SUMMARY
PANTHERS-PCC (Passive Containment Condenser) testing is performed by SocietA Informazioni Esperienze Termoidrauliche (SIET) in Piacenza Italy; it is sponsored by ENEA as part of a joint study conducted by GE, Ansaldo, ENEA, and ENEL. The test facility consists of a prototype PCC unit, steam supply, air supply, helium supply and vent and condensate vo!umes sufficient to establish PCC thermal-hydraulic performance. Both thermal-hydraulic and component structural demonstration tests are performed in this facility. This report presents the results of the thermal-hydraulic portion of the testing.
The PCC tested is a full-scale, two-module vertical tube heat exchanger designed and built by Ansaldo. The heat exchanger is a prototype unit, built to prototype procedures and using prototype materials. The PCC is installed in a water pool having the appropriate volume for one SBWR PCC assembly.
The primary instrumentation is that required to ascertain heat exchanger thermal-hydraulic performance, by performing mass and energy balances on the facility. Additionally, four heat exchanger tubes are instrumented in such a way that local heat flux information may be obtained.
The main objectives of these tests are to demonstrate that the PCC meets its design performance requirements, provide a sufficient databse for the computer code TRACG to predict its thermal hydraulic performance, and determine and quantify differences in the effects of noncondensable buildup in the condenser between lighter-tham-steam and heavier-than-steam gases.
Both steady-state and transient tests are conducted. For the steady-state tests, steam or an air / steam mixture is injected into the condenser. Some or all of the steam is condensed, and the remaining gases are vented. The inlet as well as the outlet flows are measured and from this data the energy removed by the condenser is determined. Measurements are taken over 15 minutes and time averated.
In the steady-state performance tests with air / steam mixtures, the condenser efficiency decreases as the air mass fraction (ratio between inlet air mass flow rate and total inlet mass flow rate) increases. The condenser efficiency increases as the inlet pressure increases.
Most tests use saturated steam, but superheated steam is also used to measure the effect of superheating on the condenser performance. The results show negligible difference in the condenser performance due to superheat!ng.
Three types of transient tests are conducted. In one, steady-state operation is achieved and then the water level in the pool is decreased. As the tubes uncover, these tests show the effect of decreasing the submerged heat transfer area on the condenser performance. In the second transient test series, the vent line is closed and non-condensable gases are allowed to buildup in the condenser. The condenser pressure rises in order to continue condensing all the steam. The third transient test series are simulated LOCA pressurizations. The LOCA cycles are performed by pressurizing the PCC units with steam, so that both the temperature and pressure effects of a LOCA are simulated. The PCC poolis at ambient temperature at the beginning of each test.

- 1. INTRODUCTION
1.1 Background
The Simplified Boiling Water Reactor (SBWR) is an evolutionary design in boiling water reactors (BWRs). The SBWR has been developed by an international design team from North America, Europe, and Asia and led by the General Electric Company (GE). The design extensively uses the technology of operating BWRs, as well as new developments found in the Advanced BWR (ABWR). A key feature of the SBWR is the use of simple passive systems to respond to any type of design basis event (DBE). These systems utilize passive forces, due to natural circulation, to operate.
One of these systems is the Passive Containment Cooling System (PCCS). The SBWR containment is simlar to existing GE BWRs which have the reactor in a drywell region. The drywell is connected to a wetwell through submerged pipes in the suppression pool, a part of the wetwell. The PCCS consists of three condensers (PCC) connected to the upper drywell gas space. During a postulated loss-of-coolant accident (LOCA), steam in the drywell is driven into the PCCS by the pressure dNference between the wetwell and drywell in combination with the vacuum produced by condensation. The condensate flows down into the Gravity-Driven Cooling System (GDCS) pools in the drywell. The GDCS is another SBWR passive system which provides makeup to the reactor. Non-condensable gases, such as containment nitrogen, are separated in the PCC and vented to the wetwell through submerged pipes in the suppression .
pool. All piping on the PCCS contain no valves, which results in a complete passive operation.
Figure 1.1 is a schematic of PCCS system-1.2 PANTHERS-PCC As part of the SBWR design and U.S. certification program, a prototype heat exchanger for the PCCS was tested in Italy. A four-party effort by GE and the Italian companies ANSALDO, ENEA, and ENEL sponsor that program. The PCC was designed, and a full-scale prototype was manufactured by ANSALDO. The tests were conducted by SIET at the Performance Analysis and Testing of Heat Removal Systems (PANTHERS) facility. These tests measure both the thermal and structural performance of the heat exchanger at various conditions the unit might experience during and after a postulated LOCA. These tests are part of an extensive experimental program to study the performance of passive systems for SBWR certification (Reference 9.1.b). Figure 1.2 is a schematic of the PANTHERS-PCC facility.

