SUMMARY
o During this operating period for Calvert Cliffs Nuclear Power Plant Units 1 and 2, Teledyne Isotopes and Baltimore Gas and Electric Company (BG&E) i analyzed samples from the aquatic, atmospheric, and terrestrial environments. A total of 1,889 analyses were performed on 742 environmental samples during this period. In addition, BG&E personnel analyzed 629 thermoluminescent dosimeters (TLD's) for ambient radiation dose rates.
1 Samples from the aquatic environment included bay water, fish, shellfish (oysters and crabs), and sediment. Bay water was analyzed for tritium, Sr-89, Sr-98, and gamma emitting nuclides. Fish, shellfish, and sediment were analyzed for gamma emitting nuclides. Fish bones and sediment were also analyzed for Sr-89 and Sr-98.
Monitoring of the atmospheric environment included sampling air and precipitation. Air particulates and gaseous iodine were collected on glass fiber filters and silver zeolite molecular sieve cartridges, respectively.
The particulate filters were analyzed tor gross beta activity and for gamma emitting nuclides, while the molecular sieve cartridges were analyzed for I-131. Analyses were made for Sr-89 and Sr-98 on quarterly composited air particulate filters. Precipitation was analyzed for gross
'
- beta, H-3, Sr-89, Sr-99, and gamma emitting nuclides.
Samples from the terrestrial environment included milk, vegetation, soil,
- and ground water samples. Milk samples were analyzed for gamma emitters, I-131, Sr-89, and Sr-98. The vegetation and soil samples were analyzed i I
for gamma emitters, Sr-89, and Sr-90. The ground water samples were analyzed for H-3 and gamma emitters.
Measurements of external radiation were performed by analyzing TLD's from 13 locations surrounding the plant.
Low levels of various radionuclides were observed in the environs of the plant during 1983. Some of these observations are attributable to fallout from past atmospheric nuclear testing, and some are related to the operation of the plant. With reference to the latter observations: H-3 was observed in a few bay water samples from location 7; Ag-118m was observed in a few crab samples from locations 3 and 8 and in all oyster samples from loaction 5; Zn-65 was also observed in some oyster samples from location 5g and Co-6B appeared in sediment samples in a pattern
. similar to that observed in the past.
In order to assess ~ the plant's contribution to the ambient radiation
, . levels of the surrounding environment, dose calculations were performed using the plant's affluent release data, on site meteorological data, and appropriate pathways. The results of these dose calculations indicate:
- a. a maximum thyroid dose (via inhalation and garden vegetable l

- c. a maximum whole body dose (via all liquid pathways) of B.83 mrem, which is less that 8.2% of the acceptable limit of 25 mrem / year (48 CFR 199).
Thus it is concluded, based upon the levels of
- radioactivity observed and the various dose calculations performed, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1983 did not cause any significant changes in the radionuclide inventory of the surrounding environment or in the ambient radiation levels.

B. INTRODUCTION Baltimore Gas and Electric Company (BG&E) has been' conducting a radiological environmental monitoring program in the environs of the Calvert Cliffs Nuclear Power Plant since the summer of 1978. The Calvert Cliffs site is an operating nuclear generating station consisting of two PWR units. Unit 1 achieved criticality on October 7,1974 and commenced commercial operation in May 1975. Unit 2 achieved criticality on November 38, 1976 and went into commercial' operation April 1,1977. Since July 29, 1977, .ther monitoring program has been operating under combined Environmental Technical Specifications for Units 1 and 2 (29). Prior to this date, sepaFate Environmental Technical Specifications (21, 22) were in effect for each unit.
~
Resu1ts of the monitoring program for the preoperational and previous operational periods through December 31, 1982, have been reported in a series of documents (1-19).
Results of the monitoring program for the current operational period of January 1,1983 through December 31, 1983 are includerd in this report. - The report presents - the , type and number of samples analyzed, the analyses performed (see Tables 1 and 2 for -a summa y of the surveillance program),
the ~ relative positon of, samplintj ' locations with respect to the Calvert Cliffs , Nuclear Power Plant-(see Appendix A for relevent maps and figures),
and the data generated during 1983 (see Appendix B for the tabulation of the raw data collected). Interpretation of the data and conclusions are presented in the body of this report.
C. PROGRAM :
The environmental surveillance data collected during this reporting period were compared with that generated in previous periods in evaluating the environmental radiological impact of the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during the year 1983.
C.1 Objectives l

and shown in Figure A-2. All samples were collected by consultants to, or personnel of, Baltimore Gas and Electric Company according to BG&E l operating procedures (22). . Radiochemical analyses were performed by Teledyne Isotopes and BG&E in accordance with established laboratory
- _p rocedures (24,25).
Ambient radiation measurements were made by BG&E personnel in accordance with BG&E operating procedures (25). These measurements were made with ,
- thermoluminescent dosimeters as previously described (19).

