Fukushima Nuclear Worker Accidentally Toggles Off Cooling Pumps
An anonymous reader writes "A Tepco employee carelessly pressed a button shutting off cooling pumps that serve the spent fuel pool in reactor #4 — thankfully a backup kicked in before any critical consequences resulted. The question remains just how vulnerable to simple mistakes (such as a single button push) are these spent fuel pools, filled nearly to capacity as they are with over 12,000 spent fuel rods? From the article: 'The latest incident is another reminder of the precarious state of the Fukushima plant, which has suffered a series of mishaps and accidents this year. Earlier this year, Tepco lost power to cool spent uranium fuel rods at the Fukushima Daiichi plant after a rat tripped an electrical wire.'"
since a backup system kicked in to prevent any critical consequences.
It was homer simpson who did it.
Am I imagining things, or does it sound like a nuclear plant is being operated by a company without the barest idea of how to do that?
Accidentally flipping off the cooling pumps in a nuclear plant sounds like something which shouldn't even be physically possible.
Lost at C:>. Found at C.
This isn't another example of how precarious the situation at the Fukushima Daiichi plant is, but one of how massive the incompetence of TEPCO is that they keep having 'incident' after 'incident'. Even long before Fukushima Daiichi TEPCO's safety record was beyond frightening.
That the Japanese government a) allows TEPCO to 'clean up' Fukushima and b) refuses any foreign help shows that the problem with Fukushima is and always has been a political one.

That seems like the sort of function that should be designed with a multi-step process to execute, to eliminate precisely that kind of error. How in the world did that get implemented?
'The latest incident is another reminder of the precarious state of the Fukushima plant...'
So something unexpected occurred, but automatic backups stepped in and prevented any negative consequences. While the plant may or may not be in a precarious state, this is hardly the example to be using for a FUD article. Hell, change the spin around and it could be used in a TEPCO press release showing how far they've come in stabilizing the situation.
Everything is better with chainsaws.
A human made a mistake which was caught and corrected by an engineered system. Seems like a non-story.
Fukusima will never end.
but that didn't help the Three Mile Island operators any, now, did it?
you have to be at the top of your game to keep the dragons at bay in a nuke plant.
there is so much fouled up at Fukushima Daiichi that the training manuals and game plans are straight out the window and into the fire. this means you can't follow the manuals any more. and THAT means that a one-man job needs to be cross-checked at every step by somebody who is in position to monitor the stage being worked on.
and THAT... means the same old team can easily be outclassed by the breeding dragons in the lairs. we have already seen TEPCO stumbling around so many times like it takes two members of the shore patrol to drag them back to the ship for Captain's Mast.
TEPCO is, has not been for a long time, and will never be in a position to manage the catastrophe they set forth. this is no place for yes-men who are slaves to 40-year-old process.
if this is supposed to be a new economy, how come they still want my old fashioned money?
normally, that would be a proper reaction. but we're talking about a place that put their "main backups", the most critical safety system outside of containment, underground. asking to be flooded. I'd be very suspect about any of their backup systems
We've instilled a belief in the general public that scientists and engineers can pull of miracles, and that we know more than them. Science in movies is often almost magical, and people expect our encyclopedic knowledge of esoteric technical systems to translate into quick and easy solutions to difficult problems. About a decade ago, I found myself giving a presentation to a group of nuclear scientists. It was a nerve-wracking experience for a young computer geek, and I presented the team with two alternatives for warehousing environmental data at their facility. There was a brief debate before the most senior member of the group spoke up and said, "You're the expert. What do you recommend?" It didn't matter that there were ten people in the room with PhDs and decades of experience; everyone naturally wants someone else to provide them with an easy path to the best answer. At that point, they were all primed to accept a recommendation from the young whippersnapper who could think quickly on his feet (and was armed with a laser pointer, I might add) I gave them the best recommendations I could, and many were eventually accepted. But deep down I realized that I could quite easily have led them astray at that point. I'm acutely aware that there must be dozens of people like me who have been working at Fukushima for over a year now; the so-called "experts" on the ground who are trying to make the best choices possible. Their job is unenviable because they're facing contamination on a huge scale and many decisions were made in haste in an attempt to limit the scope of the catastrophe. That will make everything harder for those involved in the containment and remediation in the coming decades.
Didn't he write The Iliad?
Any insufficiently advanced magic is indistinguishable from technology.
Means you have days to respond, not minutes. And a backup kicked in quickly, accompanied (I presume) with a lot of alarms and a very strong reprimand from management for "testing an interlock" Why is this news?
Blaming nature for the foreseeable consequences of building a nuclear reactor with inadequate safety precautions in a tsunami zone is nonsense. TEPCO is 100% responsible for the ongoing disaster, not nature.
One of their safety guys forgot to eat breakfast that morning. He relied on his backup reserve of stored fat to get him through until lunchtime, but that's not good enough, he could have kept forgetting to eat and what then? He runs out of stored reserves and starves to death, right there in the middle of conducting a safety examination.
Why if enough of the safety guys forgot to eat, every single one of them could die, and then there would be NONE left. No way in hell am I relying on a backup system that was designed by trial and error evolution.
