Measurement control workshop instructional materials

Abstract

An essential element in an effective nuclear materials control and accountability (MC&A) program is the measurement of the nuclear material as it is received, moved, processed and shipped. Quality measurement systems and methodologies determine the accuracy of the accountability values. Implementation of a measurement control program is essential to ensure that the measurement systems and methodologies perform as expected. A measurement control program also allows for a determination of the level of confidence in the accounting values. This report is a compilation of workshop materials consisting of lectures on various aspects of measurement control, including calibration, basic statistics and measurement models, analysis of measurement method qualification data, control charts, inventory difference analysis, and measurement control for specific measurement systems. The objectives of these materials are to identify, study, and discuss best practices in measurement and measurement control for the accountability of nuclear material. Presentation is envisioned to be through classroom instruction and discussion related to physical and error measurement models, uncertainty estimation, measurement control, and other areas of interest related to measurements. Several practical and hands-on exercises are included for demonstration of the various measurement concepts contained in the lecture/discussion sessions. Mode of Instruction The suggested mode of instruction for these materials is lecture, demonstrations, and participant-led practical exercises. Participants Participants attending this workshop should currently, or in the near future, be responsible for measurements and/or measurement control or material accountability at their facilities. It is suggested that the ideal participant pool consist of several MC&A "teams" that include MC&A specialists, measurement experts, and statisticians.
