FEASIBILITY STUDY OF NITRIDE FUEL CORE AND RECYCLE SYSTEM TOWARD SELF-CONSISTENT NUCLEAR-ENERGY SYSTEM

A concept of nitride core and recycling system in relation to SCNES(1) has been investigated and it has been found that the safety of intact core is enhanced by zero burnup reactivity and negative feedback at U LOF (Unprotected Loss of Flow) and ULOHS (Unprotected Loss of Heat Sin k). The self-actuating modules are examined so as to eliminate recriti cality of degraded core. The nitride core can employ transuranics-adde d fuels and burn long life radioactive fission products after isotope- separation of FPs. The enrichment of N-15 and the laser isotope separa tion seem to need about 2.4% of produced electric energy in the prelim inary evaluation. (C) 1997 Published by Elsevier Science Ltd.
