INTRODUCTION Radiological Environmental Monitoring Progqram (REMP) - 2001 The Fort Calhoun Station (FCS), owned and operated by Omaha Public Power District, conducts a stringent environmental radiological monitoring program.
This program was initiated prior to plant operation in 1973 and continues to be performed as a requirement of the facility-operating license. Pre-operational and operational environmental monitoring data generated have been recorded and will be archived for the duration of the plant's existence. This submittal contains the results of the Radiological Environmental Monitoring Program (REMP) and the operatives required for the FCS Annual Radiological Environmental Operating Report for year 2001.
The primary function of the REMP is to ensure the overall safety of the general public by monitoring plant liquid and gaseous discharges to the environment. The data accumulated is utilized to assess the overall impact of plant operation on the environment and to determine whether adjustments to plant operations or the REMP are needed.
Program objectives are accomplished by monitoring the potential radiation exposure pathways to the public including adsorption, inhalation, ingestion, and direct exposure. Both grab samples and composite samples are collected and analyzed to represent these exposure pathways including air, water, milk, vegetation, fish, sediment, and food crops. Direct exposure is monitored by utilizing thermoluminescent dosimeters (TLDs) that are installed in the field at several locations, including air monitoring stations. Samples are collected at both control (background) and indicator locations, which are selected based on radiological, meteorological, and geographical factors that are obtained from the Annual Effluent Release Report and the Environmental Land Use Survey.
Most monitoring is conducted within a five-mile radius circle centered on plant containment. However, some samples, typically control samples, are collected outside of five miles. This circle is divided into sixteen equal sectors of 22.5 degrees each. Each sector is assigned an identification letter "A" through "R" (note: letters "I" and "0" are not used as they may be mistaken for the numbers one and zero). Sector "A" is centered on North or zero degrees. Sectors are also given directional labels such as west-southwest ("WSW"). Sample locations are assigned a station number and their distance and direction from plant containment are listed in the Offsite Dose Calculation Manual (ODCM). Sample locations are also marked on sector maps maintained by the Environmental Group.
In interpreting the data, results due to plant operation are distinguished from those due to other sources by comparing control sample results (upwind, upstream, or distant) to indicator sample results (downstream, downwind, or nearby) for each type of sample collected. The program uses analysis Page 2 of 11
techniques that are sufficiently sensitive to detect radiation levels far below those that are considered hazardous to humans. A station attributable effect could be indicated if the sample results at an indicator location are significantly larger than those at the control location. The difference would have to be greater than that which could be accounted for by typical fluctuations in radiation from other sources. In year 2001, the activity present in some of the routinely sampled media was determined to be from plant sources, although any plant affects on the environment were considered negligible.
Results of completed 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." The plant chemistry and environmental staff conducted the environmental sampling required by the REMP. A contract vendor (Environmental Inc., Northbrook, Illinois) performed sample analyses, preparation of monthly progress reports, and the statistical evaluation of sample analyses.
Results for this reporting period were generally within expected ranges and compared favorably to historical trends. The following observations were documented during the monitoring period:
- 1)
AMBIENT GAMMA RADIATION-TLD All environmental dosimeters were recovered and analyzed. A data comparison for years 2000 and 2001 indicated no overall increase in gamma radiation to the unrestricted area. The mean dose (mr/week) for all indicator locations for year 2001 was actually slightly lower than that for year 2000. Data was well within the expected range and no negative trend was identified. As a result, no observable environmental impact is indicated that would require changes or modifications to plant systems or operation.
- 2)
MILK I VEGETATION Milk samples were available within the five-mile monitoring area for most of the grazing season (May to October). However, during the first part of the grazing season milk was not available at the indicator location.
