医院中子照射器装置于2007年开始建造,2008年12月完成了反应堆厂房建造,2009年3月完成了相关系统的安装和调试。2009年12月7日首次达到临界,2010年1月22日达到满功率运行。物理调试结果表明,医院中子照射器反应堆最终后备反应性为4.2 mk,满功率最大可连续运行时间为12 h,功率波动小于0.3%;4.2 mk反应性释放实验表明,反应堆在229 s时达到85.7 kW的最大峰值功率,随后,由于燃料元件多普勒效应和慢化剂的负温度效应会非能动地把功率限制在允许的安全水平之下,反应堆具有良好的固有安全特性。
The hospital neutron irradiator installation was started in 2007, the reactor plant was completed in December 2008, and the installation and commissioning of the related system was completed in March 2009. December 7, 2009 for the first time to reach the critical January 22, 2010 reached full power operation. The results of physical tests showed that the final backup reactivity of the hospital neutron irradiation reactor was 4.2 mk, the maximum continuous operation time of full power was 12 h and the power fluctuation was less than 0.3%. 4.2 mk reactivity release experiment showed that the reactor reached at 229 s With a maximum peak power of 85.7 kW, the reactor has good inherent safety characteristics due to the fact that the fuel element Doppler effect and the negative temperature effect of the moderator can not actively limit the power below the permissible safety level.
