- 3. IUT2CESCTICU 3altincre Gas and Electric Ccepany (2GLE) has been ccnducting a radiological environmental nenitoring progran in the environs of the Calvert Cliffs Uuclear Power Plant cince the sunner cf 1970. Results of the analyses of environmental sanples for the preoperatienal and cperational periods thrcugh recember 31,19c0, have been reported in a series of docunents (1-17).
This report presents the type r'd number cf samples analyzed, the analyses perferned (see Table 1 for a _a= mary of the surveillance pregran) and the data generated during 1961. Interpretatien of the data and conclusiens are presented. Appendix A sunnarizes the as=ple media and relative canpling locations with respect to the Calvert Cliffs Nuclear Power Plant (Table A-1 and Pigure A-1). Figure _ A-2 shows'the location of the Calvert Cliffs nuclear Site in relation to the Chesapeake Bay and Scuthern Maryland. The Calvert Cliffs site is an operating nuclear generating station consisting of two PWR Units. Unit 1 achieved criticality en Octcher 7,197h, and cennenced ccnnercial operaticn in May 1975. Unit 2 achieved criticality en never?cer 30, 1976, and went into ce=nercial operation April 1,1977. Since July 29, 1977, we have been operating under cenbined Environmental Technical Specificaticns for Units 1 and 2 (Ic). Prior to this date, separate Envirennental Technical Specificatiens (19,20)
. were in effect fer each unit.
C. PRCGRAM The envirennantsl surveillance data cellected during this reperting pericd were ccmpared with that generated in previcus pericds to assess the environ-nental radiological impact of the operation of Calvert Cliffs Fuelear Power Plant Units 1 and 2. C.1 Objectives i The cbjectives of the operatienti radiological envircnnental progran are:
- a. To determine whether any statistically significant increase c: curs in the concentration cf radionuclides in inpertant pathways,
- b. To detect any pessible buildup of 1cng-lived radienuclides in the environnant,
- c. To nenitor and evaluate ambient radiation levels,
- d. To verify thct radicacti'.ity and anbient radiatien lavels

All sanples were collected by ectsultants te, or personnel of, Baltincre Gas and Electric Cenpr.y acccrding to 3Gh3 operating procedures (21). Radicchemical analyses were perferred by E.C and 3G53. - Anbient radiation nessurenents were nade by Baltimore Gas and Electric Cenpany personnel in accordance with an operating precedure (2h). These neasurenents were made with ther=cluninescent desineters as previcusly described (1C). C.3 Data Interpretatien Analytical data generated during the progran are reutinely evaluated. In the interpretatien of the data several facters are importa,nt and are di: cussed here to avoid repetiticn in the sectiens that follcw. ' It is characteristic of environnental menitoring data that nan-/ results cecur at cr _below the mininum detectable level (MEL). In this report, all results cccurring at or belcw the relevant MEL are reported as being "less than" the IIL value. Annual neans, range and typical lIILis are presented for each type of analysis for every sanple necia. Results of individual analyses are also presented with applicable standard deviaticns. ~ In the case of gan=a spectrcnetry, if no activity of a particular nuclide was fcund, ne averags was calculated for that nuclide. , C.L Procran Excecticns 1.'o milk sEnples, fren ecws within five miles of the plant, were available during 1981. Uo rooted aquatic plants were fcund during 1981. Sanples of crabs were unavailable during the first quarter of 1981. Edible fish sanples were unavailable during the first quarter, because the cennercial pound nets south of Cove Point were not deployed during that pericd. a 4

. . S-All environmental sa. ples were either analyzed by 320 labcratcry- precedures (22) er EGL3 lateratcry precedures (23). The analytical results for this reporting period, presented in Appendix 3 and also su= arized en an annual basis in Tabla 2, have been divided into four categories -- aquatic, at=cs-pheric, terrestrial enviren=ent, and external radiatien.
D.1 Acuatic Invirennent "he aquatic enviren=ent surrounding the plant was nonitored by analycing samples of bay water, aquatic organisns, and betten sedinent. These samples were obtained fren varicus sampling locatiens en :ne Chesapeake Bay near the plant. 3.1.8 EaY dater Monthly bay water sanples were taken frc= two locations; the Plant Intake area (locaticn 6) and the Plant Gutfall area (location 7). These sanples were analyzed for E-3, ganna emitters, and Sr-59 and 3r-90.
