Title: Statistical evaluation of process parameters affecting properties of ICPP ceramic waste forms

Abstract

A primary option to immobilize calcined ICPP High Level Waste (HLW) is to form a glass-ceramic by hot isostatic pressing (HIPing) of a calcine-additive mixture. Laboratory-scale testing indicates that the resulting glass-ceramic product containing as much as 70 wt% calcined waste is durable and well densified. Compounds present in the waste, such as zirconia and calcium fluoride are used to form crystalline phases which host most of the radionuclides. Materials such as titania are added to immobilize species including cadmium and chromium, and silica is added to form an amorphous phase which hosts alkali metals and boron in the waste as well as radionuclides not immobilized in the crystalline phases. However, the formation of these desirable properties in the product also depends on HIPing conditions which are determined by the control of process parameters. Thus the twelve-run Plackett-Burman screening design was applied in this laboratory-scale study to determine process parameters having statistically significant effects on product properties.
