SUMMARY

AND CONCLUSIONS The Main Dam is an earth and rockfill dam which is 1550 feet long at the crest and has a maximum height of 108 feet.The Auxiliary Dam is a random earth fill dam, approximately 4060 feet long at the crest with a maximum height of 73 feet.The Auxiliary Separating Dike is approximately 1200 feet long at the crest and has a height of 55 feet.The plant foundation, Main Dam core trench and spillway, and Auxiliary Dam core trench and spillway were cleaned, photographed and mapped at a scale of 1 in to 10 ft.The remainder of the foundation of both dams and the foundation of the Auxiliary Separating Dike were photographed and mapped at a scale of 1 in to 50 ft.All channels were visually inspected as they ere being all mapped excavated. No adverse conditions were found.Photographs of areas are stored in the CP&L files.The Main Dam is.underlain by pre-Triassic igneous and metamorphic rocks consisting of granite, hornblende-mica gneiss, layered-quartz-feldspar gneiss, and mica schist.The foliation generally strikes approximately N55E and dips 30 60 northwest. Joints are typically spaced two to three feet apart and strike northeast and northwest. Several non-capable faults were found in the foundations of the Main Dam structures. Special Reports on these features are in Volume 2 of this report.The plant, Auxiliary Dam, Auxiliary Dike and channels are located in the Durham Triassic Basin and are underlain by Triassic sedimentary rocks belonging to the lower part of the Sandford Formation. These rocks consist of medium-to coarse-grained sandstone, fine-to medium-grained sandstone, siltstone, and shaly siltstone. In many places in the region, these Triassic rocks are intruded by diabase dikes of late Triassic or early Jurassic age.Nevertheless, in the foundation excavations only three narrow dikes have been exposed;they are perpendicular to the Emergency Service Mater Intake Channel.No geologic features were encountered which could adversely affect stability of any of the structures. Grout takes on both dams were very low.Average take for the Main Dam curtain grouting was 0.03 bags/ft.;for the Auxiliary Dam was 0.06 bags/ft.No grout curtain was constructed under the Auxiliary Separating Dike.(Core photographs from primary curtain grout holes and detailed grouting records are on file with CP&L).All aspects of the foundation excavation, clean up, treatment, drilling, and grouting conformed with accepted practice, design intent, work pro-cedures, and specifications. Members of the United States Nuclear Regulatory Commission Earth Sciences staff visited the site on a number of occasions and inspected the work and records.

2.0 INTRODUCTION

This report is a summary of the geology and foundation conditions at the power plant, Main Dam, Auxiliary Dam, Auxiliary Separating Dike, Auxiliary Reservoir Channel, Emergency Service Water Intake and Discharge Channels, Cooling Tower Makeup Channel and other related structures of the Shearon Harris Nuclear-Power Plant, as constructed for Carolina Power&Light Company.The locations of these structures are shown in Figure 1.Initial excavation of the power: plant foundation was begun in April, 1974.and halted in May, 1975;excavation was resumed in 1977 and completed in 1979.Excavations of the Main Dam and related structures foundations were begun in April, 1978 and completed in March, 1980.Excavations for the foundations of the Auxiliary Dam and the Auxiliary Separating Dike were begun in June 1978 and completed in February 1979.Geologic mapping of the found-ations proceeded as excavation progressed at the power plant and at both dams.Drilling and grouting was begun after the completion of foundation mapping in each segment of the dams.

GEOLOGIC INVESTIGATIONS

3.0 PREVIOUS

GEOLOGICAL INVESTIGATIONS Preliminary investigations for the Shearon Hariis Project were performed to evaluite the engineering, geologic and seismologic characteristics of the site and suirounding area.Field exploiation consisted of the follow'ing: a.An engineering survey of tHe site and the suirouiiding area.b.Boring programs which included a preliminary test boring program, borings for structure design, and a boring program in conjuiiction with the Site Fault investigation, for a total of 1250 boriiigs.c.Instillation and monitoring of wells and piezometers. d.A trench excavation program for which 12,000 linear feet'eie dug to supplement the exploratory borings and which was-expanded during the Site Fault investigation. 'I e.Seismic refraction surveys along approximately 5,000 linear feet of siirvey lines.During excavation of the plant foundation a minor normal fault, herein referred to as the Site Fault, was exposed in the Foundation of the Waste Processing Building;A comprehensive investigation of the Site Fault was performed for Carolina Power&Light Company by Ebasco Services Incorporated in order to determine (1)age of last movement of the fault, (2)fault length, (3)vertical and horizontal components of movement of the fault, (4)alignment and attitude of the fault from the plant excavation to and through the Auxiliary Reservoir area.A program of trenching perpendicular to the trench of the fault was carried out to trace the fault beyond the limits of the excavation. Nine core borings were completed in sedimentary rock on both sides of the fault to determine the vertical component of off-set along the fault.Magnetometer surveys were used to locate and trace diabase dikes which served as markers to aid in determining fault displace-ment.Detailed laboratory studies of samples from diabase dikes, associated sedimentary rocks, and undeformed crystals, of secondary zeolites in fault gouge were made to determine thk geochronology of dike emplacement and fault movement.The results of these investigations are described in the report: "Fault Investigation, Shearon Harris Nuclear Power Plant, Units 1, 2, 3, 4", dated February, 1975,and"Preliminary Safety Analysis Report" for the Shearon Harris'roject.

INSPECTION and CONTROL

4.0 FOUNDATION

INSPECTION AND CONTROL All foundations were regularly inspected for CP&L by qualified Ebasco site geologists as excavation and final clean-up progressed to ensure that the specifications, plans, and design intent were being followed.'he site geologists also supervised foundation surface treatment, drilling, and grouting of the dams.As work progressed, when any deviations fiom the drawings and the specifications were required because of field conditions, the owner was informed and necessary Field Change Requests (FCR's)were obtained before work proceeded. Grouting inspectors were provided by Law Engineering and Testing Company from October, 1978 to March, 1979 and by CP&L and Daniel Construction Company from then until the end of the job.In accordance with established CP&L procedures, unusual features and suspected I faults encountered in the foundations were promptly reported to the NRC staff along with submission of a tentative evaluation of the capability of the features.This was followed by an investigation of each feature which was documented by detailed geologic mapping, photography, and, if appropriate, other investigative methods, such as petrographic analysis.When mapping was completed, a second geologist checked the field map and noted discrepancies, if any, for corrections. Final drafts were checked against the original field maps by the person who performed the mapping. Members of the United States Nuclear Regulatory Commission earth sciences staff visited the sites (Photo 1)on a number of occasions and inspected foundation clean-up, mapping, surface treatment, drilling and grouting operations, and records.Dates and personnel involved in these inspections are shown in Table 1.

5.0 GEOLOGY

GEOLOGY 5.1 Geologic Setting The Shearon Harris site is located in the Piedmont Plateau physiographic province.Most of tPis province is underlain by igneous and metamorphic rocks ranging in age from late Precambrian to late Paleozoic, except for several northeast trending linear basins which are filled with Triassic sediments. The power plant, Auxiliary Dam, Auxiliary Separating Dike, and the four channels are all located within)he Deep River Triassic Basin, a northeast trending II structural and topographic basin in the Piedmont Plateau.This basin is almost 100 miles long and 5 to 20 miles wide.It extends from near Oxford in V I~g~I I I I VVV(." I"',V 4 V'4.I 4 Granville County, southwestward to Moore County, 10 miles southwest of Carthage.It is filled by a complex wedge-shaped block of Triassic rocks consisting mostly of claystone, shale, siltstone, sandstone, and conglomerate. These sedimentary rocks are intruded in places by diabase dikes and sills of Triassic-Jurassic age.The Deep River Basin is bounded on the southeast by the Jonesboro Fault, a I northeast-trending diagonal slip fault with a vertical displacement of 8,000 to 10,000 feet and an unknown component of right-lateral displacement. The fault forms the contact between the Triassic sedimentary rocks and the older igneous and metamorphic rocks of the Piedmont Plateau.The closest proximity of the Jonesboro Fault to the power plant is about 4 miles to the southeast of the plant.This fault is inactive, as it is covered in places by undis-turbed sediments of Cretaceous age.The Main Dam is located approximately 3,000 feet southeast of the Jonesboro Fault in an area of pre-Triassic crystalline rocks (Figure 1).These rocks are mostly greenschist-grade metavolcanic rocks and amphibolite-grade gneisses and schists of late Precambrian and early Paleozoic age.5.2 Crystalline Rocks of the Main Dam The Main Dam and its spillway are founded on crystalline rocks located south-east of the Jonesboro Fault (Figure 1).As exposed in the excavations, these rocks are generally hard, strong, and fresh to moderately weathered. Four main types of rock were distinguished for the purpose of foundation mapping.These are (1)granite, (2)hornblende-mica gneiss (3)mica schist, and (4)layered quartz-feldspar gneiss as shown in Figures 2 through 6.5.2.1 Granite Rocks of granitic composition are most common;they underlie most of the left abutment of the Main Dam, most of the upstream part of the diversion conduit, and a major part of the spillway.These rocks are typically hard to very hard, strong, and medium-grained. They are composed predominantly of feldspar (orthoclase and plagioclase) and quartz, with minor amounts of biotite, chlorite, muscovite, and pyrite.They are light gray when fresh, creamy white when slightly weathered, and tan or buff when moderately to PHOTO 2 Granite in Main Dam Diversion Conduit Wall with Schist Interlayer ~a highly weathered. The granites are commonly foliated, although foliation is weak or absent in places.In many places they are interlayered with intricately folded mica-schist and/or hornblende-mica gneiss (See Photo 2).Xenoliths of hornblende gneiss occur'n the granite, especially where foliation is weak or absent.Much of.the highly foliated granite appears to contain indistinct compositional layering.5.2.2 Hornblende-Mica Gneiss Hornblende-mica gneiss is the second most common rock type in the foundation. It underlies much of the right abutment of the dam, the downstream part of the.diversion conduit, and most of the downstream part of the spillway.The hornblende-mica gneiss is a hard, strong, medium-to fine-grained rock com-posed of hornblende with subordinate amounts bf plagioclase and biotite C (Photo 3).Chlorite and pyrite are common accessory minerals.It is gray to black when fresh, bluish or greenish gray when slightly weathered, and rusty brown when moderately weathered. 5.2.3 Mica Schist Mica schist occurs as complexly folded layers 0.01 to 10 feet thick within the granite and as thin layers along joint surfaces within the hornblende-mica gneiss.During excavation, rock.tended to break along these schist layers, resulting in wide exposures of the schist in areas where the layers are horizontal or near horizontal. The schist is soft to moderately hard, weak to moderately strong, moderately weathered, fine grained, highly PHOTO 3 Hornblende Gneiss in Main Dam Spillway

