Question

At a nuclear power plant, a steam turbine drives an electrical generator with a mechanical power output of 330 MW. The power input from the nuclear reactor to the steam turbine is 1300 MW. How much power is discarded by the turbine?

A 1300 MW
B 970 MW
C 330 MW
D 1630 MW

Answer 1

The discarded power by the turbine at a nuclear power plant, is calculated by subtracting the mechanical power output (330 MW) from the power input (1300 MW), which equals 970 MW. The correct answer is B: 970 MW.

Step-by-step explanation:

The power discarded by the turbine at a nuclear power plant is the difference between the power input from the nuclear reactor and the mechanical power output that drives the electrical generator. In this case, the power input from the nuclear reactor is 1300 MW and the mechanical power output is 330 MW. The power discarded, therefore, is 1300 MW - 330 MW, which is 970 MW.

The correct answer is B: 970 MW.
