Initial Conditions for the Dynamic Pinch

Description: Abstract: "The experimental formation of the dynamic pinch has been an art based upon available electrical condensers, available glass and quartz tubing and an empirically determined gas pressure range. This report attempts to correlate some of this empirical information with the processes of ionization, insulator wall heating, magnetic field penetration, and shock hydrodynamics."

Preferential Pumping and Its Application to the P⁴ Experiment

Description: Report analyzing the "preferential removal of neutral gas from an incompletely ionized plasma in which the ionized particles are allowed to drift along magnetic field lines through a differentially pumped channel" and its relation to the P⁴ experiment. The report also analyzes the regenerative and non-regenerative losses of plasma by radial diffusion, as well as "considerations relating to the ultimate disposal of overflow plasma."

Dissociation of H₂⁺ by Photons

Description: Abstract: "A measurement was made of the dissociation of vibrationally-excited H2+ ions by photons having quantum energy in the vicinity of 4 e.v. The calculated cross section from theory is 3 x 10-(-18) cm-2. The experimental result is 10-(-17) cm-2; a factor of 10 uncertainty is present because the photon intensity was unknown by that factor."

Utilization of the Surface Tension of Liquid Metals in Making High-Vacuum Seals

Description: Abstract: "The free energy (surface tension) of a liquid film can withstand atmospheric pressure across a maximum theoretical gap of 10-(-3) cm between solids if the liquid wets and bridges the sides of the gap continuously. The eutectic alloy of Ga, lm and Sm is used for this purpose. This alloy is molten at room temperature with surface tension > 500 dynes/cm, vapor pressure < 10-(-8) cm at 500 C and excellent wetting properties. This alloy can be utilized in valves, motion seals, flanged joi… more

The Mechanism of Failure in Corona Discharge

Description: Abstract: "Experimental evidence is given which indicates that electronic bombardment is responsible for damage and failure of insulating material subjected to intense corona attack. The experimental revolts are further supported by some theoretical considerations of the energy-time properties of corona discharges."

Standby status report Hot Semiworks facility

Description: This report is written to provide information concerning the status of the Hot Semiworks facility as it is placed in stand-by on July 1, 1957. The plant was constructed in 1951 and early 1952. It vas operated on Redox type investigations until the last of 1953. The plant was then converted to the Purex flowsheet under Project CA 513 D. Operations on the Purex type investigations were started in early 1955 and continued until early in 1956. At that time a maintenance program for plant improvemen… more

Corrosion of 2-S Aluminum in Potassium Tetraborate Solution

Description: From summary: "A laboratory test was conducted to determine the feasibility of using an uninhibited solution of potassium tetraborate in steam condensate as a material for a pile ink facility. The evaluation was made from the standpoints of 2-5 aluminum corrosion, the rate and composition of film build-up on aluminum flow surfaces, and the change of solution composition."

Process tube boilout experiments

Description: The loss of cooling water from a Hanford production reactor has serious implications because of the accompanying reactivity transient. It is imperative that the time dependence of this transient be determined in order to evaluate properly some aspects of reactor safety. A previous experiment has been done however it was primarily in the nature of an exploratory run leading to the present experiment. The experiments described below cover a much wider range of conditions and have been used as a b… more

Re-evaluation of Ball 3X Recovery System improvements, 105-B, D, DR, F, and H

Description: Since the installation of Ball 3X equipment on the older reactors, several inadvertent ball drops have been experienced, many of which have required considerable recovery time. Furthermore, it is very probable that these recovery times be significantly increased subsequent to the proposed installation of air accelerated vertical safety rods. Because of this, interest has been expressed by reactor operations personnel toward provision of a ball recovery system which would substantially reduce th… more

Fuel element performance

Description: For some time, it has been considered that cycling natural uranium fuel elements through the {alpha}-{beta} transformation point (approx. 662 C) is a contributing factor in split type ruptures. This hypothesis is based upon the fact that the transition temperature, a one percent increase in volume occurs. It is reasoned that as the uranium hardens under irradiation, it becomes progressively less able to adjust to the severe stresses imposed by the volume change as the material cycles through th… more
