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.”

The fixed-bed adsorption processusing zeolite has been studied as one of the promising processes for the recovery of tritiated water in the field of nuclear fusion. In H2O-HTO binary systems, the difference in adsorption rate must be considered to obtain the isotopic distribution coefficient of tritiated water adsorbed on zeolite. The static method is probably the best approach to measure the distribution coefficient considering the difference in adsorption rate. In this study, the influence of framework SiO2/Al2O3 ratio ranging from 2.0 to 10.0 and of cations (K+, Na+, Ca2+) on isotopic distribution coefficient of tritiated water adsorbed on faujasite-type zeolite was systematically examined. The isotopic distribution coefficient of tritiated water between water adsorbed on zeolite absorbent was 1.1~1.4. The effect of framework SiO2 to Al2O3 ratio of the X/Y type zeolite on the isotopic distribution coefficient depended on the content of cation in zeolite. The framework SiO2 to Al2O3 ratio of the NaX/NaY zeolite had negligible effect on the isotopic distribution coefficient. The considerable effect of framework SiO2 to Al2O3 ratio was found in the case of KX/KY and CaX/CaY zeolite.
