)J IN'TRODUCTION ne North Anna Power Station consists of two pressurized water reactors of 947 megawatts located in Mineral, Virginia. Monitoring of the environment began prior to operation in January of-1977 and has continued to the present. Unit One began operation in April 1978; Unit Two reached full operation in December 1980.
Outlined in this document is the description of the radiological environ-mental monitoring program conducted by Virginia EJ ectric and Power Company for the No:th Anna Power Station, and a summary of the data generated to satisfy the monitoring requirements. This program is based on the technical specifications requiring the collection and analysis of various sample media to provide information on the type and quantity of radioactivity in certain indicator organisms or critical pathways. Virginia Electric and Power Company is responsible for the co11cetion of the sampics required for the program and Teledyne Isotopes is responsibic for the analysis of each sample and submission of the reports of analyses. A quarterly summary of the data reported for each sample type is appended to this document for the period of January 1,1951 through March 31, 1981. nis quarterly data summary includes a summary of the radioactivities O reported for each sample type and pathway and a tabulation of the mean, range, and number of detections measured among the total number of samples for each sample type and radionuclide. From the data summaries, a radiological environ-mental monitoring report as specified in Regulatory Guide t.S (Ref.1) will be prepared and used as the basis for evaluating the radiation exposures re-sulting from the North Anna Power Station operations. The radiological environmental monitoring program (REMP) specifications are described in Appendix B to the Operating License (Ref. 7) and the required analyses and specifications are listed in Table 1. The overall objectives (Ref. 7) of the operational radiological environ-mental monitoring program are to identify changes of radioactivity in the vicinity of the North Anna Power Station and to provide information on the types and quantity of radiation in certain critical pathways and indicator organisms as a basis for evaluating radiation exposures to the population from the NAPS operations. O) \_ 1
TTEEC//flE ISOTOPES f-~ DESCRIPTION OF THE OPERATIONAL PnOs jd THE RADIOLOGICAL ENVIRONMENTAL PROGRAM The description of the operational radiological environmental ana-lysis program is presented in this section. Personnel of VEPCO collect the samples specified in Table 1 and ship them to Teledyne Isotopes for the analytical phase of the program. Interim data reports are submitted by Teledyne Isotopes as the analyses are completed, normally within 33 days of the date of receipt of samples (Ref. 9). Summary reports are issued quarterly by Teledyne Isotopes, usually within 45 days after the end of the quarter. The quarterly reports will be appended to this report and will contain (1) computer co=pilations of the analytical data from the interim data reports, (2) su=maries of the environmental radiological ana-lysis for each media listing the mean and range of detected radionuclides and the ratio of detected radionuclides to total measurements, (3) data interpretations for each media and analysis based on the summary table prepared in accordance with Regulatory Guide 4.3 (Ref.1). The radiological environments 1 program outlined in Table a contains the technical specification requirements for the North Anna Power Station (Ref. 7). Sampling station identifications and relative positions to the
's effluent release point are listed in Table 2 (Ref. 8) and shown on Figure 1 and Figure 2 (maps indicating the environmental sampling stations).
The operational environmental radiological program requires measurements on the following media. Airborne Particulates Particulate filters are collected weekly from air sampling stations 1, 2, 3, 4, 5, SA, 6, 7, 21, 22, 23, 24 and analy:ed for gross beta activity. Quarterly composites of these particulate air samples are analy:cd for Sr-89, Sr-90(second quarter only), and ga=ma emitting nuclides by high resolutien Ge(Li) gamma spectrometry. Air sampling stations are located on Ficures 1 and 2 and listed in Table 1. Lapse time recorders are used
's calculate actual air volumes.
Radiogas (Radioicdine) Charcoal cartridges are collected from sampling stations 1, 2, 3, 4, 5, SA, 6, 7, 21, 22, 23, 24 weekly. The cartridges are analy:ed for radioiodino by distillation and beta counting. Charcoal cartridge sampling locations are shown on Figures 1 and 2. o 2 s

