Abstract: A system for displaying electronic construction documents includes an enclosure having doors extending across an open side to define an interior volume that is sealable against infusion of dust and water, and a monitor panel extending across the width of the interior volume to define a back chamber between the monitor panel and a back panel of the enclosure. The system includes a purge air system in fluid communication with the back chamber and that is operable, when door are open, to draw in and filter air from outside the enclosure and establish a positive air pressure within the back chamber. The monitor panel includes a perimeter frame with a center aperture and a transparent pane extending across the center aperture for viewing an electronic display therethrough, and is angularly adjustable between a plurality of angled upright positions while maintaining the positive pressure within the back chamber.

Abstract: In a debris trap that may be used in an Emergency Core Cooling System of a nuclear power plant, the filter media is arranged to define both filtration and bypass flowpaths that are in fluid communication with one another. At least initially, each of the filtration and bypass flowpaths are open, and the filtration and bypass flowpaths have relatively low and relatively high head loss, respectively. The debris trap is operative so that flow through the debris trap may passively, and typically gradually, transition from the filtration flowpaths to the bypass flowpath in response to the filter media collecting increasing amounts of debris. More specifically, initially substantially all of the flow may be through the filtration flowpaths, and thereafter the filtration flowpaths may become substantially obstructed so that substantially all of the flow is through the bypass flowpath.

Abstract: A field access station for housing and protecting an electronic display system in a sealed compartment in a first configuration and in a positively-pressurized compartment having a controlled outflow flow of filtered air in a second configuration.

Abstract: A self-contained portable habitat apparatus may be used in a radiological environment. The habitat apparatus includes a outer container adapted for being portable and freestanding, and the outer container is outfitted to include a chamber structure within the outer container. The chamber structure at least partially defines in interior space for being occupied by one or more humans. The chamber structure may be adapted for attenuating gamma radiation. Regarding the chamber structure being adapted for attenuating gamma radiation, the chamber structure may comprise one or more liners and/or panels, such as structural insulated panels. The one or more liners and/or panels may comprise a flexible layer, and the flexible layer may comprise polymeric material and metal, wherein the metal is for attenuating radiation.

Abstract: A panel for functioning as a barrier to radiation includes at least one layer for restricting the passage of radiation, and the layer for restricting the passage of radiation may be a layer of silicone impregnated with metal, such as tungsten and/or iron. The impregnated silicone layer may be mounted to and supported by at least one other structure of the panel. For example, the impregnated silicone layer may be positioned between, and laminated to, other layers of the panel. In one embodiment, the impregnated silicone layer is positioned between foam layers of the panel to form a core, and the core is positioned between exterior layers of the panel. One or more exterior layers of the panel may be in the form of sheet metal or any other suitable structure.
