In Rosyth Dockyard, Fife, Scotland, are the decommissioned nuclear submarines of the Royal Navy. Dreadnought, the four Polaris nuclear missile submarines, Conqueror and Vanguard, surrounded by barbed wire and regularly monitored. That was some time ago and there may be more now in the basin, slowly rotting away, with the nuclear reactors still intact inside them. They need to be kept in the water, to keep the nuclear reactors cool, as they still produce heat. I have no idea, what radioactivity goes into the basin, then the Forth from these hulks. They have been sitting there for decades and yet, the UK Government wants to built more nuclear submarines? Even the so-called peacenik Jeremy Corbyn, wants to renew the Trident nuclear ballistic missile submarine fleet! When will this stupidity ever end?
