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.

To fabricate a tritium monitoring system with electrochemical hydrogen pumping attached, a tritium monitor system was constructed and assembled with a commercial tritium monitor and an electrochemical hydrogen pump using a proton conducting oxide. The hydrogen pump with CaZr0.9In0.1O3−α as the proton conducting oxide was operated at 973 K under electrolysis conditions using tritiated water vapor (HTO). The tritium molecules (HT) were extracted and controlled by the applied current over a range of two orders of magnitude. The tritium molecules have an advantage with respect to the tritium memory effect in the monitor because the tritium contamination is reduced. Next, a system feasibility test was conducted under various water vapor partial pressure conditions. Thus, the measurement of the tritium concentration via this proposed system was successfully demonstrated.
