Additional Information Regarding Environmental Review Land Use L-1. Verify that current land use at the site and in the vicinity is the same as described in the 1978 FES-OL. Provide a map of the Watts Bar site and vicinity with detail on current land-use coverage categories. This map should reproduce clearly in black and white for use in hardcopy and website versions of the Nuclear Regulatory Commission (NRC) EIS.
A map of the WBN site and vicinity showing current land use is attached.
L-2. As discussed at the site audit, provide land acreage estimates of major coverage type categories (e.g., forested, built-up, etc.) within the site and boundary and within the vicinity of the site.
Attached is a spreadsheet that provides the land acreage estimates for the land use classes shown on the map (see L-1).
Transmission Lines TL-1. As discussed at the site audit, provide a map of the Watts Bar transmission system within the site and to the nearest substations. Include corresponding description of relevant dimensions (e.g., length and width of the corridors) and land-use coverage type in transmission corridor. This map should reproduce clearly in black and white for use in hardcopy and website versions of the NRC EIS.
Attached are plot figures that show the dimensions of the transmission corridors and the transmission line numbers associated with the plot. The numbers at the bottom are estimated brush acres to be mowed, or herbicide acres, and total easement acres, along with plot dimensions.
Socioeconomics S-6. Provide data on the capacity and average usage for regional (i.e., Rhea and Meigs Counties) water and sewer utilities (including DecatUr Water Department, Dayton Water Department and Wastewater Treatment, Spring City Water System and Waste Treatment, and Watts Bar Utility District).
The following data was obtained for regional water and sewer utilities:
Utility Capacity Average Daily Usage
-Dayton Wastewater Treatment Plant 2.67 million gallons/day 1.8 MGD (MGD)
Decatur Water Department -
wastewater 0.34 MGD Not provided Decatur Water Department 1 MGD Not provided Spring City Water 1.5 MGD 0.51 MGD Spring City Sewage 1.1 MGD 0.6 MGD Watts Bar Utility District 1.8 MGD 0.89 MGD E1-1
Benefit-Cost BC-2. Provide an estimate of levelized operating (i.e., delivered cost) costs associated with power generation from Watts Bar Unit 2 and describe relevant assumptions, including assumed capacity factor. Indicate the amount (either as a percent or in cents/kWh) attributable to fuel costs, decommissioning expenses, and waste disposal costs.
An estimate of the operating costs associated with the operation of WBN Unit 2 is attached.
Hydrology H-5. In order to better understand the impact of plant operations on site groundwater, provide information on the stage fluctuation of the yard holding pond during a recent year of operations. How are those fluctuations expected to change when WBN Unit 2 begins operation?
A plot of the actual water surface elevation (WSEL) measured for the yard holding pond (YHP) is given in Figure 1 for the year 2001. This year is close to normal in terms of the overall summer hydrology and meteorology in the Eastern Tennessee Valley. Also shown is the expected WSEL in the YHP for the same year based on a simulation of WBN with the operation of both Unit 1 and Unit 2. The computer code and output files for the simulation are provided in the response for RAI H-15.
The following general comments are provided in terms of the operation of WBN with two units versus one unit:
The average WSEL in the pond is expected to be higher with the operation of two units. This is because with two units, the blowdown discharge will be larger, requiring more storage in the YHP when the flow cannot be released from Outfall 101 (i.e., when the release from Watts Bar Dam is less than 3,500 cfs). Based on the results shown in Figure 1, the average WSEL in the YHP is expected to be about 1.75 feet higher with the operation of two units.
Due to the larger blowdown flowrate, the WSEL in the pond with two units will both rise and fall faster than with the operation of one unit.
The YHP is not expected to exceed the overflow elevation with normal operation of two units.
H-6. The ARCADIS report reviewed at the site audit showed the impact on the water table of a French drain surrounding the power block. How much water is pumped from the French drain annually?
Approximately 2.6 x10 8 gallons per year are pumped from the French drain.
H-9. Provide a current table of dilution factors and travel times for downstream water users within an 80-kilometer (50-mile) radius of the WBN Plant.
El -2
Have any of the users listed in the 1995 EIS ceased water withdrawal? Are there new users to be considered? Have any changes occurred that result in changes to the dilution factors reported.
The following users have ceased withdrawal:
U.S. Army Volunteer Ammunition Plant Rock-Tennessee Mill Dixie Sand and Gravel Chattanooga Missouri Portland Cement Signal Mountain Cement (TRM 433.3R)
Note: The water users down river of Tennessee-American Water are outside of the 50-mile radius.
There are no new users to be considered. However, the following user name changes have occurred:
E.I. DuPont Company is now Invista-Dupont Company Signal Mountain Cement (TRM 454.2R) is now BUZZI UNICEM USA Mead Corporation is now Smurfit Stone Reference information for the cited table indicates that the computations for the dilution factors were performed based on a rectangular channel of 1100 feet in width and 30 feet in depth, a river flow of 27,800 cfs, and a diffuser discharge of 62 cfs. The channel width of 1,100 feet is representative of the width of the Tennessee River in the upper portion of Chickamauga Reservoir, and the depth of 30 feet is roughly representative of the average depth of the main channel in reservoir for winter pool conditions, when river velocities are high. The flow of 27,800 cfs is the approximate average annual flow past WBN, and 62 cfs is the average annual flowrate from the plant diffusers for normal operation of the plant with two units. The latter is as anticipated by TVA in the original work to estimate the dilution factors. Between the time these computations were performed and now, the geometry of Tennessee River and the expected average annual flow past the plant have not changed.
The most recent TVA analyses for the plant water balance, summarized in response to RAI H-14, suggests a flowrate for the plant diffusers (Outfall 101) of about 64 cfs for operation with two units. This is not considered a material change from the conditions of original computations. As such, at this time, TVA feels that there is no need to update values for the dilution factors in the table.
With the above responses, a current update of dilution factors and travel times is given below:

For hydrothermal compliance, the WBN cooling system contains three outfalls to the Tennessee River. Outfall 101 is the diffuser, Outfall 102 is the emergency overflow from the YHP, and Outfall 113 is discharge structure for the SCcW system. The current NPDES status for hydrothermal compliance for each outfall is available to WBN operators in the control room via the display shown in Figure 1. In addition, the TVA River Forecast Center (RFC) in Knoxville has a continuous display on a large-panel screen that summarizes the current hydrothermal status of all TVA thermal plants that usually require NPDES attention,
-including WBN. An example of the RFC display is shown in Figure 2. With this introduction, a discussion of each WBN outfall relative to the requested information is provided herein.