Dosimeters are placed at each location and exchanges are made quarterly. TLDs are located at stations 1, 2, 3, 4, 5 SA, 6, 7, 21, 22, 23, 24 (See Table 1 and Figures 1 and 2). Station 24Isthecontrolstation. Milk Milk samples are collected monthly from locations 12,13,14A, and analy:ed for I-131 by chemical separation. Gamma isotopic emitters are analyzed by high resolution Ge(Li) gamma spectrometry. Quarterly milk samples are analyzed for Sr-89, Sr-90. Milk sampling locations are listed in Table I and shown in Figures 1 and 2. Well Water Water samples.are collected quarterly from the Environmental Laboratory Well 1A and analy:ed for tritium and for gamma emitting nuclides by high resolution Ge(Li) gamma spectrometry. The second quarter samples are also analy:cd for Sr-89, Sr-90. Surface Water A sample of surface water (North Anna River) is collected quarterly from Station 11 for tritium and gamma isotopic measurements. Surface - water sampics are also collected monthly from Station OS (Discharge) and Station 09(Reservoir) and analy:cd for tritium, iodine-131, and gamma isotopes. The second quarter surface water samples or composites are also analyzed for Sr-89, Sr-90. Fish Fish are collected annually near the beginning of the season from two locations and analy:ed for gamma emitting nuclides by high resolution Ge(Li) gamma spectrometry. Fish sampling sites are at locations 8 and 9 on Figure 1. Terrestrial Vegetation Samples of green leafy vegetation (cultivated or weeds) are collected annually during the harvest from two locations, Stations 21 and 23. These sampics are analy:ed for gamma emitting nuclides by high resolution Ge(Li) gamma spectrometry. , Soi! Soil sampics are co11ceted from lo' c. ions near the airborne stations every three years and analy:cd for gamma emitting nuclides by high resolution i V Ge(Li) gan=a spectrometry. The stations are 1, 3, 4, 5, 6, 7, 21, 22, 23, and 24. Stations 1, 21, 22, 23, and 24 are also analy:cd for Sr-89, Sr-90. 3

TTELEDYNE - ISOTOPES O ABSTRACTS OF Tile ANALYTICAL PROCEDURES The following are abstracts of the radionuclide separation, puri-ficztion, and measurement techniques used by Teledyne Isotopes. These tech-niques have been developed to meet the detection sensitivities (Table 3) and associated accuracies required by the nuclear industry in compliance with technical specifications. Air Particulates . Gross Beta Transfer filter to a 2-inch diameter planchet and assay in a Beck-man Sharp h'ide Beta II automatic alpha / beta counter. Gamma Isotopic Analysi_s Composite station filters are combined quarterly and radioassayed on a high resolution, high efficiency Ge(Li) detector. Radiogas Iodine-131 O Two procedures are used for the analysis of charcoal cartridges for iodine-131. METHOD 1. If the charcoal used is NOT impregnated with elemental iodine, iodide carrier is added and leached with NaOH. The stabic iodide and 1-131 is then stripped and extracted as iodine and precipitated as PdI.,, ' mounted on a nylon planchet, and assayed by low level beta. counting. METit0D 2. If the' charcoal used in the filters is impregnated with iodine, the chemical yield of the distillation procedure cannot be determined and the sampics are analy:cd by high resolution gamma spectrometry (Ge(Li)) by integration of the I-131 photopeak. Direct Radiation (TLD) CaSO 4
- Dy thermoluminescent dosimeter packets consisting of the four-area RadiGuard badge are placed at monitoring locations. At the end of the monitoring period, the dosimeters are returned to Teledyne Isotopes for readout. Results are reported in milliroentgen for the co11cetion period or mR/ collection time period.
l Milk, lodine-131 r Stabic iodide carrier is added to an aliquot of milk and the io-dide and-I-131 is removed by anion exchange resin. The iodine is stripped I O-11
W TELEM NE ISOTOPES with Na0C1 solution, reduced with hydroxylamine hydrochloride, and extracted into CIIC1 as free iodine (Is . I.t is then back-extracted into NallS0 solution and3 precipitated as Pdl),. The precipitate is mounted on a nylon3 planchet for low level beta counting. Strontium-89/ Strontium-90 To a liter of milk add strontium carrier and TCA solution. Stir solution and allow precipitation to settle overnight. Filter, wash, and dis-card precipitate. To the filtrate add oxalic acid, followed by Ni! 40H until the solution is alkaline in order to precipitate calcium and strontium oxalates. This precipitate is filtered and ashed, and the ash is dissolved in nitric acid. Strontium is purified by repeated precipitations as nitrate in concen-trated ilNO3 . Barium and iron scavenges are performed and stable yttrium carrier added , followed by a 5 to 7 day period for Y-90 ingrowth. The yttrium is precipitated as the hydroxide, redissolved and precipitated as the oxalate, and then mounted on a nylon planchet and counted in a low level beta counter. The strontium is precipitated from the sample as SrC03, mounted on a nylon planchet.and counted in a low level beta counter for Sr-89 and/or the Y-90 ingrowth. . Gamma Isotopic Analysis Transfc; liter of milk to a 1-liter wrap-around Marinelli count-ing beaker and radi, se,ay on a high resolution Ge(Li) detector. Well Water Tritium An aliquot of sample is converted to hydrogen gas by reduction in a hot zine furnace, mixed with methane counting gas and radioassayed utilizing an internal low level gas proportional counter. Very low levels of activity can be detected due to the sophistication of the counting equipment, the electronics, and the shielding. Gamma Isotopic Analysis One liter of sample is transferred to a 1-liter Marinelli wrap-around counting beaker and counted on a Ge(Li) detector. Surface Water Tritium An aliquot of sample is converted to hydrogen by gas reauction in a hot :ine furnace, mixed with methane counting gas and is radioassayed util-1:ing an internal low 1cvel gas proportional counter. Very low levels of ac-tivity can be detected due to the scphistication of the counting equipment, the cicctronics, and the shielding. 12

