Plasma Physics. Experimental measurements were made for the interaction between a neutral gas and a plasma moving relative to each other, and for a strongly inhomogeneous magnetic field to ascertain whether the plasma is heated when passing the inhomogeneity. Theoretical studies were made of a full- scale fusion reactor based on the principles of a rotating plasma and a strongly inhomogeneous magnetic field. Theoretical Reactor Physics. Summiaries are included of project calculations made for power and research reactors, heavy water reactors, and the Halden Boiling Reactor. Monte Carlo calculations and transport theory studies completed and in progress are outlined. Experimental Reactor Physics. Activities are discussed for work conducted: in the critical facility R-O; studies of fuels and lattices by successive substitution techniques; evaluations of R-3 fuel elements in the Production Development Pile at Savannah River; Zebra experiments; pressurized exponential experiments; determinations of the temperature coefficient of the resonance integral for uranium metal and oxide; measurements of resonance integrals of sodium, manganese, cobalt, copper63 and -65, zirconium, molybdenum-98, and thorium metal and oxide rods; studies of neutron slowing in graphite and heavy water around a fission source; control of the purity of UO/sub 2/ and Zircaloy-2 for R-3 fuels; fast-fission factors of UO/sub 2/ rods; and Dancoff-Ginsburg corrections for the resonance integrals of clusters of rods. Neutron physics studies are discussed for scattering of slow neutrons from H/sub 2/O and D/sub 2/O, testing of the mechanical neutron monochromator, measurements of the neutron spectra of the R-1 reactor, flux distributions in the R-2 core, thermal diffusion parameters of heptane, and the slowing down time of fast neutrons in water. An outline is given of work being prepared for the 5.5 Mev Van de Graaff accelerator. A discussion is presented of work in progress in the construction of electronic equipment for use ib the studies of neutron and reactor physics, and with the Van de Graaff accelerator. Numerical Analysis. A summary is presented of work completed and in progress for the Mercury computer, mixed reactor lattice calculations, reactor cell calculations, diffusion parameters, burn-up calculations, Monte Carlo methods, reactor kinetics, shielding studies, temperature distribution studies, uranium extraction from ores, and thermodynamic properties of D/sub 2/O.
