Abstract
A filter for separating particles from cooling water in a nuclear plant of light water model. The filter has an inlet end (2) and an outlet end (3) and allow flowing through of the cooling water in a flow direction z from the inlet end to the outlet end. The filter comprises a plurality of channels (5) extending mainly in the flow from the inlet end to the outlet end. Each of the channels comprise a first (6) channel section provided closer to the inlet end, a second (8) channel section arranged closer to the outlet end, and an intermediate section (7) provided between the first and the second channel section. The intermediate section (7) has an extension d2 in a direction x transversely to the flow direction, which is essentially larger than the extension d1, d3 of the first and the second channel section. The filter further comprises a separating member (9) arranged in the intermediate section. The intermediate section and the separating member are arranged so that at least one bent passage (10, 11) for the cooling water formed between the separating member and the wall of the intermediate section.
