TTELEDYNE : ISOTOPES * ( INTRODUCTION Outlined in this document is the description of the operational environmental radiological monitoring program conducted by Virginia Electric and Power Company for the North Anna Power Station, and a compilation of the data generated to satisfy the monitoring requirements. This program is based on the technical specifications requiring the collection and analysis of var-ious sample media to provide information on the type and quantity of radio-activity in certain indicator organisms or critical pathways. The operational program became mandatory on April 5,1978 upon granting of the operating li-cense for the North Anna Power Station Unit 1. Virginia Electric and Power Company is responsible for the col-1ection of the samples required for the program and Teledyne Isotopes is respoasibic for the analysis of each sampic and submission of the reports of analysis. Quarterly summaries of the data reported for each sample type will be appended to this document for the period of January 1,1978 through December 31, 1978. These quarterly data summaries will include a compilation of the radioactivities reported for each sample type and pathway and a summary of the mean, range, and detections / total for each sample type and'radionuclide. From the data summaries, a radiological environmental monitoring program ( summary table as specified 'in Regulatory Guide 4.8 (Ref.1) will be prepared and used as the basis for evaluating the radiation exposures resulting from the North Anna Power Station operations. Baseline levels of radioactivity in the environs of the North Anna Power Station have been established during the preoperational phase conducted from' July 1,1974 through December 31, 1977 (Ref. 2-6) . On April 5,1978 the operating license for the North Anna Power Station - Unit 1 was granted requiring the transi' tion from the preoperational to the operational phase of the radiological environmental monitoring program. The operational phase of the program is described in Appendix B to the Operating License (Ref. 7) and the required analysis and specifica-tions (Table 1) were phased into the program during the January 1 - Flarch 31, 1978 quarter. The overall objectives (Ref. 7) of the operational radiological envirunmental 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 quaatity of radiation in certain critical pathways and indicator organisms as a basis for evaluating radiation exposure from sta-tion operation. 1
TTELEDYNE . ISOTOPES DESCRIPTION OF Tile OPERATIONAL PROGRAM { THE RADIOLOGICAL ENVIRODfENTAL PROGRMI The .lescription 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 Tcledyne Isotopes for the analytical phase of the progran. 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 compilations of the axialytical data: from the interim data reports, (2) summaries of the environmental radi.ological 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 4.8 (Ref.1). The radiological environmental program outlined in Table 1 con-tains the technical specification requirements for the North Anna Power Station (Ref. 7 ). Sampling station identifications and relative positions to the effluent releasc 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, 3, 5, 7, 21, 22, 23, 24 and analyzed for gross beta activity, Quarterly composites of these particulate air samples are analy::ed for Sr-89, Sr-90 (second quarter'only), and gammacemit-tbg nuclides by high resolution Ge(Li) gamma spectrometry. Air sampling stations are located on Figures I and 2 and listed in Table 1. Lapse time recorders are usedtto calculate actual air volumes. Radiogas (Radioiodine) Charcoal cartridges are collected from sampling stations 3, 21, 23, 24 weekly. The cartridges are analyzed for radioiodine by distillation and beta counting. Charcoal cartridge sampling locations are shown on Figures 1 and 2. ( 2

