SUMMARY
During the 2000 operating period for Calvert Cliffs Nuclear Power Plant (CCNPP) Units 1 and 2, radiochemical analyses were performed on environmental samples, and thermoluminescent dosimeters (TLDs) were analyzed for ambient radiation exposure rates. These analyses were performed to satisfy the requirements of the CCNPP Off-Site Dose Calculation Manual (ODCM), Sections 3/4.12 (6).
For the Independent Spent Fuel Storage Installation (ISFSI), radiochemical analyses were performed on environmental samples, some of which were in common with the power plant program. Additional TLDs, some of which are also in common with the power plant program, were analyzed for ambient radiation exposure rates. These analyses were performed to satisfy the requirements of the ODCM.
In addition, radiochemical analyses were performed on quality assurance samples as part of an internal and external quality assurance program associated with Teledyne Brown Engineering, Environmental Services. Performance evaluation samples obtained from the Analytics' Inc.
Cross-Check Program were also analyzed.
And lastly, analyses were performed on extra environmental samples, and extra TLDs were analyzed for ambient radiation exposure rates. Also, six pressurized ion chambers continuously monitored the environs around the plant for ambient radiation levels. The additional analyses reflect a commitment to maintain historical continuity for samples and sampling pathways discontinued from the program when the Environmental Technical Specifications were changed in March 1985 and to satisfy our commitment to the community.
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 radionuclides.
Monitoring the atmospheric environment involved sampling the air at various locations sur rounding CCNPP and the ISFSI. Air particulates and gaseous iodine were collected on glass fiber filters and silver zeolite molecular sieve cartridges, respectively. The particulate filters were analyzed for beta activity and gamma emitting nuclides. The molecular sieve cartridges were analyzed for airborne gaseous radioiodine.
Samples from the terrestrial environment consisted of vegetation and soil samples, collected and analyzed for gamma emitters. Vegetation samples for the CCNPP REMP were also analyzed for 1-131.
Measurements of direct radiation, as required by the ODCM, were performed by analyzing TLDs from forty locations surrounding CCNPP and the ISFSI.
I
January 1 - December 31, 2000 Docket Nos. 50-317/318 Low levels of various man-made fission were observed in the environment surrounding the plant during 2000. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plant (e.g., H-3 in quarterly composited bay water samples and Ag- 11Gm in oyster samples).
To assess the plant's contribution to the radiation levels of the ambient 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 indicate:
- a. a maximum thyroid dose of 1.81 x 10-2 mrem via liquid and gaseous pathways, which is about 0.02% of the acceptable limit of 75 mrem/yr as specified in 40 CFR 190;
- b. a maximum whole body dose of 1.79 x 10.2 mrem via liquid and gaseous pathways, which is < 0.1% of the acceptable limit of 25 mrem/yr as specified in 40 CFR 190;
- c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 2.11 x 10' mrem to the GI-Tract. This dose was <1% of the allowable limit of 25 mrem/yr as specified in 40 CFR 190.
Thus, it is concluded based upon the levels of radioactivity observed and the various dose calculations performed, that Calvert Cliffs Nuclear Power Plant Units 1 and 2 and the ISFSI did not cause any significant radiological impact on the surrounding environment during 2000.

January 1 - December 31, 2000 Docket Nos. 50-317/318 II. CALVERT CLIFFS NUCLEAR POWER PLANT RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM II.A. INTRODUCTION Constellation Energy Group (CEG), previously known as Baltimore Gas and Electric Company, has been conducting a radiological environmental monitoring program 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 (REMP) was conducted under separate Environmental Technical Specifications (1, 2). On July 29, 1977 the monitoring program began operation under a combined set of Technical Specifications (3) for both Units.
The program has operated as such until March 1, 1985 when the Environmental Technical Specifications were revised to reflect a new generic format for radiological environmental monitoring adopted by the Nuclear Regulatory Commission (4). Changes in the program (sample locations, sample types, and/or sampling frequencies) were implemented to conform to these revisions. In October 1996, the Nuclear Regulatory Commission approved the relocation of these Technical Specifications to the ODCM in accordance with Generic Letter 89-01. (5)
Results of the monitoring program for the pre-operational and previous operational periods through December 31, 1997 have been reported in a series of documents (16-5 1).
