The linked conundrum of nuclear weapons and nuclear power

John will look, in layman’s terms, at how modern nuclear reactors work, the prospects for a new generation of nuclear power stations, in Britain and worldwide, and how, if they are built, to make them as safe and secure as possible. Where are the catches in this ‘clean’ power generation, and how can the potential link of parts of the nuclear fuel cycle to the production of nuclear weapons be internationally policed and controlled. Why has the spread of nuclear power generation not led to the wider spread of nuclear weapons predicted in the 1960s? To a remarkable degree, so called ‘non proliferation’ has worked to date, but will the Non Proliferation Treaty be fit for purpose in the 21st Century, and what are the key indicators to look for to judge its success or failure?
