?

2. l' GEOGRAPHY AND DEMOGRAPHY-2.1.1 . Site Location and Description 2.1.1.1 Specification of Location The Braidwood Nuclear Generating Station - Units 1 and 2 (Braidwood Station) is located in Reed Township of Will County northeastern Illinois approximately 50 miles southwest of Chicago and 20 miles south-southwest of Joliet. It is adjacent at its northwest corner to the village of Godley and its western and southern borders lie adjacent to the Grundy and Kankakee County boundary-lines, respec-tively. Tha site is in an area of flat agricultural farmland that has-been scarred from coal strip mining, and the site itself .is located principally on terrain that has been strip mined.

At its closest approach, the Kankakee River is approximately 3 miles east of the northeastern site boundary; this point is approx-imately 12 miles upstream of the headwaters of the Illinois River at the confluence of the Kankakee and Des Plaines Rivers. The Braidwood Station is located approximately 8 miles southwest of the 7s)

(_ Joliet Arsenal.

Figure 2.1-1 shows the location of the site within the State of Illinois, and Figure 2.1-2 outlines the site with respect to the Kankakee River and the county boundaries. The following coordi-nates of the center of containments are given in both latitude and longitude and Universal Transverse Mercator (UTM) Coordinates.

Latitude and longitude are given to the nearest second and UTM Coordinates are given to the nearest 100 meters.

Nuclear Unit Latitude and Longitude UTM Coordinates 1 880 13' 42" W x 410 14' 38" N 4,565,3'00 N 397,000 E 2 880 13' 42" W x 410 14' 36" N 4,565,200 N 397,000 E 2.1.1.2 Site Area The roughly rectangular site occupies approximately 4454 acres of $

which 2537 acres comprise the cooling pond. The pond has an eleva-tion of 595 feet above mean sea level (MSL) when filled to capac-ity. The plant property lines and the site boundary lines are the same. 1 The site boundary and the general outline of the pond are sho.n in Figure 2.1-3. As noted in this figure, the nuclear generating Os.

2.1-1

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 fccilities are located at the northwest corner of the site. Figure 2.1-4 shows the location and orientation of the principal plant structures. The makeup and blowdown lines are buried in the ground within a transmission line corridor and have their respective 1

source and terminus at the Kankakee River as shown in Figure 2.1-2.

The plant exclusion area, located within the site boundary, is illustrated in Figure 2.1-5. The minimum exclusion boundary dis-tance from the gaseous release point is 1625 feet.

There are no industrial, commercial, institutional, recreational, or residential structures on the site. Illinois State Routes 53 and 129 are adjacent to the northwest boundary of the site. The Illinois Central Gulf Railroad (previously the Gulf Mobile & Ohio Railroad) runs parallel between State Routes 53 and 129 and pro-vides spur track access from the site area to the main line. In-terstate 55 is less than 2 miles west-northwest of the site and State Route 113 is approximately 2 miles north of the site. Figure 2.1-6 illustrates these transportation routes. The Kankakee River is approximately 3 miles east of the northeastern site boundary.

2.1.1.3 Boundaries for Establishing Effluent Release Limits It is required by Title 10 of the Code of Federal Regulations Sec-tion 20.106 (10 CFR 20.106) that "a licensee shall not possess, lll use, or transfer licensed material so as to release to an unrc-stricted area radioactive material in concentrations which exceed the limits specified in Appendix 'B', Table II of this part . . .

"; it is further required by 10 CFR 50.34a that "in the case of an application filed on or after January 2, 1971, the application shall also identify the design objectives, and the means to be employed, for keeping levels of radioactive material in ef fluents to unrestricted areas as low as practicable."

The restricted area boundary, the boundary that separates the re-stricted area from the unrestricted by 10 CFR 20.106, is specified to be the plant property line for the Braidwood Station. Expected concentrations of radionuclides in effluents are shown in Sections 3.5 and 5.2 to be in compliance with 10 CFR 20.106 criteria.

Figure 2.1-3 illustrates the restricteo area boundary and Figure 2.1-2 shows the boundary with respect to the Kankakee River.

The distances from the release point of gaseous effluents (tne vent stack) to the restricted area boundary for each of the 16 direc-tional segments are given in Table 2.1-1. The site boundary clos-est to the release point of gaseous effluents is in the northwest-crn direction at a distance of 1625 feet.

FEBRUARY 1983 Liquid-effluents are discharged into the cooling pond blowdown line, which. subsequently discharges into the Kankakee River. Radi-onuclides in liquid effluents, therefore, enter the unrestricted area at that point.

The restricted area boundary is posted conspicuously with " Private Property No Trespassing" signs. 'In addition, administrative procedures include periodic patrolling.to control access to the area.

2.1.2 Population Distribution 2.1.2.1 Population within 10 Miles In order to assess the population distribution within a 10-mile radius of the Braidwood Station, a detailed analysis was per-formed. For this purpose, the region surrounding the station was divided into sixteen 22.50 azimuthal sectors centered on the centerline of the reactors with outer radial increments of 1, 2, 3, 4, 5, and 10 miles. The geographical locations of these sectors are identified in Figure 2.1-7. The 1970 and 1980 population den- 1 sities within these radial-azimuthal sectors were obtained by per-forming a house count from general highway maps for Will, Grundy, and Kankakee Counties based on 1968, 1969 and 1980 local census

() data. The population-center data were updated to the reported 1980 1 U.S. Bu; eau of Census values. All permanent residences were House counts were converted to population by assuming 3.4 counted.

persons per household based on 1970 U.S. Bureau of-Census data for Will County. Comparable values for Grundy and Kankakee Counties were 3.17 and 3.15, respectively.

The results of this analysis, as presented in Table 2.1-2, show that the 1980 population out to 10 miles was 28,548 corresponding i to an average population density in this area of 91 persons per square mile. The maximum population densities in the near vicinity of the plant occur in the northern sectors, which encompass the cities of Braidwood and Wilmington and the village of Coal City.

I The population data were projected over the expected 40-year oper-ating life of the plant by census decade using the modified ratio method. The basic formula used for the population projection by county was:

Pt = Po (1 + r)T Where: Pt = population in year t; Po = population in base year; r = average annual rate of population change; and T = number of years between the base year and the year

() of the projection (year t).

2.1-3

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 Based on previous census history (1940-1970), the rural population within 10 miles of the Braidwood Station has tended to remain con-stant in all the allinois counties of interest except Will and Grundy. Thus, except for these two counties, population growth was assumed to take place only near present urban centers (those loca-tions with a population greater than 2500).

The county population for the 1970 base year was subdivided into rural and urban components by township. The projected population increase in a county was distributed among townships at a level proportional to the magnitude of urban population in each township for the base year 1970. Rural townships were held constant at the 1970 census level.

Census data of Will and Grundy counties for the previous decade -

indicate that the population growth rate in rural areas is very similar to the rate characterizing urban areas. Thus, township populations in these two counties were assumed to increase at the same rate as the county population.

The rate of population growth in a particular county during the last decade (1960-1970) was used to obtain the county's annual rate of change, which is utilizec for the period up to and including 1990. On the assumption that the increase in population within this region over the period from 1970 to 1990 will be sufficiently large to divert migration from the greater Chicago area to other regions of northern Illinois, the annual population rate of change for all counties within the 10-mile radius after 1990 was tken to be the projected rate for the State of Illinois (about 1% per yeer) for that perod based on U.S. Census projection data. Onsite resi-dences were not included in the projected data. The projected population for the proposed Finger Lakes Estates mobile home park is included in the north-northeast sector in the 3-to 4-mile seg-ment. This projection was obtained by multiplying the proposed 800 units (U.S. Department of Housing and Urban Development 1977) by 2.3, the average number of persons living in owner-occupied mobile homes in Illinois according to the 1970 Census of Housing (Bureau of the Census 1972).

The results of this analysis of projected population distribut?qn are shown in Table 2.1-2 for the expected 40-year operating 11,; of the plant by census decade. From these projections, it is seen that the population within 10 miles of the site is expected to grow from 22,116 in 1970 to 47,577 in 2020, corresponding to an average population density of 151 persons per squate mile.

The projected national age distribution for the year 2000 (midpoint of station operating life) is 17.5% in the O to 11 age group, 11.1%

in the 12 to 18 age group, and 71.4% in the 19 and over age group 2.1-4

FEBRUARY 1983 (Bureau of the Census 1975). These percentages cor:espong to a projected 2000 population of 6,937 persons in the U to 11 age group, 4,400 persons in the 12 to 18 age group, and 28,303 persons in the 19.and over age group within 10 miles of the site. _The U.S.

projected age distribution was used because the area within a 10-mile radius of the site (Will, Kankakee, and Grundy Counties) did not show a significant difference from the 1970 U.S. Census age distribution (Bureau of the Census 1971).

When applying the significance test described in Appendix 0 of Regulatory Guide 4.2, Will County did vary more than 10% from the 1970 U.S. Census age distribution in one of the three age groups (14.7% in the 0-11 age group). However, Grundy and Kankakee Coun-ties did not significantly differ from the U.S. distribution. The average age distribution for the three counties did not vary more than 10% from the 1970 U.S. Census age distributio.n. Thus, it is assumtd that the area within a 10-mile radius of the site will have a projected age distribution similar to the U.S. projected age distribution.

Figure 2.1-8 locates cities and villages within 10 miles of the site and provides their 1980 populations. Only Braidwood, Coal City and Wilmington can be classified as urban centers (population

\;^

, greater than 2500) within 10 miles of the site. The village of Godley with a 1980 population of 373 is located approximately 0.5 1 mile southwest and west-southwest of the reactor. The city of Braidwood with a 1980 populaton of 3429 is located approximately 1.5 miles north and north-northeast of the station.

2.1.2.2 Population between 10 and 50 Miles The 1970 and 1980 population distribution and the estimated pro- 3 jected population distributions through 2020 at 10-year intervals for the area between 10 and 50 miles are summarized in Table 2.1-3. The geographical locations of the population sectors are found in Figure 2.1-9. The total population within 50 miles was 4,472,612 in 1980 with an average population density of 570 persons 1 per square mile. By 2020, the population is projected to grow to 7,559,624, which yialds a population density of 963 persons per -

square mile.

The most heavily populated sectors within 50 miles of the station lie in the north-northeast and northeast directions. The 1980 populations in those directions are 1,14 2,815 and 2,145,518, res-pectively. the high populations in these sectors is primarily due i to the inclusion of the City of Joliet (1980 population 77,956) and a portion of Chicago (1980 population 3,005,072). Also included in this area are some suburbs of Chicago.

l Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 To obtain the population figuies by sector, the U.S. Bureau of Census data for 1980 were used according to township, and the pop- i ulatin density within a township was assumed constant. Thus, the estimated fractional area of a township within a sector was useo to estimate the fraction of the township's population in that sector.;

all fractional townships within a sector were summed to give the population within that sector.

Population projections were ,jenerally made according to the same techniques used for the O- to 10-mile region, including the sectors within Indiana which have exhibited the same growth patterns as Illinois. The exceptions to this basic population projection model as used for the 10- to 50-mile region are:

a. Newton County, Indiana, whose entirely rural population was assumed to remain constant with time, in accord with census patterns that reveal that no significant increase in rural populations can be anticipated;

b. Chicago, in Cook County, Illinois, whose population has actu-ally experienced a decrease in the last decade and was assumed to remain constant at the 1970 census level; and

c. DuPage County, Illinois, whose townships containing small and Ih

~

continually declining rural populations were assumed to ex-hibit population growth at the same rate as the county.

The projected national age distribution for the year 2000 (midpoint of station operating life) is 17.5% in the O to 11 age group, 11.1%

in the 12 to 18 age group, and 71.4% in the 19 and over age group (Bureau of the Census 1975). These percentages correspond to a projected 2000 population of 1,093,384 perions in the O to 11 age group, 693,518 persons in the 12 to 18 age group, and 4,461,008 persons in the 19 and over age group within 50 miles of the site.

The U.S. projected age distribution was used because the area within a 50-mile radius of the station did not vary significantly from the 1970 U.S. Census age distribution described in Appendix 0 of Regulatory Guide 4.2 to the 50-mile area, six of the 18 counties within 50 miles dif fered more than 10% from the 1970 U.S. Census age distribution. However, the other 12 counties did not signifi-cantly differ from the U.S. distribution. Since the average age distributions for the 18 counties did not vary more than 10% from the 1970 census age distribution, it can be assumed that the area within a 50-mile radius of the site will have a projected age dis-tribution similar to the U.S. projected age distribution.

The nearest population center is Joliet, located approximately 20 miles north-northeast of the site. According to the 1970 popula-tion census, Joliet had a population of 80,378, and in 1980, $ q 2.1-6 L-

_ ,_ Braidwood ER-OLS AMENDMENT 1

~( ) FEBRUARY 1983 77,956, a dectuase of 3.1% during the last decade. Its expected 1 population is 150,389 by 2000, and 181,970 by 2020. The city o f Kankakee, located approximately 20 miles eastsoutheast of the site, had a 1970 population of 30,944, and in 1980, 30,141, and has an expected population of 44,800 oy 2000, and 55,000 by 2020. Table .1 2.1-4 lists the - 25 population ~ centers within 50 miles of the site and Figure 2.1-10 locates them. Most of these centers are located near the greater Chicago metropolitan area, 40 to 50 miles north-east of the site.

Table 2.1-5 lists the distance and approximate direction from the site of all urban centers (those locations with a- population greater than 2500) within a 30-mile radius of the site and gives their 1980 populations. It should be noted that there are only 22 such urban centers and that only two of these, Joliet and Kankakee, $

are population centers.

2.1.2.3. Transient Population The transient population within 10 miles of the site is composed of visitors to recreational facilities, students enrolled at and teaching staff employed by schools, and employees at industrial establishments.

As shown in Table 2.1-6, the state parks and conservation areas within a 10-mile radius of the site include the Des Plaines Conser-vation Area approximately 8 miles north of the site, the Goose Lake Prairie State Park approximately 9 miles north-northwest of the site, the Kankakee River State Park approximately 9 miles east of the site, and the Illinois and Michigan Canal State Trail (Channahon Park Access) approximately 10 miles north of the site.

In 1976, these four parks had a combined annual attendence of 1,699,722 persons (Illinois Department of Conservation 1976). The estimated peak daily attendances for these areas are respectively 1000, 462, 33,000, and 1000 visitors.

The Des Plaines camping, Conservation picnicking, Area consists fishing, boating, of 4253(Illinois and hunting acres and offers Department of Conservation 1976). The Goose Lake Prairie State Park consists of 2357 acres of which approximately 1513 acres are dedicated as an Illinois Nature Preserve. The park offers picnick-ing, hiking, and year-round nature study programs (Illinois Depart-

, ment of Conservation 1974). The Kankakee River State Park consist s of 2968 acres extending along the Kankakee River and offers camp ing, picnicking, fishing, boating, hiking, horse trails, hunting, and a summer nature study program (Illinois Department of Conserva-tion 1974). The Illinois and Michigan Canal State Trail is cur-rently being developed for hiking, bicycling, and canoeing. The O

Braidwood ER-OLS AMENOMENT 1 FEBRUARY 1983 llf portion of the trail near the Channahon access is now completed and offers camping, canoeing, bicycling, and hiking (Illinois Depart-r:nt of Conservation 1975).

In addition to these state recreational facilities, there are snveral privately owned recreation areas within 10 miles of the Braidwood Station. Table 2.1-6 lists these recreation areas along cith their location, their total membership, and their estimated p$ak daily attendance. These clubs and parks provide a variety of recreational activities and attract people from outside the 10-mile radius.

The estimated peak daily attendance figures in Table 2.1-6 indicate that on a short-term basis, the population within 10 miles of the station could increase by 51,437 persons due to both state and private facilities. Should all these visitors be from outside the 10-mile radius, the total population within the 10-mile area would increase by 233%.

As listed in Table 2.1-7, there are 10 industries within 10 miles of the station. Approximately 860 persons are employed at these industries. Even if all these people come from outside the 10-mile 1 area, which is highly unlikely, the total population of this area would only increase during working hours by about 3%.

lll As shown in Table 2.1-8, the total of 16 schoolr within 10 miles of' the site had a total 1981-1982 enre11 ment of 5625 students and a 1 staff of 332 teachers. The great majority of students attending these schools reside within a 10-mile radius of the station.

The 1970 and projected pooulation distributions within the 10-mile radius are given in Table 2.1-9. This table includes the residen-tial population and the peak daily transient population resulting j from recreational activities within the 10-mile area.

2.1.3 Uses of Adjacent Lands and Waters 2.1.3.1 Land Use 2.1.3.1.1 Land Use within 5 Miles The area within a 5-mile radius of the station includes land in Will, Kankakee, and Grundy Counties. This area as well as the remainder of Will, Kankakee, and Grundy Counties is predominantly agricultural. According to the 1974 farm statistics in Table 2.1-10, 64.8%, 89.7%, and 82.9% of the total land acreage in Will, '

Kankakee, and Grundy Counties, respectively, is farmland. The percentage of the total county land under cultivation is: Will County--55.1%, Kankakee County--79.3% and Grundy County--71.1%.

' Braidwood ER-OLS AMENDMENT 1 i FEBRUARY 1983 j jg I The major crops grown in the thice counties are corn and soybeans.

