INTRODUCTION This document reports on the operational radiological environmental monitoring program conducted during 1983 for the Surry Power Station.

The analytical portion of this program was conducted by NUS Corporation (NUS) under contract to the Virginia Electric Power Company.

This annual report of the radiological environmental monitoring program s*ummari zes

the results of measurements and analyses of data obtained from samples collected during the reporting period.

A.

Site and Station Description The Surry Power Station of Virginia Electric Power Company consists of two Westinghouse pressurized water reactors, each with a generating capacity of 788 MHe.

Unit 1 has been in operation since July 1, 1972*,

Unit 2 since March 7,1973.

The station is located on a peninsula in the James River, approximately 25 miles upstream of Chesapeake Bay.

Cooling water is taken in downstream of the site and discharged 5.7 miles upstream of the intake.

B.

Objectives and Overview of the Surry Power Station Monitoring Program United States Nuclear Regulatory Commission (NRC) regulations (10 CFR 50.34) require thai nuclear power plants be de~igned, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA).

To ensure that these criteria are met, the operating license for Surry Power Station includes Technical* Specifications ~hich govern the release of radi cacti ve effluents

In-plant monitoring is used to ensure that these predetermined release limits are not exceeded.

However, as a precaution against unexpected and undefined processes which might allow undue accumulation of radioactivity in any sector of the human environment, a program for monitoring the plant environs is also included.

Various environmenta.l samples are collected at indicator and *control or background 1 oca tions and analyzed to determine if changes *in radioactivity levels may be attributable to the operation of the station.

Measured values are compared with background l~vels.

The background levels at ~ny one location are not const~nt, but vary with.

time due to external events such as cosmic ray bombardment, weapons test fallout, an~ seasonal variations.

These levels also vary spatially within relatively short distances as a reflection of geological composition.

Data collected prior to plant operation are used to indicate the degree of natural variation to be expected.

These preoperational data are compared with data collected during the operational phase to assist in evaluating the radiological impact of plant operation.

The objectives of an operational radiological environmental monitoring program are:

o To fulfill the obligations of the Surry Power Station Technical Specifications; o To determine whether any* statistically significant increase occurs in the concentration of radionuclides in any critical pa th; o To detect any buildup of long-lived radionuclides in the en vi ronmen t; o To verify that radioactive releases are within allowable limits and that plant operations have no detrimental effects on the health and safety of the public or on the environment; o And, to establish measurement and assessment methods capable of rapid mobilization during unplanned releases and emergencies.

In 1983 the radiological monitoring program included the mea~urement of ambient gamma radiation by thermoluminescent dosimetry; the determination of gross alpha, gross beta, and gamma emitters in air particulates; the measurement of airborne I-131 in charcoal cartridges; the determination of gamma emitters in river bottom sediment,

fish, crabs, clams, and oysters; the measurement of gamma emitters, tritium, and strontium-89 and -90 in river water; the determination of gross a 1 pha and beta. and tritium in we 11

water, surface water; the determination of gross beta and tritium in precipitation; the determination of gamma emitters, iodine-131, calcium and strontium-89 and -90 in milk; the measurement of gamma emitters and strontium-89 and

-90 in food crops; and the determination of gamma emitters in soil and waterfowl.

SAMPLING PROGRAM Table 1 summarizes the sampling program for Surry Power Station during 1983.

The symbols on this table refer to the sample locations shown on Figures 1 to 3.

Figure 1 shows the locations of land based sampling in the environs of the station, while Figure 2 shows the locations of river based sampling stations.

The small triangles in Figure 3 indicate the positions of environmental thermoluminescent dosimeters (TLDs) at the site boundary.

Samples are collected by VEPCO personnel except for those 1 i sted as state splits, which are collected by the Commonwealth_of Virginia. All samples are shipped to the NUS Radiological Laboratory in Pittsburgh, Pennsylvania.

A.

Program Exceptions No air*samples were collected from station FE for the week of 09/06/83-09/14/83 due to pump failure.

No air particulate filter was collected from station SS for the week of 07/26/83-08/02/83.

