THE ROLE OF FUNCTION ANALYSIS IN THE ACR CONTROL CENTRE DESIGN

摘要

An essential aspect of control centre design is the need to characterize: (1) plant functions and their inter-relationships to support the achievement of operational goals, and (2) roles for humans and automation in sharing and exchanging the execution of functions across all operational phases. Function analysis is a design activity that has been internationally accepted as an approach to satisfy this need. It is recognized as a fundamental and necessary component in the systematic approach to control centre design and is carried out early in the design process. A function analysis can provide a clear basis for: (1) the control centre design for the purposes of design team communication, and customer or regulatory review, (2) the control centre display and control systems, (3) the staffing and layout requirements of the control centre, (4) assessing the completeness of control centre displays and controls prior and supplementary to mock-up walkthroughs or simulator evaluations, and (5) the design of operating procedures and training programs. This paper will explore the role for function analysis in supporting the design of the control centre. The development of the ACR control room will be used as an illustrative context for the discussion. The paper will also discuss the merits of using function analysis in a goal- or function-based approach resulting in a more robust, operationally compatible, and cost-effective design over the life of the plant. Two former papers have previously outlined, the evolution in AECL's application approach and lessons learned in applying function analysis in support of control room design [Ref.1,2]. This paper provides the most recent update to this progression in application refinement.
