A containment dome is a component of the system designed to contain the underwater blowout of an oil well such as occurred with the Macondo Well blowout from the Deepwater Horizon oil spill. [1] This portion of the system is designed as a vacuum to suck up the products being expelled from a blowout and deliver those products to the containment ...
The engineering function of a GCL is containment as a hydraulic barrier to water, leachate or other liquids and sometimes gases. As such, they are used as replacements for either compacted clay liners or geomembranes, or they are used in a composite manner to augment the more traditional liner materials.
Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs. Suppression systems are critical to safety analysis and greatly affect the size of containment.
Most nuclear power plants feature a containment building whose role is to be the ultimate barrier, as per the defense-in-depth principle, against the release of radionuclides in the environment during accidents involving partial or total reactor core damage, that is, in which the integrity of the nuclear fuel (first barrier) is lost.
An example of a safety system with passive safety components is the containment vessel of a nuclear reactor. The concrete walls and the steel liner of the vessel exhibit passive safety, but require active systems (valves, feedback loops, external instrumentation, control circuits, etc.) which require external power and human operation to function.
Secondary functions of these devices may include explosion protection, spill containment, and other functions necessary to the work being done within the device; these functions may be achieved through enclosure design, duct design, and optimal placement of the fume hood in a room.

A double-walled pipe is a secondary contained piping system. It is a pipe within a pipe, or encased in an outer covering, with an annulus (interstitial space) between the two diameters. The inner pipe is the primary or carrier pipe and the outer pipe is called the secondary or containment pipe.
