TENNESSEE VALLEY AUTHORITY River Operations SUMMER 2010 COMPLIANCE SURVEY FOR WATTS BAR NUCLEAR PLANT OUTFALL 113 PASSIVE MIXING ZONE Prepared by Brandi L. Ruth and Paul N. Hopping Knoxville, Tennessee February 2011

EXECUTIVE

SUMMARY

The National Pollutant Discharge Elimination System (NPDES) Permit No. TN0020168 for Watts Bar Nuclear Plant (WBN) identifies the discharge of water to the Tennessee River from the Supplemental Condenser Cooling Water (SCCW) System as Outfall 113. Furthermore, the permit identifies that when there is no flow released from Watts Bar Dam (WBH), the effluent from Outfall 113 shall be regulated based on a passive mixing zone extending in the river from bank-to-bank and 1,000 feet downstream from the outfall. Compliance with the requirements for the passive mixing zone is to be made by two annual instream temperature surveys---one for winter conditions and one for summer conditions.

Summarized in this report are the measurements, analyses, and results for the passive mixing zone survey conducted for 2010 summer conditions. The survey was conducted on August 25, 2010 between 07:00 CDT and 15:00 CDT (eight hours) and included the collection of temperature data at twelve temporary monitoring stations deployed across the downstream edge of the passive mixing zone during a period of no flow in the river. The data were analyzed to compute three compliance parameters:

the 1-hour average temperature at the downstream edge of mixing zone, Td; the 1-hour average temperature rise from upstream to the downstream edge of the mixing zone, AT; and the 1-hour average temperature rate-of-change at the downstream edge of the mixing zone, TROC. The measured parameters were compared to predicted values from the thermal plume model used by TVA to help determine the safe operation of Outfall 113. The results of the comparisons, in terms of maximum values observed during the no flow event, are as follows:

Parameter Model Measured NPDES Limit Maximum Td 80.1 OF 80.0°F 86.9 0F Maximum AT 2.3 F0 1.5 F° 5.40F Maximum ITROCI 1.5 F°/hour 0.6 F°/hour 3.6 F°/hr As shown, values predicted by the model were equal or larger to those measured in the survey.

Thus, for the conditions of the survey, the plume model was found to be good for enforcing the operation of Outfall 113 at levels of Td, AT, and TROC without exceeding the NPDES limits.

For Td and AT, these results are consistent with those of all the previous surveys for the passive mixing zone. For TROC, however, previous surveys have revealed that the model is capable of underpredicting measured values for TROC by as much as 0.3 F°/hour (e.g., see McCall and Hopping, 2006). Under these conditions, a factor of safety of 0.3 F°/hour is currently used in the plume model for predicting the maximum value of TROC. In this manner, the safe operation of Outfall 113 for the passive mixing zone is evaluated based on a maximum value of TROC of

+/-3.3 F°/hour rather than +/-3.6 FP/hour. This practice will continue until further notice.

SUMMER 2010 COMPLIANCE SURVEY FOR WATTS BAR NUCLEAR PLANT OUTFALL 113 PASSIVE MIXING ZONE INTRODUCTION Outfall 113 for the Watts Bar Nuclear Plant (WBN) includes the discharge of water to the Tennessee River from the Supplemental Condenser Cooling Water (SCCW) system. Due to the dynamic behavior of the thermal effluent in the river, the National Pollutant Discharge Elimination System (NPDES) Permit No. TN0020168 for the plant specifies two mixing zones for Outfall 113--one for active operation of the river and one for passive operation of the river (TDEC, 2010). The passive mixing zone corresponds to periods when the operation of Watts Bar Dam (WBH) produces no flow in the river (i.e., hydropower and/or spillway releases). The dimensions of the passive mixing zone extend from bank-to-bank and downstream 1,000 feet from the outfall.

The active mixing zone applies to all other river flow conditions.

The dimensions of the active mixing zone include the right-half of the river (facing downstream) and extend downstream 2,000 feet from the outfall. The passive and the active mixing zones are illustrated in Figure 1.

Table 1 summarizes the NPDES temperature limits for Outfall 113. The limits apply to both the active and passive mixing zones.

Compliance for the active mixing zone is monitored by permanent instream water temperature stations situated in the right-half of the river. Due to navigation issues associated with placing permanent stations in the left-half of the river, a thermal plume model is used to determine the safe operation of Outfall 113 for the passive mixing zone. To verify the thermal plume model, the NPDES permit specifies that two instream temperature surveys shall be conducted each year-one for winter conditions and one for summer conditions. The purpose of this report is to present the results for the passive mixing zone temperature survey conducted for summer 2010 conditions. The survey was conducted on August 25, 2010 between 07:00 CDT and 15:00 CDT (eight hours) and included the deployment of temporary temperature stations at twelve locations across the downstream edge of the passive mixing zone. Data from these and other monitoring stations were analyzed to obtain measured values for the compliance parameters listed in Table 1 and to compare these with the corresponding values estimated from the SCCW thermal plume model. Summarized herein are descriptions of the survey method, results, and conclusions.

INSTREAM SURVEY The method of conducting the instream survey is the same as that used for the first such survey, performed for winter conditions on May 6, 2005 (McCall and Hopping, 2005). Table 2 provides a summary of the sources of data for the survey. The WBN Environmental Data Station (EDS) provided measurements from existing permanent monitoring stations, including the upstream (ambient) river temperature, river water surface elevation, SCCW effluent temperature, SCCW effluent flow, and air temperature. WaterView, a hydroplant monitoring system, was used to provide measurements for the discharge from WBH.

The effluent plume for Outfall 113 was monitored by deploying twelve temporary monitoring stations at roughly equal intervals across the downstream edge of the passive mixing zone. The temporary water temperature monitoring stations recorded temperature profiles using HOBO water temperature sensors positioned at depths of 0.5, 3, 5, and 7 feet below the water surface.

