NUCLEAR REACTOR FUEL ASSEMBLY

摘要

The invention relates to the nuclear energy industry. The technical result of the invention is the creation of a fuel assembly in which an assembly of in-core detectors can be mounted in the guide tube, thus increasing the representativeness of the measurement of the average combined temperature at the outlet from fuel assemblies, and increasing the safety of nuclear fuel use. A perforation is provided in at least one of the guide tubes of a nuclear reactor fuel assembly. The perforation in the guide tube may be situated either above the top spacer grid or above the top spacer grid and between the top two spacer grids.
