SUMMARY

During the 2002 operating period for Calvert Cliffs Nuclear Power Plant (CCNPP) Units I and 2, a total of 3343 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. 6) and the'Environrental and Independent Spent Fuel Storage Installation (ISFSI) Technical Specifications (Ref. 4, 54). 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 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 656 radiochemical analyses were performed on 588 environmental samples, and 552 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 6) and the Environmental Technical Specifications (Ref. 4).

For the ISFSI monitoring program, 358 radiochemical analyses were perforned on 298 environmental samples, 51 of which were in common with the original REMP. In addition, 432 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. 6) and the ISFSI Technical Specifications (Ref. 54).

In addition, 594 analyses were perforned on 546 additional environmental samples, and 480 additional TLDs were analyzed for arnbient radiation exposure rates. Also, six pressurized ion chambers continuously monitored the environs around the plant for ambient radiation levels. 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 comnunity.

And lastly, 205 radiochemical analyses were performed on 189 quality assurance samples and 66 quality assurance TLDs were analyzed as part of an internal and external quality assurance program associated with Enrad Laboratories (Duke' Power Company). vLaboratory 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 I1

January 1 - December 31, 2002 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 3343 radiological analyses performed in the year 2002. Low levels of various man-made fission and activation products were also observed in 39 of these analyses. Thirty-one of these observations were attributed to fallout from past atmospheric weapons testing, while eight analyses yielded low level positive results for the presence of H-3 or Ag- 1Om, 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 for 2002 indicate:

a. a maximum thyroid dose of 3.09 x l- -mR via liquid and gaseous pathways, which is less than 0.0 1% of the acceptable limit of 75 mR/yr as specified in 40 CFR Part 190;

b. a maximum whole body dose of 7.48 x 0-3 mR via liquid and gaseous pathways, which is less than 0.1% of the acceptable limit of 25 mR/yr as specified in 40 CFR Part 190;

c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 1.74 x 10- mR to the GI-Tract. This dose is less than 1% of the allowable limit of 25 mR/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 during 2002.

January 1 - December 31,2002 Docket Nos. 50-317150-318/72-8 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 (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.

Originally, the REMP was conducted under separate Environmental Technical Specifications (Ref. 1,2). On July 29, 1977 the monitoring program began operation under a combined set of Technical Specifications (Ref. 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 (Ref. 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 (Ref. 6) in accordance with Generic Letter 89-01 (Ref. 5).

Results of the monitoring program for the pre-operational and previous operational periods through December 31,2001 have been reported in a series of documents (Ref. 16-53).

Results of the monitoring program for the current operational period of January 1,2002 through December 31, 2002 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 of 2002 (Table 2), a compilation of the analytical data for 2002 (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 in 2002 (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 during 2002.

I January 1 - December 31, 2002 Docket Nos. 50-317/50-318/72-8 II.B. PROGRAM II.B.1 Objectives The objectives of the REMP for the CCNPP are:

a. To verify that radioactivity and ambient radiation levels attributable to plant operation are within the limits specified in the ODCM (Ref. 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-1 and shown in Figures A-2 and A-3. All samples were collected by contractors to, or personnel of CEG according to CCNPP Procedures (Ref. 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 Pro2ram Exceptions There were no program exceptions during 2002.

II.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using Constellation Generation Group, LLC (CGG) laboratory procedures (Ref. 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).

January 1 - December 31, 2002 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.-

Il.C.l.a Bay Water Monthly bay water sanples 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 tritiun and gamma emitters.

The tritium analyses, performed on quartrly composites of the monthly bay water samples, showed the presence of tritium in the Discharge (Wa2) and the Intake (Wal) samples in two 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 87 +/-36 to 195 439 pCilL, and in the Intake ranged from 49 37 to 84 4+/-35 pCi/L which are similar to those ranges observed in previous years, (Ref. 22-53).

Figure 1 compares tritium observed in the plant discharge and intake with annual effluent releases in 2002 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.l.b Aguatic 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 lal and Ia2) and from the Patuxent River (sample codes Ia4 and IaS). 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 Ia3) and Kenwood Beach (Ia6). Edible portion of the fish and oyster samples were analyzed for gamma emitters.

