Available in PDF, EPUB and Kindle. Book excerpt: Experiments are reported involving 25 deuterium oxide and three small water internal thermal columns (ITC), or flux traps, inside annular thoria-urania cores. The moderator and the radial reflect were deuterium oxide. Several different fuel densities were used. ITC's were as large as 104 x 104 cm. Radial activation plots indicated central peaks up to ten times the fuel zone average at the mid-plane, and five times the fuel zone maximum. Available fuel and facilities were used to obtain data for evaluation of computational methods, which were reported separately. The limited selection of fuel prevented optimization of experimental cores.
