INTRODUCTION Radiological Environmental Monitorinq Program (REMP) - 2003 This report gives the results of the Radiological Environmental Monitoring Program (REMP) for the year 2003. 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, 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 "O" 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 2003 were within expected ranges and compared closely with historical results. 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 TLDs contain calcium sulfate phosphors, and are processed quarterly. Three indicator locations were added in 2003: OTD-P (Location No. 29) was added in Sector J in March as a result of most recent Land Use Survey results; OTD-Q and OTD-R were added in June to be co-located with possible new air sample locations. (NRC Branch Technical Position requires TLDs to be co-located with air samplers.) Locations Q and R ultimately were not needed for air sampling purposes and the TLDs have been discontinued at the end of first quarter 2004. The highest TLD results for the year were from the fourth quarter at OTD-Q (3.5 mRem per week) and OTD-R (3.7 mRem per week). Although these results are higher than normal, third quarter 2003 results and first quarter 2004 results are within normal ranges. Also, emergency plan TLDs and site TLDs maintained by the Dosimetry Group show no unusual fourth quarter results. This will be documented in a Condition Report. All other TLD results were within historical ranges. No plant-attributable results were seen, therefore, no changes are required in plant systems or operation.

2)

MilkNegetation Milk samples are required to be collected every two weeks, from May through September. The indicator samples are collected from a herd of goats located approximately 0.7 miles from the plant in Sector K (SSW),

Location No. 33. The control location for milk samples is a commercial dairy herd located approximately 9.9 miles from the plant in Sector J, Location No. 20 (S). These locations are unchanged from the previous year. The milk sample which would have been collected at the indicator location on May 1st was unavailable due to a fire which destroyed the barn on the property where the milk sample was stored in a refrigerator.

Pasture grass was collected instead. All results specifically for lodine-131, Cesium, and other gammas were <LLD for both indicator and control locations, as well as the substituted pasture sample. No plant-attributable results were seen. No changes to plant operations are required.

3)

Fish Several fish species, representing the aquatic food chain are collected at a downstream indicator location (River Mile 644-646) and an upstream control location (River Mile 665-667). Results from both locations were

<LLD for all gamma analysis, therefore, no plant-related effects are indicated and no changes to plant operation are required.

Page 3 of 15

4)

Food Crops Vegetable gardens were sampled at two locations. The indicator location is the same as that used for milk samples and is 0.7 miles from the plant in Sector K (SSW). The control location is the same as the milk control location, 9.9 miles from the plant in Sector J (S). All results were within historical ranges and <LLD for all gamma isotopes. Therefore, there were no plant-related effects and no changes to plant operations are required.

5)

Sediment River sediment samples are collected twice a year at an upstream control location and a downstream indicator location. All results were <LLD and no plant-related effects were observed and no changes to plant operations are required.

6)

Air Monitoring Three locations were discontinued and one added in March 2003. Those discontinued were: OAP-A (Sector P), OAP-C (Sector G) and OAP-H (Sector L); added was OAP-J (Sector J). These changes were made as a result of the previous Land Use Survey and LADTAP calculations.

All results for 2003 were within historical ranges, however, several Condition Reports (CRs) were written to document out-of-normal conditions:

a.

During the week of January 2-8, the air pump at location OAP-C shut down for approximately six hours. Instrument electricians suggested it may have been due to thermal overload as the pumps tend to run hot. Elapsed time from pump timer was used to calculate total flow, thus making dose results conservative.

b.

On February 22, a natural gas generator was installed at the Blair OPPD office (location OAP-D) requiring the power to be shut off to the yard where the air sampler is located. The time shown on the pump elapsed timer was verified to be correct for the length of the outage.

c.

In April, instrument electricians notified environmental that two air sample pumps showed problems when returned to the shop for routine maintenance. The pump from OAP-A was reading slightly high at 2.23 SCFM when the flow rate was checked (upper calibration limit is 2.2 SCFM). The pump was running within limits when started at the beginning of the week's sample period. To drift slightly high by 0.03 SCFM by the end of the week is not considered to have adversely affected sample results, which were within normal ranges and compared closely with air results from the control Page 4 of 15

location. The second pump, from location OAP-C, pegged high when checked in the shop. A screw was found to be missing from the intake manifold. The screw apparently fell out during transport to the shop, as it was operating normally in the field.

d.

Instrument electricians notified environmental that the air pump at location OAP-F was out-of-tolerance slightly high when brought to the shop. Flow rate was measured at 2.27 SCFM; upper limit is 2.2 SCFM. Results at-this location for the period this pump was in service, are well within historical ranges. The flow rate indicator on the pump itself, though not as accurate as shop measurements, did not show any abnormal performance while the pump was in the field.