~*76.0iF' Figure 2. TVA River Forecast Center Display for NPDES Hydrothermal Compliance Outfall 101 The operation of Outfall 101 depends on the release of water from Watts Bar Dam. Based on the NPDES requirements, if the release is less than 3,500 cfs, Outfall 101 is automatically removed from service by an interlock circuit. When flow from the dam is resumed at levels above 3,500 cfs, the interlock is released and an annunciator in the control room sounds to indicate "RIVER FLOW LO DISCHARGE TERMINATED." In response to the alarm, operators confirm the status of the flow control valves and the operation of the SCCW system (see page 27 of TVA WBN ARI-159-165, 2006). If desired, the diffuser flow control valves can be opened at this time. Depending on other operating requirements of the plant, the plant may choose to continue to keep the diffuser/Outfall 101 out of service. Since the operation of the diffuser is linked to the operation of Watts Bar Dam, it is possible for the diffusers to be cycled closed and open several times a day depending on the schedule for hydro peaking at the dam. That is, under normal winter and summer operating conditions, Outfall 101 can be closed and opened daily.
The NPDES temperature limit for Outfall 101 is a daily average value of 95°F. Plant instrumentation is provided to measure the Outfall 101 temperature continuously. If an instantaneous value of the measurement reaches 950F, an annunciator in the control room sounds to indicate "DIFFUSER TEMP HI." In response to the alarm, operators open the E1-8
flow control valve for the YHP (if it is closed), close the flow control valves-for the diffuser, confirm proper operation of the Condenser Cooling Water (CCW) System, and notify site environmental personnel to evaluate NPDES compliance (see page 44 of TVA WBN ARI-159-165, 2006). The immediate impact of this operation terminates releases to the river and routes the cooling tower blowdown to the YHP, thereby preventing exceedances of the NPDES temperature limit. For normal winter and summer operating conditions, the flow control valve for the YHP is open, so termination of flow to the river usually only involves closing the flow control valves for the diffuser. It is important to emphasize that this operation occurs based on an instantaneous measurement of 950F, whereas the NPDES limit is based on a daily average measurement. In this manner, WBN is notified of encroaching conditions well in advance of a genuine threat to the NPDES limit. Since the startup of the plant, events have occurred in the late afternoon of hot, humid days in warm summers where the instantaneous temperature for Outfall 101 has reached 95 0F and triggered the annunciator. When this occurs, site environmental personnel consult with pertinent staff to evaluate hydrothermal conditions, and if needed, implement changes in the operation of WBN and/or the river to protect the NPDES limit. With this strategy, since the startup of the plant, the daily average discharge temperature for Outfall 101 has never reached 950F.
Outfall 102 The overflow from the YHP is for emergency situations only. As such, under normal winter and summer operations there is no discharge from Outfall 102. Under normal winter and summer operations, filling of the YHP occurs when Outfall 101 is out of service (i.e., when the release from Watts Bar Dam is below 3,500 cfs). To ensure that no unexpected overflow occurs from the YHP, the WSEL in the YHP is monitored continuously. The WSEL measurement is available to operators in the WBN control room via the display shown in Figure 1. The overflow elevation of the YHP is 707 feet msl. Currently, a computer-generated alarm is issued in the control room if the WSEL in the YHP reaches 705.8 feet msl. For a blowdown rate of about 28,700 gpm, which is expected to be typical for the combined operation of Unit 1 and Unit 2 (see response to RAI H-14, Table 21), this provides a notification of about 51/2 hours before the pond WSEL will reach the overflow elevation, if flow into the pond is not terminated. There presently is no formal operating procedure specifying a required response to the YHP alarm. The current practice is for the control room to informally contact the TVA RFC in Knoxville and request an evaluation of the scheduled releases from Watts Bar Dam, and if needed, to implement changes in the releases so that Outfall 101 can be returned to service (i.e., allow the YHP to drain through the diffuser).
In addition to the computer-generated alarm in the WBN control room, there are two other systems that issue alarms for a high WSEL in the YHP. The first is a callout computer that monitors the WBN Environmental Data Station (EDS). The EDS callout computer continuously monitors the status of the WBN hydrothermal data and automatically issues telephone notifications if hydrothermal parameters reach or exceed established administrative limits. The callout computer also issues notifications if the hydrothermal data fails-to pass certain validation tests, or if the hydrothermal instrumentation does not respond to data requests (i.e., identifies potential instrumentation problems). Currently, the callout computer issues a notification to the TVA RFC in Knoxville when the YHP WSEL reaches 705.9 feet msl. The second system is the hydrothermal compliance display in the TVA RFC (i.e., Figure 2). When the YHP WSEL reaches 705.9 feet ms I, the background color for the current value of the YHP WSEL changes from green to yellow (caution). If the YHP WSEL E1-9
reaches 706.4 feet msl, the background color changes from yellow to red (action). When an EDS callout notification or a yellow or red alarm is obtained in the TVA RFC, pertinent staff in TVA River Operations is contacted informally to perform evaluations and develop options for preventing an overflow of the YHP. Thus far, the duplicity in monitoring and alarming of the YHP water level has been successful in ensuring that an unexpected overflow of the YHP does not occur (i.e., computer-generated alarm in the WBN control room, EDS callout notification, and hydrothermal compliance display in the TVA RFC).
Outfall 113 The operation of Outfall 113 is restricted by the NPDES water temperature limits summarized in Table 1. In addition, the NPDES permit also specifies that there shall be a release of at least 3,500 cfs from Watts Bar Dam whenever there is a change in operation of the SCCW system.
Table 1. NPDES Temperature Limits for SCCW Discharge/Outfall 113 Parameter Sample Period NPDES Limit Temperature at Downstream End of Running 1-Hr Avg 86.9°F Mixing Zone Temperature Rise from Ambient to Downstream End of Mixing Zone Temperature-Rate-of-Change at Downstream End of Mixing Zone Running 1-Hr Avg

In general, there are three modes of operation of the SCCW system-out of service, in service with bypass closed (summer mode), and in service with bypass open (winter mode). The different modes of operation are provided primarily for maintaining compliance with the NPDES temperature limits given in Table 1. Other objectives in operating the plant, however, can dictate the mode of operation of the SCCW system. Under normal winter and summer operating conditions, the SCCW system will be summer mode. In infrequent events where the meteorology and hydrothermal conditions of the river do not provide adequate dilution of the effluent from Outfall 113 (i.e., when the temperature limits summarized in Table 1 are threatened), the SCCW system will be moved from summer mode to winter mode, and in the most extreme events, removed entirely from service.
System Operating Instruction (SOI) 27.03 provides the formal requirements for operating the SCCW system (TVA SOI-27.03, 2007). In terms of NPDES requirements, however, SOI-27.03 includes steps only to ensure that any change in operation of the SCCW system is accompanied by a river flow of at least 3,500 cfs. Guidance on how to operate the SCCW system with respect to the NPDES requirements in Table 1 currently relies on informal procedures tied to real-time monitoring of the NPDES temperatures and in performing river temperature forecasts.
El-10
All the NPDES temperature parameters in Table 1 are available to operators in'the WBN control room via the display shown in Figure 1. The same is true for the TVA RFC in.
Knoxville via the display shown in Figure 2. The EDS callout computer also monitors these temperature parameters. Each of these monitoring systems have alarm levels-those in the WBN control room issued by a computer-generated alarm, those by the EDS callout computer issued by a telephone notification, and those in the TVA RFC by changes in the screen colors. For each monitoring system, Table 2 provides a summary of the current alarm levels for each of the NPDES parameters listed in Table 1. As before, there presently are no formal operating procedures specifying a required response to these alarms. In response to an alarm, the current practice is for the WBN control room to informally contact the TVA RFC in Knoxville and request an evaluation of the SCCW system to determine if changes in operation should be implemented. Independently, when an alarm is obtained in the TVA RFC in Knoxville, pertinent staff in TVA River Operations is contacted to perform evaluations and develop options for preventing an NPDES exceedance for the SCCW system.

Using a hydrothermal model for the WBN cooling system, the forecast is performed by staff in the TVA RFC. Based on the expected conditions of the river (ambient water temperature and flow), the forecast meteorology, and the expected operation of WBN, the hydrothermal model provides a prediction of the hourly river temperature at the downstream end of the Outfall 113 mixing zone. The prediction is used to provide a recommendation to WBN for the operation of the SCCW system. The forecast is issued by email almost every day. An example email is shown in Figure 3.
Again, the duplicity in monitoring and alarming of the real-time temperature measurements, along with the routine hydrothermal forecast, thus far has been successful in ensuring that' the impact of the SCCW system does not exceed NPDES water temperature limits.

Outlook - Tuesday 1126110 and beyond The current forecastsuggests that it will be safe to operate.the SCOW system in sumimer mode through Sunday, January 31, 2010.
Forecast Notes The next forecast will be issued Monday, 1/25/10, unless actual conditions stray apprediably from predicted conditions, in which case the next forecast will be issued sooner.
Figure 3. Example Hydrothermal Forecast for Operation of WBN SCOW System H-14. Provide a water balance and heat balance for the operation of WBN Units 1 and 2.
Indicate where incremental increases in water use will occur as a result of initiating operation of Unit 2. Provide this information for normal summer and winter operation and for the operational mode which has the greatest impact on the receiving water body (effluent temperature, instream temperature, and instream temperature rate of change).
Since completing the FSEIS in 2007, TVA has a fuller understanding of the expected operation of the SCOW system. The hydrothermal model used to estimate the thermal impact of the plant on the receiving waterbody (i.e., Tennessee River) has been updated to reflect this understanding. However, to provide an expeditious response to this RAI, analyses with the updated model had to be limited to steady-state evaluations. That is, in the FSEIS of 2007, an unsteady model was run with an hourly time step to simulate the hourly operation of the plant over a period of 30 years. The average and extreme (e.g.,
maximum and minimum) impacts in the river were then determined based on statistical properties of the hourly model results. In the analyses summarized herein, the time histories of the hydrologic and meteorological data were first analyzed to determine average and extreme hourly values for each month of the year. These were then used as input in the steady-state model to estimate the thermal impacts for the cases specified in this RAI.
In addition to updating the model for the operation of the SCOW system, other updates were made to capture better the range of operation of the Intake Pumping Station (IPS). The following discussions provide summaries of the model changes, the hydrologic and meteorological data used in the model simulations, and the model results. To respond to the requested information for normal summer and winter operation, simulations were performed based on the statistical characteristics of the expected hydrology and meteorology for each month of the year. To respond to the requested information for the greatest impact on the receiving waterbody, model simulations were performed for five specific cases with extreme hydrology and meteorology.

