A nuclear power plant has a maximum steam temperature (TH) of 280 degrees C. It produces 790 MWof electric power in the winter, when its is effectively -7 degrees C .
Find the maximum winter efficiency.
Then, if it is summertime TC is 40 degrees C, what is the summertime electric power output assuming nothing else changes?
