Development and Testing of the Control Algorithm of the Korean Multipurpose Research Reactor

Abstract

This paper describes the development and implementation of the Reactor Regulating System (RRS) control algorithm for the Korean Multipurpose Research Reactor (KMRR) on an industrial digital control computer. The general overview and description of the KMRR reactor together with the control requirements for the RRS system are presented. The paper also describes the hardware and software characteristics of the Multiloop Controllers (MLC) selected for the implementation of the control algorithm. A real time testing verification is performed using the Dynamic Test Bed (DTB) that simulates the KMRR. The static and dynamic responses of the combined system are tested before site commissioning. The test process confirming the acceptability of the control algorithm is discussed and examples of corrective actions made during testing are described.
