ABSTRACT Natural circulation instability tests were performed in the Multifunction Thermal Hydraulic Test Facility KATHY in Karlstein, Germany. One type of test involved stepping up test assembly power in oscillating flow until failure to rewet occurs based on temperature observation. A second type of test introduced a simulated neutronic feedback to dynamically change the power, again with flow oscillations up to the point of failure to rewet. Two tests featured a transient inlet temperature. The largest flow oscillations in the test program ranged from

~ 7 kilograms per second (kg/s) to 13 kg/s. The tests varied system pressure (7 and 8 megapascals), water level in the steam-water separator (0.4 and 1.1 meters), and inlet subcooling (20 Kelvin and 35 Kelvin). A full-scale boiling-water reactor rod bundle was simulated in these tests. Before the dynamic instability tests, the rod bundle was characterized with single-phase- and two-phase pressure drop tests. Steady-state critical power tests were also performed to characterize the conditions under which steady-state dryout occurs. This report describes the tests performed as part of this program. This research effort supported the continued development and benchmarking of the U.S. Nuclear Regulatory Commission (NRC) reactor systems analysis computer code with state-of-the-art, realistic modeling capabilities thereby enabling more effective use of confirmatory calculations in licensing reviews.

EXECUTIVE

SUMMARY

A variety of critical heat flux (CHF), pressure drop, and flow instability tests were performed in the Multifunction Thermal Hydraulic Test Facility KATHY of the laboratories of Framatome GmbH, located in Karlstein, Germany, in 2016. These tests were performed on a boiling-water reactor test bundle configuration. This research effort supported the continued development and benchmarking of the U.S. Nuclear Regulatory Commission (NRC) reactor systems analysis computer code with state-of-the-art, realistic modeling capabilities thereby enabling more effective use of confirmatory calculations in licensing reviews.

Steady-state CHF tests were performed with the test bundle STS-123.01 from August 22 to 24, 2016. The thermal-hydraulic conditions covered pressures from 5.5 megapascals (MPa) to 8.3 MPa, flow rates from 3.0 to 12.6 kilograms per second (kg/s) and inlet temperatures from 224 degrees Celsius (C) to 289 degrees C. Six high-powered heater rods with a maximum radial peaking factor of ~ 1.26 were placed in the test bundle.

Most CHF events were observed at rod position 69, at thermocouple (TC)-level 1 for flow rates up to ~ 7 kg/s and with a transition to TC-level 3 for larger flow rates. Less frequent CHF events were observed at rod position 23 TC-level 1 and rod position 87 TC-level 1.

Single- and two-phase pressure drop tests were performed with the test bundle STS-123.02 on September 23, 2016. The nominal system pressure was 6.9 MPa. The flow rates ranged from 3.2 to 18.9 kg/s at an inlet temperature of 260 degrees C for single-phase and 274 degrees C for two-phase pressure drop tests.

The largest single-phase pressure drop was ~ 700 millibar (mbar) at the measurement points S73 CP1013 and S73 CP210 for a flow rate of 18.9 kg/s. The parallel installed K (narrow measurement range) and G (wide measurement range) differential pressure transducers showed good agreement.

The largest two-phase pressure drop was close to 1500 mbar at the measurement points S73 CP1013 and S73 CP210 for a flow rate of 15.8 kg/s and a bundle power of 8 megawatts.

The parallel installed K and G differential pressure transducers showed good agreement as long as the end of measurement range for the K transducers was not reached (S73 CP210K and S73 CP219K).

Natural circulation instability tests were performed with the test bundle STS-123.03 from December 10 to 20, 2016. The nominal thermal-hydraulic conditions varied from 7.0 to 8.0 MPa in pressure, 20 to 35 Kelvin in subcooling at the inlet, and 0.4- to 1.1-meter level in the separator. Two types of tests were performed. In the first type, the test bundle power was increased stepwise until a failure to rewet was observed based on temperature excursion. In the second type, a separate neutronic feedback power module calculated online an additional dynamic power contribution.

In total, 41 test runs were performed without simulated neutronic feedback and 19 test runs were performed with simulated neutronic feedback. These tests also include two tests with transient inlet temperature. The largest mass flow oscillation was observed ranging from

~ 7 kg/s to ~ 13 kg/s during test run T01.02.