Results of the monitoring program for the current operational period of January 1, 2000 through December 31, 2000 are included in this report. The report presents the content of the Radiological Environmental Monitoring Program (Table 1), the sampling locations (Appendix A), the summary of the analytical results of 2000 (Table 2), a compilation of the analytical data for 2000 (Appendix B), the results of the Analytics Intercomparison Program and the Quality Assurance Program (Appendix C), the results of the Land Use Census (Appendix D), and a compilation of the analytical data for extra samples collected in 2000 (Appendix E).
Interpretation of the data and conclusions are presented 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 to evaluate the environmental radiological impact of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 2000.
II.B. PROGRAM II.B.1 Objectives The objectives of the REMP for the Calvert Cliffs Nuclear Power Plant are:
3
January 1 - December 31, 2000 Docket Nos. 50-317/318
- a. To verify that radioactivity and ambient radiation levels attributable to plant operation are within the limits specified in the ODCM (6) and the Environmental Radiation Protection Standards as stated in 40 CFR Part 190,
- b. To detect any measurable buildup of long-lived radionuclides in the environment,
- c. To monitor and evaluate ambient radiation levels,
- d. To determine whether any statistically significant increase occurs in the con centration of radionuclides in important pathways.
II.B.2 Sample Collection The locations of the individual sampling stations are listed in Table A-i and shown in Figures A 2 and A-3. All samples were collected by contractors to, or personnel of, CEG according to Calvert Cliffs Nuclear Power Plant Procedures (7).
II.B.3 Data Interpretation Many results in environmental monitoring occur at or below the minimum detectable activity (MDA). In this report, all results at or below the relevant MDA are reported as being "less than" the MDA value.
II.B.4 Program Exceptions For the period 1998 through 2000, oysters have not been available at Kenwood Beach (1a6) which is the designated control (background) location. During this time control samples were obtained from an alternate location at Hog Island (Ial 0). In addition to the challenges encountered at Kenwood Beach, the amount of oysters available at the plant site location, Camp Conoy (1a3), was greatly diminished in 1999 and 2000. Due to these ongoing problems with oyster collection, special sampling platforms were deployed in 2000. This approach should ensure that the population of oysters will be adequate to support the REMP.
II.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using Constellation Power Source Generation (CPSG) laboratory procedures (8). The analytical results for this reporting period are presented in Appendix B and are also summarized in Table 2. For discussion, the analytical results are divided into four categories. The categories are the Aquatic Environment, the Atmospheric Environment, the Terrestrial Environment, and Direct Radiation.
These categories are further divided into subcategories according to sample type (e.g., Bay Water, Aquatic Organisms, etc., for the Aquatic Environment).
4
January 1 - December 31, 2000 Docket Nos. 50-317/318 II.C.1 Aquatic 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.
II.C.l.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 the presence of tritium in the Discharge (Wa2) samples in each of the four quarters, while detectable readings were observed in the Intake (Wal) in three of the four quarters. It is not unusual to observe occasional tritium in the Intake as a result of bay water recirculation. The concentrations observed in the discharge ranged from 78+/-36 to 791+/-45 pCi/L and the results in the intake ranged from <MDA to 68+/-37 pCi/L, which are similar to those ranges observed in previous years, (22-51).
Figure 1 compares tritium observed in the plant discharge and intake with annual effluent releases in 2000 as reported in the Radioactive Effluent Release Report.
Monthly analyses of bay water samples from both locations for gamma emitters exhibited no detectable concentrations of any plant-related radionuclides.
II.C. 1.b Aquatic Organisms Samples of aquatic organisms were obtained from four locations during the year. Samples of fish, when in season, are normally collected from the Intake-Discharge Area (sample codes Ial and Ia2) and from the Patuxent River (sample codes Ia4 and Wa5). As shown in Table B-2, two species of fish were sampled at both the plant intake and the control point in the Patuxent River.
Oyster samples were obtained quarterly from Camp Conoy (sample code 1a3), Hog Island (sample code Ial 0), and Kenwood Beach (sample code Ia6) when available. The Hog Island site was utilized as a control location in lieu of Kenwood Beach when samples were unavailable there. In addition, samples of non-commercial mussels were also taken from Camp Conoy when samples of oysters were unavailable there. (Previous studies suggest that mussels may be the biological analogue of oysters when it comes to the uptake of Ag- I10m.) Edible portions of the fish, oyster and mussel samples were analyzed for gamma emitters.
