> I don't follow what you're saying about 'GEN IV' reactors. AFAIK, that's reactors of a type that won't be online until at least 2030 As I mention, Superphénix is a Gen IV, and was finished building in 1981. > the primary failure at Fukushima was a sea wall too low for the tsunami that occurred. How is the reactor design relevant? Fukushima melt down because the water destroyed the backup generators. The generators are used to power the pumps. The pumps force coolants to flow, removing heat and therefore avoiding an increase in temperature beyond what is structurally sound. A typical Gen IV reactor would naturally cool down without need to keep coolant running. For instance, Superphénix immerses the breeder in a liquid sodium coolant that has an effectively unreachable boiling point, tremendous heat capacity, and no corrosion.

Superphénix: During 11 years, the plant had 53 months of normal operations (mostly at low power), 25 months of outages due to fixing technical problems of the prototype, and 66 months spent on halt due to political and administrative issues. It was then closed early.

>As I mention, Superphénix is a Gen IV, and was finished building in 1981. No, it isn't and wasn't. The Gen IV FBR types are only GFR, SFR, LMFBR and SCWR. From the link I provided earlier 'In January 2018, it was reported that "the first installation of the pressure vessel cover of the world's first Gen IV reactor" had been completed on the HTR-PM.'

Its first version, Phénix, is literally cited in the official Gen IV description of what an SFR is[0]. Historically, it has not been labeled Gen IV, but only because the Gen IV nomenclature didn’t exist at the time.
