The Kewaunee Power Station (the "Station") is a net 595 megawatt (MW) electric nuclear power station operated by Dominion Energy Kewaunee, Inc. that began operation on December 21, 1973 [one uranium pressurized water reactor (PWR)]. The Station is located adjacent to Lake Michigan nine miles south of the town of Kewaunee, Wisconsin and 27 miles southeast of Green Bay. The oil on site is primarily diesel generator and boiler fuel oil, which are stored in underground tanks plus turbine lube oil in tanks within the Station's turbine building. Only one small aboveground tank is located outdoors (550 gallons). The facility has not experienced a reportable oil spill..

The Station also has some chemicals on site such as sodium hydroxide, sodium hypochlorite, and sulfuric acid for water treatment. Neither oil nor chemical tanks are subject to the direct exposure of stormwater and stationary transfer equipment such as pumps are located indoors. In addition, the majority of Station's oil and chemical equipment has secondary containment. However, small spills outdoors. are possible such as associated with tank truck unloading areas. There is also the potential for larger spills if there was a catastrophic failure of equipment. Both Station stormwater and non-stormwater (e.g.,

industrial and domestic sludge) are regulated by land and water discharge permits.

A topographical map (Figure 1) of the Station is included in Appendix A of this Plan. Appendix B contains oil equipment locations (Figure 2) and chemical equipment locations (Figure 3). Appendix C

• contains a site drainage diagram (Figure 4). Appendix D contains photographs of equipment locations including oil and chemical transfer locations. There is no aboveground piping outside of the Station building. The closest navigable waterway is Lake Michigan; it receives the Station's stormwater runoff.

>WiI-SO67857-.2 PR 1,SCINB (2) (ib). FACILITY~SITE DESCRIPTION AND

~DRAINAGF BkSJ3>MA~P. JSWVPPP PermwiiReference>., 2 The Station's general stormwater "Tier 2" WPDES permit (#WI-S067857-2) requires visual (qualitative) stormwater monitoring on a quarterly basis. The 7 designated storm water outfalls serving both operational and non-operational areas receive storm water via grates or inlets, and ditches throughout the station. The station has two tributaries that run through the station. The tributary south of the station is nick named "Un-named Tributary", which discharges to the Station's waste water Outfall 010. The tributary north of the station is un-named and has a small pond adjacent to Lake Michigan's shore and discharges via conveyance pipe known as storm water outfall 005. Both of the tributaries collect storm water from various areas throughout the station and are monitored at the above discharge locations along Lake Michigan's shore.

The Station also has had an individual wastewater WPDES permit (#WI-0001571-07-0), which permits outfalls (#00 1, 002, 003, and 004), brief descriptions of each outfall is section 3.2.2.

A flow diagram of discharge outfall information is given in Appendix C and described follows:

Storm Water Outfalls (WPDES Permit (#WI-S067857-2):

Discharge Point 005: Is. discharged via conveyance pipe from the pond north of the station, this outfall receives water consist largely of the un-named tributary that traverses the Station's property. As the tributary traverses the station it receives storm water from the approved land applied sludge fields and a storage/parking area. Approximately 90% of the drainage area is grass/covered field and 10% compacted crushed gravel.

Discharge Point 006: Is a ditch that is located north of the station and receives storm water from a narrow drainage area between the plants protected area and the Independent Spent Fuel Storage Installation (ISFSI). Approximately 75% of the drainage area consists of compacted crushed gravel and 25%

concrete.

Discharge Point 007: This outfall is located north of the station and receives storm water from an area that is approximately 50% grass and 50% compacted crushed gravel. The gravel area is currently periodically used to store equipment (ie. scaffolding).

Discharge Point 008: This outfall is located north of the station and receives storm water from an area that is consist approximately of 50% compacted crushed gravel, 40% grass area, and 10% run-off from nearby rooftops.

Discharge Point 009: This outfall is located south of the station and receives 95% of the storm water from a paved parking lot and 5% from the nearby building rooftop.

Discharge Point 010: This outfall receives influents from the sewage treatment facility and discharges to the unnamed tributary, which combines with storm water from the south side of the plant and substation Kewaunee Power Station SWPPP Page 4

Storm Water Pollution Prevention Plan Kewaunee PowerStation April 2009 and discharges to Lake Michigan south of the facility. The effluent of the sewage treatment plant is monitored prior to combining with the southern unnamed tributary.

Discharge Point 011: This outfall is located north of the station and receives storm water from the Independent Spent Fuel Storage Installation (ISFSI) which is an area that is approximately 50% concrete and 50% compacted crushed gravel. The discharge travels from the ISFSI through a storm water collection system and discharges to a sediment diversion pond before being discharged to the shore of Lake Michigan.

Under the Tier 2 WPDES storm water permit provisions, the commingling of non-stormwater with stormwater is not allowed unless the non-stormwater component is regulated under another-permit or unless it is composed of discharges that are not considered illicit by the State of Wisconsin Department of Natural Resources (WDNR). Such allowable discharges include water line flushing, landscape irrigation, diverted stream flows, uncontaminated groundwater infiltration or pumped groundwater, discharges from potable water sources, foundation drains, air conditioning condensation, flows from riparian habitats and wetlands, street wash water, fire fighting water, and minor discharges of fire header dead-leg discharge water. In particular, for purposes of this SWPPP, the non-water sources listed above for Discharge Point 001 are considered by the facility to be allowable non-stormwater discharges because they are included in the Station's wastewater permit.

Non-Storm Water Outfalls (WPDES Permit #WI-0001571-07-0):

Discharge Point 001: Historically, this outfall has received the following non-stormwater tributary flows:

101. Steam generator blowdown and condenser cooling water to Outfall #001 201. Turbine Building sump drainage (floor drains) to Outfall #001 301. Service water treatment lagoon effluent (overflow) to Outfall #001 401. Point 401 was not assigned under permit.

501. Reverse osmosis (RO) unit reject water to Outfall #001 601. Floodwater-pump water (turbine building basement water) to Outfall #001.

Discharge Point 002. Discharge from the Screen House suction point to the vicinity of the water intake to prevent icing over.

A SWPPP evaluation and associated SPCC Plan review has targeted equipment areas where stormwater could potentially be impacted as a result of spills or leaks. The following table gives equipment locations that are the most likely places where stormwater can be impacted. They are primarily associated with storm grate (drip inlet) vicinity to tank truck unloading activities. The likelihood of pollution is low as there is no direct exposure. Refer to Figure 4 in Appendix C for site drainage areas and flow directions.

There are also land areas that could potentially yield pollution from stormwater runoff. These are industrial and domestic sludge spreading areas that may result in stormwater runoff to onsite ponds, woodlands, and wetlands, or stormwater flow directly to the shore of Lake Michigan via area tributaries.

4.4 Site Bulk Oil The oil tank and equipment tables are located in the Station's SPCC Plan in Figure 8 and the associated petroleum transfer/ unloading is discussed in Figure 7, 40CFR 112.7 (h). The SPCC is maintained under separate cover and available upon request.

4.5 Sediment & Erosion 4.5.1 Site Specific Sediment and Erosion Control Most of the Station operating areas are impervious and consist of buildings, concrete, pavement, and/or crushed stone or gravel. There is no evidence of significant erosion and/or loss of sediment in these areas.

Drainage, including sheet flows from these areas, is directed to storm drains (grates or drop inlets).

Stormwater is conveyed to either various land based outfalls, storm water outfalls, or to the station's waste water outfalls.

Also, there are two stormwater retention ponds serving the operating areas. The first is the Training Building, which directs the storm water flow from the rooftops and parking lots to the ditch system that Keivaunee Power Station SWPPP Page 13

Storm Water Pollution Prevention Plan Kewaunee Power Station April 2009 circles that area. This storm water drops its sediment in the retention pond as designed and is then routed to Outfall 005 by surface ditches. The second is found near the Independent Spent Fuel Storage Facility (ISFSI). This retention pond only serves the ISFSI and directs the storm water underground to the pond for sediment removal. The storm water then is directed to the shore of Lake Michigan via Outfall 011.

However, the facility can spread and till sludge as part of land spreading practices on unimproved areas of land to the north and south of the Station operating areas. These are discussed below relative to potential residual pollutant contamination.

To the south, southwest, and northwest of the primary operating areas is unimproved land where there has been land spreading. Service water lagoon sludges including clarifier sludge, ferric hydroxide sludge, Reverse Osmosis Microfiltration Backwash, as well as domestic sludge has been spread and tilled into the soil; these areas can be still be utilized for such activities. Figure 5 in Appendix C shows these areas including stormwater drainage direction, ponds of the area, and ditch tributaries to Lake Michigan that may receive stormwater drainage.

The Army Corps of Engineer placed a retention pond on the shore of Lake Michigan to catch runoff. This pond receives runoff from the largest land spreading area that is to the northwest of the Station. There is an additional pond upgrade and to the south of the Station but it is not believed to receive any runoff from the land spreading areas. Also, at least one drainage tributary receives some runoff from the land spreading areas to the northwest of the Station. For these areas and the areas to the south and southwest of the Station, the likelihood of substantial land runoff of soil resulting in turbidity in Lake water is nil and of no greater likelihood than runoff from neighboring dairy farms. Note that some land spreading area runoff is restricted by recently constructed impervious security wall right of ways.

