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.

Depletion perturbation theory was developed within the framework of an advanced hexagonal nodal diffusion method. A similarity transformation method was used to compute the mathematical generalized adjointsfrom the corresponding physical system because it was more convenient to utilize the numerical algorithms and codes developed for solving the real system equations. The methods were implemented using the DIF3D code for the flux solutions and were applied to a sample problem using a hexagonal geometry lattice. In all cases, there was good agreement between the results of direct subtraction and the depletion sensitivities. This work indicates it is feasible to generate depletion sensitivities within the framework of advanced nodal diffusion methods.
