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.

A 4667-second long discharge has been obtained in the ATF torsatron. The total amount of the energy input was 330MJ. The set-up procedures, the control of plasma parameters, and the effect on the wall conditioning for the long pulse discharge are reported in this paper. Fast density feedback control is not useful for a long-pulse operation; control of the neutral pressure on a slower time scale is necessary. Long-pulse discharges are quite effective for wall conditioning. Valuable experiences have been accumulated in the future experiments planned for LHD.
