TEPCO's yearly financial report - drowning in crap

Today Japan's electricity providers released their end-of-year financial reports. All but 2 are in arrears, because of fuel costs for 'thermal' power generation (ie, greenhouse-gas intensive fossil fuels). Costs have been rising both because the importation of LNG has become more expensive in general, and because of the weakening yen. These costs are on top of the extensive expenditure needed to keep their nuclear power plants maintained in the hopes of eventual restart.

TEPCO announced a massive loss of 685 billion yen (6.8 billion dollars). In addition to running their power plants on imported fossil fuels, the electricity provider has also had to deal with the situation at Fukushima (408 million dollars) and pay compensation claims for the evacuees and cleanup (another 11 billion dollars!).

It hardly needs saying that the vast bulk of this expenditure is unnecessary. As the accident neither killed or harmed anybody, evacuation and its associated problems were avoidable. Costs of decommissioning Fukushima Daiichi would of course be considerable, but nothing like the massive losses that have been incurred as a result of Japan turning its back on nuclear power.

Nuclear power -saving millions of lives.

James Hansen was NASA's former point man on climate change and is famed for his testimony on the issue for congressional committees in America. Recently he has become a high-profile advocate for the more widespread adoption of nuclear power, both in the fight against global warming and because of its other obvious advantages over fossil fuels.

The health dangers of burning coal are well-documented; coal pollution kills between 1 and 2 million people annually. On the other hand it has long been known that nuclear power is a much safer way to produce electricity. The number of people killed by nuclear power is orders of magnitude fewer than the number killed by coal, even with the most pessimistic of unproven assumptions.

But until now nobody has tried to estimate the number of lives saved by nuclear power. James Hansen and co-author Pushker Karecha have published a new paper with NASA's Goddard Institute that has put a figure on this. The study is a masterpiece of understated but hugely important findings. The most important finding is that from 1971 until now, nuclear energy has prevented 1.8 million air pollution-related deaths, including 160,000 in Japan alone.

And depending on how many nuclear plants are built and on what fuel it replaces, nuclear power will prevent between 420,000 and 7.04 million deaths by 2050.

These statistics do not take into account damage and deaths caused by climate change. If used to prevent global carbon dioxide emissions by substituting for the burning of coal, nuclear power could be even more effective at death prevention.

This is the kind of story that many so-called environmentalists chose to ignore. Others such as James Hansen have accepted that the only realistic way to both address the world's energy needs and reduce global carbon dioxide emissions is through the embrace of nuclear technology.

More from the Japan Times

The J.Times is turning into a battlefield over the nuclear issue. This may be good for its circulation, but it demonstrates neatly part of the whole problem: the media benefits by keeping an artificial controversy alive. If decisions were made on a rational basis, and newspaper articles were fact-checked against the scientific consensus, there would be no 'battleground'.

So in the last few weeks,

I wrote a letter in reply to this misinformed piece, which makes the common fundamental mistake of supposing that the Fukushima accident is part of Japan's decline, rather than the country's nuclear retreat being the problem.

Nuclear retreat signals decline

In his March 12 Community page article, “Do dire predictions for Japan factor in a rush for the exits?,” Colin P.A. Jones makes a tragic error, an error repeated all too often in the media by those critical of both nuclear power and Japan’s general direction. He sees the government’s response to the Fukushima accident as symptomatic of a deeper malaise in Japan itself. This is wrong for two reasons.
For one, the government’s handling of the situation, despite problems, has been praised by international bodies like the International Atomic Energy Agency. If anything, authorities were overcautious in response to an accident that resulted in zero deaths or injuries. More importantly, far from the Fukushima accident illustrating the government’s misplaced priorities, Japan’s retreat from nuclear power is part of its general decline.
This irony is not lost on observers of Japan’s economic and diplomatic rival, China, which has displayed a much more pragmatic and rational approach to nuclear energy.
Following the accident at Fukushima, that country launched a nationwide safety review. Construction resumed last year, and there are now 30 plants under construction.
China’s nuclear boom is emblematic of the country’s economic and technological growth, and those plants will provide power to the nation’s factories, many of which, by the way, are busy making things once made in Japan. By comparison, Japan seems obsessed with navel-gazing and is even considering a permanent return to the evils of coal, oil and gas.
It’s enough to make anyone “rush for the exits.”



