The REMP is a requirement of the Fort Calhoun Station~(FCS) operating license. It was initiated prior to plant operation in 1973.*The main purpose of the REMP is to ensure public safety by monitoring plant discharges and assessing the effect, if any, of plant operations, on the environment.

Samples are collected that would account for various exposure pathways such as*ingestion, inhalation, adsorption and direct exposure.

Samples collected on a regular* basis include: air, surface water, ground water, milk, vegetation, fish, sediment, and food crops. Direct radiation is measured by thermoluminescent dosimeters (TLDs).These samples and TLDs are sent to an independent vendor laboratory for analysis.*The vendor uses analytical methods that are sensitive enough to detect a level of*activity far below that which would be considered harmful. Locations for sample*collection are based on radiological and meteorological data from the Annual Effluent Release Report and information obtained from the Environmental Land Use Survey.*Most samples, particularly indicator samples, are collected in a circular area within a* five-mile radius of plant containment. (However, control locations are usually outside of five miles.) This circle is divided into sixteen equal sectors, each assigned an identification letter "A" through "R" (note: letters "I" and "0" are not used, as they may be*mistaken for the numbers "1" and "0"). Sector "A" is centered on North or zero degrees.*Sectors are also given directional labels such as "West-Southwest" ("WSW"). Sample*locations are listed by number along with their respective distances and direction from plant containment, in the Offsite Dose Calculation Manual (ODCM).*When assessing sample results, data from indicator locations (those most likely to be* effected by plant operations) are compared to those from control locations (those least or not likely to be effected).

Results from an indicator location which were significantly higher than those from a control location, could indicate a plant-attributable effect, and*could require additional investigation.

0*The results of the sample analyses, as required by the FCS Offsite Dose Calculation Manual (ODCM), are presented in the attached statistical tables in accordance with*Table 1 of Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear 0 0*Page 2 of 15 0 0 0 S 0 S 0 0 0 0 0 0 0 S S 0 0 0 0 0 0 0 0 0 0 0 0 0 Power Plants." Sample collection was conducted by plant chemistry/environmental staff. A contract vendor (Environmental Inc., Northbrook, Illinois) performed sample analyses, preparation of monthly reports and the statistical evaluation of sample results.All vendor analysis techniques met the sensitivity requirements as stated in the ODCM.Results for 2011 were within expected ranges and compared closely with historical results, with the following exceptions.

On March 11, 2011 an earthquake and subsequent tsunami damaged the Fukushima reactor complex in Japan. The subsequent release from the damaged facilities was detected at nuclear facilities worldwide.

Air particulate samples put in service on 16 March 2011 and collected on 23 March 2011 identified 1-131 in all locations including the control location.

The identification of 1-131 in all locations continued for another 2 weekly sample sets. Iodine continued to be identified in various REMP samplers until 4/20/2011.

The Missouri river experienced a protracted flooding event. Large snow melts and heavy early season Dakota rains filled the upstream reservoirs to capacity.

Dams released at records flows for several months submerging a large portion of the site.Some TLD locations and one groundwater well sampling location were either submerged, or made inaccessible due to swift currents.

The following is a review of specific sample results.1) Ambient Gamma Radiation Ambient gamma radiation is measured by thermoluminescent dosimeters (TLDs)provided by the vendor laboratory.

These dosimeters contain calcium sulfate phosphors and are processed quarterly.

Thirty-two new thermoluminescent dosimeters were added to the program during the fourth quarter of 2010.All sample results are within the range of historical data and displayed less than 20% difference when compared to historical averages.

Some locations displayed a low bias during the second and third quarter due to shielding from flood waters.Several TLD's could not be retrieved or were retrieved late due to floodwaters.

Those locations are listed in Table 3. No discrepancy between released effluents and resultant radiation dose measured was observed.

No changes in plant operation/procedures are required based upon observed impacts to the environment to date.10-Year Trend Comparison of TLD Locations Location Avg. Dose (mr/week).

2) Milk/Pasture Milk samples are collected every two weeks during the pasture season from the beginning of May through September, and monthly the rest of the calendar year.Indicator samples are collected from a herd of milk goats at a family farm located approximately

0.7 miles

from the plant in Sector K (South-Southwest).

The control samples are collected from a commercial dairy cow herd located approximately

9.9 miles

from the plant in Sector J (South). These locations are unchanged from last year.All milk sample results for Cesium-1 34, Cesium-1 37 and other gammas were at the LLD for both indicator and control locations.

