摘要

热处理是一种新兴技术,对实施封闭式核燃料循环至关重要。其特点是利用高温熔盐介质从乏核燃料中的裂变产物中提取和回收锕系元素。尽管该技术大有可为,但它也带来了扩散问题,凸显了强有力的保障措施的必要性。虽然数十年来建立的水基后处理设施保障框架提供了基本参考,但由于热处理所带来的独特挑战,有必要采取量身定制的方法。在这些担忧中,热处理被认为是一种可行的核废料管理策略,其研究重点越来越多地放在熔盐系统中的选择性和有效性上。本文仔细研究了热法处理所固有的扩散风险,阐述了必要的保障措施,并评估了热法处理的可行性,特别是在美国和韩国之间的 123 协议范围内的可行性。

Technical Overview of Pyro-processing and Policy Considerations

Technical Overview of Pyro-processing and Policy Considerations

Pyro-processing is an emerging technology crucial to the implementation of a closed nuclear fuel cycle. It is distinguished by its method of extracting and recycling actinides from fission products in spent nuclear fuels, utilizing high-temperature molten salt media. Despite its promise, the technology poses proliferation concerns that underscores the imperative for robust safeguards. While the safeguarding framework for aqueous reprocessing facilities that has been established over decades offers a foundational reference, the unique challenges posed by Pyro-processing necessitate a tailored approach. Amid these concerns, Pyro-processing is heralded as a viable strategy for nuclear waste management, with research increasingly focusing on its selectivity and efficacy within molten salt systems. This paper scrutinizes the proliferation risks inherent in Pyro-processing, delineates the requisite safeguards, and evaluates the feasibility of Pyro-processing, especially within the purview of the 123 Agreements between the United States and South Korea.

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
