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 study deals with the processes of converting trace CH4 in the oxidation reaction and adsorbing H2O. The conversion of CH4 was confirmed at various reaction temperatures and flow rates by injecting O2 above the equivalence ratio of CH4 in Ar. The conversion was higher at a higher reaction temperature and a lower flow rate. Also, the impurity effects of CO2, CO, and H2O coexisting in the feed gas with CH4 were investigated. When CO2 and H2O were included in the feed gas, CH4 conversion was decreased, and CO contained in the feed gas increased CH4 conversion by the heat of oxidation reaction. When CH4 is converted to CO2 and H2O through oxidation and H2O is adsorbed on the adsorbent, complete recovery of hydrogen isotopes can be obtained. Molecular sieve was used as the adsorbent, and the water adsorption capacity of the adsorbent was confirmed by generating water through the generator. Finally, it was confirmed that converted H2O from CH4 was adsorbed on the absorbent.
