On January 20-22, 1998, ''AA Fest. A Symposium on General Circulation Model Development: Past, Present, and Future'' was held at the North West Campus Auditorium of University of California, Los Angeles, in honor of Professor Ako Arawaka. The symposium consisted of two-and-a-half-day technical presentations, along with a banquet in the opening evening and a reception during the poster session of the second evening.

A parametric study of the Spent Nuclear Fuel Project system capacity is presented. The study was completed using a commercially available software package to develop a summary level model of the major project systems. A base case, reflecting the Fiscal Year 1998 process configuration, is evaluated. Parametric evaluations are also considered, investigating the impact of higher fuel retrieval system productivity and reduced shift operations at the canister storage building on total project duration.

This Progress Report summarizes the activities of the APS Experimental Facilities Division (XFD) over the period 1997-98. The XFD personnel focused on supporting the Advanced Photon Source (APS) users from day-to-day operations support to long-term research and development (R&D) needs. The XFD personnel would like to proudly share their major accomplishments with the readers of this report.
