The closure head of the reactor pressure vessel has been lifted inside the reactor building

1.10.2010

The introduction of the main reactor island components was continued on Thursday 30.9. This time the 90 tons closure head of reactor pressure vessel was lifted inside the reactor building.

The closure head is waiting on a storage rack for its final placement on top of the pressure vessel. The rack is the same where it is lifted during outages.

Just like the pressure vessel, the closure head is made of forged ferrite steel and clad with stainless steel on the inside to prevent corrosion.