1 SPTELEDYNE ISOTOPES EXCEPTIONS AND SPECIAL EVENTS FIRST QUARTER 1981 JANUARY 1, 1981 - MARCH 31, 19S1 ,
-EXCEPTIONS During the first quarter of 1981 the schedule of analyses of samples from the vicinity of the North Anna Power Station (NAPS) was followed with ex-ception of the samples tabulated below:
COLLECTION PATHWAY SASTLE STATION PERIOD EXCEPTION Airborne AP, C 01 12/30-01/06 Equipment malfunction Airborne AP, C 05' 01/20-01/27 Equipment malfunction Airborne AP, C 05 01/27-02/03 Equipment malfunction Airborne AP, C 22 01/27-02/03 Equipment malfunction Airborne WP 01 01/01-01/31 low rainfall, no sample received .. V SPECIAL EVENTS The Peoples' Republic of China detonated an atmospheric, nuclear test on
~
October 16, 1980. The gross beta activities on weekly air pa.rticulate filters remained high in the first quarter of 1981 at a level of five times the level prior to October,'1930. The quarterly composites of the weekly air particulate filters still contain the fission products Zr-95, Ru-103,- Ce-141 and Cc-144 above the minimum levels of dttection. This is true of air particulate filters at several locations throughout the United States. 1 t O 4A
W TELEDYNE ISGTOPES (3 AIRBORNE EXPOSURE PATilWAY (JANUARY 1,1981 - FtARCli 31, 1981) AIR PARTICULATE FILTERS (STATIONS 1, 2, 3, 4, 5, SA, 6, 7, 21, 22, 23; 24) The gross beta activity in air particulate filters continued to increase during the first quarter of 1981 to a high of 0.19 pCi/Cu. bl. for the month of March 1931. The increase is attributed to the atmospheric, nuclear tests on October 19, 1980 by the Peoples' Republic of China and has continued at an increased level in many areas of the United States. The air filters are com-posited quarterly and measured on the gamma spectrometer. The fission pro-ducts Zr-95, Ru-103 and Ce-141 were monitored in twelve out of twelve measurements. These are relatively short-lived fission products which are also detected in other areat of the United States and are probably not due to the operations of the North Anna Power Station. The Ce-144 activity, which occurred in twelve of twelve measurements is 0.02 pCi/Cu. 51, which is slightly above the limit of detection but is probably due to the atmospheric nuclear tests. See Figure-3. AIR RADI0 IODINE (STATIONS 1, 2, 3, 4, 5, 5A, 7, 21, 22, 23, 24) No 1-131 was detected in the weekly charcoal cartridges collected in the /~} vicinity of NAPS. PRECIPITATION (STATION 01) Gross beta deposition in rainfall ranged from 1.2 - 6.2 nCi/sq. m. during February and Starch. There was insufficient rainfall in January for a gross beta measurement. This is a higher level of activity than in the past; therefore a sample was measured on a Ge(Li) spectrometer. >!easurements showed the presence cf Ir-95 and Ru-103. These nuclides'are also present in air particulate filters and are attributable to the Chinese atmospheric, nuclear test of October 16,19S0. SOIL (STATIONS 1, 2, 3, 4, 5, SA, 6, 7, 21, 22, 23, 24) No soil sampics were scheduled to be co!!ected during the first quarter of 1981. 5A

