A polyphase tailored ceramic simulated waste consolidation form for ICPP type high Zr content high-level waste (HLW) calcines. The ceramic is specifically designed to provide chemically stable host phases for each species present in the HLW and to maximize waste volume reduction through high loadings and form density. The ceramic is designed for a 73 wt% waste loading with a density of 3.35 {plus_minus} 0.5(9/cm{sup 3}). The major phase in the ceramic is a highsilica glass, which contains the neutron poison boron as well as the majority of the non-refractory species in the waste. The primary crystalline phases are calcium fluoride, calcium-yttrium stabilized cubic zirconia, an apatite type silicate containing the plutonium simulant Ce, and a Cd metal phase. Minor phase include zircon, zirconolite, and a sphene type phase. Leach testing and microscopic analysis shows the ceramic form to chemically durable, with only the glass phase showing any detectable dissolution in deionized water at 90{degree}C.