Shown in Figure 2 is a schematic of the temporary monitoring stations, which included an assembly containing a tire float, a string of HOBO water temperature sensors, and anchor weights. The water temperature sensors have an accuracy of about +0.4 F0 and resolution of about 0.04 F', which is consistent with other temperature measurements used for TVA hydrothermal compliance. The HOBO devices include an internal data acquisition unit and were programmed to collect measurements once per minute. All the temperature probes used in the survey, including both the HOBOs and the thermistors at the permanent EDS monitoring stations, were calibrated by a quality program with equipment traceable to the National Institute of Standards and Technology (NIST). The calibration procedure is summarized in Appendix A.

The temporary monitoring stations were deployed on August 24, several hours before the beginning of the survey, and were retrieved at the end of the survey. A Global Positioning System (GPS) device was used to position the stations along the downstream edge of the passive mixing zone, as shown in Figure 3.

RESULTS River Conditions Figure 4 shows the measured ambient conditions of the river during the survey; including the discharge, water surface elevation, and temperature of the river exiting Watts Bar Dam upstream of the plant. To provide a period of no flow in the river, releases from Watts Bar Dam were suspended between about 07:00 CDT and 15:00 CDT on August 25, a total of eight hours (daytime). When the releases were suspended, the river water surface elevation below WBH slightly dropped, but then slowly increased to 682.5 feet at 11:30 CDT, due to filling from the river downstream. Over the next hour, the elevation slowly decreased, but then between 12:45 CDT and 15:00 CDT, the water surface elevation rapidly decreased and increased for the last two hours of the survey. This was likely due to sloshing in Chickamauga Reservoir from routine hydro peaking at Watts Bar Dam and Chickamauga Dam. The water surface elevation at the end of the survey was 680.8 feet. The ambient river temperature was about 76.5'F at the beginning of the survey and increased to 78.97F by 13:15 CDT, due primarily to solar heating. The above-mentioned sloshing, which moves water in and out of the tailrace area, was probably responsible for the small fluctuations in water temperature observed beginning at about 12:45 CDT. At the end of the survey, the river temperature had decreased to 78. 17F.

SCCW Conditions During the survey, the SCCW system at WBN was thermally loaded and operating in "summer" mode. That is, the system was operating in a manner producing the largest possible heat load to the river. Shown in Figure 5 are the measured conditions of the SCCW system during the survey; including the discharge and temperature of the SCCW effluent. The SCCW discharge fluctuated between approximately 265 cfs and 296 cfs. The average discharge during the survey was about 285 cfs. The SCCW effluent temperature increased throughout the survey from about 80.5'F at the beginning of the survey to about 85.0°F by the end of the survey. This trend coincides with the air temperature, also shown in Figure 5 (i.e., the performance of the Unit I cooling tower is directly related to the air temperature). Relative to the upstream ambient river temperature, the temperature rise of the effluent exiting the SCCW system hovered around 4.07F for the first two hours of the survey, and then slowly increased, reaching 6.97F at the end of the survey.

Effluent Behavior Individual Temperature Stations Shown in Figure 6 are the readings from the HOBO temperature stations at the downstream end of the passive mixing zone. The stations are labeled consecutively from WB 1 to WB 12, with 3

WB I situated near the left shoreline of the river and WB 12 situated near the right shoreline of the river (i.e., facing downstream-see Figure 3). The following behaviors are noted:

Throughout the survey, there was a steady increase in temperature at all stations and depths.

Even in the absence of the thermal effluent from Outfall 113, this is typical of daytime solar heating of the river (e.g., recall that the ambient river temperature increased by about 2.5°F during the survey). It took about three and a half hours for the warmest part of the effluent plume to spread across to the left-hand-side of the river and to the downstream edge of the passive mixing zone. During the first three hours of the survey, there was a slight increase in temperature of about 0.5°F at most stations at depths of 0.5 feet and 3 feet. However, the 5-foot and 7-foot depths remained fairly constant for the first three hours. In the following five hours, the temperature at all stations increased by as much as 3°F at the 0.5-foot depth, and as much as 2°F at the 7-foot depth. A temperature increase of only about 2'F at the 7-foot depth, which is consistent with the daytime solar heating, suggests that for the prevailing conditions of the river and WBN, most of the thermal effluent from Outfall 113 resides in the surface layer of the water column (i.e., the mid and bottom layers of the river are protected).

During the period of no flow, the temperature for WB 12 at the 0.5-foot depth was higher than those for most of the stations. This is because prior to and at the beginning of the period of no flow, the effluent plume from Outfall 113 resided in the extreme fight-hand-side of the river where WB12 was located. Between 13:00 CDT and 14:00 CDT there was a decrease in temperature at WB9 through WB12 as the effluent plume shifted towards and filled the left-hand-side of the river. Reservoir sloshing also may be a contributing factor to this behavior.

But at the end of the survey, the temperature at these stations increased as the thermal front created by plume filling in the left-hand-side of the river finally began to build back into the right-hand-side of the river.

At the end of the survey, the temperatures at the 0.5-foot depth for WB1 through WB7 were approximately 1°F higher than the temperatures for WB8 through WB112. This is because most of the effluent from Outfall 113 resided in the left-hand-side of the river in the surface layer of the water column at temperatures between 81 OF and 82°F. At a depth of 7 feet and below, the maximum temperature is in the neighborhood of 80'F, only about 1.50F above the ambient river temperature.

Distribution Across The Mixing Zone At each HOBO station, the instantaneous compliance temperature was determined by averaging the measurements for the sensors at the 3-foot, 5-foot, and 7-foot depths. Plotted in Figure 7 are the resulting temperatures across the downstream end of the passive mixing zone, measured at 4

the top of each hour from 07:00 CDT to 15:00 CDT on August 25. The following behaviors are noted:

" For the first three hours of the survey, between 07:00 CDT and 10:00 CDT, the temperature at all locations remained fairly constant with only small fluctuations between 0.1 F to 0.2°F.

