The numerical works presented in this paper belong to the IN-CORE (Instrumentation for Nuclear radiations and Calorimetry Online in REactor) research program. Its scientific aim is to create a new device dedicated to the online simultaneously measurements of nuclear conditions inside experimental channels of the Jules Horowitz Reactor (JHR) by coupling different sensors. This paper studies a specific one: a radiometric calorimeter used to in pile nuclear heating measurements. Numerical simulations on heat transfers taking place into this sensor under radioactive and nonradioactive conditions are carried out. The influence of the geometrical dimensions and of the energy deposit on the heat flux density, on the sensor sensitivity and on the maximum temperature is discussed.
