Abstract: In accordance with the present invention, there is provided a strainer system for use in a nuclear sump. The strainer system of the present invention includes at least one primary strainer module which defines a primary strainer/filter surface. In the strainer system, the primary strainer surface of the primary strainer module has a debris interceptor which is cooperatively engaged thereto, and may be outfitted with one or more pressure released or activated membranes. In a loss of coolant accident, the debris interceptor, alone or in combination with the pressure activated membrane(s), is adapted to reduce the differential pressure experienced across the strainer system in nuclear power plants with medium to high fiber loads.

Abstract: A turbocompressor (1) has an electric motor (2), a multistage radial turbocompressor (3) and a common shaft (13). A section of the shaft (13) is formed as the armature (2b) of the electric motor (2) and a further section of the shaft (13) is formed as the rotor (3e) of the radial turbocompressor (3), with the rotor (3e) including a compressor shaft and compressor wheels (3b) connected thereto. A plurality of electromagnetic radial bearings (5) are arranged spaced apart in the direction of the shaft (13) for the journalling of the shaft (13), and a single electromagnetic radial bearing (5) is arranged between the armature (2b) of the electric motor and the compressor wheel (36). The electric motor (2), the radial turbocompressor (3), the shaft (13) and the radial bearings (5) are inside a common housing sealed gas-tight to the outside. The housing (6) consists of a plurality of part housings (6e, 6f, 6g) which are connected together.

Abstract: A turbocompressor (1) has an outwardly gas-tight housing (6) within which an electric motor (2) and a multistage radial turbocompressor (3) are arranged on a common shaft (13). For journalling the shaft (13), electromagnetic radial bearings (5) are arranged spaced apart in the direction of the shaft. A gas seal (19) surrounding the shaft (13) is arranged between the electric motor (2) and the radial turbocompressor (3) in order to seal off the electric motor (2) with respect to the radial turbocompressor (3). The electric motor (2) has an inner space (9b, 9c) which is connected in a fluid-conducting manner to an outlet opening (6h; 21) which passes through the housing.