" By 11:00 CDT, the effluent appears to have reached the downstream end of the passive mixing zone, increasing the temperature (along with solar heating) by about 0.6°F at most locations.

" Over the remainder of the survey, temperatures continued to increase. Between 12:00 CDT and 13:00 CDT, there were small temperature changes of about 0.1'F at WB5 through WB 12. However, at WB 1 through WB4, there were larger increases of almost 0.5°F. At this time, the majority of the thermal effluent resided in the left-hand-side of the river.

" From 13:00 CDT to 14:00 CDT, the river temperature increased an additional 0.5°F at all locations. The effluent still remained on the left-hand-side of the river showing warmer temperatures at WB 1 through WB5.

" By the end of the survey, at 15:00 CDT, the thermal effluent began to shift back toward the right-hand-side of the river with an increase in temperature of about 0.5°F at WB6 through WB9.

Compliance Parameters Since heat from the outfall is distributed across the full width of the river, data from all of the HOBO stations were used to compute the NPDES compliance parameters, which is consistent with the dimensions of the passive mixing zone (e.g., as shown in Figure 1). The compliance parameters examined include those given in Table 1-the temperature at the downstream edge of mixing zone, Td; the temperature rise from upstream to the downstream edge of the mixing zone, AT; and the temperature rate-of-change at the downstream edge of the mixing zone, TROC. The fundamental equations used to compute the compliance parameters are provided in Appendix B, based on the criteria specified in the NPDES permit. The temperature at the downstream end of the mixing zone was determined from the HOBO measurements (i.e., average of sensors at depths 3, 5, and 7 feet for all twelve HOBO stations). The temperature rise was computed as the difference between the temperature at the downstream end of the mixing zone and the upstream temperature measured at Station 30. The temperature rate-of-change was determined by the change in the temperature at the downstream end of the mixing zone from one hour to the next.

The data were averaged over a period of one hour using 15-minute readings, as specified in the NPDES permit, and compared with the WBN thermal plume model. The results are presented in 5

Figure 8, along with the results obtained by the thermal plume model. The following comments are provided.

Temperature at the downstream edge of the passive mixing zone, Td: The maximum 1-hour average Td estimated by the thermal plume model was 80.1°F, whereas the maximum measured value was about 80.0°F. Thus, the model overpredicted the maximum measured Td by 0.1 °F. Compared to the measurements, the increase in river temperature due to the no flow event was predicted to occur much more rapidly by the model. This is because the model assumes impacts due to changes in the river and/or Outfall 113 are fully realized within one hour (i.e., the model time-step); whereas in reality, the actual time for the development of such impacts is much longer, at least for events with little or no river flow.

Both the predictions from the model and measurements from the survey were well below the NPDES limit of 86.9°F.

" Temperature rise, AT: The maximum 1-hour average AT predicted by the plume model was 2.3 FP, whereas the maximum measured value was about 1.5 F0.

Thus, the model overpredicted the maximum measured temperature rise by 0.8 F0. For the reason cited above (i.e., computational time-step of one hour), the model predicted the temperature rise to occur sooner than that found by the measurements.

Both the predictions from the model and measurements from the survey were well below the NPDES limit of 5.4 F0.

" Temperature rate-of-change, TROC: The maximum 1-hour average TROC predicted by the plume model was 1.5 F0/hour, whereas the maximum measured value was about 0.6 F0/hour (absolute values). Thus, the model overpredicted the actual value of the temperature rate-of-change. Both the predictions from the model and measurements from the survey were well below the NPDES limit of +/-3.6 F°/hour.

CONCLUSIONS The survey for 2010 summer conditions was successful in measuring the NPDES water temperature parameters for the Outfall 113 passive mixing zone.

The measurements were compared with values predicted by the thermal plume model that currently is used to judge the safe operation of the SCCW system. Overall, for the conditions of the 2010 summer survey, the model was found to be good in estimating the impact of Outfall 113 on the temperature, Td, temperature rise, AT, and temperature rate-of-change, TROC, at the downstream end of the passive mixing zone. This is because the model overpredicted the maximum value measured for Td, AT, and TROC. Therefore, Outfall 113 can operate at levels of Td, AT, and TROC without exceeding the NPDES limits. For Td and AT, these results are consistent with those for all of the previous surveys for the passive mixing zone.

The same is not true, however, for TROC.

Previous surveys have revealed that the model is capable of underpredicting measured values for TROC by as much as 0.3 F0/hour (e.g., see McCall and Hopping, 2006). Under these conditions, and despite the results summarized herein, a factor of safety of 0.3 F0/hour is used in the plume model for predicting the maximum value of TROC. That is, the safe operation of Outfall 113 for the passive mixing zone will continue to be evaluated based on a maximum value of TROC of

+/-3.3 F0/hour rather than +/-3.6 F°/hour. In general, this action will have only a very slight impact on the SCCW, since the operation of the SCCW tends to be controlled primarily by the NPDES limit for AT, not the limit for TROC.

APPENDIX A (The following information is provided per request of Mike Kelly of TDEC on August 26, 2008)

All sensors used by TVA for monitoring compliance of NPDES water temperature requirements are certified and maintained to meet the following industry and regulatory standards:

" ISO/IEC 17025--Quality assurance requirements for the competence to carry out sampling, testing, and calibrations using standard, non-standard, and laboratory-developed methods (ISO=International Organization for Standardization, IEC=International Electrotechnical Commission).

"1 OCFR50 Appendix B-Quality assurance criteria for design, fabrication, construction, and testing of the structures, systems, and components of nuclear power plants (CFR=Code of Federal Regulations).

