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.

This paper presents considerations on basic requirements of fuelling, plasma exhaust and wall conditioning in ITER-EDA. In ITER-EDA, typical machine parameters are 1.5 GW of a fusion power and 1000 sec of a DT burn duration. Fuelling system consists of gas- and pellet injection systems. Maximum DT fuelling rate is 100 Pam3/s (pellet) to 500 Pam3/s (gas). Impurity gas(e.g. Ne, Ar) will be also injected to control divertor radiation loss. In plasma exhaust, designed value of total neutral pressure at inlet of pumping duct is 0.1 Pa to 10 Pa. Total net pumping speed of cryogenic primary pumps is about 300 m3/sec. In maximum, 90% of the regenerated fuel gases (H, D, T) from the primary cryopump will be directly back into the plasma. In wall conditioning, glow discharge cleaning (GDC) and electron cyclotron resonance discharge cleaning (ECRDC) are considered.
