Robin hired me into EPRI in November 2003, within a year of my PhD. His office was a few doors down from mine, although he was the Vice President of R&D at time time. One evening, when we were both working somewhat late, he called me into his office to discuss the Alloy 600 crack growth disposition curve on which he and John Hickling were working. The aggregate data was scattershot, spanning more than two orders of magnitude. "We are working with the best researchers in the world," he shook his head, "there must be something that we are not seeing"... When I received the invitation for his memorial, my mind flashed back to that conversation. I realized that I have been asking that question, in the context of my own work, ever since. Much of my work have focused on the application of atom probe tomography (APT) to complement transmission electron microscopy (TEM). I and some others who work on materials of the light-water-reactor primary systems are realizing that TEM was not showing us all that there was to see and that APT is providing important new observations Robin was right.