r% WATER ~ BORNE EXPOSURE PATHWAY (JANUARY 1, 1981 - MARCH 31, 1981) SURFACE WATER (STATIONS 08, 09) Camma emitting radionuclides and I-131 remained below the limits of detection at station 08 and 09. The level of tritium activity at station 08, the discharge lagoon, increased to 1900 pCi/ liter. Figure 5 illustrates the trend of tritium activity at station 08 from 1977 through the first quarter of 1981. The tritium activity at station 09 at Lake Anna, 2.2 miles upstream, 320 degrees remained at essentially the same level of 1200 pCi/ liter. RIVER tfATER (STATION 11) Tritium activity at station 11 increased to 2000 pCi/ liter during the first quarter of 1981 from 1570 pCi/ liter during the first quarter of 1980. No gamma emitters or I-131 were detected at station 11 suggesting that the effluent releases consist primarily of tritium. CROUND WATER (STATION 01A) Ground water from the environmental well contairmd no gamma emitters and the tritium activity (220 pCi/ liter) was at a nominal, environmental level. SEDIMENT / SILT (STATIONS 08, 09, 11) Sediment / silt samples were monitored for gamma .ctivities and contained , K-40, Ra-226 and Th-228, which are of terrestrial origin, at levels similar I to previous samplings. There were measurements of Cs-137 (3 of 3 measure-l ments) which is a fission product ar.d was also seen in airborne samples. I This suggests that fallout from previous and more recent nuclear, atmospheric testing was the source of this radionuclide. L SHORELINE SOIL (STATION 09) ( Shoreline soil showed the same results as sediment / silt samples. The same gamma emitters were present at a somewhat lower level of activity, o l l 15A

(-- Q,) CONCLUSIONS (JANUARY 1, - 1981 '- MARCH 31, 1981) The results of the radiological environmental monitoring program conducted in the environs of the North Anna Power Station show that no measurable releases from the nuclear plant, except tritium, were detected above the prescribed limits of detection. Increasing levels of tritium activity have been monitored The tritiumsince the activity start of operations in 1978 of unit 1 of the NAPS. at the discharge cooling (Station 08) is now 1900 pCi/ liter compared to 100-200 pCi/ liter during the preoperational period. In addition the tritium activity at Lake Anna, upstream 2.2 miles (Station 09) has increased from 160 pCi/ liter in the first quarter 1980 to 1200 pCi/ liter during the first quarter of 1981. The tritium activity in the North Anna River downstream 5.8 miles (Station 11) increased from 310 pCi/ liter in the first quarter 1980 to 2000 pCi/ liter during the first quarter of 1981. m

