In assessing all the data gathered for this report and comparing these results with preoperational data, it was, concluded that the operation of CPS had no adverse radiological impact on the environment.
There were zero (0) radioactive liquid releases from CPS during 2013.Releases of gaseous radioactive materials were accurately measured in plant effluents.
There were no gaseous effluent releases that approached the limits specified in the CPS Offsite Dose Calculation Manual (ODCM). The highest calculated offsite dose received by'a member of the public due to the release of gaseous effluents from CPS was 2.65 E-02:or 0.027 mRem.Surface, drinking, and Well water samples were analyzed for concentrations of tritium and gamma emitting nuclides.
Drinking water samples were also analyzed for concentrations of gross beta and 1-131. Naturally occurring K-40 was detected at levels consistent with those detected in previous years. No fission or activation products were detected.
No tritiurm dr gross beta activity was detected and the required lower limit of detection (LLD) was met.Fish and shoreline sediment samples were analyzed for concentrations'of gamma emitting nuclides.
No fission or activation products were detected in fish or shoreline sediment samples.Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides.
Cosmogenic Be-7 was detected at a level consistent with those detected in previous years. No fission or activation products were detected.High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable concentration for 1-131.Cow milk samples were analyzed for concentrations of 1-131 and gamma emitting nuclides.
All results were below the required LLDs for 1-131.Concentrations of naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were found.Food product samples were analyzed for concentrations of gamma emitting nuclides.
Concentrations of cosmogenically produced Be-7 and naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were detected.Grass samples were analyzed for concentrations of gamma emitting nuclides.Concentrations of cosmogenically produced Be-7 and naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were detected.Environmental gamma radiation measurements were performed quarterly using Optically Stimulated Luminescence Dosimeters (OSLD). ,Beginning in 2012, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry (OSLD) were deployed and Thermo-luminescent Dosimetry (TLD) were discontinued.
A step change increase on the order of 10% has, been observed as a result of the application of the alternate methodology.
The relative comparison to'control locations remains valid. OSLD technology is different than that Used in aTLD but has~the same purpose (to measure direct radiation). * .I' iI II , ...I.... , ......, ..., , ...I: " .'." ..." '.I a-2-,I"', ':' 'i ." " " I II. Introduction.The. ClintonPower:
Station (CPS), consisting of one approximately 1,140 MW grosselectrical power output boiling water reactor is located in Harp Township, DeWitt County, Illinois.
CPS -is owned and operated by Exelon 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 Exelon. 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) and Landauer on samples collected during the period 1 January 2013 through 31 December 2013.A. Objectives 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 3 A. Sample Collection This section describes the general collection methods used by Environmental Inc. (Midwest Labs) to obtain environmental samples for the CPSIREMP in 2013. 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. 3..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-7D and CL-12). All samples were collected in new unused plastic bottles, which were rinsed at least twice with source water prior to collection.
Fish samples comprising the flesh-of largemouth bass, crappie, carp, bluegill, and 6hannel catfish; the species most commbnly harvested from the lakes by sporting fishermen, were collected semiannually at two locations, CL-19 and CL-105. CL-105 was the control location.
Shoreline sediment samples.composed of recently deposited substrate were collected at two locations semiannually (CL-7B and CL-1 05 (control)).
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-1, CL-2, CL-3, CL-4, CL-6, CL-7, CL-8, CL-11, CL-1i5and CL-94)!. CL-11 was the control.location.
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 arid'sampled air at the -rate of approximately one cubic foot per minute. The filters were replaced weekly and sent to thelaboratory for analysis.Milk samples were collected biweekly at one-location (CL-1 16) from May through November and monthly from December through April to coincide with the grazing season. All samples were collected in new unused-4 plastic bottles from the bulk tank at that 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-1, CL-2, CL-8 and CL-1 16) from May through October. CL-1 16 was the control location.
All samples were collected in new unused plastic bags and sent to the laboratory for analysis.Ambient Gamma Radiation.
Direct, radiation measurements were made using A120 3:C Optically Stimulated, Luminescence Dosimetry (OSLD). Eachlocation consisted of 2 OSLD sets. The.OSLDs were. exchanged quarterly and sent to Landauer for analysis.
