A treatment of the problem of optimum control of the process of shutting down a high-flux thermal-nuclear reactor to minimize the effects of xenon-135 poisoning. The problem is handled by the functional-equation technique of dynamic programming, relying on the use of high-speed digital computers with large memories. Classical methods of the calculus of variations do not seem applicable to the resulting extremal problem.
