alt Hacker NewsI agree, the experience building nuclear reactors is mixed bag. Some builds failed, like Flamanville 3, Hinkley Point C, Vogtle 3. Some builds succeeded: Barakah nuclear power plant, Fuqing 5,6. It really depends on maturity of supply line and political support.
The real question is: how do we produce hydrogen from the coming massive overbuilding of cheap-but-variable solar. Nuclear reactors are a whole different animal: even if we build them "cheaply" they're not going to approach the costs of overbuilt solar, so those nuclear watts will be better used for other purposes.
