| Abstract: | 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 ULOF (Unprotected Loss of Flow) and ULOHS (Unprotected Loss of Heat Sink). The self-actuating modules are examined so as to eliminate recriticality of degraded core. The nitride core can employ transuranics-added fuels and burn long life radioactive fission products after isotope-separation of FPs. The enrichment of 15N and the laser isotope separation seem to need about 2.4% of produced electric energy in the preliminary evaluation. |
