A reactor has a eff of 0.421sec -1 and an effective delayed neutron fraction of 0.00602.

A reactor has a λ_eff of 0.421sec^-1 and an effective delayed neutron fraction of 0.00602. If k_eff is equal to 1.002, what are the stable reactor period and the SUR?

Question 2

A reactor critical at 200 watts has 175 pcm of negative reactivity is added. λ_eff for the reactor is 0.059 sec^-1 and the effective delayed neutron fraction is 0.0075.

1. Calculate the steady state period and startup rate.
2. Calculate the power level 14 minutes after the reactivity insertion.

Question 3

A reactor has a power level of 400 watts and a doubling time of 4.75 minutes. What is the reactor power level 7 minutes later?
