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.

Tank waste operations resume at Idaho’s IWTU
The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

For a practical air detritiation system, the effect of the residual tritiated water left on the silica was demonstrated. The residual tritiated water significantly reduced the detritiation factor of the air detritiation dryer. To maintain the detritiation factor more than 350, the space velocity lower than 140 h-1 should be selected for the design and the operation of an air detritiation dryer packed with silica gel. The HTO/H2O separation factor evaluated using a dryer with residual tritiated water was 1.17 on the average. Silica gel is superior to commercial molecular sieves in dehydration ratio at room temperature. Dehydration from silica gel was dependent on the accumulated amount of purge gas, independent on flow rate. Dehydration from silica gel showed a slight pressure dependency. Consequently, silica gel is a promising desiccant agent for air detritiation dryer.
