Does nuclear energy produce no CO2 ?
A look at the full Uranium cycle
Maintaining the tailings ponds, with more diesel powered machinery
Hard rock ores, such as quartz conglomerates and granites, are approximately 3 to 4 times more energy-intensive than soft rock ores (limestones and shales) to crush.
The dissolved uranium solution, including other metals, is then treated with amines dissolved in kerosene to selectively separate the uranium, which is then precipitated out of solution using ammonia, forming Ammonium di-uranate, or "yellowcake"
The Uranium hexafluoride gas is then compressed and transported in cylinders to be enriched
Low-enriched (3.6%) Uranium hexafluoride gas is then transported to the fuel fabrication plant
For every tonne of Uranium in the fuel, up to 2 tonnes of Zirconium alloy are needed for the tubes
Spent fuel rods normally spend six months in cooling ponds located within the reactor building, so that short-lived radio-activity can decay, making the material safer to handle
This is “The Pond” at Sellafield in the UK. Spent fuel is kept under water until it is reprocessed. This keeps it cool and acts as a radiation shield
Recovered Plutonium and mixtures of Plutonium and Uranium oxides (MOX) are sent by road back to the fuel fabrication facility to be used in new fuel rods.
This is a security policeman –well, it does say POLICE on his bag.I do hope everything is alright.