40CFR136--Guidelines establishing test procedures for the analysis of pollutants under the Clean Water Act.

" ANSI N45.2. 1971-Quality assurance requirements for Nuclear Power Plants (ANSI=

American National Standards Institute).

" ANSIINCSL Z540-1-1994--General requirements for calibration laboratories and equipment used for measurements and testing (NCSL=National Conference of Standards Laboratories).

The standard used to certify the thermistors for the permanent EDS stations and the temporary HOBO stations is traceable to the National Institute of Standards and Technology (NIST). The standard includes two pieces of equipment-a platinum resistance temperature detector (RTD) manufactured by Bums Engineering, Inc. and an ohmmeter manufactured by Azonix Inc. The latter is used to measure the resistance of the RTD (i.e., the resistance of platinum varies with temperature). The NTIS traceable calibration certificates for the Burns RTDs and the Azonix ohmmeter that were used to calibrate the HOBO probes are provided below. The end result of the RTD calibration is a set of International Temperature Scale 1990 (ITS 90) coefficients that are used to compute water temperature from the measured RTD resistance.

Based on the calibration certificates, the accuracy of the system for the temperature standard is about +/-0.05'F.

The tolerance of the thermistors used for the WBN field survey is about +/-0.4°F, thus providing a calibration test accuracy ratio (TAR) of about 1:8. That is, the accuracy of temperature standard used for the sensor calibrations is 8 times greater than the minimum acceptable field accuracy of temperature sensors.

This is twice the recommended maximum TAR of 1:4 for sensor calibrations.

The TVA procedure to calibrate the HOBO water temperature probes, Instruction No. 450.01-020, is provided below. Briefly, the HOBO probes are immersed in a stirred temperature-controlled water bath along with the standard (i.e., along with the Bums RTD probe). After the bath stabilizes, temperature readings from the HOBO probes are compared to the temperature readings from the standard. Experience has shown that in nearly all cases, the readings from both the HOBO probes and the standard and are essentially constant, so that the 95 percent confidence interval of the readings is diminutive. Under these conditions, the accuracy of each HOBO probe is recorded simply as the difference between the HOBO reading and that of the standard (negative difference = HOBO reading low/below standard, positive difference = HOBO reading high/above standard). The HOBO probes are tested at three temperatures between 30'F and 100lF, covering the range of expected water temperature for natural river conditions.

Specifically, the three temperatures are at about the 10 percent, 50 percent, and 90 percent intervals, or 37'F, 65°F and 93°F, respectively. Any HOBO probe with measured accuracy (i.e.,

difference) in excess of the maximum allowable tolerance of +0.4°F for any one temperature fails the calibration test and is removed from the field survey inventory. In general, based on TVA experience, most HOBO probes that pass the calibration test usually have measured accuracies better than about +/-0.25'F for all three temperatures examined in the bath tests. The calibration certificates for HOBO probes used in field survey summarized herein are provided below. Included are certificates for both the pre-and post-survey calibration tests. A close examination of the certificates shows that all the HOBO probes passed the calibration test both before and after the field survey.

0 Eft. Date 5M19103 Page 3 of 7 1.0 PURPOSE To provide uniform and effective certifications of Hobo Water Temp Pro data acquisition systems meeting the accuracy and performance requirements of TVA's water temperature-monitoring programs. This technical instruction uses the method of comparison with a laboratory standard thermometer.

2.0 SCOPE This instruction applies to the certification of Hobo Water Temp Pro data loggers manufactured by Onset Computer Corporation of Bourne, Massachusetts. The Hobo Water Temp Pro is a data acquisition system containing a temperature sensor, data logger and battery sealed in a sinVge submersible case. The Hobo Water Temp Pro is programmed and data retrieved by use of an infrared interface located in one end of the case. Hobo Water Temp Pros are certified upon receipt from the manufacturer at no greater than 12 month intervals during use or when requested.

3.0

SUMMARY

In this three-point certification systems are tested as actually used over the historical water temperature range of 30' to 100'F and submerged in water. The three test points are 37', 65' and 93'F. The systems are required to perform within Onset Computer Corporation tolerances. System conformity at each temperature point is determined by comparing system temperature, logged by the Hobo Water Temp Pro and a laboratory standard thermometer.

Systems are programmed and submerged with a standard thermometer in a stiffed, temperature-controlled temperature bath. The systems are read after the test by an infrared interface adapter connected to a computer running Onset Computer Corporation's Boxcar Pro software. Traceability of the certification is through the thermometer.

'As-found" certifications are performed on new systems as an acceptance test and on sensors returned from field service. =As-left" certifications are performed before delivery for field service if more than 12 months has elapsed since the last certification. 'As-fonmd( and Xas4ert certifications may be combined on the same record if there is clear indication which type each system is undergoing.

Multiple HOBOs may be certified at the same time in the temperature bath.

8.2 Check the IR interface to verify that it is plugged into the correct serial port on the PC.

Set the correct time on the PC.

8.3 Align the IR port on the Base station with the HOBO Water Temp Pro communications window. Place the logger no further than 4 to 5 inches away from the Base station (see Figure 2) and make sure the IR windows in both devices point at each other. There is a 30' acceptance angle for the IR beam, so some misalignment is acceptable.

0 Eff. Date 5119103 Page 5 of 7 8.4 Start the Onset Box Car Software and select Logger then Hobo Water Temp Pro and Launch.

8.5 The computer will respond with a Est of loggers found. The serial number in this list should match the serial number printed on the side of the logger. If these numbers do not match, click the Refresh button. Record this serial number on the certification form.

Either wait or click the Stop Searching button. Using the mouse select the logger and click Me Launch button.

8.6 After a few seconds the screen will display the status of the HOBO Water Temp Pro.

Record the battery percentage on the certification form.

