1　运行概况1997年原型微堆开堆运行频繁,实验安排相当饱满,除了每周一必须进行的堆水和池水净化之外,全年的科研、活化分析等工作均不间断进行。全年运行状态见表1。2　科研、生产和活化分析1997年在原型微堆上主要完成的任务有:中子活化分析样品辐照、核探测器考验、堆物理实 1 Operational Overview In 1997, the prototype micropiles were frequently operated in open reactor and the experimental arrangement was rather full. Apart from the water and pond water purification which must be carried out every Monday, the annual scientific research and activation analysis were carried out continuously. The operational status of the whole year is shown in Table 1.2. Research, Production and Activation Analysis The main tasks accomplished in the prototype microduct in 1997 are: irradiation of neutron activation analysis sample, nuclear detector test, physical reactor
