begin with, all environmental TLDs, including controls, which are to be used in the same quarter (or year for annuals), are annealed at the same time.This allows for uniform accumulation of and cornxtion for background radiation. From the time the TLDs an: annealed to the time they are placed in the field, they are stool and transported together.Once the field TLDs are collected, they are again stored together with the controls until processed. Reader QC dosimeters aa: prepared by the TLD processor and serve as indicators that the invader calibration is satisfactory and that the TLDs were pmcessed correctly. These TLDs are annealed just prior to being given a known exposure (typically 100 mR)to'"Cs and processed among the field dosimeters. The number of QA dosimeters used during each pmcessing is generally 10%of the number of field dosimeters. If the mean icader QC dosimeter results vary by more than+5%from the given exposure, the processor is contacted and an investigation into the source of the disciepancy is initiated. Evaluation of the 1998 reader QC dosimeter results indicated satisfactory agnmment for all four quarters and the annual processing results.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 monitor by a separate set of control dosimeters (building controls). If the trip control results are greater tlian the building control results, the difference between the two is subtracted fiom the field dosimeters. 6-1 1998 REMP ANNUAL REPORT Spiked dosimeters, which are exposed by the Supply System, are irradiated 25 mR cesium-137 for quarterly dosimeters or 85 mR for annual dosimeters. These spiked dosimeters aa: also processed with the field dosimeters during each run to verify the accuracy and consistency of the environmental TLD evaluations. All results were within,J5% of the known exposure and aie piovided in Table 6-1.Extra sets of control dosimeters, known as zero dose dosimeters, are also included with the field dosimeters for processing. These zero dose TLDs are stored in a shielded container throughout the quarter (or year for annuals)and are used as an additional indication of reader performance. These TLDs may also be used as substitutes if a field TLD is lost.6.2 Quality Control For the Analytical Program Quality control for the analytical program involves two components: the quality contml activities performed by the Supply System and the quality control program of the analytical contractor, Teledyne Brown Engineering. Both of these components are described in the following sections.6.2.1 Supply System Quality Control Activities The Supply System has participated in the U.S.Department of Energy's Environmental Measurements Laboratory (EML)Quality Assessment Program since 1987.In general, the Teledyne Brown icsults ayeed with the EML values as seen in Table 6-2.All results were either acceptable or acceptable with warning.Duplicate samples were submitted to Teledyne Brown for analysis during 1998.These duplicates consisted of two sets of milk samples and one set of air filters from EML.The milk duplicates were marked Station 37 and were submitted for analysis at the same time as the milk samples fiom Station 36.6.2.2 Teledyne Brown Engineering Quality Control Program The goal of the quality control program at Teledyne Brown Engineering -Envimnmental Services is to pioduce analytical icsults which are accurate, precise and supported by adequate documentation. The program is based on the requirements of 10CFR50, Appendix B, Nuclear Regulatory Guide 4.15 and the program, as described in Teledyne's Quality Assurance Manual (IWI 0032-395)and Quality Control Manual (IWL-0032-365). All measuring equipment is calibrated for efficiency at least annually using standi reference material traceable to the National Institute of Standards and Technology (NIST).For alpha and beta counting, check sources are prepared and counted each weekday the counter is in use.Control charts aic maintained with thine-sigma limits specified. Backgiounds are usually measured at least once per week."'998 REMP ANNUAL REPORT 6-2 The gamma spectrometers are calibrated annually with a NIST-traceable standard reference material selected to cover the energy range of the nuclides to be monitor for all of the geometries measured.Backgrounds are determined every other week and check sources are counted weekly.The energy resolution and efficiency an: plotted at two energy levels (59.5 and 1332 KeV)and held within three-sigma control