8.7 Verify that the Hobo is set to Fahrenheit and program it to a recording interval of 0:1:0 for a reading once a minute. Verify that the start logging immediately box is checked and that the set data logger clock with host launch is also checked.

8.8 Using the mouse dick the Launch Immediately button.

8.9 If last HOBO is programrmed dick the DONE button, else select the Launch Another and repeat steps 8.5 through 8.9.

9.0 TEST PROCEDURE/METHOD 9.1 On the certification form record the serial number of the laboratory reference thermometer.

9.2 Place the HOBO Water Temp Pro in the temperature bath, making sure the end opposite the IR vindovs is submerged, and allom the bath to stabilize at 37SF +/-0.5'F on the thermometer. Adjust the bath set point if needed. After the bath reaches the desired temperature allow 20 minutes 'soak time' for the HOBO to reach its final temperature.

9.3 Record the thermometer reading on the certification form and the lime. (The time will be needed to get the correct reading from the HOBO.)

9.4 Repeat steps 9.2 and 9.3 for bath settings of 65.0CF +/- 0.5'F and 93'F +/- 0.5'F.

9.5 Remove the HOBO from the temperature bath and align the IR port on the Base station with the HOBO Water Temp Pro communications window.

SUMMARY

The National Pollutant Discharge Elimination System (NPDES) Permit No. TNO020168 for Watts Bar Nuclear Plant (WBN) identifies the discharge of water to the Tennessee River from the Supplemental Condenser Cooling Water (SCCW) System as Outfall 113. Furthermore, the permit identifies that when there is no flow released from Watts Bar Dam (WBH), the effluent from Outfall 113 shall be regulated based on a passive mixing zone extending in the river from bank-to-bank and 1,000 feet downstream from the outfall. Compliance with the requirements for the passive mixing zone is to be made by two annual instream temperature surveys--one for winter conditions and one for summer conditions.

Summarized in this report are the measurements, analyses, and results for the passive mixing zone survey conducted for 2010 winter conditions. The survey was conducted between 23:00 CST on March 3 and 05:00 CST on March 4 (six hours) and included the collection of temperature data at twelve temporary monitoring stations deployed across the downstream edge of the passive mixing zone during a period of no flow in the river. The data were analyzed to compute three compliance parameters:

the 1-hour average temperature at the downstream edge of mixing zone, Td; the 1-hour average temperature rise from upstream to the downstream edge of the mixing zone, AT; and the 1-hour average temperature rate-of-change at the downstream edge of the mixing zone, TROC. The measured parameters were compared to predicted values from the thermal plume model used by TVA to help determine the safe operation of Outfall 113. The results of the comparisons, in terms of maximum values observed during the no flow event, are as follows:

Parameter Model Measured NPDES Limit Maximum Td 46.1 OF 43.6 0F 86.9 0F Maximum AT 4.4 F0 2.1 F0 5.4 F0 Maximum ITROCI 1.0 F0/hour 1.0 F0/hour 3.6 F°/hr As shown, values predicted by the model were equal or larger to those measured in the survey.

Thus, for the conditions of the survey, the plume model was found to be good for enforcing the operation of Outfall 113 at levels of Td, AT, and TROC without exceeding the NPDES limits.

For Td and AT, these results are consistent with those of all the previous surveys for the passive mixing zone. For TROC, however, previous surveys have revealed that the model is capable of underpredicting measured values for TROC by as much as 0.3 F0/hour (e.g., see McCall and Hopping, 2006). Under these conditions, a factor of safety of 0.3 F°/hour is currently used in the plume model for predicting the maximum value of TROC. In this manner, the safe operation of Outfall 113 for the passive mixing zone is evaluated based on a maximum value of TROC of

+/-3.3 F°/hour rather than +/-3.6 F0/hour. This practice will continue until further notice.

WINTER 2010 COMPLIANCE SURVEY FOR WATTS BAR NUCLEAR PLANT OUTFALL 113 PASSIVE MIXING ZONE INTRODUCTION Outfall 113 for the Watts Bar Nuclear Plant (WBN) includes the discharge of water to the Tennessee River from the Supplemental Condenser Cooling Water (SCCW) system. Due to the dynamic behavior of the thermal effluent in the river, the National Pollutant Discharge Elimination System (NPDES) Permit No. TN0020168 for the plant specifies two mixing zones for Outfall 113--one for active operation of the river and one for passive operation of the river (TDEC, 2004). The passive mixing zone corresponds to periods when the operation of Watts Bar Dam (WBH) produces no flow in the river (i.e., hydropower and/or spillway releases). The dimensions of the passive mixing zone extend from bank-to-bank and downstream 1,000 feet from the outfall.

The active mixing zone applies to all other river flow conditions.

The dimensions of the active mixing zone include the right-half of the river (facing downstream) and extend downstream 2,000 feet from the outfall. The passive and the active mixing zones are illustrated in Figure 1.

Table 1 summarizes the NPDES temperature limits for Outfall 113. The limits apply to both the active and passive mixing zones.

Compliance for the active mixing zone is monitored by permanent instream water temperature stations situated in the right-half of the river. Due to navigation issues associated with placing permanent stations in the left-half of the river, a thermal plume model is used to determine the safe operation of Outfall 113 for the passive mixing zone. To verify the thermal plume model, the NPDES permit specifies that two instream temperature surveys shall be conducted each year-one for winter conditions and one for summer conditions. The purpose of this report is to present the results for the passive mixing zone temperature survey conducted for winter 2010 conditions.

The survey was conducted between 23:00 CST on March 3 and 05:00 CST on March 4 (six hours) and included the deployment of temporary temperature stations at twelve locations across the downstream edge of the passive mixing zone. Data from these and other monitoring stations were analyzed to obtain measured values for the compliance parameters listed in Table 1 and to compare these with the corresponding values estimated from the SCCW thermal plume model. Summarized herein are descriptions of the survey method, results, and conclusions.