TTELEDYNE ISOTOPES ( Direct Radiation Environmental direct radiation levels are monitored by thern-oluminescent dosimeters (TLD) using a multi-arca, phosphor teflon CaSO 4
- Dy dosimeter. Dosimeters are placed at each location and ex-changes are made quarterly. TLDs are located at stations 1, 3, 4, S, 6, 7, 21, 22, 23, and 24 (see Table 1 and Figures 1 and 2) .
Milk Milk somples are collected monthly from locations'I2, 13, 14 and analyzed for I-131 by chemical separation and gamma isotopic emit-ters by high resolution Ge(Li) gamma spectrcmetry. Quarterly milk sampics are analyzed for Sr-89, Sr-90. Milk sampling locations are listed in Table 1 and shown in Figures 1 and 2. Well Water Water samples are co11ceted quarterly from the Environmental Laboratory well and analy:cd for tritium and for gamma emitting nu-clides by high resolution Ge(Li) gamma spectrometry. The second quarter samples are also analyzed for Sr-89, Sr-90. Surface Water ( A sample of surf ace water (North Anna River) is collected quar-terly from Station 11 for tritium and gamma isotopic nuclides. Surface water samples are also collected monthly from Station 08 (Discharge)
' and Station 09 (Reservoir) and analyzed for tritium, iodine-131, and gamma isotopes. The second quarter surface water sampics or composites are also analyzed for Sr-89, Sr-90.
Fish Fish are co11ceteo annually near the beginning of the season from two locations and analyzed for ganma 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 Icafy vegetation (cultivated or weeds) are collected annually during the harvest frnm two locations, Stations 21 and 23. These samples are analy:cd for gamma emitting nuclides by high resolution Ge(Li) gamma spectrometry. S. i l. Soil samples are collected from locations near the airborne stations every three years and analy:cd for gamma emitting nuclides f by high resolution Ge(L1) gamma 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 Sediment / Silt ( Silt sampics from Stations 8, 9, and 11 along with a shore-line sample from the vicinity of Station 9 are collected semiannually and analyzed for gamma emitting nuclides by high resolution Ge(Li) gamma spectrometry. Sediment / silt samples are analyzed annually for Sr-89, Sr-90. ( ( 4

( ABSTRACTS OF THE ANA1XTICAL PROCEDURES The following are abstracts of the radionuclide separation, puri-fication, and measurement techniques used by Teledyne Isotopes. These tech-niques have been developed to meet the detection sensitivities (Tabic 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 Analysis . Composite station filters are combined quarterly and radioassayed on a high resolution, high efficiency Ge(Li) detector. Radiogas Iodine-131 k Two precedures are used for the analysis of charcoal cartridges for iodine-131. FETHOD 1., If the charcoal used is NOT impregnated with elemental iodine, iodide carrier is added and leached with NaOH. The stabic iodide and I-131 is then stripped and extracted as iodine and precipitated as PdI 2' mounted on a nylon planchet, and assayed bf low level tet.. counting. FETHOD 2. If the charcoal used in the filters is impregnated with iodine, the chemical yield of the distillation procedure cannot be determined and the samples are analyzed by high resolution gamma spectrometry (Ge(Li)) by integration of the I-131 photopeak. Direct Radiation (TLD) CaSO4
- 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 mR for the collection period or mR/ collection time period.

It is then back extracted into 3 NallS03 solution and precipitated as PdI 2 . The precipitate is mounted on a nylon planchet for low level beta counting. Strontium-89/ Strontium-90 To 1 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 and oxalic acid, followed by NH 4 0H 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. Fe(OH)3 scavenges are performed and stable yttrium carrier added, followed by a 5 to 7 day period for Y-90 ingrowth. The yttrium is precipi-tated 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 SrCO , mounted on a nylon planchet and counted in a low level beta counter for kr-89 and/or the Y-90 ingrowth. Gamma Isotopic Analysis Transfer 1 liter of milk to a 1-11ter wrap-around Marinelli ceunt-ing beaker and radioassay on a high resolution Ge(Li) detector. Well Water Tritium An aliquot of sample is converted to hydrogen gas by reduction in a hot zinc 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 reduction in a hot zine furnace, mixed with methane counting gas and is radioassayed util-izing an internal low level gas proportional counter.

