Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.

A parameter study of a proposed inertial fusion energy chamber is performed. A baseline case of a 6-m-radius chamber filled with 6 μg/cm3 of xenon is studied in detail. The maximum first-wall temperature is shown to be 1136 K with an overpressure of 5.83 &plus 10−3 MPa. A parameter sweep is conducted for the chamber by adjusting the first-wall radius from 4 to 14 m, changing the gas density and changing the fill gas from xenon to argon. The results set limits on the first-wall radius for different gases and densities. Analytic fits to simulation results allow their use in overall engine design trade-off studies.