limits."'he efficiency of the liquid scintillation counters is determined at least annuaHy by counting NIST traceable standards which have been diluted in a known amount of distilled water and various amounts of quenching agent."'he background of each counter is measured with each batch of samples.A control chart is maintained for the background and check source measurements as a stability check.Results are reviewed before being entered into the data system by the Quality Assurance and/or the Department Manager for reasonableness of the parameters (background, efficiency, decay, etc.).Any results that are suspect, being 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 icsults based on experience, a new aliquot is analyzed.The complete information about the sample is contained on the worksheets accompanying the sample results.Teledyne Brown also participates in the US EPA Interlaboratory Comparison Pa)gram to the fullest extent possible.That is, they participate in the program for all radioactive isotopes prepared and at the maximum&cquency of availability. Beginning with 1996, the US EPA discontinued providing milk and air particulate filter samples.Teledyne purchased comparable spiked samples from Analytics, Inc.Tables 6-3 and 6-4 present the Teledyne Brown quality control data icsults for blanks and spikes, respectively. Table 6-5 pments the results of the 1998 EPA Intercomparison as icported to the Supply System.Footnotes in the table refer to investigations of problems encountered in a few cases and the steps taken by Teledyne Brown to prevent esurience. Table 6-6 presents the Analytics Cross Check Comparison results for 1998.No deviations from written procedures occurred during 1998.A summary of the quality control blank and spiked sample results follow.Iodine-131 Cartridges A blank charcoal filter was analyzed with each group of samples assayed.Fifty-two blanks were analyzed in 1998.The average activity was-1.8 J 10.0 E-01 total pCi.Activities were calculated without considering detection limits.Gross-Beta -Filters One blank filter was measured with each set of filters assayed.Fifty-two blanks were counted for 1998.The average activity 1.0 J 0.2 E+00 total pCi, which indicated a relatively stable background for the filter and the gross beta proportional counters.6-3 1998 REMP ANNUAL REPORT I-131-Milk A blank milk was analyzed with each youp of samples assayed.The msults showed that there was no contamination in the laboratory or counting area.The measurements of the blank samples indicated that there was no bias on the low background counters.The average activity for eighteen samples in 1998 was-1.3 J 9.8 E-02 pCi/liter without considering detection limits.In addition ten blanks were analyzed as part of the Teledyne Brown Engineering -Environmental Services'uality control program.The average result for 1998 was 5.3+15 E-01 pCi/liter. Sr-90-Milk and Water Eleven blank water samples were analyzed during 1998.The average result, without considering the detection limits, was 1.2+1.9 E-01 pCi/liter. Eleven spiked water samples were analyzed during 1998, The average value of the samples was 3.4 J 0.4 E+01 pCi/1 compared with a spike level of 3.5 J 0.6 E+01 pCi/1.During 1998, a total of ten spiked milk samples were analyzed.The average value of the samples was 3.2+0.9 E+01 pCi/1 compared with a spike value of 3.5 J 0.6 E+01 pCi/l.These results were within the limits as specified by the EPA Intercomparison Studies Program.Ten blank milk samples were analyzed with an average activity of 6.6 J 2.9 E-01 pCi/1 of Sr-90, which is the natural content of milk.Gross Beta-Water Eleven blanks were prepared from distilled water.The average result without considering detection limits for 1998 was 1.3 J 3.7 E-01 pCi/1.Eleven gross beta samples with a spike level of 2.2+0.7 E+01 pCi/1 were analyzed during 1998.The average zesult was 2.1+0.3 E+01 pCi/1.The msults were well within the guidelines outlined in Table 2,of the document,"Environmental Radioactivity Laboratory Intercomparison Studies Program," EPA-600/4-81-004. Tritium in Water Thirteen blank samples were analyzed during 1998.The average result, without considering detection levels, was 1.0 J 6.9 E+01 pCi/I.Thirty:n tritium samples with a spike level of 1.7 J 0.5 E+03 pCi/1 were analyzed by liquid scintillation counting during 1998.The average result was 1.5+0.2 E+03 pCi/I.Gamma Spectroscopy A blank water sample was analyzed weekly in the garrrma spectroscopy laboratory.

