]
Nuclear Plant Environmental Radiological Surveillance Program for the period January 1, 1992 through December 31, 1992.
~
Most of the radionuclide analyses on the environmental samples resulted l
in non-detectable values for radionuclides that could be released from i
the Trojan Nuclear Plant.
In no case did radioactivity that could be
~,
attributed to the Trojan Nuclear Plant exceed the Reporting Levels of the Trojan Radiological Technical Specifications.

1.0 INTRODUCTION
J The Trojan Nuclear Plant, a 1130 megawatt-electric pressurized water reactor, first achieved criticality on December 15, 1975. This report I
presents the analytical data from the Environmental Radiological f
Surveillance Program with appropriate interpretation f or 1992.
The analytical contractor during this period has been TMA/Eberline, j
c l
Albuquerque, New Mexico.
In comparing data obtLined during this period
{
with those from previous periods, care should be taken to ensure that
?
differences in procedures among the contractors are considered.
l 1
Information concerning the Environmental Radiological Surveillance Program prior to this period may be found in earlier reports.

2.0 SAMPLING AND PROGRAM PROCEDURES l
~!
l 2.1 SAMPLING LOCATIONS l
Sixty-nine (69) sampling locations were used in the Environmental j
Radiological Surveillance Program in 1992, 68 on land, and 1 in the t
Columbia River. During 1992, no sampling locations were added or deleted r
from the program.
i f
The sampling locations are shown in Figures 2-1 and 2-2.
Table 2-1 l-includes a listing of the sites, their distance from Trojan, and the type and frequency of sample collection.
I f
I' 2.2 SAMPLING PROCEDURES l
2.2.1 AIR PARTICULATE AND RADIOIODINE Air particulate and radiciodine sampling was performed weekly. The samples were gathered with a low-volume air sampling device which is designed to draw a constant flow rate regardless of the pressure drop across the filter.
The sampling devices were set to maintain 1 cim.
The sample pump, metering devices, and timer were in a weatherproof housing.
l The filter 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 j
i radioiodine.
The glass fiber filter was removed from the air sampler and placed in a j
i 2-inch plastic petri dish.
The activated charcoal cartridge was removed j
i at the same time. Air flow readings and other data required to compute
.j the levels of radioactivity were recorded and submitted to the analysis laboratory along with the samples.

2.2.2 AMBIENT RADIATION MEASUREMENTS USING TLDs Thermoluminescent dosimeters (TLDs) were placed f or field exposure and collected on a quarterly frequency. The TLDs were placed about 1 meter l
l above ground level in plastic containers. The time of collection, the i
exposure period, and any abnormal conditions such as moisture in the 6
holders, damage done by animals, etc., were recorded when the TLDs were retrieved. Care was taken to minimize exposure to the TLDs between j
collection and delivery to the laboratory. The TLDs were transported to i
i the field in shielded boxes to ensure low background levels. Control j
TLDs were carried with the field TLDs during collection and delivery.
I 1m2.3 FOOD CROES l
t l
I i-Representative samples of tuberous and foliar vegetables plus fruits were j
collected during local harvesting. Samples of leafy vegetables were j
collected during the months of June, July, and August. Samples were sealed in plastic bags 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 amount obtained were recorded on
[
the data collection forms.
j i
2.2.4 MILK Milk samples (cow or goat) were collected monthly during January, February, and December with collections every two weeks during the other months. Milk was collected in polyethylene bottles (2 gallons for cow dairy and I gallon 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. Collection data forms were prepared specifying sample site, date collected, sample type, and volume obtained.

l 212 5 WELL WAIER Well water was collected quarterly either from the tap that leads off the l
pump or directly from the well itself. At sites with faucets, the line l
was purged for about five minutes prior to collection. Sixty r..illigrams.
f were drawn from the 1-gallon sample for tritium analysis. The remainder of the sample was put in a 1-gallon polyethylene bottle and acidified j
with concentrated EC1. The bottles were securely sealed, labeled, and l
1 collection data forms prepared specifying site, date collected, volume, i
and sample type.
.l i
2.2.6 DRIEEING WAIEE F
Four-week composite samples of municipal drinking water were collected j
for Rainier (Sample Location 2) and St. Helens (Sample Location 66) at their respective intake structures on the Columbia River. Rainier is
.l downstream of the Trojan Nuclear Plant while St. Helens is upstream. At j
each location, a compositing sampler took a sample every 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and l
aliquots of this four-week composite were sent for analysis. From these
]
aliquots, 60 milliliters are sent for tritium analysis and two 1-gallon 9
I polyethylene bottles are acidified with concentrated hcl and sent for the i
other analyses. The bottles were securely sealed, labeled, and i
collection data forms prepared specifying site, date collected, volume, and sample type.
j l
l 2.2.7 SHORELINE SOIL i
i i
Shoreline soil samples of about 1 quart in volume were taken twice a j
year.
The samples were taken from a 1 square foot area with the l
r vegetation and large rocks removed before sample collection. The soil sampling depth varied between 1 and 4 inches 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.