- !cnthly analyses fer H-3 in these sanples exhibited cencentrations ranging frca 4119 to 16C2:160 pCi/l for locatien 7 and fren 41C1 to 217:113 pCi/l fer location S. . lith tne exceptions of the April result of 16C2:160 pCi/1 and the June result of 926'102 pCi/1, both in sanples taken from iccation 7,
'all tritiun results were well within the rances cbserved in both the pre-cperational (6) and previcus cperational (17) perieds. The two cutlying
- results are pretably due to sanpling directly in the plune of the disenarge
. cencurrent with a radicactive release and befcre that release had adequately mixed with the bay.
Menthly analyses for ga na emitters in these sa ples showed cnly the detectable cctcentratien of Cc-33 at 2.7tl.3 pCi/l in the April sanp3e taken frc= iccation 7. The presence of Cc-33 in this sanple is pr bably plant
- related.
Quarterly analyses fer radicstrontiun shewed one detectable concentration of 3r-89 (viz., l.C2to.7 pCi/l in the fourth quarter sanple fren lccation 7), and two cetectable concentraticns of Sr-90 (viz.,1.26:0.37 pC1/1 and 0 70to.L3 pCi/1 in the second quarter sanples fren 1ccatiens 7 and e). The detectable concentration of '5r-09 is prcbably related to plant cperation. The 3r-90 concentratiens are ec=carable with the concentrations observed in-the precperational (6) and previeus operational (17) perieds.
' D.1.b Acuatic Organisns (narterly sanples of' aquatic crganists were taken fren five locatiens; tno pound nets scuth of Cove Point (lecatien 1), Kenwced Beach (lecatien 3), Aceky Pcint (locatien b), Canp Coney (lecation 3) and Flant Intar:e e'

....cs. 30-; 1 7/;;2 area (location 8). The edible pcrtiens of these sanples were analyzed for ganna eritters, and sanples cf fish benes were analyzed fer Sr-c9 and Sr-90.
Quarterly analyces of blue fish sanples cellected during the second, third, and fo"rth quarters fren location 1 showed cetectable cencentrations of Cs-137 ranging fren 15:5 to 27:9 pCi/kg, while the quarterly analyses of weak fish sanples during the sameeericd shewed no detectacle concentrati:ns of any ganna emitters. The presence of Cs-137 in the blue fish sanples nay be related to either racicactive discharges fren the plart er to past nuclear benb testing, er to a conbination of both of these scurces. However, it should be noted that the samples in questien were generally those of large, nature representatives of the species near the top of their food ensin, and thus the cbserved cencentratiens of Cs-137 are prcc' ably the result of a long procees of bicaccunulatien of this typical ubiquitcus falleut radionuclide. Quarterly analyses for ganna enitters in the crab sanples fren all locations and in the cyster sanples fren 1ccation 3 with tne exceptien cf the third S quarter sanplc, revealed no detectable concentrations of fission or activat,ien products in the muscle tissues. Analyses of the second and third quarter cyster sanples fren both le ation 3 and 5 shewed trace ancunts of Er-93, Eb-95, and Ru-103 which are nest probably related tc the detonatien of a nuclear cenb by the People's Republic of China in the fall cf 1960. The , analyses of cyster sanples frc: locaticn 5, en tne ether hand, revealad detectable cencentrations of Ag-11Cn ranging fren 35:3 to 60t10 pCi/kg in - all sanples, and the presence of Co-50 at a concentratien of 2005 pCi/kg and cf Zn-65 at a concentratien of 32126 pCi/kg in only the third quar,ter sample. The presence of these three radienuclides is probably plant related, ' thcugh it should be noted that in the cases of Cc-5c and Zn-63, both ccncen-tratiens bercer the nininun detectable linits of this analysis as typified in Table 3-12, and in the case of Ag-11Cn the range of results is nuch icwer thcn these observed in previcus years (15,16,17). Quarterly rcdiostrentiun analyses of the bones of fish sanples snowed one detectablo concentratien of Sr-59 (6.713.9 pCi/kg in the secend quarter blue fish sample) and showed detectable cencentrations of Sr-90, ranging frcn 5.211.7 to 1100 pCi/kg in nest of the sanples analyzed. Though the single -Sr-59 result nay be related to plant operation, it is also possible, appearing as it does at a tine when other sanple nedia indtcate the peak fallout period, to relate of depublic it to the recent nuclear weapons testing conducted by the People's China. The Sr-90 results, on the other hand, seen to fall into the sane general pattern as observed in both the .crec.eerational (6) and previcus operational periccs (17). D.l. Sediment Quarterly sodinent sanples were taken fren fcur locatiens; Cenp Cency (lecation 3), Long 3esch (locatien 6), Plant Intake area (location c), and Plant Outfall area (location 7). These sanples were analyzed fer ganna enittars and Sr-Sc i Sr-90. 6