As mentioned, the Station only has one small outdoor tank. Stormwater accumulation is periodically drained from its dike area after a visual check for oil sheen. Mechanical equipment greater than 55 gallons is limited to nine systems. Emergency Diesel Generators IA & 1B, Main Feedwater Pumps, Turbine Oil Purification System, Pedestal Crane in Containment, Rad Waste Compactor,. Reactor Coolant Pumps, Turbine EH Fluid Reservoir, Turbine oil Reservoir Tank and five elevator hydraulic systems located around the plant, Each oil filled electrical transformer near the turbine building has substantial concrete containment and a drainage sump.

The areas that do not have constructed secondary containment include the Switchyard transformers and breakers, and the tank truck unloading areas for both oil and chemicals. It has been determined that it is not economical and practical to provide containment for the entire substation at this time. Plans are in place to construct oil containment as the substation is being upgraded in the future. Procedures have been changed to require temporary berms for tank truck deliveries of oil. Changes for chemical deliveries procedures are in progress. Finally, the land spreading areas have little if any erosion runoff under industrial wastewater permit land spreading provisions.

Kewaunee Power Station SWPPP Page 15

Storm Water Pollution PreventionPlan Kewaunee Power Station April 2009 5.1 Structural BMPs Refer to Section 4.3 & 4.4 for structural BMPs in place at this Station for both oil and chemicals. Any stormwater that accumulates in secondary containment must be evaluated visually for color, foam, staining, visible sheens, and dry weather flow, prior to release.

5.1.1 Secondary Containment Schedule This facility stores sulfuric acid in excess of threshold limits defined in Section 313 of SARA. Refer to Section 4.3 for secondary containment capacity and the SPCC Plan Figure 12 for the petroleum equipment.

5.2 Non-Structural BMPs In addition to this SWPPP and the Station's SPCC Plan, the Station has operating procedures that are its BMPs including oil and chemical unloading procedures, spill prevention and response procedures, waste disposal procedures, and sludge land spreading procedures.

Storm Water PollutionPrevention Plan Kewaunee Power Station April 2009 5.3 BMP Maintenance Best Management Practices employed for the SWPPP are to be implemented within 24 months of the effective date of the WPDES stormwater permit (7-15-05). This facility has implemented the BMP procedures given in section 5.2.1 of this SWPPP and it updates the BMPs as needed. Preventive Maintenance (PM) of all oil and chemical handling equipment is performed on a periodic basis.

Schedules and written procedures for PM are developed based on manufacturer's recommendations, operator experience, and/or local, state, and federal regulations.

5.4 Existing BMPs Based upon the facility SWPPP evaluation, Section 4.0 (Potential Pollutant Sources) identified those types and locations of equipment that can potential impact stormwater as a result of operational or equipment failure or human error. For the most part, the facility does have both structural and non-structural Best Management Practices (BMPs) that are currently utilized, and will continue to be utilized, until planned feasibility studies are completed for the possible future construction and/or implementation of additional secondary containment. As stated above, the primary concern for potential contamination was associated with fuel oil and chemical tank truck transfer areas subject only to written BMP procedures in areas without secondary containment. Refer also to Section 5.5.

Storm Water Pollution Prevention Plan Kewaunee Power Station Aoril 2009 7.5 Goals & Objectives The stormwater pollution prevention plan (SWPPP) has been developed as required by the Station's stormwater discharge permit and to incorporate good engineering practices. This SWPPP describes this Station, its operations, identifies potential sources of stormwater pollution at the facility, recommends appropriate best management practices (BMPs) or pollution control measures to reduce the discharge of pollutants in stormwater runoff, and provides for periodic review of this SWPPP. It is the objective of this program to improve the quality of surface waters by reducing the amount of pollutants potentially contained in the stormwater runoff being discharged.

ACTION ITEMS Action items are listed in the implementation schedule below. The items are identical to those given in the Station's SPCC Plan. The Station's Environmental Compliance Coordinator shall enter the actual date of completion of each item. Completed action items will be removed from the list at the next SWPPP revision.

Revision to the SWPPP must be completed following the inspection unless permission for a, later date is granted in writing by the State WPDES authority.

3If substantial SWPPP change is necessary including significant modification of existing BMPs or if the addition of new BMPs is necessary, implementation must be completed before the next anticipated storm event, if practicable, but not more than 12 weeks after completion of the comprehensive site evaluation, unless permission for a later date is granted in writing by the State WPDES authority. Refer to the Action Item Schedule on the next page.

The permittee shall amend the SWPPP whenever: (1) there is a change in design, construction, operation, or maintenance at the facility that has a significant effect on the discharge, or the potential for the discharge, of pollutants from the facility; (2) during inspections, monitoring, or investigations by facility personnel or by local, state, or federal officials, it is determined that the SWPPP is ineffective in eliminating or significantly minimizing pollutants from sources identified.

A report summarizing the scope of the inspection, name(s) of personnel making the inspection, date(s) of the inspection, and major observations relating to the implementation of the SWPPP, and actions taken in accordance with the WPDES permit shall be made and retained as part of the SWPPP for at least three years from the date of the inspections.

KPSSystem Descriptiqn . System No. 04 IRev. 5 Title~~Circulating, Water System (C Date MAR 2 0 2008 Page 2 of23 1.0 Summary 1.1 Overview The Circulating Water :(CW) System (See Figure KNP-CWOI) is designed to deliver sufficient screened Lake Michigan water for condenser cooling. ThecCW System intake is designed: to provide a reliable supply of Lake Michigan water regardless: of weather or lake conditions. The CW System Forebay also:.serves as the source for Service Water (SW):System pumps and:the Fire Protection (FP) System pumps.

A 10 foot: diameter pipe carries the Water from the intake to the Screenhouse Forebay. At normal lake level (577 feet), the Forebay: water level. with two CW pumps in operation is 571 feet, and with one CW pump, 574 feet.

The intake structure, Forebay, discharge structure, and Screenhouse are Safety Class 1 structures.

Water is pumped from the Forebay by two vertical CW pumps through: individual check valves ,and discharge pipes. (See Figure KNP-CWO1.) The discharge pipes combine and proceed through a mainconduit until it splits into four individual conduits. ýEach conduit supplies a water box on Condensers A and B. Water flows through the condensers to individual discharge water boxes and out four individual conrduits. These conduits join

.into a common CW discharge tunnel. The common CW discharge receives SW return water and miscellaneous drains. The common CW discharge pipe also supplies water to thexrecirculating water pump for de-icing operations, supplies a chlorine: monitor, and an auxiliary intake line.

The water box priming jet takes a suction on the condenser water boxes to: ensure they are ful of water and do not become air bound.

As depicted, in Figures KNP-CW0.1 :and CW04, two -Turbine Building (Turb. Bldg.)

standpipesi one Auxiliary Building (Aux. Bldg.) standpipe and -a 6"' line from the Demineralizer area drain into the common CW discharge piping. These CW standpipes provide a means of:returning all SW cooling and various system drains/blow-downs to the CW discharge piping.

Various support equipment is provided to assure continuous operation of the: CW System.

A recirculating water pump allows pumping of warm discharge water to a grid of perforated pipes above the: inlets to prevent the formation of ice on the: screen. :Sodium Hypo chlorite injection points are provided for periodic chlorination :into the individual Water boxes and the Forebay. This preventslthe buildup of bacterial slime in the :water boxes:and on condenser tubes and prevents zebra: mussel accumulation in:the:CW system.

.The CW System is required to be placed in operation prior to admitting Startup !steam to the condensers.

Normal full power opeati6oi requiies one: or two CW: pumps and all

• Normal four condenser water boxes in operation. Also, the water box priming Power ejector should be :operating., Low lake water temperature requires recirculating water pump operation to de-ice the inlet crib.

The CW pumps can be.individually shutdown. The discharge chý&k valve allows continued operation of the: other CW pump. If both CW Shutdown pumps are to be shutdown, the, turbine and theReactor can no longer be operated at full power. An extended shutdown requires tuning off the water box priming ejector control.

The CW System maybe hoperated for dilution of plant liquid discharges Refueling during: refueling. However, the:CW System is not specifically required during refueling:operations.

During plant emergency oIperation, only the intake to the Forebay and Casualty the discharge piping from the stop gates to the lake are required for safe:

Events shutdown. Other component failures could cause reduced load operation or a unit trip but do not endanger the safety of the plant.

,n.re.uent Operation without the water box priming: ejector is acceptable, although Operatont the top tubes will notbe flooded and a.:slight increase in turbine exhaust operation_ pressure will result.

A water box: may be removed from service at less than 40 percent load for maintenance activities such as inspecting, cleaning, or tube plugging. Water boxes are. always removed in pairs (1Al and 1B2): or Maintenance (iA2 and 1B1). Onceisolated, the section of condenser tubes and water

boxes are drained. When ready to reflood the tubes and water boxes, the inlet motor operated butterfly valve is throttled open to slowly:.fill

..... ........ .the drained. section.

1.3 Normal (See OP's # N-CW-04, N-CW-04-CL)

The Circulating Water (CW) System is started in accordance with N-CW-04 and N-CW-04-CL. Ifthe system is not already operating, the CW System is placed in operation in

,accordance with N-0.02 prior to:bringing the reactor power to the point of adding heat.

Prior to. starting the CW pumps, ensure the traveling screens are operating and Checklist N-CW-04-CL is complete. Verify that cooling water is available to the CW pump seals and thrust bearing cooling. Check that, all associated: annunciators are clear and that sufficient water level exists in the Forebay. Verify open or throttle open: the condenser inlet valves. Start one CW pump and then open the condenser inlet valves, wide open.

