Deflection Equations for Various Loading of Circular-Arc Curved Beams (open access)

Deflection Equations for Various Loading of Circular-Arc Curved Beams

In analyzing stresses, deflections, and forces in piping and certain structural systems, it is useful to have a set of equations giving the deflections at any point of a curved beam in terms of the various loads acting on the beam. This technical report presents the deflection equations for a curved circular-arc beam of variable length. The cases treated include in-plane and out-of-plane bending due to forces and moments applied to the end of the beam in three principal directions, and uniformly distributed loads applied along the beam in these three directions. Deflections were calculated by the strain energy method using Castigliano's theorem.

Thorium oxide Slurry Falling Ball Viscometer : Final Co-op Report, Winter, 1957 (open access)

Thorium oxide Slurry Falling Ball Viscometer : Final Co-op Report, Winter, 1957

A falling ball viscometer under development at ORNL, employing a flow system and an electromagnetically operated dash-pot pump, was evaluated for possible use with aqueous ThO2 slurry systems under reactor irradiation. Interchangeable check valve inserts were designed and fabricated to investigate several pump designs. Magnetic flux concentrations which originally prevented circulation of the ferritic stainless steel viscometer ball through the electromagnetic pump were eliminated by substitution of iron-magnetic stainless steel inserts. Viscosity was correlated through a logarithmic plot of the dimensionless Reynolds number vs. Froude number with the ratio of ball diameter to tube diameter as a parameter. The relation is linear in the laminar flow region.

Operation of the Distillation Method for the Determination of Sodium Oxide in NaK During the Calibration of a Plug Indicator (open access)

Operation of the Distillation Method for the Determination of Sodium Oxide in NaK During the Calibration of a Plug Indicator

The distillation method (Argonne Sampler) for the analysis of sodium oxide in NaK was used to calibrate a plug indicator. The description of the equipment, procedure, and experiences with the Argonne Samplers are presented in great detail to aid future users of this method. Although this method is not very precise, it has been thoroughly checked out and is recommended as a standard means for sampling and analysis for oxide in liquid metal systems. (auth)

Possibility of Oxygen Depletion in Stagnant Uranyl Sulfate Lines (open access)

Possibility of Oxygen Depletion in Stagnant Uranyl Sulfate Lines

It is concluded that an excess of O2 must be added to the HRT fuel circulating stream in amounts sufficient to recombine the D2 in dead-end lines and serve as corrosion protection.

Observed Pressure Drop Across HRT Off-Gas Adsorber Units (Charcoal Beds) at Various Flows of Oxygen (open access)

Observed Pressure Drop Across HRT Off-Gas Adsorber Units (Charcoal Beds) at Various Flows of Oxygen

A plot of the pressure-drop data shows that the pressure drop through a single HRT off-gas adsorption unit is equal to 2.66 times the O2 flow (measured in liters/min at 70 F, 14.7 psia).

HRP Dynamic Slurry Corrosion Studies : Quarter Ending April 30, 1957 (open access)

HRP Dynamic Slurry Corrosion Studies : Quarter Ending April 30, 1957

The assembly of a second thorium oxide slurry corrosion test facility, loop BS, has been completed and 2010 hr of operation on slurry have been logged. This second test loop has proved satisfactory from an .operational standpoint. Corrosion data and operational observations are given for six thorium oxide slurry runs made at 300 C in 100A pump loops BS and CS. A new development model of the rotator for an in-pile slurry toroid is described.
