SUMMARY

During this operating period for Calvert Cliffs Nuclear Power Plant (CCNPP) Units 1 and 2, a total of 3391 radiological analyses were performed and the analytical results reviewed. Most of these analyses were performed to satisfy the requirements of the Offsite Dose Calculation Manual (ODCM) (Ref. 2) and the Environmental and Independent Spent Fuel Storage Installation (ISFSI) Technical Specifications (Ref. 1, 6). Some of these samples, although not required by either the ODCM or the Technical Specifications, were collected to maintain our commitments to the surrounding community and to maintain historical continuity of the CCNPP Radiological Environmental Monitoring Program (REMP) that started in 1970. The entire monitoring program in place around CCNPP is divided into three parts: the original REMP, the ISFSI monitoring program, and the Non-ODCM Radiological Environmental Monitoring. The following paragraphs describe each of these parts in more detail.

A total of 652 radiochemical analyses were performed on 584 environmental samples, and 546 thermoluminescent dosimeters (TLDs) were analyzed for ambient radiation exposure rates as part of the original REMP. These analyses were performed to satisfy the requirements of the ODCM (Ref. 2) and the Environmental Technical Specifications (Ref. 1).

For the ISFSI monitoring program, 355 radiochemical analyses were performed on 295 environmental samples, 49 of which were in common with the original REMP. In addition, 438 TLDs, 24 in common with the original REMP, were analyzed for ambient radiation exposure rates. These analyses were performed to satisfy the requirements of the ODCM (Ref. 2) and the ISFSI Technical Specifications (Ref. 6).

In addition, 584 analyses were performed on 536 additional environmental samples, and 474 additional TLDs were analyzed for ambient radiation exposure rates. Also, six pressurized ion chambers continuously monitored the environs around the plant for ambient radiation levels resulting in 72 monthly measurements. As mentioned earlier, these 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 monitoring commitments made to the surrounding community.

And lastly, 204 radiochemical analyses were performed on 188 quality assurance samples and 66 quality assurance TLDs were analyzed as part of an internal and external quality assurance program associated with Teledyne Brown Engineering. Laboratory intercomparison samples obtained from Environmental Resource Associates (ERA) and Analytics' Inc. were also analyzed.

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 I

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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 original REMP were also analyzed for I-131.

Measurements of direct radiation, as required by the ODCM, were performed by analyzing TLDs from forty locations surrounding CCNPP and the ISFSI.

Natural radioactivity was detected in essentially all 3391 radiological analyses performed. Low levels of various man-made fission and activation products were also observed in 34 of these analyses. Twenty-nine of these observations were attributed to fallout from past atmospheric weapons testing, while five analyses yielded low level positive results for the presence of H-3, which were attributable to plant operation. Detailed discussions about the results of these analyses are contained in the body of this report.

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 5.84 x 10-3 mrem via liquid and gaseous pathways, which is less than 0.01% of the acceptable limit of 75 mrem/yr as specified in 40 CFR Part 190;

b. a maximum whole body dose of 4.19 x 10-3 mrem via liquid and gaseous pathways, which is less than 0.02% of the acceptable limit of 25 mremlyr as specified in 40 CFR Part 190;

c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 2.26 x 10-2 mrem to the GI-Tract. This dose is less than 0.1 % of the allowable limit of 25 mrem/yr as specified in 40 CFR Part 190.

Thus, it is concluded based upon the levels of radioactivity observed and the various dose calculations performed, that CCNPP Units 1 and 2 and the ISFSI did not cause any significant radiological impact on the surrounding environment.

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 II. CALVERT CLIFFS NUCLEAR POWER PLANT RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM II.A. INTRODUCTION Constellation Energy (CE), previously known as Baltimore Gas and Electric Company (BGE),

has been conducting a REMP in the environs of the CCNPP 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. The location of the plant in relation to local metropolitan areas is shown on Figure A-1, page 38.

Results of the monitoring program for the pre-operational and previous operational periods through December 31, 2002 have been reported as required.

Results of the monitoring program for the current operational period are included in this report.

The report presents the content of the REMP (Table 1), the sampling locations (Appendix A), the summary of the analytical results (Table 2), a compilation of the analytical data (Appendix B),

the results of the Analytics 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 (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 CCNPP Units I and 2.

