Abstract: An electrical equipment cable trough system for use with electrical equipment panel installations and providing internal retaining members defining a cable way having a cable-insertion space extended between the upper and lower extremities of each panel. Additionally, U-shaped header troughs are attached to the upper extremity of each panel with U-shaped cross-troughs extending between parallel groups of abutting panels. The interrelation between adjacent header troughs and cross-troughs permit a single panel to be removed from a group while continuing to provide support for the interconnected conductors carried by the trough system.

Abstract: A method and apparatus are provided for using heat generated by absorption of radiation from nuclear waste materials to reduce the viscosity of petroleum products contained within a subsurface earth formation. The nuclear waste material is positioned in a salt water formation underlying the subsurface earth formation so that the radiation emitted by the material heats the salt water formation. Conduction and convection transfer the heat to the subsurface earth formation, raising the temperature and thereby reducing the viscosity of the petroleum products. To prevent radioactive contamination within the salt water formation, the nuclear waste material may be encapsulated in a material selected to absorb alpha and beta radiation.