2 TEST LOOP Figure 2-1 shows that the thermal-hydraulic test facility is a high-pressure water heat transfer loop containing a test vessel with the test assembly and upper and lower electrical bus bars, high-pressure coolers, a direct contact condenser, an electrically heated pressurizer, and the main circulation pumps. The figure shows two inlet flow lines of different sizes. The different sizes allow fine control of the flow rate over a broad range. The direct current power supply consists of four thyristor controlled rectifiers.

As shown in Figure 2-1, the forced flow loop may be reconfigured into a natural circulation loop.

The natural circulation loop consists of the test vessel housing, the test bundle with the electric power supply system, and the riser that connects the upper plenum of the test section with the steam-water separator, and the downcomer. This configuration has no circulation pump. To measure the mass flow rate oscillations, a turbine flow meter is installed in the horizontal inlet pipe coming from the downcomer. Inside the steam-water separator, the two-phase flow mixture is passively separated. The saturated water leaves the separator at the bottom and is mixed in the vertical feed water injector with colder feed water to adjust the specified inlet subcooling. To discharge the saturated steam generated in the test bundle and to adjust the inlet subcooling, the natural circulation loop is connected to the 22-megawatt high-pressure boiler system of the Karlstein laboratory. The saturated steam leaves the separator at the top and flows to the condenser of the boiler system.

The Data Acquisition System (DAQ) samples the analog signals of the loop instrumentation, digitizing them with 16-bit analog-to-digital converters and stores the signals on hard disk. The hardware of the DAQ is based on National Instruments SCXI-bus components. 1 Six personal computers (PCs) are used: one controls the acquisition and data flow; three provide display and visualization of selected channels, including thermocouples (TCs), during tests; one is used to display test results following each test run; and one computer is used by the test monitoring engineer to access results directly. The data acquisition software is based on the programming language of LabView. Evaluation software is applied to transfer the raw data (voltage) into physical values (e.g., pressure, temperature) is written in C.

The same direct current power supply provides power to each of the test bundles STS-123.01, STS-123.02, and STS-123.03. The design power is ~ 20 megawatts. The current is measured by DynAmp transformer and redundantly by shunts, which leads to several measurement points of bundle power:

S73_FC01: Measured gross bundle power. Current is measured by shunts (S73CE03IS).

P_FC01Net: Measured net bundle power. Current is measured by shunts (S73CE03IS).

S73_FC02: Measured gross bundle power. Current is measured by the DynAmp-transformer (S73_CE09IWA).

P_FC02Net: Measured net bundle power. Current is measured by the DynAmp-transformer (S73_CE09IWA).

1 Getting Started with SCXI, National Instruments Corporation, Report No. 320515F-01, July 2000 edition.

2-1

The gross bundle power includes the power consumption of the external compensation rods (P_Comp_Bundle) for the part-length heater rods. The net bundle power excludes the power consumption of the external compensation rods for the part-length heater rods. Finally, the alias POWER points to the measurement point P_FC02Net.

2.5 Radial Power Distribution and Thermocouple Positions STS-123.02 and STS-123.03 The pressure drop tests were performed with the test bundle STS-123.02.

The instability tests were performed with the test bundle STS-123.03.

The test bundle STS-123.01 was inspected after completing the CHF tests and reassembled before the pressure drop tests on STS-123.02.

Together with the reassembling of STS-123.02, several heater rods were replaced to increase the number of available heater rod TCs.

The reassembling resulted in the following differences:

Pos. STS-123.01 STS-123.02/STS-123.03 17 W3012 W3C02B 23 W3D08B W3C01B 36 W3016 W3C03B 58 W3D07B W3D08B 59 W1D07B W1D11B 62 W3D11B W3D06B 83 W3023 W3C04B 86 W1D11B W1D14B 98 W3D06B W3D11B The test bundles STS-123.02 and STS-123.03 have the same radial power distributions and TC positions.

Figure 2-8 to Figure 2-10 show the radial power distribution.

Figure 2-11 shows the TC positions.

