HAWTT Thermal Treatment Programme Tranche 3 MBGW Research and Development

Sellafield Ltd. (SL) have identified the potential for significant strategic and economic benefits associated with the thermal treatment of mixed beta/gamma solid wastes in comparison to the current baseline. The key perceived benefits from thermal treatment relate to the potential volume reduction and passivation of wastes, resulting in more optimised and fewer waste packages and by extension, reducing the future storage and disposal requirements. Consequently, SL would like to explore the capability and compatibility of thermal treatment technologies for mixed beta/gamma solid wastes.<br/>This Prior Information Notice (PIN) has been developed to aid in identifying thermal treatment technologies that are compatible with mixed beta/gamma solid wastes and to understand the capability of the supply chain to support these technologies. <br/>Through this PIN SL seek an understanding of;<br/>

• Identification of thermal treatment technologies that could be utilised in the treatment of mixed beta/gamma solid waste. <br/><br/>
• Determine the current level of technical maturity associated with the thermal treatment technology.<br/><br/>
• Understand the tolerance of thermal treatment technologies to various components of mixed beta/gamma solid wastes.<br/><br/>
• Understand the technical feasibility of the application of thermal treatment technologies against mixed beta/gamma solid wastes, based upon Learning from Experience (LFE) and technical limitations. Additional information: See attached
