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.

Argonne to investigate Pu chemistry to aid Hanford cleanup
Researchers at the Department of Energy’s Argonne National Laboratory are investigating the details of plutonium chemistry with the goal of aiding the cleanup of the Hanford Site in Washington state. For more than 40 years, reactors located at Hanford produced plutonium for America’s defense program, resulting in millions of gallons of liquid radioactive and chemical waste.

Cascade is an ICF reactor concept with a flowing ceramic granule blanket operating at high temperatures (≤ 1600K). For electical power conversion, we examined three options: (1) conventional Rankine cycle using steam, (2) closed cycle Brayton helium gas turbine, and (3) the Field cycle, which is a hybrid Brayton/Rankine cycle using steam. We found the Brayton cycle to be the most suitable choice. The reference cycle chosen has a peak turbine nozzle inlet temperature of 1300K and a net efficiency of 54.8%. Reheats are an unnecessary complication which, in this case, do not increase efficiency. On the other hand, intercoolers between compressor stages are beneficial. Most of the components can be heat-resisting metal alloy, with ceramics needed only in a limited number of high temperature components. The Field cycle has both elements of the Rankine and Brayton, performance is somewhere in between, and steam pressures are lower than Rankine. Temperatures are high, but low enough to use heat resisting alloys everywhere. It is discussed here because it may be of value in reactors with gas-cooled blankets.
