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 method is developed for obtaining information about reactor power shapes from readings of in-core detectors. The readings are used to determine the coefficients for an expansion of the space-dependent power in terms of a set of basis functions. A least squares approach ensures that all the detector readings contribute to the result. Test cases for one-, two-, and three-dimensional distributions show that accurate results can be obtained with a rather simple choice of basis functions.