II.B. PROGRAM ll.B.1 Objectives The objectives of the REMP for the Calvert Cliffs Nuclear Power Plant are:

a. To verify that radioactivity and ambient radiation levels attributable to plant operation are within the limits specified in the ODCM (Ref. 2) 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.

January I - December 31, 2003 Docket Nos. 50-317/50-318/72-8 ll.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 Constellation Energy according to CCNPP Procedures (Ref. 3).

ll.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.

ll.B.4 Pro2ram Exceptions There were no program exceptions for this operating period.

II.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using Constellation Energy laboratory procedures (Ref. 4). 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).

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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.

IIC..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 all four quarters and in the Intake (Wal) in only one of the four quarters. It is not unusual to observe concentrations of tritium occasionally in the Intake as a result of bay water recirculation. The detectable concentrations observed in the Discharge ranged from 207 +/-41 to 767 +/-44 pCi/L, and in the Intake ranged from less then detectable to 53 +39 pCi/L which are similar to those ranges observed in previous years.

Figure 1 compares tritium observed in the plant discharge and intake with annual effluent releases 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.

ll.C.L.b Aquatic Organisms Six samples of aquatic organisms were obtained from four locations during the year. Samples of fish, when in season, are normally collected from the Discharge Area (sample codes Ial and Ia2) and from the Patuxent River (sample codes Ia4 and LaS). As shown in Table B-2, two species of fish were sampled at both the plant discharge and the control point in the Patuxent River. Oyster samples were obtained quarterly from Camp Conoy (sample code 1a3) and Kenwood Beach (la6).

Edible portion of the fish and oyster samples were analyzed for gamma emitters.

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 Gamma spectrometric analyses of the fish exhibited naturally occurring K-40, but no detectable concentrations of any plant-related radionuclides. Oyster samples likewise exhibited naturally occurring K-40, but no detectable concentrations of any plant related radionuclides.

ll.C. 1 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 naturally occurring radionuclides, but no detectable concentration of any plant-related radionuclides.

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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 AS).

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 showed values characteristic of background levels. The values ranged from 0.2 x 10-2 to 3.0 x 10-2 pCi/m3 for the indicator locations and 0.5 x 10-2 to 2.2 x 10-2 pCi/m3 at the control lo-cation. The location with the highest overall mean of 1.7x10-2 pCi/m3 was A4, Route 765 at Lusby.

Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples. Naturally occurring radionuclides, such as Be-7, were detected in nearly all 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 I-13 1.

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, 2003 Docket Nos. 50-317/50-318/72-8 II.C.3.a Vegetation Nine vegetation samples were collected from three locations during the year. These locations are Garden Plot off 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 Operations Facility (sample codes Ib7, Ib8, and 1b9). These samples were analyzed for gamma emitters, including analyses for I-131.

All samples showed detectable amounts of naturally occurring K-40 and Be-7. No plant related radionuclides were found in any of these samples.

11.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.

TLDs were collected quarterly from twenty-three locations surrounding the plant. The twenty indicator locations are On Site Along the Cliffs (sample code DRI), 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 DR1O), Dirt Road off Mackall and Parran Roads (sample code DRI 1), Mackall and Bowen Roads (sample code DR12), Wallville (sample code DRI 3), Rodney 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 DRI 7), Cove Point (sample code DRI 8), Long Beach (sample code DRI9), 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 12.02 mR and ranged from 9.38 to 16.01 mR as reported in Table 2. The control locations showed a 90 day mean of 13.39 mR with ranges from 9.95 to 17.15 mR. The location with the highest overall mean of 15.96 was DR23, Taylors Island, Carpenters Property, which ranged from 14.49 to 17.15 mR. A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data shows no plant-related contribution to the measured direct radiation exposure. 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, 2003 Docket Nos. 50-317/50-318/72-8 ILD. CONCLUSION Low levels of two man-made fission products were observed in the environment surrounding the plant, i.e. Cs-137 and tritium. The Cs-137 observations were attributed to fallout from past atmospheric weapons testing. Tritium was related to the operation of the plant (e.g., tritium in quarterly composited bay water samples).

Historical trends for tritium in bay water, Ag-I 10m and K-40 in oyster samples, background activity 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.