Of the TCs monitored during test STS-123.02, the following nonoperational TCs were observed:

17/2Z From beginning to end 69/2Z From beginning to end 88/4Z From beginning to end 96/4Z From beginning to end 97/4X From beginning to end 98/5Z From beginning to end Of the TCs monitored during test STS-123.03, the following nonoperational TCs were observed:

6/3X From beginning to end 17/2Z From beginning to end 88/4Z From beginning to end 98/5Z From beginning to end Between tests, repairs to TCs were attempted and were sometimes successful. This is the reason that the number of nonoperational TCs in test STS-123.03 is lower than in STS-123.02.

4 INSTABILITY TEST RESULTS 4.1 Natural Circulation Instability Tests The module simulating neutronic feedback (SINAN) is based on the measured inlet flow rate.

Without this feedback module active, the power is held constant.

STS-123.03 Date of tests December 10 to 20, 2016 Test runs 41 without SINAN feedback 19 with SINAN feedback (Thereof) replicate test runs 1 (Thereof) transient test runs 2 4.2 Test Matrix Appendix A specifies the test program.

Appendix B documents the test matrix of the performed instability tests, their initial thermal-hydraulic conditions, and SINAN module parameters of Tau, Rhosub, and Vrcmul. Tau is a parameter in the SINAN module that characterizes the fuel thermal inertia, Rhosub is a parameter that characterizes modal harmonics in the neutron kinetics model, and Vrcmul is a parameter that characterizes the strength of the simulated void reactivity feedback.

The enveloping instability test conditions were as follows:

System pressure 7.0 MPa and 8.0 MPa

Inlet subcooling 20 Kelvin (K) and 35 K

Water level 0.4 meter (m) and 1.1 m (in the steam-water separator)

Tau* 2.0 second (s), 2.5 s, and 3.7 s

Rhosub* 0.0 dollars ($), 0.8 $, 1.0 $, and 1.2 $

Transient test condition Test bundle STS-123.03 4.3 Summary of Test Data According to the test matrix, the non-SINAN tests were started at a certain power level. In the subsequent test runs, the initial power level was increased in small increments.

The SINAN tests applied a neutronic feedback power module. It was independently operated on a separate PC.

Appendix B and the 9th plot of Appendix D through Appendix KKK give a rough overview of the parametrized SINAN coefficients (e.g., Vrcmul, Rhosub, and Tau) over the time. Nevertheless, for detailed evaluation, the corresponding values as a function of time have to be used.

The measurement point Sync_SINAN (1st plot in Appendix D through Appendix KKK) indicates the time when SINAN was set active.

Also, two tests were performed with transient inlet temperatures (transient tests). Due to the nature of these tests, the water level inside the separator was not constant.

Appendix C summarizes the initial test conditions, the separator water level, and whether SINAN was active.

4.4 Replicate Test Procedure As part of the instability measurements, one repeatability test was performed. The first test performed without SINAN feedback was agreed upon to be the repeatability point and was performed on the final day of testing. The repeatability measurement used the same power search as was used in the first test. The acceptance criteria for this test were the power level at the point of oscillation inception being within 2 percent and the oscillation magnitude at the time of initial dryout being within 2 percent.

The repeatability measurements were made and showed very good agreement to the initial tests. Results were well within the agreed-upon acceptance criteria and show no noticeable changes in loop behavior over the test campaign.

6 EVALUATION OF THE MEASURED DATA 6.1 Pressure Drop Results over the Test Bundle The positions of the lower and the upper tap refer to the lower end of the ceramic liner.

Appendix A gives the nominal boundary conditions (test matrix) for the pressure drop tests.

The differential pressure drop measurement IDs along the test bundle are as follows:

S73 CP222

S73 CP2227

S73 CP2728

S73 CP2829

S73 CP2930

S73 CP309

S73 CP1012

S73 CP1013

S73 CP210

S73 CP219

S73 CP3013

S73 CP10CP05 6.1.1 Measurement Range As measured pressure drops (the asterisk

is the placeholder for the above-mentioned measurement IDs):

*K: narrow measurement range

*G: wide measurement range 6-1

6.1.2 Geodetic Correction Geodetically corrected pressure drops with regard to the density of the pressure gauge line inside the annular space outside of the flow channel and inside the test vessel. This report does not include the geodetic correction of the water column inside the flow channel because the axial density distribution inside the test bundle is unknown.

