A coal-fired electrical generating station can use a higher TH than a nuclear plant; for safety reasons the core of a nuclear reactor is not allowed to get as hot as coal. Suppose that TH = 727°C for a coal station but TH = 527°C for a nuclear station. Both power plants exhaust waste heat into a lake at TC = 27°C. How much waste heat does each plant exhaust into the lake to produce 1.00 MJ of electricity? Assume both operate as reversible engines.
