crw ey ALPHA-510-0 Page 5 L PARTI L Introduction Before PANDA can be employed in experiments intended to simulate the behavior of the General Electric SBWR containment, a number of system charactenzation tests must be performed. These include heat loss tests and system line pressun drop measurements. The heat losses from various system components are needed for calculation of energy balances, which in tum are used to assess system performance. System line pressure drop characteristics must be mesured to ensure that the PANDA facility is adequately simulating the pressure loss charactenstics of the full scale SBWR system. Accurate measurement of heat losses and pressure drops are necessary to teliably model the system with computer codes. This report includes a model for nlminion of the PANDA facility heat losses and a brief outhne of the yini for performing hear hoss tests. This is followed by a presentation of the simple model used to et+- S system line pressure losses. Also included is a rough outhne of the experimental procedure for system line pressure loss tests. The two models are part of the Test Plan ( Pan 1 of this document) while the procedures are included in Part II.

2. Pressure Drop Tests The pressure loss cW~ietics of each PANDA " system line" (the piping intended to simulare the lines and volumes connecung the SBWR drywell, wetwell, GDCS tank. PCC enadaaem and RPV) must be measured to ensure that the lines ad-"=a!y model their full scale counterpens. The pressure drop along a y=caular line can be expressed as:

1K AP 2 p A'ris' (1) where rir is the water or gas mass flow rate, A is the line cmss sectional area, and K is the overall loss coef5cient for the line. PANDA has been scaled so that system mass flow rates are 1/25 that of the full scale system. The general scahng criterion requues that the pressure dmps across the PANDA system lines and those of the SBWR system be equal for mm-d g flow rates. As a can=~=m the value of K/A' for each PANDA system line should be 625 times (i.e.,25') that of the corresponding SBWR line. The purpose of these tests is to measure the effective value of K/A' for selected system lines. Separate tests with pure air and pure steam are performed with system lines intended for steam and/or air flows. Air tests at room temperature are desirable b~== uncenamties associated with elevated temperannes and steam condensation and/or flashing along the lines are elimi=ad Data from the two r 9es of tests will be compared to venfy that the K/A' is similar for steam and air flow. However, the main stea lines will be tested only with steam because air tests are impractical. Lines intended for liquid flow are tested with water.

\\ g b W" ,co; l ' ALPHA.510-0 ' a Page 6 1 l 2.1 ExperknentalProcedure- ' 2.1.1 Air Tests The general approach for these tests is to pressurize selected vessels and then open the approprime valves so that I air flows along the desired lines. Pressure drops along.the lines are relatively small, asamag that Gow is not. l 7 choked at any of the system line on6ces. These tests provide measurements of K/A* over the full AP range expected for eachline. e i The PCC' feed and vent lines are tened togaher. All vessels except the werweUs are ; M o about 1.6 bars t and then a single vent line valve is opened to allow air-flow along the wc ; --{=; feed-vent line pair into the wetwell. As the system W% vortex flow meters measure the volumetnc flow while FT 100s and absolute pressure trarmnumers measure the gas temperature and piessure and diffemanal pressure tran=nina's ' measure the differenual pressure. The elapsed time for depresamzation is roughly fiAsen muutes. The system is then repressunzed and the next feed-vent line pair is tested. h is noted that the gas temperature change produced by the depressunzation, assummg nrhaharr, quasi-static d--aa==mion, is 38"C. If it is deemed necessay, K/A* l can be measured at higher presanes by ha-iaa'ag the ir. gimion at a higher pressure. However, the. manmum AP beeween the drywell and wetwell should be kept below about 0.6 bars to....'... gas temperature 'l changes dunng decompression. i =! .I 2.1.2 Steam Tests - l These tests are similar in nature to the air tests except that seem from the RPV generates the flows and pumane f drops. In general, a steady mass flow rate at a constant temperature is established in the lines ofinterest and then-1 the flow ime, differennal pnesure, =h=hwa pressure, and temperature are recorded. The flow rate is =Warly meressed (or decreased), hm-a and a new set of toensurements is recorded. The flow rate can be ahered by changmg core power or using a steam bypass through vents to the atmosphere. l e The main steam, PCC feed, and vent lines may, in pnnenple, all be tested simultaneously. However, it may prove r more convenient to test a single main steam, PCC feed, and vent line at a time so that the mass flow rare can be - more readily stabihaed at the desinut levels. The wetwells are empty dunng these tests (or the water level is well below the vent pipes). Isolanon valves on the main steam line not under test ternan closed and possibly the one or ~ f two PCC feed lines not under test me isolated. 2.1.3 GDCS drain and Equalization Lines The isolation valve on the GDCS drain line is initiauy closed so that the tank can be filled to the top with water. .j All isolation valves on the RPV are closed except those on the main steam lines. The RPV water level should j initially be telow the drain line exit so that the manmum GDCS flow results at the beganmg of the test. Open the valve on the drain line to initiate flow from the GDCS irso the RPV. The test ends when the GDCS and RPV warer Ir vels equalize and the drain flow stops, which requurs roughly thiny minutes. .l l The ~In=hr=rion line test is similar to the GDCS drain line test. Close all valves on the RPV except those on the main steam lines. ' Fill the wetwell with water until the level reaches at least 4.6 m, producmg the manmum driving head expected during a bottom head drain line break transient. The RPV water level should be below the CKlu2ItNion line penetration on the RPV. Open both equalimion line isolation valves to aUow water to Dow into j the RPV. The test ends when the werweU and RPV water levels equahze, which requires less than an hour. .] k h -4. .-w