Gross Beta Evaporated or solid phase aliquots are transferred to a 2-inch diameter stainless steel planchet and counted in a low level gas flow thin window Geiger counter. Ge(Li) Gamma Spectrometry Based upon the specific media to be analyzed, samples are counted in 1-liter wrap-around Marinelli type containers, 300 m1 bottles or 2-inch filter paper source geometries on 55 cc Ge(Li) detectors coupled to multi-channel spectrometers. AlI resultant spectra are maintained on magnetic tape for computer analysis and for future reference. Strontium-89/ Strontium-90 After decomposition and radiochemical separation and purfication, mounts of Sr-89 and Y-90 are counted in a low level gas flow thin window Geiger counter. Nuclide purity is established by counting over at least one half-life for Y-90 and by multiple counts for Sr-89. ( Tritium

SUMMARY
OF QUARTERLY RESULTS AND DISCUSSION , . EXCEPTIONS AND SPECIAL EVENTS (JANUARY 1, 1978 - MARCII 31, 1978) EXCEPTIONS The operational program for the North Anna Power Station requires the weekly analysis of I-131 in charcoal filters with air volumes of approx-imately 125 cubic neters and sensitivities of less than 0.024 pCi/Cu. M. (see Table 1 in the Description of the Program) . During the preoperational program most of the charcoal filters were impregnated with elemental iodine necessitating the analysis for I-131 by high resolution gamma spectrometry. By this procedure the limits of detection were lower than the 0.025 pCi/Cu. M. However, the collection periods and the volumes were at least 10 times longer. In addition, the activities were calculated to the end of the collection time. For the operational program, 125 cubic meters of air and calculation to mid-co11cetion were specified to insure against exceeding the sensitivity of 0.025 pCi/Cu. M. This requires the chemical separation of iodine and low level beta counting of the sample --a procedure possibic only with noniodine im-pregnated charcoal. By using nonimpregnated charcoal and processing by chemical separation, the limits of detection are lower than 0.01 pCi/Cu. M. for 125 cubic meters of air and calculation to mid-collection time and counting within S days after collection. It is recommended that nonimpregnated with elemental iodine charcoal cartridges be used and chemical separation be employed to insure compliance with the L.T. 0.025 pCi/Cu. M. specification. SPECIAL EVENTS On March 14, 1978 the Peoples Republic of China detonated an atmospheric nuclear device at the Lop Nor atomic test site. The reported yield of this nuclear device was approximately 10 kilotons. The operational program for the site was implemented in anticipation of initial criticality of Unit i. 19-A
TTELEDYNE - ISOTOPES . SUFMARY OF QUARTERLY RESULTS AND DISCUSSION EXCEPTIONS AND SPECIA: EVENTS (APRIL 1,1978 - JUNE 30,1978) EXCEPTIONS The use of stable iodine impregnated charcoal filters continued during the second quarter of 1978 necessitating radioassay by high resolu-tion gamma spectrometry for I-131. The lower sensitivity gamma spectrometry precludes its use and requires the higher sensitivity of chemical separation of iodine and the use of non-impregnated charcoal filters. Non-impregnated charcoal filters are on order by Vepco and will be used when received. SPECIAL EVENTS On April 5,1978 the operating license for the North Anna Power Station Unit I was granted and the operating phase of the radiological en-vironmental monitoring program is in effect. 19-B

( SU5 MARY PF QUARTERLY RESULTS AND DISCUSSION EXCEPTIONS AND SPECIAL EVENTS (JULY 1,1978-SEPTEMBER 30, 1978) EXCEPTIONS Charcoal filters not impregnated with stabic iodine were phased into the NAPS operations beginning August 1, 1978. The use of these charcoal filters pernits the analysis for I-131 by the more sensitive radiochemical analytical procedure and the linits of detection are lower than the specification of L.T. 0.02S pCi/Cu.ft. SPECIAL EVENTS No unusual events occurred during the third quarter of 1978 that could be interpreted as possibly related to the operations of the North Anna Power Station. The last atmospheric nuclear test in the northern hemisphere was conducted on March 14, 1978 by the Peoples Republic of China. Most of the short lived and early fallout in North Anna already was detected prior to this 3rd quarter of 1978. k > 19-C

