II. Introduction The Clinton Power Station (CPS), consisting of one approximately 1140 MW gross electrical power output boiling water reactor is located in Harp Township, DeWitt County, Illinois. CPS is owned and operated by AmerGen Energy Company and became operational in 1987. Unit No. 1 went critical on 15 February 1987. The site encloses approximately 13,730 acres. This includes the 4,895 acre, man-made cooling lake and about 452 acres of property not owned by AmerGen. The plant is situated on approximately 150 acres. The cooling water discharge flume - which discharges to the eastern arm of the lake

- occupies an additional 130 acres. Although the nuclear reactor, supporting equipment and associated electrical generation and distribution equipment lie in Harp Township, portions of the aforementioned 13,730 acre plot reside within Wilson, Rutledge, DeWitt, Creek, Nixon and Santa Anna Townships.

A Radiological Environmental Monitoring Program (REMP) for CPS was initiated in 1987. The preoperational period for most media covers the periods May 1980 through 27 February 1987 and was summarized in a separate report. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Global Dosimetry, and Environmental Inc. (Midwest Labs) on samples collected during the period 1 January 2007 through 31 December 2007.

A. Objective of the REMP The objectives of the REMP are to:

1. Provide data on measurable levels of radiation and radioactive materials in the site environs.

2. Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.

B. Implementation of the Objectives The implementation of the objectives is accomplished by:

1. Identifying significant exposure pathways.

2. Establishing baseline radiological data of media within those pathways.

3. Continuously monitoring those media before and during Station operation to assess Station radiological effects (if any) on man and the environment.

Ill. Program Description.,

A. Sample Collection This section describes the general collection methods used by Environmental Inc. (Midwest Labs) to obtain environmental samples for the CPS REMP in 2007. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1 through B-3, Appendix B. The sampling methods used by Environmental Inc. (Midwest Labs) are listed in Table B-2.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, well water, fish, and shoreline sediment. Two gallon water samples were collected monthly from continuous samplers located at three surface water locations (CL-90, CL-91 and CL-99), and one drinking water location (CL-14). A monthly grab sample was obtained from one surface water location (CL-13).

Quarterly samples were obtained from two well water locations (CL-07D and .CL-12). AlI:samples were collected in new unused plastic bottles, which were.rinsed at leasttwice with source.water prior to collection. Fish samples comprising:theflesh of largemouth bass, crappie, carp, and bluegill, the species most commonly harvested from the lakes by sporting fishermen, were collected semiannually at .two locations, CL-19 and CL-105 (control). Shoreline sediment samples composed of recently deposited substrate were collected at one locationý.semiannually, CL-07B.

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate, airborne iodine, milk, food produce and grass. Airborne iodine and particulate samples were collected and analyzed weekly at ten locations (CL-01, .CL-02, CL-03, CL-04, CL-06, CL-07, CL-08, CL-11, CL-15, and CL-94). The control location was CL-11.

Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The filters, were replaced weekly and sent to the laboratory for analysis.

Milk samples were collected biweekly at one location (CL-1 16) from May through October, and monthly from November through April to coincide with the grazing season. All samples were collected in new unused U

plastic bottles from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory.

Food products were collected once a month from June through September at four locations (CL-1 14, CL-1 15, CL-1 17 and CL-1 18). The control location was CL-1 14. Various broadleaf vegetable samples were collected and placed in new unused plastic bags, and sent to, the laboratory for analysis.

Grass samples were collected biweekly at four locations (CL-01, CL-02, CL-08 and CL-1 16) from May through October. The control location was CL-116. All samples were collected in new unused plastic bags and sent to the laboratory for analysis.

Ambient Gamma Radiation q Direct radiation measurements were made using Panasonic 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations were placed around the CPS site as follows:

An innerring consisting of 16 locations (CL-O1 ,CL-05, CL-22, CL-23, CL-24, CL-34, CL-35, CL-36, CL-42 CL-43, CL-44,CL-45, CL-46, CL-47,

.CL-48 and CL-6 3) near and within the site perimeter.

An outerring consiSting'of 16 locations (CL-51, CL-52, CL-53, CL-54, CL-55, CL'-56, CL-57, CL-58, CL-60, CL-61, CL-76, CL-77, CL-78, CL-79, CL-80and CL-81) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.

As ialnterest set consisting of seven locations (CL-37, CL-41, CL-49, CL-64, CL65, CL-74 and CL-75) representing special interest areas.

