Revision 6 l l Standby Nuclear Service Water Pond - Thermal Analysis During One Unit LOCA and One Unit Shutdown. (TotalRewrite) , I l STATEMENT OF PROBLEM l The Standby Nuclear Service Water System at Catawba Nuclear Station is designed to provide emergency cooling water during a one-unit Loss of Coolant Accident (LOCA) plus a one-unit cooldown. This water is supplied by the Standby Nuclear Service Water
]
Pond-(SNSWP). The SNSWP was formed by impounding a cove of Lake Wylie, immediately north of the plant area. During normal operation, Lake Wylie is the source of nuclear service water and also dissipates the waste heat from the discharge. l I This calculation determines the plant intake temperature from the SNSWP during the cooldown procedure. The nuclear service water system is designed to operate properly I within a specific temperature range. This calculation verifies that the SNSWP intake ' water is within that range, and that there is a sufficient quantity of water to supply the plant for 30 days. ! l 1 1 0 5 L
CNC-1150.01-00-0001 Originated by: R. E. Baker Checked by: T. K. Ziegler Date:- 5/25/95, Page 2 of 59 Revision 6 , PURPOSE OF REVISION t The purpose of this revision (6) is to examine the effect of a proposed change to the Catawba Technical Specifications on the SNSWP temperature limit. This ch'ange includes: Changing the Technical Specification SNSWP elevation limit from 570 ft msl to 571 ft msl. (As a result, the pond thermal analysis was run with area-volume values to reflect the more stringent elevation requirement.) Additionally, this revision includes the effects of changes to the area-volume cmve, heat loads, flowrates, and worst-case meteorology. QA CONDITION These calculations are QA condition 1 because the RN System is designed to operate properly with a specific temperature range.

Ziegler Date: 5/25/95, Page 3 of 59 Revision 6 DESIGN METHOD Analvtical Model Descriotion An in-house analytical model was used to determine the warmest plant intake temperature from the Catawba SNSWP during the 30-day cooldown following a one-unit LOCA. The model treats the Catawba SNSWP as a series of stacked horizontal layers of water. Operation of the pond is simulated by removing the bottom slice, adding heat to it and then placing it on top of the stack where it is permitted to cool. Cooling takes place only in the surface layer and at a rate proportional to the water temperature excess above the equilibrium temperature. The heat transfer is simulated by the following equation from Edinger and Geyer (1965): dT K(T- E) T p CJ where: T= water temperature K = heat exchange coefficient E = equilibrium temperature p = water density C = specific heat d = depth of the upper slice of water i = length of time cooling takes place 4 I e Y l

; system leakage losses which result at the end of the 6th day of an initial model run at the start of the simulation. This initial mn (see Attachment A, Model Run with Initial
' Elevation of 571 ft msl) used a starting elevation of 571 ft mst (proposed Technical SpeciScation limit) along with the updated input values described previously in this
- section. This is a conservative approach because the peak temperature occurs on the 5th day of the simulation. The losses at the end of the 6th day are as follows:
- Evaporation losses of 11.7'ac-ft (see value in Attachment A model run, page A10)
- Seepage losses of 0.36 ac-ft (see Attachment A)
- System losses of 1.31 ac-fi (from ioss values of 225,000 gallons for first 5 hours and an additional loss of 1.01 E6 gallons total loss occurring over the 30-day period at a steady rate (see Attachment B)
. Total of 6-day losses = 13.37 ac-ft (Use value of13.5)-
Using the total volume (447.5 ac-ft) from the starting elevation of the initial mn presented in Attachment A, the initial cooling volume can be determined (447.5 - 13.5 = 434 ac-ft). From linear interpolation, (see Attachment A) the associated surface area is 37.9 acres with an elevation of 570.64 ft msl. Thus, the first two volume values in the data input file are 434 and 396.1 ac-ft, respectively. t 0 8 a h [ 4 (

