Lattices with both ordinary water and light-heavy water mixtures are considered. The effects of volume fractions, plutonium concentrations, and heavy water fraction on the neutronics are studied through the use of computer calculations. A preliminary design for a D₂O-H₂O cooled breeder reactor is presented and the breeding characteristics of such a core are examined.iii, 166 leavesapplication/pdfenIn CopyrightLD5655.V855 1975.S84Thesis