The total pressure drop is defined as follows (sample measurement ID: S73_CP1012):

S73_CP1012K_Korr = S73_CP1012K + 1012

g

h1012 where S73_CP1012K = measured value h1012 = difference of level of pressure taps (e.g., tap 10 and tap 12) 1012 = average density of the relevant pressure gauge tube, calculated from temperature measurements on the surface of the pressure gauge tube 1012 = pressure tap numbers (10 and 12) g = gravity constant = 9.81 (m/s2) 6.1.3 Irreversible Correction The local quality inside the test bundle is not evaluated. As such, void distributions within the bundle are not known. Therefore, the irreversible pressure loss needs to be separately evaluated, consistent with the methodology that uses these data.

6.2 Pressure Drop Results over the Test Loop 6.2.1 Geodetic Correction Geodetically corrected pressure drops (IDs ending with *Korr) are calculated with regard to the difference in density of the pressure gauge line and the fluid.

The calculation is based on the assumption that the velocity is equal at both pressure taps in a single flow regime.

The total pressure drop is defined as follows (sample measurement ID: S73_CP15):

CP15_Korr = S73_CP15 + g

h15 * (1 - 15) where S73_CP15 = measured value h15 = difference of level of pressure taps 15 = actual fluid density = f (t, p system) 1 = density in the pressure gauge line = f (20 °C, p system) 15 = pressure tap number g = gravity constant = 9.81 (m/s2) 6-2

The exception is CP14_Korr, due to the unknown fluid density differences inside the riser compared to the water level inside the separator. It was determined as:

CP14_Korr = S73_CP14 + 14

g

h14 If further evaluations are performed on CP14_Korr, this has to be taken into account.

The densities were calculated from the following fluid temperatures:

11 = f (S73_CT20, p_system) used for measurement ID: S73_CP11 12 = Rho_inlet = f (T_inlet, p_system) used for measurement ID: S73_CP12 14 = f (20 °C, p_system) used for measurement ID: S73_CP14 15 = separator

0.33 + Downcomer

0.67 used for measurement ID: S73_CP15, with:

separator = f (S73_CT18, p system)

Downcomer = f (S73_CT20, p system)

The temperature within the span of height h15 (along the feedwater injector) shows a temperature profile. The upstream section temperature (before the feedwater injector) is measured by S73_CT18. The downstream section (after the feedwater injector) is measured by S73_CT20. The ratio 0.33 to 0.67 represents the normalized lengths of the two sections.

16 = f (X_Outlet, p_system) used for measurement ID: S73 CP16, with:

X_Outlet = f (H_Outlet)

H_Outlet = H_Inl + (power / M_flow)

H_Inl = f (S73 CP04, T_inlet) 6.2.2 Irreversible Correction These pressure drops (ending with *irr) are calculated as the (*Korr) pressure drops as described before but with respect to the calculated medium (steam/water) velocities at both pressure taps due to possibly different flow areas at the pressure taps.

The measurement channels ending on *irr were calculated with these flow areas:

CP11_irr: Upper and lower taps of downcomer CP12(A or B)_irr: Lower tap of downcomer and BOHL CP14_irr: EOHL to steam-water separator; not calculated due to the unknown velocities CP15_irr: Lower tap of steam-water separator to upper tap of downcomer CP16_irr: Along the riser 6-3

6.3 System Pressure The system pressure p_system is an alias of S73 CP05B and is measured by a gauge pressure transducer. Therefore, the absolute pressure is obtained by:

pabs = pm + k where pabs = absolute system pressure at test section outlet in bar pm = pressure measured by the gauge pressure transducer k = 1.0 bar 6.4 Water Level in the Steam-Water Separator The water level in the steam-water separator is determined with the following formula:

H ( 1 " ) g pm LEVEL _ SEP =

( ' " ) g where LEVEL_SEP = separator level in m H = distance between the pressure taps pm = value of differential pressure S73_CL01B

, = density of saturated water (SEP_LIQUID) and steam (SEP_STEAM) of separator pressure (S73_CP08B) 1 = density in the measuring gauge line of S73_CL01B = f (20 °C, p_system) g = gravity constant = 9.81 m/s² 6.5 Inlet Mass Flow Instability Test STS-123.03 6.5.1 Turbine Flow Meter S73 CF08 The instability test loop cannot be equipped with a flow measurement by means of a nozzle at the inlet, as its pressure drop would influence the natural circulation characteristics. Therefore, the instability test STS-123.03 volumetric flow S73 CF08 is measured by a turbine flow meter at the inlet of the test vessel.