The OSLD locations.were placed around the CPS site as follows: An inner ring consisting of 16 locations (C.L-1, CL,5, CL-22',,CL-23, CL-24, ,CL-34, CL-35,.CL-36, CL-42 CL-43, CL44, CL-45, CL-46, CL-47, CL-48 and CL-63).: , .An outer ring 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-80 and CL-81). CL-58MM was installed as part of a volunteer comparison study extending to approximately 5 miles from the site.Aspecial interest set consisting of seven locations (CL-37, CL-41, CL-49, CL-64, CL65, CL-74 and CL-75) representing special interest areas.A supplemental set consisting of 14 locations (CL-2, CL-3, CL-4, CL-6, CL-7,.CL-8, CL-15,-.CL-33, CL-84, CL-90, CL-91, CL-97, CL-99 and CL-114) .. .. .CL-i 1: represents the control ocation for all environmental TLDs.The specific OSLD 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 thesixteen-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 andwithin sight of the vents t(where practical);
3 4. And near the closest dwelling to the HVAC and VG stacks in the prevailing downwind direction.
3 Each location has two OSLDs in a vented PVC conduit located approximately three- feet above ground level. The1OSLDs were exchanged quarterly and sent to Landauer for analysis.B. Sample Analysis 3 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 2013. -The analytical procedures used by the laboratoriis:are'-listed in Table B-2.In order-to achieve the'stated objectives, the current program includes the following analyseSi;" .... 1. Concentrations of beta-eritters-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.4. Concentrations of 1-131 in air,n milk,' drinking water and surface water. " 5. Ambient gamma radiation levels at various on-site and off-site environs.
I C. Data Interpretation 3 The radiological and direct radiationadata'collected -prior to CPS becoming operationalwas 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* .6- 3 previous years' operational data for consistency and trending.
Several factors were .important in- the. interpretation of the data: 1. Lower Limit of Detection and Minimum, Detectable Concentration The lower limit of.detection (LLD).was defined as the smallest 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 c oncluding.
that. a blank observation represents a "real" signal.. The LLDwas 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 environmenrtal sample- analysis.2. Net Activity Calculation and ReportingQ of Results Net activity for.a sample was calculated by subtracting background activity from the spample: activity.
Since the REMP measures extremely small changes in, radioactivity in the environment, background variatioRs may result in sample activity being lower than the background activity resulting in a negative number. A minimum detectable concentration (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, well water, fish, sediment and milk 14 nuclides, Be-7, K 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 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.
..The mean and .standard deviation of the results were calculated.
The standard deviation represents the. variability.
of measured results for different samples. rather than single. analysis uncertainty.
-.7-D. Program Exceptions Theexceptions 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-0.133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants", October 1978, and within Radiological Assessment Branch Technical Position, Revision 1, 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 equipmentand other legitimate reasons"...;

...Ambient gamma radiation levels were measured utilizing OSLD (optically stimulated luminescence dosimeters).
Fifty-four OSLD locations were established around the site'. Results of OSLD measurements are listed in Tables C-X.1 to C-X.3, Appendix C.A total of 216 OSLD measurements were made in 2013. The average dose from the in.per ring was ,23.1 mR/quarter.
The average dose from the, outer-ring was 23.2 mR/quarter., The-average dose from the special interest group was 22.9 mR/quarter.
The average dose from the supplemental group was 21.8 mR/quarter.
The quarterly measurements ranged from 18.2 to 27.0 mR/quarter., The. inner ring and outer ring..measurements compared well to the Control Station, CL-1 1, which ranged from 20.5rmR/quarter to 23.3 mR/quarter with an average measurement of 21.5 mR/quarter.
A comparison of the Inner*Ring and Outer Ringdata to the Control Location data indicate that the ambient gamma radiation levels from all the locations were comparable.
