o L I. Introduction 7 The. spray ponds of the Rancho Seco Unit 'l Nuclear Generating Station are s-two redundant systems designed to dissipate nuclear. decay heat and auxiliary equipment waste heat during ~ periods of shutdown for maintenance and in emergen-cies including the design basis accident, the loss-of-coolant accident (LOCA). Each pond must-have the thermal capacity to dissipate the thermal load associ-ated with the:LOCA under conservative meteorological conditions and limit the cooling water temperatures. to the design ranges of system components. Addition-ally the pond water inventory must be capable of sustaining this performance w. . for a period of 30 days following the hypothetical LOCA. i. Because the detailed performance parameters of spray ponds are not well s, established the Atomic Energy Commission has asked that Sacramento Municipal i F Utility District (SMUD) provide additional evidence of the ability of the ponds I to meet the design criteria. To obtain the necessary supporting information t-SMUD has asked the University of California, Berkeley, to carry out an experimental l-(, evaluation of the performance of the ponds. Of.particular concern is the efficiency of the spray nozzles and its depen-dence up,on operating variables and the drift loss dependence upon wind speed and heat load. These performance factors are central to the calculation of com-i.. pc >ite behavior of the system mentioned in the first paragraph. } The University of California study is in two parts. Phase I consists of the equipment test program and the basic results contained in this report which a i are needed to demonstrate adequacy of the system design in response to the AEC j request. Phase II will consist of a more detailed analytical study and laboratory U,

experimentation' on individual nozzles.

Phase II is not necessary to demonstrate Q system adequacy but is ' conducted to advance the state of the art and to provide the' industry _with detailed information to be used in' the design of future systems. Phase II-report will be available upon request to the District. These studies. Q] will be~ aimed at developing more accurate methods for design of spray ponds and k c n k'l

prediction of the parameters on which these designs depend. .4* II.. Objective The objective of the experimental program was to perform tests on the Rancho Seco spray ponds 'in accordance with the ASME Power Test Code - No. 23 - Atmos-pheric Water-Cooling Equipment, and with. prevailing meteorological conditions for ' the' purpose of: (., 1. Establishing the ' thermal performance capability of the ponds; 2. Establishing the drift loss as a function of wind speed and q heat' load; 3. Determining the spray nozzle efficiency. From the basic experimental results the overall pond performance is to be

)

a, calculated for conservative meteorological conditions and.the heat load character-istic of the LOCA (SMUD FSAR) to verify the design thermal performance and 'f ' the adequacy of pond inventory to sustain operation for the critical 30 day lI period. A. III. Test Program and Procedures 1.. A. Test. Program .[, Four tests were conducted as follows ji West Pond Test No.1 - 24 hours -at Heat Load of 3.0 x -10 Btu /hr. Continuous I 7 -Spray.

3 A East Pond Test No. 4 - 9 days, No Heat Load, Continuous Spray. f, Tests 1 and 4 were started simultaneously on May 18, 1973. Tests 2 and 3 ) followed test'1 on consecutive days. Thus the first three days of test 4 were run concurrently with tests 1, 2 and 3. This procedure allowed comparison of i load and no load operation under the same wind conditions. It also provided an opportunity to observe the interaction between the ponds. Figure 1 shows the orientation of the ponds with respect to each other and other plant components. ( B. Test Procedure \\. The procedures. followed and the instrumentation employed conformed to the f ASME PTC-23. Figure 2 is a schematic diagram showing the layout of the West Pond and the instrumentation locations. Similar instrumentation was provided I as needed for the simpler test performed on the East Pond (Test 4). Table 1 lists the instrumentation associated with each of three West Pond data stations. L Also included is the frequency of reading and the precision of the instrument. t .t Circulating pumps were turned on and spray operation started the day prior to the start of testing. The-heat load was applied to the West Pond several -(- hours before the start 'of testing so that the startup transient had passed and I the pond was following the meteorological conditions. .I, C. Lleasurements and Instruments 1. Wind Speed and Direction Wind speed and -direction were recorded continuously during all four tests b .using a Weather Measure Corp (Systron-Donner) recording anemometer located on '[ the west side of the West' Pond (up wind side most of the time). The prevail-k. ~-ing wind is out of the southwest in this season and the direction was usually 'between L220 and 270 degrees (true). Occasionally in early morning hours during j lulls the direction shifted to south or southeas :. lJ. e, .m

