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.
壓水堆核電站所采用汽輪機(jī)為飽和蒸汽型汽輪機(jī),其低壓缸末級(jí)葉片很容易發(fā)生水蝕,如果葉片出現(xiàn)問題導(dǎo)致故障會(huì)給核反應(yīng)堆運(yùn)行造成運(yùn)行瞬態(tài)事件,因此對(duì)核電站安全性、經(jīng)濟(jì)性都有著嚴(yán)重威脅。
