Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the LaSalle County Station (LSCS) by Exelon covers the period 1 January 2014 through 31 December 2014. During that time period, 1,407 analyses were performed on 1,393 samples. In assessing all the data gathered for this report and comparing these results with preoperational data, it was concluded that the operation of LSCS had no adverse radiological impact on the environment.

Surface water samples were analyzed for concentrations of gross beta, tritium and gamma emitting nuclides. Ground/well water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No fission or activation products were detected. Gross beta and tritium activities detected were consistent with those detected in previous years.

Fish (commercially and recreationally important species) and sediment samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected in fish. Cs-137 was detected in both samples at control location L-21. Occasionally Cs-i 37 is detected at very low levels (just above LLD) and is not distinguishable from background levels.

Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. 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 activity for 1-131.

Cow milk samples were not analyzed in 2014 for concentrations of 1-131 and gamma emitting nuclides as this dairy herd was sold prior to the first sample in 2014.

Food product samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected.

Environmental gamma radiation measurements were performed quarterly using Optically Stimulated Luminescence Dosimeters (OSLD). Beginning in the first quarter of 2012, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry were deployed and Thermo-luminescent Dosimetry (TLD) were discontinued. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation).

Introduction The LaSalle County Station (LSCS), consists of two boiling water reactors, each rated for 3,546 MWt. Both units are owned and operated by Exelon Corporation and are located in LaSalle County, Illinois. Unit I went critical on 16 March 1982. Unit 2 went critical on 02 December 1983. The site is located in northern Illinois, approximately 75 miles southwest of Chicago, Illinois.

A Radiological Environmental Monitoring Program (REMP) for LSCS was initiated in 1982 (the preoperational period for most media covers the periods 1 January 1979 through 26 December 1981 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 I January 2014 through 31 December 2014.

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 (ii any) on man and the environment.

Ill. Program Description A. Sample Collection Samples for the LSCS REMP were collected for Exelon Nuclear by Environmental Inc. (Midwest Labs). This section describes the general Page 7 of 178

collection methods used by Environmental Inc. (Midwest Labs) to obtain environmental samples for the LSCS REMP in 2014. Sample locations and descriptions can be found in Tables BI and B2, and Figures Bi through B4, Appendix B.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, ground/well water, fish, and sediment. Two gallon water samples were collected weekly from two surface water locations (L-21 and L-40) and composited for monthly and quarterly required analyses. Control location was L-21. Two ground/well water locations (L-27 and L-28) were also grab sampled quarterly. All samples were collected via grab sample. The samples were then transferred to new unused plastic containers. Both the grab container and the sample containers were rinsed with source water prior to actual sample collection. Fish samples were collected semiannually at three locations, L-34, L-35 and L-36 (Control). Sediment samples composed of recently deposited substrate were collected at three locations semiannually, L-21 (Control), L-40 and L-41.

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of airborne particulate and iodine. Airborne particulate and iodine samples were collected and analyzed weekly at nine locations (L-01, L-03, L-04, L-05, L-06, L-07, L-08, L-i0 and L-1 1).

The control location was L-10. Airborne particulate and iodine samples were obtained at each location, using a vacuum pump to pull air through a glass fiber particulate filter and iodine cartridge. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The particulate filters and iodine cartridges were replaced weekly and sent to the laboratory for analysis.

Terrestrial Environment The terrestrial environment was evaluated by performing radiological analyses on samples of milk and food product. Samples are typically collected biweekly at one milk location (L-42) from May through October, and monthly from November through April. The control location was L-42.

All samples, when available, were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory.

Food products were collected annually in September at five locations fL-Quad C, L-Quad I, L-Quad 2, L-Quad 3 and L-Quad 4). The control Page 8 of 178

location was L-Quad C. Various types of samples were collected and placed in new unused plastic bags, and sent to the laboratory for analysis.

Ambient Gamma Radiation Beginning in the first quarter of 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.

This change may cause step changes in readings, up or down, depending on site characteristics. However, the relative comparison to control locations remains valid. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation).

