1. 0 INTRODUCTION ','

9 Braidwood Station, a two unit PWR plant, is located in Will County, Illinois, [ ' . .'

fif teen (15) miles south-southwest of Joliet, Illinois, Each reactor will - ' '

have a capacity of 1120 MW Net. The plant is currently under construction and 1 . ,

the purpose of the present environmental radiological monitoring program is to -

establish background, or baseline values with which to compare levels of . y. . . -

radioactivity in the environment when the station is in operation. +

The Environmental Radiological Monitoring Program at Braidwood commenced in - a..

July 1983. This fourth report represents the data acquired during the period '.- /'

from January through December 1985.  ;

Monitoring is conducted by sampling a variety of environmental media from stations chosen to be representative of locations where any releases f rom "

the plant, when it is operational, will likely to be observed. Analyses '1 .

followed standard procedures and are described in Section 2.10 The Braidwood program is summarized in Tables 1.0-1 through 1.0-3 and the description of the ,

sampling 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. There was slight effect on radioactivity levels in air particulate, air iodine, and in milk due to the fallout from the accident at Chernobyl Nuclear Reactor No. 4 (USSR) on April 26, 1986.

2.1 Background Radiation Background radiation dose rates were measured using lithium fluoride thermoluminescent dosimeters (TLDs). Each badge consisted of five LiF -

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 58, were installed on March 30, 1984, 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.

l 2.2 Airborne I-131 and Particulate Analysis for I-131 began on May 9,1986 at locations 80-1,2,3,4,5, and

6. On August 8,1986, four additional air sampling locations were added to the program and analyses for I-131 and gross beta began on August 17, 1986. Airborne I-131 remaine:1 below the LLD of 0.07 pC1/m3 throughout the year except in samples collected on May 16, May 23, and May 30, 1986. Samples collected on these da ranging from <0.07 to 0.76 pCi/m3, averaging ys had various concentration 0.28 pCi/m3 The of I-131, presence of I-131 in the air in May,1986 is attributable to the f allout from the accident at Chernobyl Nuclear Reactor No. 4 (USSR) on April 26, 1986.

Exceot for the period from May 16, 1986 to June 7, 1986, gross beta concentrations ranged from 0.010 to 0.069 pCi/m3, and averaged 0.034 pCi/m3 During the period from May 16, 1986 to June 7 1986, gross beta concentrations ranged from 0.069 % 0.281 pCi/m3,and averaged 0.133 pCi/m3 Elevated levels of grou beta during this period is attributable to the f allout from the nucle v reactor accident at Chernobyl.

Gamma isotopic analyses of the second quarter composites showed the presence of three isotopes: Ru-103, Cs-134, and Cs-137, averaging 0.010, 0.011, and 0.014 pCi/m3 respectively. These isotopes were below their respective LLD levels in the first, third, and fourth quarter composites.

All other gamma-emitting isotopes and Sr-89 and -90 activities were below their respective LLD levels.

2.3 Precipitation Samples of precipitat'9n 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 ganah emitters, radio-strontium, and tritium. No unusual findings were made.

l: 2.4 Milk Milk . samples were collected monthly from November through April and- 3 weekly'from May through October at four locations and analyzed for iodine-131 and oama-emitting isotopes. Monthly and monthly composite -

' samples were analyzed for Sr-89 and Sr-90. Sr-90. concentrations' were

' variable within the-usual range for milk and'Sr-89 was-below the-limit'of detection. 1 I-131 remained below the detection limit of 1.0 pCi/l except in samples-collected from May 9,1986 to July 3,1986.

Sixteen (16); milk samples collected during this period had various levels of I-131 ranging from 1.0 to 82.2 pCi/1 and averaging' 22.7 pC1/1.

Cs-134 was detected in three (3) samples and averaged 8.1 pCi/1 (range:

6.5 - 9.0 pCi/1). Cs-137 was detected in twenty-two (22) samples collected between May 23, 1986 and October 25, 1986 and averaged 9.8 pCi/1 ranging from 5.6 to 17.2 pCi/1.

Elevated levels of I-131, Cs-134, and Cs-137 during the . indicated collec-tion periods is attributable to the f allout from the Chenobyl nuclear reactor accident. There was no indication of the effect on the environ-ment due to station operation.

2.5 Surface Water Surf ace . water samples were collected weekly from four locations and analyzed for gross beta content.- Gross beta concentrations were at the level expected in. surface water samples, except in samples collected during the third quarter at location BD-7, Kankakee River Upstream.

While average gross beta concentrations during the second and fourth quarters was 3.6 pCi/1, the average gross beta conenetration during the third quarter was 18.8 pCi/1.

2.6 Well Water Well water - was collected from one off-site well on a qu5 ly basis.

Gross beta, gamma isotopic, radiostrontium, and tritium analyses were performed on all samples. Sr-89, Sr-90, tritium and gansna emitters were below the detection limit. Gross beta activity was within the expected level.

2.7 Vegetables Samples of vegetables we e collected at harvest time at f arms in the area and analzyed for gross beta, strontium-89 and -90, and gamma-emitting isotopes. Samples of leafy vegetables (cabbage) were also analyzed for I-131. No unusual findings were made.

BRAIDWOOD 2.8 Grass and Cattlefeed Grass and cattle feed samples were collected from the same farms as the milk samples on a querterly basis and analyzed for gross beta, Sr-89, Sr-90, and gamma emitters. Sr-89 and Sr-90 concentrations were below the LLD of 1 pCi/g wet weight in all samples. Gross beta concen-trations were variable within the usual range for grass and cattlefeed.

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

2.9 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 gama emitters, other than those which occur naturally, were detected in fish and aquatic vegetation.

Low levels of Cs-137 were detected in bottom sediments. Values for Sr-89 and Sr-90 in fish were below 0.1 pCi/g wet weight for the period.

2.10 An:lytical Procedures A summary of the procedures used for analyzing radioactivity in environ-mental samples is given in Appendix IV of the report for the period January-December 1985. Procedures used during the period covered by this report remained essentially unchanged.

2.11 Milch Animal and Nearest Residence Census See Appendix II.

2.12 Program Modifications Following program modifications were made in 1986:

a. Analysis for airborne I-131 began on May 9.

b. Three additional air sampling locations (B0-19, 80-20, and BD-21) were added to the program. The operation began on August 8 and the analysis for I-131 and gross beta began on l

August 17.

c. Two additional precipitation sampling locations (80-17, Trotter's Farm, and 80-18, Biros Farm) were added on April 1.

d. Three additional TLD locations (80-19, 80-20, and BD-21) were added at the beginning of the fourth quarter.

e. Two additional milk sampling locations (80-17, Trotter's Farm, and 80-18, Biros Farm) were added on April 11.

I Interlaboratory Comparison Program Results 1

Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences)

'has participated in interlaboratory comparison (crosscheck) programs since the .j formulation of its quality control program in December 1971. These programs j 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 througn participation in the environ-mental sample crosscheck program for milk, water, air filters, and food samples during the period May 1984 through November 1986. This program has been conducted by the U. S. Environmental Protection Agency Intercomparison and l

Calibration Section, Quality Assurance Branch, Environmental Monitoring and i

Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) during the period 1976,1977,1979,1980,1984, and 1985-1986 through participation in the Second, Third, Fourth, Fif th, Seventh, and Eighth International Intercomparison of Environmental Dosimeters under the sponsor-ships listed in Table A-2.

Table A-3 lists results of the analyses on in-house spiked samples.

Table A-4 lists results of the analyses on in-house " blank" samples.
