ABSTRACT This report presents the data obtained from the analyses of

. ' environmental samples collected through the Virginia Electric Power

• .,\.

Company Surry Station Environmental Radiological Surveillance Program for the period 01 January 1982 through 31 December 1982 The activity present above detection limits in the routinely collected sample media was observed to be of natural and atmospheric fallout origin. The results show that the radiation dose to a member of the general population did not exceed the* technical specifications of 1% of the 10 CFR 20 limit during 1982.

INTRODUCTION The Surry Power Station of Virginia Electric and Power Company consists of two Westinghouse pressurized water reactors each with a generating capacity of 788 MWE. The station is located on a peninsula in the James River approxi-mately 25 miles upstream-of the Chesapeake Bay. Cooling water is taken in down-stream of the site and discharged 5.7 miles upstream of the intake. The Surry Power Station has been designed to minimize radioactive releases and insure that radiation doses attributed to the operation of the station will be "as low as reasonably achievable".

Various environmental samples are collected at indicator and control_or background locations and analyzed to determine if changes in radioactivity levels may be attributable to the operation of the station. This environmental radio-logical monitoring program provides surveillance to assure compliance with the NRC Regulations and the Surry Power Station Technical Specifications.

The program outlined in Tables 1 and 2 has in some cases more frequent collection and analysis of certain samples than called for in the Technical Specifications. The accompanying map shows the plant environs. Table 4 SUI!ID!ar-izes the results of the radiological environmental surveillance measurements during calendar year 1982.

SUMMARY

1982 Environmental monitoring results showed that the radiation dose to a member of the general population did not exceed Technical Specifications of 1% of the 10 CFR 20 limit during 198g.

Radionuclides released to the air and water from Surry Station may con-tribute to the radiation background through both external and internal ex-posure.

The-most significant environmental dose pathways are direct dose from the gaseous effluent and thyroid dose due to ingestion of milk. The area contains only a very small milk shed which limits general population dose potential from this source and since James River water is not used for drinking, dose potential from this source is also 'minimal.

Table 4 summarizes the range and average concentrations- for. measurements at the indicator and control locations~ and the location with the highest annual mean. Complete information is given in the Sample Data Tables.

(Appendix I)

Specific findings for various environmental media are discussed in Section 4.

SECTION 2 SAMPLING PROGRAM 5

• l All samples are collected by VEPCO Environmental Services Personnel and shipped to the Eberline Laboratory in West. Chicago, Illinois. During the first half of the year and to the Eberline Albuquerque Laboratory in New Mexico during the second half of the year.

Upon receipt of the samples, the laboratory staff enters the samples in a log book identifying them as to sample type, collection date, and sample code number or location, then verifies the specific analyses to be performed on each sample. The samples are then stored, awaiting analysis., on shelves expressly for this. purpose to assure accountability through the laboratory processes.

Table l lists the sampling locations and frequencies. Figure 1 shows the locations~ of the various sampling environs.

Table 2 lists the sample analysis program - sample class, frequency, and the type of analysis required.

Table 3 lists the LLD's (Lower Limits of Detection) for the analytical program. These LLD's are based on Regulatory Guide 4.8. For analyses not required in Regulatory Guide 4.8, Federal EPA, former re-quirements for similar programs, or other appropriate guides are used.

The LLD's are calculated as per RG 4.8 at the 3a level.

The Guide specifically states that the LI.D's are a priori NOT a posteriori (after the *fact) limit for a particular measurement. When, however, RG 4.8 or other LLD's have not been achieved, a footnote giving a brief explanation has been inserted.

ANALYTICAL PROCEDURES Samples received at the laboratory are analyzed for the various radio-active components by standard radiochemical methods. These methods are equal to, and in most cases, identical with, those of the U.S.D.O.E.(l) or those of (2) the Federal E.P.A.

• --*: Brief descriptions of analytical procedures are available in the Labor-atory Procedures Manual available at Surry Station and the radioanalytical contractor.' s . laboratory.