Each location consisted of 2 OSLD sets. The OSLDs were exchanged quarterly and sent to Landauer for analysis. The OSLD locations were placed on and around the LSCS site as follows:

An inner ring consisting of 16 locations (L-J01, L-102, L-103, L-104, L-105, L-106, L-107, L-108, L-109, L-110, L-111B, L-112, L-113A, L-114, L-1 15 and L-1 16) near and within the site perimeter representing fence post doses (i.e., at locations where the doses will be potentially greater than maximum annual offsite doses) from LSCS release.

An outer ring consisting of 16 locations (L-201, L-202, L-203, L-204, L-205, L-206, L-207, L-208, L-209, L-210, L-21 1, L-212, L-213, L-214, L-215 and L-216) extending to approximately 5 miles from the site designed to measure possible exposures to nearby population.

An other set consisting of eight locations (L-01, L-03, L-04, L-05, L-06, L-07, L-08 and L-1 1).

The balance of one location (L-10) representing the control area.

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 the sixteen 22 1/2 degree sectors around the site, where estimated annual dose from LSCS, if any, would be most sign ifi cant;

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

Page 9 of 178

4. And near the closest dwelling to the vents in the prevailing downwind direction.

(Two OSLDs were placed at each location approximately six feet above ground level.)

B. Sample Analysis This section describes the general analytical methodologies used by TEE and Environmental Inc. (Midwest Labs) to analyze the environmental samples for radioactivity for the LSCS REMP in 2014. The analytical procedures used by the laboratories are listed in Table E-2.

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

1. Concentrations of beta emitters in surface water and air particulates.

2. Concentrations of gamma emitters in ground/well and surface water, air particulates, milk, fish, sediment and vegetation.

3. Concentrations of tritium in ground/well and surface water.

4. Concentrations of 1-131 in air and milk.

5. Ambient gamma radiation levels at various site environs.

C. Data Interpretation The radiological and direct radiation data collected prior to LaSalle County Station becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, LaSalle County Station 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:

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is 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 concluding that a blank observation represents a real signal. The LLD is intended as a before the fact (a priori) estimate of a system (including instrumentation, Page 10 of 178

procedure and sample type) and not as an after the fact (a posteriori) criteria for the presence of activity. All analyses were designed to achieve the required LSCS detection capabilities for environmental sample analysis.

The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

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 effecting 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 food product 12 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, I-131, Cs-134, Cs-137, Ba-140 and La-140 were reported.

For ground/well water, fish, sediment, air particulate and milk II nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, Cs-i 34, Cs-I 37, Ba-140 and La-i 40 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.

D. Program Exceptions For 2014, the LSCS REMP had a sample recovery rate of 97.8%. Sample anomalies and missed samples are listed in the tables below:

E. Program Changes A new air monitoring location, L-1 IA, was installed in mid-December of 2014 and is currently collecting preliminary data, but is not operational at this time.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were taken weekly and composited monthly at two locations (L-21 and L-40). Of these locations only L-40 located downstream, could be affected by LaSalles effluent releases. The following analyses were performed:

Gross Beta Samples from all locations were analyzed for concentrations of gross beta (Table Cl.1, Appendix C). Gross beta was detected in all 24 samples with a range of 4.2 to 11.1 pCi/I. Concentrations detected were consistent with those detected in previous years Page 14 of 178

(Figure Ci, Appendix C). The required LLD was met.

Tritium Quarterly composites of weekly collections were analyzed for tritium activity (Table Cl.2, Appendix C). Tritium was detected in four of eight samples. The concentrations ranged from 327 to 470 pCi/I. Concentrations detected were consistent with those detected in previous years (Figure C2, Appendix C). The 2000 pCi/L OCDM and contractually requited 200 pCiIL LLDs were met.

Gamma Spectrometry Samples from both locations were analyzed for gamma emitting nuclides (Table Cl.3, Appendix C). No nuclides were detected, and all requited LLDs were met.

