Delays, Confusion as Toshiba Reports $6 Billion Nuclear Hit and Slides To Loss (reuters.com)

Makiko Yamazaki, reporting for Reuters: After a day of delays and confusion, Japan's Toshiba said on Tuesday it expected to book a $6.3 billion hit to its U.S. nuclear unit, a writedown that wipes out its shareholder equity and will drag the group to a full-year loss. Hours earlier on Tuesday, the battered conglomerate rattled investors by failing to release its earnings on schedule, saying initially it was 'not ready' and then announcing later it needed more time to probe its Westinghouse nuclear business after internal reports uncovered potential problems. The figures eventually released were numbers that have yet to be approved by its auditor and Toshiba cautioned investors that a major revision was possible. Fully audited numbers are now not due till March 14 after the firm was granted a reprieve for its formal filing by Japanese regulators. "Finally now people are starting to recognize that internal control problems, the accounting issues and governance issues are very real and no longer abstract," said Zuhair Khan, an analyst at Jefferies in Tokyo. "They impact the viability of the company."

      Uhh, yeah.

      Over the years, Russia has committed to building something like 50 reactors. After Chernobyl, that was reduced to something like 25. They have grand plans for a closed fuel cycle using breeder/burners and reprocessing, and lots of other ideas. So far they've successfully built three. The rest remain hopelessly overdue or completely unfunded. They have decommed as many as they've built since 2000.

      China had big plans too, something between 50 and 100 reactors over a 25 to 45 year period. Then the 2008 Sichuan earthquake happened, and they learned that all the construction companies lied and cut corners practically everywhere. The famous school that collapsed only did so because the construction team couldn't be bothered to bend the end of the rebars in the vertical supports, which would have otherwise easily survived. This, needless to say, opened many people's eyes, and the plans have been scaled back to about 25 reactors.

      However, these plans are very much in doubt. CNNC based much of its economic arguments on buying up old western designs and then selling them, with Chinese financing, around the world. This did not happen, no one is interested in building nuclear and sales have been rather limited. As a result, the government has been somewhat more interested in renewables, which everyone is buying, and the country has since become the largest installer of wind and solar on the planet. They install more PV in the last five years than the entire planned nuclear buildout.

      Nuclear is dead. Siemens, Framitome, AECL, Westinghouse, Toshiba, B&W, BNFL, and on and on and on. The few remaining players are all on life support - GE looks very much like they'll end development with their current generation, Areva only remains alive due to repeated massive French taxpayer infusions, and CNNC's only prospects are local.

      You can pretend this isn't true, and many people reply to my messages talking about all these paper plans, but to anyone that's actually worked in the energy industry, the CAPEX > $7.50 is a death knell and everyone knows it.

      To escape long blackouts many times a year, Germany is planning to back up every gigawatt of wind and solar average capacity with another gigawatt of gas or coal. As it builds its intermittent fleet it will not be able to shut down existing fossil-fueled plants; they will remain in service, complete with staff, maintenance, and overhead expenses and the infrastructure of transmission lines, coal mines, and gas pipelines. And because the dispatchable nuclear generators that could have backed up wind and solar are being shuttered, additional coal and gas plants must be built to take their place—as we see happening now. Those coal and gas plants will emit large quantities of greenhouse gases even when idling in standby mode. ...
      Onshore wind is currently guaranteed at least €89.3 per megawatt-hour (MWh) for the first five years of operation, after which the tariff resets to about €49, a little above market rate. Offshore wind will get €150 per MWh for the first twelve years before a downward reset, with long extensions if the facility is located more than twelve miles from shore or where water is at least twenty meters deep. Photovoltaic solar gets roughly €120-180 per MWh, depending on the size of the rig, for a full twenty years. The tariffs are funded by a “renewable energy surcharge” added to electricity bills. A utility will pay a FIT of, say, €180 for a megawatt-hour of solar power; it will then sell that electricity on the wholesale market for perhaps €45 and charge the difference to the renewables surcharge.
      ...
      Even as the Energiewende staggers under exorbitant costs, renewables boosters tout its success in lowering electricity prices. The strange truth is, they’re not wrong. Tides of wind and solar electricity are forcing down prices on European wholesale markets and eroding the profits of conventional plants. French business leaders have complained about the competitive advantage their German rivals get because their renewable power is now cheaper than France’s nuclear electricity.
      Is renewable power winning a price war with Big Fossil and Nuclear? Not really. Germany’s feed-in tariffs disguise the fact that intermittent wind and solar power isn’t cheap at all—although it is often worthless. German grid operators are legally required to buy all the electricity wind turbines and solar panels produce, demand or no demand, at prices far above market rates. Having bought it, they then have to get rid of it, because an excess of electricity supply will crash the grid. So they dump it on the wholesale electricity market at bargain-basement rates. Midday solar dumps in sunny weather particularly eat into the profits of conventional plants by pushing down prices during times of elevated demand.
      These subsidies and market distortions do not yield a systemic lowering of electricity costs. They are simply transfers from German households that drastically overpay on surcharges to renewable generators—and to electricity-hogging industries that are exempt from surcharges but benefit from lower wholesale electricity prices when wind and solar flood the market.

