Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

The IGNIR collaboration between Italy and Russia is centred on the construction of the core of the Ignitor machine in Italy and its installation and operation within the TRINITI site (Troitsk, Russia). A Preliminary Safety Report is under preparation for the siting of the Ignitor experiment in Troitsk. A specific site has been selected, with characteristics determined from informations regarding TRINITI. This site has many positive characteristics, such as the presence of electrical facilities because of nearby distribution nodes, and the full availability of the required room for the arrangement of all Ignitor buildings. The results of the analyses, both regarding doses to population and personnel, and other environmental impacts, show that the TRINITI site in Troitsk is a consistent choice for Ignitor localisation, according to the safety and the environmental impact point of view.
