Claim 16:
17. A nuclear reactor, comprising:
a vessel;
a plurality of nuclear fuel assemblies forming a reactor core arranged in the vessel;
a support plate arranged in the vessel above the reactor core;
a plurality of thermocouple ducts arranged in the vessel and passing through the support plate through dedicated orifices;
support members provided to keep the thermocouple ducts in position, each support member being rigidly attached to the support plate, at least one of the thermocouple ducts being attached to each support member, each thermocouple duct inwardly receiving and guiding a thermocouple;
each support member including a foot rigidly attached to the support plate, a head to which the or each thermocouple duct is attached, the head being detachably connected to the foot, the foot of each support member being arranged laterally offset with respect to the dedicated orifices; and
thermocouple columns extending above the support plate, a plurality of the thermocouple ducts being positioned in each thermocouple column and leaving the column through peripheral openings.
wherein the head comprises a core and a cap removably connected to the core, the core and the cap delimiting a plurality of housings for receiving the thermocouple ducts, the housing being delimited between the core and the cap,
wherein the housings are delimited by grooves hollowed in the core, the cap including at least one arm closing the groove,
wherein the core has two vertical faces opposite one another, the grooves being arranged in at least one of the faces, the at least one arm having a surface pressed against the face in which the grooves are arranged.
