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.

To evaluate the nuclear criticality safety in a typical nuclear waste storage tank, a study was initiated to measure the affinity of granular solids for plutonium, neptunium, and uranium from synthetic salt solutions and actual nuclear waste supernatant liquor. Granular solids such as activated carbon, hematite, and sodium phosphates, if present as sludge components in nuclear waste storage tanks, have been found to be capable of precipitating/sorbing actinides like plutonium, neptunium, and uranium from nuclear waste storage tank supernatant liquor.Our results show that the removal of plutonium and neptunium from simulants by tank solid sludge components may be due to the presence of the activated carbon and metal oxides. Thus, the potential may exist for the accumulation of fissile materials in nuclear waste storage tanks containing trace levels of these radionuclides during lengthy nuclear waste storage and processing.
