Actual Fukushima worker talks: water purifying system has never worked

Following up this article 220 tons of highly radioactive water leaked and a part of it leaked to the sea

The water purifying system has never worked properly.

It was urgently constructed, the whole system can’t stand anymore.

These are the tweets of actual Fukushima worker Happy20790.

He explains how it is on the sight.

The contaminated water leaks a lot recently. This time, it went out of the “building” so it was reported but actually it happens frequently.

I called it “a building”, but it’s actually a temporary tent on a temporary concrete basement. It leaked from the first operation, so they made a tiny dam in it. Maybe it’s only 20cm high.

I don’t get into the tent recently because it’s too radioactive, but I used to pump up leaked contaminated water. The contaminated water emits a lot of beta ray, so you need to be careful.

This time, Tepco’s spokesman said it was 110 mSv/h, but it is higher at some points.

The concrete basement was constructed really urgently. They built the tent even before the concrete dried so it got cracked already. Other tent may have the same problems too.

Unlike our ordinary contract, makers only set the facility, they don’t take responsibility of handing or maintenance.

As I tweeted before, this water purifying system is not a long-lasting system. It is a temporary system without proper planning process. In order to release cooling water to the sea, we must install more proper facility.

Now the gutter is directly connected to the sea. They must be shut down or a dam must be made. Currently every time it rains, radiation on the ground and radiation stuck to the plants flow into the sea directly.

Makers and workers are already withdrawing from Fukushima plants, but Tepco has no long term plan. They need to predict the future risk and prevent it from happening in advance.