SUMMARY

The Washington Public Power Supply System Radiological Environmental Monitoring Program (REMP)evaluates the radiological impact of Plant 2 operations on the environment in the Airborne, Direct Radiation, Waterborne, and Ingestion pathways as specified in the Offsite Dose Calculation Manual (ODCM).The Supply System's Plant 2 is a 1200 MW commercial nuclear power plant that achieved initial criticality on January 19, 1984.Samples of air, water, milk, soil, sediment, fish and garden produce were collected throughout the year and analyzed for radionuclides specific to plant operations. Radiation levels were also monitored continuously during 1997 with thermoluminescent dosimeters (TLDs).The samples were collected in established areas near the plant and at other locations which could be affected by Plant 2 effluents. This information was compared to samples taken in areas that were unlikely to be affected by plant operations. The 1997 REMP data was also compared to data collected during previous years of plant operation and to the data collected prior to initial plant operation. Most of the results of samples collected by the REMP during 1997 were below detection levels.Some analyses, such as gross beta in air and water, were above the detection level for nearly all samples.This is due to the low detection limit for the gross beta analysis and also to the abundance of naturally occurring beta-emitting radionuclides in the environment. Other results above detection levels, such as cesium-137 in soil and sediment, reflect the effect of past Hanford activities or fallout from Chernobyl and past nuclear weapons testing.Tritium concentration in discharge water continued to be lower than the mean levels observed from the 1992 through 1996 periods.This reduction is due to an ongoing reduction in the volume of the radwaste discharges to the Columbia River.The REMP analytical results and TLD results were demonstrated to be accurate through intercomparison programs which are provided as part of the quality assurance activities conducted during 1997.Such intercomparisons tested the performance of the Supply System monitoring program to other monitoring programs using known radioactive standards. The Supply System REMP analytical contractor performed well in the Environmental Measurements Laboratory (EML)Quality Assessment Program, Environmental Protection Agency Intercomparison Studies, and the Analytics, Inc.Cross Check Comparison Program conducted during 1997.In 1996, the Supply System also participated in the Quality Assurance Task Force (QATF)intercomparison for soil samples.The results for this intercomparison were received in the spring of 1997.The QATF is chaired by the Washington Department of Health and has as its members the various environmental programs on the Hanford Site.The Supply System results for this intercomparison were also favorable. The analytical data collected by the REMP in 1997 remained consistent with the environmental data collected during the preoperational period and prior operational years.Based on the data, no significant new trends or changes in the environmental radiological levels around the plant were observed.l997 REMP ANNUAL REPORT \I

3.0 INTRODUCTION

3.1 Site Description The Washington Public Power Supply System's Nuclear Plant 2 is located in a sparsely populated shrub-steppe region within the Department of Energy's 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, Pasco and Kennewick, which are 12 miles south, 18 miles southeast, and 21 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 1997'ind frequency distribution in Figure 3-1, the focus of REMP sampling is the farming region east of the plant site.Because Plant 2 is located on the Hanford Site, other potential sources of radioactive materials are in close proximity to Plant 2.For this reason, sampling locations near the plant provide useful information for separating the potential effects of Plant 2 from those of the other sources on the Hanford Site.3.2 Program Background The REMP is designed to conform to the regulatory guidance of the Nuclear Regulatory Commission (NRC)as provided by Regulatory Guides 4.1tu and 4.8"', including the Radiological Assessment Branch Technical Position"'. lilac': 1!i NW le%WNW 4,7%~SO>i~"':- ,.;.C ,.C~'8%N I.D%$.7%I.t<x NE l.7%2~7%Q3.;.C M%The quality assurance aspects of the program and tS%'.:C;:;.:.'l% the thermoluminescent dosimetry are conducted Figure 3-1 Average Wind Direction During 1997 in accordance with Regulatory Guides 4.15"'nd 4.13"'.The REMP also must adhere to the requirements of the Washington Energy Facility Site Evaluation Council (EFSEC)'", the Plant 2 Technical Specifications"'nd the Offsite Dose Calculation Manual (ODCM)'".These requirements cover not only the environmental sampling and sample analysis aspects of the program, but also the reporting and quality assurance requirements of the program.The preoperational phase of the program, which lasted from March 1978 until initial criticality in January 1984, provided a baseline of background environmental data.The variability in the background levels of radioactivity is due to differences in geologic composition, Chernobyl and nuclear weapons test fallout, meteorological conditions and seasonal changes.3-1 t 997 REMP ANNUAL REPORT REMP environmental samples are analyzed by a contract analytical laboratory. Teledyne Brown Engineering Environmental Services in Westwood, New Jersey has performed the analysis of REMP samples since June 1986.The thermoluminescent dosimeters used in the REMP to assess the direct radiation were processed in the past by the Supply System.In 1996, the Supply System contracted with ThermoNUtech, to process the TLDs in their West Richland laboratory. In 1997, ThermoNUtech moved their laboratory to Albequerque, New Mexico.