This CF question is actually quite complex. You can have a CF of 0.7 for
a nuke but actually that's because it's working 70% of the time and for
30% it is broken or undergoing maintenance (often for longish periods of
days / weeks / months). A CCGT with a CF of 0.7 would most likely be
Oliver
Actual output for nuclear is typically around 0.7 but the carbon debt
was all incurred before operation and turning them off does not reduce
it. The carbon for the plant is all released before operation and if
this is delayed we may ask if there is a carbon equivalent of interest.