The historical ambient gamma radiation data from the control location were plotted along with similar data from the Inner and Outer Ring Locations (Figure. C2,Appendix C).-17.-
D. Land Use Survey A Land Use Survey conducted during the June through September 2013 growing season around the 'Clinton Power Station (CPS) was performed by Environmental Inc. (Midwest Labs) for Exelonjto 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 m2 in each of the sixteen 22 1/2 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.Distance in Kilometers from the CPS Station HVAC Vent Stack Sector ..Residence Garden, Milk Animal 1 N 2 NNE.3. NE 4 ENE 6 ESE.7 SE 8.

{MDC}]. We are required to calculate the MDC using a multiplier of 4.66.6 M D A ... .6A t.2.22'(v ) 18 " 18 -
Where: At = counting time for sample (minutes)P3-=.background:
rate of instrument blank (cpm)2.22 = d!m/pCi or: 2.22 x 106 dpm/pCi v = volume or mass of sample analyzed y = chemical yield E = efficiency of the: counter The formulas for calculating the activity, uncertainty and MDC are contained in the software of the counting equipment.
For the gamma system, when the new detector number 08 was added to the system in January 2012, the default value.of 3.29 was used to calculated the MDCs on detector 08. The activity and uncertaintywere not affected.
The multiplier has been changed from 3.29 to the required 4.66.When the MDCs are recalculated using 4.66, the MDC values will increase by 41.6%. The greatest impact will be on the short-lived nuclides which have an LLD requirement, e.g. 1-131, Ba-140 and La-140. Which means there could be some missed LLDs which will be identified in the Errata Data Appendix tablle of the 2013 annual report. This.is not a reportable issue for the NRC. There is also the possibility that naturally produced nuclides that Were detected would become a non-detect, e.g Th-228, Th-230, etc.F. Summary of Results -Inter-Laboratory Comparison Program The primary laboratory 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 Analytics Inc., Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria: 1.- 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.-19.-
/I 2. ERA Evaluation Criteria" 'ERA's evaluation report provides 'an acceptance range for control and warning limits with associated flag ývalues. 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 3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.TheMAPEP 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 fesult'falls-in the range from'+/- 20%'to +/- 30% of the reference value (i.e., 20% -1 bias <:' 30%)'. If the bias' is greater than 30%, the results:,are deemfed not acceptable.
For the TBE laboratory, 178 out of 185 ana lyses performed met the specified acceptance criteria.
Seven analyses (Sr-89,and Sr-90 in milk, Co-57, Zn-65 and Sr-90 in soil, Cs-1 34 in air particulate and Sr-90 in I vegetation
[two low warning in-a' row]) did not meet the specified acceptance criteria; or internal QA requirements for.the following reason: 1. Teledyne Brown Engineering's Analytjics September 2013 Sr-89 in I milk result of 63.9 pCi/L was.lower than the known value of 96.0 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample. Client samples for the associated time I period were evaluated and no client samples were affected by this'failure.
NCR'13-15 2. Teledyne Brown Engineerng's Analytics Se r r i., ~ .n tc. September2.2013 Sr-90 in milk result of 8.88 pCi/L was lower than the known value of 13.2 pCi/L.. The failure was a result of analyst error.and was specific to the Analytics'sample.
Client-samples for the. associated time period were evaluated and no client samples were affected by this failure. NCR,13-15 I
: 3. & 4.Teledyne Brown Engineering's MAPEP September 2013 Co-57 and Zn-65 in soil were evaluated as failing the false positive test.While MAPEP evaluated the results as failures, the gamma software listed the-,results as non identified nuclides.
The two nuclides would never have been reported as detected nuclides to a client. MAPEP does not allow laboratories to put in qualifiers for the submitted data nor "less than" results. MAPEP evaluates results based on the relationship between the activity and the uncertainty.
MAPEP spiked the soil sample with an extremely large concentration of Eu-1 52, which was identified by the gamma software as an interfering nuclide, resulting in forced activity results that were evaluated by MAPEP as detected Co-57 and Zn-65. No client samples were affected by these failures.
NCR 13-14 5. Teledyne Brown Engineering's MAPEP September 2013 Sr-90 in soil result of 664 Bq/kg was highler than the known value of 460 Bq/kg, exceeding the upper control limit of 598 Bq/kg. An incorrect Sr-90&result was entered'into the.:MAPEP database.
