General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Thèse
Job description
The objective of the thesis is to develop a methodology for stability analysis and control, tailored to the unique characteristics of the energy conversion cycle of a Small Modular Reactor operating in cogeneration with grid service. The doctoral student will first focus on the control of the steam generator (SG) for a given technology, first with the development of a 1D dynamic model of the SG and then its flow stability analysis. Investigation of the control-command strategies will be progressively extended by coupling the GV to the energy conversion system and primary loop: the appropriate conditions for frequency control or load follow operation will be sought, in both electrical and cogeneration production modes. The approach should make it possible to quantify the gain that could be expected from advanced control techniques using machine learning in particular. Different mdeling tools will be used, including Dymola, Matlab together with some internal CEA or free tools.
The thesis benefits from a dual academic supervision. It will take place in the Innovative Nuclear System Study R&D Unit of the Nuclear Systems Research Institute at CEA Cadarache. The doctoral student will develop skills in energy conversion, thermohydraulics, control (strong component of the thesis) and artificial intelligence.
