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.”

Corrosion and creep behavior of tubes fabricated of three German stainless steels have been studied in a 10 000-h test in a sodium loop at 873 and 973 K. The measured weight losses depend on the temperature and the oxygen content of the sodium. The results of metallographic examinations with respect to the formation of ferritic surface layers are in agreement with element concentration profiles obtained by analytical techniques. The stabilized stainless steels pick up carbon from the sodium even at 973 K although the carbon content of the liquid metal is in the range of 0.1 to 0.2 ppm. The measured carburization corresponds to the thermochemical data of both the steels and the liquid alkali metal. The creep rates of two of the steels are not influenced by the sodium, and the third material in the cold-worked condition shows an acceleration of the creep by a factor of 5. The different behavior cannot be explained by structural or chemical changes in the materials due to the action of sodium. Future examinations will clarify the different effects of sodium on the behavior of the slightly different materials.
