- i-SintMARY AND CONCLUSIONS t

This Addendum to the Final Environmental Statement was prepared by-the U. S. Atomic Energv Commission, Directorate of Licensing.

1.

This action is admin 'strative.

2.

'The proposed action 1.

the issuance of operating licenses to the Duke Power Company for the startup and operation of Oconee Units 2 er.d 2 (Docket Nos. 50-270 and 50-287) located on Lake Keowee in Oconee County, South Carolina.

3.

The " Final Environmental Statement related to the Operation of Oconee Nuclear Station Units 1, 2 and 3" was published by the Directorate of Licensing in March 1972.

Paragraph 2 of the Summary and Conclusions pointed out that "this statement con-siders the environmental impact of the simultaneous operation of all three units," although the action at the time was con-cerned with the proposed issuance of a license to operate Unit 1.

4.

In connection with the proposed issuance of operating licenses for Units 2 and 3, the Final Environmental Statement was reviewed cnd it was determined that the Statement sets forth an adequate analysis and evaluation of the environmental impact of the proposed actions.

Nevertheless, this addendum to the FES is issued in order to pro-vide a progress report on the Station's continuing monitoring program and to update certain "need for power" information.

The information set forth in this addendum is not of sufficient impor-tance to warrant _its circulation for comment, and accordingly, the addendum is being issued as a part of the Final Environmental Statement.

5.

On the basis of the analysis and evaluation set forth in the Final Environmental Statement, as supplemented by the material in this Addendum, and after weighing the environmental, economic, technical, and other benefits of Oconee Nuclear Station 1 hits 2 and-3 against environmental and other costs and considering available alternatives, it is concluded that findinno in the FES are reaffirred; that the required monitoring programs have been developed and are incorporated as part of the Technical Specifications for the Oconee Station; and that the further actions called for under the National Environmental Policy Act

. of 1969 (NEPA) and Appendix D to 10 CFR Part 50 are the issuance of operating licenses for Oconee Units 2 and 3, subject to the condition that the applicant shall continue and inodify as neces-sary the comprehensive monitoring program described in Appendix B to operating License No. DPR-38 Technical Specifications for Unit 1 and which will be made a part of any licenses issued for Units 2 and 3.

< Introduction On November 6,1967, the Duke Power Company was issued construction permits CPPR-33, CPPR-34 and CPPR-35 for Oconee Units 1, 2 and 3, respectively. On June 2,1969, Duke applied for operating licenses for these three units.

The Oconee Nuclear Power Station is part of the Applicant's Keowee -

Toxaway Project located on the Keowee River (a tributary of the Savannah River) in northwestern South Carolina.

Construction of the project was started in 1967. When completed, ja will consist of a series of man-made lakes serving nuclear, hyd c and pumped storage l

generation. The initial hydroelectric development of the project consists of two lakes. The lower lake, Lake Keowee, is formed by dams on the Keowee and Little Rivers.

A canal connects the two bodies of water forming one lake with a surface area of 18,500 acres and some 300 miles of shoreline. The Keowee Hydroelectric Station, located at the Keowee Dam, consists of two 70 MW generators which began operation in 1971. Upstream some 11 miles from the Keowee Dam, the Jocasse Dam rises 385 feet to form Lake Jocassee and back a 7565 acre lake into the steeply rising flanks of the Blue Ridge Mountains.

The Jocassee Hydroelectric Station is scheduled to go into operation in early 1974 and, initially, will have two 152.5 MW reversible pump turbines. Two additional reversibic pump turbines of the same size are -

scheduled to be inatalled in 1975, bringing the Jocassee facilities' The total output to 610 MW of reversible pumped storage output.

hydroelectric power will only provide peaking power and, while a valuable supplement, is no substitute for base-loaded steam-generated electricity.

The Oconee Nuclear Station consists of three pressurized water reactors, each rated at 2568 MW thermal (MWt).

