SUMMARY

1.1 PURPOSE The Oyster Creek Nuclear Generating Station (OCNGS) utilizes an open cycle cooling system in which the main condenser cooling water is supplied via a man-made intake canal from Forked River and then discharged to Oyster Creek. Although the cooling system consistently meets pertinent environmental regulatory limits, there have been environmental impacts. To determine the benefits and costs of implementing a cooling system alternative to the existing condenser cooling system, Ebasco evaluated engineering, cost, licensing, and environmental factors, of sixteen (16) open cycle and closed cycle cooling water systems.

The study, "Alternative Cooling Water System Study",

November 1977 (Reference 1),

identified four "preferred" cooling systems: natural draft cooling tower, round mechanical draft cooling tower, fan assisted natural draft cooling tower and discharge canal to bay. Of these four, the study concluded that the natural draft cooling tower system is the optimum.

The purpose of this study is to update the technical, economic E

and environmental findings of the original study with respect to the two (2) preferred cooling water alternatives, i.e. natural draft cooling tower (NDCT) and round mechanical draft cooling tower (RMDCT).

The technical and economic evaluations are presented in Volume

1. Environmental evaluations are presented separately in Volume 2.

1.2 SCOPE This study is performed in accord with the scope of work described in Ebasco' s proposal "Update of Alternate Cooling Water System Study for Oyster Creek Generating Station", December 1991.

4

The two best closed cooling alternatives from the original study, the natural draft cooling tower.(NDCT) and round mechanical draft cooling tower systems (RHDCT), are evaluated. Detailed information contained in the original study was reviewed and the information updated for those technical, cost and environmental aspects that have been superseded based on current plant conditions, cooling system technology, environmental and regulatory criteria.

For example, cooling system investment and operating costs are updated for today's equipment costs, GPUN's economic factors, remaining plant operating life, and forecasted replacement energy costs.

In this volume technical and economic aspects of the NDCT and RMDCT alternatives are evaluated in the following tasks:

1)

Review the original study and confirm or update the criteria and assumptions consistent with current site characteristics, plant design, performance, environmental and regulatory requirements;

2)

Update the technical design, including preliminary design, performance and cost information from a cooling tower vendor;

3)

Update the Ebasco computer program "Economic Selection of Steam Condensing System" (CSIZE2011), including:

o site, plant and cooling system design features and performance o

major equipment prices, e.g. cooling towers, pumps o

balance of plant material and installation costs o

GPUN economic factors 1.3 RESULTS Two arrangements of evaporative cooling towers are evaluated:

a single concrete, hyperbolic natural draft cooling tower (NDCT);

and two (2) 50% capacity round mechanical draft cooling towers. A 5

schematic flow diagram and layout drawing are given for the NDCT in Exhibits 5 and 6, respectively, and for the RMDCT in Exhibits 12 and 13, respectively.

Condensing. system and plant overall performance, investment

costs, and comparable annual costs including demand and energy charges for differential generation with respect to the existing system are given in Exhibits 29 and 30 for the NDCT and RMDCT, respectively.

Cold water would be pumped by circulating water pumps through 12 ft (NDCT) or 11 ft (RMDCT) diameter reinforced concrete conduits to and from the existing circulating water intake and discharge tunnels. The conduits would be buried.

Circulating water system total head requirement is approximately 74.4 ft for the NDCT and 68.6 ft for the RMDCT. To satisfy the intake tunnel design pressure of 41 feet, the total pumping head is divided between four (4) 800 hp vertical type circulating water pumps located at the cooling tower and (4) 1500 6

hp horizontal type booster circulating water pumps located in the hot water return piping.

Circulating water'systen electric power requirements for pump, fan and miscellaneous equipment motors are provided using existing 4160 V 1A, 1B and dilution pump switchgear, new 4160 V switchgear and new 480 V power centers.

