1.0 INTRODUCTION

l Byron Station, a two unit PWR plant, is located about two miles east of the Rock River and approximately three miles southwest of Byron in Ogle County, north central Illinois.

Each reactor will have a capacity of 1120 MW Net.

The plant is currently under construction and the purpose of the present environmental radiological monitoring program is to establish background, or baseline values with which to compare levels of radioactivity in the environment when the station is in operation.

The Environmental Radiological Monitoring Program at Byron commenced in July 1981.

This fourth report represents the data acquired during the period from January through December 1984.

Monitoring is conducted by sagling a variety of environmental media f rom stations chosen to be representative of locations where any releases from the plant, when it is operational, will likely to be observed.

Analyses followed standard procedures and are described in Section 2.10.

The Byron program is sumarized in Tables 1.0-1 through 1.0-3 and the description of the samling locations are shown in Figures 1.0-1 through 1.0-3..

Data listings are found in the tables of Appendix 1.

The Interlaboratory Comparison Program Results are listed in Appendix Ill.

SUMMARY

Radioactivity in all samples, as_ expected from samples collected in the area, was within-the range of values for these media.

Specific findings for various' i

environmental media are discussed on the following pages..

l 2.1 Background Radiation 4

~

radiation dose rates were measured using lithium fluoride 8ackground i

thermoluminescent dosimeters (TLDs).

Each badge consisted of five LiF i

chips sealed in plastic envelopes having a density of about 15 mg/cm2, Badges are located at each of-the air sampling locations.

Additional TLDs, a total of 64, were installed on September 28, 1981, such that each sector was covered at both five miles and the site bound-ary. Data obtained were within' the ranges to be expected in the area.

2.2 Airborne Particulates and Iodine-131 Air particulate filters and charcoal cartridges were exchanged at twelve sampling locations.

Four of the locations were added to the program in April of 1984.

The filters were exchanged weekly; charcoal cartridges 4

were exchanged bi-monthly until the end of October of 1984 and weekly afterwards.

Gross beta concentration in air particulate samples ranged from less than 0.004 to 0.060 pCi/m3 with an average of 0.027 pCi/m,

3

_Results of gamma isotopic analyses of quarterly composites of-air partic--

ate filters from each sampling lccation indicated ~ the absence of any _

gomma emitters which were above the detection limit of the program of 0.01 pCi/m3 Iodine-131 concentration ~ was below the LLD level of 0.10-pCi/m3 in all samples.

i 14

2.3 Surface Water Surf ace water samples were collected weekly f rom five locations and analyzed for gross beta content. Weekly samples from the intake and discharge pipes were composited monthly and analyzed for gamma emitters, tritium, and Sr-89 and Sr-90.

Samples from other loca-tions were composited monthly for gamma isotopic analysis and quarterly for tritium, Sr-89 and Sr-90.

None of the composite samples indicated the presence of other than naturally-occurring gama emitters at a sensitivity of 10 pCi/1 and 2 pCi/1, respec-tively.

Tritium concentrations were below the LLD level of 200 pCi/l in all samples but two.

The detected concentrations were 230 and 200.pCi/1.

Since counting uncertainty is of the order of 100 pCi/1, the detected concentration levels' are not statistically significant.

2.4 Milk Milk samples f rom f our nearby f arms were collected monthly, with the.

exception for the month of October 1984, when samples were collected twice.

Beginning in October 1984, sampling frequency for milk was changed to semimonthly during' the pasture season (May through October) and to monthly during the rest of the year.

Samples were analyzed for I-131 (with' exceptions for the months of January through' April) for Sr-89, Sr-90, and gamma-emitters.

Levels of I-131 were below the detection. limit of the program for all samples collected during the sampling period.

Sr-90 concentrations were variable within the usual range for milk, and.Sr-89 and gamma-emitters were below the limits of detection.

2.5 Grass And Cattlefeed Grass and cattlefeed samples are collected from the same farms as the milk samples on a quarterly basis and analyzed for gross beta, Sr-89, Sr-90, and gamma emitters.

Sr-89 and Sr-90 concen-trations were below the LLD of 1 pCi/g wet weight in all samples.

Gross beta concentrations were variable-within the usual range for grass and cattlefeed.

Gamma isotopic analyses indicated the presence of naturally occur ring-gamma emitters and were below the detection limit. of the program of 0.2 pCi/g wet -weight for all samples collected.

I 2.6 Samples From The Aquatic Environment Fish, sediments, and aquatic plants were collected three times per year and analyzed for gross beta concentrations, gamma emitters, and Sr-89 and Sr-90.

Gross beta concentrations were typical for each of the sampled media during the period, and no gamma emitters, other than those which occur naturally were detected in samples collected.

Values for Sr-89 and Sr-90 in fish were below 0.1 pCi/g wet weight for the period.

2.7 Well Water Well water was collected from one on-site well on a monthly basis, and from one off-site well on a quarterly basis.

Gross beta analysis was performed on all samples, and gamma isotopic, radiostrontium, and tritium analyses on the quarterly samples from the off-site well and on a quar-terly composites of monthly samples from the on-site well.

No unusual results have been observed in analyses performed during the period; however, the on-site well' had gross beta concentrations slightly higher than near-by surface water, indicating.the presence of slightly elevated concentrations of naturally occuring radionuclides.

2.8 Precipitation Samples. of precipitation were collected from four f arms on a. monthly basis.

All samples were analyzed for gross beta activity, and quarterly composites of monthly samples were analyzed for gamma emitters, radio-strontium, and tritium.

No unusual findings were made.

'2.9 Vegetables Samples of vegetables were collected at harvest time at f arms in the area. No unusual findings were made.

2.10 Analytical Procedures A description of the procedures used for analyzing radioactivity in environmental samples.is given in Appendix IV of the report for the period January - December 1983.

Procedures used during the period covered by this report remained essentially unchanged.

'r Appendix III Interlaboratory Comparison Program Results l

Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its 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 concentrations 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 environ-mental sample crosscheck program for milk and water samples during the period 1980 through 1984.

This program has been conducted by the U. S. Environmental Protection Agency Intercomparison 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 (TLD's) during the period 1976, 1977, 1979, 1980, and 1981 through parti-cipation in the Second, Third, Fourth, and Fif th International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.
