A core shroud is installed inside the pressure vessel in every reactor. This shroud is cylindrical in shape and is made of thick steel plate; it is not under pressure, and it does not perform a barrier function in order to contain radioactivity. ENSI assesses the integrity of core shrouds. The core shroud is open […]
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.
