Nuclear Power Still the Worst

Nuclear power is one of the few things - along with smallpox and climate change - that really is even worse than its most hysterical opponents claim.

Zandar:

As I mentioned this morning, today is the anniversary of the Fukushima disaster in Japan, which resulted in tens of thousands dead, tens of thousands more displaced, and a nuclear plant meltdown that will continue to cause detrimental environmental effects for generations.

Reactor number one at Fukushima Daiichi is still so hot that five years later, robots still can't enter.

The robots sent in to find highly radioactive fuel at Fukushima's nuclear reactors have “died”; a subterranean "ice wall" around the crippled plant meant to stop groundwater from becoming contaminated has yet to be finished. And authorities still don’t know how to dispose of highly radioactive water stored in an ever mounting number of tanks around the site. 

Five years ago, one of the worst earthquakes in history triggered a 10-meter high tsunami that crashed into the Fukushima Daiichi nuclear power station causing multiple meltdowns. Nearly 19,000 people were killed or left missing and 160,000 lost their homes and livelihoods in the quake and tsunami. 

Today, the radiation at the Fukushima plant is still so powerful it has proven impossible to get into its bowels to find and remove the extremely dangerous blobs of melted fuel rods, weighing hundreds of tonnes. Five robots sent into the reactors have failed to return. 

The plant's operator, Tokyo Electric Power Co (Tepco)  has made some progress, such as removing hundreds of spent fuel roads in one damaged building. But the technology needed to establish the location of the melted fuel rods in the other three reactors at the plant has not been developed. 

“It is extremely difficult to access the inside of the nuclear plant," Naohiro Masuda, Tepco's head of decommissioning said in an interview. "The biggest obstacle is the radiation.” 

The fuel rods melted through their containment vessels in the reactors, and no one knows exactly where they are now. This part of the plant is so dangerous to humans, Tepco has been developing robots, which can swim under water and negotiate obstacles in damaged tunnels and piping to search for the melted fuel rods. 

But as soon as they get close to the reactors, the radiation destroys their wiring and renders them useless, causing long delays, Masuda said. 

Each robot has to be custom-built for each building.“It takes two years to develop a single-function robot,” Masuda said.

And so the cleanup will continue, probably for the rest of the lives of the people there working to decontaminate the site now.  It's a massive environmental disaster that should have been the end, worldwide, of nuclear power technology.  It's not.  And there are hundreds more potential Fukushima meltdowns waiting to happen.  We do this to ourselves and see the results, and we still do it.

We only get one planet, and we've killed it multiple times over.

But wait!  Nuclear power gets worse.  As has been  true from the birth of nuclear power, nuke plants are never, ever, EVER cost-effective.  They always cost more and charge their customers more than any other kind of electricity generation - even solar and wind in the infancy of those technologies when they cost a mint, but nuclear cost a dozen mints.

But don't be relieved - there's one way to make nuclear energy economical: make the government - that would be you and me as taxpayers, but not the profit-taking nuke industry - subsidize it.

Joe Romm at Think Progress:

In the modern era, nuclear power plants have almost always become more and more expensive over time. They have a “negative learning curve” — along with massive delays and cost overruns in market economies. This is confirmed both by recent studies and by the ongoing cost escalations of nuclear plants around the world, as I’ll detail in this post.

The cost escalation curse of nuclear power

“Ever since the completion of the first wave of nuclear reactors in 1970, and continuing with the ongoing construction of new reactors in Europe, nuclear power seems to be doomed with the curse of cost escalation,” read one 2015 journal article, “Revisiting the Cost Escalation Curse of Nuclear Power.”

In the United States, the cost of Georgia Power’s newest twin Vogtle reactors may top initial estimates of $14 billion and reach $21 billion, according to recent Georgia Public Service Commission testimony. Of course, the first two Vogtle Units begun in 1971 took 18 years to build (a decade over schedule) at a final price of $9 billion — ten times the original price tag. BloombergBusiness wrote last fall, “Even as sympathetic an observer as John Rowe [former chair of the U.S.’s largest nuclear utility] warns that the new units at Vogtle will be uneconomical when — or if — they’re completed.”

 Nuclear power: worse than coal, worse than fracking, worse than Saudi oil, worse than anything.