Hay, oats, and wheat are also grown in the area. Table 2.1-11 gives the 1974 and 1975 acreage, yield, production, and dollar value of these crops for the three counties and the State of Illinois. In general, Grundy and Kankakee counties were more pro-ductive in 1975 than the state average, with the exception of corn yield in Kankakee County, which was slightly less than the state average. In 1975 Will County was less productive than the state average, with the exception of wheat yield, which was slightly higher than the state average. In general, the number of acres +

devoted to corn and soybeans in the three counties decreased be-tween 1974 and 1975 while the number of acres devoted to wheat, oats, and hay increased.

Corn and soybeans are the major crops grown within a 5-mile radius of the site. A " pick your own" christmas tree, blueberry, and strawberry farm is located approximately 3.5 miles southeast of the station.

This mid-stream 1 Population estimates based on the total number of fish captured

Although the total number of fish marked and recaptured using this technique does not necessarily have to be large (Ricker 1958) , the obvious lack of sufficient numbers of marked and recaptured fish made the

j Age, growth, food habits, parasites, and condition factors of

rock bass, longear sunfish, smallmouth bass, largemouth bass, and

white crappie from the Kankakee River and Horse Creek were

! studied in 1974. The growth rates of these fish varied from f air i to good when compared with those of other fish populations

! described in literature. Also, except in the case of white l crappie, they had relatively higher condition factors (see Table i

2. 2-4 9) . Annual increments in length varied from year to year.

i

Select fish species of the Kankakee River and Horse Creek f ed on j a wide assortment of aquatic invertebrates and, in several cases, j on ninnows and other fish (see Figures 2.2-24 through 2.2-27) .

() Aquatic invertebrates were available in the study area throughout

the study period. Some invertebrate species were fed upon

selectively. In several cases, the changing feeding habits of j fish with the season was largely attributed to the seasonal j fluctuation of the benthic community.

i Fish collected from the Kankakee River and Horse Creek were i subject to parasitic infections. The degree of infection varied j among species. Parasitic ef fects were not severe, as indicated j by the growth patterns and condition f actors (see Table 2.2-50) .

4 In several cases fish were shown to host more than one species of l parasite at one time. The parasitic organisms encountered in the

{

3 study area were mostly trematodes ( flukes) .

j 2.2.1.11.5 Eqqs and Larvae '

Fish eggs are commonly classified as being buoyant, semi-buoyant, '

or demersal (on the bottom) (Ricker 1971) . The collection of

) eggs and larvae during the survey was done using surface and bottom plankton net tows and bottom pumping. These collection methods were used so that the three types of eggs would be

represented in the sampling. Eggs collected by plankton nets are most likely buoyant or semi-buoyant, and those collected by bottom pumping are primarily demersal. A limiting or complicating factor in the assessment of fish eggs and larvae in any area is that eggs and larvae may be concentrated in spawning

(

4 2.2-19

Brcidwood ER-OLS AMENDLENT 1 FEBRUARY 1983 areas rather than widely distributed. Tht: collection of adequate numbers of demersal eggs using traditional collecting methods was difficult, and the movement of fish between dif f erent bodies of lll I water (nuch as the Kankakee River and Horse Creek) made it almost impossible to define population boundaries during breeding pariods.

Fish eggs and larvae were collected during the first sampling period (May 2, 1974) at Transect 3, which indicates that spring opawning had already occurred by this time (see Table 2. 2-51) .

L;rvae were collected at Transect 3 as late as June 27, 1974, Thus, the spring spawning period started before May 2 and extended beyond mid-June 1974. Larvae collected during the first port of the sampling probably belonged to early spring spawners, whereas' eggs and larvae collected in the latter part of the curvey were from early summer spawners.

It is known that different fish species have different temperatures that induce spawning. For example, the spawning temperatures for rock bass, longear sunfish, and smallmouth bass have been reported tc be 200 to 210 C, 240 to 300 C, and 130 to 210 C, respectively (Scott and Crossman 1973) . It was therefore not unusual that fish eggs and larvae were collected throughout the sampling period.

Bottom plankton tows and bottom pumping produced a small number of eggs (15) and larvae (54) ; none were collected using surf ace pla nkton tows. the number of eggs and larvae collected per cubic meter of water at each sampling location is presented in Table 2.2-51. Although some larvae were collected at each transect, no eggs were obtained from Transects 2 and 5 during the entire sampling period (see Table 2.2- 51) .

More eggs and larvae were collected from Horse Creek (Tra nsect 4) during May 1974 than at all the Kankakee River transects (Transects 2, 3, and 5) combined, which suggests that spawning was more intensive in Horse Creek in May 1974 than in the Kankakee River at this time. Conditions in Horse Creek appear to te more ecologically favorable for early spawning than the Kankakee River conditions. Horse Creek is shallcw (mean depth of ,

4. 6 feet) , having relatively warm water (ranging between 2. 80 and 24.20 C during March through June) and low flow. Fish movements between the creek and the river were suggested from the observations made during the 1974 through 1975 study. Both the

, creek and some areas of the river appear to provide nurse xy l grounds f or eggs and larvae.

l 2.2.2 Terrestrial Environment 2.2.2.1 Jntroduction The 4454 acres of the Braidwood site included 1021 acres of cultivated fields, 471 acres of f allow fields, 395 acres of open 1 woodlands, and 2567 acres of strip-sine spoil. The ecology of 2.2-20 9

The flora and fauna observed during the baseline survey and their' :

interactions were summarized by indicating their relative !

positions within a generalized food web for the Braidwood site ,

(see Figure 2. 2- 28) . This food web schematic considered the site i

, as a .whole without distinguishing between the .various habitats .

! campled. It indicates general relationships between vegetation, '

herbivores, omnivores, insectivores, and _ carnivores found on the t site. Species grouped within boxes are generally similar in food preference, but a broad range of nutrient options may be represent ed. Although human beings are not included, it should be recognized that they are not only an omnivore in the web, but that they also influence the web by their effects on the habitat of . the individual species.

Initial ecological studies at the Braidwood site began in the fall of 1972 and continued on a seasonal basis during the winter, ;

spring, and summer of 1973. The results and projections of the j construction inpact concluded from these studies for the fall, t winter, and spring surveys are included in Subsections 2. 7.1 and ;

4.1.5 of the Braidwood Station Environmental Report - Con- l C'structionPermitStage (ER-CPS) . The impact was assessed in the .

ER-CPS and the Braidwood Final Environmental Statement (FES) . i The summer 1973 survey confirmed the minimal environmental impact i as described in both the ER-CPS and FES. t i

To augment the initial (1972 through 1973) baseline study, a >

program was designed for the 1974 through 1975 period. The .

, results and conclusions presented in the 1974 through 1975 Final I Terrestrial Monitoring Report further support the impact !'

assessment presented in both the ER-CPS and the FES. The information obtained during these 2 years of baseline monitoring ,

is summarized in the following subsections. [

2.2.2.2 obiectives of the 1972 through 1973 Baseline Survey I The major objectives of. the terrestrial baseline study (1972 ;

through 1973) were as follows: '

a. to record and describe "important" species of flora and f auna in the site area during all four seasons of -

2.2.2.3 obiectives of the 1974 through 1975 Baseline Survey The six major study objectives of the terrestrial baseline study (1974 through 1975) were the following:

a. to document existing biota in recently purchased areas that were not evaluated during baseline surveys;

b. to evaluate the biotic components of areas that will be subject to construction activity for station and switchyard facilities;

c. to observe annual fluctuation in the biological density represented within the site;

d. to expand the biological data base for predicting impacts associated within the site;

e. to provide background data for the initiation of a specific program to evaluate the impact of site development on migratory waterfowl; and

f. to identify significant parameters to be measured or monitored in later studies to provide continuing estimates of real and potential impacts.

.Long-term joint frequency distributions of wina direction and wind speed for each Pasquill stability class at Peoria (1966-1975) are suiamarized in Table 2.3-30.

2.3.5.4 Inversions and High Air Pollution Potential The 13 years of data (1952-1964) on vertical temperature gradients from Argonne (Moses and Bogner 196') provide a measure of thermo-dynamic stability, or mixing potential. Weather records from many stations in United States have also been analyzed with the objec-tive of characterizing atmospheric dispersion potential (Hosler 1961; Holzworth 1972) .

The seasonal frequencies of inversions based below 500 feet for the Braidwood Station. area are shown by Hosler as follows:

Inversions Below 500 Feet Percentage of 24-Hour Periods Percentage With at least One Season of Total Hours Hour of Inversion O snria9 Summer so 31 6>

81 1 Fall 38 72 Winter 28 48 Since northern Illinois has a primarily continental climate, inver-sion frequencies are closely related to the diurnal cycle. The less frequent occurrence of storms in summer produces a larger frequency of nights with short-duration inversion conditions.

Holzworth's data give estimates of the average depth of vigorous vertical mixing, which give an indication of the vertical depth of atmosphere available for mixing and dispersion of effluents. For the Braidwood Station region, the seasonal values of the mean daily mixing depths (in meters) are as follows:

Mean Daily Mixing Depths Season Morning Afternoon Spring 480 1500 Summer 320 1600 Fall 400 1200 Winter 470 610 0 2.3-21

BrCidwood ER-CLS When daytime (maximum) mixing depths are shallow, pollution potential is highest. g The following list presents Argonne data on the frequency of inversion conditions in the 5.5- to 144-foot layer above the ground expressed as a percentage of the total observations, and cn the average duration of inversion conditions:

Month Inversion Frequency First Hour final Hour Jan. 30.5% 5 p.m. 8 a.m.

Apr. 33.1% 6 p.m. 6 a.m.

Jul. 42.4% 6 p.m. 6 a.m.

Oct. 48.4% 5 p.m. 7 a.m.

Nocturnal inversions begin at dusk and normally continue until daylight the next day. The inversion frequency for January at Argonne compares well with Hosler's winter value, and the f all ceason shows a maximum in both Argonne and Hosler's data. Fall clso has the longest period of inversion conditions.

Holzworth has also presented statistics on the frequency of episodes of high air-pollution potential, as indicated by low mixing depth and light winds (Holzworth 1972) . His data indicate that, during the 5-year period from 1960 through 1964, Obe region .

I including the Braidwood Station experienced no episodes of 2 days Bh or longer with mixing depths less than 500 meters and winds less than 2 meters per second. There were two such episodes with winds remaining less than 4 meters per second. For mixing heights less than 1000 meters and winds less than 4 meters per second, there were about nine episodes in the 5-year period lasting 2 days or more, but no episodes lasting 5 days or more.

Holzworth's data indicate that northern Illinois is in a relatively favorable dispersion regime with respect to the low frequency of extended periods of high air pollution potential.

2.3.5.5 Topographical Description Figure 2. 3-22 is a topographic map showing the area surrounding the Braidwood Station. Figures 2.3-23 and 2.3-24 show topographic cross sections in each of the 16 compass point directions radiating from the site. It can be seen that the station, at an elevation of approximately 600 feet above mean sea level (MSL) is at one of the highest points within a 5-mile radius. The lowest points within 5 miles of the site are about 550 feet above MSL. Terrain in the vicinity of the Braidwood Station f alls of f except in the northeast clockwise through the south-southeast directions (see Figure 2.3-24) .

The site for the Braidwood Nuclear Generating Etation - Units 1 5 2 (Braidwood Station) is about 8 -

's southwest of the town of

~Custer Park,'which is on the K&.' r - Rivet. It is in a strip-mined region characterized by many water-filled trenches and ponds. Cooling water for the station is supplied by a cooling l pond that covers one of the strip-mined areas. The pond has a j normal pool elevation of 595 feet above mean sea level (MSL) with a surface area of 2537 acres or 3.96 square miles. The water

surf ace area constitutes 75% of the pond's total drainage area. of . 1 5.3 square miles. The pond is contained by dikes that all have a top elevation of 600 ' feet MSL except for one part of the dike just south of the station, which has a top elevation of 602.5 ,

feet MSL. The statAon grade elevation is 600.0 feet MSL. Site characteristics and changes to existing drainage features are ,

shown in Figure 2.4-1.

Granary Creek joins the Mazon River 1 mile southwest of the site, ,

and about 4 miles south of the station facilities at the north !

end of the pond. Crane Creek is a tributary of Granary Creek. '

Both creeks have an intermittent. water flow. According to records for watersheds.of similar configuration in the region (U.S. Geological Survey [USGS] 1961-1976), the average annual

, O . flow is 0.73 cubic feet per second (cfs) per square mile, or about 38 cfs for both creeks at the Kankakee-Grundy county line.

The estimated 100-year peak discharge is 3200 cfs at the same [

location. Figure 2.4-2 shows the drainage area of Crane and Granary creeks.

Horse Creek lies 2.5 miles east of the site at its closest point.

It has a drainage area of 148 square miles at its point of

discharge to the Kankakee River at Custer Park. The creek's !

t average annual flow is cbout 110 cfs, and its 100-year flood peak l

, is approximately 9200 cfs at its junction with the Kankakee !

River. l l

The Mazon River lies 5 miles west of the north end of the site. l A tributary of the Illinois River, the Mazon River has a drainage !

area of about 220 square miles at Mazon, 2 miles west of the site. The average annual flow at the gauge is approximately 134 cfs. The estimated 100-year flood peak is 13,600 cfs.

2.4.1.2 Kankakee River Basin Characteristics

, The Braidwood Station is on a low ridge southwest of the Kankakee River and east of the Mazon River. The Kankakee River joins the ;

Des Plaines River about 10 miles directly north of the site to

The K nkakee River watershed is shown in Figure 2.4-3. The Kankakee then flows northwestward 38 miles to join with the Des Plaines River. The Kankakee basin is 130 miles long and 70 miles wide at its widest point. The Kankakee River drains 5280 square miles, 2155 in Illinois and 3125 in Indiana. The maximum relief in the basin is 375 feet MSL between the mouth of the river and the high point of the drainage divide near valparaiso, Indiana. Low ridges of glacial origin define most of the drainage divide.

Within Illinois, the Kankakee River is 59 miles long, and has widths ranging from 200 to 800 feet and depths ranging from 1 to 15 feet. The total fall from the state line to the river mouth 10 127 feet. Channel slopes vary from less than 0.5 foot per mile to over 4 feet per mile. The channel slope in the site area io approximately 2 feet per mile. Most of the riverbed in Illinois is on or near bedrock. Relatively thin layers of sand cnd gravel overlie the bedrock with some small areas of silt.

There are two dams on the Kankakee River. One dam is at Wilmington, about 4 miles downntream from the intake point; the other dam is at Kankakee, about 15 miles upstream of the intake point.

The Wilmington dam is 11 feet high and forms a pool 2 miles long.

The Kankakee dam is 12 feet high and forms a pool 6 miles long. lll Both dams are constructed of solid concrete on bedrock. Neither dam is used for power production now although both dams were used for power generation at one time. There are no other control structures on the streams in the Braidwood Station vicinity (Barker et al. 1967).

The Kankakee River flow is gauged near Wilmington, 8.78 miles downstream from the Braidwood Station's withdrawal point and 5.5 miles upstream of the river mouth; the drainage area at the gauge 10 5150 square miles (USGS 1961-1976). The average flow rate for the Kankakee River at the intake is 3952 cfs. The corresponding elevation is 538 feet MSL and the average river velocity is 2.1 feet per second (fps).

Figure 2.4-4 is a bathymetric chart of the Kankakee River in the crea of the Braidwood Station's intake and discharge structures.

The data that were used to construct the bottom profiles shown in the figure were obtained from a hydrographic survey conducted by the Illinois Division of Water Resources Management (IDWRM) in April 1970 (Pitkin 1973) . The IDWRM study covered a 10-mile caction of the Kankahee River above Wilmington, Illinois; Figure 2.4-4 shows 7000 feet of that 10 ' miles.

Braidwood ER-OLS NOISE

({} 2.7 This section summarizes the ambient noise levels in the vicinity of the communities located within 5 miles of the Braidwood Nuclear Generating Station - Units 1 6 2 (Braidwood Station) .

Particular attention was also directed toward obtaining acoustic noise levels where high voltage transmission lines are located close to communities. All measurements were made keeping in mind applicable guidelines; i.e. , Illinois Environmental Protection Agency (Illinois EPA) , the U.S. Environmental Protection Agency (U.S. EPA) , and the Departmer.+ for Housing and Urban Development (HUD) . Noise effects in relation to adjacent occupancy are considered in Chapter 5.

2.7.1 Approach Ambient noise measurements were made at the village limits on the side towards the direction of the station. Where a transmission line ROW passes close to a community, the ambient noise measurements were also taken at the village limits on the side towards the direction of the ROW.

Thirteen communities (Braceville, Braidwood, Carbon Hill, Central City, Coal City, Custer Park, Diamond, Eileen, Essex, Godley, Harrisonville, Lakewood Shores, and Rest Haven) lie within a 5-mile radius of the Braidwood Station. They are identified in Figure 2.7-1. Three of the thirteen communities (Braceville, On Central City, and Coal City) are located within 1 mile of a transmission line ROW.

2.7.2 Procedures l In order to be compatible with federal and state noise standards, sound measurements were made with a Type 1 sound level meter while continuous samples of the ambient noise were being tape recorded during the day and night for periods of at least 20

minutes. Care was taken during the recording period to ensure tnat the recorded sample would be representative of the existing ambient noise levels.