Start: the second CW pump, if required and establish automatic operation of the waterbox priming ejector.

During normal power operations, two CW pumps are inservice for summer operation and one CW pump for: winter, as required to maintain condenser AT or vacuum. Normally, all four condenser: inlet valves are*open. If inlet temperature. is low, commence de-icing the intake crib by starting the recirculating water pump.

When shutting. down the CW pumps or CW System, observe the Precautions of N-CW-04. Stop: the waterbox priming: and recirculating water pump. Stop the CW pumps and close the condenser inlet: valves. Close: the SW supply to the CW pumps: seals and thrust bearing oil coolers.

1.4 Abnormal (See OP #:A-CW-04)

Operating Procedure A-CW'-04 describes automatic and operator actions for abnormal

.conditions Iin the CW System. The symptoms of an abnormal condition are the annunciators associated with the CW System as listed previously in Section 3.0. The immediate actions for an alarm are to silence:the alarm, verify :the problem by checking the SER,: and taking:the necessary action to clear the problem. The abnormal conditions in this. procedure should not cause a plant trip.

1.5 :Emergency (See OP # E-CW-04)

Operating Procedure E-CW-04 describes the: automatic actions, immediate operator actions, and the subsequent actions necessary to recover from a Loss of Circulating Water. A sustained loss of circulating water will result in a turbine trip due to. low condenser vacuum (10" Hg Abs.). In the event of a Turbine trip/Reactor trip, the Operator is directed to perform E-0, entitled "Reactor Trip or Safety Injection".

2.0 Functions The: purpose of the Circulating Water (CW) System is to deliver screened Lake Michigan water to Condensers 1tA and 11B and return this water to the lake. The CW System also provides screened Lake Michigan water to twoý FP pumps and four SW pumps. :SW return: and various drainsý are directed into the CW discharge piping.

Three important functions of the:CWVSystem include the following:

" A reliable source of water to CW, SW, and FP pumps is provided.

• Four traveling screens filter themwater with 3/8 inch mesh to:prevent debris from entering the pump suctions. (See: SystemDescription 02, entitled "Service Water: System'.', for details).

• All plant liquid discharges. are sent through the;CW:discharge for dilution.

Some additional design functions of the CW System include the following:

" Each CW pump is designed to supply 2.10,000 gpm at: a: total differential head of 27.5 feet.:

• Hypochlorite injection. and sample :taps are provided to intermittently inject, sodium hylpochlorite into the individual water boxes and Forebay to: prevent the buildup of bacterial slime in the water boxes and on the Condenser tubes., It also prevents buildup of zebra mussels in the.CW system.

" A recirculating pump provides: warm recirculating water for de-icing the inlet grilles.

Recirculated: water is also directed from the CW discharge to the Forebay to prevent ice.

formation.

- Connections on Condenser lA :inlet water boxes supply CW to the Turbine Basement Cooling System. (Refer to System Description 16, entitled, "Turbine Basement Cooling System", for details.)

IKP System Description System No. 04 . Rev. 5 Title Circulating-Water System CW Date MAR 2 0 200fQ Page 5 of 23 3.0 Design Descriptions 3.1 .System Arrangement and Flowpaths TheCW System (See Figure KNP-CWOI ) takes a: suction from Lake Michigan through a submerged intake structure consisting of three inlet cones-and two auxiliary intakes. A 10 foot diameter steel pipe directs the intake water into the Forebay. The intake water then passes through four traveling screens: to the pump bay in the Screenhouse. The screened water is supplied to the suctions of two CW pumps, four SW pumps, and two FP pumps.

The CW supply is taken from Lake Michigan through a submerged intake structure located approximately 1600 feet from the shore line. The: intake structure has three inlet cones and two auxiliary intakes that are spaced such that the largest lake barge cannot directly cover:all inlets and block water flow. During winter operation, the inlet crib::and auxiliary inlets are below the ice:blanket and are at least 45.0 feet beyond the maximum offshore distance :for ice development.

Water is pumped from the Pump Bay by two vertical dry-pit CW pumps through individual Check Valves CW-lA and CW-lB and discharge pipes. The discharge pipes combine and proceed through a main conduit until it-splits into four individual conduits to supply the water boxes on Condensers A and B. Four motor driven butterfly Valves CW-2A1/MV-32003, CW-2A2/MV-32004, CW-2B1/MV-32005, and CW-2B2/MV-32006, have an expansion joint incorporated into their valve body to allow for thermal expansion. The valves enable water box isolation while at power and are throttled during CW System startup to limit CW pump starting current. CW flows through condenser tubes to individual discharge water boxes and out four individual conduits which join into a common CW discharge tunnel.

The four condenser water box inlets and outlets have connections to the Water Box Priming Jet (See Figure KNP-CW3, CW9). A pipe from each water box vent connection carries a saturated air-water mixture into the discharge pipe. If the vent piping should lose its prime, *the Water Box Priming Jet is set to automatically evacuate any air and reestablish CW flow. A single stage steam jet:air ejector provides the required vacuum in the priming lines. Heating steam is used for the motive force. Control Valves HS-521 and CW-10l are used for priming. The water box priming is used for initial priming of the entire CW System.

Each Condenser water box discharges straight down through a 72 inch pipe and expansion joint to an elbow, into the lower portion of the 120 inch square discharge tunnel. Flow balancing orifices are bolted at the water box outlets of Condenser B to provide equal flow through each section: of the condenser. The common CW discharge receives SW return water and miscellaneous drains (See Figure KNP-CW04).

The common CW discharge pipe also supplies: water to the Recirculating (recirc) Water Pump for de-icing operations (See Figure KNP-CW03). CW flows from the discharge pipe, to a recirculation water deaeration tank, through a recirculation pump, and to the Intake Crib.

An auxiliary intake 30ý inch pipe connects to the CW Discharge Header. This pipe directs warm water back to the Forebay through locked: open butterfly: Valve CW-500.

System (See Figure KNP-CW05) provides air flow to an air bubble, screen at the Intake Structure.: (DCR 2791 abandoned compressor.) Air supply is :provided from the Station Air piping:via manual Valve SA-2l9, if desired.

3.2: Intake Structure and Pipe The CW inlet structure starts With three 22 foot diameter, vertical inlet cones:: whi.ch discharge through 6 foot diameter: outlet pipes to the 120 inch diameter intake conduit.

The cones are located With-their tops one foot above the lake bottom with approximately 15 feet of:normal water depth and approximately 160,0 feet from shore. The inlets have epoxy coated concrete lips to: provide: for a: smooth inlet flow. A steel grid with 2 ft by 2 ft openings and a hinged manway, serves.:as: a trash screen or grille. Plastic covers are

attached to trash screen *grid bars to inhibit frazil ice attaching to the trash screen:and blockingi circulating water flow. The: three cones are reduced to .6 foot: diameter pipes which join at the 10 foot diameter: steel pipe. The 1:20 inch diameter intake conduit is buried aminimum of 3 feet below the. lake floor :to ensure the necessary depth to provide:

the minimum "net: positive suction head": (NPSH) for the CW pumps. The 120 inch diameter: intake: conduit is coated inside and outside with asphaltum and protected by the Cathodic protection system to: minimize corrosion. The velocity at :the surface of :the intakes at full plant load is less than one foot per second (1 fps).

Two 30 inch auxiliary inlets in the top of the 120 inch intake pipe provide auxiliary supplies for Service Water. The two auxiliary inlets are located 50 ft and 100 ft shoreward from the intake cones. Each auxiliary inlet tee rises vertically to one, foot above the lake bottom. :Special screened cover plates are:suspended 12 :inches above the intake:openings to prevent the. entrance of debris. Each auxiliary water intake can: supply in excess of 24,000 gpm. Spacing:of the: three inlet cones and the auxiliary inlets is such that the largest lake barge cannot directly cover all water inlets.

At the inlet to:the Screenhouse Forebay, the 10 foot diameter intake conduit splits into two 100 inch x 120 inch inlets.: A 24 inch line is provided from the Forebay to a 10 foot diameter well, intended for a future fish rearing pond. This pipe is capped and not presently used.,

Forebay level Indication (LI-41551) is provided on Mechanical Vertical Panel "A" in the Control Room. The level control system receives inputs from four level control switches.

If Forebay level decreases to.567.5 ft (approximately 47%), a Forebay Level Low alarm (47051N) is actuated. The Sequence of Events: Recorder (SER) prints out the Forebay Level Low message.

KPS .System Description ISystem No. 04. _ Rev. 5

.Title CirculatingWater System:(CW) IDate MAR 2 0 0--- ;Page 81 of 23._

" If one level switch (1/4) reaches a level of 566 ft (approximately 42%), the same alarm (4705 IN), is actuated, however, the SER Will print the: message Forebay Level Low-Low.

" When 2/4 level switches reach the. 566 ft level, a trip signal is sent to both CW Pumps anda CW Pumps Low-Low Level Trip alarm (4705 1M) and SER are actuated.

This protection is provided to: ensure an adequate supply of water is available, for the Service Water System.

3.6 Turbine. Building Basement: Flooding Trip Turbine Building Basement Flooding Trip (See Figure KNP-CW13)

The Turbine Building Basement Flooding: Trip circuit was installed to detect evidence of significant flooding in the Turbine Building basement thatý could potentially impact: the:

operation of Class 1 equipment at or belowlthe 586' elevation.

