Nuclear safety: chemical kinetics, combustion, reactivity

Head : Florent LOUIS
Co-head : Frédéric COUSIN

The research team results from collaborative research activities initiated in 2006 between the PC2A laboratory and the "Pôle de Sûreté Nucléaire" from the "Institut de Radioprotection et de Sûreté Nucléaire" IRSN on topics relative to the thermodynamics and chemical reactivity of specific compounds. The complimentary and the skills of both partners allowed to make long-lasting this collaboration by creating in 2009 the common research laboratory IRSN/CNRS/Lille1 C3R "Chemical Kinetics, Combustion, and Reactivity". The research activities concern problems covering a wide spectrum of the homogeneous and heterogeneous reactivity using different approaches (experimental, molecular simulations, modelling). The main objectives of the led researches are to validate the estimations of radio-contaminant releases if a severe nuclear power plant accident type Chernobyl and the more recent Fukushima disaster was to occur.

Several research activities are now under study :

Topic 1 : Iodine chemistry from the power plant to the atmosphere
Topic 2 : Interaction of gaseous iodine with sodium aerosols
Topic 3 : Revolatilisation of fission products deposits
Topic 4 : Gaseous iodine compounds metrology

Last publications of our team:

1) Reactivity of Hydrogen Peroxide with Br and I Atoms

2) MS-CASPT2 study of the ground and low lying states of CsH+

3) Investigation of the Reaction Mechanism and Kinetics of Iodic Acid with OH Radical Using Quantum Chemistry

4) Caesium hydride: MS-CASPT2 potential energy curves and A1Σ+→X1Σ+ absorption/emission spectroscopy
