Small Nuclear Power Plants

  • X-Energy introduced its company and first product to Virginia chapter of ANS

    On Tuesday, October 27, three leaders from X-Energy spoke to the Virginia ANS chapter about their company and the Xe-100, the high temperature, pebble bed gas reactor power system that they are designing. During the presentation, meeting attendees learned that X-Energy is an early phase start-up with a total staff of a few dozen people,…

  • SMRs – lots of noise but DOE budget that’s 1% of annual wind tax credit

    I’ve been spending some time watching, rewatching and clipping interesting excerpts from the Senate Appropriations Energy and Water subcommittee hearings on the FY2016 Department of Energy budget. It’s not everyone’s idea of entertainment, but it’s fascinating to me to watch publicly accessible discussions about how our government makes decisions, sets priorities and spends the money…

  • Tour of NuScale control room and test facility

    Disclosure: I have a small contract to provide NuScale with advice and energy market information. That work represents less than 5% of my income for 2014. On October 20, 2014, I had the opportunity to visit NuScale’s facilities in Corvallis, OR. Though the company now has offices in three cities, Corvallis, the home of Oregon…

  • UAMPS stepping forward to serve customers

    The established nuclear energy industry has taken a wait-and-see approach to the idea of developing and deploying smaller, simpler fission power stations that can take advantage of the economy of series production. The industry’s trade organization, the Nuclear Energy Institute, has expressed cautious optimism and has engaged in a moderate effort to identify regulatory obstacles…

  • Prospective customers lining up at NuScale

    A few days ago, Dan Yurman at Neutron Bytes published a blog post that is now titled Flash: NuScale executive says firm may build SMRs at Idaho lab. It was a follow-up to an earlier post in which Dan speculated about the Idaho National Lab’s potential as a good site for a new nuclear power…

  • The Canadians are coming

    Hugh MacDiarmid, the Chairman of the Board for Terrestrial Energy, Inc., gave a talk to the Economic Club of Canada on September 24, 2014. That talk included a brief description of TEI’s integral molten salt reactor technology, but most of the talk was visionary in nature and aimed at exciting his Canadian audience about the…

  • HTR-PM – Nuclear-heated gas producing superheated steam

    The first HTR-PM (High Temperature Reactor – Pebble Module), one of the more intriguing nuclear plant designs, is currently under construction on the coast of the Shidao Bay near Weihai, China. This system uses evolutionary engineering design principles that give it a high probability of success, assuming that the developers and financial supporters maintain their…

  • Fission is an elegant way to heat a gas

    What if it was possible to combine the low capital cost, reliability, and responsive operations of simple cycle combustion gas turbines with the low fuel cost and zero-emission capability of an actinide (uranium, thorium, or plutonium) fuel source? Machines like that could disrupt a few business models while giving the world’s economy a powerful new…

  • SMRs – Why Not Now? Then When?

    I have shamelessly borrowed the title of one of the talks given during the first day of the Nuclear Energy Insider 4th Annual Small Modular Reactor (SMR) Conference as being representative of both the rest of the agenda and the conversations that I had in the hallways during the breaks. For the past five years,…

  • SUNY Maritime Student Advocates Commercial Nuclear Ship Propulsion

    Stimulated by early atomic optimism, naval successes and Eisenhower’s Atoms for Peace initiative, four nations built ocean going ships with nuclear propulsion plants. The US built the NS Savannah, Germany built the Otto Hahn, Japan built the Mutsu, and Russia built a series of nuclear powered icebreakers. For reasons that are beyond the scope of…
