Nuclear power station of Vandellós II

The Vandellós II nuclear power plant is a power plant. The facility is located on the shores of the Mediterranean Sea, in the municipality of Vandellós, in the province of Tarragona. The national participation in the construction and supply of equipment represented more than 89% of the total, which represented the highest percentage achieved in Spain for this type of project.

The plant as a whole, which has a nuclear pressurized water reactor, consists of several main buildings: containment building, fuel, auxiliary and turbine building. In addition, it is equipped with a central cooling water intake pipe, formed by reinforced concrete caissons, which goes into the sea. The cooling water is discharged through an open channel that empties into the coastline. This maritime location guarantees the availability of an inexhaustible source of water.

[La central nuclear de Vandellós II pertenece a la llamada tercera generación, que constituye la vanguardia tecnológica en este campo de la energía nuclear.]

The companies that own the nuclear plant are the electricity companies: Endesa Generación (72%) and Iberdrola Generación (28%). After the Prior Authorization approved on October 7, 1976, the Authorization for Commissioning was granted by the MINER on August 17, 1987, after the approval of the Construction Authorization in January 1981, and the plant began its operation. commercial on March 8, 1988. In 2003, gross electric power generation reached 8.56 billion kWh with a load factor of 89.9% and an availability factor of 89.88%.

Characteristics of the Vandellós II nuclear power plant

This nuclear power center works is Westinghouse design. Its thermal power is 2,775 thermal megawatts and its gross electrical power of 1,087 MWe, much more than the Vandellòs I for being of newer technology.

The nuclear reactor of the Vandellós II nuclear power plant is a thermal reactor of the PWR (nuclear pressurized water reactor) type. The nuclear fuel used is uranium in the form of uranium dioxide, slightly enriched (3% -5%). It contains one hundred and fifty-seven elements, of which each carries two hundred sixty-four fuel rods on a 17 x 17 matrix.

The dose of radioactivity (sum of artificial radioactivity, due to the central and other anthropogenic origins, and natural radioactivity, which always leaves the soil naturally) per annual individual of 2008 was 1.96 mSv (milli sievert).

Spent fuel is stored, as is usually done in many nuclear power plants in swimming pools that are inside the same nuclear plant. Pool water serves to cool used nuclear fuel that continues to emit waste heat and as a further barrier to radiation protection from fuel. Medium and low radioactivity residues are transported in drums in the Andalusian town of El Cabril, where they are stored until all their radioactivity has been released and then treated as normal waste.

Electricity production

Its gross production varies year after year, but it is usually between 5,000 GWh (giga watt hour) and 10,000 GWh approximately.

The plant's annual electricity production is equivalent to 30% of the electricity consumed in Catalonia. The entry into operation of the Vandellós II Replica Simulator is noteworthy, where the annual re-training of licensed operators will be carried out, the review of stop procedures to optimize the operations and time spent during recharging operations, plant maneuver tests scheduled for maintenance intervention during the cycle and exams for Obtaining Operating Licenses.

After the Prior Authorization approved on October 7, 1976, the Authorization for Commissioning was granted by the MINER on August 17, 1987, after the approval of the Construction Authorization in January 1981, and the plant began its commercial operation on March 8, 1988.