The CW pumps receive a trip signal from the turbine building basement flooding

circuitry. The circuitry is designed with two independent trains of detection, and actuation and logic circuitry that Will detect flooding on thelturbine building basement (586' elevation)in the vicinity of the north wall, once the water level equals-or exceeds 3-1/2" 1". The: circuitry will provide a 2 out of 3 logic matrix outputs to trip, both CW pump circuit breakers. Additionally, any single: switch actuation or logic matrix trip actuation will be alarmed in the Control Room to alert the operators of the abnormal conditions. As an earlydetection of flooding in the:basement: an additional detector

[located: 24" (1 i") above condensate pump trench floor] and associated circuitry was installed to provide alarms in the Control Room.

The Turbine Building Basement Flooding: circuitry will actuate three separate alarm windows and their associated:' SERs. The TURB. BLDG. FLOOD LEVEL ALERT alarm Annunciator wiridoW (47052N):and SER will be: actuated when anyone of the, six turbine building basement switches are activated. In addition, eachkbasement switch has a separate SER that can be used to identifywhat level switch was. activated.

Next, the CIRCULATING:WTR PUMPSYFLOOD LEVEL TRIP alarm Annunciator window (47051N) and: SER will be:actuated when anyone of the CW pump breakers receive: a Turbine Building Basement Flooding Trip signal. Each CW pump trip signal :is designed to: generate a SERIsignal that is unique to the tripped CW pump.

Finally, the COND. TRENCH WTR. LEVEL HIGH alarm Annunciator window (47053N) and SER will be actuated when the detector,: located in the condensate pump trench, is actuated.

3.7 Circulating Water Pumps

Two CW pumps are installed. The weight load and thrust of the CW pump is carried by a motor mounted Kingsbury thrust bearing. Pump and motor bearings are oil lubricated and bearing thermocouples are installed.

SWPT from the cartridge filters can be manually aligned if necessary. SW provides an automatic backup. The three gpm minimum seal water flow is measured and alarmedby, a rotometer for each CW pump. A continuous supply of seal water maintains the CW pump packing and throttle bushing free of dirt.

The CW pumps have "Duo-Check" Discharge Valves CW-1A and CW-1BR to prevent water hammer and provide isolation for a nonoperating pump.: Each CW pump has an 8 inch balancing line to equalize impeller back pressure with suction pressure to: reduce

thrust.

The CW motors. space heaters keep the pump ready for starting at all times and to minimize condensation in the motor windings.

CW Pumps A and B are controlled by Switches ES-46507 and ES-46508, respectively, and are located in the Control Room on Mechanical Vertical :Panel. "A". .Each control switch has fourpositions (PULLOUT/STOP/BLANK/START), and spring retums from STOP and START to the blank position. (See Figure KNP-CWi 1.) The PULLOUT and BLANK positions are maintained.

Placing the CW Pump Control Switch ES-46507 or ES-46508 in the STOP position trips the: respective pump motor control breaker which: stops the pump. An. automatic CW pump :trip occurs on a current::overload or a 2/4 Forebay lo-lo level (See: Figure KNP-CW09). After a current overload trip, the Control Room Operator places::the: control switch in the STOP position to reset the circuit: prior to restarting a CW pump.

Indicator lights :are mounted diriectly- above the CW: Pump Control Switch. Red (RUNNING), green.(OFF), and white (OVERLOAD) indicating lights:are provided. An ammeter is also provided for each CW pump.

Each 108 inch CW pump discharge is reduced to 96 inches:and, after Check Valves CW-IA and CW-1B, joins into a common 120 inch pipe which is encased in the basement floor slab. Another 120 inch pipe:joins. the CW common discharge; to provide for a

,possible future cooling tower connection. This: pipe runs to the south end of the screenhouse and is capped. The: 120 inch. CW pump. common discharge line is reduced'to two 96 inch lines:: and then split into four 72 inch vertical water box inlets to the

condensers.

3.8 Condensers Each of the four 72:inch water box inlets contains:a combinationmotor operated butterfly valve/expansion joint. These: MVs control -which water boxes are in service/operation.

MVs CW-2A1, 2A2, 2B1, and 2B2 are normally open. and fail as is. The MVs are

.operated by 1.6 hp motors. The valves are suitable for t.hrottling service: when priming the

Heating Steam Supply Valve HS-521/CV-3 1306 and: Condenser Water Box Priming Control Valve CW-101/CV-3 1304 both cycle to start and stop the priming action.

The controls for this system provide for cycle starting and stopping by either manual or automatic: action. (See Figure KNP-CW09,) Local Control Switch ES-19407 is mounted near the water boxes and, works in conjunction with the mode Selector Switch ES- 19408.

.Switch ES-19407 has four positions (PULLOUT/STOP PRIME/AUTO/START PRIME) and spring returns to AUTO from START PRIME or STOP PRIME., When in automatic operation, the priming: cycle begins when water level in: the water boxes has fallen to the :top of the water box. Priming continues until the water level has reached two

.feet (2') above thc:top of thelwater box in the line from the suction header to the: water box.

Local Switch ES-19408 has three maintained positions (1A NORTHLEITHER(1A SOUTH). This switch is used to: select1 which water box level starts the cycle. The:normal operating mode is the EITHER position. The 1A NORTH position is used when the south condenser half is out of service and vice versa.

Automatic operation is: initiated by DP Switch 1641301, or by 1641401, or by:,either if selected by ES-19408. ýThe initiation sequence is as follows:

The four 72 inch condenser outlets dump into the 120 inch square discharge tunnel, which also receives drainage: and SW returns from the 24 inch Auxiliary Building standpipe and an 18 inch Turbine Building standpipe. Figure KNP-CW04 shows the various drains/inputs to the CW standpipes. The tunnel transitions into a 120 inch

.diameter discharge line. This line accepts drains and SW returns from the Auxiliary Building demineralizer area drains and another Turbine Building standpipe.. The discharge: line provides water. to the recirculating water pump in the Screenhouse. A 120 inch pipe: connection is provided for CW discharge to be routed: to a future cooling tower.

At the 120 inch diameter discharge line outlet, the discharge line: enters the :concrete discharge. structure below lake level. A: concrete baffle in the discharge: structure converts the exit velocity energy to potential energy. The baffle.also spreads the discharge into: the divergent excavated basin. The. near-shore portion of the basin is paved with dumped rip-rap stones and is formed by steel sheet pilings along both sides. The floor of the offshore portion of the basin slopes up: to reach the natural lake bottom.: The excavation extends:to 575 ft IGLD elevation. The warmed :discharge spreads radially from the excavated basin into a mixing zone forming a semicircle in the lake.

Stop: gate slots are provided at the discharge structure and on. either side. of the traveling screens. An isolation gate caný be used to isolate an individual traveling screen, or all screens, or the CW discharge tunnel. These stop. gates:provide the means for isolating portions: of the CW intake: and/or discharge:for inspection or maintenance, A 30 inch recirculating line/ auxiliary intake line connects to the CW discharge in the discharge basin (on :the lake side of: the stop gate: slots). This line is provided to recirculate warm water directly to the traveling, screen. inlet to prevent ice formation. A 30 inch locked open butterfly Valve CW-500 is in the line to the Traveling ýScreen inlet.

Valve CW-500 can be shut to prevent warm water recirculation to the inlet of the traveling screens. This 30-inh re-circulation line will provide enough CW to the forebay to support operation of both SW trains if all other intakes are blocked with frazil ice. A two inch! vent line has been installed to maintain the 30 inch recirculating line full of water. Sufficient heat:is added to CW from SW, for all plant. operating modes above cold shutdown, to maintain the temperature of the water in the CW discharge structure above freezing: during frazil ice conditions.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) / Date OCT 0 4 200I Page 2 of 29 1.0 Summary 1.1 Overview The Service Water (SW) System supplies, water from Lake Michigan for cooling equipment in the steam plant, Containment fan coil units, and Reactor auxiliary systems.

The purpose of the SW System is to provide redundant cooling water supplies for the engineered safeguards equipment required during post-accident conditions and for single non-redundant supplies to other systems, including balance of plant equipment. The SW System utilizes:

• Four pumps with two redundant headers,

• Strainers,

• Isolation valves, and

• Four Traveling Water Screens.

These components are powered from emergency buses, with the exception of Traveling Water Screenss 1A2 and IB I which are powered from non-emergency buses.

The SW System is designed with two redundant headers, each capable of providing for all anticipated post-accident heat removal requirements, including leakage allowances, at the highest expected lake water temperature. Each header is capable of supplying cooling water to balance of plant (BOP) equipment requirements. The SW System is also designed to automatically start the necessary number of. pumps to maintain adequate system pressure.

Various redundant safeguard equipment and coolers are supplied with SW from each Aux Bldg header. Examples of major equipment include: four Containment fan coil units, the Auxiliary Feedwater (AFW) Pumps, and the Component Cooling (CC) water heat exchangers. Some non-safety Class 1 and non-redundant coolers and equipment are-supplied from SW headers. Some examples include the CW Pump seals and bearing coolers, Traveling Water Screen wash nozzles, Fire Protection Jockey Pump, and Spent Fuel Pool Emergency Makeup Valve. The Diesel Generator Cooler Heat Exchanger is supplied by the Main Service Water Header.

