7. A Rankine cycle is used at nuclear power plant with water as the working fluid. The steam is expanded in a high pressure turbine, producing 700 kW of power. The steam is then reheated in the nuclear reactor, and expanded in a low pressure turbine, producing an additional 300 kW of power. The water pump for the facility consumes 50 kW. if 3,100 kW of energy is rejected in the cooling tower, what is the thermal efficiency of the power plant?

A) 47% B) 35% C) 25% D) 23% E) None of the Above
