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 iocations 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 I and II 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 III summar_~

izes the results of the radiological environmental surveillance measurements during calendar year 1978.

Sl:r-!ARY 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 1978.

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 .

  • A nuclear explosive was detonated in the atmosphere in the People's*

Republic of China in mid-March of 1978. Radioactive debris (fallout) from this event was detected throughout the continental United States in the later part of March chiefly as I-131 in milk samples and elevated concentrations of beta and gamma emitters in air. particulate filters collected during the fol-lowing several months. Effects on other media were generally minimal or masked by the usual ambient levels encountered in those media. A second nuclear device was exploded in mid-December at the Lop Nor test site.

Fallout from this event was apparently too diffused to be detected in routine environmental monitoring progr*a!!ls.

Table III summarizes the range and average concentrations for me&sure-ments at the indicator and control locations, and the location with the high-

~st annual mean. Complete information is given in the Sample Data Tables.

(Appendix I)

Specific findings for various environmental media are discussed below:

12

Air Particulate Samples Air particulate samples collected in late March showed the arrival of fallout associated with the nuclear test conducted by the People's Republic of China. All sampling locations showed increased gross beta concentration, with elevated levels persisting until late July. The average concentration for the year for all indicator stations was 0.11 pCi/m 3

  • and for the control location was 0.13 pCi/m 3
  • The single highes*t concentration, 0.66+/-.09 pCi/m 3 , was noted at Newport News on 04/11/78, and is attributable to fallout and not operation of nuclear power plants.

The presence of significant and variable amounts of radionuclides due to fallout in this and previous years' samples does not permit meaningful trend analysis or comparison of average concentrations in the samples. Data for analyses of individual filters are given on pages 2-1 through 2-3 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/m 3 throughout the year. Small amounts of Ce-144 and occasionally Ru-106 were detected in first and second quarter composites from all locations. These nuclides were found to be present in similar collections throughout the continental U. S. and are attributed to fallout from the Spring Chinese nuclear test. By the third quarter of the year, concentrations of all gamma emitters had fallen below LLD's for the most part. None of the radioactivity detected is attributable to operation of Surry Station, since effects of the station, if any, are masked by the more abundant fallout. Analytical data are given on page 2-4 of Appendix I.

14

Other on-site locations appear to be only very slightly above nearby locations and the badges 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 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 usual natural environmental sources such as uranium, thorium and their daugh-ters, and possibly worldwide fallout .

. Precipitation Samples Precipitation samples collected at the Surry Station and at Newport News. The samples are collected and analyzed on a monthly basis and as quarterly composties *for gross beta deposition and tritium concentrations.

Data which are summarized in Table III and on page 2-5 of Appendix I. Some samples collected at the Surry Station displayed gross beta deposition slightly higher than the Newport News location especially during the first half of the year. Gross beta measurements, the only measurements other than tritium required on these samples are not capable of indicating whether the differences are due to station operations or not. Some if not most of the activity during the first half of the year is due to worldwide fallout from both the well-known "Spring Peak" which is due to injection of long term radioactive debris from the stratosphere into the troposphere during early part of the year, and the Chinese nuclear test previously referred to.

Tritium concentrations in precipitation were comparable at both loca-tions throughout the year, and were generally in the range to be expected

  • from measurements of this nuclide in this medium.

15

The cause of the somewhat elevated concentrations in the February sample is 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 Samples Radionuclides attributable to worldwide fallout are found in milk samples throughout the country. The most prevalent nuclides are Cs-137 and Sr-90, which were detected in the usual low and variable concentrations to be expected in most of the milk samples collected during the year. Occa-sio~ally, I-131 is detected in milk samples collected for a few weeks after intrusion of debris for an atmospheric nuclear explosion. Such was the case with samples from Judkins, Gwaltney and Smith farms during March, shortly after the April nuclear detonation in the People'~ Republic of.China (see also air particulates). All other milk samples collected during the year were below the de'tection limit (O. 5 pCi/1) for I-131.

Strontium-89. and Ba-La-140 were below the detection limits in all samples collected during the year.

Radioactivity attributable to operation of Surry Station was not de-tected in any milk samples collected during the year. What activity was detected, is due to worldwide fallout and effects of the station, if any, were masked by the more abundant debris from that source.

Comparisons of average concentrations for all nuclides assayed and other statistical information are given in Table III and data for analyses on each sample are given on pages 3-1 and 3-2 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.*

16

Gross alpha and gross 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 *concentration:s, which were simi-lar to those measured previously, between indicator and background sta-tions and the activity is attributable to naturally occurring nuclides.

Tritium was detected above minimum detection limit of 330 pCi/1 in only one sample (Jamestown, 04/11/78, 530+/-110 pCi/1). This concentration is within the range to be expected in environmental samples and is not due to operation of the Surry Plant. The Fall sample from the Jamestown location was below MDL.

Analytical data are given on page 5-1 (Appendix I) and summarized in Table III.

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 all at the low concentrations usually expected to be found in environmental sur-face water, with no significant differences between indicator and back-

. ground stations or concentrations measured during 1977.

Tritium at typical environmental levels was detected in Spring samples, but was below the minimum detection levels in Fall samples. The tritium in the spring samples is attributable to either normal environmental level fluctuations or fallout from recent atmospheric nuclear explosions and not operation at nuclear power stations.

Average concentrations for indicator and background stations are given in Table III, and analytical data for all samples are given on page 5-1 of Appendix I.

