Some interesting things in here if you just poke around. For example:
Zalman Shapiro
Zalman Mordecai Shapiro (12 May 1920 – 16 July 2016) was an American chemist and inventor. He received 15 patents, including a 2009 patent on a process to make commercial production of diamonds cheaper,[1] and played a key role in the development of the reactor that powered the world's first nuclear powered submarine, the Nautilus.[2][3]

The Apollo Affair
The Apollo Affair was a 1965 incident in which a US company, Nuclear Materials and Equipment Corporation (NUMEC), in the Pittsburgh suburbs of Apollo and Parks Township, Pennsylvania was investigated for losing 200–600 pounds (91–272 kg) of highly enriched uranium, with suspicions that it had gone to Israel's nuclear weapons program.
In the movie Sum of All Fears, after determining that the Baltimore nuclear bomb's plutonium came from Savannah River in 1968, Jack Ryan asked Spinnaker via smartphone where the plutonium went. This is a fictitious reference to the Apollo Affair. In the movie an Israeli A-4 carrying a plutonium bomb is shot down, its bomb later recovered by scrap dealers, and its plutonium sold to neo-Nazis (Palestinian terrorists in the book).
