8d ago It's not even that complicated. 2/3 of the costs of a nuclear power plant is *interest cost on concrete/construction*. They payback comes over the course of 40-80 years. -1.5
8d ago Yeah, and a lot of the historic cost of running the nuclear fleet in the UK was down to appalling/amateur management by the electricity board priory to privatisation. -2.5
8d ago Where is China’s cost saving coming from? Also, surely it becomes irrelevant if solar continues the exponential cost decrease it has followed over the last 5 decades? (Your plot of nuclear is lin… +2.0
