介绍了建于中国原子能科学研究院的氢化锆固态零功率反应堆。该堆采用氢化锆作慢化剂,有机玻璃作反射层,富集度为20％的U_3O_8为燃料。首次临界后,完成了物理特性和安全特性测量,证明它具有稳定性好、灵敏度高等特点。应用该堆成功地进行了人员培训,堆控仪表和实验仪器考验,以及某些应用的预先研究。显示出了它特有的优越性。 The zirconium hydride solid state zero power reactor built in China Institute of Atomic Energy was introduced. The reactor uses zirconium hydride as a moderator, plexiglass as a reflector, enrichment of 20% U_3O_8 as a fuel. After the first criticality, the physical characteristics and safety characteristics were measured, which proves that it has the characteristics of good stability and high sensitivity. The application of the heap successfully conducted personnel training, heap control instrumentation and experimental equipment test, as well as some applications of pre-study. It shows its unique superiority.