3.3.1 Equipment description ;
The PCC heat exchanger is composed by two identical rnodules; one of them - module 1 -is extensively instrumented while the other - module 2 - has few instruments only in some comparison positions. '
Figure 3.2 shows a schematic of test section.
A central 10-inch vertical line with integral flange for connection to pool floor feeds two horizontal ,
cylindrical headers (one for each module), through an upper distributor and two 8-inch horizontal branch pipes, with a mixture of steam and noncondensbie gas. l Steam is condensed inside a bundle of 248 x 2 stainless steel (SA 213 TP 340L) 2-inch 1.8 m long vertical tubes (50.8 mm of outside diameter,1.65 mm of thicknesF); the condensate is collected in two lower cylindncal headers.
The condensate is removed by gravity through two 12-inch annular pl pes connected, by means of two 4-inch pipes, to a common 6-inch main drain line which ends in the condensate tank. At the j headers outlet the drain nozzle also contains the vent line for driving the noncondensable gas separated in the PCC to the vent tank. This line consists in two 8-inch pipes that join in a !
common 10-inch line.
At the ends, the headers are closed by two bolted covers. The PCC unit is supported by 4 saddles. The PCC heat exchanger is submerged in a water pool as shown in Figure 3.3 j The complete two module assembly is designed for 10 MW nomir.al thermal capacity at the following conditions. ;

Module 1 of PCC has been extensively instrumented with thermal-hydraulic instrumentation; module 2 has fewer instrum6ats in reference position for a comparison with module 1.
A summary of PCC condenser thermal-hydraulic instrumentation is given in Appendix A; Figure 3.4 shows the PCC instrument locations.
3.4 PCC containment water pool i
The PCC full-scale prototype, the steam riser, the first length of vent and condensate drain piping ,
are installed inside a rectangular water tank, covered and open to the atmosphere. The main characteristics of the pool are as follows:
totalvolume 173 m3-length 5.47 m ,

height 5.80 m watercapacity 131 rE boil off opening area 2 m2 Normalwaterlevel 4.4 m During testing the nominal level of hot cooling water (100 *C) in the PCC pool is maintained at l 4.4 m; therefore the horizontal axis of the upper header is placed 1.18 m below the pool NWL.
A pool wall is provided with a rectangular opening of 2 x 1 m2, located 250 mm above the NWL, -
for boil-off. The pool is made of fibreglass laminated plastic reinforced by a carbon steel structure. The total average thickness of the laminated fibreglass is 12 mm. Accounting the steel reinforcement and the final fibreglass coating, the total thickness of the pool walls and floor is I 163 mm. j The PCC pool is directly connected to IC pool by means of:
a) an upper circular steam duct, made of fibreglass,1 m OD and about 10.5 m long; the duct is directly connected to the stack and to the atmosphere; b) a lower 8-inch carbon steel pipe for PCC pool water make up.

reference wetwell. ,
The vent tank is located beneath the PCC pool at an elevation such that the vent discharging section is 16 m below the PCC pool bottom and collects the saturated air separated in the PCC with the uncondensed steam.
Air or a mixture of steam and air is discharged from the vent tank directly to the atrnosphere through one of three separate lines: 5",2" and 8" pirang. Each line is equipped with a pressure control valve and a flowrate measurement orirce whose characteristics are reported in Table 3.3.
The main characteristics of the vent tank are as follows:
- intemal diameter 1.7 m
- thickness 12 mm
- total height 6.68 m
- volume 15.0 m3 i
Instrumentation is provided to monitor the following parameters: ,
a) steam-air mixture discharging flow rate; b) temperature and pressure of gases; c) temperature and pressure of liquid; ,
c$ water level.

