when a heat wave strikes a region causing more people to run air - conditioning units, electrical demand increases. what needs to be done to meet this increased demand?\nlowering the control rods\nraising the control rods\nremoving the control rods
Answer
Explanation:
Step1: Understand control rod function
Control rods in a nuclear reactor absorb neutrons.
Step2: Analyze effect on power output
Lowering control rods absorbs more neutrons, reducing reaction rate and power output. Raising or removing them increases the reaction rate and power output.
Step3: Match with demand
To meet increased electrical demand, power output should increase. So, raising or removing control rods is needed. Among the options, raising the control rods is correct as removing them completely is not a typical normal - operation action.
Answer:
raising the control rods
