Nuclear power stations will not be built and running for a decade or two or more. The Government has delayed it by years and are escalating costs due to excessive H & S. Remember the Energy department is run by loony and sometimes criminal Lib Dems, who as part of their climate change religion consider nuclear power Beelzebub itself.

This is why several companies have pulled out of building the nuclear plants the remaining European company EDF is now sitting on the fence on whether they will go ahead.

While the rest of the world is moving on nuclear technology, where we have no development program we will essentially be building last generation technology with its inherent problems, which may include not enough uranium fuel as there is predicted to be a serious world shortage by 2025. The next generation Thorium power station, known world reserves will last for over 1,000 years for present and predicted energy growth requirements.
Thorium power stations are inherently much safer and also produce a fraction of the waste with much shorter half-life particles compared to uranium. Thorium fuel needs a primer which can be current nuclear waste which it turns into usable safer material as well as generating power. Fortunately Cumbria voted out us burying it as future generations are going to want to use it.
Again it is the rising industrial stars of the 21st century in Asia that are leading development, with no major research programs in Western countries where they are all trying their hardest to see who can be the poorest 3rd world country by the end of the 21st century, but at least if the politicians have their way we will all be equally poor, with the same equality of misery.