The correct Sr-90 activity of 322 Bq/kg would have been evaluated as acceptable with Warning. No client samples were affected by this failure. NCR 13-14 6.. Teledyne Brown.Engineering's MAPEP September 2013 Cs-1 34 in air particulate activity of -0.570 Bq/sample was, evaluated as a failed false positive test, based on MAPEP's .evaluation of the result as a significant negative value at 3 standard deviations.
A negative number would never have been reported as a detected nuclide to a client, therefore no client samples were affected by this failure.NCR.*", ..314 .-*. ' ..7_ Teledyne Brown Engineering's MAPEP September 2013 Sr-90 in yegetation result was !nvestigated due to :two 10w warnings in a row. It appears the September sample was double spiked with carrier, resutting in~a low activity.
With a recovery of around 50%lower, the Sr-90 result-would have fallen within the acceptance range. -No clienttsampleswere affected by this issue. NCR 13-14 For the EIML laboratory, 89 of 92 analyses met the specified acceptance criteria.
Three analyses (AP -Gross Alpha, Soil -Sr-90 and Co-57) did not meet the specified acceptance criteria for the following reasons: 1. Environmental Inc., Midwest Laboratory's MAPEP February 2013 air particulate gross alpha result of 0.14 Bq/total sample was lower than the known value of 1.20 Bq/total sampleexceeding the lower control limit of 0.36 Bq/total sample. -The filter was recounted overnight.
No significant activity could be detected.-.21-
: 2. Environmental Inc., Midwest Laboratory's MAPEP February 2013 1 soil Co-57 result of 408.40 Bq/kg was lower than the known value of 628.0 .Bq/kg, exceeding the lower control limit of 440.0 Bq/kg.The, sample was reanalyzed using additional fuming nitric ,separations.
The reanalysis result, of 574.4 fell within the control limits.3. Environmental Inc., Midwest Laboratory,'s MAPEP August 2013 soil Co-57 result of 699.60 Bq/kg was higher than the known value of 0.00 Bq/kg, exceeding the upper control limit of 5.00 Bq/kg.Interference from Eu-152' resulted in misidentification of Co-57. I The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.V. References

: 1. Summary and Conclusions In 2006, Exelon instituted a comprehensive program to evaluate the impact of station operations on groundwater and surface water in the vicinity of Clinton Power Station (CPS). This evaluation involved numerous station personnel and contractor support personnel.
This report covers groundwater and surface water samples, collected outside of the Licensee required Off-Site Dose Calculation Manual (ODCM) requirements, both on and off station property in 2013. During that time period, 240 analyses were performed on 108 samples from 32 locations.
The monitoring was conducted in four phases.In assessing all the data gathered for this report, it was concluded that the operation of CPS had no adverse radiological impact on the environment, and there are no known active releases into the groundwater or surface water at CPS. No program changes occurred during the sampling year of 2013.Gamma-emitting radionuclides associated with -licensed plant operations were not detected at concentrations greater than their, respective Lower Limits of Detection (LLDs) as specified in NUREG-1 302 in any of the groundwater or surface water samples. In the case of tritium, Exelon specified that the independent laboratory.
achieve a lower limit of detection
: 10. times lower than that required by the United States Environmental Protection Agency (USEPA)regulation.
Strontium-89 was not detected many 'samples above, the" LLD of 10 pCi/L.Strontium-90 was not detected in any samples above the LLD of 1 pCi/L.Tritium was not detected in any .ofthe groundwater, surface water, or* precipitation water samples at concentrations greater than the United States'Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission Reporting Limit) of 20,000 pCi/L. Background levels ,of tritium were detected -at iconcentrations greater than-the self-imposed LLD of 200 pCi/L in 3 of.17 groundwater monitoring locations.
The tritium concentrations ranged from 198 +/- 122 pCi/L to 348 + 141 pCi/L. Tritium was not detected in any'sUrface water or precipitation water.Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the third quarter of sampling in 2013. Gross Alpha (dissolved) was detected in two of the 17 groundwater locations.
