Anuclear 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

Option (4)

Explanation:

Control rods are defined as those device that are commonly used in order to absorb neutrons. This helps in either increasing or decreasing or stopping the nuclear chain reaction that takes place inside a reactor core. This increases the fission rate by slightly removing the control rods. On the other hand, the fission rate can be decrease or stop by pushing the rod further inside.

This is how the rate of fission can be increased by raising the control rods from the reactor.

Thus, the correct answer is option (4).
