Abstract
Alternative techniques to neutron detection by Helium-3 for nuclear security and safeguards systems are necessary to be developed because Helium-3 shortage is serious. With the support of the Japanese government (MEXT ; Ministry of Education, Culture, Sports, Science & Technology), the Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (“ISCN”, hereafter) of Japan Atomic Energy Agency (JAEA) has started an R&D project of ZnS scintillation neutron detectors for non-destructive assay of Pu in Fresh MOX fuel and other types of nuclear material for use in safeguards verification. Here we present the master plan of the R&D project and the feasibility study on a non-destructive assay (“NDA”, hereafter) of nuclear fuel with ZnS detectors by using Monte Carlo code, MVP
