In a thermal reactor the mean lifetime of one generation
of thermal neutrons is ti = 0.10 s. Assuming the multiplication
constant to be equal to k = 1.010, find:
(a) how many times the number of neutrons in the reactor, and
consequently its power, will increase over t = 1.0 min;
(b) the period T of the reactor, i.e. the time period over which
its power increases e-fold.
