Nuclear power plants convert the energy released in fission reactions to electric energy. Consider one such power plant that generates 1.00 GW of electric power. The fission of each uranium-235 nucleus releases 250 MeV of energy. The power released by the fission reactions is converted to electric power with a 41.0% efficiency. How much uranium-235 per day, by mass in kg, undergoes fission at this power plant?
The energy released by each fission within the core of a nuclear reactor is 2.00 x 102 MeV. The number of fissions occurring each
second is 2.90 x 1010, Determine the power (in watts) that the reactor generates.

Suppose enriched uranium containing 3.70% of the fissionable isotope 23592U is used as fuel for a ship. The water exerts an average friction force of magnitude 2.50 105 N on the ship. How far can the ship travel per kilogram of fuel? Assume that the energy released per fission event is 208 MeV and the ship's engine has an efficiency of 20.0%.
