Title: Evaluation of an integrated holdup measurement system using the GGH formalism with the M{sup 3}CA

Abstract

Nuclear facilities need portable, automated tools based on gamma-ray spectroscopy to perform plantwide assays of special nuclear materials (SNM) deposited as holdup in processing equipment. These assays satisfy such nuclear material control functions as obtaining or verifying SNM inventory quantities, assuring safe operating conditions, and quantifying SNM for decontamination and decommissioning. A new, integrated holdup measurement system designed to meet these requirements has been evaluated quantitatively for holdup assays. The hardware for the integrated holdup measurement system consists of a compact gamma-ray detector with collimation and shielding, a self-contained portable gamma-ray spectroscopy instrument, and a palm-size programmable control and data-storage unit. The application software, called HMSII (Holdup Measurement System II) masks the sophistication of the hardware and data analysis with a simple user interface. The heart of the integrated holdup measurement system is the generalized-geometry holdup (GGH) calibration and analysis formalism. The GGH formalism is based on the simplifying assumptions that each of hundreds of holdup deposit geometries in the facility can be interpreted as one of three simple geometric models (point, line, or area) to reduce the calibration and analysis effort to manageable proportions. Results obtained over a 4-yr period will be presented. Because of the reproducibility of setupmore » and data treatment under HMSII automation, it is straightforward to repeat the assays of static equipment over extended periods of time with multiple users. This new integrated measurement system improves the precision and reliability of holdup measurements.« less