1.2 System Operation vs. Plant Mode Plant Mode System Support Startup: The SW System is in operation at all times during plant operation Normal Power: and plant shutdown. The SW System cannot be shutdown while Shutdown: irradiated Reactor fuel is on site. The Control Room Operators must Refueling: refer to KPS TS 3.3e for limiting conditions for operation (LCO's),

yEvents Portions of the SW System are Class 1. Those portions are required CAsuaoy : to be operating for safe shutdown of the Reactor during an accident And Recovery: condition.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) Date OCT 0 4 2007 Page 3 of 29 1.3 Startup (See OP # N-SW-02 & N-SW-02-CL)

The SW System must be operating at all times regardless of plant load. The SW System is operated in accordance with Operations Procedure N-SW-02 under all modes of plant operations. Before Turbine or Reactor startup begins, one SW pump will be running based upon the preferred pump selector switch. For initial startup, a SW pump automatic startup sequence is selected by turning the Service Water Pump Preferred Selector Switch to either SW Pump IA or lB. The discharge Valve of the first SW pump to be started is throttled until discharge pressure has reached approximately 90 psig, then slowly opened.

An additional SW pump is started by holding the control switch to START and the associated red breaker position light goes on. The associated SW strainer is verified operating. The SW PUMP BRG SEAL WTR FLOW LOW annunciator should be verified reset. Prior to starting a SW pump, seal water local pressure indicators should indicate about 10 psig (only this low when on SW backup) as regulated by the pressure reducing valves. The remaining SW Pump control switches are placed in AUTO. During the plant startup, SW Header pressure should be observed to assure that standby pumps start as required to maintain adequate pressure. With Station and Instrument Air System in service and air pressure at least 70 psig, SW System startup can continue.

The bubbler system in the Screenhouse for Traveling Water Screens DP signals is started.

Before a Traveling Water Screens is placed in service, Spray Water Isolating Valves SW-201A1, SW-201A2, SW-201B1 and SW-201B2 and Root Valves SW-200A and SW-200B must be checked to determine if they are open. The cleaning cycle is manually started, and screen operation is observed. After the screens have cycled several times at the high speed, the mode select switches are reset to AUTO. All doors and housing must be firmly in place and latched.

The SW System valves are normally aligned as follows:

• Both Header Isolation Control Valves SW-3A and SW-3B are open.

• Both Aux Bldg Header Control Valves SW-IOA and SW-0OB are open.

& Both Aux Bldg Header Manual Isolation Valves SW-1 1A and SW- 11B are closed.

& Turb Bldg Header Control Valve SW-4A or 4B is open.

• SW Supply and Return Valves to each component in the plant are open as required (Prestart Checklist N-SW-02-CL).

During plant startup, SW usage is regulated by the needs of plant systems. Pump minimum flow requirements of 1800 gpm is maintained by placing the associated strainer backwash in operation in accordance with Operations Procedure N-SW-02, if necessary.

1.4 Normal (See OP # N-SW-02)

SW System capability to provide plant required SW flow is automatically controlled. SW pumps start automatically to maintain pressure. Traveling Water Screens and SW strainers remove debris from the SW and automatically clean themselves. Control Room indication provides verification. Normally, SW pressure is maintained between 90 to 100 psig by manually starting/stopping SW pumps.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) Date 10 4 Z007 Page 4 of 29 Normal SW pump operation includes semimonthly switching of running equipment to even pump wear and to assure availability of pumps at all times. Pump shifting is accomplished as follows:

1. Position Service Water Pump Preferred Selector to new position

2. START the second pump in the header matching the Service Water Pump Preferred Selector position.

3. Position Turbine Building SW Header Selector to the header matching the Service Water Pump Preferred Selector position NOTE: Allow A and B Service Water Header pressures to stabilize prior to stopping pumps.

4. STOP the required pump(s).

Normal SW system operation includes changing the Turb Bldg SW Header Control Valve position bimonthly. This switching is accomplished manually by turning Control Switch ES-46516 to either Turbine Building SW Header Isolation Valve SW-4A or B position. The Operator checks that, except during switching, only one valve shows a red (OPEN) position indicating light. Isolation Valves SW- 1A and SW-1IB are normally OPEN during refueling (Cold Shutdown).

When changing the equipment lineups semimonthly, the seal water supply from the Plant Equipment Water/SWPT System to each pump is valved out for approximately five (5) minutes. This action verifies that the self contained seal water (Cuno) filters maintain seal flow. The filters are replaced if necessary.

1.5 Abnormal (See OP# A-SW-02)

An abnormal condition in the SW System is indicated by alarms in the Control Room and SER printouts. The Operator needs to identify the specific problem from the symptoms/indications and to take appropriate corrective action in accordance with Operations Procedure A-SW-02. Some automatic actions which occur include:

" Upon receiving a High Traveling Water Screens DP, the screens start screen washing and running in fast speed until the high DP signal is cleared for 9 minutes.

" Upon receiving a SW Discharge Strainer high DP alarm, the affected strainer starts backwashing and continues for 3 minutes after the alarm has cleared.

In the event of a Traveling Water Screens High DP, the Operators observe the screen lights on the Mechanical Vertical Panel "A" and dispatch an Equipment Operator (EO) to the Screenhouse to check Traveling Water Screens and the Trash Basket for debris. The EO turns the local mode selector switch to HAND for the affected screens if the automatic running and washing has not occurred.

If a leak is suspected in the Containment Cooling SW Header, the Operator should attempt to diagnose the leak location. If circumstances permit, a Containment entry should be made. If the CRDM Shroud Cooling Coil is suspect, the Operator should switch the CRDM Shroud Cooling Coil Headers.

• If the leak continues the CRDM Shroud Cooling Coil selection switch should be placed in PULLOUT.

" If the leak continues, SW Inlet Valves SW-900A, SW-900B, SW-900C or SW-900D should be closed sequentially to locate the leak.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) Date OCT 04 2007 Page 5 of 29 The SW Return Valves SW-903A, SW-903B, SW-903C or SW-903D should be closed to isolate the affected header. (TS 3.3.C.1 would be referred to for the required number of operable Containment Fan Coil Units for the existing plant mode of operation.)

In the event of Turb Bldg Header SW Isolation Valve closing, the Operators observe valve indication, attempt to open at least one valve and check that Instrument Air is being supplied to the Turb Bldg Header Supply Valves. If neither Turb Bldg Supply Valve can be opened, trip the turbine and follow E-0. Equipment supplied by the header should be secured.

For SW Pump Seal Water Flow Low, Operators observe the SER printout to determine which pump is affected and start a standby pump if necessary. For SW Pump Strainer High DP an EO is sent to the Screenhouse to investigate. The EO must locally start backwashing if the system has failed to start in AUTO.

In subsequent action steps, the Operator ensures that the plant conditions have stabilized and restores SW equipment to operating status. In all cases, the Operators ensure that equipment alignment and operation are in accordance with TS 3.3.e.

1.6 Emergency (See OP # E-SW-02)

During plant emergency operation, SW is supplied to at least one train of safeguards equipment. The SW System responds to a SI actuation, sequential DG loading, and low SW Header pressure by closing Isolation Valves SW-3A and SW-3B to form two redundant headers. SW Pumps are started in a pre-selected sequence. Since adequate SW is available with two pumps supplying one header to provide all Class I and balance of plant requirements, the Turb Bldg Header is not automatically isolated, unless a low SW header pressure condition exists in conjunction with a Safety Injection (SI) signal.

During normal operation, failure of a pipe or valve results in automatic Turb. Bldg.

Header isolation. Operator action may be required to maintain Turb Bldg Header supply in the event of failure on the header supplying the Turb Bldg at that time. Emergency Procedure E-SW-02 outlines the steps necessary to ensure SW is supplied to at least one train of safeguards when low pressure exists. Both "SI" and "Low SW Header Pressure" conditions must exist before Valves SW-4A and/or SW-4B automatically goes CLOSED.

Automatic actions that occur on a dropping pressure indication automatically start pumps in a pre-selected sequence. If either header pressure drops to 72 psig, these additional actions occur:

" If Header 1A pressure is less than 72 psig, both pumps, (lAI and 1A2) receive START signals and the Header Isolation Valve SW-3A closes.

• If Header 1B pressure is less than 72 psig, both pumps, (1B1 and 1B2) receive START signals and the Header Isolation Valve SW-3B closes.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) Date OCT 0 4 2007 Page 6 of 29 The Turb Bldg supply should always be shifted to the header with the higher pressure. If the pressure starts to drop in the Turb Bldg Header and the leak cannot be isolated locally, the Operators trip the turbine and perform E-0, "Reactor Trip or Safety Injection". The remaining steps require isolation and securing of equipment to isolate the leak. Alternate cooling may be required for certain equipment.

Note: Throughout the subsequent actions, the Emergency Plan Implementing Procedures (EPIP) should be reviewed to evaluate if the emergency response organization should be activated.

2.0 Functions The purpose of the SW System is to provide redundant cooling water supplies for the engineered safeguards equipment required during post-accident conditions and for single non-redundant supplies to other systems, including balance of plant (BOP) equipment.

The SW System is designed with two redundant headers. Each header is capable of providing all anticipated post-accident heat removal requirements, including leakage allowances, at the highest expected lake water temperature. The SW System is adequate fdr supplying cooling loads of the BOP equipment as well as for meeting the maximum operating and post-accident Safety Class I equipment requirements.