A steam turbine-generator associated with each reactor will use this heat to provide 886.3 MW (net) of electrical power capacity. Total capacity of the station will be 2,658.9 MW. Unit 1, which was scheduled to be available for the summer of 1971, was delayed by several preoperational problems.

Oconee 1 vent critical on April 19, 1973 but it is questionable whether core physics and startup testing can be completed in time for Fuel the plant to contribute fully to the 1973 summer peak loads.

loading for Oconee 2 has slipped from March 1973 to August 1973 so that, at best, this plant will not be on the line until 1974. Oconee 3 is in the final stages of construction.

. The arrangement of the Oconee Nuclear Station is shown in fig.1.

The intake structure is located in the lower center of the picture with Keowee Dam in the upper right. A more encompassing view of the overall site is shown in fig. 2.

The meteorology tower is visible (above unit 3) along with the Visitor's Center on the hill above the station and discharge structure. The overall layout of the Oconee Nuclear Station, Lakes Keowee and Jocasse and the associated hydroelectric plants are shown in fig. 3.

Af ter review of the Final Environnental Statement it was determined that the Addendum should update the need for power in the Applicant's service area and should examine compliance with the original conditions for the protection of environmental values, which were :

(a) Accumulate information required to establish baselines for the evaluation of thermal, chemical and radiological effects of station operation on terrestrial biota and aquatic biota in Lakes Keowee, Hartwell and Jocassee.

(b) Develop and implement a comprehensive monitoring program that will permit surveillance during plant operation of thermal, chemical, and radiological effects on terrestrial biota and on aquatic biota in Lakes Keowee, Hartwell, and Jocassee.

(c) Monitor concentrations of chemical discharges into Hartwell Reservoir.

(d) Monitor the temperature of the condenser cooling discharges into lake Keowee.

This information is included in the following sections.

. Environnental Monitoring Programs Since the Final Environnental Statenent was issued (March 1072), a non-radiological environmental monitorine progran has been established and incorporated as Appendix B to Operating License DpR-38 for Unit 1 The data developed as required by the Final Environmental Statement.

from the program will provide cuantitative information on the effects of chemical and thermal discharaes from Oconee Units 1, 2 and 3 on the aquatic and terrestrial life associated with Lakes Keowee and Hartwell.

Samples from throughout the lakes are being analyzed for chemical com-position. temperature and dissolved gases.

The general aquatic surveil-lance includes samples to detect and cuantify the effect of the Station's l

operation on plankton, periphyton, zooplankton, phytoplankton and benthos.

An extensive fish samplina program will identify the spawning areas, species composition, size ' class and age comnosition of fish in Lake The overall Keowce with emphasis on the intake and discharge areas.

studies will provide data that can be usel to evaluate the effectiveness of the skimmer wall, submerged weir and intike and discharge desien in minimizing thermal and entrainnent effects.

This program will be con-tinued during the operation of Units 2 and 3.

A summary of the sampling schedules and locations is outlined in Table 1.

To assure that concentrations of chemicals released from the Oconee in Hartwell Station will not be toxic to the aquatic environment Reservoir, limits have been placed on the tyne and quality of liquid The plant waste streams collected in the waste water dischargea.

collection basin are required to be treated to produce essentially a The two most important indicators of chemical com-neutral effluent.

position - pit and conductivity - must be sampled and recorded at least once per day.

To monitor the effect and extent of thermal enrichment of Lake Keowee, sample. are required to be routinely taken at nine sampling locations on' Lake Keowee and at five locations on the Keowee River and Hartwell Temperature and dissolved oxygen measurements are reouired Reservoirs.

to be taken at ten (10) foot intervals on all lake sampics.

B.O.D.

measurements on Lake Keowee are required to be taken at one foot, ten feet and bottom depths.

To supplement the routine " grab" samples, three multipoint continuous water temperature monitoring stations have been. installed at the entrance to the intake canal, the discharge area and the connecting canal between the Little River and Keowee arms of the lake.

