Description
Utilization of the standard ANSI/ANS-8.6-1983 'Safety in Conducting Subcritical Neutron Measurements in Situ' is discussed as a means for putting together a criticality safety evaluation for a fissile process where some information about the process is not known and/or when sparse computational validation data exists to achieve the necessary safety margins. Past and present ideas for utilizing the standard are given. A subset of the operational guidance contained in ANSI/ANS-8.6-1983 is discussed. A generic example for performing an in situ subcritical neutron multiplication measurement is given. The generic example illustrates multiple methods for analyzing the data with the intent of making the criticality safety case for attaining the required safety margin for the process. (authors)
