Description of the thesis topic
This thesis project concerns the development of instrumentation to detect and monitor the progression of a nuclear accident, in order to implement the most appropriate accident management as soon as possible. Different types of sensors can be considered to detect fission products in the containment of a nuclear reactor during a severe accident.
Today, several technologies exist for the detection of radioactive gases (in particular those based on iodine) that may be emitted during a nuclear accident. However, these technologies show limitations that make their use impossible in a severe accident situation. In order to solve this problem, we propose in this project to develop specific sensors using porous materials of the Metal-Organic Framework (MOF) type for the selective detection of radioactive agents and in particular molecular iodine I2. Indeed, MOFs have both a very high porosity allowing to concentrate tiny quantities of species (ppb), but also an adaptable framework for the immobilization of iodine within the material. Thus, this thesis work will focus on the manufacture of nanometric MOFs, specific to molecular iodine, and which can be adapted to already existing detector technologies. This research work will be mainly carried out on the Villeneuve d'Ascq campus. A first part will involve two research teams, one for the manufacture of nanometric MOFs for the capture of radioactive agents (UCCS, C. VOLKRINGER) and the other for the manufacture of specific sensors (IEMN, Y. COFFINIER).
Candidate profile.
We are looking for a chemist or physical chemist with a bac+5 level, with knowledge of the synthesis and characterization of materials. Signal processing skills are appreciated, but not mandatory.
Work Context
This research will be carried out mainly on the Villeneuve d'Ascq campus. The first part will involve two research teams, one for the production of nanometric MOFs for radioactive trapping (UCCS, C. VOLKRINGER) and the other for the production of specific sensors (IEMN, Y. COFFINIER).
The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
Constraints and risks
The resistance to accident conditions of the developed sensor will be studied in close collaboration with the Nuclear Safety and Radioprotection Authority on the Cadarache and Saclay sites.
