Robot begins removing Fukushima nuclear plant’s melted fuel.
(www.voanews.com)
Robot clearly never watched the ending of Fallout 3 about letting the humans do it instead.
Or let a super mutant do it for you if you've bought the add-on
Without the addon there was a robot companion that would refuse to go in, just like Fawkes does before you get the dlc. After you get the dlc both companions will go in, and be fine afterwards, because radiation doesn't affect them.
Much like Fawkes the robot companion said some BS about not robbing you of your destiny before you install that particular dlc.
Human Robots
How radioactive is the robot afterwards?
That kinda depends on exactly what it is removed and how. Being exposed to radiation doesn't make you radioactive. Ingesting radioactive particles will kinda make you radioactive until those particles reach their end of life and fission. I would be surprised if the robot is actually radioactive once it is done, but I wouldn't be at all surprised to find out that the structural integrity of the robot has been compromised due to exposure to radiation.

Good question
Be really interested to know what it's made out of. Had a coworker who used to work in forgings and did some stuff that got sent to nuclear plants, they said that they had really strict requirements on material compositions, specifically needed to ensure that the (think it was steel, may have been something else) material had basically no traces of cobalt in it because the cobalt would becomes radioactive over the service life.
There are several factors to consider when choosing materials in a nuclear plant. For things that aren’t in direct proximity to the reactor core, neutron activation (becoming radioactive) is less of a concern. Aluminum produces hydrogen gas when exposed to boric acid, which presents an explosion risk. Certain chemical compounds can cause corrosion to plant equipment, even a Sharpie marker could corrode a valve or pipe and cause issues over the 50 year life span of a plant.
That's really interesting about Sharpies, I would have never known that about Sharpies.
Edit: I accidentally the word "never" above.
Depends heavily on the kind (and intensity) of radiation. Beta (electron/positron) and gamma (photon) generally won't, but neutron and alpha can. Many of the atoms that become radioactive will rapidly decay, and that's one of the mechanisms behind the impact to structural integrity.
Shortly after I returned to the States from Fukushima (a little bit after the disaster), I was taking an emergency response course on radioactivity. Everybody there got to use a Geiger counter on themselves and their belongings and various things in the room. The only thing that set it off was the purse I had brought back with me.
Anecdotal, obviously, and it wasn't highly radioactive, but I did get rid of the purse.
Let's just say, you wouldn't want to stand near it.
Itself, not very, but any dust or flakes that land on it definitely will be. It only takes very small particles.
Usually, equipment like that is abandoned in place. Radiation has weakened its parts, and decontamination is complex and time-consuming for something you can't just hose and scrub down.
We're just gonna set up a vat of molten metal and send it out Terminator 2 style. /s
See, totally harmless accident. Just give it another hundred years and the place will be good as new.
When reading about dungeness reactor i learned that even reactors that haven't melted down also take about a hundred years to decommission safely.
Another interesting stat I heard on a podcast is that the coal industry has proven much more deadly than the nuclear industry in terms of human lives lost.
It doesn't take a hundred years, but a couple of decades and it's hugely expensive. And nobody knows what to do with the waste.
Everyone that does their research knows what to do with it. https://world-nuclear.org/information-library/nuclear-fuel-cycle/fuel-recycling/processing-of-used-nuclear-fuel
That's some really cool technology you got there, that can reprocess radioactive waste from decommissioning nuclear plants. You know, reactor vessels, bio shields, all the plumbing etc. Please point me to a source on how that technology works.
Nuclear reprocessing is the chemical separation of fission products and actinides from spent nuclear fuel.
Did you even read what I wrote before?
Like I said below, it’s basically recycling, which also doesn’t make the waste disappear. I’m with you on this one, but you also did ask how reprocessing works, so there’s that.
My question was specifically how reprocessing the stuff other than fuel would work. And it was a rhetorical question because it obviously doesn't.
You either just treat them like normal buildings, treat them like tourist buildings, or just sell them to Holtec.
plumbing
Do you really think that out of the millions of demolished buildings, none had toilets‽
You really have absolutely no idea what you're talking about.
I live within two hours of a decommissioned nuclear power plant and 10 seconds of a sink.
But isn’t the amount you can recycle limited?
Ooooh. Is there a catch? Are the Fukushima spent fuel caskets all fully recycled?
But what about their 307cu³ and counting of spent fuel?
The care and maintenance stage is part of the Nuclear Decommissioning Authority (NDA) decommissioning strategy and spans an 80+ year period. This waiting period allows for radiation levels within the reactor core to decline and helps to facilitate a smoother demolition process. Dungeness A is due to enter the care and maintenance phase in 2027. Demolition of reactor buildings and final site clearance is planned for 2088 to 2098

It's an amazing place. I visited last month. You can overlook the power station from a nearby lighthouse.
Fantastic. Just kick the can down the road and make it some future generations' problem. Great technology!
Sadly that's what the human race does. It's nothing unique to nuclear power.
It still baffles me, for example, that with all this technology, we still generate all this rubbish which we then bury in the ground. And we all know it. We all buy things in disposable packaging. We are all complicit.
Do you really have trouble understanding the difference between nuclear waste and regular waste?
It's much better than the alternative, yes cancer rates shot up and a huge area of once beautiful and productive land is contaminated but if we had rooftop solar then rich corporations wouldn't be able to manipulate us with price spikes and lock us into being helpless without them.
The rich need to have power over us and centralized power generation controlled by the ultra wealthy is the only option that let's them have that dominamce so every propaganda bot must ignore all the safety risks, spiraling economic costs, and political bullshit so they can push for it and divert money from.far more viable and effective alternatives.
Manufacturing of solar panels produces a different kind of contamination, though—it's just not located at the point of power generation. Wind is probably a bit better, with fewer exotic chemicals required, but "rooftop wind" isn't exactly a common catchphrase.
Wind Turbine's problems is we have to replace the blades every 3-7 years depending on the model and there is no good way to recycle or break down the fiberglasse components. So every every 3-7 years you have 3 XL tractor truck trailer size turbine blades going into landfills.
Wind and Solar are still good, don't get me wrong, but lets not pretend they have no downsides or drawbacks.
More or less everyone is allowed to return to their homes as of this year. Even the radiation in the direct vicinity of the plant is nearly nearly down to pre-accident levels
If I know my bad Japanese movies correctly, the radiation is going to mutate that robot until it is 80 feet tall and only Gamera will be able to stop it.
