The document examines whether a nuclear renaissance is fact or fiction by analyzing potential drivers and constraints. It finds that while nuclear power provides clean energy and energy security, industrial bottlenecks, high costs, and politics make a large-scale renaissance unlikely. Climate change and energy security concerns may slightly favor nuclear power, but are not strong enough drivers to overcome constraints like industrial limitations and expensive upfront costs compared to alternatives. On balance, the analysis concludes a nuclear renaissance is improbable.
