• The neutron emission-rate (NER) method for burnup measurement of a spent LWR fuel bundle submerged in water has been studied by focusing on the spatial higher harmonics effects inevitable for the application of a formula based on the one-point reactor model.<BR>Verification studies of this method have been made through calculations and simulation experiments using the fresh UO<SUB>2</SUB> fuel-rod bundles of nxn arrays (3 ?? n ?? 23, 0.22 ?? k<SUB>eff</SUB> ?? 0.94), and its applicability has been shown for the spent fuel bundle. As a practical example, an actual formula has been given for a spent PWR fuel bundle of 14x14 array of 3.5 wt% initial enrichment and cooling time of 1, 000 days.
