2) The sample class, sample collection frequency, number of sample locations, and the number of samples collected this reporting period for each class is delineated in Table 1.0.

3) A statistical evaluation of REMP findings is summarized in Table 2.0, in accordance with Regulatory Guide 4.8, Table 1. For each type of sample medium and analysis, Table 2.0 exhibits separately all indicator locations, all control (background) locations, and the I locatP n having the highest annual mean result. For each of these classes, Table 2.0 specifies the following:

a. The total number of analyses.

b. The fraction of analys:s yielding detectable results (i.e., results above the highest Lower Limit of Detection (LLD) for this period).

l l c. The maximum, minimum, and average results.

d. The coordinates in distance in miles and the direction relative to the FCS Reactor i Containment Building (radial degrees) are specified for the location with the highest )

annual mean.

l INTRODUCTION Radiological Environmental Monitoring Program (REMP) - 1998 The enclosed submittal is the Fort Calhoun Station (FCS) Annual Radiological Environmental Operating Report - 1998, documenting the results of the Radiological Environmental Monitoring Program (REMP). Results of completed analyses as required by the FCS Offsite Dose Calculation Manual (ODCM) are presented in the attached tables. The collection of environmental sample media

l was performed entirely by plant staff and sample analysis / progress report preparation was provided by contract vendor (Teledyne Brown Engineering-Northbrook, Illinois). Data obtained for the REMP this reporting period were well within expected ranges and compared favorably to historical trends. None of the media sampled contained radioactivity attributable to the operation of the Fort Calhoun Station. The following observations and anomalies were documented during the

monitoring period:

1) Water - Tritium was detected in the first and fourth quarter composite samples collected 0.5 miles downstream of the Plant at an analytical LLD of 300 pCi/L (499

98 pCi/L, and 411 I 96 pCi/L, respectively). The 40 CFR 141 limit for tritium in drinking water is 20,000 pCi/L. Plant staff reviewed effluent release data for this period and found no abnormalities. Evaluation of tritium analyses data from the nearest downstream municipal drinking water intake (Metropolitan Utilities District-Omaha, Nebraska) indicated no detectable levels in surface (raw) water or drinking water.

2) Milk - Samples could not be collected at the indicator location for milk (Seltz Farm, 1 2.7 miles /168 radial degrees) after July 2,1998, due to illness in the family. The Land Use Survey revealed no other milk producers in the 5-mile interest area. As a result, broadleaf/ pasture grass samples were collected as a milk substitute for the remainder of the year.

l 3) Sediment - Cesium-137 was detected in one bottom sediment sample at the control location (upstream ofplant). Analysis results were 0.045 0.020 pCi/g dry at an LLD of 0.027 pCi/g ,

dry. Results reponed are consistent with normal environmental levels present and can be l attributed to fallout.

! Appendix A. Also muyvid are results of International Intercomparison and Teledyne testing of l TLD's, as well as, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results. 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 Teledyne Brown Engineering Environmental Services Midwest Laboratory (formerly Hazleton Environmental Sciences) 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 the laboratory's analytical procedures and to alert it to 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 l

control limits indicate a need to check the instruments or procedures used.

The results in Table A-1 were obtained through participation in the environmental sample crosscheck I program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

This program is conducted by the U.S. Environmental Protection Agency Office of Research and Developement National Exposure Research Laboratory Characterization Research Division-Las Vegas, I Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various I International Intercomparisons of Envirorunental Dosimeters under the sponsorships listed in Table A-2.

Also Teledyne testing results are listed.

I 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 I on the difference of the results being less than the sum of the errors. Data for previous years available UPonrequest The results in Table 4-6 were obtained through participation in the mixed analyte performance ovaluation 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.

' The Environmental Measurements Laboratory provides the following nuclear species : Air Filters, Soil, Tissue, Vegetation and Water. Teledyne does not participate in the Tissue program.

Results ara reported in Bq/L with the following exceptions: Air Filter results are reported in Bq/Filtef', Soil results are reported in Bq/Kg, Vegetation results are reported in Bq/Kg The results of elemental Uranium are reported in ug/filtei', g, or ml.

Teledyne results are reported as the mean of three determmationsistandard deviation.

d The EML result listed is the mean of replicate determinations for each nuclideithe standard error of the mean.

The control limits are reported by EML and are established from percentiles of historic data distributions (1982-1992). The evaluation of this historic data and the development of the controllimits is presented in DOE report EML-564.

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. Singla Me==urements Each single measurement is reported as follows:

xiS I

5 where x = value of the measurement; s = 20 counting uncertainty (corresponding to the 95% confidence level).

In cases where the activityis found to be below the lower limit of detection L it is reported as

<L where L = the lower lim.t of detection based on 4.660 uncertainty for a background sample.

3.0. Duplicate analyses

{

3.1 Individual results: x1 is1 x2 i s2 Reported result- xis where x = (1/2) (x1 + x2) s = (1/2) k 2s ,,j 3.2. Individual results: .L<i

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 x3, x2. . . xn are defined as follows:

i= Ix s= I (x- x)2 n-1 42 Values below the highest lower limit of detection are not included in the average.

4.3 If all of the 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 erroris 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.