C.3 Data Interpretation I l
l Analytical data generated during the program are routinely evaluated. In 1 i the interpretation of the data several factors are important and are j discussed here to avoid repetition in the sections that follow.
It is a characteristic of environmental monitoring data that many results occur at or below the minimum detectable level (MDL). In this report, all results at or below the relevant MDL are reported as being "less than" the MDL value.
Annual means, ranges, and typical MDL's are presented for each type of analysis and for every sample media in Table 1. (In the case of gamma
= spectrometry, if no activity of a particular nuclide was found, no average was calculated for that nuclide.) Results of individual analyses are also presented with applicable standard deviations in the data tables of i Appendix B.
j C.4 , Program Exceptions No rooted aquatic plants were found during 1983.
Samples of crabs were unavailable during the first quarter of 1983.
I Edible fish samples were unavailable during the first and second quarters l of 1983.

- January 1 - December 31, 1983 Dockets Nos. 58-317/318 RESULTS AND DISCUSSIONS All environment.a1 samples were either analyzed by Teledyne Isotope's
' laboratory procedures (24) or BG&E laboratory procedures (25). The analytical results for this reporting period, presented in Appendix B and also summarized on an annual basis in Table 2, have been divided into four categories - aquatic environment, atmospheric environment, terrestrial environment, and external radiation.
D.1 Acr2atic Environment The aquatic environment surrounding the plant was monitored by analyzing l samples of bay water, aquatic organisms, and bottom sediment. These samples were obtained from various sampling locations on the Chesapeake Bay near the plant.
D.1.a Bay Water Monthly bay water samples were taken from two locations; the Plant Intake area (location B), and the Plant Outfall area (location 7). These samples
. were analyzed for H-3, gamma emitters, and Sr-89 and Sr-98.
Monthly analyses for H-3 showed ; detectable concentrations in only four
. , . . samples collected from location 7. These concentrations ranged from 184+/-118 to 381+/-117 pCi/1, and they are similar to the results observed
. in both the preoperational (6) and previous operational periods (19).
Monthly analyses for gamma emitters exhibited no detectable concentrations of any fission or activation products in these samples.
4 Quarterly analyses ,for radiostrontium exhibited no detectable concentrations of these nuclides in any of the composited samples.
. D.1.b Actuatic Ortjanisms
, . Quarterly samples of aquatic organisms were taken from five locations; the j pound nets south of Cove Point (location 1), Kenwood Beach (location 3),
i Rocky Point ~(location 4), Camp Conczy (location 5), and Plant Intake area (location 8). . .The edible portions of these. samples were analyzed for
- gamma emitters, and samples of fish bones were analyzed for Sr-89 and I. Sr-99.

. January 1 - December 31, 1983 Docket Nos. 50-317/318 the four locations exhibited detectable concentrations of Ag-110m. For crab samples the Ag-11Bn concentrations ranged from 18+/-13 to 24+/-14 pCi/kg, and -for oysters the Ag-118m ranged from 24+/-8 to 535+/-30 pCi/kg, -
with the highest concentration observed at location 5. In addition to
. Ag-110m, detectable concentrations of the activation product 2n-65 (ranging from 68+/-34 to 96+/-33 pCi/kg) were also observed in some of the oyster samples from location 5. The concentration levels of these nuclides are similar to levels observed in previous years (15-19), and their presence is probably plant-related.
Quarterly radiostrontium analyses of the bones of fish samples showed no measureable concentrations of Sr-89. Strontium-98 on the other hand, was observed in most samples in the range of 3.5+/-1.6 to 15+/-5 pCi/kg.
These results are similar to the general patterns observed in both the preoperational (6) and previous operational periods (19).
D.1.c Sediment Quarterly ' sediment samples were taken from four locations; Camp Conoy (location 5), Long Beach (location 6), Plant Intake area (location 8), and Plant Outfall area (location 7). These samples were analyzed for gamma emitters and Sr-89 and Sr-99.
Quarterly analyses for gamma emitters in these samples revealed the presence of the following radionuclides: Cs-137 in all samples from all locations, ranging from 178+/-51 to 1183+/-124 pCi/kg; Co-60 in most of the samples from all locations, ranging from 121+/-188 to 427+/-132 pCi/kg; and Ce-144 in the first quarter sample from the control location 6 at a concentration of 541+/-378 pCi/kg. The range of Cs-137 concentrations exhibited are similar to the ranges observed in the preoperational (6) and prior operational (19) periods. In addition, the presence of Ce-144 in a sample obtained 'in the first quarter of - the year is probably related to past nuclear weapons testing, since this radionuclide is typical of the
" main fallout nuclides", and it appears to follow the same trends observed in previous reporting periods (16-19). On the other hand, Co-60 is .among the activation and fission products released from the plant in routine ' radioactive discharges. Its range of concentrations is similar to those observed in previous operational periods (19).
-Quarterly radiostrontium analyses of the sediment samples exhibited no measurmable concentrations of either Sr-89 or Sr-90.
D.2 Atmospheric Environment .
The . atmospheric environment was monitored by analyzing samples of air particulate filters, silver zeolite cartridges, and precipitation samples. .
These samples were collected from various locations surrounding the plant.-

