Small Nuclear Power Plants

  • Atomic Show #277 – Simon Wakter, pro-nuclear engineer in an ambivalent country

    Simon Wakter is a strongly pro-nuclear engineer in a country that passed a referendum officially phasing out nuclear energy since several years before he was born. He has to round up to be called a thirty-something. Simon works in the nuclear energy branch of AFRY, a well-established 17,000 employee, all-of-the-above. engineering company that recently adopted…

  • Atomic Show #276 – HolosGen Claudio Filippone and Chip Martin

    HolosGen has attacked the nuclear power plant cost and schedule challenge from the opposite direction chosen by many nuclear reactor developers. Claiming to be agnostic about the reactor specifics – as long as it produces reliable heat in a small-enough configuration – HolosGen founder Claudio Filippone decided to focus on radical improvements to the “balance…

  • What exploded in Russia on Aug 8? My estimate is a (chemical) booster rocket for a nuclear powered cruise missile.

    A cruise missile with a nuclear reactor heated turbofan engine and a liquid fueled booster rocket is the most likely description of the Russian developmental weapons system that exploded while being tested on August 8. It’s likely that the explosion occurred during maintenance or fueling operations on a barge floating off shore and not during…

  • Project Pele – Part II. Enabling technologies

    Building mobile nuclear power plants will be a challenge, but successfully meeting the challenges could alter the future trajectory of the energy and fuels supply industry. That is one of the largest and most consequential sectors of our modern, mobile, industrialized economy. There are no guarantees, but compared to many research and development projects, Project…

  • ML-1 Mobile Power System: Reactor in a Box

    This is an August 2022 update of an article first published in November 1996 and updated in February 2019. The first update was stimulated by discussions associated with DOD’s issuance of an RFI for mobile, modest power output atomic power systems. That RFI resulted in Project Pele, which has now selected BWXT to build a…

  • Fission heated gas turbines address MIT Future of Nuclear challenges. Easier, straighter, less costly path

    Addressing Recommendations of MIT Future of Nuclear Energy In a Carbon Constrained World The Massachusetts Institute of Technology (MIT) is a world renowned institution that has produced thousands of highly educated engineers and scientists. It is generously supported by foundations, corporations and governments. In 2003, the MIT Energy Initiative, began publishing a series of reports…

  • NuScale announces a major step in the NRC’s review of its passively safe SMR

    NuScale, a leader in the increasingly competitive field of advanced nuclear reactor design, has announced that the U.S. Nuclear Regulatory Commission (NRC) reviewers issued a document that formally agrees that their design does not require any electrical power to achieve safe shutdown. It’s difficult to explain the importance of that regulatory position. People with experience…

  • Urenco, Bruce Power Sign MOU To Develop U-Battery for Canada

    Urenco, Bruce Power and AMEC NSS Limited recently announced that they had signed an MOU to cooperate in the design, licensing and development of Urenco’s U-Battery micro nuclear system for the Canadian electricity and heat market. The U-Battery contains a 10 MWth nuclear heat source that can be configured to produce either 4 MWe plus…

  • Clean and Doable Liquid Fission (LF) Energy Roadmap for Powering Our World

    By: Robert Hargraves and Chris Uhlik Introduction This essay responds to an article by Stanford Professor Mark Z. Jacobson et al, 
100% Clean and Renewable Wind, Water, and Sunlight (WWS) All-Sector Energy Roadmaps for 139 Countries of the World. Their controversial WWS roadmap has several interesting features and benefits. Coal, natural gas, and petroleum energy…

  • Bechtel And BWXT Quietly Terminate mPower Reactor Project

    Generation mPower, one of the early leaders in the development of small modular reactors (SMR), has decided to fully terminate its partnership and put the design material that was developed onto a corporate shelf. Though this isn’t specifically good nuclear news, it is an indication that nuclear energy development has many hurdles that it shares…