fissile, and composed predominantly of chlorite, biotite;-and amphibole. Some schist layers contain abundant quartz.5.2.4 Layered Quartz-Feldspar. Gneiss Layered quartz-feldspar gneiss occurs in the central section.of the Main Dam core trench, and in a small area at the intersection of the Main Dam core trench and the diversion conduits, and in part of the spillway.This rock is light gray to dark brown, fine to medium grained, moderately hard, I moderately strong, and slightly to moderately weathered. It is characterized by intimate interlayering of gneissic rock composed mostly of quartz and I feldspar with schistose rock composed of biotite and muscovite or, less commonly, hornblende and mica.Individual layers are from 0.01 to 3 feet thick.A micaceous, quartz-rich variety containing a few schistose layers~~is present in the spillway area.The higher quartz content of the gneiss'distinguishes it from rocks mapped as granite.Orientation of foliation and compositional layering in rocks of the Main Dam area is highly variable due to the highly complex nature of the folding which these rocks have undergone. Folding is most apparent in the layered quartz-feldspar gneiss and in mica-schist and hornblende-mica gneiss layers in the granite.These rocks appear to have undergone several periods of folding with isoclinal folding predominating. In most places, the foliation is parallel or subparallel'o the compositional layering.Northeast strike directions and northwest dip directions predominate. Foliation striking north-northwest and dipping southwest is also present in places, but is much less common. Joints are most common in the granite and in the hornblende-mica gneiss.Thc domiiuint jojnt set strikes approximately N60-70 E and dips 50o to 70 to the south.Another set strikes N20-35 W and dips 70 and 90 south-west.Most joints are tight, although a few are filled with clay.Several seeps were encountered along joints in lowest part of the core trench and diversion conduit.They flowed at a rate less than 1 gpm, and most were stopped by grouting.Seepage along joints which were too tight to accept grout will drain into the dam's filter.5.3 Unusual Foundation Features and Faults In accordance with established CP&L procedures, unusual features and suspected faults encountered in the foundations were promptly reported to the NRC staff along with submission. of a tentative evaluation of the"capability" of the feature.This was followed by an investigation of each feature which was documented by detailed geologic mapping, photography, and, if appropriate, other investigative methods such as petrographic analysis.None of these features were covered by construction until they had been inspected by the NRC staff and judged by them to be"non-capable" based on their inspection and their evaluation of the investigation results.During mapping at'the Main Dam, 30 features were reported to the NRC of which 24 were determined to be faults.Most of these faults were only a few tens of feet long with only several inches of displacement. Several schistose zones which pass through the foundation were also reported and investigated. All but one of the reported features were encountered in the right abutment and spillway area, as shown on the included geologic maps.Table 2 lists locations of the features with dates of the reports.The written reports on these features are presented to the NRC are included in Volume 2 of this report.Regardless of the type of feature, it was documented that any fault move-ments occurred prior to or during deformation-mineralization processes which terminated more than 225 million years ago.Thus, none of the features affect the safety of the structures or are."capable" faults as that term is defined'in Appendix A to 10CRF100.5.4 Sedimentary Rocks of the Power Plant, Auxiliary Dam, Auxiliary Separating Dike, Channels and Other Related Structures All of these structures are founded on gently dipping, well consolidated sediments which belong to the lower part of the Triassic Sanford Formation. The.bedrock is sandstone, siltstone, and shaly siltstone. These rocks con-sist mostly of alluvial fan, stream channel and floodplain deposits and are characterized by abrupt changes in composition and texture both laterally and vertically. The thickness of the beds range from a few inches to a maximum of 15-20 feet.Despite the variations in composition and texture, rock masses show no structural weakness.At the project location these sedimentary units strike N5-15 E and dip ranging from 9-17 to the south-0 0 o 0 east.Several north-to-northwest trending, near vertical diabase dikes of Triassic-Jurassic age have intruded the Triassic bedrock in the site vicinity.Bed-

The coarse sandstone is massive in some places, but is prominently jointed in'others. It is sporadically fossil-iferous, containing coal and bone fragments in places.5.4.2 Fine-Grained Sandstone The fine to medium-grained sandstone is typically chocolate brown.It is composed of subangular to subrounded quartz grains with a clay and silt matrix, and is generally fresh to moderately weathered when exposed in the foundations. It is commonly massive with prominent joints.It has gradational contacts with siltstone and medium to coarse-grained sandstone. 5.4.3 Siltstone~~The siltstone ranges from chocolate or purplish brown to bluish or greenish-gray.Most of it is either pebbly, sandy or shaly.Mottling's extremely common.The pebbly variety is generally chocolate brown with light gray, irregular, claystone-siltstone pebbles.A complete gradation exists between the siltstone and the shaly siltstone. Joints are prominent and are present in most areas.When exposed in the foundations the siltstone is slightly to moderately weathered in most places.5.4.4 Shaly Siltstone The shaly siltstone is chocolate to dark brown, purple, green, or gray.It is composed predominently of silt and clay.However, like the siltstone described above, it is sandy and/or pebbly in places.It occurs as massive, poorly bedded layers which range in thickness from several feet to less than 1/2 inch, and commonly forms thin laminae separating beds of other rock types.The most distinguishing characteristic of the shaly siltstone is its susceptibility to slaking.Joints are most prominent in the sandstones and siltstones; they are barely visible and,rarely mappable in the shaly siltstone unit.Three joint sets are present.The two dominant sets are approximately vertical, one striking N40-50 E and the other N20-30 W.A third set strikes north-northwest and dips 55 to 70 to the southwest. Most of the joints are tight and do not extend vertically for more than a few feet.Some joints which were observed during the inspection and mapping, mostly at vation, extended vertically as much as 10-15 feet and blasting.Joint surfaces were generally clean with a the power plant exca-were opened up due to few having a very thin grayish-green clay filling.Some minor seeps were observed along bedding planes and joints.Those at the plant were seasonal with flow rates too low to measure.Those at the Auxiliary Dam generally flowed at a rate of less than 1 gpm.A minor fault, the Site Fault, was encountered during excavation of the plant foundation.. This fault was exposed and mapped in the foundation of the Waste-Processing Building (Figure 7)and in the foundation of the Auxiliary Dam at Station 4+23 (Figure 8).The fault strikes nearly east-west across the plant and Auxili'ary Reservoir area.The fault surface is somewhat undulatory with dips ranging from vertical to 55 southward. The south side of the fault is down thrown,'ith a vertical component of movement between 80 and 100 feet.Maximum horizontal offset could not be determined, although offset of dikes intruded during the period of movement are offset by an amount ranging from a minimum of one-half foot to a maximum of 13 feet.Drag folding of Triassic beds is present on the hanging wall of the fault.A detailed investigation of this fault, described in the"Shearon Harris Fault Investigation Report", determined that the fault is a minor tensional fault whose last movement was prior to 150 million years ago.No other significant structural features were found.

and SURFACE TREATMENT

6.0 EXCAVATION

AND SURFACE TREATMENT Foundations for the plant, Main Dam, Auxiliary Dam, Auxiliary Separating Dike and the four channels (Auxiliary Reservoir'Channel, Emergency Service%later Intake and Discharge channels, and cooling tower make-up water intake channel)and other related structures were excavated and treated in accord-ance with specifications CAR-SH-CH-4 and CAR-SH-CH-8 (FSAR Appendix 2.5.I).6.1 Main Dam Main Dam Construction activities in the Main Dam area began with excavation of a segment of the spillway to allow early relocation of the bridge for the Norfolk Southern Railroad.At the dam site, a diversion channel was qexcavated immediately northeast of the existing Buckhorn Creek bed, the creek flow was diverted through it, and cofferdams were then constructed adjacent to the diverted creek.Next, the foundation of the diversion conduits was excavated, cleaned, and geologically mapped.The diversion conduits were constructed, the cofferdam was removed and the creek re-diverted through the conduits.Finally, excavation of the remainder of the core trench, the dam shell, and spillway were excavated. The foundation of the Main Dam was excavated to weathered rock (defined as"material which cannot be removed on a production basis with the blade of a D-8 tractor-dozer"). Several high"knobs" in the right abutment and at one location in the left abutment were removed by light blasting.The foundations of the core trench, the diversion conduits, and,the spillway were excavated to design grade or at least to suitable rock (defined as"the rock material that cannot be.removed on a production basis with a single-tooth ripper of a D-8 tractor or equivalent").After initial excavation was complete in the diversion conduits, core trench, and spillway floor and walls, the foundations of the seismic Category I structures (i.e., areas to be mapped at a scale of 1 inch to 10 Eeet)were mucked out by a front end loader.Ramaining loose materials were cleaned using a Gradall, hand tools, and compressed air or compressed-air-water jets.Loose blocks were removed by picks or by barring and wedging, and small pockets of mud were cleaned out using trowels and shovels, see Photo 5.In general, a 50-foot reach of core trench was cleaned at a time, although on occasion a 100-foot segment would be cleaned.After a reach was cleaned, a survey crew laid out a pattern of grid marks on 10-foot centers in preparation for mapping by a qualified geologist (see Photo 6).Compositional layers, joints, fractures, faults, veins, and other mappable features in the foundation were located with respect to the grid marks by measuring with a tape.Attitudes of planar features such as joints and foliation were mapped measured with a Brunton compass.All features were mapped at a scale of 1 inch to 10 feet as presented on Figures 2, 3, and 4.Areas containing faults or other anomalous features or requiring special detail were mapped on a scale of 1 inch to 5 feet as shown in Volume 2.Foundation areas not mapped in plan at a scale of 1 inch to 10 feet, such as the rockfill foundation were mapped at a scale of 1 inch to 50 feet after these areas were cleaned with a bulldozer blade and, as necessary, a PHOTO 6 Hand Cleaning of Main Dam Core Foundation <<35>>

Gradall and a grid was surveyed on 25 or 50-foot centers.The embankment foundation is shown on Figure 6.As mapping of each reach of the foundation was completed, photographs were made of the foundation surface and are now maintained in CP&L files.After.mapping of the core trench foundation was completed, open joints and fractures were slush grouted as required.Consolidation holes and curtain holes were drilled and grouted in accordance with specification CAR-SH-CH-11. Finally, after further clean-up by hand and compressed air and/or water jets, dental concrete was placed to provide a smooth surface and to achieve the specified maximum 1/2:1 foundation slope (see photo 7).In areas in which the rock surface was extremely uneven, placement of dental concrete preceeded drilling and grouting activities to aid mobilization of equipment.

6.2 Power

Plant Excavation for the Shearon Harris Plant structures was started in 1974 halted from 1974 to 1977, and continued to completion in 1979.The plant excavation includes the foundations for the waste processing build-ing, four turbine generator buildings, fuel handling buildings, four reactor auxiliary buildings, four containment buildings, and four tank buildings, (Figures 7 and 9).It has a maximum lateral extent of approximately 925 ft.in the north-south direction and 990 ft in the east-west direction, and encompasses a total area of approximately 837,500 sq ft.Floor elevations of the various levels within the excavation range from elevation 234 ft to PHOTO 7 Placement of Dental Concrete in Main Dam Core Trench

