我们描述了一种新的方法，用于商业核能生产没有长期的高水平废物流和嬗变的裂变产物和更高的锕系元素的商业核废物使用的热通量的加速器产生的中子在10（16）n/cm 2 s的范围。在这种强度下连续的中子流。其比在大规模热反应器中通常可获得的大大约100倍。由于质子线性加速器技术的最新进展和这里提出的散裂靶减速剂设计，它显得很实用。这种大的热中子通量使得嬗变系统中的废物存量可能比竞争概念小大约100倍。加速器允许系统在低于临界的情况下运行，从而消除了临界事故的可能性。不需要控制棒。这种新的能源生产和废物转化方法的成功实施将消除在地质时间尺度上储存核废物的需要。用钍-232或铀-238生产核能是用来说明商业核能的一般原则，生产时不产生长期的高放射性废物。似乎有足够的钍来满足世界几千年的能源需求。
We describe a new approach for commercial nuclear energy production without a long-term high-level waste stream and for transmutation of both fission product and higher actinide commercial nuclear waste using a thermal flux of accelerator-produced neutrons in the 10(16) n/cm2s range. Continuous neutron fluxes at this intensity. which is approximately 100 times larger than is typically available in a large scale thermal reactor. appear practical, owing to recent advances in proton linear accelerator technology and to the spallation target-moderator design presented here. This large flux of thermal neutrons makes possible a waste inventory in the transmutation system which is smaller by about a factor of 100 than competing concepts. The accelerator allows the system to operate well below criticality so that the possibility for a criticality accident is eliminated. No control rods are required. The successful implementation of this new method for energy generation and waste transmutation would eliminate the need for nuclear waste storage on a geologic time scale. The production of nuclear energy from Th-232 or U-238 is used to illustrate the general principles of commercial nuclear energy, production without long-term high-level waste. There appears to be sufficient thorium to meet the world's energy needs for many millenia.
