INTRODUCTION The Surry Power Station of Virginia Electric and Power Company consists of t-wo Westinghouse pressurized water reactors each with a generating capacity of 788 }Il-IB. 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 hc1s 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 Regula~ions 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 3 summar-izes the results of the radiological environmental surveillance measurements during ~2.lendar year 19 79.

SUNMARY 1979

. 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 1979.

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 3 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)

S?ecific findings for various environmental media are discussed below:

AIR PARTICULATE SAMPLES Tne average concentration for the year for all indicator stations was 0.04 pCi/m3, and for the control location it was 0.04 pCi/m3

  • Data for

. analyses of individual filters are given on pages 2-1 through 2-6 of Appendix I.

Gamma spectrometry of quarterly composites of air particulate filters indicated that concentrations.of Cs-134 and Cs-137 were below 0.01 pCi/m3 throughout the year.

Small amounts of Co-60 were detected in the fourth quarter coc!:posite from five inciic.ator locations.

Analytic2.l data are gbren on page 2-7 of Appendix I.

ENVIR01~IB~'TAL DOSIMETRY Measurements of environmental dose rates were made at twenty-three locations plus a control (shielded) location on a quarterly basis using thermoluminescent dosimeters (TLDs).

1. 0+/-0.1 0.8+/-0.2 O.S+/-0.2 1.0+/-0.l 0.9 As observed in previous years, the Surry Station location displays clearly elevated dose rates throughout the year.

Other on-site locations ap?ear to be only very slightly above nearby locations and the badges lo.:.:at::d. near c.:v:: si:atior.. intake and cl_ischarges consi.st~i::t2.y give sone of the lo:;2s~ re2dj~~s observed.

The major fraction 0£ the 6ose at the Surry S=~t~on lccation ~s undoubtedly due to oper~tion c~ the station.

The doses 13

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, it 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 deposition and tritium co"ncentrations.

Data are summarized in Table 3 anion page 2-8 of Appendix I.

Gross beta measurements, the only measurements other than tritium required on these samples, are not capable of indicating whether the dif-ferences are due to station operations or not.

Cross beta and tritium concentraticr.s in precipitation were comparable at.both-l-0cations throughout the year, and were generally in the range to be expected. from measurements of these nuclides in this medium.

The_ cause of the somewhat elevated tritium concentrations in May and August are unknown to us, but the increase was observed at both locations, suggesting that it is due to large scale meteorological processes and not releases from Surry Station.

MILK SA.}.{PLES Rz.dionuclides Cs-137 anc 1-131 were below th~ detectior. limits (15 pCi/1 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 E1::-::...a-140) in all sanr;:ile.s c:oll2c':sc.

R.s.dioactivity attributable to operation of Surry Staticn was r.ot de-14

-:-.- -1 tected in any milk samples collected during the year.

Comparisons of average concentrations for all nuclides assayed and other statistical information are given in Table 3 and data for analyses on each sample are given on pages 3-1 through 3-3 of Appendix I.

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.

Quarterly samples are collected from the discharge.

These samples are split with a State a9ency and are analyzed for tritium and sr....:89/90 in addition to gamma emitters.

fi.nalytical data are presented on pages 4-1 through 4-3 of Appendix I and are summarized in Table 3 of this report.

Sr-89 and Sr-90 were below t:he detection requirements of this program in all samples collected.

Tritium was detected in all of the Station Discharge (State split) samples and they were in the range frequently encountered in environmental surface water.

Tritium in the semi-an.~ual composites from Chickahominy and Newport News was below the detection limit of 330 pCi/1 for both halves of the year.

Small amounts of Cs-137 were detected in only one sample that was collected in January.

It does not clearly indicate radioactive release f"!'o2 -che statiort..

Analysis of State split clam samples for radiostrontium revealed the presence of only Sr-90 at levels attributable to worldwide fallout in one sample (November) *

.Analytical data are presented on pages 4-4 and 4-5 of Appendix I and Stll!:!!larized in Table 3.

OYSTER SAMPLES Samples of oysters are collected from Deep Water Shoal, Point of Shoal, and. 1:;ewport News on a bi-monthly basis and analyzed. for gamma e.w.i t te::-s.

So*ma of the collections from Newport News were designated State split samples.

Data presented on page 4-6 of Appendix I show that concentrations of gam.T.a emitters were below the LLDs of the program throughout the year.

FISH. SAMPLES Fish are collected from the vicinity of the station twice a year and analyzed for gamma emitters by gamma spectrometry.

Cs-137 and other gamma emitters were below the LLDs for the program in all samples collected during the year.

Data are presented on page 4-7 of Appendix I.

CRAB SAMPLES Samples of crabs from the vicinity of Surry Station are collected in July, August, and September.

Results of analyses on each of the collections the LLDs for the program in all samples.

and several contained Co-60 above the LLDs.

The levels of activity meas-ured are generally comparable with those encountered in previous years.

Precise comparison cannot be made because of the variability of concentra-tions at a given location and the relatively infrequent collections.

Data are summarized in Table 3 and detailed in Appendix I, page 4-8.

SOIL SAMPLES Soil samples are collected annually fro~ six locations and analyzed by gamma spectrometry for gamn.a emitters.

The only nuclide detected at concentrations greater than the LLDs for the program was Cs-137.

The con-centrations of Cs-137 have been quite variable th~oughout the years as is illustrated in the table below.

this is probably due to the well recognized difficulty of obtaining truly representative S21!1.ples of soil.

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 con~ributions 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 ~ase.

