AMHYCO

The AMHYCO project proposes innovative enhancements on the way combustible gases are managed in case of a severe accident in European Gen II/III reactors in operation.

To achieve this goal, the AMHYCO project has three main specific objectives:

• Objective 1: To improve the Severe Accident Management Guidelines (SAMGs) for both in-vessel and ex-vessel phases with respect to combustible gases risk management, using both numerical and experimental results.

• Objective 2: To investigate experimentally phenomena that are difficult to predict numerically: H2/CO/H2O combustion and PARs behavior under realistic accidental conditions, considering the safety systems interaction.
• Objective 3: To improve the predictability of the numerical tools – Lumped Parameter (LP), 3D containment and Computational Fluid Dynamic (CFD) codes – used for explosion hazard evaluation inside the reactor containment to gain relevance in supporting SAMGs design and development.
