1. INTRODUCTION

As part of the normal refuelling sequences, both new and irradiated bundles can beparked in the cross-flow region of the liner tubes. This situation occurs normally for a fewminutes (up to ten minutes). Occasionally, due to a fuelling machine malfunction, cross-flow maybe necessary for many hours. The fuel bundle which is subjected to the cross-flow should becapable of withstanding the consequences of cross-flow for normal periods, and maintain itsmechanical integrity ' ' .

The cross-flow endurance test was conducted in the CANDU-Hot Test Loop at KAERIfor an initial period of 4 hours. The test was completed on October 16. 1996 using a newCANFLEX bundle and ten filler bundles, built by KAERI. The inlet cross-flow region waschosen as the test location because the fuel vibration is more severe there due to less restraintfrom adjacent bundles.

After the test, the bundle must be undamaged and must meet the normal requirementsfor a new bundle. The bundle successfully met the acceptance criteria after the 4 hourcross-flow test.

2. TEST APPARATUS

2.1 Test Loop and Rig

Test Loop

The CANDU-Hot Test Loop is designed to simulate the channel conditions in aCANDU-6 reactor, and the loop design parameters are as follows:

- Flow rate : 95 kg/s- Design pressure : 17.3 MPa- Design temperature : 348 t- Fluid : Demineralized Water

The CANDU-Hot Test Loop consists of main loop system, feed and bleed system,make-up water treatment system, cooling water system, chemical system, and control and dataacquisition system" .

The test rig which is a CANDU-6 reactor channel consists of two feeder pipes, apressure tube and two end fittings. Each end of pressure tube is attached to the end fitting by arolled joint. The schematic of the test rig is shown in Figure 1. The pressure tube innerdiameter is 103.385 mm and is made of Zirconium-2.5 wt% Nb alloy'41. The inside diameter ofthe inlet and outlet feeder pipes is 2~14 inch (sch. 80), which are equivalent to feeders ofchannel L-5 which is the highest flow rate channel of CANDU-6 reactor.

2.2 Test Bundle

The CANFLEX test bundle (#KF9613) was fabricated by KAERI, based on Drawing No.CANFLEX-37000-l-l-GA-E Rev. 3[51. Each of the 43 fuel elements contains a controlled-lengthstack of natural UO2 pellets in a Zircaloy-4 sheath. A graphite inter-layer separates the sheathand the pellet to protect the sheath from fission product damage. End caps are resistancewelded to the sheath extremities to seal the element. End plates are welded to the end caps tohold the elements in a bundle configuration. Special buttons are attached to the elements byBeryllium brazing, at two planes to provide heat-transfer or CHF enhancement. Skewed, splitspacers are brazed to the adjacent elements at their mid-planes to ensure the desired minimuminter-element separations. The bundle is spaced from the pressure tube by bearing pads brazednear the ends and at the middle of each outer element.

2.3 Instrument and Measurement

Dimensional Measurements of the Test Bundle

The measurement items of the test bundle, #KF9613, are as follows:

- Inter-element gap (outer elements only)

- Element bow- Bearing pad height- End plate profile- Bundle weight and length

The description of the measuring instruments is summarized in Appendix A.

Measurement of the Loop Data

Test rig for cross-flow endurance test has two gauge-pressure transmitters and twodifferential-pressure transmitters. One of two differential-pressure transmitters is used tomeasure the pressure drop of inlet feeder to outlet feeder. The other is for flow meter. Twogauge-pressure transmitters measure the system pressure at the inlet feeder pipe. Alltransmitters were calibrated to offer the optimized measuring range for each measuring point(Table A-2 & A-3).

The Resistance Temperature Detector (RTD) is used to measure the systemtemperature. It is located on the inlet feeder pipe close to the test section.

Flow rate is measured by the orifice flow meter which has a differential-pressuretransmitter. A pressure drop across the sharp-edged orifice is used for the calculation of flowrate. The actual orifice meter and its piping in the rig was dismantled prior to the test and theorifice plate was found to be in good condition. Therefore, it is expected that the accuracy ofthe meter will be as given by the ASME equation, which is expected in this case to be within1% of measured flow rate .

HP 3054A data acquisition system is used to collect and process the signals from thetransmitters and sensors. It is composed of data acquisition and control unit, 100 nano-voltdigital voltmeter, Multi-Corn HP-processor, 386 personal computer and high speed line printer.The power line cycle integration period (sampling time) of DVM is set to 1/6 sec. Moredetailed information are provided in Appendix A.

