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.

With the formation and development of multi-area power system and the continuous increasing proportion of installed units, nuclear power plants (NPPs) are facing great pressure on multi-area interconnected power system regulation. The load following capability of generating units plays a crucial role in ensuring the operation safety and stability of both NPPs and power system. At present, advanced pressurized water reactor (PWR) has a certain capability of load following. Compared with traditional large single module PWR NPPs, multi module NPPs consisting of several small modular reactor (SMR) such as modular high temperature gas-cooled reactor (MHTGR), have remarkable differences in both process structure and operation characteristics, such as the sixmodular MHTGR plant HTR-PM600. To study and verify the feasibility and performance of HTRPM600 on regulating frequency and tie line power in multi-area interconnected power system, a dynamic modeling of multi-area interconnected power system is given firstly to simulate the power grid futures. Then a new control strategy is proposed on the existing unit coordinated control system. Finally, the numerical simulation is conducted and the results show that HTR-PM600 can control frequency and tie-line power well in the operation control of multi-area interconnected power system. At the same time, the operation indexes of HTR-PM600 plant also meet the requirements.