( AIRBORNE EXPOSURE PA'lW AY (JANUARY 1,1978 - MARCil 31, 1978) AIR PARTICULATE Filters were collected weekly from stations 01, 03, 05, 07, 21, 22, 23 and 24 and analyzed as required in Table 1. In addition, sampics from stations 02, 04 and 06 were collected and analyzed even though not required in the radiological monitoring program (Ref. 7) Summarized in Tabic 4 are the radionuclides detected on the air parti-culate filters. Gross beta and Cc-144 activities are plotted on Figure 3. The gross beta activity increased sharply during the week of 03/21-03/28, the result of the atmospheric nuclear detonation on March 14, 1978 by the Peoples Republic of China. Gamma analysis of the quarterly composite of the air particulate filters from each station showed Zr-95, Ru-103, Cs-137, Cc-141 and Cc-144 at levels slightly higher than during the fourth quarter of 1977. The small in-crease of Cc-144 is shown on Figure 3. The radionuclides detected as air parti-culates are fission products attributed to fallout from the Chinese atmospheric nuclear tests during 1976, 1977 and on March 14, 1978. AIR RADI0 IODINE ( , Charcoal filters were co11ceted from stations 03, 21, 23 and 24 as specified in Table 1. In addition charcoal filters were collected at stations 01, 02, 04, 05, 06, 07 and 22 providing additional analysis not required by the ERMP. As discussed under " Exceptions", the limits of detection for I-131 ex-ceeded the MDL of 0.025 pCi/Cu. M. because of the use of elemental iodine impregnated charcoal. Recommendations have been made to correct this deficiency. Iodine-131 was detected in nine of the eleven charcoal filters exposed during the week of 03/21-03/28 at a mean level of 0.07 pCi/Cu. M. See the summary tabic.for I-131 in charcoal filters in Appendix "A" for the compilation of data and see Tabic 4 in this section for an overall summary and comparison. SOIL Sampics were not scheduled for analyses during this quarter. Analyses of soil sampics are required' once every three years at stations 01, 03, 04, 05, 06, 07, 21, 22, 23 and 24. These stations are also co11cetion sites for air particulate sampics with the exception of stations 04 and 06. PRECIPITATION Sample analysis are not required as a part of the environmental monitoring program for the North Anna Power Station environs. The analysis of precipitation samples for gross beta activity at Station 01 are additional ( analysis and provide information useful for interpreting pathways for airborne exposures to radionuclides. 20-A
"RTELEDYNE - ISOTOPES SU.4!ARY OF QUARTERLY RESULTS AND DISCUSSION ( AIRBORNE EXPOSURE PATHh'AY (APRIL 1,1978 - JUNE 30,1978) AIR PARTICULATE Filters were co11ceted weekly from Stations 01 through 07 and 21 through 24 and analyzed as specified in Table 1. Summarized in Table 4 are the radionuclides detected on the air particulate filters (quarterly averages). Gross beta activity and the shorter-lived gamma isotopes (Ru-103, Zr-95, I-131) decreased from the levels monitored during the first quarter. The longer-lived radionuclides (Cs-137 and Cc-144) from the Chinese atmospheric nuclear tests 'of 1977 and March 14, 1978 were - monitored at higher levels compared to the first quarter measurements. Plotted on Figure 3 are the gross beta activities and the Cc-144 activity monitored on air particulate filters. AIR RADI0 IODINE Charcoal filters were collected weekly from Stations 01 through 07 and 21 through 24 and analyzed for I-131. No I-131 was detected during the second quarter of 1978 compared to nine positive readings during the first quarter (see Table 4). ( PRECIPITATION Rainfall samples were collected from Station 01 (Onsite) and are measured for inches of rainfall and then monitored for gross beta and tritium. The deposition of gross beta emitting was 1.4 nCi/sq.m. during the second quarter compared to 2.2 nCi/sq.m. during the first quarter. J 20-B
TTELEDYNE ISOTOPES ( SUE!ARY OF QUARTERLY RESULTS AND DISCUSSION AIRBORNE EXPOSURE PATilNAY (JULY 1,1978-SEPTEJfBER 30, 1978) AIR PARTICULATE Summari:cd in Tabic 4 are the radionuclides detected on the air particulate filters. During this third quarter 1978 the gross beta activity decreased progressively from July through September (See . Figure 3) . Ce-144 also decreased to 0.0089 pCi/Cu.M. ,' the lokest quarterly activity for 1978. From these results the airborne exposure at NAPS was nominal during the 3rd quarter of 1978. AIR RADI0 IODINE No detections of I-131 were monitored during the 3rd quarter of 1978 at NAPS. Starting August 1, the non-impregnated stable iodine cartridges were used permitting analysis by radiochemical procedures and resulting in a lower limit of detection of L.T. 0.024 pCi/Cu.M. Since this date we are confident no sources of I-131 higher than the LLD were detected. k PRECIPITATION Rainfall sample were collected during the 3rd quarter. The gross beta activity is consistent with activities during the 1st and 2nd quarters. s 9 ( 20-C
'PTELEDYNE , ISOTOPES SUSB!ARY OF QUARTERLY RESULTS AND DISCUSSION ( AIRBORNE EXPOSilRE PATIIWAY (OLTOBER 1,1978 - DECEMBER 31, 1978) AIR PARTICULATE The gross beta particulate activity of air sampics flowing through paper filters remained at low 1cycls compared to the activities monitored in the previous quarters of 1978 and in 1977. In addition the gamma activities of fission products and of Cc-144 in particular were below the limits of detection. See Figure 3 for plots of the gross beta and the Ce-144 activities during 1977 and 1978. Summarized in the REMPS table 4 are the data compilation of the nuclides monitored for the operational program at the North Anna Nuclear Power Station (NAPS) . The data in Table 4 is for each of the four qua:ters of 1978. AIR RADI0 IODINE No detections of I-131 in air samples flowing through charcoal filters were monitored during this quarter. The pattern of no detectabic radiodine both at close in to NAPS sites and at distant collection stations justifies the conclusion that the airborne releases from NAPS are negligible and are below the detection limits specified in the NAPS operating specifications. PRECIPITATIO_N ( Rainfall samples collected during this quarter also contained low levels of beta activity per liter of sample. These values are less than half of the activity monitored in rainfall during the previous three quarters (see Table 4) . SOIL No soil sampics were analyzed during 1978. The schedule requires analysis of soi samples once every three years. ( 20-D

