FPL Turkey Point Comprehensive Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - March 2016 Section 5 May 2015 and encompasses the Post-Uprate period. This period of time includes the increases in both CCS salinity and temperature (that were observed to begin in fall 2013), the drop in salinity due to the addition of L-31E water in the fall of 2014, and the subsequent rebound in salinity in the CCS.

The conceptual p model and associated calculations are ppredominantly y unchanged since last presented in the 2012 Comprehensive Pre-Uprate Monitoring Report. As such, only a brief summary of the model is provided below. In addition, model results and corresponding conclusions regarding the operation of the CCS, based on the current calibrated water and salt balance model, are provided herein. The Excel spreadsheet that comprises the model is provided in a separate data file.

5.3.1 Model Summary As Figure 5.3-1 depicts, the water balance of the control volume (i.e., the CCS) is comprised of seepage (lateral through the sides and vertical through the bottom), blowdown (additional water pumped from other units to the CCS), precipitation (including runoff from earth berms between canals), and evaporation. Other than evaporation and precipitation, these are the same mechanisms by which salt flows into and out of the CCS. The means by which water and/or salt is transferred (e.g., seepage, evaporation) is calculated using various equations provided in the 2012 Comprehensive Pre-Uprate Monitoring Report. Calculations were performed for a 57-month period from September 2010 through May 2015. Average flows of water and salt into and out of the control volume were calculated for each day of this period using hydrologic, water quality, and meteorological data measured within, beneath, and adjacent to the CCS. The average daily flows were summed to estimate the amount of water and salt that enters or exits the control volume during each month and the entire 57-month period. These calculations demonstrate and validate the conceptual model of the CCS and, in so doing, illustrate the hydrologic mechanisms by which the CCS functions.

Calculated water flows are reported in 106 gallons per day (mgd). The mass flux into or out of the control volume is calculated by multiplying the volumetric flow by the salinity of the body of water from which the water is flowing. Salinity from the same groundwater and surface water monitoring stations used in the 2012 Comprehensive Pre Uprate Report (FPL 2012a) were used in the calculations and reported in the practical salinity scale (PSS-78), which is equivalent to grams per liter (g/L). Calculated mass fluxes are reported in thousands of pounds per day (lb x 1,000/day).

Over time, the gain/loss of water and salt mass within the control volume results in a change in the control volumes water and salt mass storage. Increased water storage, for instance, occurs when more water enters the control volume than exits. Storage, then, can be estimated by summing all of the components of the water (and salt) balance. When the net flow is positive (into the control volume) during a specified period of time, the storage of control volume increases. Conversely, a net negative (out of the control volume) flow implies a decrease in storage during a specified time period.

FPL Turkey Point Comprehensive Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - March 2016 Section 5 Another manner in which a change in storage can be estimated relies on direct measurements of water elevations and salinities within the control volume. A change in water elevation within the control volume can be calculated as a difference between water elevations at the beginning and end of a specified time period. The product of this change in water elevations and the surface area of the control volume provides an estimate of the change in the volume of water contained in the control volume during that period of time. Estimates of daily storage changes derived from this method are used to further calibrate the water and salt balance model to ensure an accurate simulation of temporal trends in CCS water elevation and salinity.

5.3.2 Model Calibration The individual components of the water and salt balance were simulated daily and summed for each month from September 2010 through May 2015, as well as for the collective 57-month period. The individual components of flow are summed in order to calculate a simulated change in volume for each month and for the 57-month period. These simulated changes in storage were compared with observed changes in CCS water and salt storage for each month and the entire calibration period. Errors between the simulated and observed monthly storage changes were minimized by adjusting key variables associated with the flow balance model; this process is called calibration. The calibration process ensures that the model can accurately reflect the average changes in CCS storage over the 57-month time frame while also effectively capturing day-to-day changes in CCS water and mass storage. Calibration of the water and salt balance model was achieved by adjusting hydraulic conductivities of the aquifer materials adjacent to and beneath the CCS that factor into the calculation of seepage to/from groundwater and Biscayne Bay. Additional adjustable parameters include the coefficients in the wind function (FPL 2012a), the amount of runoff that enters the control volume as a percentage of precipitation, the amount of Unit 5 cooling tower water that is lost to evaporation before entering the CCS, and the salinity of the Unit 5 blowdown as a percentage of seawater. The calibrated model parameter values are provided in Table 5.3-1.