A supplm.ental set consisting of 14 locations (CL-02, CL-03, CL-04, CL-06,. CL-07, CL-08, CL-i5, CL-33, CL-84, CL-90, CL-91,, CL-97, CL-99, and CL-114).

The balance of 1 location (CL-1 1) representing the control station.

The' specific TLD locations were determined by the following criteria:

1. The presence of relatively dense population;

2. Site meteorological data taking into account distance and elevation for each of the sixteen-22 1/2 degree sectors around the site, where estimated annual dose from CPS, if any, would be most significant;

3. On hills-free from local obstructions and within sight of the vents (where practical);.

4.-,. And near the closest: dwelling to the HVAC stacks in the prevailing downwind direction.

Two TLDs - each composed of two CaSO4 thermoluminescent phosphors enclosed in plastic - were placed at each location in a vented PVC conduit located approximately three feet above ground level. The TLDs were exchanged quarterly and sent to Global Dosimetry for analysis.

B. Sample Analysis This section describes the general analytical methodologies used by TBE and Environmental Inc. (Midwest Labs) to analyze the environmental samples for radioactivity for the CPS REMP in 2007. The analytical procedures used by the laboratories are listed in Table B-2.

In order to achieve the stated objectives, the current program includes the following analyses:

1. Concentrations of beta emitters in drinking'water and air particulates.

2. Concentrations of gamma emitters in surface, drinking and well water, air particulates, milk, fish, grass, sediment and vegetables.

3. Concentrations of tritium ,in surface, drinking and well water. /1

4. Concentrations of .1-131 in air,. milk, vegetables and drinking water.

5. Ambient gamma radiation levels at various on-site and off-site environs.

U C. Data Interpretation The radiological and direct radiation data collected prior to CPS becoming operational was used as a baseline with which these operational data were compared. For the purpose of this report, CPS was considered operational at initial criticality. In addition, data were compared to previous years' operational data for consistency and trending. Several factors were important in the interpretation of the data:

Im 9

al 0

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) was defi~ned as thesmallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concludingithat a blank observation represents a "real" signal. The LLD was intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criteria for the presence of activity. All analyses were designed to achieve the required CPS detection capabilities for environmental sample analysis.

2. Net Activity Calculation and Reporting of Results Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations may result in sample activity being lower than, the background activity resulting in a negative number. An MDC was reported in all cases where positive activity was not detected.

Gamma spectroscopy results for each type of sample were

..grouped as follows:.

For surface water and well water 12 nuclides, Mn-54, Co-58, Fe-59, Co-60-Zn-65,-Nb-95, Zr-95,-Cs-134, Cs-137, Ba-140, La-140, and Ce-144 were reported.

For fish,ý sediment and milk, 14 nuclides, Be-7, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, Cs-134, Cs-137, Ba-140, La-140, and Ce-144 were reported.

For drinking water, grass and vegetation 13 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, 1-131, Cs-134, Cs-137, Ba-140, La-140, and Ce-144 were reported.

For grass 15 nuclides, Be-7, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65,-Nb-95, Zr-95, 1-131, Cs-134, Cs-137, Ba-140, La-140, and Ce-144 were reported.

For air particulate 11 nuClides, Be-7, K-40, Co-60, Nb-95, Zr-95, Ru-103, Ru-106, Cs-134, Cs-137, Ce-141 and Ce-144, were reported.

Means and standard deviations of the results were calculated. The standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty. j D. Program Exceptions The exceptions described below are those that are considered 'deviations' from the Radiological Environmental Monitoring Program as required by the Station's ODCM. By definition, 'deviations' are permitted as delineated within NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants", October 1978, and within Radiological Assessment Branch Technical Position, Revision 1, 3' November 1979, which states.... "Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons".... The below section addresses the reporting requirements found within Section 7.1 of the Station's ODCM. 1 April 16,2007, IR #00618289 H.

Only one kilogram of -crappie -was 'collected from the fish control station Cl-105',, due, to "both. low "lake level and water temperature of 48-50 degrees. The coves where fish tend to migrate were either non-existent or at too low a depth and the low water temperatures cause the fish to, migrate towards deeper water, which challenges the ability "of the electro-shocking process. Although the fish 'volume-Was one kilogram, ,n all required LLDs were met and there was no impact to the results.

July 04, 2007 - November 07, 2007 IR # 006957271 Non-ODCM Composite Water Sampler, CL-99., displayed sporadic performance throughout the summer. Surface water station CL-99 serves as a supplement to the ODCM. Grab sampling was augmented during periods of troubleshooting and repairs when consistent compositing was either too much or too little. There was no impact on the results, and all LLDs were met.

