1. INTRODUCTION This Test Plan contains a general description of the PANDA test facility including the instnimentation and data acquisition system. In addition, this Test Plan specifically covers the test program objectives, the experimental facility configuration, the test facility control and safety, the test instrumentation, the data acquisition system, the data analysis, the test conditions and the test reports for the Steady-State PCC (i.e. separate effects) Test Program.
2. TEST PROGRAM OBJECTIVES The objectives of the PANDA steady-state PCC tests are to provide additional data to: (a) support the adequacy of TRACG to predict the quasi-steady heat rejection rate of a PCC heat exchanger, and (b) identify the effects of scale on PCC performance.

The approach to achieve these objectives is: a) rneasme the steady-state heat removal capability with various inlet air mass fractions for steam flows approaching the PCC design rating. b) perform counterpart PCC condenser tests to those run at PANTHERS and GIRAFFE

3. PANDA TEST FACILITY DESCRIPTION 3.1 Introduction The tests specified in this document will be performed in the PANDA facility, a large scale, integral system test facility which models the SBWR compartments and systems which are important to the long-term contamment cooling following a LOCA.

The PANDA facility was designed for transient integral systems tests. Section 3.2 gives a general description of the transient test configuration, and Section 3.3 describes the main components of the facility in greater detail. i

r I ALPHA-410-1 Seite 8-The steady-state tests, to which this test plan is applicable, utihze only a portion of the complete facility. Section 3.4 describes the configuration for the steady-state tests. 3.2 General Description. The facility has been designed to exhibit thermal-hydraulic behavior similar to SBWR under LOCA conditions beganing approximately one hour after scram. The global volume scaling of the facility is approximately 1:25 with a nominal height scaling of 1:1. The SBWR components which are modeled in the facility are: the Passive Containment Cooling System (PCCS), the Isolation CWar (IC) System, the Gravity Driven Cooling System (GDCS), the Reactor Pressure Vessel (RPV), the Drywell (DW), the Wetwell (WW) and the connectmg piping and valves. Electric heaters provide a variable power source to simulate the core decay heat and the stored energy in the reactor structures. Rigoroas geometric similarity between SBWR containment volumes and test facility vessels is not aa ~y to capture the fundamental features of the containment response and has not been attempted. The PANDA vessels are connected with scaled piping components to represent the connectag lines in the SBWR. The test facility vessels and piping connections are shown schematically in Figure 3-

1. The arrangement, elevations and volumes of the major vessels are shown in Figure 3-2.

The SBWR RPV is simulated by a vessel containing electric heaters. The top of the heaters is at a relative elevation which represents the top of the active fuel (TAF). With the RPV simulator partially filled with water the heaters will generate steam which is discharged to vessels representing the SBWR drywell. The drywell is represented by two vessels cannar*M by a large diameter pipe. The werwell is also represented by two vessels. The bottom of the wetwell vessels ate filled with water to the same relative elevation above TAF as the SBWR suppression pool. The wetwell vessels are caa=ac*ad by two large diameter pipes, one in the gas space and one just below the water surface. The purpose of using two connected wetwell/drywell vessels is to permit a simulation of multi-dunensional or asymmetric conditions (temperature, gas fraction). The elevation scahng of 1:1 has been applied to the parts of the system which are above the top of the SBWR core. The PANDA scaling is evaluated in Appendix B.5 of NEDO-32391 [1]. 'Ihe PANDA facility includes three scaled PCC condensers and one scaled IC unit (representing the scaled capacity of two SBWR IC units). These are mounted above the :irywell vessels at the same elevation above the TAF as in SBWR. Two of the PCC units are enanactad to one of the drywell/wetwell vessels and the third PCC is connected to the other drywell/wetwell. The IC unit is connected to the simulated RPV. All four condensers are submerged in waar in tanks representing the PCC/IC pools. Figure 3-3 shows the IC/PCC condenser test units. The SBWR GDCS pools are represented in PANDA by a single GDCS vessel. The elevation of the GDCS vessel is representative of SBWR, but the volume of the GDCS vessel is not scaled the same as other PANDA vessels. It is not naca y to scale the volume of GDCS water in order to model the part of a SBWR LOCA transient to be tested, because the GDCS tanks primary function during the time period to be tested is to act as a collection tank for the PCC condensate drain flow. The tests will be conducted at temperatures and pressures representative of SBWR postulated LOCA conditions after initiation of the GDCS. To assure these conditions can be tested in PANDA,

t ALPHA-410-1 Seite 9 l i the facility has been designed to 10 bar (145 psia) and 1800 C (3560 F). These conditions exceed SBWR LOCA conditions after initiation of the GDCS. I 3.3 Component Description 33.1 RPV 'Ihe PANDA vessel used to simulate the RPV is cylindrical with a nominal outside diameter of l 1.25 m and a nominal volume of 22.8 m. The vessel is scaled to the SBWR RPV volume above 3 the bottom of the reactor core. The simuided decay heat power to the test facility is provided by y i electrical heaters placed near the bottom of the RPV. The top of the heaters is at the same relative elevation as the top of the active fuel (TAF) in the SBWR. A cylindrical sleeve inside the RPV is used to represent the SBWR core shroud and chunney. The steam separators and dryers are not simulated because they have no significant effect on the long term release of steam to the l 4 containment. The PANDA heaters have an installed maximum capacity of 1.5 MW. The scaled l j decay heat of the SBWR at one hour after scram is approximately 1.0 MW. The remmning 0.5 MW j f can be used to simulate the RPV internal energy. A controller has been provided for the heaters to accurately follow any given energy release transient within the limitations of the installed capacity. i f 33.2 Drywell The SBWR drywellis represented in the PANDA facility by two cylindrical vessels connected by a l l large diameter pipe or duct. The vessels are designated as "DWi" and "DW2". Each of the two i vessels has an outside diameter of 4.0 m and nommal volume of 90 m3. The connectmt pipe between the drywell vessels has a volume of 3.5 m3 and a diameter of 92.8 cm. The total voluine of J the PANDA drywell has been scaled to the SBWR upper and annular drywells, i.e. it does not melude the lower drywell negion. Access to the inside of both drywell vessels has been provided. a 3.3.3 Wetwell i The PANDA facility has two connected vessels to represent the SBWR werwell. The wetwell 1 vessels are designated as "WWi" and "WW2". The two vessels are cylindrical with an outside diameter of 4.0 m each with a volume of 117 m3. Each vessel is partially filled wi:h water to represent the SBWR wetwell pool. There are two large horizontal pipes connectmg the wetwell vessels; one in the gas space above the water level (diameter of 92.8 cm and volume of 2.7 m3) and one just below the normal water level (diameter of 142 cm and volume of 6.3 m3). Wetwell vessel j WW1 is directly below and provides support to drywell vessel DW1. Vessels WW2 and DW2 are j similarly arranged. (See Figure 3-2) Access to the inside of the wetwell vessels has been provided similar to the drywell access. The wetwell vapor space was scaled to preserve the pressure response of the trapped non-condensable gas in combination with steam. The total wetwell pool surface area was scaled to correctly represent the evaporation / condensation processes at the pool surface. I The pool water depth extends sufficiently below the PCC vent line terminus to provide a representative volume of water with which the uncondensed steam vented into the suppression pool can mix. The suppression pool depth is large enough to cover the topmost LOCA (horizontal) vent 1