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 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 NRC non-routine reporting levels listed in the ODCM.In addition to evaluating the environmental concentrations against federal standards or limits, the REMP also compares the results to state standards."""""" 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.t 3.3 Program Objectives The REMP provides a mechanism for determining whether the levels of radioactivity in the plant environs are within established limits and to ensure 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"" criteria for releases of radioactive effluents are met, the REMP provides supplemental verification that the concentrations of radionuclides in the environment are not greater than anticipated. 1997 REMP ANNUAL REPORT 3-2

4.0 PROGRAM

DESCRIPTION The requirement for the Radiological Environmental Monitoring Program (REMP)is defined by the WNP-2 Offsite Dose Calculation Manual (ODCM).The sampling plan presented in Table 4-1 in this report shows which samples are required by the ODCM and provides a summary of the sample locations, collection frequency, and types of analyses performed. 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 Sample

Locations Eighty-three sample locations were included in the 1997 monitoring program.Seventy-five indicator and three control (i.e.background) stations were located within 10 miles (16 kilometers) of Plant 2.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 primarily on factors such as population distribution and meteorological conditions and 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 listed in Tables 4-1 and 4-2 are shown in Figures 4-1 and 4-2.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)and the Sanitary Waste Treatment Facility (Station 102), which are NPDES sites.Also shown are the containerized storage area (Station 118), the cooling tower landfill (Station 119)and the spray pond drainfield (Station 120)which are special interest stations.4.2 Land Use Census The land use census for areas 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 1997 land use census within 5 miles of Plant 2 are given in Table 4-3.No changes from the 1996 land use census were observed.No milk animals are located within the 5-mile radius.The nearest milk location is located 7.2 miles east-southeast of Plant 2.4-1 1997 REMP ANNUAL REPORT

4.3 Sampling

Methods Environmental samples were collected according to the program plan in Table 4-1.All samples were collected by Supply System personnel. Documented procedures for sample collection and TLD analyses are contained in the Supply System's Environmental and Analytical Laboratory Instruction (EALI)manual.The sample analyses procedures are prepared and maintained by the analytical contractor and reviewed by the Supply System prior to implementation. The following sections describe the sampling and preparation methods..4.3.1 Direct Radiation During 1997, thermoluminescent dosimeters (TLDs)were used to determine the direct radiation levels at sixty (60)monitoring locations listed in Table 4-1.In January 1997, TLD Station 65 was added.This station is 7.3 miles south of Plant 2 and is located near a new housing development. Also, TLD stations ST120-West and ST120-Control were removed.The remaining station, ST120-East, is located midway down the bank of the spray pond drainfield trench near the area of greatest sediment deposition. The VLDs at ST119-Control will serve at the control station for ST120.The control station TLD (background) is located at Station 9A in Sunnyside. The remaining TLDs served as indicator TLDs throughout the year.Two sets of TLDs placed three feet above ground were employed at each location.One set of TLDs were exchanged on a quarterly basis (Quarterly TLDs)and the other exchanged on an annual basis'(Annual TLDs).Exposure received by the field TLDs during transport to the TLD sites was monitored by a set of trip control dosimeters that accompanied the field dosimeters to and from the field locations. Another set of TLDs were used as building controls which were used to determine the exposure of the TLDs at the controlled storage location.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.Since 1995, the REMP has used Harshaw TLDs and since 1996, the environmental dosimeters have been processed by a vendor, ThermoNUtech. The environmental dosimeters were processed on either a Harshaw Model 8800 or a Harshaw Model 6600 TLD Reader.The file generated when the Harshaw TLD reader processes the environmental TLDs was stored in the host computer and used as input for the Harshaw algorithm that calculates environmental doses.The TLD reader was typically calibrated within 7 days prior to processing field TLDs.The TLD reader was calibrated in generic units using calibration cards irradiated on a ThermoNUtech Sr-90 source."Relative response" factors (gU/R)were used by the dose algorithm to convert an element reading in gU from the reader to the Roentgen equivalent reading.The exposure values determined for calibration exposures, as well as the exposures of some QA dosimeters (processing control dosimeters), were based on a National Institute of Standards and Technology (NIST)traceable Sr-90 source.The exposure values for the audit dosimeters (spiked dosimeters) were based on the calculated field strength of a Supply System Cs-137 source.Ionization chamber measurements-made during TLD exposure 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 to resolve the difference. 