铀氢锆（ＵＺｒＨｘ）堆芯具有很大的瞬发负反应性温度系数。本文所介绍的１００ＭＷ铀氢锆小型动力堆ＩＮＳＵＲＥ—１００正体现了该种燃料堆芯的这一独特优点。在系统布置上采用一体化方案，余热排出采取非能动的自然循环方式。这种固有安全动力堆有很好的前景，是一种理想的热电联供堆。目前，我国已掌握了铀氢锆元件的制造技术，并在铀氢锆（ＵＺｒＨｘ）脉冲堆上得到实际应用。
UZHH core has a large instantaneous temperature coefficient of negative reactivity. The 100MW Uranium Hydrogen Zirconium Mini-Power Station INSURE-100 presented in this article is demonstrating this unique advantage of this fuel core. In the system layout on the integration program, exhaust heat to take a passive natural circulation. This intrinsically safe power reactor has good prospects and is an ideal CHP reactor. At present, our country has mastered the manufacturing technology of uranium, hydrogen and zirconium components and got practical application in UZrHx pulse stack.