T~e I-131 analysis on the milk sample from station LEE HALL for the

. month of December was lost due to a broken container.

The milk sample from station WMS for the month of June was lost during ashing in preparation for gamma spectrometry, due to a furnace malfunction.

The stronti.um-89, -90 analysis on this sample was also lost, as well as the strontium-89, -90 analysis on the sample from this station for the month of May.

The milk sample from station JDKs for the month of September was depleted in other analyses and no gamma spectrometry could be

-performed.

Values for five quarterly TLD measurements are not reported. Three were missing at the time of pickup. These were the second quarter TLDs for location 04 and the fourth quarter TLDs for locations 07 and 08.

Two additional fourth quarter TLD locations, 14 and 15, were not recorded as missin~ at the time of pickup, but were not received for analysis by the laboratory.

Air iodine was collected by drawing air through TEDA impregnated charcoal cartridges.

Air particulates were collected by drawing air though a 47-millimeter diameter glass-fiber filter.

In the laboratory, air par~iculate filters were analyzed for gross alpha and gross beta activity, and were composited quarterly for analysis by gamma spectrometry.

Charcoal cartridges were analyzed for iodine-131.

Milk was collected from one control and four indicator locations on a

monthly basis.

Samples from the LEE HALL and EPPS locations were collected by and split with the Commonwealth of Virginia.

All milk samples were analyzed for iodine-131, gamma emitters, stable calcium, and strontium-89 and -90.

Precipitation samples were collected as monthly and quarterly composites from one control and one indicator location.

Gross beta and tritium analyses were performed on both types of composites.

water samples in.eluded well water, surface water and river water.

Well water was sampled from four locations on a semi-annual basis..

Gross alpha, gross beta, and tritium analyses were performed on these samples.

Surface water was sampled from four locations on a semi-annual basis.

Gross alpha, gross beta, and tritium analyses were performed on these samples.

Two types of river water samples were collected.

Monthly composites were taken from one control location upstream of the plant and an indicator station at the plant discharge location.

These composite samples were collected by and split with the Commonwealth of Virginia; they were analyzed for gamma emitters and strontium-89 and -90.

Bi-monthly river water samples were also collected from one control and four indicator locations.

These were analyzed by gamma spectrometry on a bi-monthly basis and composited for semi-annual analysis of tritium.

The James River is an estuary near Surry Power exchange of water with Chesapeake Bay occurs.

Oysters were also collected bi-monthly from three indicator locations for analysis by gamma spectrometry.

River bottom silt (sediment) was collected semi-annually from one control and four indicator locations for analysis by gamma spectrometry.

One waterfowl sample was analyzed by gamma spectrometry.

Seven samples of food crops were collected during 1983 for analysis of gamma emitters and strontium-89 and -90.

These included cabbage, kale, corn, peanuts, and soybeans from four indicator locations.

Annual samples of soil were taken from six indicator locations near air samplers and analyzed by gamma spectrometry.

Thermoluminescent dosimeters (TLDs) were used to determine the direct (ambient) radiation levels at monitoring points.

For routine TLD measurements, a dosimeter of CaS04:oy*in a Teflon card wai deployed at each selected location. Dosimeters were exchanged on a quarterly basis.

Additional sets of dosimeters were shipped with each exchange cycle to serve as in-transit controls.

For routine exchanges, TLDs were shipped by Federal Express.

Individual dosimeters were calibrated by exposure to an accurately known radiation field from a calibrated Cs-137 source.

SUMMARY

AND DISCUSSION OF 1983 ANALYTICAL RESULTS Data from the radiological analyses of environmental media collected during the report period are tabulated a~d discussed below.

The procedures and specifications followed in the laboratory for these analyses are as required in Section 5.0 of the NUS Environmental Services Division Quality Assurance Manual, and are detailed in the NUS Radiological Laboratory Work Instructions.

Radiological analyses of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods.

(1) The use of 11LT 11 in the data tab-les is the equivalent of the less than symbol (<) and is consistent with the NUS Radiological Laboratory practice of data reporting.

The number following the 11 LT 11 is a result of the lower limit of detection (LLD) calculation as defined in Appendix B.

