Abstract
Two computer programs are described: (1) the International Atomic Energy Agency (IAEA) Neutron Coincidence Counting (INCC) program and (2) the DEMING curve-fitting program. The INCC program is an IAEA version of the Los Alamos Neutron Coincidence Counting (NCC) code. The DEMING program is an upgrade of earlier Windows® and DOS codes with the same name. The versions described are INCC 3.00 and DEMING 1.11. The INCC and DEMING codes provide inspectors with the software support needed to perform calibration and verification measurements with all of the neutron coincidence counting systems used in IAEA inspections for the nondestructive assay of plutonium and uranium.
