【摘要】 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。更多还原

【Abstract】 This paper presents 100MW UZrHx power reactor INSURE-100 with some passive safetyfeatures. One of its marked charateristic is haveing great prompt negtive fuel temperature coefficient of reactivity. Whole primary system is enclosed in reactor vessel-integrateed layout.Primary fluid flow circule is natural circulation. Core residual heat removing is carried out bytwo secondary side natural circulation systems-passive safety. So, the prospect of this smalltype reactor would be very good. It is suitable for utilizing of heat-electricity cogeneration.Nowadays, NPIC has capability to manufacture UZrHx fuel and applied on its first Pulsed Reactor at NPIC.更多还原
