Abstract
A nuclear steam supply containment system employing prefabricated component supports that are surrounded by steel concrete forms and anchored to the floor liner of a nuclear containment. The prefabricated component supports extend through the concrete forms and a reinforce concrete slab cap to a support elevation for the component. A second inner steel concrete form can be employed to form an annular concrete channel through which the supports extend. The center of the inner form can be filled with a sand-like substance, radiation absorber material or concrete grout.
Claims15
A containment system for a nuclear reactor steam supply system with a primary component, the containment system comprising:
- a metal liner, having a floor, side walls and a ceiling, the metal liner surrounding the nuclear steam supply system and forming a hermetically sealed compartment when an access hatch in the liner is latched in a closed position;
- a component support leg having one end directly affixed to the floor of the liner and embedded in concrete, the component support extending substantially vertically to a first elevation at which a primary component is to be supported;
- and
- an outer metal form that surrounds the component support leg and contacts the concrete in which the one end of the component support is embedded, the outer metal form having one end affixed to the floor of the liner, the outer metal form extending substantially vertically to an elevation below the first elevation.
