       The Max Planck Institute of Plasma Physics is a German physics institute dedicated to the exploration of plasma physics for potential use in the creation of commercial fusion power reactors. It is an institute of the Max Planck Society and has two sites; one in Garching near Munich and one in Greifswald. It is host to several large experimental devices including the experimental tokamak ASDEX Upgrade, the experimental stellarator Wendelstein 7-AS, the experimental stellarator Wendelstein 7-X, and a tandem accelerator.
       It is designed to advance stellarator technology and evaluate the major components of a possible future fusion power reactor. As of 2015, it was the biggest stellarator in the world. The researchers are hoping to be able to demonstrate thirty minutes of continuous operations, a crucial milestone on the way to commercial fusion power. Earlier tests of the Wendelstein 7-X resulted in world records for highest temperature, greatest plasma density, longest pulses and fusion products.
       The term “fusion product” is the mathematical product of the temperature of a plasma, the density of the plasma and the energy confinement times. This product is a measure of how close a device is to achieving a nuclear fusion reaction. 
       A stellarator is a device that is designed to confine hot plasma with magnetic fields for the purpose of creating a controlled nuclear fusion reaction. In the toroidal fusion machines called tokamaks, instabilities develop in the donut shaped confinement chamber. The stellarator was designed to eliminate such instabilities by creating magnetic fields that force the particles traveling around the circular containment vessel to travel in twisted paths. The “magnetic cage” of the Wendelstein 7-X is created by a ring of fifty superconducting coils that are each about eleven and a half feet tall. Their exact shapes are the result of extensive optimization calculations.
       Since the previous round of tests, the Wendelstein 7-X has had the walls of its containment vessel covered in graphite tiles. This will permit higher temperatures and longer plasma discharges. Plasmas of up to twenty-six seconds are now being produced. The plasma can be fed with a heating energy of seventy-five megajoules which is almost eighteen times the heating energy that was possible before the new graphite wall tiles were installed.
      The latest fusion product for the Wendelstein 7-X stellarator encourages the researchers to believe that they are on the right track. Dr. Andreas Dinklage, the first author of the report on the new experiments said, “Thus, already during the first experimentation phase important aspects of the optimization could be verified. More exact and systematic evaluation will ensue in further experiments at much higher heating power and higher plasma pressure.”
      Since the end of 2017, the Wendelstein 7-X has received additional upgrades. New measuring equipment and heating systems have been added. Plasma experiments will begin again in July of this year. Major extensions are scheduled for the fall of 2018. The graphite wall tiles will be replaced by carbon-reinforced carbon components that are water-cooled.
       The Wendelstein 7-X is not designed to actually produce more energy than it consumes. Part of the reason for the new experiments is to prove that the stellarator approach can yield fusion products equal to or better than the tokamak approach to controlled nuclear fusion.

       The U.S. House Energy and Commerce Subcommittee on Energy approved four bills on Thursday for release to the House Energy and Commerce Committee. The chairman of the subcommittee said that these four bills “would take important steps to address key challenges facing the U.S. nuclear energy industry today.” He went on to say, “Throughout this Congress, we have repeatedly heard about the immense challenges facing all parts of our nation’s nuclear industry. While individual states have taken steps to preserve specific nuclear power plants, the underlying intellectual and industrial nuclear infrastructure is at risk of further atrophy in the absence of a coherent and defined policy from the federal government.”
       The Advancing U.S. Civil Nuclear Competitiveness and Jobs Act is aimed at improving the competitiveness of the U.S. nuclear industry in the global marketplace. The bill instructs the Secretary of Energy to analyze how regulations, policies and legal requirements affect the ability U.S. nuclear companies to compete internationally. The Act also requires the Secretary of Energy to report on possible ways to improve that ability. My concern is that the Secretary of Energy may conclude that proper regulation of nuclear power plants is less important that making the plants more competitive in the energy market.

       The Advanced Nuclear Fuel Availability Act provides for the establishment of a new program inside the Department of Energy. This program would be charged with task of making “high-assay low enriched uranium” more available to researchers who are working on advanced nuclear technology development. This bill would also create public-private partnerships to help overcome the regulatory and market barriers that prevent nuclear engineers and scientists from obtaining the advance nuclear fuel they need for their research. This is obviously a good idea as long as the research balances the need for safe fuels with the need for cheap and efficient fuels.
       The Nuclear Utilization of Keynote Energy is dedicated to enhancing the ability of the Nuclear Regulatory Commission to recover fees. The bill would make the NRC fee recovery more predictable, transparent and efficient. I am definitely in favor of this idea. The nuclear industry must foot the bill for proper nuclear power plant regulation.
        The fourth bill does not have a long name. It is just referred to as H.R. 6141. The purpose of this bill is to direct the Secretary of Energy to research and write a report on a pilot program whose purpose is to select a site, carry out construction and then operate micro-reactors at critical national security locations and other sites. This bill would help ensure that facilities connected to national security would have a local and reliable source of energy if the national electrical grid collapsed.
        The chairman of the House Energy and Commerce Committee said, ““Each of these bills can help reinvigorate different components of our nuclear ecosystem In doing so, the legislation will facilitate innovation and competition, which provides the dual benefit of both being good for consumers while protecting our national security interests.”