I ALPHA-410-1 i Seite 10 L { and the wetwell-to-RPV equalization line. However, the total depth of the pool is reduced from the depth of the SBWR suppression pool by elimination of the region at the bottom of the SBWR pool which does not participate in the long term mixing. I ' 3.3.4 PCC Condenser Pool /IC Pool The PANDA facility represents the PCC/IC pools with four rectangular tanks mounted above the l drywell vessels at an elevation above the top of the RPV heaters the same as the bottom of the j SBWR IC/PCC pools are above the core TAF. The tanks for the four condensers can be interconnected below the bottom of the pool to allow free passage of water and maintain the same water level in each compartment. The auxiliary system provides demineralized water to the pool prior to a test and also drains the pool when needed for maintenance, modifications or repairs. Steam generated in the pool during testing is vented to the surroundmgs and maintains the pool surface at atmospheric pressure. The pool tank was sized to provide sufficient water to keep the condenser tubes covered for approximately 24 hours. A water supply is available to refill the pool during the course of an experiment. The pool walls are insulated to limit the heat loss to that t associated with net vapor generation. 3.3.5 GDCS Pools The three SBWR GDCS pools are represented by a single tank in the PANDA facility. Since 4 PANDA was designed to model SBWR long-term cooling performance following the initiation of GDCS injection (i.e. scram + 1 hour), the GDCS tank is not scaled to the full GDCS volume of SBWR. The PANDA GDCS tank is a cylindrical vessel with an outside diameter of 2.0 m and a volume of 17.6 m3. The bottom of the PANDA GDCS tank is at the same elevation as the bottom of the l PANDA drywell and is the same elevation above the TAF as the SBWR. Durmg a test, the tank collects the condensate from the PCC units and retums it to the RPV. 3.3.6 PCC Condensers l The three SBWR PCC condenser units are represented in PANDA by three condenser units scaled 2 1:25 for the number of tubes and header volumes and scaled 1:1 in tube height, pitch and diameter. l This provides a heat transfer surface area of 1:25 of each SBWR unit. Each of the PANDA PCC units has 20 tubes welded at the top and bottom to headers having the same diameter as the SBWR units. Each of the three units has the appearance of a slice of one module of a two-module SBWR unit. This scaling is expected to ensure that secondary side behavior of the PANDA condenser unit is representative of the SBWR units. Since the PANDA condensers are only small segments of the SBWR condensers, side plates have been added to guide the flow through the tube bundle in a j manner similar to that expected in a complete condenser. The PANDA PCC units are shown in l Figure 3-3. One of the PCC units (PCCl) receives steam / air mixture from DWI, vents to WW1 and drains the ch=** to the GDCS tank. The other two units (PCC2 and PCC3) receive inlet flow from DW2, l vent to WW2 and drain the condensate to the GDCS tank. One PCC unit, PCC3 has been constructed so that it can also receive steam duectly from the RPV in order to test the steady-state performance of the condenser (See Figure 3-4).

t i ' ?. ALPHA-410-1 Seite 11 l i l 3.3.7 Isolation CW=ars 1 'Ibe SBWR isolation condensers are represented in PANDA by a single c%=ar unit, similar in ) design to the PANDA PCC units. The PANDA IC is scaled 1:25 to the capacity of two of the three SBWR units. It has 20 tubes of full height and diameter with pmtotypical spacmg. Side plates guide the secondary flow outside the tubes to make it similar to the secondary side behavior of the SBWR units. The PANDA IC unit receives steam or steam / air mixture from the simulated RPV and returns ~ j condensate to the same vessel. Small vent lines can discharge non-condensable gas from the upper and lower headers of the IC to WW1. 3.3.8 Top LOCA vents 3 The SBWR LOCA vents are represented in PANDA by two 100 mm diameter pipes, one from each drywell to the suppression pool of the corresponding wetwell tank. The drywell end of the vera is 1 connected at the wall of the drywell vessel, near the bottom. The pipe enters the side of the wetwell tank, near the top of the gas space, and then tums 90-degrees downward and ends below the surface of the suppression pool. The flow resistance in the LOCA vents is not scaled for pressure drop as was done for other system piping. The pipe diameter is smaller than the " scaled" diameter (greater flow resistance) but is not a concern because there should be little or no flow through the SBWR LOCA vents at I hour after a scram. The suppression pool end of this pipe is submerged to a depth e equivalent to the top of the uppermost LOCA vent. i 3.3.9 Vacuum Breaker i The three SBWR drywell-wetwell vacuum breakers are mounted in the diaphragm floor which sepw the upper drywell from the wetwell gas space. This flow path is simnheed in the PANDA facility by a pipe from near the bottom of the each drywell to near the top of the corresponding i wetwell. The vacuum breaker valve itselfis simulated by control valves in each of these pipes. The i valve controllers are programmable so that the differential pressure required for opening and l closing can be controlled. A simulated wetwell/drywell leakage path is provided by a bypass line with a valve around each of the two simulated vacuum breaker valves. Effective bypass leakage areas can be varied by changing the size of an orifice in the bypass line and the bypass flow measurement system. i L 3.3.10 Other System Piping The PANDA piping which simulates the significant SBWR piping has been scaled to provide prototypical pressure losses for the scaled PANDA flow rates. The scahng ha been generally based on the SBWR design as it was in December 1992. The following piping has been scaled: l PCC Condenser Piping. Each of the three PCC Condenser units has an inlet line, a conden-sate drain line,and a vent line. Isolation Condenser Piping. The Isolation Condenser unit has a steam inlet line, a conden-sate return line, and a line for venting non-condensable gas from both the upper and lower l headers. l

l i ALPHA-410-l' Seite 12 f GDCS Lines to RPV. A pipe is provided to drain water from the GDCS Pool tank to the simulated RPV. i Main Steam Line. Piping is provided to cany steam fmm the RPV to the drywell, representing six SBWR*depressurization valves (DPV) or one broken SBWR main steam line and five DPVs. Equalizer Line. Piping representing the SBWR equalizing line has been provided between [ the bottom of the wetwells and the simulated RPV. i Auxihary Lines 'Ihe primary purpose for these lines is to supply tewWwo-controlled [ steam, water, and air to vessels and tanks in order to achieve the proper initial conditions. j Under certam circumstances, specified in the test procedures, these lines may be incorpo-rated into the actual tests. 4 3.4 Steady State Test Configuration 3 1he steady state PCC tests will be run with a different hardware configuration than that to be used for the transient tests. As shown in Figure 3-4 and Figure 5-5, a pipe will be installed to deliver steam directly from the RPV to PCC3 Air can be injected into this line downstream of the steam flow measurement location. The drywell tanks play no part in these tests, so they are isolated. The pressure in the GDCS tank and the wetwell tanks are equalized through an auxihary steam line. The PCC3 drain line will be open to the GDCS tank and the GDCS tank drain line will be open to the l RPV. The check valve in the GDCS tank drain line is removed. The PCC3 vent line to the wetwell (WW2) is not submerged in water in order to better control the pressure at the PCC3 upper header. For all tests (S1 through S9) the PCC3 steam supply line is insulated as shown in Figure 3-4. For the tests S7 through S9 the upper and the lower drum of the PCC3 unit will partially be insulated. The insulation covers 70% of the cylindrical part of the drum circumference. The region i where the ce=da=m tubes are welded to the dmm is not insulated. Figure 3-5 shows the details for the insulation of the upper drum. The lower drum is insulated in the same manner. For the tests S7 through S9 the section of the condenser vent line which is submerged in the PCC pool will be insulated by two Imm thick layers of Polytetrafluorethylen, wrapped around the pipe. In Table 3.1 the tolerances on the key facility characteristics for the PANDA Steady-State PCC 3 Performance Tests are listed. i

4. TEST FACILITY CONTROL AND SAFETY CONSIDERATIONS l

4.1 Control System Description In order to perform the steady state PCCS condenser performance tests, several control loops are to be used. nese control loops will be used to manage and regulate :he key test parameters. A main control system which includes the electronic controllers will be used to perform the operations. 4.1.1 Steam Flowrate Control The control of the steam mass flow-rate to the PCC3 condenser is performed by the operator by varying the electrical power to the heaters in the RPV. The operator will adjust the power as needed to achieve the desired mass flow rate based on the measured mass flow rate determined from a vortex volumetric flow meter together with the temperature and pressure in the steam line near the vortex flow meter. 4.1.2 Air Flowrate Control The control of the air flow-rate to the PCC3 condenser is performed using a digital electronic controller to which are connected the air mass flow measurement (hot-film flow meter) as the process variable and a pneumatic valve, inserted in the air supply line, as the actuator. 4.1.3 Pressure Control The pressure at the inlet to the PCC3 condenser is indirectly established by controlling the wetwell (WW2) pressure using the vent system. If the PCC3 inlet pressure is lovi, it is possible to add air to the wetwell for those tests with pure steam flow. For these tests the auxiliary air supply system is available, because it is not being used to supply air flow to PCC3. With the wetwell temperatures at approximately saturation temperature, however, it is expected that air addition to the wetwell will not be necessary to maintain pressure. 4.1.4 PCC Pool Level Control The PCC pool level will be monitored based on a differential pressure measurement of the head of water in the PCC pool. The test operator will maintain the collapsed pool level within the range specified for each test by adding or draining water from the PCC pool using the auxiliary water supply system. 4.1.5 RPV Water Level Control The RPV water level will be monitored based on differential pressure measurements along the vertical length of the RPV. Once the water level in the RPV is established prior to the test, the level should remain within the range specified for each test without any draining or adding of water to the RPV during the test, because the test duration is short and the condensate drain flow to the RPV

5. INSTRUMENTATION 5.1. General Requirements The test facility shall have sufficient instrumentation to measure all parameters needed to achieve the test objectives defined in Section 2. All test instrumentation shall be provided by PSI and shall be calibrated as necessary against traceable standards, i.e. the U.S. National Institute of Standards and Technology or equivalent.

