Special Concrete Required for Small Modular Reactors (SMR's), page-2

"In the construction of SMR's, lots of concrete is required. This concrete must have radiation-shielding properties, irradiation resistance, durability, energy-absorption capability and high-temperature resistance. In addition, its mechanical properties are also hugely important i.e. it must be High-Performance/High-Strength Concrete-HPC/HSC. Therefore, IMVHO, EdenCrete is highly likely to be very suitable."


Absolute rubbish. The reactor itself handles all the radiation, temperature and energy absorbing. The concrete is just a slab to keep the reactor level. In this case 20yd3 would be ample.

In any case adding CNT doesn't turn ordinary concrete into HPC. It just turns cheap low quality concrete into very expensive mediocre concrete,
