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 Pro_gram for the period 01 January 1980 through 31 December 1980.

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 1980. ,.

INTRODUCTION

'!'he Surry Power Station of Virg.inia 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 controlor background locations and analyzed_ to determine if changes in radioactivity levels may bti attributable to the operation of the station. This environmental radio-

logical monitoring progrrim 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 freqcent collecliun and unalysis of certain samples than called for in the Technical Spccificntions. The accompanying map shows the plant environs. Table izes the results of the radiological environmental surveillance measurements during calendar year 1980.

SUMMARY

1980

.,

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 1980.

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 mo~t signif~cant 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 sour:ce 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 l~cations, 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

- !

All samples are collected by VEPCO Environmental Services Personnel and shipped to the Eberline laboratory in West Chicago, Illinois.

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 .1 lists the sampling locations and frequencies. Figure 1 I

shows the locations.of the various sampling environs.

SECTION 3 ANALYSIS PROGRAM 10

~I

Table 2 lists the sample analysis prpgram - 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 3cr level.

The Guide specifically states that the LLD'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 (1) to, and in most cases, identical with, those of the U.S.D.O.E. 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 proportional 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 - Quar.terly composites of air particulate filtecs are counted in high resolution (GeLi) gamma spectrometers for periods of time loµg enough to ensure that the required program sensitivity (LLD) is met. (See also introduction to data tables, Section 5.)

Water Samples (Includes Surface, We~l, 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.

Office of Research and Development, Las Vegas, Nevada 89114.

Gamma Isotopic - a measµred 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 Introduc~ion to Data Tables.

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 1

method). The chemic al 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 tot~l. Sr count). The strontium is next put-into solution, carrier yttrium added, and the strontium and

-

yttrium fractions separated.*The yttrium is counted and from the Y-90 (sr~9o daughter) count,. th_e sr-.:..90 concentration can be .determined. The differenc*e between .the* total strontium concentration as determined by the equilibri~m 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

~soo pCi/1) the sample is distilled, mixed with the appropriate counting phosphors and counted with no further treatment. If higher sensitivity is required (ie. <~300 pCi/1) the sample is isotopically enriched in tritium concentration prior to liquid scintillation counting.

• Isotopic enrichment is done by the classical method of Ostlund w~ich 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 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 'Sa,mple 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 requ1red 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°cJ. The ash is dissolved and the solution treated from this point on in the same manner 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, plnced in a controlled Rcomctry 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).

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 ~ I of the sample and the sample is ashed at high temperature (>700°c). The ashed sample is then di~solved and processed in the same manner as are water or milk samples.

Soil and Silt Samples Gamma 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 five ,'

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

• The TLD chips are 1/8 11 x l/8 11 x 1/32 LiF (thallium activated) known commc".'cially as Harshaw-100. The chips are all selected to provide uniform response to with-in 5% of th~ 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 11 x l".

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 pea~s 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 ke~ 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 orde: 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 reiiable, with a quality assurance ~rogram 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 1~79.

NRC Regulatory Guide 4.15, *Revision 1 of February 1979.

n. lntercomparison 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:

I Environmental Protection Agency Environmental Measurement Lab DOE Quality Assessment Program Battelle Northwest Laboratories IAEA Analytical Quality Control Service US National BurCUJu of Standard~

Eberline'& Albuquerque Laboratory.

Each of the laboratory managers is responsible for preparing &Pikes 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 includes:

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 (E}.lL) are used unless

• • thorough testing has demonstrated that an alternate procedure is equal to or better than the EPA or EML procedure. Uniform procedures arc used at both laboratories to the fullest extent possible, except when deviations are necessary to meet the specific requirements of the client. The ma~Jger of each laboratory and the quality assurance manager review and approve signif-icant procedural changes before they arc implemented.

Equipment Calibration and Maintenance Equipment usc<l for <1uulitativc or quantitative 111casurco1<.mls is care-fu) ly calibrated and maintained with records of each calibration or main-terancc action kept in appropriate logbooks. To the extent possible, cettified standards are used for all pri1;Dary calibrations. The following standards are used for the application indicated:

Results of all the analyses for January through December 1980 are presented in full in Section 5, Data Tables pages 40 through 65.

Table 4 summarizes the range and average concentrations for me~sure-ments at the indicator and control locations wi~h the highest annual mean.

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 1980.

Specific findings for the various environmental media are discussed

AIR PARTICULATE SAMPLES Atmospheric 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 th~ short-lived naturally-occuring radon and thoron daughters have decayed.

'

The average gross beta concentration for the year for all indicator stations was 0.04 pCi/m 3 , and for the control location it was 0.05 pCi/m 3

• Data for analyses of individual filters are given on pages 40 through 45 in Section 5. Small elevations in the gross beta activity for all locations during December is attributed to atmospheric fallout.

The gross alpha concentrations for the indicator and background stations remained at or below the detection limit of 0.02 pCi/m 3

• ENVIRONMENTAL DOSIMETRY Measurements of environmental dose rates were made at 54 locations in the first quarter and at 43 locations in the remaining quarters of 1980.

