SUMMARY
During this operating period for Calvert Cliffs Nuclear Power Plant Units 1 and 2, a total of 674 analyses were performed on 606 environmental samples, and 1104 thermoluminescent dosimeters (TLD's) were analyzed for ambient radiation exposure rates. In addition, 152 analyses were performed on 126 quality assurance samples as part of the Environmental Protection Agency's Cross-Check Program and our internal Quality Assurance Program with Teledyne Isotopes Company. The samples collected from the aquatic environment included bay water, fish, oysters, and shoreline sediment samples. Bay water was analyzed for tritium and gamma emitters. Fish, oysters, and shoreline sediments were analyzed for gamma emitting radionu-clides.
', Monitoring the atmospheric environment involved sampling the air at various locations surrounding the plant. Air particulates and gaseous iodine were collected on glass fiber filters and silver zeolite molecular sieve cartridges, respectively. The particu-late filters were analyzed for beta activity and gamma emitting nuclides. The molecular sieve cartridges were analyzed for airborne I-131.
Samples from the terrestrial environment included only vegetation samples, which were collected and analyzed for gamma emitters and I-131. Measurements of external radiation we re performed by analyzing TLD's from twenty-three locations surrsunding the plant. Low levels of various man-made fissior, and activation by-products were observed in the environment surrounding the plant during the year 1989. Some of these observations: Were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plar.t (viz., Ag-llom in oyster samples and co-60 in a vegetation sample). In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calcula-tions were performed using the plant's effluent release data, on site meteorological data, and appropriate pathways. The results of these dose calculations indicate: 4 L . 1
t January 1 - December 31, 1989 l Docket Nos. 50-317/318 .
- a. a maximum thyroid dose of 5.26E-01 aren via liquid and gaseous pathways which is about 0.7% of the acceptable limit of 75 area /yr as specified in 40 CFR 1901
- b. a maximum whole body dose of 1.13E-01 aren via !
liquid and gaseous pathways which is about 0.5% of the acceptable limit of 25 area /yr as specified in I 40 CFR 190;
)
- c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 6.74Ea01 area from the GI tract and skin, respectively. This dose was about 2.7% of the allowable limit of 25 i area /yr as specified in 40 CFR 190.
Thus it is concluded, based upon the levels of radioactivity 1 observed and the various dose calculations performed, that the
- operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 did -
not cause any significant impact on the surrounding environment > during the year 1989. ' t Y e 1 l

B. INTRODUCTION Baltimore Gas and Electric Company (BG&E has been conducting a radiological environmental monitoring pro) gram in the environs of the Calvert Cliffs Nuclear Power Plant since the summer of 1970. The Calvert Cliffs site is an operating nuclear generating . station consisting of two pressurized water reactors. Unit 1 ! achieved criticality on October 7, 1974 and commenced commercial ; operation in May _1975. Unit 2 achieved criticality on November . 30, 1976 and went into commercial operation April 1, 1977. Originally the radiological environmental monitoring program was conducted under separate Environmental Technical Specifications (26,27). On July 29, 1977 the monitoring program began operation under a combined set of Technical Specifications (28). The program has operated as such until March 1 1985 when the
. Environmental Technical Specifications were rev1 sed to reflect a
~
new generic format for radiological environmental monitoring adopted by the Nuclear Regulatory Commission (29). Changes in
, the program (sample locations, sample types, and/or sampling
, frequencies) have been implemented to conform to these revisions. '
Results of the monitoring program for the preoperational and previous operational periods through December 31, 1988 have been reported in a series of documents (1-25).
- Results of the monitoring program for the current operational period of January 1, 1989 through December 31, 1989 are included in this report. The report presents the content of the +
Radiological Environmental Program (Table 1), the sampling locations (Appendix A), the summary of the analytical results of 1988 (Table 2), a compilation of the analytical data for 1989 s l (Appendix B), the results of the EPA Intercomparison Program and the Quality Assurance Program (Appendix C) , the results of the Land Use Survey (Appendix D), and a compilation of the analytical data for extra samples collected in 1989 Appendix E). Interpretation of the data and conclusions are pre (sented in the body of the report. The environmental surveillance data collected during this reporting period were compared with that generated in previous periods whenever possible in order to evaluate the environmental radiological- impact of the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during the yecr 1989. m 3 l l I l