INSTREAM SURVEY The method of conducting the instream survey is the same as that used for the first such survey, performed for winter conditions on May 6, 2005 (McCall and Hopping, 2005). Table 2 provides a summary of the sources of data for the survey. The WBN Environmental Data Station (EDS) provided measurements from existing permanent monitoring stations, including the upstream (ambient) river temperature, river water surface elevation, SCCW effluent temperature, SCCW effluent flow, and air temperature. WaterView, a hydroplant monitoring system, was used to provide measurements for the discharge from WBH.

The effluent plume for Outfall 113 was monitored by deploying twelve temporary monitoring stations at roughly equal intervals across the downstream edge of the passive mixing zone. The temporary water temperature monitoring stations recorded temperature profiles using HOBO water temperature sensors positioned at depths of 0.5, 3, 5, and 7 feet below the water surface.

Shown in Figure 2 is a schematic of the temporary monitoring stations, which included an assembly containing a tire float, a string of HOBO water temperature sensors, and anchor weights. The water temperature sensors have an accuracy of about +/-0.4 F0 and resolution of about 0.04 F', which is consistent with other temperature measurements used for TVA hydrothermal compliance. The HOBO devices include an internal data acquisition unit and were programmed to collect measurements once per minute. All the temperature probes used in the survey, including both the HOBOs and the thermistors at the permanent EDS monitoring stations, were calibrated by a quality program with equipment traceable to the National Institute of Standards and Technology (NIST). The calibration procedure is summarized in Appendix A.

The temporary monitoring stations were deployed on March 3, several hours before the beginning of the survey, and were retrieved at the end of the survey. A Global Positioning System (GPS) device was used to position the stations along the downstream edge of the passive mixing zone, as shown in Figure 3.

RESULTS River Conditions Figure 4 shows the measured ambient conditions of the river during the survey; including the discharge, water surface elevation, and temperature of the river exiting Watts Bar Dam upstream of the plant. To provide a period of no flow in the river, releases from Watts Bar Dam were suspended between about 23:00 CST on March 3 and 05:00 CST on March 4, a total of six hours (nighttime). When the releases were suspended, the river water surface elevation below WBH first dropped, but then slowly increased, due to filling from the river downstream. The ambient river temperature was about 41.6°F at the beginning of the survey, and in effect, remained steady throughout the survey.

SCCW Conditions During the survey, the SCCW system at WBN was thermally loaded and operating in "summer" mode That is, the system was operating in a manner producing the largest possible thermal load to the river. Shown in Figure 5 are the measured conditions of the SCCW system during the survey; including the discharge and temperature of the SCCW effluent. The SCCW discharge fluctuated between approximately 184 cfs and 207 cfs. The average discharge during the survey was about 195 cfs. At the beginning of the survey, the SCCW effluent temperature decreased from about 63.0°F at the beginning of the survey to about 61.8°F at the 01:00 CST. The temperature then increased throughout most of the remaining part of the survey, reaching about 64.1°F at the end of the survey. This trend coincides with the air temperature, also shown in Figure 5 (i.e., the performance of the Unit 1 cooling tower is directly related to the air temperature). Relative to the upstream river temperature, the temperature rise of the effluent exiting the SCCW system decreased from about 21.4°F at the beginning of the survey to about 20.2'F at 01:00 CST, then increased to about 22.6°F at the end of the survey.

Effluent Behavior Individual Temperature Stations Shown in Figure 6 are the readings from the HOBO temperature stations at the downstream end of the passive mixing zone. The stations are labeled consecutively from WB1 to WB12, with WB 1 situated near the left shoreline of the river and WB 12 situated near the right shoreline of the river (i.e., facing downstream-see Figure 3). The following behaviors are noted:

The temperatures for WB 1 through WB7, located in the left-hand part of the river, were fairly steady for about the first 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months of the survey, at all the compliance depths of 0.5, 3, 5, and 7 feet. In the following 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months , the temperatures for these stations increased by about 4.50F at the 0.5-foot depth and about 2'F at the 7-foot depth. This likely corresponds to the 3

leading edge of the effluent plume from Outfall 113 as it migrated across the river during the period of no flow. That is, for this event, it took about 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months for the warmest part of the effluent plume to spread across to the left-hand-side of the river and to the downstream edge of the passive mixing zone. A temperature increase of only about 2'F at the 7-foot depth demonstrates that for the prevailing conditions of the river and WBN, most of the thermal effluent from Outfall 113 resides in the surface layer of the water column (i.e., the mid and bottom layers of the river are protected).

At the beginning of the period of no flow, the temperatures for WB I1 and WB12 were higher than those for WB1 through WB7. This is because prior to and at the beginning of the period of no flow, the effluent plume from Outfall 113 resided in the extreme right-hand-side of the river where these stations were located. Afterwards, the temperatures for WB 11 and WB 12 cooled as the effluent plume shifted towards and filled the left-hand-side of the river. But at the end of the survey, the temperature at these stations increased as the thermal front created by plume filling in the left-hand-side of the river finally began to build to the right-hand-side of the river.

The temperatures for WB8 through WB10 exhibited an increase in temperature within the first 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of the period of no flow, followed by a decrease in temperature, particularly at the 0.5 and 3 feet depths. This is due to the transport of effluent plume across the mixing zone from the right-hand-side to the left-hand-side of the river. Later, in the sixth and final hour of the period of no flow, the temperatures for these stations again increased as the thermal effluent began to build back across the river from the left-hand-side to the right-hand-side.

" At the end of the survey, the effluent from Outfall 113 was well distributed across the river, with most of the effluent residing in the surface layer of the water column at temperatures between 44'F and 46'F. At a depth of 7 feet and below, the maximum temperature is in the neighborhood of 43°F, only about 1.5'F above the ambient river temperature.

