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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

A study of computational/analytical neutronics and heat transfer has been carried out for different types of gas-cooled fuel bundle lattices that could be used for the sub-critical fertile/fissionable blanket of a cylindrical-geometry hybrid fusion-fission reactor (HFFR) with thorium-based fuels. The HFFR concept envisioned is one with a simple cylindrical geometry, using an anticipated variant of a magnetic mirror to confine a deuterium-tritium (DT) fusion plasma. The annular-cylindrical blanket is approximately 10 meters long and 2 meters thick, and is a repeating lattice of pressure tubes filled with 0.5-meter fuel bundles that are made of (233U,Th)O2, and refuelled continuously on-line, sharing technological features with pressure-tube heavy water reactors (PT-HWR) and the Advanced Gas-Cooled Reactor (AGR) in the U.K.. With a 2-meter thick blanket, the average fissile content in the blanket needs to be at least 2.5 wt% in order for the HFFR system to be self-sustaining in power.