2. Ground/Well Water Quarterly grab samples were collected at two locations (L-27 and L-28). Wells 4, 5 and 6 are associated with L-28. L-27 and L-28 well 6 could be affected by LaSalles effluent releases. The following analyses were performed:

Tritiu m Quarterly grab samples from the locations were analyzed for tritium activity (Table Cll.1, Appendix C). No tritium was detected and the 2000 pCi/L OCDM and contractually required 200 pCi/L LLDs were met.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table Cll.2, Appendix C). No nuclides were detected, and all required LLDs were met.

3. Fish Fish samples were collected at three locations (L-34, L-35 and L-36) semiannually. Locations L-34 and L-35 could be affected by LaSalles effluent releases. The following analysis was performed:

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

Page 15 of 178

Naturally occurring K-40 was found at all stations and ranged from 2,096 to 4,664 pCi/kg wet. No fission or activation products were found.

4. Sediment Aquatic sediment samples were collected at three locations (L-21, L-40 and L-41) semiannually. Locations L-40 and L-41, located downstream, could be affected by LaSalles effluent releases. The following analysis was performed:

Gamma Spectrometrv Sediment samples from both locations were analyzed for gamma emitting nuclides (Table ClV.1, Appendix C). Nuclides detected were naturally occurring K-40. Potassium-40 was found at all stations and ranged from 13,040 to 19,110 pCi/kg dry. Cesium-137 was detected in two samples. The concentration ranged from 146 to 166 pCi/L. No LaSalle fission or activation products were found.

B. Atmospheric Environment Airborne

a. Air Particulates Continuous air particulate samples were collected from nine locations on a weekly basis. The nine locations were separated into four groups: Group I (onsite) represents locations within the LSCS site boundary (L-03 and L-05),

Group II (near site) represents the locations near the LSCS site (L-01 and L-06), Group Ill (far field) represents the control location at an intermediate distance from LSCS (L-04, L-07, L-08 and L-1 1) and Group IV (Control) represents the control location at a remote distance (L-10).

The following analyses were performed:

Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table CV.1 and CV.2, Appendix C).

Detectable gross beta activity was observed at all locations.

Comparison of results among the four groups aid in determining the effects, if any, resulting from the operation of LSCS. The results from the OnSite locations (Group I) ranged from 3 to 33 E3 pCi/rn3 with a mean of 18 E3 pCi/rn3. The results from the near site location (Group II) 11 Page 16 of 178

ranged from 5 to 32 E3 pCi/rn3 with a mean of 19 E3 pCi/rn3. The results from the far field locations (Group Ill) ranged from 6 to 31 E-3 pCi/rn3 with a mean of 18 E3 pci/rn3. The results from the Control location (Group IV) ranged from 6 to 29 E3 pCi/rn3 with a mean of 18 E3 pCi/rn3. Comparison of the 2014 air particulate data with previous years data indicate no effects from the operation of LSCS (Figures C3 through C-7, Appendix C). In addition, comparisons of the weekly mean values for 2014 indicate no notable differences among the four groups.

Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table CV.3, Appendix C).

Naturally occurring Be-7 due to cosmic ray activity was detected in 34 of 36 samples. These values ranged from 66 to 155 E3 pCi/rn3. Naturally occurring K-40 was detected in two samples. The concentration ranged from 28 to 31 E3 pCi/rn3. All other nuclides were less than the MDC.

b. Airborne Iodine Continuous air samples were collected from nine locations (L-01, L-03, L-04, L-05, L-06, L-07, L-08, L-1 0 and L-1 1) and analyzed weekly for 1-131 (Table CVl.1, Appendix C). No 1-131 was detected. All required LLDs were met.

2. Terrestrial

a. Milk Samples are typically collected from one location (L-42) biweekly May through October and monthly November through April. The following analyses are typically performed:

Iodine-I 31 Milk samples from the location are typically analyzed for concentrations of 1-131 (Table CVII.1, Appendix C). 1-131 was not analyzed in 2014.

Gamma Spectrometry Milk samples are typically analyzed for concentrations of Page l7of 178

gamma emitting nuclides (Table CVll.2, Appendix C).

