Cloud-Chamber Effect in Large Explosions

Description: Report discussing the atmospheric conditions under which a cloud of water droplets will form when an atomic bomb or a large amount of TNT is detonated. A theoretical discussion of the conditions is presented followed by a discussion of two experimental verifications of the theory, including the July 16, 1945 nuclear test at the Trinity site in New Mexico.

Delayed Neutrons from [Uranium-235] After Short Irradiation

Description: Report discussing the decay curve of delayed neurons from U²³⁵ after very short neutron irradiation of about 10-milliseconds in duration following a drop experiment that resulted in the production of a neutron burst. The experiment arrangements and results are presented in graphical and narrative form. Tables and graphs plot measurement of decay from 0.2 seconds to 10 minutes following the drop.

SUVIUS: A Circulating and Plateout Activity Program for Gas-Cooled Reactors With Arbitrary Radioactive Chains

Description: Report describing a time-dependent method for estimating the fuel body, circulating, plateout, and filter inventory of a high temperature gas-cooled reactor (HTGR) during normal operation. This method has been implemented in the SUVIUS computer program, which is also described in the report. The program structure, including role and function of subroutines, program flow, input instructions, machine requirements, and algorithmic validation, is described and a test problem is included.
