British Scientist Predicted Nuclear Power Station Problem
Dr. Peter Harrop, still a practicing scientist, explains, "When the outer building of the Japanese Fukushima No 1 reactor massively exploded, it was speculated that this was caused by hydrogen emitted from the overheated zirconium fuel cladding being in contact with cooling water. It is possible that, if this is true, just one of the contributory factors was that the zirconium alloy and its protective oxide film had built up neutron damage over nearly 40 years. Indeed the plant was about to be decommissioned in one month, having been commissioned in 1971."
These days Dr. Harrop is out of the nuclear business but still involved in the science of electricity generation both large and small scale. His Cambridge company IDTechEx Ltd stages the world's largest events on Printed Electronics, encompassing printed flexible solar cells that can even be wrapped around buildings, cars and ships. The next such event is Printed Electronics and Photovoltaics Europe in Dusseldorf on 5-6 April.
He notes, "I think there will always be space for several forms of electricity generation but governments must show consistency of purpose in supporting them in the early stages. The Japanese and Spanish governments have suddenly collapsed financial support for photovoltaic generation in the past, destroying nascent industries and associated employment and wealth creation. It is feared that the British government and some others are about to make the same mistake."
He thinks that wind generators on land in countries like the UK where the wind rarely blows are merely gesture politics and he is pleased to see new ones sited in the North Sea where the wind rarely ceases to blow. However, he still supports nuclear power, noting that, "The UK and France, for example, have a superb record of safety with their nuclear power stations because they are correctly over designed and properly maintained and sited. Nuclear power is one of the least-worst solutions for power hungry countries wishing to avoid global warming and a sharp contrast to the massive human and planetary toll of coal power, for example. Millions of people are injured by the silicosis, cancer and accidents in coal mining and from breathing the emissions from burning coal and the planet is severely impacted. It would be a shame to revert to that because the press tend to keep it quiet." He supports the UK building more nuclear power stations, including the best modern water cooled versions.
"One day we shall be able to fully follow the advice of Edison that electricity should only be generated where it is used. Then there will be no power stations. Progress is gradual but essential on that one," he tells us.
