A filter for separating particles from a cooling liquid in a nuclear plant is presented. The filter includes at least one passage with an inner surface, an inlet end and an outlet end, wherein the at least one passage is arranged to permit through-flow of the cooling liquid in a main flow direction (MFD) from the inlet end to the outlet end. The inner surface of the at least one passage includes at least one surface section having a structured surface forming a plurality of surface portions facing the main flow direction (MFD) of the cooling liquid and being arranged to catch the particles. Also, a fuel assembly for a nuclear plant, including a filter is presented.

Filter and a fuel assembly for a nuclear plant

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 comprise a first group of full length fuel rods and a second group of shorter fuel rods. The fuel assembly comprises at least 5 fuel rods which belong to said second group and which are positioned such that the central fuel rod axis of each of these at least 5 fuel rods is closer to the central fuel channel axis than any of the water channel axes of the water channels.

The fuel rods include a first group of full length fuel rods and a second group of shorter fuel rods. The fuel assembly comprises 3 or 4 fuel rods which belong to said second group and which are positioned such that the central fuel rod axis of each of these 3 or 4 fuel rods is closer to the central fuel channel axis than any of the water channel axes of the water channels.
