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.”

Oil-free reciprocating pump has been developed for tritium services at Tritium Process Laboratory (TPL) in Japan Atomic Energy Agency, and used for more than 20 years without any big trouble. One disadvantage of the above reciprocating pump is rather high ultimate pressure and drastically decreasing of the pumping performance at the lower suction pressure. The main reason would be that the check valves could not open enough at lower suction pressure, which are installed in the piston of the pump. In order to improve this disadvantage, solenoid valves option was tested instead of the check valves. Intentional opening & closing of the solenoid valves, linked with reciprocating motion cycle of the pump, improved more than one order of the ultimate pressure drastically. High evacuation performance was also demonstrated by the combination of molecular DRUG pump and the improved reciprocating pump with solenoid valve.
