Abstract

The fabrication and quality control of Ni-3 wt.% U (93% ²³⁵U) alloy rods (diameter: 8 mm, total length: 8 m) used as a reference fission product source (RFPS) are described. This RFPs is needed for the calibration of the fuel element rupture detector which is used for the continuous monitoring of the delayed neutron activity in the primary sodium of the Super Phenix fast neutron reactor. Special care was taken to obtain a sufficient alloy purity, a bright surface finish and a homogeneous ²³⁵U content on the surface of the rods. Finally the usefulness of the RFPS in Super Phenix has been demonstrated.