D.2.a Air Particulate Filters Weekly composite air filters were collected from seven locations; On Site !
(location 17), On Site (location 18), Knotty Pine (location 19), Lusby (location 28), Long Beach (location 21), Cove Point (location 22), and Taylors Irland (location 23). These samples were analyzed for beta ,
activity, gamma emitters, and Sr-89 and Sr-98. '
Weekly analyses for beta activity on air particulate filters revealed that the annual range of data for each location was much lower than the annual ranges exhibited in previous years (16-19). This is most probably due to a .
gradual decrease of atmospheric fallout from past nuclear we., pons testing.
The current ranges are similar to those observed prior to September,1976 when the ' Peoples Republic of China detonated the first of a series of nuclear weapons (12).
Monthly analyses for gamma emitters showed no measureable concentrations of any fission or activation by products in these samples.
Quarterly radiostrontium analyses of air particulate filters exhibited no
. detectable concentration of Sr-89 in any of the samples and only two detectable concentrations of Sr-90 in the second and fourth quarter samples from location 29 ar.d 21, both of which were very close to the MDL
. for this type of analysis.
D.2.b Air Iodine .
Weekly composite radiciodine samples were collected from five locations; On Site (location 17), On Site Gocation 18), Lusby (location 20), Cove Point Gocation 22), and Taylors Island (location 23).
Radiciodine analyses performed on the samples from all locations exhibited no detectable concentrations of I-131.
~ D.2.c. Precipitation -
Monthly composite precipitation samples were collected from one site, On Site (location IS) and were analyzed for gross beta, H-3, gamma emitters, and Sr-89 and Sr-99.
Monthly analyses for beta activity in precipitation samples revealed that the annual range of data for this location was less than the ranges of data in recent years U3-19) and similar to the ranges observed prior to the start of the nuclear weapons testing by the Peoples Republic of China (12).
Quarterly analyses for H-3 in composites of these samples revealed no measureable concentrations of this radionuclide.

January 1 - December 31, 1983 Docket Nos. 58-317/318 Monthly analyses for gamma emitters showed no detectable concentrations of any fission or activation products in these samples.
Quarterly radiostrontium analyses of the composited precipitation samples exhibited no detectable presence of either Sr-89 or Sr-90 in any of the samples tested.
D.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of milk, vegetation, soil, and well water. These samples were collected from various sampling locations near the plant.
D.3.a Milk Milk samples were collected monthly when available from two locations; a nearby farm (location 15) and a local store in the town of St. Leonard (location 38). These samples were analyzed for I-131, gamma emitters, and Sr-89 and Sr-98.
Analyses for I-131 in these samples showed no detectable concentrations of this radionuclide in any of the samples from -either location. Typical MDL's were in the range of B.1 to B.3 pCi/1. In addition, further analyses ,
of these samples for other gamma emitters revealed no measureable concentrations of any fission or activation products.
Radiostrontium analyses of the milk samples exhibited no detectable presence of Sr-89 in any of the samples. The analyses did reveal the presence of- Sr-98 in all of the milk samples from both locations, ranging l
from 1.2+/-9.4 to 5.9+/-9.9 pCi/1. The presence of Sr-98 is most probably l due to fallout from past nuclear weapons testing.
l D.3.b Vegetation I Vegetation samples were collected from three locations; On Site (location 14); . a nearby. farm (location 15), and another nearby farm (location 16)..
.These samples were analyzed for gamma emitters and Sr-89 and Sr-98.
Analyses for gamma emitters in these samples revealed the presence of measurable concentrations of Cs-137 in two of the vegetation samples l - (viz., 9.2+/-9.2 pCi/kg in the August cabbage sample from location 14 and l 41+/-15 pCi/kg from the November tobacco sample from location 16). These results are similar to those observed in previous operational periods (19) -
and are probably the result of fallout from past nuclear weapons testing.
Radiostrontium analyses of vegetation samples revealed no detectable presence of Sr-89 in any of the samples. On the other hand, the analyses revealed the presence of Sr-98 in most of the vegetation samples, ranging l from 14+/-2 to 110+/-10 pCi/kg. This range of Sr-9B results indicate the same general patterns observed in previous years (16-19) and is most 8