Intake water would be used for cooling tower makeup and would require pretreatment in a brine clarifier/reactivator to reduce the calcium hardness. Makeup flow would be approximately 15,000 gpm based on operating the circulating water at 2 to 2.5 cycles of concentration. Cooling tower blowdown is calculated to be a volume of about 7,500 gpm and would be piped to the discharge canal.

Clarifier sludge would be dewatered and compacted for offsite disposal.

Compared to the existing cooling system, the use of cooling towers will reduce plant net capacity and generation due to higher turbine exhaust pressure and higher auxiliary power demands. At design temperature conditions net capacity would decrease by about 15 MW for the NDCT and 19 MW for the RMDCT.

1.4 CONCLUSION

S Incorporation of either cooling tower alternative appears technically feasible subject to more detailed engineering and cost studies of the cooling tower, circulating water pipe, water treatment equipment arrangements, electric power

supply, circulating water pump total head and system operational 8

l requirements with respect to limitations of the existing cooling system (i.e. intake tunnel design pressure).

The economic impact of either the NDCT or RMDCT is high due to l

significant investment cost, and reduced net generation. Total comparable costs are essentially equal.

2.0 DISCUSSION 2.1 METHODOLOGY The original study evaluated and selected the natural draft and round mechanical draft cooling tower systems as "preferred" based on cost and environmental considerations. For this study, these cooling system alternatives are evaluated technically, economically and environmentally based on today's criteria.

Compared to the existing cooling system, incorporation of an alternative cooling system utilizing cooling towers will reduce plant net output. Cooling water temperature is warmer, resulting in higher condenser pressure and reduced generator output. Station auxiliary power consumption increases from greater circulating water pump power and cooling tower fans.

Each cooling system is technically and economically evaluated to identify the optimum design using Ebasco's computer program "Economic Selection of Steam. Condensing System" which was used in the original study. Program description is given in Appendix A.

Cooling system alternatives are evaluated in two levels of detail.

In the first level of detail a cooling system economic optimization study is performed on a comparative basis to identify the technically acceptable and economically preferred NDCT and RMDCT system process specifications. The evaluation is based on cooling tower design, performance and cost parameters provided by a cooling tower vendor for alternative cold water and range temperature conditions. In the second level of detail, the cooling tower vendor provides refined design, performance, and cost data for the specific optimized cooling tower specifications. This data is used to perform more detailed engineering, economic and environmental evaluations.

2.2 COOLING SYSTEM DESCRIPTION 2.2.1 EXISTING COOLING SYSTEM Exhibit 1 shows the Oyster Creek NGS site bounded by Barnegat Bay to the east, Forked River to the north and Oyster Creek on the south. The condenser cooling system, Exhibit 2, is an open-loop cooling system whereby the condenser heat load is ultimately discharged to Barnegat Bay via intake and discharge canals connecting Forked River and Oyster Creek, respectively. Four circulating water pumps convey the mixture of salt and fresh water from Barnegat Bay and Forked River through the intake canal and the condenser to the discharge canal. Circulating water pumps are located in the intake canal. A dam separates the intake and discharge canals.

The turbine exhaust steam condenser consists of three single-pass, single pressure shell.s manufactured by Worthington. The original tube material was replaced with titanium in the early 1970s. Condenser design parameters from References 2a and 2b are:

No. Shells 3

Surface Area per Shell 141,000 sq ft Cooling water flow per Shell 150,000 gpm No. Tubes per Shell 14,562 Tube Length 42.5 ft Tube Material Titanium Tube Diameter x Wall Thick.

7/8 in x 22 BWG Tube Cleanliness Factor 95%

The condenser is supplied by four (4) 115,000 gpm, 28.5 ft

TDH, 1000 HP vertical type circulating water pumps located at the intake canal pump house. The intake canal also supplies three (3) 800 hp dilution pumps that may be used to regulate discharge canal water temperature.

11

Cooling water is conveyed from the intake canal through the condenser to the discharge canal via 10.5 ft x 10.5 ft concrete intake and discharge tunnels. Tunnel, condenser pipe and valve arrangement facilitates condenser tube backwashing.