One milk sample did identify I-131 at the control location.

This identification occurred during the Post Fukushima time frame (March 31). No plant-related effects were observed.3) Fish Fish are collected on an annual basis. Control samples are collected at a location approximately twenty miles upstream of the plant (river miles 665 -667).Indicator samples are collected in the immediate vicinity of the power plant (river miles 644 -646). Several. species of fish, important to commercial and recreational interest, representing all levels of the aquatic food chain are collected at both locations.

All sample results are within the range of historical data. Results from both control and indicator locations were less than LLD for all gamma emitters, indicating no plant-related effects.4) Food Crop Based on the results of the biennial Land Use Survey, the nearest high deposition pathway for food crops is the Alvin Pechnik Farm in Sector H Page 4 of 15 0 0 0 0 0 0 0 0 S 0 0 S 0 0 0 S 0 0 0 0 0 0 0 0 (0.94 miles, 1630). Accordingly, vegetable samples were collected at Alvin Pechnik Farm for the purposes of the 2011 REMP.Samples were comparable with historical results and within the range of results reported from the control location garden at Mohr Dairy.All results were at the LLD for all non-naturally occurring radionuclides.

No plant-related effects were observed.5) Sediment River sediment samples are collected twice a year at an upstream control location and a downstream indicator location.All results were at the LLD for all non-naturally occurring radionuclides.

No plant-related effects were observed.6) Air Monitoring Air sample results for 2011 were well within historical limits for all locations.

Additionally, all indicator locations showed results very similar to the control locations.

All sample results are within the range of historical data. All indicator locations displayed less than 7% difference when compared to historical average. All 2011 results when compared to historical averages are within the stated vendor error acceptance tolerance.

Results from both control and indicator locations were less than LLD for gamma emitters and iodine, except Post Fukushima results. Table C-1 1-131 Activity in Air Samples, documents the month long period when sample results were impacted.

Similar iodine detection levels were measured on both plant effluent stacks during the impacted period. Iodine released from plant effluents was compared with the last 2 years in which iodine release did occur. The 2011 total iodine effluent release was approximately 2-25% of the past station iodine release totals. Past higher effluent releases produced no identification of iodine in REMP sampling.

No discrepancy between released effluents and resultant radiation dose measured was observed.

No changes in plant operation/procedures are required based upon observed impacts to the environment to date.10-Year Trend Comparison of Air Sampling Locations Location Avg. Beta (pCi/m 3) 2011 Avg.

7) Surface Water Water samples are collected upstream of the plant (control location) as well as half-mile downstream and at a municipal water treatment plant on the north edge of Omaha.Results for Cs-1 34, Cs-1 37, and other gammas were all less than LLD. Tritium results were also less than LLD. No plant-related effects were detected.8) Ground Water Quarterly residential well water samples are collected at the following locations:

Station No. 15, Smith Farm, Station No. 20, Mohr Dairy, Station No. 33, Bansen Farm and Station No. 40, Herber Acreage. All sample results to date have been at the LLD except gross beta due to naturally occurring radionuclides.

Gross beta results have ranged from a low of 3.0 pCi/liter to a high of 56.4 pCi/liter, with an average gross beta for the year of 12.0 pCi/liter.

Strontium-90 analysis is being conducted on wells as part of the station's groundwater protection program. No plant-related effects were detected.Page 6 of 15 0 0 0 0 0 0 0 0 0 0 S S 0 0 0 0 0 S 0 0 0 0 0 0 0 0 Table 1.0 Sample Collection Program.Number of Number of Samples Collection Sample Collected Sample Class Frequency Locations This Period Background Radiation (TLDs) Quarterly 47 183 Air Particulates Weekly 6 311 Airborne Iodine Weekly 6 311 Milk Semimonthly 2 22 Surface Water Monthly 3 36 Ground Water Quarterly 4 15 Fish Annually 2 5 Sediment Semiannually 2 4 Food Crops Annually 3 6 TOTAL 893 Page 7 of 15 Table 2.0 Radiological Environmental Monitoring Program Summary Name of Facility Fort Calhoun Nuclear P Location of Facility Washington, Nebraska Reporting Period January-December, 2011 ower Station -Unit 1 Docket No. 50-295 0 0 0 0 0 0 0 0 S 0 0 0 (County, State )Indicator Location with Highest Control Number Sample Type and Locations Annual Mean Locations Non-Type Number of LLDb Mean (F)0 Mean (F)' Mean (F)0 Routine (Units) Analyses' Range' Locationd Range 0 Range' Results'Background Gamma 183 0.5 1.4 (179/179)

Environmental Inc. participates in interlaboratory comparison (cross-check) programs as part of its quality control*program.