The concentrations ranged from 2.2 to 2.5 pCi/L. Gross Alpha (suspended) was not detected at any of the groundwater locations.
Gross Beta (dissolved) was detected in 15 of 17 groundwater locations.
The concentrations ranged from 2.2 to 10.9 pCi/L. Gross Beta (suspended) was not detected in any of the groundwater locations.
Hard-To-Detect analyses were performed on two groundwater locations to establish background levels. The analyses included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235 and U-238. All hard-to-detect nuclides were not detected at concentrations greater than their respective MDCs.I!I i I I I I I I I I I I I I1. Introduction The Clinton Power Station (CPS),.consisting of one approximately 1,140 MW gross electrical power output boiling water reactor is located in Harp Township, DeWitt County, Illinois.
CPS is owned and operated by Exelon 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 Exelon. 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.
This report covers those analyses performed by Teledyne Brown Engineering (TBE) on samples collected in 2013.A. Objectives of the Radiological Groundwater Protection Program (RGPP)The long-term objectives of the RGPP are as follows: 1. Identify suitable locations to monitor and evaluate potential impacts from station operations before significant radiological impact to the environment and potential drinking water sources.2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up-to-date knowledge of flow patterns on the surface and shallow subsurface.
: 3. Perform routine water sampling and radiological analysis of water from selected locations.
: 4. Report new leaks, spills, or other detections with potential radiological significance to stakeholders in a timely manner.5. Regularly assess analytical results to identify adverse trends.6. Take necessary corrective actions to protect groundwater resources.
B. Implementation of the Objectives The objectives identified have been implemented at Clinton Power Station as discussed below:
I I Exelon and its consultantidentified locations as described in the Phase 1 study. Phase 1 studies were conducted by Connestoga Rovers and Associates (CRA) and the results and conclusions were made available to state and federal regulators as well as the public-in station -specific reports.2. The Clinton Power Station reports describe the local hydrogeologic regime. Periodically, the flow patterns on the surface and shallow subsurface are updated based on ongoing measurements.
3: Clinton Power Station will continue to perform routine sampling and N radiological analysis of water from selected locations.
: 4. ' Clinton Power Station has implemented new'procedures to identify and report new leaks, spiils,-or other:detections with potential radiological'significance in a timely manner.5. Clinton Power Station staff and consulting hydrogeologist assess analytical results on an ongoing basis to identify adverse trends.C. Program'Description
-1.' Sample Collection
" Sample locations-can be found in Table A-1 and Figures A-1 and;A-2, Appendix A. I Groundwater, Surface Water and Precipitation Water 3 Samples of water are collected, rmahaged, transported and analyzed in accordance with approved procedures following*regulatory methods. 'Groundwater, surfakcewater, -and precipitation water are collected. -Sample locations; sample 'collection frequenhies and analytical frequencies are contr6lled-in accordance with approved station procedures.
Contractor and/or station [personnel are trained in the'collection, preservation management, and shipment of samples; as well as in documentation of sampling events. Analytical laboratories are subject to internal quality assurance programs and inter-laboratory cross-check programs, as well as nuclear industry audits. Station personnel review-and evaluate all analytical data deliverables after initial review by the contractor.
Analytical data results are.'reviewed by both station personnel and I an independent hydrogeologistfor adverse trefids or. changes to I I hydrogeologic conditions.
D. Characteristics of Tritium'(H-3)
Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen.
The most common form of tritium is tritium oxide, which is also called "tritiated water." The chemical properties of tritium are essentially those of ordinary hydrogen.Tritiated water behaves the same as ordinary water in both the e.nvironment and-:the body.. Tritiumcan be taken into the body by drinking water, breathing air, eating food, or absorption,through skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Tritium is excreted primarily through urine with a-clearance rate characterized by an effective biological half-life of about 14 days. Within one month or so after ingestion, essentially all tritium is cleared. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the. body for a longer period.Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules.
Tritium is also produced, during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotopes lithium-7 and/or boron-10 are activated to produce tritium. Like normal water, tritiated water is colorless and odorless.