Naturally occurring K-40 activity is typically found in all samples. Gamma emitting nuclides were not analyzed in 2014.

b. Food Products Food product samples were collected at five locations (L-Quad C, L-Quad 1, L-Quad 2, L-Quad 3 and L-Quad 4) when available. Four locations, (L-Quad 1, L-Quad 2, L-Quad 3 and L-Quad 4) could be affected by LaSalles effluent releases. The following analysis was performed:

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table CVlll.1, Appendix C). No nuclides were detected, and all required LLDs were met.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Optically Stimulated Luminescence Dosimeters (OSLD). Forty-one OSLD locations were established around the site. Results of OSLD measurements are listed in Tables ClX.1 to CIX.3, Appendix C.

All OSLD measurements were at or below 30 mrem/quarter, with a range of 16.2 to 30.0 mrem/quarter. A comparison of the Inner Ring, Outer Ring, and Other data to the Control Location data, indicate that the ambient gamma radiation levels from the Control Location L-J0 were corn parable.

D. Land Use Survey A Land Use Survey conducted during the August 2014 growing season around the LaSalle County Station (LSCS) was performed by Environmental Inc. (Midwest Labs) for Exelon Nuclear to comply with Radiological Effluent Control 12.5.2 of the LaSalles Offsite Dose Calculation Manual. The purpose of the survey was to document the nearest resident, milk producing animal and garden of greater than 500 ft2 in each of the sixteen 22 % degree sectors around the site. The distance and direction of all locations from the LSCS reactor buildings were positioned using Global Positioning System (GPS) technology. There were no changes required to the LSCS REMP as a result of this survey.

The results of this survey are summarized below:

F. Summary of Results Inter-Laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices (Appendix D). The PE samples, supplied by Analytics Inc., Environmental Resource Associates (ERA) and DOEs 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 laboratory results 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 ERAs evaluation report provides an acceptance range for control and warning limits with associated flag values. ERAs acceptance limits are established per the USEPA, NELAC, state specific PT Page l9of 178

program requirements or ERAs 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 MAPEPs 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%). lIthe bias is greater than 30%, the results are deemed not acceptable.

In reviewing our environmental inter-laboratory crosscheck programs, we identified 1) duplication of efforts on some matrices and isotopes and 2) that we are performing crosscheck samples on some matrices and isotopes that we do not perform for clients. Since the DOE MAPEP is designed to evaluate the ability of analytical facilities to correctly analyze for radiological constituents representative of those at DOE sites, the needed changes were made to the MAPEP program. Therefore, the following isotopes were removed from the MAPEP program:

Soil gamma will be provided by Analytics twice per year, starting in 2015. For 2014, one soil gamma is provided by MAPEP, the 2 soil gamma is provided by Analytics.

AP gamma is currently provided by Analytics.

Water gamma, H-3, Sr-90, uranium, gross alpha and gross beta currently provided by ERA.

MAPEP evaluates non-reported (NR) analyses as failed if they were reported in the previous series.

For the TBE laboratory, 163 out of 169 analyses performed met the specified acceptance criteria. Six analyses (Ni-63, K-40 and 1-131 in water, and two Sr-90s and one Gross Alpha in AP samples) did not meet the specified acceptance criteria for the following reasons:

1. Teledyne Brown Engineerings MAPEP March 2014 Ni-63 in water result of 32.7 +/- 1.69 Bq/L was overlooked when reporting the data Page 20 of 17$

but would have passed the acceptance range of 23.9 44.2 Bq/L.

No client samples were affected by this failure. NCR 14-04

2. Teledyne Brown Engineerings MAPEP March 2014 K-40 in water result of 1.63 +/- 2.49 Bq/L was overlooked when reporting the data but would have passed the false positive test. No client samples were affected by this failure. NCR 14-04

3. Teledyne Brown Engineerings ERA November2014 1-131 in water result of 15.8 pCi/L was lower than the known value of 20.3 pCi/L, failing below the lower acceptance limit of 16.8. The result was evaluated as failed with a found to known ratio of 0.778. No cause could be found for the slightly low result. All ERA 1-131 evaluations since 2004 have been acceptable. No client samples were affected by this failure. NCR 14-08

