Nobody is saying nuclear is cheap it is not - we will be building a plant once in while for pure strategic reason no matter the cost anyway. The point is construction cost comes down per MW with higher frequency of plant building, and this is the case SMRs, we can get cheaper construction both Per MW and overall TCO in absolute dollar terms relative to large plants with SMRs.
