The Samson Option states that Moshe Dayan gave the go-ahead for starting weapon production in early 1968, putting the plutonium separation plant into full operation.
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.
