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.”

We have tested typical polymeric materials related to the water detritiation system to evaluate their contamination by tritiated moisture and water. The polymeric samples were exposed to 740-1110 Bq/cm3-gas of tritiated moisture with a 1kPa of H2O pressure at a temperature ranged 288 to 298K for various times up to 70 weeks. The other polymeric samples were immersed directly in 70000 Bq/cm3-liquid of tritiated water at a temperature ranged 288 to 298K for various times up to 52 weeks. After the test samples were exposed, the concentrations of tritiated water absorbed in the sample were evaluated by static leaching method. The exposure time to HTO moisture affected negligibly the concentrations of HTO absorbed in the samples. The immersion time in liquid HTO in contrast affected strongly the concentrations of HTO absorbed in the samples, due to penetration of HTO. Appropriate polymeric materials were clarified in the light of HTO contamination.
