Abstract
Software has been developed for \"real-time\" analysis of neutron and gamma data from GRAND-1/ fork measurements on spent-fuel assemblies. Three modules compose the software package. The mod- ules are linked through a database system of files. The first module is part of a general data- base processing code. This module prepares input data files with inventory and correction-factor information for the second module. The second module, called OLAF, operates on a computer attached to the GRAND-1 electronics unit. In this second module, neutron and gamma data from spent-fuel assemblies are analyzed to verify consistency in the facility operator decla- rations for exposure (burnup) and cooling time. From the analysis, potential discrepancies in the measurement data are questioned while equipment is still installed at the facility and is availa- ble for additional measurements. During the measurements, data are written to an output file, called a results file, which can be processed by the third module of the software package. In the third module, printed reports summarizing the data and results are prepared, and neutron and gamma data are written to files that are processed by the Deming curve-fitting code.
