Review of CALORRE Calorimeter Characterizations Under Laboratory and Irradiation Conditions

This article reviews the work to date on CALOrimeter with Radial thermal transfers for nuclear REactors (CALORRE) differential calorimeter patented by Aix-Marseille University (AMU) and French Alternative Energies Atomic Energy Commission (CEA) in 2015. The presents results obtained first prototype of CALORRE qualified under real conditions during an irradiation campaign MARIA reactor 2015, including previously unpublished details. Then, studies different calorimetric cells characterized experiments laboratory are described. Several configurations were studied determine influence cell height, horizontal fin geometry, structural material composition response. These calculations provide a calibration protocol generating heat source inside each cell, evaluation linearity, sensitivity, range, reproducibility, response time, absolute temperatures. Finally, within framework new research program called Compact-CALORimeter Irradiations MIT (CALOR-I) financed AMU Foundation (A*Midex), design optimization assembly was carried out order remove contact resistances very compact suited in-core water loop Massachusetts Institute Technology (MIT) (2 $\text{W}\cdot \text{g}^{-1}$ peak heating rate). this is estimated using 3-D numerical simulations conditions.
