Investigation of alternative solutions for PWR severe accident management: Objectives of the CEA 'Innovations - Future reactors' Program

摘要

The "Innovations - Future reactors" program is the result of the Nuclear Reactors Directorate and the Advanced Technologies Directorate pooling their R&D capabilities and competence. This was done in order to envisage, evaluate and if necessary, validate all technical options which can be of interest for future reactors. The objectives of these studies are: to improve the economic competitivity of nuclear energy, to increase reactor safety and to optimize the fuel cycle and the management of nuclear materials. For these purposes, the program has five main axes : Firstly, the core and fuel cycle studies aim at improving the flexibility of reactor operation and increasing fissile material burn-up while at the same time reducing the accident risks linked to the physics of the process;