Air Particulate Filters Gross Beta - Exposed air particulate filters are counted in low back-ground Geiger or propor.tional flow beta counters using anti-coincidence background suppression after the short-lived naturally-occuring radon and thoron daughters have decayed. Filters are counted long enough to ensure that the required sensitivity (LLD) will be met Gamma Isotopic - Quarterly composites of air particulate filters are counted in high resolution (GeLi) gamma spectrometers for periods of time long enough to ensure that the required pro.gram sensitivity (LLD) is met. (See also introduction to data tables, Section 5.)

Water Samples (Includes Surface, Well, Precipitation, James River)

Gross Beta - A measured aliquot of sample is digested, "wet-ashed",

evaporated, transferred to a tared 47mm stainless steel planchet, dried, and weighed. The planchetted sample is counted long enough in a low background beta counter to ensure that the LLD of the program will be met.

Gamma Isotopic - a measured aliquot of the sample is evaporated to a small controlled volume and counted in a standard geometry in a high resolution (Geli) gamma spectrometer long enoungh to ensure meeting the sensitivity requirements of the program. See also the Introduction to Data Tab],.es.*

Strontium-89 and Strontium carrier strontium is added to a measured aliquot of sample. The strontium is then separated.and purified by either ion: exchange chromatography. (EPA method) or straight wet. chemistry (HASL

method). The chemical yield for.strontium is determined by atomic adsorp-tion* spectrometry or gravimetric methods. After a suitable period (usually 14 days) to allow for ingrowth of Y-90 the: sample is counted -in a low background beta counter* (equilibrim or total Sr* count). The strontium is next* put into solution,. carrie! yttrium added, and the strontium and yttrium fractions. separated *. The, yttrium* is counted and from the y,;.90 (Sr-90 daughter) count, thesr:..90 concentration can be.determined. The difference between the total strontium concentration as determined by the equilibrium .count and the Sr-90 concentration as determined from the Y-90 count is the Sr-89 concentration. Equations are available to permit calculation of Sr-89 and Sr-90 by counting the purified Sr fraction at two points during ingrowth of the Sr-90 daughter Y-90. While either method is acceptable, we find the former method to provide more consistent results:

Tritium - tritium as tritiated water is analyzed by liquid scintillation counting after distillation. If high sensitivity is not required (ie. LLD

-"'500 pCi/1)

• the sample is -disti];led, -mixed-with the appropriate counting phosphors and counted with no further treatment. If higher sensitivity is required (ie. ('u300 pCi/1) the sample is isotopically enriched in tritium concentration prior to liquid scintillation counting.

16

Isotopic enrichment is done by the classical method of Ostlund which involves alkaline electrolysis of a purified aliquot of sample under controlled conditions of temperature and electrode current density.

Milk Samples I-131 - measured amounts of carrier iodide are added to *a known volume of milk and the iodine extracted on anion exchange resin. The iodine is recovered and ourified by classical iodine chemistry methods which

.* i

• are similar to those given in former Regulatory Guide 4.3. The yield or recovery of iodine is measured gravimetrically and the precipitated sample is mounted and counted in a low level beta detector for a long enough period to ensure that. the required LLD is met.

Gamma Isotopic - a measured aliquot of sample is evaporated and oven dried to a standard volume and counted in a fixed geometry in a high resolution (GeLi) gamma spectrometer for a long enough period to ensure that the required LLD's are reached (see also Introduction to data Tables).

Sr-89 and Sr Stable strontium carrier is added to an aliquot of the

• • __

~

sample which is then dried and ashed at high temperature (>700°c). The

• • ,1 ash is dissolved and the solution treated from this point on in the same manne~_as are water samples (Q.v.).

Organic Samples (including Clams, Oysters, Fish, Crabs, Food Crops and Fowl).

Gamma Isotopic Analysis - a measured aliquot of sample is oven dried or ashed as appropriate, placed in a controlled geometry and counted in a high resolution (GeLi) gamma spectrometer for a period long enough to ensure that the LLD's of the program will be met (see also intro. to Data Tables).

17

In the case of samples such as fish and fowl, the edible flesh is sepa-rated from bones and entrails prior to drying.

