ABSTRACT
THE APPLICATION OF DIGITAL TECHNIQUE IN THE RESEARCH REACTOR CONTROL SYSTEM. Research reactor is a multifunction nuclear reactor that provide neutron sources and gamma radiation for use in some activities. This wide range of activities necessitates frequent adjustments of a research reactor power. To increase the flexibility of operation with high degree of safety, the research reactor control system should be automated. The automation can only be done when the control system is change from analog to digital. This paper describes the model-based control systems for used in research reactor that was designed by period-generated control method. This control system is designed by combining feedback and feed forward control techniques that can be control non-linear system. The rate of change of reactivity is used as actuator signal. Performance test has been conducted in MITR-II owned by Massachusetts Institute of Technology and ACRR that is operated by Sandia National Laboratories. The result shows that the model-based digital control system is superior to control the research reactor operation.
