A debris filter configured for a nuclear fuel assembly bottom end part includes a lower nozzle () and the debris filter () is supported by the lower nozzle (). The debris filter () has an inlet face (A) and an outlet face (B) opposed to the inlet face (A), and comprises at least one filtering section (D) that has a retention capacity that increases gradually or stepwise towards from the inlet face (A) to the outlet face (B).

Debris filter for a nuclear fuel assembly bottom end part and method of manufacturing such a debris filter

A nuclear fuel assembly for a boiling water reactor extends along a fuel assembly axis and includes a base including a lower tie plate, a head including an upper tie plate and a lift handle, a bundle of fuel rods extending axially between the lower tie plate and the upper tie plate, and a water channel extending within the bundle of fuel rods with axially connecting the base to the head such that the load of the base is transferred to the head via the water channel. The fuel assembly further comprises a tie rod extending between the base and the head. The tie rod is axially fixed to the base and connected to the head via a connection assembly comprising a stopping member configured to abut an abutting surface of the head for limiting a downward movement of the base relative to the head during lifting of the fuel assembly, in case of a breakage of the water channel.
