During a severe accident, combustible gases can be released, leading to a potential explosion risk in the nuclear containment building. These gases — including hydrogen and carbon monoxide — need to be managed to avoid threatening the containment integrity, which can result in the release of radioactive material into the environment.
The AMHYCO idea came from discussions held in another project: SAMHYCONET when some partners identified that there were some areas of safety that could be further investigated. The AMHYCO research teams will conduct experiments and simulations in order to best replicate realistic conditions of severe accidents (SAs) in order to respond to practical questions, such as the right timing and mode for actuation of containment safety systems (i.e., FCVS, sprays, fan coolers) regarding combustion risk management. Cutting-edge tools (i.e., LP, 3D and CFD codes), experimentation and the best use of engineering judgement will be combined to produce recommendations that accurately reflect those realistic SA scenarios.
The AMHYCO project idea and program have been supported by the NUGENIA Executive Committee, receiving the NUGENIA label, awarded to projects that show a high level of quality in their research proposal.