The average gamma dose during the second quarter is 0.30 mR/ day and is sum-marized in Table 5 and plotted on Figure 4. The aver. age gamma dose for the nine month period 09/20/77-06/27/78 is 0.25 mR/ day. The average of the fourth quarter 1977 and the first and second quarter of 1978 gamma dose is 0.22 mR/ day compared to the corresponding 0.25 nR/ day for the nine month period. The high environmental dose during the second quarter 1978 could result from washdown and ground deposition of fission radionuclides from the March 14, 1978 atmospheric nuclear test by the Peopics Republic of China, k .

These three samples were analyzed as outlined in Table 1 and the results are summarized in Tabic 6. Presented on Figure 5 is the tritium activity from station 08, the discharge cooling water. The tritium activ_ity of 110 pCi/ liter is consistent.with preoperational measurements (see References 2 through 6). GROUND WATER Ground water (well water) samples were collected at station IA, the Environmental Laboratory Well and analyzed for tritium and gamma. emitting nuclides. All activities in ground water were below the limits of detection and t_he results are summarized in Table 6. AQUATIC SEDIMENT AND SHORELINE SOIL Samples were collected from station 08, near the discharge cooling water for the NAPS, from station 09 at the reservoir and from station 11, the North Anna River. In addition, a soil sample was collected in the vicinity of ( station 09, the reservoir. Sediment and shoreline soils were analyzed for gamma emitting radio-nuclides and the results are tabulated in Appendix "A" and siamarized in Tabic 6. Usual gamma emitting radionuclides in sediments ate K-40, Cs-137, Ra-226 and Th-228, and the levels of activity are of the san e magnitude as monitored during the preoperational program. ( 31-A

