The high costs of building new powerplants is a result of going decades without building any, leading to a loss of experience. Even still, nuclear remains competitive with other traditional power generation technologies like coal. Only with recent advancements in fracking did natural gas supplant coal as the go to fuel, and Wind and solar have become extremely inexpensive, but only in the past 10 years, in large part due to a concerted effort to scale up those industries. In other parts of the world where nuclear power did not have a decades long hiatus it remains extremely competitive with even these renewables, for example in South Korea where LCOE for nuclear is half that of solar.&lt;p&gt;Of course you may have only became bearish on nuclear when the costs got high, but there are a large number of people who were bearish before then, which is what made costs high.&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.sciencedirect.com&amp;#x2F;science&amp;#x2F;article&amp;#x2F;pii&amp;#x2F;S0301421516300106&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.sciencedirect.com&amp;#x2F;science&amp;#x2F;article&amp;#x2F;pii&amp;#x2F;S030142151...&lt;/a&gt;</text><parent_chain><item><author>tomComb</author><text>Yes, cost is the issue.&lt;p&gt;Everyone assumes that anyone hesitant about Nuclear power is focussed on the environmental or safety concerns, but that is wrong.
