Steel plate—reinforced concrete containment vessel

Steel plate-reinforced concrete containment vessel... 

The construction period will be shortened by the use of a steel containment vessel, a steel plate-reinforced concrete (SC) structure in building structures and by the implementation of a large block construction and modular construction approaches, in addition to the lower stories of the R/B.

Conventional concrete structures, and prefabricated steel structures assembled on site and filled with concrete after placement are used in various structures. Precast concrete modules would also be used. Wide use of removable formwork is employed to limit steel exposure to potential corrosion. Prefabrication of reinforced rebar modules is extensively used. In some places mechanical rebar splices are used to reduce the weight of prefabricated modules. All of these techniques have been employed in previous nuclear power plant construction. Steel structures such as the air baffle, and the containment vessel are constructed of steel panels. Panels are made of stiffened steel or corrugated plate depending on availability and cost panels for the baffle are designed with thermal expansion of the containment vessel in mind. Future inspection and maintenance are taken into consideration.
