Abstract

The accelerator-driven thermal neutron source (TNS) at SARAF is under the advanced design stage, to provide an accelerator-based substitution to existing neutron imaging and diffraction utilities of the IRR1 aging research reactor. A challenging task of the system design is to provide a safe and maintainable coupling of 40 MeV deuteron beam and a 200 kW power liquid metal target with a compact light-water moderator and reflector assembly. The verification process of the mechanical design is performed through Monte-Carlo simulations over the detailed CAD models. We outline the method of verification of neutron production and safety requirements over the detailed system design and highlight the advantages of this approach.

SARAF慢化中子源的机械设计验证

SARAF的加速器驱动热中子源（TNS）正处于高级设计阶段，以提供基于加速器的替代IRR1老化研究反应堆现有的中子成像和衍射实用程序。系统设计的一项具有挑战性的任务是提供40MeV氘核束和200kW功率液态金属靶的安全和可维护的耦合，该目标具有紧凑的轻水慢化剂和反射器组件。机械设计的验证过程是通过对详细CAD模型的蒙特卡罗模拟进行的。我们概述了中子生产和安全要求的验证方法，而不是详细的系统设计，并强调了这种方法的优势。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
