Research on Criticality Safety Design of Mixer-settler
-
Abstract
Mixer-settler separator is the widely used extraction equipment in spent fuel reprocessing plant. Sensitive Analysis of mixer-settler based on criticality safety is analyzed, including phase states, mixed state, phase interface and concentration distribution. And effect of the mixer-settler size on criticality safety is analyzed. Then the limiting size of mixer-settler is given which has adequate criticality safety allowance in a large range of plutonium concentration. This paper provides a reference for the design of mixer-settler.
