Steel Containment


The containment is used for safe enclosure of all of the nuclear components of a nuclear power plant. In most cases it is a spherical shell of high-strength steel, which is provided with numerous gas-tight openings and penetrations.

During power plant operation, a slight vacuum prevails in the containment which prevents radioactive substances from escaping into the surrounding area in the event of a leak. To cope with accidents it is dimensioned for specified overpressure loads.

The relevant competence for design and construction is still available within Babcock Noell Nuclear.

Typical technical characteristics:

Sphere diameter : 56 m
Design pressure: 5,3 bar
Weight: approx: approx.. 2600 to
