\m,/
2.1 GENERAL DESCRIPTION Data are presented in this section as a basis for the selection of design criteria for the Oconee Nuclear Station, and to determine the adequacy of concepts for controlling routine and accidental release of radioactive effluents to the environment. A series of studies (geology, seismology, hydrology, meteorology, population and land use) have been conduccsd.
The site is located in Oconee County, South Carolina, approximately 8 miles northeast of Seneca, South Carolina. The area immediately north and west will be Duke Power Company's proposed Jake Keowee, and the Government's Hartwell Reservoir is south of the site.
Cooling water for Oconee will be drawn from and returned to Lake Keowce.
Limnological and thermal analyses of the lake have established that the Oconee site may be used for nuclear capacity of 3000 mwe and be fully com-patible with ecological and recreation aspects of the lake. These analyses have been approved by applicable State and Federal agencies, and Duke's license from the Federal Power Commission for the Keowee Development authorizes this use of cooling water for a 3000 mwe nuclear station at Oconee.
This Preliminary Safety Analysis Report covers Oconee Units 1 and 2 totaling
(-~)
1748 mwe, and no analysis has been included of the contemplated additional generating unit because the characteristics of that unit are unknown. When l
l Unit 3 should be proposed, Duke will file a separate application with support- l ing safety analysis.
The exclusion area around the site will have a radius of one mile. The boundary of the low population zone lies at a 6-mile radius around the site.
There are only six population centers within a 100 mile radius of the site.
Anderson, South Carolina, with a 1960 population of 41,316 is located 21 miles southeast of the site.
l The structures will be founded on normal Piedmont granite gneiss rock, and a I wealth of experience is available in designing and constructing heavy structures on similar foundations. The foundation materials present no special problems in design or construction. Foundations will be designed in accordance with the recommendations beginning on page 2A-10 of the report on Subsurface and Foundations Investigations attached as Appendix 2A.
2.2 SITE A"D ADJACENT AREAS 2.2.1 LOCATION The Oconee Nuclear Station site is located in eastern Oconee County, South Carolina, as shown in Figure 2-1, at latitude 34*-47'-39" N and longitude 82*-53'-57" W.
,< \
2.2.2 (v) LAND OWNERSHIP All property within a 1 mile radius of the nuclear station will be purchased c nn nnnn7 2-1 VV "UVU#