5

January 1 - December 31, 2002 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 exhibited naturally occurring K-40 and low levels of detectable concentrations of the plant-related radionuclide, Ag- 1Oim, in samples obtained from Camp Conoy (a3). The concentration of naturally occurring K40 ranged from 1741 to 2144 pCi/kg while the concentrations of Ag- 1Om, which are consistent with that expected due to liquid effluents from the plant in 2002, ranged from 19 b7 to 55 +/-8 pCi/kg.

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 naturally occurring radionuclides, such as K40, which ranged from 447 to 616 pCi/kg, but no detectable concentrations of any plant-related radionuclides.

January 1 - December 31, 2002 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 (Ref. 16-53). The values ranged from 0.2 x 10-2 to 5.1 x 10-2 pCi/m 3 for the indicator locations and 0.9 x 10-2 to 2.8 x 10-2 pCi/m3 at the control location. The location with the highest overall mean of 1.7x10-2 pCi/m3 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. 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-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, 2002 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, b5, and Ib6), and the Emergency Operations Facility (sample codes Ib7, Ib8, and 1b9). These samples were analyzed for gamma emitters, including analyses for 1-131.

Cesium-137 was detected at a concentration of 116 pCi/kg in a single broccoli sample from the EOF. This result is consistent with that found to be due to residual fallout in wind-borne soil dust from past atmospheric weapons testing (Ref. 22-53). No other detectable cohncentrations of plant-related radionuclides were found in any of these samples. All samples showed detectable amounts of naturally occurring K-40 in the ranges from 1424 to 3691 pCi/kg and naturally occurning Be-7 in the range of 52 to 322 pCi/kg.

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.

TLDs 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 (sarple 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 DRI 5), Appeal School (sample code DRI 6), Cove Point and Little Cove Point Roads (sample code DR17), Cove Point (sample code DRI8), Long Beach (sample code DR19), and On Site Near Shore (sample code DR20). The three control locations are the Emergency Operations Facility (sample code DR21), 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 11.20 mR and ranged from 5.72 to 16.50 mR as reported in Table 2. The control locations showed a 90 day mean of 12.44 mR with ranges from 7.53 to 18.29 mR. The location with the highest overall mean of 15.43 was DR23, Taylors Island, Carpenters Property, which ranged from 11.72 to 18.29 mR. A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data (Ref. 22-53) shows no plant-related contribution to the measured direct radiation exposure for 2002. 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, 2002 Docket Nos. 50-317/50-318/72-8 II.D. CONCLUSION Low levels of various man-made fission by-products were observed in the environment surrounding the plant during 2002. 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., tritium in quarterly composited bay water samples and Ag-i l Om in oysters).

Historical trends for tritium in bay water, Ag-1 1Om 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 2002.

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 1.19 x 10-3 mR to a child via the plume, ground, vegetable, meat, and inhalation pathways at 2.3 km SW of Calvert Cliffs. This is less than 0.01% of the acceptable limit of 75 mR/yr as specified in 40 CFR Part 190,-"Environmental Radiation Protection Standards for Nuclear Power Operations."

A maximum whole body gamma dose of 2.91 x 1 0 4 mR to a child at 2.1 km SE of Calvert Cliffs, which is about 0.001% of the acceptable dose limit of 25 mR/yr as specified in 40 CFR Part 190.

A maximum dose to any other organ, in this case the skin, of 9.40 x 104 mR to all age groups at 2.1 km SE of Calvert Cliffs. This is about 0.01% of the acceptable dose limit of 25 mR/yr as specified in 40 CFR Part 190.

Liguid Pathways A maximum thyroid dose of 1.90 x 10-3 mR to a teenager for all liquid pathways, which is less than 0.0 1% of the acceptable dose limit of 75 mR/yr as specified in 40 CFR Part 190.

A maximum whole body dose of 7.19 x 103 rmR to a child via all liquid pathways, which is about 0.03% of the acceptable dose limit of 25 mR/yr as stated in 40 CFR Part 190.

13

I -

January 1 - December 31, 2002 Docket Nos. 50-317/50-318/72-8 A maximum dose to any organ, in this case the GI-Tract, of 1.74 x 10-1 mR to an adult for all pathways, which is less than 1% of the acceptable dose limit of 25 mR/yr specified in 40 CFR Part 190.

