The efficiency of a nuclear power plant in comparison to a conventional thermal power plant is

A Same
B More
C Less
D May be less or mote depending on size

Correct Answer: Less

The efficiency of a nuclear power plant in comparison to a conventional thermal power plant is less.
Typical nuclear power plants achieve efficiencies around 33 - 37%, comparable to fossil fueled power plants. Higher temperature nuclear reactors could potentially reach above 45% efficiency.
