Fusion “Dream” is Toxic Nightmare

The fusion dream is a toxic nightmare which throws billions of £££££s of public money away in the plan to create another nuclear treadmill from which there is no getting off..


Fusion reactors have long been touted as the “perfect” energy source.
Proponents claim that when useful commercial fusion reactors are developed,
they would produce vast amounts of energy with little radioactive waste,
forming little or no plutonium byproducts that could be used for nuclear
weapons. These pro-fusion advocates also say that fusion reactors would be
incapable of generating the dangerous runaway chain reactions that lead to a
meltdown-all drawbacks to the current fission schemes in nuclear power
plants. As we move closer to our goal, however, it is time to ask: Is fusion
really a “perfect” energy source? After having worked on nuclear fusion
experiments for 25 years at the <http://www.pppl.gov/&gt; Princeton Plasma
Physics Lab, I began to look at the fusion enterprise more dispassionately
in my retirement. I concluded that a fusion reactor would be far from
perfect, and in some ways close to the opposite. fusion reactors that burn
neutron-rich isotopes have byproducts that are anything but harmless:
Energetic neutron streams comprise 80 percent of the fusion energy output of
deuterium-tritium reactions and 35 percent of deuterium-deuterium reactions
Now, an energy source consisting of 80 percent energetic neutron streams may
be the perfectneutron source, but it’s truly bizarre that it would ever be
hailed as the ideal electrical energy source. In fact, these neutron streams
lead directly to four regrettable problems with nuclear energy: radiation
damage to structures; radioactive waste; the need for biological shielding;
and the potential for the production of weapons-grade plutonium 239-thus
adding to the threat of nuclear weapons proliferation, not lessening it, as
fusion proponents would have it. In addition, if fusion reactors are indeed
feasible-as assumed here-they would share some of the other serious problems
that plague fission reactors, including tritium release, daunting coolant
demands, and high operating costs. There will also be additional drawbacks
that are unique to fusion devices: the use of fuel (tritium) that is not
found in nature and must be replenished by the reactor itself; and
unavoidable on-site power drains that drastically reduce the electric power
available for sale.”
