All About Construction

Many might be wondering how does Nuclear Plant reactors (Domes) are constructed.  Reactor Building The 88 meters tall structure of the main Reactor building has been done with a novel raft design for the reactor structure. The reactor building raft has a foundation at 8.85 meters below the ground level. The thickness of the raft foundation is 4.6 meters at the end and 1.6 meters in the middle. The containment base slab is at 1.1 meters above ground level and 5.35 meters above the foundation which is of 1800mm thick and the total concrete quantity of this slab is 6000 Cum. The containment base slab supports the core of the nuclear reactor placed in the reactor cavity at the center of the containment structure. Inner Containment Structure · Inner containment wall starts from +5.35 M above ground level and goes up to +43.9 meters as cylindrical part with a dia of 44 meters. · The hemispherical dome starts from +43.9 meters with radius of 22 met...

When an earthquake and tsunami struck the Fukushima Daiichi nuclear plant complex in 2011, neither the quake nor the inundation caused the ensuing contamination. Rather, it was the aftereffects -- specifically, the lack of cooling for the reactor cores, due to a shutdown of all power at the station -- that caused most of the harm. A new design for nuclear plants built on floating platforms , modeled after those used for offshore oil drilling, could help avoid such consequences in the future. Such floating plants would be designed to be automatically cooled by the surrounding seawater in a worst-case scenario, which would indefinitely prevent any melting of fuel rods, or escape of radioactive material. The concept is being presented this week at the Small Modular Reactors Symposium, hosted by the American Society of Mechanical Engineers, by MIT professors along with others from MIT, the University of Wisconsin, and Chicago Bridge and Iron, a major nuclear plant and offshore ...