Tritiated ,water behaves chemically and physically like non-tritiated water in the subsurface, and therefore tritiated water will travel at the same velocity as the average groundwater velocity.Tritium has a half-life of approximately 12.3 years. It decays spontaneously to helium-3 (3he).-This, radioactive decay releases a beta..particle (Iow-energy electron).
The radioactive decay of tritium is the;source of the health risk from exposure to tritium,.
Tritium is one of the least dangerous radionuclides:
because it emitsvery weak beta radiation , ,and leaves the body relatively quickly..
Since-tritiumis almost always found.as, water, it goes directly into soft tissues and organs. The associated dose. to these tissues is generally uniform and is dependent on the water-contentz of the specific tissue.Ill. Program Description A. Sample Analysis This section describes the general analytical methodologies used by TBE and EIML to analyze the environmental samples, for radioactivity for the-Clinton Power Station RGPP in 2013.In order to achieve the stated objectives, the current program includes the following analyses: 1. Concentrations of gamma emitters in groundwater and surface water.2. Concentrations of strontium in groundwater.
: 3. Concentrations of tritium in groundwater, surface water and precipitation water.4. Concentrations of gross alpha and gross beta in groundwater.
: 5. Concentrations of Am-241 in groundwater..
!6. Con.entrations of Cm?42 and.Cm-243/244.in groundwater.
: 7. Concentrations of Pu-238 and Pu-239/240 in groundwater.
: 8. Concentrations of U-234, U-235 and U-238 in groundwater.
: 9. Concenrtrations of Fe-55 in groundwater.
: 10. Concentrations of Ni-63 in groundwater.
U B. Data Interpetation The radiological data collected prior to .Clinton Power Station becoming operational were used as a baseline with which thesepoperational data were compared.
For the purpose of this report,: Clinton Power Station was considered operational at initial criticality.
Several factors were important in the interpretation of the data: 3 1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is specified by federal regulation as a minimum sensitivity value that must be.achieved routinely by the analytical parameter.
: 2. Laboratory Measurements The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the I measurement value.....
Statistically, the exact value of a measurement is expressed as a range with a stated level of confidence.
The convention is to report results with a 95% level of confidence.
The uncertainty comes from calibration standards, sample.volume or weight measurements, sampling uncertainty and other factors. Exelon reports the uncertainty of a measurement created by statistical process (counting error) aswell as all sources of error (Total Propagated Uncertainty or TPU). Each result has two values calculated.
Exelon reports the TPU by following the result with plus or minus +/- the estimated sample standard deviation, as TPU, that is obtained by propagating all sources of analytical uncertainty in measurements.
Analytical uncertainties are reported;atthe.95%
confidence level in this report for reporting consistency with the AREOR.Gamma spectroscopy results for eachtype'of sample were grouped as follows: For groundwater and surface water 13 nuclides, Be-7, K-40, Mn-54, Co-58, Fe-59, Co-60', Zn-65, Nb-95, Zr-95, Cs-134, Cs-1 37, Ba-1 40 and La-14.0 were reported..
C. Background Analysis A pre-operational radiological environmental monitoring program (pre-operational REMP) was conducted to establish background radioactivity levels prior to operation of the Station. The environmental media sampled andan'alyzed during the pre-bperatidnal REMP were atmospheric
'' radiation', fafll-out, domestic water,:surface water, mari:ne life, milk, and vegetation.
The results of the monitoring were detailed in the report entitled, E&#xfd;nvirohmental Radiological Monitoring' for Clinton Power Nuclear Power Station, Illinois Power Company, Annb~al Report 1987, May 1988.The pre-operational REMP contained analytical results from samples collected from the surface water and groundwater.
: 1. Background-Concentrations of Tritium The purpose of the following discussion is to summarize background measurement~s'of tritium in-various media performed by others.
i a. Tritium Production, Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man-made) sources. In the upper atmosphere, "Cosmogenic" tritium is produced from the bombardment of stable nuclides and combines with oxygen to form tritiated water, which will then enter the hydrologic cycle. Below ground, "lithogenic" tritium is produced by the bombardment of natural lithium present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant uranium and thorium- Lithogenic production of tritium is usually negligible compared to other sources due to I the limited abundance of lithium in rock. The lithogenic tritium is introduced directly to groundwater.
