ABSTRACT This report presents the data obtained through the analyses of environ-mental samples collected through the Portland General Electric Trojan Nuclear Plant Environmental Radiological Surveillance Program for the period January 1, 1984 through December 31, 1984.

The levels of radioactivity and specific radionuclides observed during 1984 were comparable to the preoperational baseline and operational data accumulated since the. Trojan Nuclear Plant achieved criticality in December 1975. Ir. no case did radioactivity which may be attributed to

the Trojan Nuclear Plant exceed the design objectives of the Trojan Radiological Environmental Technical Specifications.

I

1.0 INTRODUCTION

The Trojan Nuclear Plant, a 1130 MWe pressurized water reactor, first achieved criticality on December 15, 1975. This report presents the analytical data from the Environmental Radiological Surveillance Program with appropriate interpretation for 1984.

The analytical contractor during this period has been Eberline Services Division, a division of Thermo Electron Corporation. In comparing data obtained during this period with those from previous periods, care should be taken to ensure that differences in procedures between the several contractors are considered. This is particularly true for " gross beta" measurements for which.the use of different reference nuclides may pro-duce appropriately significant differences in gross beta concentrations.

Information concerning the Environmental Radiological Surveillance Pro-gram prior to this period may be found in earlier reports.

, 2.0 SAMPLING AND PROGRAM PROCEDURES 2.1 SAMPLING LOCATIONS Eighty-two sampling locations are used in the Environmental Radiological surveillance Program,' 76 on land and 6 in the Columbia River, which is one less sampling location than used at the end of 1983. In. April 1984, the air monitor at Sample Location 3 (Lindberg-Kelley residence) was dis-4 continued because there was no need for a sample location between the existing air monitor locations at the site boundary (Location II) and at the City of Rainier (Location 2). The remainder of the sampling loca -

tions for 1984 were the same as those described in the report for 1983 I

-(PGE-1006-83).

The sampling locations are shown in Figures 2-1 and 2-2. Table 2-1 includes a listing of the sites, their distance from Trojan, and the type i and frequency of sample collection.

J 2.2 SAMPLING PROCEDURES 1

2.2.1 AIR PARTICULATE AND RADIOIODINE Air particulate and radioiodine sampling was performed weekly. The samples. wore gathered with a portable, low-volume air sampling device which is designed to draw a constant flow rate regardless of filter load-ing. The sampling devices were set to maintain 1 efs. The sample pump, 4 metering-devices, and timer were in a weatherproof housing. The filter l and cartridge were located in an inlet parallel to and about 1 meter above the ground. Glass fiber filters were used to collect particulate matter. Activated charcoal cartridges were used to collect radiolodine.

The glass fiber filter was removed from the air sampler and placed in a

.2-in. plastic petri dish. The activated charcoal cartridge was removed at the same-time. Air flow readings and other data required to compute the levels of radioactivity were recorded and submitted to the analysis laboratory along with the samples.

2-1

2.2.2 AMBIENT RADIATION MEASUREMENTS USING TLDs 4

Thermoluminiscent dosimeters (TLDs) were placed for field exposure and collected on a quarterly frequency. The dosimeters were placed about 1 meter above ground level in plastic containers. The time of collec- '

tion, the exposure period, and any abnormal conditions such as moisture in the holders, damage done by animals, etc. were recorded when the dosimeters.were retrieved. Care was taken to minimize exposure to the TLDs between collection and delivery to the laboratory. The TLDs were f

transpoeted to the field in lead boxes to ensure low background levels.

Control TLDs were carried with the field TLDs during collection and delivery.

During the period of July-August 1984, the TLD field exposure quarter periods were redefined from January-April, April-July, July-October, and October-January to February-May, May-August, August-November and November-February. This change was made so that the TLD field exposure periods would more closely match those of the Oregon State Health Division.

2.2.3 PRECIPITATION Rainwater samples were collected monthly from precipitation reservoirs.

The reservoir was removed from its holder and agitated to ensure thorough mixing of the contents. The contents were measured with a graduated

~

cylinder and the volume recorded on the sample label. One gallon, or.the total volume if it was less than 1 gal, was placed in a polyethylene collection bottle. Sixty mi samples were taken for tritium analysis.

. Concentrated hcl was added to the large water sample only. The identifi-cation number of the sample site, the date collected, and the volume 1 measured were recorded on the data collection forms.

