Ca/Pu substituted, single-phase zirconolite ceramics

Status

 
Terminated - Planned from September 2006 till September 2007

Goals

During this joint research project the behaviour of Pu within a ceramic wasteform will be studied, as well as the ceramic’s durability and surface interactions under hydrothermal conditions. The objective is to investigate the development of ceramic as a potential host medium for Pu disposition.

Expected results

With the growing quantity of surplus Pu in the world, a safe and durable method of Pu disposition is much sought after.

The results of this joint research project will increase the knowledge of a wasteform system that is not fully understood. Moreover, many of its implications can be applied to all wasteforms, whether they are meant for disposition of a single actinide species or for the ceramic immobilization of fission product waste. In addition, a comparison of the behaviour of actinide doped wasteforms with those doped with an inactive analogue will lead to improved models of wasteform behaviour based on simulant systems.
