DECONTAMINATION EXPERIMENT for FLOOR of FUKUSHIMA DAIIHI REACTOR BUILDINGS

摘要

The accident on Fukushima Daiichi Nuclear Power Plant was occurred by the TSUNAMI that generated from Great East Japan Earthquake happened in 11 March 2011. For restoration of the accident, it is necessary for operators to enter and work in the reactor buildings. However, the dose rate in the reactor buildings is extremely high because of heavy contamination. Therefore, it was tried to assume procedure that contamination reached to reactor buildings floors. Rough decontamination experiments were performed to ensure the safety of workers in a course of emergency response. The experiment of decontamination has been conduct with several reagents of decontamination. In this paper, results of experiment of decontamination are reported.
