50% capacity factor for nuclear power is an aberration: typical capacity factors are over 90% [1] [2]. By comparison, capacity factors between 20-35% for wind and solar are the norm. Nuclear's capacity factor problems are also solve-able: France identified that irregular metallurgy caused faster corrosion, and this informs future builds. Nothing can make the wind blow more consistently, or make the sun stay in the sky for longer.
