  • Bechtel will “pursue” accelerated mPower development

    I’ve relearned a valuable lesson — read press releases and other PR material closely, paying special attention to wiggle words. On Friday, March 4, Bechtel issued a press release titled Bechtel, BWXT to Pursue Acceleration of Small Modular Nuclear Reactor Project. In my excitement, I missed the key word in the headline and in the…

  • Bechtel and BWXT have announced an acceleration of Generation mPower

    Note: For an update on this topic see subsequent post titled Bechtel will “pursue” acceleration of mPower project. On March 4, 2016, in a press release issued from Reston, VA, Bechtel and BWX Technologies (BWXT) announced that they would be accelerating their Generation mPower small modular reactor project. Bechtel will take over the project lead…

  • DOE and UAMPS sign agreement for siting at INL

    At the 12th annual Platts Nuclear Energy Conference, John Kotek, the Acting Assistant Secretary of Energy for Nuclear Energy just made a major announcement. Yesterday, February 17, 2016 Rick Provencher and Doug Hunter signed an agreement between the U.S. Department of Energy and UAMPS (Utah Associated Municipal Power Systems). It provides UAMPS with a use…

  • U-Battery – Micronuclear power with intriguing business model

    U-Battery was one of the more intriguing presenters at the Advanced Reactor Technical Summit (ARTSIII) held at the Oak Ridge National Laboratory last week. Even though this was a technical summit, the segments of the presentation that captured my attention were the business model and the funding source. However, certain technical choices are vital to…

  • Atomic Show #248 – Dr. Pete Pappano, VP Fuel Production X-Energy

    On Thursday, November 19, 2015, I interviewed Dr. Pete Pappano, vice president of fuel development for X-Energy. As described in X-Energy introduced its company and first product to Virginia chapter of ANS, X-Energy is a start-up company based in Maryland that is developing a modular high temperature gas cooled reactor. Each module will produce 50…

  • Treasure trove of documents about the ML-1, the US Army’s trailer-mounted, nitrogen-cooled, atomic fission-heated generator

    I recently published an article featuring a video from the Army Nuclear Power Program that focused on the Army’s mobile, low power closed cycle nitrogen cooled nuclear reactor designated the ML-1. The article generated a good discussion that indicated a strong desire for more information about the program. My initial searches didn’t turn up a…

  • 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,…

  • GE-Hitachi and DTE announce additional ESBWR detailed design work

    GE-Hitachi issued a press release on October 5 indicating that they will be working with DTE to determine the resource requirements and schedule for performing the detailed design work necessary to build an ESBWR (Economic Simplified Boiling Water Reactor) as Fermi Unit 3. Though DTE has not announced a decision to build the facility, it…

  • Atomic Show #242 – Moltex Energy – Ian Scott and John Durham

    Moltex Energy has developed a unique conceptual design for a molten salt reactor called the Stable Salt Reactor. In this design, the fuel salt is loaded into tubes that resemble the standard cladding tubes into which solid pellets are loaded in a conventional water cooled reactor. The tubes are arranged into assemblies that resemble the…

  • Sad-ending story of EBR-II told by three of its pioneers

    During the period between 1961 and 1994, an extraordinary machine called the Experimental Breeder Reactor 2 (EBR-II) was created and operated in the high desert of Idaho by a team of dedicated, determined, and distinguished people. In 1986, that machine demonstrated that it could protect itself in the event of a complete loss of flow…

  • Integrating six decades of learning about fast reactors

    I learned some important new concepts yesterday from two of the leaders of the Integral Fast Reactor (IFR) project – John Sackett and Yoon Chang. Among other things, they informed me — as a member of a group of about 35 other attendees at a workshop titled Sustainable Nuclear Energy for the Future: Improving Safety,…
