Advanced MOX fuel pellets which has neutron absober at central axis have been studying to prevent re-criticality at CDA. Particle dispersibility in molten metal was examined through the experiment using alternative substances. In order to uniformly disperse the neutron absorber during fuel melting, an appropriate fuel structure was examined through evaluation tests using alternative materials, and material feasibility of the core fuel was evaluated.