The output value of the turbine flow meter is a function of the measured impulses. The turbine meter was calibrated in a DAkks (Deutsche Akkreditierungsstelle GmbH)-accredited laboratory (test certificate: 17-001, D-PL-15108-01 2016-05, dated May 20, 2016).

The mass flow was calculated as:

S73_CM08 = S73 CF08

Rho_CF08, (with: Rho_CF08 = f [S73 CP04, T_inlet])

6-4

A redundant and diversified check at stationary mass flows was performed during the commissioning of steady-state CHF test STS-123.01 to check the turbine flow meter against the mass flow reference M_CF03G (by means of nozzle flow measurement) of the KATHY test loop. Therefore, the turbine flow meter was installed during STS-123.01 in the inlet pipeline.

Two measurement channels of the turbine flow meter are available: S73 CF06 in liters per second l/s and M_CF06 in kg/s. Both channels are calculated and measured by the spinning of the turbine.

These were the comparable results:

Before instability test STS-123.03, the turbine flow meter was then installed in the inlet pipeline of the instability test loop.

The turbine flow meter should be evaluated only for (semi-) stationary mass flow conditions.

Because of its measurement principle, it shows a lag/slip for transient mass flows.

6.5.2 Mass Evaluation by Inlet Pressure Drop S73 CP12 The inlet pressure drop S73 CP12B was separately postprocessed to derive the dynamic inlet mass flows during the instability test STS-123.03.

The inlet flow is measured by a turbine device that is accurate for steady-state and slow transients. For oscillatory flow, the measurement suffers from the inertia problem that underestimates the magnitude of flow oscillations and displays a time delay. This problem is solved by relying on pressure drop measurements across two points in the inlet piping. Since the two pressure taps are not close to each other, flow inertia must be taken into account. The flow is determined by solving the differential equation:

dm k I = p ( t ) m ( t ) m ( t )

dt 2 A2 Where I = Flow inertia, sum of length-to-area for all pipe segments, [m-1]

m = Mass flow rate, [kg/s]

t = Time, [s]

p = Pressure drop, [pascals]

k = Loss coefficient [-]

= Fluid density, [kg/m3]

A = Reference area for the definition of loss coefficient, taken as 0.0064516 m2 (10 square inches)

The differential equation above assumes the form losses to be symmetrical in the forward and reverse directions. The absolute value of the flow rate in the last term is needed to obtain flow in either direction. A central-differencing scheme (semi-implicit) is used to obtain the flow rate.

Thus, m ( t + t ) m ( t ) 1 k I

t

= ( p ( t + t ) + p ( t ) )

2 8 A2

( m ( t + t ) + m ( t ) ) m ( t + t ) + m ( t )

Solution of the algebraic equation resulting from the central differencing scheme requires a priori knowledge of the flow direction. This is done by using the sign of the mass flow rate produced by an explicit method (identified with a tilde). The solution is reduced to solving a quadratic equation with the coefficients:

k

= a sign m ( t + t ) + m ( t )

8 A2 I b = 1 + 2a m ( t )

t

= c a m 2 ( t ) m ( t )

2I

( p ( t + t ) + p ( t ) )

6-6

The new time step mass flow rate is obtained from:

b + b 2 4ac m ( t + t ) =

2a Appendix LLL gives the results of the postprocessed mass flows.

6.6 Inlet Subcooling The inlet subcooling DH_Inlet is = f (S73 CP04, T_inlet). T_inlet is derived by the measured inlet temperature measurement point S73_CT03B.

9 NOTES 9.1 Steady-State Tests STS-123.01, STS-123.02 During steady-state test STS-123.01, analysts noticed that some differential pressure taps over the test bundle were blocked at hot conditions. The test bundle STS-123.01 was inspected and the blockages were removed. Afterwards, the pressure drop tests were run with the test bundle STS-123.02.

TC 59/1Z was defective through STS-123.01. Position 59 was a high-powered heater rod and 1Z is the most downstream TC location. Level 1 is expected to show CHF with small mass flow rates. Therefore, the STS-123.01 CHF tests were started with several additional scoping CHF tests to demonstrate that rod position 59 was not the leading position in the test bundle. These scoping CHF tests were the test runs STS-123.01-294.01 to -299.04. For these tests, the mass flow rate was increased to force CHF detections to TC levels 2 to 5. No CHF was monitored at the upstream TCs of the heater rod on position 59.