except for a small rural church plot, three small tracts of land, highway right-of-way and approximately 9.8 acres of United States of America Hartwell Project property. The Hartwell property is either a portion of the Hartwell Reservoir or subject to flooding and not suitable for other uses. The only connercial enterprises within the site boundary will be Duke's Keowee Hydro-electric Station and Oconee Nuclear Station. It is anticipated that three residences may remain in the outer portion (more than 1/2 mile) of the ex-clusion area. Arrangements will be made for the immediate evacuation of these areas in case of a major accident.
The 1 mile exclusion radius will form the site boundary which will be posted, and a fence will be erected around the immediate station area, as shown in Figure 2-2.
2.2.3 VICINITY North and west of the site will be the 18,400 acre Lake Keowee to be formed by Duke's Keowee and Little River Dams, as shown in Figure 2-3. Lake Jocassee, with a surface area of 7,600 acres, will be located approximately 11 miles north of the site. Hartwell Reservoir, a United States Government-owned lake, is located south of the site, and the Blue Ridge Mountains of the Appalachian chain lie northwest of the site.
Figure 2-4 shows the general geographical and topographical features within 50 miles of the site.
Oconee Nuclear Station is a part of Duke's Keowee-Toxaway Project combining hydroelectric, pumped-storage and nuclear power generation. Duke now owns approximately 150,000 acres of land for this project, including the 18,400 acres for Lake Keowee and 7600 acres for Lake Jocassee to the north. The bulk of Duke property outside these lakes lies in the sectors between NNW and NE from the Oconee Nuclear Station. This property is under forestry management and will also be used for controlled public hunting, fishing, camping, tourism and recreation in cooperation with State agencies and conservation groups.
2.2.4 RESIDENI POPULATION Figure 2-5 shows the population centers within a 100 mile radius of the site.
The largest city, Knoxville, Tennessee, located 97 miles northwest of the site, had a 1960 population of 111,827. The nearest population center, Anderson, South Carolina, is 21 miles southeast of the site and had a 1960 population of 41,316.
Figures 2-6, 2-7 and 2-8 provide a detailed analysis of population distribu-tion within a 50 mile radius of the site. Figure 2-6 shows the currently estimated (1965) and projected estimated (2010) population distribution in 16 directional sectors centered on the site and within 2, 3, 4 and 5 mile radii. Figures 2-7 and 2-8 show similar population distributions for 10 and 20 mile radii and for 30, 40 and 50 mile radii respectively.
The 1965 and 2010 projections are a linear extrapolation of the 1910-1960 long term trend. In the NNW and NE sectors within a 20 mile radius, the pro-jections have not been reduced to reflect population removed from the lake -
,g, 2-2
}(
(n) v sites and from other lands acquired by Duke since 1960.
These population projections indicate that the low population boundary can be selected at a distance of 6 miles from the site, and would include only about 3000 population by the year 2010, which satisfies the requirements of a low population zone.
2.2.5 PART-TIME POPUIATION It is expected that the proposed Lake Keowee and Lake Jocassee, along with Hartwell Reservoir will be the major features contributing to the part-time population within a 50 mile radius of the site. The recreational opportuni-ties offered by the lakes, such as boating and fishing, and the scenic beauty of the mountains will probably increase the population of the area during the summer months. Much of this temporary population will be on Duke-owned land and therefore subject to some planning and control.
2.2.6 LAND USE Figure 2-9 rhows the area of land in square miles that is pastured and culti-vated within a 50 mile radius of the site. The land use is shown in 16 directional sectors centered on the site and within 5, 10, 20, 30, 40 and 50 mile radii.
f-x The land use distribution was based on the 1964 United States Census of (v ) Agriculture Preliminary Report for Georgia, South Carolina and North Carolina.
Figure 2-10 shows the number of dairy animals, by counties, that will be grazing within a 50 mile radius of the site, except for four outlying counties (Hall, Greenwood, Swain and Buncombe). No figures are arallable at this time for these counties. The figures are from the 1966 census.
Figure 2-11 shows the location and distance from the site to reservoirs larger than 100 acres within a 50 mile radius. Each reservoir is numbered and tabulated on Figure 2-12, which lists the name and pertinent physical data, where available.
2.2.7 FUTURE POPULATION AND 1AND USE The future population for year 2010 is shown in Figures 2-6, 2-7 and 2-8.
Section 2.2.4 describes the population distribution and projections.
Except for Duke's encouragement of recreation on its Keowee-Toxaway Project la nds , there are no known future land use plans which have been developed for the area within a 50 mile radius of the site. However, portions of this area, particularly in the vicinity of Greenville and Spartanburg, South Carolina, have experienced substantial ind2strial growth over the past several years.
There is no reason to believe that this growth will not continue.

Duke's Visitors Center, recreation on the lakes, up to three residences and ,

2.3 METEOROLOGY The meteorological features of the site are favorable for a nuclear station.
Several modifications to the local climatology will occur as site development progresses. The initial clearing and leveling of land at the specific site location will produce an increase in drainage potential of light winds within the site boundary.
The addition of the large bodies of water will have two effects on meteorol-ogy. First, it will lessen ground frictional effects and tend to increase the wind speeds; most noticeably under light wind conditions. Second, the large bodies of water will increase the humidity by about ten per cent in the area and tend to decrease the frequency of Pasquill F and to increase the frequency of Pasquill E conditions.
Documentation of on-site meteorological parameters will demonstrate the valid-ity of the recommended diffusion model values tabulated below and shown in the complete Meteorology Report in Appendix 2B.
Values for Various Diffusion Models (The values are for use with the standard Gifford equation as in 14.2.2.3.6 of this report.)

