1 pathways. The results of these dose calcuir,tions indicates

a. a maximum thyroid dose (via inhalation and garden vegetable pathways) of 0.22 mrem at location 14, which is less than 0 3% of the acceptable limit of 75 mrem / year as specified in h0 CFR 190 Environmental j Radiation Protection Standards for Nuclear Power Operations;

Thus it is concluded, based upon the levels of radioactivity ' bserved o and 4

the various dose calculations perfonned, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1982 did not cause any significant changes in radionuclide inventory of the surrounding envirorseent or in the ambient radiation levels of critical pathways.

B. INTRODUCTION Baltimore Oas and Electric Company (BG&E) has been conducting a radiological enviromental monitoring program in the environs of the-Calvert Cliffs -

Nuclear Power Plant since the summer of 1970. Results of the anaIyses of enviromental samples for the preoperational and operational periods through December 31, 1981, have been reported in a series of documents (1-18)._  ;

this report presents the type and number of samples analyzed, the analyses performed (see Table 1 for a summary of the surveillance program) and the data generated durir.g 1982. Interpretatica of the data and conclusions are presented.

Appendix A summarizes the sample media and relative sampling locations with respect to the Calvert Cliffs Nuclear Power Plant (Table A-1 and Figure A-1).

Figure A-2 shows the location of the Calvert Cliffs Nuclear Site in relation to the Chesapeake Bay and Southern Maryland. The Calvert Cliffs site is an operating nuclear generating station consisting of two PWR Units. Unit 1 achieved criticality on October 7,197h, and commenced comercial operation in May 197$. Unit 2 achieved criticality on November 30, 1976, and went into comercial operation April 1,1977. Since July 29, 1977, we have been operating 4

under combined Environmental Technical Specifications for Units 1 and 2 (19).

Prior to this date, separate Enviromental Technical Specifications (20, 21)

.'. were in effect for each unit.

t'- C. P100 RAM The enviromental surveillance data collected during this reporting period were compared with that generated in previous periods in evaluating the environ-i mental radiological impact of the operation of Cal mrt Cliffs Nuclear Power Plant Units 1 and 2.

C.1 Objectives The objectives of the operational radiological environmental program ares

a. To determine whether any statistically significant increase occurs in the concentration of radionuclides in important pathways,
b. , To detect any measurable buildup of long-lived radionuclides in the environment,
c. To monitor and evaluate ambient radiation levels,
d. To verify that radioactivity and ambient radiation levels attributable to the plant are within the limits specified in the Technical Specifications ~(19) and the Environmental Radiation Protection Standards as set forth in h0 CFR Part 190.

C.2 Sample Collection l The locations of the individual sampling stations are listed in Table A-1 and shown in Figure A-2. All samples were collected by consultants to, or personnel of, Baltir. ore Gas and Electric Compaq according to BG&E operating procedures (22). Radiochemical analyses were performed by 181C and BO&B.

Ambient radiation measurements were made by Baltimore Gas and Electric Compay personnel in accordance with an operating procedure (25). These measurements were made with thermoluminescent dosimeters as previously described (10).

i

'C.3 Data Interpretation Analytical data generated during the program are routinely evaluated. In the interpretation of the data several factors are important ard are discussed here to avoid repetition in the sections that follow.

It is characteristic of environmental monitoring data that many asults occur at or below the minimum detectable level (MDL). In this report, all results occurring at or below the relevant MDL am reported as being "less than' the i hDL value.

Annual means, range and typical MDL's are presented for each type of analysis 4

for every sample media. Results of individual analyses are also presented with applicable standard deviations.

, , In the case of gcuma spectrometry, if no activity of a particular nuclide was found, no average was calculated for that nuclide.

l C.h Program Exceptions No milk samples, vere available during 1982, because tIiere were no milk cows within five miles of the Plant.

No rooted aquatic plants were found during 1982.

Samples of crabs were unavailable during the first quarter of 1982.

Edible _ fish samples were unavailable during the first quarter of 1962, because the commercial pound nets south of Cove Point were not deployed during tbat period.

Bay water samples for January 1982 could not be collected. because the Bay

- was icy during that period.