The tape recorded data were analyzed to yield both the cumulative distribution of A-weighted ambient noise levels (see Figures 2.7-2 and 2.7-3) and the Leg, which is the A-weighted Equivalent Sound Level as defined by the U. S. Environmental Protection Agency ('U . S . EPA 1974). Leq represents the sound energy averaged over a 24-hour period; the day-night sound level (Ldn) represents the L with a 10 dB nighttime penalty. Ldn may be calculated fromb!ytime (a 15-hour period f rom 7:00 a.m. to 10:00 p.m.) and nighttine (a 9-hour period from 10:00 p.m. to 7:00 a.m.) Leg levels using the following relationships:

/ Ln + 10

_Q 3 Ldn = 10 log l_ 15f10 10 j+ 9 10 10 j [dB]

a Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 lll Where:

Ld = leg for daytime and Ln = Leq for nighttime.

2.7.3 Applicable Guidelines 2.7.3.1 Illinois Environmental Protection Agency Maximum allowable levels of environmental noise due to the Braidwood Station are established by " State of Illinois Noise Pol-lution Control Regulation", ef fective August 9, 1973, published by the Illinois EPA. This document identifies allowable levels based on the land use category of the emitter and the receiver. Noise emitted by the Braidwood Station (land use Class C) to residential areas (land use Class A) is limited by Rule 202 (Sound Emitted to Class A Land During Daytime Hours 7:00 a.m. to 10:00 p.m.) and Rule 203 (Sound Emitted to Class A Land During Nightime Hours, 10:00 p.m. to 7:00 a.m.). Maximum allowable octave band sound pressure levels of the more stringent Rule 203 are shown in Table 2.7-1.

This table also includes noise data measured at the village limits of the communities located within a 5-mile radius of the Braidwood Station.

2.7.3.2 U.S. Environmental Protection Agency The U.S. EPA has also identified a 24-hour Leg 170 dB as the level of environmental noise that will prevent any measurable hear-ing loss over a lifetime for all areas (U.S. EPA 1974). Similarly, undue interference with activitly and annoyance will not occur if outdoor levels in residential areGs are maintained at Ld n i 55 dB. Table 2.7-2 tabulates the Ld, Ln levels at the 13 village limits towards towards the Braidwood Station side and the 3 village limits towards the transmission line R0W side.

2.7.4.3 Department of Housing and Urban Development On July 12, 1979 HUD published " Environmental Criteria and Stand-ards, Noise Abatement and Control", 24 CFR Part 51 to encourage land use patterns for housing and other noise sensitive urban needs that will provide a suitable separation between them and major noise sources. HUD criteria state that noise levels for residen-tial developments are normally acceptable if they do not exceed a Day-Night average sound level of 65 dB. A Day-Night average sound 1 level, abbreviated as DNL and symbolized as Ldn, is the 24-hour average sound level in decibels, obtained af ter addition of 10 decibels to the sound levels in the night from 10 p.m. to 7 a.m..

Table 2.7-3 tabulates the Ldn levels at the 13 village limits towards the Braidwood Station side and the 3 village limits towards the transmission line ROW side.

For example, while the major materials of construction are concrete and steel, colored metal siding is employed as part of the architectural treatment to provide variety of texture as well as color. The siding is used on the entire turbine building and on the tendon enclosures of the reactor buildings. The structures are physically contiguous to each other; the grouping provides a balance and symmetry of design and a pleasing variety of roof and corner lines.

3.1.4 Release Points The release points for gaseous ef fluents are through vent stacks located on the auxiliary building roof. The vent stacks, described further in Section 3.5, extend above the turbine building to about 200 feet above the plant grade. The Unit 1 vent stack is located at Universal Transverse Mercator (UTM) coordinates 4,565,265 meters north and 396,950 meters east. The Unit 2 vent stack is located at UTM coordinatec 4,565,250 meters north and 396,950 meters east.

The release point for liquid effluents is the blowdown discharge structure on the west bank of the Kankakee River at an elevation of 536 feet above mean sea level at UTM coordinates 4,565,887 meters nortn and 403,568 meters east.

! FEBRUARY 1983 3.4' HEAT DISSIPATION SYSTE_M 2

During the operation of the Braidwood ' Nuclear Generating 1

Station - Units -1 5 2 -(Braidwood Station) ,- the condensers and j other heat exchanse equipment require cooling water. This water 4 is taken from the cooling pond shown in Figure -3.4-1 and circulated through'the various cooling equipment; the heated

~

l This closed-cycle i effluent is then returned to the cooling pond.

l cooling pond serves as the heat sink to dissipate most of the' j waste heat to the atmosphere. This heat is dissipated by l

evaporation and by convective, reflective, and sensible heat

transfer mechanisms.

q l The cooling pond has an overall area of about 3540 acres, with a j water surf ace area of 2537 acres. Approximately 301 of the total 1 pond area is occupied by islands. The maximum depth of the pond is about 15 feet, and it has an average depth of about 9 feet.

' Figure 3. 4-1 indicates the general layout of the pond.

Earthen dikes having a width of 14 feet at the top form the j

j boundary of the pond. The top elevation of most of the dikes is 600 feet above mean sea level (MSL), 5 feet above the nornal pond pool level of 595 feet MSL: the only exception, a portion of the dikes just south of the plant, has a top elevation of 602.5 feet '

MSL. Interior dikes have been included in the design of the Braidwood Pond in order to assure that With the maximum utilization of

() the pend cooling surface is attained. the interior dikes, the possibility of channeling or short circuiting of the warm t l water through portions of the pond .is reduced to a minimum, and

' the cooling performance of the pond is improved. The layout of these internal dikes is shown in Figure 3.4-1. With the arrangement of the pond, no recircu]ation effects that would be detrimental to the performance of the pond are anticipated. l I channeling does occur in the Braidwood Pond due to stagnant water 4

in deep or side-arm regions, thus~ shortening the residence time of heated water in the lake. This channeling was considered in

the lake performance analysis by using only the effective area and volume instead of total area and volume.

4 i Significant vertical stratification of temperatures and f velocities in the pond is expected to occur only in those regions that are deeper than the 10-foot depth of discharge.

The cooling pond is supplied with makeup water from the Kankakee l

2 River to compensate for losses due to evaporation, seepage, and l blowdown. This makeup water is withdrawn from the river at an expected rate of 90.8 cubic feet per second (cfs) by means of a i

river intake structure illustrated in Figure 3.4-2. The intake i structure operating floor is located at elevation 557 feet above

' mean sea level (MSL), which is above the 1975 flood (flood of

! record) elevation of 552 feet MSL. The mean annual flow and 1-() day low flow of the Kankakee River at the intake are 3640 cfs and 3.4-1 l

Braidwotd ER-OLS 487 cfe, and the corresponding water surface elevations are 538 and 534 feet MSL. h The intake structure houses threc intake pumps; two pumps of 53.5 cfs capacity are used to supply water for normal operation and a third pump of the same capacity serves as a standby and is used :

for pond filling. The velocity at the river intake structure is between 0.32 and 0.48 feet per second (fps) based on two-unit opera tion.

At the river intake structure the water flows through bar grills and vertical traveling screens to remove debris from the intake water. The debris removed from the screens is disposed of off the site by an independent contractor.

The blowdown from the cooling pond is released to the Kankakee River f rom a discharge structure illustrated in Figure 3. 4-3.

Flow control is provided on the blowdown line so that flow may be terminated when both units are shut down or are being refueled.

The location and orientation of the blowdown discharge and the river intake structures are shown in Figure 3.4-4. The orientation of the discharge is approximately perpendicular to the river shoreline. The river intake structure is approximately 2000 feet below the confluence of Horse Creek with the Kankakee River, and the discharge structure is about 500 feet below the intake structure. The discharge is returned to the river at a nuximum velocity of 4.3 fps and at an incressed temperature, which varies seasonally. Table 3.4-1 shows the mediaa monthly lll temperatures load factor.

for the blowdown with both units operating at 100%

The predicted blowdown temperature ranges frcm 490 F in January to 880 F in July.

Tss a result of the discharge of the blowdown into the flowing Kankakee Piver, a thermal plume is established downstream whose detailed temperature profile depends on river conditions and the blowdowr. characteristics. A discussion of the extent and effect of this plume is in Section 5.1; a description of the model used to estimate these parameters is in Appendix 5.1A.

Three vertical dry pit circulating water pumps per unit draw water f rom the cooling pond through a pond screen house near the pum ps (see Figure 3. 4-5) . At the pond screen house the water flows through bar grills and vertical traveling screens that remove debris from the intake water. The debris removed from the screens is disposed of off the site by an independent contractor.

The water is pumped through a 16-f oot diameter pipeline to the condensers, then through another 16-foot diameter pipeline to the discharge outfall structure and back into the pond. The Braidwood Station condenser cooling water requires a continuous flow of about 3250 cfs for the two units. This water is withdrawn f rom the cooling pond and returned there with a temperature rise of about 220 F. The total heat dissipated to the condenser cooling water is approximately 1.6 x 1010 Btu /hr for the two units. llh 3.4-2

The expected sources are given in Table 11.1-6 of the FSAR. These drains include pump baseplate drains in the auxiliary building, reactor coolant 1:akages, pump seal and stuffing box leakages, valve stem packing leakages, and other equipment overflows or spills. Inputs also include waste from operations such as washdown and equipment maintenance. These floor drains collect in two 8000-gallon tanks that are shared by both units. After sampling, the waste is filtered and evaporated.

3.5.2.2.8 Laun dry Drains Laundry wastes are collected directly f rom the laundry facilities of the two units. The expected average daily flow for this cubsystem is 1400 gallons, with a maximum daily flow of 4000 gallons for both units. The expected activities are given in Trble 11.1-6 of the FSAR. The laundry wastes are collected in one 4000-gallon tank and two 2000-gallon tanks. After sampling, the waste is filtered and evaporated. Because of potentially high carryover due to the detergent, the laundry waste will be processed separately from other wastes.

3.5.2.3 Liquid Radwaste Dischargee All liquid wastes to be released are analyzed f or gross beta, llh gamma, and tritium activity in one of the five 20,000-gallon monitor tanks after thorough mixing by recirculation. The liquid in then pumped to the 30,000-gallon release tank where a sample io again analyzed for gross beta, gamma, and tritium activity.

B sed on this analysis, a discharge rate is determined so that, when mixed with circulating water blowdoen, tne water leaving the plant has a radioactivity level less than the applicable MPC as ctated in 10 CFR 20. A key-locked switch may then be manually opened so that water can be discharged. The key for the valve lock is controlled by administrative procedures.

Ao a further backup, a radiation detector monitors the discharge line before the discharge is mixed with the cooling pond blowdown line. Upon detecting an abnormal level of radiation, a valve on the release tank line immediately ahead of the mixing point closes and an alarm signal is relayed to the control room.

Records are maintained of all radioactive wastes discharged to the environs to verify that radioactive releases conform with the requirements of 10 CFR 20 and 10 CFR 50.

Liquid radwaste releases were calculated using the PWR-GALE computer program and the parameters listed in Table 3.5-5.

Expected annual activity releases to the discharge canal are given in Table 3. 5-3. The radiological impact of these releases 10 discussed in Section 5.2.

Under all plant operating conditions, a radiation detector in the exhaust vent continuously monitors the radioactivity level of the exhaust air before its release to the atmosphere. At high radio-activity levels, this detector sounds an alarm in the main control room and alerts the operator to initiate corrective action.

3.5.4 Solid Radwaste System 3.5.4.1 Objectives and Design Basis The Braidwood Station solid radwaste system is designed to receive, dewater, solidify with cement, seal in a 55-gallon drum, and tempo-rarily store the following wartes: demineralizer bead resins, evaporator concentrates, and scant filter cartridges. The system also receives, compacts, and temporarily stores radioactive dry wastes produced during station operaticn and maintenance. Evapora-tor concentrates and dry active waste (0AW) residue can also be solidified by polymer af ter being processed by the volune reduction i lll system. Closed-top drums approved by the U.S. Department of Trans-portation (00T) are used for packaging solidified wastes, and DOT-approveo open-top drums are used for packaging dry sclid wastes.

The expected ar.nual weight, volume, ano activity of solid radwaste shipped from the Braidwood Station appear in Table 3.5-8, which gives values both with and without the use of a volume reduction i system. Packaged radioactive solid wastes are shipped off the site and buried in accordance with applicable Nuclear Regulatory Commis-sion (NRC) and DOT reguations. The system is designed specifically for a 40-year service life, maximum reliability, minimum mainten-ance, and minimum exposure to station personnel and the general public. The expected solid radwaste system output is 5760 to 6910 drums per year if the volume reduction system is not operatiunal 1 and 900 to 940 drums if it is.

3.5.4.2 System Description Operation of the solid radwaste system is indicated in Figure 3.5-4 of the ER and Figure 11.4-7 of the FSAR. Table 11.4-1 of the FSAR 1 lists the process equipment and storage design capacities. A more detailed system description is given in the Braidwood Final Safety Analysis Report (FSAR) Subsections 11.4.2 and 11.4.3.

Two separate fill nozzles are provideo, one for spent resins and one for concentrated waste.

A scale and a radiation monitor provide drum weight and activity level readouts on the control console after removal from the drum processing-unit.

3.5.4.2.4 Orum Handling Equipment This equipment includes three remotely operated cranes with tele-vision cameras for visual surveillance, two drum transfer cars, and a filter-cartridge transfer vehicle. The cranes are used to trans-port preloaded drums to the drumming station, remove and position drums on a scale, transport and position sealed drums in either high or low-level storage, and retrieve and transport tham to trucks for of fsite disposal. The drum transfer cars transport drums between the process units and the storage area. The filter cartridge transfer vehicle transpcrts drums containing spent filter cartridges frcm the filter area to a place where the drums may be placed on the drum transfer car.

3.5.4.2.5 Smear Test and Label Station lh This station consists of a mator-operated turntable setdown posi-tion for drums behind a small shield wall equipped with access plugs and working tools to accomplish remote lebeling, smear test-ing, and radiation monitoring of all external surfcces cf sealed drums before offsite disposal.

3. 5. 4. 2. 6 Dry Waste Compactor The dry waste compactor compresses paper, fabrics, plastics, and other wastes into 55-gallon drums. A large-diameter, pneumati-cally-powered ram drives the platen down into the drum. During compaction, a safety shield encloses the loading areas above the drum and protects the operator from debris that might escape. An air filtration assembly maintains control of contaminated particles during compactor operation. Radioactive dust is captured by means of a roughing filter and two HEPA filters operating in parallel.

The filtration system is interconnected to the plant radioactive vent system. The radioactivity of most of the dry waste is low enough to permit manual handling.

3. 5. 4. 2. 7 Volume Reduction System The major components of this system are a fluidized beo dryer, a dry waste processer, a gas-solids separator, a condenser, two 3.5-18

Response

There are four U-tube recirculating type steam generators with a O- carryover fraction as specified in NUREG-0017, April 1976, of 0.001 for non-volatiles and 0.01 for iodines.

Request:

2. The total steam flow (lb/ hr) in the secondary system.

Response

The total steam flow in the secondary system is 1.51 x 107 lb/hr.

l Request:

3. The mass of steam in each steam generator (1b) at full power.

Response

There are approximately 9000 lb ot steam in each steam generator at full power.

P Braidwood ER-OLS AMENDMENT 1 i FEBRUARY 1983

Response

Th re are approximately 117,000 lb of liquid in each steam g;narator at full power.

Request:

5. The total mass of coolant in the secondary system (1b) at f ull power. For recirculating U-tube steam generators, do not include the coolant in the condenser hotwell.

Rorponse: -

Thn total mass of coolant in the secondary system is 2.02 x 106 lb at f ull power.

R quest:

6. The primary to secondary system leakage rate (lb/ day) used in the evaluation.

Response

The primary to secondary system leakage rate is 100 lb/ day. 1 Request:

7. Description of the steam generator blowdown and blowdown purification systems. The average steam generator blowdown rate (1b/hr) used in the applicant's evaluation. The parameters used for steam generator blowdown rate (lb/hr) .

Response

The purpose of the steam generator blowdown subsystem is to pro-vide the means for controlling the water chemistry in the steam generators. Normally, the st.eam generator blowdown is non-radioac tive , and a blowdown rate of 60 gpm (86,400 gal / day per unit) is sufficient. For purposes of conservatt=A, however, the design of the blowdown subsystem is based on a continuous 1 gpm primary to secondary leak for 14 days. During leak conditions, cecondary water becomes radioactive and will reach an isotopic

, inventory equilibrium inversely proportional to the blowdown

! rcte. The higher the blowdown rate, the lower the radioactive content of the secondary water. With a gross radioactive leak, therefore, blowdown is increased to 135 gpm (194,400 gal / day per unit) .

Blowdown is cooled through two blowdown condensers, one per unit, th;t are crosa-tied. The cooled blowdown liquid is filtered and th3n demineralized.

Braidwood ER-OLS The formation of monochloramines (Equation 3.6-3) takes precedence over zhat of di- and trichloramines and is generally 4

instantaneous. The chloramines formed are present as

, monochloramines due to the small ratio of HOCl to NHa. The chlorine in chloramines still retains about half of its oxidizing i'

potential and is still effective as a bactericide. The reaction rate of chloramines, however, is lower than that of HOCl.