,. (.. A precision hand-held anemometer was used at data station.4o. I to read the wind speed each time psychrometric data were read at the three stations.on the 4:- west bank of the West Pond. Records were obtained from Mather Air Force Base, the nearest meteorological station, for comparison. ?!ather is approximately 20 miles north of the Rancho ~. 3-Seco site and is in a similar meteorologic location. 2. Psychrometric Data i Wet and dry bulb temperatures were recorded at three up wind stations on l' the west bank of the West Pond using Weather Measure Corp. battery powered 3 psychrometers which had been modified by installation of 0.1*F precision ther-mometers. ( 3. Pond Volume I A calming well was installed on the outboard side of the pump suction sump '[' structure near the north-south axis of each pond. Vernier electric contact point gages having a precision of 0.001 foot were mounted in the calming wells

i ~(

to measure the level of the water in the ponds. Each pond was surveyed before filling to obtain reference points for defin-b ing the bottem and sioning side surfaces. The survey data were used to calculate j! a detailed relation for pond volume vs depth. These results are presented in

C

-Appendix C and are consistent in precision with the depth readings. ,a i Pond volume changes are accurate to within i 500 gallons or better. w 4. Water Temperatures and Catch Pans ,p N, Water temperatures were measured with mercury in glass thermometers and ]: thermistors to within t 0.1*F. Itercury thermometers were installed in bubbler [ ' columns to provide flow.over_the immersion length. Thermistors were mounted in the pond a:: shown in Figure 2 and one was taped to a spray nozzle pipe and wrapped with~ insulation. Good agreement was found between it and the mercury IU lu ill.8

a.- ? 41 5 i ( thermometer on the return line. a-Catch pans 1 foot in diameter and 4 inches deep were equipped with an over-flow line. A thermistor was mounted at the mouth of the overflow line to ensure 'l ^ that it responded to changes in spray water temperatures. These catch pan ther-mistors measured the temperature of the spray water falling on the pond surface. 1 A total of seven fixed catch pans were employed to obtain a representative dis-tribution of the spray water temperature falling on the pond. A special catch i pan was designed to measure both the flowrate of the falling spray and its tem-j 4 - perature at impaction. This device was designed to be towed thus permitting a j larger number of locations to be surveyed. L The towed or movable catch pan also carried a rack of thermistors to meas-ure water temperature at various depths in the pond. It was employed primarily during test No. 3. All themistors were individually calibrated. During tests they were con-nected to a bridge circuit whose unbalance was recorded on a Honeywell Brown L Electronic multi-point recording potentiometer. Accuracy of t 0.1*F was achieved. 5. Flow Measurement. ( Pitot tube stations were mounted on the 24 inch stainless steel return 1 lines in the ponds midway between the last fitting at the pond sill and I the first vertical header. Several sets of 90* traverses were made in each pond to establish an accurate relation between the flowrate and the spray head pres-( sure. The pitot tube differentials were observed on a manometer containing Meriam Fluid No. D 2883 (Sp. gr. 2.95). The differentials were on the order b of two feet and' could be read to 0.01-ft. However flow oscillations caused (- variations of t 0.05 feet (or more in the West Pond at times) so that a small amount of scatter of the data points in velocity profiles resulted. Flowrates were calculated, using the standard equal area method, from the faired velocity 7O j

.-.y f 6 1 p i i profiles. These results:are presented in Appendix A. ~ . p-Make-up water flowrate was measured on a precalibrated Haliburton turbine l meter-(+ 0.57. accuracy). The makeup water was injected into the system at the I 1 heat exchanger inlet. j IV. Discussion and Results A. Water Loss W. j Water loss from the ponds was found from the change in pond level and the metered make-up water,if any. The entire nine day test w'as run without make-up i i water addition. The West Pond level and make-up flowrate are given in Figure 3. East Pond level is shown in Figure 4. These data were used to calculate aver-age loss rates for the intervals between pond level measurements. I Wind data from hand anemometers was averaged and found to compare well ,t. with the recording anemometer. For tests 1, 2 and 3 the hand anemometer data J were used to obtain the wind curves given in Figures 5, 6 and 7. Wind speed from the recorder is the basis of the curve for the 9 day test. (Test No. 4) (~ shown in Figure 8. During periods of high wind the wind was very gusty. For l example when the mean wind speed was 12 mph the variation was often t 6 mph. s, This condition required fairing variations of high and moderate frequencies in tL order to process the data. Figures 9,10 and 11 give the total water loss rates vs. time for Tests 1, l" ~ Combining these with the wind data gave the relationship between the 2, and 4. l . total loss rate and wind speed sr.)wn in Figures 12, 13 and 14. Taking the inter-L cept of the curves on the ordinate to be the evaporation loss, gave drift loss curves plotted in Figure 15. This procedure assumes that the evaporation rate is independent. of the wind speed. The percentage of total heat loss which is 1'" 'due to evaporation may vary slightly but such an effect has yet to be established. [ The remaining question then is how the evaporative fraction compares for each test. .. Lt. j

C' It is'not li'<ely that these results are an accurate indication of the per-1t cent of heat transfer by evaporation for these two runs or a general dependence upon the magnitude of the heat load.