Jcnu ry 1 - Dectmber 31, 1982 Docket Nos. 50-317/318 D. RESULTS AND DISCUSSIONS All environmental samples were either analysed by IRC laboratory procedures (23) or BO&E laboratory procedures. (2h). The analytical results for this reporting period, presented in Appendix B and also sununarised on an armual basis in Table 2, have been divided into four catagories -- aquatic, atmos-pheric, terrvsstrial environment, and external radiation.

D.1 Aouatic Environment The aquatic environment currounding the plant was monitored by analysing 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.l.a Bay Water Monthly bay water samples were taken from two locations; the Plant Intake area (location 8), and the Plant Outfall area (location 7). These samples were analysed for H-3, gama emitters, and Sr-89 and Sr-90.

Monthly analyses for H-3 in these samples exhibited concentrations ranging from <121 to 572tllh pCi/l for location 7 and from <119 to 3092117 pCi/l for location 8. Most of the H-3 results observed in samples obtained from

-* . both locations were less than the min 4== detectable limit. The few positive  ;

results observed in these samples are similar to the results observed in both

, the preoperational (6) and previous operational periods (18).

Monthly analyses for gamma emitters in these samples showed only the detect-able concentration of Co-58 at 5.1-1.1 pCi/1 in the May sample from location

7. The presence of Co-58 in this sample is probably plant related.

Quarterly analyses for radiostrontium showed a single detectable concentration of Sr-89 (viz., 1.311.2 pCi/1 in the first quarter composite sample from location 8), and a single detectable concentration of Sr-90 (viz., 1 9 10.7 pCi/1 in the second quarter composite sample from location 7). The detectable concentration of Sr-89 is similar in magnitude to that observed in prior operating periods (18) and may be related to plant operation. The Sr-90 concentration is comparable with concentrations observed during the preopera-tional (6) and previous operational (18) periods, and *.L probably due to residual fallout from past nuclear weapons testing.

D.1.b Aquatic Organisms Quarterly samples of aquatic crganisms were taken from five locations; the pound nets south of Cove Point (location 1), Kenwood Beach (location 3),

Rocky Point (location h), Camp Coney (location 5) and Plant Intake area (location 8). The edible portions of these samples were analyzed for gama emitters, and samples of fish bones were analyzed for Sr-89 and Sr-90.

. 4' Quarterly analyses of some of the fish samples conected during the seconde and third quarters from location 1 showed detectable concentrations of.Cs-137 in the range of 1016 to 1717 pCi/kg. This range of results is similar to Lthe ranges previously observed in both tho'preoperational (6) and prior operational periods (18). .

Quarterly analyses for gama emitters in shenfish samples fmm an sites exhibited detectable concentrations of Ag-hor., primarily in the third.and fourth quarters of the year. Ibr crab samples the Ag-nom concentrations

ranged from 1716 to 6911h pCi/kg, and for oysters the Ag-U Om ranged from n15 to 53212h pCi/kg, .with the highest concentrations observed lat location 5 In addition to Ag-110m, the activation products Co-58 (a single-quarterly 4

value of 21110 pCi/kg),and Zn 65 (ranging from 53117 to'73127 pCi/kg) were

also observed in oyster samples from location 5. The. concentration levels

. of these radionuclides are similar to levels' observed in previous years l' (15-18), and their presence is probably plant-related. : ,

1 Quarterly- radiostrontium analyses of the bones of fish samples 'showed no

, detectable concentrations of Sr-89 Strontium-90, on the other hand, was 4

observed in most samples in the range of 1511.3 to h.hth.1. pCi/kg. These l results seem to fan into the same general pattern as observed in both the- ,

l preoperational (6) and previous operational periods (18).

j 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 Outfan area (location 7). N se samples were analyzed ~for l

gama emitters and Sr-89 and Sr-90.

! Quarterly analyses for gamna emitters in these ' samples revealed the pasence E of the following radionuclides: Cs-137 in au samples from a11' locations, ranging from h0135 to 10o5286 pCi/kg; Co-60 in most of the samples from all locations, ranging from 38122 to 380191 pCi/kg; Nb-95, Zr-95, and Co-lkh I. sporadically present in samples obtained in the first quarter of the' year; and Mn-$h present in the first quarter sample taken from location 6 at a concentration of h81h8 pCi/kg. The ranges of Cs-137 concentration exhibited:

are similar to the ranges observed in.the preoperational (6) and previous
operational (18) periods.- In addition, the presence. of Nb-95, Zr-95,. and-Ce-lhh in samples obtained exclusively in the first quarter of the year is probably related to past nuclear. weapons ~ testing,isince these~ radionuclides are typical of the " main fan out nuclides" and the pattern of their appearance-l- fonows the trends observed in the previous reporting periods (16-18).- On .

the other hand, Mn-5h and Co-60 are among the activation products: released in routine radioactive discharges. The' concentrations of these activation.

