Process Considerations for Hot Pressing Ceramic Nuclear Waste Forms

摘要

Spray calcined simulated ceramic nuclear waste powders were hot pressed in graphite, nickel-lined graphite and ZrO sub 2 -lined Al sub 2 O sub 3 dies. Densification, initial off-gas, waste element retention and pellet-die interactions were evaluated. Indicated process considerations and limitations are discussed. 15 figures. (ERA citation 06:026902)
