[1K09] Development of Fuel-selfsupplying Fast Reactor

(2) Characteristics study of simple core

*Kazuo Azekura1, Yoshitaka Naito1 (1. NAIS CO., INC.)

Keywords:lead-cooled fast reactor, metal fuel, one-zoned core, coolant-void reactivity, burnup

The lead-cooled fast reactor has a very hard neutron spectrum, which reduces reactivity and power distribution changes, leading to simplicity of CR operations. In this work, a simple one-zoned core has been studied to evaluate neutronic characteristisc such as the operation period, coolant-void reactivity and discharge fuel burnup.
