Back to the Future: Advanced Nuclear Energy and the Battle Against Climate Change

January 19, 2015 by Josh Freed

Advanced Nuclear and Climate Change

What, after a 30-year drought, is drawing smart young people back to the nuclear industry? The answer is climate change. Nuclear energy currently provides about 20 percent of the electric power in the United States, and it does so without emitting any greenhouse gases.[read more]

ThorCon: Demonstrated Molten Salt Tech Packaged With Modern Construction Techniques

January 9, 2015 by Rod Adams

ThorCon is a packaged nuclear power plant concept from Martingale, Inc. that is designed to wring capital costs out of nuclear plant construction. The company visionaries have recognized that the biggest hurdles to building new actinide-fueled reactors are the initial capital investment.[read more]

New Nuclear Technology and Nuclear Proliferation.

May 23, 2012 by Charles Barton

During World War II the United States spent a large amount of money on developing nuclear technology. Much of that investment went into industrial systems designed to separate U-235 from U-238, or to transform U-238 into Pu-239. Here such systems were built in Oak Ridge, Tennessee, My childhood hometown. The Uranium separation...[read more]

Why Is Renewable Energy So Expensive, While Molten Salt Reactors will be So Cheap?

June 9, 2011 by Charles Barton

Sometimes dull stories have interesting endings. An examination of materials inputs for wind generation systems and Solar PV generation is offered and then compaired to with material inputs for the Advanced High Temperature Reactor. This study reveals that the AHTR, a near relative of the Molten Salt Reactor, offers material input advantages. MSRs can potentially offer the same material input advantages over renewables, and thus may generate electricity at very competitive costs.[read more]

Efficient Cars and Nuclear Power Efficiency

June 2, 2011 by Charles Barton

I must confess that I am of two different minds on the topic of efficiency. On one hand I am critical of the notion that efficiency can replace post carbon energy generation, yet I also have devoted a considerable effort to increasing the efficiency of the process of building nuclear power plants. In addition, I am conducting a...[read more]

Future Ship Propulsion

May 23, 2011 by Charles Barton

Ship propulsion poses one of the more troubling post-carbon problems. It should be noted that ships were once powered by wind energy, sometimes supplemented by oars rowed by slaves. This form of propulsion was very unsatisfactory and renewable energy was replaced by fossil fuel derived energy during the 19th century. There were a...[read more]

The Molten Salt Reactor Family: One Fluid Reactors

May 2, 2011 by Charles Barton

One of the fundamental ways to classify Molten Salt Reactors is the concept of one and two fluid reactors. A one fluid reactor is homogeneous, or as David LeBlanc explains, both the fertile and fissile material is within the same carrier salt.It might be added that moderators and fission products can also be carried in the single fluid...[read more]

The Molten Salt Reactor Family: Fuel

April 25, 2011 by Charles Barton

I intend to offer a series of posts designed to explain the sometimes bewildering complexity of Molten Salt Reactor Technology. This first post explains two nuclear fuel breeding cycles.Rather than offering a single potential reactor design, the Molten Salt Reactor (MSR) idea offers a large number of design options, each of which would...[read more]

Kirk Sorensen On Why Molten Salt Thorium Reactors Didn't Succeed the First Time?

January 2, 2011 by Rod Adams

Kirk Sorensen is the founder of Flibe Energy. He has been prospecting in libraries for years to learn more about a path not taken (yet). He is convinced that the way forward for energy in the United States and around the world is the molten salt thorium reactor that can produce an almost unlimited amount of power for millennia.The...[read more]

The LFTR in the American Scientist

June 12, 2010 by Charles Barton

The LFTR story has now been told for the July-August Issue of the American Scientist by Robert Hargraves and Ralph Moir. The American Scientist account tracks closely with the views offered by Nuclear Green. Of course, the LFTR community is collegiate, and both Hargraves and Moir have contributed important ideas to us. The Hargraves-...[read more]

Understanding Molten Salt Reactors: 1. How are MSRs Different from LFTRs?

June 2, 2010 by Charles Barton

The name Molten Salt Reactor (MSR) is more inclusive than the name Liquid Fluoride Thorium Reactor (LFTR). The LFTR is a type of Molten Salt Reactor that features the use fluoride salts and a thorium fuel cycle. Strictly speaking a LFTR need not be designed to produce fuel in a breeding range, but breeding is an important justification...[read more]
