Remembering ANS member Gil Brown
Brown
The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.
Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.
Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”

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.
