Classic ORNL MSRE Film

This film was produced in 1969 by Oak Ridge National Laboratory for the United States Atomic Energy Commission to inform the public regarding the history, technology, and milestones of the Molten Salt Reactor Experiment (MSRE). Oak Ridge National Laboratory's Molten Salt Reactor Experiment was designed to assess the viability of liquid fuel reactor technologies for use in commercial power generation. It operated from January 1965 through December 1969, logging more than 13,000 hours at full power during its four-year run. The MSRE was designated a nuclear historic landmark in 1994. Thanks to Y-12 for the collection, preservation and digitization of ...

Thorium Remix 2016

Gordon McDowell has completed and released his two-hour documentary "Thorium Remix 2016" and it is a fantastic introduction to the technology of thorium molten-salt reactors and the LFTR design in particular. Flibe Energy and other MSR developers are mentioned and described. Please enjoy and consider participating in Gordon's Patreon program!

Chloride Reactor Research Funded by DOE

The Department of Energy has issued two awards on January 15 under their Funding Opportunity Announcement of July 31, 2015. Energy Department Announces New Investments in Advanced Nuclear Power Reactors to Help Meet America’s Carbon Emission Reduction Goal In what took many of us by great surprise and delight, one of the announced winners was a molten-salt reactor concept. This marks the first time that the Department of Energy has committed any funding to an actual molten-salt reactor. Southern Company Services---partnering with TerraPower, Electric Power Research Institute, Vanderbilt University, and Oak Ridge National Laboratory to ...

EPRI Report on LFTR Published

For most of the past year, I have been working steadily on inputs to this report, now published by the Electric Power Research Institute. EPRI: Program on Technology Innovation: Technology Assessment of a Molten Salt Reactor Design -- The Liquid Fluoride Thorium Reactor (LFTR) It contains the most comprehensive description of the liquid-fluoride thorium reactor (LFTR) concept to date, along with the results of an exercise in possible effects from various failures or operational anomalies. Thanks go out to EPRI and Southern Company for providing the funding for the study, and to Teledyne Brown Engineering for the administration of the research ...

Medical Isotopes from the LFTR

Radiopharmaceuticals, also called medical isotopes, are specialized forms of medicine that help to diagnose and treat many challenging medical conditions including cancer. Their central advantage over other pharmaceuticals is that they emit radiation in the form of a photon of light that can be used to diagnose or identify specific conditions, or a charged particle of matter that can destroy diseased cells. Targeted alpha therapy is an example of a technology that is used to kill dispersed cancers such as leukemia and lymphoma. A radioisotope that undergoes alpha decay is chemically bonded to an antibody and injected into the body. The antibody ...

1965 MSRE editorial from Oak Ridge

Several days after the successful start of the Molten-Salt Reactor Experiment, the local paper, the "Oak Ridger", published this editorial: THE OAK RIDGER FRIDAY, JUNE 4, 1965, page 4 Editorial: Significant Step To 'Burning The Rocks' Many important stews lead up to the "going critical" of a new reactor. For instance, in the case of Oak Ridge National Laboratory's Molten Salt Reactor Experiment, one of the key moments was in January when the pumps were turned on and the molten salts of the system were first circulated. Perhaps the most important phase of any reactor's development is when the idea is first conceived. For, as has been ...

MSRE 50th anniversary

For many nuclear engineers, the moment a new reactor first achieves criticality is considered the "birth" of their creation, the moment it "comes alive". Criticality is special, because it means that the reactor is generating new neutrons at precisely the rate at which they are consumed in fission. Unlike a rocket launch, or a ship sliding into the harbor from its construction dock, the moment of criticality has no outward excitement attached to it. Were one to be looking at the reactor at that moment, it would be unlikely that one would even discern that criticality had been achieved, because usually the first criticality takes place at an ...

TU Delft Symposium on Thorium MSR

At the invitation of Dr. Jan-Leen Kloosterman of the Delft University of Technology (Technische Universiteit Delft, TU Delft) I attended a symposium on thorium in molten-salt reactors held on April 17, 2015. Other participants included David LeBlanc of Terrestrial Energy and Leslie Dewan of Transatomic Power. My objective was to make the case that the thorium fuel cycle, integrated with the molten-salt reactor, represented the best path forward for humanity's energy future. I began with a review of the dates of Glenn Seaborg's pioneering work on thorium as well as the early technological achievements at Oak Ridge National Laboratory. I ...
