Abstract Two types of monitoring systems suitable for automatic nuclear reactor control are discussed. In the first system, the detector monitors some given point, such as a preset constant neutron flux. This system is suitable for combining the functions of the period meter and indicator, the power level and critieality of the reactor indicators, and for reactor safety control. In the second system, the reactor power follows detector displacement. Such a system can combine the automatic control functions for critieality, period, and power level of the reactor. If a scheme incorporating monitoring systems of both types is devised, then two variations of complex automation of reactor control may be developed. The first variation is easier to adapt to existing installations. The second variation is more sophisticated, and is suitable, probably, for new installations. The advantages of the proposed schemes are that they consist of simple standard elements, that they make possible servo control, and that they ensure constant operating conditions for the detector and apparatus.