EXCEPTIONS AND SPECIAL EVENTS SECOND QUARTER 1981 MARCil 31, 1981 - JUNE 30, 1981 EXCEPTIONS During 'the second quarter of 1981 the sche'dule of analyses of samples from the vicinity of the North Anna Power Station (NAPS) was followed with ex-ception of the samples tabulated below: COLLECTION PATilWAY SAMPLE STATION PERIOD EXCEPTION Airborne AP,C 06 03/31-04/07 Equipment malfunction Airborne AP,C OSA 04/07-04/15 Timer malfunction no volume Airborne AP,C GSA 04/15-04/21 Timer malfunction no volume Airborne AP,C 05A 04/21-04/28 Equipment =alfunction (A)

- SPECIAL EVENTS The Peoples' Republic of China detonated an atmospheric, nuclear test on October 16, 19SO. The gross beta activities int weekly air particulate filters rose to a high of 0.3 pCi/Cu.M. in April of 1981. (See Figure 3) . Several gamma emitters such as Zr-95, Ru-103, Ru-106, Cs-137, Ce-141 and Ce-144 were detected in air particulate composites. Milk showed Cs-137 and Fish showed Cs-137 and Cs-134. Air particulate composites showed positive strontium 89 and 90. These detections were also noted in other areas throughout the United States and~are attributabic to the nuclear, atmospheric tests and are not due to the operations of the North Anna Power Station (NAPS).

T TELEDYNE ISOTOPES ( , s AIRBORNE EXPOSURE PATifdAY (MARCli 31, 1981 JUNE 30, 1981) AIR PARTICULATE FILTERS (STATIONS 1, 2, 3, 4, 5, 5A, 6, 7, 21, 22, 23, 24) The gross beta activity in air particulate filters continued to increase reaching a level of 0.30 pCi/Cu. M. for the month of April. In May the gross beta activity fell to 0.22 pCi/Cu. M. and . dropped still- further to 0.13 pCi/Cu.M. in June. The high level of gross beta activity is attributable to the atmospher-ic nuclear tests on October 16, 19S0 by the Peoples' Republic of China and has just begun to drop to a lower level in many areas of the United States. The air filters are composited quarterly and measured on the gamma spectrometer.
'Ihe second quarter composite is also analy:ed for strontium 89 and 90. The fission products Cr-95, Ru-103, Ru-106,Cs-137, Ce-141 and Cc-144 were found in most of the air particulate composites. These were at or slightly-higher than minimum detection levels. Mn-54 was found in two of the twelve composites.
These are attributsble to the nuclear tests of China and have been found in sample measurements in other areas of the United States. The Ce-141 activity (shown on Figure 3) was 0.004 pCi/Cu. M. which is higher than previously but is probably due'to the Chinese tests. The strontium 89 was positive in 11 of the 12 stations measured and averaged 0.013 pCi/Cu. M. The strontium 90 was-positive in 11 of the 12 stations measured and averaged 0.001 pCi/Cu. M. O This is comparabic to measurements in other areas of the United States and is V due to the atmospheric nuclear tests of October 1980. AIR RADI0 IODINE (STATIONS 1, 2, 3, 4, 5, SA, 6, 7, 21, 22, 23, 24) No I-131 was detected in the weekly charcoal cartridges collected in the vicinity of NAPS. PRECIPITATION (STATION 01) Gross beta deposition in rainfall ranged from 1.1-3.3 nCi/Sq. M. during the second quarter. This is a decline frcm the high in the first quarter. The semiannual composite was measured for tritium which was at a nominal, environ-mental level of 370 pCi/ liter. The analysis on the gamma spectrometer showed no gamma emitters present.. SOIL (STATIONS 1, 2, 3, 4, 5, SA, 6, 7, 21, 22, 23, 24) No soil samples are scheduled to be collected during 1981. Soil samples were collected in 19S0 and are not scheduled to be collected again until 19S3.