5
January 1 - December 31, 2000 Docket Nos. 50-317/318 Gamma spectrometric analyses of the fish exhibited no detectable concentrations of any plant related radionuclides. Oyster and mussel samples exhibited low levels of detectable concentrations of the plant-related radionuclide, Ag-I1 Om, in samples obtained from Camp Conoy (Ia3). These concentrations, which ranged from 29+/-21 to 195+/-17 pCi/kg, are consistent with that expected due to liquid effluents from the plant during the year 2000. Three of the five quarterly oyster samples taken from Hog Island (Ial 0) and Kenwood Beach (Ia6) also exhibited low levels of Ag-i 10m. These concentrations, which ranged from 8+/-6 to 21+/-9 pCi/kg, are very close to the typical LLD for Ag-11 Om as reported in Table B-11.
II.C.l.c Shoreline Sediment Semiannual shoreline sediment samples were taken from one location during the year. This location is Shoreline at Barge Road (sample code Wbl). The samples obtained from this location were analyzed for gamma emitters.
Gamma spectrometric analyses of these samples exhibited no detectable concentrations of any plant-related radionuclides.

January 1 - December 31, 2000 Docket Nos. 50-317/318 II.C.2 Atmospheric Environment The atmospheric environment was monitored by analyzing air particulate filters and silver zeolite cartridges (for trapping radioiodine species). These samples were collected from five locations surrounding the plant. These locations are On Site before the Entrance to Camp Conoy (sample code Al), Camp Conoy Road at the Emergency Siren (sample code A2), Bay Breeze Road (sample code A3), Route 765 at Lusby (sample code A4), and at the Emergency Operations Facility (sample code A5).
II.C.2.a Air Particulate Filters Weekly composite air particulate filter samples were collected from the five locations during the year. These samples were analyzed for beta activity and gamma emitters.
Weekly analyses for beta activity on air particulate filters collected from all five locations 2
showed values characteristic of background levels (7-35). The values ranged from 0.3xl0- to 3.9x10" 2 pCi/m 3 for the indicator locations and 0.4x10 -2 to 3.8x10 -2 pCi/m 3 at the control lo cation. The location with the highest overall mean of 1.7x10 -2 pCi/m 3 was Al, Entrance to Camp Conoy.
Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples.
Figure 3 depicts the historical trends of beta activity.
II.C.2.b Air Iodine Weekly composited silver zeolite cartridges (for trapping radioiodine species) were collected from the five locations during the year. These samples were analyzed for radioiodine species.
Weekly radioiodine analyses of silver zeolite cartridges collected from all five locations ex hibited no detectable concentrations of 1-131.
Figure 3 depicts the historical trends of radioiodine.
II.C.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation collected monthly, when available, from various sampling locations near the plant during the normal growing season.

January 1 - December 31, 2000 Docket Nos. 50-317/318 II.C.3.a Vegetation Vegetation samples were collected from three locations during the year. These locations are Garden Plot off Bay Breeze Road (sample codes IbI, Ib2, and Ib3), On Site before the Entrance to Camp Conoy (sample codes Ib4, Ib5, and Ib6), and the Emergency Operations Facility (sample codes Ib7, Ib8, and Ib9). These samples were analyzed for gamma emitters, including analyses for 1-131.
Gamma spectrometric analyses exhibited no detectable concentrations of plant-related radionuclides in any of these samples.
II.C.4 Direct Radiation Direct radiation is measured by a network of TLDs in each overland sector surrounding the Plant both at the plant boundary and at 4 miles from the Plant.