Gaseous and Liquid Pathways Combined A maximum thyroid dose of 3.09 x10-3 mR via liquid and gaseous pathways, which is less than 0.01% of the acceptable limit of 75 mR/yr specified in 40 CFR Part 190.

A maximum whole body dose of 7.48x10- 3 mR via liquid and gaseous pathways which is less than 0.1% of the acceptable limit of 25 mR/yr as specified in 40 CFR Part 190.

A maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 1.74 x10-1 mR to the GI-Tract. This dose is about 1% of the.

allowable limit of 25 mR/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 1 - December 31, 2002 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 ISFSI. The first dry fuel storage canister was loaded into the ISFSI in November of 1993, with more canisters being loaded in subsequent years. In the year 2002, four additional canisters of spent fuel were transferred to the ISFSI.

Results of the monitoring program for the ISFSI for the current period of January 1, 2002 through December 31, 2002 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 with the exception of the Pressurized Ion Chambers (PICs). 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 (Ref. 9). 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 for 2002 were compared with that generated during the previous ISFSI pre-operational periods (Ref. 10) and the current and previous CCNPP REMP periods (Ref. 22-53).

These comparisons demonstrate the consistency of data throughout the CCNPP site; which are very close to the natural background levels for the region. More detailed discussions of these results are given in Section III. D.

Recently, all the historical sites associated with ISFSI that are depicted on the maps in Figures A4 and A-5 were resurveyed using Global Positioning Systems and satellite imaging.

As a result of this survey, the sector overlays depicted in previous representations of Figures A-4 and A-5 were found to be in error by about 15 degrees in the counter clockwise direction. This error was corrected based on this new survey and therefore some site sector designations were changed. These revisions are reflected in the current maps and table that appear in Figures A-4, A-5 and Table 'A-2.

January 1 - December 31, 2002 Docket Nos. 50-317/50-318/72-8 III.B. PROGRAM III.B.1 Objectives The objectives of the REMP for the ISFSI are:

a. To satisfy 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 CGG according to CGG Laboratory Procedures (Ref. 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 2002 III.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year 2002 were analyzed using CGG's laboratory procedures (Ref. 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).

January 1 - December 31, 2002 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 (SFA1), 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 (Ref. 22-53). These values ranged from 0.7 x 10-2 to 3.2 x 10-2 pCi/m3 for the indicator locations and 1.0 x 10-2 to 4.3 x 10-2 pCi/m 3 for the control location. The location with the highest overall mean of 1.9 x 10-2 pCi/m 3 was SFA2, Visitor's Center.

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 TerrestrialEnvironment 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), SSE of the ISFSI (sample code SFb4), and On Site before the Entrance to Camp Conoy (sample code SFbS). These samples were analyzed for gamna emitters.

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

The Cs-137 concentration ranged from 16 46 to 24 +8 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 in wind-bome soil dust from past atmospheric nuclear weapons testing (Ref. 22-53). No other detectable concentration of plant-related radionuclides were found in any of these 23

January 1 - December 31, 2002 Docket Nos. 50-317/50-318/72-8 samples. Naturally occurring radionuclides such as K-40 which ranged from 306 to 7395 pCi/kg were detected in all samples.

III.C.2.b Soils -4 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 thirteen quarterly samples from both indicator and control locations. The Cs-137 concentrations ranged from 49 +/-25 to 866 +71 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 (Ref. 22-53) and in the earlier pre-operational data for the ISFSI (Ref. 10). No other detectable concentrations of plant-related radionuclides were found in any of these samples. Naturally occurring radionuclides such as K-40, which ranged from 2031 to 8599 pCi/kg were also detected in all these samples.

III.C.3 Direct Radiation Direct radiation is measured by a network of TLDs surrounding the ISFSI. These TLDs 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 SFDR1); North 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 SFDRI 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); and SW 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 21.65 mR and ranged from 8.07 to 50.49 mR as reported in Table 4. The control location showed a 90 day mean of 13.45 mR and ranged from 12.09 to 14.93 mR. A comparison of the mean and ranges of the current TLD data with those of both the historical data and the regional data (22-53, 10) reveals only one set of elevated TLD readings. That location with the highest overall mean of 44.36 mR with a range of 35.34 to 50.49 mR was SFDR1O, NW of ISFSI. These readings are consistent with those expected from the storage of spent fuel in the ISFSI (22-53, 10). A 24

January 1 - December 31, 2002 Docket Nos. 50-317/50-318/72-8 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 during -2002.

