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 the current study, investigations are reported on the effect of pressure gradients on the optical properties of the window used in optical diagnostics of plasma. Window surface deformations due to pressure gradients (differences between the inside and outside pressures of a vacuum vessel) at the vacuum interface are monitored with a digital dial gauge. The effects of these surface deformations on laser beam propagation through the window are discussed in the context of optical diagnostics. Ultra-high-vacuum sealing of a large rectangular glass window with a metal assembly using a Helicoflex seal is also discussed.
