Abstract

When total volume control is applied to toxicity in nuclear waste management it becomes a limiting factor for the permittable total operating capacity of nuclear reactors. An alternative conceptual scenario is proposed, aimed at toxicity reduction through partitioning and transmutation. Specifically, the electricity generation capacity could be increased by transmutation of ⁹⁰Sr and ¹³⁷Cs. Simultaneously, the cooling time before disposal is reduced to 50 years from the 300 years required by existing scenarios, such as the accelerator-driven system. Finally, the scenario is also found to be feasible in terms of energy balance and cost, using an Li(d,xn) reaction neutron source with a deuteron accelerator for transmutation.

摘要

当总量控制应用于核废物管理中的毒性时，它成为核反应堆允许的总运行容量的限制因素。提出了另一种概念方案，旨在通过分区和嬗变降低毒性。^{具体来说，可以通过90} Sr 和¹³⁷ Cs的嬗变来增加发电能力。同时，处置前的冷却时间从现有场景（例如加速器驱动系统）所需的 300 年减少到 50 年。最后，还发现该方案在能量平衡和成本方面是可行的，使用带有氘核加速器的 Li(d,xn) 反应中子源进行嬗变。