, products are similar to those observed in prior operational periods _(18). . -.

Quarterly radiostrontium analyses of the sediment samples'showed only a. .

single detectable concentration of Sr-89_(vis., 1261100 pCi/kg in the second' ,

'- _q uarter-sample from location 8) .and two detectable concentrations of Sr-90 6- *

(viz., 62127 pCi/kg in the 'second quarter sample from location 6 and L0i38 pCi/kg in the second quarter sample from location 7). The.Sr-89 result may be related to plant operation, whereas the Sr-90 results are similar to the results observed in both preoperational (6) and previous operational

-(18) periods and are most probably due to fallout from past~ nuclear weapons testing.

, D.2 Atmospheric Environment

The atmospheric envirornnent was monitored by analysing samples of air partic-ulate filters, silver soolite cartridges, and precipitation samples. 'These samples won collected from various locations surrounding the plant.

i D.2.a Air Particulate Filters

) >

' Weekly composite air filters were collected from seven locations; On Site 1

(location 17), On Site (location 18), Knotty Pine (location 19), Lunby

(location 20), Long Beach (location 21), Cove Point (location 22), and l Taylors Island (location 23). These samples were analysed for beta ' activity,

, gamma emitters, and Sr-89 and Sr-90.

Weekly analyses for beta activity on air particulate filters revealed that the annual range of data for each site was much lower than the ranges exhibited l in previous years (16-18). This is most probably due to a gradual dec mase 4 . .-

of= fallout from past nuclear weapons testing. The current ranges are similar to those observed prior to the first of a series of nuclear detonations con-

' ducted by the People's Republic of China (12). . (The first test occurred on September 26, 1976.).

Monthly analyses for gasma emitters showed no detectable concentrations of any fission or activation by-products.

i Quarterly radiostrontium analyses of_ air; particulate filters exhibited the sporadic presence of both Sr-89 and.Sr-90 in detectable concentrations which are at or very near the MDL for this type of analysis. Though these results may be related to past nuclear weapons testing, they'may also-be related.in' part to plant operation.

D.2.b Air Iodine Weekly composite radioiodine samples were collected from five locations;

On Site (location 17),. On Site (location 18), Lusby (location 20),. Cove Point (location 22), and Taylors Island (location 23). .,

l b' Radioiodine analyses performed on the samples from all-locations exhibited l 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 and Sr-90.

Janusry 1 - DIccaber 31, 1982 Docket Kos. 50-317/318 Monthly analyses for beta activity in precipitation samples revealed that the annual range of data for this location was less than the ranges of recent years (13-18) and similar to the ranges observed prior to the September 26, 1976, nuclear weapons testing conducted by the People's Republic of China (12).

Quarterly analyses for H-3 in composites of these samples revealed no detectable concentrations of this radionuclide.

Monthly analyses for sacr.a emitters showed no detectable concentration of any fission or activation products.

Quarterly radiostrontium analyses of the composited precipitation samples showed no detectable concentrations of Sr-89 and only a single detectable concentration of Sr-90 (viz., 0.510.3 pCi/l in the second quarter sample).

This single detectable concentration is similar to the results observed in both the preoperational (6) and previous operational periods (18) and is most probably due to fallout from nuclear weapons testing.

D.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation, soil, and well water. These samples were collected from various sampling locations near the plant.

" ~

D.3.a Vegetation

.. Vegetation samples were collected from three locations; On Site (location 1h), a nearby farm (location 15), and another nearby farm (location 16).

These samples included corn, hay, tobacco, and wheat. They were analyzed for gamma emitters and Sr-89 and Sr-90.

Analyses for gamma emitters in these samples revealed the presence of detect-able concentrations of Cs-137 in two of the vegetation samples (viz., 37113 pCi/kg in the November tobacco sample from location 1h and 1815 pCi/kg in the November soybean samples from location 16). These results are similar to what was observed in previous operational periods (18) and are probably the result of fallout from past nuclear weapons testing.

