“…This latter quantity is measured on-line by means of specific sensors: non-adiabatic calorimeters. These sensors must be preliminary studied under laboratory conditions by out-of-pile characterization and calibration and then require qualification and/or validation under real conditions thanks to several irradiation campaigns [4][5][6][7].…”

“…The CALORRE calorimeter was patented by AMU and the CEA in 2015 [8,9]. A first prototype was tested successfully for the first time in November 2015 in the MARIA reactor [6,7]. The third objective of this program is to map a dedicated in-core water loop of the MIT Research Reactor (MITR) in terms of nuclear heating rate using the new reduced-size prototype of CALORRE developed and optimized thanks to coupled thermal and neutronic modeling.…”

This paper presents the preliminary characterization of a new reduced-height CALORRE differential calorimeter designed and fabricated for the irradiation in the MITR within the framework of the CALOR-I program. The paper begins by focusing on the preparation of the irradiation campaign, providing a brief and concise description of the MITR core and the newly fabricated differential calorimeter assembly. Next, the paper presents the preliminary experimental characterization conducted under laboratory conditions. This section includes a detailed presentation of the updated experimental set-up and the key metrological characteristics of the sensor response obtained from the first experimental results. Furthermore, the paper estimates and highlights the responses of the calorimeter calculated by means of a 3-D numerical thermal model under real conditions considering local heat sources determined by the NRL of the MIT using MCNP code. In conclusion, the paper offers some final remarks and prospects to realize the irradiation campaign successfully.

“…In 2015, a new differential calorimeter (named CALORRE) comprising two compact calorimetric cells using predominantly radial heat transfer was patented by AMU and CEA [10] and successfully qualified in the Polish MARIA research reactor [11]. Recently, this calorimeter has been improved as part of the CALOR-I project to achieve a smaller size of 89.5 mm axial height (instead of 222.5 mm previously) and an innovative design to eliminate contact thermal resistances [12]. This new prototype will shortly be qualified in the MIT reactor in-core water loop.…”

This paper presents the study of a new innovative heat flow single-cell calorimeter dedicated to the measurement of the nuclear heating rate in research reactors. Before irradiating this type of sensor, it is necessary to characterize it under laboratory conditions to determine its metrological properties. A general description (design, geometry and materials nature) of this new calorimeter will be given, focusing on the motivations that led to its development. This part will be followed by a presentation of the experimental set-up and operating protocol used to characterize this sensor. The sensor sensitivity and response time will be quantified and discussed with a comparison of those obtained with previous calorimeters. In parallel with these experimental characterizations, parametric 3-D numerical simulations will be carried out using COMSOL Multiphysics software. These results, obtained both experimentally and numerically, will be compared to present a complete calorimeter study under laboratory conditions.
