This Idaho National Laboratory (INL) project involves the collaboration with Radiant Industries, Inc. (Radiant). Radiant is currently working toward deployment of Kaleidos, a helium gas cooled 3 megawatts thermal (MWth) microreactor, using tristructural isotropic (TRISO) fuel. Radiant plans to perform an irradiation experiment to inform fuel qualification and fuel safety criteria that will benefit deployment of the Kaleidos reactor design. The goals of the irradiation experiment are to provide irradiation performance data to qualify fuel for normal operating conditions, to support development and validation of fuel performance models, and to provide irradiated fuel and materials for post-irradiation examination (PIE) and safety testing.