The following Sections 5.2,5.3,5.4 and 5.5 cover all the currently planned instrumentation which will be used at PANDA (i.e. for steady-state and for transient tests). Section 5.6 describes the specific instrumentation requirements for the steady-state tests. 1 5.2 Instrumentation Identification System The identification system for the PANDA instrumentation employs the PANDA identification code. This is composed of three strings, which are separated by a point. < type >. < designation >. < extension > 4 < type > addresses the function of an identified item, < designation > refers to its location, which is expressed in terms of vessel or pipework designations (cf. Table 5.2), and < extension > is typically a counter, which allows items with otherwise identical type and designation to be distinguished. The syntax is: CAA fAA.AA 2 where 'C' stands for a character, 'A' for an alphanumeric symbol; underlined positions are mandatory. Hence, an identification code has a minimum length of four symbols and a maximum length of ten. Based on this identification code, PANDA measuring instruments are identified by a < type > with 'M' or T in the first (mandatory character) position. 'M'is used for instruments with electronically recontable output and T is used for instruments with only local visual indication of measurement. For measured data from one instrument or data which is calculated primarily from one instrument, the same identification is used as for the corresponding instrument. For measured data, which is calculated (derived) from more than one direct measurements, an additional < type > with 'D' in the first position is used if no single instmment is the primary measurement. For a measurement identification the second symbol in the < type > string is also mandatory and specifies the measured quantity, e.g. T stands for temperature, 'P' for pressure, etc. However, this information symbol moves to third position when the symbol 'S' is put in the second position, specifying that the measured quantity (typically flow) is being integrated over time. Elsewhere the third position is used to further specify the measured quantity, e.g. partial pressures or different types of temperature measurements. i

4 ALPHA-410-1 seite 22 I 5.3 Instrumentation Description i "Ihe PANDA test facility has the capability to measure the following physical parameters: .i temperatures, mass flow rates, pressures, differential pressures, liquid levels, gas concentrations, 2 and electrical power. PSI document [2] defines the ranges expected for the various parameters to be i measured. Table 5.3 provides a list of all the instrumentation available on the PANDA facility - together with the key charactenstics of each instrument including, in addition to the system instrumentation, the instrumentation of the auxdary systems. Figures 5.1 through 5.4 together with Table 5.3, show the general locations of all the instrumentation. Table 5.4 gives a summary listing of the total number of sensors of each type. The following provides an overview of the measurement capability in the facility. S 53.1 Temperature Most temperature measurements in the PANDA facility will be made with Inconel-sheathed Type K (Chromel Alumel) thermocouples. The reference junction temperatures will be measured with l thermistors. There will be capability to measure the following fluid temperatures with Type K therrnocouples: in the gas and liquid regions of vessels,i.e. RPV drywells and connecting line between drywells j i l - wetwells and two connecting lines between wetwells - GDCS pool in the liquid regions ofIC/PCC pool t liquid surfaces temperature in DW's, WW's and GDCS pool in the system lines,i.e. i - lines from the RPV to the drywell and the IC - lines from the drywell to the PCCs 1 - LOCA vent lines PCC ventlines l - IC, PCC and GDCS drain lines - vacuum breaker lines between the drywells and wetwells - wetwell/RPVequainationlines 1 - in the upper and lower headers of the IC and the PCC units 4 - inside some of the tubes in all four condensers. d In addition metal temperature measurements will be taken with Type K thermocouples: along the length of some of the IC and PCC condenser tube walls on the walls of key vessels and system lines. Platinum resistance (Pt100) temperature measuring devices with Contrans T TEU 421 amplifiers manufactured by Hartmann & Braun will be used to measure the fluid temperature at all flow rate measurement locations. 2

t i ALPHA-410-1 Seite 23 5.3.2 Flowrate t Flow rates in PANDA will be measured with four different types of flow measurmg devices. Three ultrasonic flow meters (System 990 Uniflow model manufactured by COhTROLOTRON) can be used to measure the volumetric flow rate at any three of the following locatens: - the PCC drain lines to the GDCS - the GDCS drain line to the RPV - the IC drain line to the RPV - the equalization line between the RPV and suppression pool. Ten vortex flow meters (Vortex PhD-90S model manufactured by EMCO) are set up in PANDA to measure the volumetric flow rate at the following locations: - the main steam lines - the IC and PCC supply lines - the PCC vent lines - the water supply line to the RPV or to the water auxiliary system A small vortex flow meter (Swingwirl II model manufactured by Endress & Hauser) will be used to measure the flaw in one vacuum breaker bypass leakage line. A hot-film flow measuring device (Sensyflow VT2 model manufactured by SENSYCON) will be used to measure the air mass flow supplied to the PANDA facility by the auxiliary air system. 5.3.3 Pressure Pressures throughout the PANDA facility will be measured with Rosemount model 3051CA, 2088A, and 1144A pressure transducers. The facility has the capability to measure pressure at the following locations: - in the RPV -in the drywell vessels - in the wetwell vessels (gas space) - in the IC and PCC upper headers (at the inlet flow measurement location) - in the GDCS tank - the atmospheric pressure - at all steam / gas flow measurement locations. 5.3.4 Differential pressure Differential pressures throughout the PANDA facility will be measured with Rosemount model 3051CD and 1151DP transducers. Capability exists to measure the pressure differences:

~ j ALPHA-410-1 T-l Seite 24 1 - between the gas spaces of the major vessels,i.e. -l RPV to DW1 along MSI i-RPV to DW2 along MS2 D W 1to W W 1 d - DW2 to WW2 i - along the length of key lines,i.e. 1 l PCC inlet, vent and drain lines IC inlet and drainlines i - GDCS drain line WWI and WW2 to RPV equalizationline j -- between upper and lower headers of the IC and PCC condenser units. 4 5.3.5 Waterlevel Water levels will be determined at several location in the facility by differential pressure measurernents with Rosemount model 3051CD and 1151DP pressure transducers. The capability exists to measure the actual water levels in these vessels: i ' ~ both drywell vessels both wetwell vessels the GDCS tank. The equivalent " collapsed" liquid levels can be measured in locations which may have gas (steam i or air) below the water surface. These are: in the RPV (total and 5 subsections) in each of the four compartments of the IC/PCC pool tank. i Capability also exists to measure the liquid level in the following lines: I the LOCA ventlines I l. the vent lines for the PCC condenser units. 5.3.6 Fluid Phase Indicator Eight conductivity probes will be used to determme whether the fluid phase is liquid or gas at the probe location. The probes are located: - near the bottom (exit) of the LOCA vent lines from the DW to the WW - at the inlet and outlet of the vent lines for each of the three PCC condensers. 5.3.7 Gas concentration / humidity Two oxygen analyzers which have the capability to determine the oxygen partial pressure can be [ mounted at three locations in each drywell and at two locations in each wetwell. The oxygen - analyzer can be used to determine the concentration (mass-fraction) of non-condensable gas at saturated and superheated conditions. i