I thought at first the letter had dissappeared without making much of a splash, but in fact it elicicited this counter-letter. The author brings up the issue of '13,000' deaths caused by the evacuation, when in reality people who died in the evacuation were killed not by radiation, but by Fear of Radiation, a very different beast indeed.

Then, like every other person opposed to nuclear power he is faced with the dilemma of how to deal with its ability to generate electricity without producing carbon emissions. In response he chooses to deny the reality of global warming.

When it comes to the issue of climate change, nuclear power has the incredible ability to mitigate global warming while still providing colossal amounts of energy. This is a truly game-changing capability. Every person opposed to nuclear power must either ignore this ability, an indefensible hypocrisy, or argue the route of climate change denialism.

This is a stark choice indeed.

The NRA approves new safety guidelines - Human incredulity tested.

The Japanese Nuclear Regulation Authority today approved a new set of safety guidelines for nuclear power plants, possibly as a test of human wastefulness, overreaction and incredulity.

The draft guidelines, which will be finalised by July, include requirements for the construction of earthquake-proof command centres that have food and supplies to last a week without outside aid. Also required is the installation of filters designed to release pressure from containment vessels but filter out radioactive substances in the case of accident. The most absurd rule (in my view) is that plants build seawalls that can protect the site from the maximum predicted tsunami height.

Plant operators have estimated that upgrading existing reactors to comply with these guidelines will cost about 10.8 billion dollars.

Is it really possible that such overreaction can take place as a consequence of an accident that killed or injured noone? It's like some kind of surreal dream.

The seawall requirement I find to be particularly irksome. It was not the lack of a suitably high seawall that caused the accident at Fukushima Daiichi, it was simply the fact that generators that powered the cooling systems were not placed above flood level, leading to the meltdowns.

Building massive seawalls around every seaside nuclear plant in Japan will achieve nothing except the enrichment of concrete and fossil fuel companies. That Japan is ordering plant operators to prepare for a tsunami event that occurs every 800 years yet is easily mitigated by placing generators on higher ground is bad enough. Worse is the naked disrespect for actual people's lives this demonstrates. If the NRA really prioritized human safety, it would mandate the construction of seawalls around residential areas. In the current plans, the only thing that will happen in case of a disastrous tsunami is that the nuclear plants will be untouched while nearby residents drown in their thousands, which indeed is what happened in Fukushima two years ago.

Perhaps the NRA should consider the human implications of the construction of a 20-metre seawall.

Radioactive ... water!

Wide news coverage today over new leaks from the storage tanks at Fukushima Daiichi.

It seems there have been leaks from two water tanks built to store contaminated water used in the cooling of the three stricken reactors. Last Friday one of the pools leaked 120 tons of contaminated water. Last night a further 3 liters leaked from another storage tank.

The Japan Times weighed in with a fairly measured piece that reported the larger of the two leaks poured 710 billion becquerels of radiation into the environment (apparently the ground under the tank). What they didn't attempt to include however was any assessment of what 710 billion becquerels might mean. Which is, basically, not a lot. Once diluted in the largest body of water on the globe - the Pacific Ocean - this radiation will be far below natural background levels. It will still be detectable over large areas, but only because scientists have the means to measure extraordinarily low concentrations of radioactive particles from artificial sources.

Essentially this leak, like all the other leaks since the end of March 2011, is not an issue that seriously concerns nuclear scientists. What is far more interesting than yet another minor hiccup in a huge industrial clean-up is the usual overreaction on the part of the anti-nuclear press.

Just the comments after this cherry-picked rubbish piece should give pause to any skeptical thinker. There is an unbelievable level of confirmation bias and unwarranted extrapolation that, well, you just don't find on pro-nuclear sites. The level of groupthink is truly depressing.

Fukushima Daiichi without power - kind of

Last night cooling systems at Fukushima Daiichi malfunctioned, leaving the spent fuel pools of reactors 1, 3 and 4 without circulating cooling water for several hours. TEPCO announced that the problem was due to malfunctioning power distribution boards.

