Question 43

During a routine maintenance procedure at a nuclear power station, operators need to safely reduce the thermal power output of a pressurized water reactor (PWR) to a fraction of its maximum capacity.

Explain how the physical positioning of the control rods within the reactor core is adjusted to achieve this reduction in power, and describe the microscopic mechanism involved.
