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