In addition to the surveillance programs being conducted by Duke Power Company, the Fishery Research Division, Bureau of Sport Fisheries and tJildlife, Department of the Interior has under way a ten-year Southeast Reservoirs Investigations Project. The resident office is at Clemson, South Carolina. A major part of the program is being carried out on Lakes Jocassee, Keowee and Hartwell to establish the effect of heated ef fluent, pumped storage and hydro-electric generation on fish population, distribution, movement, growth, production and harvest and on production and utilization of plankton and benthos. The projects being conducted in FY 73 are listed in Table 2.

Between the studies being conducted by the Bureau of Sport Fisheries l

and the environmental surveillance programs being conducted by Duke, the effects of the Oconee Nuclear Station on the equatic environment are being adequately monitored.

I Need For Power The need for power in he applicant's service area is discussed in Chapter X (p 156) b.e Final Environmental Statement. As a result of more recent data submitted both by the Applicant and by other utilities in the southeast who.have recently applied for tion permits, some amplification of the need for power

-construc section was deemed desirable.

The applicant's service area' encompasses approximately 20,000 square udles in west-central North Carolina and northwestern South Carolina- (Fig I-1 of FES). Although the service area 1

represents only a fourth of the total land area of the Carolinas,

it is home for about 3.3 million people - more than half of the states' populations.

The Duke Power Company serves about 907,000 residential customers and 145,000 other customers and is the principal supplier of electric energy in 44 of 56 countries in its service area. It supplies electric service directly to retail customers in 216 cities, towns and unincorporated communities. It also sells power at wholesale to 40 other incorporated municipalities and to a nudb'er of Rural Electrification Administration cooperatives and private utilities.

~ ~ -

l

, past Growth of the Power Svstem The Applicant's average and _ peak loads for the past ten years were analyzed. Since 1962, the average. nual growth rates in the four' main categories of customers wer as follows:

Table 3 Average Annual Growth Rates Commercial 12.9%

Residential 9.2%

Industrial 8.6%

All Other 10.1%

However', the peak loads, which is the basis on which the applicant has ' to plan generating capacity, can of ten show variations from the average load growth for a particular year.

In 1972, for example, the ' total energy sales increased by only 8.1% due to extrerely mild weather conditions during the year, yet the 1972 peak load of 7450 ~M4 (July 24,1972) exceeded the 1971 peak load of 6622 MW (June :28,1971) by 12.5%.

Future Crowth of Peak Load and Generating Capability The Applicant's nresent generating facilities consist of 10 steam

' electric plants with a capability of 5439 }N, 29 quick-start combustion turbines with a total capacity of 638 MW and 27 hydroelectric plants with a capability of 1003 151.

Of the 27 hydro stations, almost all of which were installed prior to 1928, two-thirds of these stations can add less than 27 MW each of short-term peaking power. As late as 1967, the applicant had essentially no peaking combustion turbines: since then, Duke Power 7

Compa_ny, like other utilities, has been using these units to supple-ment. the steam plants during peak loads because of their capability of being able to be brought-on and taken-off the line rather quickly, their relatively-low installed cost per kw, their relatively short delivery times and the minimal governmental approvals required.

'The : applicants' 'last major addition of these units was the installa-tion of ten combustion turbines totaling 196 MR at Buzzards' Roost, S.C. in 1971.

The extent to which the Applicant used the. combustion turbines and hydro capacity to supplement the base-loaded steam plants for peak power periods during the past six years is shown in Table 4:

Since the -Final Environmental Statement was issued a year ago, the j

need for power from the Oconee Station has become even more necessarv.

The summer peak on the Duke Power System has cenerally occurred in the months of June and July.

It generally takes about three months from the time a nucl

,lant achieves criticality until the core physics u

and power esr,.

ests are completed and the plant is ready for commercial op b

Inasmuch as Oconee 1 did not go critical _until April 19, 1973, the unit may not be available to assist in meeting the applicant's peak summer load.

For planning purposes, it has been included in the 1973 planned additions. Oconee 2 is scheduled for commercial operation about December 15, 1973; for practical purposes, this has been considered as a 1. ?4 addition. Oconee 3 has been included in the 1975 planned additions.

