Garona
Location: Burgos
Operator: Nuclenor SA
Configuration: 1 X 466 MW BWR
Operation: 1971 (ret 2012)
Reactor supplier: GE
T/G supplier: GE
EPC: Ebasco, GE
EPC: Bechtel, Iberdrola
Quick facts: The Santa María de Garoña NPP is on the Rio Ebro in the Tobalina valley. On 2 Mar 1957, Electra de Viesgo and Iberduero created Centrales Nucleares del Norte SA and in Aug 1963, the venture was permissioned to build Spain's first commercial nuclear plant, planned as two 250-MW units. In the end, a single BWR was installed. Works began in Sep 1966 and concluded in Nov 1971 with commercial operation on 2 Mar 1971. The Garona unit was taken offline for the last time on 26 Dec 2012 after passage of new Spanish legislation substantially altering the financial treatment of power generation and spent nuclear fuel. Nucleanor stated that the new taxes would cost €153mn in 2013 and lead to losses that would bankrupt the company.

Jose Cabrera
Location: Guadalajara
Operator: Union Electrica Fenosa SA
Configuration: 1 X 160 MW PWR
Operation: 1968 (ret 2006)
Reactor supplier: Westinghouse
T/G supplier: Westinghouse
EPC: Gibbs & Hill
Quick facts: Jose Cabrera, aka Zorita, was closed on 30 Apr 2006 by ministerial decree. It is the first Spanish nuclear plant to be closed early due to political considerations, in this case pressure from the Guadalajara government resulting in a 2002 decision by the Nuclear Safety Council to grant a 4yr operating license. Plant construction started in Jul 1965 and startup was in Jun 1968:  the 1-loop design is unique in Europe. In Feb 2010, Fenosa transferred ownership to Enresa and in Jul 2010, Westinghouse was selected to dismantle and segment the vessel internals. At the time, decommissioning was expected to cost €135mn.

Lemóniz
Location: Vizcaya
Operator: Iberdrola
Configuration: 2 X 930 MW PWR
Operation: n/a (cancelled 1994)
Reactor supplier: WH
T/G supplier: WH
EPC: Bechtel, Iberdrola
Quick facts: This coastal site is about 30km from Bilbao and was the target of a number of attacks by Basque separatists starting in Dec 1977. Construction was stopped in 1981 with both units essentially complete and the plant was formally terminated in Dec 1994. Iberdrola received a total of €2.85bn in compensation.

Configuration: 2 X 975 MW BWR
Operation: n/a (cancelled 1994)
Reactor supplier: GE
T/G supplier: GE
EPC: AETEA, Empresarios Agrupados, Ebasco, GE
Quick facts: Construction stopped in 1983 following a decision by a new Spanish government to discontinue nuclear plant development. The plant was formally terminated in Dec 1994. Units 1&2 were estimated to be 70% and 60% complete, respectively. Endesa received €2.56bn in compensation.

Vandellos-I
Location: Tarragona
Operator: Hispano Francesa de Energia Nuclear SA (Hifrensa)
Configuration: 1 X 500 MW GCR
Operation: 1972 (ret 1990)
Reactor supplier: CEA
T/G supplier: Alsthom
EPC: Societe pour l'Industrie Atomique, Groupe Constructeurs Francaise
Quick facts: This graphite-moderated gas-cooled reactor was modeled after the first two St Laurent-des-Eaux units in France. Construction started in Jun 1968 and the unit went commercial on 2 Aug 1972. The unit suffered a serious turbine fire in Oct 1989 and, not long thereafter, the decision was made to close the plant. Its lifetime load factor was just over 73%. The core and the steam generators were co-located inside a pre-stressed concrete pressure vessel and reactor vessel also housed blowers and auxiliary equipment. Enersa completed a Level 2 dismantling between Feb 1998 and Jun 2003 leaving only the inside of the reactor and the supporting structure for later removal.