The small concentrations of chloramines formed and the residual

! chlorine present are not expected to persist in the water for j

three reasons. First, the circulating water contains bacteria that assimilate the residual chlorine and chloramines of the i nonessential service water. The residual chlorine and

] chloramines of the essential service water are assimilated when combined with the blowdown from the essential cooling pond, which will still contain bacteria. Second, part of the volatile

chloramines are lost due to evaporation. Third, while retaining

! their oxidizing potential, HOC 1 and chloramines react with and are destroyed by reducing agents like S=, Fe++, and Mn++, as shown in the following equations:

H,S +,4HOCl - HaSO,+ 4 hcl (3. 6-6) i 2Fe (HCO 3 ) , + HOCl + hcl + Ca (HCO 3) ,-*2Fe (OH) 3 + CaC1 2 + 6CO, +H0 (3.6-7)

MnSO, + HOCl + hcl + 4NaOB-a-MnO, + 2 Nacl + Na SO, + 3HzO j O ( 3. 6- 8)

Since there is no accurate way to predict the chlorine demand of the pond, the exact quantity of NaOCl used 10 impossible to i predict. The feed rate is carefully monitored. The service 1

water, which may have a small residual chlorine content af ter chlorination, is returned to the cooling pond. Since the

condenser cooling water is chlorinated after the blowdown take-

! off point, chlorine concentration at the point of blowdown

discharge is negligible.

i j 3.6.2 Makeup water Treatment System j Surface water from the cooling pond is used to supply the makeup i water required for the steam cycle. As shown in Figure 3. 3-1, j the water is passed through a chlorine retention tank,

clarifiers, and a clear well. From there the water passes j through threc parallel sand filters. Each filter operates at 3.0 j gpm/ft2 during normal operation and a maximum of 4.5 gpm/fta when j one filter is out of service. After each use, each filter is j backwashed for 5 to 10 minutes, using 1000 gpm of filtered water ,

j for each filter. The filtered water is stored in a 150,000 j gallon tank.

Three filtered-water transfer pumps (one a spare) supply water to i the domineralizer trains for treatment. There are two identical

O v

demineralizer trains, each capable of producing a net daily average of 150 gpm. Each train consists of, in order, a primary, l

3.6-3

Braidwood ER-OLS AMENDMENT 1 '

FEBRUARY 1983 llh strong-acid cation unit, a secondary, strong-acid cation unit, a cock-base anion unit, a strong-base anion unit, and a mixed bed unit. After treatment, the water goes to the condensate storage tank or primary storage tank.

3. 6. 2.1 Regeneration Wastes After a quantity of water has been processed through the demineral-izor train, the ion exchange resin is exhausted and needs chemical regene rati on. Regeneration of the exhausted resins may take place once each day. During regeneration, which lasts about 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , the only chemicals added are sulfuric acid (H SO 2 4) and sodium hydroxide (NaOH). Each regeneration require 2240 pounds of 93%

H2 S0; and 792 pounds of 100% NaOH for regeneration and neutral-ization. The 70,095 gallons of waste produced during each regener-ction are routed into the circulating water flow.

3.6.2.2 Filter Backwash Effluent The makeup filter subsystem consists of three parallel sand filters and carbon filters. Each filter is backwashed once each day with water from the filtered water storage tank. The backwash water contains dissolved solids and suspended solids that are collected during the filtering process. The sand filters are backwashed each day for a 10-minute period at a rate of 1.9 cubic feet per second g

(cfs), and the carbon filters are backwashed each day for a 10-min-uto period at a rate of 0.76 cfs. The discharge from this back-eashing operation is routed to the waste treatment building.

3.6.3 Waste Treatment Treatment consists of an oil separater, an agitated equalization basin, a-Quadricell separator, and filtration, after which the clean water effluent is routed to the circulating water system.

l The oil separator is equipped with skimmers to remove oil. The skimmed oil flows to a waste oil nolding tank. The waste oil is disposed of, as necessary, by a licensed contractor in an approved 1 I manner. (

Sludge from the Quadricell is pumped by sludge transfer pumps to sludge drying beds. Underflow from the beds is pumped by underflow pumps to the equalization tank. The dried sludge is scraped off and hauled away by a licensed contractor for disposal in a certi-fled landfill site.

3.6.4 Potable Water System The volume of water uced for potable and sanitary purposes is small (about 15,000 gallons per day [gpd]) in comparison with other plant ggg 3.6-4

uses. Water-is taken from the filtered. water storage tank. ~The water is chlorinated with hypochlorite, which.is. fed at a rate -

proportional'to the flow rate. .The chlorinated water is then stored for potable and sanitary use.-

All' sanitary wastes are treated in a sewage treatment system of

-approved design (for.further details see Section 3.7). The dis- i charge from the sewage treatment plant is . continuously chlorinated, as indicated in Section 3.7, and is discharged with the cooling '

pond blowdown. The chlorine dosage is-usually 3 to 10 mg/ liter.

1 This dose results in a free' residual chlorine concentration of about 0.5Lppm. .After mixing with the cooling pond blowdown, the 5 chlorine concentration is negligible. )

3.6.5 Ra.dwaste System i

The discharge from the radwaste system is high-purity distilled i water. The radwaste plant receives and decontaminates wastes that ;

result from the operation of the-nuclear reactors. -After the nec- '

essary decontamination, the liquid ef fluents 'are batch discharged ;

to.the cooling pond blowdown. Section 3.5 discusses the radwaste system in detail. t

() Table 3.6-2 shows the estimated effluent analysis, and Table 3.6-3 the average' analysis, of the final discharge, which in both' cases f

meets all Statelaf Illinois effluent standards. !

\ ,.

. Figure - 3.9-l'shows the transmission connections .for the Braidwood

~

! Nuclear Station. _'These consist of-existing double circuit.345 kV

! lines. connecting to the LaSalle County Generating Station and the

! East Frankfort Transmission Substation and of a double circuit 345 j kV line constructed.on new.right-of-way (ROW) to an existing linc on the property of.the Crete Transmission Substation. One. circuit

of- the double circuilt 345 kV: line will connect to the Bloom Trans-3 mission Substation with an intermediate connection at the Davis i Creek Substation. The other circuitJwill connect to the Burnham

. Transmission Substation. No connection will be made to the Crete Transmission Substation.

Figure 3.9-2 shows the~ detailed route of the new line from the _

. Braidwood Nuclear Generating Station - Units 1 and 2 (Braidwood j Station) to the existing Crete 1 Transmission Substation. This route j traverses approximately 55 miles and crosses nearly flat agricul-

tural land of' low relief. A 330 foot ROW that includes space for a l double' circuit 345 kV line and a future 765-kV line comprises the

[

i first 7.3 miles. The next 15.6 miles' is, in general, also 330 feet wide and accommodates a four circuit 345/138 kV transmission line and, for the most part, a future 765 kV line. 1

In Section 36 of Rockville Township in Kankakee County, the four-

! circuit construction terminates at the Davis Creek Transmission Substation. The double circuit 345 kV line continues north for 7.4

- miles on a 315 foot wide ROW that can also accomodate a future 765 kV line. The next 17 miles between Wilton and Washington Townships i involves a 180-foot widening of an existing 200-foot R0W. This i 380-foot R0W will have a double circuit 345 kV line parallel to and l with structures opposite those of an existing 765 kV line. From Washington Township 7.75 miles northward to the Crete Substation, a

!- new 235-foot ROW will accommodate a double circuit 345 kV line and

! a future four circuit 138/345 kV line (see Figure 3.9-2) . Struc-

! ture types for the 55 mile transmission line will be similar throughout, single shaft structures for tangent and light angles ,

i (up to 130) and lattice steel towers for angles over 130 The

single shaft structures will normally not exceed 6 feet in diameter at the ground;line. All tangent structures will either be direct i- -embedded in soil with granular or concrete backfill or will have

' poured concrete foundations. The tower foundations will normally

. be 3 foot diameter poured concrete belled caissons on each of the four legs of the towers.

All sections of the line will average no more than six (6) struc-turss per mile. Figure 3.9-2 shows the route and structure pro-files for this line.

Th3 route crosses through nearly 48 miles of cleared farmland, 3.38 miles (129 acres) of open woodland and hedge rows, and 2.75 miles (105 acres) of riparian woodland. The lines cross the Kankakee 1 Rivar approximately 7 miles northwest of Kankakee, Illinois.

Eleven (11) creeks and eighteen (18) intermittent streams are also crossed. Transportation route crossings include the Norfolk &

Wsstern; Illinois Central Gulf; Chicago, Milwaukee, St. Paul &

Pccific; and Chicago and Eastern Illinois Railroads, one interstate highway, two U.S. highways, and four state roads (see Table 3.9-1).

3.9.2 LINE DESIGN PARAMETERS The transmission line will be constructed to meet or exceed all requirements of'the Illinois Commerce Commission General Order 160, which is identical to the National Electric Safety Cor.e for the construction of transmission lines. Electrically, the line is designed to minimize adverse effects to the general public. The insulation used for this line will be equal to or greater than that which is common practice in the electrical utility industry. The conductor diameters will be in the range that results in low corona, audible noise, and electrical noise. Wires to be used for lll this line are one 2156 MCM ACSR (84/19) conductor per phase and one 7#8 alumoweld static wire per circuit. Each conductor is rated 2300 amperes (summer normal) and 2900 amperes (summer emergency).

3.9.3 EXISTING SUBSTATIONS AFFECTED The transmission substations affected are the Bloom Transmission Substation located east of Chicago Heights, Illinois, in Section 27 of Bloom Township in Cook County, Illinois, and Burnham Transmis-sion Substation located in Burnham, Illinois, in Section 6 of 1 Thornton Township in Cook County, Illinois. Both substations con-tain 345 kV to 138 kV transformers and no new 345 kV terminal facilities will be added to accommodate the Braidwood transmission lines.

3.9.4 RADIATED ELECTRICAL AND ACOUSTICAL NOISE The diameter of the conductors used will be in the range that re-sults in low corona, audible noise, and electric noise. Although engineering has not been completed on the transmission line, it is anticipated that the same engineering criteria used on past dcsigns, resulting in few problems, will be duplicated or improved for this transmission line.

3.9.5 INDUCED OR CONDUCTED GROUND CURRENTS

Induced or conducted ground : currents .can become a significant f ac-tor Lin urban areas where extensive networks of pipes and cables j have been placed underground. .The magnitudes of currents induced i

, into-such underground networks are. dependent-upon the current in j the overhead transmission lines, the distance above the ground, the ;

l soil-~ characteristics, and the extent of parallelism between the

' transmission-lines _and the underground' equipment. Also, during i high_ ground fault conditions, present designs are such that the ;

entire. fault current does not~ pass through the ground. High speed l relays at the substations operate to render such situations highly l transient,-reducing the potential corrosion due.to the " battery ;

t effect". (The soil can serve as as an electrolyte between the l transmission ground'and the underground equipment of other sys-tems. As with conventional' batteries, corrosion of:these "ter- :

minals" could. result.). A complete analysis of these problems can- ,

not be made until the load currents have been determined and load i flow studies have'been completed.

3.9.6 ELECTROSTATIC FIELD' EFFECTS 1

. Electrostatic fields are present at any voltage level.- The field !

strength is dependent upon voltage, height of conduct, and distance i from the centerline of-the support structure. Past installations i of.138 kV and 345 kV lines have proouced few if any complaints.

Introduction of 765 kV lines, however, has caused review of these l

4

-effects _and explanations to the public of the electrostatic fields t under these lines. The intensity of the field can be calculated i before installation ano actually checked by measurement after in- [

sta11ation. Past experience has shown calculated values to have !

been conservative. Based on these conservative' calculated values, !

the 345 kV lines, either independently or in conjunction with 138 !

kV lines, are not expected to cause significant electrostatic ef- t fects. Where the 345 kV lines are to be placed parallel to an ;

4 existing 765.kV lines, calculated values show that the field in-tensity is-increased slightly in some areas and actually decreases

.in other areas. In either case the incremental difference is so slight as_to be hardly measurable. It is planned to measure the f field strength before installation and again after installation of !

the 345 kV lines for comparative analysis. As in the past, CECO. l

, will work cooperatively with landowners to mitigate or correct any I 2 -adverse effects caused by the electrostatic field. Corrective

measures will be in accordance with the following paragraphs. i 1 I I . Fences and other fixed metallic objects in and along transmission !

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 indicate that the eletrostatically induced drain current would Oxceed the minimum level of perception (approximately 1 milli-cmpere) of a person touching the fence or metallic object.

Induced voltages on electric fences are drained by the installation of drain coils at appropriate intervals. The grounding technique for non-electric fences on wood posts is to install steel posts at 1 cppropriate intervals and connect the fence to them. Fences on steel fence posts do not need additional grounding.

With respect to mobile equipment, the ground clearance of the 345 kV lines will be such that under all conditions the current due to electrostatic ef fects will be less than 5 mil 11 amperes, rms, if the largest anticipated trucks, vehicles or equipment operated under the lines were short circuited to ground.

3.9.7 OZONE PRODUCTION The generation of gaseous effluents as a result of corona activity on extra high voltage (EHV) transmission lines has been raised as an environmental issue. As a result, CECO. engaged the services of an outside consultant to determine the validity and magnitude of the ozone effect.

g Since the ozone has only recently been recognized as a potential pollutant, some background information on the substance may be helpful. Ozone (03 ) is 50% denser than oxygen (0 2 ) and is a very reactive compound. It is formed naturally in three ways:

High in the atmosphere, oxygen reacts with ultraviolet sunlight to form ozone, which circulates to lower altitudes as a result of weather. Sunlight reacting with airborne pollutants can also create ozone. Finally, lightning and other high voltage discharges cause oxygen to disassociate and recombine to form ozone. Gener-ally, the ambient ozone level is proportional to the strength of the sunlight, increasing during the day and decreasing during the night. North winds, however, also bring in ozone from the Arctic.

It is possible for high voltage transmission lines to produce ozone if they have high voltage discharges (corona). The U.S. and Illinois Environmental Protection Agencies have set an air quality standard of 8 parts per 100 million as the maximum 1-hour concen-tration, which is not to be exceeded more than once per year.

A field test program has been completed on the CECO. system. the l program provides comparative data for three locations: (a) remote l from high voltage transmission lines for the ambient ozone level of the area; (b) adjacent to a 345 kV switchyard; and (c) on the ROW of the existing 765 kV transmission line presently in operation on the CECO. system.

The automatic recording _ instruments at the three locations were rotated to' provide the highest possible reliability for comparitive readings.

.Instrbments-that recorded temperature, dew point, wind direction ,

and. velocity and barometric pressure were installed at the ambient location. The weather data obtained were similar to that taken by

the Weather Bureau at-O' Hare Field. Therefore, the O' Hare weather i information was used for this study.

~

The results of the test program show that transmission lines have no measurable effect on the ozone present in the atmosphere. These results are published in final report form under IEEE Paper T 74 i' 057-6 " Field Investigation of Ozone Adjacent to High-Voltage Trans--

J mission Lines" TBrabets and Fern 1974).

3.9.8 ENVIRONMENTAL IMPACT

! It is CECO's policy to choose transmission line routes that have the least environmental impact. Since most of the- R0W's run through nearly flat and already cleared agricultural land or along an existing transmission line R0W, very little new clearing will-be ;

O necessary. Woodland will be clearned only to the extent necessary L

U to maintain transmission security. No long term disruption to the

, wildlife of this region is expected since R0W's are ecologically suited to a mixed type of habitat (hedgerows, open woodland, and I

cultivated fields) .

The more sensitive areas are the riparian zones along the Kankakee

, River and the intermittent marshland areas. The riparian zone at the crossing of the river is approximately 7.5 acres. The marsh-lands are small.and discontinuous and can be spanned by the li:.es.

3 Care will be taken in the placement and construction of the struc-

, tures in these areas so that impact on the existing biota is not

expected to be significant.

1

! The aesthetic impact of these transmission lines has been a major consideration.in choosing the R0W location. Placing lines in cul-tivated fields-in order.to reduce the biotic impact that would result from placement in wooded or. marsh areas necessitates an i L unavoidable visual impact due to the extensiveness of the already

cleared agricultural areas. Viewing exposure in these areas, how- .

ever, is expected to be-limited to the low density transient and local-populations. Most of the highways will be crossed at acute

. angles and at no time is a R0W adjacent and parallel to a primary rohd. By paralleling existing transmission whenever pnssible, the visual impact of the new transmission line will be greatly reduced.

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 g

Visual impact will also occur whe~re the line crosses the Kankakee River. Scattered residential communities are located all along the river. The close proximity (0.25 mile) of the Braidwood to Crete ROW to the southern end of the Kankakee River State Park is not oxpected to produce a significant visual impact. The immediate crea is not influenced by residential communities and visitor view-ing from within tha park is largely blocked by open woodland vege-totion.

The environmental impact of induced or conducted ground currents associated with the transmission of electric power from the Braiowood Station is expected to be very little because the trans-mission line ROW passes through mainly agricultural areas. The donsity of underground piping or cable systems existing in these creas is expected to be low, thereby minimizing the potential for induced or conducted ground currents.

It is CECO's policy that no building remain on the R0W. With the use of angle towers most of the buildings can be bypassed, thereby averting residential disruption. The route selection process in-cludes considering the areas where the least amount of residential disruption will occur. In the few cases where the buildings cannot be avuided, the residents may choose either to have CECO. relocate their structures or to have CECO. pay the owners due compensation

~

g for their residences.

9.9 ENVIRONMENTAL CONSIDERATION

S OF TRANSMISSION ROUTING Tne transmission system associated with the Braidwood Station will be routed over agricultural land for the majority of its distance.

