A measurement core for measuring nuclear heating, the core extending in a longitudinal direction and having a main plane, includes at least: a first layer of material, forming a first sample; a first thin layer of electrical insulation on the first sample; a thin conductive layer forming a heating electrical resistor on the first layer of electrical insulation; and a second thin layer of electrical insulation on the heating electrical resistor. A calorimetric sensor includes: an outer jacket; a gas contained in the jacket; a measurement core disposed in the jacket; a link for holding the core in the jacket and transferring the heat between the core and the jacket; and temperature measurement capable of measuring the temperature at a hot point, and the temperature at a cold point.

A sample holder for the measurement of nuclear heating in a nuclear reactor, comprises: a body configured to contain a heat-sensitive sample along a longitudinal axis; and means for removing heat from the body to the exterior of the sample holder, wherein the means for removing heat from the body to the exterior of the sample holder comprise: a peripheral structure located on the periphery of the body; and a central structure mechanically linking the body and the peripheral structure, the central linking structure being configured to transfer heat radially, i.e. perpendicularly to the longitudinal axis, between the body and the peripheral structure. A calorimeter cell for the measurement of nuclear heating in a nuclear reactor, comprises: at least one sample holder; a seal-tight casing in which the sample holder is placed; and temperature-measuring means.
