Device for supplying a feedstock liquid

摘要

This invention provides a device for supplying a feedstock liquid comprising a light irradiator for irradiating with light drops of a feedstock liquid that includes uranyl nitrate, the drops being dripped from a dripping nozzle device wherein the dripping nozzle device comprises dripping nozzles and the drops are dripped from each of the dripping nozzles; and flow regulators, each of which controls an amount of the feedstock liquid to be supplied to each dripping nozzle from a feedstock liquid reservoir in which the feedstock liquid is stored, depending on conditions of the falling of the drops irradiated with the light.