In this section TVA states (page 26), "If WBN Unit 2 is completed, the current plan is to supply the SCCW to both the Unit 1 and the Unit 2 CCW systems." This is again emphasized in Section 3.1.1 where TVA states (page 37), "With the combined operation of Unit 1 and Unit 2, the SCCW system would serve both units." At the time of the 2007 FSEIS, it was anticipated that-any modifications to the SCCW system associated with the addition of Unit 2 would not require changes in the design capacity of the plant outfalls to the Tennessee River. These include the diffuser (Outfall 101), the emergency overflow for the YHP (Outfall 102), and the SCCW discharge structure (Outfall 113). This was emphasized in Section 3.1.1 where TVA states (page 34), "For the combined operation of Unit 1 and Unit 2, the control structures that regulate the amount of flow between and out of the cooling tower basins would need to be modified to preserve the original design bases for all three outfalls." Based on this assumption, the hydrothermal analyses summarized in Section 3.1.1 of the FSEIS specified the inflow and outflow of the SCCW system for the combined operation of Unit 1 and Unit 2 to be the same as that for the current operation of Unit 1. As a gravity-driven system, this was accomplished by assuming the water levels in the cooling tower basins remained unchanged for both cases. It also was assumed that the SCCW system would serve only Unit 2 (page 37).
The operation of the SCCW system for the combined operation of Unit 1 and Unit 2 is expected to resemble that shown schematically in Figure 1. With this, the hydrothermal model was updated to provide a better estimate of the flows entering and exiting the cooling tower basins. This was accomplished by incorporating in the model the hydraulic characteristics of the key inflow and outflow structures for the basins, and computing the expected water levels in the basins. In contrast to the hydrothermal analyses of the 2007 FSEIS, this allows an estimate of the potential magnitude of changes in the inflow and outflow of the SCCW system due to the combined operation of Unit 1 and Unit 2 versus the current operation of Unit 1. The same is true for the blowdown.
Furthermore, to better estimate impacts for the combined operation of Unit 1 and Unit 2, and again in contrast to the 2007 FSEIS, model simulations for this RAI were performed for the SCCW system serving both units rather than solely Unit 2.
IPS Table 1 provides a summary of assumed operating conditions of the IPS for this RAI. The IPS includes pumps for the ERCW system, the RCW system, the Screen Wash System, and the Fire Protection System. The screen wash pumps and fire protection pumps are operated only intermittently, and thus are not significant in representing normal operation of the plant. A configuration representing the typical annual average water use of the IPS (+/-
10 percent) is given by the operation of two ERCW pumps and four RCW pumps. For this configuration, the combined flow delivered to the plant by the ERCW and RCW systems is about 39,500 gpm. With the operation of both Unit 1 and Unit 2, the operation of the plant is expected to vary between a normal configuration represented by two ERCW pumps and six RCW pumps and a normal max configuration represented by four ERCW pumps and six RCW pumps. For the former, the combined flow delivered to the plant by the ERCW and RCW systems is about 52,100 gpm. For the latter, the combined flow delivered to the plant by the ERCW and RCW systems is about 78,200 gpm. This is similar to a flow as high as an accident condition. This RAI is concerned with the water and heat balance for the operation of both Unit 1 and Unit 2. For this case, in order to bound the potential order of El-13
magnitude of the plant thermal impacts, the plant is assumed to operate in the normal maximum mode as defined in Table 1. This represents an update from the hydrothermal analyses summarized in the 2007 FSEIS, which were performed assuming the operation of the IPS with four ERCW pumps and four RCW pumps, delivering a combined flow to the plant of about 68,700 gpm.
Basic Hydrologic and Meteorolo-gical Data River Flow The river flow used in the analyses included the hourly release from Watts Bar Dam for years 1976 through 2009. For years 1976 through 2004, the hourly release is based on a simulation of the upstream portion of the TVA river system using historical runoff for 1976 through 2004, and assuming operation of the river system consistent with the policy established by the TVA Reservoir Operations Study (ROS) of 2004 (http://www.tva.gov/environment/reports/ros eis/index.htm). For years 2005 through 2009, actual hourly releases from Watts Bar Dam were used in the analyses, since the river system was operated in accordance with the ROS operating policy in these years. The basic monthly statistics for the hourly river flow are summarized in Table 2.
Ambient River Temperature The ambient river temperature used in the analyses included the hourly release temperature from Watts Bar Dam for years 1976 through 2009. For years 1976 through 2004, the hourly release temperature is based on a simulation of the upstream portion of the TVA river system using historical runoff and meteorology for 1976 through 2004, and assuming operation of the river system consistent with the policy established by the ROS. For years 2005 through 2009, actual hourly release temperatures from Watts Bar Dam were used in the analyses, since the river system was operated in accordance with the ROS operating policy in these years. Note that the NPDES permit for the plant specifies that the hourly release temperature from Watts Bar Dam as the ambient temperature for monitoring compliance to permit limits for river temperature. The basic monthly statistics for the hourly ambient river temperature are summarized in Table 3.
Wetbulb and Drybulb Air Temperature The drybulb and wetbulb air temperatures used in the analyses were obtained from measurements at the Chattanooga airport for years 1976 through 2009. The basic monthly statistics for the hourly drybulb and wetbulb temperatures are summarized in Table 4 and Table 5, respectively.
Difference between Wetbulb Temperature and Ambient River Temperature The difference between the wetbulb temperature and ambient river temperature provides a measure of the expected difference between the plant effluent temperature and the ambient river temperature. This is because the effluent discharge temperature from the hyperbolic draft cooling towers tends to track in parallel with the wetbulb temperature. Data for the difference between the wetbulb temperature and ambient river temperature is used to estimate the hydrologic conditions that are likely to produce the largest plant-induced water E1-14
temperature impacts. Using the data sources summarized above, the basic monthly statistics for the difference between the hourly wetbulb and hourly ambient river temperature are summarized in Table 6.
Water Surface Elevations in Watts Bar Reservoir and Chickamauga Reservoir Since the WBN SCCW system is a gravity-fed system, the amount of flow entering the SCCW system depends on the WSEL in Watts Bar Reservoir. Furthermore, the depth of water in the river below Watts Bar Dam influences the dilution of the plant effluent for the diffuser discharge (Outfall 101) and for the SCCW discharge (Outfall 113). This depth is controlled by the WSEL in Chickamauga Reservoir. For the simulations summarized herein, the assumed WSELs for Watts Bar Reservoir and the upper end of Chickamauga Reservoir are summarized in Table 7. These elevations correspond to the approximate seasonally normal levels for these reservoirs based on the current operating policy for the TVA river system.
Model Simulations Operation of Unit I and Unit 2 for Normal Winter and Summer Conditions To capture the potential variation in thermal impact between winter and summer conditions, model simulations of the plant were performed for each month of the year. The basic operating assumptions for each month are summarized in Table 8. Monthly average hourly values were used for the river flow, river temperature, drybulb temperature, and wetbulb temperature (i.e., from Table 2, Table 3, Table 4, and Table 5). Each unit was assumed to be operating at full power with four CCW pumps. The cooling towers were assumed to have a capability of 105 percent, and the IPS was assumed to be providing flow with four ERCW pumps and six RCW pumps. Water levels in Watts Bar Reservoir and Chickamauga Reservoir were based on the information provided in Table 7. On an average annual basis there is no net storage in the YHP, thus no outflow was assumed to occur from the pond. In the model simulations this is accomplished by assuming a pond WSEL of 698 feet msl, which is the elevation of the pond outlet structure. For conditions based on monthly average hourly river flows, releases from Watts Bar Dam are high enough to allow the operation of the SCCW system in summer mode for each case. With these assumptions, simulation results for the heat balance are given in Table 9. Results for the water balance and thermal impacts for each of the plant outfalls are given in Table 10. It is emphasized that with the YHP WSEL at 698 feet msl, there is no overflow for pond (i.e., Outfall 102). Overflow from the YHP currently is not expected for any normal operating conditions of the plant. It again is emphasized that this version of the hydrothermal model provides estimates only for a steady-state snapshot of the prevailing operating conditions. Temperature rate-of-change events due to variations in meteorology and river flow would be of the same order of magnitude as that determined by the 30-year dynamic simulations presented in Section 3.1.1 of the 2007 FSEIS.
Operation of Unit I and Unit 2 Yielding the Greatest Impact on the Receiving Waterbody The operational modes yielding the greatest impact on the receiving waterbody have been captured in five cases. These are summarized in Table 11. The basic operating assumptions for these cases are summarized in Table 12. Each unit was assumed to be operating at full power with four CCW pumps. The cooling towers were assumed to have a capability of 105 percent, and the IPS was assumed to be providing flow with four ERCW El-15
pumps and six RCW pumps. With the above assumptions, simulation results for the heat balance are given in Table 13. Results for the water balance and thermal impacts for each of the plant outfalls are given in Table 14. Other comments regarding each case include the following:
Case 1: The case producing a maximum instream temperature rise for Outfall 101 would occur during low river flow in the late winter/early spring months of the year, when the river temperature is cool but meteorology can produce days with high drybulb and wetbulb temperatures. The minimum river flow for which releases can be provided from Outfall 101 is 3,500 cfs, which is assumed for this case. Per the plant NPDES permit, releases cannot be made from Outfall 101 below this value. A control system between Watts Bar Dam and WBN is provided to close automatically the WBN diffuser when the release from the Watts Bar hydroplant drops below 3,500 cfs. In reality, for this case, a flow of 3,500 cfs is considered conservative because the minimum flow for a single hydroturbine at Watts Bar Dam is about 4,500 cfs. To produce the maximum discharge from Outfall 101, the YHP was assumed to be at the maximum level (no overflow) and draining to Outfall 101. The WSEL in the YHP corresponding to this condition is 707 feet msl. For the assumed conditions of the river and meteorology, the plant could operate with the SCCW system in summer mode.
Case 2: The case producing a maximum instream temperature rise for Outfall 113 also would occur during low river flow in the late winter/early spring months of the year, when the river temperature is cool but meteorology can produce days with high drybulb and wetbulb temperatures. The SCCW can operate with a river flow of 0 cfs, which was assumed for this case. For this flow, and for the reason cited above, there would be no discharge from Outfall 101 to the river-all the flow exiting the Unit 1 cooling tower basin by the blowdown weir would be diverted to the YHP. As such, for this case, the WSEL in the YHP is irrelevant. To be consistent with all the cases of Table 11, a YHP WSEL of 707 feet msl was assumed. For these conditions, the plant could operate with the SCCW system in winter mode. However, the results of the Case 2 simulation indicate that with this mode of operation, the temperature rise for Outfall 113 would be equivalent to the maximum allowable NPDES temperature rise for this outfall, 5.40F. For this reason it needs to be emphasized that whereas the plant could operate at this condition from a theoretical standpoint, because of the uncertainty of hourly variations in river flow and meteorology, such would never occur in practice. Procedures for monitoring thermal compliance would dictate changes in the operation of the river and/or WBN if the temperature rise were to reach about 4.90F. If the SCCW system were already operating in winter mode, and if there was not enough water in the river system to increase the release from Watts Bar Dam, the SCCW system would be removed from service. These procedures are discussed in more detail in the TVA response for RAI number H-13.
Case 3: The case producing a maximum combined instream temperature rise at Outfall 101 and Outfall 113 is the same as Case 1.
Case 4: The case producing a maximum instream temperature for Outfall 101 would occur during low river flow in the summer, when the river temperature is warm and the meteorology produces days with high drybulb and wetbulb temperatures. For this case the minimum river flow for the operation of Outfall 101 was again assumed, 3,500 cfs.
As for Case 1, a flow of 3,500 cfs is considered conservative because the minimum flow for a single hydroturbine at Watts Bar Dam is about 4,500 cfs. An extreme combination E1-16
of the drybulb and wetbulb temperatures was assumed, based on the historical meteorology. Similarly, an extreme value of the ambient river temperature also was assumed. To produce the maximum discharge from Outfall 101, the YHP again was assumed to be at the maximum WSEL, 707 feet msl (no overflow), and draining to Outfall 101. For the assumed conditions of the river and meteorology, the plant could operate with the SCCW system in summer mode.
Case 5: The case producing a maximum instream temperature for Outfall 113 is the same as Case 4, except for a river flow of 0 cfs rather than 3,500 cfs. There would be no discharge from Outfall 101 to the river-all the flow exiting the Unit 1 cooling tower basin by the blowdown weir would be diverted to the YHP. As before, the WSEL in the YHP is irrelevant, and a value of 707 feet msl was assumed for consistency. For these conditions, the plant could operate with the SCCW system in summer mode. However, the results of the Case 5 simulation indicate that with this mode of operation, the instream temperature for Outfall 113 would be equivalent to the maximum allowable NPDES temperature for this outfall, 86.90F. As for the temperature rise for Case 2, whereas the plant could operate at this condition from a theoretical standpoint, because of the uncertainty of hourly variations in river flow and meteorology, such would never occur in practice. Procedures for monitoring thermal compliance would dictate changes in the operation of the river and/or WBN if the temperature were to reach about 86.4°F.
If it were not possible to provide cooler releases from Watts Bar Dam, the operation of the SCCW system would be shifted from summer mode to winter mode.
To provide a basis for comparison of the above results, model simulations also were performed for the current operation of Unit 1. This includes both the normal winter and summer conditions and the cases yielding the greatest impact on the receiving waterbody.
For the IPS, the model simulations were performed for the case in Table 1 considered representative of Unit 1 operating experience.
Operation of Unit 1 for Normal Winter and Summer Conditions The basic operating assumptions for each month are summarized in Table 15. Simulation results for the heat balance are given in Table 16, and results for the water balance and thermal impacts for each of the plant outfalls are given in Table 17.
Operation of Unit 1 Yielding the Greatest Impact on the Receiving Waterbody The operational modes yielding the greatest impact on the receiving waterbody are the same cases summarized in Table 11. The basic operating assumptions for each case are summarized in Table 18. Simulation results for the heat balance are given in Table 19, and results for the water balance and thermal impacts for each of the plant outfalls are given in Table 20.
Comparison of Flow for Unit 1 Operation Versus Combined Operation Of Unit 1 and Unit 2 Based on averages of the results for each month as present in Table 10 and Table 17, a comparison of the estimated average plant inflows and outflows for the sole operation of Unit 1 versus the operation of both Unit 1 and Unit 2 is given in Table 21. These flows are only for the plant waste heat dissipation, although this encompasses the vast majority of the plant water use. The following items are emphasized:
E1-17
(i) Plant Inflow Because of the greater number of pumps in service, the inflow from the IPS is higher for the operation of Unit 1 and Unit 2. Recall that simulations for the operation of Unit 1 assumed two ERCW pumps and four RCW pumps in service, whereas simulations for the operation of Unit 1 and Unit 2 assumed four ERCW pumps and six RCW pumps in service.
The SCCW inflow estimated for the operation of Unit 1 and Unit 2 is about 9 cfs (3 percent) lower than that for the operation of Unit 1. This is because for the operation of Unit 1 and Unit 2, the water level in the Unit 2 cooling tower basin is higher, which reduces slightly the head for delivering SCCW flow from Watts Bar Reservoir.
(ii) Plant Outflow Cooling tower evaporation for the operation of Unit 1 and Unit 2 is about twice that for the operation of Unit 1, obviously because the former case includes two rather than one tower in service.
The outflow through the diffuser/Outfall 101 for the operation of Unit 1 and Unit 2 is about 11 cfs (21 percent) higher than that for the operation of Unit 1.
The outflow through the SCCW discharge/Outfall 113 for the operation of Unit 1 and Unit 2 is about 35 cfs (13 percent) higher than that for the operation of Unit 1.
(iii)
Distribution of Plant Discharge Among the Outflow Points The fraction of the total plant discharge evaporated into the atmosphere by the cooling towers increases from about 8 percent for the operation of Unit 1 to about 14 percent for the operation of Unit 1 and Unit 2.
For the operation of Unit 1 and Unit 2, the fraction of the total plant discharge released to the river via the diffuser/Outfall 101 remains roughly the same as that for the operation of Unit 1, about 15 percent.
The fraction of the total plant discharge released to the river via the SCCW/Outfall 113 decreases from about 76 percent for the operation of Unit 1 to about 71 percent for the operation of Unit 1 and Unit 2.
H-15. Thermal Description and Physical Impacts. Provide the calculation package for all runs that support the application (CORMIX or other models). Include electronic copies of all input and output files.
The response presented herein focuses exclusively on the calculation package supporting the results summarized in Section 3.1.1 of the FSEIS (TVA, 2007). The calculations were made using a hydrothermal model developed by TVA that simulates the unsteady, combined operation of the plant and Tennessee River over an extended period of time. In this case, the simulations were performed over a period of 30 years, corresponding to recorded hydrology and meteorology from 1976 through 2005. Other basic aspects of the simulations are presented in the FSEIS. It is emphasized that the plant is assumed to operate in a normal mode throughout the simulations. For this operation, thermal impacts El-18
occur in the Tennessee River for the discharge from the diffusers (Outfall 101) and for the discharge from the SCCW system (Outfall 113). Mixing of thermal effluent from Outfall 101 is estimated based on the behavior of the thermal effluent observed in a physical model study of the discharge diffusers (TVA 1977a; TVA 1997b). Mixing of thermal effluent from Outfall 113 is estimated using CORMIX. In terms of the CORMIX simulations, the following additional comments are provided:
CORMIX Version 3.1 was used in modeling the mixing from the SCCW/Outfall 113. The original runs were made in 1997 and updated in 2004. This version of CORMIX accepted input only via keyboard entry. The desire, however, was to examine the thermal impact of the SCCW based on multiyear simulations with hourly variations in river conditions and meteorology. Hourly computations, however, could not be performed in a reasonable manner with a keyboard-entry model. To overcome this issue, CORMIX simulations were performed for a limited number of cases encompassing the expected range of conditions for the river and plant. The results of these simulations then were used in an interpolation scheme wherein the hourly instream river temperature rise due to the discharge from the SCCW system was computed based on the prevailing hourly conditions of the river and plant. The interpolation scheme was based on five key parameters: river depth, river flow, ambient river temperature, SCCW discharge, and SCCW discharge temperature rise above ambient river temperature.
A rectangular shoreline surface discharge into a rectangular river channel was assumed for the SCCW outfall for all cases. In order to preserve the initial momentum of the flow from the outfall, the height and width of the modeled outfall were varied such that the depth of the discharge was equal to the difference between the river elevation and the elevation of the outfall invert (665 feet msl), with the width adjusted so that the cross sectional area of the outfall was equal to that of the 15-foot wide by 10-foot deep rectangular outfall. The modeled outfall depth thus varied from 10 feet to 18 feet, with corresponding widths of 15 feet and 8.3 feet, respectively.
" Values of the five key parameters for the interpolation scheme are as follows:
River Depth (Elevation)
- 1. El: River depth 3.3528 m (11 feet, corresponding to WSEL 675 feet msl)
River width 365.76 m (1200 feet)