Ziegler i I Date: 5/25/95, Page 10 of 59 Revision 6 Initial Pond Temperature (Isothermal) The SNSWP temperature values do not inr'.ude the 2.13 F instmment inaccuracy correction for the permanent temperature mcritoring system. The limiting value of SNSWP temperature which allows compliance with the nuclear service water intake temperature requirements of the Catawba FSAR was determined by
. varying the initial temperature for different model mns (30-day simulations). The FSAR requirements are:
e no increase in intake temperature above 92 F over the first 12.5 hours following a one-unit LOCA, and e l no intake temperature over 97.6 F during the 30-day one-unit cooldown period following a one-unit LOCA. Stratification conditions often exist in the SNSWP during the critical summer months I
- (June, July, August). However, the temperature inputs in these model runs (see Figures 6 j and 7) conservatively assume isothermal conditions in the SNSWP at the start of the j simulation.

Demands on SNSWP" are used in the simulations (see table in Attachment B). l 4 The computer program (see Figures 1 and 2) reads 52 heat load values directly from the
' input data sets (see Figures 6 and 7). These values are assigned as follows:
l l . Hours 1 - 29 One value is read for each hour .

- Hours 30 - 190 One value is read for each 10-h'our period. This value is
- then assigned to each of the 10 hours in the period.
f . Hours 200 - 720 One value is read for each 100-hour period. This value is then assigned to each of the 100 hours in the period. Worst-Case Meteorology The meteorological inputs to the Catawba SNSWP computer model consist of dry bulb temperature, dew point temperature, wind speed, heat transfer coefficient (computed) and the equilibrium temperature (computed). As suggested in Regulatory Guide 1.27, Revision 2, the worst-case meteorology was determined based on the critical (5-day) cooling period (see description of review process in Attachment C). . As a result of the meteorological review, the 30-day period from 6/23/52 - 7/22/52 (with 6/23/52 - 6/27/52 being the worst 5-day period) is used as an input to the model (see Figure C2). I l e

Ziegler Date: 5/25/95,Page 12 of 59 Revision 6 WATER SUPPLY The full pond elevation for the SNSWP is 572 feet msl and the minimum level for the pond is 571 feet msl. The water supply in the SNSWP may be decreased due to: ) e evaporation . seepage e system losses. The drainage basin for the SNSWP has an area of approximately 410 acres. Run-off and groundwater flow from the basin are the sources of water for the pond. A typical drainage basin yield for this area is 1 cfs/mi,2 which for the SNSWP basin equates to 0.6 cfs. Average lake evaporation for this area is about 41 inches / year, which for a pond area of j 40.6 acres (Area at elevation 572 ms!), is about 0.2 cfs. If needed, makeup water to the 1 pond can be provided by aligning the nuclear service water discharge to the SNSWP, l During a 30-day LOCA period, there would be increased water loss from the pond by forced evaporation due to elevated surface temperatures. Evaporation is calculated for each iteration time step of the computer simulation. The cumulative evaporation through , that time step is then printed. Seepage from the SNSWP is analyzed in CNC-Il50.01-00-0004, " Standby Nuclear Service Water Pond- Seepage Loss Analysis"(see Attachment A). The worst-case loss at the end of six days is 15,547 ff. An additional 10.75 ff/ day is lost through seepage through the SNSWP dam embankment. A 6-day seepage total of 15,612 ff (0.36 ac-ft) results from these values. l 1 t-

Ziegler Date: 5/25/95, Page 14 of 59 Revision 6 SNSWP HYDRAULICS The Catawba SNSWP is designed to prevent short circuiting of the heated water, and to effectively utilize the full pond surface for cooling. The plant intake is located at the bottom of the pond and the discharge at the surface The nacked layer concept assumes warm water surface layers cannot be pulled into the intake. Harleman and Elder (1965) analyzed the potential for pulling an upper, warm buoyant layer of water down into a submerged intake (see Attachment D). If a computed withdrawal depth (H) is less than the depth from the warm water interface to the intake (D), then less than 5% of the intake will be pulled down from the surface layer.