5.1 Hardware configuration 1
I The PANTHERS PCC test facility is comprised of one data acquisition system for digitally acquired thermal-hydraulic measurements (TH DAS) whose main hard components are:
- data acquisition cards supervisory computer personal computer for derived quantities calculation printer The system is provided with 15 data acquisition 16-bit cards acquiring signals from:
- thermocouples
- absolute and differential pressure transducers and transmitters RTDs I
}
Results from the configured channels are automatically converted to engineering units (SI) by a built-in microprocessor before being transmitted to the personal computer.
Once logging has commenced, measured data are sent to a personal computer where they are stored on disk for subsequent analysis. This personal computer is connected to a second one for monitoring and real-time calculation of derived quantities. A printer is also connected to the net and executes an automatic printout of the principal measurements involved in the data logging at fixed time intervals.
During testing, all the instrumentation signals (compensation thermocouples included) are recorded and stored in real time. The sampling frequency is normally fixed at 0.2 Hz.
5.2 Data Reduction 1 i 5.2.1 Directly measured quantities 5.2.1.1 Absolute and differential pressure Absolute and differential pressures are measured by means of transmitters and transducers. A linear conversion from electrical signal to engineering units is applied in both cases.

5.2.1.2 Temperature r
The signals coming from the thermocouples (mV) are converted in engineering units (*C) f automatically by the DAS in compliance with IEC 584 Standard for K type thermocouples. The signals from the intemal and extemal wall thermocouples brazed on the PCC tubes are connected in series and the difference between the two signals is directly acquired in mV. The ,
t conversion to engineering units, in this case, is performed using a factor drawn from the UNI 7938 Standard tables around the appropriate temperature values.
l The signals coming from resistance thermometer (Q) are also converted automatically in ,
engineering units ('C) in compliance with IEC 751 Standard.

- 6. TEST MATRIX 6.1. Steady-state performance tests The majority of the PANTHERS-PCC testing is steady-state performance testing. For these tests, the facility is placed in a condition where steam or air-steam mixtures are supplied to the PCC, and the condensed vapor and vented gases are. collected. All inlet and outlet flows are measured. The condensate after cooling is collected in a storage tank and the vented gas is released to the atmosphere. Once steady-state conditions are established, data are collected for a period of at least 15 minutes. The time-averaged data are report',a snd analyzed.
Table 6.1 shows the PANTHERS-PCC Steady-State Performance Matrix for Steam-Only Tests.
Thirteen test conditions are included.
- Test conditions 37 through 43 (Test Group P1) can be used to determine the baseline heat s exchanger performance over a range of saturated steam flow rates without the presence of noncondensable gases. Test Group P1 data are compared with design requirements to ,
meet General Objective 1.
- Test Conditions 44 through 49 (Test Group P2) address the effect of superheat conditions in the inlet steam. Test conditions 38,44,45, and 46 can be used to establish the effects of superheat at a relatively low steam flow condition, while Test Conditions 41,47,48, and 49 give the same information at a steam flow rate near rated conditions.
Table 6.2 shows the PANTHERS /PCC Steady-State Performance Matrix for Air-Steam Mixture Tests. Individual test conditions are specified. The independent variables are steam mass flow rate, air mass flow rate, steam superheat conditions, and absolute operating pressure.
- Test Conditions 9,15,18, and 23 (Test Group P3) can be used to compare heat rejection rates over a range of air flow rates to the saturated, steam-only condition determined from Test Condition 41 in the pure steam series. Holding steam flow constant at near rated conditions, these tests yield the effect of air on the condensation process. Test are run at approximately five pressures for each test condition in this group.
- Test Conditions 2,13,16,17,19,22, and 25 (Test Group P4) supplement Test Group P3, in that they define condensation performance at the extremes of the SBWR air / steam mixture ranges, and at severalintermediate points. These tests can be used to quantify noncondensable effects at off-rated conditions. They can be compared to the appropriate Page 33 of 66
Ref: SIET 00393RP95 I
1 Test Conditions in the P1 group. Test are run at approximately five pressures for each test l condition in this group.
Test Conditions 35 and 36 (Test Group PS) further supplement Test Group P4 by extending :
the effect of noncondensable gases over the superheated steam range. These tests can be compared to Test Conditions 48 and 49 to establish the effect of air content at the same ,
superheat condition, and to Test Condition 23 at the same air flow, but with saturated steam. Tests are run at approximately five pressures for each test condition in this group.
Test Conditions 1,3,4,5,6,7,8,10,11,12,14,20,21, and 24 (Test Group P6) are lower i priority tests. They are run to supplement the previously identified tests by increasing the data density within the already established air / steam flow map. Tests are run at one pressure for each test condition in this group.
6.2 Transient test conditions PANTHERS-PCC transient tests can be used to establish noncondensable buildup effects and PCC pool water level effects. They are not intended to be systems transient tests.
In addition, TH data have been recorded also during Simulated LOCA Pressurization tests whose main purpose was to confirm the PCC structural design.
Table 6.3 shows the PANTHERS-PCC noncondensable buildup test matrix. Either test conditions are specified as Test Group P7. In these test conditions, steam is supplied at a constant rate, and steady-state conditions established, similar to what was done in the steady-state performance tests. Air, helium, or air / helium mixtures are then injected into the steam supply, with the vent line closed, and the transient degradation in heat transfer performance is measured, as a function of the total noncondensable mass injected.
Tests Conditions 50 and 51 provide a baseline condition with air as the only noncondensable. Air is similar to nitrogen in molecular weight, and is heavier then steam.
Test Conditions 52 and 53 are similar to Test Conditions 50 and 51 with the steam superheated. Test Conditions 75 and 76 are repeats of Test Conditions 50 and 51, but utilize helium as the noncondensable gas instead of air. Helium is lighter than steam, and will mix in a manner similar to hydrogen. The results of these four tests can be compared to establish performance differences between lighter-than-steam and heavier-than-steam gases as they build up in the heat exchanger tubes. Test Conditions 77 and 78 can be Page 34 of 66
~
Ref: SIET 00393RP95- .
used to evaluate the effects of a combination of air and helium concurrently flowing into the heat exchanger.
- Test Group P7 data will be evaluated to meet the requirements of General Objective 3.
Table 6.4 shows the PANTHERS-PCC Pool Water Level Effect Test Matrix. Three test conditions are specified as Test Group P8. In these test conditions, steam and air / steam mixtures are supplied to the PCC heat exchanger, and steady-state conditions established, similar to the steady-state performance tests. In these tests, however, the water level in the PCC pool is allowed to drop and the PCC tubes to uncover. Both the PCC pool level and the PCC heat rejection rate are rnonitored as a function of time.
- Test Conditions 54,55, and 56 establish the effects of water level in the PCC pool for a range of steam and air / steam supply rates to the PCC. Data from Test Conditions 54,55, and 56 can be compared to Test Conditions 41,15, and 25, respectively, to obtain the effects of lowered water level on condensation performance. Test Conditions 54 and 55 can be compared to establish the effect of air content on the rate of pool boiloff.

