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.

The computer program CRASH allows the calculation of triaxial stress and strain states in the sheath of cylindrical fuel elements when creep or plasticity occur in the cladding material. Any creep or plasticity law may be used in the program and any type of external stresses and strains assumed. A short description of the program is given in the first part of this paper. Its second part deals with some applications: examples of plastic thermal ratchetting under cyclic conditions and creep of cladding due to contact pressure are presented. These few examples show that the CRASH program is a useful and flexible tool for the cladding design of fuel elements. Moreover, its calculation time is sufficiently small as to allow intensive parametric studies.
