HIGH-FIDELITY MODELING OF SPENT FUEL ASSEMBLIES FOR ADVANCED NDA INSTRUMENT TESTINGS

摘要

Testing of the advanced NDA instruments developed under the NGSI-SF project requires high-fidelity, well-characterized spent fuel assembly models to quantify the instrument performance. These assembly models have been generated using ORIGAMI, as described in this paper. The unique features of the ORIGAMI have been also demonstrated. Comparisons to one set of experimental data have also been discussed. More NDA instrument testing is planned at Clab in the near future, and the data continue to be used to benchmark the calculations.