- Test Groups P1 through PS, P7 and P8 provide a database for TRACG quaiification and meet General Objective 2.
Ten LOCA tests are performed by pressurizing the PCC units with steam, so that both the i
temperature and pressure effects of a LOCA are simulated. The PCC pool is at ambient temperature at the beginning of a test, but is allowed to heat up to saturation as each cycle ,
proceeds. Table 6.5 gives the time history of the LOCA pressurizations. Each LOCA cycle lasts approximately 30 minutes. Ten cycles were performed. The main purpose of this test series is to confirm the PCC structural design, but the TH data were recorded.

- 7. TEST RESULTS 7.1 Steady state performance tests A total number of 97 steady-state tests was performed. For these tests, the test loop and PCC were first purged with steam to remove any residual air from the system and to heat the PCC pool to saturation. Then the required steam only or air-steam mixtures with the flowrates specified in section 6 are supplied to the PCC, and steady-state conditions are reached. The system was maintained in steady-state condition for a period of 10 minutes before starting data recording.
Measurements were then recorded over a steady-state period of at least 15 minutes and time average over the 15 minute period; the data recording start /stop time is specified in the Apparent Test Results.
For steam only tests, the vent line was isolated by installation of a blind flange, and the condensate was drained to the condensate tank. The inlet pressure was allowed to stabilize while maintaining full condensation.
For the air-steam mixture tests, vent line and drain line were both open. The desired inlet pressure was established by setting the position of the vent tank flow control valve.
The average values of the following main parameters were determined:
Test number Each test is identified with a test number formed by a T' followed by the test condition number (as reported in section 6), an underscore and a progressive number. The progressive number is chronological and it refers to the recorded file number. The system of numbering includes all the recorded files, but in the tables only the numbers of the valid test files are listed.

