Setback For Small Nuclear Reactors: B&W Cuts mPower Funding

mdsolar (1045926) writes with news that funding for the mPower, a Small Modular [Nuclear] Reactor, has been cut due to the inability to find investors interested in building a prototype. From the article: "The pullback represents a major blow to the development of SMRs, which have been hailed as the next step forward for the nuclear power industry. ... All told, B&W, the DOE, and partners have spent around $400 million on the mPower program. Another $600 million was needed just to get the technology ready for application to the Nuclear Regulatory Commission for licensing. ... B&W plans to continue low-level R&D on the mPower technology with a view to commercial deployment in the mid-2020s, said CEO James Ferland. But without a major shift in the business environment and in investor perceptions of the risks and rewards associated with nuclear power, that seems fanciful."

      Maybe the modular plant will actually be cheaper once your start producing them in volume, given a streamlined licensing path the the SMR.

      If I had an extra 10 billion USD, I would invest heavily in SMRs -- mPower, not a dime. I would bet on LFTR and maybe other fission techs. For example, this reactor design looks like a nice candidate for an intermediate complexity solution -- still a big downside in term of fuel burnup, but might be worth the investment too.

      Nothing for fusion though, I don't expect to live long enough to see it pay it. I see SMR as a natural outcome of better tech, not a tweak of a pressurized light water reactor.

      The EBR II was demonstrated to be passively safe. That is they performed tests that demonstrated what would happen in a full power loss or circulatory system failure. In all cases the reactor shut down the nuclear reaction safely and without damaging the core. Because these reactors aren't using water as the coolant they can operate at near atmospheric pressures even at very high temperatures. That means that you don't have to worry about the reactor vessel developing a high pressure leak and dumping radioactive crap into the environment. As the temperature climbs from lack of cooling the pressure doesn't rise like it would in a water cooled system. Also the core is designed such that as the temperature rises the fuel cladding expands and shuts down the reaction by increasing the separation between the fuel components.

      The only real hazard seems to be with sodium coolant designs where special care has to be taken to not let the sodium come into contact with oxygen or water because that would cause fires.

Everything is built on-site. There is limited standardization. By making the plants in the 100 MW range, you can build the components in an assembly line and put them on a truck or train.

      Ok, I read the journal article and a couple of the referenced papers. Thank-you, I found it interesting. Here's my take, as an engineer... And please, read through to the end because my conclusion is slightly different, partially supports your premise, and is relevant to the discussion at large.

      The authors of the study do show that it is theoretically possible to meet capacity 99.9% of the time using only renewables. They make certain assumptions about improvements in technology driving down costs through 2030, which are all reasonable. Unfortunately, in order to make the argument that costs are comparable to today's electricity expenses, they include externalized costs (more on this later). Since nationwide medical expenses and environmental expenses incurred due to energy production are not born by the utilities, the concept becomes non-viable economically. It then becomes a policy question at the national level (since the study area covers multiple states, making policy at the state level would not be effective)

      In addition, the system requirements to meet the author's proposal require keeping 28 GW of fossil fuel generating capacity for the 0.1% of the time that renewables with storage cannot be expected to supply demand. Even if one assumes that existing plants are used for this purpose, so no new plants are required, the maintenance costs keeping a plant operational for use .1% of the time are too high to be economically feasible. For a good fraction of the year, these plants would remain cold. However, most fossil fuel plants take time to bring online and heat up; so, for several months of the year the plants would have to remain running in a hot idle state, burning fuel, so they could come online when demand peaks and wind power is at a minimum. This does not appear to be included in the author's calculations.

      The article avoids nuclear entirely, which is not surprising. It does appear in one table where the authors add the externalized costs to PJM's current production matrix. In this table, the authors show that both the operating costs and the externalized costs for nuclear, as of 2010, are similar to those of hydro and wind. These resources (nuclear, hydro, and wind) are shown to be substantially below current costs for fossil fuels with or without externalized costs. The methodology of the article, where wind supplies the bulk of power generation, does not work with nuclear in the mix as nuclear plants are only cost effective if they are making base load power continuously. The high costs for renewable generation found in the article were reached by including substantial energy storage and by the need to have in excess of 230% peak demand in total nameplate capacity for the renewable generators. By restructuring the mix with a smaller percentage of renewables, the author's findings do suggest that we could economically meet our energy demands using a mix of nuclear power and renewables.