4. Teledyne Brown Engineerings MAPEP March 2014 Sr-gO in AP result of 0.822 Bq/sample was lower than the known value of 1.18 Bq/sample, falling below the lower acceptance limit of 0.83 Eq/sample. The rerun result was still low, but fell within the lower acceptance range of 0.836. The rerun result was statistically the same number as the original result. No cause could be found for the slightly low results. No client samples were affected by this failure. NCR 14-04

5. Teledyne Brown Engineerings MAPEP September 2014 Sr-90 in AP result of 0.310 Bq/sample was lower than the known value of 0.703 Sq/sample. The gravimetric yield of 117% was very high (we normally see yields of 60% to 70%) and could account for the low activity. No client samples were affected by this failure. NCR 14-09

6. Teledyne Brown Engineerings MAPEP September 2014 Gr-Alpha in AP result of 0.153 Bq/sample was lower than the known value of 0.53 Eq/sample. The AP sample was counted on the wrong side.

The AP was flipped over and recounted with acceptable results.

No client samples were affected by this failure. NCR 14-09 For the EIML laboratory, 85 of 90 analyses met the specified acceptance criteria. Five analyses (Water Pu-238, Pu-239, Fe-55; AP Co-57; Soil Cs134) did not meet the specified acceptance criteria for the following reasons:

Environmental Inc., Midwest Laboratorys MAPEP February 2014 water Pu-238 result of 1.28 Bq/L was higher than the known value of 0.83 Bq/L, exceeding the upper control limit of 1.08 Bq/L. The high bias on the plutonium was traced to contamination from a newly purchased standard. The result of the reanalysis with the Page 21 of 178

new tracer was 0.68 Bq/L, which fell within the acceptance criteria.

Client samples for the associated time period were evaluated, and no client samples were affected by the issue.

2. Environmental Inc., Midwest Laboratorys MAPEP February 2014 water Pu-2391240 result of 0.91 Bq/L was higher than the known value of 0.68 Bq/L, exceeding the upper control limit of 0.88 Bq/L.

The high bias on the plutonium was traced to contamination from a newly purchased standard. The result of reanalysis with the new tracer was 0.66 Bq/L, which fell within the acceptance criteria.

Client samples for the associated time period were evaluated, and no client samples were affected by the issue.

3. Environmental Inc., Midwest Laboratorys MAPEP February 2014 AP Co-57 result of 1.60 +/- 0.05 Eq/total sample failed the false positive test. Interference from the Eu-i 52 resulted in the misidentification of Co-57. The failure was specific to the MAPEP sample. Therefore, there was no impact to client samples as a result of this issue.

4. Environmental Inc., Midwest Laboratorys MAPEP February 2014 soil Cs-i 34 result of 6.10 +/- 1.80 Eq/kg failed the false positive test.

Long sample counting time lead to interference from naturally occurring Bi-214 in the sample matrix with a close spectral energy.

The failure was specific to the MAPEP sample. Therefore, there was no impact to client samples as a result of this issue.

5. Environmental Inc., Midwest Laboratorys MAPEP August 2014 water Fe-55 result of 55.10 +/- 14.80 Bq/L was higher than the known value of 31.50 Bq/L, exceeding the upper control limit of 41.00 BqIL. The result of the reanalysis of Fe-55 was 32.63 +/-

16.30 BqIL, which fell within the acceptance criteria. Client samples for the associated time period were evaluated, and no client samples were affected by the issue.

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

INTRODUCTION LaSalle County Station, a two-unit BWR, is located near Marseilles, Illinois in LaSalle County, 3.5 miles south of the Illinois River. Both units are rated at 3546 MWt. Unit 1 loaded fuel in March 1982. Unit 2 loaded fuel in late December 1983. The Station is designed to keep releases to the environment at levels below those specified in the regulations.