1 2.2.4 TERRESTRIAL SOIL Terrestrial soil samples of about 1 quart in volume were taken twice a year. The soil samples were taken from a 1 sq ft area with the vegeta-

. tion and large rocks removad before sample collection. The soil i 2-2 1

sampling depth varied between 1 to 4 in. and the soil was passed through a No. 6 sieve before placement in the plastic collection bottles. The collected terrestrial soil samples along with information such as the sample site identification number, the date collected, and the volume obtained were recorded on the collection forms.

2.2.5 TERRESTRIAL VEGETATION Grass samples were collected semiannually. Representative samples of tuberous and foliar fruits and vegetables were collected during local harvesting. Grass samples were obtained from a sizable area because of the large (2-3 lb) sample size. Grass was removed at ground level.

Samples were sealed in plastic bags immediately following collection, taking care not to include any soil or foreign material. The sample site identification number, the date collected, the sample type, and the volume obtained were recorded on the data collection forms.

2.2.6 TERRESTRIAL ANIMALS Animal samples were taken semiannually from cattle and goats purchased from local farmers after determining that the animal had been raised on the local farm. Samples taken from each animal included muscle, heart, and liver. Muscle specimens were approximately 3 lb each, but the entire heart and liver were collected. The sample site identification number, the date collected, the sample type, and volume obtained were recorded on the collection data forms. Samples were packed in plastic containers and refrigerated until shipment.

2.2.7 MILK Milk samples (cow or goat) were collected monthly. Milk was collected in polyethylene bottles (2 gal for cow dairy and 1 gal for goat dairy).

Prior to shipment of samples to the analysis laboratory, an ion exchange resin was used to concentrate any iodine present to improve detection sensitivity. The whole milk (after iodine removal) and resins were labeled and collection data forms prepared specifying sample site, date collected, sample type, and volume obtained.

2.2.8 WELL WATER 7

E Well water was collected quarterly either from the tap that leads off the g pump or directly from the well itself. At sites with faucets the line -g -

was purged for 1 min prior to collection. Sixty m1 were drawn from the 'N 1-sal sample for tritium analysis. The remainder of the sample was put in a 1-gal pe ' ethylene bottle and acidified with concentrated hcl. The M bottles were securely sealed, labeled, and collection data forms prepared 3 specifying site, collection date, volume, and sample type. ]  %

Large rocks removed before sample collection. The soil sampling depth varied between 1 to 4 in. and the soil was passed through a No. 6 sieve before placement in the plastic collection bottles. The sample site identification number, date collected, and volume obtained were recorded on the collection data forms.

2.2.12 AOUATIC VEGETATION Aquatic vegetation samples were taken semiannually. Rooted species were obtained in shallow, quiescent areas of the surface water during the growing season when they were emergent. Filamentous (slime) species and mosses were obtained from submerged rocks. Samples were collected with trowel or clippers where appropriate. Three to 5 lb of equ. tic grass was collected. Samples were sealed in bags with care taken not to include soil or foreign material. The sample site idencification number, date collected, sample type, and volume obtained were recorded on collection data forms.

2.2.13 AOUATIC ANIMAL t

Aquatic animal (fish) sampling was performed semiannually. Both indigenous and anadromous species were acquired by seining, netting, or trapping.

If the fish fork length exceeded 8 in., the fish were filleted. At least 2 lb of fish muscle was obtained from each location with a mixing of panfish species if needed. The sample site identification number, the date collected, the fish species, and the volume obtained were recorded on collection data forms.

-3.0 ' ANALYTICAL DOCEDURES AND COUNTING METHODS

[ . Samples are analyzed for the various radioactive components by standard radiochemical methods. These methods are equal to, and in most cases, identical with, those of the USDOE (HASL Procedures Manual, MASL-300, Health and Safety Laboratory, U. S. Atomic Energy Commission, 376 Hudson Street, New York, NY 10014) or-those of the U. S. Environmental Protec-tion Agency (EPA).

Analyses of individual sample types, general methods, and routine ana-lytical sensitivities are discussed below. The analytical program and.

4- sensitivity requirements are given in Table 3-1.

3.1 ANALYTICAL DETECTION LIMITS AND COUNT RATE m aRS t

! In environmental radiological analyses the dominant known uncertainty is usually the sample count rate. Error terms given in this report are 7

based on this factor since all other analytical uncertainties are rela-i tively small. Uncertainties are calculated by standard methods (see Reference 4), and are reported at the 95-percent confidence level (20). The lower limit of detection (LLD) is defined as "that concen-tration which is 3 times the standard deviation error of the average concentration in a blank or background sample". Analytical data for samples for which concentrations are less than or equal to the LLD are preceded by the symbol "<".