The circulating water system intake tunnel has a design pressure of 41 ft which restricts the maximum allowable circulating water pump discharge pressure, the number of pumps and condenser water boxes in

service, and condenser backwash procedures (Reference 2c).

The performance of the existing condensing system, turbine generator output and plant net generation is calculated in Exhibit

3. At the average annual cold water temperature, the existing condensing system produces nominally 640 MW gross.In order to allow for comparability with the cooling tower alternatives, the existing condensing system was evaluated at an equivalent ambient temperature. This results in an 84 F cold water temperature.

A single cooling tower can handle the total condenser and auxiliary service water heat load and flow requirement.

Major equipment includes:

o hyperbolic counterflow natural draft cooling tower and basin o

horizontal and vertical circulating water pumps (8 total) o circulating water concrete conduit o

circulating water pump house o

electric switchgear, cables o

makeup water pumps, piping o

makeup water treatment system o

water treatment sludge disposal system o

blowdown water piping o

condenser tube cleaning system Cooling Tower The natural draft or hyperbolic counter flow cooling tower relies on the structure's "chimney" effect to induce ambient air to flow upward through the tower "fill". Hot circulating water flows over the fill and is cooled by the air flow via evaporative and convective cooling.

One NDCT is required. Cooling tower design, performance and budget cost data for comparative analyses is shown in Exhibit 22.

Data are provided for towers with approach temperature from 12 to 16 F and range temperatures from 16 to 24 F.

The economically optimized tower is approximately 600 ft tall and has a base diameter of 409 ft.

Circulating Water Conduit The cooling tower is assumed to be located at the north side of the plant. Reinforced concrete conduit convey the circulating water between the cooling tower and existing intake and discharge tunnels.

13

The design pressure of the intake tunnel is 41 ft. This limits the allowable circulating water pump discharge pressure. For closed cooling alternatives utilizing cooling towers that have a high total head (for the NDCT system approximately 74 ft), the overall system pumping head requirement is minimized by the use of large diameter conduits.

Furthermore, the intake tunnel pressure limitation requires that the total pumping head be shared between two sets of circulating water pumps. One set of four (4) CW pumps are located in the cooling tower basin and a set of four (4) booster CW pumps are located in the return piping to the cooling tower.

The TDH of each pump must be specified such that the following criteria are met:

a.

cumulative pump head equals the sum of pipe friction, condenser friction and cooling tower pumping head;

b.

the intake tunnel 41 ft pressure limit is not exceeded during all operating modes;

c.

main and booster circulating pump NPSH requirements are met;

d.

maximum siphon head is not exceeded (typically 25-26 ft).

A CWS hydraulic gra.de line given in Exhibit

7.

For the optimized case, the circulating water flow rate is about 416,000 gpm and the reinforced concrete conduit diameter is 12 ft.

Total conduit length is about 2.,900 ft. Vertical circulating water pump head is 26.4 ft and the horizontal booster circulating water pump head is 48 ft. Intake tunnel pressure is 39 ft and condenser siphon head is about 19.5 ft.

Electric Power Supply Cooling system electric power requirements for the circulating water pumps, makeup water pumps, water treatment equipment, valve motors and miscellaneous equipment will be supplied from existing 14

I 4160V buses lA, IB, and dilution plant switchgear, new 4160V switchgear, new 480V power centers and motor control centers.

A conceptual one line diagram of the major electrical components of the NDCT power supply is shown in Exhibit 8. The existing 4160 V switchgear buses 1A and 1B will be used to supply l

the four (4) new 800 hp circulating water pumps. The. existing dilution pump 4160 V switchgear would feed two (2) 1500 hp booster pumps, an 400 hp makeup water pump and a new 480 V power center #1.