There are several smaller areas of either pure forest lands or mixed forest-field areas. In those areas where agricultural land is crossed, farming will be possible on the R0W af ter the erection of the structures. Those areas of forest where trees will have to be cut will be small, and the procedure will use proven techniques to selectively eliminate only that vegetation necessary for struc-ture and line clearance and safety. Erosion will be kept to a

minimum by using existing elevation grades along the routes, locat-1 ing structures in crrek areas well back from bank edges, and re-garding techniques. Special consideration will be given during construction to allow only minimal environmental degradation.

$ 4.1 SITE PREPARATION AND PLANT CONSTRUCTION 4.1.1 Construction Schedule A Nuclear Regulatory Commission (NRC) construction permit for the Braidwood Nuclear Generating Station - Units 1 and 2 (Braidwood _

Station) was issued on December 31, 1975. As of July 1, 1982, 61%

of the estimated $1.6 billion capital cost had been expended.

4 Completion dates for Units 1 and 2 have been set for October 1985 1 7

and October 1986, respectively. The specific conditions for envi-

! ronmental protection attached to the contruction permits are listed in Section 4.5.

The effects of site preparation and construction activities on land and water use are described in the following subsections.

4.1.2 Land Use In the development of the 4454 acre Braidwood Station site, 130 acres are affected for actual plant building activities, including O 35 acres of woods and 70 acres of cultivated fields that will be changed during the life of the station from current use. There are

also 25 acres of fallow fields within the station construction area. After building construction is completed, 20 acres will be i occupied by permanent physical structures (Edmonds 1974).

I The exclusion area around the station and switchyards includes

. approximately 300 acres, of which 120 acres are wooded. Approxi-

! mately 35 acres of open woodland will be cleared for construction.

l The other 85 acres will remain standing. This limited clearing will maintain the availability of biotic cover in the Braidwood Station site area (Edmonds 1974).

) Aerial photographic measurements conducted by Westingnouse Environ-1 mental Systems Department (WESD) during initial site surveys in-dicated that the proposed cooling pond will encompass 3540 acres, 4

and construction will affect 704 acres of cultivated land, 301 acres of fallow-field vegetation, 222 acres of woods and 2313 acres of strip-mine spoil. Subsegurnt Commonwealth Edison Company (CECO) projections indicate that af ter the completion of mining in the area, the affected pond area is expected to comprise 2838 acres of strip-mine spoil, 204 acres of fallow fields, 117 acres of woods, and 381 acres of agricultural fields. Approximately 784 acres i l within the site will not be affected by station construction (Edmonds, 1974).

occupied where selective competition will take place for New habitats attractive to aquatic biota such as frogs, turtles, and some water fowl will be formed.

The Praidwood Station site is served by both highway and rail trensportation facilities.

Interstate SS is less than 2 miles west-northwest, and Illinois State Routes 53 and 129 are less than a mile northwest of the station. The Illinois Central Gulf Railroad, which runs parallel with and between Routes 53 and 129, is used to provide spur track access from the site to the main line.

The initial site preparation work has two stages. The first stage consists of stripping, excavating, and backfilling the areas occupied by structures and roadways. The second consists of developing the site with all necessary facilities to support construction, such as offices, railroad tracks, warehouses, wells, sanitary facilities, and power lines. The actual station construction began while these activities were in progress.

To accommodate the construction force, an onsite parking area was constructed, and a sewage treatment facility was provided. After construction seeded. is completed, this parking area will be graded and Existing roads on the station site are used as much as possible for construction activities. The only new roads are those within the construction area proper and a service road created for work on the river structures. A township roadway that entered commonwealth Edison Company (CECO) property was closed with cpproval of the highway commissioner of Reed Township. The abandoned by controlled roadway CECO. has no public access or use and is completely No county, state, federal, or interstate highway has been rerouted as a result of Braidwood Station construction.

The designated construction areas, access ways, and laydown areas were cleared to permit construction of the permanent station structures and facilities. In order to minimize erosion, a construction drainage development plan.

system was incorporated into the site Temporary gravel roads and permanent roads were installed with site grading and drainage facilities to permit all-weather use of the site for movement and storage of materials and equipment during construction.

Areas only temporarily disturbed by construction were stabilized by native vegetation. In all instances, erosion control measures cround the construction area were planned and scheduled as part of construction operation. To the extent possible, mechanical disturbances during the construction of any of the associated facilities were limited to the immediate construction site. In "

construction laydown areas, temporary diversions were constructed 4.1-2

Braidwood ER-OLS

() Since there are no projections or encroachments on the Kankakee River flood plain, the Kankakee River was not considered to be adversely affected by the construction of the river structures.

The following special provisions were adopted during the construction of the intake and discharge structures:

1 l a. All construction debris is immediately removed to prevent pollution of the Kankakee River.

i b. All riprap and seeding work is performed so as to j ensure optimum protection against potential soil erosion.

l

c. Construction is carefully conducted to minimize increases in suspended solids and turbidity, which j may degrade water quality and damage aquatic life

outside the immediate area of operation.

1 j

d. All dredged or excavated materials are placed in a confined area to prevent the return of polluted

materials to the watercourse by surface runof f or by

leaching.

t i e. Only clean, properly graded riprap materials are used in order to minimize local turbidity.

f. All cut and fill surfaces are well compacted, smooth, and uniform.

9 Where required, a uniform and dense stand of healthy j perennial grass, free from bare spots and gullies formed by erocion, is provided.

The water supply and navigational capabilities of the Kankakee 4,

River were not considered to be adversely affected by dredging or other site preparation and construction activities.

, Flooding of the cooling pond area will result in a reduction in j land species numbers because of the loss of diverse habitats (see Subsection 2.2.2) and the creation of specialized habitats such

, as marshes and open waters. This should result in an increase of 4

waterfowl and shore-bird species. Although the Braidwood Station site is not situated along any major flyway corridor for j migratory waterfowl, except for geese, the possibility exists that as a result of the relatively warm pond water temperatures

during winter and early spring migratory periods, waterfowl may j be attracted to the pond's ice-f ree water. Only small numbers of j geese normally would be expected to stop at intermittent water areas along their migratory route.

1 Aquatic vegetation is expected to develop in areas of pond i shoreline, island perimeter, and throughout areas of low water i depth. Plant development and growth will depend on water turbidity, water quality, and growth substrate. Vegetation may 4.1-5 1

I Braidwood ER-OLS AMENDMENT 1 g FEBRUARY 1983 w establish additional supporting factors for waterfowl feeding and nasting areas.

Aquatic mammals, reptiles, and amphibians are also expected to increase in population density as a result of the pond formation for two reasons. First, the pond should provide adequate habitat for these species, and second, the relatively warm air and water temperatures may result in increased winter activities.

The construction of the essential service water cooling pond and pond screenhouse will have no impact on the local groundwater regime since the pond and screenhouse will be built within the area scaled off from the sand aquifer by the dike.

Dswatering operations consist of pumping only from collector ditches and therefore, do not significantly af fect groundwater levels. Eight piezameter wells were installed around the Braidwood Station main building excavation and are being monitored to ensure that dewatering operations do not affect local groundwater. De-watering operations have not affected groundwater level or quality (see Subsection 6.1. 2) .

4.1.4 Monitoring Program 4.1.4.1 Terrestrial Studies CECO. conducted 2 years of preconstruction terrestrial monitoring at the Bqaidwood Station site. The first year (1972-1973) baseline terrestrial surveys began in the fall of 1972 and continued on a seasonal basis during the winter, spring, and summer of 1973. The results and projections of construction impact concluded from these 1972 through 1973 studies were included in Subsection 2.7.1 and 4.1.5 of the "Braidwood Nuclear Generating Station - Units 1&2 Environmental Report - Construction Permit Stage" (ER-CPS). The impact was assessed in this report and in the "Braidwood Final l

Environmental Statement" (FES).

To augment the 1972 through 1973 baseline survey, a program was designed for the 1974 thrcugh 1975 period. The results and conclu-sions presented in the 1974 through 1975 final terrestrial report further support the impact assessment presented in both the ER-CPS and the FES. The 1974-1975 report summaries are included in Sub-section 2. 2.5.

A comparison of the 1972 through 1973 and 1974 through 1975 ter-restrial survey results indicated no significant differences be-tceen these 2 years of baseline monitoring. Similar conclusions 4.1-6

l F Braidwood ER-OLS- AMENDMENT 1 r'} FEBRUARY 1983

! (s

$ resulted in the elimination of a construction-phase terrestrial

! monitoring program (see Appendix 4.lA).

t In order to detect the ef fects, if any, of filling the Braidwood l cooling pond, a terrestrial monitoring program was developed. This ,

j program consists of. vegetation documentation-before and after the i filling of the cooling pond. Consequently, any environmental ef-l fects c that could possibly be due to the filling of the cooling pond l would be detected by the surveys.

4.1.4.1.1 Summary of 1979 through 1982 Terrestrial Monitoring Cropland 'is the ' predominant land use in the vicinity of the Braid-wood Station. Vegetation composed of trees, shrubs and herbaceous plants occurs along roadsides and on the borders of the cropland.

For the most part, the cooling pond has utilized the area formerly used in strip mining. Vegetation around the cooling pond is char-acterized by species which invade disturbed soils. The most promi-nent is cottonwood (Populus deltoides),

i During the 1979 survey most crops were either harvested or were ready for harvesting. In the following surveys (1980, 1981, 1982) crops were in their late maturation stage.

The surveys indicate insect damage and a number of common plant diseases on the roadside vegetation. None of the diseases are i attributed to act'vities associated with the station. These dis-eases normally co-exist with the local plant species to some de-gree. The more representative of the damage and diseases during the past four years include spider mite injury, oak wilt, Dutch elm disease, powdery mildew, tent caterpillars, pine-wood nematode and canker diseases.

The crops in the surrounding area exhibited diseases such as Phyto-phythoria root rot and nutrient deficiencies. Also, some crops had water'related damage. Monitoring of observation wells in the area j confirm that the slurry cutof f trench method of seepage control l that was used for dike construction has been effective, therefore, water seepage from the cooling pond is not a suspected cause of this problem. Instead above average rainfall and poor farming techniques are more likely responsible.

Inside the site boundaries, some vegetation displayed injury re-sulting from soil compaction or physical damage. This is attri-buted~to station construction activities. Moreover, other vegeta-I tion, both on and outside the site, exhibited inury from natural occurring wood rot or storm damage. There were some isolated cases off of the site where vegetation was injured due to farming opera-tions.

None of the above diseases or injuries are considered to have been exacerbated by the filling of the cooling pond. Furthermore, none 3 of the vegetation problems occurring outside of the station boundary are considered to be a result of activities associated with Braidwood Station.

FEBRUARY 1983 4$1.4.2 Aquatic Studies J CECO. conducted 2 ' years of preconstruction aquatic monitoring at the Braidwood Station: site. The first year (1972-1973) baseline aquatic monitoring program on the Kankakee River and Horse Creek j began'in October 1972fand continued through September 1973. The

results and projections of construction impact concluded from.the

-1972: through .1973 studies 'were included in' Subsections 2.7.2. ,

5.1.3,,and 5.1.4.1 of the ER-CPS-and in-the-FES.-

1 To~ augment .the 1972 through 1973 baseline survey, a program was t

designed for the 1974 through 1975 period. Field surveys for the i 1974,through 1975 program were initiated on the Kankakee River and 4

Horse Creek injMarch 1974 and were conducted through March 1975. j 2 This completed the preconstruction monitoring program. The results' of the 1974 through 1975 program are presented in Subsection 2.2.1.

i CECO.'s construction phase aquatic monitoring program began in

~

4

-March, 1977 and included seasonal sampling of Horse Creek and the Kankakee River during the years of 1977, 1978, 1979 and 1981. '

{

Sampling was suspended in 1980 due to the cessation of station

! construction ' activities.- Biological parameters that_were monitored 1 i_ during the sampling periods, included periphyton, benthos, fish, fish eggs and larvae and water chemistry. A summary of the moni-i toring program objectives are-contained in Appendix 4.lB. Results !

j of the construction phase aquatic monitoring are found in section j 4.1.4.2.1.

i l- ' 4.1. 4. 2.1 Results of Construction Phase Aquatic Monitoring With regard to-periphyton collected from artificial sub-

j. strates, most species identified during the 4-year study were dia-

toms (Bacillariophyta) although considerable accumulations of green j algae (Chlorophyta) and blue-green algae (Cyamophyta) also oc-l curred. The most productive station based on accumuler.ed biomass ,

i was located approximately 1000 feet downstream of the discharge j structure (station SL). The least productive was located in the I i immediate vicinity of the discharge structure (station 4R). Al-though there was no apparent relationship between accumulated bio- 1

mass and ancillary factors such as light, turbidity, or current, i increased diversities were apparently associated with reduced cur-rent. Any variances in the periphyton communities was reflective

of natural habitat dif ferences.

Benthic communities in the study area exhibited comparable taxa

! numbers throughout the study. Communities at three stations (sta-tions 4R, 4L and 6L) remained essentially unchanged since the study l The' stations

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 llk (Stations 1R and 6R) shifted from a marginally depositional charac-tor to an erosional character. The dominants at these stations changed from 011gochaeta, Hexagenia and Sphaerium to Heptageniidae.

Biomass and density of Hexagenia decreased at two stations (Sta-tions SL and SR) although they retained their depositional consti-tution. Communities present in the immediate vicinity of the dis-charge structure (4R) exhibited no detrimental effects resulting from construction. Any significant differences in the benthic community were the result of natural causes usually related to substrate type or flow rate. Diversity values indicated that the communities were under little environmental stress.

Of the fish collected, no species were on the Illinois list of cndangered or threatened species, although the pallid shiner, Notropis amnis is rare in the area studied.

The numbers of fish in seine hauls declined over the study period and was probably due to increased water velocities and water depths. The electrofishing catch in August, 1981 was dominated by redhorse suckers (Moxostoma spp.) accounting for 51 percent of the total biomass which was the highest biomass collected during the 4-year study. Stations on the left side of the river were more productive than those on the right, reflecting habitat differ-ences. The effects of construction on total biomass and abundance of fishes collected at the intake site (Station 3R) were negligible 1 lll although there was a change in species composition. Most fish collected in 1981 exhibited slow growth and lower than average condition factors, possibly due to high water and turbidity levels.

Ucter quality was generally good. Phosphorus levels were high, but not unusual for Illinois waters. The trace metals of cadmium and manganese along with the pesticide dieldrin and PCB's exceeded recommended levels in August 1981. However, the presence of the intake and discharge structures had no apparent effect on water quality of the study area.

In summary, any variance in the biota of Horse Creek and the Kankakee River near the Braidwood intake and discharge structures was reflective of natural habitat or seasonal changes in the envi-ronment. There was no apparent effect on the environment from station construction activities. This conclusion was supported by the diverse assemblage of fish species which included a widespread distribution of " pollution-intolerent" species, as well as the more common tolerent species. Moreover, the water quality was good with the periphyton and benthos communities exhibiting only variations due to natural ecological conditions. Abstracts detailing the results from each of the four years during which the area was studied are included in Appendix 4.lC.

FEBRUARY 1983 4.1.4.1 Clam Bed' Mapping A reconnaissance of the pelecypod fauna of the Kankakee River near the Braidwood Station was conducted by Nalco Environmental Sciences on June 23 through 25, 1976. It was found that clam beds were located upstream and downstream of the intake and discharge area and also in the immediate area of the intake and discharge struc-tures. A total of 18 species of clams was collected during this study (see Table 4.1-1). Actinonaisas ligamentina and Lasmigona costata were the two most abundant species collected from the Kankaee River (Nalco 1976).

In response to a request ~from the United States Department of the

, Interior, Fish and Wildlife Service, a clam bed mapping program was conducted on November 2 through 4, 1976. The objectives of this sampling were to determine the configuration of clam beds in the aret, determine the species composition of the clam beds, and the densities of the clam species. The following subsections describe the materials, methods and rgsults of the November 1976 mapping program (Nalco 1977).

O i

4.1-7b

Braidwood ER-OLS 4.1.4.3.1 Materials and Methods llh A series of 24 transects was established across the Kankakee River. Twenty-one transects were established upstream and' downstream in the vicinity of the proposed intake and discharge etructures. An additional set of three transects was established cpproximately 1 mile downstream. Each transect consisted of four campling locations, one location near each shore and two midstream locations. Locations were chosen to divide the stream into approximate one-quarter sections. Once a sampling location had been established it was marked using a Hewlett Packard (Model

3810A) electronic distance measuring device. Data generated by this measuring procedure were transformed by computer program and printed out as a map. Figures 4.1-2 and 4.1-3 were based on this computer generated map. Permanent reference points have been established and any location can be re-established using this cystem.

A 0.5-square meter frame was placed on the substrate and all unionids contained by this area were collected, identified, enumerated, and returned to the river bed. Because of the deep burrowing habits of many species, the substrate section within the frame was searched to a depth of approximately 6 inches.

Collections were made either by wading or SCUBA diver.

Tcxonomic keys used included Baker (1928); Parmalee (1967);

Starrett (1971); and van der Schalie (1938). Dr. Max Matteson of the University of Illinois was also consulted for taxonomic ll verifications.

