US Congress passes bill to help advanced nuclear power
Policy will is one obstacle, but high costs are the main factor. Compared to new gas plants, new nuclear plants are extremely expensive. Look at the debacle in South Carolina and you can clearly see: new nuclear is not working (outside China). Old nuclear is still a huge portion of the carbon-free electric grid in parts of the USA and Europe, especially in other countries like France. I do believe that if carbon were taxed based on its negative effects, nuclear would get the much-needed economic re-conception that allows it to proliferate. It can and should be a climate solution, alongside batteries and renewables.
