ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Using a 1-D particle code, we have analyzed characteristics of an Inertial Electrostatic Confinement Fusion device with external ion source which is added to enable low pressure operation. When the pressure becomes low, though neutron yield decreases, the decreasing amount is less than estimated from the decrease in background (target) gas density and it is confirmed that ions are accelerated efficiently with little energy loss through charge-exchange collision with background gas at low pressure. And when the pressure is lower than 0.05Pa, almost all injected ions reach to the cathode and it is expected that applying high geometrical transparency enhances accumulation of ion and enlarges neutron yield.