4.1.4.3.2 Results and Discussion 4.1.4.3.2.1 Species composition A total of 13 species of unionids was collected during this mapping study (see Table 4.1-2) . Historical comparisons were m:de previously (Nalco 1976) . The additional species collected during this study indicated that perhaps only two species of unionids have been lost in this section of the river during the Icst half century (see Table 4.1-3) . Three species that were previously collected only as dead shells were collected live.

Three other species were collected during the November sampling that had not been found in June 1976. One species (Pleurobema corda tum) collected in November was not reported from this area of the river by Wilson and Clark (1912) . None of the unionid l cpecies collected is considered rare or endangered (U.S.

DCpartment of the Interior 1976) .

l l 4.1. 4. 3. 2. 2 Densities of Unionid Species D nsities of the unionids collected are summarized by location in Table 4.1-4. Maximum densities generally correlated with l

~

! A mussel survey which duplicated the 1976 mapping study was con-f ducted during October- 13-16, 1981 approximately one year after completion of the intake and discharge structures.

4.1.4.4.1 Results and Discussion 4.1.4.4.1.2 Species Composition A total of 15 species of freshwater ~ mussels (nalades) and the O Asiatic clam, Corbicula fluminea were-collected during the mapping (m/ survey (See Table 4.1-5). The predominant species was Actinonaias carinata (approximately 75 percent of total mussel fauna). Amblema costata ranked a distant second while all other species collected in 1981 were minor components of the total mussel fauna.

. Three fresh-dead specimens of Plethobasus cyphyus were found in a muskrat midden during the present survey. This mussel species is 1 considered uncommon to rare in Illinois but one relic valve of this species was collected by others in a 1976-1978 survey of the Kankakee River. Although Lampsilis higginsii, a federally pro-tected mussel, was last reported in the Kankakee River in 1955, no live individuals or relic valves of this species was observed in the 1981 survey.

.The 1981 survey yielded three species, Anodonta grandis grandis, Megalonaias gigantea and Strophitus undulatus, which were not col-lected in the 1976 survey. Only one species, Lasmigona complanata was present in 1976 but not in 1981. This speciet i s found in quiet water and fine-grained substrata, a habitat not common in the study area.

FEBRUARY-1983 occured in the. riffle section of the.. study area which wastapproxi-Gately; 2-4 feet in depth with a fast current velocity (approxi-- 1 mately.3 ft/sec). .The area was a predominantly rubble and inter-stitial. sand substrate. Actinonaias carinata was the dominant species in.this riffle habitat (maximum density: 76 individuals /

l mZ) . All other1 species were generally widely scattered and never

. abundant at any location with the exception of Elliptio dilatatus.

Although this-species was present at only one site, three individ-uals (density = 12/m2) were collected from a single frame sample.

4.1.4.4.1.3 Configuration of Clam' Beds Maximum densities of freshwater mussels -occurred in the rif fle habitat near the-mouth of-Horse Creek. The configuration of this dense mussel assemblage in-1981 was similar to the configuration found in the 1976 survey._ Any density difference between the sur-veys were attributed to the natural variability.

Generally, the area sampled upstream from the riffle near Horse Creek was void of mussels or sparsely populated as was the area immediately downstream from the riffle habitat (near the area of 1 the intake structure). This configuration was comparable to that found in the 1976 survey.

The 1981 survey indicated a slightly more widespread mussel assem-blage present one mile downstream of the intake and discharge r

! structures. However, relative densities in this' area were low l during both surveys.

Other mussel species collected in the study area during 1976 and 1981 were generally present in low densities and were sporadically distributed. Most of these species were collected at locations with a constant' current and rocky substrate.

4.1.4.4.1.4 Impact of Intake and Discharge Structures Construction The 1976 and 1981 surveys indicate that the mussels adjacent to the intake and discharge structures were sporadic in distribution and low in density. Construction activities disturbed these mussels but, because of the luw density, this impact was considered insig-nificant when compared to the entire mussel community of the area.

No other impacts on the community were detected.

his report presents the results of the first year of a four-l year aquatic monitoring program that was designed' to evalute the effects .

of construction and operation of the Braidwood Generating Station on the biota and water quality of the Kankakee River and its nearby tributary Horse Creek.

The algal taxa found in the Kankakee River and Horse Creek from May through November 1977 were indicative of an alkaline environment and were generally evenly distributed in the study area. The presence of many of the same species in the Kankakee River and Horse Creek would be expected due to the cosmopolitan distribution of many algal taxa. Horse Creek and the right-side stations downstream did, however, occasionally

- exhibit different trends in composition of dominant organisms which re-flected the distinct nature of Horse Creek and its possible impact on the river. Periphyton data did not indicate any adverse effects within ,

the monitoring area due to construction.

i A total of 158 taxa of macroinvertebrates were collected from the Kankakee River. The greatest diversity occurred in stations with bedrock-type substrates which yielded over 70 taxa each. Horse Creek samples contained 76 taxa. Substrate type was the most important factor affecting distribution. S e predominant groups were Oligochaeta , Ephemeroptera, Trichoptera, Mollusca, and Chironomidae. The density of bottom organisms in the Kankakee River ranged from a low of 3158 organisms a-2 in April to 10,889 individuals a-2 in October. Horse Creek was represented by a high of 2646 individuals a-2 in April and a low of 595 individuals a-2 I in May. Diversity indices ranged between 2.00 and 4.00 indicating I

Examinations of adult and juvenile fishes indicate a diverse assemblage of species including abundant game species and generally l l

widespread distribution of " pollution-intolerant" species, as well as the more ubiquitous types. Growth, feeding habits, condition factors, and fecundity of most fish species examined from the monitoring area indcated maintainence of good'overall conditions. Abundance and biomass shifts in fish populations occurred among collection stations and seasons but indicated no detrimental effects relatable to streamside construction activities. Nstural habitat differencas were responsible for most of the dissimilarities in fish species composition observed.

Drifting fish eggs and larvae were collected weekly in 1977 be-ginning on 13 April and terminating on 30 August. A total of 43 fish eggs and 1,374 fish larvae v ve collected during the 21-week sampling period. The most abundant fish larvae captured included unidentified cyprinids, Lepomis spp. , unidentified percids, Ambloplites rupestrisa Ictalurus punctatus, and unidentified catostomids, in order of decreasing abundance. The mean density of larval fish during the sampling period was 1.1 larvae /10 m 3 of water filtered. The highest density of fish larvae was measured in Horse Creek (Station 2) when 3.29 larvae were collected per 10 m 3 of water filtered. _

Results of quarterly water sampling revealed that the concentra-tions of the various chemical parameters (forms of phosphorus and nitrogen, biochemical and chemical oxygen demand, total organic car-bon, total alkalinity, EDTA hardness, and sulfate) varied seasonally.

SUMMARY

This report presents the results of the second year of a 4-year program designed to evaluate effects of construction and operation of the Braidwood Nuclear Generating Station on the biota and water quality of the Kankakee River and Horse Creek. Data collected in May, August, and November 1978 primarily documented deviations in communities re-flective of natural changes in the environment, since little stream-related construction activity took place during the study period. While documenting the absence of stream disturbance, this year's results also provided viother year of background date for the various biological communities 'f the monitoring area.

Periphyton collected from artificial substrates in the Kankakee River Monitoring Area in 1978 yielded a diverse flora. Horse Creek stations were among the most divarse sampled and some of the taxa common in Horse Creek were of similar abundance immediately downstream from it's confluence with the Kankakee River bc.t were of different abun-dances at other stations in the study area. Stations with high densities of organisms tended to have smaller organisms while those with the greatest calculated biovolumes had lower densities. All variations in biomass, densities, biovolumes, and diversities between stations were attributable to natural causes since no construction took place in the river during periods when artificial substrates were exposed for peri-phyton colonization.

A total cf 163 macroinvertebrate taxa from the Kankakee River and 48 taxa from Horse Creek were collected by benthic grabs during 1978.

The type of substrate present at each station was the most important factor in determining the kinds of benthic crganisms that were present.

Stations 4L, 4R, and 6L were composed primarily of bedrock. Stations lL, IR, and 6R were composed primarily of silt, sand, and gravel. Horse Creek was composed primarily of sand. Stations SL and SR were composed primarily of silt and fine sand.

He greatest number of taxa was found at stations 4L, 4R, and 6L ,

with over 73 taxa at each stations the remaining stations, excluding Station 6R, had 41-55 different taxa. The seasonal relative abundance in the Kankakee River was 763,1,549, and 1,998 individuals a-2 during May, August, and November, respectively. In Horse Creek, the relative abundance was 372, 1,377, and 2,912 individuals ( 2 during May, August, and November, respectively. The seasonal biomass in the Kankakee River

' was 4,302, 2,334, and 3,977 og ( 2 during May, August, and November, respectively. In Horse Creek, the biomass was 320, 1,062, and 1,914 i og m-2 during May, August, and November, respectively.

The diversity index values generally ranged from 3.00 to 4.50, r

indicating a relatively clean river, with a variety of organisms pre-

, sent.

i i One hundred fifty-eight macroinvertebrate taxa were collected from

) artificial substrates in the Kankakee River and 108 taxa were collected

' from Horse Creek during the three exposure periods of 1978. Spring

! comunities in the Kankakee River were dominated by immature insects of the filter feeding and herbivore trophic levels. Larvae of the black .

fly, Simullum, predominated most stations. The Horse Creek comunity was dominated in spring by 011gochaeta and Chironomidae. Mayflies of j the collecting-scraping family, Heptagoniidae, accounted for one-third l

of the total summer Kankakee River abundance and were predominant at most stations during this period. Sumer comunities at the two Horse ,

f Creek stations differed in many respects, but were both dominated by herbivore-detritivores comon in lotic depositional situations. The -

4 fall communities at all Kankakee River sampling locations were pre-

i I

dominated by midges of the subfamily Orthocladiinae. Diversity values

! for the three collection periods ranged from 1.81 to 4.70. Analysis of taxonomic compositions, numbers of individuals, numbers of taxa, and diversity values of consunities colonizing artificial substrates indi-f cated that the water quality of the Kankakee River' and Horse Creek was good during the three exposure periods.

Square frame and bongo samplers were used to collect ichthyoplankton drift from 17 April to 30 August 1978. A total of 5,178 fish larvae were collected with square frame samplers while 5,883 were collected with bongo samplers. Fcr most taxonomic groups, numbers of larvae collect M per cubic meter of water sampled were greater in Horse Creek than in the Kankakee River at the N&W Railroad bridge. Group A percid larvae was the only group which had a greater absolute abundance in Horse Creek than at the railroad bridge.

A total of 53 adult and juvenile fish species were collected during 1978, bringing the total number of discrete fishes to 68 for the two years of study of the sonitoring area. Many of the cournon species are noted for their intolerance of polluted conditions and are indicative of the good water quality and diverse habitat that typifies the study site. Differences in species composition and abundance, as measured by seine, electroshocker, and hoop net, were related to habitat variations and changed between sampl,ing sites as natural conditions fluctuated. Set.ne collecting sites were consistantly deviant from others during a period when little rele-vant construction activity occurred. 7ecation 5 also harbored a different composition of fishes than other areas since it was more lake-like than riverine.

A creel survey of the lower Kankakee River was conducted during the open water season of 1978. Results indicate the majority of fishing effort was expended in those sections of the river open to public use.

Most fishermen did not fish for any particular species, though fishing effort expended on channel catfish, smallmouth bass, and walleye was high relative to other species. An estimated 1,205 fish weighing 540.8 kilograms were caught during the survey year. In decreasing order of numbers of fish caught carp, channel catfish, smallmouth bass, shorthead redhorse, freshwater drum, and rock bass were species most frequently 9

O caught. Biomass of the catch was dominated by carp, channel catfish, l

l shorthead redhorse, smallmouth bass, gciden redhorse, and freshwater drum, respectively. The mean annual catch rate for all species was 0.097

' fish and 43.204 grams of fish per manhour of effort. Fishing success declined as the survey year progressed from spring through fall. Most i fishermen still-fished from shore with natural bait and ' resided 26-50 ,

miles from the section they were fishing.

Water quality of the Kankakee River Monitoring Area was good with respect to most parameters studied in 1978. Turbidity rose downstream J

of intensive construction a ;tivities at the Braidwood intake site, but i

returned to normal levels in only a short period and remained at normal levels further downstream. Turbidity increases were small compared to k natural fluctuations that occurred at all stations due to natural causes.

Significant variation in measurements was generally by date, which in-corporates river discharge as an important factor. Differences in water

chemistry between locations generally involved differences between Horse Creek and the river rather than between stations on the Kankakee River i itself.

August, and November 1979 primarily documented oeviations in communi-ties reflective of natural habitat differences ar$ seasonal changes in the environment. No relevant stream-related constcuction took place during the study pericd, but dredging occurred before this year's sam-pling began. The 1979 sampling year, therefore, represented the first While documenting year since construction was essentially complete.

the absence of severe stream disturbance from construction, this year's results provided another year of background data for impact comparison during plant operation.

Periphyton collected from artifical substrates in the Kankakee River Monitoring Area aftei approximately 28 days of exposure yielded a g diverse algal flora. ,The abundance of the periphyton as accumulated biomass differed between stations and seasons in 1979. Th'e periphyton diversities were greatest in Horse Creek in August and November while Stations il and IR had the grer est diversities in May 1979. Some of the taxa most abundant in dorie Creek at times had similar abundance at stations downstream from its confluence witn the Kankakee River but These trends sug-lower abundance at other stations in the study area.

gested an influence of Horse Creek on the Kankakee River periphyton.

St aj ions or seasons with high densities of organisms tended to have smaller organisms while stations or seasons with the greatest calcu-lated biovolumes had lower organism densitics. No differences were observed in the periphyton comniunity in 1979 which could be attributed to construction activities that occurred in 1977 or 1978.

O 4.1C-8

Braidwood ER-OLS AMENIMENT 1 FEBRUARY 1983 A tot 31 of 163 macroinvertebrate taxa from the Kankakee River and 69 taxa from Horse Creek were collected by benthic grabs in 1979. The predominant taxa were Oligochaeta, Ephemeroptera, Trichoptera, Chirono-midae, and Mollusca, accounting for 89% and 93% of the benthic communi-ties in the Kankakee River and Horse Creek, respectively. The sub-strate composition was the most important factor determining the, diver-sity of organisms represented at each station. The greatest number of ,

taxa were found at Stations IL, 4L, and 4R, with 82-87 taxa collected; the remaining stations ranged from 66 to 77 different taxa. The aver-ace density in the Kankakee River was 2389, 1886, and 5526 individuals m-2 and the average biomass was 7023, 2552, and 6437 mg m:2 during May, August, and November, respectively. The diversity index

. values ranged from 2.58 to 4.66 indicating a relatively clean river, under little environmental stress, with a variety of organisms pre-sent.

Macroinvertebrate connunities colonizing artificial substrates were also used to aid in the assessment of water conditions in the area ,

of the Braidwood Nuclear Power Station and to provide baseline data for use in the future evaluation of plant operation. One hundred forty-six taxa were collected from the Kankakee River and 103 taxa collected from Horse Creek during the three exposure periods of 1979. Spring and sum-mer connunities were dominated by organisms at the filter feeding and scraping-gathering trophic levels. Larvae of the caddisfly Cheumato-psyche were predominant at most stations during these two seasons.

Other dominant taxa included the midge Rheotanytarsus, the caddisfly '

Hydropsyche phalerata, and the mayflies Baetis and Stenonema. Midges l I

of the subfamily Orthocladiinae (primarily Chaetocladius and Ortho-cladius) accounted for 56.5% of the total fall abundance and predomi-nated all but one station during this period. Analysis of community structure and diversity indices indicated that the water quality of the Kankakee River and Horse Cree'k was good during the three exposure periods of 1979.

The abundance and distribut ion of ichthyoplankton in the Kankakee dp River at the Braidwood Station intake site was estimated from cata 4.1C-9

- s

Breidwocd ER-OLS AMENDMENT 1 FEBRUARY 1983 gathered from two upstream sampling locations. Drift densities of 'ich-thyoplankton were highest in Horse Creek, a nearby small tributary, and l

indicated its importance as a nursery ano spawning area. Drift rates of ichthyoplankton were highest at the railroad transect in the Kanka-kee River and indicated that although densities of larvae were higher in Horse Creek, larvae were more abundant in the Kankakee River. The spatial-temporal distribution of the total larvae caught indicated that larvae were more abundant along the plant-side shoreline in the Kanka-kee River and that most larvae drifted during the dusk and night sam-pling periods. Factors regarding potential entrainment losses were assessed and indicated that ichthyoplankton comunities produced in Horse Creek may be preferentially entrained during some flow periods.

A total of 53 different fish species belonging to nine different f amilies was captured during 1979, bringing the total number of species known to occur in the monitoring area from 1977-1979 to 72 fish species and three sunfish' hybrids. Many of the common species are noted for their intolerance of silty or polluted conditions and are indicative of h the good water quality and diverse habitat which typifies the monitor-

~

ing area. Major differences in species composition and abundance, as measured by seine, electroshocker, and hoop net, were related to habi-tat variations ard changed between sarrpling sites as natural conditions fluctuated. Construction replaced the river's bank for a short dis-tance and then deepened the river directly in front of the screenhouse.

