A PWR fueled with ²³⁵ U is initially operating at a power level of 1200 MW _t . What is the power of the reactor after 2 minutes for reactivity insertions of -15 cents and +15 cents? Assume a prompt neutron lifetime of 0.1 milliseconds. Note that in ²³⁵ U fueled thermal reactors, λ ^-1 is about 80 seconds.
