Nuclear Assets Management

Our nuclear policy sets out that the safety and protection of workers, the public and the environment is an absolute priority and serves as the basis of our Nuclear Assets Management strategy.

In order to fulfil this policy and ensure transparency in the management of our nuclear activities, at Endesa, we have drawn up the following document:

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%) and Trillo (1%, through Nuclenor). The first five are PWR designed by Westinghouse 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) and Centrales Nucleares Almaraz Trillo (CNAT), which are also the license holders of the respective power plants. 

Endesa exercises the governance on these assets through its role as Administrator in the respective operating companies: ANAV and CNAT and is verified, in the case of Ascó and Vandellós II, through independent Nuclear Oversight monitoring, depending of the Endesa Nuclear General Manager.

Therefore as Administrator, Endesa looks to these organizations to have adopted and implemented appropriate policies and procedures, which are consistent with Endesa Nuclear Policy.
