A nuclear reactor is using 235 as fuel and is controlled by a control rod. The stable power of the reactor 1000 MW.If the control rod is withdrawn from the core such that the resulting reactivity change is 20 cents.

a. What is the instantaneous power at the prompt jump?

b. What is the power of the reactor 30 seconds after reactivity increase?

c. If the control rod is withdrawn from the core such that the resulting reactivity change is 5 cents. What is the instantaneous power at the prompt jump?

d. What is the power of the reactor 30 seconds after reactivity increase?

e. If the control rod is inserted to the core such that the resulting negative reactivity change is 10 cents. What is the instantaneous power down at the prompt jump? f. What is the power of the reactor 30 seconds after reactivity decrease?