The horizontal hydraulic conductivities laterally adjacent to the control volume were calibrated to range between 500 ft/day and 900 ft/day. The calibrated vertical conductivities beneath the control volume ranged from 0.1 ft/day to 4 ft/day. The horizontal hydraulic conductivities of the side faces of the CCS are relatively high due the assumed incising of highly permeable material that underlies the muck and Miami limestone by deeper canals. For the same reason, the northern discharge canals and return canals were calibrated to relatively high vertical hydraulic conductivities (4 ft/day and 3.8 ft/day, respectively). Lower vertical hydraulic conductivities were calibrated for the middle and southern portions of the discharge canals, as well as the southern portion of the return canals (0.1 ft/day).

A notable deviation from the conceptual CCS water and salt flow balance is the recognition of reduced flow in the plant discharge canals. In early 2014, FPL noted that water flow was quite low in some plant discharge canals. In some cases, it was observed that CCS water did not flow in parts of individual canals. The lack of flow in certain individual canals limits the intended function of the CCS as a radiator, such that water preferentially flows through other canals at a faster rate than normal. The greater rate of flow of CCS water in some canals inhibits the 5-7

FPL Turkey Point Comprehensive Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - March 2016 Section 5 process of evaporation and the cooling effect that evaporation provides to the CCS. This phenomenon was simulated by reducing the CCS discharge canals surface area between January 2014 and May 2015 by between 16% and 20%. Though coarse, this approximation accounts for both a physical reduction in surface area as well as the related limits on the evaporative process.

5.3.3 Model Results and Discussion Results of the simulated 57-month water and salt balance model are provided in Tables 5.3-2 and 5.3-3, respectively. Monthly balance results follow in Tables 5.3-4 and 5.3-5. The modeled net flow of water, as calculated by the summing the components of the water balance for the 57-month calibration period, is denoted as the Modeled Change in CCS Storage and was calculated to be an average outflow of 0.22 mgd over the 57-month calibration period (Table 5.3-2). The observed change in storage, which is the difference in the volume of water in the CCS between the final and first days of the calibration period, divided by the number of days in the period, was observed to be 0.54 mgd. Though the model underestimated a net outflow of water from the CCS over the whole time period, the residual error between the simulated and observed flow is very small (0.32 mgd). This error is small (0.3%) relative to the monthly net observed flows, which range from a net outflow of 46.6 mgd (October 2010) and a net inflow of 52.1 mgd (September 2010).

The model simulated a net influx of salt over the 57-month period at rate of 597 (lb x 1,000)/day.

The corresponding observed rate of salt inflow was calculated by multiplying the average observed salinity in the CCS on the final and first day of the calibration period by the corresponding CCS volumes on those days. The difference between these two products, divided by the number of days in the calibration period, shows that the net inflow of salt is about 405 (lb x 1,000)/day. The error associated with the mass flux is an overestimation by approximately 192 (lb x 1,000)/day. As in the case of water balance simulation, the magnitude of this overestimation is small (0.9%) relative to the range in monthly average flows; the monthly net mass fluxes range from an outflow of 13,790 (lb x 1,000)/day (October 2010) to an inflow of 8,659 (lb x 1,000)/day (June 2011). This error marks an improvement over an earlier version of the model (discussed in the 2014 Annual Post-Uprate Monitoring Report [FPL 2014a]).

Figures 5.3-2 and 5.3-3 illustrate the models ability to match the magnitude and direction of net monthly flows of water and salt, respectively. Figure 5.3-2 compares observed and modeled net monthly flows of water into and out of the CCS. There is a seasonal trend in observed flows to/from the CCS, where inflows are generally associated with the wet season and outflows are generally associated with the dry season. The model is able to replicate this trend reasonably well. However, there are isolated periods of time where the model does not accurately simulate the magnitude or direction of the net flow (e.g., March to July 2011, October 2013, January 2015). Figure 5.3-3 compares observed and modeled net monthly flows of salt into and out of the CCS. Like the modeled water flows, estimated salt mass fluxes generally match observed fluxes well, although there are individual months where the estimated mass flux is less accurate.

