A series of eight small seed-and-blanket critical assemblies were studied at the Bettis Atomic Power Laboratory. Rod-type seed fuel elements which contained either /sup 233/U or /sup 235/U were utilized so that a direct comparison could be made between the lattice characteristics of the two fuels. Also, blanket regions which contained rod type elements with either natural ThO/sub 2/ or 1 w/o /sup 233/U O/sub 2/--ThO/sub 2/ were compared. The eight assemblies were of two principal types. The first type was a rectangular array having a central seed region surrounded by a wet blanket with a metal-to-water ratio of about one, and the second was a hexagonal array having a central seed region surrounded by a tightly packed dry blanket with a metal-to-water ratio of about 9.2. All experiments on these eight assemblies were conducted at 20/sup 0/C temperature. In addition, two of the wet blanket assemblies were studied in the High Temperature Test Facility at 480/sup 0/F and 650 psi. (NSA 22: 14262)