A feed is provided from startup transformer SB to new 4160 V switchgear to supply the other two (2) booster pumps, makeup water pump and new 480 V power center #2.

l Makeup Water Treatment l

Intake canal water is used for cooling tower make-up. Intake water analysis from the original study is analyzed in Exhibit 9.

l Calcium hardness must be reduced by lime softening. The reduced hardness will enable the cooling tower to operate between 2 to 2.6 cycles of concentration. At. the design wet bulb temperature the makeup water rate is approx:imatelfy 15,000 gpm. About 7,500 gpm is lost to evaporation and 7,500 gpm is discharged to the discharge l

canal. Makeup water is supplied by two (2) 50% capacity 400 HP pumps which would be located in the existing intake canal CW pump l

house.

Water treatment schematic diagram is shown in Exhibit 10.

Raw water is pumped to the brine clarifier/reactor where chemicals are added to enhance the removal of calcium hardness. The treated effluent is discharged to the cooling tower. The excess sludge is collected and discharged to a thickener where it is further concentrated before it is sent to a filter press to be dewatered to a truckable solid for offsite disposal.

2.2. 3 ROUND MECHANICAL DRAFT COOLING TOWER SYSTEM Cooling tower arrangement, system flow diagram and layout for the Round Mechanical Draft Cooling Tower (RMDCT) system are given in Exhibits 11, 12 and 13. Major equipment is the same as for the NDCT except that two (2) RHDCT are required, and 2 additional new 480 V power centers are required to supply the cooling tower fans.

Cooling Tower The round mechanical draft cooling tower utilizes fans to induce the air to flow through the cooling tower. Cooling tower design, performance and cost data for comparative purposes are given in Exhibit 23. The two (2) cooling towers are assumed to be located north of the plant. Basin water flows to a common intake pump structure.

Circulating Water Conduit Conduit diameter would be 11 ft based on the optimized case flow of 373,000 gpm.

Hydraulic gradient is shown in Exhibit 14.

Circulating water system total head is 68 ft, which is divided between the main circulating water pump (26.1 ft) and the booster pump (42.5 ft). Intake tunnel pressure is 39 ft and the condenser siphon head is 16.8 ft.

Electric power SUpRlR A conceptual one line diagram of the major components of the RMDCT power supply system is shown as Exhibit 15. Power supply from existing and new 4160 V switchgear for the four CWPs, four booster

CWPs, two makeup water pumps and two 480 V power centers are the same as for the natural draft cooling tower. Two additional 480 V power centers are provided for the cooling tower fans.

16

c If Makeup Water Treatment l

The system is the same as for the NDOT. Circulating water analysis is shown in Exhibit 16. At the design wet bulb temperature the makeup water flow is 15,400 gpm based on an evaporation loss of 7,700 gpm and blowdown flow of 7,700 gpm.

2.3 COOLING SYSTEM OPTIMIZATION INPUT DATA 2.3.1 COOLING SYSTEM PARAMETER ALTERNATIVES I

Condenser tube water velocity If The existing condenser design flow rate is 450,000 gpm and the condenser tube water velocity is 6.3 ft/s. The condenser tube lf velocity affects the cooling water temperature rise, flow rate, condenser pressure and generator power output. Higher tube velocity results in higher generator output due to better condenser heat transfer performance and reduced turbine exhaust pressure. But the higher flow rate increases the cooling tower cost, pump head and pump power. Lower tube velocity results in lower generator output, but also lower cooling system cost, pumping head and power.

Titanium condenser tubes may be expected to operate Df satisfactorily over a wide velocity range. For optimization of new cooling water systems the economically preferred titanium tube l

design velocity is typically between 6 to 12 ft/s. However for this study, in which the existing condenser and circulating water conduits are fixed designs, the water velocity was evaluated over the range of 5.0 ft/s to 7.2 ft/s based on the following n

considerations:

17

o low velocity (high cooling water temperature range) to reduce cooling tower, pump and piping costs, pumping head, and satisfy the intake tunnel design pressure limitation; minimum velocity for the Amertapp tube cleaning system (for study purposes only) is 5 ft/s; o

high velocity (low cooling water temperature range) to increase condenser performance and generator output.