Thus, significant recirculation of the heated surface layer will not occur until the depth of the heated layer exceeds 18.5 feet. Therefore, a stacked layer model analysis is appropriate for the simulation. 4 0 e h*

The densimetric Froude number F(calculated using the following equation), which represents i the ratio ofinenial forces to buoyant forces, is used to determine the extent of mixing in ! the SNSWP.

CNC-1150.01-00-0001 Originatedby: R.E. Baker Char *arl by: T. K. Ziegler Date: 5/25/95,Page 17 of 59 Revision 6 Assuming a 15 degree (from the venical) discharge angle, a plume 65 ft wide and 4 ft deep results 100 ft downstream from the discharge structure. At these conditions, and assuming the previously discussed temperature difference of 8'F between layers, the densimetric Froude number is 0.66 for the high flow conditions during the first 4 hours of the simulation. A conservative estimate of 75% of the flow (102.5 cfs) going out the short-arm discharge is made in this calculation (see Attachment E for additional information). Thus, mixing will be minimized except in the immediate vicinity of the discharge structures and pond stratification will be preserved. The Catawba SNSWP is a stratified pond, and as mentioned previously, has a bottom intake, surface discharge configuration with minimal discharge mixing. Ryan and Harleman (1973) have shown a pond designed in this manner will effectively utilize the total pond surface area in dissipating heat to the atmosphere regardless of pond shape. Physical testing performed during February '1994 verified strattfication conditions exist in ] the SNSWP with an associated complete surface spread of the heated layer. l
-In- summary, model assumptions of no direct recirculation of the heated plume and .
l utilization of the total lake surface area and volume are valid for the Catawba SNSWP l application and have been supponed by physical testing and theoretical analysis. o 0

- The 22.8 MG (70 ac-ft) circulated during the first 12.5 hours of the simulation will displace (approximately) the top 2 ft (571 to 569 ft ms!) of the SNSWP.
The significant difference in elevation between the lower depth of the heated layer (569 ft .j msl) and the availability of water at 92 F at all elevations below 557 ft mst ensures that no water in excess of 92 F will be withdrawn during the first 12.5 hours following a one-unit LOCA. Additionally, the probe elevation of 568 ft MSL is high enough to ensure an adequate supply of" cool" water (< 92*F) fduring the first 12.5 hours of the accident .. e t i
CNC-1150.01-00-0001 Originated by: R. E. Baker Checked by: T. K. Ziegler Date: 5/25/95, Page 20 of 59 Revision 6 RESULTS The effect of the proposed change to the Catawba Technical Speci6 cations (SNSWP l elevation limit increase from 570 ft mst to 571 ft ms!) was examined with a set of computer simulations. The pond thermal analysis was run with area-volume values (corrected for cumulative inventory losses occurring at the simulated peak temperature) to reflect the more stringent elevation requirement. Additionally, the runs include the effects of recent changes to the area-volume curve, heat loads, flowrates, and assumed worst-case meteorology. i Maximum pond intake temperatures resulted (shown in the following table) from the ; computer simulations. See Figures 6 and 7 for the inputs and results of the computer simulations. Flowrate Set Initial SNSWP Maximum SNSWP Intake Temperature ("F.) Temperature ( F) Low (38,000 gpm for hours 0-4 and 19,000 91.5 96.87 gpm for hours 5-720) High (46,000 gpm for hours 0-4 and 23,000 91.5 97.52 gpm for hours 5-720) The high flow case results in a temperature maximum of 97.52*F at 10 '.6 hours (5th day) while the low flow case results in a temperature maximum of 96.87'F at 130.3 hours (6th day). Both cases (high and low flow) maintain temperatures of 91.5*r at the SNSWP for the first 12.5 hours of the simulation.

