20110084008 | INCREASED EFFICIENCY STRAINER SYSTEM - In accordance with the present invention, there is provided an increased efficiency strainer system which is particularly suited for use in the emergency core cooling system of a nuclear power plant. In certain embodiments of the present invention, the strainer system includes one or more strainer cassettes or cartridges, with each such cassette or cartridge including a plurality of strainer pockets disposed in side-by-side relation to each other. In these embodiments, multiple cassettes or cartridges may be assembled together to form a strainer module of the strainer system. The strainer pockets of the cartridge each define an inflow end. Within the cartridge, or the module including multiple cartridges, the inflow ends of one or more of the strainer pockets may be enclosed by an elastic metal membrane. When in a closed position, the membrane prevents liquid flow into the corresponding strainer pocket via the inflow end thereof. The membrane remains closed when only a low pressure load is exerted thereon, but is deflected or deformed into an open position when a high pressure load is exerted thereon. The movement of the membrane to its open position effectively opens the corresponding strainer pocket, thus allowing for the flow of liquid into the interior of the strainer pocket via the inflow end thereof. | 04-14-2011 |
20110084009 | INCREASED EFFICIENCY STRAINER SYSTEM - In accordance with the present invention, there is provided a strainer system comprising a plurality of strainer modules, each of which comprises multiple cassettes or cartridges assembled together in a prescribed arrangement.

Integrated into the plenum duct is a pressure released membrane (PRM) which is positioned so as to effectively isolate one of the strainer modules from the remaining active strainer modules included in the strainer system. The pressure released membrane is uniquely configured so as to facilitate the activation of the isolated strainer module when pressure across the plenum duct increases beyond a prescribed threshold. | 04-14-2011 |
