From national topical meeting on mathematical models and computational techniques for analysis of nuclear systems; Ann Arbor, Michigan, USA (8 Apr 1973). In mathematical models and computational techniques for analysis of nuclear systems. The spatial xenon control problem is considered from an operational point of view. The objective is to eliminate on-going oscillations in minimal time, with minimal control actions, under design, operational, and fuel integrity constraints, and with due consideration of operator response time and human error potential. A formal approach to practical control procedures is formulated with the aid of the Pontryagin Minimum Principle directly in terms of axial offsets, and the physical concepts underlying the procedures are clarified. Examples are given of control simulations using a digital computer on time-share mode with a remote terminal, that links the reactor core, control system and instrumentation to a human operator in continuous operation in a linear transformation of real time. Suggestions are made for the use of on-line process control computers for the implementation of the control procedures. Recent experimental verifications of the control procedures in operating large PWR plants are discussed. 9 references. (auth)
