Title:

核燃料集合体のウォータロッドにおいて同位体を製造する方法及び装置

Document Type and Number:

Japanese Patent JP5727727

Kind Code:

B2

Abstract:

Example embodiments are directed to methods and apparatuses for generating desired isotopes within water rods (22) of nuclear fuel assemblies. Example methods may include selecting (S300) a desired irradiation target (110) based on the target's properties, loading (S310) the target into a target rod (100) based on irradiation target (110) and fuel assembly (10) properties, exposing (S330) the target rod (100) to neutron flux, and/or harvesting (S340) isotopes produced from the irradiation target (110) from the target rod (100). Example embodiment target rods (100) may house one or more irradiation targets (110) of varying types and phases. Example embodiment securing devices include a ledge collar (500) and/or bushing (501) that support target rods (100) within a water rod (22) and permit moderator/coolant flow through the water rod (22). Other example embodiment securing devices include one or more washers with one or more apertures drilled therein to hold one or more example embodiment target rods (100) in a water rod (22) while permitting coolant / moderator to flow through the water rod (22).
