- AL I. INTRODUCTION A borehole geophysical logging survey was conducted at Pacific Gas and Electric's (PGE)

Diablo Canyon Power Plant (DCPP) in San Luis Obispo County, California. This survey is in support of a geotechnical investigation for a proposed Interim Spent Fuel Storage Installation (ISFSI). The geophysical logging was conducted in three phases as follows; (1) April 20 and 21, (2) April 23 and 24 and (3) April 28, 2001 by NORCAL Geophysicists William J. Henrich and Dan Jones. Field activities and logistical support was provided by Jeff Bachhuber, John Helms and Charles Brankman of William Lettis Associates, Inc.

The purpose of the survey is to characterize bedrock fracture frequency, calculate fracture orientation and identify bedding attitudes in ten exploratory borings which penetrated the Obispo formation. The following presents a description of the borehole methodologies and results of the survey.

II. SCOPE OF WORK We conducted a suite of geophysical logs consisting of caliper and optical televiewer (OPTV) in ten borings designated as 01 -CTF-A and 01 -A thru -I. Depths of these borings ranged from 58 to 320 feet. This logging was performed in accordance with NORCAL Geophysical Consultants Work Plan, Geophysical Investigation for the DCPP-ISFSI Site dated December 4, 2000.

III. SITE CONDITIONS The study site is situated on a north facing hill slope within Diablo Canyon two to three hundred yards east of the main plant and reactor facilities. The general geology consists of a thin (2-5 feet) layer of alluvium overlying mostly thinly to massively bedded sandstone of the Obispo formation (Tertiary Age). Exploratory boreholes were drilled with a nominal 4-inch diamond core bit (HQ-size) which penetrated the underlying rock to depths ranging from 58 to 321 feet below ground surface. In general, encountered static water levels ranged from about 15 feet above total depth to completely dry conditions. Boreholes were drilled vertically and generally included shallow conductor casing collared into stable bedrock. The ground surface at each borehole was used as the geophysical logging reference datum.

IV. DATA ACQUISITION, CALIBRATION QUALITY CONTROL Geophysical logging consists of lowering a series of instrumentation (probes) downhole to measure borehole environmental and formation characteristics. In this logging phase, our survey consisted of borehole diameter measurements and acquisition of high resolution optical images of the borehole sidewall. Borehole diameter and optical images were made with three-ann Page 1 Diablo Canyon ISFSI E-i 16 of 350 Data Report E, Rev. 0

7w- m87-n caliper and digital optical televiewer probes, respectively. The caliper probe contains spring loaded arms that record the variations in average borehole diameter (in inches) as a function of depth. The optical televiewer (OPTV) probe consists of a fixed CCD camera that records an analog video image of the borehole sidewall wall. A two-dimensional "unwrapped" sidewall image of the borehole is created by a reflecting hyperbolic mirror below the camera and oriented to magnetic north from a reference signal generated by an on-board compass during digitization.

The OPTV probe contains a complete orientation package (3-axis magnetometer and 3-axis inclinometer) that in addition to the north reference, the bearing and inclination of the borehole axis is recorded with the video image. These probes were manufactured by Robertson Geologging, Ltd. and operated with the manufacture's Winlogger-OPTV logging acquisition system. In addition to the probes, the logging system consisted of a PC based control console (Windows 98 OS), thermal printer, four-conductor logging cable and a portable 12 VDC powered winch.

All geophysical log data were acquired in the up-hole direction. Logging speed for caliper runs averaged 10 feet per minute. The data sampling rate was every 0.05 feet. OPTV logging runs were operated at 3 feet per minute at a data sample rate of 0.003 feet. Prior to actual logging, caliper log response was calibrated with a series of known diameters. The value of caliper diameters ranged from 2 to 8 inches. We used primarily 3 different diameters to compute a calibration curve (polynomial fit). Exact calibration measurements relating the probe output (counts per second) to calibration values can be found at the end of Appendix A, Caliper Logs.

We verified OPTV tool's north reference (magnetic north) with a Brunton compass and a probe sleeve before and after each log. This procedure was witness by the on-site QA/QC manager.

Quality control and stability of logging measurements were verified by re-recording or repeating portions of each geophysical log. Our caliper and OPTV repeats were conducted in the lower 25 and 20 feet of each borehole, respectively. These repeats can be found following the main log section in Appendix A, Caliper Logs and Appendix B, Interpreted OPTV Plots. In general, caliper logs repeated by better than 5 percent compared to the main log section except in zones were the borehole breakouts were measured as several inches greater than the nominal bit diameter. OPTV logs were identical with respect to north direction with a maximum of 0.10 feet difference in depth.

V. DATA REDUCTION Continuous caliper data were transformed by daily calibration curves to measured borehole diameter in inches and smoothed with an 11- point center box car filter. These logs have been plotted with the WINLOGGER (Version 2.01) acquisition and replay software. The OPTV logs were corrected for true geographic north by addingl 4 degrees to magnetic referenced directional azimuths in the interpretation software program RGLDIP (Version 5.3) by Robertson Geologging, Ltd.

VI. DATA PRESENTATION 1.0 Caliper Logs Continuous caliper log plots have been presented at a vertical scale of 1 inch equal 10 feet. The repeat caliper section follows the main log section. These plots can be found in Appendix A beginning with Borehole 01-CTF-A and subsequently followed in alphabetical order by Boreholes 01-A through 01-I.

