       I have blogged recently about the left-over radioactive pollution from the Cold War and the development of nuclear weapons. There are a number of famous sites where the weapons work was carried out that are horribly polluted to this day such as the Hanford Nuclear Reservation in Washington State. But in addition to the actual sites where the work was done, there are other places where the pollution generated by weapons work has leaked and migrated to ordinary neighborhoods. Currently, there are residential areas around St. Louis where radioactive pollution from the Cold War is a serious concern.

      A great deal of nuclear weapons work was carried out in the St. Louis area during the Cold War. The U.S. Army Corp of Engineers (ACE) has been cleaning up contamination in industrial and commercial sections of the St. Louis area for years. Coldwater Creek runs through an area in St. Louis where waste from the nuclear weapons work was stored. The creek continues on through residential areas and ultimately runs into the Missouri River. Federal authorities has acknowledged that the creek contains radioactive contamination and have included it in their cleanup work. One major ongoing question is just how far the nuclear contamination was spread by the creek.

        Past and present residents of the area claim that contamination from the creek spread into their neighborhoods during periods when the creek flooded. They have argued for broad sampling of houses and yards for contamination. They also claim that there an are unusually large number of cancer cases and other health problems that may be linked to radioactive exposure. Last fall, the Missouri Department of Health and Senior Services sent a letter to federal officials stating that a significantly higher occurrence of leukemia in areas around Coldwater Creek had been found. The MDHS said that it had not determined whether or not the leukemia cluster had been caused by contaminants from the nuclear weapons work. It requested federal assistance for further research on the subject.

       Thorium, the radioactive isotope of hydrogen, is the primary pollutant being discussed. The ACE has, for the first time, admitted that thorium has been discovered in the ground of three neighborhoods around the creek. The federal authorities say that the thorium is at least six inched below the ground and is not a threat. The ACE says that it intends to include thorium found in residents yards in its cleanup. They are going to be doing more sampling in the general area where the thorium has been found and expect to find more.

       The ACE has also found lower levels of thorium contamination in three other places along the creek including two public parks. The contaminated areas of the parks have been fenced off according to the city manager of Hazelwood. The non-contaminated areas of the parks have remained open for public use. However, the city manager is considering closing the rest of the parks because of public protests.

        A citizens group has reacted to the admission from the ACE by saying, ” “We have proof from the federal government that thorium is in people’s backyards.” The existence of these sites is a sad reflection on environmental priorities versus military priorities in our country. Some of the hundreds of billions of dollars that the federal government spends each year on defense should be shifted to cleaning up the radioactive contamination from the production of nuclear weapons during the Cold War.

       I have blogged recently about nuclear fusion as an alternative to nuclear fission for the generation of electricity. There is a huge international fusion research project underway in France called ITER based on the confinement of super hot plasma in a donut shaped configuration called a tokomak. I have blogged about problems they are having with money and management. I have also blogged about universities and companies that are working on smaller and cheaper fusion reactor designs. One of them may be able to construct a commercial prototype fusion power generator before the ITER project is completed. ITER is not even intended to actually generate more power than it consumes for more than a few second. Today, I am going to blog about another entry into the small practical fusion power generator race.

       The Helion Fusion Engine is being developed by a trio of institutions. The University of Washington in Seattle is carrying out basic science research on the project. MSNW LLC was created for obtaining grants to develop the technology. Helion Energy was created to commercialize the technology with venture capital.

       The Helion Fusion Engineis a new approach that is midway  between the steady state confinement of a super hot plasma like the ITER tokomak design and the inertial confinement approach where a pellet of fuel is bombarded with a sphere of laser beams. In the Helion reactor, fuel is injected into a chamber where it is compressed by magnetic fields and fuses. Energy of the expanding cloud of particles that results is converted directly into electricity. The system fuses a batch of fuel about once a second.

        One of the selling points for this reactor is the fact that it does not use nor does it produce radioactive isotopes. It also emits no carbon dioxide. The fuel it uses consists of Helium three which is missing a neutron and deuterium which is hydrogen with an extra neutron. Deuterium comprises more than one one-hundreth of one percent of ocean water. Helium will be captured from the exhaust of the reactor and recycled. Fuel will not be a major expense and no significant waste is produced.

Benefits of the Helion fusion reactor from the Helion Energy website:

• Magneto-Inertial Fusion: By combining the stability of steady magnetic fusion and the heating of pulsed inertial fusion, a commercially practical system has been realized that is smaller and lower cost than existing programs.
• Modular, Distributed Power: A container sized, 50 MW module for base load power generation.
• Self-Supplied Helium 3 Fusion: Pulsed, D-He3 fusion simplifies the engineering of a fusion power plant, lowers costs, and is even cleaner than traditional fusion.
• Magnetic Compression: Fuel is compressed and heated purely by magnetic fields operated with modern solid state electronics. This eliminates inefficient, expensive laser, piston, or beam techniques used by other fusion approaches.
• Direct Energy Conversion: Enabled by pulsed operation, efficient direct conversion decreases plant costs and fusion’s engineering challenges.
• Safe: With no possibility of melt-down, or hazardous nuclear waste, fusion does not suffer the drawbacks that make fission an unattractive alternative.

         Helion claims that funding of two hundred million dollars would be sufficient for them to build a pilot commercial fifty megawatt power plant by 2019. Then they could go into commercial production by 2022.  Helion estimates that its approach will yield commercial nuclear fusion in one tenth the time of the ITER approach and at one thousandth the cost. With five different organizations all working on small economical nuclear fusion reactors, fusion power may finally be an idea whose time has come.
