Nuclear fuel body and process for making same
Abstract
Abstract POROUS NUCLEAR FUEL BODIES ARE MADE FROM A MIXTURE OF A THERMOSETTING RESIN, SUCH AS A PHENOL-ALDEHYDE RESOL RESIN OR A FURFURAL ALCOHOL RESIN, A CURING AGENT AND FUEL PARTICLES HAVING FISSION PRODUCT-RETENTIVE COATINGS. THE CURING AGENT IS NCLUDED IN AN AMOUNT AT LEAST ABOUT THREE TIMES THE AMUNT NORMALLY EMPOLYED TO COMPLETELY POLYMERIZE THE RESIN. THIS SUBSTANTIAL EXCESS OF CURING AGENT CAUSES CURING TO PROCEED RAPIDLY AND ENTRAPS GAS BUBBLES IN THE HARDENING POLYMER MATRIX. AFTER CURING, CARBONIZATION IS CARRIED OUT WHICH LEAVES THE COATED PARTICLES DISPERSED IN A POROUS CARBON MATRIX. FUEL PARTICLE COATINGS., PARTICULARLY PYROCARBON COATINGS, CAN FORM STRONG BONDS WITH SUCH THERMOSETTING RESINS. THE EXCESS OF CURING AGENT AVOIDS THE ESTABLISHMENT OF STRESSES IN THE COATINGS THAT MIGHT RESULT ULTIMATELY IN CRACKING.