The effects of bank replacement depended on environmental conditions, alternately attracting and repelling fish from the new bank. Dredging furthcr altered the immediate habitat, averting much of the fish com-munity from that site. The displacement of fish from that small por-tion of the river was not detrimental to the fish oopulation. Fish tagging results indicated that while sedentary groups of rock bass, smallmouth bass, or other fishes might be forced to abandon the immed-iate intake area, movement occurred naturally for portions of each species and could not be considered deleterious. Fish were generally in good condition, grew well, and showed no unusual signs of stress, but should not be forced to endure extremely low water levels. g l

FEBRUARY 1983 The water quality of the Kankakee River in the Braidwood Aquatic Moni-toring Area in 1979 was good with respect to most parameters analyzed. Dif -

ferences in concentrations by date, station, and the interaction bet wen date and station were evident, but results varied according to parameter.

Dissolved oxygen was high at all times except for some periods in August.

Phosphorus levels were high, but typical for Illinois rivers. Heavy metals a

i had elevated concentrations in February.

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 O

ABSTRACT l A multidisciplinary environmental monitoring program for the Kankakee River near Wilmington, Illinois was conducted during late summer 1981 by a team of investigators from the Illinois Natural History Survey. This study was the fourth in a series, designed to evaluate construction and preoperational effects on the aquatic ecosystem from Comonwealth Edison's riverside intake and dis-charge structures for the Braidwood Nuclear Generating Station.

The scope of this study included the analyses of the aquatic com-munities of periphyton, benthic macroinvertebrates and fishes, and water chemical parameters during a single season.

Periphyton collected from artificial substrates in the Kanka-kee River and Horse Creek during the July-August 1981 exposure period after 28 days of exposure yielded a diverse algal flora which included 99 species most of which were found during July-August of previous study years. Most species identified were g

members of the Bacillariophyta (diatoms) although considerable ac-cmulations of the Chlorophyta (green algae) and Cyanophyta (blue-green algae) also occurred. The most productive station during the 4-year study was Station SL and the least productive station was Station 4R based on accumulated biomass of periphyton (ash-free weight). Several taxa were significantly less abundant by densities and/or biovolumes at Station 4R than at other stations; calculated diversities were also lower at that location on the river. Although there was no apparent relationship between ac-c aulated biomass and ancillary factor 3 such as light, turbidity, or current, increased diversities were apparently associated with i reduced current at the stations sampled. The most productive years during the study were 1977 and 1978 according to calculated biovolumes for many dominant taxa and major algal divisions; the same trends were evident based on accumulated biomass. Many taxa comon to this study have been found by other investigators in the same sampling area. Although Station 4R had significantly lower g

4.1C-12

Breidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 b diversities, biovolumes, densities, and accumulated biomass than most other stations sampled .the stressed condition was apparently i

not a result of construction activities that occurred primarily

during 1977 and 1978. Greater diversity and biomass accumulations I

at Station 4R have been observed in other study years at different times of the year (i.e., May and November).

The Kankakee River and Horse Creek were sampled during i August 1981 in order to ascertain the post-construction condition

, of benthic comunities and to add to the data base established during 1977-1979. Taxa numbers comparable to the first 3 years of the study were found, but mean densities and biomass were re-

- duced. Erosional comunities dominated by heptageniid mayflies were present at Stations 4R, 4L, and 6L. These comunities have remained essentially unchanged since the initiation of the Braid-8 wood study. The comunities of Stations IR and 6R, during August 1981, had shifted from the marginally _ depositional character they

exhibited during 1977 through 1979 to an erosional character.

Dominants at these locations changed from Oligochaeta, Hexagenia and Sphaerium to Heptageniidae. Comunities at Stations SL and SR reta.ined their depositional constitution, but' biomass and density

] decreased from previous years. Numbers and biomass of Hexagenia at these locations have- declined dramatically throughout the I

study. Comunities present at Station 4R during August 1981 ex-hibited no detrimental effects resulting from the construction and ,

. pumping activities of 1979-1981. Results of statistical analyses revealed significant differences that were the result of natural causes usually related to substrate type or flow rate. Diversity values were generally above 3.00, indicating that the benthic com-munities of the Kankakee River and Horse Creek were under little environmental stress at the time of the collecticos, i Forty-nine fish species with representatives from 10 families were collected from the Kankakee River and Horse Creek in the Braidwood Aquatic Monitoring Area in August 1981. None of these 4.1c-13

species are on the Illinois list of endangered or threatened species, although the pallid shiner, Notropis amnis, is rare in Illinois waters. More total biomass was collected in August 1981 than in any previous August collection. The electrofishing catch was dominated by redhorse suckers (Moxostoma spp.) accounting for 51.4 percent of the total biomass. Numbers of fish in seine hauls declined over previous years due probably to increased water velocities and water depth. Stations on the left side of the river were more productive than those on the right, reflecting habitat differences. The effects of construction on total biomass and abundance of fishes collected at the intake site (Station 3R) were negligible although a change in species composition was noted. No differences in abundance or biomass of fish could be related to pondfill pumping operations. Potential entrainment losses were avoided by pumping prior to the occur:ence of drifting ichthyoplankton. The presence of lentic species was enhanced by high water levels. Most fishes exhibited slow growth and lower g than average condition f actors, possibly due to high water and turbidity levels. The 1977 year class of fishes was important to the fish community in 1981.

The water quality in the Kankakee river in August 1981 was good with respect to most parameters analyzed. Turbidity and dis-solved oxygen values were high throughout the sampling period.

Phosphorus levels were high, but not unusual for Illinois waters.

Trace metal concentrations were elevated over previous August col-lections. Cadmiun and manganese exceeded standards recommended by U.S.E.P.A.(1976). The pesticides dieldrin and heptachlor epoxide and PCB's were detected in the Kankakee River. Dieldrin and PCB's exceeded recommended levels. The presence of the Braidwood Sta-tion's intake and discharge structures had no apparent effect on water quality in the Kankakee River.

Brcidwood ER-CLS AMENDMENT 1 FEBRUARY 1983 rs 4.3 RESOURCES COMMITTED The construction of the Braidwood Nuclear Generating Station -

Units 1 6 2 (Braidwood Station) involves permanent and temporary l

uses of land, water, and material resources. This section describes the resources committed during plant construction.

4.3.1 Iand Resour ~es 1

In the development of the 4454-acre site, 130 acres will be affected by actual plant building activities including 35 acres j

of woods and 70 acres of cultivated fields that will be changed permanently from current land use. There are also 25 acres of I fallow fields within the plant construction area. After building construction is completed, 20 acres will be occupied by permanent physical structures.

I The pond will cover 3540 acres and will affect ,318 acres of cultivated land, 204 acres of f allow-field vegetation, 117 acres of woods, and 2838 acres of strip-mine spoil (Edmonds 197 4) .

Approximately 784 acres of the site will not be affected by site i construction. The expected impact of site construction is described in Section 4.1.

The construction of permanent f acilities on the site eliminates some wildlife habitat, which results in shifts of wildlife populations to other areas. Those portions of the site not

() occupied by the permanent f acilities or landscaped for aesthetic purposes will be allowed to return to a natural state.

The re are some unavoidable animal deaths due to construction activities (e.g., the coverage of nests and dens), particularly in the cooling pond area. During pond filling, small mamFals living on the pond site and not able to relocate to a saf e area i will be lost. Once the filling is completed, however, the pond I will provide habitat for both nesting and migrating waterfowl.

i l

Tr.e land that will be traversed by the transmission lines for the j Braidwood Station is mainly f armland. Except for areas occupied by the tower foundations, there will be no commitment of farmland resources during the proposed period of transmission line use.

i Any farmland disturbed by construction activities will be 3

restored.

4.3.2 Water Resources j

No permanent ef fect on water resources is expected at the Braidwood Station. The construction of the river intake and discharge structures will permanently alter approximately 250 1 feet of shoreline on the southern bank of the Kankakee River. No l a other permanent aquatic disruptions are expected during the construction of the Braidwood Station.

J O

4.3-1 .

Croidwood ER-OLS l 4.3.3 Materials Used The materials used for the Braidwood Station are of two types:

O those used for the construction of buildings; and fuel.

Construction materials include structural and reinforcing steel, portland cement, electrical cables, paints, coverings, and fixtures. Although these will be permanently committed during the lifetime of the plant, some of them can be at least partially reclaimed if the plant is eventually dismantled. The highly contaminated items will not be reusable. The discussion of fuel

consumption and of other resources committed during plant operation is included in Section 5.7. The decommissioning and dismantling of the plant is desc.ribed in Section 5.8.

'"T Braidwood ER-OLS AMENDMENT 1 V FEBRUARY 1983 The ext'ernal submersion dose to,small' aquatic plants and animals-is substantially.all due to the beta component of tritium.

5.2.3.3 Dose Effects on Biota Under field conditions, it cannot be shown that organisms are in any way affected by dose rates lower than 1000 millirads per day (Auerbach et al. 1971).- For example, low dose rates seem to have no effect on such commonlyused end points as survivorship, fecund-ity, growth, development, or susceptibility ~to infection. It should be noted that when considering the effects of radiation on biota other than persons, populations are of more concern than individuals. Since the dose estimates presented in this report are conservative, it is unlikely that any animal population in the Braidwood Station site vicinity will receive annual doses approach-ing_the computed levels.

5.2.4 Dose Rate Estimates for Man- !

The calculation of radiation doses to persons from radioactive effluents was performed according to "Models and Computer Codes for Evaluating Environmental Radiation Doses" (Soldat et al. 1974).

{ } Examples of dose calculation models may be found in Appendix 5.2A.

5.2.4.1 Liquid Pathways Expected annual releases of radionuclides are given in Table 3.5-3. Activity concentrations in the discharge canal were calcu-lated assuming an annual cooling pond blowdown flow of 43.2 cfs :

with 2 unit operation. Dilution of radionuclides in the Kankakee i River was not taken into account.

Estim'ated annual average doses to individuals exposed to radioac-tive liquid effluents from the Braidwood Station were calculated for pathways of fish consumption, drinking water, and recreational -

-exposure. -

Recreational use of the Kankakee River in the vicinity of Braidwood !

Station is discussed in Subsection 2.1.2.3. The estimates of ;

whole-body doses and critical-organ doses made for swimming, boat-ing, and shoreline activities are shown in Table 5.2-7.

An estimate of the expected dose rate to the whole body and criti-cal organs received from drinking water obtained from the discharge canal is shown in Table 5.2-7 even though the canal is not a drink-ing water source. Presently there is no public drinking water supply within 50 miles downstream from the Braidwood Station.

Kaiser Agricultural Chemicals has deactivated its its water purifi- 1

{}cationsystemandnowusesgroundwaterfordrinkingwatersupply. ;

5.2-7 f

Braidwood ER-OLS As noted previously, the Kankakee River in the vicinity of the Craidwood Station supports an active sport fishery. Estimates of doses received to whole body and critical organs from the consumption of fish are given in Table 5.2-7. Actual doses will be lower because of the conservative nature of the bioaccumulation factors and because the probability of a fish ctaying in one location is extremely small.

5.2.4.2 Gaseous Pathways

. Expected annual releases of radioactive noble gases and particulates from the Braidwood Station are shown in Table 3.5-6, end estimated offsite doses to individuals from these effluents cre given in Table 5.2-4. Doses were calculated using the methodology of NRC Regulatory Guide 1.109 (1977b).

Calculational models are discussed in Appendix 5.2A. Plume immersion , exposure to contaminated surfaces, inhalation, and ingestion pathways were all considered. Consumption factors for the ingestion pathways are given in Table 5.2-8 (Fletcher and Dotson 1971; NRC 1977b). An 8-month grazing period was assumed for milk animals, and a 10-month grazing period was assumed for meat animals.

5.2.4.3 Direct Radiation from Facility The annual average external dose rates due to direct radiation exposure were estimated assuming normal station operation.

llh Estimated dose rates in the vicinity of the station are given in Table 5.2-9. The sources considered were the nitrogen-16 in the primary coolant and the radioactive contents of the storage tanks holding refueling water, primary water, and secondary water. All other major and potential contained sources are below grade level or surrounded by protective shields' and can be considered to contribute a negligible amount to the total dose rate.

Standard techniques of geometric and material attenuation were used in the calculations. Credit was taken for the concrete in the containment walls and the air between the source and dose point, but no credit was taken for partial occupancy or f or local shielding provided by buildings and dwellings (etc.) and by steel tank walls and liners.

The population exposure through this pathway, direct radiation from the station, was estimated DT4od on the projected population within 50 miles of the Braidwem itation in the year 2000. This calculation yielded a negliqa *H e annual population exposure of 0.018 man-rem / year for Bn;.+ac~ Station Unit 1.

5.2.4.4 Annual Populat h Doses The population dose due to gaseous effluents to all individuals living within a 50-mile radius of the Braidwood Station was j calculated using population data projected to the year 2000. The 5.2-8

l Braidwood ER-OLS O

estima ted dose from gaseous effluents for the year 2000 population within a.50-mile radius of the site appears in Table 5.2-10. This table shows whole-body, skin, and thyroid doses l

resulting from exposure from immersion, inhalation, and ground deposition.

The population dose caused by direct radiation to all individuals' living within a .50-mile radius of the Braidwood Station was also l calculated using population data projected for the year 2000; it j is given in Table 5.2-11.

The population dose resulting from natural background radiation to all individuals living within a 50-mile radius of the Braidwood Station is given in Table 5.2-11. This dose was calculated assuming a dose to individuals of 135 mrem /yr and was based on population data projected for the year 2000.

5.2.5 Summary of Annual Radiation Doses The estimated radiation doses to the regional population from all station-related sources are summarized in Table 5. 2-11.

, - 5.6.1 Introduction

- This section. describes the actual and predicted noise effects of 1

- the Braidwood Nuclear Generating Station -- Units 1 & 2 (Braidwood 4 Station) during plant operation. All other effects of operation are discussed in other sections sections of Chapter 5.

l' 5.6.2 Approach Noise due to the operation of Braidwood Station was predicted at

four locations identified in Figure 5.6-1 as Points 1 through 4.

Points 1, 2, and 3 were selected because plant operation noise will i

] be relative maximums for offsite residential areas and because these locations are the same as ambient measurement points A, B, and C, shown in Figure 2.7-1. Point 4 was selected to assess-maxi-mum of fsite noise due to the operation of the screen house. Actual 1 noise measurements were taken at Point 4 in 1981 shortly after the 1 screen house had become operational.

The noise sources (equipment) considered in predicting continuous

()

' plant operation noise were the main power transformers, system auxiliary transformers, unit auxiliary transformers, screen-house l

transformers, auxiliary building ventilation supply and exhuast

! fans, and screen-house ventilation supply fans. Experience shows 1

that these are the major sources of continuous exterior noise for this type of station. Intermittent noise due to the operation of L unsilenced main-steam power-operated relief valves was also pre-i dicted.

! 5.6.3 Procedures 1

i Maximum expected noise level data for the major exterior sources i

identified in Subsection 5.6.2 were established based on published prediction' schemes and manufacturers' information. Noise data for transformers was obtained-from the manufacturer and from the National Electrical Manufacturers Association's Standards for Transformers, TRl-1972, Section 0.06 (1972). Ventilation-fan noise

level predictions were based on a prediction technique by J. B.

. station design requirements. Power-operated relief valve noise was predicted using a technique developed by Riley-Beaird (no date).

The noise levels for each source were extrapolated to the various prediction points, using standard prediction techniques that ac-count ~for wave divergence and excess attenuation due to atmospheric absorption, directivity, shielding, and ground effects. The fol-()

lowing values were used to account for attenuation due to atmos- 3 pheric. absorption: j i

Credit was taken for the directivity of the supply and exhuast fans based on information supplied by Koppers Company, Inc. (1963),

" Directivity Index," Drawing D-98033. Credit for directivity of 1 the mechanical draft cooling towers was not taken separately since sound level predictions were based on the vendor's proposal data, which include the ef fects of directivity. ggg Shielding or barrier attenuation was accounted for where applicable and was based on the work of Z. Maekawa (1968), " Noise Reduction by Screens," Applied Acoustics, Vol. 1, pp. 157-173.

Because .of the variability of ground conditions from season to season, attenuation due to ground effects was considered neglib-ible, and therefore, was not taken into effect in estimating excess noise attenuation.

The resulting octave-band sound pressurt levels from each continu-aus source were then combined to give the resultant overall plant operation noise level at each location. Table 5.6-1 summarizes the predicted levels. Table 5.6-2 summarizes the predicted A-weighted noise levels at each prediction point resulting from relief valve operation.

Actual field measurements at Point 4 were taken in 1981. The noise levels during normal screen house operation can be found in Table 5.6-1.

Since the predicted points are located near existing residences, station noise at these points is regulated by Rule 203 (Sound Emitted to Class-A Land During Nighttime Hours.) The com-parisons of predicted levels with Rule 203, as shown in Figures 5.6-2 through 5.6-5, indicated that the calculated station opera-tion noise levels.at all prediction points meet the Illinois regu-lations.

5.6.4.2 U.S. Environmental Protection Agency A second method used to assess the possible effects of normal oper-ation of Braidwood Station was to determine how the predicted plant operation noise levels compared with the levels of environmental noise identified by the U.S. Environmental Protection Agency (U.S.

EPA) as requisite to protect public health with an adequate margin of safety.

This comparison, summarized in Table 5.6-3, shows that the pre-dicted level at each point meets the requisite level, Ldn 1 55 dB, applicable to outdoor levels in residential areas.

