我国第一座脉冲堆稳态运行试验

Operational Tests at Steady State in the First Pulsed Reactor of China

本文简要地介绍了我国第一座脉冲堆稳态运行试验方法和设施,给出了冷态和热态以及不同功率下的临界棒位,并给出了反应性、中子通量、功率系数、平衡氙毒和碘坑的测量结果,提供了一批有价值的工程试验数据。本堆实现了1MW 稳态功率运行,进行了连续72小时满功率运行,对反应堆的控制、保护、测量仪器及各系统和设备进行了考验。试运行结果表明:本堆性能良好,各项指标均已达到了设计要求。

The paper briefly introduces the operational tests methodsand facilities at steady state of the first pulsed reactor of Chi-na.The critical positions of the control rods in cold and hot re-actor core and various power condition are given The reactivi-ty,neutron flux,power coefficient,equilibrium Xenon poisoningand Iodic pit are measured and the results are shown.A numberof valuable engineering test data are provided.The pulsed reactor has realized 1MW steady-state operation,it has gone a steady-state trail run at full power for 72 hours.Reactor control and protection systems,instrumentation,andvarious systems and equipments were tested.The reactor showsgood performances in compliance with the design specification.
