0 0 INTRODUCTION

• Radiological Environmental Monitoring Program (REMP)- 2013 0

This report gives the results of the Radiological Environmental Monitoring Program (REMP) for the year 2013. 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 while 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 I* containment, in the Offsite Dose Calculation Manual (ODCM).

When assessing sample results, data from indicator locations most likely to be effected by plant operations are compared to control locations 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 0 (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 0 stated in the ODCM.

0 Results for 2013 were within expected ranges and compared closely with historical results, with the following exceptions.

0 1) Ambient Gamma Radiation 0 Ambient gamma radiation is measured by thermoluminescent dosimeters (TLDs) provided by 0 the vendor laboratory. These dosimeters contain calcium sulfate phosphors and are 0 processed quarterly. Thirty-two new thermoluminescent dosimeters were added to the 0 program during the fourth quarter of 2010.

0 All sample results are within the range of historical data and displayed less than 16%

difference when compared to historical averages. All results were less than 3 sigma standard 0 deviations from historical means. No discrepancy between released effluents and resultant 0 radiation dose measured was observed. No changes in plant operation/procedures are 0 required based upon observed impacts to the environment to date.

0 0 2) Milk/Pasture 0 Milk samples or pasture grasses, if milk is temporarily unavailable, are collected every two 0 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 0 the plant in Sector J (South). This indicator station was added in March of this year, the control location is unchanged from last year. No indicator sample of vegetation was available 0 in February due to freezing conditions and no milk locations being present within 5 miles.

0 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 0

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 2013 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.

0

5) Sediment

• River sediment samples are collected twice a year at an upstream control location (0.09 miles,

• 40 N) and a downstream indicator location (0.45 miles, 1080 ESE).

0 All results were at the LLD for all non-naturally occurring radionuclides. No plant-related effects were observed.

0

6) Air Monitoring Air sample results for 2013 were well within historical limits for all locations. Additionally, all 0*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 8% difference when compared to historical average. All 2013 results when compared to historical averages are within the stated vendor error acceptance tolerance.

S

• 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.

0 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.

0

• Vendor in-house spike sampling was performed without a failure and in-house blank analyses were performed within acceptable ranges.

0

• Water sample ERW-1257 was performed in 2012 to determine isotopes of radium.

Determinations for Ra-226 and Ra-228 displayed a high bias. Reanalysis of both samples produced acceptable results. No reason was given for the failures. A new

• test was ordered from ERA to be performed in the first quarter of 2013. That test,

• ERW-6022, failed in February of 2013 again with a high bias. The test was again re-

• performed, and like last year, produced acceptable results. It was determined that interference from short lived radon daughters Pb-214 and Bi-214 was producing the high bias. Allowing decay time removes the bias. Radium analysis is not part of the

• FCS REMP program. OPPD results were not negatively impacted by this vendor

• identified and corrected issue.

DOE MAPEP air particulate sample MAAP-738 failed low at 0.14 pCi/filter with an

• acceptable range of 0.36-2.04. The sample was re-analyzed and no alpha activity

• was detected. The sample was counted per enclosed instructions; however the filter

• appears to have been loaded on the wrong side. When the sample was flipped over, gross alpha was determined to be 0.61 pCi/filter in the acceptable range.

• Gross alpha air particulate analysis is not part of the FCS REMP program. Air

• particulate gross beta, which would not be impacted by the misloaded sample, and

• is part of the FCS REMP program was performed on the same sample successfully.

OPPD results were not negatively impacted by this vendor identified and corrected issue. DOE air particulate sample MAAP-5046 was performed in the 3rd qtr. Gross

• alpha & gross beta were once again performed satisfactory. Additional gamma scan

• and transuranic analyses were performed. One of the four transuranic tests, for U-

• 233/234, had a high bias. The sample was reanalyzed, with acceptable results.

Uranium analysis is not part of the FCS REMP program. OPPD results were not

• negatively impacted by these vendor identified issues. Gamma counts from control

• or indicator spectrums had plant related nuclides present. A sample geometry

• adjustment was made and the sample recounted. The re-performed analysis was within acceptable limits (6.74).

0 Two failures occurred on analysis of MAPEP soil samples. MASO-744 failed low on Sr-90 (408.4bq/kq) for a range of 440-816 bq/kg. The sample was reanalyzed using 0 additional fuming nitric separations and produced acceptable results. Another soil 0 sample MASO-5043 was performed in the 3 rd quarter and had acceptable Sr-90 results. This soil sample however failed a gamma scan for Co-57(high), it was 0 determined to be an interference from Eu-1 52 being present in the sample. When the scan was corrected for this energy line interference, that 0 result fell within the 0 acceptance band of 0-5. Sr-90 analysis in soil is not part of the FCS REMP S program. OPPD gamma scan results on soil were not negatively impacted by this vendor identified issue.

0 No test results failed both the ERA and DOE methodologies for a given sample type.

0 Reanalysis produced acceptable results. Ordering of additional tests, and successfully testing after fixes were applied, visibly demonstrates the vendor's commitment to reporting and resolving deficiencies.

0 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 0 Calhoun samples and were documented as such by the vendor.

• Appendix A 1 Interlaboratory Comparison Proqram Results S

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 0known 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.

0Participant 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.

S Table A-2 lists results for thermoluminescent dosimeters (TLDs), via International 0Intercomparison 0 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 0 are prepared using NIST traceable sources. Data for previous years available upon request.

5Table 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.

5Results 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).

0t 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.

• Data Reportinq Conventions 01.0. 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; 0s = 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.

S 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 = (1/2)"s2 + s2 1

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 Averages and Standard Deviations S

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 5be the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x1 , x2 ... xn are defined as follows:

Sx = n s =

n

• • 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 5 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 Swhich most of the sample is collected.