Thermoluminescent dosimeters were collected quarterly from twenty-three locations surrounding the plant. The twenty indicator locations are On Site Along the Cliffs (sample code DR1), Route 765 Auto Dump (sample code DR2), Giovanni's Tavern (sample code DR3), Route 765 across from White Sands (sample code DR4), John's Creek (sample code DR5), Lusby (sample code DR6), On Site before the Entrance to Camp Conoy (sample code DR7), On Site at Emergency Siren (sample code DR8), Bay Breeze Road (sample code DR9), Decatur and Calvert Beach Roads (sample code DR10), Dirt Road off Mackall and Parran Roads (sample code DRI 1),
Mackall and Bowen Roads (sample code DR12), Wallville (sample code DR13), Rodney Point (sample code DR14), Mill Bridge and Turner Roads (sample code DRI5), Appeal School (sample code DR16), Cove Point and Little Cove Point Roads (sample code DR17), Cove Point (sample code DR1 8), Long Beach (sample code DRI 9), and On Site Near Shore (sample code DR20). The three control locations are the Emergency Operations Facility (sample code DR2 1),
Solomons Island (sample code DR22), and Taylors Island, Carpenters Property (sample code DR23).
The mean 90 day ambient radiation measured at the indicator locations was 10.44 mR and ranged from 7.97 to 13.75 mR as reported in Table 2. The control locations showed a 90 day mean of 12.29 mR with ranges from 10.04 to 14.70 mR. The location with the highest overall mean of 14.12 was DR23, Taylors Island, Carpenters Property, which ranged from 13.49 to 14.70 mR. A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data (22-51) shows no plant-related contribution to the measured direct radiation exposure for 2000. Figure 4 shows the historical comparison of the average monthly radiation levels per calendar year for TLDs on site, at four miles, and at the control locations.

January 1 - December 31, 2000 Docket Nos. 50-317/318 II.D. CONCLUSION Low levels of man-made fission by-products were observed in the environment surrounding the plant during 2000. These by-products were related to the operation of the plant (e.g., tritium in quarterly composited bay water samples and Ag- 110m in oysters and mussels).
Historical trends for tritium in bay water, Ag- 11 Gm and K-40 in oyster samples, nuclear fallout in the Calvert Cliffs area, and TLD data are depicted in Figures 1 through 4. As can be seen from these figures, the plant.made no adverse radiological contributions to the surrounding environment during 2000.
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 (see X/Q and D/Q values presented in Figures 5 and 6), and appropriate pathways. The results of these dose calculations indicate:
Gaseous Pathways A maximum thyroid dose of 5.05 x 10-) mrem to a child via the plume, ground, vegetable, meat, and inhalation pathways at 2.6 km SW of the containments Calvert Cliffs. This is < 0.01% of the acceptable limit of 75 mrem/year as speci fied in 40 CFR 190, "Environmental Radiation Protection Standards for Nuclear Power Operations."
A maximum whole body gamma dose of 2.38 x 10- 4 mrem to a child at 2.1 km SE of the containments at Calvert Cliffs, which is < 0.0 1% of the acceptable dose limit of 25 mrem/year as specified in 40 CFR 190.
A maximum dose to any other organ, in this case the skin, of 1.90 x 10-3 mrem at 2.1 km SE of the containments at Calvert Cliffs. This is <0.01% of the acceptable dose limit of 25 mrem/year as specified in 40 CFR 190.
Liquid Pathways A maximum thyroid dose of 1.30 x 10-2 mrem to an adult for all liquid pathways, which is about 0.02% of the acceptable dose limit of 75 mrem/year as specified in 40 CFR 190.
A maximum whole body dose of 1.77 x 10-2 mrem to an adult via all liquid pathways, which is <0.1% of the acceptable dose limit of 25 mrem/year as stated in 40 CFR 190.
13
January 1 - December 31, 2000 Docket Nos. 50-317/318 A maximum dose to any organ, in this case the GI-Tract, of 2.10 x 10-1 mrem to an adult for all pathways, which is <1% of the acceptable dose limit of 25 mrem/year specified in 40 CFR 190.
Gaseous and Liquid Pathways Combined A maximum thyroid dose of 1.81 x 10- 2 mrem via liquid and gaseous pathways, which is about 0.02% of the acceptable limit of 75 mrem/year specified in 40 CFR 190.
A maximum whole body dose of 1.79 xl 0-2 mrem via liquid and gaseous pathways which is < 0.1% of the acceptable limit of 25 mrem/year as specified in 40 CFR 190.
A maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 2.11 x10- 1 mrem to the GI-Tract. This dose is <1% of the allowable limit of 25 mrem/year as specified in 40 CFR 190.
