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.

Presently there exist no experimental methods readily available to characterize the comprehensive motion of wire-wrapped pins for the purpose of measuring fluid structure interactions. Specifically, the dearth of capabilities lies in the need to capture pin-to-pin interactions within the bundle that do not have visual access. This study leverages recent previous efforts that have demonstrated the successful use of a distributed strain sensor to characterize the motion of a single wire-wrapped pin under fluid flow and expands through the use of multiple instrumented pins to characterize the simultaneous motion of pin-to-pin interaction. The outcome of this study demonstrates the direct measurement of pin-to-pin contact, rubbing, and interaction over a range of relevant flow rates on a 19-pin wire-wrapped bundle.