1997 REMP ANNUAL REPORT 4-2 Two Reuter Stokes pressurized ionization chambers (PICs)provided additional capability 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.4.3.2 Airborne Particulate/Iodine Air particulate and air iodine (1-131)samples were obtained through 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 43)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 filter media are'changed weekly and shipped to the analytical contractor for analysis within, one or two days of collection. New air sampler units were purchased in 1997, and were placed in service beginning in May.By the first week in October, all of the sampler units had been replaced.4.3.3 Water There were nine locations for water sampling in 1997: three for the evaluation of river/drinking water, one for plant discharge water, three for groundwater, one for the storm drain water, and one for sanitary waste water.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 sample location is also used for a drinking water sample since Plant 2 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 ODCM 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.The Station 27 sample is also considered an indicator sample.Composite samplers are installed at the Columbia River pumphouse to monitor the plant intake water (Control Station 26), and the cooling tower discharge line (Station 27).There are composite samplers at the two drinking water locations (Stations 28 and 29).The samplers collect 25-ml aliquots of water at regular intervals of time or flow.Non-routine analyses on the drinking water samples include strontium-90 and iodine-131 analysis.Strontium-90 analysis is required when the gross beta activity exceeds either 8 pCi/liter or ten times the mean of the 4-3 1997 REMP ANNUAL REPORT previous three months'ctivity for a specific location.Iodine-131 analysis is required when the dose calculated for the consumption of water exceeds one millirem per year.Neither of these analyses were required during 1997.There are three wells within the vicinity of Plant 2 that are used as groundwater sampling locations. These are a deep well on the Plant 2 site (0.1 mile north of the Reactor Building)and two wells on the WNP-1 site (1.2 miles downgradient from Plant 2).Water from the Plant 2 well can be used as a backup source for drinking and fire protection'. Water from the WNP-1 wells supplies the drinking and fire protection water for the WNP-1 site.Although none of these wells draw from the unconfined aquifer, they are considered indicator samples.Quarterly grab samples were, taken from each.of these.wells.One.gallon (3.8 liters)was collected from each well for gamma analysis and one liter was drawn for tritium analysis.Water samples were collected from the storm drain outfall (Station 101)using a flow proportional composite sampler.These samples were analyzed for gross beta, gamma and tritium.EFSEC Resolution No.259 for the Sanitary Waste Treatment Facility (SWTF;Station 102)requires a monthly sample to be taken at the headworks (102B)which was analyzed for gamma and tritium and two samples prior to discharge (102C)which were taken at the discharge weir of the south pond.Those samples were analyzed for gross alpha, gross beta, gamma and tritium.In addition, one sample was taken from the west end of each pond and analyzed for gross beta, gamma and tritium.Beginning in April of 1997, the SWTF began reiving sanitary waste from the U.S.Department of Energy's 400 Area.The Supply System installed a flow meter an'd composite sampler on the 400 Area sewer line just above where the 400 Area/Plant Support Facility (PSF)intertie is-located.This sampler takes a flow-proportional composite sample which was collected at least monthly.Gross alpha and beta analyses, tritium analysis, and gamma analysis were performed on each sample.4.3.4 Soil As required by the Site Certification Agreement (EFSEC Resolution No.260"'), annual soil samples were taken at the indicator stations, Stations 1, 7, 21 and 23.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.Each sample was collected from an area of approximately one square foot to a depth of approximately one inch.Approximately two kilograms of soil were collected in each sample.Soil samples were shipped to the analytical contractor after collection and analyzed for gamma activity.If the gamma isotopic analysis indicates that cesium levels in any of the indicator samples exceeds ten (10)times the level in the control sample, a strontium analysis is performed on the sample(s). 'o strontium analysis was required during 1997.1997 REMP ANN VAL REPORT 4-4

4.3.5 Sediment