H-18. What is the current expectation for blowdown discharge for operating WBN Units I and 2? The 2007 TVA EIS states "For the original heat dissipation system, the maximum discharge from the plant diffusers due solely from blowdown from the cooling towers was expected to be about 50 cfs for the operation of one unit and 85 cfs for the operation of both units (TVA 1977b)."
The results of model simulations presented in Table 10 of the response for H-14 provide the current expectations for blowdown for the combined operation of Unit 1 and Unit 2. In these simulations, the blowdown from the cooling towers is given by the discharge from El-20
Outfall 101. Depending on seasonal conditions, the results suggest that the blowdown will vary between about 54 cfs and 70 cfs.
H-21. The ER states (p. 52) "Operation of Unit 2 along with Unit 1 would result in an increase of raw water intake usage at the IPS by an estimated 33 percent compared to sole operation of Unit 1." Why does water withdrawn at the IPS only increase 33 percent for a doubling of the amount of cooling needed?
TVA's original estimate of a 33-percent increase was based on the best understanding of heat loads and system flows in 2007 with the expectation of the need for 4 ERCW pumps and 2 RCW pumps for two-unit operation. Based on modeling and actual calculations, TVA now estimates that dual unit operation will require 2 ERCW pumps and 6 RCW pumps, representing a 44 percent increase in raw water intake usage. Attached is a more detailed analysis of the cooling water requirements.
H-25, What is the concentration of total dissolved solids in the water discharged from the cooling tower basins through the diffuser? How does this compare to the concentration in the intake water Attached is an Excel data sheet with the total suspended solids (TSS).values for the water discharged from WBN via the diffuser or Outfall 101 (H-25 Discharge TSS), The data provides the date collected, date analyzed, time collected, time analyzed, the TSS value and if the TSS value is an excursion. TSS at the outfall is monitored per WBN's NPDES permit.
Attached is an Excel data sheet with the raw water turbidity (H-25 Raw water Turbidity) at the IPS. TVA does not sample for TSS in the intake water and has no way of comparing the intake water data with the diffuser discharge TSS.
H-26, On one of the tours during the site audit, we visited the onsite landfill and were told it is not currently being used. How will solid waste from operation of WNB Unit 2 be disposed of?
Solid waste (excluding radioactive and mixed waste) from the TVA WBN Unit 2 operations will be disposed of at the Rhea County Municipal landfill. Disposal of solid waste at the Rhea County Municipal landfill at the time of this response is more economically favorable to TVA; however, regardless of economics, TVA reserves the right to utilize the onsite landfill.
The landfill is operated in accordance with Watts Bar Nuclear Plant, Unit 0, Environmental Compliance Manual, Chapter 11, Non-Radioactive Solid Waste and Demolition Waste Landfill, Revision 0006. TVA maintains an active permit from Tennessee Department of Environment and Conservation (TDEC) Division of Solid Waste Management for the onsite landfill, Demolition Waste Landfill Registration No. DML 72-103-0025.