L 5.3.8 Miscellaneous l p Wattmeters will be used to measure the electrical power to the RPV heatets. 5.4 Instrument Calibration 4 5.4.1 Temperature Measurements s i Inconel-sheathed Type K (Chromel-Alumel) thermocouples will be used for nearly all temperature measurements in the PANDA test facility. Approximately one-third of these thermocouples will be i l calibrated individually prior to installation in the facility using the thermocouple calibration procedure and hardware described in PSI report [3]. Platinum resistance temp-me measuring . devices (RTDs) are used for the reference calibration temperature. These platinum RTDs are i calibrated in Bem at Eidgen6ssisches Amt fiir Messwesen (Swiss Federal Office of Metrology). . Table 5.6 shows that all the thermocouples to be used in PANDA will be made from a few rolls or batches of bulk thermocouple cable purchased mainly from Philips (a commercial supplier). PSI checks each batch of thermocouple wire, upon receipt from the manufacturer, to confirm the wire 4 meets the rnanufacturers specification. This check is done by calibrating thermocouples made from each end of the batch or roll, over a temperature range of 50 C to 600'C. 1 j In addition to the check of the thermocouple matenal when received from the manufacturer, as i j stated above, approximately one-third of the thermocouples to be used in PANDA will be calibrated individually using the (3] procedure. Table 5.6 shows the number of thermocouples to be calibrated and the total number of thermocouples to be used from each batch. The individual i calibration will be based on approximately 30 calibration points spread uniformly over the temperature range from 50 C to 200 C. The results of these individual thermocouple calibrations l-will be combined for the thermocouples from each batch and statistically analyzed. The large j sample individually calibrated from a batch provides confidence that the roll calibration is applicable to those thermocouples which have not been individually calibrated. From the analysis a look-up table or a constant or first order (linear) correction to the standard calibration for this thermocouple material will be determined for each batch. The look-up table or correction to the j standard for each batch will be used to determine the temperatures for all thermocouples in each of i the batches. The results of the analysis of the individual calibration data compared with the roll i J calibration will be used to show that the thermocouple accuracy requirement of i1.5'C for the 1 temperature measurements is fulfilled. f No recalibration of the thermocouples is planned, because most of the thermocouples would be destroyed when removed fL,m the facility. On the other hand the temperature ranges for the thermocouples are sufficiently low to not influence the thermocouple characteristics and the i h6d K Type thermocouples have a very good long term stability. It should also be noted that j l there is substantial r+ad=cy in the temperature measurements, so it will be apparent if a thermocouple readmg is significantly in error. 1 } A sample of six (approximately one-third) of the Pt100 resistance temperature measuring devices to be used to measure fluid temperatures at flow measurement locations will be calibrated by a Swiss 1 Calibration Service Laboratory (Calibration Laboratory accredited by the Swiss Confederation l i

i ALPHA-410-1 i ' Seite -26 e represented by the Eidgen6ssisches Amt fur Messwesen at Bern).'A sample calibration of these Pt100 sensors is sufficient due to the following reasons: 2 a) the combined most probable error for the sensor, the amplifier, and DAS of 0.4*C [10] is small compared to the required accuracy (1.5'C), i b) the six calibration results show that the standard error is less than that given by the manufacturer, + 1 c) in the PANDA facility there is much redundancy for temperature measurements, therefore the noncalibrated Pt100 temperature measurements can be compared with other temperature 1 measurements during homogenous temperature conditions to confirm the manufacturer's calibration of these temperature sensors. s i 5.4.2 Flow Rate Measurements Each ultrasonic and vortex volumetric flow rate meter will be individually calibrated in Bern at the j Eidgenoessisches Amt fuer Messwesen prior to installation in the PANDA test facility. A linear fit to the calibration data for each volumetric flow meter will be determmed and used for reduction of l the flow meter data. For one flow meter of each size and type, ten to thirteen calibration points will j be ahtai=A covering the full range of expected flow rates with emphasis on low flow conditions. If these calibratice data show the flow meter calibration is imear over the flow range calibrated, then j the calibration of other flow meters of this size and type will be done with fewer calibration points (at least six). i i The hot-film flow meter to be used for measurement of mass flow rates for air added to the facility with the auxihary air system will be calibrated by the manufacturer, a German Calibration Service { Iaboratory (an accredited calibration laboratory). 1 The flow rate meters will be recalibrated after two years, i.e. in early 96, or earlier if there is an apparent error in a flow rate measurement or the test flow rates are exceedmg the calibration range. 4 Any significant change in calibration" for a flow meter will be identified as a non-conformance per PQAP-NC and considered in reporting and reduction of the flow rate data for that flow meter. I 5.4.3 Pressure and Differential Pressure Measurements All pressure and differential pressure sensors to be used in PANDA are manufactured by Rosemount Inc. All these sensors will be calibrated by PSI prior to installation in the facility according to the procedure defined in [4], except for the Model 2088 and SMART Rosemount l pressure sensors. For the Model 2088 and SMART sensors the calibration data obtamed at the Rosemount factory will be used. The device used to generate and rneasure the reference pressure for the PSI calibration of all other i pressure sensors is a Baratron System 170 manufactured by MKS Instruments, Inc. The reference is calibrated in Bern at Eidgenoessisches Amt fuer Messwesen. i 1 A significant change in calibration is defined as a change which would result in the sensor not meeting the accuracy requirement specified in Table 5.3.

ALPHA-410-1 Seite 27 The pressure and differential pressure sensors will be recalibrated after two years, i.e. in early 96. Any significant changes in calibration

  • will be identified as a non-conforrnance per PQAP-NC and considered in the reduction and reporting of data for the specific sensor with the change in calibration.

Approximately 10 calibration points will be recorded for each sensor covering the range of pressures or differential pressures expected from [2]. A linehr fit to the calibration points for each sensor will be determined using the least squares method. The residual for the calibration points reladve to the linear fit will be determined for each sensor. The residual will be used to establish whether or not each sensor meets its accuracy requirement. 5.4.4 Oxygen Partial Pressure Measurernents The oxygen partial pressure will be measured at some locations in the PANDA facility in order to infer the air partial pressure and humidity. The voltage output of the sensor to be used to sneasure the o.ygen partial pressure is a function of the sensor temperature and the differential oxygen pressure across the element. [5] desenbes an evaluation of the feasibility of using this sensor to determine the air partial pressure and humidity in the PANDA tests. It is not====y to calibrate this instrument based on the evaluation in [5]. 5.4.5 Conductivity Probe ~ Conductivity probes will be used to establish whether the fluid phase at the probe location is liquid or gas. Prior to a series of tests in which the conductivity probe measurements are required, the water level near the probe will be varied so that the probe is exposed to only gas and then to only water. The output of the probe wid be monitored and recorded at the Data Acquisition System (DAS) while the fluid phase the probe is exposed to is changed. This will be done to confirm that the probe can detect whether it is exposed to gas or water. 5.4.6 PowerMeasurement The 115 electrical heater rods of the RPV, with a maximum capacity of 1.5 MW, are divided in 6 groups. Four groups with 23 heater rods in each group are on/off controlled and two groups with 4 and 19 heater rods, respectively, have a continuous power control. Four Sineax PQ502 Wattmeters are used for measuring the heater power of the four on/off groups. The power of the two controlled groups is measured by Sineax 6P1 Wattmeters. All six Wattmeters will be calibrated by an accredited Swiss Calibration Service Laboratory (cf. Section 5.4.1). In addition, the total power of the RPV heaters is generated using an electrical summmg of the six measured group powers. A significant change in calibration is defined as a change which would result in the sensor not meeting the accuracy requirement specified in Table 5.3.

