The core shroud separates the flow directions of reactor cooling water and water at different temperatures.

It is not under pressure, and it does not perform a barrier function in order to contain radioactivity. The core shroud is open at the bottom and the top.

The hydrodynamic conditions in pressurised water reactors differ from those in boiling water reactors. For this reason, the core shroud in pressurised water reactors performs a slightly different function. The core shroud we are talking about here is installed in boiling water reactors such as those at Mühleberg and Leibstadt.