De-tailed analytical data for the current year's SB.!:lples are found on page 5-1 of Appendix I *.

Great Blue Heron was obtained on Hog Island Point in September.

The fowl were analyzed by spectrometry for gamma emitters, specifically Cs-134 and Cs-137.

Concentrations of these nuclides were below the LLD of 80 pCi/kg for both samples.

Data are given on page 5-1 of Appendix I.

CROP SAMPLES Samples of food crops (corn, peanuts, soybeans) are collected from two farms in the area annually and analyzed for gamma emitters, Sr-89 and Sr-90.

Sr-90 was detected in most of the samples in low and variable concentrations.

Long and short terril. worldwide fallout deposits are probably the reason for this.

Sr-89, Cs-134, Cs-137, and other gamma emitters were below the detection limits.

Data are given on page 5-1 of Appendix I.

WELL WATER SAMPLES Samples of.water were collected from each of.four wells once during the Spring and once in the Fall.

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 back-ground stations and the activity is attributable to naturally occurring nuclides.

Tritium concentrations were below the detection limit of 330 pCi/1 in all samples collected during the. year.

Analytical data are given on ;iage 5-2 (Appendix I) and summarized in Table 3.

SURFACE WATER SAMPLES Surface water samples were collected in the Spring and Fall from each of four locations.

Gross alpha and gross beta concentrations were a~l sr che. low concentrations usually expected to be found in environ~e~ta~ ~~

face water, with no significant differences between indicator and bad:-

1S

ground stations or concentrations measured during 1978.

Tritium at typical environmental levels was detected in the Fall season samples but was below the minimum detection levels in the Spring samples.

The tritium in the Fall samples is attributable to.the normal environmental level fluctuations and not operation at nuclear power stations.

Average concentrations for indicator and background stations are given in Table 3, and analytical data for all samples are given on page 5-2 of Appendix I.

Ai.~ALYTICAL 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. DOE *c1) or those of h

(2) t e Federal E. P.A.

Brief descriptions of analytical procedures are available in the Labor-atory Procedures Manual available at Surry Station and in 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. Filters are counted long enough to ensure that the required sensitivity (LLD) will be met.

Gamma Isotopi~ - 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 program sensitivity (LLD) is met. (See also intro. to.data tables, Appendix I).

Water Samples (including surface, well, James River waters and precipitation).

Gross Beta -

a measured aliquot of sample is digested, *11wet-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.

GalllI!'.a 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 ensur.e meeting the sensitivity requirements of the program. See also the Introduction to Data Tables.*

Strontium-89 and_Strontium-90 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 1 next put into solution, carrier yttrium added, and the strontium and yttrium fractions separated. The yttrium is counted and-Trom-th~---

(Sr-90 daughter) count, the sr~9o concentration can be.determined. The difference between the total strontium concentration as determined by the equilibrium ~aunt 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 t*wo points during ingrowth of the Sr-90 daughter Y-90. l-fuile 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

'v500 pCi/1) the sample is distilled,mixed with the appropriate counting phosphors,and counted with no further treatment. If higher sensitivity is required (ie. ('v300 pCi/1) the sample is isotopically enriched in tritium concentration prior to liquid scintillation counting.

21

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

Milk Samples

~

- measured amounts of carrier iodide are added to *a known *-:volume of milk and the iodine extracted on anion exchange resin. The ~odine.

is recovered and nurified 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 ?liquot 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 requi~ed 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 ash is dissolved and the solution treated from this point on in the same manner as are water samples (Q.v.).

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

Gamma Isotopic 1'.n.a.ly,,:...s -

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).

22

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 ashed sample is then dissolved 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 piec~s 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 ba~ges comprizing five, chips sealed in plastic protective holders having a density of 50 mg/cm2

  • The TLD chips are 1/8" 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 ~00°c and immediate cooling to ambient temperature by placing the tray containing the annealed chips on an aluminum block 12" x 12" x l".

After exposure the chips are read on an Eberline Instrument Corporation Model TLR-5 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.

23

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.

1.

Error Terms Data preceded by the "less than" symbol (<) are at the 3cr (99% confidence) level. The error terms on other da_ta are 2cr (95% confidence).

  • 2. Sensitivities - LLD's

.Analytical sensitivities or LLD's (Lower Limits of Detection) are those given in the most recent NRC Branch Position on Regulatory Guide 4.8.

(Table A)

For analyses not required in RG. 4.8, Federal EPA, former requirements for similar programs, or other appropriate guides are used (Table B). The LLD's are calculated as per RG. 4.8 at the 3cr level.

The Guide specifically states that the LLD's are~ priori not~ posteriori; limits for a particular measurement. When, however, RG. 4.""B""or other LLD's have not been achieved, a footnote giving a brief explanation has been inserted.

3.

Gamma Isotopic.Analyses All samples to be analyzed for gamma emitters are assayed using high resolution gamma spectrometers. (Geli). The spectra are computer scanned using recognized programs. The energy search.programs specifically examine the peak areas of gamma energies for the expected effluents from nuclear power plants. Only the nuclides required by NRC Reg. Guide 4.8 are reported in the Data Tables. If other gamma emitters associated with either power station operation or worldwide fallout from nuclear weapons tests are detected, this information is either given in dis-cussions of the data or entered as footnotes to the data tables.

Naturally occurring gamma emitters are frequently detected in env"iron-mec1.tal samples. Analyses of these nuclicies is not requ:.r2.d by the ~RC and they a:?:"e neith'=::* quantified,,*he:-, det':?.c-::.-2.d aor rep.:.;rted in.::r:e Data Tables.