Therefore, vegetation (pasture grass) was collected in lieu of milk at both the indicator and the control locations until milk was available. Results for 1-131 and other gamma emitting isotopes were all <LLD for both milk and vegetation. No adverse environmental effects were observed. One duplicate pasture grass sample (May 17, 2001) was inadvertently combined with the original sample from the same location by the vendor and analyzed as a composite sample, however, the results were <LLD. A reanalysis could not be performed because the vendor had disposed of the sample. A condition report was initiated to acknowledge the occurrence. It was determined that because the results of the sample Page 3 of 11
analysis were <LLD, there was no adverse environmental affect observed.
No plant systems or operational modifications are required as a result of these findings.
- 3)
FISH Comparison of 2000 and 2001 analyses indicate no adverse trend. All indicator and control fish sample analyses were <LLD as expected.
During shipping to the vendor for analysis, one ice chest containing fish samples appeared to have been vandalized while enroute. However, the fish samples were ultimately recovered by the courier and delivered to the vendor intact for analysis. A condition report was initiated to acknowledge this occurrence. No plant systems or operational modifications are required as a result of these findings.
- 4)
FOOD CROPS Garden vegetable samples were collected at the offsite indicator location (resident receptor) determined to have the highest potential for exposure as a result of plant operation. Vegetables were also collected at a control location outside of the five-mile monitoring area. Analyses were all <LLD.
Year 2001 data compared favorably with year 2000 data, as expected. No negative trend was identified. Therefore, no plant system or operational modifications will be implemented as a result of these findings.
- 5)
SEDIMENT Bottom sediment sample analyses were all <LLD for both indicator and control locations for 2001. This compared favorably with results from 2000. No plant systems or operational modifications will be required.
- 6)
AIR MONITORING Comparison of 2000 and 2001 air monitoring data indicates that results are consistent with data from previous years. There were no incidents of downtime or missed samples during 2001. One monitor experienced a brief timer malfunction when the timer was found to be intermittently running slow. Actual time elapsed was used to calculate results for that sample. A condition report was initiated to document this occurrence. No modifications are required as a result of this occurrence.
- 7)
WATER Fourth quarter water results (tritium composite) were greater than analytical lower limit of detection (300 pCi/L). A condition report was initiated to acknowledge these results, which required plant staff to conduct a chemistry evaluation of effluent release data for the period in Page 4 of 11
which the activity was found. The following evaluation will look at plant effluents as a possible source and doses attributed to those positive samples versus theoretical dose calculated from chemistry software.
Downstream location OSW-B-I tritium was determined by the vendor (Environmental Inc.) to be 487 pCi/L for the fourth quarter. The vendor reanalyzed the sample, which confirmed original results. Additionally, each monthly composite sample for the fourth quarter was analyzed separately with the following results: October - 557 pCi/L, November 583 pCi/L, and December - 60 pCi/L. During the December sampling period (December 5-26, 2001) no monitor tanks were released.
Environmental samples were performed during monitor tank releases during October and November. A calculation of tritium concentration at site discharge during these monitor tank releases was performed. Using the low mixing value listed in the ODCM, the Missouri River was extremely low during the sampling period. The concentration at site discharge for Monitor Tank (MT) Release 2001156 was 1336 pCi/L and for MT 2001165 was 1127 pCi/L. Creating a composite for October and November using these calculated values and the sample volumes obtained from the environmental samples during periods of no release would result in composite values consistent with the Environmental Inc. findings. The average monitor tank tritium concentration for the quarter was 0.0969 ýtCi/ml. A dose calculation was performed using the quarterly discharged volume and this average tritium concentration using Genie software. The result was 4.9E-03 mrem. A dose estimate was also performed using the equations listed in the ODCM and the positive sample result. For the determination, an adult was assumed to drink water at 487 pCi/L for one quarter at the rate listed in Table 6. The dose from that calculation was 5.3E-03 mrem (487pCi/L
- 730L/yr *.25yr
- 5.99E-08 mrem/pCi).
In summation, no changes are required to the FCS effluent processes due to this positive environmental result. The dose attributed to the positive result is consistent with that estimated by LADTAP software. The level of this positive sample is well below the reporting level of 20,000 pCi/L. The dose estimated represents 0.16% of the annual limit of 3 mrem. A condition report was written. No plant system or operational modifications are required as a result of these findings.

