Which of the following statements is true regarding nuclear power?

The statement regarding nuclear power that is true is the one that highlights its ability to offer more cargo room due to lower fuel needs. This is a significant advantage of nuclear propulsion over conventional fossil fuels. Nuclear reactors have a high energy density, which means they can produce a large amount of energy from a relatively small amount of fuel. As a result, vessels powered by nuclear energy do not need to carry as much fuel as those that rely on fossil fuels.

This reduced fuel requirement allows for more space on board, which can be utilized for cargo, equipment, or other necessary components. In many naval applications, this aspect of nuclear propulsion is particularly beneficial, enabling longer missions without the logistical burden of frequent fuel resupply.

The other statements do not accurately reflect the characteristics and advantages of nuclear power. While conventional fuels may produce more noise and contribute to air pollution, nuclear power does not share these downsides. Additionally, nuclear reactors require less frequent refueling compared to fossil fuel systems, further emphasizing their advantage in operational efficiency and extended range.