Chlorine, Organic Matter, Paint Compounds, Potable Water (Cooling Tower at Training Center), High Pressure Fire Protection flushes. Post-Oct 2008, this outfall no longer received OSN 111 effluent. Potable water and Superior SWS 4550 were re-routed to 112 Runoff Holding Pond OSN 101. Internal study of time for de-toxification of quaternary amine residue found in High Pressure Flushes yielded immediate de-toxification when the water made contact with soil prior to reaching the receiving stream feeding into the pond. In April 2009, WBN petitioned TDEC for TMSP coverage only.
Severe Accidents SA-1. As discussed at the site audit, provide MACCS input and output files for Watts Bar Unit 2 that include analyses for all severe accident release classes including the release class or classes in which radionuclides are released to reactor containment and containment remains intact.
Attached is the report for the Loss of Coolant Accident with containment intact. The MACCS files are also attached. The report concluded that overall the risk results are small.
SA-2. As discussed at the site audit, provide a discussion of the potential risks associated with external initiating events and accidents that might occur when the reactor is not at power and the relative frequency of such events and accidents.
E1-24
WBN has not performed a low-power shutdown Probabilistic Risk Assessment (PRA).
Currently for Unit 1, risk during low power and shutdown conditions is controlled by an outage risk management program based upon the qualitative defense in depth guidance given in NUMARC 91-06. WBN uses EPRI's ORAM-Sentinel program to track the safety function requirements prescribed in NUMARC 91-06.
Risk during shutdown from external events is bounded by the at power Individual Plant Examination of External Events (IPEEE) model. WBN performed an IPEEE for Unit 1 operation to identify any vulnerabilities to severe accidents from these events. The IPEEE for Unit 2 is currently in progress.
To address seismic events, WBN performed a Seismic Margins Assessment in accordance with EPRI NP-6041-SL for Unit 1. This analysis did not identify any adverse spatial interactions or components with a seismic capacity below the reference level of the Review Level Earthquake which is 0.3g. Only 4 components types had High Confidence Low Probability of Failure values below 0.4g. WBN expects that when reviewed Unit 2 components will also meet this standard.
TVA performed an analysis of internal fires using the Fire Induced Vulnerability Evaluation methodology for Unit 1. The evaluation results determined that core damage frequency (CDF) for fire areas would be below 1 E-06. WBN expects that when reviewed the CDF for Unit 2 fire areas will also be below 1 E-06.
WBN performed the screening review described in Supplement 4 to Generic Letter 88-20 and NUREG-1407 for Unit 1. A review was performed to determine if any changes around and at WBN had taken place since the issuance of the Unit 1 operating license in November 1995. The evaluation at the time revealed that the plant met the Standard Review Plan criteria and only one recommendation for plant improvement resulted. This recommendation was to modify an Auxiliary Building concrete canopy to provide additional protection against tornado missiles. This modification has been completed. This modification was to the Unit 2 side of the plant and is effective for both units.
The status of high winds, transportation and nearby facilities accidents remains similar to when the original review was performed. Since the time of the original IPEEE evaluation for external flooding an issue has been identified that resulted in an increase in the calculated Probable Maximum Flood (PMF) level for WBN. There has been a project underway to widen the locks at the Chickamauga Dam downstream of WBN. The temporary configuration during this construction period has resulted in some of the spillways credited in the flooding analysis being unavailable. The reduction in the number of spillways has caused the PMF level to be increased to 738.8 ft. This has been documented in the WBN corrective action program in Problem Evaluation Reports 211722 and 154477. The corrective action is implemented in AOI-7.01, "Maximum Probable Flood," which invokes the performance of MI-17-004, "Movement of Equipment Flood Mode Preparation." This MI installs temporary flood barriers around the Unit 1 thermal barrier booster pumps in accordance with temporary alteration TACF 1-09-0006-070. The issue will be examined in the Unit 2 IPEEE with a similar expected outcome.
E1-25
Severe Accident Mitiaation Alternatives (SAMA)
SAMA-1. As discussed at the site audit, provide a discussion of the extent to which the January 2009 assessment considers the risks (core damage frequencies) associated externally initiated events and events that might occur when the reactor is shut down.
As stated in the submittal the SAMA PRA model used is an internal events including internal flooding, at power model. A multiplication factor of 2 was applied to the internal events results to account for the contribution to core damage from other events. The factor of 2 was based on a review of the SAMA submittals for a number of plants and previous practice at WBN when preparing submittals involving risk applications such as Technical Specification (TS) Completion time changes. The NRC accepted this methodology for these submittals.
SAMA-2. As discussed at the site audit, provide a discussion of the bases for estimating the costs of implementing design alternatives for the January 2009 document.
The costs of design alternatives were determined by estimating various parameters including but not limited to the cost of the equipment and materials, potential cost of shipping, costs of engineering, labor costs, cost of operation personnel support, cost of procedure changes, cost of training, cost of Radcon personnel support, cost of security support, taxes and contingencies. Costs were estimated by upgrading previous Unit 1 estimates, completing new cost estimates by the WBN Engineering/Construction organization, or by using cost estimates from similar studies at other plants.
SECPOP2000 V3.12 was used for the MACCS2 Site Data File for Watts Bar. To account for inflation, economic values were escalated (1990 to 2007) using the following method.
The year 1990 was assumed to be the benchmark of all dollar input values, the CHRONC input file was compared with sample data that references NUREG/CR-4691, and the values were identical.
All of these input values are in units of dollars per human or land unit. The original data was assumed to be based on 1990 values. To adequately project the dollar values to the year 2007, an inflation factor of 1.555 was used to multiply each of these values.
U.S. Department of Labor annual consumer price index (CPI) values per year from 1990 to 2007 for the Midwest region was used to calculate the inflation factor. The 2008 annual value was not available due to this analysis being performed before the end of the calendar year 2008. A CPI is a measure of the average price of consumer goods and services purchased by households. The percent change in the CPI is commonly used for inflation.
The CPI can be used to index (i.e., adjust for the effects of inflation) wages, salaries, pensions, or regulated or contracted prices.
To find the correct multiplier to represent the cost increase from 1990 in 2007:
Annual CPI 2007 / Annual CPI 1990 = 198.12 / 127.4 = 1.555. The multiplier 1.555 was then applied to all costs that needed to be updated from 1990 to 2007. For example, the value of the input variable CHEVACST001 was updated as follows, CHEVACST001 in 1990
27.00 dollars/person-day, 27.00xl.5551 = 41.9877, therefore, CHEVACST001 in 2007
42.00 dollars/person-day. All other identified costs were updated in this manner.
E1-26
Terrestrial Ecology TE-1. As discussed at the site audit, provide a map of terrestrial habitats on the WBN site, including wetlands and streams.
A map showing wetlands and streams is attached.
TE-2. As discussed at the site audit, provide an updated list of federal-and state-listed species that may occur on or within 1/2 mile of the WBN site and transmission corridors.
Attached is an Excel file that lists protected species within 3 miles of each of the 500-kV lines that originate at WBN.
TE-3. Provide updated distribution and abundance information describing known occurrences of federal-and state-listed species within 1/2 mile of the transmission corridors that service the WBN site from the site to the first substation.
Attached is an Excel file that lists protected species within 3 miles of each of the 500-kV lines that originate at WBN.
TE-4. As discussed at the site audit, provide a list of and distribution information on exotic invasive species that may occur on the WBN site, within the transmission corridors, and within 1/2 mile of the WBN site and the transmission corridors.
Field reviews have noted the presence of the following non-native invasive species: Autumn olive, Chinese privet, Japanese stilt grass, Japanese honeysuckle, and multiflora rose.
These species along with other commonly occurring invasive plants such as kudzu, mimosa, princess tree, and tree of heaven could be present around the WBN reservation.
Radiological Protection RP-2. As discussed at the site audit, dose to biota was calculated in the 1978 NUREG-0478.
However, this analysis cannot be validated using the current guidance. The following information is needed to meet the intent of NUREG-1555, ESRP 5.4.4 (1) Identify the representative biota for the area (see ESRP 5.4.4).
(2) Identify the pathways of exposure to the biota (3) Based on the above, perform dose calculations to biota using the radioactive source term used for the human dose calculations As discussed during a phone call between NRC and TVA on January 7, 2010, NRC staff will use information previously submitted by TVA to complete this analysis.
E1-27
Transportation TR-2. In Section 3.16 of the TVA 2007 EIS, the applicant refers frequently to "tons" of new fuel.
Confirm that the unit is "MTU".
This is tons of new fuel assemblies including the slightly enriched uranium fuel and the nozzles, guide thimbles and grids that support the fuel. There is about 1,014 Ibm (460 Kg) of uranium in a single fuel assembly. Each fuel assembly weighs about 1,500 Ibm (or 680 kg).