Distribution Across The Mixing Zone At each HOBO station, the instantaneous compliance temperature was determined by averaging the measurements for the sensors at the 3-foot, 5-foot, and 7-foot depths. Plotted in Figure 7 are the resulting temperatures across the downstream end of the passive mixing zone, measured at the top of each hour from 23:00 CST on March 3 to 05:00 CST on March 4. The following behaviors are noted:

At the beginning of the survey (23:00 CST of March 3), most of the effluent plume from Outfall 113 resided in the right-hand-side of the river, between WB 11 and WB 12. This is 4

noted by the higher water temperatures in this area. As the survey progressed, the water temperature for these stations slowly decreased as the thermal effluent shifted towards the left-hand-side of the river.

In contrast, for the first 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months of the survey (until about 02:00 CST of March 3), there was very little change in water temperature in the left-hand-side of the river, between WB 1 and WB7. After 02:00 CST, the water temperatures in this area increased as the effluent plume spread into the left-hand-side of the river at the downstream edge of the passive mixing zone.

Between 02:00 CST and 05:00 CST, water temperatures in this area increased as much as 3 F'. By 05:00 CST, the effluent plume had spread back across to the right-hand-side of the river, reaching WB 12.

Compliance Parameters Since heat from the outfall is distributed across the full width of the river, data from all of the HOBO stations were used to compute the NPDES compliance parameters, which is consistent with the dimensions of the passive mixing zone (e.g., as shown in Figure 1). The compliance parameters examined include those given in Table 1-the temperature at the downstream edge of mixing zone, Td; the temperature rise from upstream to the downstream edge of the mixing zone, AT; and the temperature rate-of-change at the downstream edge of the mixing zone, TROC. The fundamental equations used to compute the compliance parameters are provided in Appendix B, based on the criteria specified in the NPDES permit. The temperature at the downstream end of the mixing zone was determined from the HOBO measurements (i.e., average of sensors at depths 3, 5, and 7 feet for all twelve HOBO stations). The temperature rise was computed as the difference between the temperature at the downstream end of the mixing zone and the upstream temperature measured at Station 30. The temperature rate-of-change was determined by the change in the temperature at the downstream end of the mixing zone from one hour to the next.

The data were averaged over a period of one hour using 15-minute readings, as specified in the NPDES permit, and compared with the WBN thermal plume model. The results are presented in Figure 8, along with the results obtained by the thermal plume model. The following comments are provided.

5

Temperature at the downstream edge of the passive mixing zone, Td: The maximum 1-hour average Td estimated by the thermal plume model was 46.1°F, whereas the maximum measured value was about 43.6 0F. Thus, the model overpredicted the maximum measured Td by 2.5'F. Compared to the measurements, the increase in river temperature due to the no flow event was predicted to occur much more rapidly by the model. This is because the model assumes that impacts due to changes in the river and/or Outfall 113 are fully realized within one hour (i.e., the model time-step); whereas in reality, the actual time for the development of such impacts is much longer, at least for events with little or no river flow.

Both the predictions from the model and measurements from the survey were well below the NPDES limit of 86.9°F.

Temperature rise, AT: The maximum 1-hour average AT predicted by the plume model was 4.4 F0, whereas the maximum measured value was about 2.1 F0.

Thus, the model overpredicted the maximum measured temperature rise by 2.3 F0. For the reason cited above (i.e., computational time-step of one hour), the model predicted the temperature rise to occur sooner than that found by the measurements.

Both the predictions from the model and measurements from the survey were well below the NPDES limit of 5.4 F0.

Temperature rate-of-change, TROC: The maximum 1-hour average TROC predicted by the plume model was 1.0 F0/hour, whereas the maximum measured value was about 1.0 F°/hour (absolute values). Thus, the model predicted the actual value of the temperature rate-of-change. Both the predictions from the model and measurements from the survey were well below the NPDES limit of +3.6°F.

CONCLUSIONS The survey for 2010 winter conditions was successful in measuring the NPDES water temperature parameters for the Outfall 113 passive mixing zone.

The measurements were compared with values predicted by the thermal plume model that currently is used to determine the safe operation of the SCCW system. Overall, for the conditions of the 2010 winter survey, the model was found to be good in estimating the impact of Outfall 113 on the temperature, Td, temperature rise, AT, and temperature rate-of-change, TROC, at the downstream end of the passive mixing zone. This is because the model overpredicted the maximum value measured for Td and AT and predicted the maximum value measured for TROC. Therefore, Outfall 113 can operate at levels of Td, AT, and TROC without exceeding the NPDES limits. For Td and AT, these results are consistent with those for all of the previous surveys for the passive mixing zone.

The same is not true, however, for TROC. Previous surveys have revealed that the model is capable of underpredicting measured values for TROC by as much as 0.3 F°/hour (e.g., see McCall and Hopping, 2006). Under these conditions, and despite the results summarized herein, a factor of safety of 0.3 F°/hour is used in the plume model for predicting the maximum value of TROC. That is, the safe operation of Outfall 113 for the passive mixing zone will continue to be evaluated based on a maximum value of TROC of +/-3.3 F°/hour rather than +/-3.6 F°/hour. In general, this action will have only a very slight impact on the SCCW, since the operation of the SCCW tends to be controlled primarily by the NPDES limit for AT, not the limit for TROC.

The standard includes two pieces of equipment-a platinum resistance temperature detector (RTD) manufactured by Burns Engineering, Inc. and an ohmmeter manufactured by Azonix Inc. The latter is used to measure the resistance of the RTD (i.e., the resistance of platinum varies with temperature). The NTIS traceable calibration certificates for the Burns RTDs and the Azonix ohmmeter that were used to calibrate the HOBO probes are provided below. The end result of the RTD calibration is a set of International Temperature Scale 1990 (ITS 90) coefficients that are used to compute water temperature from the measured RTD resistance.

