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.

A prototype expert system, the NSSS-DS, is described. It is used for the diagnosis of three main systems—the rod control system, the reactor coolant pumps (RCPs), and the pressurizer—in the primary system of the Kori-2 nuclear power plant. This system diagnoses system malfunctions quickly and offers appropriate guidance to operators. The method of inference applied to this system is rule-based deduction with certainty factor operation. The diagnostic symptoms include alarms, indication lamps, parameter values, and valve lineup that can be acquired at the main control room. The application of this system to the rod control system, mainly consisting of electrical components, and the RCPs, mainly consisting of mechanical components, is described from the point of view of diagnostic strategies.
