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.

In nonmechanical beam steering with phase conjugate (PC) mirrors, the scattered and reflected beams from a foam target are utilized. A scattering and reflection model has been made that coincides with the experimental results with an error between ±15%. In the case where four probe beams irradiated a foam target, the three-dimensional intensity distribution was simulated. The peak-to-minimum variation of the reflected plus the scattered energy per unit solid angle was [approximately]20% of the average energy.The PC beam direction needs to compensate for target motion (v [approximately] 300 m/s) to accurately irradiate an injected target with laser beams in the method of beam steering with PC mirrors. The compensation with four-wave mixing utilized as a PC mirror is shown. A PC beam can be adjusted by properly setting the angle between two pump beams.