~~elevation 179 ft.The total volume of the excavation is approximately 1,200,000 cubic yards.Plant excavation began with the leveling of the ground surface in the plant area to elevation 260 ft.Depressions in the surface outside the plant island were brought up to grade with random fill consisting of local sedimen-tary rock material and residual soils.Structure foundations were excavated to ripper refusal by common excavation using bulldozers and scrapers.The excavation was completed to final grade by controlled blasting in successive lifts and by using power shovels and backhoes to load the excavated and blasted rocks onto trucks for removal up through an access ramp cut at the south end of the excavation. Slopes were excavated through the overburden at 1:1.Slopes in bedrock were excavated at 1:4.Rock slopes were shaped by presplitting in accordance with specifications which did not permit heavy blasting closer than 3 feet to the rock which forms the final foundation of concrete structures. Pre-splitting did not completely preserve the rock surface of the slopes, especially in the west wall of the excavation, because adverse jointing across bedding planes, which dipped toward the excavation allowed small blocks to slide down bedding planes, toward the excavation. The situation was somewhat aggravated during the period from late 1974 to early 1977 when excavation was halted.All loose blocks of rock were removed when excava-tion work was resumed.Weathering of fine-grained rocks exposed in the excavation during the period of project delay did not exceed several inches below the exposed surface.The surface layer formed by the uppermost disintegrated rock tended to protect the underlying material from further rapid advance of the weathering process.However, weathering along natural joints, fractures, and bedding planes in the fine-grained rocks necessitated some additional excavation of foundation areas to assure adequate intact condition of the rock prior to placement of the concrete seal coat.The excavated rock was replaced by equivalent concrete so that the stability of structures founded on the rock was not affected.Treatment methods used for foundation protection after excavation included slush grouting, shotcreting, and placement of vertical and horizontal drain pipes as well as placement of seal coating.Following final excavation, open joints and fractures, including those due to blasting, were filled with slush grout and the surface was covered with a thin coating of Class F mortar.Then protective concrete seal mat or, in certain instances, foundation structural concrete mat was placed over com-pleted foundation surfaces.Walls of the excavations were protected by spraying shotcrete on meshwire.Drain pipes were placed at the location of seeps and other necessary places to prevent excessive hydraulic build-up (see Photo 8).In Units 3 and 4, a vertical mat was formed and poured with concrete to protect the walls.During construction, a geologist resided at the site throughout the cleanup of the excavated surfaces to assure that structure foundations were prepared in accordance with applicable design and specification requirements and to document the foundation conditions by preparing a geologic map.The area geologist inspected all cleaned areas, made recommendations for any necessary remedial action and approved all surfaces prior to concrete placement. PHOTO 8 Drainpipes in Wall of Plant Excavation Prior to geologic mapping, all loose materials were removed from the excavated surfaces by backhoe, Gradall, hand tools, and air lances (see photo 9).Then a mapping grid established by a survey team and the geologic map was then made of the surveyed segment at a scale of 1 inch to 10 feet, as shown in Figures 7 and 9.6.3 Auxiliary Dam The foundation for the transition filter and the random rockfill for the Auxiliary Dam was excavated to weathered. rock.The foundations for the clay core (including cut-off trench)and the Seismic Category I structures of the spillway were excavated to suitable rock to design grade.After initial stripping and ripping of the cut-off trench and spillway by a bull-dozer, final grade for the spillway, was achieved by controlled blasting in successive rock lifts.A total of 402,000 cubic yards of material were removed form the cutoff trench and 559,000 cubic yards from the spillway area.Following completion of initial excavation for the cut-off trench and the foundations for Seismic Category Class I spillway structures, these areas were mucked out with a Gradall, blown with air lances, and hand cleaned prior to mapping (photo 10).Cleaning proceeded in 50 to 100-foot reaches.After thorough cleaning of each reach of foundation, it was gridded on 10-foot centers by surveyors and mapped by a qualified geologist at a scale of 1 inch to 10 feet.The core trench walls in the vicinity of the Site Fault were also mapped at a scale of 1 inch to 10 feet.Photographs were made of the foundation surfaces after mapping was complete.The geologic map of these foundation areas is shown in Figure 8. PHOTO 9 Final Clean-up of Foundation in Power Block Excavation I-F 4~F FF PHOTO 10 Hand Cleaning of Auxiliary Dam Foundation 44-Foundations for the remaining areas of the clay core, outside of the cut-off trench, spillway and the foundation for the dam's transition filter and random rockfill were excavated by a bulldozer'and Gradall to weathered or firm residual soil, and mapped at a scale of 1 inch to 50 feet.The geologic map of these'areas is shown in Figure 10.Methods used for foundation treatment for the Auxiliary Dam and spillway were generally the same as those described for the Main Dam.The Site Fault, exposed as anticipated at Station 4+23, was the only unusual feature encountered during excavation. This fault was demonstrated to be non-capable after an extensive investigation which is described in the Shearon Harris Fault Investigation Report and the Shearon Harris FSAR.The fault was treated by a special grout pattern, as discussed in subsection 7.3.2.~~~6.4 Auxiliary Separating Dike The foundation of the Auxiliary Reservoir Separating Dike was excavated to firm residual soil, as required by specifications, in the shallower parts of the excavation, and to~eathered rock in the deeper parts.After excavation, the foundation surface was cleaned by a bulldozer, mapped geo-logically at a scale of 1 inch to 50 feet, and then photographed. No faults or other unusual features were observed and no foundation treatment was required.A geologic map and section of the Auxiliary Reservoir Separating Dike foundation is shown in Figure 11.

6.5 Channels

Each of the four channels was excavated to design grade and slope by scrpers and dozers with rippers.Shallow blasting was required in portions of these channels.. The channel excavations were inspected by a qualified geo-logist;no geologic mapping of the excavations was required.Diabase dikes were exposed at three locations in the Emergency Service Water Intake Channel.Concrete protection of the inverts and walls of the channel was provided at the dike locations.

6.6 Structures

Outside of the Plant Excavation Excavation for five structures outside of the plant excavation was begun in 1979 and completed in 1980.These structures include: 2 diesel generating buildings, the diesel fuel oil storage tank building, the emergency service water screen structure, the emergency service water system intake structure, and the emergency service water system discharge structure. The foundations areas of these structures were stripped by scrapers, ripped by dozers, and blasted as.needed to the design grade.All of the foundations were mapped at a scale of 1 inch equals 10 feet.The location and geologic map of the foundations are shown in Figure 9.

GROUTING

7.0 FOUNDATION

GROUTING Grouting in the cut-off trenches at both dams was completed with neat cement in accordance with specification CAR-SH-CH-11. Consolidation holes were drilled to 20-foot depths on 10-foot centers as specified on Drawings CAR-2167, G-6246 and G-6274 (Photo 11).Primary curtain holes were cored and logged to 50-foot depths on 40-foot centers, staggered 5 to 10 feet off the centerline of the dams.Secondary curtain holes without core recovery were drilled along the centerline between the primary holes.All primary and secondary curtain holes were water pressure tested in five stages and then grouted in three stages.Consolidation holes were water pressure tested as needed and grouted in one stage as required.Check holes were drilled and grouted for both consolidation"a'nd the curtain grouting programs as re-quired to assure an adequate foundation and cut-off for the structures. All holes were backfilled when grouting of an area was completed. As anticipated, grout takes at both dams were, with few exceptions, very low.Most of these exceptions were caused by surface leakage.Grouting was begun during the fall of 1978 and continued intermittently through the winter of 1981.Grouting at the Auxiliary Dam was completed-in mid-August, 1979 and at the Main Dam in January 1981.Grouting on both dams was performed by the Layne-New York Company, Inc.with the exception of the right end of the Main Dam core trench where 7 holes were drilled by percussion and grouted by Law Engineering Testing Company.

7.1 Personnel

and Equipment The overall grouting operations were supervised by qualified Ebasco geologists for the owner.Up to six inspectors monitored the contractor's work and kept records.The contractor's maximum crew consisted of two supervisors, two foremen, four operators, one mechanic and six laborers.Consolidation holes, secondary curtain holes, and check holes at the Auxiliary Dam were drilled using three Model 250 Ingersol-Rand air tracks on which the contractor mounted CP-65 drills.EX drill rods of 1 3/8-inch outside diameter were used with AX diamond bits.At the Main Dam, all except primary, curtain holes were drilled by one Ingersol-Rand and one Gardner-Denver air track percussion drills (Photo 12).At both dams, a C-50 Ingersol-Rand jackhammer was used for setting nipples.Primary curtain holes were core drilled with CME-50, Mobil B-30, Mobil B-56 and Joy D-12 rigs using an NX diamond bit, w'ireline, and double tube core barrel (photo 13).Cores were logged, photographed (photo 14)and stored at a storage building on site.The contractor operated up to four grout plants.Grout was mixed in high speed centrifugal mixers.Two Acker grout plants, each had a 10-cubic foot mixing capability, a 12 cubic foot agitator capacity, and were equipped with L-2-6 Moyno pumps (photo 15).The third grout plant had a mixer and an agitator, each of 18 cubic foot capacity and L-3-8 Moyno pumps (photo 16).The fourth grout plant had a 12 cubic foot mixer, a 16 cubic foot agitator, and an L-36-6 Moyno pump.Rockwell water flow meters, and Ametek pressure gauges, both calibrated by the owner, were used for water pressure testing and grouting operations.

Portland cement was certified by the manufacturer as meeting the criteria set forth in specification CAR-SH-CH-11. No sand, bentonite or chemical additives were used in the grout mixes.7.2 General Procedures As noted previously, all drilling and grouting procedures were done in accord-ance with Ebasco specification CAR-SH-CH-11 and CPGL work procedures TP-31.In case of any conflict between these, the specification governed.Two or more rows of consolidation holes, 20 feet deep, were spaced on a 10-foot grid as prescribed by design drawings CAR-2167, G-2646 and,G-6274. Angle holes were assigned at the discretion of the qualified geologist to intercept prominent joints, although virtually all of the holes at the Auxiliary Dam were vertical to intercept bedding and jointing.Vertical joints at the Auxiliary Dam were no more than a few feet deep and cut the bedding planes.Fifty-foot-deep primary curtain holes were drilled every 40 feet, alternating 5 to 10 feet upstream and downstream of the center-line.Fifty-foot-deep secondary curtain holes were split spaced along the centerline between each primary hole.Tertiary and quaternary holes were split spaced as required., Figures 12 through 15 illustrate the location of all curtain and consolidation holes with respect to the dams.Prior to drilling, threaded grout nipples, 22 inches long with a 2 or 2 1/2 inch diameter (4-inch diameter for primary curtain holes), were set into the rock or dental concrete using neat cement.*At the'Hain Dam this procedure was later modified to allow setting the nipples after percussion drilling because of difficulties of inserting drill bits into the nipples due to the irregular rock surface.Each hole was thoroughly washed within 48 hours prior to grouting.All curtain holes were pressure tested in five stages;40 to 50 feet at 40 psi, 30 to 50 feet at 30 psi, 20 td 50 feet at 20 psi, 10 to 50 feet at 10 psi, and 0-50 feet at 5 psi.Selected consolidation holes were pressure tested in one stage at 5 psi, at the discretion of the site geologist. Consolidation holes were normally grouted in one stage using an initial mix of 6:1 (six cubic feet of water to one cubic foot of cement (photo 17).In some instances, an initial mix of 4:1 was used.If necessary, the grout mix was gradually thickened to a maximum of 1:1.During consolidation grouting, excessive surface leakage was the major cause of some high rates of"grout take", especially at the Auxiliary Dam.Surface leakage was controlled by caulking with wooden wedges, oakum, burlap, thickening the r 0 mix, and in some cases, by placement of dental concrete.To prevent PHOTO 17 Monitoring Grout Header at Auxiliary Darn but in all cases refusal was obtained at the specified pressure.When the rock surface was decomposed, contributing to the leakage problem, grouting was done using a packer set 1 to 3 feet below the surface instead of hooking up to the nipple.After the completion of grouting, and prior to placement of impervious embankment, such surface rock was removed.In a few other cases where surface leakage occurred in essentially sound rock, a packer was set 5 to 8 feet below the surface and the bottom of the hole was grouted as usual.The packer was then moved to the top of, the hole and the hole was grouted using a thicker mix to control leakage.Curtain holes were packer grouted, from the bottom up, in three stages: 30 to 50 feet, 15 to 50 feet, and 0-50 feet.The grouting pressure used for each stage was 30, 15, 7 psi, respectively. The initial mix for all curtain holes was 6:l.The refusal criteria for both consolidation and curtain grout holes was a rate of grout take less than or equal to 0.5 bags of cement per hour sus-tained for a period of at/east 10 minutes at the maximum pressure for each stage.At least two check holes were assigned approximately five feet from any consolidation hole that took more than 10 bags of cement.Additional curtain grout holes (tertiary and.quaternary holes)were drilled, washed, and grouted adjacent to any secondary or tertiary curtain hole for which the average grout take of any stage exceeded one bag of cement per 10'foot of hole.These check holes were drilled as deep as the stage which had the excessive grout take. After grouting was completed, holes were backfilled with grout and the nipples cut off.Throughout the drilling and grouting operations the core trenches of both dams were monitored for uplift.This was accomplished by setting a 2 1/2 inch diameter, 2 foot length of steel pipe with 6 to 10 inches of stick up, every 75 to 100 feet along the dam's centerline for use as an uplift gauge.These pipes were painted bright orange and protected from damage during equipment mobilization. The pipes were surveyed before, during and after the grouting of each reach.Particular attention was given to areas with high grout takes.The surveys revealed no uplift of the gauges.The minute, random v'ariations in elevation which were observed all fall within the measurement error of the survey.7.3 Grouting Results 7.3.1 Main Dam The grouting results for both consolidation and curtain holes are summarized in Table 3.Figure 12 is the plan view of consolidation holes and Figure 13 is the plan view and the cross section of the curtain holes projected to the centerline of the dam.Logs of the primary curtain holes are presented in Volume 3..Color sgides were taken and are stored in CP&L's Documentation Section at the plate site.In general, the amount of grout injected into each hole was small.The average take for a consolidation hole was 0.02 bags of cement per foot drilled and for curtain holes was 0.03 bags of cement per foot drilled.A total of 19,515 linear feet of consolidation holes and 5,253 linear feet of curtain holes were drilled.A total of 554 bags of cement were required for grouting,and 908 bags of cement for backfilling the holes.The maximum take was 37 bags in consolidation hole number 37E, and 36 bags in curtain hole number C3SD.A few high grout takes were the result of surface leakage and movement of grout along joints and schistose zones.The generally small grout takes for this dam site suggests that most of the joints are tight or completely healed.Water pressure tests only were conducted for many of the consol-idation holes because of the large number of tight holes.Xn accordance with the specifications, holes whose, water pressure tests indicate water takes of less than 0.25 gallons per minute were backfilled but not grouted.Some holes with low water take were grouted, however, these did not take any grout.7.3.2 Auxiliary Dam Grouting results of both consolidation and curtain holes are summarized in Table 3.Figure 14 is the plan view of consolidation holes and Figure 15 is the plan view and the cross section of the curtain holes projected to the centerline of the dam.Logs of primary curtain holes are presented in Volume 3.Color slides of the cores were taken and stored in CP&L's Documentation Section at the plant site. Generally, the amount of grout injected into the holes was small if there was no surface leakage.Grout travel was along the surficial joints and bedding planes in more competent rock.Where shaly siltstone was exposed, grout leakage was commonly encountered because the rock tended to decompose and slake when alternate wetting and drying occurred.Difficulties in caulking these areas was due to the nature of the rock and in some cases V necessitated placement of dental concrete.Because surface leakage was commonly encountered in the shaly siltstone at the Auxiliary Dam, water pressure testing of consolidation grout holes was not a'reliable indication of the grout take for a hole.Therefore, all but a few holes in each reach were grouted without being water pressure tested.The area in which the Site Fault crossed the core trench was treated by a special grout pattern.As shown in Figure 15, six additional curtain holes were drilled and grouted" in the fault zone.Grout takes of these holes were small, as anticipated. The average take for consolidation holes was 0.07 bags of cement per foot drilled and for curtain holes was 0.06 bags of cement per*foot drilled.A total of 20,650 linear feet of consolidation holes and 11,980 linear feet of curtain holes were drilled.A total of 2,113 bags of cement were required for grouting and 539 bags of cement for backfilling the holes.The maximum take was 99.8 bags in consolidation hole number 30A5 which was largely due to surface leakage and 25.0 bags in curtain hole number U104P.

