Room Temperature Water Studies of the Conical Bottom Slurry Core Vessel

Description: Water studies were performed on the conical bottom, bottom-polar inlet, core vessel to provide design information for the high-pressure model being installed in the 300SM loop. Maximum heat transfer coefficients are obtained in the conical portion of the core vessel when the inlet nozzle is inserted into the core up to the point of extension of the imaginary continuation of the top hemisphere. The flow rate in the by-pass of the 300SM loop was calculated to be 9.5to 11 gpm (7to 8 ft/ sec). The … more

F0020-AN IBM-704 THERMAL TRANSIENT ANALYSIS CODE

Description: An IBM-704 thermal transient analysis code, designated F0020 was developed to reduce transient test data for a single vertical, rectangular coolant channel. Modes of heat transfer to water at 2000 psia covered by this code include forced convection (turbulent flow), nucleate boiling, departure from nucleate boiling, partial film boiling, and film boiling. The code will accommodate a plate mesh, and associated heat generation weighting factors, of a maximum of 50 axial and 10 radial nodes. (auth) more

PWR CORE 2 MODEL STUDIES TO IMPROVE INLETPLENUM-CHAMBER MIXING

Description: In the course of the PWR Core 2 study program, studies to improve mixing in the lower plenum were carried out using a quarter-scale air-flow model. By use of vanes to form a strong vortex in the lower plenum, excellent lower-plenum mixing was obtained with only slight increase in pressure drop. For the studies relating to a 9-ft core design, the model core was extended downward 4 1/2 in. below the Core I position. The flow baffle used for this configuration extended below the four inlets, with … more

Hydraulic Instability of Reactor Parallel-Plate Fuel Assemblies

Description: The work on the hydraulic collapse or instability of flat plates was extended by considering flow redistribution and the effect of unequal friction drops in the deflected region of the channels. A general formula for the pressure distribution over a plate as a function of the plate deflection is derived. From this general formula, linearized formulas for small deflections are derived for the pressure distribution and the critical velocity. Graphs of pressure distribution for various assumed def… more

SOLAR WINDS

Description: It is suggested that corpuscular radiation is hydrodynamic expansion of the solar corona which is called solar wind. Arguments are presented for this expansion of the solar corona in terms of motion of the comet tail aurorae production, magnetic storms, and cosmic-ray effects on earth. The corona is taken to be isotherrnal out to an undefined distance (in multiples of the radius of the base of the corona) and from there it expands adiabatically until supersonic velocities are reached at infinit… more

Atmospheric Turbulence

Description: Some characteristics of turbulence near the ground can begin to be interpreted There is yet little information about others (even near the ground) such as spectra measured along the vertical lines, or cross spectra between two variables. Further, results of turbulence characteristics over water are few and confusing, and no information exists about the effects of cities and deserts. As we go aloft, our information about spectra becomes more scanty, although the general areas of large turbulence… more

PHYSICAL PROPERTIES OF NEUTRALIZED ZIRFLEX WASTE

Description: An investigation was made to determine the physical properties and flow characteristics of the neutralized slurry to assist in the selection of satisfactory transfer equipment and storage conditions. The neutralized Zirflex waste slurry contalns 20 vol.% rapidly settling solids. It can be transferred easily if the flow is in the turbulent condition, but agitation is needed during temporary storage. Pipe lines should be flushed with water after transfer of the waste slurry.
