Former PM Naoto Kan says nuclear power makes little economic sense, must end


Staff Writer

Although the first reactor in Japan to be fired up in two years went online last month, former Prime Minister Naoto Kan said Wednesday that Japan needs to seek a nuclear-free path.

This is a lesson the country has learned from the Fukushima nuclear disaster, said Kan, who was prime minister when the Fukushima No. 1 plant was hit by a huge quake and tsunami on March 11, 2011.

“I’m absolutely sure that there will no longer be nuclear power by the end of this century. This is because it doesn’t make sense economically, and enough energy can be provided without it,” Kan said in a lecture to foreign residents in Tokyo.

While reactor 1 at the Sendai plant in Kagoshima Prefecture was restarted in August, Japan has survived the past few summers without nuclear power, Kan said.

He added that although the current government is still promoting nuclear power, Japan has seen an increase of renewable energy since the Fukushima accident, especially from solar panels.

He said nuclear power was believed to be a cheap source of energy, but it is actually expensive, considering the cost of decommissioning and managing nuclear waste.

Kan also shared his experience of visiting Olkiluoto Nuclear Power Plant in Finland, where a final nuclear waste repository is being constructed. There, he was told it would take 100,000 years for the radiation of nuclear waste to descend to the same level of the uranium that exists in the natural environment.

Using nuclear power, Kan said, means increasing the amount of dangerous waste that will trouble future generations, adding that this is why other former prime ministers such as Junichiro Koizumi and Morihiro Hosokawa are also voicing their wish to end Japan’s dependence on it.

    I don’t see anything in the article about Kan calling reactors unsafe. I guess Kan is finding new reasons to oppose his old bugaboo. Are we finally moving on from simple scare tactics?

    Let’s back up a bit. I seem to remember Kan ordering perfectly functioning nuclear power plants to shut down after 3.11.11 for no reason whatsoever. And NOW he is saying that they are not commercially viable? Well, would they be commercially viable if everyone had not panicked and shut them down 4.5 years ago? We really don’t know. Would they be viable if utilities were not forced to add demonstrably needless but expensive new functions after 3.11? Again, we don’t know. I have not seen a single definitive examination of the accounting involved for a single nuclear power plant in Japan, and I bet Kan has not either. Are we so distrustful of utilities that we accept this failed politician as an authority on the management of electrical utilities?

    It looks to me as though Kan broke the system, and now he is criticizing the system because it is broken. I think he has found his new career.

    Using nuclear power is insane. It is too expensive and too unsafe. I live on the West Coast of California. We have been hit by Fukushima’s radiation, both in the air and the sea water. Radioactive water is still being dumped by TEPCO into the Pacific Ocean. I am scared. We humans have pushed this planet and the life on it to the breaking point with climate change. Is nuclear power to be the coup de gras in this horrific reality humans have created? Shut the plants down, everywhere and lets go with green power. Green power will downgrade our current lifestyle, but at least we’ll be living.

    You know, all snark aside, if Kan had come out a week after 3.11 and said that the business case for nuclear makes no sense, I could give him respect.
    Or if all of the Asahi/JT minion reporters had bothered to actually investigate the business case for nuclear the last 4.5 years instead of trying to panic everyone with an over the shoulder play by play of TEPCO in Fukushima, I could respect that.
    Or if all the people posting the InfoWars/Bizarro “radiation is going to kill you” and “utility managers are ghouls” could suck it up and just concentrate on the facts and find actual malfeasance, I could respect Kan and all the rest for speaking their conscience.

    But I don’t live in that world. In my world, I have a bunch of people who were sincerely fighting CO2 emissions before 3.11 and sincerely trying to make the best of a very bad situation after 3.11. And my lights are still on. And they saved my life by sticking with the stricken plant instead of pointing fingers from day one, as everyone else has.

    Sorry. I would really like to know more about the financial case against nuclear, but if all I am going to get is Kan and Greenpeace and the Union of Concerned Scientists, then I know I won’t be getting the straight story. They shot their credibility over and over. And people will choose to ignore them.

    And finally, let me shed some light.
    After 3.11, while everyone else was scrambling to learn about radiation, I scrambled to learn about utilities. I feel pretty confident that I know more about them than Kan does, and it is not just because Kan is a goober.

    The fact is that nuclear in Japan as we know it is probably on its way out. Not because of costs, though, but because the utilities just don’t need new nuclear plants. They want to use what they have and not waste them. There are strong accounting-related reasons for doing so, not ideology. I am pretty sure that if all the anti-nuclear people sat down with all the utilities and government today and made an agreement to let the utilities finish up using the plants they have now without a lot of hassle, in exchange for huge investments in wind or something, well, that might be acceptable. It is the best deal anti-nuclear people are going to get right now… because….

