Observations from the US Nuclear Industry Council’s 10th annual Advanced Reactor Summit
ByRod Adams July 10, 2023February 17, 2025

…attending organizations from earlier years are mere memories. TransAtomic, Hyperion (later renamed as Gen IV), B&W mPower (my former employer) and Westinghouse SMR are companies or projects that did not gain sufficient traction to persist in the extreme endurance contest of SMR and advanced reactor development. In contrast, some of the earliest attendees have grown considerably and passed through important milestones. These are not just technical…

Don Hoffman is one of my heroes – a nuclear leader who recognizes threat from natural gas
ByRod Adams August 31, 2012July 4, 2020

…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 That page was subsequently removed and I see they have withdrawn from applying for DOE funding for a demonstration.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
ByRod Adams June 4, 2010July 17, 2020

…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 February 6, 2010December 15, 2022

…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 April 15, 2010July 19, 2020

…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 February 18, 2010December 15, 2022

…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…

McMurdo veterans’ cancers FAR more likely to be caused by cigarettes that by Nukey-poo
ByRod Adams March 7, 2011July 6, 2020

…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. DV82XL We reap what we sow. Governments in the US, the UK, and Canada (in cases that I know of) are facin…

Combine domestic coal with nuclear energy to make oil
ByRod Adams March 2, 2012July 4, 2020

…. 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…

Power cheaper than coal – thorium AND uranium make it possible
ByRod Adams December 12, 2012July 14, 2020

…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…

Importance of nuclear energy from perspective of developing world
ByGuest Author July 15, 2013July 4, 2020

…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…

…lity to do that. It would also be possible to use phase change materials(e.g. salt water eutectic) to give a freezer the abillity to soak up quite a lot of intermittent electricity. Bill Woods Hyperion‘s reactors are $25â€“30 million for 25 MWe. That’s about 1 $/W, not 2. The catch is that they only last 5â€“10 years, rather than a LWR’s 40â€“60 years….
