Lasrick writes "The Guardian has an exclusive story regarding a secret uranium-enriching plant in the UK that was closed due to safety fears. From the article: 'A top-secret plant at Aldermaston that makes enriched uranium components for Britain's nuclear warheads and fuel for the Royal Navy's submarines has been shut down because corrosion has been discovered in its 'structural steelwork', the Guardian can reveal.
The closure has been endorsed by safety regulators who feared the building did not conform to the appropriate standards. The nuclear safety watchdog demands that such critical buildings are capable of withstanding 'extreme weather and seismic events,' and the plant at Aldermaston failed this test.
It has set a deadline of the end of the year for the problems to be fixed.'"
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
