A DISCUSSION OF TECHNIQUES USED IN DEFINING THE INTERACTIVE MEASUREMENT EVALUATION AND CONTROL SYSTEM AT ROCKY FLATS

This paper describes both the general methodology used to study the current needs for a measurement control and evaluation system at Rocky Flats Plant and the recommendations for implementation into the Interaceive Measurement Evaluation and Control System (IMECS). The study resulted in a clear assessment of the current system and recommendations for the system which will be its replacement. To arrive at the recommendations, the authors used a formal analysis approach that is based on an in-depth study of the measurement evaluation and control problems and user needs. The problems and needs were defined by interviews with present and potential users of this kind of system throughout the nuclear industry. Some of the recommendations are to provide: - Timely sample measurement feedback - Representative measurement error estimates - A history data base of sample measurements To meet the user needs, the new system will: - Be interactive with user selection menus - Use standards which cover the range of application - Facilitate historical analysis of sample data and bookkeeping The implementation of this program is projected to be more cost effective than the current program. Also included are the authors' recommendations to those involved in the design of a system of similar large magnitude.
