Containment Building

Also found in: Encyclopedia, Wikipedia.
A steel or reinforced concrete structure enclosing a nuclear reactor which is designed to, in any emergency, contain the escape of radiation to a maximum pressure in the range of 60 to 200 psi (410 to 1400 kPa), and which is the final barrier to radioactive release: the 1st being the fuel ceramic itself, the 2nd, the metal fuel cladding tubes, the 3rd, the reactor vessel and coolant system

The containment building and associated liner plate houses the reactor vessel.
The containment liner plate is a cylindrical steel shell that forms the inner wall, ceiling and floor lining of the reinforced concrete reactor containment building.
This cylindrical steel shell forms the inner wall, ceiling, and floor of the Reactor Containment Building (RCB), which is where the nuclear reactor is housed.
Chief Cabinet Minister Yukio Edano said it was possible the primary containment vessel had been damaged, with radiation leaking into the secondary containment building.
The reactor cores have two layers of containment: the reactor vessel and the containment building.
There are multiple barriers to prevent release of radiation 1 Metal cladding: Encases uranium fuel rods in reactor core 2 Reactor pressure vessel 3 Containment building 4 Control rods: Hydraulically driven into core within seven seconds 5 Emergency cooling: Diesel generators power emergency cooling.
Millions of people spent a third night without water, food or heating in near-freezing temperatures along the devastated north eastern coast; the containment building of a second nuclear reactor exploded because of hydrogen build-up while the stock market plunged over the likelihood of huge losses by Japanese industries including big names such as Toyota and Honda.
By releasing gases into the air in the containment building, the hydrogen and oxygen combined - an extremely volatile mix.
SGT's work includes heavy haul of the massive, 70-feet long, 530-ton steam generators at the plant site, creation of a temporary opening in the reactor containment building, and closure of the opening once the retired equipment is removed and the replacement components are installed.
The Chernobyl reactor was very different from the technology used in American plants, had no thick containment building to hold in radiation like plants in the rest of the world, and had poorly trained operators.
Fixatives developed in the past were designed for use only on a small scale and in controlled environments, such as inside the containment building for a nuclear-power reactor, notes physicist Christina A.
Years of analysis and preparation have led to the successful completion of this critical first phase of the project, which included erecting a large containment building over the whole tank complex.