Review of Environmental Inc., Quality Assurance Program Fort Calhoun Station contracts with Environmental Inc., Midwest Laboratory (vendor) to perform radioanalysis of environmental samples. Environmental Inc. participates in interlaboratory comparison (crosscheck) programs, as part of its quality control program.
These programs are operated by agencies such as the Department of Energy which supply blind-spike environmental type 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 testing 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.
The plant staff reviewed the vendor's Interlaboratory Comparison Program for 2001 and noted that a total of seven standards analyzed did not meet the required acceptance criteria specifications. As a result, a chemistry evaluation was conducted to determine if these inconsistencies affected REMP sample analyses. The findings of the evaluation indicated that the vendor's explanations and corrective actions were appropriate and that the standards not meeting acceptance criteria did not affect REMP sample analyses.
During the year 2001, Environmental Inc. reported the following discrepancies:
Samole Code/Tvre Date Comments STW-921/Water SPW-483/Water SPMI-1270/Milk SPMI-3233/Milk July, 2001 Jan. 2001 Mar. 2001 Apr. 2001 Lab results for Sr-89 were 19.8 +/- 1.5 pCi/L; Control limits: 22.5 - 39.9. Delay in processing may have contributed to deviation. Reanalysis results were within limits, 35.3 +/- 4.4 pCi/L.
Results for OPPD water samples for gamma isotopes <LLD for the year.
Lab results for Ra-228 were 10.55 +/- 2.02 pCi/L; Control limits: 13.6 - 25.26. Insufficient sample available to perform reanalysis.
Lab results for Cs-137 were 46.61 +/- 8.81 pCi/L; Control limits: 25.90 - 45.90. A new Cs-137 spike was prepared. Reference sample SPMI-3232, which was within limits. No OPPD milk samples were collected or analyzed during March.
Lab results for Sr-90 were 1.18 +/- 0.35 pCi/L; Control limits: <1.0. Low levels of Sr-90 are detected in the environment. These results are not unusual for milk. No OPPD milk samples were collected or analyzed during April.

Low levels of Sr-90 are detected in the environment. These results are not unusual for milk. OPPD milk sample results for July were <LLD for all gamma emitters except K-40, which is naturally occurring.
Lab results for Am-241 were <0.8 Bq/Kg; Control limits: 0.0 - 2.6. Results are considered a false positive as no activity was expected. OPPD does not at this time collect soil samples.
Lab results for Bi-212 were 53.20 +/- 3.1 Bg/Kg; Control limits (which are determined by the ratio of Reported Value/EML value) were 0.45 - 1.23.
Naturally occurring radium and thorium daughters are present in the shield background and a probable cause of the higher bias seen for bismuth. OPPD does not collect soil samples at this time.
Additional Notes:
Sample STW-921/Water was provided by Environmental Resources Associates for the Interlaboratory Comparison program. Samples SPW-483/Water, and SPMI-1270/Milk, were in-house "spike" samples. Samples SPMI-3233/Milk,and SPMI-6146/Milk were in house "blank" samples. Sample STSO-923/Soil, was part of the Department of Energy's Mixed Analyte Performance Evaluation Program. Sample STSO-904/Soil was provided by the Environmental Laboratory Quality Assessment Program (EML).

Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services 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 (e.g., milk or water) 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.
The results ir-Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.
This program was conducted by the U.S. Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.
The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.
Results of crosscheck testing with Teledyne Brown Engineering are also listed.
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 list results of 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. Data for previous years available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

APPENDIX B DATA REPORTING CONVENTIONS B-1
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; x, +/- s, and x2 +/- S2 Reported result:
x +/- s; where x = (1/2) (xi + x2) and s = (1/2) st +s2 3.2.
Individual results:
<LI, <L2 Reported result: <L, where L = lower of L, 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 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,, x2... xn are defined as follows:
S-1X 2
n n-i 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.