Jcnuary 1 - December 31, 1989 Docket Nos. 50-317/318 D. RESULTS AND DISCUSSION All the environmental samples collected during the year were The analytical analyzedforusing BG&E's laboratory period areprocedures presented (32)in Appendix B and results this reporting also summarized on an annual basis in Table 2. of discussion, For the purposes the analytical results are divided into four categories. The categories are the Aquatic Environment, the Atmospheric Environment, the Terrestrial Environment, and Exter-nal Radiation. These categories are further divided into subcat-agories according to sample type (e.g., Bay Water, Aquatic Organisms, etc. for the Aquatic Environment) . D.1 Acuatic Environment The aquatic environment surrounding the plant was monitored by analyzing samples of bay water, aquatic organisms, and shoreline 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 during the year. These locations are the Intake Area (sample code Wal) and the Discharge Area (sample code Wa2). The samples were obtained from a composite sampling system operating at each location for the entire sampling period. These samples were analyzed for tritium and gamma emitters.
The tritium analyses, performed on quarterly composites of the monthly bay water samples, showed no detectable concentrations of tritium in any of the samples analyzed. Monthly analyses for gamma emitters exhibited no detectable concentrations of either fission or activation products, which j could be related to the operation of the plant. D.1.b Acuatic Oreanisms l-Samples of aquatic organisms were obtained from four locations during - the year. Samples of fish, when in season, were . taken from the Intake-Discharge Area (samples code Ial and Ia2), and from the Patuxent River (sample codes Ia4 and Ia5). Oyster samples were obtained quarterly from Camp conoy (sample code Ia3) and Kenwood Beach (sample code Ia6) . Edible portions of these samples were analyzed for gamma emitters. 5
l Jcnuary 1 - Decemb0r 31, 1989 : Docket Nos. 50-317/318 , ! Gamma spectrometric analyses of the fish from both locations i exhibited no detectable concentrations of any fission or activa-tion products. l Quarterly analyses for gamma emittere in oyster, showed detect-able concentrations of a plant-related radionuclide, Ag-110m, in samples obtained from Camp conoy (Ia3) . The observed concentra-tions ranged from 35+/-10 to 103+/-16 pci/kg. The presence of this radionuclide at these concentration levels is typical of that observed in previous operating periods (7-25). D.l.c Shoreline sediment Semiannual shoreline sediment samples were taken from one loca-tion during the year. This location is the shoreline at camp conoy (sample code Wb1) . The samples obtained from this location i were analyzed for gamma emitters. Gamma spectrometric analyses of these samples exhibited no detectable concentrations of any fission or activation products. - l l D.2 Atmoseheric Environment
~
The atmospheric environment was monitored by analyzing air 1 particulate filters and silver zeolite cartridges (for trapping radioiodine species). These samples were collected from various locations surrounding the plant. > D.2.a Air Particulate Filters Weekly composite air particulate filter samples were collected from five locations during the year. These locations are on Site (sample code A1), Camp Conoy Road Near the Emergency Siren l (sample code A2), Bay Breeze Road (sample code A3), Lusby (sample code A4), c-d at the Emergency offsite Facility (sample code A5). These samples were analyzed for beta activity and gamma emitters. Weekly analyses for beta activity on air particulate filters collected from all five locations showed values charateristic of background levels (7-25) . t_ Gamma spectrometric analyses of monthly composited air parti-culate samples exhibited no detectable concentrations of any l fission or activation products in any of these samples. l' D.2.b Air Iodine i Weekly composited silver roolite cartridges (for trapping { radioiodine species) were collected from five locations during 6 l
-- & ----p
Jtnunry 1 - Dec:aber 31, 1989 Docket Nos. 50-317/318 the year. These locations are On site (sample cods A1) , Camp Conoy Road Near the Emergency Siren (sample code A2), Bay Breeze Road (sample code A3), Lusby (sample code A4), and at the Emer-gency Offsite Facility (sample code A5). These ramples were analyzed for radioiodine species. Weekly radiciodine analyses of silver zeolite cartridges collect-ed from all five locations exhibited no detectable concentrations of I-131. { D.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation collected monthly, when available, from various samp-ling locations near the plant. D.3.a vecetation Vegetation samples were collected from three locations during the year. These locations are Bay Breeze Road (sample codes Ibl,
' Ib2, and Ib3), On Site Before the Entrance to Camp Conoy (sample codes Ib4, Ib5, and Ib6), and the Emergency Offsite Facility
. (sample codes Ib7, Ib8, and Ib9) . These samples were analyzed
, for gamma emitters, including analyses for I-131.
Gamma spectrometric analyses of these samples revealed the presence of only a single plant-related radionuclide in one l vegetation sample. Cobalt-60 was observed in a brussel sprout sample taken from the garden located at the Entrance to Camp Ccnoy (Ib5) during the month of March. The concentration of this radionuclide was 26+/-11 pCi/kg. This result is very low and : well within the range of MDL's for Co-60 in vegetation (See Table B-9). Cobalt-60 has been sporadically observed in the past (7,25) in vegetation samples obtained from farms in the surround-ing area. At this very low level it poses no significant radiological consequence. D.4 External Radiation Thermoluminescent dosimeters were co'lected monthly from twenty-three locations surrounding the plant. The locations are On Site Along the Cliffs (sample code DR1), Route 4 Auto Dump (sample code DR2), Giovanni's Tavern (sample code DR3), White Sands (sample code DR4), John's Creek (sample code DR5), Lusby (sample code DR6), On Site (sample code DR7), On Site Near the Emergency Siren (sample code DRB), Bay Breeze Road (sample code DR9), Decatur and Calvert Beach Roads (sample code DR10), Dirt Road off Mackall and Parran Roads (sample code DRll) , Mackall and Bowen Roads (sample code DR12) , Wallville (sample code DR13), Rodney l

