CONSIDERING THE WHOLE LIFETIME OF THE PLANTS THE RANKING FOR COFRENTES NPP IS Nº 27 OF 441 NNPP IN THE WORLD


The sustainability of nuclear The sustainability of nuclear energyenergy

The Environment• Does not produce CO2• Does not release combustion fumes off site• Does not emit Sulphur Oxides or Nitrogen Oxides (acid rain)• Does not consume oxygen in combustion• Amount of fuel: The same amount of electricity is produced with 20 tons of

Uranium as with 2 million tons of coal or 1 million cubic metres of gas.

For example, the Cofrentes Nuclear Power Plant prevents every year the emission of some 9 million Tn of CO2 and the importing of approximately 14 million barrels of oil.


EXTERNAL AND INTERNAL CONTROL OF COFRENTES NPP

• THE REGULATORY BODY IN SPAIN IS THE “CONSEJO DE SEGURIDAD NUCLEAR” (CSN), WHICH DEPENDS AND REPORTS DIRECTLY TO THE SPANISH PARLIAMENT.

• COFRENTES NPP RECEIVES AN AVERAGE OF ABOUT 20 CSN INSPECTIONS PER YEAR, COVERING THE MAIN SAFETY RELATED AREAS.

• TWO CSN INSPECTORS (RESIDENT INSPECTORS) ARE WORKING AT THE SITE AND THEY HAVE FREE ACCESS TO ALL PLANT PLACES, LIKE ANY IBERDROLA EMPLOYEE


INTERNAL CONTROL OF COFRENTES NPP

• THE COFRENTES NPP ORGANIZATION INCLUDES A DEPART-MENT OF QUALITY ASSURANCE, WHICH IS RESPONSIBLE FOR THE INTERNAL EVALUATION.

THIS GROUP DEPENDS DIRECTLY FROM THE NUCLEAR PRODUCTION DIRECTION, ASSURING IN THIS WAY ITS INDEPENDENCE OF PLANT OPERATION AND MANTENANCE RELATED GROUPS.

• QUALITY ASSURANCE DEVELOPS ITS WORK THROUGH THE AUDITS AND INSPECTIONS, OF PROCESSES AND ACTIVITIES (AROUND 40 AUDITS PER YEAR)


INTERNATIONAL RELATIONSHIPS OF COFRENTES NPP

• COFRENTES NPP BELONGS TO WANO (WORLD ASSOCIATION OF NUCLEAR OPERATORS). THIS INSTITUTION GATHERS ALL NPP IN THE WORLD AND ITS MISSION IS TO HELP THE PLANTS TO ACHIEVE THE EXCELLENCE BY MEANS OF EXCHANGE OF OPERATING EXPERIENCE AND INDICATORS, TECHNICAL SUPPORT, GOOD PRACTICES AND PEER REVIEW.
