Summary

The evaluation uses a control volume/energy balance approach based on the first law ofthermodynamics or conservation of energy to determine the daily temperatures of the lowerLake Granbury volume (upstream of DeCordova Dam). The methodology uses the highestdifferential temperature between the discharge and the background temperatures, historicallyoccurring: during the winter months, and a period of low flows through the lower lake volume.Historical data with a reasonable number of recorded river temperatures (river temperatureswere not recorded on regular bases) and times where low flow rates through the, lower' lakevolume were searched. A 65-day period between December 11, 2001: and February 13, 2002was selected for evaluation along with assumed preliminary design information forthe proposedComanche Peak Nuclear Power Plant (CPNPP) Units 3 and 4. The nettemperature increase forthe 65-day period is conservatively evaluated to be <1.00°F, which would be mitigated by thelake's surface evaporation.

Purpose

The purpose of this evaluation is to enhance the information supplied in the CORMIX runs forthe iowerLake Granbury area and to verify results would meet the predicted permitrequirements. CORMIX inputs a single flow regime for the river or lake that provides a plume forthe thermal or toxin input. Low lake or river flow conditions reliably provide the largestconservative thermal plumes that will meet permitted or proposed permitted conditions ascalculated by CORMIX; however, CORMIX provides no information on possible accumulationsof heat. This energy balance provides a conservative estimate of heat accumulation in the areabetween the cooling tower blowdown discharge and the lake intakes.

Results

The cooling tower blowdown discharge into Lake Granbury will create a plume that is warmerthan the surrounding environment and will, therefore, be more buoyant. The plume will spreadacross the, surface of the control volumewith enough. energy to iniduce additional evaporation.This evaporation provides the largest heat transfer from the control volume and is modeled as a

cooling pond for this report. The heattransfer, along with normal mixing limits, will heat the arealess than 1IF and agrees with the CORMIX findings. In addition, the normal evaporation thatequates to more than 1.7 billion btu/day (Reference 12) removed from the lake surface will morethan mitigate the heat buildup determined by this evaluation. Therefore, the discharges from theplant into Lake Granbury should meet the predicted permit requirement of less than 3°F heatbuildup.

td is the discharge temperature based on bin data from the URS optimization study (Reference1). Average daily wet bulb temperatures as determined from Reference 4 are used 'inassociation with bin data from the URS optimization study (Reference 1) for the selectionof daily intake and discharge flows, along with the discharge temperature.

Additional evaporation .(md*Cp*Athl) used-to determine the evaporation losses from the volumeis found using cooling pond 'information from Perry's Chemical Engineers' Handbook(Reference 5). The area of the cooling pond used for cooling the maximum dischargetemperature down to an acceptable temperature is found using' the nomograph(Attachment A) from Reference 5 and is found to have an approximate size of 118.83acres. The cooling pond size in Ref. 5 is smaller than the area being evaluated (281.60acres in Reference 10) and is considered conservative for this study. The temperature(thl) used is the difference in the discharge temperature and the daily volumetrictemperature, minus the cooling pond approach of 3'F from Reference 5. The md value isnot the mass evaporated, but is used to determine the heat used for evaporation inaccordance with Reference' .5 guidance.

Assumptions

1. Additional evaporation is estimated: in accordance with cooling pond information frpmPerry's Chemical Engineers' Handbook (Reference 5),and& included in Attachment'AA.

2. Surface or natural evaporation and solar loading were .neglected within the formalevaluation, but provide .basis forthe assumption that zero energy would be transferredacross the control surface.

3. Units 3 and 4' discharge temperatures and-flows are based on daily average wet bulbtemperatures in Ref. 4 and correlate with values from Reference 1.

4. Units 3 and 4'intake flows are based on daily average wet bulb temperatuhres, inReference 4. and correlate with values from Reference; 1..

5. Daily lake temperatures were not available; therefore, the baseline lake temperature isthe:average of the four lake temperatures for the 65-daylrun.

6. The highest differential lake temperatures as compared to thecooling'tower dischargeare assumed to occur during the winter months'.

7. Actual permit. conditions were not available;' therefore, information from the TexasA'dministrative..Code is used. The permit Condition for temperature change.is assumed-tobe less than 30F for the plant discharge (Reference 7).

8. Conservatively assumed winds are 2 mph for the. Lake 'Granbury area. Using Table2.7"45 of Reference 11., wind speeds for the area near c PNPP are less than. 7.5 mph,verifying the conservatism of this assumption.

