Tests on Models of Nuclear Reactor Elements - Studies of Diffusion

Description: To estimate the distribution of temperature in the proposed nuclear reactor, one must determine a coefficient of eddy diffusivity and devise a suitable method of computing the heat transfer. Measurements of diffusion in a model of a blanket element for the proposed reactor indicated a gross eddy diffusion coefficient of about 0.002 (? .0005) ft{sup 2}/sec. Thus, the apparent eddy diffusion for the test conditions is about 200 times the molecular diffusivity of water and about. twice that of the… more

Spallation-Fission Competition in Heaviest Elements; TritonProduction

Description: Stacked f o i l s of Au{sup 197}, Th{sup 232}, and U{sup 238} were bombarded, i n a series of experiments, with 48-Mev helium ions, 24-Mev deuterons, and 32-Mev protons. Tritium from each f o i l was collected and then measured by a gas-counting technique. The qualitative r e s u l t s indicate t h a t high-energy t r i t o n s are emitted i n r e l a t i v e l y large abundance from a l l targets and with each of the bombarding p a r t i c l e s . Cross sections f o r t r i t o n production fr… more

The Sodium Hydroxide-Sodium Oxide-Sodium-Sodium Hydride-Hydrogen System

Description: Sodium hydride dissolves in and reacts with molten NaOH to give an equilibrium mixture of NaH, NaOH, Na/sub 2/O, Na, and H. In the case where there is a gaseous phase (hydrogen) and only one condensed phase, the system is defined by the temperature, pressure, and one composition variable. The equilibriu, H/ sub 2/ pressure, which is a measure of the H/sub 2/ activity within the melt, was determined as a function of the composition of the condensed phase(s) at 600, 700, and 500 deg for equilibri… more

On the Operator Approach to the Problem of Stability of Difference Schemes and the Convergence of Certain Iteration Procedures

Description: A number of considerations related to the stability of certain difference analogs of the differential equation of heat conduction and with the convergence of iteration procedures derived from implicit difference equations are presented. The operator approach is used in a manner which dispenses with the knowledge of eigenvalues. (J.R.D.)

THE SODIUM HYDROXIDE-SODIUM HYDRIDE SYSTEM

Description: Portions of the NaOH-NaH phase diagram were studied by means of differential thermal analysis. Under certain conditions NaH will either react with NaOH according to the equation NaH + NaOH in equilibrium Na/sub 2/O + H/ sub 2/ or thermally dissociate according to the equation NaH in equilibrium Na + 1/2 H/sub 2/. Both of these reactions are suppressed by a high H/sub 2/ pressure; and NaH neither reacts nor dissociates to an extent sufficient to affect the results reported. This was evidenced by… more

Electronic Specific Heat of Sodium Tungsten Bronze

Description: The design and operation of a calorimeter for use in the temperature range 1.8 to 4.2 deg K are presented, and the methods used in the treatment of data and calculation of results are discussed. The heat capacities of several Na- W bronzes (Na/sub x/WO/sub 3/) were determined in the temperature interval 1.8 to 4.2 deg K. Samples having x equal to 0.89, heat capacities are described adequately by the sum of two terms, one linear and one cubic in temperature. The electronic specific heat of each … more

Flow of an Aqueous Slurry Through a Vertical Tube

Description: The upward vertical flow of a slurry was investigated utilizing photographic techniques with the intention of obtaining data on solid phase concentration and velocity distribution and to evaluate the use of photography as a tool in slurry analysis. An annalytical expression for tbe ratio of the specific weight of the mixture in tbe tube to the specific weight of the mixture discharged was derived and used to verify certain assumptions indicated in the photographic study.
