Fukushima radiation levels at highest level since 2011 meltdown

The facility’s operator, Tokyo Electric Power (Tepco), said atmospheric readings as high as 530 sieverts an hour had been recorded inside the containment vessel of reactor

The recent reading, described by some experts as “unimaginable”, is far higher than the previous record of 73 sieverts an hour in that part of the reactor.

A single dose of one sievert is enough to cause radiation sickness and nausea; 5 sieverts would kill half those exposed to it within a month, and a single dose of 10 sieverts would prove fatal within weeks.

A remote-controlled robot that Tepco intends to send into the No 2 reactor’s containment vessel is designed to withstand exposure to a total of 1,000 sieverts, meaning it would survive for less than two hours before malfunctioning.

In December, the government said the estimated cost of decommissioning the plant and decontaminating the surrounding area, as well as paying compensation and storing radioactive waste, had risen to 21.5tn yen (£150bn), nearly double an estimate released in 2013.

Wow, this is why I hate Nuke power. It's not safe at all. We need to get rid of it.

nuclear power is probably the only reason the world hasn't obliterated itself yet. as bad as nuclear war would be, the aftermath of meltdowns across the Northern Hemisphere would render most of the planet completely uninhabitable (if not all of it, i would think there might be some safe areas in the SHEM like NZ, Australia, etc). can't win a war if your enemy has dozens of nuclear power plants that douse your country in radiation regardless of the outcome.

There is also a 1 meter hole in the floor of reactor 2. Fun times

Looks like the radiation continues to increase and looks like several food chains are collapsing in the pacific with fish populations dropping dramatically.

Crazy how we use a technology we literally can't control

i wouldn't say can't control, as under normal circumstances we can control the reactions.

 

The problems come in when extreme conditions start (like in this case a 10m Tsunami after a 9.0 quake with poor planing for a sinking seawall), and we forget to have such facilities prepared for such potential conditions as part of a cost/benefit analysis. that lack of preparedness is what causes these disasters, and also brings costs we can't compute in worst-case scenarios.

 

If anything from disasters like this, Chernyobyl, and even Three Mile Island, we should be learning how to make facilities more resilient if we want to use them. There are some potential ideas to make this happen. But those ideas are generally way to expensive to power companies in the short term (even if in the long term they may not be bad). Until our utilities are willing to fork out the bucks to use the safer designs and have the safeguards for the most extreme cases, we just can't build new nuclear power plants, much less keep plants we currently have going for anything in the longer term like we are currently.

Saying that nuke fuel is worse than the unknown effects of hundreds of years of FF burning is lol

Libs are fucking stupid. No wonder they all have gvt jobs.

How many people have died from nuclear energy as compared to fossil fuels?  There is no "safe" way to power our society using either one imo but to think fossil fuels are any less lethal is a joke.

It's not something we should be using atm. A attack on a  nuke plant or plants or a big nat disaster and vast parts of the county would be unlivable and millions would die. Also, we would see genetic mutations in many northern hemisphere species.


Oh, and we are entering the age of cyber warfare. And these will the golden targets.

Just because we have been lucky does not me we should be ignorant.

Climate change is slow and with tech growing exponentially and AI around the corner. We will solve any issues it causes to our long term future.

Fukushima is an unmitigated catastrophe, and it's effects are probably far worse than we're told.  They can't even locate the fuel, much less get it.  Nuclear power is awesome as long as it works as anticipated.  But the problems are twofold:  We often don't keep the infrastructure updated, which leads to greater risk of failure/compromise.  And we only build them to withstand the things we've thought of, and sometimes even then, poor planning opens the door to disaster.

Sure, it's cleaner than fossil fuels, but we have these plants all over the place.  Suppose something happened to cause a few/several/many of them to go Fukushima?  The risk of that is low, but probably higher than we think.  Even with a low risk of failure, the outcome of annihilation has now been brought to the table.

It's time to switch to solar and battery world wide.

Problem is Japan is the worst possible place to put nuclear reactors- the entire nation is on a fault line.  You wouldn't want to put a reactor near the San Andreas fault either.  The fact that we have a geothermal plant there is pretty bad too.

Our nuclear reactor architecture needs to be updated.  And yes there is always concern for an attack, but gas and oil pipelines are also vulnerable- heck some of them explode all on their own!  And the environmental damage caused by drilling and spillages cannot be overstated.

 

The point is we have to wean our way off of fossil fuels, and nuclear is an important part of that.

EDITORIAL: TEPCO bungles it again in dealing with Fukushima tainted water

October 9, 2018 at 14:05 JST
 

Disturbing new revelations about increasing amounts of radioactive water at the Fukushima No. 1 nuclear power plant have undoubtedly further darkened the already dim prospects for solving this tricky and complicated challenge.

Tokyo Electric Power Co. (TEPCO), the operator of the nuclear plant destroyed by the 2011 earthquake and tsunami disaster, has said the filtering system to decontaminate the polluted water, known as ALPS (advanced liquid processing system), has failed to remove such radioactive elements as strontium 90 and radioactive iodine.

On Sept. 28, the utility acknowledged that about 80 percent of the water in storage tanks for ALPS-treated water on the plant premises exceeded government standards for radioactive materials.

TEPCO previously claimed that the ALPS system could remove all radioactive elements except for tritium, a mildly radioactive isotope of hydrogen.

the solution to pollution is dilution.

It’s what they used to do unfortunately. They failed to realize radioactive waste bioaccumulates, it doesn’t dilute. Just keep investing in solar and find ways to recycle the PV waste.
