法国90万千瓦核电站每座堆有三台51B型蒸汽发生器。这种蒸汽发生器为立式自然循环倒 U 管形,下部为热交换管束,上部为汽水分离器,管束材料为因科镍-600。U 形管全胀到管板上并与堆焊层焊接。管束呈正方形排列。沿高度有8块支撑板,材料为不锈钢,上面为拉制的四叶孔,管束的防振装置可消除机械共振和水力激振。 France 90 kilowatts nuclear power plants each pile has three 51B steam generator. This steam generator vertical inverted U-shaped natural circulation, the lower part of the heat exchange tube bundle, the upper part of the steam separator, the tube bundle material is Inconel-600. The U-tube is fully expanded to the tube plate and welded to the overlay. Tube bundle arranged in a square. There are eight support plates along the height, the material is stainless steel, the top of the drawn four-hole, tube bundle of anti-vibration device to eliminate mechanical resonance and hydraulic excitation.
