last stage blades

Water erosion occurs frequently at the last stage blades of saturated steam turbine in PWR power plant. The erosion in blades would induce unexpected transient during plant operation, threatening the safety and economy of plant.
壓水堆核電站所採用汽輪機爲飽和蒸汽型汽輪機,其低壓缸末級葉片很容易發生水蝕,如果葉片出現問題導致故障會給核反應堆運行造成運行瞬態事件,因此對核電站安全性、經濟性都有著嚴重威脇。