Calculated results are conservative.

e.

A power outage of approximately 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> occurred at the Blair OPPD office (location OAP-D) during the first week in December.

The elapsed time from the pump timer was used to calculate total air volume. Sample results met required LLD.

f.

For the week of December 10-17, 2003, the timer on the air pump showed fewer hours than the back up timer. The back up timer showed 164 hours0.0019 days <br />0.0456 hours <br />2.71164e-4 weeks <br />6.2402e-5 months <br />, 49 minutes which agreed with the On/Off times recorded by the technician in the field on December 10 at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br /> and December 17 at 0850 hours0.00984 days <br />0.236 hours <br />0.00141 weeks <br />3.23425e-4 months <br />. The back up timer was used to calculate total volume.

No plant-related effects were observed in air sample results, therefore, no changes to plant operations are required.

7)

Water Samples Detectable tritium results were seen in the first and second quarter of 2003 at the downstream river sample location. Tritium is analyzed on a quarterly frequency. First quarter results were 1876 + 144 pCiIL, and for the second quarter 1048 +/- 122 pCi/L. Both of these quarterly results were well below the reporting level of 20,000 pCi/L for drinking water.

Individual month results for the first quarter were as follows:

January 46 pCi/L February 3014 pCi/L March 2167 pCi/L River water samples were collected during monitor tank releases each month. Tritium concentration calculations at the discharge point were calculated using the mixing value listed in the Off-Site Dose Calculation Manual (ODCM). The calculated concentration at discharge for monitor tank release number 2003013 was 2070 pCi/L and for release Page 5 of 15

number 2003012, 2144 pCifL. Creating a composite for the quarter using these calculated values and the standard environmental sample volumes during periods of no releases would result in composite values consistent with Environmental Inc. results. The average monitor tank tritium concentration for the quarter was 0.111 pCi/mL. A dose calculation using Genie software, quarterly discharge volume, and the above average, yielded a calculated dose of 5.9E-03 mRem. A dose estimate was also performed using the equation listed in the ODCM, the quarterly sample result of 1876 pCiIL, and the adult consumption rate listed in Table 6.

That calculation resulted in a dose estimate of 2.05E-02 mRem. The estimated dose represents 0.68% of the annual limit of 3 mRem.

Monthly tritium results for the second quarter were as follows:

April 3019 pCi/L May 108 pCi/L June 103 pCVL Downstream river water samples were collected during monitor tank releases in April. Using the mixing ratio in the ODCM, tritium concentration at the discharge was calculated to be 4015 pCi/L for release number 2003029. Creating a composite for the quarter using these calculated values and the standard environmental sample volume during periods of no release would result in composite values consistent with Environmental Inc. results. The average monitor tank tritium concentration for the second quarterwas 0.164 pCi/mL. A dose calculation using this concentration, the quarterly discharge volume and Genie software, yielded a calculated dose of 7.73E-03 mRem. Dose estimates were also calculated using the equations listed in the ODCM and the sample results from Environmental Inc. For this calculation, an adult was assumed to drink water at 1048 pCi/L for one quarter at the rate listed in Table 6. This resulted in a calculated dose of 1.15E-02 mRem.

This calculated dose represents 0.38 percent of the annual limit of 3 mRem.

In summation, no changes are needed to the FCS effluent process due to these positive results. 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 for drinking water. There was no change in the level or volume of release, but there had been changes in how releases were conducted. FCS had recently changed to 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> shifts. Monitor tanks were sampled on one shift and released on another. The present shift schedule will have every tank sampled on nights being released during the day. This increases the likelihood that a monitor tank release will occur during the time an environmental sample is being collected. The tritium levels or volume of tank releases have not changed.

Location is either not In use or currently discontinued and Is documented in the table for reference only.

When a milk sample is not available at a location, a broad leaf (pasture grass) vegetation sample will be collected at that location as a substitute.

Locations represent highest potential exposure pathways as determined by the biennial Land Use Survey, performed In accordance with Part 1, Section 6.3.2, and are monitored as such.

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 lype 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 vendor's 2003 QA results were all performed satisfactorily. There were no outstanding items.

Appendix A Interlaboratorv 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 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.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via Intemational Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. Results of internal laboratory testing is 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. 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.

Attachment A lists acceptance criteria for 'spiked' samples.

Out-of-limit results are explained directly below the result.

0 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 1 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 analvses

3.1 Individualresults

Fortwoanalysisresults;xl --s and x2 - S2 Reported result:

x +/- s; where x = (1/2) (xi + x2) and s = (1/2) 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 h 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 xl, x2... xn are defined as follows:

x 2 x s=I 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 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.