5. 5 Error Evaluation The most probable error for directly measured quantities (thermocouples, resistance temperature detectors, and core power) are calculated using the following:

2 + g, + oj (5.1) 2 o =0 where o, is the instrument accuracy, og is the error associated with the analog to digital converter, and, in the case of thermocouples, aq is the error associated with the reference junction temperature measurement. The upper bound error is then calculated in a similar fashion: om =lol+logl+lodl (5.2) f The instrument accuracy for the thermocouple wire is based upon manufacturer specifications and calibrations performed at PSI. Accuracies of the other instmments are based upon manufacturer specifications or calibrations performed at the Swiss equivalent of the National Bureau of Standards The upper bound and most probable errors in the flow rates, absolute and differential pressures, water levels, air partial pressures, and condenser efficiencies are calculated from the relations detailed in Section 7 along with an error propagation formula. The most probable error in the quantity u is calculated from the following: N r 32 r={X> 2 g, (5.3) o t=1 4 I where the xi represent the measured quantities comprising u. The upper bound error takes a similar form: A a l 0,, l (5.4) o= The " accuracy" values for most of the instruments listed in Table 5.3 are based on calculations of the most probable errors using Equation 5.1 or 5.3. The detailed error analysis is summarized in [10]. 5.6 Required Measurements For Tests S1 through S9 The steady state test configuration and the required instrumentation is summarized in Figure 5.5. Table 5.5 gives the measurements required to meet the objectives for Tests Si through S9. Temperature measurements in PCC3 are desirable, but not all of these temperature measurements are required for the performance of these tests. No PAhTA instrumentation other than that in Table 5.5 is necessary for the performance of Tests Si through S9. All the sensors listed in Table 5.5 must be operable when these tests are run, except for the PCC3 temperature measurements. For

~_ - ALPHA-410-1 Seite 29 the PCC3 temperature measurements, all that are required are the PCC3 inlet and outlet temperatures and a representative sample of the other temperatures as determined by the test engineer at the time of the test. It is desirable, but not required, that at least two tests with the lower air flow rates, i.e. less than 0.01 kg/s, have enough PCC3 temperature readings to allow detailed evaluation of the heat transfer. 1 e t } d I i I i. ,,.w

6. DATA ACQUISITION SYSTEM AND RECORDING i

The data acquisition system (DAS) for PANDA is an integrated system which measures signals and converts them to engineering units and records the data. 6.1 Hardware configuration The data acquisition system consists of components completely integrated in order to enable the user to perform all the significant actions connected with the data acquisition process. Figure 6-1 gives a schemt. tic of the PANDA data acquisition and control system. The DAS is made up of a HP 3852 main frame plus four HP 3853 extenders. The rnain frame and each extender contain a HP 4470416 bit high speed voltmeter and several HP 44713 24 channel multiplexers in which 24 PSI produced preamplifier / active filter units are integrated. The number of multiplexers. depends on the extender. The sensor cables are connected to the terminal module of a multiplexer and the signals are then amplified and filtered in the PSI produced unit. The gain of the preamplifiers is 40 and the active filter is a second order low pass Butterworth function filter set to 18 Hz. This setting is low enough to eliminate 50 Hz signals which might be introduced through power supplies, and high enough not to filter out any data from the 0.5 Hz scan rate of the DAS. The amplified and filtered signal then is fed into one of the multiplexers. The main frame and the four extenders are located on five different levels of the PANDA facility. The main frame is located at a height of 2 meters. The extenders are located at heights of 6 m,10 m,14 m, and 18 m. This reduces the amount of cabling required and minimizes electrical noise due to long cables. There are a total of 30 multiplexers spread over the five different levels. The multiplexed analog signals are read by the high speed voltmeters which are located on each level. The voltmeters have a 320 mV range and the output is digital data. The system operates in a continuous scan mode. Readings that are not requested are discarded. The channel list is stored in the digital voltmeters. The 720 channels may be scanned at a manmum rate of once every 2 seconds. The scan rate must be manually set in the software. Parallel measurements are made in the main frame and all four extenders. The data is stored in the digital voltmeter, and then transferred over a digital connection to an output buffer in the HP3852 mainframe. The mainframe then sends a service request call to a HP-1000A990, which processes the data acquisition program and controls the data storage. The HP-1000A990 detects the service request call, reads the data and sends the data to the conversion program. The conversion program converts the binary digital signal into engineering units and then distributes the data to disk storage, to a printer (when requested), and to a HP workstation for further data storage and/or transfer to a process visualization progmm on a IBM compatible PC.

ALPHA-410-1 Seite - 65 v 6.2 Software qualification The data acquisition system software will be qualified by performing the following actions:

1) check that the instrument conversion constants are correctly input and allocated in the DAS i
2) check that the conversion formulas are correctly inserted in the DAS
3) send calibrated voltage signals to the DAS input channels (simulation of the sensor 4

signals) and verify that: l - the wiring (sensor to termmal module to preamplifier / filter to multiplexer)is correct. ] - the voltage readingis correct. - the conversion to engmeenng units is correctly applied (by comparing the DAS conversion results with the same signal conversion carried out by hand calculations). These verifications will be performed once for both ducetly measured quantides and for derived quantities. The results of the verifications will be archived in the DRF. If an instrument is replaced, the verification for that instrument will be repeated. The instrument zeros will be verified for 1 cntical instruments before each series of tests. l 4 i t 4 5 9 d d 1

ALPHA-410-1 Seite 67 7. DATA ANALYSIS AND RECORDS This section describes the data analysis for both the steady-state (S Series) and transient (M-Series) tests in PANDA. 7.1 Data Reduction / Conversion to Engineering Units 7.1.1 Temperature Temperatures measurements used to calculate fluid and gas densities for mass flow measurements are made with Pt100 resistance temperature detectors. Each Pt100 output is converted by a power supply / amplifier to a linear 4-20 mA current output. which is in turn converted into a voltage for the PANDA data acquisition system by a 0.40 load resistor. The amplifiers are calibrated so that 4 and 20 mA correspond to 0 C and 200 C, respectively. The remaining temperatures are measured using K-type chromel-alumel thermocouples. Groups of 23 thermocouples are routed to isothermal blocks where the reference junction temperatures are measured by a thermistor. The thermistor voltage is converted to a tempenture using a look-up table in the data acquisition system. This temperature is then converted to a K-type thermocouple voltage using look-up tables generated according to National Institute of Standards and Technology (NIST) monographs (April 1993) for the Intemational Temperature Scale (ITS-90). The temperatures measured by the thermocouples are determined by adding the K-type voltage of the thermistor to the measured thermocouple voltage. This sum is converted to a thermocouple temperature using a third set of look-up tables taken from the same source of monographs. After this standard conversion, individual corrections are applied as described in Section 5.5.1 on thermocouple calibrations. 7.1.2 Absolute Pressure Absolute pressure transmitters provide a current output that is converted to a voltage by a 0.4Q load resistor dedicated to each channel, and this voltage is measured by the data acquisition system. The measured voltage V is converted to an absolute pressure using the following relation: P = V

  • a + b - pgh (7.1) where the constants a and b have been determined through instrument calibration as described in

[4). The final term accounts for the hydrostatic head of the water column (of height h) isolating the j transmitter from the hot atmosphere within the PANDA vessels. The density p, calculated in most i cases at 20 C,is considered constant. 1

? i I i ALPHA-4101 Seite 68 7.13 Differential Pressure Output from each differential pressure transmitter is measured by the data acquisition system in the same manner as described for the absolute pressure transmitters. The measured voltage is converted to a differential pressure using the following: l AP = V

  • a + b - pgd (7.2) where the terms a and b are agam the calibration constants and the calibration procedure is detailed in [4]. The final term accounts for the difference between the hydrostatic heads of the reference leg water columns. This is calculated by multiplying the difference between the two pressure tap

~ elevations, d, by the water column density p and the gravitational acceleration g. ) . For some differential pressure measurements (i.e. along the IC/PCC vent lines) one pressure leg is gas filled. For these cases the hydrostatic heads of the gas reference column must also be taken into account. The conversion to differential pressure is therefore sligthly modified: 4 l AP = V

  • a +b-g (pd + p, L)

(73) i where p, is the gas density in the gas reference leg and L is the vertical height of the gas leg. 7.1.4 Level l The single phase or two phase (collapsed) water levels for closed vessels are calculated from measurements of differential pressure. Using the differential pressure as calculated in egn. 7.2, the following relation provides the collapsed water level between the two pressure taps: L = AP + p,g

