Abstract:
Controlled-debris elements inhibit the formation of a fibrous/particulate debris bed that unduly increases the pressure head loss through the perforated plates of strainers in a nuclear power plant emergency core cooling system. In a loss of cooling accident, pumps draw cooling water through the plates, which retain on their surfaces fibrous material in the circulating water to prevent it from reaching the pumps while permitting entrained particulate matter to pass through the perforations. The controlled-debris elements have a specific gravity substantially the same as the circulating water so they are entrained in the cooling water that is drawn toward the strainers and intimately intermix with the fibrous and particulate matter in the cooling water. The elements are configured to provide open structures in the bed formed on the plate surfaces to distribute fibers in the flow away from the surface and maintain cavities between the elements for the particulates.

Claim (Index 1):
A plurality of controlled-debris elements adapted to be disposed in a nuclear power plant with a strainer located in a reservoir of water from which water is drawn for circulation to the reactor in response to a loss of cooling accident (LOCA), the strainer including at least one surface for retaining debris entrained in water in the reservoir flowing toward the strainer and perforations through the surface for permitting the water to pass through the strainer during a time period beginning near LOCA onset, wherein:\n each element has a specific gravity substantially the same as the circulating water during at least a portion of time following the LOCA onset for entraining the element in the flow of water in the reservoir toward the strainer and depositing on the strainer surface a debris/element layer comprising a plurality of the elements and the debris; and the elements are configured to form open spaces between adjacent elements in the debris/element layer.
