Performance Support System for Monitoring in the McMaster University Nuclear Reactor

The purpose of this paper is to present a design methodology that can be employed to develop computerized radiation monitoring systems for technology insertion into non-computerized human-machine systems. The methodology seeks to hybridize and exploit the benefits of several diverse disciplines including nuclear engineering, computer science, health physics, real-time system design, human-machine interaction, computer-human interface, and software engineering, in the realization of a Performance Support System (PSS). The focus for combining these disciplines is on the implementation of a specific application: The Iodine Monitoring and Advising System (IMAS), a computerized embedded system for the MNR (McMaster Nuclear Reactor) I¹²⁵ production facility. IMAS uses radiation monitoring techniques and human factor concepts to provide nuclear reactor operators with a computerized monitoring alarm facility. The migration from a crude and inflexible spill detector to an intelligent performance support system is documented
