Nuclear power is the most efficient, safest and most environment friendly source of energy.


This blog compiles facts that make nuclear energy the clear choice for powering our future.

I have NO connection with the nuclear power industry and I have never had any connection with the nuclear power industry.

I have created this blog because I believe we are in dire need of drastically reducing our carbon emissions. Coal fired power plants are the single largest producer of CO2. Nuclear power is the most efficient, safest and most environmentally friendly source of energy available.

Coal Is Bad

Alex Gabbard makes it clear in this ORNL article. Coal fired power plants are a bigger danger to your health and the future of our planet than nuclear power plants. Coal fired power plants release more radiation and more CO2 into the atmosphere than a nuclear power plant. Yet 52% of our energy comes form coal fired power plants, while only 15% is created by nuclear energy.

The Oak Ridge National Laboratory is the Department of Energy’s largest science and energy laboratory.


  • "Power to Save the World; The Truth About Nuclear Energy" by Gwyneth Cravens, 2007 Finally a truthful book about nuclear power. This book is very easy to read and understand.
  • ENVIRONMENTALISTS FOR NUCLEAR ENERGY book: Fossil fuels such as coal oil, and gas, massively pollute the Earth's atmosphere (CO, CO2, SOX, NOX...), provoking acid rains and changeing the global climate by increasing the greenhouse effect, while nuclear energy does not participate in these pollutions and presents well-founded environmental benefits. Renewable energies (solar, wind) not being able to deliver the amount of energy required by populations in developing and developed countries, nuclear energy is in fact the only clean and safe energy available to protect the planet during the XXI st century. This book answers essential questions about nuclear safety, the Chernobyl accident, the public health problems our society has to face, viable solutions for nuclear waste, the benefits of clean nuclear energy for the environment, and important information about the future of our planet.

Mass Extinction

The largest mass extinction of life occurred 251 million years ago when the atmospheric carbon levels rose to near 1000 parts per million, the ocean became anoxic (lacking oxygen). This allowed hydrogen sulfide gas to bubbled up from the bottom of the ocean and 95% of all life on earth died.

Recycling nuclear fuel

Everything, including yourself, is made of atoms. All atoms have nuclei. You have many atomic nuclei inside yourself since you are made of atoms. The simplest nucleus is one proton. That would be a hydrogen atom. An oxygen atom has 8 protons and either 8, 9 or 10 neutrons in its nucleus. All other nuclei also have neutrons. Uranium has 92 protons and either 143 or 146 neutrons. If it has 143 neutrons it is U235. If it has 146 neutrons, it is U238. Nuclear fuel is only 2% to 8% U235, the kind that fissions/divides, providing energy. The rest is U238 that doesn't fission. A nuclear reaction happens when a neutron is captured by a nucleus. If a U235 nucleus captures a neutron, the nucleus and the atom split

approximately in half and 3 more neutrons are released because the 2 smaller nuclei don't need so many neutrons. If a U238 nucleus captures a neutron, it ejects an electron and the neutron becomes a proton. The U238 thus becomes Plutonium 239. [In a power plant, Plutonium 239 [Pu239] quickly captures another neutron and becomes Pu240. Pu239 makes good bombs but Pu240 bombs fizzle and are militarily useless.] Plutonium is fissionable, which means that plutonium is a good fuel. If you add Thorium to the fuel, you can make more fissionable uranium. If a Thorium atom nucleus captures a neutron, it ejects an electron and the neutron becomes a proton. The Thorium atom thus becomes U233. U233 is fissionable.

Depending on the design of the reactor and the mix of the fuel, the fuel % in the reactor can either grow or shrink. It is kind of like the fuel gauge can go either up or down, but it is more like the reactor can run hotter or cooler over time. The temperature is kept constant by adjusting the control rods. A breeder reactor is a reactor designed to make the fissionable part of the fuel load grow rapidly. Normally, fuel is left in the reactor for about some number of years, or some percentage of the fuel is replaced each year. The reprocessing step sorts out the fuel and puts the percentage of fissionable fuel back to the starting percentage. In the process, plutonium may be removed and either wasted or used as fuel. If we add thorium to the fuel, we can make more uranium than we put in. Since the earth contains more than twice as much thorium as uranium, it would be wise to make thorium into uranium. By reprocessing nuclear fuel, we get an enormous, many centuries long fuel supply without doing much mining. Only minute amounts of un-enriched uranium or thorium need to be added to lower the percentage of fissionable fuel. The products of fission are also removed when fuel is reprocessed. These are just other atoms that are no longer useful as fuel. The quantity is very small. We should reprocess fuel to keep the fuel load at the correct percentage of fissionable fuel for the particular reactor design. Instead, we go through the expensive process of making more "virgin" fuel for each new fuel load. This greatly increases the price you pay for electricity. We are not reprocessing nuclear fuel for political reasons.
