PWR plants are pretty flexible at the starting of their cycle, with fresh fuel and higher reserve reactivity. An EdF reactor can minimize its energy from one hundred% to 30% in 30 minutes. But when the fuel cycle is about 65% through these reactors are significantly less versatile, and they take a swiftly diminishing part in the third, load-following, aspect above. When they are 90% through more bonuses the fuel cycle, they only take element in frequency regulation, and essentially no energy variation is allowed . So at the really end of the cycle, they are run at steady energy...
