For the decommissioning of nuclear facilities, decontamination of an equipment and a building should be carried out to reduce the release of radioactive material and to facilitate waste management as well. Decontamination of coatings on the floor and the wall of the building and the surface of equipment is also very important issues. Laser decontamination technology has the advantage of very small secondary waste and is suitable for remote decontamination system. In the present experiment, the decontamination with pule laser and its removal ability, characteristics of decomposition and laser transmission by optical fiber have been studied, and the surface decontamination with pulse YAG laser will be available after development of high power laser in near future.
