IRRADIATION TARGET RETENTION SYSTEM, FUEL ASSEMBLY HAVING THE SAME, AND METHOD OF USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an irradiation target retention device capable of being inserted into conventional fuel rods and assemblies. SOLUTION: Example embodiment devices may hold several irradiation targets for irradiation during operation of a nuclear core containing the assemblies and fuel rods having example embodiment irradiation target retention devices. Irradiation targets may substantially convert to useful radioisotopes upon exposure to neutron flux in the operating nuclear core and be removed and harvested from the fuel rods after operation.