Point (sample code DR14), Mill Bridge and Turner Roads (sample code DR15), Appeal School (sample code DR16) , Cove Point and Little Cove Point Roads (sample code DR17), Cove Point (sample code DR18), Long Beach (sample code Dulo), on Site Near Shore (sample code DR20), Emergency Offsite Facility (sample code DR21), Solomons Island (sample code DR22), and Taylors Island (sample code DR23). A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data (7,25) shows that no plant-related contribution to the measured exposure rate for 1989 was discernible. E. Conclusion Low levels of various man-made fission and activation by-products were observed in the environment surrounding the plant during the year 1989. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plant (viz., Ag-110m in oyster - samples and Co-60 in a vegetation sample). - Histcrical trends for tritium in bay water, Ag-110m and X-40 in
- oyster samples, nuclear fallout in the Calvert Cliffs area, and TLD data from selected sites are depicted in Figures 1 through 4.
As can be seen from these figures, the plant made only negligible radiological contributions to the surrounding environment during its entire operation. In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calcula-tions were performed using the plant's affluent release data, on site meteorological data (see X/Q and D/Q values presented in Figures 5 and 6), and appropriate pathways. The results of these dose calculations indicates o Gaseous Pathways A maximum thyroid dose of 4.93E-01 mram to an infant via the plume, ground, vegetable, meat, cow milk, goat milk, and inhalation pathways at the nearest dairy cow located 4.8 km SSW of Calvert Cliffs, which is about 0.7% of the acceptable limit of 75 arem/ year as specified in 40 CFR 190, " Environmental Radiation Protection Standards for Nuclear Power Operations". A maximum whole body gamma dose of 5.47E-02 mrem at the onsite boundary, 2.1 km S of Calvert Cliffs, which
- l j
Jcnunry 1 - DecembOr 31, 1989 Docket Nos. 50-317/318 i is about 0.2% of the acceptable dose limit of 25 arem/ year as specified in 40 CFR 190. A maximum dose to any crysn,-in this case skin, of 1.27E-01 arem at the enc.te boundary, 2.1 km S of Calvert l Cliffs, which is about 0.5% of the acceptable dose limit J of 25 mrum/ year as specified in 40 CFR 190. I o Licuid Pathways i A maximum thyroid dose of 3.30E-02 arem, which is about ! 0.04% of the acceptable dose limit of 75 mram/ year as specified in 40 CFR 190. { A maximum whole body dose of 5.85E-02 arem via all liquid pathways, which is about 0.2% of the acceptable dose limit of 25 mram/ year as set forth in 40 CFR 190. A maximum dose to any organ, in this case the GI tract, -
- of 6.20E-01 mram, which is less than 2.5% of the
- acceptable dose limit of 25 mrem / year as specified in 40CFR 190.
o Gaseous and Licuid Pathways Combined A maximum thyroid dose of 5.26E-01 arem via liquid and gaseous pathways, which is about 0.7% of the acceptable limit of 75 mrea/ year as specified in 40 CFR 190. A maximum whole body dose of 1.13E-01 mram via liquid and gaseous pathways which is about 0.5% of the acceptable limit of 25 mram/ year as specified in 40 CFR 190. A maximum calculated done to all othar organo via lignid and gaseous pathways was equal to 6.74E-01 arem from the GI tract and skin, respectively. This dose was about 2.7% of the allowable limit of 25 aren/ year as specified in 40 CFR 190. In all cases, the calculated doses are a small fraction of the applicable limitu specified in 40 CFR 190. On this basis it is
- concluded that the operation of Calvert Cliffs Units 1 and 2 met the criteria of 40 CFR 190 during 1989.
In addition it is also concluded, based upon the levels of radioactivity observed and the various dose calculations per-formed, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1989 did not cause any significant impact on the environment. i 9