3. Heat Loss Tests 3.1 Heat Loss Model Heat loss tests are conducted by heating the vessels with steam and then allowing them to cool'after each har been isolated. An energy balance on each vessel during this cool-down phase can be written as (2h d

Q = dt pudV + C t (2) wheie Q represents the total vessel heat loss rate and C, denotes the heat capacity of the vessel. The term u refers to the intemal energy of the fluid (steam and water) within a vessel of volume V. De time tNe of change of fluid intemal energ" must be da-mia~i induectly, through temperanne measurements, and so it is desirtle to write the heat losses in terms of a single heat capacity and temperange. G = Cf (3) i This appmach assumes that a single temperature can be used to represent the temperanne of the entire vessel as f well as the steam and water inventories. His is a reasonable assumption harama the vessels are well irimimad minimidag gradients along and across the vessel walls. Also, the vessels are steam-filled at the t- - hg of the test and so the entire gas space and inner wall surface will follow the steam saturation temperanne as the vessel cools. The water inventory is small for these tests so the enndamma will closely follow the vess-1 wall temperature. With such a largely uniform temperanne distribution, a few temperanne measurements around a vessel can be averaged to arrive at a representative tempenture, and thus a single temperature r.a.s the thermodynamic state of the system. Using egns. 2 and 3, the total system heat capacity is wrinen as: C=d f (4). dT, pudV + C., The first term the heat capacity associated with the Duid inventory, must be written in terms of measurable quantities. Define this as C,, the heat capacity of both the liquid and gas, and integrate separately over the volumes contammg enndan=a and steam (subscripts I and g. respectively). De Duid heat capacity is now wrinen as: d Ci = -[ Min, + Mau,} (5) where u, and u, are the volume averaged intemal cry.rgies of the liquid and gas, respectively. He above is then expanded by taldng the derivatives with respecs to temperance Since we have made the assumption that the liquid and gas are at a uniform temperanne, the notation sigmfymg average intemal energy is dropped. Equation L [5]is reminen as: Cr = uu #' b N + u, dT" + Mu dT (6) +M dT dT

%)- l s: c i l k . ALPHA-510-0 'f _Page. 8-3 p-- The above expression is simplified by using the following relations. For an ideal gas: .b - = c., (7) . dT - m while foranincompressible fluid: dui - W - =.c., = c,, (8) dT For a closed system consisting of steam and condensate, a decline in the stam inventory due to condensation is identical to the increase in liquid inventory. Therefore: l dMs dM, i (9) =- i dT dT Equation 6 is then rewriaen as: dM,[u, - u } + Mac, + Ms,, Ci= dT o c 00) a f The change in steam inventory cannot be measured directly and so it must be rewritten in terms of quantities that - L can be detenmned through temperamre measur=,nre. 'Ihe mass of steam is simply the product of the density and total volume of the steam and so one can write:

dM, = - V d P, + p' dV,

' 01) - dT dT. dT. Condensate is connanally dramed from the vessels dunng heat <sp and so the water inventory is aa li-iw t the a outset of the cool < lown transient. Condan==e* forms during the cool-down, but its volume is small compared to j that of the steem. Thus the second term in the above equenon can be neglected and the heat capacity due to the vessel fluid inventory written as: Ci=Vd p'[u, - u } + Mic, + Ma,, r c (12) dT The steam density change with temperanne and the fluid internal energies are obtained from steam tables. The. first term is related to the condensation occumng as the vessel cools, causing the steam density to drop. The last. 3 two terms are simply the bulk heat capacities of the steam and e>=daa**'a which are small compared to the fust - term. This is illustrated by fig.1, where the heat capacity contributions in'a drywell cool <iown from 140*C to 90*C have been ploued. It is assumed that the water inventory at the beginning of the test is negligible. The three ' terms in egn.12 are designated C,,, C, and C,, respectively. The graph clearly shows that the steam and i condensate heat capacities are small compared to the heat capacity associated with condensation. t .O t + ?