The Safety Class 1 SW supply is designed to function following one active (operational) failure within the system. The large SW return lines within Safety Class 1 areas are designed as Safety Class 1 since breaks in these lines could cause flooding of Engineered Safety Equipment (ESF).

Various equipment in the SW System is powered from the emergency buses. This equipment includes the SW pumps, isolation valves, and two Traveling Water Screens.

The SW System functions as an emergency makeup supply to the following equipment:

• AFW pumps if the Condensate Storage Tank fails for any reason.

• Spent Fuel Pool (SPF)

• CC Surge Tank The SW System is designed to automatically operate the necessary number of SW pumps to maintain adequate system pressure. The SW System is designed to supply the designed flow rates to the various equipment. The SW System was originally designed to provide a pressure greater than the peak pressure expected during a LOCA at the Containment Fan Coil inlet penetration to prevent leakage from Containment to SW System in case of fan coil piping breaks.

However, the pressure at certain points has been analyzed to be below the Containment design pressure of 46 psig. Since the fan coils and service water lines form a closed system inside the Containment, no contaminated leakage is expected into these units. Should such an unlikely situation occur, the unit could be remotely isolated to prevent outleakage.

KPS System Description . System No. 02, Rev. 4 Title Service Water System (SW) Date OCT 0 4 2 nz Page 7 of 29 3.0 Design Descriptions 3.1 System Arrangement and Flowpaths SW And CW Intake System The SW System takes a suction from Lake Michigan through a submerged multiple intake structure from Lake Michigan consisting of three inlet cones.

Note: Two auxiliary inlets are provided on the intake conduit downstream of the multiple inlet.

This alternate source of lake water is capable of providing all SW requirements if the normal intake structure becomes damaged or blocked.

Note: In addition, another alternate source of SW is provided by an interconnecting pipe between the CW discharge structure and the Screenhouse Forebay. This interconnection provides a redundant source of SW in the unlikely event the main intake line becomes blocked A 10 foot diameter steel pipe directs the intake water into the Forebay of the enclosed Screenhouse structure. The water passes through four Traveling Water Screens to the pump bay in the Screenhouse. The screened water is supplied to the suctions of the four SW pumps and the two CW pumps. (Two fire pumps also take a suction from the pump bay.)

The SW and CW intake system is designed to Safety Class 1 requirements.

The SW System supply to the suction of the AFW pumps is Safety Class 1.

SW Pumps - SW is pumped from the pump bay by four centrifugal SW pumps through alternate individual check valves, rotating strainers and manual butterfly isolation valves.

Each SW pump is capable of supplying 6400 gpm and is powered from one of two 4160 Volt emergency buses. Each pump discharges through a check valve to a rotating strainer and manual butterfly isolation valve. Two SW pumps (1A1 and 1A2) discharge to SW Header A and two SW pumps (IB1 and 1B2) discharge to SW Header B.

SW Headers - The two SW headers are connected at the pumps by two normally open, remotely operated butterfly valves (SW-3A and SW-3B). These valves separate the headers when necessary. Each SW header supplies water to an Auxiliary Building (Aux.

Bldg.) through motor operated butterfly isolation valves (SW-10A and SW-lOB) respectively. These two Aux. Bldg. headers can be connected together in the Aux. Bldg.

through two normally closed manual butterfly valves (SW-i 1A and SW-1IB). To ensure train separation, this is normally done when the plant is in cold shutdown. Various redundant safeguard equipment and coolers are supplied with SW from each of these headers.

Turbine Building - The Turbine Building (Turb. Bldg.).SW line is supplied through two remotely operated butterfly valves (SW-4A and SW-4B). Only one valve is open at a time to supply SW to the Turb. Bldg. Valves SW-4A and SW-4B have air accumulators to allow closing the valves on loss of normal air. Examples of loads on the Turb Bldg Header include the Main Feedwater Pump (FW) oil coolers, Turbine Lube Oil Coolers, Seal Oil Unit Oil Coolers, generator hydrogen coolers, and the Condensate Pump beating coolers.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) Date OCT 0 4 2007 Page 8 of 29 During an SI or low SW header pressure condition, SW headers A and B are automatically isolated by closing the separation valves (SW-3A and SW-3B). At the same time, all four SW pumps and rotating strainers start.

A Safety Injection , coincident with Low SW Header Pressure, will isolate the Turb.

Bldg. SW Headers by automatically closing Valves SW-4A and SW-4B. (DCR 3338)

All SW Return headers dump into the CW System discharge. The discharge consists of three standpipes:

• Aux Bldg Standpipe - 24",

• Turb Bldg Standpipe - 24",

• Turb Bldg Standpipe - 18".

The SW Return paths are separated to minimize the possibility of flooding problems if a return line fails. SW Returns are directed to the CW System discharge.

Isolation valves are provided to isolate sections of the SW System in the event of a system malfunction. The Operator can isolate portions of the Aux. Bldg and the entire Turb Bldg SW supply by closing remotely actuated isolation valves.

Aux. Bldg. (portions of) I SW-10A & B Turb. Bldg. (entire) SW-4A & B Rad Monitoring - The Aux Bldg Standpipe is monitored by Radiation Monitors R16 and R-20.

3.2 Service Water Pumps 3.2.1 Service Water Pump Design Four Worthington Corporation vertical, wet pit, single-stage, double suction, water lubricated, 1750 rpm, centrifugal pumps are installed in the pump bay for supplying SW to the Plant. The small weight load of the balanced thrust, dual volute impeller and shaft is supported by the vertical solid shaft Allis-Chalmers motor. Both motor upper thrust and lower line ball bearings are provided with oil thermocouples. for computer inputs. The pump bearings are leaded bronze and the shaft is stainless steel.

Both the SW pump casing and the pump impeller have wear rings installed to ensure the pump maintains capacity for a longer period of time. The pump impellers each have 13% chrome wear rings and the pump casing have 17%

chrome wear rings (per DCRI 106). The original bronze casing and impeller hubs had shown severe sand erosion. The chrome wear rings will withstand the erosion for a longer time and maintain pump capacity.

KPS System Description System No. 02 Rev. 4 Title Service Water System (SW) Date OCT 0 4 2007 Page 9 of 29 Bearing water flow must be provided to keep the bearings free of dirt, and to lubricate the shaft tube bearings. The normal seal water supply is provided by the Plant Equipment Water Pumps. SW Pretreatment can be manually aligned in the event Plant Equipment Water is removed from service. 10 microns, dual element Cuno filters have been added to each of the normal seal water supply lines (one for each SW pump) to provide a final filtering of this water supply. (DCR3695)

Automatic backup seal water is taken from the SW Strainer outlet and filtered to 10 microns in a Cuno dual element filter. Backup seal flow is regulated by a pressure regulator with flow metered and alarmed at 0.5 gpm minimum by a Rotometer. Minimum flow in a non-running pump is 0.5 gpm. Expected flow to a running pump is about 1.25 gpm.

Each SW pump has a discharge check valve (SW-1A1, SW-1A2, SW-IB1 and SW-1B2). The check valve allows starting with an open discharge valve and prevents reverse rotation when the pump is not operating. Reverse pump rotation could loosen shaft couplings and cause improper impeller alignments. The SW pump discharge "column pipe" upper section is provided with eight stiffening ribs for strength required by seismic design. Each pump discharge is provided with a pressure gauge. Each SW pump motor has a space heater to keep the standby pump ready for immediate start.

The SW requirements during any operational condition are normally met by two to four SW pumps. Under normal conditions, a pressure sequencing system adds additional SW pumps to the running complement as the flow requirements increase. Two different pump sequences are available. The desired sequence is selected by the operation of the Control Room Selector Switch ES-46523. This switch is a two position maintained device (1A/IB) located on the Mechanical Vertical Panel "A".

PUMP SEQUENCE 1A PUMP SEQUENCE 1B Pump Press Switch Setpoint Pump Press Switch Setpoint 1A1 none Continuous 11B2 None continuous 1A2 PS-16005 86 psig lB1 PS-16005 86 psig 1B1 PS-16003 82 psig 1A2 PS-16003 82 psig

The third pump starts if SW Header A pressure is less than 82 psig. The fourth SW pump automatically starts if pressure in Header B is less than 78 psig. Normal SW pump discharge pressure is90-100 psig.

3.2.3 Normal SW Pump Control (See Figure KNP-SW04)

The control logic for each SW pump is almost identical. The following description is applicable to any SW pump. Each pump has a Control Room switch located on Mechanical Vertical Panel "A". The Control Room switch has four positions (PULLOUT/STOP/AUTO/START). The switch spring returns to AUTO from START or STOP positions.

These two positions are dominant and prevent the operation of the SW pump regardless of the presence of any automatic start signals.

Note: The Operator must hold the switch in the STOP position to prevent operation.

In addition, these positions provide a reset signal to the breaker lock-out circuit.

This lock-out feature prevents an automatic restart of the SW pump after a breaker overcurrent condition. After the overcurrent condition, the appropriate SW pump switch must be rotated to the STOP position prior to restarting.

KPS System Description System.No. 02 Rev. 4 Title Service Water System (SW) Date UG 0 4 2007 Page 11 of 29 When one of the Control Room switches are in the AUTO position, the associated SW pump starts in a response to a pressure control sequence signal, if the following conditions are satisfied:

• Seal water flow is adequate (greater than 0.25 gpm on associated flow switch).

• Automatic operation is not inhibited (no SI or Blackout sequence).

• Pump has not tripped due to an overcurrent condition.

