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 present status of the inertial fusion program is reviewed. The program has two major applications, one to military areas, the other to long-term energy needs. The near-term program is described by a 5-year program plan that coordinates research and culminates in a 1987 decision. The near-term program strategy is to build and operate the three new large facilities, ANTARES, NOVA, and PBFA II in order to maximize the physics data base needed to evaluate the driver-target requirements for ignition and higher gain. Low-cost driver technology will also play an important role in the 1987 program decision. Depending on the outcome of this decision, there is a succession of archetypical facilities and associated systems studies necessary to achieve goals for long-term energy needs through inertial fusion. These are briefly discussed.
