First, the study was just released yesterday. You may have also seen a letter by Dr. Reyes, who was the inventor, and also faculty at the University of Oregon, who predominantly stated that the assumptions used in that study for the NuScale small modular reactor were in fact incorrect. In his letter, he outlined that it is not accurate and therefore should be disregarded.
With that already issued by the inventor of the NuScale technology, I think that report needs to be examined in detail before any conclusions would be drawn from it or actions taken from it.