Resulting condenser flow rate and water temperature rise versus tube water velocity, based on the full load condenser duty of 4110 million Btu/hr (at 1860 MWt),

3 shells and 14,562 tubes/shell (7/8 inch diameter, 22 BWG) are:

Condenser Tube Water Velocity. ft/s Condenser Flow. grp Temp. RiseF 5.0 359,000 23.6 6.27 450,000 (design) 18.8 7.2 517,000 16.4 where temperature rise Heat Duty/(Gpm x 500 x Cp x SG) ; assuming water equal to 1.5 normal sea water concentration or 50,000 ppm, Cp = 0.94 and SG = 64.4/62.4 = 1.03.

Cooling Tower Flow Rate Cooling tower flow equals the condenser flow plus 10,000 gpm auxiliary service cooling water (flow to the turbine building closed cooling water heat exchanger).

Cooling Tower Ranre Temperature Cooling tower water range temperature (i.e. hot water inlet temperature minus the cold water outlet temperature) is governed by the condenser and auxiliary service water system heat loads and 18

flow rates. For this study, the cooling tower range temperature is assumed equal to the condenser temperature rise.

Cooling Tower Approach Temperature Cooling tower cold water temperature performance is governed by the "approach temperature" to the ambient air wet bulb temperature. The ambient wet bulb temperature is the same as in the original study, 74 F. This equals the mean coincident wet bulb temperature corresponding to the 2.5% summer (June, July, August, September) frequency dry bulb temperature (89F) for Atlantic City as given in Reference 7.

From Ebasco's experience with numerous cooling tower economic evaluations, the economically preferred cooling tower will generally have a high range! temperature (to reduce the flow rate and capital cost) and low approach temperature (to lower the condenser pressure and increase generator output). For this study, the range temperatures described above and the following cooling tower approach temperatures are considered:

NDCT:

12; 14; 16 F RMDCT:

8; 10; 12 F 2.3.2 PROJECT FINANCIAL CRITERIA A.

Material and installation cost escalation: 4.1 %/yr (reference 3c).

The escalation period is assumed to be three years based on system operation starting in 1995.

B.

Sales/Use Taxes: 5% of direct material cost.

19

I C.

Indirect Construction Ccot: 15 % of total direct escalated cost.

Indirect Construction Cost has been estimated as a percentage of total direct escalated costs based upon Ebasco's in house data.

Indirect Construction Costs include architectural/engineering and related services such as design, engineering, purchasing, expediting, inspection,

traffic, start-up
services, construction management, locally hired non-manual employees (secretary, bookkeeper, surveyor), cars, pick-up trucks, site trailers and office expenses to support a construction management team at the site.

D.

Contingencies: 14% of total direct and indirect escalated cost.

The contingency allowance has been estimated as a percentage of total direct and indirect escalated costs based upon Ebasco's experience. It covers the following items: conceptual quantities for earthwork, concrete, piping, and electrical; lack of firm pricing for major equipment; and the current phase of design (conceptual) for this study.

E.

Interest During Construction: 10%/yr (reference 3a).

F.

UtilitX's Expenses: 6% of total direct costs.

This is to cover GPUN's administrative, engineering and supervisory costs and taxes during construction, and is the same as used in the original study.

G.

Levelized Maintenance Cost: natural draft cooling tower, 2% of total investment; round mechanical draft, 3% of total investment cost plus $3,800 per fan.

H.

Leveliged Fixed-Charpe Rate: 23.42 % of the capital cost. This is the."carrying charge" need to cover expenses for return on weighted capital, book depreciation, income tax liability, property taxes and insurance.

It is equal to the sum of the capital recovery factor (calculated at the rate of return, below) plus 9.7% from the original study for taxes and insurance.

The economic evaluation period is 15 years from 1995 to 2009 when the plant's operating license expires.

