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.

In the cooling water system (CWS), being infrastructure for large research facility, one of the important issues is the operation reliability, and then the minimizing of operation and maintenance costs. For optimum design, we studied the cooling loops for pulse and continuous operations of clients, volume and inside piping structure of storage tanks, two-step heat exchanger, safety devices and energy conservational operation of the CWS. During commissioning, the flow rate shortage due to increase of pump head by rise of client pressure drop was resolved as the operation of a stand by pump. The unexpected water pressure hunting occurred at an ion cyclotron ranges of frequency (ICRF) inlet port was stabilized by exchange of the starting system of motor and transfer of a constant flow rate valve from the water outlet port to the inlet port of the ICRF. We confirm that a polishing system, a first neutral beam injection cooling loop and a plasma facing component baking system can be stably operated in the upgrade step of clients. To improve the coefficient of performance and stability of operation in chiller, we will develop the new header, decreasing the gap of inlet temperature of cooling towers.