    The West's largest coal power plant will be shut down decades before the end of it's useful life because it's "too expensive" to operate.

  30. AP1000 by MrKaos · · Score: 1

    It's not a very good product. That's why Toshiba is loosing money on this business.

    The suspended emergency cooling system makes the containment building a heat exchanger and a pressure vessel in case of an emergency. Not that that's a bad idea, however it's an untested design improvement. It's little wonder clients would be wary, with all the terrorism now a days.

    Its primary competitor is the EPR reactor whose containment building is double walled and resistant to military attacks, so it's a much tougher product in comparison.

    It's a shame that Toshiba's business is affected by this, but if it means no more AP1000s, that's probably not a thing to be too upset about, these are not the only flaws in the design and it doesn't make sense to complain about capitalism when it is working.

    EPRs were planned for US deployment last time I looked at the NRCs proposed deployments so perhaps EPR deployments will take over the AP1000s proposed there. The most appealing features I see is that EPR buildings are divided into four functional trains that can assume control of functions of the other buildings, and the control room is detached from the reactor, which mean better survivability for the operators, which means they have a better chance of getting things under control when there is an emergency.

    So it will be interesting to see how this all plays out.

    Nuclear is the cheapest even fully capitalized if run at capacity and efficiently, but nuclear has trouble scaling costs and generation to demand too; it basically has to be run at full capacity all the time to be effective.

    Which would mean we have a choice between "renewables" combined with very dirty coal or somewhat-cleaner-but-still-dirty methane; or going with an all nuclear strategy which would give us large quantities of zero-emissions energy.

    But that must, of course, be wrong. It violates the prime directive.

    True, both ways generate huge profits for the stock owners and CEO at the cost of the common people.

    But all new techs have bubbles and from the thousand of companies that show up, only a few will survive and grow, all others will go bust. Those that invest need to know how to choose and what to choose. Nuclear included

    it's the only power generation, at all, that's pre-funding cleanup..
    LOL!
    if you don't even know how much that cleanup will cost, how it is funding it!
    they must put some cleanup money now, because later may not be any money for that (company went bust) and the cleanup is REQUIRED due the time scale of the dangers, but you are crazy to think that money will be enough.
    Petrol, coal, gas, solar, water, etc may have a "half live" contamination of some years and about 100 years for the structures (maybe a little more for dams). Nuclear is thousand of years... some elements are millions of years. yes, pre-pay that because you will not rise from the dead to pay it later

    Rock do not protect you from leaks ->water sheet contamination->food chain.
    Also due the time scale, caves can collapse or give alternative open access and spread the radioactive elements
    Finally, malicious usage of the waste are also on the table, as again this is a ultimate weapon that can devastate a huge area.
    you have to protect this wastes for thousand of years... in containers that were designed to last 100 years (and as we see, are even lasting that long!)

    But if it so safe, go live near one of the waste storage.

    Recycling the nuclear waste may help, but it is also expensive and still do not solve all the problem, you just get more concentrate and dangerous nuclear waste that you still have to store. Maybe later there is a way to recycle the recycled waste, who knows!
    One of the problems of recycling the nuclear waste is that you need to move very dangerous waste all around the countries. Accident may happen and even worse, terrorist attacks

    2/3 is legal fees and other shit?! are you high?! there are requirements because this is dangerous, without then companies will sooner or later cut corners. but building a nuclear plan is huge investment due the all things needed, not because legal fees. just check how much it cost to build the protective casing in Chernobyl... there was no legal fees and it is now a full plant

    The only nuclear business that might make sense is recycling nuclear waste. Eventually, there will be desperate customers. The catch is that it may take a long time for the politicians to figure out there is no other way to get rid of nuclear waste.
