US4848278A - Nuclear steam generator sludge

Sludge-removing fluid lances are moved simultaneously toward the center of a tube bundle in a steam generator through diametrically opposite lance ports. Fluid-blocking suction dams are placed in the peripheral lane of the steam generator at diametrically opposite inspection ports from which fluid-entrained sludge is removed. All four of the ports are spaced apart by 90°.