July 25, 2007, IR # 00653836 Clinton's second quarter 2007 H-3 composite sample for surface water station CL-90 was missing the June contribution. Although the Licensee complied by collecting the required sample, before arriving at the vendor for analysis, the sample was inadvertently disposed of by the sample collecting vendor.

July 30, 2007, IR 00655565 Air samplers CL-02 and CL-03 were found not operating during the weekly surveillance. Although trouble-shooting determined a blown fuse, there was sufficient sampling volume collected such that there was no impact to the results, and all required LLDs were achieved.

October 08, 2007, IR # 00681664, ODCM Drinking Water Compositor CL-14 had a loss of power for 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br /> due to a 138 KV Line Outage. This resulted in a less than 2% loss of composite sampling to what is typically collected over a month; four (4) gallons of water. There was no impact to the results, and all required LLDs were achieved.

November 28, 2007 - December 05, 2007 IRA#00707575 Non-ODCM environmental Air Sampler CL-06 was found not running during the performance of the weekly surveillance due to a loss of power. Sample volume calculations revealed that the minimum sample volume had not been achieved. Air Sampler CL-06 serves as a special interest supplement to the ODCM.

Each program exception was reviewed to understand the causes of the programexception. Sampling and maintenance errors were reviewed with

-the personnel involvedto. preyent recurrence., Occasional equipment breakdowns.. and power outages were unavoidable.

The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program imp.lementation.

E. Program Changes Starting in 2007, the mean and two standard deviation values are calculated using the positive values only.

IV. -Results and'Discussion A. Aquatic Environment

.1. Surface Water Samples were taken hourly, and grab samples to supplement during periods of inoperability - see exceptions, from a continuous compositor at three locations (CL-90, CL-91 and CL-99) on a monthly schedule and grab samples were taken monthly from one station (CL-13). The following analyses were performed.

Tritium Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-1.2, Appendix C). The required LLD was met.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-1.3, Appendix C). Naturally occurring K-40 was

,found in three of 12 samples at locations CL-13 and CL-91 and one of 12 samples at locations CL-90 and CL-99. No other nuclides were detected and all required LLDs were met.

2., Drinking.Water- ., .  :

Monthly samples were collected from a continuous compositor at one location (CL-14). The following analyses were performed:

GrossBeta Monthly samples were analyzed for concentrations of gross beta (Tables C-11.1, Appendix C). Gross beta was found in three of 12 samples. The values ranged from 1.9 to 3.5 pCi/l. Concentrations detected were consistent with those detected in previous years.

3. Ground Water Quarterly grab samples were collected at two locations (CL-7D and CL-12, consisting of CL-12R [a raw water sample from this well]

and CL-12T [same well water, but after treatment and available for consumption]). The following analyses were performed:

Samples from all locations were analyzed for tritium activity (Table C-111.1, Appendix C). The-required LLD was met.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-111.2, Appendix C). No nuclides were detected and all required LLDs were met.

4. Fish Fish samples comprised of carp, bass, bluegill, crappie and channel Scatfish were Collected at two locations (CL-19 and CL-1 05) semiannually. The following analysis was performed:

Gamma Spectrometry .

The edible portion of fish samples from both locations was analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C).

'Naturally occurring K-40 was foundat both stations. No fission or activation products were found. No other nuclides were detected and the required LLDs were met.

5. Shoreline Sediment Aquatic shoreline sediment samples were collected at CL-07B semiannually. The following analysis was performed:

B. Atmospheric Environment

1. Airborne

a. Air Particulates I Continuous air particulate samples were collected from 10 locations on a weekly basis. The 10 locations were separated into three groups: Group I represents locations within one mile of the CPS site boundary (CL-02, CL-03, CL-04, CL-06, CL-15, and CL-94). Group II represents the locations at an intermediate distance within one to five miles of CPS (CL-01, CL-07, and CL-08), and Group III represents the control location greater than five miles from CPS (CL-1 1).. The following analyses were performed:

Weekly samples were analyzed for concentrations of beta emitters (Table C-VI.1 and C-VI.2 and Figure C-1, Appendix C). .-.

Detectable gross beta activity was observed at all locations.

