Experiments on Antiprotons: Cross Sections of Complex Nuclei

Description: Experiments are described that have been designed to measure separately annihilation and reaction cross sections for antiprotons of approximately 450 MeV on oxygen, copper, silver, and lead. A new and more luminous spectrograph has been built for this experiment. The antiproton cross sections a r e compared with total proton cross sections, and are found to be larger by a factor varying from 1.74 for oxygen to 1.39 for silver. Calculations based on the optical model give a reasonable connection… more

HRT-CP: Results of Solids Dissolution Tests

Description: A dissolution cycle in the chemical plant consists of refluxing with 10.8 M H2SO4 for 4 hours followed by refluxing for a like period with 4 M acid. In each of 3 tests in which 370 gram batches of simulated corrosion product solids were subjected to two dissolution cycles using 820 excess acid more than 99.6 of the solid material was dissolved (based on the amount of undissolved material collected). In another test using one dissolution cycle and 820 excess acid 99.5 of the solids material was … more

Experimental investigation of effects of moderate sideslip on the flow fields near a 45 degree swept-wing-fuselage combination at low speed

Description: The flow fields near a 45 degree swept-wing-fuselage combination at moderate angles of sideslip (plus-or-minus 8 degrees), as determined experimentally at low speed, are presented as variations with chordwise distance for various spanwise and vertical locations and angles of attack. The results indicated that for positions close to the fuselage (on and near the plane of symmetry) changes in the angle of sideslip caused large changes in the flow-field characteristics and particularly in the loca… more

THE ECONOMICS AND HAZARD POTENTIAL OF WASTE DISPOSAL

Description: The two most important considerations in the disposal of radioactive wastes are safety and economy. All other steps in the waste disposal complex must be tuned to accomplish these two goals. In general, the hazardous waste in the nuclear power complex affect the cost of the nuclear power reactor fuel cycle, the general environment since disposal must exclude radioactivity from the environment for over 500 years, the costs and/or methods of waste treatment including fission product utilization, … more

Interface Thermal Conductance of Twenty-Seven Riveted Aircraft Joints

Description: Note presenting testing of twenty-seven structural joint specimens of 2024-T3 and 2024-T4 aluminum alloy consisting of a T-stringer riveted to a 10- by 10-inch skin surface under simulated aerodynamic heating with no external loading applied. Rivet size and pitch were found to influence the conductance but the rivet materials tested had no observable effect.

Description of Ornl Pool Type Critical Facility

Description: The Pool Type Critical Facility (PTCF) is a low powered, highly eariched (90 to 95% U/sup 235/) ordinary light water cooled and moderated, beryllium oxide reflected assembly. It is generally similar to the present BSR at ORNL, the principal modification being that the grid plate is arranged to accommodate both ORR and BSR fuel elements. The PTCF is located in the northwest corner of the existing BSR pool. The 9 x 7 lattice provides 63 fuel, control rod, or reflector positions. (W.D.M.)

Irradiation Experiment on Aluminum Fuel Plates Containing a 48 Wt % Uranium - 3 Wt % Silicon - 49 Wt % Aluminum Alloy with 20% Enrichment in the U-235 Isotope

Description: Description of a planned test to evaluate the behavior of aluminum fuel elements, containing a 48 wt % U - 3 wt % Si - 49 wt % Al alloy, in which the uranium is enriched in theU-235 isotope at the 20% level. This alloy greatly minimizes fabrication problems associated with the binary 48 wt % U-Al previously tested.

Handbook of Structural Stability Part 2: Buckling of Composite Elements

Description: "The local buckling of stiffener sections and the buckling of plates with sturdy stiffeners are reviewed, and the results are summarized in charts and tables. Numerical values of buckling coefficients are presented for longitudinally compressed stiffener sections of various shapes, for stiffened plates loaded in longitudinal compression and in shear, and for stiffened cylinders loaded in torsion. Although the data presented consist primarily of elastic-buckling coefficients, the effects of plas… more
