'85 JUN 13 A11 :47 NRC Docket Nos. 50-456/457 0FFICE OF SECHuAr -
00CKETING & SERVIM
Dear Mr. Denton:
BRANCH Enclosed is Amendment 7 to the Braidwood Station Environmental Report - Operating License Stage.' This Amendment consists of voluntary revisions to update and correct the report. The revisions cover material contained in the following chapters:
Chapter 3 The Station Chapter 6 Effluent and Environmental Measurements and Monitoring Programs Amendment 2 QE100.1 Section 3.9 Transmission Facilities, Subsection 3.9.1 Location of and Description of Richt-of-Way and QE100.1 have been revised to clarify what aspects of the transmission rights-of-way (ROW) are timely for review in accordance with provisions of the National Environmental Policy Act.
This Amendment removes details of future uses of portions of ROW's that are not needed for construction of transmission lines to transmit power from l
Braidwood Station Units 1 and 2.
These ROW portions were originally included in the Environmental Report because at the Construction Permit l
stage we considered that additional units in the Braidwood vicinity would be needed to meet our load growth within seven years after Braidwood Units 1 and 2 came into service. We determined that the output of those units could be delivered to our system most efficiently by a 765 kV transmission line, and we acquired the subject ROW portions for that purpose.
Since that time the situation has changed.
Substantial decline in our load growth has led to deferral of our planned capacity additions, and we do not now plan to
~
construct additional units at Braidwood for at least 25 years.
We, l
therefore, do not plan to construct a 765 kV line associated with Braidwood l
Station until at least that time.
The existing land uses have been identified and archeological surveys made for all ROW's associated with the Braidwood transmission lines including additional properties obtained for future use.
It is not timely j
' to conjecture what the ultimate use of this property may be since it is not required for Braidwood Station Units 1 and 2, the licensing of which is the Federal Action under consideration.
chapter 6:
Effluent and Environmental Measurements and Monitorina Proarams:
Subsection 6.145.1 Samplina Media, Locations. and Frecuency (Radiological Monitoring) has been revised so that air sampling locations depicted on Figure 6.1-7 correspond more closely with their locations as indicated in Table 6.1-10.
Three (3) originals and forty-one (41) copies of this letter together with forty-one (41) copies of Amendment 7 are being provided for your use. In accordance with 10 CFR 51.40(b), an additional one hundred nine (109) copies of this Amendment are being held for direct distribution to Federal, State and local officials, as appropriate.
Please address any questions that you or your staff may have regarding this matter to this office.

AMENDMENT 7 JUNE 1985 t
3.9 TRANSMISSION FACILITIES 3.9.1 LOCATION AND DESCRIPTION OF RIGHT-OF-WAY Figure 3.9-1 shows the transmission connections f or the Braidwood l
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 kV line constructed-on new right-of-way (ROW) to an existing line on the property of the Crete Transmission Substation.
One circuit of the double circuilt 345 kV line will connect to the Bloom Trans-mission Substation with an intermediate connection at the Davis 4
Creek Substation.
The other circuit will connect to the Burnham Transmission Substation.
No connection will be made to the Crete 7
i Transmission Substation.
There are no plans at this time to con-struct any additional transmission line originating f rom the Braidwood Station in conjunction with Units 1 and 2.
Figure 3.9-2 shows the detailed route of the new line from the Braidwood Nuclear Generating Station - Units 1 and 2 (Braidwood i
Station) to the existing Crete Transmission Substation.
This route i
traverses approximately 55 miles and crosses nearly flat agricul-tural land of low relief.
i The basic ROW requirement f or the double circuit 345 kV line which will transmit the power from Braidwood Station is 145 feet wide.
The following ROW descriptions are included so that land use can be evaluated for all property acquired, including archeological sur-veys.
A 330 foot ROW that includes space for a double circuit 345 1
kV line and a future line comprises the first 7.3 miles.
The next 15.6 miles is, in general, also 330 feet wide and accommodates a 7
four circuit 345/138 kV transmission line and, for the most part, has space for a future line.
In Section 36 of Rockville Township in Kankakee County, the four-circuit construction terminates at the Davis Cr'esk 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 line.
The next 17 miles between Wilton and Washington Townships involves a 180-foot widening of an existing 200-foot ROW.
This 380-foot ROW will have a double circuit 345 kV line parallel to and with structures opposite those of an existing j
765 kV line.
From Washington Township 7.75 miles northward to the Crete Substation, a new 235-foot ROW will accommodate a double cir-cuit 345 kV line and a future four circuit 138/345 kV line (see Figure 3.9-2).
Structure types for the 55 mile transmission line i
will be similar throughout, single shaf t structures for tangent and light angles (up to 130) and lattice steel towers for angles over 130 The single shaft structures will normally not exceed 6 feet

Braidwood ER-OLS AMENDMENT 1 FEBRUARY 1983 AMENDMENT 7 O
JUNE 1985 3.9.4 RADI ATED ELECTRICAL AND ACOUSTICAL NOISE 4
The diameter of the conductors used will be in the range that re-sults in low corona, audible noise, and electric noise.
The same 7
engineering criteria used on past designs, resulting in few prob-lens, has been duplicated or improved for this transmission line.
3.9.5 INDUCED OR CONDUCTED GROUND CURRENTS Induced or conducted ground currents can become a significant fac-tor in urban areas where extensive networks of pipes and cables i
have been placed underground.
The magnitudes of currents induced j
into such underground networks are dependent upon the current in
~
the overhead transmission lines, the distance above the ground, the soil characteristics, and the extent of parallelism between the transmission lines and the underground equipment.
Also, during high ground f ault conditions, present designs are such that the entire fault current does not pass through the ground.
High speed relays at the substations operate to render such situations highly transient, reducing the potential corrosion due to the " battery effect".
(The soil can serve as as an electrolyte between the transmission ground and the underground equipment of other sys-tems.
As with conventional batteries, corrosion of these "ter-O minals" could result.)
A complete analysis of these problems can-not be made until the load currents have been determined and load flow studies have been completed.
3.9.6 ELECTROSTATIC FIELD EFFECTS l
Electrostatic fields are present at any voltage level.
The field strength is dependent upon voltage, height of conduct, and distance f rom the centerline of the support structure.
Past installations of 138 kV and 345 kV lines have produced f ew if any complaints.
Introduction of 765 kV lines, however, has caused review of these effects and explanations to the public of the electrostatic fields under these lines.
The intensity of the field can be calculated before installation and actually checked by measurement af ter in-stallation.
Past experience has shown calculated values to have been conservative.
Based on these conservative calculated values, the 345 kV lines, oither independently or in conjunction with 138 kV lines, are not expected to cause significant electrostatic ef-fects.
Where the 345 kV lines are to be placed parallel to the existing 765 kV line, Section J-K as depicted on Figure 3.9-2, cal-culated values show that the field intensity is increased slightly 7
in some areas and actually decreases in other areas.

JUNE 1985 case the incremental dif ference is so slight as to be hardly meas-urable.
It is planned to measure the field strength before instal-lation and again af ter installation of the 345 kV lines for compara-tive analysis.
As in the past CECO. Will work cooperatively with landowners to mitigate or correct any adverse ef fects caused by the electrostatic field.
Corrective measures will be in accordance with the f ollowing paragraphs.
