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.

Neutronics and photonics analysis for UWTOR-M was carried out to assess radiation streaming effects on reactor performance. The effect the lithium enrichment in the Li17Pb83 breeder has on radiation streaming was investigated. Using an enrichment of 35% was found to yield an adequate tritium breeding ratio of 1.08 and an overall energy multiplication of 1.153. The bulk shield was optimized to reduce the radiation effects in the superconducting magnets with the limited shielding space available in the design. Detailed analysis for the radiation streaming into the divertor regions has been performed. The divertor targets were found to recover 91% of the streaming energy.