The value for Test No.1 is probably too high.while the one for Test No. 2 is too low. In spite of this the data proces-

. _.~ - - (?. g L p {j dual nozzle efficiencies vary from a high of 0.686 to a low of 0.125. p This wide range' of nozzle efficiencies is due to a major extent to the interaction between nozzles. Nozzles located downwind of the edge of the spray } pattern received air that has been humidified whereas ambient wet bulb tempera-ture is used to calculate n. Thus nozzle location is important and wind speed { and direction are important in detemining the effective wet bulb temperature available to each nozzle. This same effect would be observed (to a lesser f I extent) for a single nozzle if its efficiency were measured as a function of C position in the spray pattern on the pond surface. For the large group of nozzles in a rectangular pattern the effect of wind 1 '[ direction tends to confuse the dependence of efficiency on nozzle position. We have adopted the view that the distance across the spray field from the upwind I edge, measured in the direction of the wind, is the relevant length for correl-ating the efficiency. This concept is sound for the case when the wind domin-ates the air flow within the spray region. At low wind speeds the natural con- [ vection plumes dominate the air flow, i.e., the plume induces air flow into the i spray region all around its periphery, even on the downwind side. This phen-a l-omenon was observed at night during periods of low wind. The lighting around the pond made the plumes especially visible. For the natural convection case L we would then expect a non-monatonic variation in n observed along a line ,s( through'the pond in the wind direction. Figure 16 illustrates the variation of efficiency in the wind direction q. L-for high moderate and low wind condition. These results corroborate the ideas i expressed in the previous paragraph. For design purposes it is desirable L to know the average value of K for the entire pond. Thus a rational method for averaging the measurements of individual catch pans is needed. We l

U U

k

[ T 9 r have used the explanation put forward above as the basis.for seeking two pat-terns 'for weighting individual catch pan results, one for high wind where wind dominates and one for low wind where natural convection dominates. (. The averaging patterns selected were found by trying several plausible -schemes and comparing the results with the value of n calculated using pond temperature. To do this only data were chosen for times when pond and wet bulb I temperatures were particularly stable. Figures 17 and 18 illustrate the pat-i terns adopted for low and high wind conditions, respectively. The question arises as to how to define " low" and "high" wind. For winds up to 5 mph only the low wind pattern was used. For winds between 5 and 7 mph both patterns were used and the difference in the results is not large. Above 6 mph only the t high wind pattern was used. Figure 19 presents these results and constitutes s j a reasonable correlation of the average nozzle efficiency with wind. -

t, For design, average values of n in the vicinity of 0.40 to 0.45 appear to

'. ~

be justified. This conclusion is consistent with the results of our analysis of intermittent spray operation. We have compared the results of our computer C model with the experimental data of Test No. 3 for various values of n. For 6 = 0.45 the pond temperature agrees closely for the prediction and experiment. t C. Flowrates and Heat Loads ~i' The results of pitot tube traverses are presented in Appendix A. The

j results of three flow measurements each on the West and East Ponds during these 1

tests plus five additional measurements made by David Abbott of SMUD subsequent l iil) to the UC tests are presented together in Figure A-1 as flowrate vs. spray ll manifold pressure. The mean line drawn ;hrough the data points is the recom-N mended correlation for both ponds and is with 3.5% of all data points. [ The heat load on the pond was calculated from the product of the mass flow-M fi

