In this recent article the German News outlet ‘Deutsche Welle’ expose the link between civil nuclear and nuclear weapons. Nuclear ‘energy’ is a political choice.

As a country, the UK will not meet future climate change targets unless we figure out how to heat and cool our cities without burning vast amounts of natural gas. Towns and rural areas also need to decarbonise their heat supply, of course. But cities being what they are, the greatest amount of energy going into keeping people and equipment at reasonable temperatures are in cities. Renewable heat only supplying around 5 per cent on annual heat demand in the UK, and isn’t increasing anywhere near as much as needed. The UK government has introduced a world-leading Renewable Heat Incentive (RHI), which paid out cold hard cash to households and businesses to produce heat from renewable sources, with 90 per cent of installation being biomass. But the RHI at a household level has not been nearly as successful as comparative schemes for solar PV, likely due to a higher hassle factor, despite being potentially more financially lucrative. Highly concentrated heat demand allows heat networks in cities to be economically viable, compared to towns or suburbs. Heat networks are essentially pipes of hot water, much like gas pipes. In cities, these networks can transport heat to where it is needed from large heat productions plants, or from processes which make waste heat in a city, like subways, sewers, or digital heavy infrastructure. one solution which we’re not talking about, which perhaps we should be. It’s very low carbon, creates no air pollution, produces heat easily at higher temperatures, and doesn’t put extra demand upon the power network. That solution is nuclear – but not as you might know it. There are some grasping projections of how we could build small modular nuclear power reactors, place these near high heat demands (cities or industry) and reap almost continuous large volumes of high grade heat. But our electricity grid is rapidly decarbonising – so what if we did away with the electricity generation of nuclear and just sought the heat generated?