A major anthropogenic source of tritium and strontium-90 I Comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased significantly during the 1950s and early 1960s, and later with additional testing, resultingiii the release of significant amounts of tritium to the atmosphere.
The Canadian heavy water nuclear power reactors, other commercial power reactors, nuclear research and weapons production continue to influence tritium concentrations in the environment.
: b. Precipitation Data Precipitation samples are routinely collected at stations i around the worldfor the analysis of tritium and other radionuclides.
Two publicly available databases that provide tritium concentrations in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet database.
GNIP provides tritium precipitation concentration data for samples collected world wide from 1960 to 2006.RadNet provides tritium precipitation concentration data for samples collected at stations through out the U.S. from 1960 up to and including 2006. Based on GNIP data for sample stations located in the U.S. Midwest, tritium concentrations peaked around 1963. This peak, which approached 10,000 pCi/L for some stations, coincided with the atmospheric testing of thermonuclear weapons: Tritium. concentrations in surface water showed a sharp decline up until 1975,-followed; by a gradual decline. since that time. Tritium I concentrations in Midwest precipitation have typically been i below 100 pCi/L since around 1980. Tritium concentrations in wells may still be above the 200 pCi/L detection limit from the external causes described above.c. Surface Water Data Tritium concentrations are. routinely measured in Clinton Lake.According to the USEPA, surface water data typically has an uncertainty
+/-70 to, 100 pCi/L 95% confidence bound on each given: measurement., Therefore, the typical background..data provided may be subject to measurement
* uncertainty of approximately:
+/-70 to 100 pCi/L.The radio-analytical laboratory is counting tritium results to an Exelon specified LLD-of 200 pCi/L. Typically, the lowest-positive measurement will be reported within a range of 40 --240 pCi/L or 140 +/- 100 pCi/L. Clearly, these sample results cannot-be distinguished as different from background at this.* concqntration.

-Baseline samples were, collected from. off-site wells during four (4)phasesat the station. Analytical results are discussed below. No-.9-I I anomalies were noted during the year.Tritium Samples from 17 locations were analyzed for tritium activity (Table U B-4.1 Appendix B).' Tritium values ranged .from below the Exelon imposed LLD of:198 pCi/I to 348 pCi/I.Strontium Strontium-89 was not detected in any of the 17. samples analyzed and the required LLD of 10 pCi/L was met. Strontium-90 was also not detected, in any of the 17 samplesanalyzed and the required LLD of 1 pCi/L was met. (Table B-1.1 Appendix B).Gross Alpha and Gross Beta (dissolved and suspended)
Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed.
on groundwater samples during the third quarter of sampling in 2013. Gross Alpha (dissolved):was detected in twoWof the: 17 groundwater locations.
The concentrations ranged from 2.2 to.2.5 pCi/L. Gross Alpha (suspended) was not detected at any of the groundwater locations.
Gross Beta (dissolved) was, detected in 15 of 17 groundwater locations.
The concentrations ranged from 2.2 to 10.9 pCi/L.Gross Beta (suspended) was not detected in any of the groundwater locations (Table B-1.1 Appendix B).Gamma Emitters, -.Naturally occurring K-40 was detect in two samples. The concentrations ranged from 32 to 62 pCi/L. No other gamma I emitting nuclides were detected (Table B-1.2, Appendix B).Hard-To-Detect I Hard-To-Detect analyses were performed on two groundwater locations to establish background levels. The analyses included Fe-55, Ni-63, Am-241, Cm-'242, Cm-243/244, Pu-238, Pu-239/240, U-234,U-235 and U-238. All hard-to-detect nuclides were not detected at concentrations greater than their.respective MDCs. U Occasionally, the isotopes of U-234 and U-238 are detected at low'levels and indistinguishable from background (Table B-1.3 Appendix B). I I D. Surface Water Results:;Surface Water Baseline samples were collected from on-site surface waters during four-(4) phases at the station. Analytical results are discussed below.
