Buildup and Decay Factors for Members of the U-232 Decay Chain
Activity ratios for the important members of the U/sup 232/ chain are presented in tabular form. These ratios are presented for initially pure U/sup 232/, initially pure Th/sup 228/ and initially pure Ra/sup 224/.- (auth)

Quarterly Report of the Solution Corrosion Group for the Period Ending July 31, 1958
6 6 5 4 ; 6 6 5 6 4 8 4 : the chemica: stability of possible fuel solutions, and the results obtained from these runs have been compared with data obtained by others. A solution containing 0.04 m UO/sub 2/SO/ sub 4/, 0.03 m CuSO/sub 4/, 0.03 m NiSO/sub 4/, and 0.023 m D/sub 2/SO/sub 4/ in heavy water was not completely stable at 175 deg C or at other higher temperatures. About 7% of the copper was lost at 175 to 275 deg C, and an additional 9% was lost when the temperature was increased to 300 deg C. In the same solution the nickel solubility decreased by 40% up to 200 deg C and then increased up to 275 deg C and at 300 deg C again decreased. Throughout the run no uranium was lost from solution. A second solution containing 0.01 m UO/sub 2/ SO/sub 4/, 0.02 m D/sub 2/SO/sub 4/, 0.01 m CuSO/sub 4/ and 850 ppm nic kel in heavy water was stable at 300 deg C. However, when an additional 450 ppm of nickel was added to the solution, about 10% of the uranium, 6% of the copper, and 20% more nickel …

Experimental Investigation of Flutter and Divergence Characteristics of the Rocket-Motor Fin of the ASROC Missile
Report presenting testing of models of rocket-motor fins of the ASROC missile for flutter and divergence in the supersonic flutter tunnel for a range of Mach numbers. Results indicate that both divergence of the overhung leading edge and flutter occur within the sea-level operating conditions of the missile at Mach numbers above 1.0. Results regarding the flutter boundary, type of flutter encountered, possible solutions to flutter problems, and possible effects of nondestructive type of flutter are provided.

ULTRA HIGH FLUX RESEARCH REACTORS
Verbatim transcriptions of nine seminars on ultra high flux research reactors are revised and collected here. The seminars included: production of transuranic elements, isotope production using high fluxes, high fluxes for neutron diffraction experiments and velocity selector experiments, solid state physics and the materials for high flux reactors, physics of flux-trap and other ultra high flux reactors, and design considerations of aqueous flux-trap reactors.
