Avoiding Hurdles By "Going Small"; More Reasons for Smaller Nuclear Power Projects

ByRod Adams

…usly expressed their interest in seeing how systems like those proposed by Hyperion, NuScale, Toshiba and B&W are received by the NRC. Most of the rest indicated that they did not think it was a good idea to go small; from their point of view that did not get rid of the most important sources of uncertainty and complexity since the smaller projects have not yet started the process of obtaining an NRC license. In the hallway during breaks, I had a…

Don Hoffman is one of my heroes – a nuclear leader who recognizes threat from natural gas

ByRod Adams

…6,000 per kilowatt of capacity. This fits with a cost stated on a Toshiba ‘Hyperion’ web site about 2 years ago where they stated the cost for the Hyperion was about $10,000/kW and they were taking orders. That page was subsequently removed and I see they have withdrawn from applying for DOE funding for a demonstration. That is not promising. Can you say any more about the basis for your estimate of $8,000 to $16,000? When could we expect we to bu…

Thank Goodness I Do Not Live In the Northern Land Of Fruits And Nut Cases

…be able to be deployed and installed more quickly, but I am guessing that Hyperion is going to be in production for areas outside the US within the next 5 years. The barriers to entry that have been erected in the US to slow the development of innovative nuclear energy systems to something before a crawl do not exist everywhere. Of course, even Grizz’s vision of a “hot tub” size nuclear plant is going to be capable of producing as much as 75 MW o…

Nuclear Energy Is Cheap and Disruptive; Controlling the Initial Cost of Nuclear Power Plants is a Solvable Problem

ByRod Adams

…actors of the likes of Hyperion and NuScale. The projected cost of a 25MWe Hyperion reactor is $50M, last time I checked. This could potentially be financed by a community. And since they have a financial stake in it, there are local security advantages. That’s why I think that “localism” has further potential, beyond the locavore movement or other “buy local” ideas. We may see a “local energy” movement in this decade that embraces nuclear energy….

NRC Policy, Licensing, and Technical Issues for Small Modular Reactors (SMR)

ByRod Adams

…ctor space: (i) small LWRs (Nuscale, MPower), (ii) small LMRs (Toshiba 4S, Hyperion), and (iii) HTGR-type reactors (PBMR, Adam’s Atomic Engines) are all relatively mature — then there are are concepts like LFTR, and Hyperion‘s old hydride fuel design that are fascinating but a little further off. The regulatory scheme for a reactor is going to be highly dependent on what the reactor type is and what sort of safety issues it has. Small LWRs have t…

Wall Street Journal – Small Reactors Power Nuclear Industry

ByRod Adams

…uld fit an industry based on selling many smaller reactors like the B&W or Hyperion? There has been discussion on an updated approach to small reactor certification and licensing where do things now stand? Regulations seem to lag the technology instead of lead it. A one size fits all approach to regulation would continue to favor construction of large plants. trkdirect (Rasmus) There are additional advantages of smaller reactors that the article d…

Power cheaper than coal – thorium AND uranium make it possible

ByRod Adams

…This is why I like the LFTR. But it is also why I like to mention the old Hyperion design, pebble bed reactors and small light water reactors like MPower, NuScale and such. These reactors can supply cheap power safely. Most of them are inherently safe – meaning that if the operators walk away you will not get Electricity from them but you won’t get any damage either. It is impossible to have damage from them. I did not say this in my previous com…

Combine domestic coal with nuclear energy to make oil

ByRod Adams

…. It is a “third best” approach. As for reactors, a friend suggested using Hyperion‘s (Gen4) module. This is an excellent approach and perfectly suited for repurposing coal plants. One Hyperion module 70 MW(th) can fully service a sub-Bituminous coal plant that was operating at 200MW(e), or 17.5 kg/s of 10,130 Btu/lbm (sorry about the imperial units) coal feedstock into a product gas (multiply coal feed rate by HHV by cold gas efficiency to get pr…

McMurdo veterans’ cancers FAR more likely to be caused by cigarettes that by Nukey-poo

…this particular failed experiment, sounds like a worthy topic for a book. Hyperion – Uranium Hydride system would match this perfectly. EL Thanks for this. The Russians are certainly giving it a try. I travel a lot in the arctic, and runaway oil prices and tight supplies are a huge concern. Fuel subsidies consume 20% of the budget in Nunavut.

Importance of nuclear energy from perspective of developing world

ByGuest Author

…is needed for power production in a large number of places. A system like Hyperion‘s original design – a “nuclear battery” – would work in areas that have very weak systems, transportation, distribution and political. It would be small enough and simple enough to be a reasonable investment opportunity for a co-op. Getting LFTR’s going that are simple enough to put in these remote areas would really get me pumped. With the presence of U232 protect…

Professional Anti-Nuclear Analysts Deny the Existence of a Nuclear Revival

ByRod Adams

…rhaps several hundred years, though limited scale ones, like the LFTR, the Hyperion, and the 4S will be common well before then. I doubt that the general public will fight against a nuclear powered world. The previous fight was caused by those who grew up in the era of atomic testing and the Cuban Missile Crisis coming of age and fallaciously connecting atomic bombs with nuclear power (kind of like saying “Napalm is evil and must be banned. Napalm…

Mark Cooper is wrong about SMRs and nuclear energy

ByRod Adams

…e same core for a number of years and then swapping it out. I really liked Hyperion‘s initial design. The simplicity was great. Your design has the advantage of using Nitrogen rather than helium. Helium was the killer for the pebble bed designs in South Africa. If the US Navy can train high school graduates to run Light Water Reactors, I am sure that it is possible to train high school graduates to run a pebble bed reactor. Honestly, this is less…
