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 adjoint gamma transport theory method is used to analyze the postaccident gamma detector data from the Three Mile Island Unit 2 (TMI-2) reactor lower head. It is concluded that there are two layers of materials at position L-11 of the TMI-2 reactor lower head. The lower layer contains predominantly nonfuel materials and the upper layer contains predominantly fuel. It is also concluded that 137Cs, 137mBa, 60Co, and 154Eu have the highest contribution to the detector signal. Finally, it is shown that the detector field of view is very small; hence, further evidence is needed to generalize these results to the remainder of the TMI-2 lower head.
