  • 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…

  • 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…

  • History and promise of high temperature gas cooled reactors

    By: Diarmuid Foley A small modular nuclear reactor to replace coal plants could be on the market within 5 years. In 2014, the Generation IV international forum[1] confirmed the Very High Temperature Reactor (VHTR) as one of 6 promising reactor technologies that should be pursued in order to develop advanced reactors suitable for deployment in…

  • Will China convert existing coal plants to nuclear using HTR-PM reactors?

    It would be a huge benefit to the earth’s atmosphere if China, India, Brazil and the US could reduce direct coal burning while still making use of much of the capital that they have invested in building coal fired power plants. It would make an even larger difference in reducing air pollution in the areas…

  • 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,…

  • Atomic Show #238 – StarCore Nuclear co-founders

    StarCore Nuclear is a Canadian company whose co-founders, David Dabney and David Poole, are experienced engineers and businessmen. They have spent most of the past six years developing a technology and a business model aimed at providing reliable, emission-free electrical power and heat to remote locations. The basis of their technology is a high-temperature helium…

  • 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…