In all cases, the calculated doses are a small fraction of the applicable limits specified in 40 CFR 190. Therefore, it is concluded that the operation of Calvert Cliffs Units 1 & 2 produced radioactivity and ambient radiation levels significantly below the limits of Off-Site Dose Calculation Manual and 40 CFR Part 190 and there was no significant buildup of radionuclides in the environment due to Calvert Cliffs.

January 1 - December 31, 2000 Docket Nos. 50-317/318 III. INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM III.A. INTRODUCTION In August 1990 BGE initiated a program of additional radiological environmental monitoring around the site for the Independent Spent Fuel Storage Facility (ISFSI). The first dry fuel storage canister was loaded into the ISFSI in November of 1993.
Results of the monitoring program for the ISFSI for the current period of January 1, 2000 through December 31, 2000 are included in this report.
This report presents the content of the ISFSI radiological environmental monitoring program (Table 3), the ISFSI sampling locations (Appendix A), the summary of the analytical results of the period (Table 4), and a compilation of the analytical data for the period (Appendix B). Inter pretation of the data and conclusions are presented in the body of the report.
The ISFSI monitoring program is as described in this section of the report with the exception of the Pressurized Ion Chambers (PICs). Pressurized Ion Chambers, because they duplicate direct surveillance by TLDs and because they experience problems with reliability, were excluded from the Technical Specification portion of the ISFSI REMP (9). Pressurized Ion Chambers' results, however, are given in table E-9 and will continue to be a non-ODCM surveillance to satisfy our commitment to the community.
The results for 2000 were compared with that generated during the previous ISFSI pre operational periods (10) and the current and previous CCNPP REMP periods (22-5 1). These comparisons demonstrate the consistency of data throughout the CCNPP site, which are very close to the natural background levels for the region. A discussion of these results is given in Section III.C.
III.B. PROGRAM III.B.1 Obiectives The objectives of the radiological environmental monitoring program for the ISFSI are:
- a. To satisfy the community concern regarding the impact of the ISFSI on the environment,
- b. To verify that radioactivity and ambient radiation levels attributable to operation of the ISFSI are within the limits specified in the Environmental Radiation Protection Standards as stated in 40 CFR Part 190,
- c. To detect any measurable buildup of long-lived radionuclides in the environment due to the ISFSI, 21
January 1 - December 31, 2000 Docket Nos. 50-317/3 18
- d. To monitor and evaluate ambient radiation levels around the ISFSI,
- e. To determine whether any statistically significant increase occurs in the con centration of radionuclides near the ISFSI.
III.B.2 Sample Collection The locations of the individual sampling sites are listed in Table A-2 and shown in Figures A-4 and A-5. All samples were collected by contractors to, or personnel of, CPSG personnel according to CPSG Procedures (8).
III.B.3 Data Interpretation Many results in environmental monitoring occur at or below the minimum detectable activity (MDA). In this report, all results at or below the relevant MDA are reported as being "less than" the MDA value.
III.B.4 Program Exceptions There were no program exceptions during 2000.
III.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using CPSG's laboratory procedures (8). The analytical results for this reporting period are presented in Appendix B and are also summarized for the period in Table 4. For discussion, the analytical results are divided into three categories. The categories are the Atmospheric Environment, the Terrestrial Environment, and Direct Radiation. These categories are further divided into subcategories according to sample type (e.g., Vegetation and Soil for Terrestrial Environment).
III.C. 1 Atmospheric Environment The atmospheric environment was monitored by analyzing air particulate filters. These samples were collected from five locations surrounding the ISFSI.
No source of airborne radioiodine exists for the ISFSI. Airborne radioiodine is, therefore, not considered.
III.C. l.a Air Particulate Filters Weekly composite air particulate filter samples were collected from five locations during the period. These locations are On Site before the Entrance to Camp Conoy (sample code Al; in common with the CCNPP REMP), Meteorological Station (SFA1), CCNPP Visitor's Center (SFA2), NNW of the ISFSI (SFA3), and South of the ISFSI (SFA4). These samples were an alyzed for beta radioactivity and gamma emitting radionuclides.
22
January 1 - December 31, 2000 Docket Nos. 50-317/318 Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic of levels routinely observed in the REMP (22-51). These values 2
ranged from 0.4x1 0-2 to 4.6x10- 2 pCi/m for the indicator locations and 0.4x10- to 3.4x10-2 3
pCi/m 3 for the control location. The location with the highest overall mean of 1.8x1 0-2 pCi/m3 was SFA4, South of ISFSI.
Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples.
III.C.2 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation and soil collected quarterly from the vicinity of the air sampling locations for the ISFSI.
III.C.2.a Vegetation Vegetation samples were collected quarterly from five locations during the year. These locations are: Meteorological Station (sample code SFbl), CCNPP Visitor's Center (sample code SFb2),
NNW of the ISFSI (sample code SFb3), South of the ISFSI (sample code SFb4), and On Site before the Entrance to Camp Conoy (sample code SFb5). These samples were analyzed for gamma emitters.
Gamma spectrometric analyses of these samples exhibited no detectable concentration of any plant-related radionuclides in any of these samples.
III.C.2.b Soils Soil samples were collected quarterly from five locations surrounding the ISFSI in the vicinity of the air samplers. These locations are: Meteorological Station (sample code SFS1), CCNPP Visitor's Center (sample code SFS2), NNW of the ISFSI (sample code SFS3), South of the ISFSI (sample code SFS4), and On Site before the Entrance to Camp Conoy (sample code SFS5).
Soil samples were analyzed for gamma emitting radionuclides. Cesium-137 was detected in twelve quarterly samples from both indicator and control locations. The Cs-137 concentrations ranged from 59+/-25 to 727+/-91 pCi/kg. While the presence of Cs-137 in these samples may be plant-related, this range is consistent with that found to be due to the residual fallout from past atmospheric nuclear weapons testing. The activities of this radionuclide are well below the federal limits established in 40 CFR 190, "Environmental Radiation Protection Standards for Nuclear Power Operations" and are comparable to those observed in previous annual reporting periods for the CCNPP REMP (22-51) and in the earlier pre-operational data for the ISFSI (10).
23
January 1 - December 31, 2000 Docket Nos. 50-317/318 III,C.3 Direct Radiation Direct radiation is measured by a network of TLDs surrounding the ISFSI. These thermo luminescent dosimeters are collected quarterly from seventeen locations surrounding the ISFSI, plus one control TLD location at the Visitor's Center (sample code SFDR7). The locations include On Site before the Entrance to Camp Conoy (sample code DR7, common to both the CCNPP Program and the ISFSI Program) and the Meteorological Station (sample code DR30, previously a location maintained for historical continuity.) The other sampling locations are:
SW of ISFSI (sample code SFDRI); N of ISFSI (sample code SFDR2); NNE of ISFSI, sample code SFDR3; NE of ISFSI (sample code SFDR4); E of ISFSI (sample code SFDR5); ESE of ISFSI (sample code SFDR6); North Northwest of ISFSI (sample code SFDR8); South of ISFSI (sample code SFDR9); NNW of ISFSI (sample code SFDR1O); WNW of ISFSI (sample code SFDR11); West of ISFSI (sample code SFDR12); SSW of ISFSI (sample code SFDR13); SSE of ISFSI (sample code SFDR14); ENE of ISFSI (sample code SFDR15); and WSW of ISFSI (sample code SFDR16). Sampling locations are shown on Figures A-4 and A-5.
The mean 90 day ambient radiation measured at the ISFSI indicator locations was 17.13 mR and ranged from 8.57 to 39.13 mR as reported in Table 4. The control location showed a 90 day mean of 11.61 mR and ranged from 10.78 to 12.32 mR. A comparison of the mean and ranges of the current TLD data with those of both the historical data and the regional data (22-51, 10) reveals only one set of elevated TLD readings. That location with the highest overall mean of 35.67 mR with a range of 30.10 to 39.13 mR was SFDR1O, North Northwest of ISFSI. These readings are consistent with those expected from the storage of spent fuel in the ISFSI (22-51, 10). A comparison of the average monthly radiation levels per calendar year of the ISFSI TLD data from the indicator locations with the ISFSI control location at the Visitor's Center, SFDR7, can be seen in Figure 7.
24
January 1 - December 31, 2000 Docket Nos. 50-317/318 IIL.D. CONCLUSION Low levels of Cs-137 were observed in the environment surrounding the ISFSI during the period.
The Cs- 137 observations were attributed to fallout from past atmospheric weapons testing.