9.2 Instability Test STS-123.03 On December 7, 2016, during the commissioning of the instability test loop, condensation hammers were noticed in the steam-water mixing chamber. Analysts assumed that the steam quencher pipe inside was damaged.

From December 8 to 9, 2016, a second steam-water mixing chamber was routed and connected to the instability test loop. This new setup was successfully commissioned on December 10, 2016.

The high subcooling test runs were performed at approximately 30 K-35 K.

APPENDIX A REQUIREMENTS FOR STEADY-STATE AND ATWS-I TESTS A.1 Introduction and Summary This document defines the test hardware and the test program for the steady-state part of the anticipated transient without SCRAM instability (ATWS-I) test. The steady-state part is considered as the pretest to the instability test. Test data will be applied to evaluate the pressure loss coefficients of the spacers and the bundle dryout performance at steady-state conditions.

A.2 Pressure Drop and Boiling Transition Test Program A.2.1 Program Scope Framatome will supply the test equipment.

A.2.2 Experimental Measurements The following measurements shall be recorded simultaneously for each set of tests performed in this experimental program:

bundle power (kilowatts (kW))

assembly inlet flow (kilograms per second (kg/s))

assembly inlet temperature (degrees Celsius (°C))

assembly inlet subcooling determined based on the exit pressure as used for the previous tests (kilojoules per kilogram (kJ/kg))

assembly inlet subcooling determined based on the inlet pressure (kJ/kg)

assembly exit pressure (bar)

differential pressures along the test assembly (millibar (mbar))

rod and thermocouple experiencing boiling transition A.2.3 Dryout Tests STS-123.01 Tests shall be conducted with an electrically heated bundle using a downskew axial power profile for the determination of the boiling transition behavior. The tests shall specifically determine the radial and axial location of boiling transition and the test assembly power at which boiling transition is detected.

A-1

Figure 2-4 to Figure 2-11 in the main body of this report show the bundle average local peaking pattern (distribution of rod types) and rod positions with thermocouple instrumentation (bold circles). Rod type 1 includes heater rods with the highest radial power peaking of about 1.3. The radial power peaking of type 2 heater rods is about 1.2, type 3 rods 1.1, and type 4 rods about 1.0.

The test matrix and pressure variation shown shall be followed for the peaking pattern given in Figure 2-4 to Figure 2-6. A minimum of two replicate points shall have been repeated at the end of each day. One of these points will be a repeat of the first data point taken during the days testing. One of these points shall include the following state point: assembly exit pressure 69 bar, inlet mass flow rate of 7 kg/s, inlet subcooling of 90 kJ/kg. After the completion of measurements for every mass flow, one replicate point shall be repeated to confirm the tested performance. Replicate points shall also be repeated after every occurrence in the loop (e.g., trip of power or failure of a bundle component). The table below shows the total estimated number of steady-state critical power data points, including replicates.

Assembly performance can affect these criteria. If necessary, these criteria can be changed by the test team with the concurrence of Framatome GmbH. The criteria applied for each critical power measurement shall be reported.

A.2.4 Pressure Drop Measurements STS-123.02 Pressure drop measurements shall be made to determine component (mainly spacer grid) pressure loss for conditions of single- and two-phase flow. The single-phase pressure drop shall be determined at a pressure of 69 bar, inlet temperature of 260 degrees C and mass flow rates given in the table below. Single- and two-phase pressure drop measurements at 4.50 kg/s and 6.30 kg/s shall be performed twice: once with the low flow line and once with the high flow line.

The two-phase pressure drop tests shall be performed on the test bundle at 69 bar and an inlet subcooling of 58 kJ/kg. The single- and two-phase test matrices show the flow rates and bundle powers. Figure 2-8 to Figure 2-10 show the peaking pattern. For the two-phase pressure drop measurements, the bundle power shall not exceed 90 percent of the bundle critical power. The table below shows the total number of pressure drop measurements.

The overall pressure drop shall be measured by two separate devices with different measurement ranges to provide assurance that the measurements are correct.

