 almaraz Nuclear Power Plant, Spain

Almaraz Nuclear Power supplied 16,000 million kWh annually throughout Spain.

The Alamarz Nuclear Power Plants I and II are located in the municipality of Almaraz de Tajo (Cáceres). The land owned by the central cover an area of 1,683 hectares located in the municipalities of Almaraz, Saucedilla and Serrejón Romangordo.

The Almaraz consists of two light water reactors of 2686 MW pressurized thermal, each with three cooling circuits, and manufacturing and construction is a Spanish contribution greater than 80 100. Both units use as fuel slightly enriched uranium oxide and its electrical output is 977 MW and 980 MW of respectively.

Process Construction of the Nuclear Plant

The project Almaraz Nuclear Power Plant was undertaken in the late seventies and completed in the early eighties, three major utilities: Hydroelectric Spanish, Sevillana de Electricidad and Madrileña Electrical Union, equally. Today, after the process of reorganization of the electricity sector, its owners are Iberdrola (52.687%), Endesa (36.021%) and Union Fenosa (11,292%). On 10 May 1973 the first concrete was placed in the central slab containment building of Unit I and two years later its dome was closed. In Unit II, the equivalent dates are September 1973 and July 1976. In this interval advanced civil works, including the building of turbines and dam for the reservoir cooling, then go to the stage of assembly, testing and start up.

81% of total construction and assembly of equipment Almaraz NPP was carried out by Spanish companies. Unit I entered commercial service on May 1, 1981; Unit II did on 8 October 1983. The Almaraz Nuclear Power Plant is designed as a central base, ie, uninterrupted operation, and is able to ensure an annual supply of 16,000 million kWh.

Production of the Two Nuclear Plants

In 2008, the combined gross output generated by both units was of 16,089 million kilowatt-hours. The gross electric energy accumulated since the Central began operating in May 1981 to 31 December 2008 is 370,230 million kilowatt-hours.
