This paper presents about conceptual designs of Advanced Recycling Reactor (ARR) focusing on enhancement in transuranics (TRU) burning and americium (Am) transmutation. The design has been conducted in the context of the Global Nuclear Energy Partnership (GNEP) seeking to close nuclear fuel cycle in ways that reduce proliferation risks, reduce the nuclear waste in the US and further improve global energy security. This study strives to enhance the TRU burning and the Am transmutation, assuming the development of related technologies in this study, while the ARR based on mature technologies was designed in the previous study. It has followed that the provided TRU burning core is designed to burn TRU at 28 kg/TWthh, by adding moderator pins of B4C (Enriched B-11) and the Am transmutation core will be able to transmute Am at 34 kg/TWthh, by locating Am blanket of AmN around the TRU burning core. It indicates that these concepts improve TRU burning by 40-50% than the previous core and can transmute Am effectively, keeping the void reactivity acceptable. 相似文献

应用LabVIEW的虚拟仪器平台进行了故障电弧断路器(AFCI)的设计和研制,主要包括数据采集装置和任意信号发生器两个部分。数据采集装置基于USB9203板卡,具有高精度和高采样率;任意信号发生器基于USB9263板卡,发生的信号不受频率和周期性等因素的限制,并能随时从正常工作状态切换至电弧故障状态,更真实地模拟实际故障情况。利用该虚拟仪器平台采集电弧故障信号,经相应的数据处理后由信号发生器发出,并应用于AFCI装置的检测,取得了良好的实验效果。 相似文献