The results are tabulated on pages 62 through 65 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 be only very slightly above nearby locations and the badges located near the station intake and dischai::ges consistently give some of the lowest readings observed. The.major fraction of the dose at the Surry Station* *1-ocation is undoubtedly. due to operatiol) of the station. The doses at other*-on:..site locations 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 locations away from the site, if they exist, are masked by doses from the natural environmental sources such as uranium, thorium, and their

\

daughters, and possibly worldwide fallout.

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 in page 47 of Section 5.

Gross beta measurements, the only measurement other than tritium required on these samples, are not capable of indfcating whether the differences are due to station operations or not. The gross beta levels at the control location were higher in the first and second quarter, compared to the indicator location. The levels in general were in the range to be expected from measurements of these nuclides in this medium and does not indicate to be attributable to releases from Surry Station.

The tritiLtJil levels were comparable at both the indicator and control*location throughout the year, and were generally in the range to be expected from measurements of this nuclide in this medium.

MILK SAMPLES Radionuclides Cs-137 and I-131 were below the detection limits (15 pCi/~ for Cs-137 and 1.0 pCi/1 for I-131) for all milk samples collected during the year. Sr-90 was detected in the usual low and variable concentrations to be expected in most of the milk samples collected during the year. Sr-89 and Ba-La-140 were below the detection limits (5 pCi/1 for Sr-89 and 15 pCi/1 for Ba-La-140) in all samples collected.

'

Radioactivity attributable to oper~tion of Surry Station was not detected in any milk samples collected during the year.

31

Comparisons of the average concentrations for all nuclides assayed and other statistical information are given in Table 4 and the data aummary on each sample by location are given on pages 48 through 50 of Section 5.

• JAMES RIVER WATER SAMPLES Samples of water from the James River are collected bi-monthly from five locations including the station inlet and discharge and are analyzed for gamma emitters. ,Semi-annual composites of the collections from the Chickahominy and Newport News locations are also ,analyzed for tritium.

Samples collected quarterly from the discharge are split with a state agency and are analyzed for tritiup1~ Sr-89, Sr-90~ and gauuna emitters.-

Analytical data are presented in pages 51 through 53 -t:Jf Section 5.

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

Sr-89, Sr-90, and tritium were below the detection limits in all of the station discharge (State Split) samples.

Tritium levels in the semi-annua~ composites for Chickahominy and Newport News were slightly above the detection limit of 3~0 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 emitters.

32

Samples from the station discharge are frequently designated "State Split Samples" and such samples are analyzed for Sr-89 and Sr-90 as well as gamma emitters.

- '

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

Analysis of state split clam samples for radiostrontium revealed the presence of only Sr-90.,at levels attributable to world-wide fallout in one sample (November).

Analytical data are presented in pages 54 and 55 of Section 5.

OYSTER SAMPLES 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 in page 56 of Section 5.

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

FISH SAMPLES Fish samples are collected in the vicinity of the station twice a year and analyzed for gamma emitters. Data are presented in pag~ 57 of Section 5.

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

CRAB SAMPLES Samples of crab in the vicinity of Surry Station are collected in September and analyzed for gamma emitters. The gamma emitters were below the detection limits of the program and are listed in page 57 of Section 5.

SILT SAMPLES .

Silt samples **are ~ollected semi-annually from six locations._{ five indicato,; and one control location) and analyzed for gamma emitters.

Silt is one of the few environmental media in which radioactive -effluents *<*

from nuclear power stations are usually detected.

Most of the samples collected contained measurable concentrations of Cs-137 and one indicator sample contained Co-60 above the detection limit. The levels of activity measured are generally comparable with those encountered in the previous years. Co-60 presence could be due to station operation. Data are summarized on page 59 of Section 5.

SOIL SAMPLES Soil samples are collected annually from six locations and analyzed by gamma spectrometry for gamma emit~ers *

.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 th9ughout the years as is illustrated in tile table below. The is probably due to the well recognized difficulty of obtaining truly representative samples of soil. Modified sampling techniques by station personnel appear to have eliminated this problem

\

from 1978 to 'the present. There are no clear trends and the origin of the cesium is unclear.

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

FOWL SAMPLES A Mallard duck from the Hog Island Reserve was collected.in March and a coot was obtained from the*same location in October. They were analyzed for gamma emitters, specifically for Cs-134 and Cs-137.

Concentrations of these nuclides were below the detect.ion limit of 80 pCi/kg for both samples. Data are given in page 60 of Section 5.

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

!ir-90 was detected in most of the samples in low and variable concentrations. Long and short term worldwide fallout deposits are probably the reason for this.

The results are tabulated in page 60 of Section 5.

WELL ~'ATER SAMPLES Samples of water were collected from each of four wells (three indicator and one control location) once in April (spring) and once in October (fall). 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 occuring nuclides.

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

Analytical data are given in page 58 of Section 5.

SURFACE WA!ER SAMPLES Surface water samples were collected in April (spring) and October (fall) from each of four locations. They.were analyzed for gross alpha, gross beta, and tritium.

Gross alpha and .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 above the detection limits of the program both in spring and fall collections. The fall collections were somewhat higher than the spring collections. The levels of tritium measured were comparable at both indicator and background locations, and were generally in the.range to be expected from measure-ments of this nuclide in this medium.