Sr-89 and Sr stable strontium carrier is added to a weighed aliquot of the sample and the sample is ashed at high temperature (>700°c). The

• -.1 ashed sample is then dissolved and processed in the same manner as are

• *J ' water or milk samples.

Soil and Silt Samples Ga.mma*Isotopic Analysis the sample is oven dried to facilitate handling and then sieved to remove pieces of stone and/or other* large pieces of material. An appropriate sized,. weighed aliquot of the sample is then transferred into a* standard geometry container and counted for a period long enough to ensure that the LLD of the program will be met. (See also Introduction to Data Tables).

Thermoluminescent Dosimeters (TLD)

Environmental radiation doses are measured using badges comprizing fiye.

chips sealed in plastic protective holders having a density of 50 mg/cm 2

• The TLD chips are l/8 1! x 1/8" x 1/32 LiF (thallium activated) known commercially

• .} as Harshaw-100. The chips are all selected to provide uniform response to with-in 5% of the mean for the batch.

Prior to installation, the chips are annealed by a standard cycle of 60 minutes at 400°c and immediate cooling to ambient temperature by placing the tray containing the annealed chips on an aluminum block 12" x 12" x 1".

After exposure the chips are read on an Eberline Instrument Corporation Model TLR-6 reader. The system employs a preheat cycle which removes low temperature peaks and integrates and digitizes only the light output in a selected temperature range.

18

The dose is calculated from the average light output for the five chips and the statistical uncertainty is the standard deviation of the five readings.

Control badges are used to detect any unusual exposure to the badge which might occur during shipment *

QUALITY ASSURANCE PROGRAM A. Design of Plan Quality of product or service has always been a primary key to in-crease is sales, customer satisfaction, and profit. The management of

-: Eberline Instrument Corporation recognizes the*ever increasing demand for higher quality and reliability for services related to protection of workers and the environment. It is our firm belief that in order to judge the worth of a support service, one must know the philosophy behind it. Eber-line will provide only those services for which it is qualified and these will be provided in a manner that is reliable, with a quality assurance program that maintains a high degree of client confidence. This quality assurance program has been prepared consistent with the following specifications, per the.Technical and Quality Assurance Requirements for Special Purposes.

ANSI-N45&2, American National Standards Institute NRC Branch Technical Position of November 1979 NRC Regulatory Guide 4.15,. Revision l of February 1979.

B. Intercomparison Program Results of Eberline's Midwestern Facility participation in the USEPA's Crosscheck Program will be included in the monthly reports provided to the

- . ~ client. Other intercomparisons in which we routinely participate include:

Environmental Protection Agency Environmental Measurement Lab DOE Quality Assessment Program Battelle Northwest Laboratories IAEA Analytical Quality Control Service US National Buraau of Standards Eberline's Albuquerque Laboratory.

Each of the laboratory managers is responsible for preparing soikes and blanks to be run routinely. Every tenth sample is a spike, a blank, or a split sample.

Regular QC reports are prepared by the laborary manager on a monthly 20

schedule and forwarded to each client. Each report routinely incluaes:

results from EIC interlaboratory comparison, results from EPA Crosscheck program, and results from other intercomparison programs.

Results are reviewed by the laboratory manager. If a problem_ is in-dicated by the data, the nature of the problem is investigated and corrective steps taken immediately. A copy of each report is also provided to the Quality Assurance Manager of the Nuclear Services Division.

C. Quality Assurance Plan The Quality Assurance Program follows the requirments of Company and Division Manuals. The discussion* below outlines Quality Assurance Programs as conducted in the laboratory and as required in our QA Manual.

Procedure Approval Each procedure goes through a vigorous evaluation and review pcocess before it is incorporated into the EIC Procedures Manual. Established pro-cedures of the Environmental Protection Agency (EPA) or the Environmental Measurements Laboratory of the US Department of Energy (EML) are used unless thorough testing has demonstrated that an alternate procedure is equal to or better than the EPA or EML procedure. Uniform procedures are used at both laboratories to the fullest extent possible, except when deviations are necessary to meet the specific requirements of the client. The man1ger of each laboratory and the quality assurance manager review and approve signif-icant procedural changes before they are implemented.

