摘要： A method of removing the upper internals assembly from a nuclear reactor pressure vessel for refueling that simultaneously disconnects two or more of the in-core instrument thimble assemblies from the reactor vessel penetrations through which their signal cables extend. The signal cables are connected to the penetrations with an electrical connector that supports the two or more in-core instrumentation thimble assembly signal leads. Before the electrical connector is disconnected, water in the vessel is lowered below the connection so that the process is performed in a dry environment.

摘要： Disclosed are various torsional restraint systems (1000, 2000, 4000, 5000) for torsionally restraining a jet pump assembly (25), wherein the jet pump assembly (25) includes a riser pipe (30), a transition assembly (40) on the riser pipe (30), and a restrainer bracket (100) connecting a first and a second inlet mixer (50A, 50B) to the riser pipe (30). The torsional restraint system (1000, 2000) includes a first contact member (240, 440) operatively attached to a side of the jet pump assembly (25) and a second contact member (240, 440) operatively attached to the side of the jet pump assembly (25) and disposed from the first contact member (240, 440) such that the first and second contact members (240, 440) restrain the riser pipe (30) from rotating about a centerline of the riser pipe (30).

摘要： A nuclear reactor internal structure is provided wherein generation and promotion of object-downstream separating vortices are suppressed so that coolant (1) uniformly flows in a reactor core and pressure loss of flow of the coolant (1) is reduced so that the flow of the coolant (1) is stabilized. A lower connecting plate (30) arranged in a lower plenum (8) comprises a ring portion, in which an arcuate portion and a cut-off portion are alternately formed. An outer peripheral portion of the ring portion is asymmetric relative to a flow direction of main flow and also asymmetric relative to a separating flow generation direction. Also, a nuclear reactor internal structure comprising pumps connected to a coolant inlet nozzle (3), which have discharge flow rate performances different from each other, a flow guide (231, 241) arranged in a bottom portion of the lower plenum (8) and/or a radial connection portion of which outer peripheral portion is formed in a streamlined shape, is provided.

摘要： The invention concerns a method of repairing a vessel, in particular a core shroud, in a nuclear power plant, in particular a nuclear power plant with a boiling water reactor. According to the invention, a damaged vessel part which surrounds a vessel pin is removed from the vessel. A new part (1) is then inserted to cover the resultant gap and is shrunk onto at least one adjacent vessel part (2). The invention further concerns a nuclear power plant comprising such a vessel with a shrunk-on part (1).
