Fuel assembly for a nuclear boiling water reactor

A fuel assembly for a nuclear power boiling water reactor including a fuel channel defining a central fuel channel axis, fuel rods, each having a central fuel rod axis, at least 3 water channels for non-boiling water, each water channel having a central water channel axis and each water channel having a larger cross-sectional area than the cross-sectional area of (the average) fuel rod. The fuel rods include a first group of full length fuel rods and a second group of shorter fuel rods. ... Westinghouse Electric Sweden Ab

Method of controlling pressure in a fuel rod

A method and a system includes controlling and monitoring the gas pressure in a nuclear fuel rod during filling of the fuel rod with a gas, and subsequent sealing of the fuel rod. The system includes a control unit and a length measuring system, which control unit is communicatively connected to the length measuring system. ... Westinghouse Electric Sweden Ab

Fuel channel for a nuclear boiling water reactor

A method of making a fuel channel for a fuel assembly for a nuclear power boiling water reactor includes providing at least one first sheet of a zr-based material of a first thickness, providing at least one second sheet of a zr-based material of a second thickness, which is less than said first thickness, assembling at least said at least one first sheet and said at least one second sheet, such that a fuel channel is formed and such that said at least one first sheet forms a lower part of the fuel channel and such that said at least one second sheet forms a higher part of the fuel channel and such that said lower part is joined with said higher part, wherein said lower part constitutes 20-75% of the length of the fuel channel. The invention also concerns a fuel channel and a fuel assembly.. ... Westinghouse Electric Sweden Ab