TTELEDYNE . ISOTOPES SUSB!ARY OF QUARTERLY RESULTS AND DISCUSSION I WATERBORNE EXPOSURE PATHWAY (JULY 1,1978-SEPTEMBER 30, 1978) SURFACE WATER Samples collected from stations 03,09, and 11 were analyzed for I-131, H-3 and gamma isotopes. The H-3 level at Station 08, the Surface Water discharge cooling, increased to 700 pCi/ liter the highest activity monitored at this locatior (see Figure 5). At Station 11, the North Anna River Station, the H-3 activity wa,s 870 pCi/ liter and at Station 09, the Reservoir Station, the H-3 activity.was 420 pei/ liter, These H-3 activities are greater than monitored for the previous quarters of !978 and could be the result of releases, subject to verification, from the NAPS. No I-131 or gamma emitting nuclides were detected in surface water samples inferring that possible releases from NAPS were nominal and non-detectable. GROUND WATER Samples collected at the Environmental Well (Station I A) contains no radioactivities of H-3 or gamma emitters above the limits of detection. The results are summarized in Table 6. ( AQUATIC SEDIMENT AND SHORELINE SOIL The aquatic sediment sampics .an'1 shoreline sampics from the vicinity of station 09 were monitored for gamma emitting radionuclides and Sr-89,Sr-90. Only radionuclides characteristic of sediment and soil were detected and the activity levels- were in the same order of . magnitude as observed in previous years.

Plotted in Figure S is the tritium activity at station 08, surface water discharge cooling. The activity of tritium at this station remains at 760 pCi/ liter, the trend observed in the previous quarter. Tabulated in the REMPS Tabic 6 are the summaries of detected radioactivities activities monitored during each quarter of 1978. The increase of radioactivity due to operations of the NAPS is detected for tritium and is plotted in Figure 5 for station 08. In addition the tritium level at the reservoir (Station 09) is also higher at 600 pCi/ liter compared to 380 and 420 pCi/ liter monitored in the 2nd and 3rd quarters. The tritium activity at Station 11, North Anna River is 890 pCi/ liter compared to 870 pCi/ liters monitored in the 3rd quarter. No changes in the gamma isotopic, iodine-131 or Sr-89 activities were monitored during,
. 1978 indicating no detectabic releases of these radionuclides from NAPS by the
( waterborne pathway. GROUND WATER Ground water samples from Station 1A, the Envrionmental Well, contain no detectable levels of monitored radionuclides that could be attributed to operations of NAPS. In fact the radioactivitics of ground water sampics remain below the limits of detection for tritium, gamma isotopes, and for Sr-89, Sr-90. ( 31-D

