INTRODUCTION l

(}

V Radiolooical Environmental Monitorina Proaram-1994 The following represents the Fort Calhoun Station (FCS) Annual Radiological

, Environmental Operating Report-1994. Results of completed sample analyses as I

required by the Offsite Dose Calculation Manual (0DCM) are presented in the attached tables. Collection of environmental sample media was performed by the Utility (Omaha Public Power District) and sample analysis was performed by contract vendor (Teledyne Brown Engineering--Northbrook, Illinois). Data obtained in the 1994 Program in comparison were well within the predicted mean ranges as

> historically assessed in previous years' monitoring efforts. No station effect on j the environment was indicated. The following observations were documented:

1

1) Tritium was detected in one surface water fourth quarter composite sample collected 0.5 miles downstream of the Plant (858 pCi/L or 8.58E-07 Ci/ml).

Re-evaluation confirms this presence. The 40 CFR 141 and ODCM limit for Tritium in drinking water is 20,000 pCi/L. Plant staff reviewed effluent release data for this timeframe and found no abnormalities that would support this concentration.

2) Cesium-137 was detected in two bottom sediment samples 0.5 miles downstream ofthePlant(0.10610.038 pCi/g dry, 0.033 20.017 pCi/gdry). However, the i levels reported are consistent with normal environmental levels present and j can be attributed to fallout.

1

(] 3) Routinely, in order to satisfy the ODCM environmental specification for fish I ' sample analysis, several fish species of commercial and recreational value are analyzed. Fish are collected from a cross-section of the existing feeding classes in the Missouri River to effectively monitor in part, the ingestion pathway. However, one selected indicator species, the Gizzard Shad, could not be located in the target area during the monitoring effort due to low river levels and hot weather causing this species to migrate out of the monitoring radius into more preferred habitat. Therefore, it was necessary to deviate from the Program and collect additional numbers of another desired species in order to comply with the ODCM requirement for fish. As a result, it was necessary to composite some of the fish collected.

For the indicator location, the ODCM requires a total of 4 fish to be analyzed. Ultimately, thirteen fish were collected and analyzed. This ,

deviation is allowed by the appropriate procedure and does not result in a '

reduction of Program effectiveness. All results, both indicator and co.n trol I were <LLD.

l

4) Air sampling units operated with an improvement in total downtime again for i 1994, resulting in only two samples not analyzed. One occurrence was for l routine maintenance and the other was due to an open fuse in the unit. The overall effectiveness of the Program was not reduced as a result.

l APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS r,

NOTE: Teledyne Isotopes Midwest Laboratory participates in intercomparison studies administered by U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported in Appendix A. Also reported are results of InternationalIntercomparison and Teledyne testing of TLD's, as well as, in-house spikes, blanks and duplicates. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly

( progress reports only. Please refer to March, June, September and December progress reports for information.

O, January,1994 through December,1994

]

Aependix A I Interlaboratory Comparison Procram Results Teledyne's 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 know 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 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 program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

'Ihis program is conducted by the U.S. Environmental Protection Agency Intercompanson and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), since 1976 via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2. Also Teledyne testing results are listed.

Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months.

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. j l

Table A-5 list results of the in-house " duplicate" program for the past twelve months. Acceptance i is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.

Attachment A lists acceptance criteria for " spiked" samples. l l

It states, "The Radiation Quality Assurance Program has been experiencing problems with the Ruthenium-106 currently used in the Performance Evaluation (PE)

Studies and in the Standards Distribution Program. If these problems can be satisfactorily resolved, this analyte will once again be placed into this PE Study. If the problems cannot be resolved, the Ruthenium-106 will be replaced. Formal written notice will be given to all participants in the Gamma in Water PE Study before the Ruthenium-106 is reintroduced or replaced. At that time, new calibration standards will be available to all participants in the Gamma in Water PE Study." Teledyne will continue to monitor this situation, but at this time, plans to take no additional action.

b 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 Maacurements Each single measurement is reported as follows:

xts where x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level).

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

<L where L = the lower limit of detection based on 4.66o uncertainty for a background sample.

4.0. Comoutation 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 averagei and standard deviation (s) of a set of n numbers x1, x2. . . x n are defined as follows:

i=1Ex

,, [I(x - x,)2 1 n-1 4.2 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 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 f3 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 greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.446 is rounded off to 11.45.

4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, the figure five is dropped, and the last-place figure retained isincreased by one if it is an odd number or it is kept unchanged if an even number. As an example,11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.