Once the SW pump has started, it continues to run until the Operator tunis the pump off with the control switch or until a load shed signal is received. A load shed signal exists for a short period just prior to the start of a SI or Blackout sequence.

When the control switch is placed in the start position, the SW pump immediately starts if the seal water flow is adequate. If the seal water flow is too low and the Operator holds the switch in the START position, for 5 seconds, the seal flow interlock is bypassed and the pump will start. Once the pump has started, it continues to run until one of the previously mentioned trips stops the pump.

The SW pumps each have red (RUNNING) and green (OFF) indicating lights, located with the Control Room switches. White status lights are also provided for each SW pump in the Safety Injection Active Status Light Panel on Mechanical Vertical Panel "C". SW Pumps 1Al and 1A2 also have control switches with red (RUNNING) and green (OFF) indicating lights on the Dedicated Shutdown Panel (DSP).

3.2.4 Abnormal SW Pump Operation Abnormal SW pump operation is discussed for three different conditions:

• Low SW Header pressure SSI sequence

• Blackout sequence If the SW pump control switch is in the AUTO position, the SW pump on the affected header starts upon receipt of a very low SW Header pressure signal (less than 72 psig), provided an automatic operation inhibit signal is not present. The very low header pressure signal overrides the seal water flow interlock. The SW pump starts and runs even if there is low or no seal water flow. The SW pump continues to run until stopped by the Control Switch (i.e., Load Shed Signal).

If the control switch is in the AUTO position when a SI or Blackout sequence signal is received, the SW Pump starts and runs. The seal flow interlock is again overridden, for these starts.

Note: A Blackout sequence only starts SW Pump 1A2 and 1B2.

KPS System Description ,System No. 02 Rev. 4 Title Service Water System (SW) Date OCT 0 4 2 n7 Page 12 of 29 In any of the above abnormal conditions, the PULLOUT and STOP positions are dominant. These positions prevent or stop pump operation. These switch positions also provide a signal for reset from a current overload trip condition. The current overload is also dominant over any automatic signal. During abnormal or emergency conditions, the Operator is able to manually start the SW pump at any time, if power is available.

3.3 Traveling Water Screens Four Traveling Water Screens are divided into two pairs (lAl and 1A2) (iB1 and 1B2).

From the forebay, water passes through four 10 foot wide by 36 foot long Traveling Water Screens with a mesh size of 3/8 inch. Each Traveling Water Screen is capable of passing 110,000 gpm. A single local control panel for both pairs of screens provides both manual and automatic control. Auto control consists of high differential pressure (DP) operation at high speed and long time duration operation at low speed.

The flushing controls provide automatic backwashing set on a four hour timer. A high DP of 6 inches of water starts the Traveling Water Screens in fast speed and flushes for nine minutes after the high signal (alarm) clears. If no high DP occurs within four hours, the screen sprays and motor drives are operated for 45 minutes at low Traveling Water Screens speed. This operation lubricates the gear box components and articulates the drive chains to prevent seizure during long periods when no debris is present in the intake structure. Traveling Water Screens pressure switches are provided to determine screen SW Supply pressure. Greater than 60 psig interlock, as measured by the Traveling Water Screens pressure switches, is required for starting the screen motor.

The Traveling Water Screen housings have been reinforced to protect the Screenhouse from flooding during a maximum seiche (lake water level build-up resulting from meteorological conditions). The inspection doors should remain latched except during inspections.

DP Switch (6") . 1642501 1642501 1642601 1642601 The control logic for the Traveling Water Screens is separated into two identical circuits (1AI/1A2 and 1B1/1B2). (Refer to Figure KNP-SW05 for the following discussion.)

A local screen wash panel contains three switches for each of the two control circuits.

One of the switches is a three position maintained device (HAND/OFF/AUTO). The other two switches are two positioned (OFF/ON) maintained devices, located in back of the panel. The OFF/ON switches are used to electrically isolate a particular Traveling Water Screens solenoid valve to prevent operation while the remainder of the control circuit remains operable. In addition, test pushbuttons are provided to test the screen drive motors. The pushbuttons are located next to the Traveling Water Screens.

With the three position switch in the OFF position, the automatic wash solenoid valves remain closed, thus preventing backwash. With the three position switch in this position the screen motors do not operate unless the local pushbutton is pressed and held. In this mode of operation the screens run at low speed.

When the local three position control switch is placed in the HAND position, both solenoid water valves open. As SW pressure in the spray nozzle header increases above the respective Traveling Water Screens pressure switch setpoint (60 psig), the associated Traveling Water Screens starts and runs at high speed.

When the control switch is placed in AUTO, a high DP across the screens automatically opens the backwash solenoid valves. If SW pressure in the spray nozzle header is above 60 psig, the Traveling Water Screens start and run at high speed. The screen is run at high speed for 9 minutes, after the DP switch has been reduced below the high setpoint (6 inches DP).

A special circuit is provided to operate the screen wash valves, which results in operation of the Traveling Water Screens for 45 minutes on a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> cycle.

A single 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> cycle timer controls the exercise cycles for both control circuits. The timer is adjusted so that only one set of screens are operated in the exercise mode at any time.

If a high DP develops during an exercise cycle, the automatic backwash cycle immediately starts. As described above, the screens operate at high speed. and the screen wash valves open. During the auto cycle, the four I

hour timer continues to run.

KPS System Description , System No. 02 Rev. 4 Title Service Water System (SW) Date IP.T 0 4 Page 14 of 29 If any exercise time is left at the end of the auto cycle, the Traveling Water Screens automatically return to the exercise cycle mode of operation.

Screen red (RUN) lights are provided on the local panel. In addition, the local panel contains a power on light for each control circuit. On the Control Room Mechanical Vertical Panel "A", one set of screen red (RUN) and green (OFF) lights is provided for each control circuit. The red (RUN) light is on if either screen motor is running. The green (OFF) light is lit if both screen motors are stopped. The backwash solenoid valves fail closed on a loss of electrical power supply.

3.4 Service Water Strainers (See Figures KNP-SW04 and KNP-SW07)

Four Kinney rotating, single drum, multiple basket media, automatic backwash strainers are installed on the discharges of the SW pumps. Each strainer has a motor drive unit to rotate the strainer constantly whenever the associated SW pump is operating. A packing and gland assembly seals the drive shaft against leakage. The strainer has dual backwash slots to balance thrust during backwashing. Backwash valves are operated by pneumatic cylinders. A DP of 5 psid across the strainer causes the individual backwash valve to open and discharge to the trash trough NOTE: D/P alarms at 8 psid. Full system pressure is applied across each strainer element for 3 minutes as it passes the backwash slots on opposite sides of the strainer. Backwash water is strained in a basket assembly at the trash trough outlet and then the water drains to the CW discharge through an 18 inch line.

Manual operation is provided for by an exposed valve shaft extension. Field adjustment of valve rotation is required to limit backwash flow rate to an acceptable amount. Additionally, provisions are made for manual drum rotation. The individual media baskets are replaceable.

Each rotating strainer drive motor has a local control switch. The switch has two maintained positions HAND/AUTO. In the .AUTO position, the strainer rotation is controlled by an auxiliary contact on the associated. SW pump motor electrical breaker.

Thus with the switch in the AUTO position, the strainer rotates while the associated SW pump is running and the strainer stops when the pump stops. With thelocal switch in the HAND position, the strainer rotates continuously.

(See Figure KNP-SW07). A local control panel is provided. The panel contains the indicating lights and two control switches for the control of each strainer backwash. The indicating lamps show red (OPEN) and green (CLOSED) position of the strainer backwash control valves.

One of the two switches is a three position maintained device (AUTO/OFF/HAND). The second switch is a two position maintained device (CLOSE/OPEN). In addition, each strainer is provided with a DP switch. As indicated in the following paragraphs, the DP switch provides the automatic input signal for the strainer backwash.

When the local panel three position switch is in the AUTO position, strainer backwash is automatically initiated when the DP across the strainer reaches 5 psig. The backwash is continued for 3 minutes after the DP falls below the setpoint. The extended backwash time ensures effective cleaning of the strainer. This extended period is controlled by adjustment of a time delay located in the local panel. One time delay is provided for each strainer.

When the local panel three position switch is placed in the HAND position, the local two position switch is used to manually control backwash. Backwash takes place when the two position switch is in the OPEN position. Backwash is stopped when the switch is turned to the CLOSE position. With the three position switch in the HAND position, automatic backwash is inoperable. With local three position switch in OFF position, the backwash valve remains closed, thus preventing backwashing. The logic and components for the strainer backwash are selected so the backwash fails "as is" on an electrical and/or air supply failure.

Each valve is controlled by a three position switch (CLOSE/AUTO/OPEN). The switches spring return to AUTO. The switches are located on the Control Room Mechanical Vertical Panel "A". A set of position indicating lights, red (OPEN) and green (CLOSE), are provided with the control switch.

SW Header Isolation Valve SW-3A can also be operated from the Dedicated Shutdown Panel (DSP). If the LOCAL/REMOTE switch is placed in LOCAL, the Control Room switch and indicating lights are disabled. The local control switch at the DSP is now operable and the associated lights indicate the position of Valve SW-3A.

3.6.2 Aux Bldg SW Header Isolation Valves One motor operated butterfly valve (SW-10A, B) is provided for each Aux Bldg SW header. These two 16 inch valves provide for remote isolation if flooding occurs or in the event of a failure in the Containment fan coil SW piping. Valve SW-10A is powered from MCC 1-52A and Valve SW-10B from MCC 1-62A.

