Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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 poloidal field (PF) power supply is an important subsystem of the EAST (Experimental Advanced Superconducting Tokamak as the device status detection and protection are essential. The PF power supply monitor system is based on the Experimental Physics and Industrial Control System and the human machine interface is the Control System Studio (CSS). The alarm is a plugin of CSS, used to help operators take correct action at the correct time. This technical note creates the alarm system, including server, client, Java Message Service interface, and relational database and configures the alarm attribute and sets the action for all variables that may trigger the alarm. When the alarm is triggered, the system goes into fault mode, the alarm server sends mail or pops up a window automatically to prompt operators, and some actions may be executed automatically to protect the device. Then operators solve the fault according to the guidance and the system returns to normal, realizing device status monitoring and protection in real time. The EAST experiment shows the alarm system has better function and stable performance.