3.2 AIR PARTICULATES 4

Gross beta concentrations are measured with low background gas flow

! (proportional and/or Geiger) counting systems with anti-coincidence back-ground suppression. The routine detection limit (LLD) is 0.002 pC1/m 3

.for gross beta or gross alpha based on 300'a / week.

Gamma isotopic analyses are performed with germanium detectors with a

, routine detection limit of about 0.05 pCi/m for most gamma emitters 3

for single filters and about 0.01 pCi/m for monthly composite samples.

3-1

l

)

3.3 RADI0 IODINE

-The charcoal cartrid6es used are of the TEDA-impregnated type. The iodine is extracted from the charcoal, chemically separated, and counted as AgI using wide beta or low beta counters which yield an LLD of 3

0.1 pCi/m . l l

l j 3.4 RAINFALL. SURFACE WATER. AND WELL WATER Gross beta analysis of water samples is performed by evaporation of a measured aliquot of the sample, digestion, planchetting of the processed sample and radiometric assay by low-level beta counting, with an LLD of 0.5 pCi/1. Tritium analysis is performed on all water samples to the required LLD of 1000 pCi/1 by liquid scintillation counting. Gamma isotopic analysis is performed using germanium detectors with a routine LLD of 25 pC1/1 per gamma emitting radionuclide.

3.5 SOIL OR SEDIMENT l

, Samples are oven-dried and results reported based on dry weight. Gamma

emitters are measured with germanium detectors with an LLD as specified.

The analysis for Sr-89 and Sr-90 is performed on ashed samples using a strontium chemical yield and two-separation technique.

4 i 3.6 VEGETATION. MEAT. POULTRY. FISH. AND FOOD CR0pS Measured amounts of these types of samples are analyzed for gamma emitters by gamma spectrometry with counting times adjusted to provide LLDs at least as sensitive as those required in Table 3-1 for the appropriate sample type. The analysis for Se-89 and Sr-90 is performed on ashed samples using a strontium chemical yield and two-separation technique.

3.7 MILK 1

The determination of I-131 in fresh allk is based on anion exchange ,

removal'of the I-131 followed by radiochemical purification and low 3-2

i background beta counting. The LLD is 0.2 pCi/1 or better and the overall accuracy at 0.5 pCi/1 is 25 percent or better at the 95-percent confi-dence level. Gamma emitters i.n milk are measured with germanium detec-tors. The analysis for Sr-89 and Sr-90 is performed on ashed samples using a strontium chemical yield and two-separation technique.

3.8 AMBIENT RADIATION MEASUREMENTS The responsibility for ambient radiation dose measurements resides with Portland General Electric Company (PGE). A total of 66 field locations were monitored with the dosimeters analyzed quarterly. The field

~

dosimeters used thermoluminescent radiation detection materials (CaF2 Dy er TLD-200 chips) with each dosimeter having more than two separate f

chips or measurement devices. For each field dosimeter, the chips were packed in a plastic foam and sealed in plastic containers. To minimize radiation energy dependence for the TLD-200 chips, the field dosimeters were shielded with a two-element filter of 10 mil tantalum and 2 mil lead as described in the report by Denham, et al.

1 Calibration of the field dosimeters was performed with Cs-137 sources traceable to the U. S. National Bureau of Standards. Calibration dosimeters were prepared for each readout of the field dosimeters.

3.9 CUALITY CONTROL l

Approximately 15 percent of the analyses performed by Eberline are for quality control purposes. Eberline participates in Environmental Protec-tion Agency, International Atomic Energy Agency, Nuclear Regulatory Commission, several states', and other intercalibration programs.

-Reports of all quality control analyses are presented monthly to PGE.

Results of EPA intercalibrations (for which "known" data are available) are given in Table 3-2. In those cases where discrepant values are obtained, an investigation is undertaken to determine the cause, and corrective action as required. Table 3-3 summarizes the intralaboratory

. quality control results for the year 1984.

During 1981, 1982, and 1984, PGE participated in the Fifth, Sixth, and l Seventh International Intercomparison of Environmental Dosimeters. The results of the Fifth and Sixth Intercomparisons were presented in the 1982 and 1983 reports. The Seventh Intercomparison results are shown below and the PGE values are comparable with the project values.  !