There is no auto closure provision. Valve SW-10A is located in DG Room A.

Valve SW-10B is located outside DG Room B.

In case of malfunction of one of these valves or loss of a 24 inch SW header, the other Aux Bldg SW header supplies all Safety Class I systems necessary for safe plant operation. Two manual gate valves (SW-I 1A and SW- 11B) are provided to connect the Aux Bldg SW headers. These valves allow all Safety Class I equipment to be supplied from one SW header if necessary.

DSP Control Switch ES-87121 is a two position maintained switch (CLOSE/OPEN). Control Room Switch ES-46554 for Valve SW-10A is a 3 position spring return from left or right to center switch (CLOSE/BLANK/OPEN).

3.6.3 Turbine Building SW Header Control Valves One SW header supplies the Turb Bldg equipment. In order to supply this header from either SW train, two 20 inch air operated butterfly valves (SW-4A and SW-4B) are provided. Normal operation requires that only one valve be open at a time. Automatic sequencing allows transfer of supply from one header to the other. Upon SW header isolation, each Turb Bldg SW header control valve remains as is. Operator action is required to close the open valve.

However, upon both "SI Sequence - Step 9" and "Low SW Header Pressure" (82.5 psig) conditions, the open Turbine Bldg SW Header Control Valve will automatically close, and both Valves SW-4A and SW-4B will be blocked from manually re-opening, until the SW Header pressure is restored and the Turbine Bldg Service Water Isolation signal is reset. Per DCR 3338

When the control switch is in the ISOLATE position, both control valves remain in the closed position. When the switch is turned to the SW Header IA position, the valve between SW Header 1A and the Turb Bldg opens. If the valve between SW Header 1B and the Turb Bldg is open, it automatically closes after the Control Valve IA is fully open. In a similar manner, when the control switch is turned to the SW Header 1B position, Valve SW-4B between SW Header 1B and

The Containment fan coil unit SW return valves control the flow of SW through the fan coil coolers. These valves provide cooling during normal operation, and if closed, they are automatically opened during abnormal conditions. Due to the redundancy requirements imposed for abnormal conditions, the valve logic is divided into two trains according to the SW header to which the va'lves are connected. Each train logic contains three valves.

Each motor operated valve (MOV) has a three position (CLOSE/AUTO/OPEN) spring return to AUTO switch. The control switches are located adjacent to the associated Containment fan coil motor control switches on Mechanical Vertical Panel "A". Limit switch actuated valve position lights are provided directly above each switch. The air operated valves are modulated from a control station which is found in the same location.

The MOV's fail "as is " on loss of electrical supply. The air operated control valves fail closed on loss of electrical and/or air supplies.

Under nonnal operating conditions, MOV's are used as a coarse Containment temperature control. A closed loop analog control is used to provide position and hence flow control for both of the normally CLOSED air operated control valves.

Each air operated control valve is also controlled by a three way solenoid valve.

This solenoid valve maintains the control valve in a closed position if either of the following conditions exists:

" The MOV in parallel with the control valve is not fully closed.

, The associated Containment fan coil cooler fan motor is not running.

During abnormal conditions, a SI sequence signal is used to automatically drive all MOV's fully open. The air operated valve in parallel with the MOV closes automatically when the MOV leaves the fully closed position.

KPS System Description System No. 02 . Rev. 4 Title Service Water System(SW) Date UCT 0 4 ZUOI Page 20 of 29 The Containment Fan Coil SW Return Valves (SW-903A and SW-903B) can also be operated from the DSP, similar to Valves SW-3A, SW-4A and SW-1OA. When the associated LOCAL/REMOTE switch is in the LOCAL position, the indication and valve control is switched to the DSP.

3.6.5 SW to Component Cooling (CC) Heat Exchangers 1A and 1B (See Figures KNP-SW03 and KNP-SW06)

The control of SW flow to each CC Water Heat Exchanger is similar. The following description is applicable to both heat exchangers. The numbers in the text are specifically for Heat Exchanger IA, but refer to the Table for valve and switch numbers for CC Heat Exchanger lB.

MV-32010 Motor Control Switch ES-46553 ES-46552 Motor Valve Power Source MCC 1-52B MCC 1-62E SW flow to CC Heat Exchanger 1A is normally controlled by an air operated control valve (SW-1306A/CV-31046). This fail open valve is controlled by a temperature controller (TC-26309). When the temperature of CC water leaving the heat exchanger increases above the setpoint (90-1000 F), Valve SW-1306A opens. When the temperature decreases below the setpoint, Valve SW-1306A closes. This valve also is provided with valve position indicating lights in the Control Room.

During abnormal operation, Valve SW-1300A/MV-32009 is opened to allow more SW flow through CC Heat Exchanger 1A. The abnormal operation is during periods of high heat load such as RHR or Containment Sump Recirc operation.

SW-1300A may be throttled OPEN during periods of high heat load to allow SW-1306A to control temperature of the Component Cooling water system within its control band.

SW-1300A is operated from the Control Room by Control Switch ES-46553. This switch is a two position (CLOSE/OPEN) spring return to CENTER switch. The valve has red (OPEN) and green (CLOSE) indicating lights located with the control switch.

In the event of an SI at sequence step 0 the SW-1306A/B will go to full OPEN.

After SI is reset and automatic control of CC water temperature is desired the SW-1306A/B valves must be reset locally using the local push button.

Valve limit switches provide inputs for valve position indicating lights red (OPEN) and green (CLOSE) which are located with the associated control switches. The MOV's are equipped with a mechanical override for manual emergency operation.

3.6.8 SW to Spent Fuel Pool (SFP) Emergency Makeup (See Figure KNP-SW03)

One manually operated valve (SW-1497) is provided as emergency makeup to the SFP if normal Reactor Makeup Water is insufficient or is not available.

3.6.9 Spent Fuel Pool Heat Exchanger SW Valves Service Water flow through the SFP Heat Exchanger is modulated to maintain a controlled temperature in the SFP. SW flow for this purpose is provided from Aux. Bldg. SW Header 1A. The temperature control is performed by a local temperature controller. The pneumatic controller has a temperature sensing bulb located in the SFP coolant outlet of the heat exchanger. This temperature controller modulates the SFP Heat Exchanger Outlet Valve (SW- 1601 /CV-31086) to maintain a constant temperature. The control valve fails open on loss of air supply.

When the DG is started, the associated control valve goes to the fully open position. When the DG stops, the heat exchanger outlet valve closes. The valve fails open on loss of solenoid power or loss of DG startup air.

3.6.11 Blowdown Tank Spray SW Control Valve (See Figure KNP-SW02)

SW flow is used to maintain a controlled temperature in the Steam Generator Blowdown Tank or drain line. This control is implemented by modulation of the Blowdown Cooling Water (SW) Spray Control Valve SW-2303/CV-31053. This SW spray valve is an air operated, 1 inch valve. A local pneumatic controller is used to sense the temperature in the Blowdown Tank drain line. The output of the temperature controller (TC-26312), is used to modulate the cooling water spray Valve SS-2303. This valve fails open on loss of air supply.

3.6.12 Generator Hydrogen Cooler SW Valves SW is used to cool and control the temperature of the hydrogen which is used as the generator coolant. A closed loop analog control is provided for this purpose.

Controller CS-43001 is located on Mechanical Console "A". To implement the control loop, the hydrogen temperature is measured and compared to the selected setpoint (approximately 29' C) in the analog controller. The output pneumatic signal is used to adjust the position of Valve SW-2602/CV-31068. By adjusting Valve SW-2602, the hydrogen cooling rate is controlled. This valve fails open on loss of electrical power or loss of air supply.

The readings for March and April of 2008 were not readable due to fogging of the meter glass.

On June 4, 2008, the wells were repaired and both are being used for plant potable water.

Both well meters have failed after their last repair on June 4, 2008.

New totalizers installed on both pumps in March 2009. "A" totalizer installed on 3/2/09 and "B" installed 3/3/09.

Dominion Memorandum January 11, 2008 To: Richard Gallagher Company: Dominion Department: Nuclear Proj ects-Kewaunee License Renewal Location: Millstone Power Station From: Thomas Hooker Company: Dominion Department: Nuclear Projects Location: Kewaunee Power Station Groundwater Usage at KPS At your request, I have taken Deep Well Pump Readings on five occasions between October, 2006 and September 2007. The purpose of these readings has been to derive average groundwater usage, for use in the Kewaunee License Renewal Environmental Report. It is my understanding that these readings are being used as an independent backup to monthly totalizer readings to verify usage.

To perform these calculations, I derived pump rates using manufacturer flow curves, referenced against measured pump pressure. During each sampling event, I determined the amount of time the pump was actually on, based on Control Room instrumentation, average pump pressure based on local discharge pressure gauges, and calculated gallon per minute (gpm) usage, based on total elapsed time. During these five sampling periods, average flow ranged from 25.4 gpm to 60.8 gpm, as shown in the table below.

Date Total Flow (Gallons) Total Elapsed Time Average Usage (Minutes) (Gallons/Minute) 10/03/06 1669.2 65.58 25.4 11/06/06 2062.3 61 33.8 1/18/07 3154.8 66 47.8 2/08/07 3146 59.5 52.8 2/09/07 3133 60.75 52 9/19/07 3998 65.75 60.8 9/19/07 3998 65.75 60.8