For the second year, only the fall collection of the semiannual sediment could be taken.High water levels in the Columbia River covered the two sample sites well into the early summer.The fall sample was collected at the end of October.The upstream sediment sample (Station 33)was collected from a location approximately two miles upriver from the plant discharge. The downstream sample (Station 34)was collected approximately'one mile downstream of the plant discharge. Each sample consisted of approximately two kilograms of the shallow surface sediment scooped from below the waterline. The samples were shipped to the analytical contractor. Sediment samples were also taken from the storm drain (Station 101)outfall and pond and the SWTF.(Station 102)north stabilization pond.Sediment sampling in these locations was performed in a manner similar 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. A 2-kilogram sample of dried cooling tower sediment was collected from the sediment disposal ell (Station 119)within thirty days of the completion of cleaning the cooling towers.In 1997 the cooling towers were cleaned once, hence, only one sample was collected for gamma spectrometry analysis.4.3.6 Hsh The annual fish sampling was performed in late September and early October.Fish samples collected from the Columbia River (Station 30 in Figure 4-1)were indicator samples, whereas the fish collected on the Snake River (Stations 38 and 38A in Figure 4-2), were control samples.Three separate fish samples, consisting of an anadromous species and two other species generally considered edible or potentially edible (such as carp, catfish and whitefish) were collected at each location.All the fish were collected using electro-shocking except the samples of the anadromous species which were collected from the Ringold hatchery on the Columbia River and at the Lyons Ferry Fish Hatchery on the Snake River.The fish were filleted to obtain approximately one kilogram of edible flesh per sample.The fillets were placed in clean plastic bags and frozen until shipment to the analytical contractor. Fish are sampled annually unless elevated radiation levels related to plant operations are observed, in which case sampling is conducted semiannually. 4.3.7 Milk Milk samples were collected monthly January through March and October through December and semimonthly during the spring and summer months when the cows were likely to be grazing or on fresh feed.Enough raw milk was collected from each sampling location to obtain a one gallon sample after the cream had been skimmed off.The samples were refrigerated overnight and the cream skimmed off the next morning., The milk samples were chilled.and shipped to the analytical contractor within a day of collection. 4-5 1997 REMP ANNUAL REPORT the tion Routine samples were collected from two indicator locations (Stations 36 and 64)across Columbia River in Franklin County.Milk samples were also collected at one indicator sta (Station 9B)and one control location (Station 96)in the Sunnyside/Grandview area (in Figure 4-3).Station 9B in Sunnyside serves as an'indicator station because a portion of the feed for the cows at that location is hay from Fraiiklin County north of Pasco.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. Apples were collected in September from Station 91, the Rio Vista Farms orchard, which is irrigated with Columbia River water.t 4.3.9 Vegetation The annual sample of vegetation growing in the storm drain pond was collected in June.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.4.4 Analytical Procedures The analytical procedures used for the 1997 REIVIP samples are described below.Teledyne Brown Engineering Environmental Services performed all routine analyses of REMP samples during 1997.4.4.1 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 filters.4.4.2 Measurement of Gamma Emitters A shielded Ge(Li)detector system was coupled to a computer-based data acquisition system which performed pulse height and gamma energy analysis.The information collected about each peak was compared to a library of known peaks.Isotopic identification was performed as was the radioactivity calculation which used the appropriate fractional gamma ray abundance, half-life, detector efficiency, and net counts in the peak region.1997 REMP ANNVAL REPORT 4-6 Milk and Water A 1-liter Marinelli beaker was filled with a representative aliquot of the sample.The sample was then counted for at least 1000 minutes (16.7 hours).Foodstuff As much of the edible portion of the sample as possible was loaded into a tared Marinelli beaker and weighed.The sample was then counted for at least 1000 minutes (16.7 hours).~Ve etat ion As much sample..as.possible is placed in a 1-liter Marinelli beaker and counted for approximately 1000 minutes (16.7 hours).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 Marinelli beaker and weighed.The sample was then counted for at least 360 minutes (6 hours).Charcoal Cartrid es Air Iodine Charcoal filters were counted up to five at a time, with one positioned on the face and up to four on the side of the calibrated Ge(Li)detector.The detection limit for a charcoal cartridge was uniquely determined for each filter and by using its position.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.Air Particulate Filters Four air particulate filters for a quarterly composite from each field station were aligned one in front of another and counted for at least 360 minutes (6 hours).4.4.3 Gross Beta Activity in Water A o'e-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 a stable iodide carrier.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 a 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 4-7 1997 REMP ANNUAL REPORT yield was corrected by measuring the stable iodide content of the water with a specific ion electrode. During 1997, this procedure was used only on intercomparison samples, since the doses calculated via ODCM methodology for the consumption of drinking water did not exceed one millirem per year.4.4.5 Tritium in Water The analysis of tritium in water was performed utilizing 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.4.4.6 Strontium-89 and 90 in Water, Milk and Soil During 1997, strontium analyses were not required for any routine REMP water, milk or soil samples.It was used for 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 is reduced by evaporation. Strontium was precipitated as