Uranium and Nuclear Power

Uranium and Nuclear Power

This article relates to Yellowcake

According to theUranium Information Center:

• Over half of the world's production of uranium is from mines in Australia and Canada.
• 8 mining companies account for almost 80% of production.
• Nuclear energy supplies over 16% of the world's electricity.
• 31 countries use nuclear energy to generate electricity.
• 80% of France's electricity is from nuclear power.
• Over 12,000 reactor years of operational experience have been accumulated since the 1950s by the world's 440 nuclear power reactors (and nuclear reactors powering naval vessels have clocked up a similar amount).
• The Chernobyl meltdown was in a reactor that lacked the basic engineering provisions necessary for licensing in most parts of the world. When the reactor at the Three Mile Island plant in Harrisburg, PA, suffered a similar malfunction in 1979 the effects were contained and no-one suffered any harm or injury.
• In terms of cost, it is often still cheaper to mine and burn coal, but if carbon dioxide emissions are built into the equation, nuclear energy is cost efficient.
• Waste management is built into the cost of producing nuclear energy.
• Generating enough nuclear energy for 100 people in the western world for a year creates about 3 kg of spent fuel.
• Spent fuel is transferred to a large storage pool where it remains for up to 50 years.
• After 40 years, the spent fuel has only one thousandth of its initial radioactivity remaining, making it very much easier to handle and dispose of.
• Many homes have smoke detectors which depend on a tiny amount of americium, derived from plutonium made in a nuclear reactor.
• In the developed countries, it is estimated that about one half of all people will be treated withnuclear medicine at some stage of their lives.