Based on the calibration certificates, the accuracy of the system for the temperature standard is about +/-0.05°F.

The tolerance of the thermistors used for the WBN field survey is about +/-0.4°F, thus providing a calibration test accuracy ratio (TAR) of about 1:8. That is, the accuracy of temperature standard used for the sensor calibrations is 8 times greater than the minimum acceptable field accuracy of temperature sensors.

This is twice the recommended maximum TAR of 1:4 for sensor calibrations.

17

The TVA procedure to calibrate the HOBO water temperature probes, Instruction No. 450.01-020, is provided below. Briefly, the HOBO probes are immersed in a stirred temperature-controlled water bath along with the standard (i.e., along with the Bums RTD probe). After the bath stabilizes, temperature readings from the HOBO probes are compared to the temperature readings from the standard. Experience has shown that in nearly all cases, the readings from both the HOBO probes and the standard and are essentially constant, so that the 95 percent confidence interval of the readings is diminutive. Under these conditions, the accuracy of each HOBO probe is recorded simply as the difference between the HOBO reading and that of the standard (negative difference = HOBO reading low/below standard, positive difference = HOBO reading high/above standard). The HOBO probes are tested at three temperatures between 30'F and 100°F, covering the range of expected water temperature for natural river conditions.

Specifically, the three temperatures are at about the 10 percent, 50 percent, and 90 percent intervals, or 37'F, 65'F and 93'F, respectively. Any HOBO probe with measured accuracy (i.e.,

difference) in excess of the maximum allowable tolerance of +/-0.4'F for any one temperature fails the calibration test and is removed from the field survey inventory. In general, based on TVA experience, most HOBO probes that pass the calibration test usually have measured accuracies better than about +0.25°F for all three temperatures examined in the bath tests. The calibration certificates for HOBO probes used in field survey summarized herein are provided below. Included are certificates for both the pre-and post-survey calibration tests. A close examination of the certificates shows that all the HOBO probes passed the calibration test both before and after the field survey.

TITLE: Certification of HOBO Water Temp Pro Data Acquisition Instruction No.

450.01-020 Systems H20-O01 Rev.

0 Eft. Date 5&19103 Page 3 of 7 1.0 PURPOSE To provide uniform and effective certifications of Hobo Water Temp Pro data acquisition systems meeting the accuracy and perfomance requirements of TVA's water temperature-monitoring programs. This technical instruction uses the method of comparison with a laboratory standard thermometer.

2.0 SCOPE This instruction applies to the certification of Hobo Water Temp Pro data loggers manufactured by Onset Computer Corporation of Boume, Massachusetts. The Hobo Water Temp Pro is a data acquisition system containing a temperature sensor, data logger and battery sealed in a single submersible case. The Hobo Water Temp Pro is programmed and data retrieved by use of an infrared interface located in one end of the case. Hobo Water Temp Pros are certified upon receipt from the manufacturer at no greater than 12 month intervals during use or when requested.

3.0

SUMMARY

In this three-point certification systems are tested as actually used over the historical water temperature range of 30' to 1 00'F and submerged in water. The three test points are 37', 65' and 93cF. The systems are required to perform within Onset Computer Corporation tolerances. System conformity at each temperature point is determined by comparing system temperature, logged by the Hobo Water Temp Pro and a laboratory standard thermometer.

Systems are programmed and submerged with a standard thermometer in a stirred, temperature-controlled temperature bath. The systems are read after the test by an infrared interface adapter cornected to a computer running Onset Computer Corporation's Boxcar Pro softwvare. Traceability of the certification is through the thermometer.

"As-found" certifications are performed an new systems as an acceptance test and on sensors returned from field service. 'As-left' certifications are performed before delivery for field service if more than 12 months has elapsed since the last certification. *As-found' and 'as-tef certifications may be combined on the same record if there is clear indication which type each system is undergoing.

Multiple HOBOs may be certified at the same time in the temperature bath.

8.2 Check the IR interface to verify that it is plugged into the correct serial port on the PC.

Set the correct time on the PC.

8.3 Align the IR port on the Base station with the HOBO Water Temp Pro communications window. Place the logger no further than 4 to 5 inches away from the Base station (see Figure 2) and make sure the IR windows in both devices point at each other. There is a 30' acceptance angle for the IR beam, so some misalignment is acceptable.

0 Eft. Date 5119J03 Page 5 of 7 8.4 Start the Onset Box Car Software and select Logger then Hobo Water Temp Pro and Launch.

8.5 The computer will respond with a Fist of loggers found. The serial number in this list should match the serial number printed on the side of the logger. If these numbers do not match, click the Refresh button. Record this serial number on the certification form.

Either wait or click the Stop Searching button. Using the mouse select the logger and click the Launch button.

8.6 After a few seconds the screen will display the status of the HOBO Water Temp Pro.

Record the battery percentage on the certification form.

8.7 Verify that the Hobo is set to Fahrenheit and program it to a recording interval of 0:1:0 for a reading once a minute. Verify that the start logging immediately box is checked and that the set data logger clock with host launch is also checked.

8.8 Using the mouse click the Launch Immediately button.

8.9 If last HOBO is programmed click the DONE button, else select the Launch Another and repeat steps 8.5 through 8.9.

9.0 TEST PROCEDUREIMETHOD 9.1 On the certification form record the serial number of the laboratory reference thermometer.

9.2 Place the HOBO Water Temp Pro in the temperature bath, making sure the end opposite the IR windows is submerged, and allow the bath to stabilize at 370 F +/-0.5'F on the thermometer. Adjust the bath set point if needed. After the bath reaches the desired temperature allow 20 minutes 'soak time' for the HOBO to reach its final temperature.

9.3 Record the thermometer reading on the certification form arid the time. IThe time will be needed to get the correct reading from the HOBO.)