Any nuclear material leaving a high security facility on a train or an arm-guard-cash-truck or in any way is a safety issue.

    But there is a need for mobile small scale nuclear power, the most important example being military submarines, which simply cannot function on diesel, as they have to get oxygen from the air, and their tactical situation may require deep underground stays for weeks at a time. Also nuclear fuel needs recharging only every few years, as opposed to every other week with diesel. That's a very important military consideration, as half of all military issues relate to logistics, and supply of materials to the battlefronts. Only nuclear power makes sense for a submarine, and it has to be mobile and small scale. The logistics issue of bi-weekly diesel fuel deliveries also requires carriers to be nuclear powered, needing only a biannual refueling. Do we really need submarines and carriers? Yes.

A major hospital should have reserve batteries to last at least 20 minutes, then reserve diesel to last two weeks (when electricity goes out natural gas may still be available indefinitely, so generators based on that should be run before diesel stores are touched, (the same generator should be able to run both diesel and natural gas), but if both electric and natural gas is lost then you need), with ability to request the military to deliver one of these or a couple of these air-cooled airplane-engine units in a high security, heavy military defended way, operated by military personnel until power connections to regular power plants can be reestablished, or if not, indefinitely guarded. The air cooled part is what would take up 95% of space, the reactor itself being very small, as availability of water cooling cannot be guaranteed, the hospital may be lucky to sustain its water supply from local wells, if the water-pipeline/sewer infrastructure also fails. Groundwater wells should be mandatory for such hospitals, and empty spaces should be reserved within a mile range of hospitals to acco

    This is nonsense. Treating 10k children by giving them prophylactic iodine and periodically checking thyroids is not treating them for cancer. Several hundred children in the surrounding area did get thyroid cancer based on the result I just re-read. Almost all of them responded to treatment (they did not die).

    Hundreds did not die daily in the cleanup. A million people did not die in the immediate aftermath. The amount of radioactive material released was large; the "liquidators" received an average dose of 16.5 REM. That's high but not at all lethal. It carries an increased cancer risk of a few percent at most. The city was evacuated but people continued to work in the plant for a decade afterwards, with at least two of the reactors remaining online generating power.

    It would be easier if we followed the same principle as captains of ships used to have.

If he makes sure that people who know what they're doing are in charge of the right things, and he doesn't try to cut any corners, this won't be an overly onerous requirement.

  83. The Insanity of the Anti-Nuclear Regulators. by lucien86 · · Score: 1

    Reading the article, its just the same here in the UK. It is almost impossible to do anything new in nuclear research or technology and stupidly ridiculously expensive. The problem is insane Nuclear over-Regulation. The only solution is obvious, we need to destroy the current nuclear regulators (both national and UN level) and replace them with a sane sensible workable system.

    A few Facts -
    - Coal is roughly 1000x more dangerous than nuclear (per unit generated) but is about 100x less regulated.
    - Since WWII coal and other fossil fuels have killed something like 50 to 80 million people through air pollution alone.
    - Even taking the absolute worst case estimates and including Chernobyl, Fukushima, plus Hiroshima and Nagasaki, nuclear power in total has killed something like 250,000 to 500,000 people worldwide.
    - Since the mid 1970's the global anti-nuclear 'green' campaign has effectively forced the world back towards fossil fuels and this has indirectly killed something like an extra 5 to 8 million people worldwide. In this the anti-nuclear lobby and the (anti) nuclear regulators are equally culpable.

    - So far Anti-nuclear campaigners have actually killed something like 10 times the number of people as nuclear weapons.
    - So far Anti-nuclear campaigners have actually killed something like 10,000 times the number of people as nuclear power.
    Conclusion : In general Anti-nuclear campaigners (& the nuclear regulators) are far more dangerous than nuclear power.

    Yet which is it the simple people fear? nuclear power. (The reasons why are another article but the anti-nuclear campaign has always relied on the use of black propaganda - panic fear lies and hysteria.)