i 212.8 AOUATIC ANIMAL Aquatic animal sampling was performed semiannually. Both indigenous and
.f anadromous species of fish and invertebrates such as crayfish were acquired by seining, netting, or trapping. The radioactivity analysis f
was performed on fish muscle or crayfish muscle samples.
If needed for a particular sampling location, the fish muscle sample may be a mixture of several panfish species. The sample site identification number, the date collected, the fish species, and the amount obtained were recorded on collection data forms.

2.3 YEARLLMHDJSE_ CENSUS WITHIN 5-MILE _MDIUS OF TRDJAN l
The annual land use census within a 5-mile radius of Trojan Nuclear Plant I
was performed during August 1992. Identified by this census were the locations of the nearest residence as well as locations within the 5-mile l
t radius for milk animals-(cow and goat), meat animals, and vegetable j
gardens in each of the 16 meteorological sectors. This census was i
completed by driving the roads within a 5-mile radius of Trojan.
.i 4
4 Table 2-2 presents the' nearest locations for these activities in the j
16 sectors. Table 2-3 presents the locations for the dairy goats l
(there were no dairy cows) within the 5-mile radius. Table 2-4 presents j
the locations for the vegetable gardens within the 5-mile radius.
?
i An evaluation of the previous sampling locations has shown that the i
previous locations are appropriate, and no changes were made in the 9.
sampling locations as a result of the 1992 land use census.

J 3.0 ANALYTICAL PROCEDURES AND COUNTING METHODS l
i Samples are analyzed for the various radioactive components by standard i
radiochemical methods. These methods are equal to, and in most cases, identical with, those of the U. S. Department of Energy [ Health and Safety Laboratory (HASL) Procedures Manual, HASL-300, see references, Section 3.10), or those of the U. S. Environmental Protection Agency (EPA).
i Analyses of individual sample types, general methods, and routine ana-l lytical sensitivities are discussed below. The analytical program and
{
sensitivity requirements are given in Table 3-1.
7 3.1 ANALYTICAL DETECTION LIMITS AND COUNT RATE ERRORS I
b i
In environmental radiological analyses the dominant known uncertainty l
is usually the sample count rate.
Error terms given in this report are
.l based on this factor since other analytical uncertainties are relatively small. Uncertainties are calculated by standard methods (HASL-300), and j
are reported at the 95 percent confidence level (20). The lower limit i
t of detection (LLD) is defined as the smallest concentration of radicactive material in a sample or the smallest amount of radiation to a dosimeter that will yield a net indication, above system background, that f
will be detected with 95 percent probability with only 5 percent probability of falsely concluding that a blank observation represents a real signal. Analytical data for samples for which concentrations are f
less than or equal to the LLD are preceded by the symbol "<".
I l
L2 AIR PAPJ1CIIMIES l
Gross beta concentrations are measured with low background, window-type (0.85 mg/cm in thickness), proportional counting systems. The routine F
detection limit (LLD) is 0.002 pCi/m for gross beta measurements
{

l Gamma isotopic analyses are performed with germanium detectors with a 3
i routine detection limit of 0.05 pCi/m for the gamma emitters.
i l
3.3 RADI0 IODINE l
r I
The charcoal cartridges used are of the TEDA-impregnated type.
The Iodine-131 determination is made with gamma spectrometry counting of i
3 I
seven weekly cartridges together to an LLD of 0.05 pCi/m.
If activity l
is detected, then each is processed separately. The iodine is extracted f
from the charcoal, chemically separated, and counted as AgI using the low-background beta counters mentioned in Section 3.2.
1 6
1.4 DRIRKING AND_WELL_WAIER l
i 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 the low-background beta counters men-I tioned in Section 3.2, with an LLD of I pCi/1. Tritium analysis is j
performed on water samples to the required LLD of 1000 pCi/1 by liquid
)
scintillation counting.
Gamma isotopic analysis is performed using gemanium detectors with a routine LLD of 10 pCi/1 per gamma emitting radionuclide.
l 1,5 SIl0 EEL.IEE SOII, Samples are oven-dried and results reported based on dry weight.. Gamma i
emitters are measured with germanium detectors with an LLD of 0.1 pCi/g per nuclide.
\\
3.6 FISH..__UNERIH RAIES E._ FOOD CRDES 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.

