Applicability of AWJ technique for dismantling reactor of the Fukushima Daiichi Nuclear Power Station; Cutting test of imitation of fuel debris and optimization of the cutting condition

Maruyama, Shinichiro*; Watatani, Satoshi*

Based on findings made during recovery works that followed the accident at Three Mile Island Station2, we assume that the reactor internals at the Fukushima Daiichi Nuclear Power Station (1F) have intermixed with melted fuel and confined in limited spaces, they are likely to have complex geometries. Accordingly, abrasive water jet (AWJ) cutting method is considered to be a candidate technique that can be safely and reasonably used for cutting and removing reactor internals. We conducted tests to examine the potential of this technique. We have test for solving the problems of this technique. They are using imitation of fuel debris and optimization of the cutting condition. Based on the results, we confirmed the plan for some of the associated issues, and that AWJ cutting method would be assumed as a candidate technique for removing reactor internals.