3. TEST PROCEDURE

3.1 Test Conditions

The coolant conditions used throughout the test were as follows :

a) the mass flow rate : 31 kg/s

b) temperature : 266 Cc) pressure (inlet) : 11.0 MPa nominal

The coolant temperature is chosen to be CANDU-6 reactor inlet temperature , to simulate thesituation when the fuel becomes stuck under this condition; see Table 1 for test conditionsduring the test run.

3.2 Bundle Alignment and Loading

One CANFLEX test bundle and eleven filler bundles with a bundle spacer were loadedinto the rig to simulate the condition of normal refuelling as shown in Figure 1; the test bundlewas placed at the inlet cross-flow region. The filler bundles were placed in the channel exceptone filler bundle which was placed upstream of the test bundle. All the bundles were loadedwith their logo (Company Monogram) end plate facing upstream. The following steps werefollowed to load the bundles in the test rig:

- A reference line at 12 o'clock was chosen (Figure 2). This line is the teodolite verticalline defined on the left end view (logo end plate) of the CANFLEX fuel bundle designdrawing .

- The bundle spacer was loaded.The first filler bundle was loaded its reference line was oriented at 12 o'clock.

- The second filler bundle was loaded and its reference line was aligned 28° CW to thereference line of the first filler bundle.The other filler bundles were loaded according to the angles specified in Table 2.

- The test bundle at inlet cross-flow region was aligned with the first filler bundle.- The last filler bundle was aligned with the test bundle.

Table 2 shows the serial number, position and orientation of the bundles as recorded for thetest.

3.3 Testing

The test was done in the inlet cross-flow region for 4 hours under very conservativeconditions. The channel was closed up, filled with water, pressurized and subsequently warmedup. When the test conditions (31 kg/s, 266 °C. 11.0 MPa) were reached, a set of readings oftemperature, pressure, mass flow rate and rig pressure drops were recorded every 30 minutesduring the run (Table 1). Upon completion of the testing, the angular orientations of the testbundle and two filler bundles (bundle 11 & 1, see Figure 1) were checked, but the bundles hadnot rotated during the test. The test bundle was inspected, and the bundle dimensionalmeasurements (as described in the section 2.3) were performed.

3.4 Quality Assurance

The rig was set and operated according to the Hot Loop Test Operating Manual"1. Inaddition, the procedures were prepared and the test was performed in accordance with AppendixA of the Test Specification for this test .

Data Record

The data measured during the test are stored on hard-copy and 3.25 inch floppy disk(TR-CX401-CF). The electronic files in the floppy disk could be accessed by HP-BASIC in theMulti-Corn HP-processor. The dimensional measurements are stored in files DM-CF-00 (beforetest) and DM-CF-04 (after test). The "Test Plan" including test witnessing records are storedin the task number CX-400-01-MPP-V.

5. RESULTS AND DISCUSSIONS

The coolant path was through the inlet feeder to the annulus which is formed betweenliner tube and the end fitting body (Figure 1-a). The inlet feeder was inclined at 58°counter-clockwise (Figure 1-b). The length of annulus from inlet feeder to flow holes was 1638mm. The region of the test bundle exposed to the cross-flow was between 60 mm and 190 mmfrom the logo end (upstream), see Figure 1-c.

Test bundle was exposed to a cross-flow of 3.2 m/s from each of the 63 flow holes inthe liner tube. The bundle can face severe bearing pad or inter-element spacer fretting wear ina short time due to the vibrations of the bundle and its elements. As this situation occurs for afew minutes during the normal refuelling sequences, the test bundle must satisfy the acceptancecriteria described in section 4.0, after the cross-flow test. The dimensional measurementsperformed were: inter-element gaps (height of spacer pair), bow of the outer elements, bearingpad height, end plate profile, bundle weight and bundle length.

Visual Inspection

The 4 hour cross-flow test showed no visible damage or unusual changes to the testbundle.

Spacer Wear (Inter-element Gap)

If we assume that the spacer wear is half of the inter-element gap, the average wear ofspacer is 5.5% after the 4 hours run. The maximum wear observed was 12.2% between theelement #20-21 (Table 3). The global trend was that the spacer wear is uniformly distributed(Figure 3).