17 MILK i
The determination of Iodine-131 in fresh milk is based on anion exchange i
removal of the Iodine-131 followed by radiochemical purification and low background beta counting using the systems described in Section 3.2.
1 The LLD is 1 pC1/1 or better. Gamma emitters in milk are measured with germanium detectors with an LLD of 10 pCi/1 per nuclide. The analysis for Strontium-89 and Strontium-90 is performed on ashed samples using a strontium chemical yield and two-separation technique with LLDs of
[
15 pCi/1 and 6 pCi/1, respectively.
l.fL_AMBIDiLEADIAT10!LMEASUREMENTS The responsibility for ambient radiation dose measurements resides with i
f Portland General Electric Company (PCE). A total of 57 field locations
'I t
were monitored with the dosimeters analyzed quarterly. The field dosimeters used thermoluminescent radiation detection materials (CaF :Dy, J
2
.TLD-200 chips) with each dosimeter having more than two separate chips or l
measurement devices. For each field dosimeter, the chips were packed in a plastic foam an( sealed in shielded containers. To minimize radiation l
l energy dependence for the TLD-200 chips, the fic1d dosimeters were j
shielded with a two-element filter of 10 mil tantalum and 2 mil lead as
{
described in the report by Denham, et al (see Section 3.10).
I Calibration of the field dosimeters was performed with a Cesium-137 f
source traceable to the U. S. National Institute of Standards and-Technology. Calibration dosimeters were prepared for each readout of the field dosimeters.
3 J___QUALIILCONIROL l
A large number of the analyses performed by the analysis laboratory are i
1 Lfor quality control purposes. The analysis laboratory participates in
.f f
EPA, Nuclear Regulatory Commission, and other intercalibration programs.
Reports of 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 l
obtained, the analysis laboratory performs an investigation to determine f
the cause and corrective action as required. Table 3-3 summarizes the intralaboratory spiked sample results for the year 1992.

During 1981, 1982, and 1984, PGE participated in the Fifth, Sixth, and Seventh International Intercomparison of Environmental Dosimeters. The
]
results of these participations were presented in the 1982, 1983, and f
1984 reports, respectively. By the successful PGE participation in these three intercomparison projects, the measurement method for the environ-mental ambient radiation levels has been shown to be appropriate and accurate.

l 4.0 RESULTS AND DISCUSSION 4.1 SAMPLES FROM THE TERREETRIAL ENVIR0h M iI l
4.1.1 AIR PARTICULATES AND AIRBORNE I-131 The gross beta air particulate data obtained during 1992 were comparable to the data obtained during the years of 1982, 1983, 1984, 1985, 1986 (except May 1986), 1987, 1988, 1989, 1990, 1991, and the preoperational period. Gross beta concentrations for air particulates for sampling periods in 1992 remaineo generally at low levels.
Average concentrations with their average standard deviations for the years 1992 and before are presented in Table 4-1 for both onsite and L
offsite locations.
In October 1980, the People's Republic of China l
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. The larger average standard deviation for the 1986 data was due to the increased gross beta activity for May 1986 resulting from the Chernobyl reactor accident near Kiev, Ukraine.
Airborne I-131 concentration values for 1992 were below the detection limit of 0.05 pCi/m (at collection time).
For 1992, the measurement of gamma emitting radionuclides in quarterly composites of air particulate filters identified Be-7, a naturally-occurring radionuclide, at three sites.
Data for these air monitoring samples are listed in Chapter 5 Tables 5-1, 5-2, and 5-3.

during the harvest months of June, July, and August, 1992. Gamma emitting radionuclides were not detected in the food crop samples. The j
data are presented in Chapter 5, Table 5-4.
l The vendor laboratory did not achieve the required LLD for analysis of l
i 1-131 in vegetation samples during 1992. There were several contributing i
factors to this situation.
i I
i There were long delays between receipt and analysis of the samples. The vendor did not review the analysis data quickly enough to allow a second i
i count due to the short half-life of I-131.
Shorter count times than j
stipulated in the contract were used.
Inadequate review of sample
[
analyses by PGE contributed to the repetition of the problem.
I Corrective actions to be taken by the vendor laboratory have been discussed between PGE and laboratory personnel. These include more j
j timely sample preparation and counting after sample receipt, and j
j adherence to the contract-required sample count times and LLDs.
PGE has j
q shortened the turn-around times in the contract for reporting sample results which, together with more timely sample counting, will allow for reanalysis when necessary. A Quality Assurance audit of the laboratory will be conducted in 1993 to verify the effectiveness of the vendor's l
1 corrective actions.
PGE procedures now require verification that the vendor has analyzed samples at or below the required LLD.

