Meanings
-
(uncountable, usually) The transuranic chemical element with atomic number 94 and symbol Pu: a silvery-gray fissile radioactive actinide metal that tarnishes when exposed to air.
For 75 years, it has fulfilled a wide range of roles: producing weapons-grade plutonium for early atomic weapons in the aftermath of the Second World War; the world's first commercial nuclear power station supplying electricity to the National Grid; reprocessing and storage of nuclear fuel; and the processing of lower grades of radioactive waste for off-site storage.
