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.

This paper presents the results of iterative neutronics and thermal-hydraulic design optimization of a liquid metal cooled reactor for lunar surface power. The reactor placed below grade on the lunar surface is capable of generating 1.0 MWth continuously for ~20 years without refueling. It satisfies subcriticality requirement for shutdown, during launch and when submerged in wet sand and flooded with seawater in the unlikely event of a launch abort accident. The 3-D thermal-hydraulic design ensures good flow distribution and cooling of UN fuel pins and adequate mixing in the exit duct.
