Endesa’s nuclear activities
Endesa has an interest in Nuclear Power Plant Operations in Spain through its shareholdings in following units: Ascó I (100%), Ascó II (85%), Vandellós (72%), Almaraz 1 & 2 (36,021%), Garoña (50%), and Trillo (1%, through Nuclenor). The first five are PWR designed by Westinghouse, Garoña is BWR designed by General Electric and Trillo is PWR designed by KWU. Overall installed nuclear capacity of Endesa is 3.686 MWe, representing 47,1% of the total installed nuclear power in Spain.
These plants are operated by Joint Venture Subsidiaries: Asociación Nuclear Ascó Vandellós II (ANAV – www.anav.es), Centrales Nucleares Almaraz Trillo (CNAT – www.cnat.es) and Nuclenor (www.nuclenor.org), which are also the license holders of the respective power plants.

|Trillo||1066||1%||Centrales Nucleares Almaraz-Trillo, A.I.E. (CNAT)|
Endesa´s governance on these assets is exercised through its role as Shareholder in the respective operating companies: ANAV, Trillo-Almaraz and Nuclenor, and is verified through independent Nuclear Oversight monitoring.
Therefore as a Shareholder, Endesa looks to these organizations to have adopted and implemented appropriate policies and procedures which are consistent with Endesa Nuclear Policy.
Santa Maria de Garoña nuclear power plant has suspended the operation since December 16th, 2012 to avoid a full year of retroactive tax charges for which it would have been liable if it was operating on 1st of January, on the basis of the law 15/2012, dated on December 27th, 2012, which introduced new taxation applicable to energy generation, spent fuel production and radwaste production starting from January 1st , 2013.
The regulatory implementation of the aforementioned law, eliminating retroactive effects of the taxation and the charges to the final core to be unloaded, as well as a modification introduced on the Regulation on Nuclear and Radioactive Installations (RINR), has allowed Nuclenor to request the renewal of its operating license for Santa María de Garoña NPP on May 2014, aiming to extend operation until year 2031, which would represent completing an operating life of 60 years. The Spanish Regulatory Body (CSN) recently finalized the evaluation of the documentation submitted by Nuclenor, and the 8th of February of 2017, issued the corresponding report with the conditions that the plant has to satisfy to be re-started. The report also includes the identification of those improvements in safety that the plant has to implement before fuel reload. This report is preceptive for the Ministerio de Energía, Turismo y Agenda Digital to authorize the operation of the plant, still pending.
Participation in Nuclear Industry Organizations
Endesa encourages membership in nuclear industry international organizations, aiming working together with worldwide utilities and institutions to achieve mutual support, exchange of information and emulation of best practices.
Endesa subsidiary nuclear organizations are members of or participates in several international organizations devoted to strive for Excellence in the operation of nuclear power plants:
- INPO, Institute of Nuclear Power Operations
- WANO, World Association of Nuclear Operators
- NEI, Nuclear Energy Institute (through UNESA)
- EPRI, Electric Power Research Institute (through UNESA)
- Proprietary Groups of Westinghouse and GE
Endesa’s Nuclear Policy
The Board of Directors of Endesa S.A. approved the Endesa Nuclear Policy on February 1, 2011. This policy is summarized in the following statement:
"Through its investments in nuclear technologies, Endesa publicly commits itself as shareholder to ensure that its nuclear facilities adopt a clear nuclear safety policy and are operated with overriding priority to nuclear safety, the protection of nuclear workers, the general public and the environment from risk of harm.
The policy in respect of nuclear safety is to encourage excellence in all plant activities and to go beyond compliance with applicable laws and regulations and to adopt management approaches embodying the principles of Continuous Improvement and Risk Management.
Endesa will ensure to the full extent of its powers as a shareholder that even the relevant nuclear organizations where Endesa has a minority participation have adopted and published suitable policies for nuclear and environmental safety, radioactive waste management and the physical security of nuclear assets. Endesa commits to provide sufficient resources to implement the safety policy. Endesa also commits to a cooperation policy on safety in the nuclear industry worldwide."
