[2] Romania (as the Romanian People's Republic) started a nuclear research program in 1949, focusing on radioactive isotopes in medicine and industry.

[3] The defection of Securitate general Ion Mihai Pacepa in 1978 was, according to Lucia Hossu Longin, at least in part related to the order given to him by Ceaușescu, to obtain the technology for a certain element needed in the development of nuclear weapons.

[4] According to Ionuț Purica, former director of the Nuclear and Radioactive Waste Agency, Romania had 26 kg of plutonium from the Măgurele reactor in the 1980s.

[6] In July 1989, Hungarian Foreign Minister Gyula Horn accused Romania of posing military threats to Hungary through its nuclear and medium-range missile programs.

[7] Other scholars have claimed that Romania was pursuing nuclear technology as a hedge, such that it could muster a weapon should the need arise.

[11] During Nicolae Ceaușescu's rule, Romania was involved in negotiations with multiple states on the open market of nuclear technology and materials.

"In addition to playing Britain and France off against each other in the mid-1960s, Romania negotiated for nuclear power plants with Canada, Italy, Sweden, the United States, and West Germany."

[1] After the 1989 Romanian Revolution, Romania announced to the International Atomic Energy Agency (IAEA) that it had 100 mg of plutonium separated in 1985 at the Pitești Nuclear Research Institute.