These programs are operated by such agencies as the Department of*Energy, which supply blind-spike samples such as milk or water containing

concentrations of radionuclides unknown to the testing laboratory.

This type of program provides an independent check of the analytical laboratory's procedures and processes,*and provides indication of possible weaknesses.

In addition, Environmental Inc. has its*own in-house QA program of blind-spike and duplicate analyses.0 Vendor in-house spike sampling was performed without a failure and in-house blank analyses were performed within acceptable ranges.*One failure was observed from QA samples performed as part of the Environmental

Resource Associates Inter-laboratory Comparison Cross-check Program. Surface water sample STW-1257, experienced high results for a Cesium-134.

Cs-134 was*measured at 38.8 +/- 8 pCi/I with an acceptable band of 26.3-36.7 pCi/I. The sample*was re-performed and produced acceptable results. Water sample STW-1257 was a*gamma scan with five isotopes present. -Four were correctly processed.

Since no Cs-134 was identified in station REMP samples during the reporting period, the slight high bias had no impact. OPPD results were not negatively identified by this vendor*identified issue. Four DOE mixed analyte failures occurred during the calendar year.*STSO-1 251 failed low on Sr-90 and Tc-99, both passed on reanalysis.

STSO-1240*failed low on Ni-63. A math error on per cent recovery was discovered which after recalculation, produced acceptable results. None of these soil analyses are part of the* FCS REMP program. STAP-1241 failed high on Sr-90. The analysis was re-performed

successfully.

No reason for the failure was listed. Sr-90 is part of the FCS RETS*program, not the REMP, and is analyzed by a different vendor. STW- 1237 failed on for Am-241 at 0.35 pCi/I for a range of 0.37 to-0.69 pCi/I. The analysis was repeated and failed low again. Matrix spikes were prepared to verify the method, and both passed,*verifying the method. Am-241 has been added to the vendor's internal spike and blank*program for 2012 to further identify any potential issue. Am-241 is not part of the FCS*REMP program.*These results indicate the vendor's ability to self-identify and correct any deviations from*acceptable or expected results. The test results had no impact on Fort Calhoun samples and were documented as such by the vendor.0 S 0 S 0 0 0*Page 15 of 15 0 0 0 0 S 0 0 0 S 0 0 S phone (847) 564-0700.

Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported.

Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.January through December, 2011 A-1 0 0 S 0 S S 0 S 0 0 S S 0 0 0 S S 0 0 0 0 Appendix A Interlaboratory Comparison Program Results 0 0 Environmental, Inc, Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies Which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories.

The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control 0limits indicate a need to check the instruments or procedures used.Results in Table A-1 were obtained through participation in the environmental sample crosscheck program S administered by Environmental Resources Associates, serving as a replacement for studies conducted*previously by the U.S. EPA Environmental Monitoring Systems Laboratory, 'Las Vegas, Nevada.oTable A-2 lists results for thermoluminescent dosimeters (TLDs), via International 0Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples 0t are prepared using NIST traceable sources. Data for previous years available -upon request.0 Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for 0previous years available upon request.0* Table A-5 lists REMP specific.analytical results from the in-house "duplicate' program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors.*Complete analytical data for duplicate analyses is available upon request.The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation 0Program.0 Results in Table A-7 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted*previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).Attachment A lists the laboratory precision at the I sigma level for various analyses.

Single Measurements Each single measurement is reported as follows: x +/- s where: x = value of the measurement; 0s = 2s counting uncertainty (corresponding to the 95% confidence level).0*! In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.3.0.

4.0. Computation

of Averages and Standard Deviations

4.1 Averages

and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations.

The average x and standard deviation s of a set of n numbers xi, x 2 ... xn are defined as follows: Sx =n Ix s=n-*D 4.2 Values below the highest lower limit of detection are not included in the average.4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.0*1 4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.4.5 In rounding off, the following rules are followed:* 4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the*retained figures are kept unchanged.

As an example, 11.443 is rounded off to 11.44.4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45.4.6 Composite samples which overlap the next month or year are reported for the month or year in which most of the sample is collected.
