1.0 1.1 Purpose An excavation approximately 150 feet in diameter and 70 feet deep will be required for each of the two proposed reactors at Station.

To design the side slopes of the excavation and to estimate the quantity of excavation, it is necessary to determine the frequency and orientation of fractures in the rock. For this purpose inclined borings were made around the perimeter of each of the two proposed excavations.

The core was oriented and the orientation of joints, slickensided surfaces, and foliation was determined.

1.2 Scope Four inclined borings were made around the perimeter of each proposed reactor excavation. The borings ranged in length from 165 to 169 feet, and in inclination from to measured from vertical.

(The bottom of a boring inclined at is at a vertical dif-ference in elevation of 126 feet below the ground surface.)

NW 55SE 60 SW 2.4 Orientation Data Core was oriented from near the rock to the bottom of the hole, with three exceptions: Boring in which orientation starts at 63 ft (inclined length) below the rock surface; Boring in which orientation terminates at ft (inclined length) in a that was 165 ft long; and Boring in which orientation terminates at 42 ft (inclined length) in a that was 165 ft long.

Appendix II is a summary of all the orientation data, and Appendix III contains polar equal area stereo net projections for the features in each borehole.

Fig. 1 is a plot of generalized dip and strike data for joints in each of the borings.

Fig. 2 is a plot of generalized dip and strike data for foliation. As shown on the individual boring logs in Appendix I, the rock at the two re-actor sites does not exhibit much foliation.

Fig. 3 is a plot of generalized dip and strike data for slickensided surfaces.

Fig.

is a contoured plot of the projections of poles for 230 joints measured in the core from borings at Reactor 1; Fig. 5 is a contoured plot of the projections of poles for 93 joints in Reactor 2; and Fig. 6 is a con-toured plot of the projections of poles for 114 slickensided surfaces in Reactor 2.

Fig. 4 shows that there are two dominant sets of fracture surfaces at Reactor No. 1 with strikes and dips roughly as follows (listed in order of decreasing frequency of occurrence):

Figs. 5 and 6 show that there are three dominant sets of fracture surfaces at Reactor No. 2, with strikes and dips roughly as follows (listed in order of decreasing frequency of occurrence):
