Question

what is the direct function of the energy released from the nuclear chain reaction in a nuclear power plant?
○ turning the blades of the turbine
○ heating water to produce steam
○ powering the condenser
○ carrying electricity from the plant to consumers

Explanation:

In a nuclear power plant, the energy from the nuclear chain reaction (fission) is first used to heat water. This heated water produces steam. The steam then turns the turbine blades (so turning the turbine is a subsequent step, not direct). Powering the condenser is not the direct function of the nuclear reaction's energy, and carrying electricity to consumers is the final step of power distribution, not the direct function of the reaction's energy. So the direct function of the energy from the nuclear chain reaction is heating water to produce steam.

Answer:

B. heating water to produce steam
