TEST III THERMO I 4/25/04 1) (33%)  An engineering firm wants to design a nuclear power plant to  provide heat transfer to a Carnot engine to provide power to electrical  generators.  The outlet temperature from the reactor (inlet to the Carnot  engine) is 527°C, and heat transfer from the Carnot engine to the plant  cooling water takes place at 27°C. The design power output of the Carnot  engine is 1100 MW. a)  How much power (MW) must be generated by the nuclear reactor to  provide the required output from the Carnot engine?
