Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

College students help develop waste measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Gas-turbine power conversion systems can have lower capital costs than comparable steam-turbine systems due to their higher power density. The recent commercialization of magnetic bearing systems for large turbomachinery now makes direct recuperated Brayton cycles the preferred power conversion choice for gas-cooled reactors. This paper presents a multiple-reheat closed gas cycle optimized to use energy input from liquid-metal or molten-salt coolants with temperatures as low as 550 to 650°C. By utilizing reheat, these molten coolant gas cycles (MCGCs) have the potential for substantially higher thermal efficiency than current gas-cooled reactors if used with comparable turbine inlet temperatures. The MCGC system also eliminates the need for steam generators, which removes the potential for chemical reactions between the molten coolant and steam, and greatly simplifies the control of tritium for fusion energy systems.
