Popis: To address the low thermal conductivity of the ZrO2-based inert matrix fuel and the instability in water of the MgO-based inert matrix fuel, the dual-phase MgO–ZrO2 ceramics are proposed as a matrix for light water reactor fuel for actinide transmutation and Pu burning. It is envisioned that in a dual-phase system MgO will act as efficient heat conductor while ZrO2 will provide protection from the coolant attack. This paper describes results of fabrication, characterization and hydration testing of MgO–ZrO2 ceramics containing 30–70 wt% of MgO.
