The vacuum container is a constituent part of the CNS vacuum assembly.
It is a sealed vacuum vessel which houses the CNS. The vacuum container is designed to localize consequences of potential accidents at the Cold Neutron Source, including the detonation of a stoichiometric deuterium-air mixture at atmospheric pressure (1.01´105 Pa).
Its body has six adjustable supports and is secured to the wall-mounted brackets by the tie-rods.
The handling platform has guard rails and balconies to get access to the vacuum container parts to be maintained.
The vacuum container body is five-sectional. The sections are joined by flanges with sealing gaskets. The vacuum container has a special retainer to protect and align the CNS inside its body.
