""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." "Although the closed plant has
not been officially named for national security reasons, the Guardian
understands it is known as A45. It makes enriched uranium components for Trident
nuclear warheads and has recently been helping to make the uranium fuel for the
Astute generation of nuclear-powered submarines.""