11 ND 11 (Not Detected) is used periodically in the tables presenting gamma analysis results for various media.

It primarily appears under the "Others" column, where it indicates that no other detectable gamma emitting nuclides were identified.

NUS analytical methods meet the LLD requirements addressed,

in Table 2 of the USNRC. Branch Technical Position of Radiological Monitoring (November 1979, Revision 1).

(2)

Tables 3 through 25 give the radioanalytical results for individual samples. A statistical summary of the results appears in Table 26.

The reported averages are based only on concentrations above the limit of detection.

In Table 26, the fraction (f) of the total number of analyses which were detectable follows in parentheses.

Also given in parentheses are the minimum and maximum values of detectable activity during the report period.

A.

Air Iodine/Air Particulates Results of airborne iodine-131 analyses on charcoal* cartridges are presented in Table 3.

I-131 was not detected in any of the samples.

Results of gross alpha and gross beta analyses on air particulate filters are given in Tables 4 and 5. 3 The mean gross alpha activity for all stations was 3.8 + 2.6 E-03 pCi/~ and the range of gross alpha activity was 1.2 to 20 E-03 pCi/m 3 T~e mean gross beta activity for a 11 stations was 16 + 19 E-03 p~i /m and the* range of gross beta activity was 3.2 to 78 E-03 pCi/m.

Air filters were composited quarterly and then analyzed by gamma spectrometry.

The gamma spectrometry data is presented in Table 6.

Cosmogenic beryllium-7 was detected in 2~ of 32 samples.

The range of Be-7 activity *was 32 to 110 E-03 pCi/m.

Three samples for v1hich LLDs were measured also fell within this range.

Cesium-134 and cesium-137 were found in the first and second quarterly composites from Surry Station (SS).

Both isotopes may be the result of plant effluents.* This station is located within the plant boundary and is not an environmental location.

Cesium-137 was also detected at one environmental location in th~

third quarter.

Mi 1 k The results of iodine-131 analyses of milk samples are presented in Table 7.

No I-131 was detected in any of the samples.

A total of 59 analyses were performed, 47 from indicator locations and 12 from the Williams (WMS) control location. The required sensitivity limit of 1 pCi/1 for I-131 in milk could not be met for the December milk sample from station EPPS due to delay between sample collection and arrival at the 1 abora tory.

Milk samples were also analyzed by gamma spectrometry and the results are shown in _Table 8.

A total of.58 samples were analyzed, 47 from indicator locations and 11 from the WMS control location. The required sensitivity limits of 60 pCi/1 for Ba-140 and 15 pCi/1 for La-140 were not met in 10 of the analyses, due to delay in analysis.

The La-140 sensitivity limit was also exceeded in two additional analyses due to delay between sample collection and arrival at the laboratory.

As expected, naturally occurring*K-40 was the major detectable activity in the milk samples.

Detectable levels of cesium-137 were found in 15 of 58 samples, ranging from 1.4 to 43 pCi/1.

Since Cs-137 is present in global

fallout, the occasional detection of this isotope in environmental media is not unusual.

With two exceptions,* the results fell well within the expected range of activities due to long term fallout.

On~ value, 43 pCi/1, was higher than expected, although occasional results in this range have been reported for other programs.

In a second sample, Cs-137 was accompanied by Cs-134 at a level of 10 pCi/1.

The presence of Cs-134 is indicative of the release of radioactivity from the plant.

This possibility has been previously noted in the discussion of air particulate analytical results.

NRC non-routine reporting levels for these isotopes are 60 pCi/1 for Cs-134 and 70 pCi/1 for Cs-137, and the levels found are well below these action levels.

Stable. (non-radioactive) calcium in milk was also determined in 60 samples at an average level of 1400

+ 340.

These analyses were performed by the NUS Laboratory Services Division rather than by the NUS Radiological Laboratory.

Strontium-89 and strontium-90 were determined in 58

samples, 48 from indicator locat~ons.and 10 from the WMS control location. Results for these analyses are listed in Table 10.

Stro~tium-89 was not detected in any of the samples analyzed.