  • d (7.4) g *(p, - p,)

b The gas density p, is included to account for the head generated by the gas layer above the water surface, and d is again the vertical distance between the two pressure taps. The gas layers in the RPV, drywells, and GDCS are assume.1 to be pure steam while gas layers in the wetwells are assumed to be pure air. The air density is calculated from the perfect gas law using ter+Eum and absolute pressure measurements of the wetwell gas space. For the open IC/PCC-Pools the differential pressure measurements used for calculating the pool levels are gage pressure measurements. Using the differential pressure as calculated in egn. 7.2, the i following, slightly modified, relation provides the pool level: L = AP + g p,d (7.5) g (p, - p,) l where p,is the ambient air density. L i

i ALPHA-410-1 Seite 69 t I 7.1.5 Flowrate Gas flowrates are determined with vortex flow meters, which are calibrated in terms of volumetric j flow.The calibration curves have the following form: 9'= V *a + b (7.6) l I Mass flow rates are then calculated from the measured volumetric flow, absolute pressure, and gas temperature: m=9* p, + M P=~ 9tT - .(7.7) where 9t is the gas constant and M is the molecular weight of air. The vapor density p, is set equal to the saturation density at the measured gas temperature T. The noncondensable partial pressure P. is the difference between the absolute pressure P, and the vapor partial pressure at the saturation temperature T. Liquid flowrates are rneasured with ultrasonic flow rneters. Like the vortex flow meters, these 1~ instruments are calibrated in terms of volumetric flow, and the calibration curve takes the same form as that given in eqn. 7.6. The calibration is valid only for single phase flow and so the mass flow rate is simply: m = 9

  • p, (7,g) where the liquid density is calculated using the Pt100 temperature measurement located downstream of the flow meter.

A hot film flow meter measures air flow from the auxdiary air system into PANDA. The meter generates a 4-20 mA output that is proportional to the mass flow rate and has been calibrated in ) Germany in conformance with standards issued by the German equivaient of the National Bureau of Standards. I ) 7.1.6 Oxygen Sensors The noncondeauhle gas partial pressure is measured in selected locations using zirconia oxygen sensors. The sensor generates a voltage dependent upon the ratio of the oxygen partial pressures on i the measurement and reference sides of the zirconia element [5]. This voltage, measured directly by the data acquisition system, is used with the following equation to calculate the noncondensable pressure: P = Pe e" (7.9) where T is the measured sensor head teirpeuic, and C is a constant equal to 0.02154 mV/ K. Air i . at atmospheric pressure is used as the reference gas and so P is the measured barometric pressure. { 3 l

l f f i ALPHA-410-1 Seite 70 l 7.1.7 Phase Indicator l 1 Electrical conductivity sensors are used to detect the presence or absence of liquid at the vent line inlet and outlets, and at the bottom of the LOCA vent lines. When the probe tip is imroersed in liquid, an electric circuit is completed, the other way around, when the probe tip is surrounded by i gas, the circuit is open. The conversion to engineenng units produces from this a real value of 1.0 and 0.0 for gas and liquid, respectively. 7.1.8 Power Measurement i The power of the electrical heaters in the RPV is measured by a wattmeter (3 phase, arbitrary j waveform) which provide a current output that is converted to a voltage by a 0.4 O load resistor. The measured voltage V is converted to an electrical power using the following relation: N = V *a + b G.10) I where the constants a and b are based on the ordered configuration for the wattmeters. 2 i 7.1.9 Condensor Energy Balance i The power transferred to the condenser water pool is written as products of specific enthalpy and j mass flow rate at the condenser inlet, exit (vent), and drain (description of symbols see Table 7.1) Q=sh-4,h,-s,h, G.11) It is advantageous to elimia* either the vent or condensare flow measurement from the energy balance. The energy balance can then be formulated in two different ways; the first is written by writing the vent mass flow rate in terms of the drain and inlet mass flow rates. The inlet air and steam flow rates are measured separately before rmxmg and so the energy balance is written as: l Q = (4,h, + s,h,)l,- (s, + s, }l,-s, h, - 4,h, G.12) Now the above expression is written in terms of measured quantities. The inlet air mass flow rate is measured directly while the inlet steam mass flow rate is calcdated from a volumetric flow rate measurement and the steam density. The condensate mass flow rate is also derived from a i volumetric flow rate measurement and so the energy balance rs now. i Q = (9,p, h, + s,h,), - (9,p,+s,),-9,p, (x,h, + x,h,)l, - 9,p,h, G.13) where9is the nasured volumetric flow rate. Enthalpies and densities are calculated from temperidure measurernents and steam tables. The steam and air mass fractions (x, and x,) are calculated from their respective densities at the vent. The former is taken from a steam table and the latter is calculated by subtracting the vapor partial pressure from the total pressure and using the perfect gas law. It is assumed that the air and vapor velocities in the vent are equal. The second energy balance, which can be used as a check against the first, is formulated in terms of inlet and vent flow rates, which eliminates the drain flow rate measurement:

l c l ALPHA-410-1 j Seite 71 l 1 ~ Q = (s,h, + s,h,)l,-(4,h, + s,h,)l, - (s, + s,)l, -(s, + s,)l, h, (7.14) i i The condensor energy balance in terms of measured quantities is now written as: i 1 t

  • ~

' (h4 - h,) 9 (7.15) G = 9,p,(h, - h,) + s,(h4 - h,)], - p,(14. - h,) + j a j where M, and 9t are the molecular weight of air and universal gas constant, respectively. As indicated, all quantities in the first and second terms are evaluated at the inlet and exit conditions, respectively, except the drain enthalpy, which is evaluated at the measured condensate temperature. If the condensor reaches a true steady state, the inlet air flow rate is identical to the exit air flow rate. Thus equation 7.13 can be simplified to: G =,,P, (h,, - h,,) + 4 (h - h ) - 9,p,(h, -h,,) - (7.16) 4 4 4 and equation. 7.15 can be simplified to: l O = 0,,P, (h,, - h,) + s,(h - h ) - 9,p,,(h,, -h,) (7.17) a 4 4 Energy balance accuraces will depend on the drain and vent flow values. For most cases, where the air fraction is low, egn. 7.16 will be more accurate than eqn. 7.17. Equation 7.16 will be used to t calculate the PCC condenser heat transfer in the steady state tests because of the relatively high drain flow fraction. Equation 7.17 will be used to confirm the results. l i Each of the above measured quantities is described in the Table 7.1. Also given are the process identifications for each flow and temperature measurement used in the energy balance. The process identification for temperatures used to calculate enthalpies and steam partial pressures are also listed. Note that the energy balance will not be calculated on line with the DAS software, i.e., ] during the experunent, but rather during data processing and analysis (cf. Section 7.2). J h 7.2 Data Processing and Analysis l 7.2.1 Pretest Durmg the preconditioning of the test facility the operators will monitor the required instrumentation identified for these tests in Table 5.4. 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. 7.2.2 Post-test / Quick Look After each test, a quick look at the data will be performed in order to provide the information t necessary to proceed with the next test. This quick look will b: focused on identification of

This quick look will include a cursory review of time history plots covering the full test j l duration for all of the required instmments. i 7.2.3 Post-test / Apparent Test Results Report Inputs I j Following completion of the tests described in Section 9, data reduction will be performed to i j support preparation of the Apparent Test Results Reports (ATR). This data reduction will include time history plots of all the required measurements covering the full test duration. In addition l digital data tables for the key parameters will be prepared with averages and standard deviations of l these key parameters over the test duration. These results will be reviewed and reported in the - ATR. i 7.2.4 Post-test /DataTransmittalReport i lhe Data Transmittal Repost (DTR) will transmit all the data for the steady state tests. It will provide detailed information on the test facility configuration, test instrumentation, test conditions and the format for the data. In addition, samples of key data will be presented in tables and plots. 7.3 Data Records The digitally acquired data will be recorded in real time for the entire duration of the' test. f immediately after the test, a copy of the data file will be created on magnetic tape in order to have a t permanent record of the data file. Also to be recorded with this data file are all information required to perform subsequent processing of the data. 7.4 Data Sheets The following data sheets will be prepared for each test for inclusion in the Design Record File (DRF). The test identification code will be printed on each sheet.

