PROBLEM TO BE SOLVED: To provide an execution method of an activated concrete cutting work capable of reducing the amount of a radiation discharged into the sea or the like as the whole work, and having less effect on the general public. SOLUTION: This execution method of the activated concrete cutting work has a wet cutting process S1 for cutting the activated concrete, while injecting cooling water into a cutting part; a solid/liquid separation treatment process S2 for separating cutting waste liquid 1 including activated concrete sludge generated at the wet cutting process S1 time into a solid portion 3 including a radioactive material and a filtrate 2 wherein the radioactive material is dissolved; and a neutralization treatment process S3 for neutralizing the filtrate 2 into a neutralized filtrate 4. In the method, the filtrate 2 generated in the solid/liquid separation treatment process S2 is used as the cooling water at the wet cutting process S1 time. COPYRIGHT: (C)2006,JPO&NCIPI
