9 hr hydrogen explodes within the containment structure, causing a pressure spike on the control room gauges and an audible thud.
9小时反应堆安全壳内发生氢气爆炸,随着一声巨响,控制室仪表盘上显示出压力峰值。
proper unloader setting allows a small amount of continuous bypass (approximately 5% of total flow) to minimize the pressure spike and compensate for nozzle wear.
