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.

Nuclear power plant (NPP) outage represents a major operational cost that must be minimized to sustain competitiveness in the US energy market. However, outage management can be challenging because myriad of interdependent activities may need adjustment over the course of the outage. We conducted a site vist to the Advanced Test Reactor at the Idaho National Laboratory and a literature review to identify general directions for innovations in interactive visualization for outage management. First, new approaches are needed to represent task and scheduling uncertainty to better support estimates of effort and cost overruns as tasks change during outages. This would allow staff to project the likelihood of overruns and reallocate resources as appropriate. Second, outage support software should facilitate visualization of resource constraints whether hard (e.g., regulatory requirements) or ‘soft’ (i.e., those with cost, morale, or other consequences). When responding to emergent issues or unplanned work, the outage staff must be aware of all potential alternatives (e.g., overtime, additional staff, deferrable tasks) and the short- and longer-term implications of each choice. Third, there is currently limited understanding of how best to support outage staff’s ability to simulate the impact of potential schedule adjustments in response to new or reallocated work. Graphical “what if” scenario depictions should be an important component of future visualization capabilities. To realize the potential of AOCC, interactive visualization for outage management must better support situation awareness, decision-making and planning.