Equipment Calibration and Maintenance Equipment used for qualitative or quantitative measurements is care-fully calibrated and maintained with records of each calibration or main-tenance action kept in appropriate logbooks. To the extent possible, certified standards are used for all primary calibrations. The following standards are used for the application indicated:

21

Measurement Calibration Standard Solution of Standard 137 cs certified by NBS or

. ' Gross Beta Amersham Searle Tritium Solution standard of 3H certified by NBS Gamma Solution standards of various gamma emitters Spectrometry certified by NBS or Amersham Searle. Standards are used to calibrate each counting geometry used.

Results of all the analyses for January through December 1982 are presented in full in Section 5, Data Tables pages.

Table 4 sum.arizes the range and average concentrations for measure-ments at the indicator and control locations with the highest annual mean.

Environme~tal monitoring results showed that the radiation dose to a mem-ber of the general population did not.exceed Technical Specifications of 1% of the 10 CFR 20*limit during 1982.

Specific findings for the various environmental media are discussed below:

AIR PARTICULATE SAMPLES Atmqspheric particulate matter at a field location is accumulated for a one-week period on a glass fiber filter using a low-volume air sampler at a collection.. rate of one cubic foot per minute. This particu-late matter contained on the filter is counted for beta activity in a low-background counting system after the short-lived naturally-occurTing radon and thoron daugh.ters have decayed.

The gross beta particulate data obtained during the year 1982 remained at low levels and were considerably lower than the levels obtained in 1981(1).

The average gross beta concentration for the year for all indicator 3

stations was 0.04 pCi/m , and for the control location it was also 0.04 pCi/m3. Data for analyses of individual filters are given on pages 39'-'

through 44 in section 5.

The gross alpha concentrations for the indicator and background stations remained at or below the detection limit 0.01 pCi/m3

• The gamma spectrometry data of quarterly composites of air particu-late filters begins on page 45. The gamma emitters for the indicator and background stations remained below the detection limit of 0.01 pCi/m3.

The I-131 levels for the indicator and background locations remained at or below the.detection limit of 0.07 pCi/m3, except for a sample collected at Surry Station on 4/19-20/82. Small but detectable I-131 concentration of 0.10 pCi/~3 was measured-and confirmed. No satisfactory explanation is available except that the Surry Station samples is located within the.plant and i~ not an environmental location.

l ENVIRONMENTAL DOSIMETRY.

Measurements of environmental dose rates were made at 43 locations on a quarterly basis .using thermoluminiscent dosimeters (TLDs). The results are tabulat~d on pages 46 through 47, of Section 5 *

. As observed in previous years, the Surry Station location displays clearly elevated dose* rates throughout the year. Other--on-site locations appear to b*e only very slightly *above neariiy locations and the badge~

located near the station intake and discharges consistently give some of the lowest readings observed.* The major fraction of the dose at the Surry Station location is undoubtedly due to operation of the station. The doses at other on-site J..ocations may be partially due to the station, but only by a few tenths of a millirem per week at most. Doses due to the plant at locatiQns away from the site,:tf they exist:, aremasked,by*doses f-rom the natural environmental sources such as uranium,. thorium, and their daughters, and possibly worldwide fal;oi.:;~. .. Anomalous readings were observed at 2 locations during the year. First quarter TLD reading for Lee Hall (35) was high compared to the readings for the same location normally encountered.

It may be possible that TLD badges contained chips that may have been damaged or defective as indicated by the large error term: associated with the data.

At Surry Station the 3rd quarter badge remained at the location during 3rd & 4th quarter, resulting in higher reading (factor of about 2) for the 4th quarter badge and a lower reading for the 3rd quarter badge.

PRECIPITATION SAMPLES Precipitation samples collected at the surry station and at Newport News are analyzed on a monthly basis and as quarterly composites for gross beta depositions and tritium concentrations. Data are summarized on page 49 of section 5.

Gross beta measurements, the only measurement other than tritium re-quired on these samples, are not capable of indicating whether the differ-ences are due to station operations or not. For both the control and the indicator location, the gross beta data obtained during the year were comparable.