=_ m. --w=-- M'. 10-U: rate and the temperature difference between the water leaving and returning to the pond.- n-Table 8 below gives the average conditions for the four tests. Table No. 8 ( Flowra+e_, g m Heat Load Btu /hr West Pond Test 1 15,000 3.0 x 10 7 j West Pond Test 2 16,500 6.68 x 10 16 pr p West Pond Test 3 7.9 x 10 y aO L East Pond Test 4 15,900 0 l' i-D. .Dond Interaction During Tests 1,2 and 3 the wind was generally from the west or southwest and therefore the air crossing the West Pond became humidified before reaching s the East Pond. The effect of the upwind pond on the one downwind has been a matter of speculation. Comparison of wet bulb temperatures for the two ponds a shows that there is a small effect. Figure 20 shows this comparison for Test No'. 2 and reveals that the downwind pond sees about a 1*F increase in wet bulb temperature above ambient. At the design load on the plant this effect would t be slightly more than twice this amount. 3-E. Intermittent Operatien .I.' The purpose.of intemittent operation is to conserve water when the con- { tinuous spraying is not needed to hold the pond temperature at the design level. L hhen the pond water temperature is low the circulating water is' put on bypass. 4 L In this condition the water from the heat exchanger is returned directly to the pond and is directed away from the pump suction to avoid short circuiting of the pond. It was observed in Test No. 3 that the high kinetic energy of the [ water entering the pond promotes large eddys and rather good mixing. Short a C I

O, 11 L p -- 4,, circuiting would be most evident by a rate of rise of the pond outlet tempera-ture exceeding the rate for adiabatic conditions and perfect mixing of the return water in the pond. In each case that the flow was on bypass the actual ~ rate of rise of temperature at the pond outlet was equal to or less than the L ideal rate. 6. i F.

The heat load is that pre-r~ sented in SMUD FSAR , Figure 9A-30 of Amendment 19. The meteorological con-L ditions used were those based on June 1951 (High Wind) and August 1958 (High ~. Wet Bulb Tcmperature) as presented in Tables 9A-7 and 9A-8 and Figures 9A-22 and 9A-26 of Amendment 19*. The diurnal variation of wet bulb temperature was i, I.. assumed to follow the latter two figures for each of the 30 days. Input information on drif t loss was taken from the drif t correlation pre-u sented in Figure 15 (The curve from Test No. 2). Evaporation was assumed to be l' 1007. of the heat load. Constant h was used parametrically. Before proceeding to discuss the results some of the major features of the problem may serve to aid in understanding the results. Each pond is designed t p to hold 2.7 x 106 6 lb of water. The circulation rate for gallons or 22.5 x 10 m each pond is 16,000 gpm or 8 x 106 lb /hr. The high wind condition, 14.3 mph, m will produce a drif't loss of 0.937. or 7.44 x 104 lb/hr of spray operation. The integrated energy input over 30 days corresponds to an evaporation loss of ( 28.3 x 106 lb - m The intended operation of the pond for the critical 30 day period is to L~, spray intermittently to hold tne pond temperature at or below 95*F. Water from the unheated pond is assumed to be available and will be transferred to the heated pond. The above data indicates that'by this method there is ava41ahla 16.7 x 106 lb of water for the drif t loss requirements. Based upon the experi-t. a mental results of Test No. 3 which indicates the fraction 0.37 as the time 7 BTU /hr (compared to the needed for spray operation at a heat load of 7.9 x 10 .I

heat transfer during spraying operation in the present tests (as inferred from lg, the intercepts of total loss curves) was 20% and 35% for the two heat loads. 6' 20% sensible heat transfer corresponds to 5.66 x 106 lb, reduction in water loss. I G. Summary of Computer Results ik ~ As indicated above the pond water inventory is inadequate for the 30 day !I -{j period following LOCA for the high wind (June 1951) condition with continuous spraying. For the high temperature condition (August 1958) the inventory is 'k-still not quite adequate for the 30 day period on continuous spraying. A com-puter run for this case shows that the diurnal peaks in pond temperature are (_ within the design limit. The pond starts at the mean ambient wet bulb tempera-4 4 t, ture of 70*F and rises to 92.6'F and then declines due to low wet bulb temperc-g ture at night. On the second cycle the peak temperature is 94.2'F; on the third 'I-91.0'F and then lower for all succeeding peaks. This calculation uses an average I nozzle efficiency of 0.45. The results shows that intermittent spraying may

be used during these ambient conditions. (~'[ Results for the critical meteorological conditions are given in the follow-ing summary. -9 L [u om ! i ibs 1

As it noted in the analysis all the pond surface heat transfer is considered to-be f 3 evaporative in the evaluation of mass loss. The intermittent operation cycles the pond' temperature between 90 and 95'F. These results show that the pond water inventory is adequate even for the 4 a poorest nozzle efficiency. From the correlation presented in Figure No.19 the II best choices for 5 would be 0.38 for June 1951 conditions and 0.52 for August T' h 1958 conditions. J, l c i 1