SUBJECT:
THE SIZING OF THE SUPPLEMENTAL CONDENSER COOLING WATER (SCCW) SYSTEM SUPPLY, DISCHARGE AND BYPASS LINES DOCUMENT ID:
MDN1027-980006 1.0 PURPOSE The purpose of this calculation is to determine the following:
1.1 The size of the Supplemental Condenser Cooling Water System (SCCW) supply, discharge, and bypass lines that will accommodate the flow capacity requirements as described in the "Watts Bar Nuclear Plant Supplemental Condenser Cooling Water Project," Ref. 1.
1.2 The location of the bypass line.
1.3 The location of the motor-operated butterfly valves in the SCCW supply, discharge, and bypass lines.
1.4 The valve throttle positions that would meet the seasonal flow requirements as described in Ref. I.
1.5 The number of Intake Screen House bays needed to supply the flow capacity requirements in Ref. I.
2.0
!CRITERIA 2.1 The SCCW supply piping will supply between 115,000 and 135,000 gallons per minute (gpm) from the Watts Bar Lake to the Watts Bar Nuclear Plant (See Ref.
5.1). 115,000 gpm corresponds to the Nominal Winter level of 738', and 135,000 gpm corresponds to the Summer level of 740.5'.
2.2 The bypass line has to divert approximately 40% of the supply flow during the winter months to meet the "Thermal Plume Modeling" requirements (Ref. 5.2).
2.3 The supply, discharge and bypass valves must be placed in close proximity to each other and the Cooling Towers to facilitate electrical connections. The valves are placed at least 8 pipe diameters away from other piping components on either side of the valves.
2.4 The valves should have open angles between 300 and 90' (Standard 3.1).

.4.0 ASSUMPTIONS 4.1 PIPING 4.1.1 EZFLOW Version 5 is used because of its capability to model rectangular duct.
4.1.2 All piping is clean, smooth, concrete piping with a minimum Hazen-Williams factor (HW) of 130. EZFLOW uses HW= 100 as a default value for concrete. However, the Hazen-Williams factor for new concrete pipe could range from approximately 140 to 150 for the pipe sizes used in this calculation (Section 13 of Ref. 5.2). HW=130 and HW=150 were used to find a range of possible flow rates. HW=l30 is a conservative value for both the existing Watts Bar Fossil Plant piping, and the new SCCW piping.
4.1.3 The entire length of SCCW piping is modeled as straight pipe runs, except where fittings are included. There are negligible head losses across the joints, straight or mitered, since the joints are grouted to create smooth transitions from one piping section to another.
4.1.4 The following nomenclature is used for piping lengths: 1+10, where the "I" represents "hundreds", and the "1 0" represents "tens".
4.1.5 The centerline elevations of the piping is used as node elevations in EZFLOW.
4.1.6 The supply line goes from the Watts Bar Lake to the Unit 2 Cooling Tower (the layout of Figure 1 is in the opposite direction). The discharge line goes from the Unit I Cooling Tower to the Energy Dissipater. The initial lines sizes used in the EZFLOW analyses for the supply and discharge are:
Supply Line:
96" to 108" Discharge Line:
60" to 72" 4.1.7 The flow rate supplied to the Unit 2 Cooling Tower is equal to the flow rate discharged from the Unit I Cooling Tower.

MDNI027-980006 4.0 ASSUMPTIONS (continued) 4.2 RESERVOI RS 4.2.1 Watts Bar Lake, Unit I and 2 weir collection basins (weirs), and the Energy Dissipater are considered reservoirs.
4.2.2 The flow paths between Watts Bar Lake and the Intake Screen House, and between the Unit I & 2 Cooling Towers and SCCW piping (the weirs) are modeled as an 144" (12') diameter, 1' long vertical pipes ("dummy" links).
This was done for the following reasons:
A.
To ensure that there are minimal head losses between the water surfaces and the pipes' entrances/exits, and B.
To ensure that the entrances/exits of the piping system have the correct static head associated with difference in elevation between the water surfaces and the pipes' entrances/exits.
4.2.3 Watts Bar Lake can reach flood level (745') in either the summer or winter months.
4.2.4 The Unit I & 2 weirs are transition structures between the SCCW piping and the Unit I & 2 Cooling Towers, respectively. The Unit l& 2 Cooling Towers both have a water elevation of 730'.
4.2.5 The Unitrl & 2 Cooling Towers are the same temperature as the inlets to the Main Condenser.
4.2.6 The Unit I weir water surface elevation is the same as the top invert of the discharge pipe entrance at the Unit I weir. The Unit I weir water elevation is 730' for flood mode; 730' is the Unit 1 Cooling Tower water elevation.
4.2.7 The Unit 2 weir's outlet elevation is always 73 '; this elevation is V above the Unit 2 Cooling Tower water elevation. The "dummy" link, that represents the Unit 2 weir, dumps into the Unit 2 Cooling Tower. This is done to eliminatethe possibility of siphoning water from the Unit 2 Cooling Tower in the event there is a break in the supply line between the supply valve and Unit 2 weir.
4.2.8 The Energy Dissipater is modeled as a reservoir whose elevation is the same as the discharge pipe's centerline at that location. The Energy Dissipater's elevation is 705'.

