Keywords:Fast Reactor, Microstructure-Controlled Ceramics Neutron Absorbers, Control Rod Worth, Safety Improvement

Highly microstructure-controlled ceramics neutron absorbers were developed for improving safety of fast reactors. The control rod worth were evaluated using several compositions as parameter. It was confirmed that the effect of additives on control rod worth was negligible.
