Keywords:Physical decontamination, Laser, Abolition measure, Clearance-izing, Gouging

Development of the gouging decontamination construction method using line laser is furthered for the purpose of clearance-izing of radioactive waste for amount-of-resources reduction of the radioactive waste generated at the time of maintenance, reconstruction, and the abolition measure of a commercial reactor.
Here, the result of the excision capacity evaluation test about this decontamination construction method and the decontamination performance evaluation test (Cold examination) using imitation contamination is reported.
