Nuclear reactor loop for particulate radiation outside core

Claim 1

AN IRRADIATION PROCESS COMPRISING ACTIVATING FINELY DIVIDED FLUIDIZABLE SOLIDS IN A NEUTRON ACTIVATION ZONE BY IRRADIATION THEREOF WITH THERMAL NEUTRONS AT FLUX IN THE RANGE OF 10**8 TO 10**15 THERMAL NEUTRONS PER SQUARE CENTIMETER PER SECOND, SAID SOLIDS COMPRISING IN THE RANGE OF 5 TO 100 WEIGHT PERCENT OF AN ELEMENT HAVING AN ABSORPTION CROSS-SECTION FOR NEUTRONS ABOVE 1 BARN AND PRODUCING AN ISOTOPE THAT DECAYS WITH THE EMISSION OF NEUTRONFREE PARTICULATE AND GAMMA REDIATION, THEN FLOWING THE SOLIDS SO ACTIVATED INTO A CHEMICAL REACTION ZONE SEPARATE FROM SAID NEUTRON ACTIVATION ZONE, MAINTAINING SAID SOLIDS IN A FLUIDIZED STATE IN SAID CHEMICAL REACTION ZONE BY INTRODUCING INTO THE BASE THEREOF A FLUIDIZING GAS CONSISTING ESSENTIALLY OF A GASIFORM CHEMICAL REACTANT, CONVERTING AT LEAST A PORTION OF SAID CHEMICAL REACTANT IN SAID REACTION ZONE BY NEUTRON-FREE RADIATION FROM SAID SOLIDS, RETURNING SOLIDS FROM SAID CHEMICAL REACTION ZONE TO SAID NEUTRON ACTIVATION ZONE, RECOVERING SAID FLUIDIZING GAS FROM SAID CHEMICAL REACTION ZONE AND SEPARATING A PRODUCT THEREFROM.