these are old bands of deformation. 21.The smaller kink bands do not pass from the granite through to the mica schist zones.The larger kink bands do appear to pass through from the granite into the mica schist zone.Discrepancies between the foliation in the granite and the mica schist are probably functions of more intense deformation in the mica schist and a type of refraction of the foliation. 22.Zone of highly weathered rock near the top of wall.The mica schist weathers much more readily than the surrounding rock.23.Foliation: 033,55 NW;kink bands: 040,40 SE.24.Foliation: 000o,30 W.25.Orientation of mica schist zone: 020, 60 NW;the foliation in the mica schist and (elsic volcanics is much better developed and more steeply dipping than in the surrounding granites.26.Zone of highly weathered rock.27.Joint crosses schist zone without any offset.28.Foliation: 355,25 SW.29.Bottom of wedge of morc highly weathered rock.30.Zone of ductile shear strain;a joint has developed along the zone'1.Joint filled with quartz, small shear zones present.Several joints intersect here, forming blocks of granite rock.32.Weathered and fractured rock.Some weatheredmica schist in an open joint.Zone of jointed/fractured and weathered rock.Some jointed/fractuied granite rock aIong the edge of mica schist zone;more highly weathered than surrounding granite.Attitude of mica schist zone: 042, 44 NW;the foliation in the granite becomes more intense with proximity to the mica schist zone and also dips more steeply than the foliation further away from the mica schist zone.Foliation of granite several inches from mica schist: 005, 50 NW;foliation of granite three feet from mica schist: 005, 28 NW.The granite in this area contains pieces of baked country rock.There are several ductile shear zones present in the granite.In places it appears that the more steeply dipping foliation in the granite is overprinted on the less steep foliation. 37.Joint orientation: strike 067, dip varies from 80 NW to 80oSE.38.Offset of a ductile shear zone in granite by two smaIl fractures which die out in several feet.Offset is 2 inches along one fracture and 1 inch along the other.These fractures do not offset any major joints./See derail sketch et end of Key/.39.Foliation of the granite within the mica schist zone is quite variable in orientation: 050,55 NW;028,60 NW;050, 58 NW;020,50 NW.Orientation of foliation inmica schist: 048,60 NW.40.Joint orientation: 058,75 SEd foliation: 020,38 NW;major joint orientation: 065,35 NW.41.a)Joint orientation: 005, 60 NW;b)joint orientation: 068,70 SE;granite foliation: 00,45 NW;'orientation of mica schist zone: 015,66 NW;foliation of mica schist: 005, 58 NW.42.Joint orientation: 070,80 SE;foliation:'008,40 NW.43.Mica schist zone: 352, 70 SW (local dip near quartz).44.Jointorientationivaries): 042,60 NW;041,52 NW;338,30 SW.Foliation: 025,44 NW.45.Granite boudins enclosed in mica schist.46.A major area of mica schist with many highly deformed granitic pods and boudins included within.Generally, the foliation of the schist is concordant with the boundaries of the boudins.Discordance was probably caused by some late rotational movement of the boudin, or possibly because the boudins were originally part of granite units folded in with the mica schist.There is a good deal of flattened/sheared granitic material enclosed within the mica schist.47.Zones of mica schist with interfoided and boudinaged granitic rock.There are many tight and isoclinal folds present in this mica schist.These zones are more highly weathered than the surrounding granitic rocks.48.Foliation: 015,38 NW.49.Joint face Iface of slope): 318,45 NE.50.Orientation of joint with weathered granite present in it: 080, 43 SE;foliation: 022, 30 NW.51.Orientation of mica schist zone: 024, 46 NW.Folds in mica schist: Axial Plane: 050o, 42oSE;Axis: 30 to 194,'xial Plane: 042, 37 SE;Axis: 24 to 192.Micaceousschistosity: 045,40 NW.52.Many fine, steeply dipping joints in this area.Joint orientations: 065, 70 SE;062, 85-90 SE.Some of these terminateat themica schist unit and some cut through the mica schist.53.Joint orientation: 065,72 SE;085,45 NW;010,60 NW;foliation: 018,42 NW.54.Joint orientation: 048,65 SE;foliation: 002,40 NW.

Dear Mr.Denton:

In response to your staff's request dated November 29, 1978, concerning additional work required on the schist-granite contact at Station 2+55 in the main dam diversion conduit wall, field and laboratory studies were undertaken to address the following points: I.A field analysis of structures along and across the contact was conducted to define the nature of the contact mesoscopically. .(This part of the study was to include analysis of folding and any other existing deformational features along and across the contact.)II.A laboratory analysis was conducted of thin sections cut from specimens taken across the contact to define the nature of the contact microscopically. Minimal data'required were identification of key minerals, and determination of the time of formation and the timing of last deformation of.the key minerals.E This report presents the data obtain d from the field and laboratory studies which bear upon definitgon of the nature of the schist-granite contact.I.Pfi.eld.Analysis All structures observed in the field that bear a direct relationship to the schist-granite contact are ductile deformation features and hence the result of relatively deep-seated, non-brittle type fail'ure conditions. Any movement accompanying this ductile deformation would ha.e been a ductile-type response closely related to the folding and metamorphic histories. Results of the field analysis of this contact may be summarized as follows: 1.Only ductile deformation is apparent at or along the contact.There ie no mesoscopic evidence for brittle failure in the granitic rock, only a strong foliation developed in response to duc'tile deformation and/oi movements. There are no dis-tortions of schistosity in the schist on the mesoscopic scale which could be equated with a response to brittle deformation (i.e., faulting)at o-along the'ontact. 411 Fayr.uovrllr: Strcel~P 0, Box 1001~Arrlcrgir. N.C.27G02 2.The contact itself is not planar but irregular. The planar appearance of the contact on the map (Figure 1)is a function of the map scale and not inaccuracies in the mapping.Lithologic units are not truncated at this contact, which represents only the boundary between lithogically distinctive rock and layers of schist.3.4.The micaceous layer at the contact is not unique.Layers of similar compdsition are found in the schistose zone alternating with sandy schist and granitic material in bands which are parallel to compositional layering in the zone.(The micaceous unit at the contact pinches and swells to indicate a response to ductile deformation.) \Fractures do not cross the thick schistose zone in the diversion conduit wall because of the ductility contrast between the schistose zone and the surrounding granitic rock.(Mapping of the diversion conduit floor indicates that fractures do cross the schist where it is thinner.)See"Main Dam Plan Geologic Map of Diversion Conduit Sta 2+50 to 4+05" (Figure 2A of the report submitted to you on November 27, 1978, concerning the same schistose zone.)5."Fissility" of the granitic material at the contact is the result of weathering of the foliated granitic rock.6.Clayey material along the contact, in the schist, and around granitic boudins is the result of weathering of potassium feldspar, and is not fault gouge material.II.Laboratory Thin Section Analysis Four specimens were collected for preparation of thin sections as indicated on the attached map of the diversion conduit wall (Figure 1).These four specimens were labeled as follows: PSHMD-Pl-weakly foliated granite away from the contact l/SHMD-P2-strongly foliated granite at the contact 8SKG)-P3-micaceous schist at the contact fISHMD-P4-sandy schist away from the contact The specimens were collected sp"cifically to make possible the preparation of thin sections for investigation of mineralogy and microscopic deforma-tional textures'at and near the granite-schist contact.Thin sections were cut perpendicular to the foliation surface in order to provide the best orientation for observing microscopic deformational textures.A.Sections S19iD-Pl and P2 These sections from the granitic material showed that the key constituent minerals are quartz, feldspar, and biotite.Textures and mineralogy suggest that these minerals are of igneous origin, although they probably have been affected by regional metamorphism. Hr.Harold R.Dcnton-3-January 19, Januar 19, 1979 Sectinn SHMD-Pl indicates that the granitic rock away from the~contact is weakly foliated and contains quartz grains which are weakly strained as illustrated by undulatory extinction. The quartz grains show no elongation, crushing or grinding.Most of the few existing microcracks are healed, and the quartz-feldspar grains are characterized by interlocking grain boundaries of the type similar to that commonly noted in igneous intrusive rocks (Figure 2).Section SES-P2 indicates that the rock at the contact contains elongated quartz veins alternating in micro-layers with'eldspar-biotite.Quartz grains are not crushed, granulated, or sheared and microcracks in the quartz are scarce and commonly healed when present.Quartz grains appear slightly more strained here than farther from the contact as evidenced by the increased develop-ment of undulatory extinction..The fabric observed is that which ,is characteristic of granitic rocks which have been deformed under deep-seated, ductile conditions. The microscopic textures reinforce the mesoscopic observations of the definite lack of brittle failure (i.e., faulting)along the contact.These textures bear out the ductile nature of the fabric developed in the granitic rock at this contact (Figure 3).B.Sections SHMD-P3 and P4 These sections from the schistose zone showed that the key constituent mineral within the micaceous schist and sandy schist is mica with varying amounts of quartz and feldspar.The key minerals are the result of mineral growth under thermal condi-tions accompanying regional metamorphism. There are no microscopic textures to suggest distortion of schistosity related to brittle deformation (i.e., faulting)along the granite-schist contact.The microscopic fabric observed is a normal metamorphic foliation marked,.by planar alignment of mica, quartz, and feldspar (Figure 4).The texture of Section SHMD-P3 is similar to that shown for Section SHlQ)-P4.The weathered nature of specimen SlQiD-P3 made it impossible to acquire a suitable photomicrograph of the thin section which was cut from SK'H)-P3.Based on the above information and the information. submitted to you previously, the schistose zone located at station 2+55 of the main dam diversion conduit wall'cannot be described as a"capable" fault as the term is defined by 10CFR100, Appendix A.Yours very truly, RGB/mf Attachments M.A.McDuffie Senior Uice President Engineering &Construction Mr.James P.O'Reilly~~bcc: D.L.Bensinger (w/o f igures)S.HcHanus (v4/0 4l y MeS)R.E.Jones (w/o f igures)A.Lucas H-l/A-2d Figure 1 LIST OF FIGURES Map of diversion conduit wall indicating locations of specimens collected across the schistose zone at Station 2+55 for preparation of thin sections.Figure 2 Photomicrograph illustrating interlocking boundaries of quartz and feldspar grains in Section SAG)-Pl.Note that the mineral grains show no elongation, crushing, or grinding although the specimen is weakly foliated.(Crossed nicols.Magnification of 3.1X.)Figure 3 Photomicrograph illustrating elongated quartz with alter-nating micro-layers of feldspar-biotite on Section SHMD-P2..Only ductile deformation is indicated.

