This paper addresses the problem of suppressing the magnitude of hot spots in plug flow reactors by manipulating the jacket coolant temperature. A nonlinear control law is derived which guarantees that the hot spot temperature remains below a pre-specified bound for all times after an initial transient, under relatively mild assumptions on the inlet conditions. The performance and robustness of the derived control law are evaluated for the case of a first-order irreversible exothermic reaction.,
