However, a number of incidents identified by the NRC (Nuclear Regulatory Commission) since 1980s catalysed the US nuclear industry to adopt standard precautions to guard against counterfeit items. The purpose of this paper is to suggest the NFC (near field communication) based equipment qualification management system preventing counterfeit and fraudulent items. The NEQM (NFC based equipment qualification management) system works with the support of legacy systems such as PMS (procurement management system) and FMS (facility management system).展开更多