.(w 5.6.4.3 DEPARTMENT OF HOUSING AND URBAN DEVELOPMENT A comparison of predicted noise due to normal plant operation with the Department of Housing and Urbas Development (HUD) critiera described in Subsection 2.7.3.3 (Ldn 65 dBA) is shown in Table 5.6-4. This comparison shows that predicted levels at all loca- $

tions meet the HUD criteria.

5.6.4.4 Preoperational Ambient Levels To permit comparison of predicted plant operation noise with preop-erational abmient noise at the plant site, levels measured at points A, B, and C (see Subsection 5.6.2) are shown in Tables 5.6-3 and 5.6-4. These tables indicate that although levels at points near the Braidwood Station property line will be increased due to station operation, the predicted levels are below all applicable regulations and guidelines. Ambient noise levels measured in the nearest communities (see Subsection 2.7.1), however, are not ex-pected to be signficantly affected by plant operation.

5.6.5 Conclusion The predicted station operatior, noise levels at property line points near existing residences meet state of Illinois regulations and federal guidelines for noise emitted to residential receivers.

() The actual station operation noise levels are expected to be lower 5.6-3

O than those presented in this Environmental Report because all pre-dictions were based on the maximum expected equipment noise. The noise impact due to normal operation of the Braidwood Station is

, therefore expected to be small. ,

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 5.8 DECOMMISSIONING AND DISMANTLING The Braidwood Nuclear Generating Station - Units 1 & 2 (Braidwood Station) is designed for an operating life of at least 40 years.

Decommissioning of this facility, therefore, is not expected to occur before the year 2025 and probably will not c; cur until much later. It is anticipated that a signficant body rf technology related to the decommissionin] of nuclear power stations will have been developed before these reactors are decommissioned. Indeed, the decommissioning of nuclear reactor facilities is already a relatively well developed technology (Smith et al, 1978). The Commonwealth Edison Company (CECO) has not yet developed detailed plans for the decommissioning of the Braidwood reactors in order to retain maximum flexibility to apply future technology when needed.

- Decommissioning is de fined, for a nuclear facility, as the measures taken at the end of the facility's operating life to assure the continued protection of the public from any residual radioactivity or other potential hazards present in the facility. Three basic approaches to decommissioning have been considered:

a. Immediate Dismantlement - Radioactive

/ materials are removed and the station is disassembled and decontaminated during the 4-year period following final cessation of 1 power production operations. Upon comple-tion, the property is released for unre-stricted used.

b. Safe Storage with Deferred Dismantlement -

. Radioactive materials and contaminated areas are secured and structures and

, equipment are maintained as necessary to assure the protection of the public from

! the residual radioactivity. During the period of Safe Storage, the facility re-mains limited to nuclear uses. Dismantle-ment is deferred until the radioactivity within the station has decayed to lower levels. Upon completion of dismantlement, the property is released for unrestricted use.

c. Entombment - Another alternative to imme- '

diate dismantlement is entombment--the ,

encasement of all radioactive meterials remaining at the site of the power plant,

{} in concrete or other structural material 5.8-1 L

. _ _ . - __ _ m, _ . _ . - . , _ _ _ . - _-.-.--__ __ _ _ _

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 19'3 that is sufficiently strong and structur-ally long-lived to ensure retention of the radioactivity until it has decayed to

' levels that permit unco.7ditional release of the site.

Deferred dismantlement, as used here, is a generic term that in-cludes whatever actions are required at some future time to accom-plish termination of the facility's nuclear license and the release of the property for unrestricted use. These actions can range from radiation surveys that show that the residual radioactivity has decayed to releasable levels to disassembly and removal of radioac-tive material.

A broad span of methods is possible under Safe Storage. These methods range from minimal removal and fixation of residual radio-activity, with maintenance and surveillance using either custodial (layaway) or passive (mothballing) protection systems, to extensive cleanup and decontamination with hardened (temporary entombment) passive protection of highly radioactive areas using limited sur-veillance and continuing maintenance programs. Each method encom-passed within Safe Storage requires some level of continuing care during the holding period, which may vary in length from a few years to about a hundred years. Each method ends with the deferred 1 dismantlement of the facility and the termination of the license for radioactive materials, thus permitting the unrestricted use of the property.

The entombment scenario considered is limited to entombment of the lower portion of the containment building, either with the reactor vessel internals removal or with the internals remaining in-place.

The rest of the plant is dismantled and relased for unrestricted use. The entombment structure is used as a repository for most of the contaminated material removed during the dismantlement of the balance of the plant. The operations required for entombment in-clude, basically, chemical decontamination where necessary, and storage, in the containment building below the operating floor level, of as much as possible of the contaminated equipment and material located elsewere in the power plant. A continuous slab of concrete is then poured above the operating floor level in the montainment building, and all wall penetrations below the floor level are sealed.

The definitions and descriptions of these specific alternatives can &

be found in Smith et al. (1978) and in its August 1979 AddenJum W (Smith and Polentz 1979). It is anticipated that future decommis -

sioning technology will retain these procedures and that various 5.8-2

I i

l Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 plant systems and components will utilize different methods of decontamination for economic reasons.

The' cost estimates for these three primary decommissioning alterna- i tives are shown in Table 5.8-1. These cost estimates have been derived from information available in Smith et al. (1978) and other documents. Unlike the estimates made in Smith et. al. (1978), a cost for deferred dismantlement and deferred demolition in the entombment cost estimate has been included.

where:

p TN = total number of trap nights, C = number of captures, and I- = trap night index.

Species identification, vigor, sex, and weight estimates were recorded, and relative densities were calculated. Surveys for mammals not included in the other studies were conducted during walking surveys of the three new .Tansect areas (A, B, and C) .

Identifications were made from actual observation of a species or from tracks, scats, dens, and other signs. The relative abundance of each was estimated.

Birds were observed seasonally during walking surveys of transects in the three study areas, with special attention given to species present during spring and fall migration periods.

Identifications were made by observing individuals and recognizing calls. Relative abundance, habitat adequacy for waterfowl, and seasonal fluctuations were estimated for

! individual species.

Belative use of the new areas was compared with the use of the O areas already studied, and the new food chain relationships were incorporated into the generalized food web established for the Braidwood Station site.

6.1.4.3.2.2.3 Marsh-Pond Study Areas concentrated herpetofauna studies were carried out on marsh-pond sections of Areas 2,.3, 6, and 9. A variety of methods were used to survey and census herpetofauna. On all trips through study areas, the species observed were recorded.

In order to quantify results for certain species (particularly lizards) , surveys were made on each study site during the June through September trips in 1974. The type and number of each species seen were recorded together with the distance walked (as measured by pedometer) on each study site.

Traps of various types were also used to quantify results. Can traps, large juice cans buried in the ground beneath a rock with the opening at surface level, were buried on four study sites for i lizards and insects. Can traps were buried on Areas 3 and 9 in i

June 1974 and on Areas 2 and 6 in July 1974. Baited hoop traps and trammel nets were set in study lakes and ponds for aquatic turtles.

Collected specimens were routinely weighed and measured. Small species were weighed on a triple beam balance, and larger species l

i were weighed by means of a spring scale that weighed to the nearest 0.5 kilogram. The length of species other than turtles 6.1-43 ;

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 lll was measured from snout to vent with vernier calipers for turtles, length was expressed as the length of carapace and/ar length of the plastron.

Several turtles were radio tagged and located during several survey periods. Birds within sight of marsh-pond areas were observed and recorded, and comparative presence of waterfowl and habitat use by waterfowl were noted. Identifications were made through direct observation and animal calls.

Insect abundance and availability as a food source for reptiles, fish, and birds were assassed in the marsh-pond areas nearer the Braidwood Station during summer surveys, using insect nets, light traps, and can traps.

6.1.4.3.3 Methods for 1979 through 1982 Terrestrial Monitoring Pyagram This program involves the analysis of low and high level false color infrared aerial photographs (Cibachrome prints). The aerial photographs cover about 13 square miles in and around Braidwood site which is sufficient to document land usage modifications re-sulting from construction activities. ggg The photographs are examined for dead or dying foliage caused by injury or disease which is distinguishable from normal foliage on the basis of signature differences in the photographs. Also, soil conditions which adversely affect vegetation are also discernible.

Once the photographs are analyzed a field examination is made of suspected vegetation by a plant pathologist.

1 l The 1979 and 1980 surveys were performed before the filling of the Braidwood cooling pond. The 1981 and 1982 surveys were performed after pond filling. The study concentrated on the area in and around the cooling pond to determine effects, if any, caused by lake fill.

The dates pertaini.ig to the taking of the aerial photographs and the subsequent field examinations are listed below:

FEBRUARY 1983 6.1.5' Radiological Monitoring The preoperational radiological monitoring program planned for the Braidwood Station was: described in the. Environmental. Report - Co'n-struction Permit Stage (ER-CPS). The monitoring program currently planned incorporates some changes in sample coll'ection and analysis that were made-to obtain more useful data. .The area to be moni-tored is essentially the same as that described in the ER-CPS (see

-ER-CPS Subsection 6.1.5).

program at least 18 months before fuel loading date. . The.preopera-tional monitoring program will provide measurements of natural 1 background and other radiation sources, such as fallout, that are external to Braidwood Station. This program will continue until <

the. plant loads nuclear fuel and-the operational-phase monitoring program begins. Details of the proposed monitoring program are discussed in this subsection.

selected on the basis of population and site meteorological condi-tions. Environmental samples will be collected at these locations with the frequencies specified'in the technical specifications.

Data Analysis. Analytical Sensitivity. and Data O 6.1.5.2 Presentation The environmental samples will be analyzed by radiochemical methods similar to the procedures of the U.S. Energy Research and Development Administration Health and Safety Laboratory (Harley 1972) a nd the U. S. Public Health Service (1967) . Ercept where otherwise noted, a germanium-lithium (GeLi) system will be used to make all gamma spectral analyses. These methods achieve the analytical sensitivities listed in Table 6.1-11.

For most sample media, variations in radioactivity levels or concentrations from month to month or from year to year are not expected to be caused solely by random processes. That is, they will not be describable by a normal distribution function.

Accordingly, for these long-term values it would not be useful to calculate the standard deviation in the routine manner. Gross teta measurement of air samples, for example, are affected primarily by the degree of weapons testing undertaken during, or just before, the sampling period, and by stratospheric radioactivity from past weapons tests. Increases may be due to recent tests, therefore, and analysis of 1 year's data for a standard deviation may produce an estimate of the variation that is not representative of any other year.

Mean values and standard deviations are, however, appropriate for any set of samples taken at the same locations over identical O time periods. For this reason, each single set of analyses will te reported as a mean with a

2 standard error.

Analytical procedures specific to the samples collected are described in the following subsections.

6.1.5.2.1 Air Samples The gross beta content of particles filtered from a measured volume of air will be determined weekly by " low level" counting of the filters. When a gamma scan is required by the specifica-tions, the filters will be composited for analyses on a GeLi detector eyetem.

Charcoal cartridges exposed for 2-week periods at air sampling !

I stations will be analyzed for I-131. An I-131 measurement on these samples will usually be made by gamma counting with a sodium iodide (t hallium-activated) crystal and a single-channel pulse height spectrometer.

For data presentation, the weekly gross beta results will be averaged quarterly for each monitoring station. The gamma spectra observed on quarterly composites of air samples will be examined for specific radionuclides. It is expected that the radionuclide composition will vary from year to year if atmospheric testing of nuclear weapons continues.

O 6.1-45

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 6.1.5.2.2 Water Samples

~

Gross beta or gamma spectral analyses of surface, well, or precipi-tation water samples will be performed by evaporating a measured aliquot of the sample, digesting, and planchetting of the processed sample, and subjecting it to a radiometric assay. Tritium analysis will be performed on water samples to a sensitivity of 200 pCi/

liter by isotopic enrichment and liquid scintillation counting.

Strontium-89 and -90 analyses will be performed on the samples by standard radiochemical procedures followed by low-level beta count-ing of total radiostrontium plus yttrium-90. Sr-89 will then be determined by taking the difference between total strontium (repre-sented by the Sr-89 plus Sr-90 analysis) and Sr-90, computed from the Y-90 analysis.

6.1.5.2.3 Sediment After being dried in an oven, sediment samples will be analyzed by gamma spectral analysis. Much smaller portions will be analyzed for their gross beta content.

6.1.5.2.4 Fish Fish and other samples of aquatic life will be analyzed for gross beta, Sr-89, Sr-90, and gamma-emitting radionuclide content accord-ing to the procedures used by the U.S. Public Health Service (1967 or Harley (1972).

6.1.5.2.5 Milk During the time cows are in pasture, May through October, samples l1 of fresh milk will be analyzed for radiciodine (as I-131) immedi-ately upon receipt of the samples in the laboratory. This method provides a sensitivity of 0.5 pCi/ liter with an overall error of analysis of 1 25%. During the rest of the year, I-131 will be determined by gamma spectal analysis. Other gammaemitting radio-nuclides will be determined by gamma spectral analysis.

Strontium-89 and-90 analyses will be made with standard radiochemi-cal techniques followed by beta counting.

The principal natural radionuclide in milk is potassium-40.

Braidwood Eh-OLS AMENDMENT l' FEBRUARY 1983 CHAPTER 8.0 - ECONOMIC AND SOCIAL EFFECTS OF STATION OPERATION The Braidwood Nuclear Generating Station - Units 1 & 2 (Braidwood Station) will create a total of 553 permanent new jobs at the sta-tion site and an estimated annual payroll of $14.6 million (in 1982 1 dollars) when the station goes commercial in 1986.

The total cultivated agricultural land to be affected by the con-struction and operation of the Braidwood Station is 270 acres. The construction of the cooling pond required the diversion of 381 acres of cultivated agricultural land. About 90% of the remaining area required for pond construction, or 2838 acres, consisted of strip-mine spoil. The total affected cultivated acreage (651 acres) is less than 0.1% of the total agricultural land in the three-county agricultural region formed by Grundy, Kankakee, and Will Counties (see Section 4.1).

Permanent new residents attracted as a result of the Braidwood Station project will be dispersed throughout the surrounding com-munities (see Section 8.4), so that there will be little effect on 7s local services. The increased tax revenue attributable to the

(_) Braidwood Station project from property taxes is estimated to be

$9.3 million in 1986 (see Section 8.2). Local taxing districts i should receive more tax dollars than required to provide the addi-tional services for the new residents.

It is not possible to determine the benefit to the local economy from the purchase of local goods and services for operation of the station. The average 1983 budget for contract payments for Common-wealth Edison's three operating nuclear stations, each with two operable units, is $17.3 million. These costs include refueling, 1 maintenance and waste disposal. The procurement of materials and services is based on a competetive bid system, and therefore no estimate can be made as to which suppliers will provide the mate-rials and service, the corresponding monetary value, or the county in which the supplier is located.

There are no historical sites located on the Braidwood site.

() Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 8.1 VALUE OF DELIVERED PRODUCTS Because the generating capacity of the Braidwood Station will be made available throughout the entire Commonwealth Edison Company (CECO) power grid, no attempt has been made to confine the use characteristics within an imaginary radius of the site. The sta-tion's electrical output has been estimated for the composition of the entire CECO service territory.

Estimates of the total generating costs for the first year of com-mercial operation for each unit are $607 million (103 mills per kilowatthour) for Unit 1 and $455 million (77 mills per kilowatt-hour) for Unit 2 (see Tables 8.1-1 and 8.1-2) .

At a lifetime average capacity factor of 65%, the plant will pro-duce 12.75 billion kilowatthours of electricity annually with as-sociated annual revenues of $836 million under the present rate 1 schedules (see Tables 8.1-3 and 8.1-4), assuming that revenue con-tributions for classes of service for the year ending June 30, 1982, remain . constant through the life of the plant. The estimated values of various benefits from the Braidwood Station project are "

listed on Table 8.1-5. Dollar values listed in this table repre-O sent revenues for a 30-year period and indirect benefits for a 30-year period present valued to January 1, 1983 at an effective interest rate of 13% per year.

I[ ) Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 8.3 OPERATIONAL PHASE EMPLOYMENT During the estimated 40-year lifetime of the Braidwood Station, gains in local employment will be effected through the creation of 553 new Braidwood Station operating staff jobs. These 553 plant employees will earn a total of $14.6 million ennually in 1982 dol-4,

.lars (see Table 8.3-1). This value is based on 1982 CECO. generat-ing station payroll data.

The average income of $26,318 in 1982 for a Braidwood Station oper-

ating staf f employee can be compared to the projected average in-come of workers in the local area around Braidwood Station (local area defined as the communities of Braidwood, Gardner, Wilmington, Godley, South Wilmington, and Coal City; see Section 9.4). Table 8.3-2 shows a 1982 projected average wage of $23,846 for local residents based upon 1970 census tract information and the Consumer Price Index for a period extending Trom 1970 to 1982. The Braid- 1 wood Station average wage, however, represents a select group of employees, whereas the local earning figures represent all wage earners, including part-time and fixed income earners.

(N

\_)

The induced new employment in the east-northeastern Illinois region is estimated to be 498 new jobs based on a local multiplier of 0.90. The local multiplier is defined as the number of service occupation employees in 1974 divided by the number of production occupation employees in the same year. It was calculated using data obtained from the Illinois Department of Business and Economic Development (1976). The total employmeric generated in the east-northeastern Illinois region, which includes Braidwood Station, is therefore estimated to be the direct employment plus the induced employment, or 1,051 new jobs.