January 1 - December 31, 1983 Docket Nos. 50-317/318 probably attributable to fallout from past weapons testing.
D.3.c Soil Soil m.mples were taken from three On Site locations; 11, 12, and 13.
These samplos were analyzed for gamma emitters and Sr-89 and Sr-90.
Analyses for gamma emitters revealed the presence of Cs-137 in most of these samples, ranging from 74+/-51 to 478+/-68 pCi/kg. These results are similar to those observed in the preoperational (6) and previous operational periods G9) and are probably due to the deposition of fallout i from past nuclear weapons testing.
Radiostrontium analyses of the soil samples showed no detectable concentrations of Sr-89, and only a single detectable concentration of Sr-99 in the June sample from location 11. The Sr-90 result is similar to i
the results observed in both the properational (6) and previous operational (19) periods and is probably related to fallout from past nuclear testing.
. D.3.d Well Water Quarterly . well water samples were collected from five locations;
. Chesapeake Country Club nocation 2), On Site Gocation 12), Long Beach Gocation 21), and White Sands Club Gocations 25A and 25B). These samples were analyzed for H-3 and gamma emitters.
Quarterly analyses for H-3.and gamma emitters in these samples showed no measureable concentrations of any fission or activation by-products.
D.4 External Radiation Thermoluminescent dosimeters were ~ collected monthly from 13 locations surrounding the plant, namely: Plant Outfall Gocation 7), On Site Gocation i
17), On Site Gocation 18), Knotty Pine Gocation 19), Lusby Gocation 20),
Long Beach Gocation 21), Cove Point Gocation 22), Taylors Island Gocation
- 23), On Site Gocation 24), White Sands Club Sign Gocation 25), St. Leonard i Gocation 26), Solomons . Island (location 27), and Bertha Church Gocation 28).
! The dosimeters were read for external radiation dose rate in millirem (mR).
The TLD. data for each location are compiled in Table B-14 and are presented on an annual basis in Table 2. The current means and ranges expressed in Table 2 were compared with the means and ranges for the span of years from 1978 to 1982 G5-19). This comparison revealed that the ' means and ranges for 1983 were similar to those observed in the five preceding years.

January 1 - December 31, 1982 Dockets Nos. 50-317/318 surrounding the plant during 1983. Most of these observations were attributed to the fallout from atmospheric nuclear weapons testing, and others were related to the operation of the plant (viz., H-3 in bay waterg .
Zn-65 and Ag-110m in shellfish samples; and Co-68 in sediment samples).
In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calculations were performed using the plant's effluent release data, on site meteorological data, and appropriate pathways. The results of these dose calculations indicates
- a. a maximum thyroid dose (via inhalation and garden vegetable pathways) of S.15 mram at location 14, which is 0.27. of the acceptable limit of 75 mrem / year as specified in 48 CFR 190 Environmental Radiation Protection Standards for Nuclear Power Operations, and a maximum thyroid dose (via milk pathway) of B.87 mrom at location 15, which is less than 2.17. of the acceptable limit of 75 mrom/ year (40 CFR 198);
- b. a maximum whole body gamma dose of B.96 mrem at location IS, which is less that B.3% of the acceptable dose .of 25 mrem / year (48 CFR 199); -
- c. a maximum whole body dose (via all liquid pathways) of 0.03 mrom, which is less than B.27. of the acceptable limit of 25 -
arem/ year (48 CFR 198).
Thus it is concluded, based upon the levels of radioactivity observed and the various dose calculations performed, that the operation of Calvert Cliffs Nuclear - Power Plant Units 1 and 2 during 1983 did not cause any significant changes in the radionuclide inventory of the surrounding environment or in the ambient radiation levels.
