摘要:我国第一座实验核动力堆创建于1970年,经过10年的间歇满功率运行,于1980年停堆卸料。本文介绍在该堆堆芯上完成的两个重要物理实验。第一个实验是燃耗前的一比一零功率物理模拟实验,介绍了卡棒准则试验,停堆裕度测定和通量分布测量等3个实验项目。对硼可燃毒物管的4种堆芯布置方案,给出含提棒方式研究的共计16次通量分布测量结果和4张通量分布图。
第二个实验是燃耗末的物理实验。介绍了分批测定新、旧硼可燃毒物管次临界反应性比(。/ o.》的实验概况。实验是在具有强放射性动力堆堆芯现场进行的。中子探测使用了抗大场干扰的涂硼组合计数管。反应性测量采用双探测器互相关频谱分析法(CCFS)和脉冲中子源法(PNS)两种。文中
给出5批硼管反应性比(△0。/△p)测量结果。数据证明:反射层区确管燃耗深度低于调节棒区。关键调:卡棒准则;热管因子;可燃毒物;提棒方式;反应性匹配

Abstract: The first experimental nuclear power reactor in China was started up in the year 1970. After operating at full power intermittently for ten years, the reactor was shut down and its fuel unloaded in 1980. Our two important experiments presented here were completed before and after the fuel burn-up in this reactor core. The first experiment is a physical simulation experiment on a 1 : 1 scaled zero power reactor before the reactor's startup, this paper shows the completed testing items : control rod hang-up criterion test, shutdown margin measurement and neutron flux distribution measurement for searching the maximum hot channel factor. This paper shows how to select arrangement patterns of boron-added burnable poison tube in the reactor core, and what can be
