Amazon provides update on its Washington project with X-energy
A year ago this month, Amazon led a $500 million investment in X-energy, alongside Citadel founder Ken Griffin, the University of Michigan, and other investors. In addition to that financing, Amazon pledged to support the development of an initial four-unit, 320-MW project with Energy Northwest in Washington state.

A dual-energy photon attenuation technique provides a means of measuring void fractions in a flowing fluid. The mean void fraction determined by this method is in dependent of the fluid thickness. A comparison of the dual-energy method with the single-energy attenuation technique reveals that the assumption of a static refer ence void fraction in a dynamic voiding case is less severe with the dual-energy method.
