The News That Matters about the Nuclear Industry

NUCLEAR TECHNOLOGY CHALLENGES – theme for July 2012

The decline of the nuclear industry poses huge challenges –  nuclear experts need not fear unemployment.

RADIOACTIVE WASTE DISPOSAL.  If all nuclear reactors stopped today, and all nuclear weapons were “turned off”, the world would still be left with a massive unsolved problem of disposing of the wastes.

BURYING THE CORPSES of nuclear reactors – (they prefer that nice word “decommissioning”) – a huge part of the unsolved waste problem.

ALTERNATIVE TECHNOLOGIES

Renewable energy is taking over –  it is supposed to be “clean and green”. And digital communications are also taking over the world.

But at present, both of these require “rare earths”

RARE EARTHS     On the one hand, these play a  part in the renewable energy future, for example in making wind turbines, and in electric car batteries.  Rare earths are a group of 17 chemical elements ( yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium)    Rare earth metals and alloys that contain them are used in many devices that people use every day such as: computer memory, DVD’s, rechargeable batteries, cell phones, car catalytic converters, magnets, fluorescent lighting and much more.  http://geology.com/articles/rare-earth-elements/

On the other hand, – the downside of rare earths  -  in the mining and processing of these rare earth minerals, radioactive wastes are produced.
