- 1. Introduction 1.1 General Description and Purpose of Test PANDA is a full height 1/25 volume scale model of the SBWR system designed to model thermal hydraulic performance and post LOCA decay heat removal of the PCCs. Both state and transient performance simulations have been carried out. Testing at the same thermal hydraulic conditions a.s previously tested in GIRAFFE and PANTHERS was performed so that scate-specific effects may be quantified [1]. The results of the steady-state tests are presented in this report.
1.2 Purpose of Report This Data Transmittal Report (DTR) is compiled t+ accordance with the requirements specifie Test Plan and Procedures for Steady State Tests (2]. The report covers the results for the PANDA steady-state PCC performance tests S1 through S6 and S10 through S13.
The DTR provides detailed information on the following:
Test objectives Test matrix
)
Test results Conclusions The data record composition is described in the appendix. The general test program objectiv PANDA facility, instrumentation, data acquisition system, facility characterization tests, and PANDA experimental data base are desenbed in separate reports (3 5].
Two ATRs summarize the apparent results and include: test number, test objective, test date and time, data recording period, data analysis period, name of data file, list of failed or unavailable instruments considered. to be required for the test, list of required instruments with zero or reference check points not in tolerance or in over-range or under range dunng test, deviations from test procedure, and problems that occurred during the test. Statements are made whether test objectives have been reached and the data recorded correctly. For each test a table of j
i results with average and standard deviation for the required measurements, as required by [2i and time history plots of flow rate measurements over the reference test time are provided.

- 2. Test objectives 2.1 General Objectives The objectives of the PCC steady state 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:
ALPHA 609-0 / Page 6 (a) measure 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.
2.2 Specific Objectives Investigate the influence of noncondensible gases on condensation rates investigate attainable pressures for a given flow rate of pure steam e
Demonstrate repeatability Investigate the influence of PCC pool level on heat removal capability l
{
Collect data for investigation of the influence of scale as a counterpart test to GIRAFFE (3 tubes) and PANTHERS (full scale); 20 tubes / condenser for PANDA.

- 3. Test Matrix l
The series of steady-state tests was conducted using one of the PCC condensers (Table 3.1).
I The facility was configured as described in [3] to inject known flow rates of saturated steam and air directly into the heat exchanger. The condenser inlet pressure was maintained at 300 kPa for j
all tests with air flow by controlling the wetwell pressure. The pool surface level in WW2 was below the PCC3 vent line exit. Steam and air flows to the heat exchanger were controlled and l
measured while condenser drain and vent flows were measured. Four tests were conducted with various air flows and a constant steam flow of 0.195 kg/s (S2 to SS). In addition, two tests without air flow were run (S1 and S6); one with the same steam flow as the steam / air tests (S1)
I and one with a steam flow equivalent to the expecte:1 steam condensing capacity at 3 bars (S6).
The PCC3 vent was closed for these tests without air flow. Tests S10, S11, and S12 are repetitions, respectively, of S3, SS, and S6. Test S13 is a repetition of S12, but with the PCC poollevellowered to the bottom of the upper PCC header.

This section details the form of the energy balances and lists t instrumentation used in the calculations. Also included is a formulatio estimates and calculation of condenser efficiency. The results of these ca tables at :he end of this section.

All of the inlet steam flow must pass either through the drain as conoensat as vapor:

The vent mass flow rate is the sum of the vapor and air flow rates:

(4.5)
After noting that, for steady-state conditions, the air mass flow rate through th identical to the inlet air flow rate, eqns. 4.2-4.5 are used to write the energy ba the measured inlet and drain flow rates:

The second energy balance, which can be used as a check against the first, is f terms of inlet and vent flow rates, eliminating the drain flow rate measurement:

4.3 Energy Balance Uncertainty A simple error propagation formula is used to estimate l
uncertainty in tha energy balance.
Uncertainties arise from temperature and frow measurement errors. Error ir. temperature re) in density and enthalpy errors. However, these are small compared to errors in the measured volumetric flow rate and so they are neglected.

Flow rrate uncertainties are taken from [6], where uncertainties for the feed, vent, and drain flow rates were estimated to be 1.5,2, and 2%, respectively. An indication of the steadiness of the condenser heat load over the measurement interval is obtained by substituting the standard deviation of the flow rate for the uncertainty terms in the abovo two equations. The calculated values for these indications of steadiness are listed under the heading 7 and are included with the error estimates in Table 4.3.

- 5. Conclusions 5.1 Adequacy of Test Data l
Based on the analysis of test data in (4) and (5] the test acceptance criteria have clearly been attained. All zero ind instrument checks for each steady state test have been successfully completed and instrument readings were inside the permitted range. During subsequent data analysis no findings have been made that influence the quality of test results. Test reproducibility has been demonstrated with the repetition of three experiments (S3/S10, S5/S11, S6/S12):
Pure steam test:
Steam / air tests:
l Based on all information available to date, all data for the steady state tests are adequate.
5.2 Applicability to Test Objectives The test objectives, as stated in section two of this report, have been reached.
