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.”

Two numerical codes, TOUGH2 with the EOS5 module and CODE_BRIGHT, were compared in a confidence building effort for multiphase flow problems in a geological repository in Boom Clay, Belgium. A model study comparison between two codes was carried out through three numerical examples, including a one-dimensional hydro-gas (HG) case, a two-dimensional (2-D) axisymmetrical HG case with a constant hydrogen production rate, and a 2-D axisymmetrical thermo-hydro-gas (THG) case with time-varying heat and gas production rate. This numerical study of modeling the gas-driven migration of pore water under constant or time-dependent thermal conditions in two dimensions is based on the current Belgian multibarrier repository design for geological disposal of high-level waste. Comparison between numerical results demonstrates that the two numerical tools give sufficiently similar results in all three cases, thus providing evidence for the consistency of these tools in solving HG and THG problems in Boom Clay. The differences in the results obtained by the two modeling tools were also discussed.