Liquid effluents, although no longer released from LaSalle County Station, were designed to be released to the Illinois River in controlled batches after radioassay of each batch. Gaseous effluents are released to the atmosphere after delay allowing time for short-lived (noble) gases to decay. Releases to the atmosphere are sampled and analyzed on a routine basis. The gaseous effluent samples are analyzed for particulate, iodine, noble gas, and tritium activity. The particulate and iodine sample results are obtained from continuously collected composite samples. The noble gas and tritium sample results are obtained from routine grab samples. The results of effluent analyses are summarized on a monthly basis and reported to the Nuclear Regulatory Commission as required per Technical Specifications. Airborne concentrations of noble gases, tritium, I-131, and particulate radioactivity in offsite areas are calculated using effluent and meteorological data.

Environmental monitoring is conducted by sampling at indicator and control (background) locations in the vicinity of LaSalle County Station to measure changes in radiation or radioactivity levels that may be attributable to station operations. If significant changes attributable to LaSalle County Station are measured, these changes are correlated with effluent releases. External gamma radiation exposure from noble gases and internal dose from 1-131 in milk are the critical pathways at this site; however, an environmental monitoring program is conducted which also includes these and many other pathways which are less significant in terms of radiation protection.

SUMMARY

Gaseous effluents for the period contributed to only a small fraction of the LaSalle County Station Radiological Effluent Controls Limits. Liquid effluents had no contribution to offsite dose, as no liquid radioactive discharges were conducted. Calculations of environmental concentrations based on effluent, Illinois River flow, and meteorological data for the period indicate that consumption by the public of radionuclides attributable to LaSalle County Station does not exceed regulatory limits. Radiation exposure from radionuclides released to the atmosphere represented the critical pathway for the period with a maximum individual total dose estimated to be 1.67E+00 mrem for the year, where a shielding factor of 0.7 and an occupancy factor of 0.95 are assumed for the nearest resident. The assessment of radiation doses is performed in accordance with the Offsite Dose Calculation Manual (ODCM), specifically, a comparison of preoperational studies with operational controls or with previous environmental surveillance reports and an assessment of the observed impacts of the plant operation on the environment. Control locations are basis for preoperational data. The results of analysis confirm that the station is operating in compliance with JOCFR5O Appendix I, IOCFR2O and 4OCFR19O.

1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere Measured concentrations of noble gases, radioiodine, and particulate radioactivity released to the atmosphere during the year, are listed in Table 1.1-1. A total of 3.87E+03 curies of fission and activation gases were released with an average release rate of 1 .23E+02 pCi/sec.

A total of 1.87E-01 curies 011-131 were released during the year with an average release rate of 5.94E-03 pCi/sec.

A total of 3.59E-02 curies of beta-gamma emitters were released as airborne particulate matter with an average release rate of 1 .14E-03 pCi/sec. Alpha-emitting radionuclides were below the lower limit of detection (LLD). Carbon-14 released in 2014 was calculated separately with a total of 3.35E+01 curies released with an average release rate of I .06E÷00 pCi/sec.

A total of I .82E+01 curies of tritium were released with an average release rate of 5.76E-01 pCi/sec.

1.2 Liquids Released to Illinois River There were no liquid batch releases in 2014. Continuous release path activity was below applicable Lower Limits of Detection.

2.0 SOLID RADIOACTIVE WASTE Solid radioactive wastes were shipped by truck to a disposal facility or to a waste processor. For further detail, refer the LaSalle 2014 Annual Radioactive Effluent Release Report (ARERR). This report was submitted 1st to the USNRC by the required date of May 2014.

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways Table 3.1-1 summarizes the doses resulting from releases of airborne radioactivity via the different exposure pathways.

3 Page 82 of 178

3.1.1 Noble Gases 3.1.1.1 Gamma Dose Rates Unit I and Unit 2 gaseous releases at LaSalle County Station are reported as Unit I releases due to a single station vent stack (SVS) release point. Offsite Gamma air and whole body dose rates are shown in Table 3.1-1 and were calculated based on measured release rates, isotopic composition of the noble gases and average meteorological data for the period.