Strontium-90 was found in 5 of 58

samples, ranging from 1.6 to 3.5 pCi/1.

Two of the four samples were from indicator locations; the remaining two were from the WMS control location.

Strontium-90 is likely to be due to global fallout.

During the preoperational radiological monitoring program for Surry Power Station, stronti~m-90 was detected in milk samples at a range of 5.2 to 13 pCi/1.

Precipitation Precipitation samples were collected as monthly composites and analyzed for gross beta and tritium. Quarterly samples from the same locations (one indicator and one control) were composited from monthly aliquots retained at the site.

This compositing was performed by station personnel and the composites were submitted for the san~ analyses as monthly samples.

The results of these analyses are shown in Table 11.

In some cases, the. gross beta results on the quarterly samples appear to be at variance with the results from monthly samples.

In all these cases the reported value was confirmed by reanalysis.

Sampling, storage and compostting methods were reviewed with VEPCO and the reason for the discrepancies remain unresolved.

Tritium was detected in 6 of 32 analyses. The values were typical for environmental samples.

D

Water Well water was collected from four indicator locations during May and October.

The results of gross alpha, gross beta, and tritium analyses on these 8 samples are sho\\'m on Table 12.

No alpha activity was found in any of the samples (stations SS, HIR, BC, and JMTN).

Gross beta activities ranged from 1.8 to 11 pCi/1, well within the preoperational range of O to 25 pCi/1. Tritium was.detected in 2 of 8 analyses at typical environmental levels.

Table 12 also includes gross alpha, gross beta, and tritium results on 8 surface water samples which were also collected during May and October.

Surface water stations are Chippokes Creek '(CC) and three reservoirs (WMR,

NNR, and SR).

All are indicator locations.

Gross alpha activities of 4 and 9.6 pCi/1 were found in 2 of the 8 samples.

The range of gross beta activity was 1.4 to 23 pCi/1.

The maximum value in this range was confirmed by reanalysis; this sample contained high suspended solids.

No tritium was detected in any of these samples.

In addition to the water samples discussed above, samples of James River water are collected as both. monthly composites and bi-monthly grab samples.

The James River is an estuary near Surry Power Station and undergoes tidal exchange with Chesapeake Bay.

River water samples thus represent saline bay water in contrast to the fresh water samples discussed above.

Ga~ma spectrometr~ was performed on bi-monthly grab samples of James River water and the results are presented on Table 13.

With four exceptions, all nuclides were below the detectiorr limit. The May sample from Surry Discharge (SD) contained 5.5 pCi/1 Co-58, 9.8 pCi/1 Cs-134, and 11 pCi/1 Cs-i37.

These nuclides may be due to plant operations.

In

addition, the November sample from Hog Island Point (HIP) contained 3.7 pCi/1 Cs-137.

When unaccompanied by Cs-134, Cs-137 is likely to be due to atmospheric fallout.

The bi~month1y samples of river water were composited on a semi-annual basis and analyzed for tritium.

Low positive values of 200 and 290 pCi/1 were found in samples from the Chicahominy River (CKIC) control location.

Values for.the indicator lotations ranged from 220 to 1500 pCi/1.

These results are given on Table 14.

During the preoperational radiological environmental monitoring program, higher values of 4500 to 15000 pCi/1 were reported.

Monthly composites of river water are col"lected by the Commonwealth of Virginia.

Results of gamma spectrometry on these samples are shown in Table 15.

With four exceptions, all nuclides were below the detection limit.

The February sample from the indicator location~ Surry Discharge, contained 12 pCi/1 of Co-58 and 27 pCi/1 of Co-60.

Co-60 was again detected in th~ November sample from the same location, at a level

of 3.8 pCi/1, and was accompanied by 2.6 pCi/1 of Cs-137.

These nuclides may be due to plant operations.

The monthly composites of river water are also analyzed for strontium-89 and -90.

Results are shown on Table 16.

(Ten of these analyses were incomplete at the time of submission of the draft annual report.

Low levels of Sr-90 (0.68 to 0.98 pCi/1) were found in samples from both the indicator and control (Scotland Wharf) locations.

