INTRODUCTION Radiolo-gical Environmental Monitorinq Program (REMP) - 2014 This report gives the results of the Radiological Environmental Monitoring Program (REMP) for the year 2014.
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.
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 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 2014 were within expected ranges and compared closely with historical results. The result details and exceptions are listed in the following sections.

: 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.
One incident was documented in the Corrective Action Program in 2014 related to thermoluminescent dosimeters (TLDs). The TLD OTD-H-(I) was damaged in the hail storm that occurred on June 3, 2014.
The testing vendor was notified of the damage and the TLD was sent to the vendor to be analyzed. The returned results were evaluated for their validity. The results appeared to be consistent with the results from previous quarters and to nearby TLDs, so the results were deemed to be valid and the damaged TLD was not included as a missed/lost sample.
All sample results are within the range of historical data and displayed less than 20% difference when compared to historical averages. All results were less than 3 sigma standard deviations from historical means. 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.

: 2) Milk/Pasture Milk samples or pasture grasses, if milk is temporarily unavailable, 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 3.4 miles from the plant in Sector J (South). The control samples are collected from a commercial dairy cow herd located approximately 9.9 miles from the plant in Sector J (South). This indicator station was added in March of 2013, the control location is unchanged from last year. No indicator milk sample was available in December due to the does drying up before birthing; pasture grass in lieu of milk was collected at the indicator location.
All sample results for Cesium-1 34, Cesium-1 37 and other gammas were at the LLD for both indicator and control locations. 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 (0.94 miles, 1630). Accordingly, vegetable samples were collected at Alvin Pechnik Farm for the purposes of the 2014 REMP.
Samples were comparable with historical results and within the range of results reported from the control location garden at Mohr Dairy. Additional special interest samples were obtained from on-site farm fields per plant Technical Specifications.
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 2014 were well within historical limits for all locations. Additionally, all indicator locations showed results very similar to the control locations.
Seven incidents were documented in the Corrective Action Program in 2014 related to air sampling.
Each is discussed below.

The package of environmental samples for air monitoring dated 03/05/2014 was damaged in transit.
Subsequently, the air particulate and iodine cartridge filters for OAP-l-(l) and OAP-K-(I) were lost. The transport vendor was contacted to report the damage and to try to recover the missing samples. The damage was reported, but the attempt to recover the samples was unsuccessful. The samples were considered lost and are addressed in accordance with section 5.1.1 .A-7 of the Offsite Dose Calculation Manual.
During sample collection on 04/16/2014, for location OAP-I-(I), the sampler noticed that the particulate filter was missing. The sampler examined the area around the sample station, but did not recover the missing particulate filter. The iodine charcoal cartridge was sent to the vendor for radioactive iodine analysis. The iodine results on the iodine charcoal cartridge were at the LLD. The particulate filter sample was considered lost and is addressed in accordance with section 5.1 .1 .A-7 of the Offsite Dose Calculation Manual.
On 04/23/2014, the environmental air sampler as found flow value in the field at location OAP-D-(l) was found to be high and out of tolerance. The flow, as found in the field by the sampler, was 2.6 SCFM; the acceptance range is 1.8-2.2 SCFM. The unit was replaced and a bench test was performed to verify the as found flow. The bench flow rate was found to be 2.3 SCFM. The bench test confirmed that the flow was high out of the tolerance. The bench test flow rate was used to calculate the volume through the sampler because it was the conservative approach. The returned analytical results were reviewed for consistencies in gross beta and to verify the LLD 1-131. The results were within the normal statistical limits and the LLD's were per the Offsite Dose Calculation Manual, so the sample was deemed to be acceptable.
There were four incidents of power failures at air sampling locations during 2014. The power outages occurred, at OAP-D-(I) for 4.90 hours on 11/19/2014, at OAP-K-(I) for 3 hours during the time frame of 9/24/2014 to 10/1/2014, at OAP-K-(I) for 30 hours during the time frame of 7/2/2014 to 7/9/2014, and at OAP-B-(l) and OAP-J-(I) for 4 hours during the time frame of 8/27/2014 to 9/3/2014. The returned analytical results were reviewed for consistencies in gross beta and to verify the LLD 1-131. The results were within the normal statistical limits and the LLD's were per the Offsite Dose Calculation Manual, so the sample was deemed to be acceptable.
All sample results are within the range of historical data. All indicator locations displayed less than 19%
difference when compared to historical average. All 2014 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.
No changes in plant operation/procedures are required based upon observed impacts to the environment to date.

: 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 four locations: Station No. 15:
Smith Farm, Station No. 20: Mohr Dairy, Station No. 74: D. Miller Farm and Station No. 75: Lomp 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 2.0 pCi/liter to a high of 6.8 pCi/liter, with an average gross beta for the year of 4.0 pCi/liter for indicator locations. Strontium-90 analysis is being conducted on wells as part of the station's groundwater protection program. No plant-related effects were detected.

LLD = nominal lower limit of detection based on a 95% confidence level.
Mean and range are based on detectable measurements only (i.e., >LLD) Fraction of detectable measurements at specified locations is indicated in parentheses (F).
Locations are specified: (1) by code, (2) by name, and (3) by distance and direction relative to the Reactor Containment Building.
Non-routine results are those which exceed ten times the control station value. If no control station value is available, the result is considered non-routine if it exceeds the typical pre-operational value for the medium or location.