Principles supporting Endesa's Nuclear Policy
For the effective implementation of its nuclear policy, Endesa has established the following principles:
- Recognize safety as top priority, using an integrated and consistent approach to all aspects of management to ensure the safe operation of the plants, the physical protection of the facilities and the protection of workers, the public and the environment.
- Promote safety culture at all levels of the organization during all the stages of plant lifetime, which includes identifying and assessing hazards, and minimizing risks, encouraging questioning attitude, prioritizing prudent decisions and fostering an environment in which individuals feel free for raising problems and concerns.
- Promote excellence in the operation, setting expectations that go beyond compliance and encouraging the exchange of experiences within global nuclear industry, the emulation of best practices, the systematic and timely use of operating experience and the use of human error reduction tools, aiming to achieve an event free operation and preventing unplanned plant shutdowns.
- Maintain an excellent material condition at the facilities ensuring that Design Basis standards are met, through proper maintenance programs, systems health monitoring, and also anticipating and managing timely the ageing mechanisms and obsolescence.
- Arrange facilities and human resources needed to ensure sufficient response capabilities to address crisis and emergency situations derived from internal and external events, including extreme situations to respond in an exemplary manner to prevent/minimize any harmful impacts on workers, public, and environment.
- Keep radiation exposure of workers as low as reasonably achievable (ALARA), establishing effective preventive measures to ensure a wide margin with respect to the prescribed limits and stressing the responsibility of each individual with regard to the healthy application of radiation protection principles.
- Ensure that generation of radioactive liquid and gaseous effluents is properly planned and controlled, minimizing the radiological impact on the environment and amply complying with regulatory limits.
- Reduce the volume of radioactive waste generated during plant lifetime, including decommissioning waste, to the minimum reasonably practicable and establish the necessary provisions to comply with regulatory and contractual obligations regarding spent fuel management and decommissioning, facilitating the successive management stages while meeting the safety and radiation protection principles.
- Develop a Human Resources policy that guarantees the preservation of the critical knowledge needed for the safe and efficient operation of the plants and apply a systematic approach to manage training programs of staff and contractors.
- Maintain an Integrated Management System (IMS) consistent with the strategy, policies and objectives of the Organization and linking the different phases of the continuous improvement cycle: planning medium and long term; identifying needs, establishing priorities and allocating resources; executing through core processes, enabling processes and support processes; evaluating through self-assessment and independent evaluation, whether internal or external; and finally defining corrective actions to fix deficiencies and deviations with respect to standards and objectives. Identification and assessment of hazards, as well as management and minimization of risks are performed systematically by thorough deterministic and probabilistic methods, and are embedded in the Integrated Management System at all stages during the lifecycle of the facilities. Prevention of problems, full troubleshooting, follow-up and rectification are ensured by the IMS.
- Ensure that Endesa Nuclear Policy and the principles that support it are consistently applied to contractors and suppliers, establishing the adequate supervision.
- Maintain an internal communication policy that is rigorous, transparent and timely, aiming to strengthen confidence and alignment of the staff with the expectations and objectives of the organization. Maintain also an effective public communication policy, establishing and maintaining open lines of communication with external stakeholders and ensuring the integrity and transparency of the information.
- Ensure the provision of human and material resources to implement effectively all aforementioned principles.
Additionally, in those nuclear power plants where Endesa has a controlling interest, Endesa maintains an independent oversight structure to monitor safe operation of the plants, comprising a high-level committee composed of international experts and a team of permanent oversight assessors on site.
The management of the nuclear assets in which we hold an interest is focussed on integrating the management of nuclear and radioactive safety, occupational risk prevention, the environment, physical protection, quality and economic aspects to ensure the protection of people and the environment.