Element Bow

The elements were less bowed at position "X" (bearing pad at 12 o'clock) than position"Y" (Tables 4 and 5). At the end of the test, the trend of bowing at "X" position changed(Figure 4), but at "Y" position remained almost the same (Figure 5).

Bearing Pad and Pressure Tube Wear

The wear of the bearing pads was acceptably small and a maximum of 16 Urn wasmeasured (Table 6). Bearing pad wear occurred between the test bundle and liner or pressuretubes at elements *9, 10, 11, 12 and 13 (Figure 6). Wear marks were also observed on thepressure tube at the middle and downstream end.

Profile Measurements

The end plates of both marked and plain ends were measured for their perpendicularity,waviness and length variation (Tables 7, 8, and 9). The end plate profile, perpendicularity, andelement length variation were measured at the end of the test, and did not exceed the designlimits'51.

Bent Tube Gauge Test

The test bundle passed through the bent tube gauge under its own weight after thetest.

6. CONCLUSIONS

The cross-flow endurance test of the CANFLEX fuel bundle was conducted in theCANDU-Hot Test Loop at KAERI. The test was carried out at a water flow rate of 31 kg/s,temperature of 266 °C and inlet pressure of 11.0 MPa. After the test, no visible damage wasobserved on the bundle or pressure tube, and all the bundle dimensional measurements satisfiedthe acceptance criteria.

DATA ACQUISITION SYSTEM

HP 3054A data acquisition system is used to collect and process the signals from thetransmitters and sensors. It is composed of data acquisition and control unit (DA/CU).' 100nano-volt digital voltmeter, Multi-CornA ' HP-processor, 386 personal computer, and highspeed line printer. The power line cycle integration period (sampling time) of DVM is set to1/6 sec.

The components of the data acquisition system are shown below.

The data handling program, written in the HP-BASIC language, consists of a mainprogram and various subprogram including steam tables. The program converts raw datasignals from the sensors to the appropriate engineering units and calculates coolant properties,mass flow rate, hot flow area of channel, channel Reynolds number, and so forth.

2. INSTRUMENTATION

2.1 Dimensional Measurement

The items of dimensional measurements of the test bundle are as follows:

- Inter-element gap (outer elements only)- Element bow- Bearing pad height- End plate profile- Bundle weight and length

The calibration date, accuracy and serial number of the instruments are listed in Table A-l.

2.2 Pressure

Test rig for cross-flow endurance test has two gauge-pressure transmitters and twodifferential-pressure transmitters (Rosemount smart type[A "'). One of two differential-ressure transmitters is used to measure the pressure drop of inlet feeder to outlet feeder.The other is for flowmeter. The basic data of each differential-pressure transmitter areshown in Table A-2. Two gauge-pressure transmitters measure the system pressure at theinlet feeder pipe. The detailed data of gauge-pressure transmitters are shown in Table A-3.

2.3 Temperature

The Resistance Temperature Detector (RTD) is located on the inlet feeder pipe closeto the test section. It is inserted into a thermowcll on the inlet feeder pipe.

2.4 Flow Rate

Flow in the channel is measured using a flange-tap type, square edged orifice platelocated in the 4 inch piping. A Rosemount smart type differential-pressure transmitter (TableA-2) measures the pressure drop across the orifice plate. To calculate mass flow rate,system pressure and temperature signals are also used by the computer program.The orifice plate used to measure channel flow is an ASME square edged, concentric platewith a diameter of 5.663 cm. The orifice plate and associated orifice flange are installed inthe piping with a nominal inner diameter of 8.73 cm. Flange taps are used to measure theorifice differential pressure with a differential pressure transmitter. The actual orifice meterand its piping in the rig was dismantled prior to the test and the orifice plate was found tobe in good condition. Therefore, it is expected that the accuracy of the meter will be asgiven by the ASME equation, which is expected in this case to be within 1% of measuredflow rate.

Abstract (15-20 Lines)

As part of the normal refuelling sequences of CANDU nuclear reactor, both newand irradiated bundles can be parked in the cross-flow region of the liner tubes. Thissituation occurs normally for a few minutes. The fuel bundle which is subjected to thecross-flow should be capable of withstanding the consequences of cross flow fornormal periods, and maintain its mechanical integrity. The cross-How endurance testwas conducted for CANFI.EX bundle, latest developed nuclear fuel, at CANDU-HotTest Loop. The test was carried out during 4 hours at the inlet cross-flow region.After the test, the bundle successfully met all acceptance criteria after the '1 hourscross-flow test