2.0 Optical Televiewer Logs The color OPTV plots images are presented in Appendix B in the same order as the caliper logs with the repeat section trailing the main log section. These OPTV plots contain from left to right; (1) a perspective view of the borehole as a core projection, (2) "unwrapped "oriented OPTV image, (3) arrow (tadpole) plot which represents interpreted fracture or bedding in terms of dip magnitude (Y-axis) and azimuth (direction of the tadpole symbol "tail") and (4) a COMMENT column that describes fracture/bedding features as planar, irregular or discontinuous. The rightmost graph (5) shows a deviation plot of the borehole trajectory in arrow plot form. For the ten borings surveyed, the deviation data indicated all boreholes deviated was less than 3 degrees from vertical. The details of the above interpretation are presented in the respective summary data tabulations (See Appendix C, Interpreted Fracture and Bedding Tables). These tables list depth, dip azimuth, dip angle, number of points (n) nominated along a fracture or bedding trace, classification of a feature as either a fracture (2) or bedding (0), upper and lower depth of the feature trace and borehole deviation in terms of azimuth and inclination at the specific depth of each borehole feature.

VII. INTERPRETATION AND DISCUSSION 1.0 General Borehole Conditions Our caliper logs indicated that borehole diameter for all ten borings was a constant four inches.

Most boreholes, however, showed several breakouts measuring several inches in diameter in excess of four inches and up to several feet in vertical length. These breakouts when viewed by the OPTV logs correlated to highly fractured zones or clay beds. Some of these fracture zones collapsed and blocked transit of probes in Borings 01-A, -E and -I. This necessitated the need to log these boreholes in stages after the blockage was cleared or stemmed with a protective casing.

Over 95 percent of the OPTV logging footage was conducted under unsaturated (dry) conditions.

Cloudy or turbid fluid conditions prevented the acquisition of an interpretable video image in Boring 01-E.

- m wm 1U 2.0 Fracture Analysis Planar orientation of fractures were calculated with the interpretation program RGLDIP Version 5.3 written by Robertson Geologging, Ltd. Within this program, OPTV images are replayed on a PC computer screen. At this stage several interpretation options are available which basically require the interpreter to interactively fit an ideal sinusoidal trace representing a plane to an observed fracture trace. These options are as follows: (1) nominating points along the trace of the fracture, (2) fit a flexible sinusoid to a fracture trace or (3) employing a semi-automated picking procedure whereby the interpreter selects points at the minimum (trough) and the maximum (peak) extent of the observed fracture trace. In the first method, typically 5 to 15 points were chosen along each fracture trace for interpolation. Regardless of the interpretation method, the program at this point mathematically calculates a" best fit"ellipse that represents the plane of the fracture in terms of dip magnitude and dip direction. The ellipse in turn is represented as continuous red sinusoid that has been superimposed over complete or partially viewable fracture traces on the unwrapped OPTV image plots (second plot from the left) as shown in Interpreted OPTV Plots (see Appendix B). Numeric dip angle and azimuth are represented in the adjacent arrow plot. The determination of dip angle assumes that the borehole can be approximated as a cylinder of a constant diameter which for this survey was four inches.

Most fracture features in this survey appeared continuous (360 degrees) across the unwrapped OPTV image plot. However, in highly fractured zones or in log sections containing high angle fractures (60 degrees or greater), only a segment or discontinuous segments of fracture traces were observed. The apparent segmentation of fracture traces maybe related variations cementation and fracture aperture of the fracture or spalling along the intersection of the fracture plane and borehole wall. Though segmented, the program has the facility to interpolate a dip magnitude and dip direction given that a sinusoid overlaps the various segments. Whether continuous or discontinuous, not all fractures traces can be fitted with a simple sinusoid. This is because rock properties are not completely homogeneous with the result that certain rock fractures did not propagate along an exact plane. Also, borehole enlargements and the resulting probe decentralization will geometrically distort the image trace of a fracture feature and thus appear irregular with respect to an overlapping sinusoidal trace representing a best fit ellipse. In these above instances we have noted whether a fracture is discontinuous or irregular in the "COMMENT" column of the Interpreted OPTV Plots.

Not all fractures have been analyzed. As an example, near vertical features such as those shown in Boring 01-I at depths ranging from 119 to 124 feet (see Appendix B) are not interpreted because of the difficulty of fitting a sinusoid to fractures traces greater than 87 degrees. High density, complexly fractured intervals such as the one shown between 135 and 139 feet in the same Boring are not analyzed because the fracture traces, though seen in the OPTV replay, are either too irregular or discontinuous from intervening fracture offsets to be confidently assessed as distinct features.

Page 4 Diablo Canyon ISFSI E- 119 of 350 Data Report E, Rev. 0

- A In the 10 borings analyzed, we identified a total of 643 features of which about 90 percent were classified as fractures (see Fracture and Bedding Table, Appendix C). As described in the above paragraphs, not all fractures were analyzed. This is to say the rock mass is probably more fractured than number of individual fractures indicated in the Table and that the number of very high angle fractures are under represented. Also, as a generalization, most of the fracture dips tabulated exceeded 45 degrees.

3. Bedding Identification Orientation of bedding traces were calculated in the same manner as fractures. The determination of whether a planar or near planar borehole feature is classified as a fracture or bedding is subjective. Bedding on a optical televiewer image is usually displayed as a series of banding or fine laminations where the contrast between individual beds is either tonal or textural. We observed mostly tonal (color) changes that indicated bedding in this survey. An example can be found in Boring 01-I at depths ranging from 172 to 176 feet. Bedding planes here are characterized by variations in color. A continuous green colored sinusoid superimposed on bedding trace represents our interpreted best fit. Bedding attitudes determined by the RGLDIP program at this locale dips show shallow dips ranging from 9 to 14 degrees with dip direction to the northwest. Taking all borings as a whole, the predominate bedding dip angle is shallow (6-14 degrees) with dip direction towards the west-northwest. Bedding features which depart significantly from this general attitude are related sheared clay beds or discoloration due to oxidation.
