A very important type of radioactive decay process in nuclear reactors is one in which fission products decay by neutron emission since such processes strongly influence the time behavior of the fission chain reaction. The slowest such decay process in most reactors is one characterized by a decay constant of 0.0126 sec-1. Assuming that such a process controls the rate at which one can decrease the power level of a reactor, calculate the tin*e necessary to decrease the reactor power level from 3800 MW (thermal) to 10 MW (thermal).