Sr(NO,), using fuming (90%)nitric acid.Milk Stable strontium carrier was added to one liter of sample.The sample is then evaporated and ashed in a muffle furnace.The ash is dissolved and strontium precipitated as a phosphate. The sample is then redissolved and strontium precipitated as Sr(NO,), using fuming (90%)nitric acid.Soil and Sediment The sample is first dried under heat lamps and a 10-gram aliquot is taken.Stable strontium carrier is added and the sample is leached in hydrochloric acid.After the mixture is filtered, phosphates are then precipitated, collected by filtration, and dissolved.in nitric acid.Strontium is precipitated as Sr(NO,), using fuming (90%)nitric acid.A barium chromate scavenge and an iron (ferric hydroxide) scavenge are then performed. Stable yttrium carrier is added and the sample is allowed to stand for five days or more for yttrium ingrowth.Yttrium is then precipitated as hydroxide, dissolved and reprecipitated as oxalate.The yttrium oxalate is mounted on a nylon planchet and counted in a low-level beta counter to infer strontium-90 activity.Strontium-89 activity is determined by precipitating SrCO, from the sample after yttrium separation. This precipitate is mounted on a nylon planchet and covered with an 80 mg/cm'luminum .absorber for low-level beta counting.4.4.7 Iodine-131 in Milk Two liters of sample are first equilibrated with stable iodide carrier.A batch treatment with anion exchange resin is used to remove iodine from the sample.The iodine is 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 l997 REMP ANN VAL REPORT 4-8 chemical yield and mounted on a nylon planchet for low-level beta counting.The chemical yield is corrected by measuring the stable iodide content of the milk with a specific ion electrode. 4.5 Data Analysis Methods Since mid-1984, the results of the REMP analyses have been presented 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 bias 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."ass than the lower limit of detection (LLD)." A listing of the LLDs determined for each analysis is provided in Table 4-4 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 dist'ributions, 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.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." The standard error, which is the estimate of the precision of the mean, is used for the means of quarterly and annual data and is an indicator of the uncertainty associated with the results.The mean results of the quarterly TLDs are compared with the results of annual TLDs and expressed as a ratio by dividing the quarterly results by the annual result.4-9 1997 REMP ANNUAL REPORT TABLE 4-1 P RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM PLAN SAMPLE TYPE" 1.'IRBORNE SAMPLE STATION+'UMBER SAMPLING AND COLLECTION FREQUENCY"'YPE AND FREQUENCY OF ANALYSIS Particulates and radioiodine 1, 4-8, 9A, 21, 23, 40, 48, and 57 Continuous sampling;weekly collection (6/12)'+Paiticulate: Weekly gross beta'>;gamma isotopic@of quarterly composite (by location)Iodine: Weekly gamma analysis.Soil+'(0/7) 2.DIRECT RADIATION 9A, 1,7, 21 and 23, 101, 11.8 Annually Quarterly or more often as needed.Gamma isotopicto; strontium-90"'amma isotopic TLD@(34/6 1)PIC 3.WATERBORNE 1-8, 9A, 10-25, 4047, 49-51, 53-.56, 71-86 (1S-16S)9, 119B, 119-Control, 120-East Various locations, as needed"'uarterly, annually Continuous recording, as needed Thermoluminescent output;quarterly and annual processing.

TABLE 4-1 (Cont.)Soil samples are collected to satisfy the requirements of the Site Certification Agreement (SCA)"'or 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.TLD refers to thermoluminescent dosimeter. For purposes of the REMP, 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-up dosimeter areas)in each badge case.TLDs used in the REMP meet the requirements of Reg 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 ODCM Table 6.3.1.1-1 (3.12-1).Their alternate designations are 1S-16S.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 1997 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.(m)(n)Composite (integrated grab)samples are collected with equipment which collects an aliquot at time intervals that are short relative to the compositing period.A When the gross beta activity in drinking water exceeds 8 pCi/liter, a strontium-90 analysis is performed.(o)When the dose calculated via ODCM methodology for consumption of water exceeds 1 mrem per year, iodine-131 analyses are performed on the drinking water samples.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 radius of the plant and one in a control location.(s)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. TABLE 4-1 (Cont.)(t)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.(u)There are no commercially important species in the Hanford Reach of the Columbia River.Most recreationally important species in the area are anadromous (primarily salmonids), which ascend rivers from the sea for breeding.Four fish species will normally be collected by the electroshock technique in the vicinity of the plant discharge (Station 30)and from the Snake River (Station 38).If electro-shocking 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.If insufficient anadromous fish samples are produced through electro-shocking on the Columbia River, samples may be obtained at the Ringold Fish Hatchery.(v)If an impact is indicated, sampling will be conducted semiannually.(w)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.(x)Station 91 is an apple orchard irrigated with Columbia River water.The apple crop from Station 91 is sampled annually.
