You are talking about an amount of money that exceeds the easily available resources of the developer. That is true of nuclear but it is also completely normal in renewables. Projects if all types need financing. That could be a $200k anaerobic digester on a farm or a $7b offshore wind farm. But at every level the investor or bank will need to do due diligence and understand the risk. Different types of project require different levels of expertise to do that. A battery storage site is relatively simple and within the scope of smaller investors. An offshore wind farm might need large banks and energy companies. A nuclear power plant is in a completely different league in terms of expertise required. A bank will find it difficult to even understand the risk.