17

James River Water Samples Samples of water from the James River are collected bi-monthly from five locations including the station inlet and dishcharge 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 agency and are analyzed for tritium, Sr-89 and Sr-90 in addition to gamma emitters. Analytical data are presented on pages 4~1 through 4-3 of Appendix I and are summarized in Table III of this report.

Gamma emitters were below the detection requirements of this program in all samples collected as were Sr-89 and Sr-90 in those samples requiring analyses ~or these latter nuclides.

Tritium was detected in all of the Station Discharge (State Split.)

samples. The April and October samples were in the range frequently encoun-tered in environmental surface water. The January and July samples displayed concentrations somewhat higher than usually expected in the environment. It is possible that these measurements represent releases from the Station.

Tritium in the semi-annual composites from Chickahominy and Newport News was below the detection limit of 300 pCi/1 for both halves of the year.

Silt Samples Silt Samples are collected semi-annually from six locations and ana-lyzed for gamma emitters.

18

Silt is one of the few environmental media in which radioactive effluents from nuclear power stations are usually detected. Most of the samples col-lected contained measurable concentrations of Cs-137, several contained Co-60 above the MDL's, and the Fall sample from the Station Discharge con-tained Cs-134. The Spring sample from the same location was anomalous in that no radioactivity was detected in a sample which is expected to be one of the highest areas. This probably represents a sampling problem rather than an actual "absence" of activity in the area. The levels of activity measured 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 III and detailed in Appendix I, page 4-8.

Clam Samples Clam samples are collected bi-monthly from five locations near the station including the Station Discharge and are analyzed for gamma emitters.

Samples from this location 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 LLD's 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 worldwide fall-out in one sample (May).

Analytical data are presented on page 4-5 of Appendix I and summarized in Table III.

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 .

19

Some of the collections from Newport News are designated State Split samples.

Data presented on page 4-6 of Appendix I show that concentrations of gamma emitters were below the LLD's 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 spectroscopy. A sample of catfish collected in February contained 1. 9+/-1. 6 pCi/kg (wet we*ight) Cs-137. This concentration of Cs-137 is not considered to be especially unusual in bottom feeders. This and other gamma emitters were below the LLD's for the program in other samples of this and other species 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 as given on page 4-7 of Appendix I indicate that gamma emitters were below the LLD's for the program in all samples.

Soil Samples Soil samples are collected annually from six locations and analyzed by gamma spectrometry for gamma emitters. The only nuclide detected at concen-trations greater than the LLD's for the program was Cs-137. Because the sam-ples collected during the scheduled collection yielded unexpected concen-trations of Cs-137, a second series of samples .were obtained and analyzed.

The concentrations of Cs-137 have been quite var~able throughout the years as is illustrated in the table below. This is probably due to the well rec-ognized difficulty of obtaining truly representative samples of soil.

There are no c~ear trends and the origin of the cesium is unclear .

20

Long and short term worldwide fallout are probably the major factors and contributions to the total by the station can not be ruled out. If, however, the major fraction were due to the station, significant amounts of Cs-134 and Co-60 might be expected in the samples, but this was not the case. De-tailed analytical data for the current year's samples are found on page 5-2 of Appendix I.

Crop Samples Samples of food crops (corn, peanuts) are collected from two farms in the area annually and analyzed for gamma emitters, Sr-89 and Sr-90. No radio-activity was detected _in any of the samples at the LLD' s applicable to this program. Data may be found on page 5-2 of Appendix I.

Fowl Samples A Canadian Goose from the Hog Island Reserve was collected in }1arch and a'h American Egret was obtained on Hog Island Point in September. The fowl were analyzed by spectrometry for gamma emi-tters, specifically Cs-134 and Cs-137.

Concentrations of these nuclides were below the LLD of 80 pCi/kg for both -sam-ples. Data are given on page 5-2 of Appendix I .

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. DOE (1) or those of t h e Federal -E. P.A. (2) .

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 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 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, "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 ensur.e meeting the sensitivity requirements of the program. See also the Introduction 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 method). The chemical yield for strontium is determined by atomic adsorp-tion spectrometry or grav_imetric 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, carrier yttrium added, and the strontium and

  • yttrium fractions separated. The yttrium is counted and from the Y~90 (Sr-90 daughter) count, the Sr-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

~soo pCi/1) the sample is distilled, mixed with the appropriate counting phosphors* and counted with no further treatment. If higher sensitivity is r~quired (ie. <~500 pCi/1) the sample is isotopically enriched in tritium concentration prior to liquid scintillation counting.

23

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 uurified 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 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 ash is dissolved and the solution treated from this point on in the same manner as are water samples (Q.y.).

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

24

_ __J

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 te~perature ()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 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 l/8 11 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-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.

25

  • 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 *

1.0 Introduction_ to the Data Tables In this section are given itens of information helpful in under-standing the presentation of the data in the Tables.

1.
  • Error Term!=l Data preceded by the "less than" symbol (<) are at the 3cr (99% confidence) level. The error terms on other data 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 t_he LLD's are~ priori not a posteriori; limits for a particular measurement. When, however, RG. 4.-S-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 nucleaf 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 environ-mental samples. Analyses of these nuclides is not required by the NRC and they are neither quantified when detected nor reported in the Data Tables.

4. Exponents Exponents necessary to prevent data tables from being cumbersome are handled in the conventional manner of including them in column headings .