Comparison of results among .the three groups aid in determining the effects, if any, resulting from the operation of CPS. The results from the On-Site locations (Group I) ranged from 22 to. 45 E-3 p~i/m3 with a mean of 22 E-3 33 pCi/m3. The results from the Intermediate Distance location (Group 11)ranged from 9 to 45 E-3 pCi/m 3 with a mean of 21 E-3 pCi/m 3 . The results from the Control locations (Group Ill) ranged from 8 to 39 E-3 pCi/m 3 with a mean of 22 E-3 pCi/m 3 . Comparison of the 2007 air particulate data with previous years data indicate no effects from the operation of CPS (Figure C-5, Appendix C). -In addition a comparison of the weekly mean values for 2007 indicate no notable differences among the three groups.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic 814 (CaSO 4 ) thermoluminescent dosimeters. Fifty-four TLD locations were established around the site. Results of TLD measurements are listed in Tables C-X.1 to C-X.3, Appendix C.

A total of 216 TLD measurements were made in 2007. The average dose from the inner ring was 21.1 mR/quarter. The average dose from the outer ring was 21.2 mR/quarter. The average dose from the special interest group was 21.3 mR/quarter. The average dose from the supplemental group was 20.3 mR/quarter. The quarterly measurements ranged from 15.9 to 24.1 mR/quarter. The inner ring and outer ring measurements compared well to the control station, CL-11, which ranged from 18.2 mR/quarter to 20.7 mR/quarter with an average measurement of 19.9 mR/quarter. A comparison of the Inner Ring and Outer Ring data to the Control Location data indicate that the ambient gamma radiation levels from all the locations were comparable. The historical ambient gamma a

radiation data from the control location were plotted along with similar data from the Inner and Outer Ring Locations (Figure C-2, Appendix C).

D. Land Use Survey A Land Use Survey conducted during the July through October 2007 growing season around the Clinton Power Station (CPS) was performed by Environmental Inc. (Midwest Labs) for AmerGen to comply with Clinton's Offsite Dose Calculation Manual, section 5.2. The purpose of the survey was to document the nearest resident, milk producing animal and garden of greater than 538 ft2 in each of the sixteen 22 11/2 degree sectors around the site. The distance and direction of all locations from the CPS Station HVAC vent stack were positioned using Global Positioning System (GPS) technology. There were no changes required to the CPS REMP, as a result of this survey. The results of this survey are summarized below.

E. Summary of Results -,Inter-Laboratory Comparison Program I The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices'for 19 analytes (Appendix D). The PE samples, supplied by I

Analytics Inc., Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following'pre-set acceptance criteria:

U I

I a

Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.

2. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.

The MAPEP defines three levels of performance: Acceptable (flag =

"A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value.

Performance is acceptable with warning when a mean result falls in the range from +/- 20% to +/- 30% of the reference value (i.e., 20% <

bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.

For the primary laboratory, 17 out of 19 analytes met the specified acceptance criteria. Two samples did not meet the specified acceptance criteria for the following reasons:

1. Teledyne Brown Engineering's Analytics March 2007 1-131 in charcoal result of 34.7 pCi was lower than the known value of 71.3, resulting in a found to known ratio of 0.49. A new technician counted the charcoal cartridge on the back rather than the face side. Due to decay of the 1-131, recounting could not be performed.

Counting the 2 nd quarter Analytics charcoal cartridge on the face and the back resulted in approximately 220% more activity on the face of the cartridge. This indicates that TBE would have had acceptable results (ratio approximately 1.07) if the cartridge had I

been.counted on the face side. The investigation was documented by Nonconformance Report NCR 07-02.

2. Teledyne BroWn Eng ineering's ERA July 2007 Cs-134 result of 57.6 pCi/L exceeded the lower acceptance limit of 60.2 pCi/L. The high activity of the sample resulted in the lower acceptance limit of 8.66, although the ratio of found to known was 83.6%, which is considered acceptable by TBE. The investigation was documented by Nonconformance Report NCR 07-07. 3 For the secondary laboratory, 18 out of 19 analytes met the specified acceptance criteria. One sample did.not meet the specified acceptance criteria for the following reason:

1. Environmental Inc.'s ERA March 2007 air particulate Cs-137 result of 345.3 pCi/L exceeded the upper control limit of 336 pCi/L. The reported result was calculated using composite filter geometry rather than the single filter geometry. The recalculated result of 305.8 pCi/filter fell within the acceptance limits. This was entered into their June 2007 Program Deviation Report.

The Inter-Laboratory Comparison Program provides evidence of theI counting systems andjmethods, and that the laboratories are producing accurate and reliable data...