2.3.5 TURBINE GENERATOR UNIT PERFORMANCE & LOADING REGIMEN Turbine Cycle Heat Balance The turbine generator is a General Electric TC6F-38 LSB unit with Valves Wide Open (105%; flow) gross output and heat rate of 670,005 Kw and 9,797 Btu/Kwh at 1.0 in HgA exhaust pressure.

Reactor thermal output is 1930 MW. Throttle steam conditions are 6,834,590 lb/hr at 965 psia and 1191.2 Btu/lb. Condenser heat duty is 4,360 MMBtu/hr. Exhibits 20a and 20b illustrate the turbine cycle heat balances for the Valves Wide Open case and the 100% load case, respectively.

Generator output may be calculated for various exhaust pressures using exhaust pressure heat rate correction factors shown in Exhibit 21 and the following equation:

Change in Kw = (-X Change in Heat Rate)*100/(100-% Change in Heat Rate)

Plant Operation The plant is assumed for this study to operate (base loaded) equivalent to a 75% capacity factor. For study purposes, the turbine generator is assumed to operate at 100% guaranteed load gross output and heat rate of 640,757 Kw and 9,821 Btu/Kwh, respectively, at 1.0 in HgA exhaust pressure, for 0.75

  • 8,760 hr/yr = 6,570 hr/yr. Reactor thermal output is 1860 MW. Throttle steam conditions are 6,509,130 lb/hr at 965 psia and 1191.2 Btu/lb.

Condenser heat duty is 4,110 MM Btu/hr.

The turbine cycle heat. balance for this case is shown in Exhibit 20b.

2. 3.6 CIRCULATING WATER SYSTEM LAYOUT Piping layout is shown in Exhibits 6 and 13 for the NDCT and HDCT, respectively. The cooling tower is located on the north side of the plant for both layouts.

New piping connects the cooling tower to the existing circulating water conduits. The new conduits are buried. Since ground water is close to the surface (less than 10 ft), pipe installation is assumed to require sheet piling.

Circulating water system TDH is calculated based on the following pipe arrangement:

2.3. 8 PRICING INFORMATION A.

Pricing Data Stored On Computer Vertical circulating water pump and motor budgetary costs were obtained from Ingersoll Rand Pump Division (reference 5).

Pump Type Pump Model Capacity, gpm Total Head, ft Efficiency, %

Motor HP/Volt/rpm Pump Price, $

Motor Price, $

Vertical, wet pit for salt water 58 APMA 110,000 42 87 15,000/4000/400 300,000 225,000 The above pump and motor prices were used to determine a "discount factor" to adjust vertical pump, horizontal pump and motor price data contained in the computer program. The discount factor was derived to be equivalent to the combined cost of a "composite" vertical circulating water pump consisting of one vertical CW pump and one horizontal booster CW pump. This was necessary for the computer program to determine a cost equivalent to two circulating water pumps arranged in series.

Discount factors used for the "composite" vertical pump and motor were:

Vertical pump: -4.01 on 1968 price list (or a 5.01 multiplier on the computer price);

Motors: -1.36 on 1975 price list (or 2.36 multiplier) 25

B.

Pricing Data Input Directly to Computer Current pricing data was quoted by vendors or estimated by Ebasco for major site development, circulating water intake structures, conduits, cooling towers, electrical equipment, power cables, local clearing, etc. Pricing data is listed in Exhibit 24. Land cost for noise abatement was excluded.

2.4 COOLING SYSTEM ECONOMIC OPTIMIZATION RESULTS The Ebasco computer program "Economic Selection of Steam Condensing System" was used to evaluate the design, performance, investment cost and comparable annual costs for NDCT and RMDCT.

Program description is given in Appendix A.