January 1 - Zecember 31, 1951 Eceke: Ncs. 3C-317/31S ' Quarterly analyses for ganza emitters in these sanples revealed the presence of the follcwing radienuclides: Cs-137 in all samples fren all locaticns, ranging frc= 32:17 to 9CCt119 pci/kg; Co-60 in nos: cf the sanples frem all locations, ranging fren 76ch3 te h2Lt71 pCi/kg; Lb-95 and Ce-1kh sporadically present in samples taken fren the control iccation and other indicator locations; and Co-56 present in the second cuarter sample fren location 5 at a cencentratien of 131t3h pCi/kg. The ranges of the Cs-137 concentrations exhibited are similar to the ranges observed in the precpera-tional.(6) and previcus operational (17) periods. In addition, the presence of hb-95 and Ce-lhh in sanples fren both centrol and indica cr staticns is
.probably related to past nuclear bomb testing, since these radienuclidas are typical cf the "ma$n fallcut nuclices" of recent. nuclear benb testing. Cn the other hand, the presence of Co-53 and Cc-60 is probacly plant related, since they are ar.cng the activation products released in reutine racicactive discharges. The concentrations of these activation products are sinilar to those observed in previcus operational perieds (17).
Quarterly radiostrentiun analyses shewed ne detectable concentrations of Sr-59 in these sa=ples. The analyses did reveal, hcwever, the sporadic presence of Sr-90 in the range of 19tlh pCi/1 to 55t37 pCi/1, observed in sanples frc= both the centrol location and indicater locations. This range of results is similar to the ranges observed in the precperational (6) and previcus operaticnal (17,13) perieds. D.2 Atncscheric Envirennent The atnespherde environnent was menitored by analycing sanples 'of air partic-ulate filters, silver zeolite cartridges, and precipitation sanplas. These sanples were collected fren varicus locations surrcunding the plant. D.2.a Air Particulate Filters leekly cenpesite air filters were collected fren seven 1ccations; On Site (locatien 17), On Site (location 18), Knotty Pine (lecatien 19), lusby (lecation 20), icng Beach (locatien 21), Ccve Point (lecatien 22), and Taylers Island (lecation 23). These sa ples were analy:ed for beta activity, ganma enitters, and Sr-S9 and Sr-90.
^leekly analyses for beta activity in air particulate filters revealed that the annual range of data fer each site follcwed a sin 11ar trend. The ranges rise steadily during the first cuarter of the year, until they reach a peak nidway in the second quarter; thereafter, they " tail eff" steadily and cen-sistently during the rest of the year. The cause of this trend in anbient radioactivity is the fallout frca the nid-Octcher,19c0 detenatien of the nuclear bomb by the Pecple's depublic of China. Similar trends have been observed following weapons testing in the past (13,16,17).
Monthly analyses for ganna enitters showed the' presence of the fission by-products Ub-95, Zr-95, du-103, Ruah-1c6, Ce-lbl, and Ce-lih, predeninating the results for the first three cuarters of the year. The data ranges fer mest of these by-prcducts displayed the sane trend as the data ranges fer 7
January 1 - recember 31, 1961 Eceket Ecs. 5C-317/31S - beta activity discussed above, and these fission products are typical of tne radionuclides observed in previcus falleut patterns (15,16,17). Thus they are nost probably attributable to the mid-Ceteber detonatien. In addition to these typical falicus ractenuclides, Mn-5h and Cs-137 were c'eserved sporadically at the centrol locatien 23 and varicus indicater 1ccaticns surrounding the plant. In nest cases these two nuclides were observed mid-way in the secend quarter, at the sane time that the highest concentratiens of the typical fallout nuclides were cbserved. Though both En-5h and Cs-137 can be related to plant discharges, their sudden appearance at the peak cf the fallcut patterns and the fact that they were cbserved at centrol and indicator 1ccations far rencved fren each other, suggest that they also nay in fact be associated uith the benb detenated in nid-October. Quarterly radiostrentium analyses yielded data for Sr-69 and Sr-90, exhibiting trends similar to the data trends for beta and ganna activities in air partic-ulates as discussed in the preceding paragraphs. retectable cencentrations of both Sr-69 and Sr-90 were c'e served predeninately in the first and second quarters of the year at all locaticns. Luring the later part of the year the concentrations of both of these isotopes dirinished steadily to levels below the detectable linits. These trends in radiostrontium data are typical of what has been observed in previcus years (15,16,17) folicwing nuclear weapons testing, and they are censistent with the general fallcut patterns of cther radienuclides.. Thus, the detectacle concentratiens of both Sr-c9 and Sr-90 are nest probably related te the nid-Cetcher detonation. . 