ANSI N15.56:2014

This standard addresses topics concerning the generation and reporting of NDA measurement data regarding holdup deposits, taking into consideration end user data quality objectives. End users of the data may include personnel engaged in nuclear material accounting and safeguards, nuclear criticality safety, waste management, radiological protection, facility characterization, D&D, safety analysis, and licensing activities.
The technical aspects of performing holdup measurements are outside the scope of this document.
Purpose
This consensus standard provides guidance and specifies general provisions concerning the generation and reporting of NDA measurement data regarding holdup deposits. The complexity of NDA holdup measurements and the challenges faced in estimating their measurement uncertainties necessitates specific consideration throughout the document. This Standard provides guidance regarding procedures and method selection, definition of data quality objectives, special word usage standardized to the extent possible, recordkeeping, consistent application of techniques, considerations during calculation of results and uncertainties, and reporting of NDA measurements in a way that is consistent with data quality objectives and end use of the data.
