Fuel removal device installed at meltdown-hit Fukushima reactor

Workers at Japan's crippled Fukushima Daiichi nuclear power plant have installed a device to remove nuclear fuel from a meltdown-hit reactor nearly seven years after the crisis was sparked by a tsunami, a spokesman said Monday.

The plant's operator, Tokyo Electric Power Co (TEPCO), said it started putting a crane on the roof of unit No. 3 on Sunday to extract a total of 566 rods from its pool.

It will be the first removal of fuel rods from one of the three reactors that melted down when the tsunami struck the plant in March 2011.

TEPCO has already removed from unit No. 4 whose was empty when the tsunami crashed ashore.

It plans to start removing rods from the fuel pool of unit No. 3 "sometime around the middle of the next fiscal year" starting in April 2018, TEPCO spokesman Atsushi Sugiyama said.

It has yet to start removing any fuel from the reactor cores of the three meltdown-hit units, as the complicated decommissioning process is expected to last for decades.

The magnitude 9.0 quake, which struck under the Pacific Ocean, and the tsunami it spawned left about 18,500 people dead or missing and overwhelmed cooling systems at the plant, causing the world's worst nuclear disaster since Chernobyl in 1986.

The quake and also caused extensive damage to homes and property while radiation spread over a wide area, with more than 450,000 people evacuating in the immediate aftermath.

These are NOT fuel rods from the reactor, but from the spend fuel pool.

Meanwhile, Mexico has signed a PV contract for power at 1.7 CENTS/kWh!!

"Even the worst nuclear accidents result in far fewer deaths than the normal operation of fossil fuel power plants."
Fukushima: zero deaths from radiation exposure.
Meanwhile, at COP 23, through Energiewende, wind and solar are confirmed to be a trillion-euro fiasco in terms of CO2 reduction and that have only served to favor coal and other fossil fuels to keep lights on when wind isn't blowing or sun isn't shining and which air pollution kills 9 millions of people every year worldwide.

"While nuclear and hydro are strongly correlated with decarbonization of energy at aggregated national levels, solar and wind are not."

Before the bankruptcy of Westinghouse, the Vogtle nuke plants were scheduled to produce power at over 15 cents/kWh.

How much have they wasted on it so far? Ten billion dollars?

If it is built, it will cost ratepayers ten times the PV price for power for 50 years to pay it off!!!

BTW, my PV panels now power the house and TWO EVs. I bought a Tesla Model S, P-85.

Is your car nuclear? Why not?

Meanwhile, American nuclear plants need huge subsidies now, even more than before, to remain operating, and Trump's folk are looking for ways to do it, while taking support from the renewables upon which we will base our future power system.

Conservative corruption.

Wind and solar were promised by faux-greens as a powerful lethal weapon against Climate Change. After trillions of dollars spent worldwide, intermittent renewables are a shameful fiasco in terms of CO₂ reduction, a tremendous ecological disaster, that have served to make mankind ever more stuck on coal and gas(fracking) to keep lights on when wind isn't blowing or sun isn't shining or during prolonged droughts.
Carbon-free nuclear is worth the price as the only scaleable way to stop Climate Change.
China(one of major manufacturer of windmills and solar panels) is already on the right track:
"China's Nuclear Power Appetite to Offset Western Decline"
"The country is set to cut its reliance on fossil fuels"

Gosh, Willie, now we have two electric cars to drive on sunshine. The around-town car is the e-Golf, and the bigger car is the Tesla Model S, P-85, which we took to Sonoma today.

My PV system may have to be expanded to cover the house and both cars as well.

How are you guys doing, back there in the 20th Century?

George thinks that buying a few gadgets and spouting a bunch of slogans from the 1970s will make him young again.

You're old george. Nothings gonna change that.

Welcome to the 21st century.
