Abstract
A model of a ceramic breeding zone has been designed and manufactured for t esting in the IVV-2M fission reactor. The model contains both lithium ortho silicate and beryllium spheroid particles 1 to 2 mm in diameter. The struct ural material is ferritic-martensitic stainless steel. In addition, a mocku p of the model for verification of neutronics calculation methods has been designed and manufactured. A special facility (Functional In-Reactor Invest igations of Tritium-Breeding Models) has been designed, fabricated, and ass embled at the reactor for studying the kinetics of tritium extraction from the ceramic material under irradiation. Neutronic and thermohydraulic calcu lations and an initial measurement of tritium release from the model under reactor irradiation have been performed
