Garigliano
Location: Italy
Operator: Enel SpA
Configuration: 1 X 160 MW BWR
Operation: 1964 (ret 1982)
Reactor supplier: GE
T/G supplier: ??
EPC: GE
Quick facts: On 16 Sep 1959, the World Bank made a loan equivalent to $40mn for the construction of Italy's first nuclear power plant. This financed almost two-thirds of the cost of construction, including civil works, a substation and 100km of transmission line. Societa Elettronucleare Nazionale (SENN) was designated by the Italian government as plant owner and operator. The site is on the Garigliano River, between Rome and Naples. Internuclear Company and Kennedy & Donkin were engineering consultants and GE was the general contractor through its Swiss offices. The 160ft diameter steel sphere served as the pressure vessel. Construction started in Nov 1959 and the unit started-up in Jan 1964. The plant was transferred to Enel in 1966 and operated until 1978 when damage to one of the secondary steam generators forced it offline. Garigliano never restarted.

Operation: 1979
Reactor supplier: Siemens
T/G supplier: Siemens
EPC: Siemens, Heitkamp
Quick facts: The final construction permit for Gösgen was issued on 31 October 1972 and construction started the following summer After some last-minute delays, commissioning was authorized on 29 Sep 1979 and the unit went commercial on 1 Nov 1979. The plant has been substantially uprated from its original 970 MW capacity. The site in in Däniken, Solothurn,on the Aar River. KKG is owned by Alpiq (40%), Axpo (25%), the city of Zurich (15%), Centralschweizerischen Kraftwerke (12.5%), and Energie Wasser Bern (7.5%).

Latina
Location: Italy
Operator: Enel SpA
Configuration: 1 X 160 MW Magnox
Operation: 1963 (ret 1990)
Reactor supplier: TNPG
T/G supplier: Parsons
EPC: TNPG, Groupe Torno
Quick facts: This shows Eni Director General Enrico Mattei and other officials visiting the Latina site in 1962. The plant was one of two Magnox reactors exported from the UK. Construction started in Oct 1958 and the unit was connected to the grid in May 1963. It was ordered by SIMEA, an ENI subsidiary. The UK Atomic Energy Authority consulted on safety features. Latina was shutdown in Dec 1987 and is being decommissioned by British Nuclear Group and Sogin, the former nuclear division of Enel.

Zwentendorf
Location: Austria
Operator: GKW Tullnerfeld GmbH
Configuration: 1 X 765 MW BWR
Completed: 1978
Reactor supplier: Siemens
T/G supplier: Siemens, Elin
EPC: Siemens, Heitkamp
Quick facts: This plant was completed but never went into operation. Planning started in 1967 and construction began in 1972. The operating company was led by Verbund with a 50% stake and seven Austrian provinces owned shares.
