Some Notes on the Flexibility of Nuclear Units What is “Flexibility”? What does “flexibility” mean for a generating technology? I guess that most people would think about the ability to increase or decrease active power output (Megawatts) either on instruction, or automatically, in order to help balance generation and demand on the system. But the […]