. Regional Relationships The applicant's' service area is in the Federal Power Commission's

' Region Ill. As a member of the Southeastern Electric Reliability Council (SERC), (one of nine regional coordinating councils which constitute the National Electric Reliability Council), the apolicant conducts reliability studies in cooperation with other Region III utilities.

The. applicant is also a member of SEPC's Virginia-Carolina Subregion (VACAR). Besideo Duke Power Company, the other members of VACAR are the Virginia Electric Power Company (VEPCO), Carolina Power and Light Company (CP&L), South Carolina Electric and Gas Company (SCE&G) the Southeastern Power Administration (SEPA), Yadkin, Inc. 'and the South Carolina Public Service Authority (SCPSA).

Through VACAR and SERC, planning for major transmission interconnections with the other. utilities are conducted and operating agreements for power l

exchange arrangements are made within the region and with similar reliability. groups in the mid-Atlantic and east-central sections of the country.

Within the next five years, plans call for Duke Power Company to install 550 miles of 500 KV transmission interconnections with neighboring utilities, Carolina Power and Light Company, Appalachian Power Company and Georgia Power Company. By the end of 1972, 160 miles of the system had been completed. The existing interconnections with neighboring utilities was used extensively in the past few years for the exchange of power during periods of heavy load. Since 1968, the applicant has purchased from 1.5 to 2.6 billion kilowatthours each year.

Through VACAR, the applicant has made arrangements for the purchase To of a small amount of-power from several neighboring utilities.

partially replace the power that was not available in 1972 from Oconee 1 being delayed, Duke Power Company made arrangements for In total, short ~ term purchases of power during the summer of 1972.

i-these short term purchases amounted to 344 MW and included 166 MW from the Southern Company,140 MW from American Electric Power To cover the Company and 38 MR from the Appalachian Power Company.

-delays in Oconee 2, the applicant has made arrangenents with SCE&G 1973 and with APC for the purchase of 250 MW from May through Augus:

These for the purchase of 250 MW from May through October 1973.

short term purchases of power were considered advisable to provide

. reserve capacity in case of-forced outages of generating equipment 4

. or unpredictable high power _ demand. In the long-run, dependence on purchased power - even if it is available - to maintain needed reserve capacity is undesirable because:

1.

Purchased power is less reliable as a result of the greater number of interconnecting relay stations and the exposure of transmission lines between the generating stations and the load centers.

2.

Purchas td power is not always available on a firm basis and 1

of ten such power can only be contracted for on an inter-ruptible basis. In the latter instance, the power require-ments of the seller take precedence over the needs of the purchasing utility and, therefore, the power may not be available.

3.

Purchased power generally costs the utility more than power generated within its own system.

Reserve Capability Of crucial importance to an electric utility is the amount of generating reserve capacity. This is the generating capability of power available in excess of the peak load.

Capacity in excess of estimated load is necessary to increase the _ probability of maintaining uninterrupted service to all firmly connected loads.

This reserve capacity provides for contingencies such as higher-than-predicted loads, dry weather which decreases hydroelectric capacity, delay in startup of new units, transmission system failures, storms and natural disasters which knock-out part of the system and the unscheduled, forced shut-down of generating units.

Duke ; Power Company's criteria for reserves include allowances at the time of peak load for:

1.

Load increases brought on by severe weather.

(Peak load estimates _ are based on average weather.)

-2.

The unscheduled outage of the largest generating unit.

3.

Forced outages or reductions in capability of other generating units, based on operating experience.

4.

Forecast error or the outage of additional generation equivalent to the largest unit.

1

13 -

The 1973 installed generating capacity (including Oconee Unit 1) will be 8572 MW.

With a forced outage of the largest generating unit, Oconee Unit 1, the anticipated summer peak load of 8,101 MW will exceed system generating capacity by 411 Ms'.

Clearly, the reserve criteria will not.be met, and addit.ional power rust be purchased and/or loads reduced.

In 1974, the system capacity (including both Oconee Unit 1 and 2) will be 10,827 NW.

