Abstract
IN PHASE I AN IN-SIT METHOD IS PRESENTED FOR ELECTRICALLY HEATING EMITTERS OF MULTI-CELL IN-CORE THERMIONIC FUEL ELEMENTS (TFES). NUCLEAR HEATING IS NOT REQUIRED. THIS IS ACCOMPLISHED BY SUPPLYING PULSES OF ELECTRIC CURRENT TO MOMENTARILY BIAS THE COLLECTORS IN THE TFE WI A SEVERAL-VOLT NEGATIVE VOLTAGE. ELECTRONS ARE EMITTED FROM THE NOMINAL COLLECTOR VIA SCHOTTKY EMISSION AND HEAT THE EMITTER VIA ELECTRON BOMBARDMENT HEATING. NO OTHER KNOWN METHOD, OTHER THAN INSERTING THE TFE IN A NUCLEAR REACTOR, CAN BE USED TO TEST THE OPERATING CHARACTERISTICS OF AN IN-CORE TFE PRIOR TO REACTOR INTEGRATION.