The levels in gen~ral were in the range to be expected from measurements of these nuclides in this medium and there are no indications they are attributable to releases from Surry Station *.

The tritium: levels were comparable at both the indicator and control location throughout the year, and were generally in the range to be expect-

. *,,; ed from measurements o.f* this nuclide in this medium. Nevertheless, elevated levels of tritium were found in the sample from Surry Station during Sept-ember and at Newport News during October. However, the measured concentration was still less than O.1 percent of the maximum pe~issible concentration.*

MILK SAMPLES Radionuclides Cs-137 and I-131 were below the detection limits (15 pCi/1 for Cs-137 and 1 pCi/1 for I-131) for all milk samples collected

.during the year. Sr-90 was detected in most of the milk samples in the usual low and variable concentrations t.o be expected. Sr-89 and Ba-La-140 were below ~he de~ection limits (5 pCi/1 for Sr-89 and 15 pCi/1 for Ba-La-140) in all samples collected. Radioactivity attributable to operation: *of Surry Station was not detected in any milk samples collected during the year.

Comparisons of the average conce~trations for all nuclides assayed and other statistical information are given in Table 4 and the data sum-mary on each sample by location are given on pages So through 52 of Section 5.

JAMES*RIVER WATER SAMPLES

~amples of water from the James River are collected bi-monthly from five locations including' the station inlet and discharge and are analyzed (31)

for gamma emitters. Semi-annual composites of the collections from the Chickahominy and Newport News locations are also analyzed to tritium.

Samples collected monthly from the discharge and Scotland Wharf are split with a state agency and are analyzed for tritium, Sr-89/90, and gamma emitters.

Analytical data are presented on pages 53 through 56 of Section 5.

Gamma emitters were below the detection limits of this program in all samples collected.

The concentrations of Sr-90 were below.the detection limit for the two locations* analyzed during the year.

The monthly tritium concentrations for the year for discharge samples ranged from 400 to 910 pCi/1; the average being 753 pCi/1.

The tritium concentrations for Scotland Wharf ranged from 700 to 910 pCi/1, the average concentration being 837 pCi/1. There was no statis-tically significant difference in average concentrations between indicator and control locations.

• Tritium levels in the semi-annual composites for Chickahominy and.

Newport News were slightly above the detection limit of 330 pCi/1. These levels were in the range to be expected from measurements of this nuclide in this medium.

CLAM SAMPLES Clam samples are collected bi-monthly from five locations near the station including the station discharge and are analyzed for gamma emit-ters. Samples from the station discharge are frequently designated as "State Split Samples" and such samples are analyzed for Sr-89 and Sr-90 as well as gamma emitters.

(32)

i The gannna emitters were below the detection limit for all samples analyzed during the year.

Analysis of state split clam samples for radiostrontium revealed the presence of only Sr-90 at levels attributable to world wide fall-out in two samples.

Analytical data are presented on pages 57 1nd 58 of Section 5.

OYSTER S.AMPLES Samples of oysters are collected from Deep Water Shoal, Point of Shoal, and Newport News on a bi-monthly basis and analyzed for gamma emitters~ Analytical data are presented on page 59 of Section 5.

Gamma emitters were below the detection limits of the program in all samples collected throughout the year.

FISH S.AMPLES Fish samples are collected in the vicinity of the station twice a year and _analyzed for gamma emitters. Data are presented on page 60 of Section 5.

Gannna emitters were below the detection limits of the program specifications.

CRAB SAMPLES Samples of crab from the vicinity of Surry Station are collected during the summer months and analyzed for gamma emitters. The gamma emitters were below the detection limits of the program and are listed on page 60 of Section 5.

(33)

t SILT SAMPLES Silt samples were collected three times during 1982 from six loca-tions (five indicator and one control location) and analyzed for gamma emitters. Silt is one of the few environmental media in which rad~.o-active effluents from nuclear power stations are usually detected.

Traces*of Cs-137 were found in most samples. The presence of this nuclide is attributed to world wide fallout from atmospheric nuclear test. Several indicator samples also contained Co-60 and Cs-134 above the detection limit. Their presence could be due to station operations. Data are summarized on page 61 of Section 5.