    The brutal irony is that utilities will turn to coal and a little natural gas, but only if it is cheap. Germany did. And all the protests will start all over again. Everyone will be worse off. The world will be worse off. I am so sure of this that I predict that environmentalists will start promoting nuclear power soon. Not tomorrow, but soon. Greenpeace has gone silent on nuclear issues. Anyone notice that? I think I hear their funding drying up. Kan is almost always on the wrong side of important issues, so he is a good signal too.

    And that is why the utilities are sticking to their guns. They seem intransigent and unyielding, but they know the best outcome and the alternatives. Sounds elitist, but this is WHAT THEY DO. We are the amateurs, and they are the pros.

    The most cost-effective path forward for energy generation in Japan is to get those shuttered nuclear power plants back on line as soon as possible. They are already built, so those infrastructure costs are already behind us. The last thing Japan should do (or Germany, or any of us) is burn fossil fuels. The writing is on the wall with global warming, and fossil fuels will only worsen the situation. Kan is being irresponsible, transparently pandering to a skittish public.

    He’s right. nuclear is 4 times the cost of solar or wind, out of fuel in 10 years, and deadly to millions using LNT.

    Solar and wind are now available cheaper than any other sources. Before gov breaks

    The IAEA says that we will have uranium shortages starting in 2025, then getting worse fast.
    “As we look to the future, presently known resources
    fall short of demand.”

    Designers of the BWR intended it to fail safely, as explained by an informant of mine:

    BWRs use the water in the torus as a filtering mechanism for the vessel. The containment doesn’t have direct filters. The “mobile” fission products are those that are either gaseous, or water soluable. Gaseous are the noble gasses, Xenon and Krypton, etc. Noble means they don’t interact with things. So no real way to filter, but also not a biological hazard. Water soluable, Iodine and Cesium are the main ones. By blowing the reactor steam through the torus water, you quench the water and capture all of the water soluable isotopes.

    If “they” are the office of the Japanese prime minister of the time, their ruinous, and irresponsible, delay in allowing this venting prevented that capture, greatly increasing the release of radioactivity. The thing still failed safely — no leaf was made to fall by radiation, no worker got radiation sickness — but a lot less cleanly than it might have without Chief Engineer Kan’s help.

    And as a result of that help, he’s now flitting around, presumably not on just his pension, expressing antinuclear concern. And the civil service that remains, in his country, has had many billions of dollars in fossil fuel tax revenue windfall.

    The last thing Japan needs is another Fukushima: it would destroy Japan.
    The first reactor they tried to restart was hit with
    earthquakes, a huge storm, a volcano, and coolant piping leaks.

    Fukushima flooded again last week.

    There is no worse place on earth for nuclear power plants, than the Rim of Fire Japan.

    Stop wasting time, and money on restarting deadly,expensive, short of fuel in 10 years, nuclear power.

    Offshore wind can provide more energy than japan country uses. It’s predictable day to

    Solar PV on rooftops, parking lots, and road covering can supply more energy than Japan uses. It’s very predictable, and mostly coincides with summer peak,
    greatly reducing peak generator needs.

    That will drive Japan’s fossil use way down. Phase out any old inflexible baseload plants,
    and replace them with load following, gap filling diesels and turbines. If you insist on coal, gassify it and use it in flexible turbines or diesels.

    Turn your wastes into fuels. Not incineration, that’s too wasteful. Carbon neutral relatively
    cleaner hydrocarbons are what solar and wind need for long term backup and reserve. We will need hydrocarbon fuels for transportation, and chemical feedstock too.

    Once enough solar and wind cover most of the total energy demand in total, they will produce more peak power than demand and the excess electricity will find uses
    such as synthesizing fuels. This is the “battery” solar and wind
    need. We already have the tech and infrastructure for using
    hydrocarbon liquid and gas fuels.

    Hydrocarbons are not the problem, excess fossils hydrocarbons are. Waste to fuels is neutral, and with biochar can be massively carbon negative.

    Japan cannot afford to stay with fossil and nuclear, both are running short of fuels very soon, and that will lead to even more price shocks.

    Only renewables can provide the energy the world needs. Renewable is already available cheaper than fossil or nuclear. It has free infinite fuel forever, much
    cleaner, safer, carbon negative, needs zero land, water, rare earths,
    and is 100% recyclable and sustainable.