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 4.84 x 10-3 mrem to a child via the plume, ground, vegetable, meat, and inhalation pathways at 1.7 km SW of Calvert Cliffs. This is less than 0.01% of the acceptable limit of 75 mrem/yr as specified in 40 CFR Part 190, "Environmental Radiation Protection Standards for Nuclear Power Operations."

A maximum whole body gamma dose of 2.35 x 10-3 mrem to a child at 1.7 km SW of Calvert Cliffs, which is less than 0.01% of the acceptable dose limit of 25 mrem/yr as specified in 40 CFR Part 190.

A maximum dose to any other organ, in this case the skin, of 2.84 x 10-3 mrem to all age groups at 1.7 km SW of Calvert Cliffs. This is about 0.01% of the acceptable dose limit of 25 mrem/yr as specified in 40 CFR Part 190.

Liquid Pathways A maximum thyroid dose of 1.00 x 10-3 mrem to an adult for all liquid pathways, which is about 0.00 1% of the acceptable dose limit of 75 mrem/yr as specified in 40 CFR Part 190.

A maximum whole body dose of 1.84 x 10-3 mrem to a child via all liquid pathways, which is less than 0.01% of the acceptable dose limit of 25 mrem/yr as stated in 40 CFR Part 190.

13

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 A maximum dose to any organ, in this case the GI-Tract, of 2.26 x 10-2 mR to an adult for all pathways, which is less than 0.1% of the acceptable dose limit of 25 mrem/yr specified in 40 CFR Part 190.

Gaseous and Liquid Pathways Combined A maximum thyroid dose of 5.84 x 10-3 mrem via liquid and gaseous pathways, which is less than 0.01% of the acceptable limit of 75 mrem/yr as specified in 40 CFR Part 190; A maximum whole body dose of 4.19 x 10-3 mrem via liquid and gaseous pathways, which is less than 0.02% of the acceptable limit of 25 mrem/yr as specified in 40 CFR Part 190; A maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 2.26 x 10-2 mrem to the GI-Tract. This dose is less than 0.1% of the allowable limit of 25 mrem/yr as specified in 40 CFR Part 190.

In all cases, the calculated doses are a small fraction of the applicable limits specified in 40 CFR Part 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 the ODCM and 40 CFR Part 190, and there was no significant buildup of plant-related radionuclides in the environment due to the operation of the CCNPP.

January I - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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 Installation (ISFSI). The first dry fuel storage canister was loaded into the ISFSI in November of 1993, with more canisters being loaded in subsequent years. During this operating period, six additional canisters of spent fuel were transferred to the ISFSI.

Results of the monitoring program for the ISFSI for the current period are included in this report.

This report presents the content of the ISFSI REMP (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). Interpretation 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. Pressurized Ion Chambers (PICs), because they duplicate direct surveillance by TLDs and because they experience problems with reliability, were excluded from the Technical Specification portion of the ISFSI monitoring program. PIC results, however, are given in Table E-9 and will continue to be Non-ODCM surveillance to satisfy our commitment to the surrounding community.

The results were compared with that generated during the previous ISFSI pre-operational periods and the current and previous CCNPP REMP periods. These comparisons show little deviations from previous periods and are very close to the natural background levels of the region with the exception of TLDs around the north end of the ISFSI. More detailed discussions of these results are given in Section III. C.

21

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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,

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, Constellation Energy personnel according to Constellation Energy Laboratory Procedures (Ref. 4).

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.

lI.B.4 Program Exceptions There were no program exceptions during this operating period III.C. RESULTS AND DISCUSSIONS All the environmental samples collected were analyzed using Constellation Energy laboratory procedures (Ref. 4). 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).

22

January I - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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 in assessing the radiological impact of the ISFSI.

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 (SFAI), CCNPP Visitor's Center (SFA2), NNW of the ISFSI (SFA3), and SSE of the ISFSI (SFA4). These samples were an-alyzed for beta radioactivity and gamma emitting radionuclides.

Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic of levels routinely observed in the REMP. These values ranged from 0.3 x 10-2 to 3.4 x 10-2 pCi/m3 for the indicator locations and 0.5 x 10-2 to 2.8 x 10-2 pCi/m3 for the control location. The location with the highest overall mean of 1.6 x 10-2 pCi/m3 was SFA1, Met Station.

Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples. Naturally occurring radionuclides, such as Be-7, were detected in nearly all 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.

IR.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), SSE 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.

Cesium-137 was detected in four quarterly samples from both indicator and control locations.

The Cs-137 concentration ranged from 19 +17 to 59 +25 pCi/kg. This range is consistent with that found to be due to the residual fallout in wind-borne soil dust from past atmospheric nuclear weapons testing. No other detectable concentration of plant-related radionuclides were found in any of these samples. Naturally occurring radionuclides such as K-40 were detected in all samples.

23

January I - December 31, 2003 Docket Nos. 50-317/50-318/72-8 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), SSE 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 48 +20 to 547 +73 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 Part 190, "Environmental Radiation Protection Standards for Nuclear Power Operations" and are comparable to those observed in previous annual reporting periods for the CCNPP REMP and in the earlier pre-operational data for the ISFSI. No other detectable concentrations of plant-related radionuclides were found in any of these samples.

Naturally occurring radionuclides such as K-40, were also detected in all these samples.

IH.C.3 Direct Radiation Direct radiation is measured by a network of TLDs surrounding the ISFSI. These TLDs are collected quarterly from nineteen 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); NNW of ISFSI, (sample code SFDR2); North of ISFSI, (sample code SFDR3); NE of ISFSI, (sample code SFDR4); East of ISFSI, (sample code SFDR5); ESE of ISFSI, (sample code SFDR6); NNW of ISFSI, (sample code SFDR8); SSE of ISFSI, (sample code SFDR9); NW of ISFSI, (sample code SFDR10); WNW of ISFSI, (sample code SFDR1 1); WSW of ISFSI, (sample code SFDR12); South of ISFSI, (sample code SFDR13); SE of ISFSI, (sample code SFDR14); ENE of ISFSI, (sample code SFDR15); SSW of ISFSI, (sample code SFDR16); NNE of ISFSI, (sample code SFDR17) and West of ISFSI, (sample code SFDR18). Sampling locations are shown on Figures A-4 and A-5.

Following up on the correction cited in the Annual Radiological Environmental Operating Report for 2002, dealing with the sector positions of all the sites surrounding the ISFSI, two additional TLD sites were established during the fourth quarter to ensure that ambient radiation levels are measured in all sixteen meteorological sectors. These sites were designated as SFDRI 7 in the NNE sector of the ISFSI and SFDRI8 in the W sector of the ISFSI.

The mean 90 day ambient radiation measured at the ISFSI indicator locations was 25.27 mR and ranged from 9.65 to 68.86 mR as reported in Table 4. The control location showed a 90 day mean of 13.77 mR and ranged from 13.03 to 15.13 mR. A comparison of the mean and ranges of the current TLD data with those of both the historical data and the regional data (22-54, 10) reveals only one set of elevated TLD readings. That location with the highest overall mean of 24

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 47.00 mR with a range of 38.08 to 51.80 mR was SFDR1O, NW of ISFSI. These readings are consistent with those expected from the storage of spent fuel in the ISFSI (Refs. 22-54, 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.

III.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. No other plant-related radionuclide was observed in the environs of the ISFSI.

In general, the results in the following tables continue the historical trends previously observed at the official sites of the CCNPP REMP.

January I - December 31, 2003 Docket Nos. 50-317/50-318/72-8 APPENDIX C Quality Assurance Program Appendix C is a summary of Constellation Energy laboratory's quality assurance program. It consists of Table C-I which is a compilation of the results of the Constellation Energy Laboratory's participation in an intercomparison program with Environmental Resource Associates (ERA) located in Arvada, Colorado and Analytics, Inc. located in Atlanta, Georgia. It also includes Table C-2 which is a compilation of the results of the Constellation Energy Laboratory's participation in a split sample program with Teledyne Brown Engineering located in Knoxville, Tennessee and Table C-3 which is a list of typical MDAs achieved by Teledyne Brown for Gamma Spectroscopy.

