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.
Primary containment requires using proper storage containers, good microbiological technique, and the use of appropriate safety equipment such as biological safety cabinets. Secondary containment is the protection of the environment external to the laboratory from exposure to infectious materials and is provided by a combination of facility ...
This system consists of a series of pumps and spargers that spray coolant into the upper portion of the primary containment structure. It is designed to condense the steam into liquid within the primary containment structure in order to prevent overpressure and overtemperature, which could lead to leakage, followed by involuntary depressurization.
While biocontainment, as defined in the Biosafety in Microbiological and Biomedical Laboratories [18] and Primary Containment for Biohazards: Selection, Installation and Use of Biosafety Cabinets [18] manuals available at the Centers for Disease Control and Prevention website much of the design, implementation and monitoring of protocols are ...
Containment was a geopolitical strategic foreign policy pursued by the United States during the Cold War to prevent the spread of communism after the end of World War II. The name was loosely related to the term cordon sanitaire , which was containment of the Soviet Union in the interwar period .
A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level.

The GE Mark III Containment-system is a single barrier pressure containment and multi-barrier fission containment system, consisting of the containment vessel plus associated dry- and wetwell (pressure and fission barriers), the external shield building of it, the auxiliary building and the fuel building, all of which are normally kept at ...
