FUEL ASSEMBLY WITH COOLED GUIDE TUBES FOR A NUCLEAR REACTOR |
摘要 |
The invention relates to a fuel assembly with cooled guide tubes for a nuclear reactor. It consists of a bundle of parallel fuel tubes (1) held in a structure comprising spacer grids, guide tubes (6) and end plates. At least a part of the guide tubes (10) comprises a set of guiding surfaces (16) projecting towards the interior of the tubes (10) over the whole of their length. The projections (16) are formed by embossing of the wall of the tube (10) and permit the guidance of the rod of absorbing material which is moved in the tube and the provision of circulating spaces for the cooling fluid between the tube and the rod of absorbing material. The invention applies in particular to pressurized water reactors and to reactors with neutron spectrum variation. |