All the Constellation Energy Laboratory's results contained in Table C-1 agree with the intercomparison laboratory results with the exception of a beta and a Ce-141 result for the filter sample type on 6/12/03 from Analytics. The filter sample was inadvertently inverted in the beta determination during the original analysis. This sample was correctly positioned in the counting chamber and rerun with the result of 68+1 pCi/filter, which is included in the table. This result was reevaluated using the NRC Resolution Test Criteria' and found to be in agreement. The Ce-141 result was also reevaluated using the same criteria and also found to be in agreement. The uncertainties for the Constellation Energy Laboratory's results and Analytics' results are +2U while the ERA laboratory's uncertainty is based on USEPA guidelines2. The results in this table are used as a check of instrumentation function and not meant to be used for reporting purposes of actual activity present in samples.

All the results contained in Table C-2 generally agree with their respective Constellation Energy Laboratory replicates and/or split laboratory samples, except for a Cs-1 37 result for a split soil sample collected 6/16/03 from SFS2 and the TLD replicate results for 9/30/03. The Cs-137 disagreement was due to the non-homogenous nature of the soil splits. When the split was returned to the Constellation Energy lab for analysis, the laboratory result was determined to be 131 +33 pCi/kg, which is in agreement with reported split result of 146 +4 pCi/kg. The disagreement on the TLD replicates was due to moisture present on some of the TLD assemblies which affected the instrument readings. The TLDs had been collected just after Hurricane Isabelle passed through the State of Maryland. As indicated in Table C-2 there were some instances where activity was observed in split samples, but not observed in the original sample.

This is due to the lower MDA achieved by the split laboratory using very long count times. Other samples whose nature generally precludes sample splitting are marked "**" in the Split Analysis column.

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 APPENDIX D Land Use Survey Appendix D contains the results of a Land Use Survey conducted around Calvert Cliffs Nuclear Power Plant during this operating period. A table listing the raw data of this survey and a discussion of the results are included in this appendix.

Discussion Table D-1 Land Use Survey A Land Use Survey was conducted to identify, within a distance of 5 miles, the location of the nearest milk animal, the nearest residence, and the nearest garden greater than 50 m2 in each of the nine sectors over land. A detailed description of the Land Use Survey is given in a separate document (Ref. 5). The position of the nearest residence and garden in each sector out to 5 miles is given in the adjacent table. No dairy animal was found within 5 miles in any direction. There are new residences located in the WNW sector within the 5-mile radius, but does not challenge the location of the nearest residence or garden.

Distance From Plant (miles)

Sector Residence Garden SE 1.4 1.4 SSE 1.7 1.8 S

1.6 2.0 SSW 1.6 1.6 SW 1.2 1.3 WSW 1.0 1.3 W

1.3 1.4 WNW 1.5 1.5 NW 2.0 2.0 The closest. residence is situated in the WSW sector and the nearest garden is in the WSW sector, which are in 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 REMP have been placed in the sectors with the highest X/Q. One sampling garden is located in the S sector at a distance of 0.4 miles, and another is situated near the site boundary in the SSE sector at a distance of 1.6 miles from the plant. These two sampling sites are considered good indicator locations for radioactive depositions around the plant.

The dose assessment using this operating period's meteorological data was performed, and no significant impact from the plant was found.

January 1 - December 31, 2003 Docket Nos. 50-317/50-318/72-8 APPENDIX E Additional Samples and Analysis Results Appendix E is a presentation of the analytical results for additional samples collected in the environs of CCNPP. These extra samples are not required by the ODCM (Ref. 2). Table E-1 lists the locations of all the additional samples and the remaining tables in this appendix provide the results. Some of these samples 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 PICs added for the ISFSI.

Table E-9 shows the average monthly direct radiation as measured by the pressurized ion chamber at five locations. The dose rate at the Met Station, PIC3, during the month of August was high. This result was due to spurious data spikes affecting the dose rate. These spurious spikes were caused by a corroded signal cable, which was subsequently cleaned and refurbished. The PIC was then put back in operation.

Table E-1I shows the direct radiation readings from TLDs placed at the perimeter of the Resin Storage Area which is a temporary waste resin storage and cask transfer area located to the west of the ISFSI facility. The TLD values are somewhat higher than those in the REMP program due to their proximity to this source of the radiation. However, when the direct radiation readings for the Resin Storage Area are compared with those from the ISFSI and Site Boundary TLDs, it is apparent that temporary storage of spent resin and cask transfers are having no significant, measurable effect on the environs surrounding CCNPP.
