Abstract
Four He-bonded fuel pins containing uranium-plutonium mixed nitride pe llets were fabricated for the irradiation tests in JMTR, aiming at und erstanding the irradiation behavior and demonstrating the feasibility of mixed nitride as an advanced fuel for FBRs. Mixed nitride pellets w ere prepared by carbothermic reduction of the oxides. One of the fuel pins was fitted with a set of W-Re thermocouples in order to trace the temperature change of pellet center during irradiation. Moreover, fer ritic stainless steel was adopted as a cladding material in one fuel p in besides type 316 austenitic stainless steel. In this report, the de sign and characteristics of mixed nitride fuel pins are described.
