Hydrogen degassing measurement station on 870 L packages (in black) at the CEDRA storage facility, CEA Cadarache. The containment enclosures (grey), adapted to the type of package, allow the accumulation of gases released from the package. A sample of the atmosphere of the chamber is then measured by gas chromatography (bottom left). The chromatogram (bottom right) shows the separation of the different gases in the atmosphere (hydrogen corresponds to the second peak).
