The Babcock and Wilcox Company, Duke Power Company, and the U.S. Department of Energy are participating in a program to develop and demonstrate an advanced fuel assembly design incorporating UO/sub 2/-Gd/sub 2/O/sub 3/ for extended burnup in pressurized water reactors. In addition to the UO/sub 2/-Gd/sub 2/O/sub 3/ burnable poison-fuel mixture, the advanced design incorporates annular pellets, annealed guide tubes, Zircaloy grids, and removable upper end fittings to improve fuel economy and increase assembly burnup capabilities. This report, covering March through September 1981, is the first semi-annual progress report for the program. The physics model that will be used to design and license the UO/sub 2/-Gd/sub 2/O/sub 3/ assemblies has been developed and verified against data from the irradiation of previous demonstration UO/sub 2/-Gd/sub 2/O/sub 3/ assemblies. The assembly radial powers predicted using this model agree to within 1% of those actually measured in the demonstration assemblies. Further, a process to fabricate the UO/sub 2/-Gd/sub 2/O/sub 3/ fuel has been developed.
