What is the difference between BWR and PWR in the case of SEFs?
There are two very basic differences one in terms of coolability design and the second in terms of margin to fuel limits.What is the difference between BWR and PWR in the case of SEFs?
There is some amount of nucleate boiling during operation of a PWR, and it's not necessarily bad. It is the departure from nucleate boiling that leads to increased fuel and clad temperatures in a PWR, just as in a BWR....
In terms of core margin. A PWR operates at higher pressures and temperatures and is noit designed for any boiling (ONB or onset of nucleate boiling is bad for a PWR...
You got that right, NUCENG.... That is not a simple question with a two paragraph answer.