Dear Mr.Denton:

On November 9, 1978, Carolina Power&Light Company (CP&L)informed members of your staff of the existence of a 60-foot geologic anomaly located at Station 3+10 in the Shearon Harris Nuclear Power Plant (SHNPP)main dam core trench.On November 16, 1978, CP&L reported that the geologic anomaly had been subdivided into two distinct geologic features, Feature A and Feature B.Also, on November 16, 1978, CP&L notified the'Staff that a third geologic anomaly, Feature C, had been identified in the main dam core trench.Your staff requested that we pro-vide verification of last movement, photographs, and mapping of these~~~~anomalies for review.This report.covers Feature A and Feature B;Feature C will be covered by separate report.The main dam and spillway are to be constructed in gneisses and schists of the North Carolina Piedmont.These rocks are considerably older than the Triassic sedimentary rocks which underlie the power plant (i.e., possibly 600,000,000 as opposed to about 200,000,000 years old).Prior to the depositi'on of the Triassic sedimentary units, the litho-logies constituting the Piedmont were deeply buried and subjected to several periods of deformation. The burial and deformation changed the original rock units to the gneisses and schists now exposed.In addition, the rocks were jointed, folded, and faulted, which permitted the in-trusion of many granitic dikes and quartz veins.During the Triassic period and somewhat earlier, Piedmont rocks were unearthed by erosion, and the erosional debris was deposited in basins created during the Triassic by ten-sional stresses.Since the Triassic, the area has been under no major, tightly deforming regional tectonic com-pressive stress.Hence, most deformational features in the Piedmont rocks,,such as faults and folds, must be older than the beginning of the Triassic period (i.e., greater than 225,000,000 years old).V IVI T~, P'"t;P.i,;n~:.'ili::ttr: ~.~v c)p~1551~Rah'iqh t4 C'.o02 Mr.Harold R.Denton November 29, lq78 Samples of core drilled from the gneiss at the main dam site and two nearby locations have been radiometrically dated, as reported to the Nuclear Regulatory Commission by Carol'ina Power&Light Company in"Shearon Harris Nuclear Power Plant, Fault Investigation: Responses to Mr.W.R.Butler's letter of May 16, 1975, Question 9." The dates prove that the gneiss was heated most recently more than 250 million years ago.This heating was due to the intrusion of granitic plutons'throughout the Piedmont about 300 million years ago, and marks the end of the last period of regional meta-morphism.At most places within the Piedmont, regional com-pressional stresses associated with metamorphism resulted in folding and jointing of the rocks, injection of quartz veins, and minor faulting of the veins (See"Final Geologic Report on Brecciated Zones, Catawba Nuclear Units 1 and 2, Duke Power Company, March 1, 1976, and January 31, 1977")." Rock at the south side of the core trench from sta 2+90 to 3+40 is a fractured, fine-grained hornblende gneiss.The bottom of the core trench has been excavated to a depth where the rock is generally fresh to slightly weathered but with local areas of moderately weathered rock.Fresh rock is moderately hard and dark gray.In the southeast corner of the core trench a spherical dome has formed due to exfol'iation weathering of the'neiss. The gneiss contains scattered veins of quartz and of a green mineral (probably epidote)which fills fractures in the rock.Aplite dikelets also cut through the gneiss.These dikelets and veins provide markers to indicate offset during later deformation, which often is accompanied by metamorphism. Thus, on the rock surface we can distinguish several deforma-tional events during which minor movements along fractures have offset dikelets and veins.These fractures or faults have been healed by hydrothermal minerals and in turn are cross'cut by later dikes, veins and fractures. Features A and B are shown on the photographs and on the geologic map, Figure 2.See the key, Figure 3 for numbered features.Feature A has an average orientation of N34'E, and 75 SE.Strike separation on this'feature is right lateral.The two features which have been offset by Feature A are a NW-trending granitic dikelet (No.2)and a%J-trending fracture (No.9)which is filled with a green mineral (probably epidote).The granitic dikelet and the epidote-filled fracture show separations of 6 and 3 inches respectively. Mr.Harold R.Denton November 29, 1978 Feature A terminates within the core.trench.In addition, Feature A intersects another NW-trending epidote-filled fracture (No.10), but does not offset this fracture.Furthermore, there are at least two major NW-trending fractures parallel'to Feature A which do not displace the NW-trending epidote-filled fractures (No.9 and 10)or the granitic dikelet (No.2).It is concluded that the movement along Feature A was very old and of limited amount because: (1)Feature A terminates within the core trench, or has healed sufficiently to be unrecognized beyond a 60-foot length;(2)Feature A is cross cut by other fractures which , have not been offset.Feature B is a group of four en echelon fractures that strike approximately ease-west and show 1.0 to 3.8 inches of right lateral separation. The offset distance of the granitic dikelet along the en echelon fracture is exaggerated by the exfoliated surface.The feature that has been offset is the same granitic dikelet (No.2)which was displaced by Feature A.Evidence indicating that move-ment along these en echelon fractures is very old and of small distance is that all four of the en echelon fractures have been completely healed or are terminated one to.ten feet from the granitic dikelet.Important additional evidence for the age of Features A and B is that these features and younger fractures show healing.The healing process would have occurred during the period of deformation-mineralization which happened over 225 million years ago.Based on the geologic history of the area, relationships of the faults and fractures as described and on the evidence of healing by hydrothermal mineralization, Features A and B cannot be described as"capable faults" as that term is defined in Appendix A to lOCFR100.Therefore, these features pose no problems for the integrity or safety of the Shearon Harris Nuclear Power Plant Main Dam. Mr.Harold R.Denton November 29, 1978 Carolina Power&Light Company indicated to your staff that the main dam construction could be impacted if the geologic anomalies are not resolved by December 10, 1978.Your staff has indicated that they would like to make a site visit to view these f'eatures and that the earliest that they could come was sometime during the week of December 4, 1978.We request that your staff members visit the site as early'as possible in order to to minimize any NRC impact on construction.

Dear Mr.Denton:

