I e 5.9.4.b Radioloaical Environmental Operatina Reoert Summary

1. Table 1 describes for each sample class, the collection frequency, number of sample locations and the number of samples collected during this period.

2. A statistical evaluation of the program findings is presented in Table 2. For each sample type and analysis this table considers all indicator locations, all control locations, and the location with the highest annual mean result. Table 2 contains the following information:

A. The total number of analyses.

B. The fraction of these analyses yielding detect ole results (i.e., results above the highest lower limit of dete: tion (LLD) for the period).

C. The average, lowest and highest results.

The distance and direction relative to the reactor containment building are specified for the location with the highest annual mean.

No Station effect on the environment was indicated.

3. All analyses of gamma isotopes for fish were below the analysis detection level except for one buffalo and gizzard shad composite sample which indicated 0.057 pCi/gm. No plant attributable effect is indicated, as supported by the lower than LLD results for all the other fish and surface water analyses.

4. Table 3 is a listing of missed samples.

5. Appendix A contairs a description of the Interlaboratory Comparison Program Results.

6. The land use survey is conducted biennially. The last survey was completed in 1990; the next survey will be performed during 1992.

7. The limits of Technical Specification 2.1.3 were not exceeded by the primary coolant during the reporting period.

Appendix 3 Engt-taboratory Comparison Program Results 1

) Tcledyne isotopes Midwest laboratory (formerly Hazleton Environmental Sciences) has participated in 1 j interlaboratory comparison (crosscheck) pmgrams since the tormulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g.,

milk or water) coritairiing; concentrations of radionuclides known to the issuing agency but not te ,

partiupant hboratories. The purpcse of such a program is to provide an independent check on the l '

laboratory's analytical procedures and to alert it to any posible problems.

1 Participant laboratories measure the concentration of specified radionuclides and report them to th(

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.

i

'fhe results in Table A 1 were obtained H. rough participation in the environmental sample crosscheci program for milk, water, air filters, and food samples dudng the period January 1988 through November 1991. This program has been conducted by the U.S. Environmental Protection Agency intercomparisor 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) during the period 1976 l 1977,1979,1980,1984, and 1985-86 through participation in the Second, Third, Fourth, Fifth, Seventh, and '

Eighth International Intercomparison of Environmental Dostraters under the sponsorships listed ir

EPA TIML Centrol Result Limit 12b Code Analysis (pCl/L)a (pCi/L)a Explanation STM-570 Sr-89 26.0110.0 30.3-47.7 The cause of low results was falsely high Sr 90 45.714.2 49.8-60.2 recovery due to suspected incomplce calcium removal. Since EPA sample was used up, internal spike was prepared and analyzed. The results were within control limits (See table A-3, sample QC-MI-24).

No further action is planned.