l CNC-1150.01-00-0001 Originated by: R. E. Baker Checked by: T. K. Ziegler Date: 5/25/95,Page 21 of 59 Revision 6 CONCLUSION This calculation simulates operation of the Catawba SNSWP during a one-unit LOCA and subsequent 30-day one-unit cooldown with extreme meteorology and conservative ; I assumptions regarding SNSWP heat content when the LOCA occurs. Based on this 1 computer analysis, the maximum SNSWP intake temperatures were ' determined to be l below 97.6'F for an initial SNSWP temperature of 91.5'F. Additionally, there are no ! SNSWP intake temperatures greater than 91.5 F during the first 12.5 hours of the simulated accidents. The pond analysis was conducted utilizing updated values for: . Area-Volume Curve Values . Heat Loads . Flowrates . Worst-Case Meteorology. An initial SNSWP temperature of 91.5 F results in a peak of 97.52 F on days 5 and 6 of 1 the high flow simulation. Therefore, the SNSWP is operable for initial SNSWP temperatures up to 91.5 F with a SNSWP elevation of 571 ft msl. l e

SI: S1 is the depth in feet available for use in the SNSWP. The full pond elevation of the SNSWP is 572 feet mean sea level (ms!). The pond elevation is set at 570.64 ft mst for the LOCA analysis due to losses (see Model Inputs section). The intake for the nuclear service water system is at elevation 540 feet mst (see Figure 6). This gives a total usable depth of greater than 30 feet for the SNSWP. Tl: Tl is the number of hours of input and analysis for the LOCA period. From Regulatory Guide 1.27, Revision 2,720 hours (30 days) is used. LI: L1 is the number of unit volume layers. From engineering judgment, 20 unit volume layers are used. The number oflayers selected has only a very slight impact on the calculated temperatures, ~unless a very small number is used, which will have a i much greater impact, l K2: K2 is the output check spacing. The number used does not influence the model results at all. K2 is assumed equal to 20. S(I,1): S(I,1) is the volume of the pond at each foot of elevation. The numbers are from the area volume curve (see Attachment A). S(I,2): S(I,2) is the initial temperature of pond in degrees F. T(1,3): T(1,3) is the flow rate from the SNSWP to the plant for hours 1 through 4 and hours 5 through 720 (See Input Section, Reference CNC-1223.24-0041).

AQ) A(J) is the daily air temperature, 'F, for the 30-day LOCA period. E(D: P(J) is the daily dew point temperature, F, for the 30-day LOCA period. W(Jh W(J) is the daily wind speed measured at 2m height, mph, for the 30-day LOCA period. FA E(J) is the daily equilibrium temperature, 'F, for the 30-day LOCA period.

,, Two cases should be considered in the SNSWP thermal analysis. The "High Flow" case should consider the flow to be 46,000 gpm for the first four hours of the event and 23.000 gpm thereafter. De " Low Flow" case should consider the flow to be 38,000 gpm for the first four hours of the event and 19.000 gpm thereafter. By evaluating the highest and lowest expected Design Basis Event tiowrates, it is assumed that the analysis is valid for the full range of flowrates. System. and therefore SNSWP. inventory losses total 1.24 E6 gallons. CA makeup accounts for 0.225 E6 gallons over the first 5 hours of the event. The remaining 1.01 E6 gallons is due to ruel pool boil off at a constant rate of 23.4 gpm over the 30 day event.