In general, the results in the following tables continue the historical trends previously observed at the official sites of the Calvert Cliffs Nuclear Power Plant Radiological Environmental Monitoring Program (22-51).

January 1 - December 31, 2000 Docket Nos. 50-317/318 APPENDIX C Appendix C is a summary of CPSG Laboratory's quality assurance program. It consists of Table C-1 which is a compilation of the results of the Laboratory's participation in the Analytics Radiological Environmental Cross-Check Program during the period January 1, 2000 to December 31, 2000. It also consists of Table C-2 and Table C-3 that together form a compilation of the results of the Laboratory's participation in a quality assurance program with Teledyne Brown Engineering's Environmental Services during the same period. The Teledyne Brown Engineering operating procedures pertinent to these analyses are described in Reference (11).
All CPSG Laboratory's results contained in Table C-I agree with Analytics' results with the exception of five isotopes for the filter sample type on 6/22/00. Reanalysis of the filter did not result in agreement within the 3 sigma control limit, however, three of the five original results were in agreement when using the NRC Resolution Test Criteria'. The supplier was contacted to obtain the results of all participants in this cross check. Evaluation of all the data showed the presence of a systematic error and that the CPSG Laboratory data was consistent with other participants.
All the results contained in Table C-2 agree with the Laboratory replicates and split samples submitted to Teledyne Brown Engineering, where appropriate. Samples whose nature precludes splitting them with Teledyne Brown Engineering are marked ""** in the Split Analysis column.
Although the CPSG Laboratory participated in the 12 t" International Intercomparison of Environmental Dosimeters, the results were unavailable at the time of this report. The results will be included in next year's report.

January 1 - December 3 1, 2000 Docket Nos. 50-317/318 APPENDIX D Appendix D contains the results of a Land Use Census conducted around Calvert Cliffs Nuclear Power Plant during August 2000. A table listing the raw data of this census and a discussion of the results are included in this appendix.
Discussion Table D-1 Land Use Census A Land Use Census was conducted during August 2000 to identify, within a distance of 8 Plant Distance From kin, the location of the nearest milk animal, the (kn) nearest residence, and the nearest garden greater Sector Residence Garden than 50 m 2 in each of the nine sectors over land.
SE 2.7 2.7 A detailed description of the Land Use Census is SSE 2.9 2.9 given in a separate document (12). The position S 3.1 3.1 of the nearest residence and garden in each sector SSW 2.6 2.9 out to 8 km are given in the adjacent table. No SW 2.1 2.6 dairy animal was found within 8 km in any WSW 1.9 1.9 direction. There has not been any significant W 2.1 2.4 change in the use of local lands in the last few WVNW 2.6 2.6 years.
NW 2.9 2.9 The closest residence and garden are situated in the WSW sector, which is one of the least prevalent wind directions. In the S, SSE, and SE sectors, there is the highest probability of wind blowing from the direction of the plant. The two gardens used for vegetable samples by the Radiological Environmental Monitoring Program have been placed in the sectors with the highest D/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 radioactive depositions around the plant.
The dose assessment using 2000 meteorological data was performed, and no significant impact from the plant was found.

January 1 - December 31, 2000 Docket Nos. 50-317/318 APPENDIX E Appendix E is a presentation of the analytical results for additional samples collected in the environs of Calvert Cliffs Nuclear Power Plant during the year 2000. These extra samples are not required by the Off Site Dose Calculation Manual (6). They were collected and analyzed to maintain the historical continuity for samples and sampling pathways discontinued when the Environmental Technical Specifications were changed in March, 1985. Additionally, they include the Pressurized Ion Chambers added for the Independent Spent Fuel Storage Installation.
Table E-9 shows the average monthly direct radiation as measured by the pressurized ion chamber at five locations.
Table E-Il shows the direct radiation readings from TLDs placed at the perimeter of the interim resin storage area located to the west of the ISFSI facility. This storage area is located inside the owner controlled area. Public access to this area is limited. The TLD values are higher than those in the REMP program due to their proximity to the source of the radiation. However, when the direct radiation readings for the ISFSI and Site Boundary TLDs are reviewed, it is apparent that storage of the spent resin is having no significant, measurable effect on the environs surrounding Calvert Cliffs Nuclear Power Plant.