Doses based on concurrent meteorological data are shown in Table 3.4-1. Based on measured effluents and meteorological data, the maximum total body dose to an individual would be 3.19E-02 mrem (Table 3.1-1) for the year, with an occupancy factor of 0.95 and a shielding factor of 0.7 included. The maximum total body dose based on measured effluents and concurrent meteorological data would be 2.22E-02 mrem (Table 3.4-1).

The maximum gamma air dose was 4.78E-02 mrad from Table 3.1-1, and the maximum gamma air dose from concurrent meterorological data was 5.38E-03 mrad (Table 3.4-I).

3.1.1.2 Beta Air and Skin Dose Rates The range of beta particles in air is relatively small (on the order of a few meters or less);

consequently, plumes of gaseous effluents may be considered infinite for purpose of calculating the dose from beta radiation incident on the skin.

However, the actual dose to sensitive skin tissues is difficult to calculate due to the effect of the beta particle energies, thickness of inert skin and clothing covering sensitive tissues. For purposes of this report the skin is taken to have a thickness of 7.0 mg/cm2 and an occupancy factor of 1.0 is used. The skin dose (from beta and gamma radiation) for the year was 5.38E-02 mrem from Table 3.1-1, and the skin dose from concurrent meteorological data was 5.57E-03 mrem (Table 4

3.4-1). The maximum offsite beta dose for the year was 2.22E-03 mrad from Table 3.1-1, and the maximum offsite beta dose from concurrent meteorological data was I .93E-03 mrad (Table 3.4-1).

3.1.2 Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. The radioiodine, 1-131, released during routing operation of the plant, may be made available to man resulting in a dose to the thyroid.

The principal pathway of interest for this radionuclide is ingestion of radioiodine in milk.

3.1.2.1 Dose to Thyroid The hypothetical thyroid dose to a maximum exposed individual living near the station via ingestion of milk was calculated. The radionuclide considered was 1-131 and the source of milk was taken to be the nearest dairy farm with the cows pastured from May through October. The maximum thyroid does due to 1-131 was 9.13E-O1 mrem for the year.

3.2 Liquid Effluent Pathways The three principal pathways through the aquatic environment for potential doses to man from liquid waste are ingestion of potable water, eating aquatic foods, and exposure while on the shoreline.

Not all of these pathways are significant or applicable at a given time but a reasonable approximation of the dose can be made by adjusting the dose formula for season of the year or type and degree of use of the aquatic environment. NRC developed equations* were used to calculate the doses to the whole body, lower gastro-intestinal tracts, thyroid, bone and skin; specific parameters for use in the equations are given in the Offsite Dose Calculation Manual. The maximum whole body dose was O.OOE+OO mrem and organ dose was O.OOE+OO for the year mrem (Table 3.2-1).

Station did not exceed these limits as shown in Table 3.1-1 and Table 3.2-1 (based on annual average meteorological data), and as shown in Table 3.3-1:

The Radiological Effluent Technical Standards fRETS) limits on dose or dose commitment to an individual due to radioactive materials in liquid effluents from each reactor unit (1.5 mrem to the whole body or 5 mrem to any organ during any calendar year; 3 mrem to the whole body or 10 mrem to any organ during the calendar year).

• The RETS limits on air dose in noble gases released in gaseous effluents to a member of the public from each reactor unit (5 mrad for gamma radiation or 10 mrad for beta radiation during any calendar quarter; 10 mrads for gamma radiation or 20 mrad for beta radiation during a calendar year).

• The RETS limits on dose to a member of the public due to iodine-131, iodine-133, tritium and radionuclides in particulate form with half-lives greater than eight days in gaseous effluents released from each reactor unit (7.5 mrem to any organ during any calendar quarter; 15 mrem to any organ during any calendar year).

• The 10CFR2O limit on Total Effective Dose Equivalent to individual members of the public (100 mrem).

4.0 SITE METEOROLOGY A summary of the site meteorological measurements taken during each calendar quarter of the year is given in Appendix F. The data are presented as cumulative joint frequency distributions of the wind direction for the 375 level and wind speed class by atmospheric stability class determined from the temperature difference between the 375 and 33 levels. Data recovery for these measurements was 99.9% during 2014.