- heat rejection rate The measurement uncertainty for each average value was also determined.
7.2 Transient tests A total number of 21 transient tests was performed. Three types of transient tests were run in the PANTHERS-PCC test program.
Two of these measured the thermal-hydraulic performance of the condenser under varying conditions:
- noncondensable gas buildup tests (8 tests)
- pool water level effect tests (3 tests)
The third was a set of ten LOCA simulation tests. The main purpose of LOCA simulation tests was structural integrity study but, since all thermal-hydraulic measurements were recorded, they also supply data on the start-up of the' condenser under accident conditions.

Steam or steam / air mixtures were supplied to the PCC at constant rates and steady-state conditions were established and held for at least ten minutes. Then pool water level was allowed to drop by boiloff and draining. For the steam only test, the vent line was closed. For the air- l steam mixture tests, the position of the vent tank flow control valve remained fixed. The two conditions for stopping water level drop were: ;
i
- the inlet pressure reached 790 kPa or
- the IC pool waterlevel reached 1.3 m For all tests, the water level drop was stopped for the second condition. Then the water level was increased till normal water level was re-established. The rate of water level decrease / increase !
was about 1 cm/ min.
Plots of inlet pressure and heat rejection rate vs. pool water level for each test are presented in !
Figures 7.10 through 7.15. In all three tests, the heat rejection rate increases as the water level l decreases down to approximately the top of the condenser tubes. As the water level continues ,
decreasing, the heat rejection rate decreases and the inlet pressure increases. There is a slight histeresis in the inlet pressure between water level decrease and water level increase. _

- 8. CONCLUSIONS 1
Data from the PANTHERS-PCC test program address the objectives given in Section 2. Some of these objectives are met by this report. Each of these objectives are discussed below.
General Objective 1: Demonstrate that the prototype PCC heat exchanger is capable of meeting its design requirements for heat rejection. (Component Performance)
Data collected by PANTHERS-PCC can be used to compare the heat removal from a prototype condenser with the SBWR design requirements. Steady-state tests with steam only can be used to derive the condenser performance at design conditions.
General Objective 2: Provide a sufficient database to confirm the adequacy of TRACG to predict the quasi-steady-heat rejection performance of a prototype PCC heat exchanger, over a range of non-condensable gas flow rates, steam flow rates, operating pressures, and superheat cond;tions, that span and bound the SBWR range. (Steady-State Separate Effects)
The extensive database presented in this report satisfy this objective.
General Objective 3: Determine and quantify any differences in the effects of noncondensable buildup in the PCC heat exchanger tubes between lighter-than-steam and heavier-than-steam gases. (ConceptDemonstration)
Test Conditions 50 through 53 and 75 through 78 provide data to satisfy this objective.
Specific Objective (a): measure the steady-state heat removal capability over the expected range of SBWR conditions:
inlet pressure concentration of noncondensable gases PCC differential pressure pool-side bulk average water temperature pool-side water level The extensive database presented in this report satisfy this object;ve. Comparison between the PANTHERS-PCC test conditions and the expected SBWR condiSons is given in Reference 9.1.b.
Page 39 of 66
Ref: SIET 00393RP95 Specific Objective (b): confirm that when a mixture of steam and noncondensable gases flows into the PCC, the uncondensed gases will be discharged from the vent line and the condensate will be discharged from the drain line; The operation of the PCC at PANTHERS confirms the separation of the uncondensed gases and the condensate in the lower header and, thus, satisfies this objective.
Specific Objective (c): confirm that tube-side heat transfer and flow rates are stable and without large fluctuations; The stable operation of the PCC at PANTHERS satisfies this objective.
Specific Objective (d): confirm that there is no condensation water hammer during the expected start-up, shutdown and operating modes of the PCC; The PCC was operated under many modes at PANTHERS. Also in the process of changing steady-state test conditions, the steam and/or non-condensable gas flows were varied. At no time during any of these operating modes was water hammer observed. Therefore, these tests satisfy this objective.
Specific Objective (e): measure the inside and outside wall temperature at typical tube locations to:
i) provide diagnostic iniormation for investigation of unexpected condenser performance ii) provide information useful to confirm the understanding of tube side performance iii) provide a fundamental data base for confirmation of TRACG simulation of PCC performance; As shown in the discussion on the instrumentation, on four PCC tubes, thermocouples were installed on the inside and outside walls. Data from these instruments satisfy this objective.
