#Fukushima I Nuke Plant: Humans Will Enter Reactor 3 Again

TEPCO announced on July 8 that the human workers will enter the reactor building of the Reactor 3 in preparation for the nitrogen injection. The humans will go in the afternoon on July 8 to the high radiation area (50 millisieverts/hour) of the reactor building to survey the condition of the location where TEPCO wants to use for nitrogen injection. The work is expected to last about 10 minutes.

If nitrogen injection was really necessary there wouldn't be all these delays. I think it's just a feel good thing to show people how 'safe' they are.

Let's not forget that there is over 300 tonnes of melted nuclear fuel rod in the basements of three nuclear reactors at Fukushima.

Three hundred tonnes...

Robbie001 sez:

I have to agree this is just more window dressing. If they had a melt-out and neither the RPV or PC are holding pressure a nitrogen purge is just "going through the motions". The fact that they are still worried about hydrogen generation after 3 months of feeble cooling just goes to show how little they have actually achieved in all that time. The water treatment plant is just the beginning of a lot of unintended consequences nature has for the Japanese in the future. Cleaning up the ocean of contaminated water isn't anything compared to the effort that will be required to round up the loose fuel in not one but three popped reactors. TEPCO trying to brag on their water treatment solution is like a weakling bragging that he's got his bloody nose under control while the bully is still beating them up.

It has been 25 years at Chernobyl and they still don't have a clue as to how to move, store or finally process the ruined fuel. Contrary to popular belief Chernobyl isn't "buried" nor is the problem solved. It is actually in worse condition today due to sever deterioration of the original structure.

It's like Areva said in the last article the Kan't administration needs to have some good news so they can send everyone home and forget this ever happened. If I was old Natto (beanhead) Kan't I would move everyone home now. Heck, people well outside the area are living in radiation levels as high if not higher than the exclusion zone he could use that as a selling point "you can run but you Kan't hide".

Those poor TEPCO 'workers'! Murder!
And who will oppose killer-employers??
Are they engineers or just day-laborers picked up off the street?

??? No one is going to clean up ocean. It's impossibly large.

> compared to the effort that will be required to round up the loose fuel in not one but three popped reactors.

For what purpose would you want to collect that fuel?

If you think that after it is removed, the buildings will be safe to visit for any prolonged time, then you are mistaken. The radiation in reactor hall now is not coming from the corium per se, but from condensed radioactive water, dust, etc.

What are you going to do with the collected fuel? Store as radwaste?

Newsflash: you can store it where it is located right now.

IOW: after a few more months of cooling, install passive air cooling (heat pipes+radiators), then fill all lower-level rooms in reactor buildings with concrete. Bingo: it will be safe for hundreds of years.

> TEPCO trying to brag on their water treatment solution is like a weakling bragging

I'm not a fan of TEPCO, but give them credit where it is due: having water treatment system operational in such a difficult situation is a good thing.