The computer analysis was performed for the following alternatives:

Condenser Tube Water Velocity. (ft/s) 5.0 -

7.2 ft/s in steps of 0.2 ft/s Cooling Water Approach Temperature (74 F wet bulb temperature)

NDCT:

12; 14; 16 F RMDCT:

8; 10; 12 F Natural draft and mechanical draft cooling tower technical, investment cost and annual cost computer results summary for each approach temperature are given in Appendix B. Investment cost includes all costs to erect cooling tower and basin, pumps, piping, intake and pump house structures, electrical, water treatment, etc.

Land costs to meet noise regulations have been excluded from this study. Annual cost (levelizeed) includes investment fixed charge, O&M, plus adjustment (energy/demand charge) for differential net 26

generation compared to the existing condensing system. Capitalized costs = total annual cost/levelized fixed charge rate (23.42%).

2.4.1 NATURAL DRAFT COOLING TOWER SYSTEM Total investment cost, comparable annual cost and capitalized annual cost, are given in Exhibit 25. Investment and capitalized costs are also graphically shown in Exhibit 26.

NDCT investment costs range from $85 to $116

million, depending on the tower type, cold water approach temperature, and tube water velocity (which sets the temperature range and flow rate). Capital cost increases as the cold water temperature decreases and the tube water velocity (or flow rate) increases.

Comparable capitalized costs varies from $143 million to $167 million.

2.4.2 ROUND MECHANICAL DRAFT COOLING TOWER SYSTEM Investment, levelized comparable annual and capitalized costs are presented in tabular and curve form in Exhibits 27 and 28.

Investment cost ranges from

$86 to $118 million.

Although these costs are nearly the same as for the

NDCT, RMDCT specifications are more difficult since cold water approach temperatures are 4 F cooler (e.g 8 to 12 F vs 12 to 14 F for the NDCT).

Comparable capitalized cost ranges from $144 to $162 million which is from $5 million lower to $1 higher than the NDCT.

27

2.4.3 ECONOMICALLY PREFERRED COOLING TOWER SPECIFICATION One the basis of low comparable cost, the economically preferred NDCT and RMDCT towers have the following specifications:

NDCT RMDCT Cold approach temperature, F 12 10 Condenser tube velocity, ft/s 5.8 5.2 Condenser range temp, F 20.2 22.6 Cooling Tower flow, gpm 416,200 373,100 Design, performance and cost data for these specific selections are given in the next section.

2.5 COOLING SYSTEM DESIGN, PERFORMANCE AND COST PARAMETERS Cooling tower economically optimized specifications were evaluated by Marley Cooling Tower Company who provided detailed design, performance and cost information (References 6b and 6c).

This information was analyzed to estimate condensing system performance, investment and evaluated costs parameters.

APPENDIX A COMPUTER PIOGRAM FOR COOLING VATEP SYSTEM SIZING AND ECONOMIC EVALTION

A.

INTRODUCTION The input data to the computeizLed optimization program for the selection of a steam condensing system based on costs to comprised of the equipment dosign variables, the heat ratme, layout information, and system load# as well as equipment, material and labor pricing information.

The program, utilizing theee inputs together with mathematical, theoretical and design assumptions, selects and develops cooling system features and components including concrete or earth structures (such as intake structures or cool-ing tower basins), circulating water main and branch conduits, circulating water pwnps and motors (and condenser shells and tubes, If necessary).

The cost Impact of the differential unit transformers' (main, auxiliary and startup) size, which depends an the cooling water system power requirements, ts also considered.

3S COMIUTER PROGRAM The program selects, analyzes and prices all the system components as follows:

(1)

The size of the circulating water pumps, motors and condensers (if necessary) is determined from design formulas and the cost*

calculated based or, the latest pricing lists available assuming reasonable discounts.

(2)

The Intake structurt size Is calculated from general de6ign relation-ships and priced volumetrically ($/cu ft of structure).

(3) Cooling cover data is calculated as a function of approach to the vet bulb temperature and the cooling range based on the input data.

(4)

The optimuw size o. the circulating vater conduits is selected based on a cost analysis of fixed and annual charges (investment and fuel cost)

(5)

The auxiliary power demand and annual energy consumption for the cooling water system are determined from the units loading schedule, circulating water jpump and cooling tower fan design and mode of operation data.