Attachment C. - Worst Case Meteorology The meteorological inputs to the Catawba SNSWP computer model consist of dry bulb temperature, dew point temperature, wind speed, heat transfer coefficient (computed) and the equilibrium temperature-(computed). As suggested. in~' Regulatory Guide 1.27, Revision 2, meteorology for the worst cooling period is used. The regulatory guide states in part,'"The meteorological conditions considered in the design of the sink should be selected with respect to the controlling parameters and critical time periods unique to the specific design of the sink" Forty-four years (January 1949 - December 1993) of daily average meteorological data ' from Charlotte, North Carolina Airport were scanned by computer. (using-'Microsoft Excel) to identify'the design' basis periods. Meteorological data from Charlotte is considered representative of the Catawba site because it is located only 13 miles east of , the site. The weather programs (which will be) described in COM-0203.C6-17-0147, "NWSMET: Surface Meteoroingical Observations and Hydrothermal Program" were used to generate the computed meteorological data (heat transfer coefficient _and equilibrium temperature). The " worst heat transfer" condition is defined as the period in which the equilibrium temperature is the highest. Equilibrium temperature is defined as the water surface temperature at which heat flux into the surface would equal heat flux out.' Therefore, the historical period with the highest equilibrium temperature will define the period in which the least amount of heat will be lost from a thermal discharge'and in which critical return temperature from the SNSWP would occur. The Ryan Heated equilibrium temperature (T.) weather data generated for_ the years 1949-1993 was loaded into an Excel . spreadsheet. The rolling 30,6,5,4,3, and 2-day averages (as well as the 1 day values) of. the Ryan Heated T., values were reviewed and the data with the' highest equilibrium temperatures were extracted. The resulting data is shown in Table C1. The table shows the extracted data meeting the conditions of greatest values for each of the average lengths.

Guide 1.27. The " critical time period unique to the specific design of the sink" is 5 days because the SNSWP intake temperature reaches its peak on the 5th day of the simulation. The maximum 5-day average period begins on 6/23/52. This 30-day period is used because of the 5-day peak timing. Although the 30-day period beginning 6/23/52 is not the worst 30-day time period (which begins 6/30/93), this 30-day period ; (6/23/52) does represent the most conservative meterological data during the critical time period for the specific design (including the heat rejection and flow rate characteristics) of l the Catawba SNSWP. The data for the 30-day simulation period is shown in Table C2 "30-Day Worst Case Meteorolo! , C2

HYDRAULICS DIVISION Proceedings of the American Society of Civil Engineers 4 WITHDRAWAL FROM TWO-LAYER STRATIFIED FIDWS l By Donald R. F. Harleman,1 M. ASCE, and Rex A. Elder,2 F. ASCE i 1 INTRODUCTION 4 During the past decade, the Tennessee Valley Authority (TVA) has built ' several intake structures designed to withdraw cold water from the lower ; i levels of thermally stratified rivers and reservoirs. The cold water is used to supply condenser wsiter for industrial cool'ing water systems. During the j summer months, the primary flows in the Tennessee Valley system are con- - trolled by releases from upstream storage dams through low level turbine . intakes. Under certain conditions, the cold water discharged by the turbines . may form a gravity underflow in the downstream rivers and reservoirs that -- may be from 10' to 1S' F. colder than the overlying surf ac e water.3,4,5 Withdrawal of the colder bottom waters from such stratified conditions re-quires special intake structures that prevent the warmer top water from being pulled into the pumps. Inthe absence of the stratification caused by reservoir releases,a thermal stratification will generally be developed in the vicinity of a steam power plant by the heat input caused by the return of the hot condenser water to the river. Part of the heated water flows upstream by virtue of its lesser density Note.-Discussion open until December 1,1965.To extendthe closingdate one month, a written request must be filed with the Executive Secretary.

INTRODUCTION Flood plain regulation has been called a *New Approach to Local Flood problems."3 In recent years many engineershavebegunto realize that struc-tural flood control measures are not the only answe of the flood plain through flood plain regulations is becoming ra.:ognized as an important environmental control measure but deserves even more atten-g tion by all concerned including engineers, planners, governmental agencies.
2 and affected individuals. Floods affect man's environment significantly: Rey health; they threaten his property-his home his business, or his place of
,g employment. Neither flood plain regulations nor other flood damage preven-tion measures are likely to eliminate these threats completely because man is powerfully attracted to use of the flood plain. Ilowever, they certainly can reduce them and they should be given increasing considera the flood plain. These include acquisition of flood plain
- by public agencies for uses that will serve the public need and which will not suffer or cause I increased damages. Recreation areas are a prime example. *Open spaces f
- are becoming more appreciated as they become more scarce. Use of the flood plain for public parking is generally acceptable.
Tax policies, loan and finance practices flood hazard information dis-semination, warning signs. and other measures can also be used to help man use the flood plain wisely and safely.
