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.

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