Carolina Power&Light Company (CP&L)reported the existence of a ,geologic anomaly located in the main dam core trench between Stations 2+90 and 3+90 on November 9, 1978.This anomaly was identified as Fault'A.On November 16, 1978, CP&L reported two separate geologic anomalies located in the main dam core trench between Stations 2+90 and 3+90.These anomalies were identified as Fault Group B and Fault C.On November 29, 1978, CP&L submitted a report discussing Fault A and Fault Group B and committed to provide a report on Fault C upon completion of a geologic investigation. On December 1, 1978, CP&L reported the existence of another geologic feature, Fault Group D, in the main dam core trench between Stations 2+90 and 3+90.ring the NRC personnel site visit on December 8, 1978, Mr.Tom Cardone,'taff geologist, was given the opportunity to view these faults.Also ing the December 8, 1978, NRC site visit, Fault A2 was identified in the main dam core trench.On January 19, 1979, CP&L reported the existence of Fault A3 located in the main dam core trench southeast (downstream) wall.Fault A3 was originally thought to be an extension of Fault C, which had.previously been reported on November 16, 1978, until the geologic investiga-tion revealed it was a separate geologic feature.This report discusses the.final'valuation of Fault C, Fault Group D, and Fault A3.The status of the Fault A2 geologic investigation presently underway is described, and a final report will be submitted upon completion of the investigation. In order to more clearly identify the geologic features which we are reporting, we have refined fault nomenclature for this and subsequent reports in order to classify fault:s of similar orientation and sense of slip under the same letter designation (e.g., Fault Set"A"), with subscripts being used to distinguish faults within the fault sets (e.g., Faults A, A2, A3, etc).Within a set, closely spaced faults of similar orientation, sense of slip and origin are labeled as a group.Thus we had previously described"Fault Group B" in our report of November 29, 1978.A geometric classification approach was described to Mr.Tom Cardone, NRC staff geologist, during the inspection of December 8, 1978.411 Fayettevilte Street~P, Q.Box 1551~Raleigh.N.C.27602 Mr.Harold R.Denton January , 1979 In this report two other faults of similar orientation to Fault A have been labeled as A2 and A3.Fault A2, which was shown to Mr.Cardone during his inspection on December 8, 1978, will be described in more detail in a subsequent report since it extends into the upper, unexposed portion of the core trench.Fault A3 on the downstream wall of the trench was initially thought to be an extension of Fault C before the wall of the trench was ade-quately exposed.Figure 1 shows the location of the core trench where the faults occur.Figure 2 of this report, previously sent to you as"Main Dam Plan Geologic Map of Core Trench Sta 2+90 to 3+90" and the key Figure 3 have been revised herein to identify Fault Group D, Fault C, and Fault A2.Figure 2A is a map of the south-eastern wall of the trench which shows Fault A3.Table 1 shows the status to date on reporting of foundation features and faults at the main dam.Fault C Fault C, has an average strike of N20 E, dips steeply to.the southeast and terpinates within the core trench (No.27 and 58)as shown on the geologic plans, Figure 2 and 2A and as described on Figure 3.The fault bifurcates into two planes with similar orientations at several locations as shown on the plan view map and Photo 1.'ault C displaces three epidote veins (No.21 and 25)as shown on Photo 1.The strike separation of these veins ranges from nine inches to less than one inch (No.24, 26, 46).As can be observed from Figure 2, the amount of separation is decreasing to the northeast'ndicating that the fault is.dying out in this direction as shown on Figure 2A.Fault C terminates at fracture zone No.17.Another fracture with a similar orientation to Fault C begins on the south side of fracture zone No.17, but it does not offset an aplite dikelet (No.48)nearby and it also terminates locally (No.49).Fault C is also cross cut by two NE trending fractures and one NW trending fracture with no offset.An orange-red coloring along, the trace of Fault C and a 1 to 2 mm wide, milky-white layer within the fault plane suggest that Fault C has been filled, with hydrothermal minerals during late stage thermal activity.Fault Grou D Fault Group D is composed of four closely spaced fault planes which offset a small pegmatite dike at the main dam centerline near station 3+32.See Photo 2 and Figures'and 3.Maximum separation is 2.2 feet along a N40 W set of planes.True slip as indicated by slickensides is probably less than one foot.Lengths of the planes are less than six feet.A pod of massive biotite which is not offset has been deposited across the fault planes.Fault A2 Fault A2 as shown on Photo 3 and Figure 2 has an orientation of N34'E, 81'SE.This fault shows right lateral strike separation of one to four inches (No.38, 39, 40).Fault A2 is located en echelon right to Fault A and is filled in places.amount of the fault traced as with a black mineral very similar to that noted for Fault A.The strike separation along Fault A2 is decreasing to the northeast where terminates at station 3+02.To the southwest Fault A2 has yet to be cleaning has not progressed above station 2+90.Fault A3 I Fault A3 is located in the southeast wall of the core trench and has an orientation of N40'E,'82'SE.(See Photo 4.)This fault offsets the same epidote vein (No.9)as does Fault A.Fault A3 shows four inches of right lateral strike separation. The fault terminates to the northeast near station 3+47 and cannot be traced more than one foot beyond the offset to the southwest. If the plane of Fault A3 were projected-to the southwest for several feet, it would cross a quartz-feldspar-biotite vein and an aplite dike.Neither of these markers were found to be offset by any of the northeast-southwest trending fractures in the southern wall of the core trench.Fault C, Fault Group D, and Fault A3 show small displacements (all probably less than o'e foot);cannot be traced beyond the core trench;and either contain minerals that were probably deposited during ancie'nt thermal activity or,.when the fault alignments are projected a few feet, they encounter veins with, hydrothermal minerals which have not been displaced. Thus, like Fault A and Fault Group B, of the November 29, 1978, report, the small displacements, short lengths and mineralization along the fault planes indicate that these three faults developed prior to ancient thermal activity.Attachment B of the CP6L report of October 17, 1978, to the NRC on"Geological Feature at the West Wall of Main Dam Diversion Conduit" documented that the last deformation-mineralization rocesses would have occurred over 225 million years ago.This logic demonstrates t Fault C, Fault Group D, and Fault A3 cannot be capable faults as that term defined in Appendix A to 10CFR100.Fault A2 will be further described in a future report although it is similar to Fault A and almost certainly not capable as defined by 10CFR100, Appendix A.Yours very truly, M.A.McDuffie Senior Vice President Engineering 6 Construction RGB/mf Attachment cc: Mr.James P.O'Reilly TABLE 1 MAIN DAM FOUNDATION FEATURES AND FAULTS DISCOVERED TO DATE Feature/Fault Deformational Feature Location Spillway Sta 15+41 Report to NRC Initial Written 12/8/77 12/15/77 NRC 12/14/77 Schistose'Zone Fault A Conduit Sta 2+55 Core Trench Sta 3+10 9/19/78 10/17/78 11/9/78 11/29/78 9/19/78 12/8/78 Fault Group B Core Trench Sta 3+10 11/16/78 11/29/78 12/8/78 Fault C Fault Group D 1t A2 Fault A3 Core Trench Sta 3+60 Core Trench Sta 3+32 Core Trench Sta 3+00 Core Trench Wall Sta 3+40 ll/16/78 12/1/78 12/8/78 1/19/79'l/16/78 This Report ThiS Report Pending This Report 12/8/78 12/8/78 12/8/78 12/8/78 Offsets in Spillway Spillway Sta 11+70 Sta 12+02 Sta 12+10 12/20/78 Pending Pending 8 N 690,000 o o ei ttt CO o ri Itl CHANNEL AIIXII.IAR P SEPARATING DIKE%AUXILIARY DAM N 684 000 EMERGENCY SERVICE WATER ISCHARGE CHANN L.:,:,,II,.;.s p g CODLING TOWER p g MAKE-UP WATER":::P4947,:,::::;::. g INTAKE CHANNEL, AUXILIARY DAM SPILLWA Y EMERGENCY SERVICE WATER IN TAKE CHANNEL N 678,000 O V~sV~5 672,000'l'l/err(I'ear~r Of'$ttrtl rpG rip/f'r'gl~MAIN DAM-A DIVERSION CONDOIIS MAIN DAM SPILLWA Y N 660,000 (EtOt f0 SCSId I CAROLINA POWER 8c UGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT EBASCO SERVICES INCORPORATE D LOCATlON MAP FIGURE 1 'a~'RO'""'PERTURE CARD EXPEANA TION 0100 0105 0+ID 0115+eh MatcM~for F re 28:UL:.H:rr'Sr':,.:IN::r ~11:0:::.:.9" A.::::.-:::IU.,H.::I:.VSI r.n::.01".,:r."...:: I::.::.':::A::::.U:.::"..--".Ahhtgh-.urn h:::<<p..C.PAV..h...Err...h Yhh: n:.r..: Ch 8 eh MO-.hh;V.'g:,'::,:::hg'.::,."hhh.':::;::.I 1::;':::::::::: h'SHMO PS".:::-::: 'cr::: 'rh'Cr::g:::.'r:::.: L3 Qe~~E3 Igg i@i/<~p'oliar<<l Gnnire Schi Note Gr<<rire Mhha Schnr Homhfende Mica Gnsin p<<hfr wfgh rrfarirt lateral mox<<rhenr shown hwdr snows<<Nr dth Ol tnt fault pr<<M.Exloliarian unarhering orrface HFYO lMChurrs pointing roun rht Rrriace.Compo<<Jonal fayeribg, h<<hunn down dip.Vrfn dikelrr.or minerarir<<l franur&Jcinr or conan.Srri ke and dip ol ComprnhMxnf farering-So Srnke<<xldipolJoinrt Sr Srrike and dip of Mer<<norphi& loliarionin graniret-Sf Strike<<xf dip of Gdnr frfiadon in Gr<<rire-$2 Ver Jcaf f'orih L Bearing and plunge of finesrkxs SHMO-PI Sunple Eocadon 0 9 10..I OI30)4 Ip Otg hu I3 Oi40-I I.'-"'~h:::::v ':::.':':: ": '.::;.:::'~II-I"..I:'Ac Mathth Une for Figure 2*'I-I I SOurhtatr Well OfCOrt Trtnrh 1 r r AIOTEI SEE FIGURE 3 FOR KEY TOGEOLOGICSECTION I xU sr~I SnU~e.~r~No.DATII JIEYIQoN&Y Esk ahFFROYED SCALE IN FEET CAROUNA tOWER&UCHT SHEARON HARRIS NUCLEAR POWER PLANT MAIN DAM PLAN GEDI.OGIC MAP SOUTHEAST SIDE OF CORE TRENCH STA.2e90 to 3F90 EBASCO SERVICES INCORPORATED SCALE I~9'rl rt IS Also Available Ou Aperture Card FIGURE 2'HIS DOCUMENT IS DELIVERED IN ACCORDANCE WITH AND tt SIIIMECT TO THE tROVISIONS OF SECTION X Ot THE CONTRACT SETWEEN CARO..UNA FOWER&LIGHT COMFANY ANO ESASCO SERVICES INCORFORATED DATED SttTEMSER I, 191&.AS AMENDED.0 830064:0 M 4I'1 C >P RC'.APERTURE 'ARD 0+25 CO C4+0+25 N63E 0+30 0+35 66:,-~>>,,~4ne fP 75 65.:..'-"'.....:~c,.~ .~.~.~~".-.,.~.-'.'.,"..SP:.'.:':":- '::.'.'.'6P

Attached is a report on a micaceous gneiss layer and a schistose zone that was requested from Carolina Power&Light Company by Mr.Tom Cardone, NRC Staff Geologist, during his inspection of the main dam core trench on December 8, 1978.As indicated in the report, the evidence demonstrates that the micaceous gneiss layer and schistose zone in question originated about the same time as the nearby schistose zones at the main dam conduit wall.We have previously documented that the latest deformation-mineralization pro-~~~~~cesses for these zones occurred over 225 million years ago.Therefore, CP&L concludes that this particular micaceous gneiss layer and schistose zone cannot be capable faults as defined in Appendix A to 10CFR100.Yours very truly, QK 7w E~M.A.McDuffie Senior Vice President Engineering &Construction JJS/mf Attachment cc: Mr.J.C.Bryant 411 FayeueVille Stieel~P.O.BOX 1551~Raleigh.N, C.27C>02 I;H:1!i f:tl Sl:IlVICI:S IiCOIIFOhhT)D January 23, 1979 SHEARON HARRIS NUCLEAR POWER PLANT UNITS NOS.1, 2, 3 AND 4 GEOLOGIC REPORT ON GNEISS LAYER 63 AND SCHISTOSE ZONE 82 AT MAIN DAM The following is a report on a micaeous gneiss layer (designated 63)and a schistose zone (designated 82), requested from CP&L by Mr.Tom Cardone, NRC Staff Geologist, during his inspection of the Main Dam core trench on December 8, 1978.To determine the nature of these two features, the northwest side of the core trench, from Sta.3+60 to 2+90, and the northwest wall of the trench, from Sta 3+15 to 2+90, were mapped at a scale of 1 inch 5 feet.The area where Schistose Zone 82 passes under the conduit below Sta 3+60 had been mapped earlier at 1 inch 10 feet.The following is a description of the two features as documented by the geologic plan D 0 southeast side of the trench (Figure 2), the geologic plan of the northwest si of the trench (Figure 2B, the geologic section (Figure 2C), where Zone 82 passes into the wall, the key (Figure 3)and photo 1..4 Micaeous Gneiss La er 63 Excavation of the softer rock has created a'epression along the gneiss layer from above core-trench Sta 2+90 to Sta 3+32 where the micaeous gneiss grades into the country rock (See Figure 2B and Photo 1).Additional areas of the gneiss beyond Sta 2+90 will be exposed as the upper part of the trench is cleaned.The gneiss is 3 to 12 inches wide, strikes almost parallel to the trench, and dips toward the northwest wall of the trench.At both contacts the micaeous gneiss grades 'into the surrounding, harder, fine-grained, hornblende-mica gneiss.'oliation in the micaeous gneiss layer is concordant across the lithologic contact with the hornblende-mica gneiss;the contacts are sinuous rather than planar.The concordant foliation and sinuous contacts show that the contacts are not faults.However, even if we assume that faulting occurred, the movement.must have taken place along a plane or group'o'f planes roughly parallel to the plane of foliation of the hornblende-mica gneiss country rock and is very ancient, as shown by the following: 1.Four northeast-trending fractures (76 6 77 cross the micaeous gneiss layer between Stations 3+00 and 3+05 without offset.2.The segment of Fracture Zone 17, striking N80 M, crosses the micaeous gneiss layer without offset.The relative age of Practure Zone 17 is known from its relationship to Fault Group D, in that, the fault group is part of the N40 W-segment'of the Fracture 17 conjugate pair.(See Figure 2 and Item 17 in key, Figure 3.)Fault Group D is'post-dated by a large biotite pod (41), a product of late Paleozoic hydrothermal 'activity, as out1ined in an earlier report.Therefoie, the micaeous gneiss layer at 66 is older than the fracture zone, which is, older than the biotite pod.Schistose Zone 82 The schistose zone is exposed in the core trench, in a second depression extending passes into the trench wall at Station 3+10 (See Figures 2B, 2C and Photo 1).Th e is composed of a blackish-green mica schist, a gradational lithology between the fine-grained hornblende-mica gpeiss along the south contact and the strongly foliated, quartz-feldspathic gneiss with thin schistose layers along the north contact.~Large quartz pods (60)are common within the mica schist.They have been folded and contain little or no feldspar, indicating that the pods represent a different and older generation of quartz than that associated with feldspar and biotite in the northeast trending veins and gashes (81).The following lines of evidence indicate that the mica-schist schistose zone resulted from deformation, rather than faulting, which occurred during Late Paleozoic regional tectonic events;1.ere is no mesoscopic evidence for brittle failure in the gneissic rock.oth the hornblende-mica gneiss and the quartz-feldspathic gneiss show strong foliation from regional metamorphism. There are no distortions of schistosity in the schistose zone that are related to brittle deformation along either contact.2.The mica schist schistose zone represents a gradational lithology between the surrounding fine-grained hornblende-mica gneiss and the quartz-feldspathic gneiss.3.The schistose zone is folded with the surrounding country rock.4.The contacts of the schistose zone are sinuous, not planar. However, despite this evidence, if we assume that faulting occurred, it was'I very ancient, based on'the following: ~)1.Fiactures (78,6 80)and a gash filled with quartz and feldspar (81)cross the south contact of the zone, without offset.2.While veins, pods, or lithologic units do not completely cross the schistose'zone, neither are they truncated at the contacts.The above evidence demonstrates that Micaeous Gneiss Layer 63 and Schistose Zone 82 originated about the same time as the nearby schistose zones at the conduit wall, for which we documented that the latest deformation-mineralization processes occurred over 225 million years ago.Please see previous reports to the NRC,"Geological Feature at the West Wall of Main Dam Diversion October 17, 1978, and January 19, 1979.Thus, we conclude Conduit", dated that Micaeous Gneiss Layer 63 and Schistose Zone 82 cannot be capable faults as that term is defined in Appendix A to'10 CFR 100.