SUMMARY
OF QUARTERLY RESULTS AND DISCUSSION INGESTION EXPOSURE PATIINAY (JANUARY 1,1978 - MARCil 31, 1978 MILK Samples were collected from stations 12, 1.3 and 14 and monitored for low levels of I-131 ( 0.5 pCi/ liter) for gamma emitting radionuclides, and for Sr-89, Sr-90. The IcVels of activity of detected radionuclides are tabulated in Appendix "A" and summari cd in Table 7. Presented on Figure 6 is the Sr-90 activity in milk at levels consistent with preoperational values. FISil Sampics were not scheduled for analysis during this quarter. Analysis is required annually at the beginning of the season for gamma isotopes. GREEN LEAFY VEGETATION Samples were not schedul?d for analysis during this quarter. The specifications require analysis annually during harvest. ( ( 38-A
"PCTELEDYNE ISOTOPES SU> NARY OF QUARTERLY RESULTS AND DISCUSSION
( INGESTION EXPOSURE PATillfAY (APRIL 1,1978 - JUNE 30,1978) MILK Milk samples are collected from Stations 12,13, and 14 and moni-tored for low levels of I-131 (0.5 pCi/ liter) for gmama isotopes and for Sr-89/Sr-90. Summarized in Tabic 7 are the average activities required under the program summary. No changes in the levels of activity were moni-tored during the second quarter of 1978 compared to the first quarter of 1978. FISit Fish sampics are analyzed annually for gamma isotopes at the beginning of the fishing season on sampics from Stations 09 and 10. A single detection of Cs-137 at 0.05 pCi/gm wet was made on one fish sample. No other gamma emitters were monitored in fish samples from the North Anna Power Station environs. ( ( 38-B
T TELEDYNE ISOTOPES SU) MARY OF QUARTERLY RESULTS AND DISCUSSION ( INGESTION EXPOSURE PATilh'AY (JULY 1,1978-SEPTEMBER 30, 1978) MILK Milk sampics collected from stations 12, 13, and 14 were monitored for low levels of I-131, Sr-89,Sr-90 and gamma emitting radionuclides. No I 131 was detected, consistent with no detections of I-131 in other pathways. Sr-89 was below the limits of detection indicating no recent releases of fission products to the environs. Sr-90 monitored at an average of 4.4 pei/ liter compares favorably with measurements during 1977 and the previous quarters cf 1978. Both K-40 and Cs-137 in milk during this quarter are the same as the results monitored during the first two quarters of 1978. In summary, no radio-nuclides in milk (ingestion pathway) were affected by any possible releases from NAPS. FISil No analysis were scheduled during the third quarter for fish samples. (- (

Plotted on Figure 6 is the quarterly average of Sr-90 in nilk. The average Sr-90 activity is 2.2 pei/ liter, a level lower than nonitored during previous quarters of 1977 or 1978. Summarized in Tabic 7 are the analysis performed for radionuclides in milk. No changes were measured in activities of the nonitored radionuclides indicating no detectable levels of radionuclides from NAPS in milk sampics. FISil No analysis were scheduled during this quarter.

TTELEDYNE ISOTOPES CONCLUSIONS (January 1,1978-March 31,1978) For the first quarter (January 1 - March 31,1978) the analysis per-formed to satisfy the provisions of the Environmental Radiological Monitoring Program (ERNP) in the vicinity of the Nortn Anna Power Station (NAPS) are pre-sented in this report. The activity levels of the detected radionuclides remained witnin ranges measured during the preoperational program (see Ref. 6). Thus, the radioactivities measured during this first quarter are the baseline environmental IcVels anc no radionuclides were measured that could by generated by the NAPS. Possible sources of environmental radioactivity and exposure at NAPS are: (1) environmental natural activity, (2) releases from the nuclear power station, (3) worldwide fallout from atmospheric nuclear devices, and (4) ex-posures and released from. medical and industr.ial sources. The ERMP at NAPS is structured to permit evaluation of and assignment to each of these sources of any measured dose or radioactivity. Thus, the detection of iodine-131 during the week of 03/21/73 - 03/28/78 was assigned to worldwide fallout from the Fhrch 14, 1978 atmospheric nuclear detonation by the Peoples Republic of China at Lop Nor, Central Asia. The uniform and widespread distribution of the iodine-131 in nine of the ten operating collection stations supports this conclusion. In addition, iodine-131 fallout was reported by most investigators :hroughout the United States during this period. During this quarter iodine-131 was detected in the airborne exposure pathway (charcoal filters) and not in the waterborne or ingestion pathways. If detected IcVels of radioactivity were measured in water or milk, the dose to the maximum exposed individual (infants) can be calculated from Regulatory Guide 1.109 (Ref. 12). , Thus the correlation of radioactivity with dose level is available in the literature in compilations such as the EPA - Radiological Quality of the Environment in the United States (Ref.11) . Dose levels from natural and arti-ficial sources are listed in Table 8 and taken from Ref. 11. The average ambient external gamma dose in Virginia is listed as 55 mrem / year in Table S. The ambient external gamma dose measured in the environs of NAPS was 0.18 (365) = 66 mr/ year. 42-A
TTELEDYNE LSOTOPES CONCLUSIONS (April 1,1978-June 30,1978) Presented in this report are the analyses performed during the second quarter (April 1 - June 30,1978) to satisfy the provisions of the Environmental Radiological Monitoring Program (ERMP) in the vicinity of the North Anna Power Station (NAPS) . Comparing the data for this quarter with that from the preoperational program justifies the conclusion that the IcVels of radioactivities have remained the same. No radionuclides were n:asured that could be attributed to operations of NAPS. All radio-nuclides detected in the environs of NAPS are at the baseline environmental levels and duplicate results obtained for the preoperational program. Also detected were fission products from the atmospher.ic nucicar tests by the Peoples Republic of China in 1977 and on March 14, 1978 and detec-ted in the atmospheric pathway. Possible sources of environmental radioactivity and exposure of the population are (1) environmental natural radioactivity, (2) releases from nuclear power stations, (3) worldwide fallout from atmospheric nuclear
-evices, and (4) exposures and releases from medical and/or industrial sources. The ERMP at NAPS is structured to permit evaluation and assign:.ent to these sources of measured doses or radioactivities. Average radiation doses to the individual from natural and artificial sources are listed in Table 8.