1) print table containing the list of the measurements with their main characteristics (identification, i

span, calibration constants, associated error, location on the facility, measurement channel number and sampling frequency)

8. SHAKEDOWN TESTS Shakedown Tests were conducted accordly to Rev. O of this document. The following changes in the TP&P were made as a consequence of these Shakedown Tests:

Configuration: Check valve CK.GRT in the GDCS Drain Line removed Procedure e - RPV water level (ML.RP.1) reduced to E 3.0 m - GDCS temperature preconditioning to = 393K - Manual contml of Wetwell backpressure 'Ihe purposes of the shakedown tests are to: - confirm test facility stability (i.e. ability to reach a steady sta.e) - confirm adequacy of data acquisition system - confirm ability to control pressure and flow rates - confirm the adequacy of the test procedures for the steady state matrix tests. The tests will entail steady-state condensing of pure steam or steam / air mixtures in the PCC3 unit. The PANDA facility will be configured in the same manner as the steady state matnx tests, described in Section 3.4 and Section 9. The reference test numbers are from Section 9. The detailed test procedure with its check lists are contained in the PANDA Steady State Test Procedure (Part II of this document). 8.1 General description of test SD-01 (Reference Test S3) This first shakedown test is intended to test all systems to be used during the steam / air matrix tests described in Section 9. Steam from the RPV and air will be fed directly to PCC3 where the steam will be condensed. The pressure will be controlled from the wetwell tanks such that the pressure at the inlet to PCC3 will be 300 kPa. The pressure will be contmiled by the venting of air / steam from the wetwell tanks. The PCC pool water level will be maintamed at the normal water level. 8.2 General description of test SD-02 (Reference Test S6) This shakedown test is to be run to check out the facility for its pure steam test setup, i.e. with closed PCC3 vent line. Steam only will be fed directly from the RPV to PCC3 where it will be condensed. The steam flow rate (0.26 kg/s) will be approximately equal to the condensing capacity of the PANDA PCC at 3 bars. With a closed PCC3 vent line the condenser inlet pressure will float to match exactly the condensing capacity for the given flow.

9. TEST MATRIX 9.1 Test Description A series of steady state tests will be conducted using one of the PANDA PCC condensers. The facility will be configured as described in Section 3 to inject known flowrates of saturated steam and air directly to the PCC3 heat exchanger. The condenser inlet pressure will be maintained at 300 kPa for all tests with air flow by controlling the wetwell pressure. The pool surface elevation in WW2 will be low relative to the PCC3 vent line exit elevation. The steam and air flow to the heat exchanger will be controlled and measured. In addition, the condenser drain flow and vent flow will be measured. Four tests are planned with various air flows and a constant steam flow of 0.195 kg/sec. In addition, two tests with no air flow will be run. One with the same steam flow as for the steam / air tests and one with a steam flow equivalent to that expected to match the steam condensing espacity of the condenser at 3 bars. For these tests with no air flow, the PCC3 vent will be closed as described in Section 8.2. The test conditions and the corresponding tests in PANTHERS and GIRAFFE (Phase 1, Step 1) are:

Following Test S6, insulation will be added to the upper and lower headers to make the heat removal from the PCC tubes relative to the heat removal from the headers more representative of the SBWR (detailed description in Section 3.4 and Figure 3-5). Following addition of the insulation to the PCC3 headers, Tests S3, S5 and S6 will be repeated as tests S7 through S9 to determine the steady-state heat removal with the headers and vent line insulated. ) l ~ lt may not be possible for the PANDA air supply to deliver this flowrate. If this flowrate cannot be reached, the test will be done at the maumum air flowrate which can be reached. l

The PCC3 Upper Header Pressure is the attainable pressure for S1, S6 and S9. The PCC3 Pool Level for all tests (S1 through S9) has to be 24.3 m above PANDA facility reference elevation, or 4.5 m above bottom of PCC3 pool. Tests S2 through S5, S7 and S8 will be conducted with air injection directly into the PCC3 condenser inlet line downstream of the vortex flow meter used to measure the steam flow to the condenser. The air flowrate will be provided by the auxiliary air system and the air flowrate will be measured with a hot-film flow meter. 9.2 Acceptance Criteria In order to assure the objectives of these tests are met, it is necessary for:

1) all the required instmmentation defined in Section 5.6 and Table 5.5 to be operational, and
12) the mean values over the 10 minute test period for the following test con the specified ranges:

- PCC3 Upper Header Pressure = reference matnx valuei4 kPa - Steam Flow to PCC3 = reference matrix valuei5% - Air Flow to PCC3 = reference matrix valueiS% - PCC3 Pool Level = reference matrix valuei20 cm

3) the standard deviation about the mean over the 10 minute test period for the four test conditions listed above must be equal to or less than the specified tolerance in order to assure steady state conditions (see Section 9.3). For example, the standard deviation about the mean for the air or steam riow should be equal to or less than 5%:

1 ~ It may not be possible for the PANDA air supply to deliver this flowrate. tf this flewrate cannot be reached. the test will be done at the maximum air flowrate which can be reached.

ALPHA-410-1 Seite 77 9.3 Definition of Steady State Steady-state conditions are defined as conditions for which the mean values of all four parameters specified in Section 9.2 are within the ranges specified, and the standard deviation about the mean l for each of these four parameters is equal to or less than the tolerance specified in Section 9.2. These mean and standard deviation values should be within these ranges for the 10 minute test period for the test to be acceptable. On-line Steady-state Conditions Evaluation and Data Recording The test data should be recorded over a time period longer than the 10 minute test period. The data recording period should be selected by the test engineer to be long enough so that there is high confidence that a 10 minute period can be selected for post-test data reduction which will meet the criteria in Section 9.2. Test conditions conformance to the criteria will be rigorously evaluated during the post-test data reduction. The conditions will be evaluated on-line during the test performance by the test engmeer's review of time history plots of the four parameters hsted in Section 9.2, since the capabilities to do rigorous calculations of mean and standard deviation values on-line at PANDA do not exist at present. The test eagineer will do visual estimat~ of the mean from the time history plots of the parameters listed in Section 9.2 to determine if they are within the range specified. He 1 will also do visual estimates of the the magnitude of the oscillations of each of these parameters about their mean values. (See Figure 9.1 for example). By using the peak values to assess parameter oscillations it will be assured that the standard deviation is with its required range. When the visual evaluations based on the time history plots indicate that the criteria has been rnet for a period of approximately 5 minutes, the test data recording period will be initiated 1P l Average iachieved .n ., v. .y. jValue u lspecified <+/- 5 % ~ l<+/- 5 % l l oscillation about the average i irne l Fig. 9.1: On Line Steady-state Conditions Evaluation (Example)

? ALPHA-410-1 / Seite 82 - 00 Introduction The following Steady State Test Procedure describes all test phases, including the preconditioning processes. This procedure is applicable to all Steady State Tests with steam / air mixtures and pure steam given by the Test Matrix and has been evaluated and verified with the Shake Down Tests. Due to the increased condensation rate occuring with pure steam flow through the PCC3, the initial conditions must be modified; A description of the modifications in configuration and procedures is given in n*200. The initial conditions have been defined according to the ant %ated steady state, which determines all preconditioning and test sequences. A summary of the whole operation course is given in section 02. 4 01 Initial Conditions The PANDA configuration used for the Steady State Tests differs from that needed for the transient tests. The initial conditions are not defined for the whole facility, but only for the components included in this specific configuration. The test configuration includes the RPV, Wetwells, GDCS, i PCC3 and PCC3 pool. 1 The chosen initial conditions are based upon the fixed parameters desired for each experunent such as condenser inlet pressure and gas flow rate. These conditions may not exactly match the steady state that the facility will reach before measurements begin; they are only an estimation of that state under the desired test conditions. Therefore, it is not weary to exactly match the vessel initial conditions shown below. i Measurements begin only after the entire facility has reached a steady state, vessels are preconditioned to the anticipated steady state. Vesselinitial conditions are as follows: 01.1 Steam / Air Tests PCC3 Condenser (X.P3): condenser inlet pressure maintained at 300 kPa Reactor Pressure Vessel (V.RP): pressure equals to 300 kPa => T=Tsat=407K no air water level elevation at 2500 mm => ML.RP.1=3.0 m PCC3 Condenser Pool (V.U3): pressure equals atmospheric pressure P=Patms98 kPa => T=TsatE371K water level at elevation 24300 mm => ML.U3=4.5 m GDCS tank (V.GD): pressure at 300 kPa temperature at about the same as the condensate temperature T=393K => PsteamE200 kPa & Paira 100 kPa no water l

