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.”

A computer-aided design (CAD) import and tracking system, OiNC, has been developed that is currently being incorporated into the MONK and MCBEND criticality and shielding codes. The system enables analysts to take advantage of the advanced geometry modeling capabilities provided by the solid CAD modelers Autodesk Inventor and Solidworks. Various tracking acceleration techniques are implemented in order to reduce calculation time, including the full or partial automatic conversion of the CAD model to constructive solid geometry (CSG) form. For the criticality benchmark model detailed here, the overall calculation run time for a CAD-based geometry was found to be just 14% longer than an equivalent text-based CSG model. OiNC uses analytical surface descriptions, with full NURBS support, avoiding the approximations and problems associated with meshing. However, meshed models can still be imported and tracked, enabling shielding and criticality calculations to be performed, for example, on impact simulated finite element models.
