Rob Stewart, MIT-trained engineer specializing in steam generators and plant thermal-hydraulics, and James Krellenstein, developer focused on unlocking gigawatts from existing reactors, discuss why uprates could quickly add 6–10 GW using modern steam generators, secondary-side upgrades, and standardized side turbines. They cover why PWRs lagged, balance-of-plant bottlenecks, offsite standardized plants, and fast, repeatable delivery strategies.
