That every reactor is too different maybe stems from idiotic regulations, ecohype and nimbyism streching build times so long that every time another one gets started there's a new design available. And not from financing, although the multidecade stretches do not help that either. EDIT: And these same delays force operation of 50 year old designs to the failure, just because building some new ones is in fact infeasible. Then those ancient reactors fail, as in Fukushima, and we're onwards on the spiral.