Milk samples were collect ed f rom five locations and were analyzed for j

Some samples contained Sr-90, j
which is attributable to worldwide fallout due to atmospheric weapons f
i tests.
I In an attempt by the vendor laboratory to improve reliability of I-131 analyses of milk samples, a modified procedure was used. The modification was unsuccessful, resulting in unusable data and yielding i
results which did not achieve the required LLD from January through April 1992, i
i Reasons for this problem included lack of timely review by the vendor i
laboratory of sample analysis results, and inadequate overview by PGE of the vendor laboratory performance. The corrective actions taken for this t

Ambient dose rates in mR/ day for dosimeters at measurement locations in i
the environs around the Trojan Nuclear Plant are shown in Chapter 5, j
Table 5-7.
Several of these measurement locations were established I
before the Plant became operational. The mean and standard deviation l
for the quarterly dosimeters data has been calculated for the three geographical groups of Oregon, Washington, and Trojan onsite locations.
For 1992, the mean ambient dose rates were: 0.1010.03 tR/ day for the l
14 Trojan onsite locations, 0.13 0.03 mR/ day for the 20 Oregon locations, f
and 0.1210.02 mR/ day for the 23 Washington locations. Table 4-2 presents

i Another manner for review of the ambient radiation measurements is to l
divide the results between three rings which are grouped as to radial l
distance from Trojan:
the close ring (21 locations) at distances from i
0.1 to 1.6 miles; the 5-mile ring (16 locations) at distances from 3.2 to 6.6 miles; the 10-mile ring (16 locations) at distances'from 7.8 to 10.7 l
miles. The 10-mile ring serves as the control locations for the ambient radiation measurements. Each ring has at least one measurement location in each of the 16 directional sectors. The measurement mean and standard
)
I deviations were calculated to be 0.12 0.03 mR/ day for all locations, with the close, 5-mile, and 10-mile rings being 0.10 0.03 mR/ day, l
0.12 0.02 mR/ day, and 0.13 0.02 mR/ day, respectively. These data j
indicate that the operational activities of the Trojan Nuclear Plant do j
not affect the ambient radiation levels around the Plant.
The ambient gamma radiation data in Table 5-7 were also analyzed for dose l
t rate differences in the four major compass directions from the Trojan l
I Nuclear Plant. No significant differences were found, in respect to both 1

values were: 0.12 0.02 mR/ day for the 16 north locations, t
0.12 0.02 mR/ day for the 9 east locations, 0.14 0.03 mR/ day for the

Table 4-3 presents the annual average of the gross beta activity for the two water sample sites from 1980 through 1992. These samples were not collected prior to 1980. The annual average values do not differ significantly over the years.
4.2.2 SHORELINE _EQ1L Shoreline soil samples were collected from a location on the bank of the Columbia River near the Trojan site. Analyses were performed for gamma emitters. The data are presented in Chapter 5, Table 5-9.
None of the shoreline soil samples showed detectable levels of gamma emitters.
4.2.3 EISH Fish and crayfish were collected twice during the year and the fillets and/or tails were analyced for gamma emitters. None of the fish or crayfish samples contained gamma emitting radionuclides larger than the detection level of 0.10 pCi/g. The data are presented in Chapter 3, Table 5-10.
L3 SLTtM/dLY_Df_.EISULIS Table 4-4 presents a summary of the radioactivity analysis results for each medium or pathway sampled for the 1992 Radiological Environmental Monitoring Program around the Trojan Nuclear Plant. The format of Table 4-4 is that which is required by Trojan Technical Specification 6.9.1.5.2.
A review of Table 4-4 shows that none of the radioactivity measurements, averaged over a quarter year period, were larger than the Reporting Levels defined by Technical Specification 3.12.1.
For the gross beta analyses of the air particulate samples, the control location was the location with the highest annual mean.
Itc mean was not significantly different from the mean value for all locations.

i For the milk samples, the only detectable radioactivity was due to the i
t atmospheric weapons testing and the Chernobyl nuclear accident f allout j
radionuclide, Sr-90.
Also, the dairy with the highest measured values of 1
Sr-90 was a goat dairy (Location 63). Goats tend to concentrate radioactivity in the milk to a greater degree than do cows. These 1992 milk values are consistent with previous evaluations (performed on 1989 i
milk samples) which showed that the measured radioactivities in milk were due to world-wide fallout and not the operations of the Trojan Nuclear-f Plant.
i For the ambient radiation measurements, the mean value for the control locations (10-mile ring) was not significantly different than the mean j
values for all locations or the close ring (see Section 4.1.5).
j i
For the radioactivity measurements in drinking water, the annual.mean for the gross beta determination was higher (though not significantly) f or l
the upstream or control location (St. Helens) than it was for the o
downstream location (Rainier).

As is shown by Table 4-4, there is no indication that the operations of the Trojan Nuclear Plant had a radiological impact on the environs around 1
the Plant.
