Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

Several preconditioning techniques were applied to the power method, in conjunction with a symmetric variational acceleration strategy, to facilitate solution of reactor problems. First, the drawbacks in an approximate inversion were corrected by fitting an error recovery term to the power method. Second, a variational extrapolation technique that does not require knowledge of the dominance ratio was introduced. Validation results are reported for the International Atomic Energy Agency two- and three-dimensional benchmarks and for a two-dimensional pressurized water reactor representation.
