OSTI ID:6737283
This patent describes a method of removing sludge from steam generator interior surfaces. It comprises: generating a source of coherent light energy being laser light; accessing the interior surfaces of the steam generator with a fiberoptic transmission pipe; transmitting the laser light into sid steam generator sludge surface through the fiberoptic transmission pipe; focusing the laser light from the fiberoptic transmission pipe onto the sludge surface; and vaporizing the sludge with the energy of the focused light.
