LOFT DTT rake assembly design fluid loads (open access)

LOFT DTT rake assembly design fluid loads

The maximum fluid forces acting on the LOFT DTT Rake Assembly during steady state and LOCE modes of operation, were estimated and presented for the 5-inch equivalent break flow area. A total of six loading mechanisms for each of the two modes of operation were identified. The most significant mechanisms were determined and the resulting loads and frequencies were estimated. The significant loading mechanisms were the Karman vortex-induced alternating lift forces, the steady lift forces due to pipe elbow secondary flows, and the steady drag forces.

LLL mirror fusion program: summary. [Field reversal and tandem mirror] (open access)

LLL mirror fusion program: summary. [Field reversal and tandem mirror]

During 1976, new Mirror Program plans have been laid out to take into account the significant advances during the last 18 months. The program is now focused on two new mirror concepts, field reversal and the tandem mirror, that can obtain high Q, defined as the ratio of fusion power output to the neutral-beam power injected to sustain the reaction. Theoretically, both concepts can attain Q = 5 or more, as compared to Q = 1 in previous mirror designs. Experimental planning for the next 5 years is complete in broad outline, and we are turning attention to what additional steps are necessary to reach our long-range goal of an experimental mirror reactor operating by 1990. Highlights of the events that have led to the above circumstance are listed, and experimental program plans are outlined.

Corrosion and ESCA studies of uranium after exposure to an RF discharge (open access)

Corrosion and ESCA studies of uranium after exposure to an RF discharge

Corrosion of uranium in O/sub 2/ or H/sub 2/O atmospheres can be inhibited by first oxidizing the surface and then exposing it to organic vapors at temperatures near 400/sup 0/C. There is evidence that a polymeric material is formed on the surface and that it may be responsible for the corrosion inhibition. Polymer coatings can also be prepared using an RF discharge. This paper describes experiments in which uranium surfaces were exposed to an RF discharge and then evaluated as to their corrosion resistance and surface characteristics. Various plasma gases were used and in each case corrosion inhibition resulted. Samples for corrosion tests and ESCA/Auger examinations were prepared at the same time. The ESCA spectra reveal the formation of hydroxyl groups on uranium surfaces exposed to the RF discharges. Comparisons with corrosion tests suggest that a low surface hydroxyl concentration is associated with a low corrosion rate. The experiments reveal variations in both surface composition and corrosion reactivity which are related to the plasma gas used. These results are discussed in terms of possible reactions occurring between uranium and the RF plasma.