0.2.b Air Icdine Weekly cenpesite radiciccine sanples were ecliected fren five 1ccations; Cn Site (lecation 17), Cn Site (locatien 13), Lusby (lecatien 20), Ccve Point (lecation 22), and Taylers Island (lecatien 23). Radicicdine analyses perferred on the sanples fren all iccations exhibited no detectable concentra-tiens of 1-131. D.2.c Frecicitation Monthly composite precipitatien samples were collected fren ene site, On Site (location IS), and were analyzed for gress beta, H-3, ganna enitters, and St-89 and 'Sr-90. Menthly analyses fer beta activity in precipitation.sanples revealed that the annual range of data for this location follcwec ~the sane trend as that displayed by the beta and ganna data for air particulate filters, and thus nest probably also have the fallout fre t the recent Chinese weapons testing - as their source. Quarterly analyses for H-3 in cenposites of these sanples revealed a detectable concentration of 12S*113 pC1/1 in the third quarter conposite sanple. Though
.aEain it is pessible to attribute this radionuclide to plant discharges, it uis also pessible, appearing as it does in the same ' tine frane as the general fallcut pattern diccussed above, to asecciate it with nuclear weapons testing.
M
Janutry 1 - Eecember 31, 1961 Dcchet 1:cs. 5C-317/313 Monthly analyses for genna enitters ence again displayed the cresence of the typical fallcut fission by-precucts ::b-95, Zr-95, and Ru-iC3. These by ,creducts were spcradically cbserved in the first two quarters cf the year, very much in keeping with the general fallcut patterns as ciscussed previcusly. Quarterly results of radiostrentiun analyses of precipitation sanples seen to fall into the sane general fallcut patterns of nest of the atnespheric samples, previcusly discussed. retectable cencentrations of 3r-89 and Sr-90 were observed in the first two quarters of the year, and less than detectable cencentratiens predeninated the last two quarters. As ncted
. previcusly, this trend in results is typically expected after a recent nuclear benb test.
D.3 Terrestrial Snvirennent The terrestrial envircnnent was nonitored by analyzing sanples of vegetaticn, soil, and well water. These samples were collected fren varicus sanpling 1ccations near the plant. D.3.a Vegetation Vegetatien sanples 1:ere collected frca three 1ccations; Cn Site (lecation 1h), a nearby farn (locatien 15), and another nearby farn (lecatien 16). ' These sanples included cern, hay, tebacco, and wheat. They were analyzed for ganna enitters and Sr-89 and Sr-90. Analyses fer canna emitters revea' led the cresence cf Lb-95 and Ce-1LL in the August tcbacco sanple frca 1ccatien lh and .b-95, Cs-137, and Ce-lLL in the recember tobacco sanples fren 1ccatien 16. As previcuely discussed, these radienuclides are nest probably the result of past nuclear benb " testing. Radiostrentiux analyses of tnese sanples shcwed fcur detectable concentrations of Sr-59 (viz.,10:10 pC1/kg in the Septenter corn sanple fren locatien ih,- 109tL5 pCi/k g in the recenber hay sanple fren locatien 16, 356t330 pCi/kg in the recenter tobacco sanple fren 1ccation 16, and 6.2t7.8 pCi/kg in the Eecember silage sample fren locatien 15). It also shcued cetectable cencentra-tions of Sr-90, ranging fren 13th to 205012C0 pCi/kg, in nest of the sanples analyzed. The positive Sr-59 values can be related to either plant operatien er to fallcut fren malear weapcts testing. It shculd be noted thet the errors asscciated with nest of these values are relatively high, inplying that these values border the ninir un detectable linits of the Sr-d9 analysis. The Sr-90 re ults, en the other cand, seen to fall within the sare genersi patterns observed in preceding years when nuclear weapens testing was conducted (15,16,17), and those results are nest probably attributable to fallcut frer this testing. E.3.b Soil Soil samples were taken seniannually fren three On' Site 1ccatiens; 11,12, and 13. .These sanples were analyzed fcr psnna eritters and Sr-67 and Sr-90.

