Waste tank scheduling for B and T Plants

Description: Prior to fiscal year 1955 waste tank scheduling for Separations Plants included the assumptions that T Plant would cease operations in March, 1955 and B Plant would nto be reactivated. At the beginning of the fiscal year these were changed to the assumptions that T Plant would operate through June, 1958 and B Plant, after reactivation, would operate July, 1955 through June, 1957. It has been necessary to alter waste tank scheduling accordingly. The letter of July 23, 1954, {open_quotes}B Plant … more

The Effects of Circular End Plates on the Lift, Drag, and Pitching Moment at Subsonic and Supersonic Speeds on a Modified Triangular Wing Having an Aspect Ratio of 2, a Taper Ratio of 0.33, and a 45 Degree Swept Leading Edge

Description: Memorandum presenting an investigation made of the effects of circular end plates on the aerodynamic characteristics of a modified triangular wing of aspect ratio 2 and taper ratio 0.33.

Self-Shielding Measurements in PPA-20

Description: From Introduction: "The self-shielding characteristics of a number of absorbers and of U-235 and U-238 have been investigated in PPA-20 (66°).