ENVIRONMENTAL GA>B!A DOSE - THERMOLLB!INESCENT DOSDfETERS (STATIONS 1, 2, 3, 4, 5, 5A, 6, 7, 21, 22,-23, 24) The average gamma environmental dose as measured cn1 thermoluminescent dosimeters in the vicinity of the North Anna Power Station during the second quarter of 1981 was 0.20 mR/ day. The range of-the environmental dose was 0.13 to 0.25 mR/ day. The highest doses were 0.25 mR/ day at station 6 and 0.24 mR/ day at station 23. The lowest dose was 0.13 mR/ day at. station'24, which is the control station, Orange at 22 miles 325 degrees. Figure 4 shows the plot of the average dose levels monitored, which indicates no change in the level of the direct exposure pathway due to the operation of the North Anna Power Station. See Table 5 in Appendix B which tabulates the exposure at each of the 12 stations monitored. O 4 l

'Q WATER BORNE EXPOSURE PATHWAY (APRIL 1, 1981 - JUNE 30, 1981) SURFACE WATER (STATIONS 08, 09) Gamma emitting radionuclides and I-131 remained below the limits of detection at stations 08 and 09. The level of tritium activity at station 08, the dishcarge lagoon, increased to 2500 pCi/ liter. Figure 5 illustrates the trend of tritium activity at station 08 from 1977 through the second quarter of 1981. The tritium activity at station 09 at Lake Anna, 2.2 miles upstream, 320 degrees increased to 1900 pCi/ liter. The second quarter composition of surface water was analyzed for strontium 89 and 90. These fission products were below the limits of detection indicating no adverse effects from the operation of NAPS. RIVER WATER (STATION 11) em Tritium activity at station 11 increased to 2400 pCi/ liter during the () second quarter of 1981 from 2000 pCi/ liter during the first quarter. No gamma emitters or I-131 were detected at station 11 suggesting that the effluent releases consist primarily of tritium. The second quarter sample'was analyzed for strontium 89 and 90. These were below the limits of detection. GROUND WATER (STATION 01A) Ground water from the environmental well contained no gamma emitters and the tritium activity (220 pCi/ liter) was at a nominal, environmental level. No strontium 89 or 90 was detected in the second quarter composite indicating no adverse effects due to the operation of NAPS. ISB

MILK (STATIONS 12, 13, 14A) Milk samples collected from the three stations contained the usual radio-nuclides, K-40 and Sr-90.- The average Sr-90 activity was 3.4 pCi/ liter com-pared to 3.2 pCi/ liter for the fourth quarter of 1930. See Figure 6 for the
- quarterly level of Sr-90 activity since 1977.
Iodine-131 was below the limits of detection of 0.5 pri/ liter. These results indicate that no detectable NAPS releases occurred that adversely affected milk samples. FISII (STATIONS 08,09) Fish samples from stations 03 and 09 were analyzed on the Ge(Li) -spectrometer. They contained the usual level of K-40. In addition there was one. detection of-Cs-134 below the minimum icvel of detection and two detections of Cs-137. .These are fission products detected also in air particulates and attributable to the Chinese nuclear tests in October 1980. TERRESTRI AL VEGETATION (STATION 23) A sample of green leafy vegetables collected in the environs of NAPS contain-ed the usual nuclides _ Be-7 and K-40. All other gamma emitters were below the f limits of detection indicating that no detectable SAPS related gamma emitters occurred, s i l i O l- - 20B t -- - * " - -v--r-+ - - - - , - - - - - - --

( (, b' CONCLUSIONS (APRIL 1, 1981 - JUNE 30, 1981) The results of the radiological environmental monitoring program conducted in the environs of the North Anna Power Station show that no measurable releases from the nuclear plant, except tritium, were detected above the pre-scribed limits of detection. Increasing levels of tritium activity have been monitored since the start of operations in 1978 of unit 1 of NAPS. The tritium activity at the discharge cooling (Station 08) is nov 2500 pCi/ liter compared to 100-200 pCi/ liter during the preoperational period. In addition the tritium activity at Lake Anna, upstream 2.2 miles (Station
- 09) has increased from 160 pCi/ liter in the first quarter 1980 to 1900 pCi/ liter during the second quarter of 1981.
The tritium activity in the North Anna River downstream 5.8 miles (Station 11) increased from 310 pci/ liter in the first quarter 1980 to 2400 pCi/ liter during JI the first quarter of 1981. [) v \ l l . 25B t . .