4.3.2 TRASH RACKS 4.3.2.1 The trash racks are modeled as grillage with square edges.
4.3.2.2 The trash racks are not at an incline.
4.3.3 SLUICE GATES 4.3.3.1 The sluice gates are rectangular, metal gates on the inlet and outlet sides of the traveling water screens. The sluice gates are modeled as fully opened gate valves.
4.3.4 TRAVELING WATER SCREENS 4.3,4.1 The traveling water screens are modeled as 6' foot wide sections of 14 Gauge (0.080 diameter) screen cloth with 3/8" square openings.
4.3.4.2 The height of the traveling water screens varies with the water level in the Watts Bar Lake (See Table 3).
4.3.4.3 The screen cloth is 50% clean.
4.3.4.4 At the Nominal Winter Level of 738', the traveling water screens have the same pressure drop as the Summer Level of 740.5' (See Table 3).

4.0 ASSUMPTIONS (continued) 4.4 TRANSITION CONDUIT 4.4.1 The Transition Conduit is divided into two consecutive transitional segments. The first transitional segment (TSI) is from Station 1+80 to 1+94, and the second transitional segment (TS2) is from 1+94 to 2+00.
TSI and TS2 both consist of two, side by side conduits that are assumed to be identical (Ref. 5.9.5).
4.4.2 TS I decreases in height, while it increases in width. These simultaneous changes are uniform throughout this conduit segment, and the conduit remains rectangular in shape (See Figure 7).
4.4.3 TS2 gradually transitions from rectangular conduit to circular conduit. TS2 conduit is modeled as "duct," with height and width dimensions, until the cross-sectional area becomes more circular, then the conduit is modeled as regular circular pipe (See Figure 8).
4.5 VALVES 4.5.1 The motor-operated valves used in the SCCW piping are generalized symmetric butterfly valves (Standard 3.1).
4.5.2 These valves are used to throttle the flow in the supply and bypass lines, and for isolation in all three lines.

MDN1027-980006 7.0 METHODOLOGY AND COMPUTATIONS 7.1 TRASH RACKS MODELING (Refer to Figure 5)
Each of the Intake Screen House bays has a trash rack. The trash rack is approximately 21' high and 9.5' wide. It is composed of vertical bars that are 5" wide and 3/8" thick, and are spaced 3" on centers. Since EZFLOW does not have a default component to match the trash rack, a head loss coefficient, K, has to be determined. In order to model the trash rack, first, it is assumed that the trash rack is grillage with square edges. To compute the number of bars and spaces, the width of the trash rack was divided by 3":
(9.5') e (12) = 114"/ 3" = 38 bars and spaces The total surface area of a trash rack is:
Total Surface Area = (21') * (9.5') = 199.5 ft' = 200 fte The bars' collective surface area is:
Bar Surface Area=(38 bars) * (21') o (3/8")112 = 24.94 ft - 25 ftW Therefore, the flow area of a trash rack is:
Flow Area - Total Surface Area - Bar Surface Area 200 ft - 25 fe = 175 ft' The percentage of flow area to total surface area is:
Flow Area / Total Surface Area = 175 fl 2200 ftr = 87.5%
The Flow Area is reduced to 80% to account for any structural support and possible debris against the trash rack.
The second part of modeling a trash rack uses the % Flow Area; % Flow Area is represented by a = 80%. The cross-sectional area between the bars is used to find a head loss coefficient, K. The cross-sectional area between the area is 2-5/8" wide, and 5" deep (5" is the width of the bars). Using Table 6.2 in Ref. 5.5, the dimensions of the cross-sectional area are:
a 5" and b 2-5/8" The above dimensions are used to calculate the hydraulic diameter, D, of the cross-sectional area.:

The sluice gates in the Intake Screen House are metal, rectangular openings on the inlet and outlet sides of the traveling water screens. Since EZFLOW does not model rectangular valves, the sluice gates are modeled as fully open gate valves. In order to determine a head loss coefficient, K, for the sluice gate, the cross-sectional is found. The sluice gate is 6' (72") wide and 8' (96") high. Therefore, the cross-sectional area is:
A=w*h A - 72"
- 96" = 6912 in2 The cross-sectional area of the rectangular shape is used to find the diameter of a circle that would have the same area. For a circle:
A= nr2 r =(A / ir) r r
(6912 in' /,a)
=46.91 The diameter of the gate valve would be approximately 94". From Ref. 5.6 page A-23, the fully turbulent friction factor, ft, for 94" commercial steel pipe is fT = 0.009.
Also, from Ref. 5.6 page A-27, the head loss coefficient is:
K-8 f-K = 8
- 0.009 K = 0.072 K = 0.072 is used for the head loss coefficient for the sluice gates in the EZFLOW analyses.

The height of the water on the traveling water screens is determined by:
Height = Water Bar Lake Lvi. - 710' (Intake Screen House floor elev.)
The height is the converted to inches to be input into EZFLOW. The centerline elevation of the Traveling Water Screens is determined by:

The complete transition happens within a horizontal span of approximately 14'. This span is divided into 4 - 3.5' horizontal sections. Furthermore, the height decreases from I 1.5' to 6.5', and increases in width from 3.25' to 5.6'. The overall differences of the height and the width are divided into four equal parts to find the heights and widths for the intermediate nodes.

The second transitional segment (TS2) continues from TSI. There are two separate conduits in TS2, also. There are seven nodes in each conduit of TS2; the nodes begin with 41A & 41B, and end with 50A and 50B, respectively.
Conduit A 41A 42A 43A 44A 45A 46A 50A Conduit B 41B 42B 43B 44A 45B 46B 50A Unlike TS 1 TS2 remains at a constant floor and centerline elevation:
Floor Elev. = 714.76', c = 718.01' The inside shape of the conduit changes from a rectangular shape to a circular shape. TS2 transitions over a span that is approximately 6.5'. The segment is divided into seven lengths: six V' lengths, and one 6" length.
In order to model TS2, the height, width, diameter (for circular sections), floor elevation, centerline elevation (c), and cross-sectional area are needed for each segmented length. The cross-sectional area is needed to model reducers, since the cross-sectional areas are changing from node to node.
The areas of the TS2 sections are irregular. They are in the shape of rectangles with rounded comers. The corners increase in radial length in order to change from a rectangular shape to a circular shape. Figure 8 gives the radius of curvature for the comers of each section (See comer and trapezoid nomenclature). The cross-sectional area is found for each section by using the area formulas for trapezoids, and circles in combination. After the area is found, it used to model a rectangular conduit whose height is 6.5' and whose width is determined by dividing the area by the height. For the sections that are more circular in shape, the area is found in the same manner, however, the area is then divided by pi (n) and the diameter determined.

THE SIZING OF THE SUPPLEMENTAL CONDENSER COOLING WATER (SCCW) SYSTEM SUPPLY, DISCHARGE AND BYPASS LINES DOCUMENT ID:
MDN1027-980006 7.0 METHODOLOGY AND COMPUTATIONS (continued) 7.6 EZFLOW METHODOLOGY 7.6.1 GENERAL 7.6.1.1 The total length of piping between two nodes, including the fittings lengths, is used to model a link in EZFLOW. Piping details are modeled using components listed in the EZFLOW program.
Components that are not listed in EZFLOW are modeled using a head loss coefficient, K, or a flow rate and its corresponding pressure drop.
7.6.1.2 The nodes for the piping layout are placed where there are changes in the slope of the pipe, Ref. 5.7 provides these points in the piping layout.
7,6.1.3 K, head loss coefficient, is used to model the three butterfly valves in the SCCW.
7.6.1.4 The flow rates for the SCCW are gravity driven.
7.6.1.5 HW=130 and HW= 150 are used for the concrete duct/piping.
These Hazen-Williams factors provide flow rates that range from conservative to the possible highest flow rate that may be passed through the SCCW at particular Watts Bar Lake elevations.
7.6.2 PIPE SIZING & BYPASS LINE LOCATION 7.6.2.1 The SCCW consists of three lines: supply, discharge and bypass lines. The supply line runs from the Intake Screen House to the Unit 2 Cooling Tower. The discharge line runs from the Unit I Cooling Tower to the Energy Dissipater. The bypass line connects the supply and discharge lines at a location near the Cooling Towers.
SHEET 28 of 93 WATTS BAR NUCLEAR PLANT - UNIT I 7.0 METHODOLOGY AND COMPUTATIONS (continued) 7.6.2.2-The supply and discharge line are modeled separately. The supply line is modeled incorporating all six bays of the Intake Screen House. The supply line has to pass at least 135,000 gpm when the Watts Bar Lake was at 740.5'. 108" is initially used as the diameter of the supply l ine. Since a pipe diameter of 108" passes more than the required amount of flow, the diameter of the supply line is reduced by 6", and the flow rate is calculated again. This reduction in pipe diameter continues until a flow rate of at least 135,000 gpm, with a marginal excess of flow (about 10,000 gpm), is achieved.
7.6.2.3 The discharge line is sized in a similar manner as the supply line.
72" is initially used as the diameter of the discharge line. The discharge line has to pass the flow calculated for the supply line when Watts Bar Lake elevation is 740.5'. An additional consideration is the capability of the discharge line to pass the supply flow if Watts Bar Lake reaches flood level of 745'. The 72" discharge line sufficiently passes the supply flow rate at 740.5', but does not pass the flood flow rate at 745'. The diameter of the discharge line is increased by 6" until it passes the flood flow rate at 74 5'.
7.6.2.4 The supply and discharge lines are connected by the bypass line to make a complete system. The bypass line is located between the supply and discharge lines near the Unit 2 Cooling Tower. The bypass line is optimized to a length that would be sufficient to locate a butterfly valve within the line, and minimize the head losses due to the piping length. The bypass line is sized to divert approximately 40% of the supply flow during the winter months.
7.6.3 VALVE LOCATIONS 7.6.3.1 The motor-operated butterfly valves are located in close proximity to the bypass line to facilitate electrical connections for all three valves. The valves are first placed in estimated locations, and the definite locations are to be determined later. All three valves are installed with the fully open head loss coefficient of K =0.55.