Radiostrontium analyses of vegetation samples showed t,hree detectable con-centrations of Sr-89 (viz., 31110 pCi/kg in the July broccoli sample from location lb, 3211h0 pCi/kg in the November hay sample from location 15 and 50iL5 pCi/kg in the November hay sample from location 16). The analyses also showed detectable concentrations of Sr-90, ranging f.com 17 1h to 900+1h0 pCi/kg, in most of the samples analyzed. The Sr-89 results may be related to plant operation; whereas the Sr-90 results seem to fall within the same Eeneral patterns observed in previcus years (16,17,18) and are most probably '

attributable to tallout fron past weapons testing.

s D.3.b Soil Soil samples were taken semiannual 17 from three On Site locations; 11,12, and 13. These samples were analyzed for gama emitters and Sr-89 and Sr-90.

.-Docket Kos. 50-317/318:

Analyses for gamma emitters revealed the presence of Cs-137 in most of these samples, ranging.from LOO 126 to 250137 pCi/kg.- In addition, a single detect,-

able concentration of Nb-95 (52131 pCi/kg) was observed in the sample from location 13 obtained during the first semiannual sampling period. Both of these radionuclides are probably due to the deposition of fallout fremt past

  • nuclear weapons testing.

Radiostrontium analyses of the soil samples ~showed two detectable con:entra-tions of Sr-89 '(viz.,103187 ard 1h0176 pCi/kg in the March samples from locations 11 and 13 respectively) and two detectable concentrations of Sr (viz., ll7th8 in the March sample from location 12 and 88th3 in the December sample from location 11). The Sr-69 results'may be related to plant operation.-

The Sr-90 results are similar to the results observed in both the preoperational-(6) and previous operational.(18) periods and _ are probably related to fallout from past nuclear testing.

D.3.c Well Water Quarterly well water samples were collected from five locations
Chesapeake Country Club (location 2), On Site (location 10), Long Beach (location 21),

! and White Sands Club (locations 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 that no detectable concentrations of any fission or activation by-product were present.

D.h External Radiation Thermoluminescent dosin.eters were collected monthly from 13 locations sur-rounding the plant, namely: Plant Outfall (location 7), On Site (location 17), On Site (location 18), Knotty Pine (location 19), Lusby (location 20),

l Long Beach (location 21), Cove Point (location 22), Taylors Island (location

. 23), On Site (location 2h), White Sands Club Sign (location 25), St.' Leonard F (location 26),-Solomons Island (location 27), and Bertha Church (location 28).

, -The dosimeters were read for external radiation dose rates in mR.

The TLD data for each site are compiled in Table B-13 and are presented on

! an annual basis in Table 2. The means and ranges expressed in-Table 2 were compared with the means and ranges for the span of years from 1978 to ,

1981 (15-18). This comparison revealed that the means and ranges for.1982

, were similar to those observed in tha four preceding years.

i E. CONCLUSION Detectable concentrations of radionuclides were occasionally observed in samples from various locations during the year. Some of these. observations may be attributed to the fallout from atmospheric nuclear weapons testing l conducted in October 1980 ard in previous years, and some may be dirsctly l

related to the operation of the plant (e.g., H-3, Co-58,_and Sr-89 in bay.

+ water; Co-58, 2n-65, ard Ag-11(h in shellfish samples; Mn-$hi Co-60 and Sr-89 in sediment; ard Sr-89 in air filter, vegetation, and soil samples).

In all cases, the concentrations observed are low and, consequently, would

.have insignificant radiological impact on the surrounding environnent.

In order to assess the plant's contribution to the ambie'nt radiation . .

levels of the surrounding envirorment, dose calculations were performed using the plant's affluent 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 0.22 mrem at location ik, which is less than 0.3% of the acceptable limit of 75 mrem / year as specified in 40 CFR 190 Environmental-Radiation Protection Standards for Nuclear Power Operations; b.~ a maximum whole body gamma dose of 0.03h arem at location 18, which is less than 0.2% of the acceptable dose of 25 mrem / year (ho CFR 190);
c. a maximum whole body dose (via all liquid pathways) of 0.08 mrem, which is less than 0 5% of the acceptable limit of 25 mrea/ year (h0 CFR 190).

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 1982 did not cause ary significant changes in the radionuclide inventory of the surrounding environment or in -

' - . the ambient radiation levels of critical pathways.
