Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

A waste of waste - The Guardian


Why bury nuclear waste, when it could meet the world's energy needs?
[...]
As a result of shutting down its nuclear programme in response to green demands, Germany will produce an extra 300 million tonnes of carbon dioxide between now and 2020(1). That's almost as much as all the European savings resulting from the energy efficiency directive(2). Other countries are now heading the same way. These decisions are the result of an almost mediaevel misrepresentation of science and technology. For while the greens are right about most things, our views on nuclear power have been shaped by weapons-grade woo.
[...]
In his book Prescription for the Planet, the environmentalist Tom Blees explains the remarkable potential of integral fast reactors (IFRs)(11). These are nuclear power stations which can run on what old nuclear plants have left behind. Conventional nuclear power uses just 0.6% of the energy contained in the uranium that fuels it. Integral fast reactors can use almost all the rest.
[...]
The material being reprocessed never leaves the site: it remains within a sealed and remotely-operated recycling plant. Anyone trying to remove it would quickly die. By ensuring the fissile products are unusable, the IFR process reduces the risk of weapons proliferation. The plant operates at scarcely more than atmospheric pressure, so it can't blow its top. Better still, it could melt down only by breaking the laws of physics. If the fuel pins begin to overheat, their expansion stops the fission reaction. If, like the Fukushima plant, an IFR loses its power supply, it simply shuts down, without human agency.

I don't want to end up quoting the entire article -and I am unable to pass a qualified judgment on the technology, but there are plenty of references in the article.
Is anyone familiar with it?

Earth provides enough to satisfy every man's need, but not every man's greed. Gandhi
