Abstract
THIS PROGRAM DEALS WITH USING THE DIGITIZED VIDEO TDR LIQUIDLEVEL DATA PREPARED UNDER CONTRACT (NRC-04-84-146) OF THE MEMT-4 TEST FROM THE LOCA SIMULATION IN NRU PROGRAM. THESE NEW DATA AND TECHNIQUES WILL BE APPLIED TO ESTIMATE THE VOIDFRACTION, LIQUID LEVEL, AND LOCAL HEAT TRANFER CONDITIONS FOR THE OTHER NRU TESTS WHERE ONLY SELF POWERED NEUTRON DETECTORS (SPND'S) AND THERMOCOUPLE DATA ARE AVAILABLE. THE TECHNIQUE PRODUCES EXCELLENT RESULTS AND MAKE IT POSSIBLE TO MEASURE COOLING FRONTS, QUENCH FRONTS, FROTH ZONES, AND PROVUDE A QUALITATIVE ESTIMATE OF DENSITY. THE METHOD WILL BE USED TO EVALUATE VERY LOW REFLOOD RATES OOF .1 IN/S TO 1 IN/S (.25CM/S-2.5CM/S). TRANSIENT HEAT TRANSFER CONDITIONS FOR LOCAL TEMPERATURES WILL BE DETERMINED. THESE RESULTS WILL BE COMPARED WITH ELECTRICALLYHEATED TESTS WHICH DO NOT HAVE THE THERMAL RESISTANCE AND LOLOCAL POWER VARIATIONS OF NUCLEAR FUEL.