Review of Environmental Inc., Quality Assurance Program Fort Calhoun Station contracts with Environmental Inc., Midwest Laboratory (vendor lab) to perform radioanalysis of environmental samples. 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.
Vendor in-house spike sampling was performed without a failure and in-house blank analyses were performed within acceptable ranges.
ERA soil sample ERSO-1 050 and DOE soil sample MASO-1 146 failed testing for plutonium isotopes during first quarter testing. These four failures (high bias) were traced back to a cross contaminated source set.
MAAP-1 151 air filter failed its PU-238 testing because of this faulty standard set. The results of re-analysis with a replacement tracer purchased from NIST produced satisfactory results. MASO-1 146 also failed (low) for uranium isotopes. This issue is under current investigation. Since over 80% of the testing labs had unacceptable results, it appears that the DOE sample may be suspect. The FCS REMP program does not perform transuranic analyses of soil or air filters.
MASO-1146 also failed for Cs-134 in the gamma scan. The testing listed Cs-134 as present, when the sample had none. The sample was recounted, and two gamma spectral lines for Cs-134 were present. Six other gamma nuclides were identified correctly on each count. No further explanation was provided for the failures.
FCS REMP program does perform gamma scans of soil/river sediment; no Cs-1 34 was detected in station samples tested.
MAAP-1 151 air particulate filter, failed a gamma scan for Co-57. This was caused by EU-1 52 library issue.
Re-analysis with the interfering line addressed produced acceptable result. No plant related nuclides were detected in FCS REMP gamma scans.
ERW- 055 failed low on Fe-55 testing. An efficiency calculation error was discovered. After recalculation the sample passed. A new test was reordered and performed with satisfactory results. The DOE water sample, MAW-4431, failed high.
The DOE sample in question was reanalyzed and produced satisfactory results. Both the DOE and ERA water sample failed initial testing. Since FCS Fe-55 is performed within the RETS program, the environmental vendor does not receive a Fe-55 analytics cross check. The RETS/Rad waste vendor did pass its testing, and no Fe-55 was identified in station effluent reporting.
No test results failed both the ERA and DOE methodologies for a given sample type. Reanalysis produced acceptable results. The ordering of additional tests and successful testing after corrections were applied, visibly demonstrates the vendor's commitment to reporting and resolving deficiencies.
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.

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.

Appendix A Interlaboratory Comparison Program Results 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 limits 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 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.
Table A-2 lists results for thermoluminescent dosimeters (TLDs), via International Intercomparison 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 are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.
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 Program.
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 1 sigma level for various analyses. The acceptance criteria in Table A-3 is set at +/- 2 sigma.
Out-of-limit results are explained directly below the result.

b Laboratory codes as follows: ERW (water), ERAP (air filter), ERSO (soil), ERVE (vegetation). Results are reported in units of pCi/L, except for air filters (pCi/Filter), vegetation and soil (pCi/kg).
Unless otherwise indicated, the laboratory result Is given as the mean +/-t standard deviation for three determinations.
d Results are presented as the known values, expected laboratory precision (1 sigma, 1 determination) and control limits as provided by ERA. A known value of "zero" indicates an analysis was included in the testing series as a "false positive". Control limits are not provided.
The high bias on the plutonium crosscheck samples was traced to contamination from a newly purchased standard.

APPENDIX B DATA REPORTING CONVENTIONS

Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.
2.0. Single Measurements Each single measurement is reported as follows:                 x+/-s where:           x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).
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. Duplicate analyses 3.1    Individual results:  For two analysis results; xi +/- Sl and x2 +/- s2 Reported result:     x +/- s; where    x = (1/2) (xi + x2) and s =           2s2 + 2 3.2. Individual results:      <Li , <L2          Reported result: <L, where L = lower of Li and L2 3.3. Individual results:        x+s, <L            Reported result:      x +/- s       if   x > L; <L otherwise.
4.0. Computation of Averaqes and Standard Deviations B-2

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 x 1 , x2 ... xn are defined as follows:
                             - 1 yx                 s        y( n-)  2 x=~
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.
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.

A. Location is either not in use or currently discontinued and is documented in the table for reference only.
B. If milk samples are temporarily not available at a sampling site due to mitigating circumstances, then vegetation (broadleaf, pasture grass, etc.) shall be collected as an alternate sample at the site. If there are no milk producers within the entire 5-mile radius of the plant, then vegetation shall be collected monthly, when available, at two offsite locations having the highest calculated annual average ground level D/Q and a background locale. (Reference Off-Site Dose Calculation Manual, Part II, Table 4 "Highest Potential Exposure Pathways for Estimating Dose")
C. Locations represent highest potential exposure pathways as determined by the biennial Land Use Survey D. Background location (control). All other locations are indicators.
E. Location for monitoring Sector K High Exposure Pathway Resident Receptor for inhalation.
F. When broad leaf (pasture grasses) are being collected in lieu of milk, background broad leaf samples will be collected at a background locale.