5-8

FPL Turkey Point Comprehensive Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - March 2016 Section 5 Implicit in the models ability to simulate monthly net water and salt mass flows is the accurate simulation of daily flows to and from the CCS. Because the model is able to characterize the daily flows of water and salt, the model is able to estimate the daily changes in CCS water and salt storage. As previously mentioned, these changes in storage are associated with daily changes in CCS water levels and salinity. Figure 5.3-4 shows the model-calculated water level in the CCS, which varies over the period of record. These modeled water levels range between approximately -1.63 ft NAVD 88 and 0.81 ft NAVD 88 and reflect an average water level throughout the entire CCS. The observed CCS water levels over time are also shown in this figure; the observed values reflect the mean of daily-averaged water elevations across the seven sensors in the CCS. The daily-averaged observed water levels vary across a range similar to that of the simulated water levels (-1.71 ft NAVD 88 to 0.63 ft NAVD 88). Simulated water elevations are calculated by dividing the simulated daily change in CCS storage by the average daily CCS surface area and adding the resulting value (which reflects a change in water level) to the previous days simulated water elevation. It is evident from this figure that the model effectively captures the general trend in CCS water elevations over the 57-month period and accurately simulates average CCS water elevations throughout much of the calibration period.

Nevertheless, there were periods of time where the model either generally under-simulated observed water levels (late 2011 and 2013) or, conversely, over-simulated water levels (mid-2014 through May 2015).

Though the model over-simulated water levels toward the end of the model simulation, this error is relatively small. Moreover, the temporal fluctuations in water levels are reasonably well-matched. This is particularly relevant since this period of time includes fall 2014, when 914 million gallons of L-31E Canal water were pumped into the CCS over a 21-day duration. During this addition, the simulated increase in water levels (approximately 0.5 ft) closely matched the observed water level increase in the CCS (approximately 0.4 ft). The model also accounted for water pumped into the CCS from the Floridan Aquifer (PTF5 well #3) and Biscayne Aquifer (PW-1) and the associated changes in stage since July 2013 and January 2015, respectively.

Similar to the calculation of CCS water levels, changes in salt mass storage within the CCS can be used to calculate average CCS salinity changes over time. The simulated daily net flow of salt is divided by the simulated volume of water in the CCS, which results in a change in salinity.

This change in salinity is added to the simulated salinity calculated for the previous day to produce a simulated salinity for the current day. Like the simulated CCS water level, the model salinity reflects a representative daily salinity throughout the CCS. Figure 5.3-5 compares the simulated salinities to those observed in the CCS over the period of record. Observed salinities are the mean of daily averaged salinities measured in the CCS monitoring stations. The model under-simulated salinity between May 2012 and December 2013 and over-simulated between June 2014 and May 2015. However, these under- and over-simulations were generally small.

Moreover, the simulated temporal trends in salinity throughout much of the 57-month timeframe matched the temporal trends in the average observed CCS salinity.

As in the case of the simulation of water levels in the CCS, it is important to note that the model simulated salinity and daily changes during the November 2013 through September 2014 timeframe, when salinity increased from about 60 g/L to approximately 90 g/L. Moreover, the 5-9

FPL Turkey Point Comprehensive Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - March 2016 Section 5 modeled drop in salinity (11 g/L) due to the addition of L-31E Canal water from September to October 2014 closely matched the observed drop in salinity (13 g/L). In addition, the subsequent increase in salinity (October 2014 through April 2015) was replicated by the model, as was the subsequent significant drop in salinity attributable to a late-April rainfall event. The fact that the model matches these notable fluctuations in CCS salinity reinforces the conceptual model, which suggests that changes in CCS salinity are predicated solely on changes in the flow of water into and out of the CCS. Again, changes attributable to the addition of Floridan Aquifer water from PTF5 #3 and Biscayne Aquifer water from PW-1 are accounted for by the model with reasonable accuracy.

Given that the simulated timeframe is nearly evenly partitioned into the Pre-Uprate, Interim, and Post-Uprate periods, it is appropriate to discuss the water and salt balance model results in terms of these operational periods. Inspection of Figure 5.3-2 does not reveal a marked difference in water changes in water storage (inflows and outflows) among the three operating periods.