According to what I can make of the NHK news site and the TEPCO press release, cooling has been restored to fuel pools 1 and 4; and TEPCO plans to restore power to spent fuel pool 3 this evening and the shared spent fuel pool tomorrow morning.

While temperatures in the affected pools rose slightly, there has been no increase in radiation.

The NHK 7pm news focused on the gap of 3 hours between the loss of power and the announcement to the media by TEPCO 3 hours later, which is being treated as very suspicious in the Japanese media. Interestingly, it also took 3 hours for the Nuclear Regulation Authority to make an announcement, and there was also, somewhat confusingly, video of the NRA chairman Shunichi Tanaka lamenting the delay.

A TEPCO spokesman said "It was considered that the information should be confirmed before being released to the public."

But this is merely the latest incident in a long list of the minor technical issues that have occurred during the clean up of what is, after all, a major industrial accident. I have to tell you, the TEPCO website is not exciting reading.

Of more interest to the skeptical observer is how the incident is being protrayed. This post by ENE 'news' (read: fearmongering) demonstrates my point nicely. It is merely some phrases from a Kyodo news piece cherry picked to provide an impression of imminent destruction. Let's have a closer look:

Kyodo at 2:29p ET: “Tepco hasn’t been able to work out steps to ensure bringing system back online” at Fukushima Daiichi — No ‘major’ changes in radioactivity

The original Kyodo piece has the words 'As of 1.45 a.m.' added onto the beginning of the sentence, which temporally limits the damage to a technical hiccup, instead of giving the impression that TEPCO has been struggling and failing for an extended period (days? weeks?).

The inverted commas around 'major' lend doubt to the word. They give the impression that TEPCO is fudging or lying, that 'no major changes' may in fact be something much more serious and sinister. Neither that ENE piece or any other repeat later Kyodo observation that radiation readings have not been abnormal in any way.

I could go on for hours about that website. After reading it, I am mostly left with the impression that people are way to uncritical. Is it really too difficult, for example, to find and read the original Kyodo article?

The Infinite Promise of Methane Hydrate!

The Prime Minister of Japan Shinzo Abe appeared on NHK 9pm news to answer a few softball questions about economic policy, foreign policy and energy.

Abe is known to be favourable to nuclear power and defended Japan's new Nuclear Regulation Authority, basically saying that the nation's nuclear power plants will be given permission to restart after 'the most rigorous set of safety regulations in the world' have been drawn up and enforced.

He predicted that it would take about 10 years before the nation decided the 'best energy mix'.

There was also the claim that Japan was developing renewable forms of energy and making new sources of energy available such as methane hydrate. He proceeded to talk up methane hydrate quite a bit, and indeed lately this stuff has been getting quite a bit of coverage in the media.

So just what is it and can it help anybody's energy problems?

Methane hydrate is a fossil fuel, originally created by decomposing bacteria, deposits of natural gas trapped within the crystalline structure of frozen water...300 meters or more below the sea.

It is estimated that there is a lot of the stuff around the world - more than the world's estimated reserves of conventional gas, for example. And Japan has a great deal.

The question is whether methane hydrate could be accessed in a commercially viable way. Last Tuesday it was announced by Japan's Ministry of Economy Trade and Industry that a team had succeeded in extracting natural gas from a methane hydrate bed 1300 meters under the sea off the coast of Aichi Prefecture.

Yet there is no promise yet that this new fuel can be economically viable. The best guess I came across was that it would be 4 times the current cost of conventional gas. Not really something to change the world.

Hopefully.

Because it appears that methane hydrate, apart from being an expensive boondoggle and a way for the LDP to divert attention from real energy issues, may be an environmental catastrophe waiting to happen. Methane is highly carbon-intensive, and it is estimated that methane hydrates contain more carbon than all the world's other fossil resources combined.

And while it is hoped that technology may be developed to prevent that carbon reaching the atmosphere, as yet there is no guarantee this is possible.
In any case I will not be holding my breath waiting for methane hydrate to come and rescue Japan. Abe can talk in NHK interviews about 'magic hydrate', renewables, and other fantasies as much as he likes. He knows and we know that Japan's choices come down to ...
 
...conventional fossil fuels versus nuclear.