Dear Mr.Denton:

The attached report provides a final geologic description of Faults A2, A4, A5, E, F, F2, and Fault Group G located in the Shearon Harris Nuclear Power Plant's (SHNPP)main dam core trench between Stations 1~90 and 2+90.Tne existence of these geologic features has been previously reoorted to your stafr by either telephone or discussions with your staff representa-tives during site visits.As discussed in the report, these geologic features occurred prior the deformation-mineralization process of 225 million years, ago.Therefore, olina Power&Light Company concludes that these geologic features cannot be capable faults as defined in Appendix A to 10CFR100.Yours very truly, M.A.McDuffie Senior Vice President Engineering 6 Construction RGB/mf Attachment cc: Mr.J.C.Bryant bcc: D.L.Bensinger R.E.Jones S.McManus f~Q"~g A~~,~t~,~~1~ SHEARON HARRIS NUCLEAR POMER PLANT UNIT NO.S 1, 2, 3, and 4-GEOLOGIC REPORT ON FAULTS A2~A4, A5, E, F, F2%and G AT THE MAIN DAM The following is a report on small Faults A2, A4, A5, E, F, F2, and G which are all exposed in the core trench between Stations 2+90 and'1+90.'ocation of the core trench is shown on Figure 1.These seven faults are shown on the geologic map, Figure 2, at a scale of 1 inch to 10 feet.Als'o see Photo 1.Numbered features are described on the key, Figure 2A.Faults A4, E, F, and G were first shown to NRC geologists on January 30, 1979.Fault A2 was inspected in December and Fault F2 and A5 were found after the January 30th inspection. Table 1"Foundation Features and Faults Discovered to Date" has been revised to show the current status of fault reports for the main dam.FAULT A2 Fault A was first described in our report of January 29, 1979 as follows: "Fault 2 as shown on Photo 3 and Figure 2 has an orientation of N 34 E 81 SE.(his fault shows right-lateral strike separation of one to four inches (No.38, 39, 40).Fault A2 is located en echelon right to Fault A and is filled in places with a black mineral(s) very similar to that noted Fault A.The amount of strike separation along Fault A2 is decreasing he northeast where the fault terminates at Station 3+02.To the south-Fault A2 has yet to be traced as cleaning has not progressed above Station 2+90".Fault A2 has now been exposed to where it terminates in the southeast wall at Station 2+70.The additional exposure supports the previous evidence for the noncapability of the fault.FAULT A4 Fault A4 has a strike of N39 E, a vertical dip, and shows a maximum of 1.25 inches of right-lateral strike separation of a small quartz feldspar veinlet (No.32).The fault extends for approximately 4 feet fxom Station 2+89 to 2+85 22 feet downstream of the centerline. Fault A4 is located en enchelon right to Fault A and A2 and has iron stains and mineralization in the fault plane as do Faults A and A2'.A small epidote vein, too small to show on the map, crosses Fault A4 near Station 2+85 with no offset.FAULT A5 Fault A5 has an orientation of N51E 85 SE and shows 4.5 to 5 inches of right-lateral strike separation of two small pegmatite veins (No.27 and 28).Fault A5 extends from Station 2+20 to 2+40 about six feet downstream from the centerline. Near Station 2+23 the pegmatite vein has been smeared along the fault plane.At Station 2+34 Fault A5 passes through a small pegmatite"vein with no offset.To the southwest, near Station 2+20, Fault Ad terzdnates at a metamorphosed mafic dike which is older than Fault A.In places, the fault is filled with e thin layer of brownish-'lack neralization. FAULT E Fault E has an orientation of N42 E 80 SE and shows 1.25 to 0.5 inches of left-lateral strike separation of two small pegmatite veins (No.33 and 34).'Fault E extends from Station 2+53 to 2+42 and is about 20 feet downstream from the.centerline. Iron stains and a thin layer of fine-grained black minerali-zation occur in the fault.The nature of this mineralization and the orientation of Fault E are very similar to the A-type faults previously des-cribed, except that the sense of separation is left lateral for Fault E.This fault crosses a third pegmatite vein at Station 2+43 with no offset.FAULT F Fault F has an orientation of N64 E 77 NW, extends from Station 2+ll to beyond 1+90 and is about 22 feet downstream from the centerline. The fault is not open and appears to be partially healed as it passes beyond Station'1+90.Maximum displacement is 2.5 inches of left-lateral strike separation. Two small pegmatite veins (Nos.4 and 6)and two epidote veinlets (Nos.2 and 8)are.offset between Station 1+95 and 2+05.However, the amount of strike separation is decreasing in both directions along Fault F.An epidote veinlet (No.9)and a quartz veinlet (No.7)cross Fault F with.no offset.Therefore, Fault F is definitely older.than the quartz mineralization and some of the epidote mineralization. FAULT F2 Fault F is oriented'N64 E 80 NW and extends from Station 1+97 to 2+20'2 about 7 feet upstream from the centerline. This fault has 6.5 inches of apparent left-lateral strike separation of a fine-grained mafic vein (No.16).Some of the observed separation may not be real as the vein width varies from 1 to 4 inches.Two thin vertically dipping pegmatite veinlets cross Fault F2 with no offset.The absence of any offset of these vertically dipping peg-matite veinlets also suggests that the amount of true separation is considerably less than 6.5 inches.The fault terminates at Station 1+97 to the southwest and at a metamorphosed mafic dike near Station 2+20 to the northeast. n FAULT GROUP G Fault Group G consists of two closely spaced subparallel fractures with orientations of N60 E 85 NW and N61 E 81 NW.The group extends from Station 2+06 to beyond Station 1+90 and is located about 8 feet downstream from the centerline. Fault Group G shows 1.5 to 3.5 inches of right-lateral strike separation of a pegmatite veinlet which has an orientation of N65 W 70 SW (Nos.14 and 15)and 16.5 inches of left-lateral strike separation of.a 4-inch wide pegmatite-vein which has a very shallow dip to the northeast. ometry of the two pegmatite veins and the N61 E 81 NW fracture of Group G shows that there has been normal movement along this fracture with the'orthwest block having moved down 6 inches relative to the southeast block.The N60oE, 85 NW fracture of Fault Group G does not offset the shallow-dipping pegmatite vein near Station 1+88 and is also partially healed beyond Station 1+90.The N61 E 81 NW fracture of Fault Group G has been filled with biotite and opaque minerals to a thickness ranging up to 2 to 3'nches near Station 2+05.A thin epidote veinlet crosses the N61 E 81 NW fracture of Fault Group G at Station 2+02 with no offset.Fault Group G will be further exposed when cleaning proceeds beyond Station 1+90 in the core trench.CONCLUSION The small separation along these faults, the short lengths of the faults, the relationship of veins and pods crossing the faults, and/or the relation-ship of the faults to two metamorphosed mafic dikes as well as mineralization in the faults indicate that Faults A2, A4, A5, E, F, F2, and G developed prior to ancient thermal activity.Attachment B of the CP&L report of October 17, 1978, to the NRC on"Geological Feature at the West Wall of Main Dam Diversion Conduit" documented that the last deformation mineralization process would have occured more than 225 million years ago.Because the small movement along these seven faults occurred prior to the deformation-minerali- ~zation, Faults A2, A4, Az, E, F, F2, and G cannot be capable faults as that 4 is defined in Appen8ix A to 10 CFR 100.

Dear Mr.Denton:

I The attached report provides a final geologic description of Fault F3 located in the west wall of the Main Dam Diversion Conduit at Station 5+48, and a schist layer at the main dam core trench Station 11+52.The schist layer was preliminarily reported as a"fault" pending additional study.The existence of these geologic features has been previously reported to your staff by telephone and by discussions with your staff representatives during site visits.4 As discussed in the report, these geologic features occurred prior to the deformation-mineralization process of 225 million years ago.Therefore, Carolina Po r&Light Company concludes that these geologic features cannot be capable as defined in Appendix A to 10CFR100.Yours very truly, M.A.McDuffie Senior Vice President Engineering and Construction SDF/tl cc: Mr.James P.O'Reilly SHEARON HARRIS NUCLEAR POWER PLANT UNITS 1, 2, 3 and 4 GEOLOGIC REPORT ON FAULT F3, AND SCHIST LAYER AT CORE TRENCH STA ll+52 The following is a report on small Fault F3 exposed in the west wall of the" Main Dam Diversion Conduit at Station 5+48 and of a schist layer at core trench Station ll+'52.Fault F3 was reported to the NRC on April 9, 1979;the schist layer, on Apri'1 18, 1979, as a"fault"', pending additional study and submission of the present report.Mr.Jack Harris, NRC Geologist, has inspected both features.Table 1,"Foundation Features and Faults Discovered to Date".has been revised to show the status of investigations as of May 29, 1979.Figure 1 shows the location of the conduit and core trench.FAULT F3 F ault F3 is shown on Figure 2, Plan Geologic Map and West Wall Section of Diversion Conduit and in Photo 1.It is oriented N44E 82 NW to 88o SE and shows 5 inches of apparent normal dip-slip separation of a 5-inch-wide aplite vein, as shown at No.4 on the west wall (Figure 2).The fault was tiaced into the Diversion Conduit invert (Plan View), where it crosses, with no offset, two east-west trending joints (No.16)and a northwest-trending fracture zone and schist layer (No.18).Fault F3 terminates in the invert at a northwest-trending joint (No.20)one foot north of the Diversion Conduit centerline at Station 5+50.us, Fault F3 does not offset and is older than the several fractures, joints, and a schist layer'it crosses.The schist layer at No.18 must predate the last deformation-mineralization event, documented to have occurred more than 225 million years ago, in Attachment B of the CP&L report of October 17-, 1978, to the NRC on"Geological Feature at the West Wall of Main Dam Diversion Conduit." Therefore, Fault F3" cannot be a capable fault as defined in Appendix A to 10 CFR 100.SCHIST L'AYER AT CORE TRENCH STA ll+52 During mapping of the core trench on the left (east)abutment of the Main Dam (Figure 1),.an apparent offset of two quartz veins along a gently dipping, 1 to 2-inch-thick schist layer was noted.This apparent offset (Photo 2), located approximately at Station 11+52, 17.5 ft.upstream from the centerline, affects two quartz veins.At the schist layer (Figure 3, No.1), one is 5 inches wide (No.2)and the other, 14 inches wide (No.3).This feature has now been studied in detail.This document reports on the results of this study.~A few feet northeast of the quartz veins, this schist layer is cut by a small body of what appears to be granitic pegmatite (No.10);there is some suggestion that the pegmatite cuts the hinge of a recumbent isoclinal fold.To the south-west, as shown on Figure 3, the single schist layer divides into two thin layers, each 1/4 to 1 inch thick.Both of these layers thicken to the southwest and are folded into subhorizontal isoclinal folds. The closure of the uppermost of the two layers is'hown on Figure 3 in the area of Station ll+31, 26 feet upstream from centerline. The closure of the other layer is almost 50 ft.to the southwest and is not shown on the ma1 A number of schist layers, including Number 5 on Figure 3, have been obseviPed. They are complexly folded, foliation generally paralleling the layering.The layers are thickest in the hinge of the folds and thin greatly in the limbs.Only a few quartz veins cross these schist layers, however;joints in the granite may cut across the entire layer with n'o offset (No.6), may die out within the schist, or may stop at the contact within the schist.The schist layers exposed in the left abutment, including the one reported as a possible fault, are similar to those discussed in the CP&L report to the NRC of October 17, 1978,"Geological Feature at the West Wall of Main Dam Diversion Conduit".The fact that the foliation is parallel to the boundaries of the schist, even within the noses of the folds, shows that the schist layers are ,actually the limbs of an earlier generation of isoclinal folds.These limbs;then, have been refolded by a later generation of isoclinal folds, such as the one which closes in the area of Station 11+31, 26 ft.upstream of centerline. Since these schist layers are commonly cut by joints which are not offset, and since other quartz veins do not cross these schist layers, it is likely'that quartz veins 2 and 3 (Figure 3)are completely separate features and not the same vein which has been offset by a fault.During the repeated episodes of folding affecting these rocks, the relatively ductile schist layers, including the one reported as a possible fault, undoubtedly experienced more internal ductile flow and movement than the far more rigid granites.This ductile flowage of schist is a typical response to deep-seated deformation conditions and is in no way similar to shallow-seated brittle failure which is characteristic of faulting.There also is evidence demonstrating that this feature is very old.As shown by the dip and strike symbols on Figure 3, the schist layer and foliation are folded into a very broad, open anticline plunging gently to the west.The amplitude of this fold is less than 1 foot, and consequently the fold is visible on the map, except for the change in dip, and strike of the foliation as shown in the area just south of quartz veins Nos.2 and 3.The granitic pegmatite cuts the schist zone only a few feet from quartz veins 2 and 3.Finally, three small joints (No.7, 8, and 9), all cross one contact of the schist layer without any offset, although all die out within the layer.Photo 3 shows one of these small joipts in the granite that die out within the schist (No.8).In conclusion, as discussed in the, above-mentioned report of October 17, 1978, the last folding and mineralization are older than 225 million years.The evidence shows that the feature is a folded compositional layer and suggests that quartz veins 2 and 3 were never one and the same.The feature is thus not a fault.Even if it were a fault, it is cut by a granitic pegmatite or vein at least 225 million years old, as well as by joints.The feature is thus not a capable fault as defined in 10 CFR 100, Appendix A.

Close inspection of the dike and fracture indicates that the dike is not offset, but rather irreg>>)arly s1>a~><<1<.hro<>ghout i ts exposed length with a sudoen thickening at the location where i t is crossed by the joint.FAULT F4 AT STATION ll+90.'this f<at>>re h.s been classified with the"F" group of faults, which were 1>rovio>>sly exposed and investigated in the.'lain Dam core trench, because of>> i,t.s simi]ar orientation and sense of apparent movement.Fault F~is 102 feet east of the spillway centerline. It strikes N60 E, dips 50 SE, and offsets a granitic dike which is one to thiee inches wide.As shown in Photo 3, there are six inches'f left lateral strike separation of the'ike along the fault.The fault plane is filled by a 1/8 inch thick vein containing quartz and lesser amounts of feldspar, mica and altered dark minera]s.The mineralization is readily plucked away when cleaned with an air hose and is not always visible.The fault terminates within four feet of the dike to the southwest, and is masked by a residual soil horizon to the northeast. CONCLUSIONS SpH]way Features 1 and 2 are not faults.The apparent offsets initially reported are created by the intersection of joints and suddenly widening granitic dikes Even if some movement had occurred along the joints at some sta<e, Spillway Features 1 and 2, and Fau]t Fq are not capab]e faults.Tne presence of minerali-ration a]ong the fau]t plane and in the joints indicates that these features developed prior to ancient thermal activity.The most recent deformation/minerali-lq zation occurred at least 225 million years ago as documented in Attachment B of the CP6L report of October 17, 1978, to the NRC on"Geological Feature at the h'est L~al]of the Main Dam Diversion Conduit".Thus Fault Fq and Spillway Features 1 and 2 cannot be capab]e faults as that term is defined in A, pendix A to 10 CFR]00.A]so, the short length of the fractures, the small separations involved, and the cross-cutt"ng re]ationship of a non-displaced quartz vein indic'ates that U~c se ientures are minor and ancient. t I>,.r I:<~I.<<C 1 C I;I:.I oit T ON FAULTS A6 CZ F5 G G2 03 II and 1 AT TIIF.IA I N I)'(A6, C2, F5, G, G2, G3, H and l)fo1lowing report describes small faults w>>i ch are exposed in the floor of the Hain Dam core trench between St:at ions 1-I 50 and 1+90~Figure 3 is a geologic map of the core trench showing the location of the eight faults at a'cale of one inch equals five feet.Numbers i>>thc t rxt refer eo the location o f features on this map.Foul t A6 Fa>>l t A6, whi ch trends N40 E and dips 70 SE, offsets an epi<lote vein (No.4)at.Stat'1 on 1~'89, 25 feet downst:ream of the dam centerline.

The fault is crossed without offset by an epidote vein"(No.11).The two fault traces terminate to the (See Photo 7.)southwest at Stations 1+66 Faults G2 and G3 Fniilts G2 and G3 consists of two subparallel fault planes which offset a 1/2 inch'wide granite pegmatite (No.6).'Itic displacement along G2 is located at Station 1+57, ll feet downstream of the dam centerline. The fault strikes N69 E, dips 75 SE, and is filled with quartz.There is one inch of right lateral strike separation of the pegmatite. Thc G2 fault plane terminates 20 feet southwest~here it intersects the core tr~nch wall and dies out 13 rect northeast of the displacement. It is crossed by fault I as we33 as by several joints (Nos.7 and 9)which how no offset.The displacement along G>is located at Station 1+57, 10.5 feet downstream of~~II dam centerline. There is 1 1/4 inches of right lateral disp3acement of"the granite pegmatite (No.6).The fault.plane strikes N65 E, and dips 81 SE The fault dies out in a short distance in both directions from the offset for 5 a total length of 3.5 ft.It is crossed without offset by Fault I.(See Photo 8.)Fault H Fau3t li strikes N58 and is nearly vertical.At approximately Station l.l.85, 0 5 feet downstream of the centerline, there are 2 inches of right 3ateral strike..epnrntion of a 3 inch wide aplite dike (No.12)and at Station 1+84, 3 feet\downstream of the centerline, there are 2.5 inches of right lateral separation of a 3 inch wide aplite dike (No.13).Northwest of station 1+84, the fault is fi13ed with epidote (No.15).t z-f i 33 ed f'rac t ure (No.14).The fault is crossed without offset by a (See Photo 9.)Fa>>3't I F'a>>3t 3, whicli strikes N57 l4 and dips 82 NE, offsets a granitic'egmatite (No.6)<<t"tation 1+58, 10 feet downstream of the dam centerline. There is one foot of left lateral strike separation of the pegmatite which was also ol'Cset by Fa>>3ts G and Gg Fault I does not offset G2 and G and is 3'illed with epidote.To the southeast, Fault I continues into the wall of the core trench and to the northwest it dies out at Station 1+47.(See Photo 8.)Conc1>>sions The ia>>its described above cannot be considered capable faults because the"t movement took place prior to the most recent mineralizing event.The faults involve very small amounts of displacement (14 inches or less)~).All of the faults are crossed,.undisturbed by either aplite dikes, epidote veins, quartz veins or other fractures. Faults G2, H, and I are minerals.zed. As documented Attachment B of the CPSL report of October 17, 1978, to the NRC entit3ed"Geological Feature at the blest Mal,l of the Main Dam Diversion Conduit," the most recent deformation/mineralization event occurred at least 225 million years ago.Thus, these faults formed prior to 225 million years ago and cannot be considered capable faults as the term is defined in Appendix A to 10 CFR 100.

SHEARON HARRIS NUCLEAR POWER PLANT UNITS 1, 2, 3, and 4 GEOLOGIC REPORT ON FAULTS J1 and J2 The following is.a report on small Faults Jl,and J2 exposed on'the floor of the Main Dam Spillway between Stations 14+47 and 14+57.These faults were reported to the NRC on October 7, 1980 and Mr.Jack Harris, NRC Geologist, inspected both features on October 9,.1980.Table 1,"Foundation Features and Faults Discovered to Date" has been revised to show the status of investigations as of October 16, 1980.Figure 1 shows the location of spillway and core trench.Fault J1 Fault J1"is shown on Figure 2 and in Photos 1, 2 and 3.It strikes N27 E and dips 81-82o NW.As shown in Photo 1 and 2, there is about one foot of right lateral strike separation of the two granitic veinlets along the fault.The fault plane is, in part, filled with quartz and other altered dark minerals and at Station 14+57, ll feet east of the centerline a 1/2 inch thick granitic veinlet crosses the fault trace without offset.Fault J2 Fault J2 is shown on Figure 2 and in Phbto 4.It strikes N24oE and dips 81 NW.Trace of the fault extends between Station 14+45 to 14+61.At Station 14+46, it displaces a granitic veinlet about lg inches with right-lateral sense of movement.It does not off-set a joint which crosses the fault, 12 feet east of the centerline at Station 14+48. Conclusions The faults described above cannot be considered capable faults.The presence of mineralization in the plane of Fault J1, and the cross-cutting relationship of the granitic veinlet indicate that the fault was formed*at least 225 million years ago,,as documented in Attachment.B of the CP&L report of October 17, 1978 to the NRC on"Geological Feature at the West Wall of the Main Dam Diversion Conduit".Fault J2 as crossed by a joint which has not been offset.Furthermore, Faults J1 and J2 both have small displacements and are very short.These facts all indicate that both faults are ancient and can not be considered capable faults as that term is defined by 10 CFR 100, Appendix A.