In general, the results in the following tables continue the historical trends previously observed at the official sites of the CCNPP REMP (Ref. 22-53).

January 1 - December 31, 2002 Docket Nos. 50-317/50-318/72-8 APPENDIX C Quality Assurance Program Appendix C is a summary of CGG Laboratory's Quality Assurance Program. It consists of Table C-I which is a compilation of the results of the CGG Laboratory's participation in an intercomparison program in 2002 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 CGG Laboratory's participation in a split sample program with Enrad Laboratories (Duke Power) located in Huntersville, North Carolina and Table C-3 which is a list of typical MDAs achieved by Enrad Laboratories for Gamma Spectroscopy.

All the CGG Laboratory's results contained in Table C-1 agree with the intercomparison laboratory results with the exception of a Cs-134 result for the filter sample type on 6/13/02 from Analytics and four out of five isotopes for a water sample type from ERA on 8/21/02. The Cs-134 result was reevaluated using the NRC Resolution Test Criteria' and found to be in agreement. The water sample on 8/21/02 was reanalyzed and the remaining four isotopes were found to be in agreement with the exception of Zn-65 which was found to be in agreement using the NRC Resolution Test Criteria'. The corrected results are included in the table. The uncertainties reported for the filter sample types for both laboratories are expressed as +/-3 . The uncertainties for the CGG Laboratory's other sample types are +/-1 and the cross check laboratory's uncertainty is based on USEPA guidelines 2 . 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 CGG Laboratory replicates and split laboratory samples, except for the Ag- 1Om result for an oyster sample collected 9/4/02. This disagreement is due to the poor condition of the sample when it arrived at the split laboratory. When the originally prepared sample was sent to the laboratory the Ag-I Om result was determined to be 52 +/-4 pCi/kg which is in agreement with the original result. 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, 2002 January - December 31, 2002 Docket Nos. 50-317/50-318/72-8 APPENDIX D Land Use Survey Appendix D contains the results of a Land Use Survey (Ref. 12) conducted around CCNPP during August 2002. A table listing the raw data of this survey and a discussion of the results are Table D-1 included in this appendix. Land Use Survey Discussion Distance From Plant (km)

A Land Use Survey was conducted during Sector I Residence Garden August 2002 to identify, within a distance of SE 2.7 2.7 8 km, the location of the nearest milk animal, the SSE 2.9 2.9 nearest residence, and the nearest garden greater S 3.1 7.2 than 50 m 2 in each of the nine sectors over land.

SSW 2.6 2.7 A detailed description of the Land Use Survey is SW 2.1 2.4 given in a separate document (Ref. 12). The WSW 1.9 1.9 position of the nearest residence and garden in W 2.1 2.4 each sector out to 8 km are given in the adjacent WNW 2.6 2.6 table. No dairy animal was found within 8 km in NW 2.9 2.9 any direction. There has not been any significant change in the use of local lands in the last few years.

The closest residence and nearest garden is 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 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 0.7 km, and another is situated near the site boundary in the SSE sector 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 2002 meteorological data was performed, and no significant impact from the plant was found.

January 1 - December 31,2002 Docket Nos. 50-317/50-318/72-8 APFENDIX E Additional Samples and Analysis Results Appendix E is a presentation of the analytical results for additional samples collected in the environs of CCNPP during the year 2002. These extra samples are not required by the ODCM (Ref. 6).

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 rates at the south end of the Old Steam Generator Storage Facility (OSGSF) took a slight step increase when the old steam generators were placed into the building in 2002. On April 2 and April 3, PIC4 (NNW of ISFSI) showed a step increase in dose rate as a result of the transfer of 11 Steam Generator and 12 Steam Generator into the storage facility. The slight increase in dose rate was localized at SFDR02 and TLDs located in the immediate vicinity of the building showed no appreciable increase for the calendar quarter.

Sampling around the OSGSF was also increased with the addition of TLDs around the building.

Table E-1 0 lists those results for 2002.

Table E-I1 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 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.