( ,y e-i ALPHA-510-0 ~l Page 9 3.2 Experimental Procedure All vessels are heated using steam from the RPV and air is purged from the system by venting as the system pressure rises. Water is continuously drained from the vessels to mmtmize the condensate inventory. The steam supply is tumed off after a pure steam atmosphere near four ban is established (P,, = 3.6 bars @ 140*C). Valves on the PCC feed. vent, and condensate lines are closed to isolate the condensers from the remainder of the system. The vessels are then isolated from each another by closing valves on the main steam lines, main vents, pressure eqmhnrion lines, and all valves on the auuhary steam lines. This is followed by initiation of temperature and pressure measurement recording with the data acquisition system. The amount of time necessary to conduct these ' tests is illustrated by the cool-down curves plotted in Sg. 2. These have been calculated using estimated vessel heat losses. 4. Data Processing and Analysis 4.1 Pretest During the pretest setup and test operation of the test facility the operators will monitor the required instrumentation identified for these tests in Table 11.1. The operators will check whether or not redundant measurements are consistent and perform other congruency checks as possible to verify that the instrumentation and data acquisition system are working correctly. - 4.2 Post-test / Quick Look After each test, a quick look at the data will be performed in order to provide the information necessary to I proceed with the next test. This quick look will be focused on identification of required instruments which have failed and verification that the objectives of the test were achieved. This quick look will include a cursory review of time history plots covering the full test duration for all of the required instnaments. ] 10; 140' m o 6 x o ',s m X c' 's g k 120. ,-N e f 1- ',',s e e, u \\ Wetweit g U $100' ',.N a e 8" s a S $ 0.1 - DW so' 80 .160 0. ..40.. ..80 100 120 .20 60 Temperature ('C) Time (hours) Fig.1 Contributions to tb aywell heat capacity Fig. 2 Cool-down transients for selected PANDA over the course of a cool do a n test. wessels.

This data reduction will include time history plots of all the required measurements covering the full test duration. These results will be reviewed and reported in the TR. 4.4 Post-test / Final Test Report The Final Test Report (FTR) will transmit all the data for the system line pressure loss and the heat loss tests. It will provide detailed information on the test instrumentation, test conditions and the format for the data. In addition, samples of key data will be presented in plots along with simplified sketches of the test facility configurations during testing. 4.3 Data Records The digitally acquired data will be recorded in real time for the entire duration of the test. Immediately after the test, a copy of the data file will be created in order to have a permanent record of the dt.ta file. Also to be recorded with this data file is allinformation required to perform subsequent processing of the data. 4.4 Data Sheets The following data sheets will be prepared for each test for inclusion in the Test File (TRF). "Ihe test name will be printed on each sheet.

1) print table containing the list of the measurements with their main characteristics (identification, span, calibration constants, associated error, location on the facility, measurement channel number and sampling frequency)
2) print tables of mean, standard deviation, minimum and maximum value of the K/A* values for each line tested.
3) graphs of all required measurements as a function of time (time histories) for selected test periods.

5. Instrumentation Requirements The instrumentation required for the system line pressure loss tests are listed in Table i1.1.

The instrumentation needs for the vessel heat loss tests will require a representative sarrpling of temperature j sensors for each vessel being tested. The test engineer should ensure that there are function d sensors in the upper, j middle and lower sections of each vessel and that in general at least 30 to 50 % of the tunperanne sensors are j functioning as evidenced by periodic update of the reading displayed on the control termmal screen.

The initial conditions are not necessarily defined for the whole facility'at any one point' but will be - 'l specified for the relevant portions of the facility in a given test. In general, the performance of sections 10 i through 13 apply to all test sections, and for interruptions in testing activities of gresser than three to four l bours, these sections may need to be re yr L.-.ed.

g ALPHA-510-0 Page 17 80 Main Steam Lines Pressure Loss Tests With Steam Each main steam line is tested at maximum, minimum, and intermediate volumetric flow rates. The same is performed for each condensor. Since the condensors, by design, operare independently, it is not possible to accurately predict flow rates through the condensors when more than one flow path is available. Thus the procedure requires that each condensor feed / vent line~is tested singly while flow paths through the remaining two condensors are closed. 80.1 Check / adjust Vessel Parameters All vessels and pools should be empty except the RPV, which should have a minimum water level of 6 m. Check that the following levels are approximately zero: ML.S1, MLS2 MLDI, MLD2, MLU0, MLUI, MLU2, MLU3. Verify that MLRP.1 is at least 6 m. ii 81 System Line-up and Initial Conditions 81.0 Set valve positions according to the STARTUP status 81.1 Check / position valves - Open/ check open valves CC.SIV and CC.S2V r CC.RPV CB.PlF CB.Plc and CB.PlV i CB.P2F, CB.P2C and CB.P2V CB.P3F, CB.P3C and CB.P3V CB.GPl and CB.GP2 CB.MSI and CB.MS2 CC.MS! and CC.MS2 CB.GRT.1 and CB.GRT.2 81.2 Heaters on at full power: MW.RP.7 a 1.5 MW 81.3 Steam flow through the drywells and condensors is initiated after boiling in the RPV begins.
