Status and Progress Report for Thorium Fuel Cycle Development for Period Ending December 31, 1963

ThO2-based pellet fuels - their properties, methods of fabrication, and irradiation performance: a critical assessment of the state of the technology and recommendations for further work

“…National Laboratory conducted a series of tests (Wymer and Douglas, 1965, 1966a, 1966bLotts, 1969a, 1969b) in the Materials Test Reactor (MTR). Engineering Test Reactor (ETR), the Chalk River National Research Experimental Reactor (NRX), and the Oak Ridge Research Reactor (ORR).…”

Preparation of Thoria and Mixed-Oxide Microspheres

“…Little information is available, however, concerning the effect of surface on the composition of the product obtained, even though Knox (8) has postulated that minor products are formed on the walls of the reactor vessel. Factors indicated to be important in controlling surface effects include the material of construction for the reactor (79); coating, such as salt, applied to the inner surface of the reactor (6, 13, 17); "aging" of reactor by repeated oxidations (5,6,11,17,18); and the amount of surface or the surface-volume ratio of the reactor (15, 16).…”
