1.0 INTRODUCTION

The following constitutes the current Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at the Consumers Power Company, Palisades Nuclear Generating Plant.

Results of completed analyses are presented in the attached tables. Missing entries indicate analyses that are ~ot yet completed.

Data obtained in the program are well within the ranges previously encounted in the program and to be expected in the environmental media sampled.

For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 KeV. Speicifically included are Mn-54, Fe-59, Co-58, Ccr60, Zn-65, Zr-95, Nb-95, 1-131, Ba-La-140, Cs-134 and Cs-137.

Naturally-occuring gamma-errlitters, such as K-40 and Ra daughters, are frequently detected but not listed here. Data listed as"<" are at the 4.66 sigma level, others are 2 sigma.

All concentrations, except gross beta, are decay corrected the time of collection.

All samples were collected within the scheduled period Wlless noted otherwise in the Listing of Missed Samples .

INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE: Teledyne's Midwest Laboratory participates-in intercomparison studies ad.ministered by U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported in Appendix A; Also reported are results of International lntercomparison and Teledyne testing of TLD's, as well as, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program. Appendix A is updated four times a year; the complete Append.ix is included in March, June, September and December monthly progress reports only. Please refer to March, June, September and December progress reports for infonnatim.

January, 1996 through December, 1996

Appencij1 A lnterlaboratocy Comparison Program 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 instrwnents 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.

This program is conducted by the U.S. Enviror;unental Protection Agency lntercomparison and Calibration Section, Quality Ass\irance Branch, Environmental Monitoring and Support Laboratory, Las Veg8;9, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (Tl.Os), 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.

All samples are prepared using NIST tracable sources. Data for previous years available upon request.

Table A-4 lists results of the analyses on in-house "'blank~ samples for the pas't 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 .As.9essment Program.

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

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