4.0 RESULTS AND DISCUSSION

-4.1 SAMPLES FROM THE TERRESTRIAL ENVIRONMENT l 4.1.1 AIR PARTICULATES AND AIRBORNE I-131 l-l

! The gross beta air particulate data obtained during 1984 was comparable to the data obtained during the years of 1982, 1983, and the preopera-

tional period. Gross beta concentrat. ions for air particulates remained generally at low levels throughout the year. Average concentrations for the years 1984 and before are presented in Table 4-1 for both onsite and 5

offsite locations. In October 1980, the Peoples' Republic of China tested a nuclear device in the atmosphere. For this reason, the increased average concentrations in 1981 were due to increased fallout levels from the October 1980 Chinese test and not from operation of the

, Trojan Nuclear Plant. In all cases, the gross beta concentration values in 1984 were below the design objective level of 0.1 pCi/m .

.For 1984, the gross alpha concentration values for the monthly composites of air particulate filters were either at the detection limit (0.002 pC1/m ) or slightly above (0.003 to 0.010 pC1/m ). In only one caso did the gross alpha concentration values for 1984 reach the

design objective level of 0.01 pCi/m (Location IF in January). The quarterly average value was 0.006 0.004 pCi/m for Location IF during the first quarter of 1984.

I i

l Airborne I-131 concentration values for 1984 were below the detection limit of 0.1 pCi/m3 (at collection time) in all cases.

Data for these air monitoring samples are listed in Chapter 5. The air particulate gross beta concentration data are plotted vs time throughout

1984 for each air monitoring station and are listed in Chapter 5.

l 4.1.2 TgtRg8 TRIAL ANIMALS samples of various organs from beef cattle and goats were collected and analyzed for radiostrontium and gassa emitters. Strontium-90 activity 4-1 f

was detected in two samples, but it was due to worldwide fallout and not the operation of the Trojan Nuclear Plant. Strontium-89 and gasuna emitting radionuclides were not detected in animal tissue samples. The data are presented in Chapter 5.

t 4.1.3 POOD CEOPS I

Samples of food crops were collected and analyzed for radiostrontium and I

sensas emitters. Strontium-90 activity was detected in one sample, but'it j - was due to worldwide fallout and not the operation of the Trojan Nuclear Plant. Strontium-89 and gamma emitting radionuclides were not detected f in the food crop samples. The data are presented in Chapter 5.

2 4.1.4 TERRESTRIAL VEGsTATION Samples of grass were taken aL six locations and analyzed for radio-

+

strontium and gansna emitters. Camma emitting radionuclides and Sr-89 were not detected in these grass samples, though one of the samples had measurable concentrations of Sr-90. The activity detected in this grass sample originated from worldwide fallout and was not attributable to operation of the Trojan Nuclear plant. Data are presented in Chapter 5.

4.1.5 wet.L WATER .

r 1

i Well water samples were collected quarterly from five locations. t.ow  ;

levels of gross beta radioactivity were detected which are to be expected i

from natural sources. Tritium levels were below the sensitivity require-monts of the program, which shows that the gross beta radioactivity detected in these samples is not due to Trojan Nuclear Plant operations. 'i Data are presented in Chapter 5.

I 4.1.6 MIt.K I i

Milk samples were collected from seven locations, and were analyzed for l I-131, and radiostrontium and gansas emitters. Most samples contained j Se-90, which is attributable to worldwide fallout. No samples contained  ;

f Y

4-2

r I-131, Sr-89, or gamma emitters at detectable levels, which confirms that

[_ the Sr-90 is attributable to worldwide fallout. Data are presented in Chapter 5.

l 4.1.7 301L l'

! Soil samples were collected from seven locations and analysed for samma isotopic and radiostrontium concentrations. Data indicate the presence of no radioactivity attributable to the operation of the Trojan Nuclear Plant. Traces of Cs-137 and Sr-90 were found in most samples. The presence of these two nuclides is attributed to worldwide fallout from atmospheric nuclear tests (see Section 4.1.1). Data are presented in l Chapter 5.

3 4.1.8 PRECIPITATION Month 1/ samples of precipitation were collected from three locations and analyzed for gross beta and tritium content. Radionuclides (other than

} natural) were not detected in the samples. Although numerical differences in gross beta concentrations were observed in the samples, there were no I

significant differences between stations based on the tritium data which are much more useful for comparison than are the beta data. Data are presented in Chapter 5.

4.1.9 AMBIENT RADIATION LEVELS

! Ambient dose rates in mR/ day for the dosimeters for measurement locations i

that have been established since before the Trojan Nuclear Plant began 1

operations are shown in Chapter 5. The mean and standard deviation for 1

i the quarterly dosimeters data from these 22 locations was calculated to be 0.12t0.02 mR/ day, which does not differ from the ambient dose rate of

( about 0.13 mR/ day measured in previous years. The mean and standard l- deviations were also calculated for the three geographical groups in 1984 the mean daily dose rates were 0.12t0.03 mR/ day for the eight Trojan onsite locations; 0.13t0.02 mR/ day for the seven Oregon locations; and 0.12t0.02 mR/ day for the seven Washington locations, which also 4-3

l 4

agrees with the similar data from 1983 and before. Furthermore, the 1 ambient gasuna radiation data in Table 5-12 were analyzed for dose rate differences in the four major compass directions from the Trojan Nuclear Plant and no significant differences were found.