l January 1 - December 31, 1989 i Docket Nos. 50-317/318 l i l APPENDIX C 1 I l Appendix C contains Table C-1 which is a compilation of the results of BG&E laboratory's participation in the Environmental Protection i Agency's Cross-Check Program during the period January 1, 1989 to December 31, 1989. It also contains Table C-2 and Table C-3 which ! together form a compilation of the results of BG&E laboratory's participation in a Quality Assurance program setup with Teledyne Isotopes Company during the same period. The Teledyne operating ' procedures are described in reference 31. As can be readily seen in Tables C-1 and C-2 the laboratory's
, results agree quite well with both the EPA Cross-Check results and l the Quality Assurance results from replicate and split-sample t analyses.

Discussion A Land Use Survey.was conducted during the growing season of the year 1989 to identify, within a distance of 8 km, the location of the nearest milk animal,2 the nearest residenco, and the nearest garden greater than 50 m in each of the nine sectors over land. A detailed description of the Land Use Survey -is given in a separate document (36). The position of the nearest dairy cow, residence, and garden in each sector up to B km are given.in the ; above table. .
-The closest residence is situated in the WSW sector, which is one of the least prevalent wind directions. The closest garden is situated in the SSW sector. In the's, SSE, and SE sectors there is the. highest probability of wind b?,owing from the direction of the plant. The two gardens used for vagetable samples by.the-Radiological Environmental Program have been.placed in . the sectors with tN highest X/Q. One sampling garden is located in
.- the S sector at _ a distance of 0.7 km,'and another is situated near' the site boundary between ' the SSE and SE sectors at a-distance of 2 6 km from the plant. These two sampling sites are considered good indicator locations for radi6 active depositions around the plant. The mi1k cow and milk goat within a distance of 8 km.from the plant are mituated in the SSW sector, at 4.8 km from the release point. This sector is closely monitored by two TLD's (DR6 and DR15) and by an air sampler (A4). Consideration e

At - this . location forage - samples - were collected and analyzed (see Table E-7 in Appendix E). Milk samples were not obtainable. The dose assess-ment using 1989 meteorological data was performed, and no signif-icant impact-from the-operation of the plant was found. 4 i 9 9 h e 75

APPENDIX E r Appendix 1E is a presentation of the analytical results for a number of additional samples collected in the environs of calvert Cliffs-Nuclear-Power Plant during the year 1989. These extra samples.are not required by the Environmental Technical Specifications (26-29), but they vere collected and analyzed in order to maintain the= historical continuity for samples and sampling pathways-discontinued when the Environmental Technical Specifications were ' changed in March, 1985, and to broaden the range'of our monitoring program. *
- In general, the results in the following tables continue the '
historical-trends observed in the past, and in those cases where new sampling- sites were established, . the levels observed are-
' similar-to those observed at the official sites of the.
Environmental Monitoring Program. [ l l i l' f.: p h . L- -' 76 l 3
