My Story: John L. Swanson—ANS member since 1978
. . . and in 2019, on his 90th birthday.
Swanson in 1951, the year of his college graduation . . .
My pre-college years were spent in a rural suburb of Tacoma, Wash. In 1947, I enrolled in Reed College, a small liberal arts school in Portland, Ore.; I majored in chemistry and graduated in 1951. While at Reed, I met and married a young lady with whom I would raise 3 children and spend the next 68 years of my life—almost all of them in Richland, Wash., where I still live.
I was fortunate to have a job each of my “college summers” that provided enough money to cover my college costs for the next year; I don’t think that is possible these days. My job was in the kitchen/dining hall of a salmon cannery in Alaska. Room and board were provided and the cannery was in an isolated location, so I could save almost every dollar of my salary.

In this paper we explore the use of dynamic mode decomposition (DMD) for modeling the kinetics of subcritical metal systems pulsed with fast neutrons. Our ultimate purpose is to obtain a fast and accurate reduced-order model for such systems that can be used to develop an emulator. An alternative to DMD is α-eigenfunction expansions, but we show that DMD is vastly superior in several ways for the systems of interest to us.
