反应堆启堆用智能化外推临界装置堆上考验试验

摘要

The Intelligent Extrapolation Criticality Device is used for automatic counting and automatic extrapolation during the criticality experiment on the reactor. Test must be performed on the zero - power reactor or other reactor before the Device is used. The paper describes the test situation and test results of the Device on the zero - power reactor. The test results show that the Device has the function of automatic counting and automatic extrapolation, the deviation of the extrapolation data is small, and it can satisfy the requirements of physical startup on the reactor.%反应堆启堆用智能化外推临界装置用于反应堆临界试验过程中进行自动计数和自动外推临界.该装置在用于外推临界试验之前必须在零功率反应堆或其它反应堆上进行考验试验.论文叙述了研制的反应堆启堆用智能化外推临界装置在零功率堆上考验试验的情况及试验结果.试验结果表明:智能化外推临界装置具有自动计数和自动外推临界的功能,且外推结果偏差小,满足反应堆物理启动试验的要求.