With the outage of Belews Creek No.1 (1,143 MW) and an anticipated summer peak load of 8,838 MW, the system will have an excess reserve of 846 MW.

This reserve is not suf ficient to meet Criteria No. 4 above.

I The installed capacity in 1975 will be 13,161 IN (including Oconee Units 1, 2, and 3). With the outage of either Belews Creek No. 1 or i

2 (1,143 MW), and the anticipated summer peak load of 9,635. MW, the installed reserve will be 2,383 MW, which should be adeauate to meet the reserve criteria.

Resource Planning Table _6 summarizes Duke Power Company's estimated peak loads through 1975, the estimated installed capacity including the three Oconee units and the agreements ' for ourchased power which the applicant has negotiated.

The table illustrates why all three units of the Oconee Station are required to provide an uninterruptible power supply.

Cost.of Alternate Power hs of'Mardv 30, 1973, the total installed capacity within the Duke

- Power system that is provided by combustion turbines and diesels is 638 MW.

Like hydroelectric power, combustion turbines cannot be considered as a substitute for base loaded steam plants. Codbustion turbines are designed for peaking service.

Generally, the plant capacity fa'ctor for. combustion turbines in a utility system is not over 12 to

- 14% and may be as low as 3 to 5%.

However, in the applicant's system, the turbines were (in 1971) in use an average of 35% of the time. In 1973s and'1974 when the need - for additional base-loaded generating

- capacityc is the most critical, combustion turbines could not be offered as an alternative to Oconee.

The lead time on even small, standard J

design gas turbines is over a year.

l L

. In the long run, gas turbines.could not be considered a viable alter-native to the Oconee units because of their high operating and umin-tenance costs even if an adequate supply of oil or gas were available.

figures from the Applicant (3/30/73), the Acccrding to the latest average cost of burnup of nuclear fuel over the next 10 years in the Oconee Station is expected to be approximately 15 cents per million At 15 cents per million BTU, and assuming a heat. rate of BTU.

10,000 BTU per net Kilowatt hour, each of the 866 megawatt Oconee units will have a daily fuel expense based on full load operation of approximately $31.900.

If, during periods of milder-than-normal weather in the winter of f

older fossil-fired units were to be used to generate energy 1973-74, to replace that which would not be available should operation of Oconee Unit 2 be delayed, the cost of fuel consumed per day would be

$103,900.

This is based upon a current fuel cost of 46.7 cents per million BTU and an average heat rate of 10,674 BTU per kilowatt hour Thus, each day that each unit of to produce 886 megawatts each day.the Oconee Station should be del mild weather results in increased fuel expense of approximately $72,000.

Thus, having to replace result in a fuel cost of $289,500 energy that could be generated by one unit of Oconee Station with energy generated by combustion turbines during cold weather would cost an additional generating expense' of $257,600.

Lakes Keowce and Jocassee are expected to attract extensive recreational Duke Power Company has encouraged public recreation usage of use.

their impounded lakes. At Lakes Keowee and Jocasse the Applicant has taken a number of actions to permit public enjoyment of the water and the scenic Blue Ridge Mountains that form a backdrop for the lakes.

The Applicant donated 1,000 acres of land to South Carolina for development of the Keowee-Toxavay State Park.

To provide access for boate rs, fishermen, swimmers, campers, picnickers and hikers, Duke Power Company also constructed eight recreational areas around Lake Keowee and three around Lake Jocasse.

In each of these areas the company has installed boat launching ramos and parking facilities.

Ilese areas range in size from 21 acres to a 155 acre complex that will involve campgrounds, complete sanitary facilities and bathhouses, boat storage facilities and marinas.

Near the upper end of Lake Jocasse, a wilderness campground is being developed, accessible only by hiking trail or water.

Duke Power Company has worked with the wildlife and conservation services of both North and South Carolina in providing game management areas and hunting refuges. More than 68,000 acres of land around Keowee-Toxaway have become a game management area by a working agreement with' the wildlife commissions of the two states.