Perhaps the only distinguishing characteristic is a significant decrease in storage (outflow) that occurs at the inception of the Post-Uprate period in June 2013. This outflow is attributable to increase in seepage to groundwater and in evaporative losses. Figure 5.3-3, however, suggests that mass accrues at a greater rate during the Post-Uprate period than in the other two operating periods. This is consistent with the increase in CCS salinity during this timeframe.

Tables 5.3-6 and 5.3-7 summarize the simulated water and salt flow balances for the Pre-Uprate, Interim, and Post-Uprate periods. Though the net water and salt balances are on the same order of magnitude for each of the three operating periods, the magnitude of the inflows and outflows are fairly different. For instance, the magnitude of water inflows and outflows are greater during the Pre-Uprate and Post-Uprate periods than in the Interim period. Likewise, the exchanges of salt are generally greater in the Pre-Uprate and Post-Uprate periods than in the Interim period.

The modeled water balances match the corresponding observed balances reasonably well in each of the operating periods. Though the match between modeled and observed salt mass balances appears to be slightly degraded when compared to the water balance match, in fact the associated salt mass balance error is relatively low in the context of the range of the individual mass balance components (e.g. maximum inflow minus maximum outflow). Additionally, relative to the variability in observed monthly net salt mass flows, the error between the simulated and observed mass balance for these three periods is fairly low The accurate simulation of changing CCS inflows, outflows, water elevations, and salinities is complex due to the different components of the balance model and their varying impacts upon CCS water and salt storage. For instance, vertical flows into and out of the control volume are generally larger than horizontal flows and have a greater impact on CCS water elevation. The salinity of inflowing water, however, can vary depending upon the source of the water. For example, horizontal flow from the west (L-31E Canal) is non-saline and has a pronounced mitigating impact upon CCS salinities; vertical flow from groundwater beneath portions of the plant discharge canals is saline to hyper-saline and generally increases the salinity of the CCS.

The correct balance of both water and salt mass flow is difficult to estimate in the model. In addition, the simulated timeframe encompasses Pre-Uprate, Interim, and Post-Uprate periods, during which CCS water salinity and temperatures fluctuate significantly. The model addresses 5-10

FPL Turkey Point Comprehensive Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - March 2016 Section 5 associated impacts on the CCS by explicitly simulating the effects of water/air temperature gradients on evaporation. Whereas numerous sources and sinks of water, varying salinities, and changes in water temperature do increase model complexity, the need to accurately simulate these different components of CCS operation constrains the number of possible solutions.

Though the model is able to simulate the complex dynamics associated with the CCS over a 57-month timeframe with reasonable accuracy, there are periods of time where the simulated flows of water and salt do not accurately reflect observed conditions. Consequently, the simulated water level and salinities in the CCS deviate from those that have been observed at various times in the simulation period. However, the overall performance of the model reinforces its utility as a tool for understanding how the CCS has and will operate under varying meteorological, hydrological, and operational conditions. This is best demonstrated by the fact that the same conceptual model employed to characterize changes in CCS storage of water and salt during the Pre-Uprate period is used to explain changes in water and salt storage during the Post-Uprate period, a period of time during which water levels have generally decreased, salinities have dramatically increased, water temperatures have risen, and algal blooms have developed within the CCS. Nevertheless, the exchanges of flows between the CCS and surrounding environment during Post-Uprate period are governed by the same hydrologic principles as during the Pre-Uprate period.

This robustness and accuracy in the model underpins FPLs understanding of processes that control the CCS and the manner in which the CCS interacts with the adjacent aquifer and water bodies. This accuracy in simulating the historical changes within the CCS bolsters confidence in the models utility as a tool to evaluate the sensitivity of CCS operations to certain factors, such as changes in operation, drought conditions, storm events, added water, and other potential environmental stresses. Additionally, the model accuracy validates the fact that the most appropriate data are being collected to effectively capture CCS operations, identify interactions between the CCS and the surrounding environment, and support FPLs comprehension of historical and future operations of the CCS. This model continues to be refined and improved with further information on the CCS.