During the preoperational. radiological environmental mbnitoring program for Surry Power Station, Sr-90 was occasionally found in James River water in the range 0.1 to 3.1 pCi/1.

In addition, strontium-89 was detected in the two samples collected in April.

The levels observed were 1.0 + 0.6 and 1.6 + 1.1 pCi/1. These va 1 ues for stronti um-89 may be art'ifacts of the calculation method.

Because this analysis is a function of the difference between two counts, normal statistical variations will occasionally lead to the reporting of a false positive result for this isotope at values near its detection limit.

The analysis could not be confirmed because sufficient volume of sample no longer remained to match the original sensitivity 1 imH.

E.

Aquatic Biota Marine biota can be sensitive indicators of radionuclide accumulation in the environment because of their ability to concentrate certain chemical elements wh.ich have radioactive isotopes.

Gamma spectrometry was performed on bi-monthly samples of clams and oysters from the James River.

The results are shown on Table 17.

As

expected, naturally occurring K-40 was the nuclide most frequently detected.

In one sample from station LC, Co-60 was found at a low level of 18 pCi/kg (wet weight). All other nuclides were below the detection limit.

I I i Crabs were also collected during July, August, and September from the Surry Discharge (SD) location and analyzed by gamma spectrometry.

Naturally occurring K-40 was found in all three samples, as shown on Table 18.

The August sample contained 13 pCi/kg Cs-134 and 18 pCi/kg Cs-137 on a wet weight basis. These nuclides could be due to plant operations.

Eel and catfish were collected during February and August from the same SD location.

The results of gamma spectrometry on these samples are shown on Table 19.

K-40 was found in all four samples.

The eel sample from February contained 100 pCi/kg Co-58 and 50 pCi/kg Co-~0.

The catfish sample from February contained 6.7 pCi/kg Cs-134 and 12 pCi/kg Cs-137.

(All results are given on a wet weight basis.) Only the eel sample from August showed positive activity for any nuclide other than K-40; it contained 37 pCi/kg Cs-137.

These nuclides could be due to plant operations, although the Cs-137 may also be attributable to global fallout.

F.

Sediment Sediment samples were collected twice during this program year.

All samples were analyzed by gamma spectrometry:

five locations were submitted in March and six 1 oca ti ons in September.

A number of man-made and naturally occurring radioisotopes were detected in these samples.

The isotope cesium-137 was detected in all samples, ranging from 56 to 2900 pCi/kg (dry).

Cesium-134 was detected in 8 of 10 indicator samples ranging from 180 to 1300 pCi/kg (dry). Cobalt-60 was detected in 7 of 10 indicator samples.

Its range was from 310 to 2400 pCi/kg (dry).

Cobalt-58 was detected in one indicator sample at 1900 pCi/kg (dry).

The only man-made isotope in the single control sample collected was Cs-137.

In addition to the man-made isotopes discussed above, a number of naturally occurring isotopes were observed in all samples.

Potassium-40 was detected in all samples, ranging from 3000 to 17000 pCi/kg (dry)~

An assortment of daughters from the uranium and thorium chains were also detected in all of the samples.

These generally ranged from 97 to 1100 pCi/kg (dry) between the different samples.

The observed results were internally consistent for any.given sample.

G.

Waterfowl A single waterfowl sample was collected for 198j from Hag Island Reserve (HIR).. This sample was analyzed by gamma spectrometry, the results or which are shown in Table 21.

The man-made isotope cesium-137 was detected at a value of 4.7 pci/kg (wet).

The naturally occurring isotopes K-40 and Be-7 were also detected at 420 and 42 pci/kg (wet),

respectively.

The values for the K-40 was not unexpected nor unusual.

The Be-7 value is attributable to the probable ingestion of leafy vegetation or sediment which may contain this particular isotope due *to-its production in the upper atmosphere and subsequent deposition_ on vegetation and soi 1.

Food Products A total of seven food products were collected for analysis during this program year.

Two samples each of corn and peanuts were submitted for analysis as,,.,ell as individual samples of cabbage, kale.and soybeans.

