Reactor building

A reactor building is a general term for a building that houses a reactor of some type. In particular, it often refers to a building containing a nuclear reactor. This can also be used to refer to pressure sealed buildings containing nuclear reactors, though it would be more correct to call them containment buildings.

Although some buildings containing nuclear reactors are containment buildings, not all are. For instance, the Soviet RBMK reactors were not housed in containment buildings. This greatly increased the severity of the Chernobyl accident on April 26, 1986.
