What is the future of small modular reactors?

 My first thought on reading of Tufan Erginbilgic taking up his new post as chief executive of Rolls-Royce was that the SMR programme was in doubt, because of his history with BP and his statement that R-R's
current investment strategies are 'unsustainable'. However, he also comes from Global Infrastructure Partners, which is making the right noises about climate change, though purists may quibble about the organisation's advocacy of natural gas as a transition fuel from coal.