A.3 STS-123.03 Requirements for ATWS-I Instability Tests A.3.1 Introduction and Summary The present specification defines the test hardware and test program for ATWS-I stability measurements for the U.S. Nuclear Regulatory Commission. It contains the definition of the test program, discussion of the test hardware, and documentation requirements.

The purpose of the measurements is to collect data for the stability performance of the bundle under natural circulation conditions to be used for subsequent thermal-hydraulic code validation.

The flow oscillation magnitude will be allowed to increase to collect cyclical dryout and rewetting data, without violating the loop safety limits.

The test bundle is a full scale mockup of a noncommercial 10x10 boiling-water reactor bundle design. It consists of a square array of rods supported at fixed axial positions by spacers. The bundle contains 81 full-length rods and 10 part-length heater rods that are 10.28 millimeters (mm) in diameter. A square cross section inner water channel occupies a 3x3 array with an outer dimension of 35 mm. The inner water channel has no internal fluid flow. The test bundle has a ceramic liner, which serves to simulate the flow channel and to electrically insulate the spacers from each other. The ceramics are housed in a stainless steel outer channel.

A.3.2 Stability Test Program The stability measurements to collect decay ratio and frequency data are taken under steady-state conditions and also under transient conditions with oscillating flow. The latter extends to large oscillation magnitudes such that cyclical dryout and rewetting and failure to rewet are observed. Some tests will be performed while a feedback module simulating neutron kinetics and pin conduction takes the inlet flow signal as input and provides a power demand signal as output. The following sections outline the projected test series; however, this test matrix may be modified during the actual tests to fit within the allotted time frame.

A.3.3 Range of Parameters The test matrix is created by varying the operating parameters in the following ranges:

Pressure: 7-8 megapascals

Subcooling: 20-45 Kelvin (K)

Flow rate: Natural circulation

Feedback Parameters: For the measurements with feedback module, the main decay ratio search parameter is the feedback gain representing a void-reactivity coefficient.

Subcritical reactivity and fuel thermal time constant will also be varied to test their effect.

A.3.4 Test Matrix without Feedback Module The table below gives the proposed matrix.

Test Pressure Inlet Subcooling Example Initial Power Water No. bar K megawatts Level 1 70 20.0 3.0 Nominal 2 70 20.0 3.0 Reduced 3 70 45.0 3.0 Nominal 4 80 20.0 3.0 Nominal Based on a specific initial power corresponding to a precalculated decay ratio of 0.5, for each test run, the power shall be increased in steps defined by Framatome GmbH.

A-5

A.3.5 Test Matrix with Feedback Module The table below gives the test sequences for the measurements with feedback for one subcooling point. Limit cycle amplitude limits are also indicated. The test sequences with feedback in the table below are repeated for the subcooling values 20 K and 45 K.

An initial state point will be established (i.e., pressure, subcooling, and initial power) and individual feedback parameters will be varied within that state point, as shown in the table below. The varied parameters are the following:

Remark:

The file SIN-123.03-T01.01 includes the parameters (Vrcmul, Rhosub, Tau) versus time also for the test SIN-123.03-T01.02. The reason is that the data acquisition was running consecutively without interruption for both tests.

Therefore, the left side displays for SIN-123.03-T01.01 and the right side displays for SIN-123.03-T01.2.

2101 Horn Rapids Road Richland, WA 99354 Division of System Analysis Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 T. Zaki, NRC Project Manager Natural circulation instability tests were performed in the Multifunction Thermal Hydraulic Test Facility KATHY in Karlstein, Germany. One type of test involved stepping up test assembly power in oscillating flow until failure to rewet occurs based on temperature observation. A second type of test introduced a simulated neutronic feedback to dynamically change the power, again with flow oscillations up to the point of failure to rewet. Two tests featured a transient inlet temperature. The largest flow oscillations in the test program ranged from ~ -7 kg/s to 13 kg/s. The tests varied system pressure (7 and 8 MPa), water level in the steam-water separator (0.4 and 1.1 m), and inlet subcooling (20 K and 35 K). These tests simulated a full-scale boiling-water reactor rod bundle. Before the dynamic instability tests, the rod bundle was characterized with single-phase and two-phase pressure drop tests. Steady-state critical power tests were also performed to characterize the conditions under which steady-state dryout occurs. This report describes the tests performed as part of this program.
