> This reactor indeed has lower power density than a PWR, but not by a factor of 12. It's more. > while NuScale has a volume of 101 m3 and yields 77 MWe VVER1200 has the inner vessel _diameter_ of 4.2m, height of 11m for the internal volume of 153m^3, and 1200MWe capacity (so around 3GWt). _THIS_ is what you're comparing it with. > Quite the opposite happens: fuel elements in the current generation PWRs tend to swell, crack and burst Nope. A swollen or a ruptured fuel rod in a regular reactor is a reason for SCRAM. The water inside the reactor vessel is constantly monitored for fission products. The individual fuel tablets swell, but they are contained inside zirconium rods.