SOIL SAMPLES Soil samples are collected annually from six locations and analyzed by gamma spectrometry for gamma emitters.

The only nuclide detected at concentrations greater than the detection limit for the program was Cs-137. The concentrations of Cs-137 have been quite variable throughout the years L~ is illustrated in the table below. This is probably due to the well-recognized difficulty of obtainingtruly representative samples of soil. Modified sampling techniques by station personnel appear to have elimated this problem from 1978 to the present. There are no clear trends and the origin of the cesium is unclear.

Long and short term world wide fallout are probably the major factors but contributions to the total by the station cannot be ruled out. If, however, the major fraction were due to the station, sig-nificant amounts of Cs-137 and Co-60 might be expected in the samples, but this is not the case. Detailed analytical data are presented on page 62 of Section 5.

FOWL SAMPLES A canadian goose from the Hog ~sland Reserve was collected in March and a fowl was obtained from the same area in September. They were analyzed for gamma emitters; specifically for Cs-134 and Cs-137. Con-centrations of these nuclides were below the detection limit of 80 pCi/kg for both samples. Data are given on page 62 of Section 5.

CROP SAMPLES Samples of food crops (kale, cabbage, corn, peanuts, and soybeans) were collected from four area farms in 1982 and analyzed from gamma emitters, Sr-89 and Sr-90. Gamma emitters and Sr-89 were below the detection limits of the program.

Sr-90 was detected in most of the samples in low and variable con-centrations. Long and short term world wide fallout deposits are probably the reason for this.

The results are tabulated on page 63 of Section 5.

(35)

WELL WATER SAMPLES Samples of water were collected from each of four wells (three indicator and one control location) once in April and once in October.

These were analyzed for gross alpha, gross beta, and tritium.

Gross alpha and beta activity were detected in most of the samples at the usual low levels encountered in environmental media. There was no statistically significant difference in concentrations, which were similar to those measured previously, between indicator and background stations and the activity is attributable to naturally occurring*nuc-lides.

Tritium concentrations were at or below the detection limits in samples collec_ted during the year.

Analytical data are given on page 64 of Section 5.

SURFACE WATER SA.1'1PLES Surface water samples were collected in April and October from each of four locations. They were analyzed for gross alpha, gross beta, and tritium.

Gross alpha levels were below the detection limit for all samples analyzed. Gross beta levels were all at the low concentrations usually expected to be found in environmental surface water, with no significant differences between indicator and background stations or concentrations measured in the previous years.

Tritium concentrations were at the detection limits of the program in spring collections, and below the detection limits in the fall. The levels of tritium measured were comparable at both indicator and back-ground locations, and were generally in the range to be expected from measurements of this nuclide in this medium.

Data are presented on page 64 in Section 5 (36)

J INTRODUCTION TO THE DATA TABLES The following information will be helpful in understanding the presentation of the data in the tables in this section.

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 soil 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° for about 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />.

pCi/m 3 a reporting unit used with air particulate and radioiodine data which refers to the radioactivity content 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.

Gamma Emitters samples were analyzed by high resolution (GeLi) gamma or spectrometry. The resulting spectrum is analyzed by a Gamma Isotopic computer program which scans from about 50 to 2000 kev and lists the energy peak of any nuclides present in concentra-tions exceeding the sensitivity limits set for that particular e."'Cp erimen t.

NA, NS, NR used in place of a concentration when a sample was not available (NS), or when a sample was not analyzed for some specific measurement (NA), or when an analysis is not required (i.-TR.;

Error Terms figures following 11 +/-11 are error terms based on counting uncertainties at the 2cr (95% confidence) level. Values pre-ceded by the"<" symbol were below the stated concentration at the 3cr (99% confidence) level.

Exponents E."'Cponents necessary to prevent data tables from being cumbersome are handled in the conventional manner of including them in the colUillil headings.

Sensitivity In general, all analyses meet the sensitivity requirements of the program as given in Table 3. For the few samples that do not (because of inadequate sample quantities, analytical interferences, etc.) the sensitivity actually obtained in the analysis is given.

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.