MDNI027-980006 7.0 METHODOLOGY AND COMPUTATIONS (continued) 7.6.3.2 After the last profiles for the supply and discharge piping were established (Figure 1), the valves are placed at least 8 pipe diameters, and in most cases 10 pipe diameters, from the next piping components to minimize the turbulence affects on the valves.
7.6.4 VALVE THROTTLE POSITIONS 7.6.4.1 The valves are incorporated into the three lines, and the K values are set to 0.55, the fully open position. In order to achieve a particular flow rate, the K for any of the valves can be changed, thus simulating the valve being throttled at various open angles.
(See Attachment 4 for the K-to-open angle chart) 7.6.4.2 Before computing the summer supply flow, the flow in the bypass line is fixed to zero. The bypass line is not modeled to be in operation during summer months. The summer supply flow is then computed to ensure that at least the 135,000 gpm continues to be supplied by the SCCW.
7.6.4.3 The discharge valve remains fully open throughout the year. It is not necessary to throttle the discharge valve because the discharge piping is not supposed to control the fnow to the Energy Dissipater.
Furthermore, the discharge line is sized to accommodate more than any amount of flow that can be supplied by the supply line.
7.6.4.4 With the bypass line's flow fixed at zero, the supply valve is throttled, by changing the K value, until it passes the 135,000 gpm to the Unit 2 Cooling Tower. The K value for the supply valve will be denoted by Ks.
7.6.4,5 After Ks is found, the supply valve will remain in this position throughout the year. With Ks held constant, the fixed flow of zero is removed from the bypass line. K9, the K value for the bypass valve, has been previously set to Ka=0.55.

THE SIZING OF THE SUPPLEMENTAL CONDENSER COOLING WATER (SCCW) SYSTEM SUPPLY, DISCHARGE AND BYPASS LINES DOCUMENT ID:
MDNI027-980006 7.0 METHODOLOGY AND COMPUTATIONS (continued) 7.6.4.6 The governing factor for the bypass valve is to throttle the bypass flow to pass approximately 40% of the supply flow during the winter months. K0 is changed, throttling the bypass valve, until 40% of supply flow is passed through the bypass line. As K, is changed, the flow in the discharge line has to be fixed, simultaneously. The flow is fixed immediately downstream of where the bypass line ties into the discharge line. The discharge flow is fixed to equal the supply flow upstream of the bypass line.
Fixing the flow here simulates the two Cooling Towers being connected, therefore, the amount going into the Unit 2 Cooling Tower is equal to the amount discharged from the Unit 1 Cooling Tower. K9 and the discharge fixed flow are change until:
Bypass Flow = 40% of Supply Flow, and Supply from Watts Bar Lake = Discharge to Energy Dissipater 7.6.5 INTAKE SCREEN HOUSE BAYS 7.6.5.1 The SCCW is initially assumed to have all six Intake Screen House bays in operation, and is modeled as such. After inspection, it was determine that it would not be economically feasible to restore all of the traveling water screens. The number of traveling water screens, thus the number of bays, necessary to provide the 135,000 gpm to the SCCW has to be determined.
7.6.5.2 The SCCW begins with 6 bays modeled. The number of bays is reduced by one until a flow rate above 135,000 gpm is maintained, with a margin of excess flow.
7.6.5.3 After the required number of bays is found, Section 7.6.4 is repeated to obtain the new valve throttle positions.

SUMMARY
OF RESULTS 8.1 PIPE SIZING & BYPASS LINE LOCATION 8.1.1 The results of the pipe sizing analyses yield the following diameters for the three lines:
Supply Line Os = 90" (7.5')
Discharge Line
=o 78" (6.5')
Bypass Line
= 42" (3.5')
8.1.2 The bypass line entrance is at Supply Line Station 36+58, and its exit is at Discharge Line Station 10+35 (See Figure 1). The total length of the bypass line is approximately 145'. The bypass line ties into both lines with tees; 900 tee at the supply line, and a 450 tee at the discharge line. In order to create the contour between the supply an discharge lines, a 450 elbow is placed in the bypass line 10' downstream of the 900 tee. The remaining 135' is contoured, and sweeps into the discharge line at the 450 tee. The bypass valve is located approximately 75' downstream of the 450 c-lbow, 8.1.3 The Unit I weir elevation is omitted from Table I for three of the flow conditions. As stated in Section 4.2.6, the Unit I weir elevation is equal to the top invert elevation of the discharge line at its entrance at the Unit I weir. The bottom invert elevation of the discharge line at this station is 719.5' at the Unit 1 weir. The bottom invert elevation, 719.5', plus the discharge line diameter, 6.5', is equal to the top invert elevation, 726'.
8,2 INTAKE SCREEN HOUSE BAYS 8.2.1 Three (3) Intake Screen House bays are required to supply the necessary flow to the SCCW. The flow rates associated with the above supply and discharge pipe diameters, and 3 Intake Screen House bays are listed in Table 7.
8.2.2 The discharge flow rates for the Winter, Nominal Winter and Summer levels are all 176,579 gpm. They are the same because the Unit I weir collection basin is considered to be at a water elevation of 726' for all three conditions. The Unit I weir water elevation remains constant, except for flood conditions; the Unit 1 weir collection basin flood level is 730'.

SUMMARY
OF RESULTS (continued) 8.2.5 Table 10 presents the head loss coefficients and their corresponding open angles for the bypass valve given the K values for the supply and discharge valves in Table 9. Keep in mind that the bypass line is to be used in the winter months only. Therefore, the two elevations that are of concern are Winter and Nominal Winter Levels of 735' and 738', respectively. The bypass line has to bypass approximately 40% of the supply flow. The bold values are the percent of the supply flow that is bypassed.

9.0 CONCLUSION
S 9.1 The SCCW system is sized properly with:
Supply Line:
90" (7.5')
Discharge Line:
78" (6.5')
Bypass Line:
42" (3.5')
Table 7 shows that for elevations 738' and 740.5', the supply line flows approximately 124,000 to 146,000 gpm, respectively. The SCCW will pass the required flow of 115,000 to 135,000 gpm from the Watts Bar Lake to the Watts Bar Nuclear Plant. The 115,000 gpm and 135,000 gpm correspond to the Watts Bar Lake Nominal Winter and Summer levels of 738' and 740.5'.
Table 10 shows that the bypass line flows approximately 40% of the supply flow during the winter months. Therefore, the bypass line is adequately sized for the SCCW system.
9.2 Three bays are necessary to flow 146,000 gpm through the SCCW system. This flow rate is conservatively greater than the i 35,000 gpm that is required.
9.3 The location of the bypass line allows the required 8 pipe diameters from other piping components on either side of the bypass valve. The bypass line accomplishes this requirement with minimal head losses due to the piping length.
9.4 All of the valves are located in close proximity to each other, and in the vicinity of the Unit 2 Cooling Tower. Their exact locations arc on Figure 9.
9.5 Using Hazen-Williams factors of HW=I30 and HW=l50, below are listed the open angle ranges for the supply, and bypass valves. The discharge valve remains fuIlly open.
Supply Valve:
580 -630 Discharge Valve:
900 Bypass Valve:
630 - 900 These supply valve values throttle the flow to 135,000 gpm, while the discharge valve value allows the flow to discharge without restriction. The bypass valve values allows approximately 40% of the supply flow to be divert to the discharge line. These values are well within the range of 30* to 900 for the best operating range for a butterfly valve in nuclear power plant service.

[I RepfyASAP C3 Please Comment RE: Expected Headloss Calculations. Different Water Level, # of Screens. Flow Volume
- Charlie, Following are our Expected Headloss calculations based on the different variables (Water Level, # of Screens, and Flow Volume).
The calculations were based on the following:
- 6 ft. wide steel tray
-14 Gauge (.080 diameter) screen cloth with 3/8" square openings
- Velocity and headloss were calculated at the low water depths I will mail the originals to your attention.
Please feel free to give me a call if you have any questions.
Best regards, A
