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.”

Many divertor design studies for future fusion reactors rely on helium gas cooling. In these concepts, pressurized tubes or channels had to be operated at maximum temperatures between 1000 °C and 1300 °C while the lowest operating temperature is preset by the coolant inlet or by specific start-up and maintenance conditions. At such extreme temperature regimes, the only reduced activation material that would provide enough strength, paired with the necessary heat conductivity, is tungsten. Therefore, various tungsten materials and alloys are often publicized as candidate material for structural divertor applications.However, there are also clear limitations. Therefore, an intensive study on the influence of microstructure and chemical composition on the fracture behavior of industrially produced tungsten materials has been perfomed. This paper reviews the results and some other relevant properties of tungsten materials with respect to possible applications for structural divertor parts. Drawbacks and possible alternatives are discussed.