TTELEDYNE ISOTOPES CONCLUSIONS ( (JULY 1,1978-SEPTEMBER 30,1978) Appended to this report are the analyses performed during the third quarter of 1978 for the Environmental Radiological Monitoring Program in the environs of the North Anna Power Station of the Virginia Electric and Power Company. The results generated during this quarter show no measurabic effect from operations of the power station, with the possibic exception of increased H-3 1cvels in surface water at the Discharge Lanoons (Station 08), Lake Anna, Upstream (Station 09) and North Anna River, downstream (Station 11). However to verify the source and pathuay of the distribution of the H-3, additional measurements must be generated for future monitoring periods. The possibic sources of natural and 2rtificial environmental radioactivity have been reviewed previously and are listed in Table 8. ( ( 42-C
'FrTELEDYNE ' ISOTOPES CONCLUSIONS (October 1, 1978 - December 31, 1978) ( The results of the Radiological Environmental Monitoring Program conducted at the North Anna Power Station of the Virginia Electric and Power Company in-dicate no detectable levels of nuclear plant related radionuclides other than tritium in the environs. The tritium levels at the three surface water stations (08,09, and 11) have increased during 1978 and the maximum H-3 Icvel was 890 pCi/ liter at Station 11 (North Anna River) during the third quarter of 1978. The maximum H-3 level at the Reservoir (Station 09) was .600 p'Ci/ liter and the dose implications to the maximum exposed individual (assume a child) from ingestion of reservoir water can be calculated from Reg. Guide 1.109 (Ref 12) . From Reg. Guide 1.109 the ingestion dose factor for a child is 2.03 E-07 mrem /pCi ingested and the annual ingestion of water is 510 liters / year, thus the ingestion dose to a child is 0.062 mrem / year. A total body dose of 0.062 nrem/ year is neglibic compared to the K-40 internal constituent of the body of 17 mrem / year (see Table 8) . Thus we conclude that the detectable measurement of 600 pCi/ liter of tritium in drinking water poses no radiation dose implication to man based on the dose factors compiled in Reg. Guide 1.109. [ An atmospheric nuclear test was conducted by the Peoples Republic of China on December 13, 1978. No early fallout from this test was detected in airborne samples collected through the end of the quarter on December 31, 1978. ( 42-D

The dosimeters were annealed at the North Anne Power Station of the Virginia Electric and Power Company prior to exposure in the field thus cancelling an in-transit dose. After exposure and collection of the field dosimeters and prior to shipment to Teledyne Isotopes, the control dosimeters only were annealed and shipped with the field dosimeters to T1 providing a measure of the return in-transit dose. The net mR/ day ir the gross mR/ day of the Geld dosimeters minus the return in-transit dose of the control dosimeters.
