#Fukushima I Nuke Plant Worker's Perspective on the Debris Dropping Accident at Reactor 3 SFP: Normal Project Management System Doesn't Work on an Abnormal Situation

"Happy11311" has been tweeting from Fukushima I Nuclear Power Plant since the March 11, 2011 triple disaster of earthquake, tsunami and nuclear accident. He tweeted his take on the fuel handling machine mast that dropped into the Reactor 3 Spent Fuel Pool with a big splash a few days ago.

He says the work was carried out even when it shouldn't have been, because the contractor(s) was under pressure to catch up.

He also says that the work is done by remote control, but it needs workers in tungsten vests right on the platforms surrounding the Reactor 3 building, as they have to visually monitor the work to make sure everything is going safely.

From his tweets on February 10, 2013 (my translation):


As I tweeted before, removing the debris on the Reactor 3 operating floor is extremely difficult. Since the Reactor 3 operating floor has high radiation levels, unlike on the Reactor 4 building, workers cannot go up there to remove the debris. The actual debris removal [for Reactor 3] is carried out from a location far enough to avoid radiation exposure by remote control, but there are cases where the camera images from different angles are not enough.


In order to compliment the remote work, visual inspection is necessary. So, workers wearing heavy tungsten vests take turns to go up on the platform, and communicate with the remote control operators to carry out the work. Workers who go up on the platform are exposed to significant amount of radiation. So now, I want to look back on that incident the other day.


It was snowing, and the work must have been very awkward and hard to do. In fact, my group canceled almost all the work that day. In that condition, I'm thinking it must have been hard to see. Camera images may have been blurry, and the [face]masks and telescopes of the workers on the platforms may have fogged or covered with water drops.


So what I'm wondering is why they were doing the work in bad weather like that. Particularly when they have been doing the work extremely carefully on the Reactor 3 operating floor ever since they dropped a steel beam. So it's just my hypothesis. But that day, other construction groups were also doing the work using cranes.


I remember I was surprised to hear the work was being carried out that day, when I arrived at the plant. In retrospect, the work that was being done in the bad weather was either behind schedule or urgent.


Installing the cover over the ALPS [multi-nuclide removal system] was one. Construction of facilities in front of the plant's main gate to move the functions of J-Village [staging area for the plant work] was another. And debris removal on the operating floor of Reactor 3. They were all urgent jobs. When I think about them, I see that there are problems other than technical problems. There are two problems. One is the hiring period of the plant workers and radiation exposure.


The other is this determination to catch up on the work that is behind schedule. Or [I should say] to make [the workers or subcontractors] stick to the schedule when each work is unique in a sense that you don't know what happens until you actually do the work. I often say slow and steady wins the race, do the work diligently and safely. But no matter how the workers think, it won't happen unless TEPCO and primary contractors put that into practice.


TEPCO has the schedule that it has submitted to the national government. Contractors have submitted their schedules to TEPCO. If the work is behind these schedules, the media and people in Japan will attack them, and that's the pressure. The pressure will then be on the workers, creating the situation where a day's quota has to be met even if there is a risk potential.


As to the debris falling into the [spent fuel] pool, I don't think it was just a matter of technique. I suspect it was the result of the wrong assessment of the situation, including the weather, to determine whether the work could be done safely and securely. In my opinion, workers shouldn't be the ones to decide, but it should be TEPCO and the primary contractors to responsibly decide, taking all possible situations into consideration.


Even when workers think "It's difficult in this condition, we can't do it", it is difficult to articulate that to their supervisors, contractors, or TEPCO managers in charge. In such cases, workers are afraid, cannot perform to the best of their abilities and skills, and that often results in troubles. I have done that in the past, and I have many regrets.


The work should not be about taking the chances (gamble). I want TEPCO and primary contractors to make such decisions that would allow workers to safely and securely carry out the work to the best of their abilities and skills. I don't think TEPCO should shift the responsibility to the subcontractors, or the subcontractors shift the responsibility to the workers.


For sure, adherence to the schedule, cost-cutting, quality control, safety management, they are all important. But this work will last for decades, and the jobs are all special which you don't know how they turn out until you actually do them. A general, normal project management system shouldn't be applied to Fuku-I (1F). Even a small trouble will blow up the near-term schedule.

Minister of Economy, Trade and Industry Motegi in the Abe administration will turn deaf ears to Happy11311's plea. He unilaterally declared that decommissioning of Fukushima I reactors should be done ahead of schedule. For reasons only known to himself. Probably to prove to the world that three melted-down reactors on the wrecked nuclear power plant mean nothing to the Japanese, and taking 3, 4 decades to decommission even the regular nuclear reactors is for wimps.

Motegi is most welcome to join in at Fukushima.

On second thoughts, workers like Happy11311 have no need for a McKinsey management consultant.

To go mind-numbingly normally through an unprecedented disaster is what Japan has proved itself to be very good at. Like the national government telling Toshiba and TEPCO they would need a permit to transport batteries on the highway (and they followed orders), or telling the US that a crane from Australia was not licensed to travel on a Japanese road.

Remember also that they completely forgot to turn on the teleconferencing system at the Prime Minister's Official Residence, set up specifically for a nuclear disaster like this. And what were they doing instead? Telephone and fax, and person to person communication which mostly did not happen.

hi admin
interesting post.. reblogged to

sorry not to have been covering stuff this last week but appear to be under cyber warfare.. currently using a usb linux system that seems effective, so far!!

and so back to work!! :)
i hate drones too! :(

Happy must realize he is a pawn and TEPCO with its prime subcontractors purposely insulating themselves from direct responsibilities by hiring layers and layers of sub contractors down to so called independent contractors (day laborers). This is SOP allowed by the current Japanese government.

Personally I don't see how they could hurt SPF 3 anymore, only unless the water drained out to empty.

The work is important and necessary but keeping the situation from getting any worse could be wiped out by a large earthquake at anytime and already (3) melted cores are uncontainable, continuously contaminating the environment.

If you emptied the 4 SFPs you would still be back to square one on melted core cleanup. But the SFPs must be emptied to eliminate those threats.

I'm sorry, I'm starting to think ole Happy is just pure fictitious Tepco damage control. He's never reported anything we didn't see first. Why is that? He always has a pat answer, downplaying the event. "Cigarette fire"... "Boiler smoking at the csfp", but never gives any details.He never seems to get rotated out of Daiichi either. He must be radiation proof.

"appear to be under cyber warfare"

I wonder whom it could be. Let us see.
My opinion is that it could be "Ashursts Australia and Paladin mining".

A petition to save and :

I have gazed into the monolith that is corporate earth and declared "My God, it is all so full of it's own Bullshit!"

They want to import chinese workers to mine here in canada, and the russians are purportedly actively mining montana for U.

anon at 6:41PM attacking Happy, you are about 1.5 years late. That meme is tired.

Quote from above: "My opinion is that it could be "....""

My opinion is that it is not "Ashursts Australia and Paladin mining", they are professionals.
