【Challenge and Current Status】
In the south area of Unit 1 R/B ground floor, access to and securing of areas for PCV investigation and fuel debris retrieval are very hard due to high radiation from Atmospheric Control (AC) system pipe which is contaminated inside.
Before cutting and removing the high contaminated pipes, it is necessary to check the hydrogen concentration inside the pipe.
We would like to identify whether there are technology or insight on hydrogen detection from outside of the pipe or evaluation methodology for hydrogen concentration.