A-1

I (6)

Makeup water consumption and vater treatment chemical cost ts Cal-culated as a function of evaporation rate, drift losses and cycles of concentration in the circulating water circuit.

For each case the economic analysis includes the determination of initial in-vestment cost and annual systemt cost (fixed charges on the investment cost plus the annual operating and maintenance costs).

These costs include items I

related to condenser cooling systems only and do not represent total plant

costs,
1.

Investment Coate The total investment coat consists of estimated major site development cost associated with each alternative cooling system plus computerized variable costs.

The major site development cost, Included in the overall computerized optimization program for each of the alternative cooling systems, is estima-ted based an information shown, on plot plans and the specific quantities required for the following:

Clearing -

general area, Grading - general area, M¢akeup, blowdown system and water treatment -

equipment, piping, structures, Maintenance roads, Condenser tube cleaning system, and Cathodic protection and lighting.

For the cooling pond and spray canal systems, the total civil work cost was included In major site development cost.

Computerized variable Investeent costs are developed by the computer to make up the remaining Investment cost Items which are added to the major site de-velopment cost for the total direct cost of material and installation.

Included in the computerized variable costs are:

Local improvement to sire-clearing, Local grading, Circulating water intakc structure, Spray cooling modules, Circulating water pumps and rotors, Circulating water main and branch water conduits, A-2

I I

Coaling tower basin and superatructure, condenser shells and condenser tubes (if necessary),

Instrumentation and control for circulating water pumps, Unit main power transformer (differential),

Unit auxiliary transformer (differential),

Start-up and stand-by transformer (differential),

Circulating water system svitchgear, and Wiring for circulating water system.

The size and coat of turbine *,

nerstor equipment, pedestal and building for an existing plant is assumed ified for ail cases considered.

Annual Fixed Charges, $/yr Annual Plant end cooling Water System Fuel Coats,

$/yr The total Estimated Investment Cost has been defiued.

7his cost multiplied by an Annual Fixed Charge Rate Is equal to the Annual Fixed CMargeo.

It is assumed that the Nuclear Reactor annual fuel consumption and hence the thermal output is the same for all alternative cooling vater systems. The total plant annual fuel cost tS calculated based on the inte-gral of three (3) periods per year, the percent loading regi-men per period, the thermal rating of the nrIlear reactor and a specified fuel cost.

This cost is the sae for all alternatives. A variable ts the fuel cost related to the cooling water system.

This cost is calculated based on circulating water pump motor and cooling tower fan rotor energy requirements (kWh/yr) and to included In the.com-parable annual system costs.

Description of Cooling S-sutem Water Consumption Water Costs, #/yr Haintenance, $/yr

- Evaporation plus DrIft Loss plus blowdown equals makeup.

- Hakeup x Unit Cost of water treatment.

- A Calculated Cost as a percentage of Investment Cost.

For mchani-cal draft towers$ a maintenance charge per fan is added.

- A st~ation of above costs.

- This cost is based on the above annual costs divided by net annual generation.

- This differential capability cost is calculated at a rate of incre-mental net capability levelized cost times the levelized Fixed Annual Charge Rate times the differential net capability (see next cornt).

- This differential generation cost adjustment it calculated assuming a fixed levelized charge per kWh timS the differential plant net annual generation.

- A S-ms tion of Subtotal Annual Cost and Adjustment.

- This cost is based on Total Com-parable Annual Cost Including Adjustments for Equalized Cap-ability and Generation divided by base net generation, A-6

I l

The above computation Is repested for each condensing system using various values for the water velocity in condenser tubes and cooling tower approach (the latter is defined as the difference between the circulating water temp-erature entering the condenser and the ambient vet bulb temperature).

Then all the cooling system costs are sorted and results printed In ascending order of annual cost with capability and generation adjustment,, the least costly being first on the lint.
