摘要

为促进中子散射技术在我国的进一步发展

将在一座研究堆上建立一套中子散射实验装置。作为该实验装置的重要组成部分——冷中子源主要包括氢回路系统和氦制冷系统

其中氢回路系统采用单相液氢慢化剂、垂直自然循环的技术模式

这种氢回路具有很好的工作性能和安全特性。氦制冷系统提供的低温氦气在换热器中将冷中子源的全部热载荷带走。本文介绍了反应堆冷中子源的基本原理与布局

详细说明了其主要技术参数。

Abstract

To promote its development in China

a set of Neutron Scattering Experimental Facility (NSEF) will be installed at a new research reactor. A cold neutron source (CNS)

one of the most important components of NSEF

is a mono-phase liquid hydrogen moderator of vertical thermosiphon type. Nice working capacity and safety are main advantages of the CNS with a sub-cooled liquid hydrogen thermosiphon. Cooling helium from refrigerator removes the total heat load from the CNS in the heat exchanger. In the paper

an introduction of the principle and arrangement of the CNS is given

and technical parameters of the CNS are described in detail.