4 Tables 5-13 through 5-16 present plots of the environmental dosimeter

)

data for 1984. Separate plots are presented for those dosimeters within the Trojan Nuclear Plant exclusion area boundary and for increasing radial distance groupings from the Plant.

4.2 SAMPLES FROM THE ADUATIC ENVIR0" =r i

1 4.2.1 SURFACE WATER AND DRIMEING WATER SAMPLES i

i surface water samples were collected monthly and quarterly from locations near the Trojan site and included samples from the Columbia River, ponds, and municipal water supplies. Analyses were made for gross beta activity, q tritium, and gansna emitters. The data are presented in Chapter 5.

j No activity which is attributable to operation of the Trojan Nuclear Plant was detected in any of the water samples.

4.2.2 SEDINENT AND SHORELINE SOIL sediment and shoreline soll were collected from lakes and streams in the j

Trojan area as well as from the Columbia River. Analyses were performed for gasuna emitters. The data are presented in Chapter 5. None of the l sediment or shoreline soll sarmies showed detectable levels of gasuna emitters. '

4.2.3 AQUATIC PLANTS

i Aquatic plants were sampled semiannually from the Columbia River and ponds in the vicinity of the Trojan Nuclear plant and analyzed for radio-

,. strontium and gansna emitter concentrations. The data are presented in Chapter 5. Several of the aquatic plant samples showed detectable I,

4-4 I

concentrations of Sr-90 and Cs-137. Since none of the aquatic plant samples showed detectable levels of Sr-89, the measured Sr-90 levels were due to worldwide fallout and not Trojan operations. Likewise, since Cs-134 was not detected, the Cs-137 was probably due to worldwide fall-out. In addition, the measured concentrations of Cs-137 were less than the design obj etive values for edible leafy vegetables such as lettuce.

4.2.4 FISH Fish and crawfish were collected twice during the year and the fillets and/or tails were analyzed for radiostrontium and gama emitters. No radioactivity attributable to the Trojan Nuclear Plant was detected in any of the samples analyzed. The only non-naturally occurring radionuclides detected were Se-90 and Cs-137, which is due to long-term worldwide fall-out (see Section 4.1.1). This conclusion is supported by the fact that the radionuclides Sr-89 and Cs-134 were not detected in crawfish samples, S

which would have been the case if the detected radionuclides were from operation of the Trojan Nuclear Plant. In both cases, the measured con-centrations of Sr-90 and Cs-137 were less than the design objective values for fish. Data are presented in Chapter 5.

5.0 COMMENTS ON AND TERMS USED IN DATA TABLES L Wet Weight A reporting unit used with organic tissue samples such as vegetation and animal samples in which the amount of sample is taken to be the weight as received from the field with no moisture removed.

Dry Weight A reporting unit used for soll and sediment in which the amount of sample is taken to be the weight of the sample after removal of moisture by drying in an oven at about 110'C for about 15 hr.

PCi/m A reporting unit used with air particulate t.nd radio-iodine data which refers to the radioactivity content 4

expressed in picocuries of the volume of air expressed in cubic meters passed through the filter and/or the charcoal trap. Note that the volumes are not corrected to standard conditions.

Camma Ramitters Samples sore analyzed by high resolution germanium gamma or spectrometry. The resulting spectrum is analyzed by a Camma Isotopic computer program which scans about 50 to 2000 kev and lists the energy peaks of any nuclides present in con-centrations exceeding the sensitivity limits set for that particulat experiment.

Error Terms Figures following "i" are error terms based on counting uncertainties at the 20 (95-percent confidence) level. Values preceded by the "<" symbol were below the stated concentration at the 30 (99-percent confidence) level.

Sensitivity In general, all analyses meet the sensitivity require-monts of the prosram as given in Table 3-1. For the few samples that do not (because of inadequate sample quantities, analytical interference, etc), the sensitivity actually obtained in the analysis is given.

5-1

Comment When all analyses of a particular type during the period resulted in concentrations below the sensitivity limits, a statement is made on the appropriate table rather than presenting a whole page of "<" data. If all but one or two data points are below the sensitivity limits, the previously mentioned convention is followed and the finite data are given as footnotes.
