Question

a nuclear power technician determines that the fission rates need to be increased. which of these tasks will the technician most likely carry out?
increasing the amount of fissionable material in the reactor
shutting off the condenser
increasing the speed of the turbine
raising control rods from the reactor
done

Explanation:

• To increase fission rates in a nuclear reactor, control rods (which absorb neutrons and slow fission) are raised to allow more neutron interactions.
• Increasing fissionable material isn’t typical (reactor has fixed fuel), shutting off the condenser affects steam/turbine, not fission, and increasing turbine speed is a result, not a cause of increased fission.

Answer:

D. raising control rods from the reactor
