Abstract

The work presented in this paper focuses on the first 10 years (2011–2020) of Godiva IV operations at the National Criticality Experiments Research Center (NCERC). Godiva IV is a fast burst critical assembly constructed of approximately 65 kg of highly enriched uranium fuel alloyed with 1.5% molybdenum for strength. Godiva is one of the last such critical assemblies in the United States and can be used for studies of super-prompt-critical behavior as well as irradiations and demonstrations. An overview of the startup of Godiva IV at NCERC is given followed by a summary of the experiments performed utilizing Godiva IV over the first 10 years of operation at NCERC.

摘要

本文介绍的工作重点关注国家临界性实验研究中心 (NCERC) Godiva IV 运营的前 10 年（2011-2020 年）。Godiva IV 是一种快速爆破临界组件，由大约 65 公斤的高浓缩铀燃料构成，其中含有 1.5% 的钼以提高强度。Godiva 是美国最后一批此类关键组件之一，可用于研究超快速关键行为以及辐射和演示。概述了在 NCERC 启动 Godiva IV，然后总结了在 NCERC 运营的前 10 年中利用 Godiva IV 进行的实验。