9. No rain or snow is assumed. for this, evaluation period-10.. All worksuch as. boating, actions-of wildlife, etc. are considered negligible.11. There is no mass gained or lost froni the control volume during'this evaluation. Actually

mass is lost due to evaporation in the-area, but is considered negligible due to thecooling that would' occur with this phenomenon.

12.. The cooling pond approach of 30F is Used because the discharge pond depth' isgreaterthan .5 feet.

13.. Heat transfer between earth and pond, changing temperature and hu midity .pf the air asit transverses the water, and rain have minor effects, on heat transfer for cooling ponds:(Reference'5), and therefore are assume'd negligible forthis evaluation.*

14. The variation temperature as defihed in Reference 5 of plus or minus 30F is assumed tobe.OOF for this report, and considered to be Conservative because of the large -surfacearea being evaluated.

W is the rate of energy transfer by work across a boundary in watts. Work is, negligible andconsidered zero for this evaluation.

The velocity (V) across the control surface does not changeand is therefore neglected.

z is elevation in feet. There is no elevation (z). change across the control surface and is z.therefore zero.

h is: specific enthalpy in btu/lb.

mri is the mass flow across the control surface due to additional intake flow in-Ibm/day.

md is the mass flow from Units 3 and 4 in Ibm/day.

Tj is the initial temperature in 'F.

Td is the discharge temperature in 'F.

Cp is specific heat of water,, which is equal to approximately 1 btu/Ibm°F.

The exit energy equation is broken down as follows:

mrh Cp T = ihi Cp T, + mr Cp T, + md Cp AT 0ex

Where:

mi is the mass intake flow in Ibm/day.

mr is the through control volume flowt(same as in the inlet energy equation above).

md is the mass discharge flow as used per Reference 5 to determine evaporation in Ibm/day.

T, is the temperature of the control volume that is changing on a daily basis in -°F.

ATe is the difference between the discharge temperature and Tv, minus the approachtemperature of 3F.

Revised Elevntion.4rca-Volurne Estimates for Lake Granbun,,: Hood County, Texas

Stephen K. Boss, Ph.D., P.C.Department of GCeosciencesUniversity of ArkansasFayettevile, AR

SUMMARY":

Mr. DarTen Lovvom requested revised estimates for elevation-aren-volume relations for amodified region of Lake Grabnbur. corresponding to a pool elevation of 691 fl.on 8 May 2009(Fig. 1). Theic modified area is reduced somewhat from the original mapped area of LakeGranbury. 'the normal conservation pool of Lake Granhurv is 693 ft a~d-lihe original studiedarea was 577 acres. "llie modified area that is subject.of this brief amalysis is3 1 0-acres (53.7%.ofthe original.area) and 2 feel below the normal conservation pool.

The are~a for which calculations hav\e been completed includes the main body of the reservoirlessthe area ol'the prdminent ahn imniediately northwest or D)e Cordova liend l)Dm. Bathymetriedata were not available for the prominent lake ann immediately northwest of the De CordovaBend Dam. 'T'his arm is approximately 30 acres and presumed to be relatively shallow (<6 11).As such. it very likely represents a relaitvely small volume ofthe studied area (less than 180 acreIcet at 691 Rt. elevation). Note that no data for this ann were reported on prior reports. so resultsreported here will be compamrable to prioi reporis.

'The area l'ur wvljiit result', me reported here haes a uttitsured surfaee ar'eii of 281.6 acrrs. '1he

estitiialed voltime storage of this a.rea at 691 fl. elevation is 9,.668 acre-feet, This volumne is ca.62% of the volum elstimated for the original study area. Again, the proimtin3t lake arm NW ofLhe darn site may contribute an additional 100-200 acre-feet to this toalaif included. *fhougli thearea that is subject of this analysis is only slightly more than 501% of the original area, it contains62% of the storage volume owing to the fact that it includes the deepest. portions of tle reservoiralong an incised portion of the forner course of the Brazos River.

Figure 2 of this report illustrates area versus elevation•relations for this portion of the reservoir.The overall tonn of this Curve is comparable to that inthe original report for the larger mappedarea. Thie piromineiit ciangcs -in slope of tlhe curve apparently refleet the presence of now-s1bmerged stream terraces of the Brazos River..

Figure 3 illustrates area versus volumne relations within this portioeof the reservoir. Note that.area becomes constant as the reservoir is bound along its margins by outcrops with nearlyvertical walls. 'ltus, reservoir area does not increase as volume increases due to rising lakelevel.

Figure 4 shows the relation of reservoir volume to elevation. This curve is quite typical ofriverimpourndments. and is comparable to that front the original report for this reservoir.
