Abstract: An electrical adapter for temporarily tapping into an electrical circuit external to the adapter having a first fuse holder member capable of receiving a first fuse holder member of the electrical circuit external to the adapter and a second fuse holder member capable of receiving a second fuse holder member of the electrical circuit external to the adapter. The fuse holder members or other temporary electrical quick disconnect connectors may be connected by cables to a power outlet or may be connected by cables to bare wires that may provide power to another circuit when clamped to the bare wires. When connected to an electrical circuit external to the adapter, the electrical adapter provides a source of electrical power while the electrical circuit external to the adapter is maintained and independently operated.

Abstract: Apparatus for shielding an otherwise exposed upper portion of a radioactive reactor component disposed in a refueling pool of water having a depth less than the height of the component. A vessel with a top end wall, a side wall larger than the transverse size of the component is disposed over the exposed upper portion until the lower rim thereof is immersed in the pool and the top end wall and the side wall are in spaced relation to the upper portion of the component. Fluid, mainly air, is evacuated from the vessel to cause water from the pool to enter the vessel and provide a water level therein which is above the water level in the pool and between the component and the walls of the vessel. The vessel is reinforced to withstand the pressures caused by removal of fluid therefrom and is suspended by beams and legs, the latter being engageable with the pool walls.