January 1 - 2ecenber 31, 1961 Eceket Ucs. 5C-317/315 . Analyses for canna enitters in these samples revealed tne presence of Ub-95, Zr-95, Ru-lO3, Cs-137, Ce-lhi, and Ce-1kh in the first seriannual sampling period, while the presence of Eb-95, Cs-137, and Ce-lkh predoninated in the second semiannual pericd. All of these radienuclides are nest probably due to the continuous depositien of fallout frem the mid-Cetcher,1960 nuclear weapons testing conducted by the Feeple's .iepublic cf China. Radiestrentiun analyses of these sanples shewed no detectable ccncentratiens of Sr-89 The analyses did show the presence cf Sr-90 in all the samples analyced. The results for Sr-90 raa.ged fren 3ht26 pCi/kg to 191th3 pCi/kg. This range of values is sinilar to these observed in the precperatienal (6) ar.d previcus cperaticnal (17) perices. D.3.c Well Water

and White Sands Club (locatiens 25A and 253). These samples were analyzed for H-3 and ganna emitters. With the exce tion of the June sanele fren locatien 253 wnich centained Ce-lbl, bcth the cuarterly analyses' for tritiun and ganna enitters in these sanples revealed that .o detectable cencentrations of fission er activatien by-products were present. The presence of Ce-lli is ecst pro'cably due to fallout fren recent nuclear weapcns testing and night be the result of fallout - conta:.inating the sample during its ecllecticn er its analysis. D.h External Radiatien ' Monthly therncluninescent dosineters vere taken fren 13 locatiens surrcunding the plant, namely; Plant Cutfall (lecation 7), On Site (lecatien 17), On Site (lecation 18), Knotty Fine (lecatien 19), Lusby (lecaticn 20), Leng Beach (lecation 21), Ccve Fcint (locatien 22), Taylors Island (location 23), On Site (locatien 2h), dhite Sands Club Sign (lecatien 25), St. Lecnard (lecation 26), Scicnens Island (locatien 27), and Zertha Church (location 26). The dosineters were read for external radiation dose rates in nR. The TLD data for each site are cenpiled in Table 3-13 and are presented en an annual basis in Table 2. The neans and ranges expressed in Table 2 were cenpared with the means and ranges for the previcus years cf 1976, 1979, and 1980. This ccmparison revealed that the means and ranges fer 1961 were sini-lar to these_cbserved in the three preceding years. E. Conclusien Eetectable concentratiens of radiericlides were cecasicnally o'eserved in samples frcn varicus locatiens during the year. The najority of these cbservations are sttributable to the fallcut fren atmoscheric nuclear weaumns testing conducted in October 1980 and in previcus years'. Ecuever, a fewc'i these'cbservatiens nay be directly related to the operation cf tne picnt 10 L:
January 1 - Seesnbar 31, 1931 Eceket Ecs. $C-317/313 (e .g., H-3, Co-30, and Sr-59 in bay water; Cc-36, 2n-63, and Ag-11Cn in oysters; Sr-89 in fish bones; Co-35 and Cc-60 in sedinent; ::n-5h, Sr-69, and Cs-137 in air filters; H-3 and Sr-89 in precipitatien; and Sr-89 in vegetation).-'In all cases, the concentraticns observed are icw and, conse-quently, would have very little radiolegical inpact en the surrcunding . envircreent. In order to assess the plant's actual contributien to the ar.bient radiatien levels of the surrcunding environnent, dose calculatiens were perfor ed using the plent's effluent release data, en site netecrological data, and apprcpriate pathways. The results of these dose calculations indicate:
- a. a naximum thyroid dese (via applicable pathways) cf 0.10 nren at location 16, which is less than C.25 of the acceptable lirit of 75 nren/ year as specified in h0 CFR 190 Envircreental Radiation Protection Standards for Nuclear Pcwer Operations;
- b. a narinun whole bcdy ganna dose of C.CO2 nren at location 23, which is less than 0.C1% of the acceptable dose of 25 nren/ year (h0 CIR 190); ,
- c. a maxi:=m whole bcdy dese (via all licuid pathways) of G.C6 nren, which is less than C.5% of the acceptable li .it cf 25 nrem/ year (ho CFP. 190).
Thus it is concluded, based upon tne levels of radioactinty observed and - the varicus dese calculations perferned, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1981 did not cause any significant changes in the radionuclide inventcry of the surrounding envircrrent or in the anbient radiation levels of critical pathways. 4 O 11 y
