FAST-NEUTRON REACTOR CORE WITH IMPROVED REGENERATION GAIN AND INCREASED FUEL IRRADIATION LEVEL

摘要

In a fast-neutron reactor core, fertile segments (16) of an oxygen-absorbing material (uranium carbide or nitride) are intercalated in the fuel pin assemblies (10) between the fissile segments (15). Combustion characteristics are enhanced and corrosion of the cladding (11) is prevented.