The preconditioning steps shown here (phase n'20 through n'71) can be deviated from as needed to achieve the initial conditions listed in phase n'01. It is not necessary to adhere strictly to these preconditioning steps or record the performance of these steps, because they will not affect the test results. The important phases which will affect the test results are listed in the Checklist in Attachment 1. These steps will be strictly followed. The schedule given in Table 1 shows an overview of all sequences,i.e. facility startup, preconditioning, test and end of test operation. Each phase is represented by a dart rectangle with the corresponding estimated duration written inside. i r-

ALPHA-410-1 l Seite 84 After the facility startup, the RPV is used as heat source for the preconditioning of the other vessels. Since water filling, steam and/or air injection are independent processes, several phases can be conducted simultaneously. The GDCS is heated by hot water filling while the gas is vented to atmosphere. After that process has been completed, the Suppression rhmhm structure is heated by steam injection. The PCC3 pool conditioning is performed by transferring water at -373K trom the GDCS to the pool. The initial conditions are then adjusted before test is conducted. After all PANDA c(-g-:--:sts are separately conditioned, the required test configuration is set before l adjusting steady state initial conditions and performing the test. 'Ihe total preconditioning duration would be about 10 hours if all phases were performed sequentially, but performmg some phases in parallel shortens the overall duration to about 8 hours. Some uncertainty in the total time necessary for preconditioning is due to the processes indicated by "xxx" symbols in Table 1. The duration of these phases is not accurately known at this stage. . Note: All' numbers given for start conditions (temperatures, pressures, levels etc) and elapse time calculations are based on the assumption, that preconditioning starts under the following conditions: - all vessels are drained from water and contain air at ambient pressure - facility temperatureis 283K [ - available power ist limited to 600 kW [ If different start conditions are found, the individual steps have to be appropriately modife' d f at the test engineer's ducction. i ) T l t i u.

ALPHA-410-1 Seite 86 10 Preparation - Establish Initial Configuration Before starting any preconditioning process, the facility is set into a specific state, which must allow facility operations from the PANDA WARTE (PANDA Control Room). The configuration must be set in order to avoid any hardware manipulation during test or preconditioning processes. Data Acquisition and Control Systems considered as tools to set up the facility must be properly tumed on. And as last preparation phase, the auxiliary water system is filled to allow pumps operation. The phase n*ll describes the start of the PANDA Software, while the valve setup is explained in the section n'12. The phase n'13 consists of the auxiliary water system filling. 11 Control System and DAS Setup - Ethernet connection is isolated from PSI network (Unplug ETHERNET connecter) - Run Factory Link Software on HP-UNIX workstation (cf. DAS and Control Syst. User's Guide) - Run DAS software (cf. DAS User's Guide) - Run Factory Link Software on PC (cf. Control Syst.

ALPHA-410-1 Seite 87 20 RPV Setup for Vessel Preconditioning As the heat source for the whole preconditioning process, the RPV must be capable of producing steam for vessel heatmg or providing hot water to the auxiliary water system. In order to establish conditions to generate steam, the RPV is first heated to 373K, while most of the air is purged by venting to the atmosphere. Not all air is purged at this temperature, but this does not affect the vessel preconditioning. Pure steam conditions are only required for the tests. Then the RPV is heated to about 400K to supply the auxilliary water system heat exchanger. The RPV water level must be higher than the riser (elevation 10500 mm) and lower than the main steam lines; it is set for the preconditioning phase to elevation 11000 mm. The water filling is described by the phase n'21 and the heating in the next phase n*22. During the phase n*22, the auxiliary steam system lines are connected to the RPV to avoid pressure difference. 21 Water Filling 21.0 Check RPV Parameters - Check waterlerd MLRP.150.00 m <=> M(RPVwater)=0.00 ton 4 Comment: - M(RPV-water) corresponds to the arnount of water contained in the RPV. 21.1 Supply water until level elevation equals 11000 mm i Open control valve CC.RPV MLRP.1=11.5 m => AM(water)=13.7 ton MV.

ALPHA-410-1 Seite 89 30 GDCS Setup As condensate tank and in order to measure the water flow rate in the retum line, the GDCS conditions require no water level and a pressure of 300 kPa. To maintain that pressure, the initial i temperature is chosen equal to that from the condensate coming from the PCC3,393K. Starting the GDCS preconditioning process from atma.pheric conditions, we first heat the tank to 373K by hot water filling, then in a second stage with steam to 393K and fmally pressurize the vessel by air injection. Heating the GDCS by hot water fdling assures homogeneous temperature; in l order to also fill the PCC3 drain line, the tank must be filled to a level higher than the condensate drain line outlet level, which is at elevation 17025 mm. The air is vented by water filling to the atmosphere. The second stage of preconditioning to 393K by steam and the pressunzation phase with air is performed after the PCC3 pool filling phase. The phase n'31 describes the Structure Heating (1) with hot water.

ALPHA-410-1 Seite 93 40 Suppression Chamber Setup The test conditions require to maintain a constant pressure during the test course at about the same as the condenser inlet pressure. In order to easily satisfy that condition, the temperature is defined to avoid condensation of the steam, which may be vented through the PCC3 vent line. Corresponding to saturated condition at the condenser inlet, the temperature is set at about 407K. Most of the air is purged to the atmosphere and the pressure is controlled by the vent control valve CC.SIV. Both vessels are simultaneously heated by steam injection.

Control System User's Guide) i s i 200 Pure Steam Tests For the Pure Steam Tests (S1, S6, S9) the Steady-State Tests acwyu-ce criteria as stated in sections 9.2 and 9.3 remain unchanged. However, the condenser inlet pressure is not pr@rmined but found as the principle result of tests which are conducted in accordance with the following test j procedure. To reach and maintain pure steam conditions in the condenser, the facility configuration, preconditioning and operation as described above for the Mixed Flow Tests must be modified. i l For the Pure Steam Tests the condenser inlet pressure is not controlled; instead, the inlet pressure will be found by having the system float to the pressure for which the condenser performance exactly matches the given steam flow (henceforth: equilibrium pressure). If, with the mixed flow configuration of the test facility maintained, in tte course of this floatin; process the condensing i capacity were not reached (i.e. approaching steady state from a higher than cquilibrium pressure) an undefined part of the condenser would be blanketed in some way, e.g. by air sucked back from WWs. To avoid such air contamination for the Pure Steam Tests the WWs are disconnected from the condenser, i.e. the condenser vent line is closed. 'Ihe remaming facility configuration is therefore a simple closed circuit: RPV 4 PCC3

  • GDCS -+ RPV However, to assure pure steam conditions the condenser is intermitteutly purged to the WW, where a slightly lower pressure is maintained than in the condenser header. Pure steam conditions are reached when, aRer purging the condenser to the WWs, the system recovers to the same pressure as before purging.

To have contml of the effective < condenser > - <WW> pressure difference (for venting) requires the WWs to be preconditioned, similarly as for the Mixed Flow Tests. The pressure difference between the condenser and the WW is then maintained by operator-controlled venting of the WWs { to the atmosphere. To properly engage the GDCS return flow measurement, an appropriate inlet flow length for the flow meter is required. With the given geometrical line arrangement and with the RPV running at low water level, a sufficient inlet flow length can only be established by reducing the GDCS pressure by ~20 kPa against the RPV pressure. This is accomplished by operator-controlled venting of the GDCS to the atmosphere. The described operator-controlled venting processes imply that preconditioning is completed at a higher than equilibrium pressure because venting evidently allows for pressure reductions only. Hence, a " top-down-approach" is followed for the floating of the system pressure, i.e. the system has to be preconditioned to a pressure which is higher than the equilibrium pressure. . ~. w -e-.

a. ALPHA-410-1 Seite 105 210 Preheating and Purging of Vessels This phase is performed after End of Test (phase n*111.2) or after PCC3 Pool Heating (phase n*85). The Pure Steam Tests require higher system temperatures / pressures to approach equilibrium pressure in a top-down strategy. The system is brought to a higher pressure and air is vented from RPV and GDCS. (Note: Heaters are still on.
