TEPCO is looking for
・Benchmark/Case study
・ Tech. proposal
about the challenge below.
Please enter your proposal from SUBMIT button.

【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.

When you propose your ideas, TEPCO CUUSOO account is needed.
* Please be aware of the submission deadline.