2.4 HYDROLOGY AND GROUNDWATER 2.4.1 QIARACTERISTICS OF STREAMS IN VICINITY The major streams which drain the site are the Keowee River and the Little River.' These join near Newry, South Carolina, to form the Seneca River which is a major tributary to the Savannah River.
When Hartwell Reservoir was filled to elevation 660 in 1961, its backwater ex-tended up the entire length of the Seneca, up the Little River to the mill dam at Newry and up the Keowee to the vicinity of South Carolina Highway 183 bridge at Old Pickens.
When Lake Keowee is constructed, the main stems of both the Keowee and Little Rivers will be inundated to elevation 800, and the parallel lakes joined by a canal to form Lake Keowee.
Both the Keowee and Little Rivers are typical streams of the Piedmont Physi-ographic Province, having irregular courses with numerous right angle bends.
The gradients are moderate with few rapids and falls. In some areas the .
flood plain is well developed with wide, flat bottom lands on one or both I sides of the rivers.
l The following is a summary of recorded flow characteristics of the Keowee and Little River Basins:

An active quality-of-water data collection site is maintained at Gage 2-1850 near Jocassee, South Carolina. Water temperature is recorded continuously, and chemical analyses are made at infrequent intervals.
The present uses of the free flowing streams are relatively limited. The Oi Town of Seneca takes it raw water supply from the Little River and one of its minor tributaries. A part of the Town's treated sewage effluent is
_n n nn---
2-5 UU UUUOJ tt-'?
discharged into the same tributary at a point further downstream. Facilities are now being designed to permit the Town of Seneca to take its raw water l -
supply from Lake Keowee at a point 6 miles from Oconee Nuclear Station and to discharge its treated waste into another tributary to the Seneca River water-shed.
Several industrial plants, Clemson University, the Town of Clemson and the Town of Pendleton, South Carolina, take their raw water supplies from Hartwell Reservoir. The City of Anderson, South Carolina, is planning to take its future raw water requirements from Hartwell.
Lake Keowee, with an average volume of 810,000 acre-ft and an average dis-charge of 1100 cfs, will have an average retention time of 372 days. The effective retention time of cooling water effluent from Oconee Nuclear Station will be less because its point of discharge is oriented horizontally and vertically in proximity to the hydro station intake. Oconee's cooling water discharges about 3700 f t from the hydro station intake. A submerged weir with a crest at elevation 765, which is only 35 f t below full pond level, limits the hydro station water supply to the near-surface waters which include the warmed discharge from Oconee. The downstream Hartwell Reservoir has, at average pond level, a volume of 2,000,000 acre-ft, and average discharge of 4400 cfs, and an average retention time of 229 days.
Liquid effluent from Oconee's waste treatment facilities (Section 11) will be discharged to the tailrace of the Keowee Hydroelectric Station. Although not required by the design of Oconee, dilution can be increased by operation of the hydro units if necessary.
Agricultural use af the waters of the Keowee and Little Rivers as well as those of Hartwell Reservoir is very limited. Irrigation is not widely used in this area. Tributary streams are more often used for livestock watering than are the main stem rivers.
Sport fishing is done on all streams in this area. No commercial fishing is practiced except for small scale trapping of catfish and other rough fish varieties. Hartwell Reservoir is used for sport fishing and general re-creation as will be Lakes Keowee and Jocassee.
2.4.2 FLOOD STUDIES Since the proposed site of the Oconee Nuclear Station is located near the ridgeline between the Keowee and Little River valleys, or more than 100 ft above the maximum known flood in either valley, the records of past floods are not directly applicable to siting considerations.
In accordance with soun? engineering practice, records of past floods as well as meteorological records and statistical procedures have been applied in studies of floods through the proposed Keowee and Jocassee Reservoirs as !
a basis of spillway and freeboard design. l I

Statistical analyses have shown design reservoir inflows for both Lake Keowee and Lake Jocassee equal to respective design discharge capacities outlined above to have recurrence intervals less frequent than once in 10,000 ,
years.
The maximum wave height and wave run-up have been calculated for Lake Keowee and Iake Jocassee by the Sverdrup-limk formulae. The results of these cal-culations are as follows:

Studies were also made to evaluate effects on reservoirs and spillways of maximum hypothetical precipitation occurring over the entire respective drainage areas. This rainfall was estimated to be 26.6 inches within a 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> period. Unit hydrographs were prepared based on a distribution in time of the storms of October 4-6, 1964, for Jocassee and August 13-15, 1940, for Keowee. Results are summarized as follows:
Keowee Jo cas see 147,800 70,500 Maximum spillway discharge, cfs 808.0 1114.6 Maximum reservoir elevation 7.0 ft 10.4 ft Freeboard below top of dam While spillway capacities at Keowee and Jocassee have been designed to pass the design flood with no surcharge on full pond, the dams and other hydraulic structures have been designed with adequate freeboard and structural safety factors to safely accommodate the effects of maximum hypothetical precipita-tion. Because of the time-lag characteristics of the runoff hydrograph af ter a storm, it is not considered credible that the maximum reservoir elevation due to maximum hypothetical precipitation would occur simultaneously with winds causing maximum wave heights and run-ups.
The maximum Keowee tailwater level during hydro operation has been calculated to be elevation 672.0, which is 124 f t below the nuclear station yard eleva-tion (796.0).
Af ter construction of Lake Keowee, the maximum discharge due to hydro operation is expected to be 19,800 cfs. The minimum discharge with no units operating is expected to be 30 cfs.
In summary, the above results of flood studies show that Lakes Keowee and Jocassee are designed with adequate margins to contain and control floods which pose no risk to the nuclear site.
2.4.3 DESIGN OF PROPOSED KE0 WEE AND JOCASSEE DAMS Duke Power Company is preparing designs for these dams which are conservative and are based on sound Civil Engineering methods and criteria. The strength properties of f;undations and of materials that are being used in the design of the dams are based on values obtained from extensive field and laboratory tests. These designs will be reviewed by a board of consultants and reviewed and approved by the Federal Power Commission in accordance with the license issued by that agency. Keowee Dam will be designed to have an adequate factor of safety under the same conditions of seismic loading as are proposed in the design of the Oconee Nuclear Station. l The dams are being designed using the circular arc (and wedge at Jocassee) method of slice analysis. The ratio of the sum of all resisting forces divided by the sum of all forces tending to cause displacement under different loading conditions will be not less than the following:
i
_,t [-

, [ Ratio Dam Loading Condition 1.50 Full pond and steady state of seepage 1.25 Sudden drawdown of 25 ft at Keowee and 30 ft at Jocassee 1.25 Construction (reservoir empty) 1.05 Full pond, steady state of seepage, and seismic loadings The dams will be constructed, maintained and inspected consistent with their function as major hydro projects. The safety of such structures is the major objective of Duke's designers and builders, with or without the presence of the nuclear station.
2.4.4 GROUNDWATER The site lies within the drainage area of the Little and Keovee Rivers which flow southerly into the Seneca River and subsequently discharge into the Savannah River.
Groundwater in the general area occurs as free groundwater within the sapro-lite soil and migrates slowly at a gradient approaching the topographic slopes.
Water discharged on the surface at the site will percolate downward and mix with groundwater moving southeasterly toward the Keowee River and its tribu-i O tary creeks. The soils at the site should act as an effective barrier to the migration of radionuclides. Soil samples have been tested to establish predictable quantitative rates of migration.
The construction of Lake Keowee will not adscreely ffect groundwater con- ,
ditions at the site, and the infiltration of domestic wells should not be ,
possible under the existing or future groundwater conditions. Drainage facilities will be provided to intercept groundwater at northern side of the site yard.
Refer to Appendix 2C for a detail report on Groundwater Hydrology and to 4
Appendix 2D for Field Permeability Tests.
2.5 GEOLOGY The 21 borings completed at the Oconee Nuclear Site, supplemented by in-formation from the nearby Keowee Hydro Site borings, have been sufficient for a deterinination of the geologic structure and petrography, and their j relationship to the proposed construction. The exploration is sufficient to permit continuing design and construction.
The structures will be founded on normal Piedmont granite gneisses. The
- construction characteristics of the residual soils overlying the rock are well known and should present no problems in design or construction. The rock underlying the site, below surface weathering, is hard and structurally sound and contains no defects which would influence the design of heavy structures, e
_ An nnOO7 2-9 VM
The southeastern Piedmont rocks are highly stable seismologically, and the ,
Oconee Nuclear Site should be one of the nation's most inactive areas with respect to earthquake activity.
A detailed Geology Study of the site is included in Appendix 2E.
2.6 SEISMOLOGY No active or recent faulting has been recognized in the area of the proposed site. The closest known fault is the Brevard Zone, approximately 11 miles northwest of the site.
The foundations of the proposed Reactor Buildings will be located on rock.
This rock has excellent strength properties and relatively small amplifica-tion of ground motion resulting from an earthquake.
Concervatively, it is estimated that the maximum vertical and horizontal ground acceleration that might be experienced at the site is on the order of five per cent of gravity. This maximum ground acceleration is predicted on an earthquake of a Richter Magnitude less than five located in the Brevard Zone at its closest location to the site.