All samples were analyzed by gamma spectrometry as well as for strontium-89 and -90.

No man-made.radioisotopes were detected in any of the sample$.

The naturally occurring isotope potassium-40 was observed in all the samples.

The observed values (2300 to 5600 pCi/Kg (wet)) were within the expected range of normal distribution.

I.

Soil Soil samples were collected from six locations during this program year.

All samples were analyzed by gamma spectrometry *. The only man-made radioisotope detected was cesium-137.

This isotope was detected in all but one

sample, ranging from 270 to 830 pCi/Kg(dry).

In addition, a number of naturally occurring isotopes were observed in all samples

Potassium-40 was detected in all samples, ranging from 2100 to 15000 pCi/Kg(dry).

An assortment of daughters from the uranium and thorium chains were also detected in all of the samples.

These generally ranged from 100 to 1700 pCi/Kg(dry) between the different samples.*

The observed results were internally consistent for any given sample.

Finally, one sample contained detectable activity of beryllium-? at a level of 520 pCi/Kg(dry). This is a naturally occurring radioisotope which is produced in the upper atmosphere. It is often detected in air particulate samples, and quite commonly seen on leafy vegetation and in soil samples.

Direct Radiation Environmental radiation dose rates determined by thermoluminescent dosimeters (TLDs) are given in Table 25.

TLD badges of four readout areas each were deployed quarterly at each location.

The mean values of four readings (corrected individually for response to a known dose and for in-transit exposure) are reported in this table, unless indicated otherwise.

A description of the TLD system used is contained in Appendix C.

A statistical summary of the 1983 data is included in Table 26.

Individual measurements of external radiation levels in the environs of the Surry site ranged from 0.11 to 0.82 mR/day.

Annual: levels ranged from 47 to 130 mR/year.

The values obtained for location 00 (an onsite lead pig controll and location 01 (an onsite station near a waste holding area) are not included in the statistical summaries.

Exposures at the onsite location 01 were elevated throughout the year.

TLD results from the first and second quarter indicated an anomalous exposure to a low energy radiation source.

Each TLD placed in the field has four separate readout areas, each of which has a different degree of shielding.

This permits a *rudimentary assessment of the energy of exposure *within certain limits.

On initial review, the data exhibited wider variations among the four readout areas-of individual badges than was usual.

Closer inspection revealed a trend wherein the least shielded areas showed the highest exposures, although this was by no means universal.

Using a method supplied by the TLD and badge manufacturer, the readings were corrected for the overresponse to low energy radiation.

Not all the values could be corrected in this way.

There were many instances of inversions (higher response from the more heavily shielded area), tight initial variations, and outliers. Each of these conditions can result in sets of readings which diverge on application of the correction curves.

Fpr Table 25, the corrected readings were reported if the application *of the correction curves to any individual station resulted in a new data set which uniformly converged with respect to the internal variation of the four readings.

Sets for which no low energy corrections were applied are indicated in the data table.

Despite the corrections which were applied, the data for the first and second quarters still shows a high variability.

The results seem to indicate an non-uniform exposure to a source of low energy radiation. This anomalous pattern of results has been observed previously in other programs and has been attributed to accidental shipping or storage in proximity to a source or intentional x-raying enroute for shipping inspection.

In any case, plant releases are not implicated because of the absence of any rational

pattern, in particular, the high exposure exhibited by the control locations.

CONCLUSIONS Results of the 1983 R~diological Environmental Monitoring. Program for the Surry Nuclear Station have been presented.

Generally the fesults were as expected for normal environmental samples.

Naturally occurring activity was observed in the expected sample media in the activity ranges.

One onsite station contained activity of probable plant origin in air particulate samples*and also showed a higher than normal exposure rate.

This station is not a true indicator of environmental contamin*ation.

Occasional samples of nearly all media showed the presence of man-made isotopes. These have been discussed individually in the text. Observed activities were at very lqw concentrations and of no significant dose consequence.

Anomalous TLD readings were observed but there was no basis for concluding that these resulted from any station operations.

Based on the evidence of the environmental monitoring pro~ram the station appears to be operating within regulatory limits.
